Description
This class implements glob-style pattern matching as known from Unix shells.
In the pattern string, '*' matches any sequence of characters, '?' matches any single character, [SET] matches any single character in the specified set, [!SET] matches any character not in the specified set.
A set is composed of characters or ranges; a range looks like character hyphen character (as in 0-9 or A-Z). [0-9a-zA-Z_] is the set of characters allowed in C identifiers. Any other character in the pattern must be matched exactly.
To suppress the special syntactic significance of any of '[]*?!-\', and match the character exactly, precede it with a backslash.
All strings are assumed to be UTF-8 encoded.
Member Summary
Member Functions: collect, glob, isDirectory, match, matchAfterAsterisk, matchSet
Enumerations
Options
Flags that modify the matching behavior.
GLOB_DEFAULT = 0x00
default behavior
GLOB_DOT_SPECIAL = 0x01
'*' and '?' do not match '.' at beginning of subject
GLOB_FOLLOW_SYMLINKS = 0x02
follow symbolic links
GLOB_CASELESS = 0x04
ignore case when comparing characters
GLOB_DIRS_ONLY = 0x80
only glob for directories (for internal use only)
Constructors
Glob
Glob(
const std::string & pattern,
int options = 0
);
Creates the Glob, using the given pattern. The pattern must not be an empty string.
If the GLOB_DOT_SPECIAL option is specified, '*' and '?' do not match '.' at the beginning of a matched subject. This is useful for making dot-files invisible in good old Unix-style.
Destructor
~Glob
~Glob();
Destroys the Glob.
Member Functions
glob
static void glob(
const std::string & pathPattern,
std::set < std::string > & files,
int options = 0
);
Creates a set of files that match the given pathPattern.
The path may be give in either Unix, Windows or VMS syntax and is automatically expanded by calling Path::expand().
The pattern may contain wildcard expressions even in intermediate directory names (e.g. /usr/include/*/*.h).
Note that, for obvious reasons, escaping characters in a pattern with a backslash does not work in Windows-style paths.
Directories that for whatever reason cannot be traversed are ignored.
glob
static void glob(
const char * pathPattern,
std::set < std::string > & files,
int options = 0
);
Creates a set of files that match the given pathPattern.
The path may be give in either Unix, Windows or VMS syntax and is automatically expanded by calling Path::expand().
The pattern may contain wildcard expressions even in intermediate directory names (e.g. /usr/include/*/*.h).
Note that, for obvious reasons, escaping characters in a pattern with a backslash does not work in Windows-style paths.
Directories that for whatever reason cannot be traversed are ignored.
glob
static void glob(
const Path & pathPattern,
std::set < std::string > & files,
int options = 0
);
Creates a set of files that match the given pathPattern.
The pattern may contain wildcard expressions even in intermediate directory names (e.g. /usr/include/*/*.h).
Note that, for obvious reasons, escaping characters in a pattern with a backslash does not work in Windows-style paths.
Directories that for whatever reason cannot be traversed are ignored.
glob
static void glob(
const Path & pathPattern,
const Path & basePath,
std::set < std::string > & files,
int options = 0
);
Creates a set of files that match the given pathPattern, starting from basePath.
The pattern may contain wildcard expressions even in intermediate directory names (e.g. /usr/include/*/*.h).
Note that, for obvious reasons, escaping characters in a pattern with a backslash does not work in Windows-style paths.
Directories that for whatever reason cannot be traversed are ignored.
match
bool match(
const std::string & subject
);
Matches the given subject against the glob pattern. Returns true if the subject matches the pattern, false otherwise.

Our vision at Mzamomtsha Primary School is to empower students to acquire, demonstrate,
articulate and value knowledge and skills that will support them, as life-long learners, to
participate in and contribute to the global world and practice the core values of the school:
Respect, Tolerance & Inclusion, and Excellence.
Our mission is to develop students with active and creative minds, a sense of understanding and compassion for others, and the courage to act on their beliefs. We stress the total development of each child: Spiritually, Morally, Intellectually, Socially, Emotionally, and Physically.
Mzamomtsha Primary School is located between Khayelistha Township and uMfuleni Township in the Western Cape Province of the Republic of South Africa. The school's headmaster, Mr. Simphiwe Khuze, joined in 2007. The school is located in a semi-township called Drift Sands which started off as an informal settlement. Drift Sands has since been developed and with support from the South African government it turned into a sprawling township with state of the art housing units. Mzamomtsha Primary School is plays a key role in Drift Sands and is supporting the local community. The school was initially created for primary school students from Grade 1 to Grade 7, but due to the rapid population growth (births and migration) the school is also enrolling higher grades. Students are allowed up to Grade 12 - which is the Matric year. Mzamomtsha School in the remote township of Driftsands has a severe shortage of classrooms and chairs. This follows an early 2018 instruction from the district office for the school to accommodate children who could not fit into overcrowded Mfuleni schools. The Department of Education promised the school mobile classes to help handle the increased learner population, but these have still had not been delivered. Parents organised a protest to highlight the school’s needs, but nothing has changed. Frustrations are growing, and parents are even contemplating closing down the school permanently as they feel the learning conditions their children are enduring are unacceptable.
Simphiwe Khuze is a UWC Graduate who obtained 3 Qualifications at the University. He studied Bachelor of Arts (BA)(1990-1992), Higher Diploma in Education (1993-1993) and Bachelor of Education (199-1994). He started teaching at Mfuleni Combined School as a Teacher (Mar 1994-Apr 1998), he then moved to Manzomthombo SSS in Apr 1998 and left the school in Dec 2000. In Nov 2001, he started marking NSC History Papers, became the Chief Marker and Internal Moderator. He then went back to the school as Head of Department for 2 years. In Apr 2004, he became the Deputy Principal of Manzomthombo SSS, he resigned in Dec 2017 after being offered to be the Principal of Mzamomtsha Primary School. He started at Mzamomtsha in Jan 2018, and has been doing a good job in changing the school around.


While options are available for animating two-dimensional SVG graphics, it is currently simpler just to render the graphic repeatedly with updated parameters. This aspect of the library is left for possible future revision.
The situation with three-dimensional graphics is quite the opposite, since there is already significant overhead in initially loading scenes with current rendering options. The following animation options and suboptions are available for individual objects with the Three.js renderer:
rotation | axis | three-dimensional array of normal vector |
angle | number setting rotation rate |
translation | path | string of three-dimensional array of functions |
step | number setting translation rate | |
argument | defaults to 't' |
Suboptions are input as JavaScript dictionaries under the given option.
The vector determining the translation path
must be entered as a string because JSON cannot process functions. The argument
suboption can be used to specify a variable other than time.
Functions that are not part of standard JavaScript can be included with this command after evaluate()
in the cell template:
injectFunctions( id, { name1: function1, name2: function2, … } )
The name keys are the function names used in the context window of the visualization and their values are references to the function implementations. Only functions explicitly called need to be included: JavaScript automatically handles internal dependencies. For multiple outputs a third argument can specify the number of the target output.
Animations are initiated by setting animate
equal to true
in the output configuration. Animations by default pause for five seconds when the user interacts with the scene, but this can be overridden by setting animateOnInteraction
to true
.
Objects and surfaces can be assigned a group
name in their options
dictionaries for common animation operations.

We show how to estimate the memory reduction obtained by the usage of
Boost.Flyweight in a particular scenario and study the impact on the
execution
time for the different functional areas of flyweight
.
Some experimental results are provided.
我们演示了怎样评估在一个特定的情形下通过使用Boost.Flyweight可以减少的内存用量并且研究了flyweight
各种使用情况下对执行时间的影响。最后给出了一些实验结果。
As we saw in the tutorial rationale, the flyweight pattern is based on two types of objects:
正如我们已经在教程 原理中所看到的，flyweight模式基于2种类型的对象：
The only data member of a flyweight
object is
a so-called
handle, an opaque object of small size provided by
the internal
flyweight factory to refer to the entries it stores. For the default
hashed_factory
,
this handle is merely a pointer, so sizeof(flyweight<T>)=sizeof(void*)
,
4 bytes in typical 32-bit architectures.
For other types of factories, the handle is an iterator to an internal
container used in the implementation of the factory: again, its size
is typically that of a pointer.
flyweight
对象唯一的数据成员是一个所谓的句柄，这是由内部flyweight工厂所提供的一个小型的不透明的对象，用来引用到工厂里存储的entries。对默认的hashed_factory，
这个句柄仅仅是一个指针，因此sizeof(flyweight<T>)=sizeof(void*)
， 通常在32位架构上是4个字节的大小。对其它类型的工厂，该句柄是一个用来实现这个工厂的内部容器的迭代器：同样，它的大小通常是一个指针的大小。
The entries stored in the factory associated to flyweight<T,...>
need not only hold a value of T
, but also
contain additional
information related to the internal implementation of
flyweight<T,...>
:
与flyweight<T,...>
相关联的entries，在工厂中存储时，不仅包含一个T类型的值，
而且还包含与flyweight<T,...>
的内部实现相关的额外信息。
entry = sizeof(T)
+ overhead.
For the current implementation of Boost.Flyweight, the following aspects contribute to overhead:
就Boost.Flyweight目前的实现来说，以下几个方面会增加额外开销：
flyweight
instantiation. Values are given
in words,
i.e. the size of a pointer, which is 4 bytes in a typical 32-bit
architecture.
Alignment may introduce additional overhead.flyweight
实例的各个组成部分各自引起的额外开销。这些值的单位都是字，
换句话说，一个指针的大小，通常在32位架构上是4个字节。对齐可能导致额外的开销。
| component | overhead (words) | |
|---|---|---|
key_value |
with key extractor | 1(1) |
| without key extractor | 1 + sizeof(Key) |
|
| factory | hashed_factory |
~2.5 |
set_factory |
4(2) | |
assoc_container_factory |
depends on the container used | |
| tracking mechanism | refcounted |
2(3) |
no_tracking |
0 |
sizeof(Key)<=sizeof(Value)
.
假定sizeof(Key)<=sizeof(Value)。
std::set
this overhead reduces to 3. 对某些std::set的实现这个额外开销降到3。
For instance, for the default configuration parameters of flyweight
,
overhead is typically 2.5(hashed_factory
)
+ 2(refcounted
)
= 4.5 words.
例如，就flyweight
的默认配置参数而言，额外开销通常是2.5(hashed_factory
)
+ 2(refcounted
)
= 4.5个字。
Consider a scenario where there are N different
objects of type T
jointly taking M different values. The objects
consume then
S = N·T
bytes, where T is defined as the
average size of T
(sizeof(T)
plus dynamic
memory allocated by T
objects).
If we now replace T
by some instantiation
flyweight<T,...>
, the resulting
memory consumption
will be
考虑这样一个场景：N个不同的 T
类型的对象总共占据了M个不同的值。那么这些对象消耗S = N·T字节，T是类型T
的平均大小（sizeof(T)
加上 T
对象动态分配的内存）。如果我们现在用某种flyweight<T,...>
的实例来替换 T
，内存消耗的结果将会是：
SF = N·P + M·(T + overhead),
where P is sizeof(flyweight<T,...>)
,
typically
equal to sizeof(void*)
, as seen before.
The ratio SF / S
is then
在这里P是sizeof(flyweight<T,...>)
，就像之前看到的，通常情况下等于sizeof(void*)
。那么SF / S的比值是
SF / S = (P / T)+ (M / N)(1 + overhead / T).
SF / S
tends to its minimum, P / T,
as M / N tends to 0, i.e. when
the degree of value redundancy
among T
objects grows higher. On the other
hand, the worst possible case
SF / S =
1 + (P + overhead) / T
happens when M / N = 1, that
is, if there is no value redundancy at all; in this situation there is
no point in applying the flyweight pattern in the first place.
当 M / N趋近于0，也就是说，当T
对象的值的冗余度增加的时候，SF / S趋近于它的最小值P / T。另一方面，当M / N = 1，就是说，
根本就没有冗余的值时，出现最差的情形
SF / S =
1 + (P + overhead) / T，这种情况下当初引入flyweight模式就是没意义的。
Fig. 1: Relative memory consumption of Boost.Flyweight as a
function of value diversity.
The introduction of the flyweight pattern involves an extra level of indirection that, in general, results in some execution overhead when accessing the values. On the other hand, manipulation of flyweight objects is considerably faster than moving around the heavy values they stand for. We analyze qualitatively the execution overheads or improvements associated to the different usage contexts of Boost.Flyweight.
引入flyweight模式牵涉到一层额外的间接，通常这会导致在存取值的时候产生一些额外开销。另一方面，操纵flyweight对象要显著快于它们所代表的 重型对象。我们定性地分析Boost.Flyweight在不同使用环境下运行时的额外开销或者改进。
As compared with the initialization an object of type T
,
constructing
a flyweight<T>
performs
important extra work like looking
up the value in the flyweight factory and inserting it if it is not
present.
So, construction of flyweights (other than copy construction, which is
cheap), is expected to be noticeably slower than the construction of
the
underlying type T
. Much of the time spent at
constructing
the associated T
value proper can be saved,
however, by
using key-value
flyweights.
与一个T
类型对象的初始化相比，构造一个
flyweight<T>
要执行重要的额外工作比如在
flyweight工厂里查找值并且在它不存在的时候插入它。因此，flyweights的创建（并非拷贝构造，这要廉价得多），可以预计要显著慢于底层类型T的构造。然而，通过使用键-值flyweight，许多花费在构造T
值本身的时间是可以避免的。
Assignment of flyweight objects is extremely fast, as it only involves
assigning an internal handle type used to refer to the shared value.
Moreover,
assignment of flyweight
objects never throws.
Assignment time
is influenced by the type of tracking
policy used; in this regard,
no_tracking
is the fastest option.
flyweight对象的赋值极快，因为这只涉及到赋值一个引用到共享值的句柄。此外，flyweight
对象的赋值绝不会抛出异
常。赋值的时间受到tracking policy类型的影响；就这一点而言，no_tracking
是最快的选项。
Comparing two flyweight
objects for equality
reduces to
checking that the addresses of the values they are
associated to
are equal; in general, this operation is much faster than comparing the
underlying values. This aspect is of particular relevance when the
flyweight
objects stand for complex values like those arising in the application
of
the composite

对象是否相等降为判断它们所关联的值的地址是否相同；通常情况下，这个操作要远远快过比较底层的值。当flyweight对象
代表的是那些出现在组合模式的应用程序的复杂的值时这个方面特别重要。
The conversion from flyweight<T>
to const T&
relies on a level of indirection relating the flyweight objects to the
values they are associated to; so, value access is expected to be
slower
when using Boost.Flyweight as compared to using the associated values
directly. This overhead, however, can be masked by an indirect
improvement
resulting from locality and cache effects: as the set of different T
values handled by an instantiation of flyweight<T>
is
generally much smaller than the equivalent family of T
objects
when Boost.Flyweight is not used, active values can fit better
into the processor cache.
从flyweight<T>
到const T&
的转换依赖于一层间接——从flyweight对象找到它们所关联的值；因此可以预计，当使用Boost.Flyweight时，值的存取会比直接使用相关的值要慢一些。然而，这种额外负担能够被由于集中和缓存效果带来的间接改进所掩盖：因为一个flyweight<T>
的实例管理的不同T
值的集合通常要比没有使用Boost.Flyweight 时等价的T
对象的家族小得多，活动的值可以更好的适应处理器的缓存。
A profiling program
was devised to test
the space and time efficiency of different instantiations of flyweight
against a base situation not using Boost.Flyweight. The profiled
scenarios are:
设计了一个分析程序以不使用Boost.Flyweight的情况作为基数来对比测试不同flyweight
实例的空间和时间效率。这些分析场景是：
std::string
.flyweight<std::string>
with default configuration aspects (hashed_factory
,
refcounted
tracking, simple_locking
).
flyweight<std::string,no_tracking
>
.flyweight<std::string,set_factory
>
.flyweight<std::string,set_factory
,no_tracking
>
.Actually the types tested are not exactly those listed above, but instrumented versions that keep track of the allocated memory for profiling purposes. The program parses a text file into an array of words and then perform various manipulations involving the different context usages of Boost.Flyweight discussed previously. As our text file we have used the plain text version of Project Gutenberg edition of Don Quijote (2.04 MB).
实际测试的类型和上面列出来的不完全一致，而是修改后的可以跟踪内存分配的版本用以分析。该程序分析一个文本文件并将结果保存在一个单词数组里然后进行各种操作，涉及到前面讨论的Boost.Flyweight的各种使用环境。我们使用Don Quijote的Project Gutenberg版本的纯文本格式(2.04 MB)作为我们的文本文件。
The program was built with default release settings and _SECURE_SCL=0
.
Tests were run under Windows XP in a machine equipped with an Intel
Core 2 Duo T5500
processor and 1 GB of RAM.
程序使用默认的release设置编译，并且设置_SECURE_SCL
选项为0。测试程序运行在一台配备了Intel
Core 2 Duo T5500和1GB内存的Windwos XP机器上。
Fig. 2: Memory consumption, MSVC++ 8.0. Values in MB.
The results show the memory consumption figures for the different
profiled
scenarios.
The standard library implementation of MSVC++ 8.0 features the
so-called
small buffer optimization for strings, by which std::string
objects hold a small buffer that can be used when the string is short,
thus avoding dynamic allocations. This results in sizeof(std::string)
being quite high, 28 bytes. In our particular test strings are almost
always
held in the small buffer, so the minimum SF
/ S
achievable is 4/28 = 14.3%, which is quite close to the experimental
results, given that the memory devoted to storage of shared values
is residual (around 3% of total memory) due to the high word redundancy
of the text source.
这个结果显示了不同的分析场景下内存消耗指标。MSVC++8.0的标准库实现了一个所谓的针对字符串的小缓冲区优化，当字符串较短的时候可以直接存储在std::string
自带的这个小缓冲区里，于是避免了动态分配。这导致sizeof(std::string)
相当高，有28个字节。在我们这个测试里字符串几乎总是存储在这个小的缓冲区里，因此SF
/ S可以达因此到的最小值是4/28 = 14.3%，这跟实验结果相当接近了，由于原文中单词高度的冗余，用来存储共享值的内存不值一提（大概占总内存的3%）。
Fig. 3: Execution time, MSVC++ 8.0. Values in seconds.
The figure displays execution times for the profiled scenarios in
different
usage contexts. In accordance with our previous
qualitative analysis,
initialization of flyweight
s
carries an important overhead with respect to the base case scenario
(between 20% and 40%
of additional execution time), while the other usage contexts
(assignment, equality comparison and value access) have performance
gains,
with speedup factors of more than 10 in some cases. The use of a refcounted
tracking policy introduces penalties with respect to
no_tracking
in initialization and assignment, but has no effect in equality
comparison
and value access.
这幅图显示了不同的分析场景在各种使用环境下的执行时间。与我们之前的定性分析一致，与比较基数相比flyweight
s的初始化有一个明显的额外开销（20% 到 40%的额外执行时间不等 ），然而其它的使用环境下（赋值，判等和值存取）获得了性能的提升，在某些情况下加速系数高于10。与no_tracking
跟踪策略相比refcounted
跟踪策略在初始化和赋值时性能有所下降，但是在判等和值存取方面没有什么区别。
The Cygwin/MinGW version of the compiler was used, with command options
-ftemplate-depth-128 -O3 -finline-functions -DNDEBUG
.
Tests were run under a Cygwin terminal in the same machine as before.
使用的是Cygwin/MinGW里的版本，带有-ftemplate-depth-128 -O3 -finline-functions -DNDEBUG
选项。
测试程序运行的Cygwin终端和之前的测试在同一台机器上。
Fig. 4: Memory consumption, GCC 3.4.4. Values in MB.
The standard library used by GCC 3.4.4 implements std::string
using copy-on-write
optimization techniques, which leads to very small value redundancy for
some usage patterns. This explains why the memory reduction achieved
by Boost.Flyweight is so poor in this case. Other contexts where
assignment
is much less used than direct construction will favor Boost.Flyweight
over plain copy-on-write std::string
s.
GCC 3.4.4使用的标准库实现std::string
时使用了写拷贝优化技术，导致在某些使用方式下冗余的值非常少。这解释了为什么在这种条件下使用Boost.Flyweight所减少的内存少的可怜。在那些更多的采用直接构造而非赋值的使用环境下，Boost.Flyweight的表现优于普通的写拷贝std::string
s。
Fig. 5: Execution time, GCC 3.4.4. Values in seconds.
Relative performance figures are similar to those obtained for
MSVC++ 8.0, although
some of the
speedups achieved by Boost.Flyweight are higher here (×25
in equality comparison and up to ×100 in assignment when
no_tracking
is in effect).
相关的性能指标与MSVC++ 8.0的结果类似， 然而这次某些使用Boost.Flyweight获得的加速效果更高（判等时提高了25倍当使用no_tracking
时赋值提高了100倍）。
The introduction of Boost.Flyweight in application scenarios with very
high value redundancy yields important reductions in memory
consumption:
this is especially relevant when data volume approaches the limits of
physical memory in the machine, since Boost.Flyweight can avoid virtual
memory thrashing thus making the application viable. We have shown
how to estimate the achievable reduction in memory consumption from
some basic value statistics and knowledge of the flyweight
configuration aspects being used.
在值冗余非常高的应用场合使用Boost.Flyweight可以显著减少内存用量：尤其是当数据量达到机器物理内存限制的时候，因为
Boost.Flyweight可以避免虚拟内存震荡于是让应用程序可用性更强。我们已经演示了怎样评估可以减少的内存用量，通过一些基本的统计数字和使用到配
置的flyweight
选项知识。
Boost.Flyweight can also accelerate execution times in areas other than object initialization, due to the fastest manipulation of small flyweight objects and to locality and cache effects arising from the drastic reduction of the set of allocated values.
Boost.Flyweight可以加速除了对象初始化以外的执行速度，因为操纵小型的flyweight对象很快，还有因为所分配的值的集合急剧减少带来的集中和缓存效果。

Description
This class provides the tools to compute the Fast Fourier Transform of any function, which is assumed to be a periodic sequence of logarithmically spaced points. It is inspired on the approach FFTLog developed by Hamilton (2000) [arXiv], which was extended as described below.
A function $G(r)$ is written as \begin{equation}\label{eq:Gr} G(r) = \int_0^\infty F(k) \ K(kr) dk, \end{equation} where $F(k)$ is defined in the fundamental interval $[\ln k_0 - L/2, \ln k_0 + L/2]$, $L$ is the period, $\ln k_0$ is the center value and $K(kr)$ is a kernel function. Assuming that $F(k)$ can be written in terms of the $N$ lowest Fourier modes, we have
$$F(k) = \sum_{n} c_n e^{\frac{2\pi i n}{L} \ln\left(\frac{k}{k_0}\right)}.$$ Substituting $F(k)$ in Eq. \eqref{eq:Gr} and changing the variable $k \rightarrow t = kr$, thus \begin{align}\label{eq:Gr_decomp} r G(r) &= \sum_n c_n \int_0^\infty \frac{k}{k_0}^{\frac{2\pi i n}{L}} K(kr)^2 d(kr) \ &= \sum_n c_n \int_0^\infty \frac{t}{k_0 r}^{\frac{2\pi i n}{L}} K(t) dt \ &= \sum_n c_n e^{-\frac{2\pi i n}{L} \ln\left(\frac{r}{r_0}\right)} e^{-\frac{2\pi i n}{L} \ln(k_0 r_0)} Y_n, \end{align} where $$Y_n = \int_0^\infty t^{\frac{2\pi i n}{L}} K(t) dt,$$ and the Fourier coefficients are $$c_n = \frac{1}{N} \sum_m F(k_m) e^{- \frac{2\pi i nm}{N}}.$$ The total number of points $N$ corresponds to the number of knots in the fundamental interval, which is equally spaced.
The variables discretization is different depending whether $N$ is even or odd, in general $$ k_n = k_0 \mathrm{e}^{n L / N}, \qquad r_m = r_0 \mathrm{e}^{m L / N}. $$ If $N$ is odd, $n$ and $m$ runs from $[-\lfloor N/2\rfloor, \lfloor N/2\rfloor]$, where $\lfloor N/2\rfloor$ is the round-down (largest integer smaller than $N/2$) of $N/2$. In this case \begin{align} \ln\left(k_{-\lfloor N/2\rfloor}\right) = \ln(k_0) - \frac{(N-1)}{N} \frac{L}{2}, \ \ln\left(k_{+\lfloor N/2\rfloor}\right) = \ln(k_0) + \frac{(N-1)}{N} \frac{L}{2}. \end{align} This means that for odd $N$ the values of $k_n$ (and $r_n$) never touches the borders $\ln(k_0) \pm L/2$ and $\ln(r_0) \pm L/2$. On the other hand if $N$ is even ($\lfloor N/2\rfloor = N/2$) \begin{align} \ln\left(k_{-\lfloor N/2\rfloor}\right) = \ln(k_0) - \frac{L}{2}, \ \ln\left(k_{+\lfloor N/2\rfloor}\right) = \ln(k_0) + \frac{L}{2}. \end{align} However, since we are assuming that these functions are periodic with period $L$ these two points refer to the same value of the functions. Thus, we do not need to include both points and in the case of even $N$ we include the point $\ln(k_0) - \frac{L}{2}$ only. In the original FFTLog paper they include both points but give them a $1/2$ weight, here we avoid this complication by using the lower end point only.
The user must provide the following input values: $\ln k_0$ - ncm_fftlog_set_lnk0()
, $\ln r_0$ - ncm_fftlog_set_lnr0()
,
$L$ - ncm_fftlog_set_length()
, padding percentage - ncm_fftlog_set_padding()
, $N$ - ncm_fftlog_set_size()
,
$F(k)$ (or $F(k_m)$ -- see description below).
Since the algorithm assumes that the function to be decomposed is periodic, it is worth extending the interval in $\ln k$ such that $F(k) \equiv 0$ in the intervals $\left[\ln k_0 -\frac{L_T}{2}, \ln k_0 - \frac{L}{2} \right)$ and $ \left(\ln k_0 + \frac{L}{2}, \ln k_0 + \frac{L_T}{2}\right]$, where the total period $L_T$ is defined by the final number of knots, i.e., $N_f = N (1 + \mathrm{padding})$.
$N$ knots are equally distributed in the fundamental interval and $N \times \mathrm{padding}$ knots are distributed in the two simetric intervals as mentioned above.
For the sake of optimization, the final number of points $N_f$ is substituted by the smallest number $N_f^\prime$ (bigger than $N_f$) which can be decomposed as $N_f \leq N_f^\prime = N^\prime (1 + \mathrm{padding}) = 2^a 3^b 5^c 7^d$, where $a$, $b$, $c$ and $d$ are positive integers.
-
The function $F(k)$ can be provided as:
a gsl_function -
ncm_fftlog_eval_by_gsl_function()
- whose values are computed at the knots within the fundamental interval, and set to zero within the padding intervals.as a vector -
ncm_fftlog_eval_by_vector()
- first one must get the vector of $\ln k$ knots,ncm_fftlog_get_lnk_vector()
, and then pass a vector containing the values of the function computed at each knot.
Regarding $Y_n$, see the different implementations of NcmFftlog, e.g., NcmFftlogTophatwin2 and NcmFftlogGausswin2.

You can define multiple mappings within a single binding, as already demonstrated in the last collections examples. These mappings may all be top-level (children of the binding element), or may be nested within other mapping definitions. Nested mapping definitions are only usable within the context of the containing mapping. In general, it's not a good idea to nest mapping definitions more than one level deep, or inside mappings other than the one used for the root element of your documents, because of performance concerns.
Figure 12 is a trivial example of using multiple
mappings. The first mapping in this example binds the root customer
element to the Customer
class. The second
mapping, highlighted in green, binds address elements to the
Address
class. The empty structure element (with no child
elements) for the address
field, both shown in blue, automatically
uses the mapping defined for the Address
class because that is the
type of the field referenced by the structure element.
Using empty structure elements to reference mappings, as shown in Figure 12, is most useful when an object reference can be to instances of different classes. When there's no mapping defined for the exact type of the object reference associated with the structure, but there are one or more mappings for assignment-compatible types (such as subclasses), JiBX will accept any of the assignment-compatible types at runtime and use the appropriate mapping.
Figure 13 demonstrates using an empty
structure element with no mapping matching the object type. The
only change from the last example is that I changed
the type of the address
field to java.lang.Object
(highlighted in green). The same document is still marshalled and unmarshalled,
but there is a subtle difference between the two examples: The
Figure 13 binding will allow the address
field to reference an instance of any mapped class, including another
instance of the Customer
class. This flexibility may not be what
we want in this case (since the field is named "address"), but it fits the field
definition.
You can force an empty structure element to use a particular mapping with the map-as attribute. This restricts the value for the referenced object to always be of the type of that mapping. It's generally a good idea to use map-as when you're expecting to use a specific mapping, even when JiBX will automatically select that mapping (as in Figure 12), just to make the linkage to a particular mapping explicit and avoid any potential confusion. I'll show some examples of using the map-as attribute later on this page.
All the mapping examples I've used so far are normal mappings, each relating an element name to instances of a particular class. JiBX also lets you define abstract mappings, which are essentially anonymous bindings for classes. Abstract mappings can be referenced from different contexts with different element names, or with no name at all. Figure 14 shows an example using an abstract mapping.
Figure 14. Simple abstract mappingThis binding defines normal mappings for two classes, the Customer
class and the Subscriber
class. The abstract mapping for the
Address
class, highlighted in blue, defines the basic XML structure
used to represent an address. The Customer
mapping includes a pair
of structure elements (highlighted in green and red) that define
element names for the two Address
components of a customer, so
within the corresponding customer element these components are each bound
to separate child elements. The Subscriber
mapping uses a single
structure element (highlighted in magenta) with no element name for its
Address
component, so the address information is in this case
merged directly into the representation of the corresponding subscriber
element.
You can define multiple abstract mappings for the same class, using names to
distinguish between the mappings. Figure 15 shows a
modified version of the last example, where I've defined two different abstract
mappings for the Address
class. The first abstract mapping,
highlighted in blue, is the same as the Address
mapping in the
last example except for the addition of a type-name of "normal-address".
The second abstract mapping, highlighted in green, uses a different structure
and a type-name of "compact-address". Each structure reference to
a Address
object has also been changed, as highlighted in magenta,
to reference one of the two abstract mapping names using a map-as
attribute.
The Figure 15 changes have no effect on the document
with the customer root element, since the abstract mapping used for the
Address
instances in this context remains the same. But the
document with the subscription root element has a very different
structure from the previous example, as defined by the alternative abstract
mapping for the Address
class.
You can use interfaces as well as regular classes for abstract mappings, which is useful when the interface defines get/set methods to be used by the mapping. You can also use interfaces and abstract classes with a normal mapping definition in some circumstances - the basic requirement here is that there has to be a way to create an instance of the interface or abstract class when unmarshalling (as with a factory method, discussed in User extension method hooks).
mapping definitions are normally used for your own data classes, and those classes are directly modified by the JiBX binding compiler. You can also define mappings for unmodifiable classes, such as system classes or ones in jar files (though you can make the classes from a jar file modifiable by just unpacking the jar before running the binding compiler, then repacking it after). When a mapping is defined for an unmodifiable class, the mapping can only be used within the context of some other mapping.
Besides the "free standing" mappings you've seen so far, you can also define extension mappings which are linked to other mappings. Each extension mapping references some base mapping. By attaching itself to that base mapping, the extension mapping becomes an alternative to the base mapping anywhere the base mapping is invoked in the binding. When marshalling, the actual type of the object instance determines which mapping is applied, and hence the element name (and actual representation) used in the generated XML. When unmarshalling, the element name is used to select the extension mapping to be applied and hence the type of object to be used for the unmarshalled data.
Extension is easiest in the case where the base mapping class is never used directly. In this case you can define an abstract mapping as the root for extension, then add normal mappings which extend that abstract mapping for each substitute you want to allow in your binding. Figure 16 shows a simple example of this approach, with a base class containing some common information and a pair of subclasses providing additional details. This sort of polymorphic class hierarchy is a common use case for extension, but not the only use case.
Figure 16. Abstract and extension mappingsIn Figure 16 I've changed my earlier example code to
support two types of customers, persons and companies. The Customer
class doesn't care which is used, it just includes a reference to an instance of
the Identity
class. The Identity
itself only defines a
customer number. The Person
and Company
classes each
extend Identity
with added information for their particular
type.
I've highlighted the handling of the base Identity
class in
blue, with the Person
handling
in green and the Company
extension in magenta. The mapping
definitions for the subclasses in this case each invoke the base class abstract
mapping as part of their bindings (using a <structure map-as="...">
reference). This is not a requirement of using extension mappings; in fact,
there's no requirement that the extension mapping classes are even related to
the base mapping class. Likewise, you don't need to use "extends" in order to
reference a base class mapping in this way - extends is only necessary (or
appropriate) in cases where instances are being used polymorphically, as in the
reference from the Customer
class in this example.
The base for an extension mapping doesn't have to be an abstract mapping. It's generally easiest to structure your extensions to use an abstract base when you can, but there are cases where that's just not possible. For example, if instances of your base mapping class can be used directly (rather than only instances of the extension mapping classes), you need to define a concrete mapping for that root class. Figure 17 gives an example of this situation, again using a set of related classes.
Figure 17. Extending a concrete mappingThe difference from the last example is that in
Figure 17 the base Identity
class can be
used directly, as shown by the added example document (highlighted in magenta).
Since the base class can be used directly I had to define a concrete mapping
for the class, and make the subclass mappings extend the base mapping
(highlighted in green). I couldn't just invoke this base class mapping in the
subclass mappings, though, since the base mapping includes the base-ident
element name - invoking it directly would correspond to an XML structure where
the entire base-ident element was embedded within the subclass
representations. Instead, I used a separate named abstract mapping to represent
the structure I wanted for the base class information, and invoked this abstact
mapping from both the base mapping and the subclass mappings.
Even though the original intention of extension mappings was to represent polymorphism, they can also be used in other circumstances - there's no requirement that the classes handled by the extension mappings have any particular inheritance or implements relationship to the class handled by the base mapping. This flexibility can be useful when working with XML representations which assume a particular inheritance structure (in the form of substitution groups) that doesn't match the intent of your application code.
This page covers most of the mapping element options and usage, but see the <mapping> element details page for full details.

Cardano delegation model includes a mechanism to punish nodes for imperfect performance.
More specifically, if a node (or pool) wins a certain amount of slots N
for an epoch, but misses some of them and creates only n < N
blocks.
Then this node will be punished by reducing its total reward (so all the stakeholders
who delegated to the pool are losing profits) and by reducing its rating for future
epoch selections.
This demo-page is for the formula that is used to determine the actual reward of a pool, considering the punishment. This formula is used after the main pool reward formula. This means that at first the "raw" reward is calculated by the main formula, and then this punishment formula is applied to see if the raw reward should be reduced.
"Number of slots owned" (N)
- how many slots did the node won at the beginning
of the epoch. These slots are considered to be "owned" by this node, and the node is
supposed to create the same amount of blocks. This number cannot be smaller than
number of created blocks (n)
.
"Number of created blocks" (n)
- how much actual blocks were created
by the node. This number cannot be larger than number of owned slots (N)
.
"Raw pool rewards" (f(s,o))
- the raw reward, earned by this pool
based on its stake. You can use specific separate
demo page to see how this works.
"penalty severity" (y)
- a system constant. This parameter determines,
how severely the node will be punished depending on how many slots are missed.
You can see different values of this parameter being plotted on the chart.
This formula is taken from the official reward scheme paper: Calculator Documentation
These two charts show how resulting pool reward is affected by changing
h
and y
values. You can try changing the y
value and see how charts respond.
y
as n
grows (left or top chart)
On this chart you can see different values of y
being plotted
at different number of blocks (n)
being created. Each line represents
a different system, where constant y
is selected at different value.
You can change the number of slots (N)
value in the input form and see
how chart changes.
Chart clearly shows that at n=0
any value of y
gives
the resulting reward of 0 (except the very special case of y=0
,
which means that no punishment will be applied at all). This means that no matter
what is the punishment severity - it is impossible to get a reward for making no
blocks at all.
Next you can clearly see a straight middle line that goes diagonally between bottom-left
and top-right corners. This line represents value of y=1
when punishment
is perfectly proportional to the performance - if a node has created 50% of it's blocks,
then it will receive 50% of raw rewards, etc.
All lines above the middle-line represent values of y < 1
.
You can see how with these values node would receive lower punishment at higher
number of created blocks (few missed blocks), but then as number of created blocks
goes down - punishment gets more severe, resulting in the same zero value.
On the other side, all lines under the middle-line represent values of
y > 1
and bend in opposite direction. This means that the larger
value of y
gets - the more severely punished first missed slots become.
You can see how at y=10
first 5 missed blocks (n=95)
already gets the node only ~60%
of the raw reward.
N
as n
grows (right or bottom chart)
On this chart each line represents a node\pool with different amount of slots
they have won for the passed epoch, and x-axis represents how many blocks they
have actually created. So leftmost line represents a pool that have won 20 slots
(or 20% of slots, if you have N>100
). You cann see 5 points on this line,
representing its reward if has produced: 0
, N/4
, N/2
,
3N/4
, or N
blocks. All other lines represent similar steps
for nodes with larger amount of owned slots.
If you change the y
value in the input form, you will see the chart respond.
Doing so you can clearly notice the "middle-line" of rewards, consisting of points
representing 50% of blocks in the middle of each line (this middle-line falls exactly
at 50% reward at y=1
). So you can move y
value around
and see, how nodes of different size would be relatively compensated if they miss
a quoter, or a half of its slots.
Selecting right y
value is a complex task, because it determines the
"forgiveness" of the system. With smaller values of y
nodes can
easier miss few blocks and not lose that much profits, but again as number
of created blocks goes down - mild y
appears to be less and less fair,
because even by missing 50% of slots nodes still receive >50% of rewards.
On the other hand, larger values of y
impose more severe punishment
for nodes as they miss more blocks, but at the same time it may cause the punishment
to be "too severe" for small nodes that miss few blocks.
Right value is for the IOHK to select, depending on what kind of behaviour they want to model for the system.


In junior year, I had to "write" many LabView programs for the Digital Electronic class and lab. Some of them include integrated circuit chip emulation, serial communication through fiber optic cable using DAQ, and motor speed control.
However, being someone who had previous background in programming (in python and java), I found graphical programming time-consuming and limited. Although it is great at quickly whipping up decent graphical UI, it did not seem to be geared for serious programming.
Due to these facts I decided to research "text based coding in LabView" and present it to the class.
For the LabView 2011, there were four different methods in which to use text-based coding:
I decided to take a simple and comical program as an example. The program was simulating the projection of an object thrown upward at a user given velocity, where the object was an image of a cat.
I implemented the same program 4 times, using the aforementioned text-based coding methods within LabView.
There is a graphical element within LabView called the "formula node", placing this element onto the block diagram will take a form of a text-box that can be connected to input and output elements.
Below is the image of the cat jump program implemented with the formula node:
The text code allowed for the formula node is reminiscent of a very simplified version of C with built in arithmetic functions. The list of available functions are detailed in this site.
The Mathscript was previously included with the standard LabView purchase, but since LabView 2011, it needs to be purchased separately. I could not get the evaluation copy to work for me. The general principle is same as the mathscript, but with greater funtionality and designed specific for LabView.
An example of mathscript node is shown below:
The mathscript module can be downloaded from the National Instruments site.
More information and tutorials can be found in the following links:
http://zone.ni.com/devzone/cda/tut/p/id/6206#toc2
http://zone.ni.com/devzone/cda/tut/p/id/3256#toc1
There is a programming language platform called Matlab that is frequently used for complex calculations and mathematical analysis. If you have access to Matlab, then you can use the matlab node in labview to do computations through matlab.
Below is the image of the same cat jump program implemented using the matlab script node.
As you can see, the setup is very similar to mathscript and the formula node. The matlab node will send the typed script to the matlab server running locally on the machine, and then the server will run the script and return the result to the Labview.
LabView has an element called the "call library function node". This node allows you to use a function/method that is defined in a DLL file written using C or C++. Each node can be used for one function within the DLL.
Below is the cat jump program implemented using the call library function node:
And below is the source of the DLL that I wrote:
The last two functions in the code are what is used in the labview, and all other are essentially necessary setup for DLL compilation.
A quick tutorial on how to use the DLL with labview is found here.
A free programming IDE for C/C++ can be found here.
In the table below, I compare each of the methods according to the various criteria.
| Space Efficiency | Coding Speed | Capability | Debug | Variable types | Ease of Use | Cost | |
|---|---|---|---|---|---|---|---|
| Graphical | 1/5 | 2/5 | 4/5 | 5/5 | 5/5 | 5/5 | 5/5 |

| DLL (C/C++) | 3/5 | 2/5 | 5/5 | 1/5 | 3/5 | 1/5 | 5/5 |

Villagers protest over dead body in Godavari
Govt. hospital staff blamed for dumping it
by Special CorrespondentAn unknown and partly putrified body found close to the Godavari river under the old bridge at Gudem in Luxettipet mandal of Mancherial district had Gudem villagers staging a rasta roko on the Luxettipet-Karimnagar road on Saturday. The villagers accused the staff of Government Civil Hospital, Luxettipet, of abandoning the body under the cover of darkness and feared it could spread diseases through the river. The villagers alleged that the unknown person had admitted himself to the hospital three days back which, according to them was evident as the dead body was kept on a bedsheet carrying the hospital name. As the disease of the patient could not be diagnosed, the hospital staff abandoned him under the bridge and he subsequently died.
The villagers were apprehensive of the fact that the purtrifying dead body could become cause of disease spread. They relented after Luxettipet Sub Inspector of Police Vijay Kumar assured them that the matter would be looked into.

I tried to testify at the last commission hearings but was not allowed to due to time, no member of the commission held any public forums in my area. So my voice and my neighboring areas did not get any input. Redistricting is very important and it must take into account geography, the access to services, languages and economic situations. This is essential not only to Colorado, but also how it affects the national interaction with government. This is a time consuming commission and is needed to ensure a fair representation of the constituents in those districts.
Unfortunately there will never be a 100% agreement on the lines, this is okay as long as the commissioners can interact as responsible and impartial on the commission. As in working in a retail store that deals with all different personalities and backgrounds you must be direct and polite and be able to listen to the reasoning as to why the congressional district boundaries should stay the same or alter. It is not easy to be impartial but the commission must always remember that it is about all the constituents in the districts and not personal. I can tell you from going to the redistricting hearing for the house seats it was heated but cordial as I listened to the commissioners and those individuals testifying it was not easy as I sat in the gallery myself.
Helping to run a 3 million dollar a year business I must look at the numbers for the business, but also be able to take into account circumstances such as environment, future interactions, word of mouth, social media and the bottom line. I coached Ice Hockey for 19 years from 5 year olds to 23 year olds in college dealing with parents and school administrations was unique and fun.

The population of Lions are decreasing dramatically. More than 80% of the World's lion population have died in the past few decades. The majority of these deaths came from trophy hunters and exotic animal trade. According to change.org two thirds of the lion trophies ended up in the United States over the past 10 years. This is a Shameful. If this tread continues in a short decades, there would be no Lions in the World. The King without a prey is endagered!

Angular 2 DateTimepicker is a cool responsive DateTimepicker component for Web and Mobile. It is Mobile friendly and light weight. Developed by Cuppa Labs.
To get started with using the multiselect dropdown component, follow the below steps. It’s easy to integrate and just a matter of minutes.
npm install angular2-datetimepicker
Import AngularDateTimePickerModule
into your AppModule
import { AngularDateTimePickerModule } from 'angular2-datetimepicker';
@NgModule({
// ...
imports: [
AngularDateTimePickerModule,
]
// ...
})
Declare the component data variables and options in your component where you want to consume the dropdown component.
import { Component, OnInit } from '@angular/core';
export class AppComponent implements OnInit {
date: Date = new Date();
settings = {
bigBanner: true,
timePicker: false,
format: 'dd-MM-yyyy',
defaultOpen: true
}
constructor(){}
ngOnInit(){
}
}
Add the following component tag in the template where your want to place the datepicker
<angular2-date-picker [(ngModel)]="date" [settings]="settings"></angular2-date-picker>
Following settings
object properties can be used to configure the component.
| Property | Type | Default | Description |
|---|---|---|---|
| format | String | dd-MMM-yyyy hh:mm a | Date format of the selected date. |
| bigBanner | Boolean | true | The banner section to show the date details. |
| defaultOpen | Boolean | false | To open the datepicker popover on load. Default is set to false. |
| timePicker | Boolean | false | Enable time picker feature. |
| closeOnSelect | Boolean | true | to close the popover on date select or on click of done button. |
onDateSelect
Define a callback method to be called on select of the date.
<angular2-date-picker (onDateSelect)="onDateSelect($event)"
[(ngModel)]="date"
[settings]="settings" >
</angular2-date-picker>
format string can be composed of the following elements:
format string can also be one of the following predefined localizable formats:
‘medium’: equivalent to ‘MMM d, y h:mm:ss a’ for en_US locale (e.g. Sep 3, 2010 12:05:08 PM)

Detailed Description
Depth-first path (stack of edges) supporting recomputation.
Maintains the invariant that it contains the path of the node being currently explored. This is required to support recomputation, of course.
The path supports adaptive recomputation controlled by the value of a_d: only if the recomputation distance is at least this large, an additional clone is created.

Azure is a robust collection of integrated cloud services from Microsoft. Their goal is to offer users a flexible and efficient cloud platform that you can run anywhere. Before we walk through the instructions on how to deploy Your Awesome App on Azure, please have both a Microsoft Azure Account and Azure CLI tool belt installed.
Ready? Let's get started!
Log in to Azure from the command line:
$ azure login
You'll be redirected to a browser to continue logging. Sign in using the browser and you'll receive a success message in your terminal, letting you know what info: login command OK
.
Create the App Service app resource with a unique app name with this simple Azure tutorial, created by Microsoft:
Sign in to the Azure portal with your Azure account. From the left menu, click New > Web + Mobile > Web App
.
In the app creation blade, use the following settings for your new app:
Create new
and give the resource group a name.Create New
to set the name, location, and pricing tier of the App Service plan. (Feel free to use the Free pricing tier).Create
at the bottom. You can click the Notification
icon at the top to see the progress.Deployment succeeded
blade, click the Resource
link to open your new web app's blade.Getting Ready to Deploy:

or search for it, then click it.Choose Source > Local Git Repository > OK
.Deployment credentials
.Properties
or search for it, then click it. Next to Git URL
, click the Copy
button.Now, let's deploy some code to Azure using Git:
In your command-line, make a new directory, with a different name and clone this sample app, https://github.com/Azure-Samples/app-service-web-html-get-started
, like this:
git clone https://github.com/Azure-Samples/app-service-web-html-get-started
Cd into this sample app
$ cd app-service-web-html-get-started
Configure the Git remote for your Azure app its Git URL, which you copied from the Portal a few steps ago.
$ git remote add azure <copied-git-url-from-your-portal>
Deploy your code to your Azure app:
$ git push azure master
To make updates use the following steps:
$ git add .
$ git commit -m "Updates Azure App Service"
$ git push azure master
In your browser, navigate to http://
