Hi
I have built one of Robins Mk2 which is working very well, I have now added a de-stratification pump to my DHW tank. When its working it works very well but the pump seems to get full of air or maybe forms a vacuum and no longer moves water, I have fitted a speed controller so that I can run the pump as slow as possible but it still fails. See below my setup, the pump I have used is from Ebay.
Any thoughts from those who have already fitted successful systems, will an self venting air bleed valve do anything?
After hours of draining & plumbing, So close!
Kind regards, Dave
Re: de-stratification setup installed, help / advice required
Hi Dave
Just wondered what you're rationale was in pumping from top to bottom.
I'd always thought about pumping cold water up from the bottom of the tank to avoid the pump having to deal with water potentially close to boiling point.
(I haven't got around to installing my pump yet!)
Paul
Re: de-stratification setup installed, help / advice required
Hello Dave,
Sounds like your pump is cavitating. (think water boiling at a lower temperature at altitude)
Since the water at your pump inlet is hot, the negative pressure created by the pump makes the water want to "boil," resulting in cavitation, and loss of water circulation.
Ref: http://www.micropump.com/support_cavitation.aspx
Reversing the pump direction and pushing cooler water from the bottom of the tank to the top should resolve your issue. Locating your pump inlet as close to the bottom of the tank will help by ensuring sufficient pressure at the pump inlet.
Regards,
Bill
Re: de-stratification setup installed, help / advice required
Thanks for your responses, I have seen posts of other pumping from bottom to the top but if you do that then what stops the feed to the shower pulling cold water from the bottom of the tank?
Re: de-stratification setup installed, help / advice required
what stops the feed to the shower pulling cold water from the bottom of the tank?
That's a "gotcha." In that case, you'll definitely want to locate the pump inlet as near to the bottom of the tank as possible. (present pump flow direction unchanged)
However, once the tank is destratified, the difference between top and bottom temps might be small enough that the "colder" water getting pulled from the bottom of the tank wouldn't be an issue.
I ran one of Robin's Mk2 routers (good stuff!) and used a pond pump to de-strat a 55 Gallon drum of water used as a dump load. The pump sat on the bottom of the barrel. On one particular sunny day, the water temp at the bottom rose to the point it deformed the plastic pump housing rendering the pump useless. Measured with an IR "laser spot" type thermometer, the drum exterior temp near the bottom was ~90C.
Re: de-stratification setup installed, help / advice required
Hi, have changed the pump around and it sounds and moves water a lot lot better, will try tomorrow if we have sun.
Does this mean that as the water temperature at the bottom of the tank rises then cavitation may re occur?
or
is it that pressure is better now the pump is that way around?
BTW I ran the shower and no water was draw up through the de-strat pump, I believe its because new cold water is being fed into the bottom of the tank to replace the water being used by the shower, on the grounds that "water out" must equal "water in" then there is no reason it should take water thorough the smaller pipe.
Re: de-stratification setup installed, help / advice required
The hotter the water gets, flowing through the pump, the greater chance of cavitation.
I would expect though that by fitting a restricter valve in the pump output pipe would lessen the pressure difference between the pump input and output (because system water pressure will have greater chance of replacing the water drawn into the pump), thereby reducing cavitation - is this your understanding Bill?
Are you intending to run the pump continuously, or do you have some sort of control system to actuate the pump when a certain criteria is met? I'm sure that you will have considered the consequences of destratification on a cloudy day (luke warm showers!)
Paul
Re: de-stratification setup installed, help / advice required
Hi Paul
Yes I will build a controller to only run the pump when the immersion has reached temperature, probably just use a timer or read a temp sensor to start with and progress from there.
Looking a the small test I ran this evening the shower exit point dropped from 44 deg C to 34 Deg C in just 6 mins, so my thoughts are that the immersion should soon switch back on (weather permitting).
Thanks guys for your input.
Re Dave
Re: de-stratification setup installed, help / advice required
Dave, I see that your using a DC brushless motor driven pump (of which I know little about!). But I thought that you would need a driver board for the motor, which would also enable motor speed reduction, or is it built into the pump itself? What was the speed controller you fitted, or was it just a variable voltage power supply?
Paul
Re: de-stratification setup installed, help / advice required
Hello Dave,
Does this mean that as the water temperature at the bottom of the tank rises then cavitation may re occur?
The hotter the water is, the easier it will be for cavitation to occur. It didn't help that my dump load was a 5500W immersion element.
is it that pressure is better now the pump is that way around? Short answer, yes.
Hi Paul,
I would expect though that by fitting a restricter valve in the pump output pipe would lessen the pressure difference between the pump input and output (because system water pressure will have greater chance of replacing the water drawn into the pump), thereby reducing cavitation - is this your understanding Bill?
It will reduce the flow but the outlet pressure will increase. e.g. your thumb partially blocking the end of a garden hose.
However, the lower his pump inlet is, compared to the water level in the tank, the greater the pressure at the pump inlet will be. The higher the inlet pressure, the less the likelihood of cavitation. And, he can fit the restrictor, if needed.
I ran the shower and no water was draw up through the de-strat pump, I believe its because new cold water is being fed into the bottom of the tank to replace the water being used by the shower, on the grounds that "water out" must equal "water in" then there is no reason it should take water thorough the smaller pipe.
That - and a behavior often attributed to electrical/electronic circuits - the path of least resistance.
Sounds like you've got it solved, Dave.
Re: de-stratification setup installed, help / advice required
Hi Paul
At present I am just running it from a variable power supply until I get the speed right.
FYI had a very successful day today, left the wife in charge of the pump manual on / off control. I place a lamp on either side on the immersion thermostat switch, instructed her that when the stat opens (lamp goes out) turn the pump on until the lamp comes back on. Running the pump at 9V it only took 4 min to drop the top of the tank temperature enough for the stat to re-close, as the day went on the pump had to run slightly longer as the bottom of the tank water was getting warmer and therefor having less effect on the top temperature. At the end of the day I have a full tank.

Yes Bill looks like its now ok, many thanks for your time in responding.
I am in electronics, hardware & software I am good at plumbing but don't know much about the theory of water & pumps etc. so its always nice when you have a project like this to lean new things.

Hey, don't feel bad about that. I'm an Electronics Tech myself. i.e software isn't my bailiwick, but I manage to get by. Now give me a Doppler Weather Radar, or an Airport Surveillance Radar to repair, and I'm right at home!
Good to hear it's workin' for ya.

Re: de-stratification setup installed, help / advice required
Chaps,
Comments on the above thread
1 There is not enough energy in the pump to cause cavitation of water. All water contains air in solution which comes out with heating. That is why all water systems have a vent somewhere.
2 In pump cold to hot to save thermal stresses on the little 12V pump. I pump cold into the very top of the HW tank with a tee joint on the HW take off pipe. The horizontal one in Dave's diagram above
3 I have ntroduced a slight upward gradient on the pipe. The the air goes up into the vertical vent pipe (the red one on the diag above) I can here it gurgling every now and again.
4 Clealry I'm going to get cold water in the hot line, so I inhibit destratification whenever hot water is drawn off. I have a small axial flow turbine in the pipe with a Hall Effect (magnetic) sensor. This is the only way I could get a reliable inhibitor signal. I did look at reed switches in power shower pumps but these need to me mounted vertically. My turbine meant a bit more plumbing but it works well and has an effective range of 160 revs/sec when a bath tap is opened. This is a good range to work with if you want to integrate the pulse and calculate volume used. I will be billing my daughter for her water usage.
5 To save destratifying on dull days (or as the sun goes down) I only destrat if PV is > 0.5 kW
6 I calculate the energy stored in the tank to be about 9kWh. If I get to this level I stop destratifying
7 My TTop (tank top) temp is 60C anf the immersion heater element is set at 63C (Note the latest Regs call for twin contact thermostats now)
Here is the salient sections of my code so you can see what variables I have settled on and the control logic
#define revspersecSet 5 //turbine rps threshold for destratification inhibition
#define inhibittimeSet 600 //seconds delay between each destrat. Do not have too many successive destrats
#define tempTopSet 60 //60 Destrat start temp. Note tank thermostat set at 63C on 15 Feb 2016
#define tempTopmin 49 //49 destrat if temp top falls below this value, the minimum for a shower, note 3 deg overshoot
#define tDiffSetHi 15 //15 required for destrat to START
#define tDiffSetLo 10 //10 required to destrat to STOP
#define kWgenSet 0.5 //kW before destrat starts
#define pumpPWM 150 // 0 - 255 PWM factor to control speed of pump this is based on 12V DC
#define energyMax 9.0 //TTop of 63 & TBot 58 = 8.89 (16 Feb 2016) after forced destratification
Here is the control logic. Schoolboy programming I know, but it works and I can understanding 6 months later!
if ((inhibittime>inhibittimeSet)&&(kWgen>kWgenSet)&&(Energy<energyMax)&&(tempTop>=tempTopSet)&&(tDiff>tDiffSetHi)){PumpLatch=HIGH;} // if conditions met,set the latch
if (PumpLatch==HIGH){analogWrite(Pump,pumpPWM);} else {analogWrite(Pump,0);} //Pump PWM = N / 255
if ((tDiff<tDiffSetLo)||(tempTop<tempTopmin)||(revspersec>revspersecSet)){PumpLatch = LOW;} // drop the latch
if (PumpLatch==LOW){analogWrite(Pump,0);} // If the latch is dropped, turn the pump off
I still intend to write all this up one day. In the meantime ask if you want help.

1 There is not enough energy in the pump to cause cavitation of water. All water contains air in solution which comes out with heating. That is why all water systems have a vent somewhere.
According to this, possible evaporation - and cavitation - increases dramatically with water temperature.
That being the case, even a small pump can cause heated water to "boil" hence, causing cavitation.
Also on the same page: Cavitation can be avoided by locating components to the coldest part of systems. Example - it is common to locate pumps and modulating valves in heating systems in the "cold" return lines before heaters and heat exchangers.
Re: de-stratification setup installed, help / advice required
Chaps
The original post said he had air in the pump. He needs to prove to himself that his design allows for the venting of the inevitable air that has come out of solution when water is heated. I believe cavitation is unlikely and the symptoms he describes can be explained, initially, by trapped air that has come out of solution. On a good day as my tank destratifies down to a temp difference of < 20 C top to bottom, I always get a small gurgle when the pump starts. Sometimes I can hear the air bubbles passing up the vent pipe. Destratification is going to drive even more air out of solution than if left static.
That is why a slight upward gradient is essential on the top draw-off pipe if you want to use the original vent system
Dave's tapping off below the top of the tank misses the hottest water at the top of the tank . This lower tapping is often there to give a secondary simultaneous HW feed to upstairs bathrooms. He would be better going into the very top pipe. He may have done so by now.
You will find that gravity fed open vented hot water systems although all the same in principle sometimes have variances based on the preferences of the designer (or indeed the plumber depending on what was in his bag that Friday afternoon) It is difficult to give general advice on a forum like this. It is more a case of understanding and agreeing the principles and sharing experiences.
Depending on your particular installation also incorporate a Surrey Flange into the design to encourage the venting of air. This is useful for those that insist on pumping from the hot. However there are many reasons why pumping from cold to hot is much preferred.
Also, insulation is really important and has a marked effect on storage. I have packed my tank with multiple layers of loft insulation and only get a 6C Ttop loss overnight. My loft insulation has tended to break down over many heating cycles so always wear a face mask. I have found that old pillows are good to cover the areas where you need frequent access for maintenance.
SAFETY. Remember we are skiiing off piste here and doing things that the original design can cope with, but did not anticipate. Please make sure you have inspected your venting system, fitted the latest immersion thermostats (with twin contacts) Got some thermostatic mixers on showers and maybe warning signs on HW taps. Keep an eye on any power shower pumps as these don't like > 60C. Its great fun to try and capture all that free energy, but me and my pals have actually REDUCED our top settings to protect people and equipment
Finally. I use the 3 Dallas (Maxim) 18B20 one wire temp sensors at top , middle and bottom of tank. Although more costly I like having a digital output and not having to smooth signals to and from an analog sensor. I have epoxied these on a pipe of copper plate which is itself then epoxied onto the tank. Try and keep the bottom one away from the cold water inlet as if too close this will give non-representative low readings and excessive destatification.
With these 3 sensors you can use this algorithm to give an approximation to the energy stored in the tank.
/* Start of destratification details
The energy required to raise the temperature of water by 1 C is 4.1813 joules per gram.
Assuming tank is 170 litres = 170 kg and the input water is 15C
3.6MJ = 1 kWh
Take average of the temperatures, take off the 15C for incoming water temp (lowest possible) X volume in tank in litres X specific heat convert to kWh
*/
Energy = ((((tempTop+tempMid+tempBot)/3)-15)*170000*4.183)/3.6/1000000; // Energy calc in kWh
Energycap = (Energy/energyMax)*100; // Calculating the energy stored in the tank as a percentage of a maximum in kWh.
.... at least it looks good on the display and gives a good number for my daughter's hot water bill :))
More seriously though, sets a limit on the stored energy so you know when enough is enough. I call it a day at 9 kWh
(note all my posts refer to the traditional gravity fed open vented DHW systems not the more recent pressurised systems)

We have chosen to include these reports to help document the real world use of inhalants, but their inclusion is not intended to imply that they are anything but dangerous.]
I was 13 when I first tried huffing gasoline. I heard about it in school from a motivational speaker, though she must not have been very good, considering I had a major addiction to gasoline for 5 or 6 months, which I now regret. Me and my friend decided to try it at my house, we had already taken speed, and marijuana a mere week before. So we went into my garage and took a 2 liter bottle and filled it about 1/10 full which was more than necessary.
We never thought it was that addicting because we've never heard about that. He was a little scared though so I went first. I took about 10 deep inhalations and everything went out of focus then right back in. I kept hearing this buzzing. I fell in love with that sound. And then everything started to echo, and I thought I was going crazy. My friend started to take some and we started laughing. Everything sounded so clear and loud and my ears were extremely sensitive and I felt like I had no control over myself, he started to scream and I couldn't handle that and I freaked out and tried to punch him but my coordination was so off that I fell and we started laughing after about 2 minutes our buzz was over and he left but he was coming back over later to take a walk and would bring some gas .
The rest of the day I was in a daze and I didn't really care about anything and I found my self dazing for 2 or 3 hours at a time but he called at about 2:30 in the morning and we started to walk to a campground and inhale gas on this cliff we always hang out on (very stupid.) So we packed a 2 liter bottle with the same amounts of gas and started walking for about a mile. We weren't even halfway there but we decided to take a little in the middle of the road in the country but before we started to inhale we heard people yelling our names. We turned around and it was these 7th grade girls (who were very cute.) We told them what we were going to do so they came along to watch the show. I went first again and started inhaling deep for about 30 times and it hit me very hard. I heard the buzzing but I felt numb and my head was throbbing everyone was yelling at me if I was ok but I couldn't say anything and they echoed.
They told me to sit down but I fell backwards and landed on my head but couldn't feel it. They all sat down next to me but I couldn't understand them. Suddenly I turned blind and started twitching but then I passed out and I had an odd but scary hallucination. I saw my face and it was in black and white, but it started blinking red over it and the buzzing sound was synchronized with the blinking and it kept getting more intense with louder faster buzzing and blinking and it made me shake. It reached its peak then it sounded like beeping from a microwave and I suddenly woke up and I was bleeding and one of the girls were crying while my friend was saying 'trippy man.'
My experience was so eerie and horrible I don't know why I kept doing it. The addiction was so strong. One night I looked up the effects of inhaling gasoline and I stopped right then, but only after I haven't turned in an assignment in school for nearly 3 months and my mind was fried, I couldn't even skateboard which was what I lived for. I just didn't care, I spaced out all day and slept. I'm now 15 and I realized my brain isn't 'fried' and I seem back to my normal self but it took me about 2 years.  I finally recovered.  Looking back now I can't imagine how I didn't die or fall into a coma. The worst thatís happened to me is passing out for 4 hours.

Throughout my life, I have traveled to over six different countries and explored most of the United States. When I was younger, my dad would always talk about his adventures when he was younger. Hearing his stories instilled a passion for traveling in me. I think the most amazing place that I have visited thus far would be Paris. The atmosphere, culture, and community were so incredible. Even though I have visited a variety of different places, I would love to travel to Japan with my best friend (she was born in Japan).
Summer 2019
Last year I completed an attachment course at Marist where I was able to travel to Paris for two weeks.
Summer 2019
After completing my summer research project at Marist, I went to Prague for a week with my family.
Summer 2018
My family decided to travel to London for our first European vacation.
Summer 2016
My family stayed in a treehouse when we vistied Costa Rica, which was an incredible experience.

MCMC setup¶
The Markov chain Monte Carlo algorithm implemented in the emcee
package is used. This reduces the effort of implementing MCMC to defining the prior and likelihood functions, and providing some basic setup parameters for emcee.
The Seriously Kick-Ass MCMC emcee
package is a pure python implementation of the Goodman & Weare’s Affine Invariant Markov chain Monte Carlo (MCMC) Ensemble sampler. The emcee package can be obtained here, and it is described in Foreman-Mackey et al. 2012.
Parameters & Observables¶
The model parameters () that are used to predict the observations ( y and yerr ) are initial mass, initial metalicity and age (). These parameters are defined as follows:
Parameter Name Unit initial mass Mass_init initial metalicity M_H_init dex age log_Age
The observable parameters are effective temperature, luminosity, surface gravity, radius and metalicity. The observed metalicity can be different from the initial metalicity due to diffusion and mixing processes during the lifetime of the star. All evolution models shipped with emcmass use the same names and units for the observables, they are defined as follows:
Observable Name Unit effective temperature log_Teff luminosity log_L surface gravity log_g in cgs radius log_R metalicity M_H [M/H]
Priors¶
emcmass uses a flat prior for all model parameters (). The log-prior function is defined as returning 0 if all parameters are within their limits and returning if any parameter is outside its limit.
This prior is defined in the emcmass.emcmass.lnprior()
function. It takes as arguments the model parameters (), and the limits on the parameters as a list of tuples. In the following example the masses are limited between 0.1 and 2.0 Msol, metalicity between -1 and 0.25 and age between 1 Myr and 1 Gyr:
>>> limits = [(0.1, 2.0), (-1, 0.25), (6.0, 9.0)]
>>> lnprior([0.91, -0.125, 6.67], limits)
0
>>> lnprior([2.31, -0.125, 6.67], limits)
-inf
Likelihood function¶
The likelihood of observing observables y for a given model is defined as , where the chi squared function is calculated as:
where are the theoretical values for the given model parameters .
The likelihood function is defined in the emcmass.emcmass.lnlike()
function. Its arguments are the model parameters , the observables y and the errors on the observables yerr. It will call the emcmass.models.interpolate()
function to determine the theoretical values for the observables.
Markov chain¶
To create the Markov chains with the probability distribution , a Metropolis-Hastings jump probability distribution is used. This is also the standard setup in emcee. It is defined as follows. A trial point in the vicinity of the current model parameters is picked. If any of the model parameters are outside the valid range, the point is imediatly rejected. This is achieved by the prior function returning if the model parameters are outside their limits. Otherwise, the probability of accepting the new point is given as:
Meaning that if the likelihood of the new model is higher then the current one it is always accepted, but if it is lower the probability of accepting it depends on the fraction of the likelihoods.

--- layout: post tags: [AutoFixture] date: 2009-09-02 20:21:13 UTC title: "AutoFixture .8.5 Released" --- {% include JB/setup %}
It gives me great pleasure to announce that I have just release version .8.5 of AutoFixture. It is a minor release (hence the numbering) that mainly contains a lot of convenience overloads to already existing methods. There is also a single bug fix.
There are two breaking changes (documented on the release page), but they are minor and I do not expect them to cause problems. Only one of these even remotely affects any part of the API I have already discussed here, and that relates to what kind of exception is being thrown when AutoFixture is unable to create an instance of the requested type.
Please go ahead and download it and use it heavily :) As always, comments and questions are welcome.


Deployment on UMich Space
Now that you are happy with your local website, it is time to deploy it on the internet. Here is the methodology for UMich personal space hosting.
See Web Hosting Tutorial from ITS for more details.
A note on the Academic theme
To ensure links consistency within your website you need to tell Hugo what will be your base URL. In the case of GitHub hosting, change the following line in config/_default/config.toml
:
baseurl = "http://www-personal.umich.edu/~uniqname/"
Run hugo
to make your changes effective.
Prerequisites
First, you will need access to the MFile system. There, ensure you have access to your Public/html/
folder which is where we will dump our website.
You may need to use the make-website tool.
Local version control
While version control is not necessary for this type of hosting, I highly recommend you do it locally:
git add -all
git commit -m 'First deploy'
Deployment with SCP
The deployment to your personal space can be done in one command line (should work on any platform, Windows users may require PuTTY):
scp -r <path-to-local-website>/public/. uniqname@login.itd.umich.edu:Public/html/
You should be prompted to enter your password. SCP (Secure Copy Protocol) can only copy files to and from a remote server. It is sufficient to push your website, but you cannot remove files using that protocol. This line basically copies everything from <path-to-local-website>/public/
(recursively with the -r
option) to your personal space uniqname@login.itd.umich.edu:Public/html/
which is where websites are hosted.
SFTP and SFTP With a GUI
sftp
(Secure File Transfer Protocol) offer an interactive session and is therefore more flexible than SCP (see thig guide).
Open a terminal in the public
folder of your website (or the one where Hugo produces the html
files). Connection to the remote server is done via
sftp<EMAIL_ADDRESS>You should be prompted to enter your password. You can navigate your personal space usin ls
and cd
as usual. Move to Public/html
and push all the files of public
:
sftp> cd Public/html/
sftp> put -r *
The same can be done using a FTP client GUI (e.g. WinSCP or FileZilla). The server is called
sftp.itd.umich.edu
with port 22. You should need to input your username and password at some point.
Viewing your website
Your new website will be available at
http://www-personal.umich.edu/~uniqname/
which is also available by symply typing
umich.edu/~uniqname/
If you are creating a website for some organization, consider getting some space for your organization instead of using your own space: check this tutorial (Special services section).

People interact with their phones very differently than they do with their PCs, and I think that when you design from the ground up with mobile in mind, you create a very different product than going the other way.
Kevin Systrom (1984–) American Businessman
Design to Web
What is your site’s primary purpose?
There are two purposes, but they are intertwined:
To help me learn the web design and development process.
To showcase my work and skills.
Who is your target audience?
Teachers at EDA
Fellow students at EDA
Friends and family
Future employers
How do you want site visitors to interact with your site? What experience would you like them to have?
Visitors will interact with the site by scrolling and using built-in navigation. This means it has to be as easy to use in mobile-view as for tablets or desktops. I'd like their experience to be one of enjoying the site and have the process of using the site be transparent (that is: everything is intuitive).
How will you build your site to support your desired user experience?
It needs to be responsive and look good. For me, things that are off-putting include spelling mistakes or an amateurish appearance. I know that EDA emphasises process over product. I will follow the development processes, but I will still try to ensure that the finished result is something that I'm proud of.
Aspects of Design
What is a responsive site? Why is responsiveness important?
Responsive websites adapt to the size of the screen (and therefore browser window) used to view them. Responsiveness is important because an increasing use of the Internet is via mobile devices which have smaller screens: these users have to be catered for. It is also important for the developer because only one website needs to be created, not multiple versions for different devices.
What is mobile-first design, and why is it important?
Responsiveness is really just a technical solution to scaling down wide webpages so they fit on narrower screens. In contrast, mobile-first design is a strategy where a website is produced for small screens and then scaled up for larger devices. By focusing on optimising mobile users' experiences, designers need to focus on important content which can be enhanced for Internet users with larger screens.
What are frameworks, and what are their pros and cons?
A front-end framework is prewritten HTML, CSS, and JavaScript files used develop websites. Often, frameworks (like Bootstrap or Skeleton) contain code to manage known problems like browser quirks. So frameworks save developers time and help ensure consistency. However, frameworks can be complex and may have steep learning curves. Also, websites built with frameworks may contain unused code, resulting in larger files which are slower to load.
What is a wireframe and why do we use it?
A website wireframe is a plan showing the structures of webpages. Wireframes attempt to show how content like text, images and navigation are to be arranged, without focusing on formatting or visual appearance. Wireframes allow clients and developers to visualise a site's structure and how it will function. They also speed up the development process as misunderstandings are minimised and stakeholders have an opportunity to critique designs before coding starts.

What aspects of your wireframes were difficult to implement? Why?
I have used BootStrap before, so I'm not a complete novice with CSS frameworks. I did however, have problems getting my design to work properly. Then I read the following line in the documentation: <!-- columns should be the immediate child of a .row --> What I had done was to put in semantic tags; changing them back into <div> tags fixed these issues. Every EDA student having problems with Skeleton needs read that comment out loud, ten times.


Turkey says it bought Russian S-400s to use them, not put them aside
by ReutersANKARA — Turkey bought S-400 missile defense systems from Russia to use them, not put them aside, the head of the Turkish Defence Industry Directorate said on Saturday, days after talks between President Tayyip Erdogan and U.S. President Donald Trump.
In an interview with broadcaster CNN Turk, Ismail Demir said it was not logical for any country to purchase such systems only to put them aside, but added that Turkish and U.S. officials would aim to tackle the issue. He also said that no Russian personnel would come to Turkey to operate the S-400s.
Erdogan and Trump held talks in Washington on Wednesday to overcome mounting differences between the NATO allies, ranging from sanctions threats over Turkey’s purchase of S-400s to Syria policy. Washington says the S-400s pose a threat to its F-35 jets and has suspended Turkey’s involvement in the program. (Reporting by Tuvan Gumrukcu; Editing by Catherine Evans)

Brex dominate Albirex early to win on the road
by Ed OdevenThe Utsunomiya Brex used a 21-0 run in the first quarter to seize control of their game against the Niigata Albirex BB on Sunday.
The big scoring spurt started with a Jeff Gibbs inside bucket with 6:08 to play in the quarter. It ended with Takanori Tahara’s in-the-paint jumper, courtesy of a Shuhei Kitagawa assist, that put the Brex ahead 32-7.
The Albirex trailed 34-12 after the opening stanza and lost their second game of the weekend, falling 85-76 in Nagaoka, Niigata Prefecture.
Makoto Hiejima, who nailed four 3-pointers, led Utsunomiya (12-4) with 17, while Gibbs added 13 points and 11 rebounds, Kosuke Takeuchi and Hironori Watanabe both had 12 points and Seiji Ikaruga 10. Do-it-all forward Ryan Rossiter chipped in with eight points, nine rebounds and five assists.
Nick Perkins had 27 points, Lamont Hamilton added 21 and Shunpei Ishii scored 13 for Niigata (5-11), with Kenta Morii handing out nine assists.
“Our start was a violent defense that could confuse our opponent’s pace,” Hiejima told reporters after the game.

In this project, you'll use generative adversarial networks to generate new images of faces.
You'll be using two datasets in this project:
Since the celebA dataset is complex and you're doing GANs in a project for the first time, we want you to test your neural network on MNIST before CelebA. Running the GANs on MNIST will allow you to see how well your model trains sooner.
If you're using FloydHub, set data_dir
to "/input" and use the FloydHub data ID "R5KrjnANiKVhLWAkpXhNBe".

Probably the most popular startup book in recent history, The Hard Thing about Hard Things was written by Ben Horowitz and contains stories and lessons from his many years leading software companies from Loudcloud to Netscape. The lessons contained in the book span all parts of the lattice.
The book focuses on managing yourself, managing people, and some very specific parts of the application domain. There’s a very specific tip to take care of people first, products next and then profits.
In the domain of managing self, the book talks about the following concepts:
- Keeping a clear head, embracing the struggle of being an entrepreneur
- Enjoying the work
- Face the hard decisions head on
The lessons about self management are some of the best parts of the book. From experience Ben talks about the struggles of being a CEO and how managing oneself is the first (and many times, most important) part of the job.
In the domain of managing individuals, the book talks about the following concepts:
- Tell things like it is
- Rephrase the worst case scenario
- Some very specific hiring tips - like hiring for strength vs. lack of weakness,
In the domain of managing teams, the book talks about:
- How large Organisations are slowed down by single people
- Minimise Politics by hiring for the right type of ambition, maintaining strict policy on org design, promoting based on performance, and ensuring 1:1’s are held. Ben is a subscriber to the Andy Grove school of thought so OKR’s make their way into The Hard Things as well.
In the domain of products and markets, the Hard Thing speaks of:
- Good Product Managers vs. Bad Product Managers, a guide that continues to be relevant in the world of product management today.
- Wartime CEO (vs Peacetime CEO), a mode of operating (defined by competitive market position) that changes all the rules of operation
The Hard Things doesn’t fit neatly in the lattice, but it does fit. All the lessons fall within one of the domains. It takes a very unique perspective and offers some real, raw leadership advice.


URGENT BUSINESS PROPOSAL Goodday Sir/Madam I am a member of Independent Committee of Eminent Persons (ICEP), Switzerland. ICEP is charged with the responsibility of finding bank accounts in Switzerland belonging to non-Swiss indigenes, which have remained dormant since World War II. It may interest you to know that in July of 1997, the Swiss Banker's Association published a list of dormant accounts originally opened by non-Swiss citizens. These accounts had been dormant since the end of World War II (May 9, 1945). Most belonged to Holocaust victims. The continuing efforts of the Independent Committee of Eminent Persons (ICEP) have since resulted in the discovery of additional dormant accounts - 54,000 in December, 1999. The published lists contain all types of dormant accounts, including interest-bearing savings accounts, securities accounts, safe deposit boxes, custody accounts, and non-interest-bearing transaction accounts. Numbered accounts are also included. Interest is paid on accounts that were interest bearing when established. The Claims Resolution Tribunal (CRT) handles processing of all claims on accounts due non-Swiss citizens. A dormant account of ORDNER ADELE with a credit balance of 20,000,000 US dollar plus accumulated interest was discovered by me. The beneficiary was murdered during the holocaust era, leaving no WILL and no possible records for trace of heirs. The Claims Resolution Tribunal has been mandated to report all unclaimed funds for permanent closure of accounts and transfer of existing credit balance into the treasury of Switzerland government as provided by the law for management of assets of deceased beneficiaries who died interstate (living no wills). Being a top executive at ICEP, I have all secret details and necessary contacts for claim of the funds without any hitch.we can share the funds and use in investment of our choice. Due to the sensitive nature of my job, I need a foreigner to HELP claim the funds. All that is required is for you to provide me with your details for processing of the necessary legal and administrative claim documents for transfer of the funds to you. Kindly provide me with your full name, address,date of birth and telephone/fax. We will pay all required fees to ensure that the fund is transferred to a secure, numbered account in your name in Spain, of which you will be capable of accessing the funds gradually and transferring to your country and other banks of choice in the world. My share will be 60 percent and your share is 40 per cent of the total amount. You can find additional information about unclaimed funds through the internet at the following websites: www.swissbankclaims.com http://www.cnn.com/WORLD/europe/9902/09/germany.holocaust/ www.avotaynu.com www.icheic.org www.livingheirs.com www.wiesenthal.com I find myself priviledged to have this information and this may be a great opportunity for a life time of success without risks. Thank you for your prompt response. You can write me in German if you wish Your´s Sincerely Alan Rodriguez Please reply me under the following e- mail address<EMAIL_ADDRESS>PS, please delete this letter if you are not interested


10.1. Installing GeoMesa Bigtable¶
10.1.1. Building from Source¶
GeoMesa BigTable must be built from source. For more information refer
to Building from Source in the developer manual, or to the
README.md
file in the the source distribution. Build using using the
bigtable
Maven profile:
$ mvn clean install -Pbigtable
The Bigtable-specific code will be found in the geomesa-hbase/geomesa-bigtable-*
directories of the source distribution.
More information about developing with GeoMesa may be found in the Developer Manual.
10.1.2. Installing GeoMesa Bigtable in GeoServer¶
The Bigtable GeoServer plugin is not bundled by default in the GeoMesa binary distribution and should be built from source.
After building, extract geomesa-hbase/geomesa-bigtable-gs-plugin/target/geomesa-bigtable-gs-plugin_2.11-$VERSION-install.tar.gz
into GeoServer’s WEB-INF/lib
directory. This distribution does not include HBase or Hadoop JARs; the following JARs
should be copied into GeoServer’s WEB-INF/lib
directory:
- commons-configuration-1.6.jar
- hadoop-annotations-2.5.2.jar
- hadoop-auth-2.5.2.jar
- hadoop-client-2.5.2.jar
- hadoop-common-2.5.2.jar
- hadoop-hdfs-2.5.2.jar
- hbase-annotations-1.1.2.jar
- hbase-client-1.2.3.jar
- hbase-common-1.2.3.jar
- hbase-hadoop2-compat-1.1.2.jar
- hbase-hadoop-compat-1.1.2.jar
- hbase-prefix-tree-1.1.2.jar
- hbase-procedure-1.1.2.jar
- hbase-protocol-1.2.3.jar
- hbase-server-1.1.2.jar
(Note the versions may vary depending on your installation.)
The Bigtable data store requires the configuration file hbase-site.xml
to be on the classpath. This can
be accomplished by placing the file in geoserver/WEB-INF/classes
(you should make the directory if it
doesn’t exist). For more information, see Connecting to Cloud Bigtable.
Restart GeoServer after the JARs are installed.


LEFT BEHIND: THE MOVIE A film review by Steve Rhodes Copyright 2001 Steve Rhodes RATING (0 TO ****): **
The plot for Victor Sarin's LEFT BEHIND: THE MOVIE involves nothing less than world peace, world government, world currency and the world's food supply. And these are just the minor issues.
As it opens, GNN reporter Buck Williams (Kirk Cameron) breaks the story of unknown forces from all over the world staging massive air-strikes on Israel, but the confusing script quickly discards this subplot. Based on the first of a series of best selling novels by Jerry B. Jenkins and Tim LaHaye, the story is really about the end of the world as we know it after the chosen few, actually the chosen 142 million -- plus or minus a few souls -- have ascended into heaven.
Neither as bad you might fear nor as good as you might hope -- see THE RAPTURE for a successful picture with similar themes -- LEFT BEHIND: THE MOVIE alternately intrigues and baffles the viewers. Sometimes watching it makes you think that you need a secret decoder ring to be able to grasp the intricacies of the confusing plot. (Whether detailed knowledge of the Bible would clear up many of the movie's mysteries is debatable.)
After the potential world war starts in Israel, the real excitement begins. There is panic in the streets and in the air after people disappear en masse. All of the young children and many adults vanish in an instant, leaving their clothes and other worldly possessions behind.  In the air, passengers on Buck's flight disappear, causing pandemonium.
When people realize what is happening, some of them return to their religious roots to look for an answer and for consolation.
"If you don't put your faith in God, you will be deceived," Rayford Steele (Brad Johnson), a repentant adulterer, warns Buck. This proves to be prescient advice, when Buck has to deal with nothing less than the Antichrist himself.
"You get so wrapped up in life that one day you wake up and realize you've missed it," Rayford tells his daughter Chloe (Janaya Stephens). This painfully true sentiment is like much of the movie, which is overacted but true to its principles. The story has much to say. It is a shame that it couldn't have done a better job of it.
LEFT BEHIND: THE MOVIE runs 1:35. It is rated PG-13 for violence and would be acceptable for kids around 9 and up.

opening a bank account, checking account
You will probably need to start a bank account for your orchestra pretty early on, before you find yourself having to make a lot of monetary transactions. You should shop around the local banks to find one that offers free business checking accounts (different from a personal account) for nonprofits and community organizations. Some will offer the free account even if you have not yet obtained your official nonprofit status. Also see if you can get a debit card with the account; it comes in handy if you need to make online purchases.
Your bank will tell you what specific documents are required, but it will likely include the following:
The officers you want to be account signatories will have to show up together in person with their identification materials to fill out paperwork. If your meeting minutes don't explicitly state which officers will be account signatories, they might just allow you to write it in and sign it, which is what the RCO did.
The RCO decided that the President, Vice-President, and Treasurer should all be legal signatories with access to the bank account. One of our officers had had a bad experience in the past with another nonprofit in which the Treasurer was the only one with access to the account and banking records. The Treasurer failed to fill out some required IRS forms and then sort of disappeared, leaving the organization with an account they couldn't close and IRS paperwork they couldn't complete. We consequently decided that redundancy was a good thing.
You can open your bank account before obtaining your official 501(c)(3) nonprofit status. The account will be taxable until you obtain your nonprofit status, but unless you expect to be bringing in significant amounts of money, you will not have to pay very much tax.
At the time of the RCO's first concert, we did not yet have a bank account. We collected donations at the door, and the Redlands High School Band Boosters very kindly allowed us to park our cash temporarily with them until we could establish our own account about two months later. When we got our account set up, they just wrote us a check for the amount we had collected. The RCO was ready to open an account in December, but we waited until January to avoid having any income during the previous tax year. We then got our nonprofit status later the same year.
