![]() ![]() Because of the war, construction did not begin until 1920. In 1916 Congress appropriated $1 million for the construction of a naval research lab, which would be built near the U.S. there should be a pattern shop, foundries for brass, cast iron and steel, and machine shops for large and small work.” As Edison told the New York Times, “The laboratory should be of complete equipment to enable working models to be made and tested. Modelled after his own West Orange research facility, Edison’s proposal called for a well-equipped laboratory capable of producing new invention rapidly. Edison recommended that the Allies change their shipping schedules to avoid German submarines.Įdison encouraged the Navy to establish a permanent research laboratory. and its Allies were using prewar shipping routes, which made it easier for enemy submarines to target ships, and that many ships were passing through danger zones during daylight. At the conclusion of this research, Edison discovered that the U.S. From October 1917 to January 1918 he used an office in the State, War and Navy Building near the White House (now called the Eisenhower Executive Office Building) to collect data on Allied shipping losses. In the fall of 1917 Edison moved his war research to Washington, D.C. Peter Cooper Hewitt experimented on helicopters, while Frank Sprague developed depth charges, underwater fuses, and armor-piercing shells. Hudson Maxim invented improved contact mines and torpedo fuel. Elmer Sperry developed a number of improvements for airplanes and submarines, including a device to detect hydrogen in submarines, improved steel airplane propellers, and remote-control devices for aerial bombs. The technical research conducted by individual board members was more consequential. None of these ideas, however, were practical. Other ideas for camouflage and smoke reduction (to reduce the visibility of ships) were also tested. This committee received thousands of suggestions from the public for shields and nets to protect surface vessels from submarines. In February 1917, the Naval Consulting Board created a Special Problems Committee to address the issue of protecting ships from surface attack. The orientator, a simulated pilot’s seat mounted on gimbals, allowed instructors to simulate aircraft motion for pilot trainees. Of these submissions, only 110 were referred to one of the subcommittees for evaluation, while only one – the Ruggles Orientator – was produced during the war. The board received approximately 11,000 suggestions, most dealing with the submarine. These subcommittees evaluated invention proposals submitted by the public. At its first meeting on Octothe Naval Consulting Board quickly adopted operating rules and created fifteen subcommittees organized by subject, including submarines, ordnance and explosives, mines and torpedoes and ship construction. ![]() ![]() These packets can be of Varible length but would always have the same Information and then be able to break it apart when I recieve it at the otherĮnd.

I have done some reading and found that I think I need to serialize the Services framework is integrated into the VS.NET IDE so it's easy to create web services (for sending objects and data over the You have your choice of serializers for SOAP XML or Binary depending on the context of your application and it's data. Remoting will allow you to serialize and deserialize objects and pass them through registered channels via TCP or HTTP connections. That would be a more appropriate place then a C# thread. There is a remoting thread you can post questions on. Search around Google or MSDN and you'll find a ton of topics.

The code should switch a LED on and off and be able to tell me the status on the LED(whether its on or off) Perhaps a description of what your code is intended to do will help. Im not quite sure if i understand this right? because when i send a tcp packet to the arduino i cant get it to do anything. It will wait until some data (a request from the outside) is available(), then a Client will be created on the spot to read the incoming message, and finally the server will send the response to the outside client and close the connection. From your code I think that the Arduino will work in the role of the server (EthernetServer). The main difference is that TCP requires the establishment of a connection, so there are two different behaviors: the client requests the connection, while the server waits for incoming connection requests. The answer it's the same Ethernet library you are already using (there's no specific "EthernetTcp" library, just Ethernet).

Studies should be conducted far away from any background EMF contamination. Such facilities are full of equipment which generates electromagnetic fields, from wiring to imaging equipment. But if they were conducted in hospitals or clinics, the results are problematic. I have no way to determine whether these studies were conducted in isolation from background EMF interference this was not discussed in the abstracts or conclusions. These studies both found that participants who claim EMF hypersensitivity were unable to discern when EMF radiation was present and when it was not. The 2005 review concluded, “Electromagnetic hypersensitivity is unrelated to the presence of EMF, although more research into this phenomenon is required’” (2) The 2008 study found “no evidence that EMF hypersensitive individuals could detect presence or absence of RF-EMF better than other persons.” (3) Two systematic reviews of EMF hypersensitivity were performed in 20. The Canadian Human Rights Commission also considers EMF hypersensitivity an environmental sensitivity and a disability. In Sweden employers and building owners are expected to rectify EMF problems, and sufferers are entitled to disability benefits. Self-reported rates of EMF hypersensitivity vary from 1.5% in Sweden, where the condition is officially recognized as a disability, to 3% in Calfornia, 4% in the UK, and 5% in Switzerland. External electromagnetic fields can interfere with these signals. Neurons (nerve cells) and muscle cells pass information from cell to cell using small electrical charges, or microvoltages. ![]() The frequencies of these fields vary by the source, but most fall within the GHz (gigahertz) ranges employed by cell phones and Wi-Fi systems.Ĭells in our bodies generate their own small fields. Here we’ll attempt to make sense of it all.Īnything that uses or transports electricity generates an electromagnetic field, including high voltage power lines, household appliances, radios, televisions, cordless telephones, cell phones and towers, computers, and microwave ovens. Many researchers dismiss it, but several studies show it can affect some people. The scientific world is divided as to whether EMF hypersensitivity is real. But for people who are sensitive to electromagnetic fields (EMF), the effects can include hypersensitivity, tinnitus, and other serious symptoms. For most of us, this may not be a problem. In the modern world we are bombarded with electromagnetic radiation. He is an expert on the condition and a well-known advocate for those with tinnitus. Barry Keate, has lived with tinnitus over 40 years and has published 150+ research articles on numerous aspects of tinnitus. ![]() ![]() While I wasn't quite as shy and quiet as she was in school, I too often felt ignored and invisible, and to be completely honest, I often still do even as an adult.įans of Raina Telgemeier and Victoria Jamieson will love this book as well, and I would also suggest it to fans of the middle grade Dear Dumb Diary, Dork Diaries and Diary of a Wimpy Kid series. This is a great story for all those kids who have a hard time finding their voice and often feel insignificant, and I readily identified with Emmie's character. I don't want to say too much in a review, but in the end it will even make more sense that Katie's perspective is shown in a more cartoon-y fashion. ![]() I really enjoyed this book, and thought it was interesting how the author used a different format and color palette for each characters' perspective while telling the story. (Not being a graphic novel person, I preferred reading the "Emmie" sections, no surprise.) ![]() The colors for Emmie's pages are soft and muted, while Katie's story is told with bright, vibrant colors, further reflecting the differences in their personalities. The passages about Emmie are more like an illustrated chapter book, written in regular prose paragraphs accompanied by doodles to illustrate, while the parts about Katie are told in traditional panels, comic book-style. Not only are the two characters' personalities different, the author presents them in two different illustration styles. These two seem to have nothing in common, until one day something happens that causes their lives to intersect, ultimately helping Emmie to find her voice and become visible. Katie, on the other hand, is pretty, popular, and outgoing. So no one really notices her, and she feels invisible. ![]() She does not talk to other people or speak up in class, and is perfectly ordinary in almost every way, other than having artistic talent. Emmie is very quiet, shy, and introverted. Another great "middle school angst" graphic novel from a debut author! This one is a little bit different from the others.įirst of all, the main character does not somehow stand out as being different from everyone else, nor is she teased, picked on or bullied. ![]() ![]() If the user answers YES, LibreOffice then proceeds with deleting the old version before installing the new one. As one of the first steps in the upgrade process, LibreOffice asks the user if (s)he wants to delete the old version. However, there is no need to explicitly uninstall the old version before installing the new version. The package manager can also be used to uninstall the old LibreOffice version, again taking care of any and all dependencies. The additional benefit of a package manager is that it will resolve and install any and all dependencies. ![]() All a user has to do to install LibreOffice is to use their distro’s Software Center or Software Manager. Most of today’s active distros contain LibreOffice in their default repositories. In the case of LibreOffice, there is no need to complicate one’s life by trying to install it using the esoteric and byzantine CLI commands. There is a time and a place to install programs/packages using the command line – as when installing obscure software from obscure sites.

Winifred gave me some sound advice and helpful tips. Prior to making the video, I touched base with Winifred Whitfield and asked her if she would like to sit in on the video. Oh yes, I did mention there was a surprise in the last video. I like to leave it open for the viewer to interpret. I am not interested in making an image that screams landscape. I add a few lines here and there to help solidify the landscape. ![]() The last video is the longest and I do the least. I find I get subtle textures with flow maps and more aggressive textures with papers. With real watercolors, you can adjust the variant to work with flow maps or paper textures. Papers are key to my techniques, which is obvious in the first two videos. In the second video, I add two more watercolor layers. ![]() I hope you enjoy the first video.Īt the end of the first video, I finished one watercolor layer. OK, I better shut up before I give away the ending. Basically, it is a series of recorded commands that can be played back. A script is the same thing as an action in Photoshop. To make it easier for me, I created a script to do the task. I do this to give me the illusion that I am painting on watercolor paper. In the first video, I show how I like to create a paper texture at the top of the layer stack. Corel Painter 2016, Custom watercolor variants ![]() |
