![]() In addition to EWR’s line of portable weather radar systems, it also provides large, fixed-based weather radars to a wide array of clients including utility companies, oil companies, municipalities, first-alert responders and foreign governments including those of South Korea, Mexico, Indonesia, Myanmar and the United Arab Emirates. The E700 PDR Weather Radar System is in use today by the US Air Force Special Operations Command, the United States Marine Corps for its Meteorological Mobile Facility (METMF) Next Generation (NEXGEN) systems and by the US Air Force for its next generation PDR (Portable Doppler Radar) program. Where other Doppler radars utilize tube transmitters (klystrons, magnetrons, TWTs, etc.) that require frequent maintenance, run at high voltages and are prone to failure in difficult environments such as those found in mobile applications, the E700 PDR uses a long-life solid-state transmitter which is virtually maintenance free and consumes far less power. ![]() Notably, EWR has pioneered the use of solid-state transmitters in weather radar systems. This experience is a key contributing factor in the United States Department of Defense’s decision to make EWR its primary supplier of ground-based weather radar systems. ![]() Since it was founded in 1982, EWR has been an industry leader in portable X-band weather radar solutions.Īdditionally, the company highlighted its long experience with such systems which provides it with a detailed understanding of what it takes to build a radar system that is compact and rugged and can handle the rigors of mobile and rapid deployment in some of the most hostile conditions. Under the contract, EWR will provide contractor logistics support for the Air Force’s 22 currently fielded Portable Doppler Weather Radar Systems (E700XD), as well as 27 newly procured units from a separate contract awarded to EWR earlier this year.ĮWR noted that it has a proud heritage of supplying the United States Department of Defense with weather radar systems. ![]() The new PDR CLS contract has a value of US$21,529,141 and began immediately upon the expiration of the Air Force’s previous CLS contract, also held by EWR. ![]()

The fibonacci appears in the smallest, to the largest objects in nature. The Milky Way’s dust obstructs us from seeing the depth of these filaments or sheets, so we do not yet know the exact shape of these walls. Currently the largest known structures are these walls or filaments of numerous superclusters that are gravitationally bound and separated by large areas of void. Galaxies group together in superclusters and superclusters group together in walls. Spiral galaxies are the most common galaxy shape. The fibonacci as some of the largest structures in the universe. An energy system in the shape of a fibonacci moves with limited losses. The fibonacci spiral appears not only in the perfect nautilus shell,īut in events and objects viewed from a far. Yet you will not see the fibonacci everywhere, as nature has many different methods and shades of survival. The fibonacci also defines how the density of branches increases up a tree trunk, the arrangement of leaves on a stem, and how a pine cone’s scales are arranged. ![]() Fibonacci’s sequence was first introduced to the western world in 1202 by Fibonacci, the sequence had been noted by Indian mathematicians as early as the sixth century. ![]() The Fibonacci sequence is named after Leonardo of Pisa, who was known as Fibonacci (named after, he did not discover). ![]() ![]() ![]() People vote to select a slate of electors, and each elector pledges to cast his or her vote for the candidate who gets the most votes from the people they represent. Unlike members of Congress, the president and vice president are not elected directly by the people every four years, but through the electoral college system. In addition to the president, who is the commander in chief of the armed forces and head of state, the executive branch includes the vice president and the Cabinet the State Department, Defense Department and 13 other executive departments and various other federal agencies, commissions and committees. Executive BranchĪrticle II of the Constitution states that the executive branch, with the president as its head, has the power to enforce or carry out the laws of the nation. Both the veto power and Congress’ ability to override a veto are examples of the system of checks and balances intended by the Constitution to prevent any one branch from gaining too much power. In the case of a regular veto, Congress can override the veto by a two-thirds vote of both houses. Once that happens, the bill goes to the president, who can either sign it into law or reject it using the veto power assigned in the Constitution. In order to pass an act of legislation, both houses must pass the same version of a bill by majority vote. Therefore, while there are 100 senators, there are 435 elected members of the House, plus an additional six non-voting delegates who represent the District of Columbia as well as Puerto Rico and other U.S. While each state gets the same number of senators (two) to represent it, the number of representatives for each state is based on the state’s population. ![]() Members of Congress are elected by the people of the United States. ![]() This legislative power is divided further into the two chambers, or houses, of Congress: the House of Representatives and the Senate.

As the performance worsens a lower mark is granted. ![]() If none of the samples change chromatically, the light source is recognised an Ra of 100. Secondly, eight sample colours are lit by the lamp being studied, and the results are compared with those of a “black body” which has been taken to the same colour temperature. ![]() The chromatic yield indicator (Ra) is a system that has been derived from vision experiments to assess the impact exercised by different light sources on the colour that is perceived of items and surfaces.įirst of all the colour temperature of the light source must be identified. This need varies with the item: generally it is more marked for multi-coloured items and lower in monochrome items. The chromatic yield of light source corresponds to the ability to recognise the colours of an exposed item. This measurement is expressed in Kelvin degrees (K). As the temperature increases, the black body gradually changes from red to orange, to yellow, to white to finally reach white-sky blue. The theoretic principle this measurement is based on is the “radiating black body”. The colour temperature of a light source is based on the principle that an incandescent item changes colour as the temperature increases. For both uniformity must be equal to U0 ≥ 0.10. The standard moreover specifies that a lower illuminance level may be accepted should the above-mentioned level not be complied with due to the dimensions and the complexity of the rooms or to operational factors.įor example, poor mean illuminance values are accepted in case of high ceilings with suspended lighting fixtures located far from the ceiling.įor rooms where visual activities or tasks require luminous surfaces, such as offices, schools and hospitals, the mean illuminance values should be 75lux for walls and > 50 lux for ceilings. The reasons for the introduction of this provision are based upon the fact that both walls and ceiling are included in the observer’s field of view (also called background) and are therefore of the utmost importance for the environment visual comfort. The 12464-1:2002 standard did not contain any provisions concerning these surfaces whilst the 12464-1:2011 standard establishes that mean illuminance should be: Therefore modelling values not included in the above range may also be accepted.Ĭylindrical illuminance is the mean value of vertical illuminance rotating around a certain measuring point. The negative effects of a poor modelling value can be counterbalanced by daylight. An adequate modelling value ranges between 0.3 and 0.6 in case of a uniform distribution of the lighting fixtures or of a luminous ceiling. The modelling index is the ratio of cylindrical to horizontal illuminance on the same measuring point of the grid. Modelling instead is the balance between diffuse and directional light. Illuminance uniformity must not be lower than 0.1 in both cases. ![]() offices, classrooms, meeting rooms), the mean cylindrical illuminance must not be lower than 150lx. In all rooms where an optimum visual communication is required (e.g. The mean cylindrical illuminance values must not be lower than 50lx on a plane at a height of 1.2m for seated persons and of 1.6m for standing persons above floor level. Therefore an adequate mean cylindrical illuminance value must be guaranteed in all areas where people move. The cylindrical illuminance is aimed at guaranteeing an optimum luminance of all solid objects, people’s faces in particular. Cylindrical illuminance and modelling are two indexes important for visual comfort. ![]() ![]() ![]() If you have to set up a meeting in different time zones like the one shown above, from LA, New York and London, you won’t be able to see all the timezones on your calendar. The con here, is that Google Calendar only shows you one other timezone. And of course, you can link your Google Calendar to MeetingKing or, if you do not want to link your Google Calendar, MeetingKing can automatically import meeting details from meetings that are created in Google Calendar. ![]() This way, you know exactly what time it is in Singapore, when you are scheduling your meeting. Google Calendar is a great tool to use when you want to schedule a meeting with people in different time zones, because it can show you more than one time zone in your calendar. If you want to video call with people in different time zones, then is a great app to use. In this case, the teams can meet online at 9 am, 12 pm and 5 pm respectively. The meeting planner helps you see when is the best time to meet for everyone involved – in this instance, we have teams from Los Angeles, New York and London.Īs you can see, the areas in red are hours that aren’t really viable for at least one team, with the areas in yellow being hours that aren’t convenient. If you want to set up a meeting in different time zones, you can use the meeting planner. Just click ‘World Clock’, and you can search by city, or country, and see what the time is there. If, for example, you want to talk to a new designer you’ve just found in Buenos Aires, Argentina, make it easy for you to see what the time is there.

So if you want to meet people from Singapore, we won’t alert you to the fact that your 2 pm is their midnight. Now, MeetingKing can’t help you find a good time to meet up with your team across time zones (yet). Your Sales team, on the other hand, will see that the meeting starts at 11 am! If you are in New York, and you set up a meeting with your Sales team in Los Angeles at 2 pm (your local time) using MeetingKing, you will see that your meeting starts at 2 pm. Now, I don’t know if you’ve noticed this, but MeetingKing meetings are automatically adjusted to your time zone. How do you schedule a meeting in different time zones? The problems arise, of course, not from the tools we use to actually carry out the meetings, but with finding the time to meet. Here at MeetingKing our team even spans several continents, and communication tools like Zoom, Webex, Google Meet or Skype make that really easy.

So my rafter will be supporting a load of 30 s.f. You can calculate out what that is, but a convenient number to use is 10 lbs per s.f. The load includes the design weight for snow plus the weight of the roof itself. So each rafter is supporting an area of 3' * 10' or 30 s.f. That is the rafter spacing times the horizontal distance between the beams. The math part is figuring out the area and load each rafter will be supporting.
