Free Software

Free Software (OSS) – the software (SW) with open source software, which you can legally run, modify and distribute with a few restrictions, or without them. Such software distributed under special types of licenses. What can an organization get from the introduction of the act? * Reduce the cost of acquiring proprietary (proprietary) software. * Modify and customize the act under its requirements. * Become independent software developers. * Reduce management costs by copyright.

In what areas can be used free software? Virtually all known areas of activities (eg: tourism, office management, cryptography, electronic documents, etc.). Answers to these and many other questions you can get at the seminar "Free software: from idea to commercial realization. " Goals / objectives of the workshop: to give you necessary knowledge to use free software in your work, reducing the cost of proprietary software (not free) software support and opportunities to profit from the development and maintenance of the act.

Aixtron Surface

About half the cost of LED-od is determined by these stages of high technology. The need to increase capacity to increase the flux led to the fact that the traditional form of the hull led ceases to meet producers due to lack of heat. It was necessary to bring your chip to the heat conducting surface. In this connection, to replace the traditional technology, and several more advanced SMD-technology, energy (surface montage details – surface mount components) comes to the most advanced technology of soi (chip on board). led technology with ids, is shown schematically in Fig. LEDs made of SMD-and soi technology, mounted (Glued) directly to a common substrate, which can act as a heat sink – in this case it is made of metal. So are led modules, which may be linear, rectangular or circular in shape, be 50 – 75 mm. It is very important to ensure uniformity and control structures on the surface of the substrate.

The cost of facilities for epitaxial growth of semiconductor nitride, developed in Europe (the company Aixtron and Thomas Swan) and the U.S. (Emcore), is about 1,5 – 2 million dollars. Experience of different companies showed that learn to get on the competitive structure of such a setup with the necessary parameters can be a time of one to three years. This is – technology that requires high culture. An important step in technology is the processing of planar films: they are etched, the establishment of contacts to n-and p-layers, the coating metal films for the pins. Film grown on a substrate, can be Cut to a few thousand chips ranging in size from 0,24 x0, 24 and 1×1 mm2. The next step is the creation of these led chips. Necessary to mount the crystal in the case, make contact outputs, produce optical coatings, antireflection surface for the output radiation or reflect it. If it is a white light-emitting diodes, it is necessary to evenly phosphor. We must ensure that heat from the crystal and the corps, to make a plastic dome, focusing radiation in the desired solid angle. About half the cost of LED-od is determined by these stages of high technology.

The need to increase capacity to increase the flux led to the fact that the traditional form Corps LEDs fail to meet the manufacturers due to lack of heat. It was necessary to bring your chip to the heat conducting surface. In this connection, to replace the traditional technologies and few more advanced SMD-tech-energy (surface montage details – surface mount parts) comes the most advanced technology of soi (chip on board). led technology with ids, is shown schematically in Fig. LEDs made of SMD-and soi technology, are mounted (glued) directly to a common substrate, which can act as a heat sink – in this case it is made of metal. So are led modules, which may be linear, rectangular or circular in shape, be rigid or flexible, in short, are designed to satisfy every whim designer. Appear and the led lamps with the same socket as a low-voltage halogen, designed to replace them. And for powerful lamps and spotlights are made the led assembly on a round the massive radiator. Earlier in the led assemblies were a lot of LEDs. Now, as the power led becomes less, but the optical system that directs light beam to the desired solid angle, is playing an increasing role.

National Science Foundation

The interested nanotechnology Goldstein and dreams to improve the two-dimensional teleconferencing Mowry invented kleytroniku about three years ago. Since then they have struggled to find a quick way to describe the idea to potential sponsors. By the way speaking, the National Science Foundation (NSF) and the Pentagon’s research agency darpa to So far scientists have provided some way of funding. Money is allowed to engage in the project and a half dozen specialists and approximately the same number of sympathizers. But the forces and resources while sorely lacking. On Indeed success creators synthetic reality until fairly modest. There are four small robots, called atoms or (claytronic atoms – catoms). The diameter of each – 44 mm, that is, to the nanoscale still very far away.

Robot is surrounded by 24 solenoids. Yet managed to get a couple of these machines interact with each other as do two spinning gears. ‘But as soon as we got these two pieces of stirring, increased the likelihood of our success’ – said Mowry. Ultimately, he hopes to build a sufficient number of two-dimensional cut to start experimenting with changes of form. Then plans to establish immediately a hundred robots the size of a tennis ball that can move in three dimensions. To construct the cut diameter of 1 millimeter, according to the authors of the project, it will be very difficult, but, apparently, it’s inevitable. It is assumed that the cut should have a spherical shape and have no moving parts. He probably will be covered by the electromagnets, so that one robot could join another and in general – to navigate.

How To Choose A Supplier Of Industrial Robots? Expert Advice

Today industrial robots are becoming an integral part of modern production, a mandatory attribute of the next, higher technological and qualitative level. Their use can create fully automated jobs, land, shops, factories, greatly increasing efficiency. You, too, decided to robotize one of the processes? Then take your time and read this article – it is for you. And even the not so important what you're going to raise to a higher technical level. Much more important not to be mistaken with a choice of provider of this technology, where the main criterion is competence of a future partner. Often, many admit the same error. In the end, as in the well-known adage: like the best, come out – as always. That's the scenario, the situation evolved, what has happened in Krasnodar Territory. Unfortunately, it is not trivial. After receiving preliminary information on the exhibition, and, to charm showroom, where the industrial robot shows some movement, the customer has signed a contract to supply Robot systems arc welding. However, subsequent technological problems that have arisen at the stage of commissioning, forced him to flee to the court. At the same time, all good beginnings to implement an industrial robot ended. It does not matter that, in consequence, had won a lawsuit – the main result was the lack of robotic technology in the workplace. The sad fact of real life For any enterprise, located in the search, the most important task – is not mistaking the right choice, entrusting the implementation of planned, competent partner (system integrator).

Digital Flow Sensor Gas

The use of microelectronic (MEMS) sensors in process control systems – the main line of development of modern means of automation. Introduction of smart sensors is driven largely by low cost (thanks to the use of high technologies in their production). However, the situation in the market of gas flow sensors, thermal conductivity and the like, using in its structure, precision temperature control system heating gas to be measured, it remains at 20 30 years ago. Most common in hot-wire anemometer acquired three-element modules consisting of a heater and two thermometers based on measuring the temperature difference between the gas before and after heating

The advantage of this module is the clear physical principle of operation and use as active elements in the traditional wires, and the latest designs – thin-film thermistors. Their common drawback is the low resistance of thermistors, and consequently overheating measuring current, which reduces the accuracy of the instrument. The desire to minimize the size of the module, its thermal inertia and energy consumption requires placing the module inside the measured flux, and therefore must take into account the gas-dynamic characteristics that affect heat transfer. In particular, the thin-film design is imperfect in gasdynamic regard as a platform. Conditions of flow and heat transfer due to forced convection are dependent on many factors: the geometry of the channel, location relative to the flow core, the angle attack, the presence of turbulence, and others is not measured by the gas temperature and the temperature sensor housing that does not introduce errors only in the steady state..
