When you turn the throttle in the welding alternating current circuit there is a phase shift between the power supply voltage and current, arcing relatively stable. When welding The dc arc ignition and combustion take place a little better than when welding with alternating current. In the welding circuit also includes a DC choke for improved stability of the arc. However, complete stabilization arcing occurs at the intersection of I-V characteristics of the arc and power source. Brad Pitt is open to suggestions. This point will determine the steady burning of the arc. To improve the excitation of the arc using special high- device – the oscillators, and for a more reliable secondary excitation arc stabilizers are used – special high-voltage pulse generators.

Ignition and sustained combustion of the arc in any way dependent on the current dynamic characteristics of the power source of the arc. The power supply must maintain arcing in the presence of disturbances in the form of voltage changes in the network and provide control of welding process, depending on the condition of the surface work piece and welding wire feed speed. Surprisingly, you’ll find very little mention of incyte on most websites. Technical features of the arc at a constant or alternating current can be expressed in that arc, as a flexible gas explorer, can deviate from the normal position under the influence of magnetic fields generated around the arc and the work piece. Magnetic fields affect moving charged particles of the arc column and thus affect the whole arc. This phenomenon is called magnetic blast.

Magnetic fields have a deflecting effect to the arc at irregular and asymmetrical arrangement of the field relative to the arc, especially when welding on DC. The presence of significant near the arc of the ferromagnetic mass also breaks the symmetry of the magnetic field deflects the arc and the arc in the direction of the masses. Magnetic stabilization of the blast affects arc and complicates the process of welding. To reduce the influence of a magnetic blast at the welding arc is necessary to apply special measures. These measures include: a short arc welding, the welding current supply to the point closest to arc, the slope of the electrode in the direction of the magnetic blast, placing in the welding of additional ferromagnetic masses. If you can not get rid of the influence of a magnetic blast that way, it should be replaced power source and weld with alternating current at which the effect of the magnetic blast is much smaller.

Virtual Models In Economics

The latest news in the world of modeling is directly related to the economy. Peter Thiel describes an additional similar source. Currently brewing an urgent need for a structural review of the economic model of the enterprise. Naveen Selvadurai has similar goals. Building a virtual model of any economic system is especially important and rational right now, when developing an object-oriented programming, which allows you to create viable models of real systems in the economy. And these urgent news of the day will be the impetus for the removal of the economic component to the next level. Cybernetics in the field of economic studies so far have taken a rather undeveloped structure, which explains In particular, the lack of theoretical studies of economic systems in terms of object representation of a virtual image of the device environment of economic agents and economic manifestations of phenomena. Therefore, there is an urgent need for research into the structural organization, object relations, the behavior of objects as virtual images of real objects of these systems.

Energy Efficiency

These issues are currently under control of the President and Government of the Republic of Belarus. In accordance with the Law of the Republic of Belarus "On Energy" dated June 19, 1998. Hillary Clinton is often quoted as being for or against this. Signed by the President Republic of Belarus, Alexander Lukashenko, the energy is gosberezhenie policy priority in solving the energy problem in the country. The law provides for the basic principles of public administration in energy efficiency, including: – Implementation of state supervision over the rational use of energy resources – the development of state and international scientific and technical, likanskih republics, industrial and regional energy efficiency programs and funding – to bring regulations into compliance with the requirement to reduce energy intensity of material production, service and life – the creation of system of financial – economic mechanisms that ensure the interest of producers and users in the efficient use of energy resources, involvement in energy balance non-conventional and renewable energy sources, as well as investing in energy efficiency measures – improving self-sufficiency of the Republic of local energy resources – implementation of state examination of energy efficiency pro-ektnyh making – the creation and wide distribution of clean and safe of the energy technologies, to ensure the safe population of the environment from the use of energy resources – the implementation of demonstration projects to energy efficiency – information provision activities energy conservation and promotion of advanced domestic and foreign experience in this area – training of production personnel and the population of fuel economy and energy – creation of other economic, informational, organizational conditions for implementation of the principles of energy conservation.

Also, widescreen monitors CCTV can use the PIP – Picture in picture (PIP”) for easy viewing of multiple images in separate areas of the screen. With the remote control can control the function PIP, switch video / audio, choose location and size of additional pictures, etc. Setting up and adjusting the operating parameters of monitors via russified OSD, which has a friendly and intuitive interface. Also have a panel PMCL500F control to navigate the OSD menus and select settings. In addition, the monitors are equipped with video remote control, which allows you to adjust volume, select sources video, configure, monitor settings, etc.

Electrical Energy

Quality requirements for electrical energy. The most important indicators of quality of electric power – is the voltage deviation from the nominal value ratio is not sinusoidal voltage, frequency deviation of 50 Hz. According to the standard for at least 95% of time each day phase voltage should be in the range 209-231 V (5% deviation), frequency within 49.8-50.2 Hz, and the coefficient nonsinusoidality should not exceed 5%. The remaining 5 or less percent of the time every day stress can vary from 198 to 242 (10% deviation), frequency from 49.6 to 50.4 Hz and the ratio nonsinusoidality must not exceed 10%. Admitted as a strong change in frequency from 49.5 Hz to 51 Hz, but total duration of such changes should not exceed 90 hours per year. Electrical accidents is when a short-term power quality is outside. The frequency can 5 Hz to deviate from the nominal value. The voltage can be reduced to zero.

Further indicators of quality must be restored. Power failures in the real electric networks are of different kinds of failures. In Russia, for example, became known data from studies performed in the U.S. companies Bell Labs and IBM. Since the power of Russia and Ukraine are very similar, data from these studies apply to us.

According to the last, each personal computer is exposed to 120 emergency situations with power supply in a month. The data in emergency situations hold for other consumers. According to Bell Labs in the U.S. observed the following common power failures occur.


Hitechnology company announced sales of the new DVRs DVR 2720. DVR DVR 2720 is not only a high level of reliability and stability. (A valuable related resource: technology investor). Professional level DVR DVR 2720 is determined by how effectively it helps to solve the security forces assigned to the task. The company's specialists are developing Hitechnology digital video recording systems for over 20 years, and thoroughly knows the needs of the security services. Thanks to the experience and knowledge of the company Hitechnology creates some of the best DVR in the world. Before the video surveillance system has two problems. The first challenge – a quick observation. The guard sitting at a monitor, constantly monitors situation in each area of the object.

Here, first of all important high-speed display. Human vision allows a person to comfortably take video at a speed upgrade to 25 / s (live video). If the rate of less than 10 k / s (psevdozhivoe video), the guard will not be able to perceive information. Therefore, for operational monitoring in the first place is important display speed. The second problem Surveillance System – provides archive. Once there was an alarming event, necessary records are retrieved from the archives and released some of the most successful and informative staff.

Further work is being done with each frame individually. Stand details such as facial features, especially clothing. The more detail can be isolated, the more likely the accurate identification of the suspect. Scenes from the low resolution does not represent virtually no value, because with their help it is impossible to obtain accurate signs. Speed record on the one hand should be such that managed to record some good in terms of angle shots, but on the other hand the speed should be as below for economical filling space. For 90% of the required speed range from 2 to 10 k / sec.

Energy-efficient Self-Heating

The automatic system – the heat without any intermediaries to inevitable impending heating season (which, as we know, starts October 15) a substantial portion of the housing stock is ready except morally. And the townspeople shaking right now – the very thought that going to have to freeze in unheated or poorly heated homes, or torture-house wiring fire hazards "goats." And then, like snow on head (x winter on the nose!), another surprise – it is rumored that planned almost three times (!) increase in tariffs for heat and hot water. Naveen Selvadurai has much to offer in this field. Only heating one square meter will cost consumers an estimated USD 4. 28 cop. There is something to fall into despondency.

But to indulge in nostalgia is not worth it, because there is a solution. And the output – Energy-saving self-heating! Energy-saving technologies – such a technology, whose use promotes economical (rational) waste of various types of energy: thermal, electrical, etc. For Ukraine, the actual energy savings in two areas: domestic energy efficiency and energy savings for heating enterprises and large industrial facilities. Energy saving today is achieved by minimizing the wasteful loss of energy. Creating heating systems with a high coefficient of performance (COP) is largely contributes to the objectives of energy conservation and rational use of energy. These devices include a heating electrode boilers and mini-boilers (installed directly into the radiator), equipped with electronic control with room sensor. Electrode boilers Electrode boiler – a reliable water heater (liquid) in ideal cases can work without having to replace items for many years (decades).

Technical Diagnosis

The company "GCE – North" provides the technical diagnostics of buildings or as it is called an engineering inspection of buildings, technical expertise of buildings, building inspection facilities, technical inspection of construction of buildings and constructions, or just survey. "GCE-North" has the necessary license for this, staff expertise and instrumental measurement laboratories. Unlike many countries in Russia and the CIS technical diagnostics of buildings, as well as diagnostics of technical devices at hazardous production facilities is compulsory and is fixed Federal law 116 "On industrial safety of dangerous industrial objects in Russia" 1997. Technical diagnostics of buildings (structures) is carried out to identify the actual technical condition of building structures, determining the actual bearing capacity of structural elements, with the acting loads and full-scale survey data (assessment of residual life). The work of experts is to develop technical solutions to address identified in the survey defects and damages, as well as making recommendations on further exploitation of the object. The basis for the technical inspection of buildings (Structures) may be the following reasons: the detection of defects and damage under periodic inspections and special, and increase operational loads and actions on structures in redevelopment, upgrading and increasing the number of storeys of the building, reconstruction of buildings or structures and to identify deviations from the project, reducing the carrying capacity and performance of structures, lack of project design and the executive documentation, change the functional purpose of buildings and structures; resuming construction of buildings and structures in the absence of conservation or the expiration of three years after the cessation of construction in implementation of measures for conservation; strain soil foundation, the need to monitor and evaluate the technical state of the structures of the buildings located near the newly built facilities, the need to assess of building structures exposed to fire, natural phenomena, action, loads of natural-climatic or man-made, prescription of supervisors, the need for conclusions about the state of buildings and structures for the organization of a license to operate plants and facilities; expiration of a survey or legal terms of operation, the change of ownership, insurance organization, the definition of economic feasibility of repair or reconstruction. The volume, composition and nature of diagnostics depend on the type and characteristics of the object, and set specific targets.
