  • Study of SiGe HBT performance in a transition down to sub-100 nm technology

    There is discussed an influence of n-p-n HBT scaling on its RF performance in the article. The behaviour of cut-off and maximum frequency of DUT at the transition from 0.18 um down to 0.09 um BiCMOS technology is demonstrated, its dependence from construction and technological variations of the heterojunction bipolar transistor, as well. It was shown, that the approach called "direct" scaling appeared to be inappropriate as a frequency-increase method and some constructive and technological recommendations were discussed, including Ge profile shape, impact of deep collector implantation dose and cap-layer thickness.

  • Theoretical understanding of the features of the tactics of interrogation of persons with mental disorders

    The material provides an analysis of cross-cutting issues of tactics of interrogation of persons with mental disorders; The author focuses on the fact that investigated the problem is quite complex in terms of legal, criminological, criminal law, medical-social and psychological aspects. The purpose of research - the study of tactical and procedural features of interrogation of persons with mental disorders. Methods. The methodological basis of the study constitute a universal method of knowledge, reflecting the dialectical relationship of theory and practice, as well as other proven methods of scientific research: the method of theoretical analysis of the sources of the problem, analysis and synthesis, induction and deduction, sociological, psychological and statistical methods (study and analysis of the content of the materials criminal cases and statistical data, questionnaires, survey). Results. Thus, analyzing the modern ideas of scientists and practitioners concerning the use of the terms "mental disorders", "mental illness", "mental deficiencies" and so on., We can conclude that it is more correct to use the term "mental disorder"; defects psyche available to all categories of persons under interrogation, it is a very complex and diverse phenomenon and should be the subject of study sciences such as criminal law, process, criminology, criminal law enforcement, forensic psychiatry and criminology; legal psychology.

  • Development of a universal data acquisition system with control functions based on the analog-to-digital converter

    Abstract: Operation of motor transport and special equipment is carried out in difficult conditions, the impact of environmental conditions (temperature, humidity, dust, wind, solar radiation) and changes in modes of operation of the machine. This affects the performance of equipment, the number and complexity of repairs. Away from fixed bases (in the field), the problem is particularly acute repairs. One of the most energy-intensive and expensive works are welding (welding parts with a break, welding cracks, fusing metal layer on the worn surface, metal cutting). In this work the welding equipment affect the voltage drops in the supply mains, therefore, produces a large number of failures such equipment. After the equipment is accompanied by an increased amount of electric power consumption, this results in material costs. Previously proposed equipment has improved mass, which reduces the efficiency of the welding. Based on this study was proposed innovative design welding inverter using the resonance effect, with enhanced reliability, low-cost design version (in terms of mass production). In order to improve the reliability and reduce the cost of the proposed design of inverter proposed a number of new approaches. Full-bridge inverter is studied welding power source with the implementation of the resonance effect with a stable and smooth operation, high reliability, because the circuit of the inverter is not sensitive to changes in the supply voltage.

  • Developing a sliding blade snowplow

    based on an analysis of the methods and schemes snow removal from roads and sidewalks it revealed that there is a snow plow, which would be cleaned in a single pass only the side of the road in the middle of the road cleared. At the same time to solve this problem are also two cars. In accordance with this work set a goal: increasing productivity snowplows. To explore this issue were based on the analysis of working bodies of snow plows developed and investigated a new type of dump actuator for snow removal from roads. It was determined that there is an additional resource to increase machine productivity. This is achieved by improving the design of the working body. This will not increase the resistance of the machine, because proposed symmetrical design with rotating blade and sliding half, which will reduce the resistance and to ensure stability.
