Control of the soldering process and failure analysis are an important part of quality assurance at today manufacturers of electronic components and assemblies. Many methods exist – non-destructive and destructive, each ...
In most lasers with optical excitation essential element of the emitter except the active environment and optical resonator is a converter of electrical energy in the exciting light radiation – gas discharge or halogen ...
The electrocardiogram (ECG) is often contaminated with interferences such as drift and tremor. The subtraction procedure has proved its efficiency in removing interferences from the ECG. Development process of such device ...
In the paper work are shown results from researching of a single transistor Buck-Boost ZVS DCDC Quasi-Resonant Converter. Initially an analysis of the electromagnetic processes in the power part of the circuit has been made. ...
This article discusses the methods, the tasks and the material base used in the teaching process for students in signature analysis and cyclic redundancy check. The laboratory training is conducted on FPGA programmable logic ...
An overview of the process of sterilization and disinfection is described in this article. Special attention is turn to the currently used technologies, their advantages and disadvantages. Another subject of the topic is the ...
In this paperwork has been made a study of the elements of an off-grid photovoltaic system for power supplying of telecommunication systems and telecommunication modules. The laboratory model is described. The bi-directional ...
Air quality is a matter of considerable concern as it affects public health, the environment and the economy of developed countries. Recent research has shown that air pollution can increase the incidence of diseases and impair ...
In this paper we present a new photo-sensible device based on ZnO/PEDOT:PSS heterojunction. The formation of ZnO layer was made by electrochemical deposition of Zn from zinc nitrate solution over a transparent ITO electrode ...
