Based on the analysis of seismic signals’ characteristics from a moving person and vehicles, the article proposes and substantiates the expediency of using the temporal parameters of seismic signals for moving objects recognition by remote autonomous seismic devices. Simple and sufficiently reliable methods for moving objects recognition have been formulated. The testing of such methods was carried out using the developed autonomous seismic device. The technical and economic efficiency of the proposed methods in comparison with known solutions based on other principles is pointed out. The aim of the work is to determine improved temporal methods for recognition of a moving person and vehicles and the effectiveness of their use by remote autonomous seismic devices. Cur-rently, the most promising seismic devices for the detection and recognition of moving objects are considered to be devices that use spectral and spectral-temporal methods of seismic signal processing. This is mainly due to their high probability of the objects correct recognition. But the use of these methods leads to a significant increase in the information and energy consumption, which is extremely undesirable for the remote autonomous seismic devices and systems based on them. The article proposes to use the energy-efficient temporal methods of seismic signal processing and the improved recognition methods based on the use of temporal parameters of seismic signals to recognize moving objects in these cases. To implement this and to reduce false alarms of the seismic devices, when animals penetrate into their detection zone, in contrast to the known devices, a temporal selec-tion criterion related to the motion characteristics of medium and large animals is additionally intro-duced into the recognition method of a moving person. The testing of the recognition methods has shown that the proposed methods allow autonomous seismic devices to have both the insignificant power consumption and a significant value of the probability of the moving objects correct recognition. Compared with spectral, time-frequency and statistical methods for moving object recognition, the proposed temporal methods are much simpler and allow to design the remote autonomous seismic devices with minimal energy consumption.","PeriodicalId":367487,"journal":{"name":"Sensor Electronics and Microsystem Technologies","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124536611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have shown that semiconductor magnetically sensitive transistor structures (MTS) can be the basis of effective magnetic field sensors, as well as sensors of the other physical quantities. However, such sensors practical application requires investigation of the destabilizing factors influence on the MTS themselves to ensure high metrological characteristics. Temperature is among these main factors. The study of the environment temperature influence on the main MTS characteristics is the subject of this work. The mechanisms of the temperature influence on the MTS, their characteristics dependences, in particular, the conversion parameters from the point of view of possible use in sensors, are analyzed. problems study in order to optain stronger knowledge of the temperature effect on the MTS characteristics. The experimental and theoretical temperature dependences of the drift MTS (DMTS) current transmission coefficients in the magnetic field, the coordinate of the maximum mangitosensitivity site dependence on temperature, and the dependence of the DMTS mangitosensitivity on temperature for different materials are given.

Sensing the Auger spectra in atomic systems and solids gives the important data for the whole number of scientific and technological applications. When considering the method principles, the main attention is given as a rule to the models for drawing chemical information from the Auger spectra and to the surface composition determination methods by the Auger spectrum decoding. It is just the two-step model that is used most widely when calculating the Auger decay characteristics. The relaxation processes due to Coulomb interaction between electrons and resulting in the electron distribution in the vacancy field have no time to be over prior to the transition. In this paper the combined relativistic energy approach and relativistic many-body perturbation theory with the zeroth order density functional approximation is applied to determination of the energy and spectral parameters of the Auger decay for the Na, Si, Ge, Ag solids. The results are compared with reported experimental results as well as with those obtained by alternative theoretical schemes. The important point is linked with an accurate accounting for the complex exchange-correlation (polarization) effect contributions and using the optimized one-quasiparticle representation in the relativistic many-body perturbation theory zeroth approximation, which significantly affects the agreement of theory and experiment.","PeriodicalId":367487,"journal":{"name":"Sensor Electronics and Microsystem Technologies","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130818438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the basis of the Hall effect measurements, the dependencies of the Hall EMF on the induction of an external magnetic field for the electron irradiated n-Ge single crystals, coated with a layer of the epoxy-dianon resin (without fillers and with fillers of the powders of iron and aluminum) have been obtained. These single crystals were irradiated by the electrons with an energy of 10 MeV and the flow of Ω=5·1015 el./cm2. From the analysis of these dependencies it follows that they are linear for germanium single crystals, coated with a layer of epoxy resin without filler and with the filler of aluminum powder in the whole range of investigated magnetic fields. For germanium samples, coated with a layer of epoxy resin with filler of an iron powder, there is a slight deviation from the linearity of such dependencies for the magnetic fields up to 0,3 T, which is explained by the additional magnetization of iron powder. It was established that the presence of a protective epoxy resin layer significantly reduces the sensitivity of germanium single crystals to the influence of an external magnetic field. The presence of residual magnetization for irradiated n-Ge single crystals, coated with an epoxy resin with the filler of iron powder can be used for developing an energy storage systems based on such single crystals. is explained by the additional magnetization of iron powder. The presence of residual magnetization of the iron powder filler and the correspondingly induced additional Hall EMF can be used for developing an energy storage systems based on irradiated n-Ge single crystals, coated with an epoxy resin with the filler of iron powder. It was established that the presence of a protective epoxy resin layer significantly increases the protection of germanium single crystals from the influence of large radiation and magnetic fields. This is important in designing Hall sensors based on germanium single crystals, which can function in extreme conditions action of such fields.","PeriodicalId":367487,"journal":{"name":"Sensor Electronics and Microsystem Technologies","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133040793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
