Image Processing of Biological Liquids Films for Medical Diagnostics

引用

Journal of Electronic Science and Technology 2020年第1期18卷 19-30页

作者： maksim Aleksandrovich Baranov Institute of Physics Nanotechnology and TelecommunicationsPeter the Great St.Petersburg Polytechnic UniversitySt.Petersburg 195251

In this paper, the development of smart medical autonomous technology is considered. An example of a smart medical autonomous distributed system for diagnostics is also discussed. To develop this system for medical image analysis we review several processing methods. The use of the cuneiform dehydration method for medical diagnosis is considered. The experimental results obtained for blood serum dehydrated films are presented. The author proposes an algorithm for the primary identification of structures formed in the films and their use for automated detection of various structures for diagnostic purposes. The paper describes the first stage of image processing, i.e. the selection of filtering types for the correct identification of structural features and characteristics of the images. The results of filtering and some computational results of various types of structures in the films are presented.

Education in cardiopulmonary resuscitation in Russia:A systematic review of the available evidence

作者： Alexei Birkun maksim Glotov Department of Anaesthesiology Resuscitation and Emergency MedicineMedical Academy named after S.I.Georgievskyof V.I.Vernadsky Crimean Federal UniversitySimferopol 295051Russian Federation

BACKGROUND: To summarise and appraise cumulative published scientific evidence relevant to cardiopulmonary resuscitation(CPR) education in *** RESOURCES: We searched Medline, Scopus, Science Direct and Russian Science Citation Index databases from December 1991 to December 2016 to identify studies pertaining to the field of CPR education that were carried out by Russian researchers and/or investigated the topic of interest for Russia/Russian population. Reference lists of eligible publications, contents pages of relevant Russian journals and Google Scholar were also searched. There was no limitation based on publication language or study ***: Of 7 964 unique citations identified, 22 studies were included. All studies were published from 2009 to 2016, mainly in Russian. Only three studies were reported to be randomized controlled. Non-medical individuals constituted 17% of studied populations. Most of the studies aimed to assess effects of CPR educational interventions, generally suggesting positive influence of the training conducted. The studies were highly heterogeneous as for methodological approaches, structure and duration of educational interventions, evaluation methods and criteria being used. Methodological quality was generally poor, with >40% publications not passing quality screening and only 2 studies meeting the criteria of moderate high ***: The results suggest paucity, low population coverage, high thematic and methodological heterogeneity and low quality of the studies addressing CPR education, which were carried out in the Russian Federation. There is a critical need in conducting methodologically consistent, large-scale, randomized, controlled studies evaluating and comparing efficiency of educational interventions for teaching CPR in different population categories of Russia.

Test Time Minimization for Hybrid BIST of Core-Based Systems

引用

Journal of Computer Science & Technology 2006年第6期21卷 907-912页

作者： Gert Jervan Petru Eles Zebo Peng Raimund Ubar maksim Jenihhin Embedded Systems Laboratory (ESLAB) Linkoeing University Sweden Department of Computer Engineering Tallinn University of Technology Estonia

This paper presents a solution to the test time minimization problem for core-based systems. We assume a hybrid BIST approach, where a test set is assembled, for each core, from pseudorandom test patterns that are generated online, and deterministic test patterns that are generated off-line and stored in the system. In this paper we propose an iterative algorithm to find the optimal combination of pseudorandom and deterministic test sets of the whole system, consisting of multiple cores, under given memory constraints, so that the total test time is minimized. Our approach cmploys a fast estimation methodology in order to avoid exhaustive search and to speed-up the calculation process. Experimental results have shown the efficiency of the algorithm to find near optimal solutions.

How does grazing affect community composition and species richness in these grasslands? Species composition was classified by cluster analysis;underlying environmental gradients were explored using DCA.A dataset of 395 relevés was used for classification,and a subset of 79 relevés was used in a DCA to analyze the correlation between vegetation,environment,and grazing *** investigated pastures were classified into four distinctive plant *** site factors altitude,heat load,inclination and grazing impact were found to be the major determinants of the vegetation pattern.A significant overlap between floristic composition and structural and spatial properties was *** majority of the species pool consisted of Middle Asian endemics and Eurosiberian ***,disturbance-tolerant species played a significant role with respect to species composition and coverage of the herbaceous layer in vast areas of southern Kyrgyzstan's mountain *** general,an intense grazing impact is clearly reflected by both species composition and structural variables of plant *** highly diverse and unique ecosystem is modified by an increasing utilization *** order to ma
