New Time-Frequency Transient Features for Nonintrusive Load Monitoring

A crucial step in nonintrusive load monitoring (NILM) is feature extraction, which consists of signal processing techniques to extract features from voltage and current signals. This paper presents a new time-frequency feature based on Stockwell transform. The extracted features aim to describe the shape of the current transient signal by applying an energy measure on the fundamental and the harmonic frequency voices. In order to validate the proposed methodology, classical machine learning tools are applied (k-NN and decision tree classifiers) on two existing datasets (Controlled On/Off Loads Library (COOLL) and Home Equipment Laboratory Dataset (HELD1)). The classification rates achieved are clearly higher than that for other related studies in the literature, with 99.52% and 96.92% classification rates for the COOLL and HELD1 datasets, respectively.

Development of criteria for the selection of experts for the scientific and scientific-technical expertise of projects. Analysis of world experience

Science, technology and innovation are categories of activities that increase their impact every year. These categories are interrelated, however, on the other hand, they are such that significantly differ from each other. Science promotes the development of innovative technologies as new knowledge that serves as a direct source of ideas for innovative technological opportunities; as a source of tools and methods for more efficient engineering design; as research equipment, laboratory and analytical methods used in research that ultimately find their application in design or manufacturing practice, often through intermediate disciplines; as a research practice — a source of development and assimilation of new human skills and abilities, which may ultimately be useful to technology; as a knowledge base that allows more effective use of strategies for applied research, development and improvement of new technologies. However, there is another way in which science acts as an engine for the development of innovation: as a knowledge base for assessing the feasibility of projects and analyzing technologies in terms of their broader social, economic and other types of benefits. This article is devoted to the study of the situation in the scientific, scientific and technical expertise of scientific projects. The basic concepts for conducting scientific, scientific and technical expertise were defined. The world experience in the selection of experts for scientific, scientific and technical expertise was analyzed. The key provisions and mandatory conditions were highlighted, in the presence of which the selection of experts for scientific, scientific and technical expertise will be successful. Recommendations regarding the settlement of the issue of selection of experts for scientific, scientific and technical expertise in Ukraine were given.

Managing Research Animal Specimens and Laboratory Safety

The procedures necessary to perform testing in a veterinary diagnostic laboratory have inherent associated risks to personnel in regard to exposure to infectious agents. In research institutions animals can be experimentally infected, acquire naturally occurring infections and can also be exposed to other hazards such as toxic chemicals or radiologic entities. A critical component of the use of animals in a research environment is the collaboration between the responsible researcher and the veterinary diagnostic laboratory with the institutional health and safety professionals to ensure that the proper engineering controls, personal protective equipment, laboratory procedures and training are in place for personnel working with the animals or their specimens. Unlike the typical researcher, the veterinary diagnostic laboratory generally has to be equipped to safely process and work with a wide range of potential hazards where the communication of pertinent information from the researcher to the diagnostic laboratory regarding the identity of the potential hazard is paramount. Diagnostic laboratory design, safety equipment, personal protective equipment, laboratory procedures, occupational health program and personnel training must be sufficient to address hazards based on a risk assessment performed in conjunction with safety professionals. This article will summarize safety considerations with the various areas of concern in the operation of a diagnostic laboratory for research animal specimens.
