A mixed multiscale FEM for the eddy current problem with T,Φ-Φ and vector hysteresis

Purpose This work introduces an efficient and accurate technique to solve the eddy current problem in laminated iron cores considering vector hysteresis. Design/methodology/approach The mixed multiscale finite element method based on the based on the T,Φ-Φ formulation, with the current vector potential T and the magnetic scalar potential Φ allows the laminated core to be modelled as a single homogeneous block. This means that the individual sheets do not have to be resolved, which saves a lot of computing time and reduces the demands on the computer system enormously. Findings As a representative numerical example, a single-phase transformer with 4, 20 and 184 sheets is simulated with great success. The eddy current losses of the simulation using the standard finite element method and the simulation using the mixed multiscale finite element method agree very well and the required simulation time is tremendously reduced. Originality/value The vector Preisach model is used to account for vector hysteresis and is integrated into the mixed multiscale finite element method for the first time.

The use of local ingredients and M-Bio produces feed that can be stored for a week with complete nutrient content. In the long term, this activity will increase knowledge, skills and independence of farmers. Results of evaluation show attitude of farmers who are enthusiastic and satisfied with this activity.

Determination of 3-Monochloropropanediol and Glycidol in Food Products

Due to the increasing globalization of food markets, there are evolving new challenges for maintaing food safety. The current problem is the development of analytical methods for 3-monochloropropanediol ester and glycidol ester, which are food contaminants of concern for the scientific community. The levels of 3-monochloropropanediol ester and glycidol ester in certain food products are controlled by the European legislation. However, the maximum allowed concentrations and uptake limits for various food products are permanently revised. Therefore, we aimed to determine 3-monochloropropanediol ester and glycidol ester in various food products, which may contain vegetable oils. We analyzed food samples obtained from local food shops, predominantly low-priced products, which are more likely to contain vegetable oils, and adulterated milk fat. The levels of 3-monochloropropanediol ester and glycidol ester were determined indirectly by analyzing free 3-monochloropropanediol and glycidol ester obtained by hydrolysis and derivatized with phenylboronic acid. Samples were analyzed by GC-MS/MS on a triple-quad mass spectrometer.

GIS Based Analysis Freight Demand in Jisr Diyala Area.

In determining the economy of the region, freight transportation plays a major role. Usually, efficient freight distribution networks take care of reducing the cost of transporting goods to and from transportation facilities. The purpose of this analysis is to find an alternative route for the Jisr Diyala entrance, using aggregate freight data and Spatial Analysis techniques from GIS, in particular, to analyze the travel pattern of intercity truck traffic. Shipping data is obtained through roadside surveys and interviews which represent the primary source of data for this study. The study concludes by determining the best route for trucks, which reflects the current path in fact, and proposing a path to split trucks from small vehicles to avoid the current problem, as the questionnaires revealed that the largest amount of goods type was for construction materials by 32%, with the majority of commercial areas intended for users. The path and the study of the paths that link them. Using GIS techniques, various assessments of freight demand are made, and producing this analysis is helpful for decision-makers to apply the right decisions.

THE SPECIFICS OF EXTREMIST-TERRORIST TEXTS (ON THE MATERIAL OF THE AUDIO RECORDINGS OF THE “GUIDE TO THE ISLAMIC STATE” CHANNEL, BANNED ON THE TERRITORY OF THE RUSSIAN FEDERATION)

The article is devoted to the current problem of verbal extremism. The purpose of the study is to analyze the concept of verbal extremism and its manifestation in texts of extremist-terrorist orientation. The peculiarities of the texts of extremist-terrorist orientation are due to the fact that this discourse is characterized by internal and external precedence. The scientific novelty lies in the study of verbal extremism on the material of the audio recordings of the "Guide to the Islamic State" channel. As a result, the author identifies and characterizes the types of extremist speech acts.

A Review on Forwarding Strategies in NDN based Vehicular Networks

Named Data Networking (NDN) is a model that has been proposed by many researchers to alter the long-established IP based networking model. It derives the content centric approach rather than host-based approach. This is gaining even more traction in the wireless network and is able to replace the conventional IP-based networking. Up to now, NDN has proven to be fruitful when used with certain limitations in vehicular networks. Vehicular networks deal with exchanging information across fast moving complex vehicle network topology. The sending and receiving of information in such a scenario acts as a challenge and thus requires an effective forwarding strategy to address this problem. Different research work has provided with multiple forwarding strategy that solves the current problem up to some limit but further research work is still longed for to get an optimum solution. This paper provides a brief survey on current existing forwarding strategies related to vehicular networks using NDN as well as providing information on various resources and technologies used in it.

Analysis of Russian dissertation research on wrong behaviour from the standpoint of the theory of sets by Dimitri Uznadze modified by Aleksandr Asmolov

In the review article, in the context of discussing the current problem of clarifying the causes of wrong behaviour and developing approaches to its correction based on the analysis of literature sources; the hypothesis is substantiated that behavioural errors in all their diversity are a consequence of the actualisation of sets at different levels of organisation. The scientific novelty of the research is in the fact that in order to achieve this goal, a comparative analysis of wrong behavior has been carried for the first time out from the standpoint of the classical theory of sets by Dimitri Uznadze and from the standpoint of modification of this theory by Aleksandr Asmolov, according to which human activity is stabilised by three types of sets at different levels of organization – operational, purpose and semantic. For the factual argumentation of the results of the analysis, all dissertations (46) that had been defended in Russia over the past 30 years as part of the study of wrong behaviour were studied. In these works, errors are described and discussed, which can be conditionally subdivided into three main large groups – automatic errors, errors of failure to achieve the goal and errors of the meaning of activity. These groups of errors have signs of level sets, and that confirms the hypothesis formulated in this article. The development of approaches to the correction of wrong behaviour on the basis of psychological mechanisms of formation and correction of sets at different levels of organisation within the framework of the concept of set activity by Aleksandr Asmolov.

DEVELOPMENT OF CRITERIA FOR EVALUATING THE QUALITY OF TRAINING FOR OFFICIALS OF THE INTERNAL AFFAIRS AGENCIES OF THE RUSSIAN FEDERATION AS CANDIDATES FOR PARTICIPATION IN PEACEKEEPING MISSIONS

The objective of this exercise is to resolve the existing contradiction between the need for an objective assessment of the quality of training of IAO candidates for peacekeeping missions, based on specific training objectives, and the existing system for obtaining specific results of educational activities by means of a quantitative method for evaluating knowledge, skills and skills (pedagogical testing). This article deals with the current problem of assessing the quality of the educational process at the All-Russian Institute for Advanced Training of Staff of the Ministry of Internal Affairs of the Russian Federation when preparing candidates for participation in United Nations peacekeeping missions. The scientific novelty of the work consists in presenting private criteria for the formation of professional competence of the international UN police (motivational, communicative-activity, cognitive and personal-result) and indicators to each of these criteria. As a result, a system of objective and comprehensive evaluation of the educational process has been developed.
