Application of Fuzzy Algorithms for Controlling the Modes of Solar Panels in Technological Monitoring at Peak Load

The functional structure of geoecological and technological monitoring systems is analyzed. It is shown that the complication of the multifunctional automated system of geoecological and technological monitoring (MF AS) and the increase in its dynamics aggravates uncertainty of its condition estimation. An uncertainty model of the state of a multifunctional automated system of geoecological and technological monitoring has been developed. To implement the model, fuzzy sets of linguistic estimates fluctuating in time are obtained. The application of fuzzy algorithms to control the modes of solar panels and the detection of failures in thermoelectric systems has been carried out. As a result of the simulation, an increase in the efficiency of the thermoelectric system was revealed by reducing peak loads by 28% and, accordingly, reducing the probability of failures by almost 2 times

A technological monitoring of the die working surfaces for the pulse stamping

Целью работы является разработка теоретических основ мониторинга на основе математического описания процессов формирования, деформирования, упрочняющей обработки и эксплуатации матриц для импульсной металлообработки. Обоснована связь между процессами формирования пластического нагружения и эксплуатационных нагрузок, матриц и их качества возможно в результате определения критериев принятия решений при мониторинге процессов формоизменения тонколистовых заготовок. Использованы модели накопления трещиноватости в процессе пластической деформации. Считается, что приращение трещиноватости при пластической деформации является случайной величиной. По данным о напряженно-деформированном состоянии, а также пластичности металла, задавая вероятность разрушения металла Р, определяется степень использования запаса пластичности или предельная деформация при риске получить разрушение по трещинам с вероятностью Р. При выборе рационального способа упрочнения материала рабочей полости матрицы и метода формоизменения заготовки необходимо также проанализировать: степень теплового воздействия на металл, качество заготовок и литых элементов матрицы, технологические возможности, производительность, степень автоматизации и механизации, экономичность, экологичность. Установлены наиболее существенные факторы, влияющие на жизненный цикл матриц. Рассмотрены кинетический подход для определения параметров упрочняюще-стабилизирующей обработки матрицы и необходимость использования критериев упрочнения. Предложено скалярный параметр повреждаемости в условиях импульсного силового нагружения умножить на коэффициент динамичности. Его значение лежит в пределах 0,05-0,5 и зависит от материала, величины и длительности нагрузки. Предложен способ упрочняюще-стабилизирующей обработки рабочих полостей матриц.The aim of the work is to develop the theoretical foundations of monitoring based on a mathematical description of the processes of formation, deformation, hardening processing and operation of matrices for pulsed metal working. The connection between the processes of formation of plastic loading and operational loads, the matrices and their quality is possible as a result of the determination of decision criter ia when monitoring the process of forming thin sheets. The most significant factors affecting the life cycle of the dies have been determined. The kinetic approach to determining the parameters of the hardening and stabilizing treatment of the die and the need to use the hardening criteria have been considered. The scalar damage parameter in the conditions of the pulsed force loading is proposed to be multiplied by the dynamic coefficient. Its value lies within 0.05-0.5 and depends on the material size and the duration of the load. On the basis of tasks decision the fluctuation theory a ground over of connection is brought between the processes of strengthening-stabilizing treatment of working cavities of the die is proposed. A method for strengthening-stabilizing treatment of working cavities of the die is proposed. Models of the accumulation of fractures in the process of plastic deformation have been used. It is believed that the increment of fractures during the plastic deformation is a random value. According to the data on the stress -strained state, as well as the plasticity of the metal, setting the probability of the metal failure P, the degree of utilization of the plasticity stock or the ultimate deformation is determined when there is a risk of the fracture of cracks with the probability R. When choosing a rational method of strengthening the die working cavity material and the blank forming method it is also necessary to analyze the following: the degree of thermal effects on the metal, the quali ty of blanks and cast die elements, the technological capabilities, the productivity, the degree of automation and mechanization, the efficiency, the environmental friendliness. The most significant factors affecting the life cycle of the die are determined. The kinetic approach to determine the parameters of the hardening and stabilizing treatment of the die and the need to use the hardening criteria are considered. A scalar damage parameter in the conditions of the pulsed force loading is proposed to be multiplied by the dynamic coefficient. Its value lies within 0.05-0.5 and depends on the material, size and the duration of the loading. A method for a strengthening-stabilizing treatment of the working cavities of the dies is proposed

Carpe Diem: Privacy Protection in Employment Act

What these employees have in common is that their employers technologically monitored them, invading their privacy, yet their lawsuits were dismissed.6 Indeed, scholars generally agree that the law in the United States fails to adequately protect private sector employees from technological monitoring by their employers.7 This article proposes a solution: federal legislation intended to permit private sector employers to monitor their employees when necessary but to also provide their employees adequate privacy protection.8 Section II reviews the nature and extent of the problem of technological monitoring of employees by their employers. Section III surveys the laws and proposed legislation that serve as a foundation for the Proposed Act and articulates the strengths and weaknesses of the various approaches in comparison to that of the Proposed Act. Section IV illustrates how the Proposed Act flows from but is different than the prior work of scholars addressing the issue

Technological Monitoring Applied to Survey-Based on Brazilian Patent Applications about PEMFC

The present study aims to show the importance of patents as an instrument of technological innovation and to assess the relevance of technology of PEMFC in Brazil by means of the technological monitoring methodology from 1996 to 2005. This study used different Industrial Property Databases (INPI-BR, ESPACENET and DWPI), in order to retrieve the BR applications in each database. Relevant keywords as “fuel cell” were used in combination with specific IPC (H01M8) in order to assess the main applicants, countries, IPCs and technological innovation over time. In Brazil, the country holding more requests in this area is the United States (US) with 53,7% of the patent applications, while Brazil (BR) accounts for 4,4% of the total requests. It was also observed that the North-American company, UTC Fuel Cells comes on top of the list and that there were no patent applications of Brazilian origin (BR) in other countries

From smart to good cities: shifting the focus from technology to quality of life

People now use a number of terms to classify cities. The commonly used ‘smart city’ is preferred by tech companies. But their idea of ‘smart’ focuses on big data collection and narrow technological monitoring. Alternative terms include liveable, healthy, sustainable, adapting, carbon-neutral, and inclusive. Each one has its own limitations. Chetan Choudhury writes that the essence is simple: a city should be good to live in

Confronting the Evolving Safety and Security Challenge at Colleges and Universities

[Excerpt] “Colleges and universities have long been scrutinized and confronted with lawsuits regarding safety and security measures designed and implemented to protect students and prevent dangerous incidents on campus. Under the doctrine of in loco parentis, college administrators assume responsibility for the physical safety and well-being of students as they matriculate through their academic programs. However, in recent decades, the realization that university communities are not immune to criminal activity has led to federal legislation and judicial opinions that have attempted to identify what legal duty colleges and universities have to prevent security breaches. Moreover, college and university administrators have looked to the courts and legal counsel to determine an institution’s exposure to legal liability and strategies that might be used to minimize such exposure. This charge has been, and remains, a daunting challenge for the higher education community. This Article reviews recent cases regarding the legal duty American colleges and universities have to protect the student community from harm or injury resulting from safety or security breaches. Moreover, this Article identifies legal challenges colleges and universities may face in response to campus surveillance efforts and negligence hiring and retention allegations. Finally, the Article offers some insight intended to advance the legal community’s efforts to counsel and advise college and university administrators regarding the issue of campus safety.
