Various types of encoding transducers (encoders) are used in modern technics widely to measuring the characteristics of mechanical motion which is predetermined by their reliability, operation stability and some other positive qualities. At the same time the basic operation principle of this measuring transducers type determines the presence of irremovable methodological errors in the measurements results obtained with their help. These errors reduce the efficiency of target systems. Their accounting and further compensation are possible in the presence of the mathematical apparatus for simulation of the measurement results. In this article substantiation and synthesis of this apparatus which includes the main encoder’s parameters are carried out. The generated mathematical model can be used for the selection or design of encoding transducers to electronic monitoring and control systems for automobiles, tractors as well as other self-moving machines and technical objects at all.

A Company

An email system is a critical business tool and an essential part of organisational communication. Many organisations have experienced negative impacts from email and have responded by electronically monitoring and restricting email system use. However, electronic monitoring of email can be contentious. Staff can react to these controls by dissent, protest and potentially transformative action. This chapter presents the results of a single case study investigation of staff reactions to electronic monitoring and control of an email system in a company based in Ireland. The findings highlight the variations in staff reactions through multiple time frames of electronic monitoring and control, and the chapter identifies the key concerns of staff which need to be addressed by management and consultants advocating the implementation of email system monitoring and control.

Использование буксируемого поверхностного модуля радиосвязи (ПМР) позволяет организовать высокоскоростной канал связи поста управления с автономным подводным роботом (АПР), а также значительно упростить его навигационное обеспечение. При этом возмущения от кабеля связи, действующие на АПР и ПМР, будут в значительной степени влиять на характеристики движения такой привязной системы. В работе методами компьютерного моделирования исследуются силовые воздействия кабеля связи на буксировке, а также их влияние на движение аппарата в установившихся режимах и по типовым траекториям маневрирования. Для установившихся значений глубины погружения и скорости хода АПР определена длина кабеля связи, обеспечивающая минимальное силовое воздействие от буксировки на аппарат. Предложена комплексная модель системы управления движением подводной привязной системы, учитывающая динамику АПР и кабеля связи. Разработана кинематическая модель поведения ПМР, определяющая его заглубление и гидродинамическое сопротивление при буксировке. Приведены результаты моделирования движения привязной системы по типовым траекториям, характерным для обзорно-поисковых АПР, которые позволяют оценить дополнительные требования к тяговым характеристикам движительно-рулевого комплекса аппарата, а также к необходимому запасу плавучести ПМР. Utilization of the towed surface radiocommunication module (SRM) allows organizing a high-speed communication channel between the control station and autonomous underwater robot/autonomous underwater vehicle (AUR/AUV), as well as significantly simplify its navigation guidance support. Herewith, the disturbances from communication cable effects on AUV and SRM, and heavily influences the motion characteristics of such a tethered system. This paper studies force actions of communication wire on towage and its influence on vehicle motion along standard maneuvering trajectories in steady-state modes using computer modeling. The length of communication cable providing minimal force actions on the vehicle from towing was determined for steady values of submersion depth and movement speed of the AUV. The integrated model of the motion control system of the underwater tethered system was proposed taking into account the dynamic of AUV and communication cable. The kinematic model of SRM behavior was designed to determine its submersion depths and hydrodynamic resistance while being towed. Acquired and demonstrated results of the tethered system motion modeling along standard trajectories typical for search operations allow estimating additional requirements for thrust characteristics of the propulsion/steering unit of the vehicle, as well as the necessary buoyance reserve of the SRM.

In recent years, the number of surveillance cameras installed to monitor private and public spaces has increased rapidly. The demand has raised for smarter video surveillance of public and private spaces using intelligent vision systems which can differentiate between 'suspicious' and 'unsuspicious' behaviours according to the human observer. Generally, the video streams are constantly recorded or monitored by operators. In these cases, an intelligent system can give more accurate performance than a human. We have proposed a method called motion influence map under machine learning for representing human activities. Optical-flow is computed for each pixel in a frame that are processed sequentially. The key feature of the proposed motion influence map is that it effectively reflects the motion characteristics such as movement speed, movement direction, and size of the objects or subjects and their interactions within a frame sequence. It further extracts frames of high motion influence values and compares with the testing frames to automatically detect suspicious activities.

Abstract Denmark was the first nation in Europe to promote the use of Fully Documented Fisheries (FDF) through Remote Electronic Monitoring (REM) and CCTV camera systems, with pilot schemes in place since 2008. In theory, such a scheme could supplement and even potentially replace expensive control and monitoring programmes; and when associated with a catch quota management (CQM) system, incentivize positive changes in fishing patterns in a results-based management approach. New data flows are, however, required to ensure the practical implementation of such a scheme. This paper reviews the quality of the FDF data collected during 2008–2014 and their potential in strengthening information on cod discards. The analyses demonstrate the improved reporting of discards in logbooks and overall discard reductions, but they also show that some uncertainties around the absolute estimates of discard quantities have remained. Regular validation of weight estimation methods and close collaboration between scientific monitoring and control are important to support the use of reported discards as a reliable source of information. We discuss the potential of electronic monitoring in the context of the EU landing obligation.

Personal computers (PCs) are a powerful resource in the EM Laboratory, both as a means of automating the monitoring and control of microscopes, and as a tool for quantifying the interpretation of data. Not only is a PC more versatile than a piece of dedicated data logging equipment, but it is also substantially cheaper. In this tutorial the practical principles of using a PC for these types of activities will be discussed.The PC can form the basis of a system to measure, display, record and store the many parameters which characterize the operational conditions of the EM. In this mode it is operating as a data logger. The necessary first step is to find a suitable source from which to measure each of the items of interest. It is usually possible to do this without having to make permanent corrections or modifications to the EM.

The Central Nervous System

Dysphagia is common in patients with dementia. Dysphagia occurs as a result of changes in the sensory and motor function of the swallow (Easterling, 2007). It is known that the central nervous system can undergo experience-dependent plasticity, even in those individuals with dementia (Park & Bischof, 2013). The purpose of this study was to explore whether or not the use of neuroplastic principles would improve the swallow motor plan and produce positive outcomes of a patient in severe cognitive decline. The disordered swallow motor plan was manipulated by focusing on a neuroplastic principles of frequency (repetition), velocity of movement (speed of presentation), reversibility (Use it or Lose it), specificity and adaptation, intensity (bolus size), and salience (Crary & Carnaby-Mann, 2008). After five therapeutic sessions, the patient progressed from holding solids in her mouth with decreased swallow initiation to independently consuming a regular diet with full range of liquids with no oral retention and no verbal cues.
