When considering the main trends in the development of modern autonomous objects (aircraft, combat vehicles, motor vehicles, floating vehicles, agricultural machines, etc.) in recent decades, two key areas can be identified. The first direction is associated with the improvement of traditional designs of autonomous objects (AO) with an internal combustion engine (ICE) or a gas turbine engine (GTD). The second direction is connected with the creation of new types of joint-stock companies, namely electric joint-stock companies( EAO), joint-stock companies with combined power plants (AOKEU).
 The energy efficiency is largely determined by the power of the generator set and the battery, which is given to the electrical network in various driving modes.
 Most of the existing methods for calculating power supply systems use the average values of disturbing factors (generator speed, current of electric energy consumers, voltage in the on-board network) when choosing the characteristics of the generator set and the battery. At the same time, it is obvious that when operating a motor vehicle, these parameters change depending on the driving mode. Modern methods of selecting the main parameters and characteristics of the power supply system do not provide for modeling its interaction with the power unit start-up system of a motor vehicle in operation due to the lack of a systematic approach.
 The choice of a generator set and a battery, as well as the concept of the synthesis of the power supply system is a problem studied in the monograph.
 For all those interested in electrical engineering and electronics.

The monograph presents organizational and technological solutions for the technical re-equipment of industrial housing construction enterprises, taking into account the totality of operating production conditions, the methodology for assigning reserves of production capacities for the production of a wide range of products and changing demand for products, and production optimization solutions. The organizational and technological solutions for the development of the production base of industrial housing construction based on flexible production technology are considered in detail. For the first time, methods have been developed to improve the technological level of industrial housing construction enterprises without stopping the main production. The dependence of the production capacity of enterprises on the parameters of the product range has been established. The recommendations of assigning reserves to the production capacity of enterprises in the context of the production of a wide range of products and changes in demand for products are substantiated. The optimization of production was carried out by ensuring the rhythm of production based on the criteria of complexity of products in the nomenclature of the production program of enterprises. It will be useful for specialists to make design, organizational and managerial decisions for the production of basic types of flat precast concrete products at industrial housing construction enterprises.

The Thesis focuses on Smectic-A (SmA) liquid crystals' (LCs) functional behaviour in order to understand if this will be the next generation product that could improve the daily life of the society. The optical properties of this liquid crystal are by far the best compared to the products available in the market, i.e., the light transmittance in transparent state is >85 % and in scatter state <2 %. Enabling the LC to be used for a variety of purposes, such as smart windows to scatter light on a sunny day or provide a sense of privacy in an open type office space. An in-depth literature review discusses the existing studies, obtained experimental data and attempts to develop functional products. The main unresolved problems are highlighted, described in detail and solutions are offered. In order to understand the potential of SmA LC in the smart glass/window technology, analysis of existing products was performed, a summary of an active smart glass/windows provided, and a comparative study between them was made. In addition, an in-depth study of long-term functional stability was performed during which the most popular types of defects were listed and analysed. Solutions for defect elimination and recommendations for optimization of switching systems and production processes are provided. A methodology for determining the electrical parameters of an LC has been developed in order to create an electrical simulation model and facilitate the development of electronic switching systems.

Several radical groups—particularly Anabaptists and Spiritualists—in Wittenberg, Zurich, and Strasbourg proffered different performances of prophecy that emphasized its visionary, ecstatic forms and even affirmed the possibility of new revelation above and beyond Scripture. Luther, Zwingli, and Bucer responded to Andreas Karlstadt, Gabriel Zwilling, the Zwickau Prophets, Thomas Müntzer, Swiss Anabaptists, Melchior Hoffman, Balthasar Hubmaier, Hans Denck, Caspar Schwenckfeld, and Pilgram Marpeck by casting many of them as false prophets and often lumped them together under their most extreme forms rather than recognizing the variations among them. Radical groups differed on the topic of prophecy: some prioritized Scripture, while others prioritized the Spirit. Luther and Zwingli reframed their view of the prophet and prophecy in direct response to these radical threats to tighten the parameters of lay participation and identify the prophet more closely with the Protestant pastoral office.

The pragmatic aspects of all steps involved in establishing an integrated psychiatry (and other mental health) care model in a HIV outpatient clinic are discussed in detail in this chapter. These include initial outreach inquiry, interdepartmental discussion, business case analysis, logistics in establishing clinical routines and operating relationships, utilization management, information technology, and research and educational opportunities specific to this model of collaborative care. The beneficial aspects of integrated care include increased engagement and retention in HIV care and decreased HIV morbidity and mortality. A biopsychosocial approach provides a model for compassionate and multidimensional care. Readers are encouraged to apply this framework within the parameters of their local institutions when establishing integrated psychiatric care models in HIV clinics.

Scope This NACE standard describes a variety of devices used for on-line monitoring of fouling, corrosion, and other parameters in recirculating cooling tower water systems. Methods are presented for collecting test data to determine fouling and corrosion rates that can be used for, but are not limited to, (1) predicting the expected service life of heat-exchange equipment, (2) optimizing the cooling system operation, (3) detecting operating problems and upset conditions, (4) monitoring corrective actions taken when such conditions occur, (5) assisting in problem solving, and (6) evaluating alternate chemical treatment programs. This standard is intended for the use of operators of open recirculating cooling water systems and those organizations that supply treatment materials and consulting services to them. This standard was originally prepared in 1989 by NACE Task Group T-3T-1, a component of Unit Committee T-3T on On-Line Monitoring Technology, and revised in 1995 by T-3T-4. It was revised in 2002 by NACE Task Group (TG) 241 on On-Line Monitoring of Cooling Waters and Cooling Water Test Units. TG 241 is administered by Specific Technology Group (STG) 11 on Water Treatment. This standard was issued by NACE International under the auspices of STG 11. The purpose of this standard is to describe technologies applicable to the on-line monitoring of cooling water systems. The standard focuses on those technologies that provide data on a short-term basis (minutes to hours) and provide output in a form that may be used by the operator to deal with changing conditions in real time. For the purpose of this standard, an on-line monitor for a cooling water system is defined as a device, or combination of devices, that measures corrosion rates and determines changes in heat transfer coefficients (fouling factors) by measuring pertinent parameters under steady-state conditions that simulate critical conditions in an operating heat exchanger in a reliable and objective manner and with acceptable precision and accuracy. (Nomenclature and abbreviations used in this standard are defined in Appendix A.).

This comprehensive study examines the case of AM stereo and subsequent technologies to demonstrate the FCC's evolution from stern to reluctant regulator. It also examines emerging technologies, such as multichannel television sound, digital audio broadcasting, and high definition television, and discusses their impact on the evolution of broadcast regulation. In the 1980s the tension between governmental control and the marketplace resulted in the FCC's deregulation of TV and radio, electing to set only technical operating parameters and allowing legal operation of any system that meets those minimal standards. Huff argues that this approach is likely to influence regulatory approaches to other new developments in broadcast technologies. The extensive overview of the industry and the study of the interrelationships between the technologies will appeal to communication scholars in the fields of radio and television as well as interest industry professionals.

This book explores the phenomenon of ‘suicide tourism’. Freedom of movement creates problems with policies constrained by national boundaries and, as more countries contemplate regulating assisted suicide, there is now a pressing need for a theoretical investigation of the issues that provides a thorough appraisal of the global situation. Switzerland is no longer the only country where a person can find assistance for legal suicide. A similar law has been passed in Croatia, and Dutch and Belgian laws do not prohibit assisted suicide for non-residents. Few states in the US provide for physician-assisted suicide for state residents but US citizens from elsewhere can take simple steps to overcome this restriction. As more countries legally permit assisted suicide, suicide tourism will become a larger and more complex global practice. The book sets out the parameters for future debate, first contextualizing the practice and casting light on how it is treated under international and domestic law. It then analyses the ethical ramifications, and considers where the state’s responsibility should lie in dealing with accompanying persons and in regulating contractual agreements. It also contains a sociological and cultural analysis of suicide tourism, a review of policy and media reports on the topic, and interviews with various stakeholders (including policymakers, and medical and patients’ organizations) in Switzerland, Germany, France, Italy, and the UK. The book concludes with a summary of the legal, ethical, political, and sociological dimensions of suicide tourism, offering recommendations for how professionals and policymakers might respond to this evolving phenomenon.

Due to the complex nature of machinery and equipment used in the power industry, it is necessary for students at technical universities to become familiar not only with the theoretical aspects of the design and operation of these devices, but also with the measurement of process variables and their correct interpretation. Therefore, the students of the Department of Energy Machinery at the Faculty of Mechanical Engineering of the Slovak Univeristy of Technology in Bratislava are introduced to the measurement technique and principles of measuring the operating parameters of machinery and equipment, not only in the field of thermal power engineering, but also in the field of hydropower engineering, pumping technology and fluid power, from the bachelor's degree onwards. For this reason, this textbook has been created, in which students can learn both the basics of planning experiments, but also less conventional experimental methods or the use of experimental in the verification of mathematical models.

Brains as Engines of Association seeks an operating principle of the human brain and is divided into four parts. The first part (“What Nervous Systems Do for Animals”) is intended to set the stage for understanding the emergence of neural systems as promoting what all organisms must accomplish: survival and reproduction. The second part (“Neural Systems as Engines of Association”) lays out the general argument that biological sensing systems face a daunting problem: they cannot measure the parameters of the world in the way physical instruments can. As a result, nervous systems must make and update associations (synaptic connections) on the basis of empirical success or failure over both evolutionary and individual time. The third part (“Evidence that Neural Systems Operate Empirically”) reviews evidence accumulated over the past 20 years that supports this interpretation in vision and audition, the sensory systems that have been most studied from this or any other perspective. Finally, the fourth part (“Alternative Concepts of Neural Function”) considers the pros and cons of other interpretations of how brains operate. The overarching theme is that the nervous systems of humans and every other animal operate on the basis associations between stimuli and behavior made by trial and error over species and lifetime experience.

Medical Ventilator System Basics: A clinical guide—unlike books that focus on clinical applications, or that provide specifics about individual ventilator models, this is a practical guide about the equipment used for positive pressure mechanical ventilation. This book provides the information a clinician needs every day: how to assemble a ventilator system, how to determine appropriate ventilator settings, how to make sense of monitored data, how to respond to alarms, and how to troubleshoot ventilation problems. The book applies to all ventilators based on the intermittent positive pressure ventilation (IPPV) operating principle. In a systematic and comprehensive way, the book steps the user through the ventilator system, starting with its pneumatic principles to an explanation of the anatomy and physiology of respiration. It describes the system components, including the ventilator, breathing circuit, humidifier, and nebulizer. The book then introduces ventilation modes, starting with an explanation of the building blocks of breath variables and breath types. It describes the major ventilator functions, including control parameters, monitoring, and alarms. Along the way the book provides much practical troubleshooting information. Clearly written and generously illustrated, the book is a handy reference for anyone involved with mechanical ventilation, clinicians and non-clinicians alike. It is suitable as a teaching aid for respiratory therapy education and as a practical handbook in clinical practice.

Hard coal mining is characterised by features that pose numerous challenges to its current operations and cause strategic and operational problems in planning its development. The most important of these include the high capital intensity of mining investment projects and the dynamically changing environment in which the sector operates, while the long-term role of the sector is dependent on factors originating at both national and international level. At the same time, the conditions for coal mining are deteriorating, the resources more readily available in active mines are being exhausted, mining depths are increasing, temperature levels in pits are rising, transport routes for staff and materials are getting longer, effective working time is decreasing, natural hazards are increasing, and seams with an increasing content of waste rock are being mined. The mining industry is currently in a very difficult situation, both in technical (mining) and economic terms. It cannot be ignored, however, that the difficult financial situation of Polish mining companies is largely exacerbated by their high operating costs. The cost of obtaining coal and its price are two key elements that determine the level of efficiency of Polish mines. This situation could be improved by streamlining the planning processes. This would involve striving for production planning that is as predictable as possible and, on the other hand, economically efficient. In this respect, it is helpful to plan the production from operating longwalls with full awareness of the complexity of geological and mining conditions and the resulting economic consequences. The constraints on increasing the efficiency of the mining process are due to the technical potential of the mining process, organisational factors and, above all, geological and mining conditions. The main objective of the monograph is to identify relations between geological and mining parameters and the level of longwall mining costs, and their daily output. In view of the above, it was assumed that it was possible to present the relationship between the costs of longwall mining and the daily coal output from a longwall as a function of onerous geological and mining factors. The monograph presents two models of onerous geological and mining conditions, including natural hazards, deposit (seam) parameters, mining (technical) parameters and environmental factors. The models were used to calculate two onerousness indicators, Wue and WUt, which synthetically define the level of impact of onerous geological and mining conditions on the mining process in relation to: —— operating costs at longwall faces – indicator WUe, —— daily longwall mining output – indicator WUt. In the next research step, the analysis of direct relationships of selected geological and mining factors with longwall costs and the mining output level was conducted. For this purpose, two statistical models were built for the following dependent variables: unit operating cost (Model 1) and daily longwall mining output (Model 2). The models served two additional sub-objectives: interpretation of the influence of independent variables on dependent variables and point forecasting. The models were also used for forecasting purposes. Statistical models were built on the basis of historical production results of selected seven Polish mines. On the basis of variability of geological and mining conditions at 120 longwalls, the influence of individual parameters on longwall mining between 2010 and 2019 was determined. The identified relationships made it possible to formulate numerical forecast of unit production cost and daily longwall mining output in relation to the level of expected onerousness. The projection period was assumed to be 2020–2030. On this basis, an opinion was formulated on the forecast of the expected unit production costs and the output of the 259 longwalls planned to be mined at these mines. A procedure scheme was developed using the following methods: 1) Analytic Hierarchy Process (AHP) – mathematical multi-criteria decision-making method, 2) comparative multivariate analysis, 3) regression analysis, 4) Monte Carlo simulation. The utilitarian purpose of the monograph is to provide the research community with the concept of building models that can be used to solve real decision-making problems during longwall planning in hard coal mines. The layout of the monograph, consisting of an introduction, eight main sections and a conclusion, follows the objectives set out above. Section One presents the methodology used to assess the impact of onerous geological and mining conditions on the mining process. Multi-Criteria Decision Analysis (MCDA) is reviewed and basic definitions used in the following part of the paper are introduced. The section includes a description of AHP which was used in the presented analysis. Individual factors resulting from natural hazards, from the geological structure of the deposit (seam), from limitations caused by technical requirements, from the impact of mining on the environment, which affect the mining process, are described exhaustively in Section Two. Sections Three and Four present the construction of two hierarchical models of geological and mining conditions onerousness: the first in the context of extraction costs and the second in relation to daily longwall mining. The procedure for valuing the importance of their components by a group of experts (pairwise comparison of criteria and sub-criteria on the basis of Saaty’s 9-point comparison scale) is presented. The AHP method is very sensitive to even small changes in the value of the comparison matrix. In order to determine the stability of the valuation of both onerousness models, a sensitivity analysis was carried out, which is described in detail in Section Five. Section Six is devoted to the issue of constructing aggregate indices, WUe and WUt, which synthetically measure the impact of onerous geological and mining conditions on the mining process in individual longwalls and allow for a linear ordering of longwalls according to increasing levels of onerousness. Section Seven opens the research part of the work, which analyses the results of the developed models and indicators in individual mines. A detailed analysis is presented of the assessment of the impact of onerous mining conditions on mining costs in selected seams of the analysed mines, and in the case of the impact of onerous mining on daily longwall mining output, the variability of this process in individual fields (lots) of the mines is characterised. Section Eight presents the regression equations for the dependence of the costs and level of extraction on the aggregated onerousness indicators, WUe and WUt. The regression models f(KJC_N) and f(W) developed in this way are used to forecast the unit mining costs and daily output of the designed longwalls in the context of diversified geological and mining conditions. The use of regression models is of great practical importance. It makes it possible to approximate unit costs and daily output for newly designed longwall workings. The use of this knowledge may significantly improve the quality of planning processes and the effectiveness of the mining process.

This chapter summarizes current best practice with respect to intermittent haemodialysis and sustained low-efficiency dialysis (SLED) for those with acute kidney injury. These modalities can be delivered using a variety of technology platforms. These platforms for the most part use online dialysate, and water quality needs to be monitored and maintained to current standards. Intermittent haemodialysis and SLED provide reasonable outcomes in experienced hands, and ameliorate morbidity and mortality resulting from the ‘acute uraemic syndrome’: that is, intractable infection, non-resolving shock, and haemorrhage.Careful consideration needs to be given to appropriate modality selection for patients. Lower-efficiency modalities such as continuous therapies or SLED are more appropriate for patients at risk from dialysis disequilibrium syndrome, those with abdominal compartment syndrome, and those who are haemodynamically unstable (including cardiogenic shock). Care should be taken to avoid complications related to rapid fluid and solute removal, anticoagulation, and vascular access. Intradialytic hypotension is detrimental for both general and renal recovery of critically ill patients, and can be mitigated by sodium and ultrafiltration profiling, and frequent treatments and prolonged treatment time to minimize ultrafiltration goals and rates.Irrespective of the modality applied, an adequate dialysis dose must be achieved. This is facilitated through the use of optimally placed and technically superior central venous catheters, and well-considered prescription of haemodialysis and SLED operating parameters. Dose should be monitored regularly through urea kinetic modelling, either using Kt/V for thrice-weekly schedules or the corrected equivalent renal urea clearance (EKRc) for more frequent ones.

This book deals with the field of Electroencephalography in the widest possible sense, from the cellular foundations of the electric activities of the brain to a vast number of clinical applications. The basic science sections were up-dated to include advanced computer modeling approaches. The chapters on normal and pathological EEG findings in premature infants, newborns and children were thoroughly revised to keep up with the advances that have taken place recently in studying brain developmental issues. Major advances have taken place in neurophysiological findings in a variety of neurodegenerative disorders, which led to thoroughly revised chapters. Other rapidly changing subjects related to EEG recording/monitoring in ICU's, EMUs, and operating rooms, in patients with epilepsy, head injuries, infectious disorders and those undergoing surgical procedures, led to radically updating a number of chapters and to the addition of a chapter dedicated to invasive recordings for the treatment of patients with movement disorders. A previously missing chapter on the neurophysiology of myoclonus was added. Chapters that deal with automated EEG interpretation techniques and with standardizing EEG reporting using ILAE/IFCN approved terminology, were also added. Many chapters in the on-line version of the book will have the ability to link to a database of over 150 complete EEGs that cover the scope seen in a general EEG Lab. This link will allow the reader to manipulate the EEG display parameters as if they were in their own lab, generate a report and compare it to one generated by a panel of senior EEGers.
