Existen procedimientos químicos y físicos para evitar la infección microbiana de los alimentos. Entre los químicos tenemos la adición de conservantes al alimento, que inhiben el desarrollo microbiano. Entre los fisicos tenemos el frio que tambien inhibe el desarrollo microbiano de una forma mas natural. De ahi la importancia de la cadena de frio en la distribucion y almacenamiento de los alimentos. Es preciso disponer de buenos equipos (frigorificos, congeladores, vitrinas, etc.). Tambien es muy importante el manejo higienico de los alimentos. Actualmente se desarrollan contratos de mantenimiento que, por lo general, se hacen por un año y permiten al empresario descargar las tareas dirigidas al riguroso mantenimiento y averias en favor del instalador frigorista. Un contrato de mantenimiento, no quiere decir que no se produzcan averias, pero estas disminuyen en un porcentaje muy alto. Siempre esto es mejor que decir yo llamo cuando se produzca la averia. Ocurre que cuando se producen las averias, (generalmente al principio del verano), tambien le ocurre a mas equipos y muebles frigorificos y se tarda en acudir para solucionar dicha averia, debido a la gran demanda de avisos por averias. Este libro sirve para tener un buen conocimiento sobre los fallos en compresores hermeticos instalados en infinidad de frigorificos electrodomesticos, botelleros, enfriadores de cerveza, en la hosteleria, vitrinas expositoras en tiendas, etc. Va dirigido, sobre todo, a reparadores de muebles frigorificos y electrodomesticos, a estudiantes de Formacion Profesional, fabricantes de electrodomesticos y muebles frigorificos en general y a todo tecnico relacionado con el sector. Se estudian compresores 220/240 50 Hz/60Hz. Tambien termostatos de servicio para instalar en los diversos muebles frigorificos (con distintos desescarches, con/sin señalizacion, regulador electronico, etc.). Se parte de la base que, en un principio, los muebles frigorificos estan bien fabricados y todos sus elementos en principio funcionan correctamente. Es un libro muy practico y sencillo para llevar un correcto mantenimiento en el frio y refrigeracion comercial.

Anyone who has experienced turbulence in flight knows that it is usually not pleasant, and may wonder why this is so difficult to avoid. The book includes papers by various aviation turbulence researchers and provides background into the nature and causes of atmospheric turbulence that affect aircraft motion, and contains surveys of the latest techniques for remote and in situ sensing and forecasting of the turbulence phenomenon. It provides updates on the state-of-the-art research since earlier studies in the 1960s on clear-air turbulence, explains recent new understanding into turbulence generation by thunderstorms, and summarizes future challenges in turbulence prediction and avoidance.

This monograph is an exposition of a novel method for solving inverse problems, a method of parameter estimation for time series data collected from simulations of real experiments. These time series might be generated by measuring the dynamics of aircraft in flight, by the function of a hidden Markov model used in bioinformatics or speech recognition or when analyzing the dynamics of asset pricing provided by the nonlinear models of financial mathematics. Dynamic Systems Models demonstrates the use of algorithms based on polynomial approximation which have weaker requirements than already-popular iterative methods. Specifically, they do not require a first approximation of a root vector and they allow non-differentiable elements in the vector functions being approximated. The text covers all the points necessary for the understanding and use of polynomial approximation from the mathematical fundamentals, through algorithm development to the application of the method in, for instance, aeroplane flight dynamics or biological sequence analysis. The technical material is illustrated by the use of worked examples and methods for training the algorithms are included. Dynamic Systems Models provides researchers in aerospatial engineering, bioinformatics and financial mathematics (as well as computer scientists interested in any of these fields) with a reliable and effective numerical method for nonlinear estimation and solving boundary problems when carrying out control design. It will also be of interest to academic researchers studying inverse problems and their solution.

This book introduces several observer-based methods, including: the sliding-mode observer the adaptive observer the unknown-input observer and the descriptor observer methodfor the problem of fault detection, isolation and estimation, allowing readers to compare and contrast the different approaches. The authors present basic material on Lyapunov stability theory, H control theory, sliding-mode control theory and linear matrix inequality problems in a self-contained and step-by-step manner. Detailed and rigorous mathematical proofs are provided for all the results developed in the text so that readers can quickly gain a good understanding of the material. MATLAB and Simulink codes for all the examples, which can be downloaded from http://extras.springer.com, enable students to follow the methods and illustrative examples easily. The systems used in the examples make the book highly relevant to real-world problems in industrial control engineering and include a seventh-order aircraft model, a single-link flexible joint robot arm and a satellite controller. To help readers quickly find the information they need and to improve readability, the individual chapters are written so as to be semi-independent of each other.Robust Oberserver-Based Fault Diagnosis for Nonlinear Systems Using MATLAB is of interest to process, aerospace, robotics and control engineers, engineering students and researchers with a control engineering background.

Spacecraft and Payload Pointing focuses on development of the attitude determination and control system (ADACS) for a spacecraft, including payload pointing. Such systems can require knowledge of a large diversity of disciplines for two reasons. First, the ADACS itself is a broad subject, including the dynamics of the spacecraft and payloads, the physics and engineering of the ADACS sensor and actuator hardware, control and filtering theory, plus systems engineering. Second, many disciplines are involved since the ADACS must interface with several other subsystems (notably payload, structure, and command and data handling [C&DH]) and because ADACS performance translates into key mission performance parameters such as pointing control. When mission requirements are flowed down to the spacecraft and then to its subsystems, the engineer must be able to translate these requirements into appropriate terms at each level.Mission requirements are customer related (such as the ability to broadcast a TV signal or transmit data); they must be translated into spacecraft system concepts (orbits, transmitted power levels), then to subsystem requirements (available power, antenna gain, antenna pointing accuracy), and further down to the level of components. Rather than treat each of the subject areas involved in ADACS design in great depth, this book aims to show how they fit together. The subject can be examined from two basic points of view. The first is that of the systems engineer. This view focuses on requirements, requirements flowdowns, and verification. In it, the onboard hardware and software are regarded as black boxes, defined by their functions, reliability, etc. The other standpoint is that of the physicist or engineer who focuses on what is involved in actually getting these items to work. This view includes actions such as quantifying feasible performance levels, learning how they can be improved, and understanding their fundamental

The Principles and Practice of International Aviation Law provides an introduction to, and demystification of, the private and public dimensions of international aviation law. Unlike other global sectors, the air transport industry is not governed by a discrete area of the law, but by disparate transnational regulatory instruments. Everything from the routes that an international air carrier can serve to the acquisition of its fleet and its liability to passengers and shippers for incidents arising from its operations can be the object of bilateral and multilateral treaties that represent diverse and often contradictory interests. Beneath this are hundreds of domestic regulatory regimes that also apply national and international rules in disparate ways. The result is an agglomeration of legal cultures that can leave even experienced lawyers and academics perplexed. By combining classical doctrinal analysis with insights from newer disciplines such as international relations and economics, the book maps international aviation law's complex terrain for new and veteran observers alike
