Recent Trends in Communication Networks
In recent years there has been many developments in communication technology. This has greatly enhanced the computing power of small handheld resource-constrained mobile devices. Different generations of communication technology have evolved. This had led to new research for communication of large volumes of data in different transmission media and the design of different communication protocols. Another direction of research concerns the secure and error-free communication between the sender and receiver despite the risk of the presence of an eavesdropper. For the communication requirement of a huge amount of multimedia streaming data, a lot of research has been carried out in the design of proper overlay networks. The book addresses new research techniques that have evolved to handle these challenges
New advances in vehicular technology and automotive engineering
An automobile was seen as a simple accessory of luxury in the early years of the past
century. Therefore, it was an expensive asset which none of the common citizen could
afford. It was necessary to pass a long period and waiting for Henry Ford to establish
the first plants with the series fabrication. This new industrial paradigm makes easy to
the common American to acquire an automobile, either for running away or for
working purposes. Since that date, the automotive research grown exponentially to the
levels observed in the actuality. Now, the automobiles are indispensable goods; saying
with other words, the automobile is a first necessity article in a wide number of
aspects of living: for workers to allow them to move from their homes into their
workplaces, for transportation of students, for allowing the domestic women in their
home tasks, for ambulances to carry people with decease to the hospitals, for
transportation of materials, and so on, the list don’t ends. The new goal pursued by the
automotive industry is to provide electric vehicles at low cost and with high reliability.
This commitment is justified by the oil’s peak extraction on 50s of this century and also
by the necessity to reduce the emissions of CO2 to the atmosphere, as well as to reduce
the needs of this even more valuable natural resource. In order to achieve this task and
to improve the regular cars based on oil, the automotive industry is even more
concerned on doing applied research on technology and on fundamental research of
new materials. The most important idea to retain from the previous introduction is to
clarify the minds of the potential readers for the direct and indirect penetration of the
vehicles and the vehicular industry in the today’s life. In this sequence of ideas, this
book tries not only to fill a gap by presenting fresh subjects related to the vehicular
technology and to the automotive engineering but to provide guidelines for future
research.
This book account with valuable contributions from worldwide experts of
automotive’s field. The amount and type of contributions were judiciously selected to
cover a broad range of research. The reader can found the most recent and
cutting-edge sources of information divided in four major groups: electronics (power,
communications, optics, batteries, alternators and sensors), mechanics (suspension
control, torque converters, deformation analysis, structural monitoring), materials (nanotechnology, nanocomposites, lubrificants, biodegradable, composites, structural
monitoring) and manufacturing (supply chains).
We are sure that you will enjoy this book and will profit with the technical and
scientific contents. To finish, we are thankful to all of those who contributed to this
book and who made it possible.info:eu-repo/semantics/publishedVersio
Modern Telemetry
Telemetry is based on knowledge of various disciplines like Electronics, Measurement, Control and Communication along with their combination. This fact leads to a need of studying and understanding of these principles before the usage of Telemetry on selected problem solving. Spending time is however many times returned in form of obtained data or knowledge which telemetry system can provide. Usage of telemetry can be found in many areas from military through biomedical to real medical applications. Modern way to create a wireless sensors remotely connected to central system with artificial intelligence provide many new, sometimes unusual ways to get a knowledge about remote objects behaviour. This book is intended to present some new up to date accesses to telemetry problems solving by use of new sensors conceptions, new wireless transfer or communication techniques, data collection or processing techniques as well as several real use case scenarios describing model examples. Most of book chapters deals with many real cases of telemetry issues which can be used as a cookbooks for your own telemetry related problems
Control of Energy Storage
Energy storage can provide numerous beneficial services and cost savings within the electricity grid, especially when facing future challenges like renewable and electric vehicle (EV) integration. Public bodies, private companies and individuals are deploying storage facilities for several purposes, including arbitrage, grid support, renewable generation, and demand-side management. Storage deployment can therefore yield benefits like reduced frequency fluctuation, better asset utilisation and more predictable power profiles. Such uses of energy storage can reduce the cost of energy, reduce the strain on the grid, reduce the environmental impact of energy use, and prepare the network for future challenges. This Special Issue of Energies explore the latest developments in the control of energy storage in support of the wider energy network, and focus on the control of storage rather than the storage technology itself
Telecos Sense Fronteres: Pla de telecomunicacions per a la regió del Kukra River. Fase I.
Des de Telecos Sense Fronteres en aquest treball es pretén donar una solució
tècnica al problema de la incomunicació de diferents entitats mèdiques del
país de Nicaragua.
A la conca del Kukra River, riu de la regió de la RAAS de Nicaragua, hi viuen
diverses comunitats en situació molt precària. Una d’elles és La Aurora, l’única
que disposa d’un Puesto de Salud molt rudimentari per atendre les necessitats
de totes les comunitats. El personal sanitari d’aquesta comunitat ha de fer
viatges de fins a deu hores a peu, a cavall o en barca per arribar a les altres
comunitats o a un hospital amb recursos.
L’hospital més proper es troba a la ciutat de Bluefields, capital de la RAAS, a
unes vuit hores de navegació en barca.
Existeix un pla per al desenvolupament de la zona. La primera fase d’aquest
pla, comunicar l’hospital de Bluefields amb la comunitat de La Aurora, és
l’objecte d’aquest TFC.
Per tal d’aconseguir-ho s’han utilitzat les tecnologies Wi-Fi i VoIP. Es vol que
entre els dos emplaçaments es puguin fer trucades telefòniques,
videoconferències i transferència d’arxius (com ara referents a informació
epidemiològica). Aquests dos llocs estan separats per uns 33 quilòmetres
aproximadament però no gaudeixen de visibilitat directa. Per resoldre-ho s’ha
utilitzat un punt intermedi, el Cerro Aberdeen.
El treball, doncs, ha consistit en l’anàlisi del problema, la tria de les
tecnologies, el hardware i el software més adients, l’adquisició dels equips i el
posterior viatge a Nicaragua per a la seva implantació.
El disseny i les proves del sistema han estat satisfactoris però la implantació
no s’ha pogut realitzar completament per problemes burocràtics en l’enviament
dels equips
Recent Advances in Signal Processing
The signal processing task is a very critical issue in the majority of new technological inventions and challenges in a variety of applications in both science and engineering fields. Classical signal processing techniques have largely worked with mathematical models that are linear, local, stationary, and Gaussian. They have always favored closed-form tractability over real-world accuracy. These constraints were imposed by the lack of powerful computing tools. During the last few decades, signal processing theories, developments, and applications have matured rapidly and now include tools from many areas of mathematics, computer science, physics, and engineering. This book is targeted primarily toward both students and researchers who want to be exposed to a wide variety of signal processing techniques and algorithms. It includes 27 chapters that can be categorized into five different areas depending on the application at hand. These five categories are ordered to address image processing, speech processing, communication systems, time-series analysis, and educational packages respectively. The book has the advantage of providing a collection of applications that are completely independent and self-contained; thus, the interested reader can choose any chapter and skip to another without losing continuity
