Antennas for small mobile terminals
Digital Video Broadcasting for Handheld Terminals (DVB-H) is a service based
on DVB-T (for terrestrial broadcasting). Some differences and changes must
be considered to adapt the existing DVB-T technology to the experimental
DVB-H one. The purpose of this master thesis is to design the best possible
antenna for DVB-H. In order to achieve this, some scenarios are considered
such as the influence of the human hand and wood or metal planes (emulating
tables).
As this antenna must be inside a handheld device, its size will be a very limiting
factor. This is worsen by the fact that the wavelength is bigger than the size of
the handheld device and so this constraint will add more problems related with
small bandwidth, impedance matching, received power, etc.
Thanks to the simulations, two planar monopole antennas have been chosen
and explained in detail under the different scenarios. It will be seen that these
two antennas are small enough to fit in a handheld device and that they can
overcome all the problems related with the wavelength, received power, human
body interference, etc
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

Myxobacteria
Myxobacteria are fascinating and important prokaryotes. They have large genomes and exhibit a wide range of interesting behaviors, including multicellular fruiting body formation, social interaction, predation, and secondary metabolite production. Substantial progress is being made in understanding their ecological roles and the evolutionary forces that have shaped their phenotypes and behaviors. Novel species of myxobacteria are regularly described, often producing unusual metabolites and enzymes which can be of significant biotechnological interest. Molecular studies, ranging in subject from individual enzymes to entire ‘omes, continue to provide rich insights into myxobacterial biology. This collected volume brings together five research articles and three reviews, to provide a snapshot of current myxobacterial research in all its diversity
Using MapReduce Streaming for Distributed Life Simulation on the Cloud
Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp

Additionally, the book discusses the potential uses of these nanomaterials in photodetectors, transistors, quantum technology, chemical sensors, energy storage, silk fibroin, composites, drug delivery, tissue engineering, and sustainable agriculture and environmental applications
A Tale of Reciprocity: Minority Foundations in Greece and Turkey
The word most frequently uttered by Greece and Turkey with regard to their Muslim1 and non-Muslim minorities, respectively, is most probably ‘reciprocity.’ For more than half a century, in both countries, virtually all administrations,irrespective of their political leanings and ideological base, resorted to the good old ‘reciprocity argument’ to legitimize their laws, policies, and practices restricting the minority rights of Muslim and non-Muslim communities.
Both states have for decades justified their policies on the basis of a theory that argues that Article 45 of the 1923 Treaty of Lausanne provided the legal basis for reciprocity. Deliberately distorting a crystal-clear provision, which simply confers parallel obligations on Greece and Turkey for the protection of the Muslim and non-Muslim minorities, respectively, both states have for decades held their own citizens hostage, pitting them against each other in the name of defeating the other in foreign policy. Disregarding the objections of international lawyers and institutions that the reciprocity principle does not apply to human rights treaties and that states cannot condition the protection of the fundamental rights of their citizens on the policies of other states, both Greece and Turkey have successfully manipulated their national
public opinion into believing in the legitimacy of treating minorities as lesser citizens. This report analyzes the implications of reciprocity policies on the day-to-day lives of Muslim and
non-Muslim minorities in Greece and Turkey, specifically their impact on the community foundations2 belonging to these minorities. With a specific focus on the property and self-management issues of Muslim and non-Muslim community foundations in Greece and Turkey, the report situates the issue in its historical context and trace the evolution of the ‘community foundation issue’ from Lausanne to the present day. Drawing similarities and differences between the laws, policies, and practices of Greek and Turkish states vis-à -vis their minority foundations, the report critically assesses the progress made to this day as well as identify the outstanding issues
