Mobile and Wireless Communications Networks ; IFIP TC6 / WG6.8 Conference on Mobile and Wireless Communication Networks (MWCN 2004) October 25-27, 2004 Paris, France
Mobile Ad hoc NETworks (MANETs) has attracted great research interest in recent years. A Mobile Ad Hoc Network is a self-organizing multi-hop wireless network where all hosts (often called nodes) participate in the routing and data forwarding process. The dependence on nodes to relay data packets for others makes mobile ad hoc networks extremely susceptible to various malicious and selfish behaviors. This point is largely overlooked during the early stage of MANET research. Many works simply assume nodes are inherently cooperative and benign. However, experiences from the wired world manifest that the reverse is usually true; and many works [3] [10] [9] [8] [12] [19] have pointed out that the impact of malicious and selfish users must be carefully investigated. The goal of this research is to address the cooperation problem and related security issues in wireless ad hoc networks. As a rule of thumb, it is more desirable to include security mechanisms in the design phase rather than continually patching the system for security breaches. As pointed out in [2] [1], there can be both selfish and malicious nodes in a mobile ad hoc network. Selfish nodes are most concerned about their energy consumption and intentionally drop packets to save power. The purpose of malicious nodes, on the other hand, is to attack the network using various intrusive techniques. In general, nodes in an ad hoc network can exhibit Byzantine behaviors.

Furthermore, this book provides an introduction to the fundamentals of MANETs, an overview of protocols for each layer of the protocol stack, and a discussion of the issues involved with energy-efficient protocol design and quality of service for real-time data transmission.
Mixed Hodge Structures
The text of this book has its origins more than twenty- ve years ago. In the seminar of the Dutch Singularity Theory project in 1982 and 1983, the second-named author gave a series of lectures on Mixed Hodge Structures and Singularities, accompanied by a set of hand-written notes. The publication of these notes was prevented by a revolution in the subject due to Morihiko Saito: the introduction of the theory of Mixed Hodge Modules around 1985. Understanding this theory was at the same time of great importance and very hard, due to the fact that it uni es many di erent theories which are quite complicated themselves: algebraic D-modules and perverse sheaves. The present book intends to provide a comprehensive text about Mixed Hodge Theory with a view towards Mixed Hodge Modules.
Mix-Design and Application of Hydraulic Grouts for Masonry Strengthening
Provides guidance for the rational design and application of hydraulic grouts, based on a series of specific data (type of masonry, voids' width, targeted strength and durability level, available materials, etc.). To this end, the basic characteristics of a grout, i.e. its injectability (penetrability, fluidity and stability), its strength and durability, are taken into account by means of rational models and quantified expressions of all grout-design parameters. Thus, a holistic, rational mix design methodology for optimization of grout composition is given, permitting the preliminary design of grouts, without having to resort to multiple tests in advance.
Mitral valve diseases
The heart is a pump consisting of 4 chambers:2 atria and 2 ventricles and 4 valves one of them is mitral valve which is located betweenthe left atrium and the left ventricle and prevents the backward flow of blood.Ithas several unique features: Mitral annulus, two leaflets, the chordae tendineaeand papillary muscles. The mitral valve may become stenotic or may regurgitate. Regurgitation(or leakage of the valve): When the valve (s) do not close completely. Stenosis (or narrowing of the valve): When the valve (s) opening becomes narrowed. Mitral stenosis is categorized as mild, moderate or severe it is typically causedby (Rheumatic fever, A congenital heart, Calcium deposits .....) and it caused severalsymptoms such as: dyspnea, hemoptysis, fatigue, Chest pain and others Where as the Signs and symptoms of mitral valve regurgitation, can include: Abnormal heart sound, Shortness of breath, Heart palpitations, Fatigue, edma, Coughing.
Misinterpretations about Covid-19 vaccines
Immunization has become a vital part of public health and disease prevention, yet remain Vaccination is the most effective medical intervention ever a controversial topic. introduced, it has eliminated a large part of the infectious diseases that once killed millions of people. Recently, a number of effective vaccines have been manufactured and proved to be effective against the virus, but a rising incidents was observed of refusing people to take COVID-19 (SARS-CoV-2) vaccine because of the wrong myths they hear about the vaccine or its existing and non-existing side effects. The purpose of this research is to clarify information and remove vagueness about the vaccines and definitively convert fake concepts into facts by answering questions in a scientific method.
Minimally Invasive Tumor Therapies
In the age of the World Wide Web, informed patients continue to surprise oncologists with detailed questions about popular tumor therapies. Although minimally invasive tumor therapies (MITT) have become daily clinical practice for palliative treatment of liver tumors, the acceptance of these palliative modalities still varies enormously. In addition, promising results have been published for in situ ablation of lung metastases, bone tumors, and renal cell carcinoma. This book gives an up-to-date overview of the popular techniques and clinical results of MITT, with a clarification of the actual indications including the size, tumor entities, and clinical benefits. Moreover, the book focuses on the prospectives and limitations of imaging methods - ultrasound, computed tomography, and magnetic resonance imaging - used for MITT.

Migrants and Expats : The Swiss Migration and Mobility Nexus
This book provides insight on current patterns of migration in Switzerland, which fall along a continuum from long-term and permanent to more temporary and fluid. These patterns are shaped by the interplay of legal norms, economic drivers and societal factors. The various dimensions of this Migration-Mobility Nexus are investigated by means of newly collected survey data: the Migration-Mobility Survey. The book covers different aspects of life in the host country, including the family dimension, the labour market and political participation as well as social integration. The book also takes into account the chronological dimension of migration by considering the migrants’ arrival, their stay, and their expectations regarding return.

Mid-infrared Semiconductor Optoelectronics
Mid-infrared Semiconductor Optoelectronics is an overview of the current status and technological development in this rapidly emerging area. It is composed of four parts. First, the basic physics and some of the main problems facing the design engineer (together with a comparison of possible solutions) are laid out. Next, there is a consideration of the multifarious lasers used as sources for mid-infrared technology, including an inspection of current approaches to the lack of such a source in the 3–4 µm region. Part III reviews recent work in light-emitting diodes and detectors and also deals with negative luminescence. The final part of the book is concerned with applications and highlights, once more, the diversity and technological importance of the mid-infrared spectral region.
Mid-Infrared Coherent Sources and Applications
Coherent sources of mid-infrared (mid-IR) radiation are of great interest for a wide range of scienti?c and technological applications from spectroscopy and frequency metrology to information technology, industrial process control, pho- chemistry, photobiology and photomedicine. The mid-IR spectrum, which may be de?ned as wavelengths beyond ?2µm, covers important atmospheric windows, and numerous molecular gases, toxic agents, air, water, and soil pollutants, c- ponents of human breath, and several explosive agents have strong absorption ?ngerprints in this region. The development of practical coherent solid-state sources in the mid-IR can thus provide indispensable tools for a variety of - plications in environmental monitoring and pollution control, detection of water and soil contaminants, food quality control, agriculture and life sciences, and n- invasive disease diagnosis and therapy through breath analysis.
