Vehicle Propulsion Systems : Introduction to Modeling and Optimization ; 2nd ed.
Automobiles are responsible for a substantial part of the world's consumption of primary energy, mostly fossil liquid hydrocarbons. The reduction of the fuel consumption of these vehicles has become a top priority. Many ideas to reach that objective have been presented. In most cases these systems are more complex than the traditional approaches. For such complex systems a heuristic design approach fails. The only way to deal with this situation is to employ model-based methods. This text provides an introduction to the mathematical modeling and subsequent optimization of vehicle propulsion systems and their supervisory control algorithms.
Vehicle Dynamics and Control
Vehicle Dynamics and Control provides a comprehensive coverage of vehicle control systems and the dynamic models used in the development of these control systems.
VEGF in Development
This book is devoted to vascular endothelial growth factor A (VEGF or VEGFA), a secreted signalling protein of great significance for development and disease in vertebrates. VEGFA controls the proliferation, migration, specialisation and survival of vascular endothelial cells, and it is therefore essential for the establishment of a functional blood vessel circuit. In addition, VEGFA is emerging as a versatile patterning factor for several non-endothelial cell types in vertebrates. Thus, it plays a central role during organ development at multiple levels, including blood vessel growth, vessel-mediated organ induction and tissue differentiation.
Vegetative powers : The roots of life in ancient, medieval and early modern natural philosophy
The volume analyzes the natural philosophical accounts and debates concerning the vegetative powers, namely nutrition, growth, and reproduction. While principally focusing on the early modern approaches to the lower functions of the soul, readers will discover the roots of these approaches back to the Ancient times, as the volume highlights the role of three strands that help shape the study of life in the Medieval and early modern natural philosophies. From late antiquity to the early modern period, the vegetative soul and its cognate concepts have played a substantial role in specifying life, living functions, and living bodies, sometimes blurring the line between living and non-living nature, and, at other moments, resulting in a strong restriction of life to a mechanical system of operations and powers. Unearthing the history of the vegetative soul as a shrub of interconnected concepts, the 24 contributions of the volume fill a crucial gap in scholarship, ultimately outlining the importance of vegetal processes of incessant proliferation, generation, and organic growth as the roots of life in natural philosophical interpretations.
Vegetables II : Fabaceae, Liliaceae, Solanaceae, and Umbelliferae
The production and consumption of vegetables has expanded dramatically in the last years, with a global growth in the production of more than 50% in the last decade and it is expected that in the coming years, vegetable crops production will continue its expansion. The vegetables seed market is very dynamic and competitive, and predominant varieties are quickly replaced by new varieties. Therefore, updated information on the state of the art of the genetic improvement of specific crops is of interest to vegetable crops breeders, researchers and scholars. During the last years an immense quantity of new knowledge on the genetic diversity of vegetables and the utilization of genetic resources, breeding methods and techniques, and on the development and utilization of modern biotechnologies in vegetables crop breeding has accumulated, and there is a need of a major reference work that synthesizes this information.

Vector Semantics
Links the formal theory of word vectors to the cognitive theory of linguistics. The computational linguists and deep learning researchers who developed word vectors have relied primarily on the ever-increasing availability of large corpora and of computers with highly parallel GPU and TPU compute engines, and their focus is with endowing computers with natural language capabilities for practical applications such as machine translation or question answering. Cognitive linguists investigate natural language from the perspective of human cognition, the relation between language and thought, and questions about conceptual universals, relying primarily on in-depth investigation of language in use.
Vector Optimization : Set-valued and Variational Analysis
Vector optimization model has found many important applications in decision making problems such as those in economics theory, management science, and engineering design (since the introduction of the Pareto optimal solu tion in 1896). Typical examples of vector optimization model include maxi mization/minimization of the objective pairs (time, cost), (benefit, cost), and (mean, variance) etc. Many practical equilibrium problems can be formulated as variational in equality problems, rather than optimization problems, unless further assump tions are imposed. The vector variational inequality was introduced by Gi- nessi (1980). Extensive research on its relations with vector optimization, the existence of a solution and duality theory has been pursued. The fundamental idea of the Ekeland's variational principle is to assign an optimization problem a slightly perturbed one having a unique solution which is at the same time an approximate solution of the original problem. This principle has been an important tool for nonlinear analysis and optimization theory. Along with the development of vector optimization and set-valued optimization, the vector variational principle introduced by Nemeth (1980) has been an interesting topic in the last decade
Vector Control of Three-Phase AC Machines : System Development in the Practice
This monograph covers the area of vector control of three-phase AC machines, in particular induction motors with squirrel-cage rotor (IM), permanent excited synchronous motors (PMSM) and doubly-fed induction machines (DFIM), from the viewpoint of the practical design and development. Main focus is on the application of the IM and the PMSM in electrical drive systems, where the method of the field-orientated control has been successfully established in the practice, and on the use of the grid voltage orientated controlled DFIM in the wind power plants.
Vasculogenic mimicry : Methods and protocols
Provides detailed protocols for the identification and understanding of vasculogenic mimicry process in vitro and in vivo, in addition to protocols for microscopy and histology. Chapters guide readers through different materials, commercial and homemade scaffolds, Matrigel, cancer spheroids, 3D tissue constructs, vasculogenic processes, and mathematical model building.
Vascular Surgery
Proper management of vascular diseases is dependent on public awareness and appropriate training of specialists. Tis stands true for every medical d- cipline. For vascular surgery it has an additional aspect because, besides the required above-average standard of technical dexterity, the vascular surgeon should also be well versed in a variety of subjects such as molecular biology, in the use of ultrasound and – with the introduction of endovascular techniques – a skilful operator of guidewires and laparoscopic instruments. All the ac- mulated know-how and skills required for proper management of the vascular patient demand a rapid change in the training of vascular surgeons and an - depth knowledge of the various manifestations of vascular diseases.
Vascular Mechanics and Pathology
Vascular Mechanics and Pathology focuses on the artery and arterial diseases. As the fundamental functions of the artery are to serve as a conduit of blood flow and as a container of blood pressure, Vascular Mechanics and Pathology describes both the general principles and the occurrence of stress concentration at the pressure vessel junctions and examines the role of beta-blockers in the reduction of atherosclerosis and related complications. This cutting-edge work presents the use of veins as arterial grafts and discusses the role of vein valves in graft stenosis. Vascular Mechanics and Pathology illustrates aneurysm formation, growth, and rupture, using pressure vessel principles. This new work details the investigation of, amongst other topics, aortic dissection, showing for the first time that the aortic root mechanics plays a vital role in the development of this pathology.
Vascular Interventional Radiology : Angioplasty, Stenting, Thrombolysis and Thrombectomy
Focusses on the current evidence surrounding the use of endovascular therapy. It updates and complements the earlier Medical Radiology volume on the Radiology of Peripheral Vascular Diseases. Some background information is provided on vascular biology and the facilities required for safe endovascular practice, along with guidance on consent issues. Further chapters deal with endovascular treatment in particular arterial territories, and include the evidence in favour of or against the use of specific treatments. The most up-to-date evidence surrounding endovascular aneurysm repair is discussed. There are also chapters on venous interventions, including the endovascular management of varicose veins. This book will be of value both to interventional radiologists and to vascular surgeons with an interest in endovascular techniques.

Variational and Quasi-Variational Inequalities in Mechanics
The variational method is a powerful tool to investigate states and processes in technical devices, nature, living organisms, systems, and economics. The power of the variational method consists in the fact that many of its sta- ments are physical or natural laws themselves. The essence of the variational approach for the solution of problems rel- ing to the determination of the real state of systems or processes consists in the comparison of close states. The selection criteria for the actual statesmust be such that all the equations and conditions of the mathematical model are satis?ed. Historically, the first variational theory was the Lagrange theory created to investigate the equilibrium of finite-dimensional mechanical systems under holonomic bilateral constraints (bonds). The selection criterion proposed by Lagrange is the admissible displacement principle.
Variational and Potential Methods for a Class of Linear Hyperbolic Evolutionary Processes
