Taschenbuch. Condition: Neu. Neu Neuware; original eingeschweisst; Rechnung mit MwSt.; new item, still sealed; -Energy supply and use, together with the need of developing clean and renewable sources of energy, have become one of the defining challenges of the twenty-first century. Solar energy conversion is known to be a realistic alternative for a secure low cost energy supply and low carbon emissions. Regarded as the low cost next-generation of photovoltaics, the biomimetic dye sensitised solar cell uses a unique photoelectrochemical mechanism and resembles the photosynthesis in the plant leaves. In comparison to other photovoltaics technologies, the dye sensitised solar cell has exceptional features that are reviewed here. The book aims to contribute to the development of renewable energy and to the physics of solar cells, in particular to the dye sensitised solar cell. It also highlights, from a theoretical, experimental and economical point of view, some of the main aspects and issues that need to be addressed in dye sensitised solar cell research, aiming towards future improvements. 116 pp. Englisch.…

Hardcover. Condition: Very Good. Picture Boards. 1st Edition. Bottom tips of the boards have been bumped. Remnants of a past retailer's label on the rear board. In this book the authors present an alternative set theory dealing with a more relaxed notion of infiniteness, called finitely supported mathematics (FSM). It has strong connections to the Fraenkel-Mostowski (FM) permutative model of Zermelo-Fraenkel (ZF) set theory with atoms and to the theory of (generalized) nominal sets. More exactly, FSM is ZF mathematics rephrased in terms of finitely supported structures, where the set of atoms is infinite (not necessarily countable as for nominal sets). In FSM, 'sets' are replaced either by `invariant sets' (sets endowed with some group actions satisfying a finite support requirement) or by `finitely supported sets' (finitely supported elements in the powerset of an invariant set). It is a theory of `invariant algebraic structures' in which infinite algebraic structures are characterized by using their finite supports. After explaining the motivation for using invariant sets in the experimental sciences as well as the connections with the nominal approach, admissible sets and Gandy machines (Chapter 1), the authors present in Chapter 2 the basics of invariant sets and show that the principles of constructing FSM have historical roots both in the definition of Tarski `logical notions' and in the Erlangen Program of Klein for the classification of various geometries according to invariants under suitable groups of transformations. Furthermore, the consistency of various choice principles is analyzed in FSM. Chapter 3 examines whether it is possible to obtain valid results by replacing the notion of infinite sets with the notion of invariant sets in the classical ZF results. The authors present techniques for reformulating ZF properties of algebraic structures in FSM. In Chapter 4 they generalize FM set theory by providing a new set of axioms inspired by the theory of amorphous sets, and so defining the extended Fraenkel-Mostowski (EFM) set theory. In Chapter 5 they define FSM semantics for certain process calculi (e.g., fusion calculus), and emphasize the links to the nominal techniques used in computer science. They demonstrate a complete equivalence between the new FSM semantics (defined by using binding operators instead of side conditions for presenting the transition rules) and the known semantics of these process calculi.

Taschenbuch. Condition: Neu. Neuware -In the framework of a fast-changing globalized economy, European small and medium-sized enterprises (SMEs) are at the crossroads of international external pressures and internal reaction constraints. This volume draws upon the importance of leveraging European SMEs' intellectual capital in the context of internationalization and development of sustainable international partnerships, in order to create and maintain relevant competitive advantages. At a practical level, it explores the European initiatives and the Romanian legal, governmental and institutional instruments aimed at supporting the SMEs in their various endeavors, from accessing relevant knowledge to deploying successful operations in foreign markets. Thus, it offers insight and valuable knowledge to academics and managers interested in the international expansion of SMEs.This volume was supported by a grant of the Ministry of Research and Innovation, CNCS - UEFISCDI, project number PN-III-P1-1.1-TE-2016-0232, within PNCDI III. 164 pp. Englisch.…
