Taschenbuch. Zustand: Neu. Neuware -Based on the analysis of successive space-time transformation with direction changed, we prove the Galilean transformation can be derived by two postulates, the principle of relativity, and the homogeneous and isotropic of time and space that meets the Euclidean geometry. As the two postulates are also believed to be satisfied by the special relativity, we further demonstrate the successive Lorentz boost with direction changed will lead to paradox. It is discussed the Wigner rotation should not be regarded as the relativistic effect for the composition of two Lorentz boosts, but it will give contradictory events against the Euclidean geometry. We believe seeking new space-time model for the special relativity would be the most feasible approach, and a hypothesis of 3+3 space-time model is proposed to solve the paradox. We also extend the Maxwell equations to the 3+3 space-time and obtain the new electromagnetic field quantities and the corresponding covariant electromagnetic field equations. It is discussed the 3+3 space-time can be approximated to the 3+1 space-time and the new field equations based on the 3+3 space-time can also be approximated to the Maxwell equations.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This thesis work addresses the bilateral teleoperation of a planetary rover, named MERLIN (Mobile Experimental Robot for Localization and Intelligent Navigation). The teleoperation platform is built up between the rover and a haptic device. The haptic device provides a force-feedback mechanism, which describes the environmental conditions regarding the obstacles, based on the ranging information from the rover. Therefore, obstacle avoidance can be achieved independent of the visualization of the environment, which, on the other hand, will reduce the communication burden. This can be highly desirable in low-light conditions and in remote teleoperation cases, in which difficulties may arise in visualizing the surroundings. Communication delay is the main concern in this thesis work, because it will result in poor performance of the overall system and even lead to instability of the closed-loop teleoperation. The technology developed in this thesis work will improve the quality of navigating MERLIN rovers. and provide basics for teleoperation of multiple mobile robots, as well as robotic maneuvers by means of mobile manipulators.Books on Demand GmbH, Überseering 33, 22297 Hamburg 96 pp. Englisch.

Zustand: Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | This book focuses on the development of DGT (diffusive gradients in thin films) and the related techniques for measuring and investigating the geochemical process and P transfer across the sediment/water or sediment/root interface in lakes. A series of DGT techniques such as new types of probes, test methods in sediment or the rhizosphere, DIFS (DGT induced fluxes in sediments and soils) model for kinetic P exchange, CID (computer imaging densitometry) for S(-II), and microchelex gel/LA-ICP-MS (laser ablation inductively coupled plasma mass spectrometry) have been developed. The corresponding chapters on the theory and methodology of DGT, the ¿internal P loading¿ or P transfer across sediment/root in two lakes, provide insights into the research method and conclusions, including the P release mechanism, the quantification of ¿internal P loading¿, kinetic P exchange in DGT/sediment interface, Fe- or S(-II)-microniches at submillimeter scales in sediments for the prediction ofP release, and DGT as a surrogate for the prediction of P uptake by roots. It also offers new perspectives in the fields of P analysis and P process in micro-interfaces in lakes using DGT techniques. The P remobilization from Fe-bound P, the coupled Fe-S(-II)-P geochemical reaction and algae biomass breakdown causing P release, are elucidated using DGT methods in sediment layers. DGT parameters and curves for time or distance derived from DIFS can be used to assess kinetic P release in the sediment microzone. CID and LA-ICP-MS methods deliver Fe- and S(-II) images at submillimeter scales, which can be used for the quantification of flux related to microniche peaks and the prediction of P release from Fe-microniche or Fe-S(-II)-P geochemical reactions. DGT measurements in-situ in rhizosphere or rhizonbox can give CE (effective concentration) and CDGT values for the prediction of P accumulated in plant tissues. This book provides a valuable reference resource for senior graduate students, lecturers and researchers in the fields of the geochemical process of eutrophic elements in lakes, lake eutrophication mechanism and environmental analysis.

'Southern Hokkien: An Introduction is a research-based textbook originally designed for non-heritage learners who acquired a reasonably good proficiency level of Mandarin and wish to learn the Southern Hokkien language outside its natural linguistic environment. It uses a situation-based approach in which dialogues are designed to reflect scenes in real life rather than classroom situation. Grammar and vocabulary explanations follow a primarily contrastive approach, focussing on similarities and differences between Mandarin and Southern Hokkien. Though mainly based on dialect variants spoken in Taiwan, Southern Hokkien also includes references to dialect variants spoken in other Hokkien speaking areas. The textbook is complemented by a number of excursions and explanatory comments which help not only to follow required linguistic rules and cultural conventions but also to gain a basic understanding of the reasons behind some of these rules and conventions.'.

Taschenbuch. Zustand: Neu. Neuware -Diese Untersuchung befasst sich aus rechtsvergleichender Sicht und insbesondere im Hinblick auf die Herausforderungen der Digitalisierung mit dem Urheberrecht und seinen Schranken und zieht daraus Schlussfolgerungen für eine mögliche zukünftige Regelung im chinesischen Urheberrecht. Bei den Schranken stehen sich die Modelle des angloamerikanischen Fair Use und der kontinentaleuropäischen enumerativen Schranken gegenüber. Im Urheberrecht seht China immer noch zwischen den beiden großen Urheberrechtssystemen. Der dreiseitige Rechtsvergleich ist deswegen sinnvoll und notwendig. Im Mittelpunkt der Arbeit seht die Fortentwicklung des chinesischen Urheberrechts. Dennoch kann die Untersuchung auch die Diskussion in Europa erneut anregen, denn auch hier ist die betreffende Problematik offengeblieben.Books on Demand GmbH, Überseering 33, 22297 Hamburg 198 pp. Deutsch.
