Die Zukunft unserer Energieversorgung Eine Analyse aus mathematisch-naturwissenschaftlicher Sicht

Das Buch behandelt die Energie als Mittel zur Entropieerzeugung, welche die Voraussetzung für alle auf der Erde ablaufenden Prozesse ist. Die verfügbaren Energieträger werden unterschieden in erneuerbar und nichterneuerbar. Für letztere wird ihre Reichweite mithilfe mathematischer Modelle berechnet, wobei die Entwicklung der Bevölkerungszahlen und des Lebensstandards berücksichtigt werden.

Camera Networks: The Acquisition and Analysis of Videos overWide Areas

As networks of video cameras are put in in lots of purposes like safety and surveillance, environmental tracking, catastrophe reaction, and assisted residing amenities, between others, photo knowing in digicam networks is changing into an immense zone of analysis and expertise improvement. there are lots of demanding situations that must be addressed within the technique.

Asymptotic Analysis for Functional Stochastic Differential Equations

This short treats dynamical platforms that contain delays and random disturbances. The research is encouraged through a wide selection of structures in actual existence during which random noise needs to be considered and the impression of delays can't be overlooked. targeting such structures which are defined by means of useful stochastic differential equations, this paintings makes a speciality of the research of enormous time habit, particularly, ergodicity.

Issues which must be considered beyond the algorithm's ability to estimate parameters include: how the determination of fault type is connected to the parameter estimation, monitoring of the quality of the estimates, and speed-reach considerations. In this section we will concentrate on issues related to the algorithms. It should be recognized, however, that a complete relaying program could also include: phase and ground distance protection, some directional comparison scheme, three-zone stepped distance protection, provision for single phase-tripping, high speed reclosing, auto-reclosing with sync check, breaker failure protection, sequence of events recording, and memory voltage for three-phase bus fault.

87) are not correctly scaled. The factor of 1/3 from Eq. (79) and the 2/K from Eqs. (23) and (24) along with the fi, from Eq. (35) should be considered if the actual phasors are needed. C. TRANSIENT MONITOR The difficulty with the unreliability of the estimates when the data window spans the pre-fault post-fault interval can be overcome by disabling the relay when the estimate does not fit the data. If we compute the samples that would result from the estimate denoted by the vector x then x = S X = S (STS ) _ 1 S T x (88) The samples and the reconstructed samples x are shown in Figure 14.

If we let v(t) and i(t) satisfy the differential equation, and denote the measured current and voltage by im(t) and vra(t) respectively, then 30 JAMES S. THORP AND ARUN G. (t) + L ^ ί ί ) = v (t) + R Ci(t) + L â l i Û ) dt dt and the current im(t) and voltage vm(t) are related by: R im(t) + L ^aii) = vm(t) + R €i(t) + L 4ÜÜ1 - ev(t) dt dt (46) (47) In other words, the measured voltage and current satisfy a differential equation such as Eq. (37) where the "currents" are without error and the "voltage" has an equivalent error made up of the voltage error plus a processed current error term.
