A "brain defibrillator" may be closer than we think. An epileptic seizure involves a paroxysmal change in the activity of millions of neurons. Feedback control of seizures would require an implantable device that could predict seizure occurrence and then deliver a stimulus to abort it. To examine the feasibility of building such a device, this text brings together experts in epilepsy, bio-engineering, and dynamical systems theory. Topics include the development of epileptic systems, seizure prediction, neural synchronization, wave phenomena in excitable media, and the control of complex neural dynamics using brief electrical stimuli.

The GSM system is undoubtedly the most successful second-generation digital mobile radio system. One of the key factors for this exceptional performance is the constant evolution of the GSM system and its derivatives. GSM: Evolution towards 3rd generation systems addresses new concepts in the GSM system, dealing both with standardized features as well as with theoretically and technologically feasible improvements which contribute to evolutionary changes in general. Ongoing efforts in GSM standardization are focused on Phase 2+ with gradual additions for a fast and modular evolution. Speech remains the prime service of cellular systems, with ongoing work on spectral efficiency taking into account the tradeoff between cost of the system and transmission quality. Most of the notable results from novel speech service implementations are addressed herein such as new EFR speech codec and Advanced Speech Cell Items (ASCI). Data capability in Phase 2+ has been covered under General Packet Radio Service (GPRS) and High-Speed Circuit Switched Data (HCSD) work items. Initiatives under CAMEL cover intelligent networking (IN) within the GSM framework. Dual mode operation in GSM includes not only dual-band solutions but also inter-networking with other systems like DECT or satellite systems. Numerous specific wireless applications such as inbuilding communications, WLL, etc., have also been developed based on GSM. To support the required changes a number of issues have to be solved in the radio part of the system. Deployment of adaptive antenna arrays for enhanced quality, interference suppression techniques and slow frequency hopping are among the techniques presented in the GSM framework. Dynamicevolution of GSM presents a platform for the introduction of UMTS. Presently, efforts are directed towards the standardization of the UMTS air interface in ETSI. Major trends in progress towards new radio interfaces are outlined including contributions from pan-European projects such as ATDMA, which was carried out under the RACE II framework, and the ACTS project AC090 FRAMES. GSM: Evolution towards 3rd generation systems comprises a collection of specially written contributions from GSM specialists. The information presented is essential reading for all researchers, engineers and managers working on GSM and third generation wireless systems. This book covers the most important advances in GSM that will have lasting impact on the system influencing third generation wireless systems.

1m dualen Ausbildungssystem arbeiten Berufsschule und Ausbildungsbetrieb zusammen, urn das Ausbildungsziel "Verkaufer im Einzelhandel" zu erreichen. Der Berufsschule kommt die Ausbildung mit dem Schwerpunkt "Theorie", dem Ausbildungsbetrieb die Ausbildung mit dem Schwerpunkt "Praxis" zu. Beide arbeiten zwar zusammen, doch ist nicht auszuschlieBen, daB in manchen Bereichen Oberschneidungen, in anderen LUcken vorkommen. Das vorliegende Buch ist so konzipiert, daB beide Ausbildungsinhalte berUcksichtigt werden. Dem Ausbildungsbetrieb und den Ausbildem wird ein Kompendium zur Hand gegeben, das beide Gesichtspunkte berucksichtigt. Am Ende der Ausbildungszeit steht die Prufung "Verkaufer im Einzelhandel", die beide Bildungsinhalte umfaBt. Dem Ausbilder wird mit diesem Buch eine Hilfe gegeben, die ihm eine Handreichung bietet, betriebliche und schulische Ausbildung zu koordinieren. Das vorliegende Fragenkompendium hat also zwei Aufgaben: Hilfe flir den Ausbilder und Leitfaden fUr den Auszubildenden zu sein. Seit geraumer Zeit arbeiten verschiedene Industrie- und Handelskammem auch beim Ausbildungsberuf Verkaufer mit Ausbildungsplanen in Checklistenform. Diese Check- listen sind nach betrieblichen Funktionsbereichen gegliedert und enthalten eine vollstan- dige Aufzahlung der Ausbildungsinhalte, zu deren Vermittlung der Ausbildungsbetrieb verpflichtet ist. Allerdings mit der Einschrankung, daB prufungsrelevante Gebiete nicht oder nur unzureichend berucksichtigt werden. Dieser Mangel wird im vorliegenden Buch mit dem Anhang zur Checkliste ausgeglichen.
