An evaluation of public employment programmes in the East German state of Sachsen-Anhalt by M Eichler( Book )
10 editions published between 1998 and 1999 in English and held by 25 WorldCat member libraries worldwide
In East Germany, active labour market policies (ALMPs) are used on a large scale to contain fast rising unemployment after unification. This paper evaluates the effects for participants in public employment programmes (PEPs), that are an important part of ALMPs. It focuses on individual unemployment probabilities. By concentrating on the state of Sachsen-Anhalt, the econometric analysis can use a new and large panel, the Arbeitsmarktmonitor Sachsen-Anhalt. We aim at nonparametric identification of the effects of PEPs by combining the use of comparison groups with differencing over time to correct for selection effects. Our results indicate that PEP participation reduces the unemployment risk of the participants
Breitbandige Beamforming-Algorithmen zur Erfassung von Audiosignalen mit kompakten Mikrofon-Arrays by M Eichler( )
1 edition published in 2009 in German and held by 13 WorldCat member libraries worldwide
Mikrofon-Arrays erlauben die selektive Erfassung und Trennung von Audiosignalen aus einer akustischen Umgebung. Typische Anwendungen sind z.B. die Ortung einzelner Schallquellen, die räumliche Kartierung eines Schallfeldes ("akustische Kamera") oder der gerichtete Empfang einer bestimmten Schallquelle bei gleichzeitiger Unterdrückung von Umgebungs- oder Störschallen. Vielkanalige Verfahren und Filter, die sich dieser Aufgabe widmen, werden als Beamforming bzw. Beamformer bezeichnet. In dieser Dissertation werden bekannte und eigene Beamforming-Ansätze im Hinblick auf ihre Eignung für die hochwertige Übertragung von Audiosignalen untersucht. Diese erfordert neben einer möglichst großen Abdeckung des relevanten Frequenzbereichs (Breitbandigkeit) auch die Frequenzunabhängigkeit der Richtcharakteristik, um spektrale Verzerrungen zu vermeiden. Es wird ein Algorithmus vorgestellt, der diese Anforderungen mit sehr kompakten Arrays erfüllt. Eine klassische Möglichkeit, eine frequenzinvariante Charakteristik (Beampattern) mithilfe eines Delay-and-Sum-Beamformers zu erhalten, ist eine frequenzabhängige Gewichtung der Mikrofone, welche die effektive Apertur des Arrays proportional zur Schallwellenlänge einstellt. Diese Methode funktioniert jedoch nur bei Wellenlängen, die kleiner sind als die Ausdehnung des Arrays, und erfordert bei Frequenzen unter 100Hz Arrays von mehreren Metern Größe.
