Random lasers are exotic light sources that emit coherent light without any of the confining mirrors that are part of a conventional laser.1, 2 Instead, the light inside a random laser is trapped by multiple scattering in a disordered medium and can thus be efficiently amplified. The downside is that random lasers emit their light at many different frequencies and in many different directions (...

This article presents the strategic learning meta-model (SLM). We describe the architecture of the SLM, which consists of three layers: reactive layer, intelligent layer and infrastructure layer. The purpose of this paper is to present the reactive layer of the SLM and in particular the model that constitutes: the regulation model. This model was tested with a series of cases which indicate an ...

There are a number of manufacturing methods used for the manufacture of control valve trim components, some of which are expensive processes. Current market conditions and increased competition requires manufacturers to reduce costs of these components and they are investigating new technologies such as processes using Additive Layer Manufacturing (ALM) to produce these components. These proces...

Wenn das Potential der Flexibilität von SOA auf Basis der Änderbarkeit von Services erhalten und genutzt werden soll, ergeben sich besondere Herausforderungen beim Betrieb von SOA-basierten Lösungen. Dies wird am Beispiel des Service Level Management (SLM) und dem zur Überwachung und Auswertung erforderlichen Monitoring von Antwortzeiten demonstriert. Es wird gezeigt, dass dies eine Erweiterung...

The aberration introduced by the primary optical element of a lightweight large aperture telescope can be corrected with a diffractive optical element called the liquid crystal spatial light modulator. Such aberration is usually very large, which makes the design and modeling of such a system difficult. A method to analyze the system is introduced, and the performance limitation of the system i...

Motivated by the hypothesis that the retrieval performance of a weighting model is independent of the language in which queries and collection are expressed, we compared the retrieval performance of three weighting models, i.e., Okapi, statistical language modeling (SLM), and deviation from randomness (DFR), on three monolingual test collections, i.e., French, Italian, and Spanish. The DFR mode...

LLE Review, Volume 96 225 Laser-beam shaping is a rapidly developing field of research driven by both technological improvements of beam-shaping devices and the ever-increasing demands of applications. In high-energy laser chains, efficient beam shaping is successfully achieved in the front ends by passive methods such as beam apodization1 or intracavity mode shaping;2 however, these static tec...

We investigate the usage of class-based statistical language models (SLMs) for robust speech understanding. Generic classbased SLMs are built using data from several applications and then tested on data from a distinct target application to benchmark their portability. The results show that these generic classbased SLMs perform as well as those trained on data from the target testing applicatio...

Partial discharge monitoring provides effective evaluation of power cables, particularly of joints that are installed on site. Continuous on-line monitoring can provide information about progressing degradation under operational stresses, thus reducing the likelihood of breakdown. A novel PD continuous online monitoring technique has been developed by the authors. The mechanism applies PD signa...
