It is known that many image enhancement methods have a tradeoff between noise suppression and edge enhancement. In this paper, we propose a new technique for image enhancement filtering and explain it in human visual perception theory. It combines kernel regression and local homogeneity and evaluates the restoration performance of smoothing method. First, image is filtered in kernel regression....

There is a general process towards an understanding of knowledge not as a question of remembering facts but to achieve the skill to use what is learnt under different circumstances. According to this, knowledge should be useful at different occasions also outside school. This process may also be identified in the development of new tests performed in order to assess knowledge. In courses in bio...

We review some of the recent developments of optical performance monitoring (OPM) in various aspects: (i) the enhancement of monitoring resolution, (ii) multi-impairment monitoring, and (iii) OPM network optimization. In particular, some of the studies on the optimization of performance monitoring networks to achieve the optimal monitoring locations and the number of monitoring probes are discu...

This paper presents the participation of the CACAO prototype to the TEL@CLEF 2009 task, an evaluation track focusing on multilingual document retrieval over a collection of library catalogues. CACAO (Cross-language Access to Catalogues And On-line libraries) is an EU project devoted to enabling cross-language access to the contents of a federation of digital libraries with a set of software too...

Narcissists consider themselves to be exceptional performers, but past research has found no consistent relationship between narcissism and performance. The present research tested the hypothesis that the relationship between subclinical narcissism and performance is moderated by a motivational factor: perceived self-enhancement opportunity. Four experiments were conducted, each using different...

Purpose: to prove a technique of the improvement of special physical fitness due to the development of coordination abilities at a stage of the previous basic preparation. Material and Methods: theoretical analysis and synthesis of data of scientifically methodical literature and empirical materials of the scientific research, pedagogical methods of the research, tool methods: program of diagno...

Determination of pedal forces is a prerequisite to analyse cycling performance capability from a biomechanical point of view. Comparing existing pedal force measurement systems, there are methodological or practical limitations regarding the requirements of scientific sports performance research and enhancement. Therefore, the aim of this study was to develop and to validate a new bicycle instr...

A literature search and narrative review was carried out with the intent of determining the current level of knowledge regarding the chiropractic treatment of athletes for the purpose of sport performance enhancement. Of the fifty-nine relevant articles retrieved, only 7 articles of variable quality were obtained which specifically investigated/discussed chiropractic treatment and its involveme...

Terpyridine and quaterpyridine-based complexes allow wide light harvesting of the solar spectrum. Terpyridines, with respect to bipyridines, allow for achieving metal-complexes with lower band gaps in the metal-to-ligand transition (MLCT), thus providing a better absorption at lower energy wavelengths resulting in an enhancement of the solar light-harvesting ability. Despite the wider absorptio...
