Tone Mapping Operators (TMOs) compress High Dynamic Range (HDR) contents to address Low Dynamic Range (LDR) displays. While many solutions have been designed over the last decade, only few of them can cope with video sequences. Indeed, these TMOs tone map each frame of a video sequence separately, which results in temporal incoherency. Two main types of temporal incoherency are usually consider...

Many books on polarization give tables of Mueller matrices. The coherency matrix has been found useful for interpretetion the matrix. Here we a table matrices M, C, and factors F different components systems. is not given some complicated nondeterministic cases. In many cases, though, very simple form. particular, expressions general case an homogeneous elliptic diattenuating retarder. Differen...

This paper presents: (i) an operational semantics, based on a functional framework, for a concurrent and distributed extension of the Scheme programming language, (ii) a coherency protocol taking care of shared mutable objects, (iii) a new coherency protocol to imperatively control hierarchical groups of cooperating tasks. These two protocols do not require broadcast, nor FIFO communications, n...

In this article, the authors studied the developmental trajectories of three teachers as they integrated GroupScribbles (GS) technology in their classroom lessons over a semester period of about 5 months. Coherency diagrams were used to capture the complex interplay of a teacher’s knowledge (K), goals (G) and beliefs (B) in leveraging technology effectively in the classroom. The degree of coher...

Query translation in cross-language information retrieval (CLIR) can be done by employing dictionaries, aligned corpora, or machine translators. Scarcity of aligned corpora for various domains in many language pairs intensifies the importance of dictionary-based CLIR which motivates us to use only a bilingual dictionary and two independent collections in source and target languages for query tr...

We realize a fiber Bragg grating InGaN-based laser diode emitting at 400 nm and demonstrate its high coherency. Thanks to the fabrication of narrowband in near-UV, we can reach single-mode single-frequency regimes for self-injection locked diode. The device exhibits 44 dB side-mode suppression ratio mW output power. Detailed frequency noise analysis reveals sub-MHz integrated linewidth 16 kHz i...

Some parallel applications do not require a precise imitation of the behaviour of the physically shared memory programming model. Consequently, certain parallel machine architectures have elected to emphasise different required coherency properties because of possible efficiency gains. This has led to various definitions of models of store coherency. These definitions have not been amenable t o...

this paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. an interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...

Our research focuses on developing design-oriented analytical tools that enable us to better understand how a network comprising dynamic and static elements behaves when it is set in oscillatory motion, and how the interconnection topology relates to the spectral properties of the system. Such oscillatory networks are ubiquitous, extending from miniature electronic circuits to large-scale power...
