protection systems have vital role in network reliability in short circuit mode and proper operating for relays. current transformer often in transient and saturation under short circuit mode causes mal-operation of relays which will have undesirable effects. therefore, proper and quick identification of current transformer saturation is so important. in this paper, an artificial neural network...

This paper presents an experimental investigation of the Sounds of Silence (SoS) harmony search metaheuristic for the multi-mode resource-constrained project scheduling problem (MRCPSP) using a pre-optimized starting repertoire. The presented algorithm is based on the time oriented version of the SoS harmony search metaheuristic developed by Csébfalvi et al. [1] for the single-mode resource-con...

A new H.264 fast inter-mode decision algorithm based on coded block patterns is presented. Compared to the exhaustive mode search, the proposed method achieves an average 57% reduction in computation time with negligible degradation in visual quality. The speed and rate-distortion performance is comparable to known fast algorithms that involve more elaborate mechanisms.

We report on results of a search for the decay mode KL → π γee conducted by the E162 experiment at KEK. We observed no events and set a 90% confidence level upper limit of Br(KL → π γee) < 7.1× 10 for its branching ratio. This is the first published experimental result on this decay mode. PACS: 13.20.Eb, 14.40.Aq

Scalable video coding (SVC) is an extension of H.264/AVC for providing three types of scalabilities: temporal, spatial, and quality. These scalabilities can be combined to make use of network bandwidth. As an extension of the H.264/AVC video standard, an inter-mode prediction technique is used for reducing temporal as well as spatial redundancies by using seven variable-sized macroblocks (MBs) ...

A miniature on-chip laser is an essential component of photonic integrated circuits for a plethora applications, including optical communication and quantum information processing. However, the contradicting requirements small footprint, robustness, single-mode operation, high output power have led to multi-decade search optimal design. During this search, topological phases matter—conceived in...

A new family of very fast stream ciphers called COS (for “crossing over system”) has been proposed by Filiol and Fontaine, and seems to have been adopted for at least one commercial standard. COS(2,128) Mode I and COS(2,128) Mode II are particular members of this family for which the authors proposed a cryptanalysis challenge. The ciphers accept secret keys of 256, 192 or 128 bits. In this note...

We study the constraints on the anomalous coupling gZ 5 that can be obtained from the analysis of the reaction γγ → WWZ at future linear ee colliders. We find out that a 0.5 (1) TeV ee collider operating in the γγ mode can probe values of gZ 5 of the order of 0.15 (4.5×10−2) for an integrated luminosity of 10 fb. This shows that the ability to search for this anomalous interaction of the γγ mod...

This paper describes new simulated annealing (SA) algorithms for the resource-constrained project scheduling problem (RCPSP) and its multiple mode version (MRCPSP). The objective function considered is minimisation of the makespan. The conventional SA search scheme is replaced by a new design that takes into account the specificity of the solution space of project scheduling problems. For RCPSP...

The Search-Browse-Repeat (SBR) mode of Web usage is becoming increasingly important as the size of the Web increases and the coverage of search engines expands. However, Web browsers do little to support SBR, with consequences for search success rates. We characterise the main features of SBR, suggest criteria that would help alleviate the problems associated with it, and outline a prototype br...
