We consider the problem of designing (or augmenting) an electric power system such that it satisfies the N-k-ε survivability criterion while minimizing total cost. The survivability criterion requires that at least (1− ε) fraction of the total demand can still be met even if any k (or fewer) of the system components fail. We formulate this problem, taking into account both transmission and gene...

Many universities now teach courses in expert systems. In these courses students study the architecture of an expert system, knowledge acquisition techniques, methods of implementing expert systems and verification and validation techniques. A ma jot component of any such course is a class project consisting of the design and implementation of an expert system. This paper discusses a number of ...

Orphanin FQ/nociceptin (OFQ/N) was the first novel neuropeptide discovered as the natural ligand of an orphan G protein-coupled receptor (GPCR). Orphan GPCRs are proteins classified as receptors on the basis of their sequence similarities to known GPCRs but that lack the ligands that activate them in vivo. One such orphan GPCR exhibited sequence similarities with the opioid receptors. OFQ/N was...

This paper describes the third participation of IR-n system at CLEF-2003. Two previous participation are focused on Spanish monolingual task. This year, we participated in three different tasks: multilingual task (four languages), bilingual task (Italian-Spanish) and monolingual task (Spanish, German, French, Italian). This paper describes the experiments carried out as training process in orde...

Top-N recommender systems have been investigated widely both in industry and academia. However, the recommendation quality is far from satisfactory. In this paper, we propose a simple yet promising algorithm. We fill the user-item matrix based on a low-rank assumption and simultaneously keep the original information. To do that, a nonconvex rank relaxation rather than the nuclear norm is adopte...

background & objectives: in the 6-billion-population world 2000, approximately 10 million cancers were diagnosed, among which there were an estimated 6.2 million cancer deaths. whereas the universality of cancer incidence and mortality is established, the burden of cancer by type or organ site is distributed unequally between developing and industrialized nations. we want to collect some inform...

haemovigilance is a system with standard program to cover the entire transfusion chain, monitor, evaluate and analyse the data to improve patients’ safety. we report the implemented haemovigilance system in hospitals and transfusion reactions (tr) in iran. methods and materials: this was a prospective descriptive study. the national reporting system for transfusion incidents was introduced in j...
