در این مقاله، تصحیح هندسی تصاویر آرایه خطی ماهواره ای با استفاده از دو روش مستقیم و غیر مستقیم انجام می شود. در روش مستقیم برای تعیین مختصات زمینی، پیکسل ها از پارامترهای مداری ماهواره و شرط هم خطی استفاده می شود. در روش غیر مستقیم، نقاط کنترل زمینی برای این منظور به کار گرفته می شود. پس از تعیین مختصات زمینی تعدادی از پیکسل ها، بقیه پیکسل های تصویر با استفاده از تبدیل چند جمله ای درجه دو بر رو...

 In this paper, we introduce a suitable generalization of Cayley graphs that is defined over polygroups (GCP-graph) and give some examples and properties. Then, we mention a generalization of NEPS that contains some known graph operations and apply to GCP-graphs. Finally, we prove that the product of GCP-graphs is again a GCP-graph.

Chemokines are important mediators of leukocyte migration during the inflammatory response. Post-translational modifications affect the biological potency of chemokines. In addition to previously identified NH2-terminally truncated forms, COOH-terminally truncated forms of the CXC chemokine murine granulocyte chemotactic protein-2 (GCP-2) were purified from conditioned medium of stimulated fibr...

Previous studies have demonstrated that the novel protein Gcp is essential for the viability of various bacterial species including Staphylococcus aureus; however, the reason why it is required for bacterial growth remains unclear. In order to explore the potential mechanisms of this essentiality, we performed RT-PCR analysis and revealed that the gcp gene (sa1854) was co-transcribed with sa185...

Our previous studies demonstrated that a putative Staphylococcus aureus glycoprotease (Gcp) is essential for bacterial survival, indicating that Gcp may be a novel target for developing antibacterial agents. However, the biological function of Gcp is unclear. In order to elucidate the reason that Gcp is required for growth, we examined the role of Gcp in bacterial autolysis, which is an importa...

Since 1991 the European Medicines Agency (EMA, formerly EMEA) adopted the Guidelines of the International Conference onHarmonization (ICH) onGoodClinical Practice (GCP). In this regard, one European Union (EU) Guideline and three EU Directives are in force at present, that is, the E6/CPMP/ICH/135/95 GCP Guideline, Directive 2001/83/EC (Community Codex on Pharmaceuticals), Directive 2001/20/ EC ...

Our previous studies revealed that the staphylococcal protein Gcp is essential for bacterial growth; however, the essential function of Gcp remains undefined. In this study, we demonstrated that Gcp plays an important role in the modulation of the branched-chain amino acids biosynthesis pathway. Specifically, we identified that the depletion of Gcp dramatically elevated the production of key en...

Generalized Constant Propagation (GCP) statically estimates the ranges of variables throughout a program. GCP is a top-down compositional compiler analysis in the style of abstract intepretation. In this paper we present an implementation of both intraprocedural and interprocedural GCP within the context of the C language. We compare the accuracy and utility of GCP information for several versi...

The O-sialoglycoprotein endopeptidase (glycoprotease, Gcp) is secreted by Pasteurella haemolytica A1, a Gram-negative pathogen associated with bovine pneumonic pasteurellosis. When the cloned gcp gene is expressed in Escherichia coli, the recombinant glycoprotease (rGcp) is exported to the periplasm but does not exhibit enzymatic activity. Polyclonal calf sera and murine monoclonal antibodies t...

modeling of network security is useful approach to comprehend the status. In this paper, network is modeled in a graph. Security problem is solved in graph as Graph Coloring Problem (GCP). In GCP, two adjacent nodes must have different colors. Thus GCP provides the security in the network. One objective in GCP is chromatic number and another objective is total price. We present a multi-objectiv...
