This paper is concerned with the determination of optimal sensor locations for structural modal identification in a strap-braced cold formed steel frame based on an improved genetic algorithm (IGA). Six different optimal sensor placement performance indices have been taken as the fitness functions two based on modal assurance criterion (MAC), two based on maximization of the determinant of a Fi...

in order to evaluate the physiological indices in relation to the screening of spring safflower genotypes for drought tolerance and productivity, seed and oil yields and yield components were measured for five genotypes including local arak, local esfahan, sina, kh23 – 57 and goldasht. the study was conducted in a loam soil in east azarbaijan, iran, during three successive years (2005-2007)...

background: reference percentile curves are usually used as a screening tool to determine growth disorders. anthropometric indices are population-dependent and may differ according to ethnicity, dietary pattern and lifestyle habits. this study aims to compare the curves of anthropometric measures obtained in two national studies conducted among iranian children and adolescents in 2003-2004 and ...

concomitant research and education are invaluable for patient care and medical practice in trauma. elucidation of a foundation for the integration of training and service that can be combined with research in trauma is crucial, and every trauma case should be studied for this purpose. in this study, we investigated the unique features of trauma research to formulate a generic comprehensive mode...

let g be a graph. the first zagreb m1(g) of graph g is defined as: m1(g) = uv(g) deg(u)2. in this paper, we prove that each even number except 4 and 8 is a first zagreb index of a caterpillar. also, we show that the fist zagreb index cannot be an odd number. moreover, we obtain the fist zagreb index of some graph operations.

two dimensional slope profile morphometric investigation in a part of the land failure prone garhwal region of the lesser himalaya, tehri district, u. p., india, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. each ind...

introduction: human resource plays a very important role in the success or failure of a company. the weakness in conclusion of criteria of model efqm (employee's criteria and results) using fahp method (fuzzy analytical hierarchy process) will be discussed here as iranian organizations are usually weak in their results field. method: the present study is an applied research. procedure of doing ...

The prevalence of surgical trauma as a global public health hazard has been severely neglected. Trauma surgeons in Uganda and Canada have developed the Kampala Trauma Score (KTS), a trauma severity index specific to east African contexts. Hospitals in Tanzania have begun to use this tool to measure their own trauma management protocols in order to measure the validity of this index regionally. ...

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with diverse manifestations. Although the approval of new therapies includes only one agent in 50 years, a number of promising new drugs are in development. Lupus nephritis is a dreaded complication of SLE as it is associated with significant morbidity and mortality. Advancing the treatment of lupus nephritis requires well-desi...
