background: postoperative cognitive dysfunction (pocd) has been an important complication of cardiac surgery over the years. neurocognitive dysfunction can affect quality of life and lead to social, functional, emotional, and financial problems in the patient’s life. to reduce pocd, we sought to identify the association between cognitive dysfunction and perioperative factors in patients undergo...
7 In feature based object recognition an essential step is finding the locations of the 8 local object features in the image by maximizing a feature similarity function. We 9 study the mapping of a feature similarity function to a likelihood function that 10 reflects the actual probabilities related to associating the object point in a certain 11 location in the image. We adopt probabilistic ap...
in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
بررسی ارزش غذایی تاغ و عمل آوری آن با سود و آهک در مراحل مختلف رشدبا استفاده از روش کیسه های نایلونی
abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
An overview of the research and associated activities of the European collaborative ESPRIT Basic Research ProCoS II project (no. 7071) on \Provably Correct Systems" which ran from 1992 to 1995 is presented. This was a follow-on project to ProCoS (no. 3104) and ran in parallel with the ProCoS-WG Working Group (no. 8694), all previously announced in the Bulletin of the EATCS [3, 17, 18]. A compre...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
INTRODUCTION The developmental changes that occur as a result of puberty have been hypothesized to be important causes of varicocele. Various somatometric parameters were known to affect the occurrence of varicocele during the growth period. We conducted this study in order to examine these relationships and to determine the incidence of varicocele in adolescent males. PATIENTS AND METHODS We...
The parameters of metric, cometric, symmetric association schemes with q 6= ±1 (the same as the parameters of the underlying orthogonal polynomials) can be given in general by evaluating a single rational function of degree (4, 4) in the complex variable q j . But in all known examples, save the simple n-gons, these reduce to polynomials of degree at most 2 in q j with q an integer. One reason ...
there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
the ion-pair association constant values, related to the reaction + were determined by means of the nmr spectroscopy. the values of the thermodynamic functions of the ion pairing process were calculated on the basis of the nmr results. in addition, the association entropy was found to be dependent on the temperature. comparing the experimental data and the fuoss theory it is found that ion-pa...
