Numerical Analysis of the Heat Transfer in Hetero junction Device for Optoelectronic Applications

Physical and numerical descriptions related to the heat transfer phenomenon inside the multilayer nanomaterial of thin film are determined. The mathematical model, of a multilayer of thin film of tin dioxide that deposits on a composite substrate of Silicon Dioxide/Silicon, is studied and solved by two numerical techniques, by taking into account the variability of the thermal conductivity. 

The two main interests in this study are the determination of the value of the applied maximum temperature on the multilayer nanomaterial, and the analysis, of theeffect of the porosity medium that exists between certain layers, on the heattransfer. In plus, in order to determine our system physical parameters, the influence of the thickness of the thin deposit film is studied and the numerical model, which estimates these values in the hetero junction device, is analysed.

With the continued reduction of dimensions of technological devices, the heat produced can be important, component failures can occur. According to NASA, 90% of failures are due to defects and thermal interconnects, according to the USAir Force, 55% of electronic failures are due to thermal effects. 

Comparison between Robust and Classical Analysis in Bivariate Logistic for Medical Data

Representing medical data and biological important part in experiments are concerned with Human life, the primary objective of this research is to use the statisticaloptimization method analysis for the data and knowledge of the important factors affecting the variables of the study (liver fat, liver size), where the variables are interconnected there is a need for statistical method to examines the degree of their relationship, we used bivariate logistic. 

To achieve the of the research on the field study will be done in Al-Sadr medical city in the province of Najaf by taking a sample of 150 people auditors diabetes and liver disease center, from the statistical analysis results we observed the degree of diagnosis model in both method are good, and also we monitored that impactfactors in responses (liver fat, liver size) and some comment as multivariatelogistic in the Future.

This research(study) aims to review the method of bivariate logistic distribution in order to study and analysis effecting factors on the response variables (the degree of liver fatty and increase of liver size in Human beings) using the data of medical tests to compare classical and robust analysis when some values are outlier in the sample.

Time Scan Statistics for High-risk Clusters of Tuberculosis (TB) Disease

Tuberculosis (TB) is a disease caused by bacteria that are spread through the air from person to person. If not treated properly, TB disease can be fatal. People infected with TB bacteria who are not sick may still need treatment to prevent TB disease from developing in the future. 

Tuberculosis (TB) is currently one of the greatest problems in public health. Mycobacterium tuberculosis infects about one third of the world's population, of whom more than 80% are living in developing countries. The incidence andprevalence of TB are very different in various parts of Iran and alsothroughout the world. Learn to recognize the symptoms of TB disease and find out if you are at risk.

Algebra, Hyperalgebra and Lie-Santilli Theory

The theory of hyperstructures can offer to the Lie-Santilli Theory a variety of models to specify the mathematical representation of the related theory. In this paper we focus on the appropriate general hyperstructures, especially on hyperstructures with hyperunits. We define a Lie hyperalgebra over a hyperfieldas well as a Jordan hyperalgebra, and we obtain some results in this respect. Finally, by using the concept of fundamental relations we connect hyper algebras to Lie algebras and Lie-Santilli-addmissible algebras.

The structure of the laws in physics is largely based on symmetries. The objects in Lie theory are fundamental, interesting and innovating in both mathematics and physics. It has many applications to thespectroscopy of molecules, atoms, nuclei and hadrons. The central role of Lie algebra in particle physics is well known. A Lie-admissible algebra, introduced by Albert, is a (possibly non-associative) algebra that becomes a Lie algebra under the bracket [a,b] = ab − ba. Examples include associative algebras, Lie algebras and Okubo algebras. Lie admissible algebras arise in various topics, including geometry of invariant affine connections on Lie groups and classical and quantum mechanics.

On Duality of Multiobjective Rough Convex Programming Problems

Duality assertions are very important in optimization from the theoretical as well as from the numerical point of view. So this paperpresents duality of multiobjective rough convex programming problems in roughenvironment when the multiobjective function is deterministic and roughness is in feasible region. 

Also it discussed the duality when roughness in multiobjective function and the feasible region is deterministic. The conceptsand some theorems of duality in the rough environment are discussed. Also, the procedure of solution of these kind of problems described.

The mathematical programming in rough environment was introduced. The multiobjective rough convex programming problem (MRCPP) can be classified according to existence of roughness is in multiobjective function or constraints. The mathematical problems can be classified into three classes. First class: MRCPP with rough feasible set and deterministic multiobjective function. Second class: problems with deterministic feasible set and rough multiobjective function.

Comparison of Macrodosimetric Efficacy of Transarterial Radioembolization (TARE)

Purpose: Transarterial 90Y microspheres radioembolization is emerging as a multidisciplinary promising therapeutic modality for primary and metastatic cancer in the liver. Actually two different type of microspheres are used, whose main characteristic is the different density of activity (activity per microsphere). In this paper the effect due to the possible different distribution of the microspheres in a target is presented and discussed from a macrodosimetric point of view.

Material and methods: A 100 g virtual soft-tissue target region has been builded. The administered activity was chosen to have a target average absorbed dose of 100 Gy and the number of 90Y microspheres needed was calculated for two different activity-per-microsphere values (2500) Bq/microsphere and 50 Bq/microsphere, respectively). The spheres were randomly distributed in the target and the Dose Volume Histograms were obtained for both. The cells surviving fractions (SF) for four different values of the radiobiological parameter α were calculated from the Linear - Quadratic model. 

Results: The DVH obtained are very similar and the SF is almost equal for both the activity-per- microsphere values. Conclusions: This macrodosimetric approach shows no radiobiological difference between the glass and resin microspheres. Thus the different number of microspheres seems to have no effect when the number of spheres is big enough that the distance between the spheres in the target can be considered small compared to the range of the β-particles of 90Y.Read More...
