In the present paper, an analysis was carried out to investigate effects of radiation on a free convection flow bounded by a vertical surface embedded in a porous medium with constant suction velocity. It was under the influence of uniform magnetic field in the presence of a homogenous chemical reaction and viscous dissipation with constant heat and mass flux. The non-dimensional governing equa...

SUMMARY This paper speaks about a 63 year old woman with chronic non-specific pain in superior abdominal region and progressive cachexia. Clinical and paraclinical investigations revealed a large non­homogen mass of right liver lobe. After surgical approach 90% of right liver lobe was involved by a solid mass with necrotic areas. Microscopic evaluation disclosed a chronic granulomatous inflamm...

BACKGROUND Differentiating between benign and malignant submucosal tumors is difficult. Moreover, the natural course of benign-appearing SMTs is not clearly elucidated. OBJECTIVES To evaluate the natural course of upper gastrointestinal SMTs by endoscopic endosonography. METHODS We followed 25 consecutive patients with small (< 40 mm) SMTs for a mean period of 19 months. Evaluation included...

We derive and characterize a new mixed-risk distribution of the total number of Bernoulli outcomes (e.g, failures) for non-homogenous dichotomous events sampled from J non-identical binomial populations with different rates. The resultant distribution can be significantly non-binomial and non-normal, with corresponding consequences on probability calculations, control chart performance, and so ...

identification of homogenous watershed sub basins allows generalization of environmental study results. for this purpose, first available data for 27 selected watersheds in north alborz regarding 21 variables including physiographic and climatic characteristics was gathered. the most important factors impacting upon soil erosion and sediment yield were equivalent rectangular length, mean annual...

analyzing free riding problem through static games considering homogenous players has been resulted in choosing the free riding strategy as a dominant strategy for the players. in this paper free riding is analyzed through cooperation game imposing non-homogenous players using network models. players would be differentiated by their links with their neighbors in the game. evolutionary game theo...

This paper investigates the vibration of a bar for computing its frequency parameter with interval and fuzzy material properties using fuzzy finite element method. First crisp values of material properties are considered. Then the problem has been undertaken taking the properties as interval and fuzzy. Initially, Young’s modulus and density as material properties have been considered as interva...

The paper presents development and tuning tehniques and solutions for PI and PID controllers, and Takagi-Sugeno fuzzy controllers with PI and PID type dynamics meant for applications which can be characterised with low order benchmark type modeles (for example electrical and hydraulic driving and positioning systems).Two type of plants and two control structures with homogenous and with non-hom...
