with the establishment of modern bureaucracy in iran, it was expected that the administrative system would find a logical order based on legal rationality. this not only proved to be far from the case, but the administrative system showed an unfortunate return to its previous status as well. the efforts made to improve the system have only aggravated the situation. the first question addressed ...

We study an automata-theoretic approach to planning for temporally extended goals. Specifically, we devise techniques based on nonemptiness of Büchi automata on infinite words, to synthesize sequential and conditional plans in a generalized setting in which we have that: goals are general temporal properties of desired execution; dynamic systems are represented by finite transition systems; inc...

Cystic Hygroma is a well-recognized lesion in paediatric patients but it is very rare in adults. We report here a case of Cervical Cystic Hygroma in a 45 yr old male. The reasons to present this case are 1) Its rarity in adults 2) Unusual age of presentation 3) Simulates various benign and malignant lesions at this site 4) Is a diagnostic challenge and 5) Role of histology for definitive postop...

in this paper, we use parametric form of fuzzy number and we converta fuzzy linear system to two linear system in crisp case. conditions for the existence of a minimal solution to $mtimes n$ fuzzy linear equation systems are derived and a numerical procedure for calculating the minimal solution is designed. numerical examples are presented to illustrate the proposed method.

Congenital methemoglobinemia is a rare cause of cyanosis. We report a case of a girl, 17 years old with peripheral cyanosis and normal cardio-pulmonary system. She was diagnosed as a case of methemoglobinemia based on findings of polycythemia and HbM band on hemoglobin electrophoresis. We emphasize the importance of this rare entity in the differential diagnosis of cyanosis.

In this article our objective is to obtain steady state characteristics of shunt, series, and separately excited DC motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. We assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. It is ...
