Network properties of salmonella epidemics

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Epidemics on social network graphs

This work is concerned with relaxing the assumption of homogeneous mixing in a Reed-Frost epidemic model. After a thorough presentation of the standard Reed-Frost model we introduce social structure in the population by aid of a social network graph and investigate the effects on the epidemic spread. A number of possible choices for the underlying social network are presented: Bernoulli graphs,...

SIRS Model For The Dynamics Of Non-Typhoidal Salmonella Epidemics

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Salmonella senftenberg: epidemics in India and present status.

Salmonella enterica serover Senftenberg (Salmonella senftenberg: l,3,19:g,[s],t:-) was first isolated by Kauffmann in 1928 from the stool of an 8 years old male child with acute gastroenteritis, at Senftenberg Hospital, Berlin, Germany(l). Since then, this organism has been reported in more than 30 countries with most isolations from the Netherlands, England, Germany, USA, Australia, India, Isr...
