The in-plane and cross-plane thermal conductivities of the cladding layers and active quantum wells of interband cascade lasers and type-II superlattice infrared detector are measured by the 2-wire 3ω method. The layers investigated include InAs/AlSb superlattice cladding layers, InAs/GaInSb/InAs/AlSb W-active quantum wells, an InAs/GaSb superlattice absorber, an InAs/GaSb/AlSb M-structure, and...
The populations of cave-dwelling bat species are encountering a remarkable decline all over the world. To plan effective conservation projects for bats and their cave roosts, collecting data on distribution in particular region is essential. Furthermore, developing an applicable index that incorporates both biotic abiotic parameters relevant to caves useful prioritize management. Recently, ther...

مساله مکان?یابی ماکزیمم پوشش از جمله پرکاربردترین مسائل مکان?یابی محسوب می شود. در این مساله هدف تعیین مکان p مرکز سرویس و تخصیص نقاط تقاضا به آنها به گونه ای است که جمعیت سرویس داده شده ماکزیمم شود. یک از معیارهایی که موجب افزایش کیفیت خدمات رسانی توسط مراکز سرویس می شود، توجه به میانگین زمان انتظار در مراکز سرویس می باشد. در این رساله سه مساله مکان یابی ماکزیمم پوشش مورد بررسی قرار می گیرد....
In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...
non-commercial fish species of shrimp trawls were studied monthly from october 2005 to september 2006 in mahshahr creeks (darvish, doragh, bihad, ghazaleh, ghanam, zangi and patil). the trawl nets had a cod-end mesh size of 24mm. total catch was 6431 individuals weighing 55.5kg, and included 14 species of non-commercial fish species belonging to 14 families. the caught shrimp species were from ...

The object of the investigation is to study reducible $M$-ideals in Banach spaces. It is shown that if the number of $M$-ideals in a Banach space $X$ is $n(<infty)$, then the number of reducible $M$-ideals does not exceed of $frac{(n-2)(n-3)}{2}$. Moreover, given a compact metric space $X$, we obtain a general form of a reducible $M$-ideal in the space $C(X)$ of continuous functions on $X$. The...
