به منظور تخمین زمانی- مکانی مقدار بارش ماهیانه، با توجه به پیچیدگی پدیده و در دسترس نبودن اطلاعات فیزیکی کافی و عدم اطلاع دقیق از روابط و معادلات ریاضی حاکم بر مسئله، معمولاً به سراغ ارائ? مدلهای جعبه سیاه، که مستقل از پارامترهای فیزیکی موثر بر پدیده و معادلات حاکم بین آنها می باشد، باید رفت. در این پایان نامه مدلی ترکیبی و جعبه سیاه تحت عنوان ann-rbf به منظور تخمین زمانی- مکانی مقدار بارش ماهی...
Scuba diving is associated with an important risk of developing decompression sickness secondary to formation of gas bubbles inside the body. The latter is formed mainly by nitrogen in the body on the diver’s way to the surface (1,2). In some cases, it might injure the central nervous system. Several decompression cases that have been associated with neurologic symptoms are described in the l...
This paper proposes a benchmark for multi-objective optimization based on video game playing. The challenge is to optimize an agent to perform well on several different games, where each objective score corresponds to the performance on a different game. The benchmark is inspired from the quest for general intelligence in the form of general game playing, and builds on the General Video Game AI...
OBJECTIVE In a sample of older Japanese American women, we aimed to: (1) describe the most commonly consumed soy foods, (2) estimate dietary soy isoflavone intake, (3) describe characteristics associated with dietary soy isoflavone intake, and (4) compare our estimates with previously published estimates in other Japanese samples. DESIGN A 14-item soy food-frequency questionnaire was administ...
Mulibrey nanism (MUL) is a rare autosomal recessive multi-organ disorder characterized by severe prenatal-onset growth failure, infertility, cardiopathy, risk for tumors, fatty liver, and type 2 diabetes. MUL is caused by loss-of-function mutations in TRIM37, which encodes an E3 ubiquitin ligase belonging to the tripartite motif (TRIM) protein family and having both peroxisomal and nuclear loca...
The effects of distinct agent interaction and activation structures are compared and contrasted in several multi-agent models of social phenomena. Random graphs and lattices represent two limiting kinds of agent interaction networks studied, with so-called 'small-world' networks being an intermediate form between these two extremes. A model of retirement behavior is studied with each network ty...
The single vehicle routing problem with multiple routes is a variant of the vehicle routing problem where the vehicle can be dispatched to several routes during its workday to serve a number of customers. In this paper we propose a goal programming model for multi-objective single vehicle routing problem with time windows and multiple routes. To solve the model, we present a heuristic method wh...
There are various landforms in real word and numerous methods proposed previously for DEM generalization. When use different methods to generalize a DEM, the results vary greatly. Therefore, in order to get a most proper method to implement the generalization, we need taking topographic information into consideration. This paper tested four methods widely used in DEM generalization and compared...
1. Animals foraging for resources are under a variety of selective pressures, and separate optimality models have been developed predicting the optimal reproductive strategies they should adopt. 2. In most cases, the proximate behavioural mechanisms adopted to achieve such optimality goals have been identified. This is the case, for example, for optimal patch time and sex allocation in insect p...
