این رساله به بررسی دو حالت متفاوت مسئله پوشش کامل هدف در شبکه های حسگر بصری پرداخته است. هدف هر دو مسئله بیشینه کردن طول عمر شبکه می باشد. درحالت اول مسئله یعنی پوشش بصری اهداف (visual target coverage -vtc) راه حلی برای قرارگیری بهینه حسگرها در منطقه مورد نظر بدون در نظر گرفتن اتصال بین حسگرها برای یک شبکه همگن حسگر بصری پیشنهاد شده است. در حالت دوم مسئله به نام پوشش پیوسته بصری اهداف(connected...
Abstract Given the importance of water resources in sustainable development, it is necessary to investigate the direct and indirect impacts of inter-basin water transfer projects. The present research analyzed the status of the water resources in the south of Kerman province and the challenges of inter-basin water transfer that will result from transferring water from the upstream Halilroo...
the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
The purpose of this paper is to provide a new algorithm for guidance of an underwater vehicle to reach its target, and demonstrate its effectiveness by simulation with a computer code. The meant of target in here is to chase a ship on the surface of the water. In order to do this, one of the most effective methods is to follow the ship wake which produced behind it. Disadvantages of wake guidan...
objective(s):an earlier meta-analysis on gene expression data derived from four microarray, two cdna library, and one sage experiment had identified rgs5 as one of only ten non-housekeeping genes that were reported to be expressed in human trabecular meshwork (tm) cells by all studies. rgs5 encodes regulator of g-protein signaling-5. the tm tissue is the route of aqueous fluid outflow, and is r...
the current building codes provide limited prescriptive guidance on design for protection of buildings due to progressive collapse. progressive collapse is a situation in which a localized failure in a structure, caused by an abnormal load, such as explosions or other happenings. three procedures, often employed for determination of the structural response during progressive collapse i.e. linea...
This paper investigates an underwater noise target classification algorithm in order to identify vessels in shallow water. To this aim the Hilbert Huang transform has been used to extract features in order to be used in a classifier. The Support Vector Machine has been considered to identify targets. The proposed method based on Hilbert Huang Transform shows considerable gain against similar ap...
The productive cellulosic crops switchgrass and Miscanthus are considered as viable biofuel sources. To meet the 2022 national biofuel target mandate, actions must be taken, e.g., maize cultivation must be intensified and expanded, and other biofuel crops (switchgrass and Miscanthus) must be cultivated. This raises questions on the use efficiencies of land and water; to date, the demand on thes...
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
