با توجه به اهمیت تحلیل هیدرولیکی جریان غیردائم در مجاری بسته، کاربرد روش های حل عددی پیشرفته و به منظور حل معادلات کامل حاکم بر اینگونه جریان ها (معادلات saint - venant) مورد توجه جدی قرار گرفته اند. از میان روش های حل عددی موردنظر، الگوی چهار نقطه ای preissmann بدلیل پایداری عددی و تطابق خوب آن با واقعیت در سطح وسیعی مورد استفاده قرار گرفته است . از طرف دیگر تحلیل اینگونه جریان ها تحت شرایط تو...
This paper describes several unexpected benefits of rodenticide-registration research funded by The California Bait Surcharge Program. An enclosure-type study was conducted to determine efficacy of single, preand test-bait broadcasts (10 lb./ac.) of 0% and 2% zinc phosphide (ZqP,, CAS #1314-84-7) steam-rolled-oat (SRO) groats to control voles (Microtus spp.) in alfalfa (Medicago sariva). Unexpe...
Single Photon Detector and adopted ALV-7004/USB MultipleTau Correlator plus ALV-Correlator Software for WIN-7/8 (32/64 bit) Optimized optical input for Single Mode Fibres via FC/PC socket High quantum efficiency with a PDE of up to 60% peak and 40% at 532 nm wavelength Superior high count rate linearity with a limiting count rate exceeding 80 Mcps Lowest self-correlation contribution allows sub...
Studies on the propagation of malware in mobile networks have revealed that the spread of malware can be highly inhomogeneous across different regions. Heterogeneous rates of contact can also be due to diverse platforms, utilization of contact lists by the malware, the clustered nature of the network, etc. In this paper, a general formal framework is proposed for leveraging such information abo...
Some new Advanced Driver Assistance Systems (ADAS) need on-the-lane vehicle positioning on accurate digital maps, but present applications of vehicle positioning do not justify the surcharge of very accurate equipment such as DGPS or high-cost inertial systems. For this reason, performance of GPS in autonomous mode is analyzed. Although satisfactory results can be found, in some areas GPS signa...
This study developed a model with cost functions formulated for different stages of cargo transport operation. A case analysis was performed with actual data from four air cargo traffic routes and eight aircraft types to validate the applicability of the model. The results show that the optimal payloads for various aircraft types vary with fuel price fluctuations. Furthermore, this study determ...
This paper elucidates the methodology of applying artificial neural network model (ANNM) to predict the percent swell of calcitic soil in sulphuric acid solutions, a complex phenomenon involving many parameters. Swell data required for modelling is experimentally obtained using conventional oedometer tests under nominal surcharge. The phases in ANN include optimal design of architecture, operat...
RÉSUMÉ. Dans le contexte actuel de surcharge d’informations, les utilisateurs peuvent s’en remettre à des systèmes de filtrage qui leur recommandent en permanence, en se basant sur leur profil, des informations vraisemblablement pertinentes. Néanmoins, un changement dans leur besoin d’information n’est pas toujours bien pris en compte à cause du rôle relativement passif des utilisateurs dans la...
