Abstract. Surface flow on rilled hillslopes tends to produce sediment yields that scale nonlinearly with total hillslope length. The widespread observation lacks a single unifying theory for such nonlinear relationship. We explore the contribution of rill network geometry observed yield–length scaling Relying an idealized geometry, we formally develop probability functions geometric variables c...
front end یک رادار باند (f=9.4ghz)x به صورت (microwave integrated circuits)mic طراحی، ساخته و اندازه گیری شد . تقویت کننده کم نویز مدار یک تقویت کننده بالانس می باشد که ترانزیستورهای آن gaasmesfet به صورت چپ می باشند. بهره تقویت کننده در فرکانس 9.4ghz برابر 13db و عدد نویز آن 3db اندازه گیری می باشد . میکسر مدار، یک میکسر دیودی به صورت تک بالانس بوده و هایبرید 180 درجه آن از نوع حلقه (ratrace) ...
conclusions we report of loss of achieved length after lengthening with a telescopic nail. weight bearing before complete consolidation of the regenerate might be a risk factor for that. thorough examination of the limb length and careful evaluation of the radiographs are required in the follow-up period. the precice nail system requires the same vigilance like the other intramedullary systems ...
abstract many studies have been conducted on the characteristics of hydraulic jump over gradually expanding cross sections, but comparatively few have been carried out on basins with convergent wall. in the present research, the hydraulic jump characteristic of the stilling basin with convergent wall has been investigated. the main objective of this research is evaluation of conjugate depths ra...
this paper presents a discrete-time single-server finite buffer n threshold policy queue with renewal input and discretemarkovian service process. the server terminates service whenever the system becomes empty, and recommencesservice as soon as the number of waiting customers in the queue is n. we obtain the system-length distributionsat pre-arrival and arbitrary epochs using the supplementary...
the modeling can provide a quantitative approach and consistency in the estimationsoil erosion and sediment yield by a wide range of conditions. in this study, the integration method of revised universal soil loss equation model, geographic information system and remote sensing techniques were used in order to identify the spatial distribution of soil erosion and sediment yield in the talar wat...
Background : Although factors such as implant length, location, and diameter as well as bone quality have been associated with excessive failure rates, smoking is suggested as a stronger predisposing factor for higher failure rates. Thus, knowing the relationship between bone loss around the dental implants, maintenance of the implants and smoking could be a principle step towards solving the...
