This current work is devoted to develop qualitative theory of existence solution some families fractional order differential equations (FODEs). For this purposes we utilize fixed point due Banach and Schauder. Further using transform method (DTM), also compute analytical or semi-analytical results the proposed problems. Also by proper examples demonstrate results.
In the analysis of terrestrial laser scanning (TLS) data the digital terrain model (DTM) is one of important elements. To evaluate the DTM or to find the DTM by way of optimization it is necessary to formulate the measure of DTM quality. Three parameterized measures are proposed and tested against a comparative model for a series of TLS data. The measure equal to the number of points inside a l...
Differencing between green cover and grape canopy is a challenge for vigour status evaluation in viticulture. This paper presents the acquisition methodology of very high-resolution images (4 cm), using a Sensefly Swinglet CAM unmanned aerial vehicle (UAV) and their processing to construct a 3D digital surface model (DSM) for the creation of precise digital terrain models (DTM). The DTM was obt...
Detailed high-resolution digital terrain models (DTM) can be obtained using airborne laser scanner data. This paper evaluates the accuracy of DTM derived from first return of laser scanner data for forest studies. Study area is located in a boreal forest zone. The data were acquired with TopoSys-1 under leaf-on condition. The study shows that the use of first pulse data for DTM generation in bo...
This paper proposes the use of formal feedback control theory as a way to implement adaptive techniques in the processor architecture. Dynamic thermal management (DTM) is used as a test vehicle, and variations of a PID controller (Proportional-Integral-Differential) are developed and tested for adaptive control of fetch “toggling.” To accurately test the DTM mechanism being proposed, this paper...
در این مقاله امکان استفاده از مشاهدات ماهواره ارتفاع سنجی توپکس – پوزایدون در تهیه DTM خشکی ها مورد مطالعه قرار گرفته است . منطقه جغرافیایی ایران به عنوان نمونه برای این منظور انتخاب و DTM حاصل از ماهواره توپکس – پوزایدون با دو DTM موجود از این منطقه مقایسه گردیده است . بر اساس مطالعات انجام گرفته مشاهدات ماهواره توپکس – پوزایدون می تواند منبع خوبی برای افزایش دقت DTM های موجود و یا افزایش تراک...
In this paper, the differential transformation (DTM) and Adomian decomposition (ADM) methods are proposed for solving fourth order eigenvalue problem. This problem has nonstrongly regular boundary conditions. been examined p(t) = t, B 0, a 0,01 where ≠ 0 is complex valued The briefly described. An approximate solution obtained by performing seven iterations with method. same number of have made...
Distributed Transactional Memory (DTM) is an emerging approach to distributed synchronization based on the application of the transaction abstraction to distributed computation. DTM comes in several system models, but the control flow model (CF) is particularly powerful, since it allows transactions to delegate computation to remote nodes as well as access shared data. However, there are no exi...
In this paper, a novel variant of Differential Transform Method (DTM), Shooting Type Algorithm (STDTA) is used to solve some problems in fluid mechanics with one the boundary conditions at infinity. The analytical solution obtained by using method effective sense that accuracy found more. To apply condition infinity two procedures are used. STDTA an for solving these types
Digital terrain model (DTM) generation is the fundamental application of airborne Lidar data. In past decades, a large body of studies has been conducted to present and experiment a variety of DTM generation methods. Although great progress has been made, DTM generation, especially DTM generation in specific terrain situations, remains challenging. This research introduces the general principle...
