Introduction: Background: Radiotherapy of parotid tumors is achieved by different radiotherapy techniques. So they deliver the dose to organs at risk such as contralateral parotid, temporal lobe & spinal cord. The consequences of high dose to OARs are xerostomia, Temporal lobe necrosis and loss of hearing. Purpose: The aim of this study was to compare different treatment tech...

Investment strategy is often static, punctuated by infrequent reviews. For most long-term investors, this practice results in large risks being taken that could otherwise be managed with a more dynamic investment policy. The bulk of this paper is aimed at analysing and describing two multi-period investment strategy problems – in order to derive potential dynamic strategies. Along the way, we s...

The verification of the self-stabilization property of a distributed algorithm is a complicated task. By exploiting certain analogies between self-stabilizing distributed algorithms and globally asymptotically stable feedback systems, techniques originally developed for the verification of feedback system stability can be adopted for the verification of selfstabilization of distributed algorith...

in this research, first, kinematic and dynamic equations of a 4-dof 3-link robotic finger are derived using denavit-hartenberg convention and lagrange’s formulation. to model the muscles, several springs and dampers are placed between the finger links. then, two advanced controllers, namely adaptive-robust and adaptive-neural, which can control the robotic finger in presence of parametric uncer...

SQL statements control the bi-directional data flow between application programs and a database through a high-level, declarative and semantically rich data manipulation language. Analyzing these statements brings invaluable information that can be used in such applications as program understanding, database reverse engineering, intrusion detection, program behaviour analysis, program refactori...

As customers are the main asset of any organization, customer churn management is becoming a major task for organizations to retain their valuable customers. In the previous studies, the applicability and efficiency of hierarchical data mining techniques for churn prediction by combining two or more techniques have been proved to provide better performances than many single techniques over a nu...

There is no review paper available on Artificial Intelligence (AI) applications to e-commerce to the best of knowledge. This paper is a survey of various AI techniques that are used in the design and development of ecommerce systems. The techniques are categorized into three groups namely, AI techniques for B2B ecommerce, AI techniques for B2C e-commerce, and AI techniques for both B2B and B2C ...

A recursive dynamic modeling of a three-DOF parallel robot, namely, threeRevolute-Prismatic-Spherical (3-RPS) parallel manipulator is reported in this work. Euler parameters are utilized to define the 3-DOF orientation of its moving platform, because the coordinates are free of singularity. For the dynamic modeling, the concept of the Decoupled Natural Orthogonal complement (DeNOC) matrices is ...
