The purpose of this paper is to exhibit an explicit formula which describes the projection operator from the space of C°° automorphic forms to the subspace of holomorphic cusp forms, and to apply it to the zeta functions of Rankin type. Fix a number k > 0 such that 2k G Z. Let TV be a positive integer such that TV = 0 mod(4) if k fi Z, and let x(Z/NZ) —+ C be a Dirichlet character modulo TV. De...

In this study, dynamic behavior of safety mechanism of a mechanical controller is investigated using 3D-FE simulation. This paper is concentrated on controller of a high acceleration projectile. The controller is located in the top of the projectile. Safety mechanism is divided to deformable and rigid parts. Deformable and rigid parts are simulated in Abaqus and Adams commercial soft wares; res...

This paper proposes a new sliding mode control (SMC)  based model reference adaptive system (MRAS) for sensorless indirect field oriented control (IFOC) of a single-sided linear induction motor (SLIM). The operation of MRAS speed estimators dramatically depends on adaptation mechanism. Fixed-gain PI controller is conventionally used for this purpose which may fail to estimate the speed correctl...

in this study, dynamic behavior of a controller's self destruction mechanism has been simulated using 3d-fem in adams software and investigated. this paper has been concentrated on high acceleration controller's projectiles. this controller is mechanical and has been placed in top of the projectile. the goal of this study is to investigate the destruction mechanism operation i.e. movement of pi...

mechanical weeding is one of the non-chemical methods to control weeds. in this paper a ‎new mechanism has been presented for mechanical cultivation. the machine works based on ‎the manual tools operation, which farmers still use in small scale for weeding and consists of a ‎number of four-bar linkage mechanisms. each mechanism consists of a blade which moves ‎forward (active course) and backwa...

disk plows are one of the most important tillage tools. two way (reversible) disk plows can perform continues plowing. so they can save time and costs and hence improve overall efficiency. in this study, a “two-way” disk plow was designed based on a λ-formed straight-line, four-bar linkage (daniel mechanism). this design contains disk and rear wheel reversing mechanism, stabilization mechanism ...
