To proof low voltage techniques are valid in current conveyor design, Bulk driven and composite transistor (self cascode) techniques are used to get high performance results from CCII in low voltage supply. Conventional operational amplifier circuit from literature was our choice as core of the design. Our Focus with using low voltage techniques is study the frequency characteristics of a CCII ...

The flow which constitutes the conveyor belt in the Hamburg large-scale geostrophic ocean general circulation model has been investigated with the help of a particle tracking method. In the region of North Atlantic Deep Water formation a thousand trajectories were calculated backward in time to the point where they upwell from the deep ocean. Both the three-dimensional velocity field and convec...

The objective of this study involves the optimise process of a sorting machine for spherical fruits, which are currently manually classified with a low level of efficiency in Iran. An instrumentation system is modelled and fabricated for the development of a fruit sorting machine. Mechanical components and control system are assembled on a chassis for fruit transferring and classifying. A gravi...

The quest for a useful design tool that incorporated the effect of dynamics of conveyor belts on the design of a conveyor system started halfway the 1950's. It was however not until halfway the 1980's that the first useful design tool became available. In the early days of using dynamics of belt conveyor systems the attention was focused on an analysis of both the starts and the stops of long o...

The performance of the pneumatic servo systems improved greatly as the pneumatic servo valves became commercially available in the late 1980s. At present, one of the best pneumatic servo valves has a dynamic response of 100 Hz and a spool position accuracy of 2% to the full stroke. By using these pneumatic servo valves, the precise position control by the pneumatic servo system has entered a pr...

Based on flexible pneumatic bending joint and flexible pneumatic spherical joint, a kind of flexible pneumatic 5-DOF finger is proposed, which is composed of two bending joints and a spherical joint. The mathematic model of flexible pneumatic spherical joint is further analyzed. On the researching foundation of flexible pneumatic bending joint and flexible pneumatic spherical joint, the kinemat...

Development of automation and robotization in manufacturing process stimulates interest in pneumatic servo-systems whose advantages include low manufacturing costs, high dynamics and reliability (Situm et al., 2004). Unsatisfactory positioning accuracy of multiaxis pneumatic servosytems considerably reduces their application in manipulating machines, manipulators and robots. Rapid advance in pa...

Abstract: A simple topology for the realization of negative type differential difference current conveyor (DDCC-) is presented. The proposed topology is based on floating output transconductor (FOT) circuits. A CMOS realization of this type current conveyor, which is made up from floating current sources (FCS), is given. Design details and simulation results using PSPICE are given to verify pre...
