In this paper, we study disassembly sequencing flexibility that means the possibility of interchanging the order in which the required disassembly operations are performed. A mathematical model to design joint cellular disassembly systems is proposed, in which the trade-off of throughput time performances between the case of considering and the case of not considering disassembly sequencing fle...

veyor. I,,, = Z,,(jw) is also the phasor current through the x terminal of the lsth current conveyor. V,,,, Vtzk and I,,h are the bounds of the linear region obtained from the transfer characteris tics or from the linear operation conditions, and these are termed the saturation voltages and current of the kth current conveyor. When the CCIIs are implemented using the above mentioned CMOS config...

We experimentally demonstrate a class of tractor beams created by coherently superposing coaxial Bessel beams. These optical conveyors have periodic intensity variations along their axes that act as highly effective optical traps for micrometer-scale objects. Trapped objects can be moved selectively upstream or downstream along the conveyor by appropriately changing the Bessel beams' relative p...

For the special working environment and conveyor as diagnostic object, this paper proposed a new fault diagnosis method based on ontology to diagnose the fault of conveyor as follows: stalling, drifting and damage. The experiment results show that: the proposed fault diagnosis method avoids the weakness of former methods, could diagnose all kinds of fault phenomenon and different fault causes. ...

There has been increased interest in use of pneumatic actuators in many fields, such as medical care and welfare. In particular, proposed pneumatic soft actuator with soft material has many advantages such as low mass, flexibility, safety and user-friendliness. We therefore focus on the pneumatic actuators as a drive source of a rehabilitation device. This paper describes the concept, design, p...

In this paper, a systematic design method producing balanced current-mode filters is proposed, using current controlled fully balanced second-generation current conveyor circuit (CFBCCII). In this method, many kind of all-pole multiple loop feedback (MF) current mode balanced filters can be obtained, all the produced filters have fully balance structures. Moreover, the frequency of the filters ...

Semiconductor industry has tremendous development in recent decades. According to Moore’s Law [1], semiconductor wafer manufacturers have to search improvement opportunities constantly in order to be competitive. International technology roadmap for semiconductor [2] has indicated the possible scenarios for 450 mm wafer fabs, and the conveyor will be a potential solution to realize transportati...

This paper discusses automation of maintenance of belt conveyor systems, in particular of idler rolls. Automation of maintenance is a promising alternative for outsourcing maintenance, in particular when looking at the efficiency, accuracy, and costs. In order to optimise maintenance efforts, the concept of intelligent maintenance is introduced. The powered maintenance trolley that can travel a...

The paper presents a current conveyor based multifunction filter. The proposed circuit can be realized as low pass, high pass, band pass and elliptical notch filter. The circuit employs two balanced output current conveyors, four resistors and two grounded capacitors, ideal for integration. It has only one output terminal and the number of input terminals may be used. Further, there is no requi...

We consider the movement minimization problem in a conveyor flow shop processing controlled by one worker for all machines. A machine can only execute tasks if the worker is present. Each machine can serve as a buffer. The worker has to cover a certain distance to move from one machine to the other. The distance between two machines Pp and Pq is jp qj. The objective is to minimize the total dis...
