In this work, we present new topologies for realizing one lossless grounded inductor and two floating, one lossless and one lossy, inductors employing a single differential difference current conveyor (DDCC) and a minimum number of passive components, two resistors, and one grounded capacitor. The floating inductors are based on ordinary dual-output differential difference current conveyor (DO-...

The well known problem of priority inversions that occurs in classical real-time systems also manifests in decentralized cyber-physical systems. Using a specific example of composable conveyor systems, we show how priority inversions hinder the transport of entities through the conveyor systems. We present a novel adaptation of the classical priority inheritance protocol for resolving these cyb...

Many problems which occur with belt conveyors can be attributed to system dynamics and the associated variations in belt tension. Material spillage, belt and splice failure, belt lift-off in vertical curves and poor tracking are a few examples of situations where knowledge of the dynamic tensions would be of benefit in eliminating a problem. The difficulty is that measuring dynamic tension at a...

The paper presents a current tunable multifunction filter using current conveyor. The proposed circuit can be realized as on chip tunable low pass, high pass, band pass and elliptical notch filter. The circuit employs two current conveyors, one OTA, four resistors and two grounded capacitors, ideal for integration. It has only one output terminal and the number of input terminals may be used. F...

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. ...

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...
