Modern vehicles are equipped with many systems that monitor the security of driving. An example is tyre pressure monitoring system shows a fault if lowered. Low or no at all (0 kPa) means continuing driving may lead to dangerous situation. Prolonged vehicle 0 kPa in ends burst, rim damage, even loss stability. Therefore, on automotive market, manufacturers offer Run Flat tyres adapted emergency...

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. ...

Two new types of floating current conveyors are introduced. Each type has four ports: Y , X and two Z ports. The first type is the Floating Second Generation Current Conveyor (FCCII) and includes both CCII+ and CCII− as special cases. The second type is the Floating Inverting Second Generation Current Conveyor (FICCII) and includes both ICCII+ and ICCII− as special cases. The Nodal Admittance M...

This paper is a tutorial introduction to field-programmable analog arrays, as well as a review of existing field-programmable analog array architectures, of both educational and industrial origin. Circuit issues relevant to the development of high-bandwidth FPAAs are presented. A current conveyor-based architecture, which promises to achieve video bandwidths, is described. Test results are pres...

BACKGROUND To examine Chinese soldiers' acute stress responses, we did this study. METHODS The soldiers completed the Acute Stress Response Scale (ASRS) when engaged in major tasks, such as earthquake rescue in Wenchuan, Sichuan, and maintaining social stability in Urumchi, Xinjiang. The ASRS has good reliability and validity. The study enrolled 1,832 male soldiers. RESULTS The results show...

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 ...

The cosmic acceleration is one of the most significant cosmological discoveries over the last century. The two categories of explanation are exotic component (dark energy) and modified gravity. We constrain the two types of model by a joint analysis with perturbation growth and direct H(z) data. Though the minimal χ of the ΛCDM is almost the same as that of DGP, in the sense of consistency we f...

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...
