Controlling the occurrence of defects is a major challenge for manufacturing organizations that are seeking to enhance their competitive position in today’s global market. This paper considers the process of screen-printing T-shirts using hydraulic and pneumatic printing machines. Several defects in the output of this printing process have been observed, especially with multi colors printing as...

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...

ZERO SPEED OR MOTION DETECTION Motion detection is a valuable resource for improving productivity in many plants. As production speeds increase and more sophisticated assembly lines and conveyor systems are used, there is a greater need to monitor and control conveyor speed. This is particularly true since there are more motors, transmissions and belts that can fail, causing the system to halt....

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...

The development of knowledge-based systems (KBS) enables accumulated experience and knowledge to be applied to the intelligent monitoring in the field of large-scale belt conveyor systems. The first step of building knowledge bases in a KBS is referred to the knowledge acquisition (KA). KA from domain experts and field experiments has often been considered as the most difficult task and time-co...

This paper introduces a new type of CMOS-based current conveyor: current controlled fully balanced second generation current conveyor (CFBCCII) element which has a pair of differential Y terminals, a pair of differential X terminals and two pairs of Z terminals. The proposed circuit offers electronic tuning possibilities by means of a current adjustable intrinsic resistance at its X terminal. A...

Field Programmable Mixed-Signal Arrays (FPAA) designs are reviewed and standard building blocks described with respect to circuit parameters and design limitations. The second-generation current conveyor is introduced as an analog building block with properties similar to those of an operational amplifier, and which has the potential for high frequency operation. A current conveyor can be imple...

BACKGROUND Pneumatic dilatation or intrasphincteric botulinum toxin injection provide effective symptom relief for patients with achalasia. Although intrasphincteric botulinum toxin injection is simple and safe, its efficacy may be short-lived. Pneumatic dilatation lasts longer, but esophageal perforation is a risk. We compared treatment costs for pneumatic dilatation and intrasphincteric botul...
