In previous work, we considered a four-quadrant Riemann problem for 2×2 hyperbolic system in which delta shock appears at the initial discontinuity without assuming that each jump of data projects exactly one plane elementary wave. this paper, consider case does not involve discontinuity. We classified 18 topologically distinct solutions and constructed analytic numerical case. The show rich st...

A low-voltage, low-power analog multiplier operating at 1.2 V is presented. The multiplier i,s composed of a pair of voltage-to-current converters and a pair of voltage followers. The current produced is then added in resistors to produce the voltage output. The circuit rnultiplies the incoming 900 MHz RF signal with an 800 MHz local oscillator signal to produce a 100 MHz IF output. The circuit...

We present a mixed-signal distributed VLSI architecture for massively parallel array processing, with fine-grain embedded memory. The three-transistor processing element in the array combines a charge injection device (CID) binary multiplier and analog accumulator with embedded dynamic random-access memory (DRAM). A prototype 512 128 vector-matrix multiplier on a single 3 mm 3 mm chip fabricate...

In this paper, a single precision IEEE 754 floatingpoint multiplier with high speed and low power is presented. The bottleneck of any single precision floating-point multiplier design is the 24x24 bit integer multiplier. Urdhava Triyakbhyam algorithm of ancient Indian Vedic Mathematics is utilized to improve its efficiency. In the proposed architecture, the 24x24 bit multiplication operation is...

Switched-capacitor (SC) signal processing, :ing a sampled-data, analog-circuit technique, has a natural affinity to multiple-valued logic (MVL). Its simplicity in creating and manipulating signedsignals (in the form of voltage or charge) in any desired radix makes the SC topology a unique circuit technique for MVL implementation, especially when the base value is relatively high. In this paper,...

Emphasizing differences in activation as well as valence, six studies across a range of situations examined relations between types of job-related core affect and 13 self-reported work behaviours. A theory-based measure of affect was developed, and its four-quadrant structure was found to be supported across studies. Also consistent with hypotheses, highactivation pleasant affect was more stron...
