Digital signal processors (DSP) are widespread in real-time systems. In the last ten years phase-locked loops have widely been used in DSP as control devices correcting a clock skew. In this paper new type of floating phase locked loops for DSP is designed. For the floating phase locked loops new stability conditions are obtained.

Using ion-exchange resins, a multiple-unit type of oral floating dosage system has been prepared to prolong gastric emptying time of dosage form. The system is composed of beads of drug-resin complex, which are loaded with bicarbonate ions and coated with a hydrophobic polymer. The system is so designed that when the beads reach the stomach, chloride ions are exchanged with bicarbonate and drug...

in this paper the separation of saffron stigma from stamen and petal in a vertical wind tunnel has been evaluated. a wind tunnel with adjustable speed of 0.1 m s-1 intervals has been developed and used for the experiments. floating velocities of flower components (petal, stigma and stamen) were measured at one, eight, 38 and 60 hours after harvesting. subsequently, the separation was tested by ...

Thirty seven cases of coronary heart disease and 30 normal healthy controls were administered Hindi version of MHQ. The coronary heart disease patients scored significantly higher on total neuroticism, free-floating anxiety and somatic anxiety subscales of MHQ.

This paper describes the architectural extensions to the PA-RISC 1.1 architecture to enable 64-bit processing of integers and pointers. It also describes MAX, the Multi-media Acceleration eXtensions which speed up the processing of multimedia and other applications with parallelism at the intra instruction, or subword, level. Other additions to the PA-RISC 2.0 architecture include performance e...

Field Programmable Gate Arrays (FPGAs) are frequently used to accelerate signal and image processing algorithms due to their flexibility, relatively low cost, high performance and fast time to market. For those applications where the data has large dynamic range, floating-point arithmetic is desirable due to the inherent limitations of fixed-point arithmetic. Moreover, optimal reconfigurable ha...

This paper presents a low-cost, single-cycle floating-point unit developed for digital audio processing applications. In the unit, the serial steps of floating-point operations are paralleled to reduce critical path delay, and hardware resources are shared with the integer datapath to minimize area overhead. Its area overhead is as small as 38% of the fixed-point datapath, and the critical path...

background: breast cancer is one of the most prevalent malignancies among women in various countries. her2 overexpression, which is due to different reasons, occurs in 20-30% of breast cancers. her2 gene encodes an 185kda transmembrane glycoprotein with 1255 amino acids. this active product triggers downstream intracellular signaling pathways inducing cell proliferation and cell survival. these...
