چکیده

This article deals with a possibility of how to determine a power dissipation in a rotating machine. It divides losses in three parts according to their origin – losses arising around the rotating disc, in bearings, and by a friction of a shaft surface due to viscosity. A precise determination of the power dissipation is important when evaluating the efficiency of the whole device. The procedure is graphically illustrated on the example of a single-stage experimental turbine.

Bit Swapping Linear Feedback Shift Register For Low Power Application Using 130nm Complementary Metal Oxide Semiconductor Technology (TECHNICAL NOTE)

Bit swapping linear feedback shift register (BS-LFSR) is employed in a conventional linear feedback shirt register (LFSR) to reduce its power dissipation and enhance its performance. In this paper, an enhanced BS-LFSR for low power application is proposed. To achieve low power dissipation, the proposed BS-LFSR introduced the stacking technique to reduce leakage current. In addition, three diffe...

The Effect of DTMOS Transistors on the Performance of a Memristor-based Ternary CAM Cell in Low Power Applications

This paper proposes the use of DTMOS transistors in a memristor-based ternary CAM (MTCAM) instead of MOSFET transistors. It also evaluates the effect of forward body biasing methods in DTMOS transistors on the performance of a MTCAM cell in write mode. These biasing methods are gate-to-body tying (called DT1), drain-to-body tying (called DT2), and gate-to-body tying with a voltage supply of 0.1...
