Enhancing the output power of a nanogenerator is essential in applications as a sustainable power source for wireless sensors and microelectronics. We report here a novel approach that greatly enhances piezoelectric power generation by introducing a p-type polymer layer on a piezoelectric semiconducting thin film. Holes at the film surface greatly reduce the piezoelectric potential screening ef...

Fast binary translation is a key component for many modern software techniques. This paper reflects on the implementation of fastBT, a generator for low-overhead, tablebased dynamic (just-in-time) binary translators. We discuss the most challenging sources of overhead, propose optimizations to further reduce these penalties, and present a detailed performance analysis with different approaches ...

Humidity measurement is an important technique for the agricultural, foods, pharmaceuticals, and chemical industries. For the sake of convenience, electrical relative humidity (RH) sensors have been widely used. These sensors need to be calibrated to ensure their accuracy and the uncertainty measurement of these sensors has become a major concern. In this study, a self-made divided-flow generat...

The permanent magnet synchronous motors (PMSM) are used as servo motor for precise motion control and are used as generator to generate electrical energy driven by wind energy. There is large variation in inertia due to varying load and parametric uncertainty in PMSM. The design objective of this paper is to analytically determine the relative robust stability of PMSM with parametric uncertaint...

A parity-check matrix for a q -ary repeated-root cyclic code is derived using the Hasse derivative. Then the min imum distance of a q-ary repeated-root cyclic code C is expressecin terms of the min imum distance of a certain simple-root cyclic code C that is determined by C. With the help of this result, several binary repeated-root cyclic codes of lengths up to n = 62 are shown to contain the ...

BACKGROUND Overall and left temporal scalp area reductions of P300 have been demonstrated in schizophrenia. P300 amplitude and topography in psychotic affective disorder, a crucial comparison in assessing the specificity of P300 abnormalities to schizophrenia, are not well studied. METHODS P300 was recorded from 35 schizophrenic, 20 psychotic manic, and 30 control subjects. All were right-han...

This paper provides a detailed analysis that shows how to stabilize the generalized Schur algorithm, which is a fast procedure for the Cholesky factorization of positive-definite struc-tured matrices R that satisfy displacement equations of the form R-FRF T GJGT, where J is a 2 x 2 signature matrix, F is a stable lower-triangular matrix, and G is a generator matrix. In particular, two new schem...

We study the problem of scheduling a hybrid wind-conventional generator system to make it dispatchable, with the aim of profit maximization. Our models ensure that with high probability we satisfy the day-ahead energy promised by the model, using combined output of the conventional and wind generators. We consider two scenarios, which differ in whether the conventional generator must commit to ...

Turbulence is one of the hydraulic disturbances implicated in thrombus formation, even though absolute proof of its contributory effect is lacking. Because of the importance of a possible effect of turbulence on thrombus formation, the relation was studied in eight dogs. In each dog, two arteriovenous shunts were established, one from each femoral artery to the contralateral femoral vein. Only ...
