In this paper, we propose and validate a novel design for a double-gate tunnel fi eld-effect transistor (DG Tunnel FET), for which the simulations show significant improvements compared with single-gate devices using an SiO2 gate dielectric. For the fi rst time, DG Tunnel FET devices, which are using a high-κ gate dielectric, are explored using realistic design parameters, showing an ON-current...

jachymski [ proc. amer. math. soc., 136 (2008), 1359-1373] gave modified version of a banach fixed point theorem on a metric space endowed with a graph. in the present paper, (g, φ)-graphic contractions have been de ned by using a comparison function and studied the existence of fixed points. also, hardy-rogers g-contraction have been introduced and some fixed point theorems have been proved. s...

The Longest common subsequence problem is examined from the point of view of parameterized computational complexity. There are several diierent ways in which parameters enter the problem, such as the number of sequences to be analyzed, the length of the common subsequence, and the size of the alphabet. Lower bounds on the complexity of this basic problem imply lower bounds on a number of other ...

We characterize the polynomial time computable queries as those ex pressible in relational calculus plus a least xed point operator and a total ordering on the universe We also show that even without the ordering one application of xed point su ces to express any query expressible with several alternations of xed point and negation This proves that the xed point query hierarchy suggested by Cha...

© 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Vertically aligned carbon nanotube (CNT) forests may be used as miniature springs, compliant thermal interfaces, and shock absorbers, and for these and other applications it is vital to understand how to engineer their mechanical properties. Herein is investigated how the diameter and packing density within CNT forests govern their deformation b...

Recently introduced frequency modulation (FM) systems provide an adaptive adjustment to the emphasis of the FM system through the user’s hearing aid via VoicePriority iTM (VPi). VPi measures the noise level at the listener’s hearing aid microphone and adds gain to the FM signal when the background noise increases to a detrimental level. However, the potential benefi t of VPi technology has yet ...

We study a class of discrete dynamical systems that is motivated by the generic structure of simulations. The systems consist of the following data: (a) a ®nite graph Y with vertex set f1; . . . ; ng where each vertex has a binary state, (b) functions Fi : F2 ! F2 and (c) an update ordering p. The functions Fi update the binary state of vertex i as a function of the state of vertex i and its Y-...

Speech recognition in quiet and in noise was evaluated for children with normal hearing, children with hearing loss, and adults with normal hearing. Performance was evaluated in a classroom environment without use of wireless radio frequency (RF) hearing assistance technology (HAT) and with two different types of classroom audio distribution (CAD) systems (a fi xed-gain multiple loudspeaker sys...

The paper aims to outline the author impact based on Lotka’s Law using R. Lotka’s Law is well known as “the inverse square law of scientifi c productivity.” It states that the number of authors publishing a certain number of articles is a fi xed ratio to the number of authors publishing a single article. The study found authoring patterns do not match to Lotka’s Law. The study summarizes the re...
