We present a new compact verifiable secret sharing scheme, based on this we present the first construction of a homomorphic UC commitment scheme that requires only cheap symmetric cryptography, except for a small number of seed OTs. To commit to a k-bit string, the amortized communication cost is O(k) bits. Assuming a sufficiently efficient pseudorandom generator, the computational complexity i...

The speed sensorless control of nonsalient PMSM that uses estimated rotor flux instead of the transformation angle is designed. This paper introduces a new sequential switching control strategy for a current control of a three phase inverter. The key idea is to integrate the benefits of the variable structure system control design and the event-driven sequential control structures to raise the ...

This paper focuses on the design of an error feedback sliding mode regulator able to achieve the asymptotic tracking of a reference trajectory for linear systems. It is assumed that the reference trajectory is generated by means of neutrally stable unforced systems. The solution conditions are derived for linear systems presented in general, Regular and Block controllable forms. Copyright © 200...

The authors present a novel approach to control this kind of motor. Modifying published results for nonlinear identification using dynamic neural networks, they propose a new neural network identifier of triangular form. Based on this model a new control law, which combines sliding mode and block control is derived. This new neural identifier and the proposed control law allow trajectory tracki...

PURPOSE Vestibular rehabilitation is an effective intervention for dizziness due to vestibular dysfunction, but is seldom provided. We aimed to determine the effectiveness of an Internet-based vestibular rehabilitation program for older adults experiencing dizziness in primary care. METHODS We undertook a single-center, single-blind randomized controlled trial comparing an Internet-based vest...

We studied the disposition of sufentanil in 10 patients undergoing renal transplantation, and compared the data with those from eight healthy anaesthetized patients undergoing lower abdominal surgery. Patients received sufentanil 2.5 micrograms kg-1 as part of a balanced anaesthetic technique. Central venous blood samples were collected at intervals up to 600 min, and plasma sufentanil concentr...

Background The role of arteriovenous shunts such as dural fistulas, arterial steno?occlusive states, anatomic variants, and hypervascular tumors in the genesis pulsatile tinnitus (PT) has long been recognized. On venous side, diverticula, high?riding jugular bulb, sinus wall dehiscence have also implicated. However, overall most common cause—venous stenosis (VSS)—continues to be underrecognized...
