In the last lecture, we discussed a recursive construction of a pseudorandom generator that is based on expanders: the INW generator. In this lecture we will show that the INW-generator with a suitable instantiation of an expander family produces pseudorandomness for machines that run in logarithmic space. We also introduce Nisan’s generator, which is a pseudorandom generator that has a recursi...

This article presents an information retrieval system (IRS) using genetic algorithm to increase the performance and efficiency of Text to Matrix Generator (TMG).This paper presents an extension in previous work of Text to Matrix Generator (TMG). In this paper, we proposed a genetic algorithm approach in Text to Matrix Generator for information retrieval. This experimental result shows an improv...

Besides achieving an optimal scheduling generator, the operation safety of generator itself needs to be focused on. The development virtual visualization a capability curve simulation visualize condition is proposed in this paper. In paper, neural network applied redraw original generator’s curve. can simulate operating considering limitation constraints on various elements generator. Furthermo...

It is a longstanding open problem to devise an oracle relative to which BQP does not lie in the Polynomial-Time Hierarchy (PH). We advance a natural conjecture about the capacity of the NisanWigderson pseudorandom generator [NW94] to fool AC0, with MAJORITY as its hard function. Our conjecture is essentially that the loss due to the hybrid argument (which is a component of the standard proof fr...

Rotations of the line of sight are mainly implemented by coordinated motion of the eyes and head. Here, we propose a model for the kinematics of three-dimensional (3-D) head-unrestrained gaze-shifts. The model was designed to account for major principles in the known behavior, such as gaze accuracy, spatiotemporal coordination of saccades with vestibulo-ocular reflex (VOR), relative eye and hea...

background: local ablative treatments play an important role for patients who cannot be treated surgically. radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. microwave ablation (mwa) is a new minimally invasive treatment promising several improvements. the aim of this retrospective study was to evaluate the eff...

a 76-yr-old man with unipolar ventricular pacemaker, previously implanted in the right ventricular apex, presented with syncopal attack and twitching of the right pectoralis muscle. he finally was diagnosed as having twiddler's syndrome. the patient had a pulse rate of 36/min and cannon waves in the neck veins. chest radiography showed a dislodged pacing lead completely wrapped around the pulse...
