Objective The study aims to identify the optimal 4Kscore thresholds determine need for a prostate biopsy when multiparametric magnetic resonance imaging (MRI) (mpMRI) is negative or indeterminate. Materials and methods We analysed retrospective data from men in eight different institutions who underwent an mpMRI, evaluation of cancer. selected with (PIRADS ≤2) indeterminate 3) mpMRI. values wer...

A Dynamic Programming formulation is used to obtain an optimal strategy for the handoff problem in cellular radio systems. The formulation includes the modeling of the underlying randomness in received signal strengths and of the mobile’s movements. The cost function is designed such that there is a cost associated with switching and a reward for improving the quality of the call. The optimum d...

We study the effects of random nonlocal connections on networks of chaotic maps under threshold activated coupling. In threshold regimes where a large number of unsynchronized attractors occur under regular connections, we show how nonlocal rewirings yield synchronized networks. However, the dependence of the synchronized fraction on the fraction of randomized nonlocal links is typically nonmon...

At present threshold values are based on the mean and standard deviation of link utilisation are used as trigger to find more stable route in the network. The Aim of this paper is to use a technique based on the wavelet method (of Abry and Veitch 1998 ) to detect a real time change in the characteristics of self-similar traffic and this can be used as a threshold trigger to provide optimum path...

−− This paper presents a new Fuzzy Dynamic Programming model that calculates the optimum solution of problems with uncertainties in data defined by fuzzy sets. The result includes the determination of an Intrinsic Risk Threshold of the solution. Extrinsic Risk Thresholds may also be set by a Decision Maker, in order to obtain more robust solutions. The technique is applied to the calculation of...

For a FHIBFSK system, a new type of combiner termed the product combining receiver (PCR) is investigated. The performance of the PCR is evaluated for the cases of on/off partial band noise with optimum jamming fraction, and worst case partial band tone jamming. The performance of PCR is shown to be comparable to that of the clipper receiver. The effect of diversity combining along with convolut...

An effective approach for extracting document images from a As an example, Otsu’s celebrated paper [8] chooses the optinoisy background is introduced. The entire scheme is divided into three submum threshold by maximizing the between-class variance with stechniques – the initial preprocessing operations for noise cluster tightening, an exhaustive search, while, Kittler and Illingworth’s work [5...

Erbium-doped Y203 integrated optical amplifiers are designed for low-threshold operation and 3dB amplification. The most important design parameter for minimal threshold, the erbium concentration, is found to have an optimum value of 0.35 at% for a given waveguide structure with 1.0dBcm -1 background loss. The corresponding threshold power is 7 mW. The pump power to obtain 3dB gain is found to ...

Electric pulp testing is one of the pulp vitality tests which aid dentists in diagnosis of the pulp status. This test is technique sensitive and hence may elicit false responses. There are some concerns regarding the optimal placement of the probe tip. The threshold value (the lowest electric current at which sensation is perceived) is reached when an adequate number of nerve fibers are stimula...
