Per temporal frequency component, the (least squares) Parabo-lic Radon Transform (PRT) is equivalent to the (least squares) Nonuniform Discrete Fourier Transform (NDFT). This can be used in two ways. Firstly, the efficiency of the PRT can be improved by using very fast algorithms for the calculation of the direct nonuniform Fourier transform. Secondly, comparing the PRT to the NDFT provides use...

Petri nets are used to study many types of networked systems. [1] have designed a software tool for analysis and simulation of Petri nets. We extend this tool to handle a form of Petri net known as Predicate Transition (PrT) nets. We implement mechanisms that automate the process of folding a Petri net to a PrT net and finding invariants. We can compute invariants for systems that use either Pe...

We introduce a method based on precomputed radiance transfer (PRT) that allows interactive rendering of glossy surfaces and includes shadowing effects from dynamic, “all-frequency” lighting. Specifically, source lighting is represented by a cube map at resolution nL = 6× 32× 32. We present a novel PRT formulation which factors glossy BRDFs into purely view-dependent and light-dependent parts, a...

The extent to which different locomotor tasks require cognitive control is not well characterized. In this article, the authors consider the potential increase in attentional demands associated with carrying an anterior load while clearing an obstacle. Nine healthy male volunteers participated in 80 walking trials, 20 in each of 4 conditions: 1 no load condition (NL) and 3 carrying conditions (...

objective behavioral interventions such as relaxation training and biofeedback are some of the most effective interventions for management of migraine headaches. in this study we evaluated the utility of biofeedback-assisted progressive muscle relaxation training (prt) in the treatment of migraine. materials and methods in this prospective study, twenty patients (12-18 years old) with a confirm...

Objectives Patients with head and neck squamous cell carcinoma undergoing concomitant chemoradiotherapy (CCRT) frequently experience weight loss, especially loss of lean body mass (LBM), and reduced functional performance. This study investigated whether a 12-week hospital-based progressive resistance training (PRT) program during CCRT is feasible in the clinical setting before planning initiat...

The purpose of this study was to determine if taking part in a command-organized remedial physical condition program based on the OPNAVINST 6110.1 Basic Exercise Program (BEP) is effective in reducing body fat, improving failure-specific performance on components of the Physical Readiness Test (PRT), and improving overall physical fitness level. Pre- and post-program PRT results collected for p...

본 논문은 직교 주파수 분할 다중 반송파 (OFDM; orthogonal frequency division modulation) 시스템의 최대 전력 대 평균 전력 비율 (PAPR; peak to average-power ratio)을 감소하기 위한 톤 예약 기법 (TR; tone reservation)에서 최고 줄임 톤 (PRT; peak reduction tone) 집합을 적응적으로 적용하는 새로운 방법을 제안한다. TR 기법은 PRT 집합의 크기가 커질수록 PAPR 감소성능이 뛰어난 역관계가 존재한다. OFDM신호의 PAPR을 감소시키기 위해서는 높은 톤 비율을 적용해서 많은 톤을 PRT로 선택해서 PAPR을 감소시키면 데이터 전송효율이 떨어진다. 본 논문은 크기가 서로 다른 PRT 집합을 미리 선...

BACKGROUND The aim of this systematic review was to quantify the effectiveness of progressive resistance strength training (PRT) to reduce physical disability in older people. METHODS Randomized controlled trials were identified from searches of relevant databases and study reference lists and contacts with researchers. Two reviewers independently screened the trials for eligibility, rated th...
