A P2P computing environment can be an ideal platform for resource-sharing services in an organisation if it provides trust mechanisms. Current P2P technologies offer content-sharing services for non-sensitive public domains in the absence of trust mechanisms. The lack of sophisticated trust mechanisms in the current P2P environment has become a serious constraint for broader applications of the...

Reactive power planning (RPP), or Var planning, is to identify the optimal size and location of reactive power sources. In this paper, first, the previous work using least square method to simplify the voltage stability constrained OPF (VSCOPF) model for RPP is presented. Then, this paper presents a new model simplification solution using interpolation. The interpolation approach can be easily ...

The Rural Postman Problem (RPP) is a particular Arc Routing Problem (ARP) which consists of determining a minimum cost circuit on a graph so that a given subset of required edges is traversed. The RPP is an NP-hard problem with significant real-life applications. This paper introduces an original approach based on Memetic Algorithms the MARP algorithm to solve the RPP and, also deals with an in...

Abstract – Resonant parametric perturbation (RPP) method is an effective non-feedback method for controlling chaos. In this paper, the above method is applied for the current programmed buck-boost dc-dc converter which exhibits chaotic for wide parameter variations. The different possible operating regimes leading to chaotic operation of the current mode controlled buck-boost converter is discu...

The reeectivity due to stimulated Brillouin backscattering (SBS) from an ensemble of independent laser speckles is investigated for diierent speckle statistics. Calculations are based on numerical simulations with a multidi-mensional code and a compact model describing the main features of speckle self-focusing. In particular, the simulations and the model are applied to speckle ensembles due t...

Heart rate, Blood Pressure and Rate pressure product are important physiological parameters that can be utilized to analyze the physical condition of the human body. However, the step-by-step analysis on the changes of ECG waveforms and RPP before and after regular exercise has been presenting in this paper. This proposed work examines the Changes of ECG waveforms after regular exercise. Rate p...

Renal perfusion pressure (RPP) regulates renin release with a reduction of RPP stimulating and an elevation inhibiting renin secretion. The precise sensing and effector mechanisms by which changes in arterial pressure are linked to the exocytosis of renin are not well-defined. The present experiments were designed to study the potential role of adenosine as a mediator of this renal baroreceptor...

In 26 patients having coronary grafts, haemodynamics, coronary sinus blood flow and the arterio-coronary sinus difference of oxygen content were determined, awake and at four intervals during morphine-oxygen or halothane--oxygen anaesthesia. Rate-pressure product (RPP), triple product (TP) and myocardial oxygen consumption (MVO2) were calculated. The correlation of the two indirect indices to M...

This study tests the hypothesis that P2X1 receptors mediate pressure-induced afferent arteriolar autoregulatory responses. Afferent arterioles from rats and P2X1 KO mice were examined using the juxtamedullary nephron technique. Arteriolar diameter was measured in response to step increases in renal perfusion pressure (RPP). Autoregulatory adjustments in diameter were measured before and during ...

PURPOSE Evaluate the results of urinary continence on patients who had undergone radical perineal prostatectomy (RPP) for clinically localized prostate cancer. MATERIALS AND METHODS We analyzed the continence data of 120 patients with pathology of cT1-cT2N0M0 prostate cancer and who had undergone RPP. Continence was assessed on the day of catheter removal, at the end of the first and third mo...
