UNLABELLED Heart to mediastinum count ratio (H/M) has been commonly utilized as an indicator of myocardial I-123 MIBG uptake. However, normal ranges of H/M were markedly different among various gamma camera systems. The purpose of this study was to clarify whether scatter correction by two-window method standardizes H/M among various gamma camera systems. METHODS Scatter uncorrected and corre...

The key to utilizing muscle power for circulatory support lies with the development of a practical scheme by which contractile energy may be collected and efficiently delivered to the bloodstream. This work describes initial in vitro testing of a prototype muscle energy converter (MEC) designed to transform the power of in situ muscle contractions into hydraulic form. The MEC resembles a simple...

The stringent requirements of mobile edge computing (MEC) applications and functions fathom the high capacity dense deployment MEC hosts to upcoming wireless networks. However, operating such can significantly increase energy consumption. Thus, a base station (BS) unit act as self-powered BS. In this article, an effective dispatch mechanism for networks with capabilities is studied. First, two-...

Energy consumption has been a critical issue in high-performance computing systems, such as clusters and data centers. An existing technique to reduce energy consumption of applications is dynamic voltage/frequency scaling (DVFS). In this paper, we present a novel algorithm called EASLA for energy aware scheduling of precedence-constrained applications in the context of Service Level Agreement ...

With the rapid development of mobile computing, mobile-edge computing (MEC) has increasingly become an essential means to meet power requirements intelligent networked vehicles. However, users with high mobility and coupled dynamics are rarely considered in edge paradigms. In this article, we studied a UAV-assisted MEC system multiplatoon Our article aims maximize system’s weighted global energ...

An optimum sensor node placement mechanism for Wireless Sensor Network (WSN) is desirable in ensuring the location of sensor nodes that offers maximum coverage and connectivity with minimum energy consumption. This paper proposes a sensor node placement algorithm that utilizes a new biologically inspired optimization algorithm that imitates the behaviour of territorial predators in marking thei...

Direct current (DC) traction power systems are widely used in metro transport systems, with running rails usually being used as return conductors. When traction current flows through the running rails, a potential voltage known as “rail potential” is generated between the rails and ground. Currently, abnormal rises of rail potential exist in many railway lines during the operation of railway sy...

The Max Edge-Coloring (MEC) problem is a natural weighted generalization of the classical edgecoloring problem. Formally, in the MEC problem we are given a graph G = (V,E) with a weight function w : E → N , and we ask for a proper edge-coloring of G, M = {M1,M2, . . . ,Mk}, such that the sum of the weights of the heaviest edges in the color classes, W = ∑k i=1max{w(e)|e ∈ Mi}, is minimized. The...

Turbo codes have recently been considered for energy-constrained wireless communication applications, since they facilitate a low transmission energy consumption. However, in order to reduce the overall energy consumption, lookup table-log-BCJR (LUT-Log-BCJR) architectures having a low processing energy consumption are required. In this paper, we decompose the LUT-Log-BCJR architecture into its...

For economic benefit of wind power generation, the equivalent conversion relationships and models between the different “quality” energy are studied deeply in the conversion processes of wind energy. Considering the effect of load demand characteristics and energy supply price on the wind energy utilization mode comprehensively, the multi-objective trans-utilization optimization model of wind e...
