Most of the industrial control loops are multivariable control loops, so the control system performance evaluation is the major study of multivariable control system. The combustion control system of power unit is a typical multivariable control system, which is used to guarantee the economy and safety of the boiler. This paper presents a kind of performance evaluation method based on data-driven...
Due to network dynamics, performance tuning is often indispensable in network management. In this paper, we propose MOE, a framework integrating network performance monitoring, optimization and evaluation. This is a trial towards the top-down and systematic management of network performance. We validate MOE based on a typical scenario in the real network environment. Results show that MOE can collect...
A key challenge for Machine to Machine (M2M) communication over the Long term Evolution-Advanced (LTE-A) is the performance of Random Access Channel (RACH) in interference-limited scenarios. This paper presents results of a Radio Access Network (RAN) evaluated for the macro-cell where the interference from M2M devices (M2M-Ds) is considered. The paper shows that considering an interference free scenario...
Because of its high IO performance, Solid State Drives (SSDs) are playing an important role in cloud storage services. However, its ten times price of Hard Disk Drives (HDDs) makes it unaffordable for most companies to replace all traditional HDD storage with high performance SSD storage. Hybrid storage becomes a trade-off solution between relatively high performance and acceptable cost. In this paper,...
Wireless Sensor Network (WSN) comprises of many distributed independent tiny sensors that used to monitor statistical data of specific environmental conditions such as temperature, humidity, rain, pressure and many other. WSN use unlicensed 2.4 GHz Industrial, Scientific and Medical (ISM) radio frequency band for data transmission. WSN applications are being used in many industries and civilian areas,...
Driver fatigue problem is one of the important factors of traffic accidents. Recent years, many research had investigated that using EEG signals can effectively detect driver's drowsiness level. However, real-time monitoring system is required to apply these fatigue level detection techniques in the practical application, especially in the real-road driving. Therefore, it required less channels, portable...
Based on Complete and Incomplete Contract Theory, the paper analyzes the root causes of different kinds of problems during the process of budget compilation and implementation of university research funds. These problems include false budget, fiddling on expenditure, and hard to monitor and control. Based on these analyses, the paper also provides corresponding strategy. The analysis in the paper...
Metal matrix composites (MMCs) composed of Ag and single-wall carbon nanotubes (SWCNTs) have been developed as an electrode material for inverted metamorphic multi-junction (IMM) solar cells. Scanning electron microscopy analysis reveals that these Ag-SWCNT MMCs may alleviate issues caused by fracture of the fragile IMMs, and that the metal grain structure varies based on the thickness (or weight...
Certification is the process in which a manufacturer has to prove to authorities that an aircraft and systems like safety-critical avionic systems work safely as intended without unacceptable hazards. Means to achieve this are redundancy, separation/protection, monitoring, and recovery mechanisms. The objective of this paper is to provide a cost-efficient solution for monitoring of Commercial Off-The-Shelf...
An analytical method for calculating the energy production by a linear solar PV/T concentrator has been presented. The solar module under test is a linear solar concentrator that can provide both electrical and thermal energy. Due to the rotation of the collector during the sun tracking, each collector shades the subsequent collector. This situation decreases the energy production of the solar module...
Analytics of network telemetry data helps address many important operational problems. Traditional Big Data approaches run into limitations even as they push scale boundaries for processing data further. One reason for this is the fact that in many cases, the bottleneck for analytics is not analytics processing itself but the generation and export of the data on which analytics depends. The amount...
From the comparison of the data available in the field literature, it follows that the range of oscillometric ratios is quite extensive, with an interval of 20% for systolic and around 30% for diastolic blood pressure. For example Geddes [8] states that these may range from 0.45 to 0.57 for systolic and from 0.75 to 0.86 for diastolic. Current commercial devices were not designed to perform the task...
With continuous development of the visual presentation technology on stage, special effect devices have occupied an important place already. In contrast to traditional mutually independent control method, we propose and realize, in this paper, an integrated-control system of stage effect devices. This system ultimately achieve the effect of unified and cooperative control. In addition, we also further...
In order to meet the requirement of cultural performance on stage design, people always make a comprehensive plan for the character or some specific scene according to the proceeding of the story line. Therefore, we should make full use of various kinds of visual elements such as stage lighting and special effect devices. In this paper, the current control method for different kinds of visual effect...
This stage manage system is designed specifically for the integrated-control console of visual-effect equipment. System architecture, functional implementation and technical solution are proposed detailedly in this paper. This system is established based on C/S framework. Data transmission between the stage management console of visual-effect equipment and the integrated-control system is implemented...

Power grids are responsible for the transmission and distribution of electricity to end-users. These systems are undergoing a modernization process through the use of Information and Communication Technology (ICT), transforming the electric system into Smart Grids. In this context, Supervisory Control and Data Acquisition (SCADA) systems are responsible for the management and monitoring of substations...
The need for the development and use of a Network Management System (NMS) arises ipso facto that a typically huge network incorporates a huge number of interlinked network components for the transfer of data across channels making it essential to ensure the up keeping of such components for an uninterrupted communication. Such large scale deployment of components makes it tricky for an individual...
The paper proposes a new type of sensor for heart rhythm monitoring. It is less uncomfortable than classic ECG monitors and provides almost real-time information to the medical team, which is useful in monitoring patients with chronic heart conditions. It also can prove useful in cases when the patient suffers from skin conditions by minimizing contact surface, by utilizing the capabilities of modern...
In this paper we present our approach to create an end-to-end software platform to enable the creation of meaningful and systematic, cross-dataset performance evaluations and benchmarks of Non-Intrusive Load Monitoring technology. We specifically propose a new file format to represent public datasets, a software framework to implement algorithms and metrics as well as the application of ceiling analysis...
