The efficient and reliable handling of numerous communicating devices responsible for the monitoring and control of the distribution grid constitutes one of the key challenges for the realization of the smart grid. Cellular technology relying on LTE-based standards has been identified as a promising option to support advanced distribution-grid operations with stringent communication requirements....
We motivate DARTS, a new technique for workload sampling to drive architectural simulation, that carefully integrates hardware performance counter monitoring with fast, dynamic binary translation. This paper focuses on a key finding that motivates the DARTS methodology. We present our experience applying it to the generation of simulation points for the integer benchmarks of the SPEC CPU2006 suite...
Mobile cloud computing (MCC) has emerged as a solution to overcome the resource constraints of mobile devices by using computation offloading to execute mobile application tasks on remote servers, thus enhancing performance and reducing the energy consumption of mobile devices. Nevertheless, the effectiveness of an offloading solution is determined by its ability to infer when offloading will improve...
Minimum performance specifications and testing methods for the evaluation of radiation portal monitors, also known as RPMs, are contained in this standard. These monitors are large-size permanently mounted-type instruments. These instruments are primarily designed for the detection of radioactive materials emitting gamma rays and neutrons. The specifications for general, radiological, environmental,...
Network monitoring system plays an important role in ensuring network security and maintaining network stability. Based on the thorough study of the application of the simple network management protocol (SNMP), a network intelligent monitoring model for test internet protocol (IP) network is designed, and a network monitoring system is developed. The system can realize the network equipment operation...
The distributed shared memory (DSM)-based computation offloading scheme allows collaborative multiple threads to dynamically migrate and execute across a mobile device and computing nodes. Despite this strong advantage, it misses a significant portion of the potential performance gain because the traditional DSM model is suboptimal for computation offloading. This paper proposes an enhanced DSM model...
One of the main challenges for wireless body area networks (WBANs) is to evaluate realistic methods to generate channel models for new different purposes and various environments quickly and flexibly. Finite integration technique (FIT) has shown to be promising method for modeling channels characteristics in WBAN deployment scenarios. Applying simulation based channel modeling on the performance evaluations...
Established in this standard are criteria for variable selection, performance, design,and qualification of accident monitoring instrumentation for anticipated operational, design basisevents and severe accidents.
Data collected by fitness trackers could play an important role in improving the health and well-being of the individuals who wear them. Many insurance companies even offer monetary rewards to participants who meet certain steps or calorie goals. However, in order for it to be useful, the collected data must be accurate and also reflect real-world performance. While previous studies have compared...
This paper is concerned to design of direct coupled solar water pumping system without using batteries. Technical, economic and environmental parameters are considered in the design procedures. Performance evaluation of solar water pumping system is studied using three expressions; yield factor (YF), wire to water energy efficiency (WWEE) and system performance index (SPI). A full monitoring system...
System Protection Schemes (SPS) are considered as an effective tool for enhancing the resilience of the power system towards rare contingencies. The validation of SPS is difficult by using conventional SCADA data due to its inherent low scan rate and skewedness. Under such condition, Synchrophasors has been found to be better suited for performance evaluation SPS and review of its design. This paper...
Driven by rapid growth in wireless demand, spectrum sharing has recently been the focus of extensive research. A common concern is how to address coexistence-related interference, especially when the involved systems operate under different protocols. In this paper, we outline a framework for exploiting full-duplex (FD) capabilities to support coexistence in a heterogeneous spectrum sharing environment...
WiFi-enabled devices broadcast a vast amount of data without being associated to any access points. To study and analyze this data, a generic passive WiFi tracking system called Probr was developed. Probr manages various types of WiFi capturing devices, collects captured WiFi traces, processes collected WiFi traces, and visualizes WiFi activities via its Web interface. Probr supports several on-line...
As communication is the most fundamental resource for a smart city, it cannot allow any disruption with the related services. Therefore, real-time monitoring systems for the QoS state for the communication infrastructure are vital. Such systems that can detect communications failure can be used also for redeploying emergency and ad-hoc communications infrastructures. Sudden-Onset Disasters (SOD) typically...
This paper explains the design and implementation of a low cost Non-Intrusive Load Monitoring (NILM) system. The system is designed using open source hardware and off-the-shelf components for a cost of below 8 USD. The device identification system makes use of the current-peak signature to uniquely identify devices turned ON at any instance in time. A current sensor is used at the utility service...
Performance and compliance objectives have become crucial for critical sites. Balancing security, energy and costs with operational objectives is the current main challenge for critical site administrators. While current systems are not integrated enough to provide an overall view of the site performances on such targets, the FUSE-IT project intend to propose a new paradigm: the convergence of monitoring...
Based on the technical improvement of the High Frequency Partial Discharge Measurement applied to the insulation diagnosis of Extra-High-Voltage power cable system since last two decades in the world-wide market, the first model for Partial Discharge Monitoring System was also developed in Korea and then it was applied to KEPCO underground power cable system several years ago. However, it has brought...
In this work, a set of test structures that meets the emerging need for Micro-Electro-Mechanical Systems (MEMS) integration process monitoring and material/device property measurement at the wafer level is presented. The CMOS-MEMS test structures are designed to evaluate and assist the development of an integrated CMOS-MEMS process. The acquired data from the test structures will be useful for identifying...
Ultra-high-frequency (UHF) partial discharge detection has become a most important tool for condition maintenance of gas insulated substations (GIS).
