Distribution system analysis with high penetrations of distributed energy resources (DER) requires quasi-static time-series (QSTS) analysis to capture the time-varying and time-dependent aspects of the system, but current QSTS algorithms are prohibitively burdensome and computationally intensive. This paper proposes a novel deviation-based algorithm to calculate the critical time periods when QSTS...
Classification of electrical loads presents multiple benefits. From the ability to inform customer how their appliances contribute to the overall electricity cost, to allowing electric companies and virtual aggregators to institute demand response mechanisms. In this paper we propose a new type of active sensing method which breaks down real-time data into fixed segments which can be quickly analyzed...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
DFA Technology, developed by Texas A&M Engineering in collaboration with EPRI and the utility industry, provides operational visibility and awareness of distribution circuit events, based upon real-time, autonomous monitoring of substation-based CTs and PTs. DFA monitoring devices monitor current and voltage waveforms continuously, detect anomalies, infer circuit events that likely caused those...
In this paper, we formed prediction intervals using historical similarities, found through the direct correlation. At first, a string of 5 to 20 recent samples is correlated with a long training string of samples. Then, the highest normalized correlation values and corresponding indexes are picked. After that, the amplitudes of the matched samples are adjusted by multiplying the value with the amplitude...
This study presents the effect of supplying electrical ways in power electrical distribution system (PDS) to reliability indexes by alternating closed breakers in the water production plant. PDS in Mahasawat water treatment plant (MHS) is proposed as a case study. PowerFactory DIgSILENT program is used and simulated to find the result of alternative breakers to be closed or opened through Customer...
The performance of a low-complexity detection technique for OFDM-IM over the Nakagami-m fading channel has been analyzed. The orthogonal frequency-division multiplexing with index modulation (OFDM-IM) has recently been used in conjunction with the subcarriers using on-off keying modulation. The result shows improved performance in comparison with the conventional OFDM. The closed-form expression for...
The paper presents the researches to determine the effectiveness of different criteria to estimate the complex biology objects clustering quality. The gene expression sequences of cancer patients were used as experimental data. The degree of the studied objects similarity was estimated by the comparison of the gene expression sequences profile using different metrics to estimate the objects proximity...
In this paper, we study the problem of set containment join. Given two collections R and S of records, the set containment join R./S retrieves all record pairs f(r, s)g 2 R S such that r s. This problem has been extensively studied in the literature and has many important applications in commercial and scientific fields. Recent research focuses on the in-memory set containment join algorithms, and...
Social networks have become a vital mechanism to disseminate information to friends and colleagues. But the dynamic nature of information and user connectivity within these networks raised many new and challenging research problems. One of them is the query-related topic search in social networks. In this work, we investigate the important problem of the personalized influential topic search. There...
A record is a particular structure that composes a reference to your information that makes it less demanding to gaze upward. In Postgres it is a duplicate of the thing you wish to file joined with a reference to the genuine information area. While getting to information, Postgres will either utilize some type of a file on the off chance that it exists or a successive output. A successive sweep is...
Noise estimation plays an essential role in enhancing the performance of non-coherent spectrum sensors such as energy detectors. If the noise energy is misestimated, detector performance may deteriorate. In this paper, we present an energy detector based on the behavior that Empirical Mode Decomposition (EMD) has on noise-only channels. EMD decomposes time-series signals into a finite set of components...
Sensor network virtualization enables the possibility of sharing common physical resources to multiple stakeholder applications. This paper focuses on addressing the dynamic adaptation of already assigned virtual sensor network resources to respond to time varying application demands. We propose an optimization framework that dynamically allocate applications into sensor nodes while accounting for...
Empowered by the orthogonal frequency division multiplexing (OFDM) technology, elastic optical networks (EONs) have emerged as a promising solution for future high-speed networks. Routing and spectrum allocation (RSA) is one of the key challenges to the design of EONs. An adaptive RSA is required to meet the robustness objective of EONs. The relative cost concept can be used to implement an adaptive...
As technology becomes a larger part of everyday life, it becomes increasingly more important for CS and CIT students to learn about cyber security during their education. While many cyber security oriented courses exist, it is also necessary that students must be able to work and learn in an environment that resembles a real world context. To address this problem it has become common to adapt cyber...
Robust semidefinite programs are NP-hard in general. In contrast, robust linear programs admit equivalent reformulations as finite-dimensional convex programs provided that the problem data are parameterized affinely in the uncertain parameters; and that the underlying uncertainty set is described by an affine slice of a proper cone. In this paper, we propose a hierarchy of inner and outer polyhedral...
This paper focuses on the production scheduling problem in a rotor workshop. The scheduling problem is formulated as a reentrant hybrid flow shop problem with non-identical machines in parallel. Some heuristics are developed to solve the problem. The proposed algorithms are compared through various instances that are generated based on real operations in the workshop. Experimental result also reveals...
During recent years, Peer-to-Peer (P2P) Content Sharing Networks (CSNs) have intrigued researchers to measure and analyze them for the dominant proportion of P2P traffic volume and wide applications of the sharing platform. However, to the best of our knowledge, most of the measurement tools have not been updated under the current situations of P2P CSNs. In this paper, we develop an enhanced measurement...
