In cognitive radio networks (CRNs), spectrum sensing data falsification (SSDF) is one of the most typical attack which hugely degrades the detection performance of cooperative spectrum sensing (CSS). SSDF and defense strategies have been an active field of research, but countermeasures of existing researches are sensitive to the number of malicious users (MUs). In this paper, we propose a two-stage...
Day-Ahead Unit Commitment is a typical business process of regional transmission organizations (RTO) and some vertically integrated utilities to ensure enough generation capacity is committed day-ahead to meet the load for the next day. In many cases, transmission constraints are required to be taken into consideration under the framework of security-constrained unit commitment (SCUC). Transmission...
Incorporating line switching as a part of security enhancement could more effectively alleviate overloads of branch equipment in system operations. In market operations, co-optimizing transmission topology and generation dispatch could be a viable way to improve economic efficiency. This paper discusses the integration of line switching in energy and market management systems (EMS/MMS) for control...
In this paper, we derive application-level reliability metrics of various safety applications with worst-case settings and vehicular environments based on an accurate analytical model in one dimension vehicular communication networks. The reliability related QoS metrics in both the MAC-level and the Application-level including packet reception ratio, T-window reliability, and awareness probability...
Under Midwest ISO's real-time market, energy and ancillary service products are co-optimized. It is very important for operators to have an indication of where the system stands and take proper action if needed. In this paper, both analytic and numerical methods are presented to evaluate the available room to meet power balance and reserve requirements. It essentially presents indexes on how far away...
Due to the applications of high technology, a catastrophic failure of Computerized numerical control (CNC) machine tool rarely happens at normal operation conditions. Traditional reliability assessment methods based on time-to-failure distributions have the difficulty to estimate the reliability precisely. This paper presents a novel reliability assessment methodology that estimates the reliability...
Knowledge sharing, the key point in knowledge management, becomes an important research issue gradually because of its great influence on the competitive power of enterprises. So, based on the review of the relevant researches in the field of knowledge sharing and marketing channels, this research analyzed the relationship between knowledge sharing and commitment, developed a theoretical model, and...
To conceptualize the indirect causal impact of IT capability on organizational performance, this paper first posits that managerial IT capabilities and technical IT capabilities are the dimensions of IT capability construct. Then, using structural equation modeling with data collected from IT and business executives in 250 firms, we empirically validate the conceptual relationship model between IT...
