Decision making tasks are often complex and ill-defined, and they are also multi-aspect because many factors influence the decision process. Decision support systems (DSS) which are frequently used in business and manufacturing have a potential to cope with vagueness and illstructure of complex decision making situations. Also an optimum DSS can be developed for multidimensional decision proble...

Decision Support Systems (DSSs) are utilized to support a users decision process. One generally required characteristic of a DSS is that it be an interactive system. Generally the degree of interaction between the human and the system is such that one can view the information processing activity as being performed by the human-computer information processor. Although DSSs are fairly commonly us...

Nowadays, managers in organizations usually have to confront increasingly complicated decision environments and dynamically changed decision demands. Traditional Decision Support Systems (DSSs) sometimes neglect that both requirements and objectives of decisions are indeterminate, and thus do not support flexible decision making. In order to meet dynamically changed contexts, DSS generators are...

Numerical simulations on the evolution of stepscrew and edge-screw optical phase dislocations in bulk saturable self-defocusing nonlinear media are presented, with emphasis on their ability to induce steering waveguides for signal beams (pulses). Two schemes for directional coupling of such signals, both ensuring a reasonable coupling-to-crosstalk efficiency ratio, are investigated. The paramet...

Abstract Duplex stainless steels (DSSs), which consist of ferrite and austenite phases, are widely used owing to their high strength good corrosion resistance. However, the oxidation behavior DSSs is extremely complicated because they have dual phases. In this study, changes in scale metal substrate during were investigated. UNS S32101 (Fe-21.5%Cr–5%Mn–1.5%Ni–0.3%Mo–0.22%N), a typical type DSS,...

Cohesive Distributed Satellite Systems (CDSSs) is a key enabling technology for the future of remote sensing and communication missions. However, they have to meet strict synchronization requirements before their use generalized. When clock or local oscillator signals are generated locally at each distributed nodes, achieving exact in absolute phase, frequency, time complex problem. In addition...

Despite the fact ultra-wideband technology has been around for over 30 years, there is a newfound excitement about its potential for communications. In this paper we are specifically focused on a software radio transceiver design for impulse-based UWB with the ability to transmit a raw data rate of 100 Mbps yet encompass the adaptability of a reconfigurable digital receiver. Direct sequence spr...

Many-core systems are susceptible to attacks launched by thermal covert channel (TCC) attacks. Detection of TCC often relies on the use threshold-based approaches or variants, and a countermeasure thwart can be applied only after an attack is deemed present. In this article, we describe direct sequence spread spectrum (DSSS)-based TCC, where its data modulated pseudo-random bit sequence. Unfort...
