One of the concepts in restructuring the electric power industry is the ability to accurately and rapidly quantify the power transfer so-called as the available transfer capability (ATC). Accurate identification of ATC provides vital information for both planning and operation of the bulk power market in reserving transmission services. There are various methods used to determine ATC such as th...

c-reactive protein (crp) response was studied in 44 patients with acute angina pectoris admitted to the coronary care unit. 71 % of patients with acute myocardial infarction (mi)had positive crp test while 73% of patients presumed to have unstable angina pectoris had negative crp test. this test can be helpful in differentiating between acute mi and unstable angina pectoris.

Several proposed chaos based ciphers exploit the ergodic property of chaotic orbits. As chaotic systems are unstable and have sensitive dependence on initial conditions, the main difficulty for the receiver is to reproduce the chaotic signal that has been generated by the sender in order to correctly decrypt the message. This is performed by a self synchronizing device. In discrete cryptography...

we consider the semilinear elliptic boundary value problem  = ∈∂ω− δ = ∈ωu x xu x f u x x( ) 0;( ) λ ( ( ));where λ > 0 is a parameter, ω is a bounded region in rn with a smooth boundary, and f is asmooth function. we prove, under some additional conditions, the existence of a positive solution for λlarge. we prove that our solution u for λ large is such that = →∞∈ω|| u ||: sup| u(x) |xas λ ...

The establishment of irrevocable democracy, the rule of law, free market economic relations, and the protection of fundamental human rights have not yet assumed key significance in the South Caucasus countries. Consequently, all pressing problems of the region continue to intensify, keeping the region politically and economically unstable. Given contending geopolitical and geoeconomic interests...

Power grids are facing new challenges as a consequence of an increase in the use of renewable energy sources (RES). The fluctuation in power supply from these energy sources results in insecure and unstable operating points. Furthermore, the integration of distributed energy resources (DER), as well as distributed information systems, poses serious stability and security challenges in power net...

The progressive development of regions as open multi-level systems in the context aggravating contradictions between interests economic agents at stages deteriorating macroeconomic conditions and intensifying competition global national levels determine need to form an effective system security meso-level, taking into account numerous threats risk-forming factors. On one hand, digital transform...

introduction: unstable angina as a clinical condition includes a major group of patients manifested with acute coronary syndrome. misdiagnosis of this clinical syndrome causes myocardial infarction (mi) and death. conventional and advanced forms of treatment are used with the aim of rapid stabilization of unstable angina. although infusion of glucose - insulin - potassium (gik) solution has had...

This paper presents the use of Evolutionary Computation (EC) techniques, and more specifically the Genetic Programming (GP) technique, to Civil Engineering. This technique is applied here to a phenomenon that models the performance of structural concrete under controlled conditions throughout time. Several modifications were applied to the classic GP algorithm given the temporal nature of the c...

This paper proposes a private communication system with chaos using fixed-point digital computation. When fixed-point computation is adopted, chaotic properties of the modulated signal should be checked carefully as well as calculation error problems (especially, overflow problems). In this paper, we propose a novel chaos modem system for private communications including a chaotic neuron type n...
