We study the inverse scattering problem of determining a magnetic field and electric potential from measurements corresponding to finitely many plane waves. The main result shows that coefficients are uniquely determined by $2n$ up natural gauge. also show one can recover full first order term for related equation having no gauge invariance, it is possible reduce number if have certain symmetri...
در این پایان نامه، با فرض اینکه v یک *c - مدول هیلبرت تولید شده ی شمارا روی یک $ c^{ast} $,ـ جبر $ a $ است، ثابت خواهیم کرد که دنباله ی $ lbrace f_{i}:iin i brace subseteq v $ یک قاب استاندارد برای $ v $ است اگر و تنها اگر سری $ sum_{iin i} langle x,f_{i} angle langle f_{i},x angle $ برای هر $ xin v $ همگرا (در نرم) باشد و ثابت های $d>0$ و $c $ موجود ب...
The solar arrays are one of the most promising renewable energy technologies for providing energy needs . in buildings. For installed solar panels on building roofs, knowing the optimal inclination angle is important in order to obtain the maximum annual or seasonal energy. In fact, the changes in slope angle affect the amount of solar radiation that reaches the surface of the panel. In this s...
purpose : to describe a distinctive pattern of induced higher order aberration (hoa) after lasik for mixed astigmatism case reports : wavefront-guided lasik with iris recognition and eye tracking (excimer laser: technolas 217z apt protocol microkeratome: moria cb) was performed in six eyes with moderate to high mixed astigmatism for a nominal optical zone of 6.3 mm. the patients were re-examine...
the cracked brazilian disc (cbd) specimen is widely used in order to determine mode-i/ii and mixed-mode fracture toughness of a rock medium. in this study, the stress intensity factor (sif) on the crack-tip in this specimen is calculated for various geometrical crack conditions using the extended-finite element method (x-fem). this method is based upon the finite element method (fem). in this m...
The elevation angle θ is relevant for the Low Earth orbit (LEO) satellite communications since it always changing its relative position with respect to fixed stations (ES’s), and this affects link length received power, PR. This article provides a new methodology compute probability density function (PDF) cumulative distribution (CDF) of angle, θ, diverse ES locations. requires as input paramet...
Abstract Using the combinatorics of underlying simplicial complex K , we give various upper and lower bounds for Lusternik–Schnirelmann (LS) category moment-angle complexes
