‎in this work‎, ‎first the differential equation characterizing position vector‎ ‎of spacelike curve is obtained in lorentzian plane $mathbb{l}^{2}.$ then the‎ ‎special curves mentioned above are studied in lorentzian plane $mathbb{l}%‎‎^{2}.$ finally some characterizations of these special curves are given in‎ ‎$mathbb{l}^{2}.$‎

12. Considering discrete-time channels, sketch a chart showing the following plots: (a) Continuous-valued AWGN channel capacity (bits/symbol) as a function of SNR (b) Maximal conveyed information as a function of SNR for the following alphabets: 2-PSK, 4-PSK, 16-QAM, 64-QAM The characteristic shapes of the curves and asymptotic behaviors are essential. 13. The capacity per symbol for a continuo...

This paper presents a investigation on the performance of security under κ-μ shadowed fading channels using the Wyner’s classic wiretap model. A better fit was presented for the κ-μ shadowed fading channel curves in relation to other fading models, as Rayleigh and Nakagami-m. Results and analyses are obtained through the Secrecy Outage Probability, the Strictly Positive Secrecy Capacity and Ave...

This study examines the fragility curves of a bridge by two different analytical approaches; one utilizes the time-history analysis and the other uses the capacity spectrum method. The latter approach is one of the simplified nonlinear static procedures recently developed for buildings. In this respect, a sample of 10 nominally identical but statistically different bridges and 80 ground-motion ...

The probing response curves of an Internet path depict the first-order statistics of packet-train output signals (dispersion or rate) as a mathematical function of the input signal. Recent theoretical analysis showed that several useful path characteristics (e.g., raw capacity, crosstraffic rate, and residual bandwidth of the tight link) can be inferred from probing response curves [1]. To gain...

Heat capacity measurements were used to investigate the magnetic ordering processes in single-crystal samples of SrDy2O4 in a magnetic field applied along the [010] and [001] directions. In zero field this compound appears to be magnetically disordered down to at least 0.39 K. A magnetic field applied along the [010] direction induces a very sharp transition at 20 kOe, seen as a strong peak in ...

Batteries are one of the most important components in many mechatronics systems, as they supply power to the systems and their failures may lead to reduced performance or even catastrophic results. Therefore, the prediction analysis of remaining useful life (RUL) of batteries is very important. This paper develops a quantitative approach for battery RUL prediction using an adaptive bathtub-shap...

This paper investigates how r̄ms choose prices and production capacity when facing stochastic demand. With demand uncertainty, ̄rms face demand curves for their goods which implicitly subsume the selling mechanism adopted in the markets for these goods. The selling mechanisms considered in this analysis are bidding markets or auctions, and take-it-or-leave-it sales. They have di®erent implicatio...
