CIFER software is used to identify steering and roll dynamics of a container ship. In this software, advanced features such as the Chirp-Z transform(CZt) and composite window opt.m.zation are applied to the t.m. history of steering and roll dynamics to extract high quality frequency responses. From the extracted frequency responses, two linear transfer functions of Nomoto model are fitted for yaw and roll dynamics of the vessel. Based on the identified Nomoto model, a PID heading controller and a Kalman filter observer are constructed. the simulation results of heading controller for line of sight(LOS) waypoint guidance show excellent tracking of pilot inputs in the presence of wave induced motions and forces.

Chalcogenide films find many applications in electronics as memory device, laser writer & xerography. to tailor the property to the requirement, various compositions of Cd, te and Se have been deposited and characterized optically. Films have been deposited by thermal evaporation as well as by electron beam evaporation. thermal analysis such as tGA, DtA and DSC has been carried out before deposition to ensure the composition. Dependence of Eg on the composition has been justified from (t% data) transmittance measurements. Drastic changes in optical property due to annealing in the range 200°C to 400°C have been investigated.

the evolutionary algorit.m. a subset of computational intelligence techniques, is a generic population-based stochastic opt.m.zation algorit.m.which uses a mechanism motivated by biological concepts. Bio-inspired computing can implement successful opt.m.zation methods and adaptation approaches, which are inspired by the natural evolution and collective behavior observed in species, respectively. Although all the meta-heuristic algorit.m. have different inspirational sources, their objective is to find the opt.m.m(minimum or maximum), which is problem-specific. We propose and evaluate a novel synergistic fibroblast opt.m.zation(SFO) algorit.m. which exhibits the behavior of a fibroblast cellular organism in the dermal wound-healing process. Various characteristics of benchmark suites are applied to validate the robustness, reliability, generalization, and comprehensibility of SFO in diverse and complex situations. the encouraging results suggest that the collaborative and self-adaptive behaviors of fibroblasts have intellectually found the opt.m.m solution with several different features that can improve the effectiveness of opt.m.zation strategies for solving non-linear complicated problems.

Herein, we present an approach to look for the best phenomenon to measure quant.m.correlation. the syst.m.of two isolated qubits each interacting with a single-mode cavity was theoretically created to study the quant.m.correlation. Some of the phenomena, such as the quant.m.discord and concurrence, were generated through such a syst.m. the influences of initial state purity, qubit.m.tion, and detuning parameters were discussed for the phenomena. these parameters for a specific value show that the behavior of phenomena are analogous. It is interesting to mention that some values of detuning undergo a sudden death of phenomena, and the quant.m.discord still captures the qubits quant.m.correlation. We predict that the quant.m.discord may be a better measure of quant.m.correlation than concurrence.

the mobility of clusters on a semiconductor surface for various values of cluster size is studied as a function of t.m.erature by kinetic monte Carlo method. the cluster resides on the surface of a square grid. Kinetic processes such as the diffusion of single particles on the surface, their attachment and detachment to/from clusters, diffusion of particles along cluster edges are considered. the clusters considered in this study consist of 150-6000 at.m. per cluster on average. A statistical probability of motion to each direction is assigned to each particle where a particle with four nearest neighbors is assumed to be immobile. the mobility of a cluster is found from the root.m.an square displacement of the center of mass of the cluster as a function of t.m.. It is found that the diffusion coefficient of clusters goes as D = A（t）Na where N is the average number of particles in the cluster, A（t） is a t.m.erature-dependent constant and a is a parameter with a value of about -0.64 〈 a 〈 -0.75. the value of a is found to be independent of cluster sizes and t.m.erature values （170-220 K） considered in this study. As the diffusion along the perimeter of the cluster becomes prohibitive, the exponent approaches a value of -0.5. the diffusion coefficient is found to change by one order of magnitude as a function of cluster size.

Seismic waves from a magnitude 8.3 earthquake in Japan were consistently recorded by five nearly identical gPhone gravity meters in Colorado. Good correlation was also found in the response of two different types of gravity meters and a standard seismometer in Walferdange, Luxembourg to an earthquake of magnitude 8.2 in Japan, indicating that all of them were capable of measuring the surface waves reliably. the gravity meters, however, recorded 11 separate arrivals of Raleigh waves, while the seismometer only one. thus the gravity meters may be useful for obtaining new information in the study of seismic velocities, attenuation and dispersion.

研究了西藏泽当地区冈底斯逆冲断层（ＧＴ）和念青唐古拉山峰东侧两条山谷（ＮＴ）中８个钾长石样品的ＭＤＤ冷却历史，对钾长石低温阶段异常高年龄进行了Ｃ１校正，得到了两次明显的快速冷却事件。前者（ＧＴ）提供了网底斯逆冲断层的活动时间２７～２４Ｍａ、下限年龄约１８Ｍａ和最小滑动速率（１２±６）ｍｍ／ａ。后者（ＮＴ）表明在约８Ｍａ，即正断层运动开始时，西藏高原东南部地壳增厚和抬升可能已达到了近于现今的高度和水平。
