in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
Midlatitude Synoptic Scale Systems: Their Kinetic Energy Budgets and Role in the General Circulation
The kinetic energy budgets of several examples of synoptic scale systems are reviewed. Included are systems containing a major cyclone development, the immediate cyclone vicinity, and the anticyclone preceding the cyclone development. These are then considered in terms of their role in the general circulation of the middle latitudes. Results show that the cyclone system and cyclone vicinity are...
â â â aside from its annual and seasonal fluctuation, caspian sea level has sudden change with hourly and daily continuity caused by atmosphere circulation patterns. sometimes these fluctuations are so intense that they make irreparable damage to the economical and social activities in the coastal sea areas. the aim of this study is synoptic recognition of factors causing storm levels in the s...
Satellite ocean-color imagery and field spectroradiometer observations are used to assess the biooptical signatures of two mesoscale features, a cyclone C1 and an 181-water anticyclone A4, in the Sargasso Sea. Field determinations of upper layer bio-optical properties, such as the diffuse attenuation coefficient and remote-sensing reflectance spectra, show little statistically significant varia...
this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
dust storms are destructive climate phenomenon which damage farm, installations,roads,traffic and etc indemnifiable. this phenomena at dry and pertaining regions of the country as environmental perils, is effected by particular atmospheric condition.if the origin and extention of this phenomenon be recognized the damages can be decreased or counteracted.the studied about dust storm show thirtee...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
Some investigations were made on the wave height and wave period of wind waves and swells, based on the data of .continuous observation of ocean waves with a self-registering wave gauge at Jogashima Island, Kanagawa Prefecture, Japan, duriug a year from September, 1951 to August, 1952, and the characteristics of variations of wave height and wave period and their relations to meteorological con...
