Velocity determinations

In this paper, the problem of how to apply PSPI Migration to interpret GPR data will be presented. Some results of model datum and real datum were also examined. Besides, we made a comparison of using RMS velocity and interval velocity, and then explain how these two types of velocity could be combined to receive the best result

Theoretical study of earthquakes as well as practical application is actually important to determine the earthquake hazard assessment and risk in a specific region. This is probably the most important contribution of seismology to society. recent earthquake showed the inadequacy of a large part of the building construction in and around the epicentral area, so the study of earthquakes has become and more important.

Cinema is meant and believed to entertain, to take the viewer to a world that is starkly different from the real one, a world which provides escape from the daily grind of life. Cinema is a popular media of mass consumption which plays a key role in moulding opinions, constructing images and reinforcing dominant cultural values. The paper deals with representations of women characters in mainstream Bollywood movies.

Control analysis of the glycolytic flux was carried out in two fastgrowth tumor cell types of human and rodent origin (HeLa and AS30D, respectively). Determination of the maximal velocity (Vmax) of the 10 glycolytic enzymes from hexokinase to lactate dehydrogenase revealed that hexokinase (153–306 times) and phosphfructokinase1 (PFK1) (22–56 times) had higher overexpression in rat AS30D hepatoma cells than in normal freshly isolated rat hepatocytes.

The publication of the Hipparcos and Tycho Catalogues in 1997 transformed astrometry, and as a consequence astronomers’ perception of astrometry. What had before often been regarded as a somewhat quaint specialty of limited relevance to modern astrophysics, was suddenly seen to produce a wealth of data of immediate practical use. The ready availability of many thousand precise trigonometric stellar distances and the access to an accurate and dense optical reference frame have changed the way astronomers think about certain problems and plan their experiments....

In this research, properties of ultrasonic waves transmitted in some carbon steels were investigated. Base on ultrasonic measurements for the steel samples of X40H, S45, SCM420, and SCR420, the values of ultrasonic wave velocities including longitudinal and transverse velocities were determined. These measurements also used to obtain ultrasonic attenuations of these steel samples. Based on ultrasonic velocities, the mechanical properties of these steel samples were calculated including Poisson’s Ratio υ, Young’s modulus E, and Shear modulus G.

Determining the stability conditions of the track driven vehicle while stair climbing and descending
This article presents the method of determining the stability limit of the vehicle (robots or electric wheelchairs) that use tracks (chain, belt) for climbing and descending stairs. Research method was conducted by modeling vehicle which is working under the influence of some elements such as geometric, mass, velocity, acceleration, friction...Afterthat, we identify some conditions which lead to tipping.

Models for Dynamic Systems. Since their introduction by Isaac Newton in the seventeenth century, differential equations have provided concise mathematical models for many dynamic systems of importance to humans. By this device, Newton was able to model the motions of the planets in our solar system with a small number of variables and parameters. Given a ®nite number of initial conditions (the initial positions and velocities of the sun and planets will do) and these equations, one can uniquely determine the positions and velocities of the planets for all time....

Geometry and Trigonometry Geometry and Trigonometry Although many people find geometry and trigonometry intimidating, the small investment required to understand a few basic principles in these disciplines can pay large dividends. For example, what if you needed to find the distance between two points, or rotate one object around another? These small tasks are needed more often than you may think, and are easier to accomplish than you may realize. Movement Along an Angle Earlier we discussed velocity as a vector quantity because it combined magnitude and direction.

The chapter on uniform flow in open channels is basic knowledge required for all hydraulics students. In this chapter, we shall assume the flow to be uniform, unless specified otherwise. This chapter guides students how to determine the rate of discharge, the depth of flow, and the velocity. The slope of the bed and the crosssectional area remain constant over the given length of the channel under the uniformflow conditions. The same holds for the computation of the most economical cross section when designing the channel.

Twoaxle vehicles without trailer Low speed or kinematic steering is, as already stated, deﬁned as the motion of a wheeled vehicle determined by pure rolling1 of the wheels. The velocities of the centres of all the wheels lie in their midplane, that is the sideslip angles αi are vanishingly small. In these conditions, the wheels cannot exert any cornering force to balance the centrifugal force due to the curvature of the path. Kinematic steering is possible only if the velocity is vanishingly small.

Distribution Management (DM), formerly known as Velocity Management (VM), is an Army initiative to dramatically improve the performance of key logistics processes: distribution, repair, stockage determination, and financial management. This monograph describes how the then Velocity Management initiative was used to develop and implement a new algorithm for computing inventories maintained by Army supply support activities (SSAs). The new algorithm is called dollar cost banding (DCB), and it departs in important ways from the methodology that the Army had been using.

In this paper, a method which intends to provide the motion in every point of the path with possible maximum velocity is described. In fact, the path is divided to transient and cruising parts and the maximum velocities are required only for the latter. The given motion is called “Timeoptimal cruising motion”. Using the parametric method of motion planning, the equations for determining the motions are given.
