About this Item

Neuware - Advances in Engineering Research. Volume 25 examines the background of magnetic sensors within the field of traffic engineering. Starting off with an introduction to the principles of traffic detection and estimation, the authors study the design and development of a low cost, energy efficient multi-function wireless traffic earth magnetic sensors (EMS). Recommended sensor layout strategies are presented in an effort to reduce the investment cost and provide a decision-making basis for traffic management. Next, the authors present the main advantages of the vortex and highly turbulent flows and their implementation area in the chemical engineering. The technological scheme includes devices with active hydrodynamic regimes used in the granulation processes. The theoretical bases for the technological line of the devices with active hydrodynamic regimes is also presented. Piezoelectric materials were discovered many years ago, however, new compounds and fabrication techniques are continually explored in order to get the optimal and new properties. The authors discuss a new piezoelectric ceramic with Platinum implant that has been fabricated in recent years. The application possibilities of this ceramic are increased since there is a third electrode available which can be used to control its behavior. The analysis of the behaviour of Passive Magnetic Bearing (PMB) in order to achieve an acceptable magnetic force and stiffness is proposed as an interesting topic for rotating systems. In this compilation, numerical analysis, which is an effective method to investigate the structural parameters of PMB, is applied using Finite Element Method to the two-dimensional model of PMB. The closing paper presents a universal solution for the magnetic force interaction calculation between arbitrarily magnetized permanent ring magnets. The configuration contains two permanent ring magnets that correspond to the axial or radial passive magnetic bearing configuration, and the type of the bearing depends on the permanent magnets magnetization vector direction and the permanent magnets position.

About this title

Synopsis

In the opening chapter of Advances in Engineering Research. Volume 23, the authors describe the unique challenges of the logging tool hardware, measurements, and the spin-dynamics modeling, as well as data processing. The second part of the chapter describes typical NMR pulse sequences that are used for logging measurements, NMR responses for fluids in rock pore systems, and the petrophysical interpretation models and methodologies for petroleum reservoir formation evaluation. Next, the laws of rolling are derived in terms of elastic and geometric properties of rolling bodies and foundations. The rolling resistance coefficient was analytically calculated in the cases a) an elastic cylinder rolling over another elastic cylinder of another material, in particular, over an elastic half-space, and an elastic wheel rolling over the rail of another elastic material; b) an elastic ball rolling over another elastic ball of another material, particularly over an elastic half-space; c) an elastic torus rolling over an elastic half-space of another material; and d) a cylinder, or a ball, or a torus rolling over a tightly stretched membrane or over a thin elastic plate. This collection also deals with pressure tests conducted in EOR (enhanced Oil Recovery) projects where heat has caused changes in the viscosity of the reservoir fluids, which creates a difference in mobility between two zones of the reservoir. Under those conditions, the reservoir becomes a composite with two different zones. As inaccurate results will be obtained if the interpretation of well tests is not conducted properly, the authors present a practical methodology for interpretation. Next, the different trajectory inhibitory effects of laser re-melting on coating microstructure defects are discussed
