Das Buch befasst sich mit der Anwendung der dielektrischen Erwarmung mit Radiowellen auf unterschiedlichen Gebieten der Umwelttechnik. Im Mittelpunkt stehen die Aufheizung von Schuttbetten aus Adsorbenzien und Katalysatoren sowie die thermisch unterstutzte Reinigung kontaminierter Boden und Feststoffe. Aus stofflicher Sicht wurde die Erwarmung technisch relevanter Feststoffe wie Aktivkohlen, Molekularsieben (Zeolithen) und anderer Katalysatoren ebenso wie die Behandlung von Modellboden und realen Bodenproben untersucht. Die durchgefuhrten physikalisch-chemischen Grundlagenuntersuchungen bezogen sich vor allem auf die Fragen, inwiefern sich die Radiowellen-Erwarmung von konventionellen Heizmethoden unterscheidet, und ob und unter welchen...

Traditional stamping technologies that sheet sandwich a metal between the punch and have several inherent limitations such as the use of heavy tools, localized deformation that damage the parts and inhibit consistency. High speed forming is a light weight tooling assembly that forms the part without using any punch. Electromagnetic forming is a high speed forming technology that is used for embossing fine surface features onto sheet metals. The dynamics of sheet metal impact is presented through a simulation study. The primary objective of this work is to illustrate the utility of the numerical models for experimental design of flat- ridged parts. Critical factors that influence the product quality are investigated. The high impact...

Coal liquefaction was usually carried out at temperature higher than 400°C and at relatively high pressure. Many attempts have been made to develop methods of dissolving coal at less severe conditions in order to increase coal liquefaction efficiency and also to reduce capital and operation cost. In this investigation, three different types of pretreatments i.e. solvent swelling, in-situ solvent soaking and heating, and microwave irradiation have successfully been applied to untreated low rank Malaysian coal prior to liquefaction. The main objective of the pretreatments is to further enhance coal conversion and oil yield at less severe liquefaction conditions and this was successfully achieved for all the applied pretreated coals. A...

Die vorliegende Arbeit beschaftigt sich mit der direkten Drehmomentenregelung (engl.: direct torque control, kurz DTC) von Drehfeldmaschinen. Die Grundidee dieses Verfahrens besteht darin, das Drehmoment direkt uber das Aufschalten eines geeigneten Spannungszeigers zu beeinflussen. Der Standerfluss der Maschine wird dabei auf einer Kreisbahn mit konstantem Radius gehalten. Die Vorteile dieses Verfahrens liegen auf der Hand: Zum einen erfolgt die Regelung im feststehenden Standerkoordinatensystem, zum anderen ist es moglich, den teuren Drehzahlgeber einzusparen. Daruber hinaus kann die Maschine mit Hilfe der DTC sehr schnell auf Anderungen des Drehmomentsollwerts reagieren. Als Nachteile sind ein hoher Drehmoment- und Stromripple, sowie...

In this book, approximate dynamic programming (ADP) designs based on adaptive critic structures are developed to solve the discrete-time optimal control problems in which the state and action spaces are continuous. This work considers linear discrete-time systems as well as nonlinear discrete- time systems that are affine in the input. This work resulted in forward-in-time reinforcement learning algorithms that converge to the solution of the Generalized Algebraic Riccati Equation (GARE) for linear systems. For the nonlinear case, a forward-in-time reinforcement learning algorithm is presented that converges to the solution of the associated Hamilton-Jacobi Bellman equation (HJB).

The discrete gradient method is proposed as a novel numerical tool to perform solid mechanics analysis directly on point-cloud models without converting the models into a finite element mesh. This method does not introduce continuous approximation of the primary unknown field variables; instead, it computes the gradients of the field variables at a node using discrete differentials involving a set of neighboring nodes. Therefore, the formulation renders a completely discrete computation that can conduct mechanical analysis on point-cloud representations of patient- specific organs without resorting to finite element method.

This book provides the effect of dispersion and Multi Access Interference (MAI) of optical fiber on the Bit Error Rate (BER) performance of a Direct Sequence Optical Code Division Multiple Access (DS- OCDMA) network by means of intensity modulation and optical receiver correlators. By using Matlab simulations, Signal-to-Noise Ratio (SNR) versus Received Optical Power (ROP) of an OCDMA transmission system can be evaluated with a so-called 7-chip m-sequence for different numbers of system users. This can be done for the ROP versus BER for various lengths of single mode optical fiber by taking into consideration the dispersion effect in the optical fiber. Matlab simulations can be performed in order to illustrate the reduction of the...

The optical signals pass through a number of components such as optical fibers, filters, multiplexers and switches. These components increase the amount of total dispersion. Dispersion or pulse spreading of the optical signals is a problem which limits the bandwidth and length of the information carrying fiber. Therefore, it is important to control and characterize the dispersion. In this work, our target is to find and characterize the wavelength dependence dispersion and to see the effect of fiber Bragg grating (FBG) as a dispersion compensator. A 100 km single mode (SM) fiber optic link has been chosen. Laser diode has been chosen for light source. The channel achieve a BER = 10 -11 after propagating through the 100 km single-mode...

Dissolved air flotation is a water treatment process that clarifies wastewaters by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank or basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.

The monograph is a contribution to the recently very active field of swarm analysis and distributed control of networked autonomous robots. It contains sufficient scientific contributions and timely ideas for applications. From the perspective of interacting dynamical systems and associated interaction graphs, remarkable mathematically rigorous results are developed, which explain how global collective behaviors emerge from purely local interaction and are essential in synthesizing cooperative control for distributed autonomous robotic systems. These results are treated to be fundamental in the field. Данное издание не является оригинальным. Книга печатается по технологии...

High Quality Content by WIKIPEDIA articles! A doomsday device is a hypothetical construction — usually a weapon — which could destroy all life on a planet, particularly the Earth, or destroy the planet itself (bringing "doomsday", a term used for the end of planet Earth). Most hypothetical contructions rely on the fact that hydrogen bombs can be made arbitrarily large assuming there are no concerns about delivering them to a target (see Teller–Ulam design) or that they can be "salted" with materials designed to create long-lasting and hazardous fallout (e.g.; a cobalt bomb). Doomsday devices have been present in literature and art especially in the 20th century, when advances in science and technology made world destruction (or at...

The CW-Radar measures the Doppler-frequency of the microwave radiation: A wave of fixed frequency (Continuous Wave, CW) is radiated through a high-gain antenna onto a moving target where it is reflected and the reflected wave is received by the radar antenna again. The reflected wave exhibits a frequency shift (Doppler-frequency) which is proportional to the radial velocity of the target and proportional to the frequency of the transmitted wave. This wave has frequency 24GHz, generated in the transmitter and after that there are some of parts. The thesis task is to build one part of a radar system which operates at 24 GHz, namely the building block that takes-in the 12 GHz oscillator signal to double the frequency to 24 GHz and amplify...

Dragline excavation systems are heavy equipment used in civil engineering and surface mining. In civil engineering the smaller types are used for road and port construction. The larger types are used in strip-mining operations to move overburden above coal, and for tar-sand mining. Draglines are amongst the largest mobile equipment (not water-borne), and weigh in the vicinity of 2000 metric tonnes, though specimens weighing up to 13,000 metric tonnes have also been constructed. A dragline bucket system consists of a large bucket which is suspended from a boom (a large truss-like structure) with wire ropes. The bucket is manoeuvred by means of a number of ropes and chains. The hoist rope, powered by large diesel or electric motors,...
