für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Many older structures were designed for static loads but more recently there has been a growing awareness that some must be designed to resist both dynamic impact and static loads. An accidental impact load can be caused by mishaps in industry as well as accidents stemming from transportation or man-made disasters. Structural components can be subjected to a range of deliberate impact loads such as military activity or terrorist attacks. A large proportion of the surfaces of concrete structures are covered by reinforced concrete slabs. Slabs are often slender elements, which means they are vulnerable to flexural, shear, or a combination of both modes of failure when subjected to impact loading. There are a number of ways of predicting how an impact load will affect a concrete slab, some of which may be impractical or expensive but because there have been significant developments in technology, numerical techniques rather than experimental approaches have become popular methods for developing detailed responses. ····· 10361101121
····· lezzter Preis 44.10€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This work presents new approaches for motion design and analysis suitable for the integration of Computer Aided Design (CAD), Computer Aided Manufacturing (CAM) and Computerized Numerical Control (CNC). Therefore, not only shape but also kinematic information is conveyed in an efficient manner that can be easily implemented in CAD/CAM systems and eventually interpreted by CNC manufacturing equipment. By using dual quaternions, quaternions and planar quaternions, the displacements of a rigid body in Cartesian space are mapped into points in the image space of displacements, transforming the kinematic problem of motion interpolation into a geometric problem where the powerful techniques for curve and surface interpolation from Computer Aided Geometric Design (CAGD) can be readily applied. Three techniques are developed using quaternion biarcs, a four point interpolatory subdivision scheme and its tensor product version. A preliminary approach for mechanism simulation using subdivision schemes is also attempted. The results obtained have applications in CNC tool path generation, robot path planning, and computer animation. ····· 10361101120
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book introduces a new optimization algorithm for simulation-based design of systems with multi-modal, nonlinear, black box objective functions. The algorithm extends the recently introduced adaptive multi-modal optimization by incorporating surrogate modeling features similar to response surface methods (RSM). The resulting optimization algorithm has reduced computational intensity and is therefore well-suited for optimization of expensive black box objective functions. The algorithm produces progressively accurate surrogate models around the local minima which can be used for post-optimization studies such as sensitivity and tolerance analyses with minimal computational effort. This algorithm is suitable for optimal design of complex engineering systems and enhances the design cycle by enabling computationally affordable uncertainty analysis. The mathematical basis of the algorithm is explained in detail. The book also demonstrates the effectiveness of the algorithm using comparative optimization of several multi-modal objective functions. It also shows several practical applications of the algorithm in the design of complex power and power-electronic systems. ····· 10361101119
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Owing to their distributed architecture, networked control systems are proven to be feasible in scenarios where a spatially distributed control system is required. However, basic networked control systems cannot operate over general purpose wireless networks since the stability of the system is compromised due to unbounded delays and unpredictable packet losses that are typical in the wireless medium. Approaching the wireless networked control problem from two perspectives, this book introduces a novel wireless networked control system and a realistic cooperative medium access control protocol implementation that work jointly to achieve decent control even under unbounded delay, bursts of packet loss and ambient wireless traffic. The proposed system is implemented and thoroughly evaluated on a dedicated test platform under numerous scenarios and is shown to be operational under bursts of packet loss and ambient wireless traffic levels which are intolerable for basic networked control systems. The methods covered in this book should assist in developing various wireless networked control systems and should be especially useful to practicing control engineers. ····· 10361101117

The diverse RFID applications and services necessitate collection and manipulation of integrated RFID-sensing information at the same system. Systems deploying sensor tag can achieve both ID data and sensing data simultaneously. Various applications require generation of tag status reporting, sensing threshold alarms, controlling of tag modes and states, and extraction of sensing data from tag memory. However, existing standards proposed by EPCglobal and ISO are limited only to RFID data manipulation and lacks efficient management of sensor tags. Therefore, a system is required to control and manage Sensor tag using existing standards. To resolve the above mentioned problems, this book proposes a new system architecture for Sensor Tag Management (SenTM). SenTM provides four types of service modules and APIs for efficient sensor tag management.It is a layered system based on EPCglobal Architecture Framework that provides compatibility and global interoperability of the system. ····· 10361101084

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Particulate fouling is defined as the accumulation of particles on a heat exchanger-surface forming an insulating powdery layer. Particulate fouling in biomass gasifiers is a major problem that may lead to inefficient operation, and it shows an asymptotic growth rate with a levelling off increase of the thickness. The fouling growth rate is determined by the difference between the deposition and the removal rate of particles on and from the fouling layer respectively. Till now, most attention has been given to the deposition process. The objective of this research project is to study and model removal of particles from particulate fouling layers as a function of the fouling layer structure. By integrating the removal rate and the depositing rate a complete perspective can be given about the fouling process. The removal and deposition of particles from particulate fouling layers as a function of the fouling layer structure have been numerically modelled and the model is experimentally validated. By combining the numerical model together with a CFD-particle transport model, the growth rate of the particulate fouling layer around a heat exchanger tube can be quantitatively predicted. ····· 10361100896

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The traditional approach for thermal insulation of cold piping is specifying either vapour-impermeable insulation material and/or a continuous vapour retarder on the warm side of the insulation to minimise vapour flow to the cold surface. In theory, these materials limit the rate of water vapour ingress to a level so low that the amount of condensed water is negligible. In practice, however, this approach requires that the vapour retarding system must be continuous at all the joints, elbows, valves and fittings present in real installation. The degree of success therefore depends heavily on both the installation and the degree of maintenance provided after installation. Even with the careful installation of vapour retarders, in conjunction with closed-cell insulation, a finite amount of water enters the system and cause the degradation of the insulation performance. An alternative approach is to utilize the wicking material to remove condensed water from the system while keeping the insulation material substantially dry. The document contains results of experimental testing, and should be especially useful to professionals in the Technical Insulation field. ····· 10361100802

The average dimension of the parts may shifts or drifts from the nominal value during the manufacturing process. And, the dimension distribution of the parts can be in different non- normal distribution since they are manufactured by different manufacture process. This method predicts more accurate resultants by an interpolation method. With this method, the assembled state of an assembly with multiple constraints can be evaluated. The assembly behaves a higher probability of stiffness, as if the minimum gap index is smaller. For the mean shift studied for the cases represented in this paper, the results show the difference between this model and the Monte Carlo method with 1,000,000 simulation samples is less than 0.5%. The two stack-up examples described in this paper show the predicted errors only 0.799% and -1.76% respectively.

These engines operate at temperatures well above the melting points of their parts, and rely on these coatings to help maintain engine integrity. The coating deposition process, however, has its drawbacks. Over the life of a plasma gun, adjustments to various inputs are needed to create a balance between process efficiency, coating thickness gain, microstructure, and surface roughness. To date, no single broad mathematical model fully describes the impact of these inputs. The purpose of this work was to identify and measure the significant factors that contribute to the variations in properties associated with a quality deposited plasma spray ceramic coating to eventually predictably control these inputs to maintain consistent coatings throughout the life of a plasma gun. ····· 10361100116· 1 · ::::: · 39 ·· 40 ·· 41 ·· 42 ·· 43 ·· 44 ·· 45 · ::::: · 83 ·
