für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Understanding creep behavior in rock piles under both dry and moist conditions will help to evaluate long-term stability of rock piles. The effect of compaction densities (1700 kg/m3 and 1850 kg/m3) on moist (8% water content) samples were also investigated for four shearing rates (0.5 mm/min, 0.05 mm/min, 0.0275 mm/min and 0.005 mm/min). Normal stresses of 160 kPa, 480 kPa and 750 kPa were used. The obtained internal friction angles versus rate of shear deformation were plotted in a semi-logarithmic format and the data show a fairly consistent linear trend. For both the dry and the moist Spring Gulch rock pile materials, the shear strain rates used in this study show no major effect on the shear strength of the material, even though the friction angle and cohesion intercept were affected by the deformation rate. The internal friction angle of the rock pile materials in moist conditions decreases with increasing compaction density. In addition, cohesion increases with increasing the compaction density by keeping the water content unchanged. ····· 10361115976

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The amount of collected data is increasing all the time in the world. Even though computers are getting faster and faster, large databases still need better and more accurate methodologies for them to be useful in practice. Some techniques are not feasible to be applied to very large databases or are not able to provide the necessary accuracy. This book focuses on two aspects encountered with databases, time series prediction and missing value imputation. Accurate prediction of future values is heavily dependent not only on a good model, which is well trained and validated, but also preprocessing, input variable selection or projection and output approximation strategy selection. On the other hand, missing values can be a nuisance, but can also be a prohibiting factor in the use of certain methodologies and degrade the performance of others. Hence, missing value imputation is a very necessary part of the preprocessing of a database. Furthermore, even though the accuracy is always the main requisite for a good methodology, this book touches the aspect of computational time, which has to be considered with the accuracy in order to reach good results. ····· 10361115943

Artificial neural networks (ANNs) and adaptive neuro fuzzy inference system (ANFIS) can enhance the performance of the motor by making a control system which would provide smooth starting to induction motor. Dynamic model of induction machine in different frames of reference was implemented using Matlab Simulink. Feed forward back propagation based and radial basis neural networks were trained, with data obtained using simulations, to estimate different parameters required by ANFIS to adjust firing angle of back-to-back connected pairs of thyristors in AC voltage controller. Inrush current and pulsations in torque were reduced significantly. Radial basis and feed forward neural networks were compared for off-line and on-line training, training time, memory required for implementations, number of neurons, computational procedures and algorithms, reliability of the system and most important cost of implementation.

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Multiple-input multiple-output (MIMO) techniques are the fundamental technology in several standardizations, including long-term evolution (LTE) and LTE-advanced. For instance, MIMO spatial multiplexing (MIMO-SM) is used to increase the system capacity without requiring additional time/frequency resources. However, the performance of the MIMO-SM depends on the employed detection algorithm. Also, multi-user MIMO precoding at the transmitter part is used to support the simultaneous transmission to several users. In this book, we review the basics of MIMO detection. Then, we introduce two detection algorithms, namely, adaptive parallel QRDM algorithm (APQRDM) that increases the detection throughput and adaptive iterative QRD-M algorithm (AIQRDM) that reduces the hardware requirements. Besides, these two algorithms adaptively reduce the computational complexity, while achieving the optimum diversity. Furthermore, in addition to introducing the state of the art of the precoding techniques, we propose a fixed complexity sphere encoder (FSE) that requires a fraction of the computations performed by the QRDM encoder, while achieving a tremendous increase in the precoding throughput. ····· 10361115460

Particulate reinforced aluminium matrix composites (AMCs) are attractive materials due to their strength, ductility and toughness. Their ability to be produced by conventional methods adds to the advantage. The aluminium matrix can be strengthened by reinforcing with hard ceramic particles like SiC, Al2O3 and B4C etc. Judicious selection of the variables is important to optimize the properties of composites. In this work an effort is made to enhance the mechanical properties like tensile strength and hardness of AMCs by reinforcing 6061Al matrix with B4C particles. By stir casting route, aluminium matrix was reinforced with boron carbide particulates of 37, 44, 63, 105, 250µ sizes.
