Authors: Han Ming , Wang Ping , Pang Hui Fang , Liu Fu Qiang , Wang Xin Hong , Nguyen Ngoc Van
Published: December 2013

D2D communication can facilitate diverse local services and ease the load of base station. However, traditional resource allocation schemes for D2D communication were simply aiming at maximizing the sum-rate capacity or minimizing the mutual interference of the system but ignoring users satisfaction, which were discussed usually under the premise that the system resource was sufficient for the fixed number of users or restricted in the flexibility of spectral reuse. In the resource constrained system, aiming at maximizing average system satisfaction degree, a more flexible resource allocation scheme based on optimized artificial fish swarm algorithm (USRA-AFSA) is proposed in this paper, in which user satisfaction degree models are established and different D2D links are allowed to coexist on the same subchannel. With solutions mapped onto artificial fish, the simulation results show that the proposed scheme achieves higher average system satisfaction degree and larger system throughput compared with other schemes.

The algorithm is supposed to solve the issue that the channel estimation result is not accurate when the training sequences have some 0 elements. The improvement is also applicable in the other channel estimation algorithms. We made some comparisons between the linear least squares (LS) and the linear minimum mean square error (LMMSE) channel estimation, the traditional singular value decomposition and the improved SVD algorithm to demonstrate the efficiency. Results show that the proposed improved SVD algorithm has better performance in mean square error (MSE) and bit error rate (BER) of channel estimation and the estimated values approach the actual channel state.

Authors: Zhang Jian Jun , Qu Yong , Mei Dan
Published: December 2013

The scheduling of Out-Tree task graphs is one of the critical factors in implementing the compilers of parallel languages and improving the performance of parallel computing. When applied to Out-Tree task graphs, many previous classical heterogeneity based algorithms always ignored the economization on processors and the minimization of the schedule length, which led to low efficiency in real applications. This paper proposes a heterogeneity based greedy algorithm for scheduling Out-Tree task graphs, which is based on list and task duplication, tries to find the best point between balancing loads and shortening the schedule length and improves the schedule performance without increasing the time complexity of the algorithm. The comparative experimental results demonstrate that the proposed algorithm could achieve shorter schedule length while using less number of processors.

Published: December 2013

The maturity behavior of cement mortar specimens with different concrete additives during the 28 day curing period has been examined using the AC Impedance technique. The main focus of this part of the study is to understand the impedance and capacitance behavior of the steel rebar in cement mortar using different additives during the early stages of hydration process. In this respect, two sets of specimens were prepared: One set consist of two graphite electrodes surrounded by a carbon steel rod for AC Impedance measurements. Another set consisted of two carbon steel setup that has been used for monitoring corrosion of two steel reinforcement bars embedded in cylindrical mortar specimens. The specimens are placed in a salt fog (spray) cabinet for 1,000 hrs.Galvanic current between the two coupled electrodes has been measured using zero resistance ammeter (ZRA) to monitor the extent of corrosion. The in-situ measurement was carried out in a sequential manner over a periodical basis of up to 1,000 hrs of salt fog cabinet exposure. Different mortar mixes were studied including ground granulated blast furnace slag (GGBS) and silica fume (microsilica) as additives and calcium nitrite as corrosion inhibitor and chloride as a contamination species. This data helps in understanding the corrosion activities at the rebar-concrete when interface combined with salt fog test according to (ASTM B117), which can be further correlated with the atmospheric and marine corrosion of steel rebars in concrete. The overall results have indicated the tendency of the admixture to show different hydration processes during the early stages of concrete curing. The interfacial impedance spectrums and galvanic current testing clearly identifies and documents this process for each material.

This paper presents a discussion of factors affecting the performance of fly ash based geopolymer, and some recent innovations on fly ash based geopolymer. The characteristics of fly ash based geopolymer are discussed in terms of the effects of raw material selection, alkaline activators, and curing procedures. Nowadays, researchers have used geopolymer as a cementitious material to develop innovative geopolymer materials, such as porous, fibre reinforced and foam fly ash based geopolymer concrete, which are greener than the traditional cementitious material. The high-calcium fly ashes could be used to produce porous fly ash based geopolymer composites with satisfactory mechanical properties. The addition of fibres increases greatly the ductility of geopolymer. Foam can be added to the geopolymeric mixture to produce lightweight concrete. However, the manufacturing of fly ash-based geopolymer foam concrete has not been explored too much.

The point of this study was to assess the progressive collapse resisting capacity of special steel moment frame structures and the behaviour of buildings which have different height when they are losing one of their exterior columns. Two buildings were considered for this research, 7-storiy and 12-storiy buildings. Corner column as well as one of the middle columns was removed to evaluate the importance and the effect of the location of removed column in structural response. General Services Administration (GSA) and Department of Defence (DoD) guidelines are considered for choosing the method of analysis. Nonlinear dynamic analysis procedures were carried out to investigate the behavior of structures. Thus, maximum vertical displacement in the point of column removal for each structure was measured. In addition, both buildings have cover plate connections which are cosidered to be rigid in modelling.

Many traditional forecasting platforms try to make predictions about the future by analyzing patterns that occurred in the past.More sophisticated methods exist, such as exponential smoothing or the Holt-Winters method. Nonetheless, as sophisticated as these methods are, they all suffer from the same deficiency: they only consider the past. While the past is indeed a statistically significant indicator of what will happen in the future, it isnt the only indicator. In multi-echelon supply chain systems, there exists a plethora of highly relevant data that can be tapped into.We have built an Arena model to simulate our manufacturing plants supply chain. As we go forward, we will explain how this model was used to explore the significance of various external data sources such as DC and store inventory levels, open orders, and lead times. Using these findings, we derive a regression-based forecasting algorithm that improves accuracy by 35 percent. More accurate forecasts allow our company to maintain a higher service level, lower safety stock, and a more predictable transportation schedule, all of which lead to significant cost savings.
