<P>This paper describes the architecture, design, analysis, and simulation and measurement results of the 3D-MAPS (3D massively parallel processor with stacked memory) chip built with a 1.5 V, 130 nm process technology and a two-tier 3D stacking technology using 1.2 \microm-diameter, 6 \micro m-height through-silicon vias (TSVs) and 3.4\nbsp\microm-diameter face-to-face bond pads. 3D-MAPS consists of a core tier containing 64 cores and a memory tier containing 64 memory blocks. Each core communicates with its dedicated 4KB SRAM block using face-to-face bond pads, which provide negligible data transfer delay between the core and the memory tiers. The maximum operating frequency is 277 MHz and the maximum memory bandwidth is 70.9 GB/s at 277 MHz. The peak measured memory bandwidth usage is 63.8 GB/s and the peak measured power is approximately 4 W based on eight parallel benchmarks.</P>

In this study a full scale 3D analysis of post-tensioned box section and pre-tensioned inverted T-girder section is carried out by considering only vertical loadings. The aim of this research is to investigate long span box Girder Bridge with pre-tensioned inverted T-girder using splicing technique. 4 lanes of 150m long (3 spans @ 50 m) post-tensioned box girder bridge with 12 cells and 13.54 m wide deck is considered as the bridge model and that the equivalent box section consists of 13 numbers of inverted pre-tensioned girder having two different lengths spliced at the points of inflection of continuous length of the bridge. The inverted T-girders are used to support the deck panel with superimposed load on it. The structural analysis of the bridge is done using CSi Bridge employing Integrated 3D Bridge Design Software based on finite element method for both longitudinal and transverse direction. In the analysis, AASHTO LRFD-2006 is used by subjecting Uniformly Distributed Load (UDL), edge loads, knife edge loads, and heavy vehicles load on the bridge deck. Moving vehicles load is placed at different locations to determine the maximum and minimum moments, stresses and flexural effects. Actual post-tensioned box section flexure, shear, torsion and stress in both longitudinal and transverse analyses showed lower values when compared to pre-tensioned inverted T-girder section. Assuming monolithic behaviour, the actual box section provided better stiffness rather than equivalent one. Nevertheless composite behaviour of the equivalent section can be accepted as an alternative solution for long span continuous box Girder Bridge where cost is a major factor in particular.

Virtual Machine (VM) resource management is crucial to satisfy the Quality of Service (QoS) demands of various multimedia services in a media cloud platform. To this end, this paper presents a VM resource allocation model that dynamically and optimally utilizes VM resources to satisfy QoS requirements of media-rich cloud services or applications. It additionally maintains high system utilization by avoiding the over-provisioning of VM resources to services or applications. The objective is to 1) minimize the number of physical machines for cost reduction and energy saving; 2) control the processing delay of media services to improve response time; and 3) achieve load balancing or overall utilization of physical resources. The proposed VM allocation is mapped into the multidimensional bin-packing problem, which is NP-complete. To solve this problem, we have designed a Mixed Integer Linear Programming (MILP) model, as well as heuristics for quantitatively optimizing the VM allocation. The simulation results show that our scheme outperforms the existing VM allocation schemes in a media cloud environment, in terms of cost reduction, response time reduction and QoS guarantee.

Wide range absorption is specially needed for different microtechnological applications along with microbolometers, photodetectors and coherent thermal emitters. Here we report, design of a wideband metamaterial absorber based on Titanium (Ti) and the analysis of its absorption and reflection characteristics. The structure of the absorber consists of two titanium layers spaced by a dielectric layer of refractive index 2. The simulation is done for analyzing its characteristics using finite difference time domain method (FDTD). The results show that the absorption occurs above 90 percent in the range 750 nm to 1200 nm while the reflection occurs below 10 percent. Overall absorption over the range (400 nm to 1500 nm) is found to be almost above 80 percent.

Lying is nuisance to all, and all liars knows it is nuisance but still keep on lying. Sometime people are in confusion how to escape from or how to detect the liar when they lie. In this research we are aiming to establish a dynamic platform to identify liar by using video analysis especially by calculating the ratio of changes in their appearance when they lie. The platform will be developed using a machine learning algorithm along with the dynamic classifier to classify the liar. For the experimental analysis the dataset to be processed in two dimensions (people lying and people tell truth). Both parameter of facial appearance will be stored for future identification. Similarly, there will be standard parameter to be built for true speaker and liar. We hope this standard parameter will be able to diagnosed a liar without a pre-captured data.

Vetiver grass (Vetiveria zizanioides) is being effectively used in many countries to protect embankment and slopes for their characteristics of having long and strong roots. In this paper, in-situ shear tests of the ground with the vetiver roots have been conducted to investigate the stabilization properties corresponding to the embankment slopes. Numerical analyses have also been performed with the finite element method using elastoplastic subloading $t_{ij}$ model, which can simulate typical soil behavior. It is revealed from field tests that the shear strength of vetiver rooted soil matrix is higher than that of the unreinforced soil. The reinforced soil with vetiver root also shows ductile behavior. The numerical analyses capture well the results of the in-situ shear tests. Effectiveness of vetiver root in geotechnical structures-strip foundation and embankment slope has been evaluated by finite element analyses. It is found that the reinforcement with vetiver root enhances the bearing capacities of the grounds and stabilizes the embankment slopes.

The shrimp export industry contributes significantly to Bangladesh’s economy, and is having a positive impact on the livelihoods of many. However, in contrast to small-holder farmers, the role of the shrimp industry in reducing poverty among the most marginalized households, who lack land or access to other resources, has been disappointing. In order to better understand why, the present study was designed to determine the roles of marginalized households in the shrimp value chains of coastal Bangladesh. Both quantitative and qualitative data were collected through field surveys, focus groups and in-depth interviews in the Khulna, Bagerhat and Satkhira districts. We find that about 46% of marginalized households are engaged in shrimp value chains and added some value in each node for an average of seven months a year. Their roles were wild shrimp fry catching and trading, shrimp PL (postlarvae) collection and trading, PL numerating, PL growing-out, shrimp trading, deheading, cleaning, icing and preserving. As laborers, the role of marginalized household members in the governance structure of the value chain was insignificant, and they have limited bargaining power. Nevertheless, they contribution added value at each node of the value chain, and their labor contribution was indispensable to the functioning of the chains.

Brucella spp. are small, non-motile Gram-negative coccobacilli known to cause disease in a number of vertebrate species including humans and brucellosis is one of the world's major zoonoses, alongside bovine tuberculosis and rabies. There are about 33.55 million goats and 1.16 million sheep in Bangladesh. The sheep and goats can significantly play an important role in the economic well being of the resource-poor farmer in Bangladesh. Sexually matured 362 female small ruminants(300 goats and 62 sheep) were examined. Approximately 3-5 ml of blood was collected from the jugular vein of each animal and sera samples were prepared. Samples were then tested for brucellosis by using Rose Bengal test(RBT), plate agglutination test(PAT) and tube agglutination test(TAT). Among 362 small ruminants, irrespective of species(sheep or goat), diagnosed highest in TAT, 2.21%(n=8) and lowest both by RBT & PAT, 1.93%(n=7) and it is concluded that TAT is superior than RBT and PAT.

The utilization of carbonaceous reinforcement-based polymer matrix composites in structural applications has become a hot topic in composite research. Although conventional carbon fiber-reinforced polymer composites (CFRPs) have revolutionized the composite industry by offering unparalleled features, they are often plagued with a weak interface and lack of toughness. However, the promising aspects of carbon fiber-based fiber hybrid composites and hierarchical composites can compensate for these setbacks. This review provides a meticulous landscape and recent progress of polymer matrix-based different carbonaceous (carbon fiber, carbon nanotube, graphene, and nanodiamond) fillers reinforced composites’ mechanical properties. First, the mechanical performance of neat CFRP was exhaustively analyzed, attributing parameters were listed down, and CFRPs’ mechanical performance barriers were clearly outlined. Here, short carbon fiber-reinforced thermoplastic composite was distinguished as a prospective material. Second, the strategic advantages of fiber hybrid composites over conventional CFRP were elucidated. Third, the mechanical performance of hierarchical composites based on carbon nanotube (1D), graphene (2D) and nanodiamond (0D) was expounded and evaluated against neat CFRP. Fourth, the review comprehensively discussed different fabrication methods, categorized them according to performance and suggested potential future directions. From here, the review sorted out three-dimensional printing (3DP) as the most futuristic fabrication method and thoroughly delivered its pros and cons in the context of the aforementioned carbonaceous materials. To conclude, the structural applications, current challenges and future prospects pertinent to these carbonaceous fillers reinforced composite materials were elaborated
