An evidence file is a bit-stream copy of any digital storage media or a hard disk partition. Retrieving files from these evidence files without the intervention of file system is quite challenging as the storage locations where file contents are stored are unknown or the contents of files are unavailable in contiguous storage locations. In addition to this, portion of some of the deleted files might have been overwritten by new files. In this paper, we propose a method to carve bitmap files from evidence files by making use of the presence of slack area in the evidence file. The contiguous file filtering technique proposed in this paper makes the carving of fragmented files easier. © 2012 Springer-Verlag.

Measurements of ZZ production in the ℓ+ℓ−ℓ′+ℓ′− channel in proton–proton collisions at 13 TeV center-of-mass energy at the Large Hadron Collider are presented. The data correspond to 36.1 fb−1 of collisions collected by the ATLAS experiment in 2015 and 2016. Here ℓ and ℓ′ stand for electrons or muons. Integrated and differential ZZ→ℓ+ℓ−ℓ′+ℓ′− cross sections with Z→ℓ+ℓ− candidate masses in the range of 66 GeV to 116 GeV are measured in a fiducial phase space corresponding to the detector acceptance and corrected for detector effects. The differential cross sections are presented in bins of twenty observables, including several that describe the jet activity. The integrated cross section is also extrapolated to a total phase space and to all standard model decays of Z bosons with mass between 66 GeV and 116 GeV, resulting in a value of 17.3±0.9[±0.6(stat)±0.5(syst)±0.6(lumi)] pb. The measurements are found to be in good agreement with the standard model. A search for neutral triple gauge couplings is performed using the transverse momentum distribution of the leading Z boson candidate. No evidence for such couplings is found and exclusion limits are set on their parameters.

Although superstores can help visually impaired customers with their in-store shopping, they cannot help them identify the products after the customers take them home. We designed a QR-Label and realized an on-demand printing system for superstores. Visually impaired customers can listen to product information at home through their mobile phone by using it to scan the QR-Label placed on each of the purchased packages. © 2013 IEEE.

Most digital cameras use color filter arrays of different patterns to capture color image. The output of the color filter array is a sampled version of the original color image. Demosaicing algorithms are used to reconstruct the original color image from this sampled version. Medical image analysis is increasing day by day. The amount of data to be saved is also on the increase. Standard compression techniques like JPEG if used may cause loss of diagnostic data which cannot be tolerated. So if a proper demosaicing algorithm can be found such that there is not much loss of data in reconstruction then the images can be saved in raw format and color image can be reconstructed using this algorithm, when needed, leading to a great amount of compression. This paper studies and compares different existing demosaicing algorithms to find a suitable algorithm for this application. © 2012 IEEE.

The field of Electronics and Communication Applications, especially the VLSI design, has witnessed tremendous changes on account of research and development in SoC (System-on-Chip) technology during the last four decades. The introduction and advancement of multimillion-gate chips technology with new levels of integration has been mainly responsible for these revolutionary changes. It is predicted that by the end of 2015 System-on-Chips (SoCs), using 25-nm will grow to 17 billion transistors running at 30GHz. In the modern scenario of IP reuse, the compatibility of the IP cores has become a challenging task as the cores available for reuse and designed earlier, are usually designed with different criteria, and may be having inconsistency between their input/output port specifications. This paper endeavors to address the above problems and challenges in the SoC bus architecture with special reference to Wishbone bus architecture especially Wishbone bus interface. A SoC which utilizes ALU master cores and memory slave cores using Wishbone Dataflow bus interconnection scheme has been designed for this purpose. The final implementations have been done in XILINX FPGA platform. The synthesis of the system is done using Xilinx 12.3 ISE and simulation results archived by using ISim Simulator. The results prove that with Dataflow interface architecture a low cost, portable and Time to market SoC having features like Less Area and High Speed can be designed successfully.

Electronic tongue has already been used to estimate the quality of tea in terms of tea-tasters scores that are subjective and limited by human sensory organs. It is known that, chemical constituents play significant role to determine the quality of tea. Thus the perception of quality as understood from an electronic tongue can be improved if it can be trained to estimate the amount of major chemicals responsible for quality of tea. An alternate method of rapid quality evaluation of tea is proposed using a voltammetric electronic tongue to determine two major taste descriptors in black tea. The correlation model is developed between the electronic tongue signatures and theaflavins/thearubigins contents of tea using multi-layer perceptrons. The perception of taste is further improved using scaled conjugate gradient as a weight optimization algorithm. © 2012 Springer-Verlag.

Grid computing is a collaborative e-infrastructure to solve large multidisciplinary problems having interrelated demands of data, compute, scientific instruments and increased importance of collaboration. Grid is a distributed system which enables sharing, selection, and aggregation of heterogeneous geographically distributed autonomous resources dynamically depending on their availability, capability, performance, and users QoS requirements. Validating such a vast system has additional complexities of heterogeneity, multiple administrative policies, and issues of multi-layer software interactions. GARUDA is the Indian National Grid computing Initiative connecting over 65 partnering institutes across 30 cities of India and aggregating over 70TF-15TB Compute-Storage power. The authors present the software engineering challenges and validation methodologies for GARUDA, to make it a production level grid. Integrated validation of GARUDA through Application testing, Health Monitoring, Middleware-Software testing, Performance benchmarking and Stress testing are described.

The performance (in terms of accuracy and speed) of present day document analysis systems, both handwritten and printed, depends on the preprocessing stage. In the existing literature we observe accuracy against speed trade-off. That is, superior binarization accuracy is arrived at the cost of increased processing time. The present paper proposes an improved binarization approach, which after a Pre Segmentation Binarization uses a state-of-the-art “fringe map” based text line segmentation algorithm to define text context. This text context is exploited to provide a more refined localized binarization (Post Segmentation Binarization). This unique combination gives benefits of both speed and accuracy with a scope of leveraging through parallel processing. It may additionally be used on skewed or warped camera captured document images. Experimental tests on ICFHR-DIBCO 2009, 2010 and 2011 databases of Printed/ Handwritten Document Images have shown promising results.
