A Survey of Techniques for Answering Top-K Queries
No full textTop-k queries are useful in retrieving top-k records from a given set of records depending on the value of a function F on their attributes. Many techniques have been proposed in database literature for answering top-k queries. These are mainly categorized into three: Sorted-list based, layer based and View based. In first category, records are sorted along each dimension and then assigned a rank to each of the records using parallel scanning method. Threshold Algorithm (TA) and Fagin2019;s Algorithm (FA) are the examples of sorted-list based category. Second category is layer based category, in which all the records are organized into layers such as in onion technique and robust indexing technique. Third category includes methods such as PREFER and LPTA (Linear Programming Adaptation of Threshold Algorithm) and processing is based on the materialized views
Sensitivity Analysis of Rectangular Microcantilever Structure with Piezoresistive Detection Technique Using Coventorware FEA
No full textAbstractMicro Electro Mechanical Systems (MEMS) based microcantilever is a micromachined device similar to the miniaturized version of a diver's board, longer as compared to width, and has a thickness much smaller than its length or width. The merits of MEMS microcantilever sensors are its high sensitivity, design simplicity, portability and high speed. In this paper, a microcantilever sensor is designed to meet the requirements of a biosensor that detects tuberculosis. The addition of mass on the microcantilever surface makes it to bend and its stressed elements deform.The deflection underwent by microcantilever is detected by piezoresistive detection mechanism. The behavior of piezoresistive microcantilever structure is investigated using various beam materials and geometric dimensions. The advantage of incorporating SCR (Stress Concentrated Region) on the piezoresistive microcantilever is studied and the optimal position of placing the piezoresistor on the microcantilever beam is investigated using load analysis and corresponding stress distribution results. CoventorWare® is used to do the analysis of micromachined cantilever. The results show that sensitivity increases with increase in length and incorporation of SCR but decreases with increase in thickness
Reliability of Ultimate Limit State Design in Finite Elements and Compliance with Eurocode 7
No full textGeotechnical design problems may be characterized by a certain degree of uncertainty, due to insufficient soil data and transformation of test results in soil parameters. In common practice, engineers perform deterministic analyses according to design standards as Eurocode 7, where the uncertainties are taken into account through partial factors for loads and soil properties to attain certain specified target reliabilities. Forcomplexsoilstructureinteractionproblems, partialfactormethodis difficult to adopt, as the design standards consider geotechnical standards with singlefailuremechanism. ThisisespeciallyproblematicforUltimateLimitstatedesigns where both stiffness and strength properties are dominant. With the advent of limit state design philosophy in Eurocodes, the use of reliability methods in Finite Element Analysis for complex situations has become more and more of interest. Reliability analyses allow to explicitly define the single uncertainties in the model by using an appropriate probabilistic distribution for each source of uncertainty. The reliability index and the probability of failure with respect to a predefined condition are calculated. The problem with using reliability based probabilistic design is the absence of simple computational approaches that can be easily implemented. MonteCarlosimulationsarecommonly usedto solvesoil structureinteraction problems. For a large and complex soil-structure interaction problem, it is computationally intensive to complete even a single run. This practical disadvantage can be solved only by a computationally efficient method. A special purpose application to perform probabilistic analysis in PLAXIS 2D, called PROBANA has been recently developed at Plaxis B.V. PROBANA performs direct probabilistic calculations in the finite element framework, using First Order Reliability Method or Monte Carlo Method. In this thesis, PROBANA (FORM) is used to perform reliability analysis for three benchmarks, and the results from PROBANA – FORM are compared with Point Estimate Method (PEM) and other stochastic Methods. The results from FORM are found to be comparable with that of PEM. It is concludedthatPEMislessaccurateduetoassumptionsmadebyPEMintheunderlying output distribution and FORM is more accurate and practical as it is computationally less intensive compared to other stochastic methods such as the Monte Carlo analysis. An extensive comparison of the reliability based method with Eurocode design method shows possibilities to implement reliability methods with EC7. One such approach is proposed, and demonstrated with the benchmarks

A Low Distortion Reversible Data Hiding Technique Using Improved PPVO Predictor
No full textAbstractReversible data hiding is a technique that embeds additional information into some distortion-unacceptable cover media, such as military images, in a reversible manner so that the original cover image can be restored after extraction of the hidden information. This work extends a recently proposed reversible data hiding (RDH) scheme of Qu et al. which is based on pixel-based pixel- value-ordering(PPVO) and prediction-error expansion. In Qu et al.’s method, each pixel is predicted using its sorted context pixels. In this work, the pixel neighborhood of each pixel is expanded to optimize the embedding performance in terms of capacity- distortion behavior. This can better exploit image redundancy; achieve superior embedding performance and low distortion. Thus, the proposed method is able to embed adequate data into a cover image with limited distortion. The superiority of this predictor is verified through extensive experimental results. The proposed method outperforms prior works in terms of PSNR. The PSNR of a modified image versus its original one is guaranteed to be above 57.0dB

A Base-Sugar−Phosphate Three-Layer ONIOM Model for Cation Binding: Relative Binding Affinities of Alkali Metal Ions for Phosphate Anion in DNA
No full textA three-layer ONIOM approach was used to study the interactions of hydrated alkali metal ions such as Li+, Na+, and K+ with a DNA fragment containing two phosphate groups, three sugar units, and a G••C base pair modeled in the anion and dianion states. Among the three metal-binding combinations studied herein (outer-sphere, inner-sphere monodentate, and inner-sphere bidentate), the outer-sphere binding mode showed the highest binding energy (BE) for hydrated Li+ ions (103.1 kcal/mol) while the hydrated Na+ and K+ ions preferred the inner-sphere monodentate binding modes to the phosphate group of the anionic DNA fragment (BE = 87.9 and 98.2 kcal/mol for Na+ and K+, respectively). These data on the binding mechanisms of Li+, Na+, and K+ ions and the higher binding affinity of Li+ ions compared to Na+ and K+ ions in the anion model system of DNA are in good agreement with the previous experimental findings. On the other hand, in the dianion state, Li+ preferred inner-sphere monodentate, whereas Na+ and K+ ions preferred the outer-sphere structures. The neutral anion model ion revealed a more realistic picture of DNA−alkali metal ion interactions compared to the non-neutral dianion model systems
Governing Intellectual Property Rights Within Publicly Funded Biobanks
No full textGoverning Intellectual Property Rights Within Publicly Funded Biobanks addresses the implications that intellectual property rights (IPRs) have in the context of biobanks and how they need to be addressed in the governance of biobank-based research. The boom in biobanks and health databases as research infrastructures have evoked various legal and ethical debates. Since then numerous new developments have emerged such as digitalization, big-data research, and artificial intelligence that have important implications for biobank-based research and collaborations. This paradigm offers new legal challenges for commercial involvement, particularly within a publicly funded setting. In this innovative book, the author shows that securing maximum social benefit out of the knowledge emanating from the use of biobank resources lies in managing IP inputs and outputs effectively in keeping with the values that are core to such research
