IMPROVED SECURITY OF ATTRIBUTE BASED ENCRYPTION FOR SECURING SHARING OF PERSONAL HEALTH RECORDS

Cloud computing servers provides platform for users to remotely store data and share the data items to everyone. Personal health record(PHR)has emerged as a patient –centric model of health information exchange. Confidentiality of the shared data is the major problem when patients uses the commercial cloud servers because it can be view by everyone. , to assure the patient’s control over access to their own medical records; it is a promising method to encrypt the files before outsourcing and give access control to that data. Privacy exposure, scalability in key management, flexible access and efficient user revocation, have remained the most important challenges toward achieving fine-grained, cryptographically enforced data access control In this paper a high degree of patient privacy is guaranteed by exploiting multi-authority ABE. Divide the users in the PHR system into multiple security domains that greatly reduces the key management complexity for owners and users.

Broadening the applicability of FPGA-based soft vector processors

A soft vector processor (SVP) is an overlay on top of FPGAs that allows dataparallel algorithms to be written in software rather than hardware, and yet still achieve hardware-like performance. This ease of use comes at an area and speed penalty, however. Also, since the internal design of SVPs are based largely on custom CMOS vector processors, there is additional opportunity for FPGA-specific optimizations and enhancements. This thesis investigates and measures the effects of FPGA-specific changes to SVPs that improve performance, reduce area, and improve ease-of-use; thereby expanding their useful range of applications. First, we address applications needing only moderate performance such as audio filtering where SVPs need only a small number (one to four) of parallel ALUs. We make implementation and ISA design decisions around the goals of producing a compact SVP that effectively utilizes existing BRAMs and DSP Blocks. The resulting VENICE SVP has 2× better performance per logic block than previous designs. Next, we address performance issues with algorithms where some vector elements ‘exit early’ while others need additional processing. Simple vector predication causes all elements to exhibit ‘worst case’ performance. Density time masking (DTM) improves performance of such algorithms by skipping the completed elements when possible, but traditional implementations of DTM are coarse-grained and do not map well to the FPGA fabric. We introduce a BRAM-based implementation that achieves 3.2× higher performance over the base SVP with less than 5% area overhead. Finally, we identify a way to exploit the raw performance of the underlying FPGA fabric by attaching wide, deeply pipelined computational units to SVPs
Educational Theory Into Practice Software (ETIPS)

The ETIPS software is a Web-based learning environment that delivers cases that allow educators to practice instructional decision making. Here I recount its development but mainly emphasize the two key concepts that were central to our design process. The first was the Conceptual Assessment Framework, an evidentiary reasoning and design perspective that helped us to focus on which key attributes to build into the software and cases. The second concept is described as extreme programming, which is an iterative approach to software programming based upon user stories and rapid prototyping. The story of developing the ETIPS cases illustrates the need to know very clearly what the point is of the educational experience you are creating and to design software where form follows function. IntroductIon In this chapter, I recount the important aspects of the creation of the ETIPS software and its cases but mainly emphasize the two key concepts that were central to our design process. The first was the Conceptual Assessment Framework, developed by Mislevy, Steinberg, Almond, Haertel, and Penuel (2001); this framework helped us to focus on which key attributes to build into the software and cases. The second concept is described as extreme programming (Beck & Fowler, 2000), which is an iterative approach to software programming based upon user stories and rapid prototyping. The story of developing the ETIPS cases illustrates the need to know very clearly what the point is of the educational experience you are creating and to design software where form follows function.

Robotic Speech Recognition System

Speech recognition systems are the most natural means of communication with machines. Yet, the application of these systems in real robotic platforms is still not widespread due to several factors such as speed and accuracy of speech decoding. In this thesis, we addressed these factors from several perspectives and suggested a possible solution to each of them. There are three main objectives of this thesis. The first objective is to develop a simple speech decoder based on the recent advances in the field of speech recognition. This decoder is based on a static search space constructed using weighted finite-state transducers. The decoding mechanism is based on the Viterbi beam pruning and implemented using the token passing technique. To improve the speed of the developed decoder, we employed two approaches, namely likelihood caching and histogram pruning. As the developed decoder provides the primitive functions necessary for achieving real-time speech recognition, it can be viewed as a seed for future additions and improvements. In comparison with other speech decoders, such as Sphinx3 and HDecode, the developed decoder performs better when tested on the evaluation set of the Resource Management (RM1) speech corpus. The second objective is to improve the speech decoding accuracy. In this regard, two approaches have been proposed. The first approach is based on optimizing the language model parameters on transducer-based decoding graphs using sentence-level transition update. The decoding accuracy using the proposed method outperforms that of the common approach based on the word-pairs transition update, when tested on both TIMIT and RM1 speech corpora. In the second approach, a new framework is proposed for jointly optimizing the parameters of acoustic and language models on transducer-based decoding graphs. This framework exploits the inherent correlation between the acoustic and language models, and thus achieved better decoding accuracy when compared with separate optimization of the acoustic and language models. The third objective is to improve the command decoding accuracy. This objective is realized through proposing a new approach for extracting tiny decoding graphs corresponding to the potential spoken commands used in human-robot interaction. This approach is based on merging the traditional grammar rules with n-gram models to produce an elegant and tiny decoding graph suitable for single-pass decoding. This approach significantly improved the command decoding accuracy when compared with the traditional grammar and n-gram based approaches in benchmark testing of the command and control corpus, RM1. Additionally, a significant improvement in the decoding speed as well as a significant reduction in the required memory have been achieved, which emphasizes the effectiveness of the proposed approach for controlling service robots. iv
Fast algorithms for traversal of binary trees available for SoC

A mathematical corresponding relationship among a full binary tree,its sequential storage and its postorder-traversal storage are obtained by study of the node-indices of the binary tree.Based on the relationship,the algorithm is introduced that can fast convert a full binary tree and its sequential storage into its postorder-traversal storage,or vice versa.The algorithms can answer a query in constant time and perform a traversal in linear time.Being non-recursive and stack-free,having almost no branches or jumps and containing merely addition,subtraction,multiplication and bitwise operations,the algorithms are very concise and available for both conventional programming and professional developments such as systems-on-chip,embedded systems and so on.A guidance is presented for the algorithms to be used in design of mechatronic systems.

Analytical models for accelerating FPGA architecture development

Field-Programmable Gate Arrays (FPGAs) are widely used to i mplement logic without going through an expensive fabrication process. Current-generation FPG As still suffer from area and power overheads, making them unsuitable for mainstream adoption for large vo lume systems. FPGA companies constantly design new architectures to provide higher density, lower p ower consumption, and faster implementation. An experimental approach is typically followed for new arch itecture design, which is a very slow and computationally expensive process. This dissertation pre sents an alternate faster way for FPGA architecture design. We use analytical model based design techniques, where the m od ls consist of a set of equations that relate the effectiveness of FPGA architectures to the param eters describing these architectures. During early stage architecture investigation , FPGA architects and vendors can use our equations to quickl y short-list a limited number of architectures from a range of architectures under investigation. Only the short-listed architectures need then be investigated usin g an expensive experimental approach. This dissertation presents three contributions towards th e formulation of analytical models and the investigation of capabilities and limitations of these mod els. First, we develop models that relate key FPGA architectural parameters to the depth along the critical path and the post-placement wirelength. We detail how these models can be used to estimate the expected area of implementation and critical path delay for user-cir cuits mapped on FPGAs. Secondly, we develop a model that relates key parameters of t he FPGA routing fabric to the fabric’s routability, assuming that a modern one-step global/detai led router is used. We show that our model can capture the effects of the architectural parameters on rout ability. Thirdly, we investigate capabilities and limitations of an alytical models in answering design questions that are posed by the FPGA architects. Comparing with two exp erimental approaches, we demonstrate

Formal foundations for hybrid effect analysis

Type-and-effect systems are a powerful tool for program construction and verification. Type-andeffect systems are useful because it help reduce bugs in computer programs, enable compiler optimizations and provide program documentation. As software systems increasingly embrace dynamic features and complex modes of compilation, static effect systems have to reconcile over competing goals such as precision, soundness, modularity, and programmer productivity. In this thesis, we propose the idea of combining static and dynamic analysis for effect systems to improve precision and flexibility. We describe intensional effect polymorphism, a new foundation for effect systems that integrates static and dynamic effect checking. Our system allows the effect of polymorphic code to be intensionally inspected. It supports a highly precise notion of effect polymorphism through a lightweight notion of dynamic typing. When coupled with parametric polymorphism, the powerful system utilizes runtime information to enable precise effect reasoning, while at the same time retains strong type safety guarantees. The technical innovations of our design include a relational notion of effect checking, the use of bounded existential types to capture the subtle interactions between static typing and dynamic typing, and a differential alignment strategy to achieve efficiency in dynamic typing. We introduce the idea of first-class effects, where the computational effect of an expression can be programmatically reflected, passed around as values, and analyzed at run time. A broad range of designs “hard-coded" in existing effect-guided analyses can be supported through intuitive programming abstractions. The core technical development is a type system with a couple of features. Our type system provides static guarantees to application-specific effect management properties through refinement types, promoting “correct-by-design" effect-guided programming. Also, our type system computes not only the over-approximation of effects, but also their under-approximation. The duality unifies the common theme of permission vs. obligation in effect reasoning. Finally, we show the potential benefit of intensional effects by applying it to an event-driven system to obtain safe concurrency. The technical innovations of our system include a novel effect system to
RIBOSOME - mRNA INTERACTIONS THAT CONTRIBUTE TO RECOGNITION AND BINDING OF A 5’-TERMINAL AUG START CODON

RIBOSOME mRNA INTERACTIONS THAT CONTRIBUTE TO RECOGNITION AND BINDING OF A 5’-TERMINAL AUG START CODON by Karthik M. Krishnan Initiation is the rate-limiting step of translation and is an important regulatory step in gene expression. Translation initiation requires ribosome recognition of the mRNA’s start codon followed by formation of a stable ternary complex involving initiator tRNA. Several mRNA features are recognized and contacted by the ribosome, suggesting that the ribosome may possess multiple mRNA recognition features. Studies with leaderless mRNA have shown specific contacts between a leaderless mRNA’s 5’-AUG and several ribosomal proteins (r-proteins). We employed short-leadered mRNAs in order to further characterize the path of a leaderless mRNA’s 5’-AUG from initial association with the ribosome to its final placement at the ribosome’s decoding site (P-site). Our results suggest that Escherichia coli ribosomes can bind and inspect the 5’-terminus of all mRNAs for an AUG triplet, with close proximity of AUG to the 5’-terminus positively influencing ribosome binding and ternary initiation complex formation. Crosslinking studies showed that while 5’-AUG interactions with r-proteins S1, S3, S4, S7, S10 and S18 can occur in the absence of tRNA, movement of a 5’-AUG into the Psite requires tRNA. Addition of a nucleotide triplet upstream (i.e., a -1 triplet) to a leaderless mRNA’s start codon resulted in interference with 5’-AUG interactions with the r-proteins S3, S4, S7, S10 and S18 in a sequence-specific manner while allowing retention of these mRNAs on the ribosome. Investigation of Streptomyces lividans high salt-washed (HS) ribosomes and the features of leaderless aph mRNA that are important for ribosome binding further suggest that the recognition, binding and movement of an mRNA’s start codon into the ribosome’s P-site involves multiple contacts and interactions between r-proteins and the mRNA.

Performance-centric Bandwidth Allocation for Data Parallel Applications in Private Datacenters

In the context of private datacenters that are operated by Web service providers such as Google, multiple applications using data parallel frameworks, such as MapReduce, coexist and share a limited supply of link bandwidth capacities. In this thesis, we propose the notion of performance-centric fairness to guide bandwidth allocation among data parallel applications in private datacenters. With a tunable degree of relaxation on fairness, we design a distributed bandwidth allocation algorithm to arbitrate the tradeoff between fairness and utilization. We then conduct a deeper investigation of performance-centric bandwidth allocation with the presence of failures, and the flexibility of path selection, respectively. To minimize the adversing effect of failures, we propose an algorithm to jointly optimize bandwidth allocation and task placement. Also, by designing an applicationlevel scheduling algorithm that jointly optimize bandwidth allocation and path selection, we are able to improve application performance as well as bandwidth utilization.

Multiscale analysis of the CMB temperature derivatives

We study the Planck CMB temperature at different scales through its derivatives up to second order, which allows one to characterize the local shape and isotropy of the field. The problem of having an incomplete sky in the calculation and statistical characterization of the derivatives is addressed in the paper. The analysis confirms the existence of a low variance in the CMB at large scales, which is also noticeable in the derivatives. Moreover, deviations from the standard model in the gradient, curvature and the eccentricity tensor are studied in terms of extreme values on the data. As it is expected, the Cold Spot is detected as one of the most prominent peaks in terms of curvature, but additionally, when the information of the temperature and its Laplacian are combined, another feature with similar probability at the scale of 10̂ is also observed. However, the p-value of these two deviations increase above the 6% when they are referred to the variance calculated from the theoretical fiducial model, indicating that these deviations can be associated to the low variance anomaly. Finally, an estimator of the directional anisotropy for spinorial quantities is introduced, which is applied to the spinors derived from the field derivatives. An anisotropic direction whose probability is <1% is detected in the eccentricity tensor.
X-RAY OBSERVATIONS OF COMPLEX TEMPERATURE STRUCTURE IN THE COOL-CORE CLUSTER A85

X-ray observations were used to examine the complex temperature structure of A85, a cool-core galaxy cluster. Temperature features can provide evidence of merging events which shock heat the intracluster gas. Temperature maps were made from both Chandra and XMM-Newton observations. The combination of a new, long-exposure XMM observation and an improved temperature map binning technique produced the highest fidelity temperature maps of A85 to date. Hot regions were detected near the subclusters to the south and southwest in both the Chandra and XMM temperature maps. The presence of these structures implies A85 is not relaxed. The hot regions may indicate the presence of shocks. The Mach numbers were estimated to be ∼1.9 at the locations of the hot spots. Observational effects will tend to systematically reduce temperature jumps, so the measured Mach numbers are likely underestimated. Neither temperature map showed evidence for a shock in the vicinity of the presumed radio relic near the southwest subcluster. However, the presence of a weak shock cannot be ruled out. There was tension between the temperatures measured by the two instruments.
Two O2 If*/WN6 stars possibly ejected from the massive young Galactic cluster Westerlund 2

In this paper we report the identification of two new Galactic O2If*/WN6 stars (WR20aa and WR20c),ontheoutskirtsofthemassiveyoungstellarclusterWesterlund2.Themorphological similarity between the near-infrared spectra of the new stars with that of WR20a and WR21a (two of the most massive binaries known to date) is remarkable, indicating that probably they are also very massive stars. New optical spectroscopic observations of WR20aa suggest an intermediateO2If*/WN6spectraltype.Basedonamosaicmadefromthe3. 6µmSpitzerIRAC images of the region including part of the RCW49 complex, we studied the spatial location of the new emission line stars, finding that WR20aa and WR20c are well displaced from the centre of Westerlund 2, being placed at ≈36 pc (15.7 arcmin) and ≈58 pc (25.0 arcmin), respectively, for an assumed heliocentric distance of 8 kpc. Also, very remarkably, a radius vector connecting the two stars would intercept the Westerlund 2 cluster exactly at the place where its stellar density reaches a maximum. We consequently postulate a scenario in which WR20aa and WR20c had a common origin somewhere in the cluster core, being ejected from theirbirthplacebydynamicalinteractionwithsomeotherverymassiveobjects,perhapsduring some earlier stage of the cluster evolution.
