Massive Data Processing and Management in Cloud Computing: A Survey

Cloud computing, "an old idea whose time has finally come" [1], has been gaining much interest from both IT industry and academia since it promises a cheaper and better way of computing by leasing their computing from the data centers of IT companies which are big enough to realize the economy of scale. In cloud computing, data processing is parallelized across tens of thousands of node computers which compose certain data centers. Although traditional distributed and parallel computing models such as parallel DBMS have already been discussed for many years, there are distinct differences between cloud computing and the conventional parallel processing. In addition, managing data in the cloud immensely differs from the conventional DBMS techniques in terms of the aggressive use of data replication for high performance and availability, less strong consistency model, simpler access patterns and the support of less-rigid data model. This paper gives readers a brief survey of techniques for processing and for managing data in cloud computing. Including the current techniques adopted in cloud computing, authors give guidelines about how to select relevant techniques with given work type and workload. Finally, we suggest research issues and opportunities in cloud data processing and management.
Synergistic Effect in Zinc Phthalocyanine—Nanoporous Gold Hybrid Materials for Enhanced Photocatalytic Oxidations

Nanoporous gold (npAu) supports were prepared as disks and powders by corrosion of Au-Ag alloys. The npAu materials have pore sizes in the range of 40 nm as shown by scanning electron microscopy (SEM). The surface was modified by a self-assembled monolayer (SAM) with an azidohexylthioate and then functionalized by a zinc (II) phthalocyanine (ZnPc) derivative using “click chemistry”. By atomic absorption spectroscopy (AAS) and inductively coupled plasma mass spectrometry (ICP-MS) the content of zinc was determined and the amount of immobilized ZnPc on npAu was calculated. Energy-dispersive X-ray (EDX) spectroscopy gave information about the spatial distribution of the ZnPc throughout the whole porous structure. NpAu and ZnPc are both absorbing light in the visible region, therefore, the heterogeneous hybrid systems were studied as photocatalysts for photooxidations using molecular oxygen. By irradiation of the hybrid system, singlet oxygen is formed, which was quantified using the photooxidation of 1,3-diphenylisobenzofuran (DPBF) as a selective singlet oxygen quencher. The illuminated surface area of the npAu-ZnPc hybrid system and the coverage of the ZnPc were optimized. The synergistic effect between the plasmon resonance of npAu and the photosensitizer ZnPc was shown by selective irradiation and excitation of only the phthalocyanine, the plasmon resonance of the npAu support and both absorption bands simultaneously, resulting in an enhanced photooxidation activity by nearly an order of magnitude.

Cloud Computing Perceived Importance in the Middle Eastern Firms: The Cases of Jordan, Saudi Arabia and United Arab Emirates from the Operational Level

Firms need cloud computing adoption for strategic and competitive goals, generating business value, and at last gaining competitive advantage. This study reviews the literature regarding cloud computing and IT governance, and presents a research model along with its hypotheses formulation to examine the factors impacting cloud computing perceived importance in several Arab firms, specifically Jordan, Saudi Arabia and United Arab Emirates by using the integration of Technology Acceptance Model (TAM) model and Technology-Organizational-Environmental (TOE) framework as adapted from [1]. 329 returned surveys from top, middle-level IT managers, and IT employees from the operational level of the studied firms were analyzed using the structural equation modeling technique. The study found relative advantage, compatibility, complexity, organizational readiness, top management commitment, and training and education as important variables for impacting cloud computing adoption using perceived ease of use and perceived usefulness as mediating variables. The model explained 61%, 63%, and 74% of cloud computing adoption for perceived usefulness, perceived ease of use and perceived importance respectively.

Physical properties of the thermoelectric cubic lanthanum chalcogenides La_{3-y}X_{4} (X=S, Se, Te) from first principles

We report ab initio calculations of the stability, lattice dynamics, and electronic and thermoelectric properties of cubic La3−yX4 (X=S, Se, Te) materials in view of analyzing their potential for thermoelectric applications. The lanthanum motions are strongly coupled to the tellurium motions in the telluride, whereas the motions of both types of atoms are decoupled in the sulﬁdes. Nevertheless, this has no impact on their thermal properties because experimentally all compounds have low thermal conductivity. We believe that this is due to umklapp scattering of the acoustical modes, notably by the low-energy optical modes at about 7-8 meV found in all three chalcogenides, as in cage compounds such as skutterudites or clathrates, even though there are no cages in the cubic Th3P4 structure. We ﬁnd that the energy band gap increases from the telluride to the sulﬁde, in good agreement with experiments. However, due to their similar band structure, we ﬁnd that all three compounds have almost identical thermoelectric properties. Our results agree qualitatively with experiments, especially in the case of the telluride for which a great amount of data exists. All our results indicate that the sulﬁdes have a strong potential for thermoelectricity and could replace tellurides if the charge-carrier concentration is optimized. Finally, we predict also a larger maximum ZT for the p-type doped materials than for the n-type doped ones, even though compounds with p doping have still to be synthesized. Thus our results indicate the possibility to make high-temperature performing thermogenerators based only on La3X4 compounds.
High-speed optical 3D sensing and its applications

Abstract This paper reviews high-speed optical 3D sensing technologies for obtaining the 3D shape of a target using a camera. The focusing speed is from 100 to 1000 fps, exceeding normal camera frame rates, which are typically 30 fps. In particular, contactless, active, and real-time systems are introduced. Also, three example applications of this type of sensing technology are introduced, including surface reconstruction from time-sequential depth images, high-speed 3D user interaction, and high-speed digital archiving.
Synthesis and Biological Effects of Acyclic Analogs of Deazapurine Nucleosides

Deaza analogs of three basic types of S-adenosyl-L-homocysteine hydrolase (SAHase) inhibitors, ( S )-DHPA ( I ), eritadenine ( II ) and AHPA ( III ), were prepared. Alkylation of 3-deazaadenine ( V ), 3-deazapurine ( VI ), 1-deazaadenine ( VII ) and 4-amino-6-bromo-5-cyanopyrrolo[2,3- d ]pyrimidine ( XXII ) with ( R )-2,2-dimethyl-4-tosyloxymethyl-1,3-dioxolane ( XIIIb ), followed by acid hydrolysis, afforded the corresponding ( S )-2,3-dihydroxypropyl derivatives XVIIa -XIXa and XXV . Reaction of V and VII with 2,3- O -cyclohexylidene-D-erythrono lactone ( XXIX ) and subsequent removal of the protecting groups in an acid medium gave eritadenine analogs XXVII and XXVIII . Compounds V and VII were alkylated with bromoacetaldehyde diethyl acetal to give N -(2,2-diethoxyethyl) derivatives XXXII and XXXIII from which the substituted acetaldehyde derivatives were liberated in situ and converted into compounds XXX and XXXI by cyanohydrine reaction followed by acid hydrolysis. The alkylations were performed in dimethylformamide with sodium or cesium salts of the bases. Biological activity was observed only with 3-deazaadenine derivatives XVIIa, XXVII and XXX , which exhibit both enzyme-inhibitory and antiviral activities.
Design of MAC Layer Resource Allocation Schemes for IEEE 802.11ax: Future Directions

ABSTRACT Wireless local area networks (WLANs) are widely deployed for internet-centric data applications. It is predicted that by 2018, about two-thirds of the world's internet traffic will be video, and more than half of the traffic will be offloaded to Wi-Fi networks. Consequently, WLANs need major improvements in both throughput and efficiency. New technologies continue to be introduced for WLAN applications for this purpose. The IEEE 802.11ac standard is the currently implemented amendment by the IEEE 802.11 standard working group that promises data rates at gigabits per second. The main features of the IEEE 802.11ac standard are adopting increased bandwidth and higher order modulation than the previous standard, and multiple-input multiple-output (MIMO) and multi-user MIMO transmission modes. These features are designed to improve the user experience. In addition to technologies that enhance the efficiency of the WLAN, the IEEE 802.11ax standard is also investigating and evaluating advanced wireless technologies to utilize the existing spectrum more efficiently. These modern communications technologies are steadily advancing physical layer data rates in WLANs, although data throughput efficiency of the WLAN may degrade rapidly as the physical layer data rate increases. The fundamental reason for the degradation is that the current medium access control (MAC) protocol allocates the entire channel to one user as a single source due to equally distributed time domain contention resolution. The challenges and difficulties have already been identified for designing efficient MAC layer resource allocation (MAC-RA) schemes for the upcoming IEEE 802.11ax high-efficiency WLAN. However, there is no profound investigation outcome for this kind of efficient resource allocation. Therefore, in this paper, we conduct an extensive survey of the expected features and challenges for IEEE 802.11ax in the design of fair and efficient MAC-RA. The associated previous research work is summarized as to future directions. Moreover, the need for each directed scheme is highlighted.
MiniSat v1.13 - A SAT Solver with Conflict-Clause Minimization

In this poster we summarize the features of the MiniSat version en- tering the SAT Competition 2005. The main new feature is a resolution based conflict clause minimization technique based on self-subsuming resolution. Ex- periments show that on industrial examples, it is not unusual for more than 30% of the literals in a conflict clause to be redundant. Removing these literals re- duces memory consumption and produce stronger clauses which may propagate under fewer decisions in the DPLL search procedure. We also want to raise attention to the particular version of VSIDS im- plemented in MiniSat, which we believe is a consistent improvement over the original VSIDS decision heuristic of the same magnitude as many of the recently proposed alternatives (GY02,Ry03).
Intelligent Calendar Applications: A Holistic Framework based on Ontologies

With the term ‘Intelligent Calendar Application’ we refer to traditional electronic calendars empowered with scheduling engines and rich information about events, in order to be able to automatically schedule the events in time and space. The additional event-related information that is necessary to automate the scheduling process includes temporal domain, duration range, feasible locations, constraints and preferences over the way the events are scheduled, etc. Asking the user to provide all this information for each event would render intelligent calendars less attractive compared to traditional calendars. In order to overcome this limitation, we have recently proposed the use of general ontologies to describe any kind of everyday human activity. In this article we extend our work in three ways: (a) by extending the general ontologies with domain ontologies, particularly, an ontology to describe activities related with participating in scientific conferences; (b) by integrating these ontologies within a deployed intelligent calendar application; and (c) by developing a module to automatically extract ontological activity descriptions from web pages of scientific conferences. In this way, we propose a holistic framework concerning the integration of ontologies within intelligent calendar applications, comprising information modelling, gathering and integration.
Morphology of Intestinal Goblet Cells of The Dromedary ( Camelus dromedarius )

Morphology of the goblet cells in the intestine of the dromedary ( Camelus dromedarius ) was carried out by light and electron microscopes. Histologically, the goblet cells appeared as globular or ovoidshaped with basally located flat nuclei. They were dispersed among the columnar cells lining the epithelia of the villi and crypts of Lieberkuhn, and they increased greatly in number towards the rectum. Goblet cells showed positive reaction to (PAS) stain. Ultrastructurally, the scanning electron microscopy showed villi with rough surface which displayed goblet cells and microvilli in the small intestine. In the large intestine, the surface of the mucosal fold was characteristically covered by goblet cells and epithelial cells. The ultrastructure of the goblet cells showed the cell membrane lacked microvilli and the cytoplasm contained numerous large spherical granules of mucin, rough endoplasmic reticulum and mitochondria. The nucleus containing eccentric nucleolus, chromatin and heterochromatin materials. Key words : dromedary, goblet cells, intestine, morphology
Formation of Anatase Porous Ceramics by Hydrothermal Hot-Pressing of Amorphous Titania Spheres.

Anatase porous ceramics were produced at low temperatures below 350°C by hydrothermal hot-pressing of amorphous titania consisting of spherical particles prepared by hydrolysis of titanium tetraethoxide. After fine anatase crystals were formed in the original amorphous spheres by hydrothermal hot-pressing, the spherical particles were deformed and the fine anatase crystals flowed into the interstices among the original spheres by compression from outside the autoclave to form a compact with homogeneous distribution of fine pores. The fine anatase crystals in the compacts were bonded together by dissolution and deposition to form a compact with high mechanical strength. The porous anatase ceramics with open pores were prepared by drying in air after removing water which had occupied the pores in the compacts during hydrothermal hot-pressing.
IRAMY Inverter Control for Solar Electric Vehicle

Received Nov 12, 2015 Revised Apr 15, 2016 Accepted May 16, 2016 Solar Electric Vehicles (SEV) are considered the future vehicles to solve the issues of air pollution, global warming, and the rapid decreases of the petroleum resources facing the current transportation technology. However, SEV are still facing important technical obstacles to overcome. They include batteries energy storage capacity, charging times, efficiency of the solar panels and electrical propulsion systems. Solving any of those problems and electric vehicles will compete-complement the internal combustion engines vehicles. In the present work, we propose an electrical propulsion system based on three phase induction motor in order to obtain the desired speed and torque with less power loss. Because of the need to lightweight nature, small volume, low cost, less maintenance and high efficiency system, a three phase squirrel cage induction motor (IM) is selected in the electrical propulsion system. The IM is fed from three phase inverter operated by a constant V/F control method and Space Vector Pulse Width Modulation (SVPWM) algorithm. The proposed control strategy has been implemented on the texas instruments TM320F2812 Digital Signal Processor (DSP) to generate SVPWM signal needed to trigger the gates of IGBT based inverter. The inverter used in this work is a three phase inverter IRAMY20UP60B type. The experimental results show the ability of the proposed control strategy to generate a three-phase sine wave signal with desired frequency. The proposed control strategy is experimented on a locally manufactured EV prototype. The results show that the EV prototype can be propelled to speed up to 60km/h under different road conditions.

Saliency-aware Image Quality Assessment

Currently, visual saliency detection has been discovered and widely applied in the field of computer vision and image processing. Recent works have shown that considering human visual system features in image quality assessment will improve the consistence between objective assessment results and subjective visual perception. So we propose saliency-aware image quality assessment through a universal method to combine saliency detection with image quality assessment metrics. Since there is no image dataset used for image quality assessment and saliency detection researches simultaneously, we create a new image database, called TID-2013S, which is inheriting from image quality assessment database TID-2013 and contains 25 manually labeled ground truth images. In this paper, we select 8 representative full reference image quality assessment metrics and 7 state-of-the-art saliency detection algorithms to validate the performance of our proposed method. Experiment results show that when using the appropriate parameter of mapping function, our saliency-aware approach achieves the best performance improvement by 5.41%. And for most of image quality assessment metrics, the MCA saliency detection algorithm works best.
Automated Discovery and Learning of Complex Movement Behaviors

Automated Discovery and Learning of Complex Movement Behaviors Igor Mordatch Chair of the Supervisory Committee: Associate Professor Emanuel Todorov Computer Science & Engineering In order to create useful physical robots, tell narratives in animated films and interactive games, or understand the underlying principles behind human movement, it is necessary to synthesize movement behaviors with the same wide variety, richness and complexity observed in humans and other animals. Moreover, these behaviors should be discovered automatically from only a few core principles, and not be a result of extensive manual engineering or merely a mimicking of demonstrations. In this thesis, I develop novel optimal control methods and apply large-scale neural network training to synthesize movement trajectories and interactive controllers that give rise to a range of behaviors such getting up from the ground, climbing, moving heavy objects, hand manipulation, acrobatics, and various cooperative actions involving multiple characters and their manipulation of the environment. Coupled with detailed models of human physiology, motions that match various kinematic and dynamic aspects of real human motion can be produced de novo, giving the predictive power to conduct virtual biomechanics experiments. The resulting movements are also used to successfully control a physical bipedal robot. The approach is fully automatic and does not require domain knowledge specific to each behavior, pre-existing examples or motion capture data. Although discovery and learning are computationally-expensive and rely on cloud and GPU computing, the interactive animation can run in real-time on any hardware once the controllers are learned.
Approximate Bayesian Computation Algorithms for Estimating Network Model Parameters

Studies on Approximate Bayesian Computation (ABC) replacing the intractable likelihood function in evaluation of the posterior distribution have been developed for several years. However, their field of application has to date essentially been limited to inference in population genetics. Here, we propose to extend this approach to estimating the structure of transmission networks of viruses in human populations. In particular, we are interested in estimating the transmission parameters under four very general network structures: random, Watts-Strogatz, Barabasi-Albert and an extension that incorporates aging. Estimation was evaluated under three approaches, based on ABC, ABC-Markov chain Monte Carlo (ABC-MCMC) and ABC-Sequential Monte Carlo (ABC-SMC) samplers. We show that ABC-SMC samplers outperform both ABC and ABC-MCMC, achieving high accuracy and low variance in simulations. This approach paves the way to estimating parameters of real transmission networks of transmissible diseases.
Solutions of Nonlinear Polyharmonic Equation with Periodic Potential

Quasi-periodic solutions of a nonlinear periodic polyharmonic equation in $\R^n$, $n>1$, are studied. It is proven that there is an extensive "non-resonant" set ${\mathcal G}\subset \R^n$ such that for every $\vec k\in \mathcal G$ there is a solution asymptotically close to a plane wave $Ae^{i\langle{ \vec{k}, \vec{x} }\rangle}$ as $|\vec k|\to \infty $.
A High Throughput Device for Clonogenic Assays and Radiobiology Research

The gold standard tool for conducting in vitro radiobiology research is the clonogenic assay. The assay measures a cell’s ability to survive a therapy and is widely used when studying the effects of radiation and radiation sensitizing drugs. The standard clonogenic assay is a time consuming and labour intensive protocol which produces a single measurement with little context to the behaviours of the cells. A system was developed to perform high throughput clonogenic assays using a robotic well plate irradiator and a robotic live cell imaging system. The high throughput system conducts automated multi dose radiation delivery to a single well plate and can monitor the growth of cells into colonies. The system was tested by conducting high throughput clonogenic assays of HCT116 and FaDu cells using 384 well plates. This thesis describes the algorithms and methods used to conduct automated high throughput clonogenic assay on a robotic platform.
