Nebu: A topology-aware deployment system for reliable virtualized multi-cluster environments

Petabytes of data are processed daily by distributed applications built upon Hadoop and MongoDB. A significant fraction of these applications use cloud infrastructure to cope with this vast amount of data. Commercial clouds use virtualized environments, but most distributed applications are designed around the idea that they run on physical hardware. When this is no longer the case, guarantees for an application’s reliability and performance no longer hold. To remedy this issue, we design a powerful and comprehensive system called Nebu. Nebu is able to provide information about the physical topology of the cloud to the distributed application and is capable of automated virtual machine and application deployment. Nebu performs these tasks without depending on any single distributed application or virtual machine manager. Instead, Nebu provides efficient APIs that make it easy to provide compatibility with many popular distributed applications and virtual machine managers. We develop Nebu as an open source project using modern software engineering practices. In particular, we use the agile development method Scrum in combination with the Kanban scheduling system. We apply iterative API design through the use of RAML and supporting UML diagrams. Because no effective methods for testing distributed applications have been developed, we use both unit testing and manual testing. We also apply automated regression testing through the use of continuous integration. Because there are no formal guidelines on how to validate distributed applications for the kind we investigate in this work, we develop Nebu and perform real-world experiments with multiple distributed applications using an enterprise multi-cluster infrastructure. These experiments show that Nebu enables applications to give guarantees about reliability without degrading their performance. To increase Nebu’s usability, we provide extensions that offer compatibility with the distributed applications Hadoop and MongoDB, and virtual machine manager VMware. Both the system and the extensions to the system are developed in an enterprise environment. This holds good promise that Nebu will be adopted by open-source communities, as well as the industry.
An Optimal Ant Colony Algorithm for Efficient VM Placement

The process of mapping virtual machines to physical machines is known as virtual machine placement. In cloud computing environment optimal placement plays an important role for the improvement in power efficiency and resource utilization. In this paper, we study the Ant Colony optimisation and Multi-Objective Genetic Algorithm for the virtual machine placement problem. We propose an algorithm that combines both multi-objective algorithm and ant colony optimization. We also have designed an architecture for the proposed system. The algorithms were tested using some instances from the literature.

Occupational Programming in a Day Hospital for Patients with Dementia

It is estimated that four million persons in the United States aged 65 or older are living with a dementing illness. Adult day care has evolved during the past decade as an important component of the continuum of long-term care offered to community-living people with dementia. So, too, in Sweden, day care has become an important care option for older people in the community. Little research has yet been done on the nature of the dementia day-care experience or on the meaning of activity in the day-care setting in either country. This ethnographic study of a day hospital in Stockholm, Sweden, provides powerful new insights into the meaning of activity in this care setting. One of the questions most frequently raised about qualitative research relates to its applicability, i.e., the ability to generalize from the findings in one study to other larger populations. Qualitative research traditionally uses small numbers of respondents, and questions about the representativeness of the interpretations are understandable. Most of us who do naturalistic inquiry rely on what Van Manen (1990) calls the "validating circle of inquiry" (p, 27). Interpretations of lived experiences are validated by other people's lived experiences, i.e., by the affirmation of the readers' or listeners' nodding heads that say to us,"Yes! You have it right! " But even with the support of nodding heads, doubts remain about transferability of interpretations in qualitative research. To possess both situational uniqueness and transferability seems like a contradiction in terms. Transferability of interpretations across cultures
Structural and mechanical analysis of a mouse model of massive bone allografts and the effect of systemic anabolic parathyroid hormone therapy for graft healing

The use of bone allografts for skeletal reconstructions is commonplace clinically, but they are known to have incomplete healing even years after implantation, fail to develop union, and ultimately fail due to unrepaired fatigue damage. Identifying patients at risk for bone graft failure remains an unmet clinical need. Additionally, developing new ways of enhancing bone healing are being devised, so there is need for quantitative evaluation of their efficacy. The goals of this dissertation were to evaluate the specific structural qualities that contribute to the mechanical properties of grafted bones in a critically-sized defect in the mouse femur, to generate a novel measure of graft-to-host union, and to evaluate parathyroid hormone (PTH), a systemic anabolic bone therapy, for its effect on bone graft healing. An alternative to bone allograft from a tissue bank is to harvest bone from one site within the patient and implant it into the skeletal defect site. This live bone transplant is known as an autograft. In the first part of this dissertation, the two standard options of bone grafting were evaluated over time to determine what structural and morphological differences yielded the best mechanical performance over time. Through this study a working toolset was created which could be used to for evaluate novel adjuvant treatments for bone graft healing. We compared processed bone allografts from donor mice which lack any intrinsic healing capacity,
Mechanisms of Antibiotic resistance in Salmonella typhi

Salmonella typhi is is a particular Salmonella serovar that causes typhoid fever, a major public health problem in developing countries (Qamar et al., 2014). Typhoid fever is a systemic disease, without therapy, the illness may last for three to four weeks and death rate ranges between 12% and 30%. Although the global burden of typhoid fever has reduced, emergence of multidrugresistant S.typhi (MDRST) is still a threat to public health.

Dual PIV systems for space-time correlations in hot jets

Digital Particle Image Velocimetry (DPIV) has developed into a production grade research tool, which is being used at NASA GRC to improve our understanding of the decay of turbulence in jet flows - a critical element for understanding the acoustic properties of the flow. Two independent DPIV systems were installed in the GRC Small Hot Jet Acoustic Rig (SHJAR), enabling correlations in time and space. The data reported here were collected at a Mach number of 0.9 and temperature ratios of 0.86 and 2.7. The DPIV systems were mounted on independent traverse systems to facilitate image acquisition over a range of time delays and spatial separations. The collected DPIV data illustrate the differences in first order flow properties of cold and hot jets. The velocity fields from the two DPIV systems were then cross-correlated to determine the degree of correlation remaining in the flow as the downstream convection distance was increased. Increasing the physical spacing and time delays between the DPIV system acquisitions provided velocity fields containing information on the decay of turbulence in the flow. The DPIV results show that there are significant differences in the mean axial velocity component and turbulent kinetic energy for cold and hot flows at the same Mach number. The data also illustrate the decay of turbulence along the jet axis as revealed by the cross-correlations of the phase delayed and spatially separated DPIV vector maps.
An Enhanced Multi-Layered Cryptosystem Based Secure and Authorized auditing deduplication Model in Cloud Storage System

— As the cloud computing technology develops during the recent days, outsourcing data to cloud service for storage becomes an attractive trend, which benefits in sparing efforts on heavy data maintenance and management. Nevertheless, since the outsourced cloud storage is not fully trustworthy, it raises security concerns on how to realize data deduplication in cloud while achieving integrity auditing. In this work, we study the problem of integrity auditing and secure deduplication on cloud data. Specifically, willing achieving both data integrity and deduplication in cloud, we propose two secure systems, namely SecCloud and SecCloud. SecCloud introduces an auditing entity with maintenance of a Map Reduce cloud, which helps clients generate data tags before uploading still audit the integrity of data having been stored in cloud. Compared with previous work, the computation by user in SecCloud is greatly reduced during the file uploading and auditing phases. SecCloud is designed motivated individually fact that customers always must encrypt their data before uploading, and enables integrity auditing and secure deduplication on encrypted data.
ObsPy: a bridge for seismology into the scientific Python ecosystem

The Python libraries NumPy and SciPy are extremely powerful tools for numerical processing and analysis well suited to a large variety of applications. We developed ObsPy (http://obspy.org), a Python library for seismology intended to facilitate the development of seismological software packages and workflows, to utilize these abilities and provide a bridge for seismology into the larger scientific Python ecosystem. Scientists in many domains who wish to convert their existing tools and applications to take advantage of a platform like the one Python provides are confronted with several hurdles such as special file formats, unknown terminology, and no suitable replacement for a non-trivial piece of software. We present an approach to implement a domain-specific time series library on top of the scientific NumPy stack. In so doing, we show a realization of an abstract internal representation of time series data permitting I/O support for a diverse collection of file formats. Then we detail the integration and repurposing of well established legacy codes, enabling them to be used in modern workflows composed in Python. Finally we present a case study on how to integrate research code into ObsPy, opening it to the broader community. While the implementations presented in this work are specific to seismology, many of the described concepts and abstractions are directly applicable to other sciences, especially to those with an emphasis on time series analysis.

A global measure of child health-related quality of life: reliability and validity of the Child Health and Illness Profile - Child Edition (CHIP-CE) global score

SUMMARY As the treatment of children with medical and psychiatric disorders becomes increasingly reliant on pharmacological agents, it has become critical to assess the overall effects of these interventions on the health and well being of the children. The Child Health and Illness Profile - Child Edition (CHIP-CE) is a validated health-related quality of life (HRQoL) measure with five core domains: Satisfaction, Comfort, Resilience, Risk Avoidance and Achievement. The domain scores are valuable for identifying the area(s) of HRQoL in which children are most affected by an illness and its treatment. For some purposes, however, it would be desirable to measure overall HRQoL, as no single domain score effectively describes the whole child. A global score encompassing all domains could provide such a measure of HRQoL and could be an efficient outcome for evaluating the overall effect of an intervention. This article presents the development and validation of a global score for the CHIP-CE based on parents' reports. The investigations demonstrated that the CHIP-CE global score is a reliable measure of children's HRQoL. Tests of validity supported the use of the CHIP-CE global score, indicating that it is an additional tool to monitor and evaluate the outcomes of interventions in groups of children.
Discrete Chaos − Part I: Theory

We propose a definition of discrete Lyapunov exponent for an arbitrary permutation of a finite lattice. For discrete-time dynamical systems, it measures the local (between neighboring points) average spreading of the system. We justify our definition by proving that, for large classes of chaotic maps, the corresponding discrete Lyapunov exponent approaches the largest Lyapunov exponent of a chaotic map when M → ∞, where M is the cardinality of the discrete phase space. In analogy with continuous systems, we say the system has discrete chaos if its discrete Lyapunov exponent tends to a positive number (or to ∞), when M →∞. We present several examples to illustrate the concepts being introduced.
A novel mode controllable hybrid valve pressure control method for soft robotic gripper

Compared with traditional rigid gripper with joint-linkage structure, novel soft robotic gripper gives rise to continuous concern for the advantages of no-damage grasping, convenient manufacture, easy control, and low cost. In this study, we design and built two kinds of soft robotic grippers with four fiber-reinforced soft actuators which are distributed in circular and rectangle shapes for single and twin contacts grasping. A novel hybrid valve pneumatic control scheme combining proportional and solenoid valves is proposed. Also, a mode controllable hybrid valve pressure control method is proposed to adjust internal pressure of soft robotic grippers to adapt to different grasping tasks. The experiment results verify that the performances of hybrid valve outperform those of individual proportional valve or solenoid valve in the aspects of response time and steady-state accuracy. The hybrid valve has wide range of pressure regulation, result in that the soft robotic grippers are qualified to grasp various objects with different shapes, sizes, and weights.
Musée Dapper: New Directions for a Postcolonial Museum

Suite a l'ouverture du nouveau musee Dapper a Paris, l'A. propose quelques reflexions a propos de l'orientation museologique du musee, situant notamment sa politique museale et de la representation dans le contexte socioculturel et ideologique de l'art africain en France et de la configuration museale des musees d'ethnographie parisiens. D'une part, l'adoption d'une mise en exposition qui s'eloigne des modes (coloniaux) de representation des musees d'ethnographie et qui s'apparente plutot a la museologie des galeries ou des musees d'art, et, d'autre part, l'integration de l'art contemporain et de la diaspora, ont pour efffet de brouiller les frontieres entre les arts premiers et les oeuvres modernes. Selon l'A. , la strategie museale du musee Dapper, repondant aux interrogations museologiques de Franz Fanon, peut contribuer a proteger les arts anciens et a renforcer la production artistique contemporaine
Stylometric Investigation of Dante's Divina Commedia by Means of Multivariate Data Analysis Techniques

We analyzed the three parts of Dante's Divina Commedia using word frequencies as style markers for statistical analysis. Partial least square discriminant analysis was used to provide separation among the cantos of the three parts of the Comedy, Inferno, Purgatorio and Paradiso; the statistical models were able to successfully discriminate the poetic tones used by Dante to characterize and diversify the three parts, demonstrating the existence of a particular stylistic substratum in each cantica of the Commedia.
Caregiver's Burden, Coping, and Psycho-Education in Indian Households with Single- and Multiple-Affected Members with Schizophrenia

There is considerable evidence that family psychoeducation combined with pharmacological intervention for patients with schizophrenia increases family understanding of the illness, reduces the familial burden of care, and improves patient outcomes. However, no studies have determined whether the burden of care is greater for those families with more than one ill member (multiplex) than for families with a single-affected individual (simplex), and whether psycho-educational programs should be adapted to meet the specific needs of multiplex families. This study was conducted at a tertiary care postgraduate teaching hospital in New Delhi, India. Caregivers in simplex [n = 50] and multiplex families [n = 30] were compared with regard to levels of burden, coping, and the impact of psycho-education on family functioning. All the caregiver participants attended eight bimonthly, psycho-educational intervention sessions. They were assessed on the Burden Assessment Schedule (BAS) and the Coping Check List (CCL) before and after psycho-education. Caregivers from the multiplex families reported significantly more burden on two domains of the BAS, but there were no significant differences between the groups with regard to coping on the CCL. Following psycho-education, significant improvement occurred in the majority of domains of the BAS and the CCL; the effect sizes varied by domain and family type. Multiplex families face a greater burden of care compared with simplex families. Currently, available psycho-education programs are moderately effective for such families.
Communication Visualization – An Aid to Military Command and Control Evaluation

Communication in military command and control, C2, is essential to propagate information among military units. Evaluations of C2 can focus on different parts, e.g. computer support systems or tactical methods. Independent of focus, information of communication must be considered, thus design of visualization methods for handling communication data is necessary. Our approach is based on link analysis and considers general aspects of communication, specific aspects of military communication and visualization techniques. The report extends previous designs of communication timelines and communication graphs, which make it possible to analyze communication both in detail, and over large periods of time. Implemented visualization modules add aspects of link analysis to an existing framework and are tested with data from field exercises.
