A Closed Form Solution for Hydrodynamic Pressure of Gravity Dams Reservoir with Effect of Viscosity under Dynamic Loading

Hydrodynamic pressures acting on upstream of concrete dams during an earthquake are an important factor in designing and assessing the safety of these structures in Earthquake regions. Due to inherent complexities, assessing exact hydrodynamic pressure is only feasible for problems with simple geometry. In this research, the governing equation of concrete gravity dam reservoirs with effect of fluid viscosity in frequency domain is solved and then compared with that in which viscosity is assumed zero. The results show that viscosity influences the reservoir’s natural frequency. In excitation frequencies near the reservoir's natural frequencies, hydrodynamic pressure has a considerable difference in compare to the results of non-viscose fluid. Keywords—Closed form solution, Concrete dams reservoir, viscosity, Dynamic loads, Hydrodynamic pressure.
Power Consumption of Virtual Machine Live Migration in Clouds

Virtualization Technology has been employed increasingly widely in modern data centers in order to improve its energy efficiency. In particular, the capability of virtual machine(VM) migration brings multiple benefits for such as resources(CPU, memory, et al.) distribution, energy aware consolidation. However, the migration of virtual machines itself brings extra power consumption. For this reason, a better understanding of its effect on system power consumption is highly desirable. In this paper, we present a power consumption evaluation on the effects of live migration of VMs. Results show that the power overhead of migration is much less in the scenario of employing the strategy of consolidation than the regular deployment without using consolidation. Our results are based on the typical physical server, the power of which is linear model of CPU utilization percentage.
On the Goal Domain in the RM-ODP Enterprise Language: An Initial Appraisal Based on a Foundational Ontology

The “goal domain” addresses objectives in a broad scope ranging from high-level statements expressing the vision and mission of an organization (or community) to declarations of the results that must be achieved by business process execution. This paper reviews the support for the goal domain in ISO RM-ODP. We analyze the conceptualization for goals (objectives) in the reference model’s Enterprise Viewpoint using a fragment of the Unified Foundational Ontology (UFO) that deals with some aspects of social reality and intentionality. The interpretation of the RM-ODP concepts in terms of this foundation may help to provide a sound underpinning for these concepts and support the identification of possible extensions of the reference model.
High-Performance Poly-Si Vertical Nanowire Thin-Film Transistor and the Inverter Demonstration

In this letter, gate-all-around vertical nanowire (NW) polycrystalline silicon (poly-Si) thin-film transistors (TFTs) are demonstrated using a CMOS-compatible process. Both Nand P-TFT devices (with gate length down to 100 nm and a wire diameter of ~30 nm) exhibit good transistor performance, e.g., high Ion/Ioff ratio of >; 106, low subthreshold slope (SS ~ 100 mV/dec), and reasonable drain-induced barrier lowering [(DIBL); ~50 mV/V] with a wire diameter of ~30 nm. Inverters have been successfully fabricated based on the poly-Si NW TFTs, exhibiting well-behaved transfer characteristics.
Attitudes towards mentally ill in Montenegro: The Montenegrin version of CAMI

Introduction: Data about the general public' s attitude towards people with serious mental illness in Montenegro are scarce. A possible reason for this situation may lie in the fact that local researchers, in contrast to researchers elsewhere, have not at their disposal reliable instruments that could measure attitudes toward mentally ill people. Building on Taylor & Dear's development of the Community Attitudes towards Mental Illness scale (CAMI) we present a modified version of CAMI. Objective: The aim of this study was to examine the properties of the scale, to describe the dimensions of attitudes toward the mentally ill, and to identify demographic correlates of these dimensions. Method: Two hundred and eighty seven adults aged 17 years and above (range 17 to 84) completed the Montenegrin version of Community Attitudes toward the Mentally Ill. Their answers were analyzed by principal component analysis. Impact of contact with mentally disturbed person, age, education, and gender on attitudes towards mentally ill was assessed by stepwise regression analysis. Results: Principal component analysis with Varimax rotation revealed five components which account for 43 % of the total variance: 1) Respect for the human rights of patients and rejection of their stigmatization, 2) Distance towards the mentally ill, 3) Positive attitude towards the idea of psychiatry in the community, 4) Tolerance and sympathetic attitude towards mentally ill, and 5) Authoritarian attitude. The coefficient of internal consistency (Cronbach's alpha) of CAMI was 0.87. Gender (female) and prolonged contact with the mentally ill were associated with a more favourable attitude towards the mentally ill, but, unexpectedly, education level was weak predictor of positive attitude. Conclusion: There is a correspondence between the Montenegrin version and the original version of the CAMI. Further research should test replicability of the CAMI factor-structure, and focus on the impact of collectivist values on attitudes towards the mentally ill.
Actively Measuring Personal Cloud Storage

The Personal Cloud model is a mainstream service that meets the growing demand of millions of users for reliable off-site storage. However, despite their broad adoption, very little is known about the quality of service (QoS) of Personal Clouds. In this paper, we present a measurement study of three major Personal Clouds: DropBox, Box and SugarSync. Actively accessing to free accounts through their REST APIs, we analyzed important aspects to characterize their QoS, such as transfer speed, variability and failure rate. Our measurement, conducted during two months, is the first to deeply analyze many facets of these popular services and reveals new insights, such as important performance differences among providers, the existence of transfer speed daily patterns or sudden service breakdowns. We believe that the present analysis of Personal Clouds is of interest to researchers and developers with diverse concerns about Cloud storage, since our observations can help them to understand and characterize the nature of these services.
A comparative study of simulated augmented reality displays for vehicle navigation

In this paper we report on a user study in a simulated environment that compares three types of Augmented Reality (AR) displays for assisting with car navigation: Heads Up Display (HUD), Head Mounted Display (HMD) and Heads Down Display (HDD). The virtual cues shown on each of the interface were the same, but there was a significant difference in driver behaviour and preference between interfaces. Overall, users performed better and preferred the HUD over the HDD, and the HMD was ranked lowest. These results have implications for people wanting to use AR cues for car navigation.
Evaluation of interconnect fabrics for an embedded MPSoC in 28 nm FD-SOI

Embedded many-core architectures contain dozens to hundreds of CPU cores that are connected via a highly scalable NoC interconnect. Our Multiprocessor-System-on-Chip CoreVA-MPSoC combines the advantages of tightly coupled bus-based communication with the scalability of NoC approaches by adding a CPU cluster as an additional level of hierarchy. In this work, we analyze different cluster interconnect implementations with 8 to 32 CPUs and compare them in terms of resource requirements and performance to hierarchical NoCs approaches. Using 28 nm FD-SOI technology the area requirement for 32 CPUs and AXI crossbar is 5.59 mm2 including 23.61% for the interconnect at a clock frequency of 830 MHz. In comparison, a hierarchical MPSoC with 4 CPU cluster and 8 CPUs in each cluster requires only 4.83 mm2 including 11.61% for the interconnect. To evaluate the performance, we use a compiler for streaming applications to map programs to the different MPSoC configurations. We use this approach for a design-space exploration to find the most efficient architecture and partitioning for an application.
REVIEWING TRANSFERABILITY IN ECONOMIC EVALUATIONS ORIGINATING FROM EASTERN EUROPE

Objectives: The aim of this study is to analyze the quality and transferability issues reported in published peer-reviewed English-language economic evaluations based in healthcare settings of the Central and Eastern European (CEE) and former Soviet countries. Methods: A systematic search of economic evaluations of healthcare interventions was performed for Armenia, Azerbaijan, Belarus, Bulgaria, Estonia, Georgia, Turkmenistan, Kazakhstan, Lithuania, the former Yugoslav Republic of Macedonia, Republic of Moldova, Romania, the Russian Federation, Serbia, Slovenia, and Ukraine. The included studies were assessed according to their characteristics, quality (using Drummond's checklist), use of local data, and the transferability of inputs and results, if addressed. Results: Most of the thirty-four economic evaluations identified were conducted from a healthcare or payer perspective (74 percent), with 47 percent of studies focusing on infectious diseases. The least frequently and transparently addressed parameters were the items’ stated perspectives, relevant costs included, accurately measured costs in appropriate units, outcomes and costs credibly valued, and uncertainties addressed. Local data were often used to assess unit costs, baseline risk, and resource usage, while jurisdiction-specific utilities were included in only one study. Only 32 percent of relevant studies discussed the limitations of using foreign data, and 36 percent of studies discussed the transferability of their own study results to other jurisdictions. Conclusions: Transferability of the results is not sufficiently discussed in published economic evaluations. To simplify the transferability of studies to other jurisdictions, the following should be comprehensively addressed: uncertainty, impact of influential parameters, and data transferability. The transparency of reporting should be improved.
Evolution of Unit Fraction Conceptions in Two Fifth-Graders with a Learning Disability: An Exploratory Study

ABSTRACT The literature seems limited in what is known about conceptual processes that underlie evolution of students with learning disabilities (SLD) conceptions of fractions. This exploratory study examines how a foundational scheme of unit fractions (1/n) may evolve through the mathematical activity of two fifth grade girls. We analyze data segments from episodes conducted during a teaching experiment grounded in the activity of iterating estimates of one person's equal share. Our findings include four distinct conceptual stages: (1) No Conception of the Nature of Adjustment to the Magnitude of a Unit Fraction, (2) Evolving Anticipation of the Nature of Adjustment but not of its Relative Amount, (3) Anticipation of the Nature of Adjustment with an Evolving Partial Amount, and (4) a Dual Anticipation of the Nature and Amount of Adjustment. Findings demonstrate each girl was able to use her constructed scheme to successfully solve and reason about novel problems. We discuss the need for more research to confirm the findings from this study, while offering a conjecture of the possibilities for more SLDs to advance their conceptions of fractions in future interventions.
Bacterin That Induces Anti-OspA and Anti-OspC Borreliacidal Antibodies Provides a High Level of Protection against Canine Lyme Disease

ABSTRACT Groups of 15 laboratory-bred beagles were vaccinated and boosted with either a placebo or adjuvanted bivalent bacterin comprised of a traditional Borrelia burgdorferi strain and a unique ospA- and ospB-negative B. burgdorferi strain that expressed high levels of OspC and then challenged with B. burgdorferi-infected Ixodes scapularis ticks. The vaccinated dogs produced high titers of anti-OspA and anti-OspC borreliacidal antibodies, including borreliacidal antibodies specific for an epitope within the last seven amino acids at the OspC carboxy terminus (termed OspC7) that was conserved among pathogenic Borrelia genospecies. In addition, spirochetes were eliminated from the infected ticks that fed on the bacterin recipients, B. burgdorferi was not isolated from the skin or joints, and antibody responses associated specifically with canine infection with B. burgdorferi were not produced. In contrast, B. burgdorferi was recovered from engorged ticks that fed on 13 (87%) placebo-vaccinated dogs (P < 0.0001), skin biopsy specimens from 14 (93%) dogs (P < 0.0001), and joint tissue specimens from 8 (53%) dogs (P = 0.0022). In addition, 14 (93%) dogs developed specific antibody responses against B. burgdorferi proteins, including 11 (73%) with C6 peptide antibodies (P < 0.0001). Moreover, 10 (67%) dogs developed Lyme disease-associated joint abnormalities (P < 0.0001), including 4 (27%) dogs that developed joint stiffness or lameness and 6 (40%) that developed chronic joint inflammation (synovitis). The results therefore confirmed that the bacterin provided a high level of protection against Lyme disease shortly after immunization.
Nobody's children: an exploration into a sense of belonging of adults who experienced institutional out-of-home care as children

In 2004 a Senate Community Affairs Reference Committee published a report that described the harsh conditions of institutional out-of-home care up to 1974, experienced by an estimated 500,000 Australian children, also known as ‘Forgotten Australians’. Because of issues of abuse and neglect, the Commonwealth Government identified this cohort on November 16, 2009 as a vulnerable group with ‘special needs’ in their senior years. A review of the literature exposed significant gaps in what is known about the Forgotten Australians. One of these gaps is a lack of discussion on a sense of belonging and its effects in later life. The aim of this study was to explore how individuals who lived in institutional out-of-home child care in Australia before 1974 experienced, during adult years, a sense of belonging in relationships with significant others, and in relation to community and a sense of self. Using hermeneutical phenomenology, this research was designed to explore participants’ narrated experiences by drawing on theoretical and methodological approaches that facilitate the expression of subjective experiences. Research methods included semi-structured interviews conducted with 21 participants in all states and territories of Australia between January 2012 and April 2012. Key findings included experiences of stigma and shame as well as not feeling part of, or belonging to communities or societal groups. For many, a sense of not belonging has impacted on how they see themselves in relation to community and others in later life. Several participants spoke of having stable places to live; however they also spoke of feelings of discomfort and of being disconnected from the communities in which they resided. The conclusion of this research was that most participants belonged to one of two distinct orientations. In the first group, members continued to have challenges with how they viewed themselves and connected to community. The second group contained those who have overcome the negative view of their sense of self; even though they continued to have challenges connecting to community. Finally, there was one outlier who never felt that his experiences in institutional care affected the way he viewed himself or how he connected to community. The findings highlight the need for further research so that services and education programs can be developed to assist Forgotten Australians integrating into social networks as they age.
Cell Immune Synapses Is Controlled by Its Segregation of HLA-C from ICAM-1 at NK

NK cell activity is controlled by the integration of signals from numerous activating and inhibitory receptors at the immunological synapse (IS). However, the importance of segregation and patterning of proteins at the NK cell IS is unknown. In this study, we report that the level of expression of HLA-C on target cells determined its supramolecular organization and segregation from ICAM-1 at the NK cell IS, as well as its capacity to inhibit NK cell cytotoxicity. At YTS NK cell synapses formed with target cells expressing low levels of HLA-C (i.e., 10 4 /cell surface), a multifocal patterning of MHC class I protein predominated, whereas for higher levels of expression (10 5 /cell surface), clusters of HLA-C were more commonly homogeneous, ring-shaped, or containing multiple exclusions. This correlation of protein density with its patterning at the IS was independent of ATP- or actin-driven processes. Importantly, ICAM-1 and HLA-C segregated only at synapses involving target cells expressing high levels of MHC protein. For peripheral blood NK clones, there were speciﬁc thresholds in the level of target cell HLA-C needed to inhibit cytotoxicity and to cause segregation of HLA-C from ICAM-1 at the synapse. Thus, the synapse organization of HLA-C, determined by its level of expression, could directly inﬂuence NK cell inhibition, e.g., by regulating the proximity of activating and inhibitory receptors. For the ﬁrst time, this suggests an important function for the assembly of an inhibitory NK cell IS. More broadly, segregation of proteins at intercellular contacts could transmit information about protein expression levels between cells. The Journal of Immunology, 2006, 177: 6904–6910.
Optimal Control of a Dual Three-Level Inverter System for Medium-Voltage Drives

Actual developments in medium-voltage drives aim at increasing the power capability of the PWM inverter. Parallel connection of power semiconductor devices permits increasing the output current, while series connected devices increase the output voltage. In either case are additional means required for balancing the current or voltage stress of the devices. The three-level neutral-point clamped (NPC) inverter topology offers an inherent means to ensure dynamic voltage balancing of a maximum of two series connected devices. Higher operating voltages can be achieved by series connection of entire inverter topologies. Two circuit topologies are considered that behave as five-level units. Synchronous optimal pulsewidth modulation is applied for their control. This permits reducing the switching frequency to the 100-Hz region without sacrificing on harmonic distortion.
A 90nm Manchester Code Generator with CMOS Switches Running at 2.4GHz and 5GHz

A Manchester code generator designed at transistor level with NMOS switches is presented. This generator uses 26 transistors and has the same complexity as a standard D flip-flop. It is intended to be used in a complex optical communication system. The main benefit of this design is the use of a clock signal running at the same frequency as the data. Output changes on the rising edge and falling edge of the clock. The circuit has been designed in a 90 nm UMC CMOS technology to evaluate the efficiency of the proposed approach and experimental results show a correct behavior up to 5 Gbit/s data rate.
Bilingual Synonym Identification with Spelling Variations

This paper proposes a method for identifying synonymous relations in a bilingual lexicon, which is a set of translation-equivalent term pairs. We train a classifier for identifying those synonymous relations by using spelling variations as main clues. We compared two approaches: the direct identification of bilingual synonym pairs, and the merger of two monolingual synonyms. We showed that our approach achieves a high pair-wise precision and recall, and outperforms the baseline method.
L2 Interactional Competence as Increased Ability for Context-sensitive Conduct: A Longitudinal Study of Story-openings

This article sets out to investigate second language (L2) interactional competence and its development over time by zooming into a conversational activity that is pervasive in our social lives: storytelling. We present a longitudinal case study of a German L1 speaking au-pair’s conversational storytellings during her nine-month stay with a French-speaking host family. We document how her practices and resources for opening a story change over time: She increasingly uses techniques allowing her to secure recipiency, to project features of the nature of the incipient story, and to display its relation to preceding talk; and she shows increased use of grammatical constructions that are fitted for the task of getting these interactional jobs accomplished. The findings suggest that the development of L2 interactional competence centrally hinges on speakers’ increased ability to design talk in a way for it to be attended to and understood by others, and to deploy context-sensitive conduct based on both sequential and linguistic resources. While the study enhances our understanding of the nature and the development of L2 interactional competence, it also critically relates to current discussions regarding longitudinal comparative analysis of social practices.
Nonlinear Contractions and Semigroups in Complete Fuzzy Metric Spaces

AbstractOur main purpose in this paper is to introduce the notion of φ -contractive mapping in fuzzy metric spaces and to present two new re-sults on the existence and the approximation of ﬁxed point of nonlinearcontractions mappings and semigroups in fuzzy metric spaces. Theseresults are of interest in view of analogous results in metric spaces (seefor example [1], [7]) Mathematics Subject Classiﬁcation: Primary 47H10, 54H25Keywords: Fixed point, fuzzy metric, left reversible semigroup, nonlinearcontractive conditions 1 Introduction Our terminology and notation for fuzzy metric spaces conform of that Georgeet al. [5, 6]. Recently Gregori et al. [4] have showed that the study of theintuitionistic fuzzy metric space (IFMS) ( X,M,N,∗,♦ ) can be reduced to thestudy of the fuzzy metric space (FMS) ( X,M,∗ ). More exactly, the topology τ ( MN ) of an IFMS ( X,M,N,∗,♦ ) coincides with the topology τ ( M ) generatedby the FMS ( X,M,∗ ), which has as a base the family of open sets. So, ourstudy is limited to FMSs. Deﬁnition 1.1
The Use of Alternative Social Networking Sites in Higher Educational Settings: A Case Study of the E-Learning Benefits of Ning in Education

Distance education as a primary means of instruction is expanding significantly at the college and university level. Simultaneously, the growth of social networking sites (SNS) including Facebook, LinkedIn, and MySpace is also rising among today’s college students. An increasing number of higher education instructors are beginning to combine distance education delivery with SNSs. However, there is currently little research detailing the educational benefits associated with the use of SNSs. Non-commercial, education-based SNSs, such as Ning in Education, have been recently shown to build communities of practice and facilitate social presence for students enrolled in distance education courses. In order to evaluate the largely unexplored educational benefits of SNSs, we surveyed graduate students enrolled in distance education courses using Ning in Education, an education-based SNS, based on their attitudes toward SNSs as productive online tools for teaching and learning. The results of our study suggest that education-based SNSs can be used most effectively in distance education courses as a technological tool for improved online communications among students in higher distance education courses.
