Identification of the Genome Segments of Bluetongue Virus Type 26/Type 1 Reassortants Influencing Horizontal Transmission in a Mouse Model

Bluetongue virus serotypes 1 to 24 are transmitted primarily by infected Culicoides midges, in which they also replicate. However, “atypical” BTV serotypes (BTV-25, -26, -27 and -28) have recently been identified that do not infect and replicate in adult Culicoides, or a Culicoides derived cell line (KC cells). These atypical viruses are transmitted horizontally by direct contact between infected and susceptible hosts (primarily small ruminants) causing only mild clinical signs, although the exact transmission mechanisms involved have yet to be determined. We used reverse genetics to generate a strain of BTV-1 (BTV-1 RGC7) which is less virulent, infecting IFNAR(−/−) mice without killing them. Reassortant viruses were also engineered, using the BTV-1 RGC7 genetic backbone, containing individual genome segments derived from BTV-26. These reassortant viruses were used to explore the genetic control of horizontal transmission (HT) in the IFNAR(−/−) mouse model. Previous studies showed that genome segments 1, 2 and 3 restrict infection of Culicoides cells, along with a minor role for segment 7. The current study demonstrates that genome segments 2, 5 and 10 of BTV-26 (coding for proteins VP2, NS1 and NS3/NS3a/NS5, respectively) are individually sufficient to promote HT.
Rapid Product Development Metrics

A famous executive once said that “God is entitled to opinion, all others must bring facts and data”. To get agreement on the specific needs of a company, the best approach is to back up recommendations with facts. Are the new products which arrive in your manufacturing operation up to standard? Would a series of analytical tools and approaches which are being used in industry to improve and speed up new product development processes be useful? The “staffing ratios” tool is applied to make sure that the right amount of human resources and skills are in the right places at the right times. Does your company hit the planned market release dates for new products? Tools such as “time‐to‐market prediction” may be applied to assess past project performance and to predict the schedule outcome of current project‐in‐process. Does your company achieve early cross‐functional involvement on projects? The “concurrency matrix” tool may be used to define cross‐functional requirements and quantify the degree of paralleli.
Application of Simultaneous and Sequential Transportation Network Equilibrium Models to Riyadh, Saudi Arabia

The approach used in practice to predict short-run transport equilibria involves a sequential process, often with four stages: trip generation, trip distribution, modal split, and traffic assignment. This approach has an inherent weakness—its prediction need not be internally consistent. This deficiency has motivated attempts to predict all four stages simultaneously. The (conventional) sequential and simultaneous models are compared by calibrating and applying both models to the urban transportation network of Riyadh, Saudi Arabia. The main finding is that the simultaneous model produces better traffic flow predictions than the prediction of the conventional sequential model. These predictions are much better for the heavy volume links that are the most important links in the prediction process.
Well-controlled, selectively under-etched Si/SiGe gates for RF and high performance CMOS

We propose a new process of selective lateral under-etching of bi-layered Si/SiGe gates, aimed at the formation of well-controlled notches. Weak Ge mole fraction (/spl les/30%) and moderate notch depth render the notch formation compatible with standard CMOS process, and prevent dispersions. The latter, in the case of a shallow notch (/spl les/25 nm) are even smaller than in reference Si-gate devices without a notch. Higher commutation speed, better transconductance and better SGE/DIBL immunity are demonstrated experimentally on notched gate devices.
A neural network controller for indirect field orientation control

This paper presents the design of a neural network controller for the stator current command in an indirect field oriented system. A particular three layer neural network structure is studied in some detail. This neural network controller has two outputs, stationary frame q and d axis current commands i/sub qs//sup s/ and i/sub ds//sup s/. The input to the neural network are synchronous frame q and d axis current commands, delayed stationary frame q and d axis terminal voltage, rotor speed and delayed values of these parameters. The neural network structure, training and input output selection are discussed. A computer simulation of the closed loop indirect field oriented system with the neural network controller is also presented to verify the feasibility of such a controller.
Importance of Preserving the Non-Use Value of the Cultural Heritage: Case Study of George Town, Penang World Heritage Site

This paper aims to focus on the attitude and responses of the stakeholders on the importance of preserving the non-use value of cultural heritage for George Town, Penang World Heritage Site (GPWHS) conservation. This research has examined the possibilities of several attitudes of the stakeholders in explaining the importance of preserving the non-use value for the GPWHS conservation. Pearson’s Correlation and Multiple Linear Regressions were used in predicting the dependent variable using a set of several independent variables. The purpose of the correlation test was to prove whether the correlation between the dimensions of the independent variables has had any influence on the non-use value of cultural heritage for the GPWHS conservation. A face-to-face interviewing technique using the structured CV questionnaire aided by photo images-supported was applied in this survey. The numbers of completed questionnaires were 294 from local residents and 147 from tourists (domestic and foreign) in GTWHS. This paper reveals that there was a relationship between the local stakeholders’ attitude and responses on the importance of preserving the non-use value and the WTP value for the GTWHS conservation.
“Messy Inclusion”: A Call for Dignity of Risk in Inclusive Postsecondary Education

As inclusive postsecondary education (IPSE) programs emerge and expand across the United States, many young people with intellectual and developmental disabilities (IDD) have access to higher education for the first time. To support growth and identity development, students with IDD should have access to all aspects of college life (e.g., activities, relationships, opportunities). Furthermore, students with IDD should have the freedom to take emotional, physical, and intellectual risks relative to those of their peers without disabilities. This leading edge article is written by practitioners and researchers with and without disabilities associated with the University of Missouri St. Louis IPSE program, Succeed. To center the voices of persons with disabilities, any direct quotations are in italics. In this article, we advocate for increased dignity of risk in IPSE, present a model to assess and make programmatic decisions regarding dignity of risk in IPSE, and highlight five philosophical values that guide our work toward “messy inclusion. ”
Reconfigurable nonvolatile Boolean logic with one-transistor-two-memristor for in-memory computing

In-memory computing is highly expected to break the von Neumann bottleneck and memory wall. Memristor with inherent nonvolatile property is considered to be a strong candidate to execute this new computing paradigm. In this work, we have presented a reconfigurable nonvolatile logic method based on one-transistor-two-memristor device structure, inhibiting the sneak path in the large-scale crossbar array. By merely adjusting the applied voltage signals, all 16 binary Boolean logic functions can be achieved in a single cell. More complex computing tasks including one-bit parallel full adder and set–reset latch have also been realized with optimization, showing simple operation process, high flexibility, and low computational complexity. The circuit verification based on cadence PSpice simulation is also provided, proving the feasibility of the proposed design. The work in this paper is intended to make progress in constructing architectures for in-memory computing paradigm.
A Reliable Energy Efficient Wireless Sensor Network Hierarchical Routing Algorithm

The existing clustering protocols exists shortages that the nodes with small residual energy may be choose as cluster nodes, which communicate directly with sink causes more energy consumption. Member nodes transmit data directly to cluster head also caused more energy consumption. A reliable energy efficient wireless sensor network hierarchical routing algorithm (REHRA) is proposed to further improve energy efficiency. It introduces residual energy factor for election of heads that makes nodes with more residual energy priority become heads. The data transmission for heads to sink uses flooding algorithm that ensures reliability. Routing tree is formed within local cluster and data delivers from leaf nodes to the cluster head. Performance analysis and simulation experiment shows that the new algorithm provides higher energy efficiency and longer lifetime.
Mapping the Antecedents of Telework Diffusion: Firm‐Level Evidence from Italy

Previous literature has studied telework practices predominantly from the employees' perspective rather than exploring its use at the firm level. With the objective of contributing to reducing this research gap, the relationship between firms' adoption of telework and the firms' technological, organisational and environmental contexts is explored. Data were obtained from a survey conducted between 2005 and 2009 on a sample of 1,134 Italian firms in the Piedmont region. The results show an overall increase in the diffusion of telework primarily attributable to a rise in the adoption of ‘mobile’ work rather than home‐based forms of telework. The results also show that firms that had previously adopted information systems supporting core business processes and knowledge management were more inclined to adopt telework. Telework arrangements were more widely diffused among firms facing a growing and geographically dispersed market demand, and also in the contexts of higher levels of human capital and lower capital intensity.
Stability issues of sequence adaptation for CDMA systems with antenna arrays

The sequence adaptation problem for code division multiple access (CDMA) systems with antenna arrays is considered. The problem can be formulated as a sequence adaptation game. Each user would like to choose a signature sequence that minimises his/her interference based on an interference measure. It is well known that, with arbitrary interference measures, sequence adaptation in antenna array systems may not have an equilibrium point (Nash equilibrium). The authors prove that additivity, continuity and symmetry of the interference measures are three sufficient conditions for this existence. Adaptive algorithms are also developed for sequence adaptation in antenna array systems. Simulations show that sequence adaptation with antenna arrays can significantly improve the system throughput over the existing system with antenna arrays.
Performance Prediction and Demonstration of a Miniature Horizontal Axis Wind Turbine

A miniature wind turbine (MWT) has received great attention recently for powering low-power devices. In this paper, a physics-based comprehensive model for predicting the performance of a miniature horizontal axis wind turbine (MHAWT) was established. The turbine rotor performance was investigated and an approximation of the power coefficient of the turbine rotor was made. Incorporation of the approximation with the equivalent circuit model, which was proposed in accordance with the principles of the MHAWT, in addition to its overall system performance versus the resistive load and ambient wind speed, was predicted. To demonstrate predictive modeling capability, the MHAWT system comprised of commercially available off-the-shelf components was designed and its performance was experimentally tested. The results matched well with those by prediction modeling, which implies that the proposed model holds promise in estimating and optimizing the performance of the MWT.
A Numerical Study on the Performance Improvement of Guide Vanes in an Axial-flow Pump

ABSTRACT This paper presents a numerical study on the performance improvement of axial-flow pump with guide vanes. Design optimization for guide vanes in an axial-flow pump has been studied through the implementation of a commercial CFD code and DOE (design of experiments). We also discussed how to improve the performance of the axial-flow pump by designing the guide vanes. Geometric design variables were defined by the meridional plane and vane plane development of guide vanes. The effect of hub tip ratio analyzed the meridional plane of guide vanes. The importance of the geometric design variables was analyzed using 2 k factorial designs. The objective functions for guide vane geometric variables were defined as the total efficiency and the total head at the design flow rate. From the 2 k factorial design results, the important design variables were found and the performance was increased in comparison with the base design model. † 1. 서 론 축류펌프는 저양정으로 대용량의 유체를 이송하는 터보형 펌프로 비속도가 높으며, 회전체인 임펠러(impeller)와 고정되어 있는 안내깃(guide vane)으로 구성되어 있다. 안내깃은 임펠러를 통과한 유체의 회전운동에너지를 압력에너지로 회복시켜 주는 역할을 하고 있다. 안내깃의 형태는 임펠러 후단에서 나오는 유체의 회전속도성분을 줄일 수 있도록 설계한다. 최근 펌프의 설계 기술 발달로 인해서 축류펌프의 성능 향상을 위한 연구는 실험적으로, 수치적으로 활발히 이루어지고 있다. 특히 컴퓨터의 성능 발달과 더불어 전산유체역학(CFD)을 이용한 수치해석을 통하여 축류펌프의 임펠러와 안내깃의 유동장을 분석하고, 펌프 성능을 높이는 연구가 이루어지고 있다. 김성 등

Adoption of Project Management Methodology and Challenges Faced: A Comparative Analysis between Government IT Sector and IT Organisations in the Corporate Sector in Kerala

Adoption of a Project Management methodology is highly critical in the success of projects in any domain. It is imperative that a matured project management methodology is significant in the successful implementation of projects. Various Project management methodologies such as PMBOK, Waterfall, PRINCE2, Agile, etc. are followed in different domains including IT. Yet challenges remain and very few projects are able to adopt these methodologies for project success. This paper covers a comparative analysis between corporate IT organisations operating in Kerala and IT organisations owned by Government of Kerala. The paper aims to identify the project management methodology, the level of project management practices, the reasons for project failures and the challenges in the adoption of a Project management framework. The study was conducted among 50 employees of four IT organisations in Government sector and 50 employees of Corporate IT sector in the state of Kerala, India. The focus is to understand the differences in project management practices, specific challenges in adoption of Project Management methodology between Government IT sector and Corporate IT organizations in Kerala. This study aims to enhance in the current practices of project management to create more successful projects in IT domain in Government Sector.
Efficacy of coverage radius-based power control scheme for interference mitigation in femtocells

A novel coverage radius-based downlink power control scheme to mitigate interference in densely deployed femtocells is presented. A femtocell access point (FAP) self-update algorithm is implemented, which determines the coverage radius of the femtocell with respect to its farthest served femtocell user equipment (FUE). Based on varying coverage radii, a max/min function is used to adjust the downlink transmit power value of a FAP. System-level simulations are performed to compare the performance of the presented scheme with the existing fixed coverage radius schemes. Even though the proposed scheme results in better cross-tier signal to interference plus noise ratio (SINR) values, due to a low co-tier SINR it is found that the efficacy of adaptive power control schemes based on the pilot power of a FAP is less significant if FUEs are located close to the neighbouring FAPs in densely deployed urban femtocells.
Of PhDs, Pirates, and the Public: Three-Dimensional Printing Technology and the Arts

The confluence of three-dimensional printing, three-dimensional scanning, and the internet will explode the dividing line between the physical and the digital worlds and will bring millions of lay people into intimate contact with the full spectrum of intellectual property laws. One of the areas most affected by 3D printers will be three-dimensional art. This Article analyzes several ways in which 3D printing technology will affect the creation, delivery, and consumption of art. Not only does 3D printing offer great promise for creative works, but it also presents a problem of piracy that may accompany the digitization three-dimensional works. As 3D printing technology’s relationship to intellectual property law is largely unexplored, this Article explores foundational issues regarding how copyright law applies to 3D printing technology, laying the groundwork upon which further analysis of 3D printing’s effects on copyright law may be built.
Stereo‐imaging network design for precise and dense 3d reconstruction

This paper presents a novel stereo‐imaging network design strategy comprising four steps: datum definition, optimum distance estimation, candidate camera position generation, and lastly clustering and selection of vantage viewpoints. An approximate 3D mesh model of an object from a quick low‐cost system is used in the first step of the method. An ellipsoid is fitted to the rough model in order to find a suitable imaging distance regarding range‐ and visibility‐related constraints for a stereopair. Next, a set of viewpoints is provided taking into account the ellipsoid and the calculated distance. Finally, camera positions and orientations are defined by clustering and choosing the vantage viewpoints. A system, called “imaging network designer” (IND), has been developed based on this method and is evaluated with two different tests. Results show that IND can provide an imaging network, which fulfils the expected precision for the entire object.
A three-phase predictive PWM AC/DC converter with phase compensation and space vector control

In this paper, a current-controlled three-phase PWM AC/DC power converter is described. The current control is based on the predictive and the space vector PWM scheme. The phase shift caused by the predictive current control is compensated adaptatively so that the predictive-controlled PWM AC/DC power converter can maintain its performance with unity power factor and fixed switching frequency at low sampling frequency. The control system is implemented by an 8-bit microcontroller. By using the space vector control, low ripples in the current and the voltage as well as fast dynamic responses are achieved with a small DC link capacitance employed. <<ETX>>

Re-Presenting Christian Tradition as a Source of Inspiration and Integration for Educators in Catholic Schools—A Proposal

A significant challenge facing leaders of Catholic schools in Ireland today is to ensure an appreciation for, and understanding of, the Catholic identity of the school among members of staff. A first aim of this research project was to create a ‘vital idea’ to re-present Christian faith to people working in Catholic schools, in a way that might resonate with the real world of teaching and learning and with their own lives. Drawing from Fratelli Tutti), we used the phrase ‘A Love that impels towards communion’ as the ‘vital idea’. A second aim was to present it to principals of second-level Catholic schools and garner their responses to it. We did this with twelve principals, using a focus group methodology. We first explained the thinking behind the ‘vital idea’, and then gathered their responses to it. The reaction of the principals was favourable. It made sense to them personally and chimed with much of what they are doing professionally. However, the word ‘communion’ was found not to be helpful. A further finding relates to values: while the values in the ‘vital idea’ were embraced and talked about easily, there was little explicit reference to God, the source of those values.
