Improving the Efficiency of the Loop Method for the Simulation of Water Distribution Systems

AbstractEfficiency of hydraulic solvers for the simulation of flows and pressures in water distribution systems (WDSs) is very important, especially in the context of optimization and risk analysis problems, where the hydraulic simulation has to be repeated many times. Among the methods used for hydraulic solvers, the most prominent nowadays is the global gradient algorithm (GGA), based on a hybrid node-loop formulation. Previously, another method based just on loop flow equations was proposed, which presents the advantage that it leads to a system matrix that is in most cases much smaller than in the GGA method, but has also some disadvantages, mainly a less sparse system matrix and the fact that introducing some types of valves requires the redefinition of the set of network loops initially defined. The contribution of this paper is to present solutions for overcoming the mentioned disadvantages of the method based on loop flow equations. In particular, efficient procedures are shown for selecting the n.
Exploring influencing factors on rationality: A literature review of dynamic decision making studies in system dynamics

Simulators and experiments studying dynamic decision making offer a way of finding out about factors enforcing and inhibiting human rationality. This literature review of 51 studies from the system dynamics field helps to identify various factors that influence decision making. The factors are classified into model, simulator and player characteristics. In the paper the effect of these variables on gaming performance is reviewed and synthesized. Model characteristics such as presence of delay and increase of feedback strength seem to lower performance, while changes in exogenous conditions lead to mixed results. With regard to simulator characteristics, the decision interval does not seem to influence performance. Model transparency has a positive relation to performance, similar to decision information (in conjunction with player characteristics). Lastly, with regard to player characteristics, there is some evidence that a long-term goal increases performance. Although problem-solving style and mental model characteristics impact performance, no relation between general personality types and performance is found. Also, there are no consistent differences between individuals and pairs with regard to performance. The paper closes with brief comments on future research directions.

Time Distortion Anonymization for the Publication of Mobility Data with High Utility

An increasing amount of mobility data is being collected every day by different means, such as mobile applications or crowd-sensing campaigns. This data is sometimes published after the application of simple anonymization techniques (e.g., putting an identifier instead of the users' names), which might lead to severe threats to the privacy of the participating users. Literature contains more sophisticated anonymization techniques, often based on adding noise to the spatial data. However, these techniques either compromise the privacy if the added noise is too little or the utility of the data if the added noise is too strong. We investigate in this paper an alternative solution, which builds on time distortion instead of spatial distortion. Specifically, our contribution lies in (1) the introduction of the concept of time distortion to anonymize mobility datasets (2) Promesse, a protection mechanism implementing this concept (3) a practical study of Promesse compared to two representative spatial distortion mechanisms, namely Wait For Me, which enforces k-anonymity, and Geo-Indistinguishability, which enforces differential privacy. We evaluate our mechanism practically using three real-life datasets. Our results show that time distortion reduces the number of points of interest that can be retrieved by an adversary to under 3 %, while the introduced spatial error is almost null and the distortion introduced on the results of range queries is kept under 13 % on average.
Control plane issues in multilayer traffic engineering

Multilayer traffic engineering utilizes functionality in multiple network layers to optimize network performance and resource usage. For IP-over-optical networks in particular, automatic optical switching allows provisioning of on-demand lightpaths serving as capacity for IP/multiprotocol label switching (MPLS) links, allowing online reconfiguration of the IP/MPLS layer logical topology. Multilayer traffic engineering builds on the interaction between IP/MPLS routing and logical topology configuration. Technical issues in the IP/MPLS layer limit traffic measurement accuracy as well as routing flexibility and number of allowable topology updates. Through simulation, we examine the extent to which both measurement inaccuracies and routing granularity degrade multilayer traffic engineering performance.
New search algorithm for minimum redundancy linear arrays

An algorithm for finding minimum redundancy linear arrays (MRLAs) of longer lengths than previously possible is presented. The results obtained to date by this algorithm, which go beyond previously published results (length 68 arrays) are summarized. Included is a table of the number of MRLAs as a function of array length (up through length 90). In the process of making this table, errors in two references were discovered and corrected. Such information, along with the array patterns themselves, is extremely valuable in developing suboptimal searching techniques for still longer, but sparse, arrays. <<ETX>>
The Unicode Standard

The Unicode Standard is a global character set for worldwide computing covering the major modern scripts of the world as well as classical forms of Greek, Sanskrit, and Pali. The history and implications of Unicode Standard are discussed. The principles underpinning the design of the Unicode Standard are described with reference to those principles that also are present in USMARC and UNIMARC. Unicode give the potential to support every script. Expanding the character set would have consequences for transcription. Faithfulness of transcription has implications for retrieval. The addition of more characters to support more exact cataloging affects the economic cost of cataloging. The need for characters should be related not to the production of a surrogate for the physical item that has been cataloged, but to facilitating retrieval.
Synchronous Coordination of Distributed Components

This work contributes to the field of coordination, in particular to Reo, by improving existing approaches to execute synchronisation models in three major ways. First, this work supports decoupled execution and lightweight reconfiguration. We developed a prototype Dreams engine to test our distributed protocol, using an actor library for the Scala language. Reconfiguration of a small part of the system is independent of the execution or behaviour of unrelated parts of the same system. Second, Dreams outperforms previous Reo engines by using constraint satisfaction techniques. In each round of the execution of the Dreams framework, descriptions of the behaviour of all building blocks are combined and a coordination pattern for the current round is chosen using constraint satisfaction techniques. This approach requiring less time than previous attempts that collect all patterns before selecting one. Third, our work improves scalability by identifying synchronous regions. We statically discover regions of the coordination layer that can execute independently, thus achieving a truly decoupled execution of connectors. Consequently, the constraint problem representing the behaviour at each round is smaller and more easily solved.
Error Estimation in the Clenshaw-Curtis Quadrature Formula

Several error estimates for the Clenshaw-Curtis quadrature formula are compared. Amongst these is one which is not unrealistically large, but which is easy to compute and reliable when certain conditions are satisfied. The form of this new error estimate helps explain the considerable accuracy of the Clenshaw-Curtis method when the integrand is well behaved; in this case the method is nearly as accurate as Gaussian quadratures. It is argued that the Clenshaw-Curtis method is a better method for evaluating such integrals than either Romberg's process or Gaussian quadratures.
A Comparative Study to Examine the Socio-Economic Characteristics of Broadband Adopters and Non Adopters,

The aim of this study was to examine the socio-economic characteristics of broadband adopters and non-adopters in the UK. This study confirms the findings obtained from a previous study that examined the sociodemographic attributes of the household consumers of broadband technologies in local vicinity, the London Borough of Hillingdon. The findings of this survey support the view that the socio-economic characteristics such as age, gender, education, income and occupation have an imperative role in explaining the adoption of broadband in the household. A brief discussion on the implications and contributions is also provided in the conclusion of the paper.
Depth-image-based rendering (DIBR), compression, and transmission for a new approach on 3D-TV

This paper presents details of a system that allows for an evolutionary introduction of depth perception into the existing 2D digital TV framework. The work is part of the European Information Society Technologies (IST) project "Advanced Three-Dimensional Television System Technologies" (ATTEST), an activity, where industries, research centers and universities have joined forces to design a backwards-compatible, flexible and modular broadcast 3D-TV system. At the very heart of the described new concept is the generation and distribution of a novel data representation format, which consists of monoscopic color video and associated per-pixel depth information. From these data, one or more "virtual" views of a real-world scene can be synthesized in real-time at the receiver side (i.e. a 3D-TV set-top box) by means of so-called depth-image-based rendering (DIBR) techniques. This publication will provide: (1) a detailed description of the fundamentals of this new approach on 3D-TV; (2) a comparison with the classical approach of "stereoscopic" video; (3) a short introduction to DIBR techniques in general; (4) the development of a specific DIBR algorithm that can be used for the efficient generation of high-quality "virtual" stereoscopic views; (5) a number of implementation details that are specific to the current state of the development; (6) research on the backwards-compatible compression and transmission of 3D imagery using state-of-the-art MPEG (Moving Pictures Expert Group) tools.
Residual Fault Detection and Performance Analysis of G-O Software Growth Model

Quality assessment for the software growth models (SRGMs) is crucial is deciding the growth model for the application. The main goal of the growth model is to provide higher efficiency with optimal reliability. So there should be an analytical approach for the measurement of these factors. Here in this paper we propose one such exponential approach for the assessment of G-O (Goel, Okumoto) growth model under certain residual faults based on NHPP.
Analyzing Demographics: Assessing Library Use Across the Institution

In Fall 2011, staff at the University of Minnesota Libraries-Twin Cities undertook a project to measure how often, and in what ways, students used the Libraries’ services. Partnering with the University’s Office of Institutional Research, the team investigated ways to match library service usage to individual accounts while retaining patron privacy to determine who was – and was not – using the library. With complete data sets, the group was able to determine overall usage rates for undergraduate and graduate students and compare how students in different colleges used library services. This article discusses data gathering techniques, analysis, and initial findings.
Reading Skills and Reading Habits: A study of new Open University undergraduate reservees

A total of 365 potential Open University (OU) students responded to a postal test (via two cloze passages) of their reading skills, and a survey of their reading habits. A best-fit multiple regression model showed that previous educational level and time elapsed since a respondent had last finished a book were the best predictors of cloze scores. A five-factor model explained 37.2% of variance in the data; brief descriptions of respondents associated with each factor are given. Age accounted for 11.6% of the variance, higher than any other factor. Younger respondents were significantly more likely to score low on the more difficult cloze passage, to read books less frequently, and to read tabloid newspapers.
ANALYSIS AND APPLICATIONS OF SOCIAL NETWORK FORMATION

Nowadays people and organizations are more and more interconnected in the forms of social networks: the nodes are social entities and the links are various relationships among them. Social network theory and methods of social network analysis (SNA) are being increasingly used to study such real-world networks in order to support knowledge management and decision making in organizations. However, most existing social network studies focus on the static topologies of networks. The dynamic network link formation process is largely ignored. This dissertation is devoted to studying such dynamic network formation processes to support knowledge management and decision making in networked environments. Three challenges remain to be addressed in modeling and analyzing the dynamic network link formation processes. The first challenge is about modeling the network topological changes using longitudinal network data. The second challenge is concerned with examining factors that influence formation of links among individuals in networks. The third challenge regards link prediction in evolving social networks. This dissertation presents four essays that address these challenges in various knowledge management domains. The first essay studies the topological changes of a major international terrorist network over a 14-year period. In addition, this paper used a simulation approach to examine this
On Written Corrective Feedback in L2 Writing.

Truscott (1996) questions the practicability of grammar correction, and he believes that written corrective feedback (WCF) is not only a waste of time, but even harmful to the students as well. This has led to a great deal of discussion and research on WCF in second-language (L2) writing. Ferris (1999) is the representative opponent of Truscott’s point of view, who argues that WCF should not be abandoned in that it can improve the accuracy of L2 learners’ writing. Many empirical studies have been conducted and the results support Ferris’ view that WCF is useful in promoting the development of L2 writing. This paper gives a literature review from a dichotomy perspective of WCF.
Comparison of catch responses between a tetraplegic patient using an FES system, and healthy control subjects

A closed loop control FES system was developed to provide a C5-tetraplegic patient with lateral hand grasp. Cutaneous mechanoreceptors, sensitive to slips across the skin, were applied to control the stimulation intensity of the system. The authors investigated the 'catch responses' to slip events during lateral hand grasp tasks and compared them to the responses of five healthy control subjects. Slips of the grasped object were initiated by increasing the tangential pulling force. Different pulling loads and object textures were used in this study, the slip distances increased with higher pulling loads and more slippery surfaces. For the sandpaper surface the authors did not observe significant differences between the SCI-patient and the control subjects with respect to reaction time and slip distances.
An Atlas of Academic Practice in Digital Times

Abstract In the current literature on the university it is generally accepted that processes of digitization play an important role regarding both the daily functioning of the university as an institution and the academics that give shape to it. This article contributes to our understanding of the role that digitization plays in contemporary academic practices and does this by adopting a relational theoretical framework informed by sociomaterial studies. Furthermore, the article introduces a specific interview technique as methodological approach and makes use of topological visualizations in order to qualitatively analyze the composition of academic work in digital times. As such, combining textual and visual analysis, the article should be conceived as an explorative atlas. The atlas gives an account of how daily academic practices are relationally composed, by focusing on the spatiotemporal constellations enacted in these practices, and on how the digital acts and operates in these practices. Based on three profiles of academic practices, this atlas concludes by exploring whether contemporary academic practices are characterized by a typical mode of existence, and gives some pointers as to how this mode of existence of the university is typically enacted nowadays.
Stay or Switch: An Organizational Behavior and Management Science Joint Classroom Exercise

We use a simple probabilistic decision problem as the basis for a three-hour exercise taught jointly by faculty from organizational behavior and management science. The exercise requires students to commit to a decision, and then defend their decision to other students. The problem is counter-intuitive, hence the bulk of students make an incorrect decision. This provides insight regarding irrational decision making behaviors, experiential learning of important organizational behavior topics, and an enhanced perspective on the value of analytical techniques.
Where Do Molecular Biology Graduate Students Find Information?

ABSTRACT Molecular biology graduate students read the traditional, highly regarded scientific journals, yet do not fully utilize bibliographic databases to find information. Instead, molecular biology graduate students rely on the extensive reservoir of information in bioinformatics databases as well as that within the National Library of Medicine's PubMed. Graduate students learn about bioinformatics databases in their laboratories, not the campus library, thereby bypassing the library and adopting the laboratory as their information community. The data presented suggest that science and technology librarians must expand their knowledge base to include these resources as well as provide instruction that is both palatable and transparent to the next generation of leaders in the field of molecular biology.
Measuring Interactivity in Video Games

Video games are a popular form of new media, and their use is impacting multiple fields of study within the communication discipline. For instance, research programs in mass communication, health, instructional, feminist/gender, interpersonal, and intercultural communication have all examined video games. Interactivity is the hallmark of video games and consequently is a common concept in the video game literature. While video game interactivity (VGI) is still an under-specified concept, previous research suggests that interactivity has the potential to moderate both positive and negative effects of video games, and therefore it is crucial for understanding general video game effects. We developed a theoretical model of video game interactivity and tested a multidimensional scale to assess video game interactivity across five studies using six independent samples. Exploratory and confirmatory factor analyses as well as item analyses revealed a reliable and valid metric consisting of six dimensions of video game interactivity.

Coverage of Periodicals in National Deposit Libraries

Abstract National Deposit Libraries usually own the largest collection of periodicals published in a specific country. This paper describes a method to study the coverage of periodicals in deposit libraries. The authors used two checklists to determine coverage of the periodicals collection in the Deposit Library of the Koninklijke Bibliotheek, the National Library of the Netherlands. Coverage was found to be circa 94 and 84 percent, respectively. The nature of the checklists and the selection criteria of the Deposit Library can affect results. These considerations should also be taken into account when comparing coverage among deposit libraries of different countries.
