RDFStats - An Extensible RDF Statistics Generator and Library

In this paper RDFStats is introduced, which is a generator for statistics of RDF sources like SPARQL endpoints and RDF documents. RDFStats does not only provide a statistics generator, but also a powerful API for persisting and accessing statistics including several estimation functions that also support SPARQL filter-like expressions. For many Semantic Web applications like the Semantic Web Integrator and Query Engine (SemWIQ), which is currently developed at the University of Linz, detailed statistics about the contents of RDF data sources are very important. RDFStats has been primarily designed and implemented for the SemWIQ federator and optimizer, but it can also be used for other applications like linked data browsers, aggregators, or visualization tools. It is based on the popular Semantic Web framework Jena developed by HP Labs Bristol and can be easily extended and integrated into other applications.
Implementation of Optimal Routing Algorithms Based on Pipeline Flux Leak Monitoring Networks

Flow against pipeline leakage and the pipe network sudden burst pipe to pipeline leakage flow for the application objects, Optimal Routing Algorithms is designed in pipeline leak monitoring. Based on the property of Markov chain for network data, a new estimator with particle filter is proposed for congestion control in this paper. In the context of a reconfigurable transport protocol framework, we propose a QoS-aware Transport Protocol (QSTP), specifically designed to operate over QoS-enabled networks with bandwidth guarantee. QSTP combines QoS-aware TFRC congestion control mechanism, which takes into account the network-level bandwidth reservations, with a Selective ACKnowledgment (SACK) mechanism in order to provide a QoS-aware transport service that fill the gap between QoS enabled network services. Simulation results show that Network congestion avoidance strategy with particle filter can improve the bandwidth utilization, TCP friendliness and reduce the packet drop rate in Pipeline Flux Leak Monitoring networks. This way, network resources are optimally distributed and the number of multicast trees that can be setup is maximized.
Internet addiction and social satisfaction

Michael Attanasio INTERNET ADDICTION AND SOCIAL SATISFACTION 2007/08 Dr. Eleanor Gaer Master of Arts in Mental Health Counseling and Applied Psychology The purpose of this study was to determine the effects of Internet addiction on a participant's level of satisfaction with their social life. Participants were gathered from both Rowan University and the Intemrnet at large (n = 122) and asked to complete an online survey. The survey contained criteria questions for Internet addiction and social satisfaction as well as numerous questions that determined the effects of the participant's Internet usage on various aspects of their life (social, academic, job performance, etc). Results show that knowing a participant's level of Internet addiction allows researchers to weakly predict their level of satisfaction with their social life. Participants who qualified as Internet addicted were found to have a lower level of social satisfaction when compared to those who were not addicted. This study also found that males generally take more risks and have more detrimental consequences from Internet addiction than females. This study has found that Internet addiction can have significant negative impacts in many aspects of life and that more research in needed on the topic.
Finite-element analysis of the effect of geometric tolerances on performance over a frequency band

Uncertainties in the geometry of a microwave device introduced by the manufacturing process lead to a variation in the device performance. To predict this variation by repeated computational field analysis of large numbers of randomly perturbed geometries is excessively costly. An alternative is to make use of the derivatives of the performance with respect to each geometric variable, cheaply available over the whole frequency band when the appropriate finite-element method is used for the analysis. Results are presented for an E-plane waveguide bend with six geometric variables; the standard deviation of the return loss computed with the proposed method agrees well with the value obtained by direct analysis of 128 randomly perturbed geometries. A half-height capacitive metallic post in a waveguide is also analyzed, and the standard deviation of the equivalent-circuit reactances is obtained.
Electronic Communications of the EASST Pre-proceedings Proceedings of the Eighth International Workshop on Graph Transformation and Visual Modeling Techniques ( GT-VMT 2009 ) Improved Flexibility and Scalability by Interpreting Story Diagrams

In this paper, we present an interpreter for Story Diagrams working on Eclipse Modeling Framework (EMF) models. The interpreter provides a more flexible and, under certain circumstances, a more scalable solution than the compiled Java code generated from Story Diagrams by Fujaba. Story Diagrams can now be modeled and executed within Eclipse. They can be modified and re-executed by the Story Diagram interpreter immediately without recompiling the source code and restarting the application. Our implementation also supports higher-order transformations by using Story Diagrams to modify other Story Diagrams. While interpretation obviously results in performance drawbacks, we demonstrate that the Story Diagram interpreter is able to improve the performance in certain worst-case situations compared to the average generated code. This is achieved by a dynamic ordering of the matching process, which considers the actual number of elements in an association at runtime. Such a dynamic ordering can minimize the matching effort considerably. In contrast, Fujaba generated code uses a static matching strategy. Whereas the Fujaba Story Diagrams have potentially high performance fluctuations, the performance of the Story Diagram interpreter is more steady and more scalable compared to the generated Java code.
DESIGN FOR MAINTAINABILITY: THE INNOVATION PROCESS IN LONG TERM ENGINEERING PROJECTS

Introduction In this paper we are concerned with design and innovation in the context of long-term service driven engineering projects. These are defined as capital projects which involve, not just the manufacture or construction, delivery and/or commissioning of a capital facility, but also the long term operation and/or maintenance of that facility for the client. We argue that long-term projects create a particularly complex context for the management of innovation. The introduction of additional stakeholders and interest groups, in the form of an expanding project consortium, present particular difficulties of coordination for project managers and those concerned with managing design and innovation. The requirement for the facility provider to operate and maintain it throughout its life places a premium on technical and organisational innovations that reduce through-life cost rather than first cost. As such this may be regarded as a subtly new design paradigm. However, we also find that there are many barriers to the diffusion of this objective across all of the project actors; in particular, the design process(es) underpinning capital goods project are observed to be contextualised in different business, cultural and strategic environments. The case studies demonstrate the complexities inherent in the coordination of design and innovation in such projects and the multiple and sometimes conflicting objectives which designers are presented with. Nevertheless, the cases reveal a number of ways in which new organisational arrangements have emerged from attempts to deal with these difficulties and also some of the mechanisms that have helped companies to identify the design implications of future maintenance requirements. This paper is based upon research relating to two long-term engineering projects from the capital goods industry. They were firstly, ALSTOM Transport's project to supply and maintain a fleet of high-speed tilting trains for Virgin Trains on the West Coast Main Line (WCML) and Clarke Chapman's contract for the refurbishment, upgrading, operation and maintenance of wharf-side materials handling facilities on behalf of a newly privatised steelworks in Argentina. Background Service led, long-term capital goods projects Like many other enterprises, low volume capital goods firms in recent years have faced increasing internationalisation of markets and production and increasing competitive pressures. In addition, and due in part to the nature of the product or service they provide, many of them have been affected directly by changing regulation (e.g. environmental regulation) and/or deregulation (e.g. privatisation). These drivers have brought about fundamental changes in the sources and nature …
Supporting Learners as users

S oftware designers following a user-centered design philosophy try to provide software that helps users achieve their task goals. Wordprocessing programs help users to create, format, and spellcheck text, if that's the goal of the users. Checkbook programs help users to record transactions and reconcile their account with the bank, if that's their goal. But sometimes, the user's goal is not the same as the explicit task that the software was designed for. That's the state that learners are in when they attempt to meet their learning goals through performing some task. For example, you may want to learn about physics by programming physics simulations, learn something about statistics by exploring in a spreadsheet or with Mathematica, or learn about yourself by keeping a personal journal in a wordprocessing program. Many adults in lifelong learning programs are attempting this kind of learning, where they are using their real work workstations to support their learning activity, too. The learning becomes even more complicated ff the learner does not already know how to program or to use spreadsheets or Mathematica. This latter situation is common in undergraduate education where a student is asked to use the tool used by professionals while still learning the content of their domain (e.g., an engineering student learning to use a mathematical modeling language like Matlab while learning mathematical modeling or digital signal processing). Learners don't have a single goal or task when they are using an application program, but two or more. The goals may be hierarchically arranged in terms of importance, but they are often pursued in parallel. Primarily, their task is to learn some content-or maybe, to get a good grade, and to do whatever learning is necessary to get that good grade. Secondarily, their task may be to program, to build a spreadsheet, or to write. Related to that secondary goal may be to learn to program, to build a spreadsheet, or even to use the word processor. I call this model of learner as learner-as-user, which contrasts with:
THE 1000 BRIGHTEST HIPASS GALAXIES: H I MASS FUNCTION ANDHI

We present a new accurate measurement of the H I mass function of galaxies from the HIPASS Bright Galaxy Catalog, a sample of 1000 galaxies with the highest H I peak flux densities in the southern ( � < 0 ◦ ) hemisphere (Koribalski et al. 2003). This sample spans nearly four orders of magnitude in H I mass (from log(MHI∕ M⊙) + 2 logh75 = 6.8 to 10.6) and is the largest sample of H I selected galaxies to date. We develop a bivariate maximum likelihood technique to measure the space density of galaxies, and show that this is a robust method, insensitive to the effects of large scale str ucture. The resulting H I mass function can be fitted satisfactorily with a Schechter function with faint-end sl ope � = -1.30. This slope is found to be dependent on morphological type, with later type galaxies giving steeper slopes. We extensively test various effects that potentially bias the determination of the H I mass function, including peculiar motions of galaxies, large scale structure, selection bias, and inclination effects, and qu antify these biases. The large sample of galaxies enables an accurate measurement of the cosmological mass density of neutral gas: HI = (3.8± 0.6)× 10 -4 h -1 75 . Low surface brightness galaxies contribute only � 15% to this value, consistent with previous findings.

Predictive Mechanisms increase Efficiency in Robot-supported Assemblies: An Experimental Evaluation

The presented work focuses on investigating the influence of different hand-over timing strategies on the fluency and efficiency of a human-robot team in an assembly task. To this aim, four different timing strategies were experimentally performed with 37 volunteers: (I) a fixed time interval between two hand-overs, (II) a reactive behavior, where the robot is triggered by the human, (III) a fixed time intervals depending on the current component, and (IV) a predictive assembly duration estimation algorithm. During the experiment, the time-to-completion of the task and the waiting times for human and robot were measured as reciprocal indication for the efficiency and respectively the fluency of the team. The results indicate that the efficiency of the human-robot team is significantly increased using a predictive timing strategy, because it enables the robot to provide the needed component just-in-time. The decrease in waiting times for the human worker leads to improved fluency of the collaboration. In addition, the predictive strategy enables the robot to perform preliminary tasks if no assistance is needed. Therefore, a nearly full usage of both partners’ capacities can be reached.
Towards situated knowledge acquisition

Situated cognition is not a mere philosophical concern: it has pragmatic implications for current practice in knowledge acquisition. Tools must move from being design-focused to being maintenance-focused. Reuse-based approaches (e.g. using problem-solving methods) will fail unless the reused descriptions can be extensively modified to suit the new situation. Knowledge engineers must model not only descriptions of expert knowledge, but also the environment in which a knowledge base will perform. Descriptions of knowledge must be constantly re-evaluated. This re-evaluation process has implications for assessing representations
A distributed multipurpose mail guard

We describe a mechanism for incorporating a mail guard mechanism together with automatic, mandatory, and fully transparent digital signatures and encryption for message traffic embedded into the operating system of individual network nodes. By intercepting all inbound and outbound network traffic and analyzing for pertinent information using generalized Buchi automata, the guard mechanism can enforce the application of (centralized) mail security policies without requiring any support from mail clients. An implementation based on modular modifications to the Microsoft Windows NT/2000/XP family of operating systems and OpenPGP-based messaging is described.
Random-noise Contamination Assessment of Images via Non-parametric Hypothesis Testing on Wavelet Coefficients

Images encountered in our daily lives typically contain random noise of some level. The human visual system (HVS) has the ability to see through such noises at low level. It is desirable to replicate this ability in an image quality assessment method. Extensive experiments found that well-established full-reference image quality assessment methods, such as mean square error (MSE), structure similarity index (SSIM) by Wang et al. [2004] and peak signalto-noise ratio (PSNR), may poorly mimic the human visual system in this regard. In this article we propose a new full-reference image quality assessment method, namely, wavelet-based non-parametric structure similarity (WNPSSIM) index, based on a non-parametric test of the hypothesis of identical images. The test is conducted on the wavelet domain to take advantage of the belief that wavelet transform provides an alternate representation of image data that is more in sync with the HVS (Field [1999]; Portilla et al. [2003]; Chandler and Hemami [2005]). Experimental comparisons demonstrate that WNPSSIM performs better than some well-known image quality assessment methods when the images involved are corrupted with random noises.

Flow-Based Multistage Co-Allocation Service

The concept of co-allocation provides a simple mechanism to request and bind resources in a coordinated fashion in Grids across virtual organization boundaries. We have designed an advanced multistage co-allocation strategy based on resource hierarchies defined through user-specific patterns. The model manages simple flows between resources to perform managed job executions. We demonstrate the usefulness of our model on several examples and discuss advantages and disadvantages of the model.
A Probabilistic Dependent Type System based on Non-Deterministic Beta Reduction

We introduce Probabilistic Dependent Type Systems (PDTS) via a functional language based on a subsystem of intuitionistic type theory including dependent sums and products, which is expanded to include stochastic functions. We provide a sampling-based semantics for the language based on non-deterministic beta reduction. Further, we derive a probabilistic logic from the PDTS introduced as a direct result of the Curry-Howard isomorphism. The probabilistic logic derived is shown to provide a universal representation for finite discrete distributions.
French anthroponyms as a heterogeneous category

In natural languages, personal nouns (e.g., madame, ministre) are used very frequently and it is usually not very difficult to identify and interpret them in texts. If one tries to define them more precisely, however, one is confronted with a series of challenges. This contribution gives an overview of several types of difficulties that can be observed when trying to establish distinctions between personal nouns and other words. They are related to lexical differences between (personal) nouns and (personal) names, the referential boundaries of humanness, some morphological and semantic properties of French personal names, their syntactic behavior as personal nouns in French as well as the types of predications that may be used in order to distinguish between personal noun use and other uses.1
Thermometer-to-binary decoders for flash analog-to-digital converters

Decoders for low power, high-speed flash ADCs are investigated. The sensitivity to bubble errors of the ROM decoder with error correction, ones-counter, 4-level folded Wallace-tree, and multiplexer-based decoder are simulated. The ones-counter and multiplexer-based decoder, corresponding to the error insensitive and hardware efficient cases, are implemented in a 130 nm CMOS SOI technology. Measurements yield an ENOB of about 4.1 bit for both, and energy consumption of 80 pJ and 60 pJ, for the respective decoders. Hence we conclude that the MUX-based decoder seems to be a good choice with respect to area, efficiency, and speed.
FlexNet - A flexible neural network construction algorithm

Dynamic neural network algorithms are used for automatic network design in order to avoid time consuming search for finding an appropriate network topology with trial & error methods. The new FlexNet algorithm, unlike other network construction algorithms, does not underlie any constraints regarding the number of hidden layers and hidden units. In addition different connection strategies are available, together with candidate pool training and the option of freezing weights. Test results on 3 different benchmarks showed higher generalization rates for FlexNet compared to Cascade-Correlation and optimized static MLP networks.
Effect of Cool and Hot Exhaust Gas Recirculation (EGR) on the Performance of Multi-Cylinder Compression Ignition Engine Fueled With Blends of Diesel and Methanol

Performance of a direct injection multicylinders diesel engine fueled with dieselmethanol blends using hot and cool EGR were investigated. The influence of some engine variables such as equivalence ratio, load, engine speed and injection timing were studied. The test were conducted with hot EGR and repeated with cool EGR. The results were compared with that from engine operation with neat diesel and 90% diesel+10% methanol. The results show that different behaviors were existed in the combustion between the diesel-methanol blends than that of diesel fuel. EGR which is a useful tool in reducing NOx affects engine performance largely. Adding methanol to diesel reduced the harm effects of EGR on engine performance by increasing available oxygen inside combustion chamber. Cool EGR gives better thermal efficiency, volumetric efficiency, brake specific fuel consumption (bsfc) and brake power (bp) compared to hot EGR. Advancing injection timing improved engine performance when EGR was added.
The Multiple Number Field Sieve for Medium and High Characteristic Finite Fields

In this paper, we study the discrete logarithm problem in medium and high characteristic finite fields. We propose a variant of the Number Field Sieve~(NFS) based on numerous number fields. Our improved algorithm computes discrete logarithms in $\mathbb{F}_{p^n}$ for the whole range of applicability of NFS and lowers the asymptotic complexity from $L_{p^n}(1/3,(128/9)^{1/3})$ to $L_{p^n}(1/3,(2^{13}/3^6)^{1/3})$ in the medium characteristic case, and from $L_{p^n}(1/3,(64/9)^{1/3})$ to $L_{p^n}(1/3,((92 + 26 \sqrt{13})/27))^{1/3})$ in the high characteristic case. Version 2 contains an erratum.
Long‐Term Prognostic Risk in Lower Extremity Peripheral Arterial Disease as a Function of the Number of Peripheral Arterial Lesions

Background Although patients with peripheral artery disease (PAD) are known to have an increased risk of adverse prognosis, simple techniques to further risk‐stratify PAD patients would be clinically useful. A plausible but unexplored factor to predict such risk would be greater disease burden, manifested as multiple lower extremity lesions. The aim of this study was to examine the association between having multiple versus isolated lower extremity PAD lesions and long‐term prognosis. Methods and Results A prospective cohort of 756 newly diagnosed PAD patients underwent duplex ultrasound testing to determine the number of lower extremity lesions. Cox regression models examined the independent association of lesion number (≥3 and 2 versus 1) and adverse prognosis (defined as a composite end point comprising first occurrence of either lower extremity amputation, admission for heart failure, nonfatal stroke, myocardial infarction, or unstable angina or mortality), adjusting for demographic and clinical risk factors. Analyses were replicated using an advanced Cox‐based model for multiple events. A total of 173 patients (23%) had ≥3 lesions, 197 (26%) had 2 lesions, and 386 (51%) had 1 lesion. After a median follow‐up of 3.2 years, patients with ≥3 lesions had an increased risk of experiencing a first adverse event (adjusted hazard ratio 1.60, 95% CI 1.08–2.38, P=0.020) and an increased risk of having multiple events (adjusted hazard ratio 1.53, 95% CI 1.08–2.18, P=0.018). Patients with 2 lesions had a prognosis similar to those with 1 lesion. Conclusions Among PAD patients, a greater number of lesions is associated with an increased risk of an adverse prognosis over 3 years of follow‐up. Assessing the number of lower extremity lesions might serve as a simple risk‐stratification tool at initial PAD diagnosis.
