AN OPEN SOURCE ARCHITECTURE OF A WIRELESS BODY AREA NETWORK IN A MEDICAL ENVIRONMENT

This contribution describes the design and implementation of a novel Wireless Body Area Network system for healthcare monitoring, the architecture of which is based on commercially available and cost-effective hardware components, open-source software and a remote data repository for storage. In particular, the system utilizes a number of wearable medical sensors to measure different patient bio-signals which are all collected to a wearable microcomputer station. Medical sensor measurements are then categorized based on the criticality of the measurement and transmitted to a remote station. This long-range transmission is supported by a new network adaptive protocol designed to mainly transmit real-time medical data. In a prototype system, tests based on realtime and close to real-time transmission architectures have so far yielded favorable results in comparison to other existing protocols.
Proceedings of the 2006 international symposium on Wikis

It is our great pleasure to welcome you to the 2nd International Symposium on Wikis -- WikiSym 2006. As its name suggests, this is the second meeting of the academic community of research, practice, and use that has built up around lightweight editable web sites. Growing from Ward Cunningham's original wiki --- the Portland Pattern Repository --- up to Wikipedia, one of the largest sites on the Web (over 1.2 million pages in English alone at time of writing), wikis are rapidly becoming commonplace in the experience of millions of people every day. The Wiki Symposium exists to report new developments in wiki technology, to describe the state of practice, and to reflect on that experience.The call for papers for this year's symposium attracted 27 submissions of research papers and practitioner reports, on a wide variety of topics. Ten research papers and one practitioner report were accepted by the symposium programme committee and to be presented at the symposium: These presentations will make up the symposiums' technical programme. Every submitted paper was reviewed by at least three members of the programme committee; while papers submitted by committee members were reviewed by at least four committee members who had not themselves submitted papers to the symposium.The symposium proceedings also include abstracts for the keynote talks, panels, workshops, and demonstrations to provide a record of the whole of the symposium as well as an interview with Angela Beesley, the opening keynoter, on the topic of her talk.
Solving Fluid Flow Problems Using A Real-codedGenetic Algorithm With Uniform Refinement

A Genetic Algorithm with real-coded chromosomes is used to solve a potential flow problem in a contraction channel. A new uniform, successive-refinement strategy is presented wherein the algorithm starts with a coarse solution and works its way throughmulti-levelsof refinementsto arbitrarysolution resolution.Ateach level of refinement, a line-by-line sweep-through method is used to obtain incremental solutions for various parts of the flow domain, thus reducing the number of GA constraints. A finite difference grid was used as the objective function to evaluate the fitness of the chromosomes. Results are very promising for five levels of refinements totalling more than 12,000 nodes. Small population sizes were found to be most effective, often yielding solutions in less than 20 minutes. The mutation operator was also found to be of paramount importance for the speedy evolution of the algorithm.
High efficiency driver for transcutaneously coupled coils

A simple, highly efficient class-E driver circuit suitable for powering implantable electronic devices is described. Such a driver allows the design of displacement-tolerant coils. The design for a driver operating at 120 kHz is given. Through successive adjustments in frequency and duty cycle the largest current transfer ratio of peak AC current in the transmitter coil (L2) to the input DC current was obtained. The frequency of operation was 122.7 kHz with a duty cycle of 0.18. The DC input was 0.6 A at 9.0 V. The sinusoidal AC output in the Litz wire coil was 9.2 A peak with a peak voltage of 45.5 V AC. This represents an approximate DC/AC convert efficiency of 80% and a current transfer ratio of 15.3 A peak/A DC, with the lost power being dissipated in the DC feed inductor, the shunt capacitor, and the switch. The power loss in the HexFet switch was estimated to be less than 0.25 or less than 4.6% of the input power. <<ETX>>
Deadlock-free routing in InfiniBand/sup TM/ through destination renaming

The InfiniBand Architecture (IBA) defines a switch-based network with point-to-point links that supports any topology defined by the user including irregular ones, in order to provide flexibility and incremental expansion capability. Routing in IBA is distributed, based on forwarding tables, and only considers the packet destination ID for routing within subnets in order to drastically reduce forwarding table size. Unfortunately, the forwarding tables for most of the previously proposed routing algorithms for irregular topologies consider both the destination ID and the input channel. Therefore, these popular routing algorithms for irregular topologies may not be usable in InfiniBand networks because they do nor conform to the IBA specifications. In this paper we propose an easy-to-implement strategy to adapt the forwarding tables already computed following any routing algorithm that considers the destination ID and the input channel into the required IBA forwarding table format. The resulting routing algorithm is deadlock-free on IBA. Indeed, the originally computed paths are not modified at all. Hence, the proposed strategy does not degrade performance with respect to the original routing scheme.
CELL-FREE LAYER MEASUREMENTS IN A BIFURCATION MICROCHANNEL: COMPARISON BETWEEN A MANUAL AND AUTOMATIC METHODS

In the present work, in vitro blood flowing through a bifurcation microchannel was studied. The aim was to develop different automatic methods capable to measure the cell- free layer (CFL) thickness in the input and output of the microchannel. The results were compared with the trajectories of the CFL obtained manually. The method with the best results was the method that uses the binarization.
Key-aggregate Cryptosystem for reliable data Outsourcing among Cloud Storage

Cloud computing technology is widely used so that the data can be outsourced on the cloud can access easily. Different members can share that data through different virtual machines but present on the single physical machine. But the thing is user don’t have physical control over the outsourced data. The need is to share data securely among users. In this paper, we proposed a novel scheme that provides secure data storage and retrieval. Along with the security, the access policy is also hidden for hiding the user’s identity. This scheme is so powerful since we use key aggregation using the secure crypto algorithm. The novelty is that one can aggregate any set of secret keys and make them as compact as a single key, but concluding the power of all the keys being aggregated. The scheme detects any change made to the original file and if found clear the error’s. And also address the number of cipher texts usually grows rapidly without any restrictions. So we have to reserve enough cipher text classes in another hand we need to expand the public-key. Although the parameter can be downloaded with cipher texts, it would be better if its size is independent of the maximum number of cipher text classes Keywords: Aggregate key cryptosystem; Cloud storage; data sharing; key-aggregate encryption
Independent recovery in large-scale distributed systems

In large systems, replication can become important means to improve data access times and availability. Existing recovery protocols, on the other hand, were proposed for small-scale distributed systems. Such protocols typically update stale, newly-recovered sites with replicated data and resolve the commit uncertainty of recovering sites. Thus, given that in large systems failures are more frequent and that data access times are costlier, such protocols can potentially introduce large overheads in large systems and must be avoided, if possible. We call these protocols dependent recovery protocols since they require a recovering site to consult with other sites. Independent recovery has been studied in the context of one-copy systems and has been proven unattainable. This paper offers independent recovery protocols for large-scale systems with replicated data. It shows how the protocols can be incorporated into several well-known replication protocols and proves that these protocols continue to ensure data consistency. The paper then addresses the issue of nonblocking atomic commitment. It presents mechanisms which can reduce the overhead of termination protocols and the probability of blocking. Finally, the performance impact of the proposed recovery protocols is studied through the use of simulation and analytical studies. The results of these studies show that the significant benefits of independent recovery can be enjoyed with a very small loss in data availability and a very small increase in the number of transaction abortions.
JITB : a back end for just-in-time compilers

JITB (Just-In-Time Backend) is a C library for generating executable code at runtime. JITB takes as input a function written in a machine-independent assembly language with an unlimited number of registers, translates it to executable native code, and returns a Ccallable function pointer. Optional optimizations allow the user to exchange compilation speed for code quality. With all optimizations enabled on a Pentium Pro, JITB typically consumes between 600 and 2400 cycles per generated host instruction. Thesis Supervisor: Stephen A. Ward Title: Professor
Survey on Hierarchical Document Clustering Techniques Fihc & F 2 Ihc

Document clustering is an effective tool to manage information overload. By grouping similar documents together, we enable a human observer to quickly browse large document collections(18), make it possible to easily grasp the distinct topics and subtopics (concept hierarchies) in them, allow search engines to efficiently query large document collections (16) among many other applications. Hence, it has been widely studied as a part of the broad literature of data clustering. One such survey of existing clustering literature can be found in Jain et. al(19s).
Authoring Your Life: Developing an Internal Voice to Navigate Life’s Challenges (review)

the literature as it pertains to their subject matter while also linking the research to practice by forwarding best practice guidelines and recommendations within each chapter. Further, these resources take an unbiased perspective within their contents, unveiling both the potential benefits and drawbacks of intercollegiate athletics at four-year institutions and community colleges. Although there are some trade and academic resources currently available regarding the role of intercollegiate athletics in higher education, (e.g., Schulman & Bowen, 2001; Sperber, 2000), The Uses of Intercollegiate Athletics provides an updated and relatively thorough account of the important role that sport plays on college campuses and its implications for both the university and student-athlete. As stated by Hagedorn and Horton, very little research attention has been devoted to intercollegiate athletics at the community college level. As such, this edition of New Directions for Community Colleges fills a significant gap in the extant literature and provides a very promising and useful resource for coaches and administrators, as well as providing an excellent starting point for subsequent research attention by academics interested in athletics and athletes.
A cloverleaf of software engineering

We shall touch upon four issues of software engineering (SE): domain engineering, formal techniques, SE sociology, and academic software architects. First, before software can be designed one must understand its requirements; but before requirements can be formulated one must understand the domain. So we assume that requirements development is based on first having established models of the (application) domain. We illustrate facets of the railway domain. Second, we touch upon all of the three phases: domain engineering, requirements engineering and software design also being done formally, however "lite". Third, despite 35 years of formal methods, the SE industry, maturity-wise still lags far behind that of other engineering disciplines. So we examine why. Finally, in several areas, in health care, in architecture, and others, we see that major undertakings are primarily spearheaded by senior academic staff. Professors of medicine daily perform specialized surgery and treatments at hospitals. Professors of architecture design new, daring buildings for industry, and professors of civil engineering head the engineering structural design of new, daring bridges. So we speculate what a similar approach would entail for SE. The paper is provocative, it postulates, but most claims are not (but can and will be) substantiated.
Text-Enhanced Error Diffusion Using Multiplicative Parameters and Error Scaling Factor

Text-enhanced error diffusion is proposed to sharpen text regions in complex documents, including natural images with a mul- tifunctional printer. To enhance the sharpness of the text regions, the input image is segmented into text and background regions us- ing the maximum gradient difference. Edge-enhanced error diffusion is then applied to the text regions to sharpen the text, while Floyd and Steinberg's error diffusion is applied to the background regions to obtain smooth dot patterns. However, this combination of algo- rithms can generate two kinds of artifact around the text regions: boundary and dot-elimination artifacts. Boundary artifacts are a se- ries of dots distributed around text blocks, and this propagation error generated below a text line by the edge-enhanced error diffusion is largely diffused forward into the background region. Thus, to gradu- ally decrease these propagation errors, a grayscale dilation operator is processed along the boundary of a text block, thereby creating a gradual dilated transition region. Edge-enhanced error diffusion us- ing different multiplicative parameters is then applied to these re- gions. Meanwhile, dot-elimination artifacts are dot-disappearing phenomena occurring around high-frequency regions due to the characteristic of the edge-enhanced error diffusion to sharpen edge regions more. Thus, an error scaling factor is inserted in front of the error filter in the architecture of the edge-enhanced error diffusion to scale down the propagation errors. Experiments demonstrate that text readability is improved by increasing the sharpness of the text regions, and a less grainy appearance is simultaneously achieved compared with conventional edge-enhanced error diffusion in the background regions. © 2006 Society for Imaging Science and Technology.

Volatile but cue-laden: measuringagenda-setting in the onlinenewspaper environment

After more than four decades of charting a paradigmatic direction in media effects research, agenda-setting has witnessed and survived enormous challenges to its main thesis. Despite the unending efforts of scholars to explicate the theoretical and logical mechanisms of the theory, the ever dynamic milieu in which agenda-setting effects is being explored, creates additional research problems necessitates further exploration. The arrival of new media and the subsequent migration of legacy media into the virtual realm, is another instance of the challenges of agenda-setting as a theory that is capable of unpacking media effects. While some scholars believe in the efficacy of agenda-setting in the new media environments, others argue along an attenuation perspective. Although a number of empirical approaches have been deployed to establish the continual heuristic value of agenda-setting in the age of new media, little, if any, attempt has been made to synthesise the findings into a coherent body. This review provides clues on the salient-directing cues in online newspapers on the one hand, and the challenges of measuring agenda-setting effects of online newspapers on the other hand.
Advancing Information Management through Semantic Web Concepts and Ontologies

Although the majority of information that is published by the current web is aimed at human consumption, the browsers which contain this information are only able to interpret HTML mark-up to visualize this content. Semantic web intends to address the stability between human and machine. Advancing Information Management through Semantic Web Concepts and Ontologies provides an analysis and introduction on the concept of combining the areas of semantic web and web mining. Emphasizing semantics in technologies, reasoning, content searching and social media, this book aims to be an essential source for practitioners, researchers and academics alike.
On movement-based mobility tracking strategy-an enhanced version

An enhanced version of the movement-based location update with selective paging strategy proposed by Akyildiz, Ho and Lin (see IEEE/ACM Trans. Networking, vol.4, p.629-38, 1996) is presented. Although the terminal paging cost is slightly increased, a significant reduction in the location update cost is achieved. The net effect is, for low call-to-mobility ratio, a saving of around 10%-15% in the total cost (location+paging) per call arrival is achieved. Our proposal can be easily implemented in real cellular systems.
Students as decoders of graphics in mathematics

This paper reports on students’ ability to decode mathematical graphics. The findings were: (a) some items showed an insignificant improvement over time; (b) success involves identifying critical perceptual elements in the graphic and incorporating these elements into a solution strategy; and (c) the optimal strategy capitalises on how information is encoded in the graphic. Implications include a need for teachers to be proactive in supporting students’ to develop their graphical knowledge and an awareness that knowledge varies substantially across students.
Spatio-temporal equalization for wireless communication

Problems with standard cellular systems include limited bandwidth, susceptibility to interference and limits on the number of users per cell. Part of the bandwidth problem can be improved by adding adaptive equalization to standard wireless digital data links. Interference from other users and limitations on the number of users per cell are problems that can be ameliorated by adaptive beamforming antenna arrays. Both spatial (beamforming) and temporal (equalization) processing can be optimized jointly, thus providing better performance than either separately.

Utilizing Scribblenauts to increase reading comprehension and improve literacy skills of third grade students

Norris Darell Parker. UTILIZING SCRIBBLENAUTS TO INCREASE READING COMPREHENSION AND IMPROVE LITERACY SKILLS OF THIRD GRADE STUDENTS (Under the direction of Dr. Robert M. Reardon) Department of Educational Leadership, March, 2015. The LEA’s problem of practice upon which this research was focused on improving academic achievement in the areas of reading comprehension, fluency and other literacy skills. In particular, the LEA is very concerned about third grade reading scores in the light of North Carolina legislation that implements a reading proficiency test to be taken by all third grade students. The focus of this research was to use "Scribblenauts Unlimited," a commercial-off-theshelf video game to bolster the reading skills of third grade students in an elementary school located in a rural school district in eastern North Carolina. The research design of this action research study utilized pre and postassessment to measure the effectiveness of students’ involvement with “Scribblenauts Unlimited. ” The intervention time-line consisted of sixteen weeks of intervention during which two sections of students alternated the roles of intervention and control groups at the eight-week mark. The intervention was implemented for one hour per week during student computer laboratory times. The one-hour per week exposure was divided into two thirty-minute sessions, one on each of two days each week. The quantitative data consisted of participant’s scores on the Reading 3D assessment. The qualitative data was gathered by means of video observations of selected small groups of students and, snapshot insights into individual participants’ learning experiences by means of experience sampling methodology. During each intervention time, a video camera was set up in the computer laboratory and focused on a small group of four or five participants. One or two of the members of the group on which the video camera was focused were invited to “think aloud” through excerpts of the edited videos. The aim was to capture the participants’ learning experience in their own words at what they seem to be key points of their learning trajectory. At the end of each eight-week intervention session, a survey designed to measure the extent to which participants experienced flow was administered to the participants in the intervention.

An approach to semantic indexing and information retrieval Una aproximación a la indexación semántica y a la recuperación de información

This paper presents an approach to the semantic indexes contained in particular topics as well as the most important models for Information Retrieval. They will be dynamically constructed using the annotations contained in the web resources and the definitions in ontologies of the annotation terms used. The indexes are envisioned as active agents that ‘know’ what topics they can handle (i.e. find content for) based upon their own ontologies.
An Event Correlation Synchronization Algorithm for MMOG

This paper proposes a new synchronization algorithm which introduces the concept of event correlation into Timewarp algorithm. Under this synchronization mechanism, state rollback is executed only when there exists an event whose timestamp is within the rollback time and the event is related with others that should be executed after it but has been done before. The simulation results show that the improved algorithm can reduce the rollback number effectively and decrease playout delay so that MMOG's interactivity and playability are uplifted.
