Innovative Assessment and Feedback System for Structural Engineering Education

Commercial Online course management platforms are increasingly used in teaching and learning in many disciplines. However their use for setting assessment tasks in engineering education is often difficult and limited in achieving desired teaching and learning objectives. This is partly due to the nature of engineering exercise problems which often requires equation manipulation and multi-stage problem solving. This paper presents an innovative spreadsheet based tool which is designed to cater for this type of problem. The tool was developed for both formative and summative assessments and with a resource optimal capability to automate both marking and collecting timely feedback from students on their perceived learning. It aims to encourage active learning with activatable hints and to minimise plagiarism by generating individual assignment data for each student.
Moving forward with blended learning (BL) as a pedagogical alternative to traditional classroom learning

Globalisation and technology are altering our views on education and educational offerings.Technology has given birth to many new avenues for learning. To name a few, online learning,teleconferencing, the Internet, computer assisted learning (CAL), web-based distance learning (WBDL) and other technologies currently exist. In turn, they have helped to coin the term “blended learning” (BL), and although the term is still ill-defined, BL has entered into the training and education scene and is gaining popularity. BL is no longer a fad but is now expanding and getting established, although rapidly changing. When an institution makes the critical choice of delivery methods, it needs to consider various factors. One in particular that this article advocates is the need to understand the students as the primary educational client, their perspectives and experiences, and the learning support mechanism for effective learning outcomes. This qualitative study reports in some detail the experiences of a small group of postgraduate learners as they progress through their Masters and Ph.D. courses at Universiti Utara Malaysia (UUM), Malaysia. The paper looks at learning as described by the learners – it is their story, their experiences and their perspective on graduate learning experiences at the institution. In particular, this paper looks at BL and what that entails to the learners. From these findings, conclusions have been drawn regarding the role of learning support to facilitate BL and the provision of better educational experiences and outcomes at UUM. This article offers several suggestions and a discussion on the broader applications of the BL framework and the readiness of the UUM students for its implementation.
Simulation-Based Performance Analysis of 802.11a Wireless LAN

In this paper, a simulation study is presented to evaluate the performance of 802.11a wireless LAN protocol. We have simulated 802.11a in a simple network topology taking into account both physical and MAC layers characteristics. Based on simulation results we show that some transmission modes are not efficient to use without extra power control mechanisms. Our simulations confirm that FEC can increase significantly the range of coverage. Then a mechanism to select the best rate is addressed. Two algorithms, RBAR and Predicted-RBAR (PRBAR), are evaluated for 802.11a. As for 802.11b, simulations show that P-RBAR can provide maximum available throughput while RBAR achieves lower throughput in high rates.
Design of a computational model of adaptative coevolution

The purpose of the immune system is to protect our bodies from infection. The system works by recognizing the molecular signature of microbes or viruses that attack our bodies, and once identified, eliminating the foreign molecules in a variety of ways. As in previous evolutionary computation models of the vertebrate immune system , our model is limited to the interaction between B-lymphocytes and antigens. To represent these molecules using a genetic algorithm, one possibility is to make no distinction between their genotype and their phenotype, that is, simply to represent both antigens and antibodies as binary strings. Key-Words: Markov ́s chains, Boltzmann tournament selection, immune system, antigen, antibody, simulated annealing.
ARM Assembly Language: Fundamentals and Techniques

Of the 13 billion microprocessor-based chips shipped last year, nearly 3 billion were ARM-based. Since 1994, ARM has introduced five new generations of processors; however, instruction on compiling for 32 bit machines lags behind. Written for those with some background in digital logic and high-level programming, this work provides a text for new programmers and a reference for students and professionals. It focuses on what is needed to compile for ARM, details real assembly uses, and explores situations that programmers will ultimately encounter. A fully functional evaluation version of the RealView Microcontroller Development Kit from Keil accompanies the text.
Motivation for Glasgow distributed Haskell, a non-strict Functional Language

Non-strict functional languages ooer potential beneets for constructing distributed systems: namely a highly-dynamic model of distribution, a relatively high degree of distribution transparency, and the potential to abstract over distribution-control primitives. We describe our motivationfor implementing such a language, a variant of Haskell, and evaluating it. The implementation is a fusion of existing Glasgow Haskell Compiler technologies. The evaluation will be based on experiences implementing a distributed interactive simulation, and comparing it with a Java version.
Linguistic Perspectives on Second Language Acquisition: What is the logical problem of foreign language learning?

The linguistic data to which children are exposed appear to be insufficient to determine, by themselves, the linguistic knowledge that children eventually attain. The gap between available experience and attained competence forms what has been called the logical problem of language acquisition. The approach to a solution, which has been followed in linguistic theory over the past two decades, is to suggest that the gap is bridged by an innate Universal Grammar: a system of knowledge of what a human language can be and innate domain-specific procedures for arriving at a grammar. The classic statement is that of Chomsky: A consideration of the character of the grammar that is acquired, the degenerate quality and narrowly limited extent of the available data, the striking uniformity of the resulting grammars, and their independence of intelligence, motivation and emotional state, over wide ranges of variation, leave little hope that much of the structure of language can be learned by an organism initially uninformed as to its general character. (Chomsky 1965:58) Adults may also learn foreign languages. Abstractly, the logical problem of adult foreign language learning is the same as for childhood language learning: explaining how acquisition takes place, given the limitations of the data. But the problem is also different, in important ways. Foreign language learning differs in degree of success, in the character and uniformity of the resulting systems, in its susceptibility to factors such as motivation, and in the previous state of the organism: The learner already has a knowledge of one language and a powerful system of general abstract problem-solving skills.
Design of Embedded Systems Using 68HC12/11 Microcontrollers

From the Publisher: FEATURES/BENEFITS A bridge between the 68HC12 and the 68HC11Focuses on the 68HC12, but includes material for (and provides software for) the older 68HC11. A new version of ForthWHYP (Words to Help You Program)designed for use in embedded systems—WHYP can easily be installed on any 68HC12 system, including the most popular development boards from Motorola and Axiom Manufacturing. It consists of two parts-some 68HC12 subroutines that reside on the target system (typically an evaluation board) and a C++ program that runs on a PC and communicates with the 68HC12 target system through a serial line. It is a sub-routine threaded language, which means that WHYP words are just the names of 68HC12(11) subroutines. New WHYP words can be defined simply by stringing previously defined WHYP words together. The first five chapters of the text explain how to make the programming of the 68HC12 simple and interactive, and in the process develops the entire WHYP language from scratch, step by step. (The software is provided on disk with the text, and the latest versions of the software will be available on the author's web site.) An abundance of worked examples and many chapter-end exercisesRanges from simple reinforcing exercises to complete term projects. Some suggest significant design projects using some of the latest peripheral chips with references to specific web sites where data sheets can be obtained. Users can see examples of complete designs and have quick references to data sheet URLs. A detailed description of the new 68HC12 multiplication and divisioninstructions. Users can use the easier method (WHYP, Forth) for doing arithmetic, rather than using assembly language. A chapter on Fuzzy ControlProvides a detailed description of fuzzy logic as well as a discussion of how to use the built-in 68HC12 fuzzy control instructions. Develops special WHYP words that make it easier to design a fuzzy controller. Complete C++ code for the WHYP host that runs on the PCProvided with the book and described in Chs. 16 and 17. Includes both the C++ program that runs on the PC, and the 68HC12 assembly language program that runs on the target 68HC12 board.
COGNITIVE IMPACT OF INTERACTIVE MULTIMEDIA

Technology has been gradually introduced in heath education. One of the most attractive features of this technology-based education is the use of multimedia. In this article we explore the research evidence about the role that multimedia is playing in education. From that analysis we describe the most relevant features of this technology to prepare a common ground of discussion about the evaluation of its impact on educational outcomes. As part of this analysis, we organize current research evidence on the use of technology in medical education, distinguishing diverse variables involved in the process, like knowledge (declarative, procedural), learner characteristics, curricular scenario, etc. This article presents an overview of the Distributed Representations theory and its relationship with research on educational outcomes and multimedia. Next we discuss the relationship between media and diverse learning theories, proposing a theory based taxonomy for educational multimedia.
Apport de l'intelligence artificielle à la psychologie

A roof rack comprises a pair of interconnected side rails overlying and at their ends connected to a vehicle roof, and elongated caps of a flexible material overlying and enclosing a portion of each rail and interlocked therewith. Each rail is an elongated extrusion including a pair of parallel top bends along its length with spaced strips depending from the beads defining undercut corners. Out-turned flanges extend from the strips and terminate in upturned marginal ledges. The cap has a top wall that overlies the beads and a pair of side walls terminating in a pair of opposed internal supports respectively overlying the out-turned flanges and retained and interposed between the strips and marginal ledges. A pair of opposed internal anchor flanges on the side walls interlockingly engage the shoulders to secure then cap along its length to the rail.
Mestrado em Engenharia Informática e de Computadores (Perfil de Sistemas de Informação) Learning Techniques for Automatic Email Message Tagging

Automatic organization of email messages is still a challenge in machine learning. The problem of “email overload”, coined in 1998 by Whittaker et al, is presently affecting enterprise and power users. This thesis addresses automatic email organization by proposing a solution based on supervised learning algorithms that automatically labels email messages with tags. We approach tagging using previously created user-folders as tags and top-N ranking classifier output. Learning techniques are reviewed and the different fields of an email message are analyzed for their suitability for classification. Special attention is given to the textual fields (subject and body), by studying and testing different representations, different feature selection methods and several classification algorithms. The participant fields are analyzed and evaluated using classification algorithms that work with the vector-space model and a graph based representation. The different email fields are combined for classification using the classifier combination technique of Majority Voting. Experiments are done on a subset of the Enron Corpus and on a private data set from the Institute for Systems and Technologies of Information, Control and Communication (INSTICC). The data sets are extensively analyzed in order to understand the characteristics of the data. The evaluation of the system, using accuracy, shows great promise, with the experimental results presenting a significant improvement over related works.
Immersion et métaphore de l'intériorité Etude de cas : l'appartement d'Henry Townsend dans Silent Hill 4 « The Room »

Cette communication envisage le systeme des signes qui representent l’utilisateur comme metaphore de l’interiorite, a l’origine d’un mecanisme immersif de rapprochement entre le joueur et le personnage par l’effort cognitif d’identification. Les notions de metaphore et de Moi-peau, qui proposent des lectures de la structuration du Soi, sont mises en perspectives avec le dispositif de representation de soi dans les premieres minutes du Silent Hill 4 (Konami). Issu des recherches d’une these debutee en 2002 sur une approche semiopragmatique de la representation indicielle de l’utilisateur dans la communication mediatisee par ordinateur (CMO), ce travail vise a ouvrir des pistes de reflexion sur les procedes stylistiques d’utilisation de la metaphore de l’interiorite comme dynamique d’immersion en conception de produits et game-design.
Art Administration as Performative Practice / Organizing Art as Institutional Critique

A propositional rethinking of art administration within the artist-run institution, this thesis contributes new conceptualizations of operations of the artist-run centre in Canada. The suggestion is that art administration practiced therein is a specialized embodied expression of the institution as apparatus. Proposing that the Canadian artist- run context is a form of and forum for institutional critique, this analysis argues that the art administrator is a unique practice of mediation in art called “diagnostic organizing;” a negotiative role gesturing toward performative relationships to protocol. Recontextualizing art administration as embodying the interface between art and policy, this study also names “performing the context” as an experimental and critical approach to arts facilitation. The work of artist Andrea Fraser is investigated for her writing and practices of institutional critique, as is the arts presentation project Kunstverein Toronto where Co-Director’s Kari Cwynar and Kara Hamilton’s performative language and gestures communicate their facilitative practices.
MPSalsa a finite element computer program for reacting flow problems. Part 2 - user`s guide

This manual describes the use of MPSalsa, an unstructured finite element (FE) code for solving chemically reacting flow problems on massively parallel computers. MPSalsa has been written to enable the rigorous modeling of the complex geometry and physics found in engineering systems that exhibit coupled fluid flow, heat transfer, mass transfer, and detailed reactions. In addition, considerable effort has been made to ensure that the code makes efficient use of the computational resources of massively parallel (MP), distributed memory architectures in a way that is nearly transparent to the user. The result is the ability to simultaneously model both three-dimensional geometries and flow as well as detailed reaction chemistry in a timely manner on MT computers, an ability we believe to be unique. MPSalsa has been designed to allow the experienced researcher considerable flexibility in modeling a system. Any combination of the momentum equations, energy balance, and an arbitrary number of species mass balances can be solved. The physical and transport properties can be specified as constants, as functions, or taken from the Chemkin library and associated database. Any of the standard set of boundary conditions and source terms can be adapted by writing user functions, for which templates and examples exist.
Performance evaluation of handover protocols for data communication in a wireless ATM network

Using an object-oriented simulation model of a basic client-server scenario in a wireless ATM network, we evaluate the performance of different handover protocols. They are combined with different error-control protocols to support high-speed data communication by the ABR service class. We present simulation results of the ABR flow-control protocol ERICA+ and illustrate the performance impact of a new hard handover protocol.
Negotiation Using Logic Programming with Consistency Restoring Rules

We formalize negotiations using logic programming with consistency restoring rules (or CR-Prolog) [Balduccini and Gelfond, 2003]. Our formulation deals with incomplete information, preferences, and changing goals. We assume that each agent is equipped with a knowledge base for negotiation which consists of a CR-program, a set of possible assumptions, and a set of ordered goals. We use the notion of an answer set as a means to formalize the basic notions of negotiation such as proposal, response, negotiation, negotiation tree (protocol), etc. and discuss their properties.
Intérêts d'une matrice dermique acellulaire xénogénique (Mucograft ® ) dans le gain de tissu kératinisé péri-implantaire

Une fois les dents extraites, une resorption des tissus parodontaux est observee, ce qui peut entrainer un deficit de muqueuse keratinisee lors de la mise en place d’implants dentaires. En cas de deficit ou de perte de cette gencive keratinisee, le gold-standard est la realisation d’une autogreffe de tissu preleve generalement au palais. Afin d’eviter un deuxieme site operatoire, une nouvelle matrice dermique acellulaire xenogenique, Mucograft®, est apparue. Son architecture differe des autres matrices par sa bicouche de collagene. L’objectif de ce travail etait d’effectuer une revue systematique de la litterature afin de savoir si la matrice Mucograft® permet un gain de tissu keratinise reel lorsqu’elle est utilisee lors d’une extraction dentaire ou d’une chirurgie implantaire. Ainsi, les etudes tendent a montrer qu’il existe un reel gain de gencive keratinise apres la realisation d’une greffe d’une matrice dermique acellulaire xenogenique. Ce gain de gencive keratinise semble comparable a celui d’une greffe de gencive autologue. Ces resultats prometteurs sont a nuancer par le faible nombre d’etudes, des echantillons de petite taille et un faible recul clinique.
Fewer crashes caused by pilots

USA TODAY evaluated the 158 most severe domestic airline crashes on commercial planes with 15 or more seats from 1980 through 2001. The list includes accidents involving similar-sized cargo planes. The causes of the accidents were based on findings by the National Transportation Safety Board. It has yet to determine the causes of four of the five domestic airline ents since 2001. accid clude a mistake by mechanics that caused an Air Midwest plane to slam into the ground after takeoff on Jan. 8, 2003. Twenty-one people died. Thursday, the National Transportation Safety Board issued recommendations in that crash investigation aimed at improving maintenance at all airlines.
Software Techniques for Distributed Shared Memory

In large multiprocessors, the access to shared memory is often nonuniform, and may vary as much as ten times for some distributed shared-memory architectures (DSMs). This dissertation identifies another important nonuniform property of DSM systems: nonuniform communication architecture, NUCA. High-end hardware-coherent machines built from large nodes, or from chip multiprocessors, are typical NUCA systems, since they have a lower penalty for reading recently written data from a neighbor's cache than from a remote cache. This dissertation identifies node affinity as an important property for scalable general-purpose locks. Several software-based hierarchical lock implementations exploiting NUCAs are presented and evaluated. NUCA-aware locks are shown to be almost twice as efficient for contended critical sections compared to traditional lock implementations. The shared-memory “illusion”' provided by some large DSM systems may be implemented using either hardware, software or a combination thereof. A software-based implementation can enable cheap cluster hardware to be used, but typically suffers from poor and unpredictable performance characteristics. This dissertation advocates a new software-hardware trade-off design point based on a new combination of techniques. The two low-level techniques, fine-grain deterministic coherence and synchronous protocol execution, as well as profile-guided protocol flexibility, are evaluated in isolation as well as in a combined setting using all-software implementations. Finally, a minimum of hardware trap support is suggested to further improve the performance of coherence protocols across cluster nodes. It is shown that all these techniques combined could result in a fairly stable performance on par with hardware-based coherence.
A Futuristic View of Knowledge and Information Management

Knowledge Management and Information Management, often used synonymously, are concepts that librarians need to engage with in the future (if not already doing so). Librarians have a role within the organisation to demystify the concepts and to promote the benefits. Librarians and information professionals will have to envisage new ways of working, new organisational relationships, new services, and new professional roles, requiring the letting go of some much-loved 'traditional' frameworks. The future will include a blend of centralised services, such as enterprise content management systems and institutional repositories, customer relationship management systems, and enterprise-level federated search engines. The concepts of the library catalogue, authority control, classification and standards will be challenged by the rapidly expanding use of social networking tools, such as blogs and wikis.
Management Entrepreneurial et Orientation Entrepreneuriale : Deux concepts aussi différents ?

Le management entrepreneurial (Stevenson et Gumpert, 1985) peut-il etre assimile a l'orientation entrepreneuriale (Miller, 1983 ; Covin et Slevin, 1988, 1989, 1991 ; Lumpkin et Dess, 1996), concept developpe et largement utilise pour mesurer l'intensite entrepreneuriale d'une organisation ? Nous demontrons que ces deux concepts sont distincts bien que conduisant tous deux vers l'entrepreneuriat organisationnel (Brown et al, 2001). Nous soulignons que le caractere dynamique de ce type d'entrepreneuriat appelle a des recherches qualitatives supplementaires afin de donner un contenu au concept. Ceci permettrait, notamment, aux praticiens d'identifier les mecanismes et processus qui maintiennent l'intensite entrepreneuriale a un bon niveau et d'agir sur ces derniers quand cette intensite fait defaut. Ce contenu donnerait au monde academique un materiau pour reexaminer l'operationnalisation de l'orientation entrepreneuriale, necessite soulignee par Basso et al (2010).
