A spell checker and corrector for the native South African language, South Sotho
Authors: L. A. Grobbelaar, J. D. M. Kinyua
Venue: Proceedings of the 2009 Annual Conference of the Southern African Computer Lecturers' Association (2009)

We describe a multithreaded, spell checking and correcting software application for the Windows platform, called eSpellingPro sa Sesotho sa Leboa. The application is specifically targeted to check South Sotho typed text for misspelled words, suggest correctly spelled words for the identified misspelled words and incorporate a degree of automatic correction of the incorrectly spelled words. The biggest motivation behind the development of this system, a custom spell checking and correcting application for this indigenous South African language, stemmed from evidence that had been gathered that suggested the average twenty year old South Sotho individual's spelling-skills had deteriorated. When considering the need to create error free documents, for example, a legal document in South Sotho, substandard spelling-skills could pose possible problems. Spell checking software does exist for the South Sotho language, but not for checking and correcting. Additionally, the system has the ability to translate South Sotho words into their Afrikaans and English equivalents, adding functionality. The application also has simple features of existing spell-checkers for example the ability to change the font, the font-size, to apply bold, italics or both to a word, underline a word, select all the text in the document and to print the document. Although South Sotho is not a language with high inflection, the application also checks for inflection, for example when the user enters two words as one. To accomplish faster checking, flagging and suggestion operations, multithreading was used in certain modules.

Handbook of Visual Languages for Instructional Design: Theories and Practices
Authors: Luca Botturi, Luca Botturi, Todd Stubbs
Venue: Premier Reference Source (2007)

The more complex instructional design (ID) projects grow, the more a design language can support the success of the projects, and the continuing process of integration of technologies in education makes this issue even more relevant. The Handbook of Visual Languages for Instructional Design: Theories & Practices serves as a practical guide for the integration of ID languages and notation systems into the practice of ID by presenting recent languages and notation systems for ID; exploring the connection between the use of ID languages and the integration of technologies in education, and assessing the benefits and drawbacks of the use of ID languages in specific project settings.
Transducer Minimization and Information Compression for NooJ Dictionaries
Authors: Slim Mesfar, Max Silberztein
Venue: Proceeding of the 2009 conference on Finite-State Methods and Natural Language Processing: Post-proceedings of the 7th International Workshop FSMNLP 2008 (2009)

In this paper, we describe the use of an incremental construction method of minimal, acyclic, deterministic FST. The approach consists in constructing a transducer in a single step by adding new strings one by one and minimizing the resultant automaton incrementally. Then, we present a new method to encode the morphological information associated with the dictionary entries. The new encoding unifies a large number of word forms' analyses, thus reducing the number of terminal states of the dictionary's FST, that triggers a more efficient minimization process. Finally, we present experimental results on the FST that represents the Arabic dictionary.
Improving Location Fingerprinting through Motion Detection and Asynchronous Interval Labeling
Authors: Philipp Bolliger, Kurt Partridge, Maurice Chu, Marc Langheinrich
Venue: Proceedings of the 4th International Symposium on Location and Context Awareness (2009)

Wireless signal strength fingerprinting has become an increasingly popular technique for realizing indoor localization systems using existing WiFi infrastructures. However, these systems typically require a time-consuming and costly training phase to build the radio map. Moreover, since radio signals change and fluctuate over time, map maintenance requires continuous re-calibration. We introduce a new concept called "asynchronous interval labeling" that addresses these problems in the context of user-generated place labels. By using an accelerometer to detect whether a device is moving or stationary, the system can continuously and unobtrusively learn from all radio measurements during a stationary period, thus greatly increasing the number of available samples. Movement information also allows the system to improve the user experience by deferring labeling to a later, more suitable moment. Initial experiments with our system show considerable increases in data collected and improvements to inferred location likelihood, with negligible overhead reported by users.
Collaborative end-user development on handheld devices
Authors: Navid Ahmadi, Alexander Repenning, Andri Ioannidou
Venue: Proceedings of the 2008 IEEE Symposium on Visual Languages and Human-Centric Computing (2008)

Web 2.0 has enabled end users to collaborate through their own developed artifacts, moving on from text (e.g., Wikipedia, Blogs) to images (e.g., Flickr) and movies (e.g., YouTube), changing end-user’s role from consumer to producer. But still there is no support for collaboration through interactive end-user developed artifacts, especially for emerging handheld devices, which are the next collaborative platform. Featuring fast always-on networks, Web browsers that are as powerful as their desktop counterparts, and innovative user interfaces, the newest generation of handheld devices can run highly interactive content as Web applications. We have created Ristretto Mobile, a Web-compliant framework for running end-user developed applications on handheld devices. The Web-based Ristretto Mobile includes compiler and runtime components to turn end-user applications into Web applications that can run on compatible handheld devices, including the Apple iPhone and Nokia N800. Our paper reports on the technological and cognitive challenges in creating interactive content that runs efficiently and is user accessible on handheld devices.
Computer-aided design, analysis and optimization of HMIC SOP broadband balanced amplifier
Authors: Said H. Ibrahim
Venue: WSEAS Transactions on Circuits and Systems (2009)

The purpose of this paper is to present a complete design and analysis of new HMIC 3.5-4.5 GHz broadband balanced amplifier modules using microstrip technology. Two different modules are designed and analyzed. Each module is implemented in a single substrate. The first module used Lange couplers as power splitters and combiners while the second used branch couplers. The components of the modules are designed using full-scale computer simulation program, performed by the author and named as MSDES, which takes fully into account all the discontinuities included in the microstrip lines; while the modules are analyzed and optimized using APLAC V7.61 software. A short and efficient CAD procedure for the broadband amplifier design is introduced. The first step is to design an initial narrowband high-gain microstrip amplifier at a center frequency equal to 4 GHz. The second step is to optimize the initial lengths and widths of the input and output microstrip-matching circuits to get the broadband amplifier over the range 3.5-4.5 GHz. The analyses of both narrow and broadband amplifiers are introduced in addition to the complete analysis of the designed 3.5-4.5 broadband balanced amplifier modules. The analysis of the designed balanced amplifier modules shows better efficiency and good performance. The complete AC schematic diagrams of the designed balanced amplifier modules are presented. These modules can be used in many applications including sensors, pulse Doppler communications, airborne radars, traffic control radars and satellite communications.

Authors: Jia-Yi Lu, Eva Heinrich, Isaac Pak-Wah Fung
Venue: Proceeding of the 2005 conference on Towards Sustainable and Scalable Educational Innovations Informed by the Learning Sciences: Sharing Good Practices of Research, Experimentation and Innovation (2005)

Formative assessment plays an essential role in helping students to gain deeper understanding of their subject areas. Implementing formative assessment in an e-learning environment by working with samples of marked student work provides an innovative approach of teaching and learning. A learning exercise of the implementation of learning from marked student work in an e-learning environment was conducted with second year software engineering students. The exercise was based around examples of marked student work and involved a four-step process. As an initial step to evaluate the effectiveness of learning from marking student work, a survey was conducted. It obtained information on the level of student participation, perceptions on contribution to student learning and attitudes to an interactive learning process. The results suggested that the level of participation in the learning exercise is fairly high and the perception on learning benefits is very positive. Students welcome and appreciate the opportunity to receive feedback on their own work. These results have encouraged us to continue the work with marked examples of student work and to proceed towards a more interactive learning process that facilitates peer-feedback and discussion.
Suggestions of Lyee: A Framework on Software Methodological Thinking
Authors: Fumio Negoro
Venue: Proceeding of the 2005 conference on New Trends in Software Methodologies, Tools and Techniques: Proceedings of the fourth SoMeT_W05 (2005)

This study considers our thinking is comprised of the set of something. Something in this study is cited as existences resident in our mind. This study considers the existences can be defined by certain rules. What are they? In this study, they are what cannot be negated, nor affirmed. The rules are introduced to the limits of our thinking, by using Whole, Part, Static, Dynamic, Synchronous, Asynchronous, Memory, Assimilation, Awareness and Mind, as axiom. In this study, these concepts are defined but their rationality cannot be verified by humans. This study proposes a hypothesis of the world comprised of such rules. By the rules of this world, how Software is introduced by human intelligence is observed theoretically. “Lyee” is meant to be this theoretical axiomatic observation. With this theoretical observation, we expect a new awareness of software is established. With this effect, for example, we can obtain universal algorithm independent of programming languages and programs. With this algorithm, we can realize automatic programming language conversion and program's diagnosis. In this paper, a theoretical observation of Lyee is proposed. Other rules and examples of concrete cases not discussed herein can be referred to other papers.
A Research-Supported Approach to Using Weblogs as a Sustainable Educational Innovation in an Australian Post-Primary School
Authors: John Turner, Adam Usher
Venue: Proceeding of the 2005 conference on Towards Sustainable and Scalable Educational Innovations Informed by the Learning Sciences: Sharing Good Practices of Research, Experimentation and Innovation (2005)

It has proven difficult to embed sustainable use of new educational technologies is schools. This paper reports on an exception to this, where research is used to support effective use by teachers and students of one such new technology, weblogs. With the teacher as a prime decision-maker supported and evaluated by Action Research methodologies, the implementation of weblogs has provided learning valued by students and teachers. This paper reports on the process undertaken within the History curriculum in a school, which draws on the insights provided through the wider educational technologies research community, and doing so provides a model for achieving sustainable and scalable use of educational technologies within school environments. This paper supports the importance of the practical context when considering the educational merit of new technologies if valued use in schools is to be achieved.

Venue: Proceeding of the 2008 conference on Legal Knowledge and Information Systems: JURIX 2008: The Twenty-First Annual Conference (2008)

We are concerned with the automatic semantic interpretation of legal modificatory provisions. We propose a novel approach which pairs deep syntactic parsing and a fine-grained taxonomy of legal modifications. Although still in a developmental stage, the implemented system can be used to annotate with meta-information modificatory provisions of NormaInRete documents.

On biased link sampling in data-driven link estimation and routing in low-power wireless networks
Authors: Hongwei Zhang, Lifeng Sang, Anish Arora
Venue: Proceedings of the 4th Annual International Conference on Wireless Internet (2008)

The wireless network community has become increasingly aware of the benefits of data-driven link estimation and routing as compared with beacon-based approaches, but the issue of biased link sampling (BLS) has not been well studied even though it affects routing convergence in the presence of network and environment dynamics. Focusing on traffic-induced dynamics, we examine the open, unexplored question of how serious the BLS issue is and how to effectively address it when the routing metric ETX is used. For a wide range of traffic patterns and network topologies and using both node-oriented and network-wide analysis and experimentation, we discover that the optimal routing structure remains quite stable even though the properties of individual links and routes vary significantly as traffic pattern changes. In cases where the optimal routing structure does change, data-driven link estimation and routing is either guaranteed to converge to the optimal structure or empirically shown to converge to a close-to-optimal structure. These findings provide the foundation for addressing the BLS issue in the presence of traffic-induced dynamics and suggest approaches other than existing ones. These findings also demonstrate that it is possible to maintain an optimal, stable routing structure despite the fact that the properties of individual links and paths vary in response to network dynamics.
Research Note---The Researcher as a Consumer of Scientific Publications: How Do Name-Ordering Conventions Affect Inferences About Contribution Credits?
Authors: Boris Maciejovsky, David V. Budescu, Dan Ariely
Venue: Marketing Science (2009)

When researchers from different fields with different norms collaborate, the question arises of how name-ordering conventions are chosen and how they affect contribution credits. In this paper, we answer these questions by studying two disciplines that exemplify the two cornerstones of name-ordering conventions: lexicographical ordering (i.e., alphabetical ordering, endorsed in economics) and nonlexicographical ordering (i.e., ordering according to individual contributions, endorsed in psychology). Inferences about credits are unambiguous in the latter arrangement but imperfect in the former, because alphabetical listing can reflect ordering according to individual contributions by chance. We contrast the fields of economics and psychology with marketing, a discipline heavily influenced by both. Based on archival data, consisting of more than 38,000 journal articles, we show that the three fields have different ordering practices. In two empirical studies with 351 faculty and graduate student participants from all three disciplines, as well as in a computer simulation, we show that ordering practices systematically affect and shape the allocation of perceived contributions and credit. Whereas strong disciplinary norms in economics and psychology govern the allocation of contribution credits, a more heterogeneous picture emerges for marketing. This lack of strong norms has detrimental effects in terms of assigned contribution credits.
Combining link and content for community detection: a discriminative approach
Authors: Tianbao Yang, Rong Jin, Yun Chi, Shenghuo Zhu
Venue: Proceedings of the 15th ACM SIGKDD international conference on Knowledge discovery and data mining (2009)

In this paper, we consider the problem of combining link and content analysis for community detection from networked data, such as paper citation networks and Word Wide Web. Most existing approaches combine link and content information by a generative model that generates both links and contents via a shared set of community memberships. These generative models have some shortcomings in that they failed to consider additional factors that could affect the community memberships and isolate the contents that are irrelevant to community memberships. To explicitly address these shortcomings, we propose a discriminative model for combining the link and content analysis for community detection. First, we propose a conditional model for link analysis and in the model, we introduce hidden variables to explicitly model the popularity of nodes. Second, to alleviate the impact of irrelevant content attributes, we develop a discriminative model for content analysis. These two models are unified seamlessly via the community memberships. We present efficient algorithms to solve the related optimization problems based on bound optimization and alternating projection. Extensive experiments with benchmark data sets show that the proposed framework significantly outperforms the state-of-the-art approaches for combining link and content analysis for community detection.

D-leaping: Accelerating stochastic simulation algorithms for reactions with delays
Authors: Basil Bayati, Philippe Chatelain, Petros Koumoutsakos
Venue: Journal of Computational Physics (2009)

We propose a novel, accelerated algorithm for the approximate stochastic simulation of biochemical systems with delays. The present work extends existing accelerated algorithms by distributing, in a time adaptive fashion, the delayed reactions so as to minimize the computational effort while preserving their accuracy. The accuracy of the present algorithm is assessed by comparing its results to those of the corresponding delay differential equations for a representative biochemical system. In addition, the fluctuations produced from the present algorithm are comparable to those from an exact stochastic simulation with delays. The algorithm is used to simulate biochemical systems that model oscillatory gene expression. The results indicate that the present algorithm is competitive with existing works for several benchmark problems while it is orders of magnitude faster for certain systems of biochemical reactions.
Reasoning about Dynamic Depth Profiles
Authors: Mikhail Soutchanski, Paulo Santos
Venue: Proceeding of the 2008 conference on ECAI 2008: 18th European Conference on Artificial Intelligence (2008)

Reasoning about perception of depth and about spatial relations between moving physical objects is a challenging problem. We investigate the representation of depth and motion by means of depth profiles whereby each object in the world is represented as a single peak. We propose a logical theory, formulated in the situation calculus (SC), that is used for reasoning about object motion (including motion of the observer). The theory proposed here is comprehensive enough to accommodate reasoning about both sensor data and actions in the world. We show that reasoning about depth profiles is sound and complete with respect to actual motion in the world. This shows that in the conceptual neighbourhood diagram (CND) of all possible depth perceptions, the transitions between perceptions are logical consequences of the proposed theory of depth and motion.
Conditional independence structure and its closure: Inferential rules and algorithms
Authors: Marco Baioletti, Giuseppe Busanello, Barbara Vantaggi
Venue: International Journal of Approximate Reasoning (2009)

In this paper, we deal with conditional independence models closed with respect to graphoid properties. Such models come from different uncertainty measures, in particular in a probabilistic setting. We study some inferential rules and describe methods and algorithms to compute efficiently the closure of a set of conditional independence statements.
