Usability for IT: manageability of data security technologies for client devices
Authors: Subhashini Ganapathy, Glen J. Anderson
Venue: Proceedings of the 12th WSEAS international conference on Computers (2008)

Even though many products can deliver the security needed if used properly, such products cannot succeed if they drive the IT burden too high. The paper explains manageability and usability issues as well as guidelines for producing security products that are easier for IT to manage. The findings reported in this paper are based on qualitative data from structured interviews with IT professionals in 2006 and 2007. Applying a human centered approach to security technologies will help alleviate problems associated with manageability and usability of the application.
Make IT matter: how computing can make a difference
Authors: Gregory D. Abowd
Venue: ACM SIGCSE Bulletin (2009)

Years ago I was trained as a software engineering researcher, well versed in the mathematical abstractions of programming. However, influenced by the writings and research of Mark Weiser and his Xerox PARC Ubiquitous Computing group, I started to think about a different way of doing research in computing. Computing technology, as Weiser predicted, has become so prevalent in our lives that we almost don't recognize everything that is computationally-based in our everyday world. In this talk, I will focus on how information technologies woven into our everyday lives can address significant problems in the delivery of health care for vulnerable populations. My main experience, driven by personal necessity, is with developmental disabilities, but I hope that my story will show how the integration of the physical and digital worlds makes a real difference in our lives and the lives of others.
The effects of computers on library staff and users: how can the administrator cope?
Authors: Richard W. Boss
Venue: Proceedings of the May 4-7, 1981, national computer conference (1981)

A library normally prepares for the automation of one or more functions by undertaking systematic technological and economic planning. A set of specifications is normally drawn up, setting forth the functional requirements for the system, whether that system is to be a "turnkey system" (one supplied by a vendor who provides hardware, software, installation, training and maintenance---some 85% of libraries choose this course of action), a custom development by a systems house, or an in-house effort. The budget will be drawn up at least several months in advance, setting forth the anticipated costs. While most library cost projections tend to be too conservative, the effort is nevertheless made. The area of automation planning that is most often neglected is that of the psychological impact of the new system on the library's staff and users.
Latency reduction by dynamic core selection and partial migration of game state
Authors: Paul B. Beskow, Knut-Helge Vik, Pål Halvorsen, Carsten Griwodz
Venue: Proceedings of the 7th ACM SIGCOMM Workshop on Network and System Support for Games (2008)

Massively multi-player online games (MMOGs) require low latency while supporting a large number of concurrent players, often sharing one worldwide instance of the game. As these are conflicting requirements, a common way of distributing load is by dividing the virtual environment into virtual regions. As MMOGs are world-spanning games, it is plausible to disperse these regions on geographically distributed servers. As such, we propose the use of core selection for finding an optimal server for placing a region, and support for migrating the game state to that server. The first goal relies on a set of servers and measurement of the interacting players latencies. In locating an optimal server, we anticipate a decrease in the overall latency for the majority of players. This reduction occurs by migrating the region to a server closer in proximity to the majority of players in that virtual region, thereby lowering the response time of any interaction.
Manufacturability Evaluation of Auto Panels Using Polychromatic Sets
Authors: Zhijian Zong, Xiaoying Xi, Lili Jiang, Binbin Yang
Venue: Proceedings of the 2009 International Asia Conference on Informatics in Control, Automation and Robotics (2009)

In the traditional design process of auto panels, the structure and functions of the panel are concerned more by designers, but the manufacturability is paid little attention to. Therefore, some problems appear during the manufacturing process. In this paper, a new approach, design for manufacturability using polychromatic sets, is introduced to evaluate the manufacturability of auto panels. And the systemic framework is established. Detailed explanations are given through an auto panel example. The evaluation process is described using polychromatic Sets.
Fine-Grained Continuous Usage Control of Service Based Grids --- The GridTrust Approach
Authors: Syed Naqvi, Philippe Massonet, Benjamin Aziz, Alvaro Arenas, Fabio Martinelli, Paolo Mori, Lorenzo Blasi, Giovanni Cortese
Venue: Proceedings of the 1st European Conference on Towards a Service-Based Internet (2008)

Access control techniques designed for single domain infrastructures, where users are known by domain administrators, provide considerable liberty in the usage of resources. This paradigm is not suitable for highly scalable and decentralised systems such as Grids and service oriented architectures (SOA), where resources are shared between domains, and users come from remote domains. One approach is to provide policy-driven autonomic solutions that operate a continuous monitoring of the usage of resources by users. This paper presents the services and tools offered by the GridTrust Security Framework (GSF). GSF addresses three layers of the next generation of grid (NGG) architecture: the Grid application layer, the Grid service middleware layer, and the Grid foundation layer. The framework is composed of security and trust services and tools provided at the middleware and Grid foundation middleware layers. Various business case studies are being developed to validate the GridTrust results.
E-learning tools based on transition systems
Authors: Dan Chiribuca, Iulian Pah, Emil M. Popa, Bogdan A. Brumar
Venue: Proceedings of the 8th conference on Applied informatics and communications (2008)

Due to the dynamic nature of the computing objects represented, the semantics of the specification languages used to formalize systems will be a transition system performing computation actions, while the syntax will be the linguistic expression of the actions performed by the transition system. Computing objects manipulated in computer science bear a lot of similarities with the mathematical objects produced by the systems discussed so far they also are very different. The concept of language is regarded as a communication tool that allows language users to develop knowledge, while interacting with their universe of discourse, and to communicate with each other, while exchanging knowledge, in that case for e-learning systems. The results presented here have as initial point [1], [7], [13].
A Study of Mobile Agent Tree Routes for Data Fusion in WSN
Authors: Yuzhi Wu, Lianglun Cheng
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 02 (2009)

In mobile agent based data fusion, the order of nodes visited along the route by mobile agent has a significant impact on the algorithm efficiency and lifetime of wireless sensor network. In this article, we propose a mobile agent tree routes scheme with data fusion. Considering the energy level of the sensor nodes, we construct the data fusion tree based on mobile agent to let mobile agents visit the low battery nodes less frequently, and on the contrary, nodes which have more energy will be visited more, mobile agents execute the data fusion in some nodes while mobile agents are moving. The experimental result shows, with the increase of the network scale and the amount of the sensor nodes, our proposed algorithm has less energy consumption and network delay.

Authors: V. Kevin Whitney, Jane G. Morse
Venue: Proceedings of the May 4-7, 1981, national computer conference (1981)

Many different tools and techniques for assisting application system development are available today, but there is no good method available for choosing the proper ones to use in a particular application. This paper presents a fivefold classification of application systems and the tools and techniques most suitable for each class. Characteristics of each class of applications are explained, and methods of using this analysis to select application development tools and techniques are discussed.
Using Modified Contour Features and SVM Based Classifier for the Recognition of Persian/Arabic Handwritten Numerals
Authors: Alireza Alaei, Umapada Pal, P. Nagabhushan
Venue: Proceedings of the 2009 Seventh International Conference on Advances in Pattern Recognition (2009)

In this paper, we propose a robust and efficient feature set based on modified contour chain code to achieve higher recognition accuracy of Persian/Arabic numerals. In classification part, we employ support vector machine (SVM) as classifier. Feature set consists of 196 dimensions, which are the chain-code direction frequencies in the contour pixels of input image. We evaluated our scheme on 80,000 handwritten samples of Persian numerals. Using 60,000 samples for training, we tested our scheme on other 20,000 samples and obtained 98.71% correct recognition rate. Further, we obtained 99.37% accuracy using five-fold cross validation technique on 80,000 dataset.
A novel infrastructure WLAN locating method based on neural network
Authors: Xiaole Ding, Hewu Li, Fenghua Li, Jianping Wu
Venue: Proceedings of the 4th Asian Conference on Internet Engineering (2008)

Comparing to the client based locating, infrastructure based methods do not require install special software or hardware at client side. So it not only fits for real deployment, but also supports some specific requirement (ex target tracking). Former researchers mainly adopt k-NN method in infrastructure based locating. However, its computing complexity is proportional to the size of sample set, which makes it unscalable when the system grows large. This paper proposes a novel infrastructure WLAN locating method by utilizing neural networks and a new training method to overcome the effect of different power levels of client devices. Through real deployment and testing, the result shows that the computing complexity is much lower than the k-NN method, while the accuracy is very close.
Application of Correlation-Based Regression Analysis for Improvement of Power Distribution Network
Authors: Shiho Hagiwara, Takumi Uezono, Takashi Sato, Kazuya Masu
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

Stochastic approaches for effective power distribution network optimization are proposed. Considering node voltages obtained using dynamic voltage drop analysis as sample variables, multi-variate regression is conducted to optimize clock timing metrics, such as clock skew or jitter. Aggregate correlation coefficient (ACC) which quantifies connectivity between different chip regions is defined in order to find a possible insufficiency in wire connections of a power distribution network. Based on the ACC, we also propose a procedure using linear regression to find the most effective region for improving clock timing metrics. By using the proposed procedure, effective fixing point were obtained two orders faster than by using brute force circuit simulation.
A study of fault tolerance techniques for associative processors
Authors: Behrooz Parhami, Algirdas Avižienis
Venue: Proceedings of the May 6-10, 1974, national computer conference and exposition (1974)

Associative processing techniques have been suggested for numerous application areas and have been proven to be superior to more conventional procedures for a number of specialized applications. Recent advances in computer technology and development of new architectural concepts for associative devices have made the design of larger and more flexible systems possible. Such systems are extremely complex and must be adequately protected against failures. This paper reports on the results of a study which has indicated the techniques that are applicable and difficulties that may be encountered in the design of fault-tolerant associative processors.
Telematic Drum Circle
Authors: Byeong Sam Jeon
Venue: ACM SIGGRAPH ASIA 2008 artgallery: emerging technologies (2008)

Telematic Drum Circle is an interdisciplinary art project combining telecommunications, robotics, human-computer interaction, and improvisational music. The project explores the rupture of deeper communication in the technology-mediated world and addresses the issue of global harmony by sharing participants' rhythmical spirit produced through the telematic live drum ensemble. It consists of two main components: a set of 16 robotic drums arranged in an installation space and an interactive web site networked with these drums. Each drum is representative of a geo-cultural region. Regardless of age, sex, religion, race, and culture, we all have a universal rhythm: our heartbeats. The drum is an instrument of rhythm, and I believe it can stand in for a person's heart. The heart-to-heart communication expressed on drums cuts through all the differences and blurs the boundaries. By tapping the computer keyboard while at the web site, participants around the world can remotely play the robotic instruments together, while watching a live streaming video of their ensemble broadcast online at www.TelematicDrumCircle.net.

The PHP Web programming platform became very popular in the last years. Its simplicity, easy usage and learning encourage many beginners to concentrate their efforts mainly on it. PHP however has some serious drawbacks, which can lead to the adaptation of wrong programming practices. In this article the main drawbacks of PHP are surveyed, along with the potential problems they create. Also some perspectives for the further platform improvement are considered.
Investigation of field-effect transistors fabricated by metal-ion-doped nano-titania using sol-gel technique
Authors: Leo Chau-Kuang Liau, Wen-Wei Chou
Venue: Microelectronic Engineering (2009)

In our present investigations, field-effect transistors (FETs) based on nano-TiO"2 and metal-ion-doped TiO"2 particles were fabricated and their characteristics were studied. Semiconductor characteristics of nano-TiO"2/metal-ion-doped TiO"2 films, which perform as a diode, were used in the fabrication of the FET device. The performance of the FET device was evaluated by analyzing the data obtained from source-drain current vs. voltage (I"d"s-V"d"s) by controlling the gate voltage (V"g). The on/off conditions of the transistor were feasibly performed and the threshold voltage (V"t) were determined by adjusting V"g for different types of the FET design. In addition, the influential factors, such as type of metal ions, and positions of TiO"2 and metal-ion-doped TiO"2 layers, on the performance of the FET device were also discussed in this study.
Identification of the most significant sensory and mechanical properties influencing tactile fabric comfort
Authors: Les M. Sztandera
Venue: Proceedings of the 8th conference on Applied computer scince (2008)

Engineered fabrics are being used increasingly in commercial and domain-specific systems. Such fabrics with specified consumer-desired characteristics can be computationally designed. Through the use of an extensive database that correlates sensory and mechanical properties with tactile comfort assessments, desired comfort can be predicted by measuring a limited number of properties. In this paper we are focusing on the most significant sensory and mechanical properties influencing tactile fabric comfort. Output systems can be optimized to exhibit the highest level of comfort by engineering a fabric with specific sensory and mechanical properties. This paper examines stepwise regression analysis and identifies the most significant properties influencing tactile fabric comfort. The reported Beta coefficients are the standardized regression coefficients. Their absolute magnitudes reflect their relative importance in predicting comfort values. A universe of 48 fabrics is examined to analyze and map the relations. The initial 17 mechanical and 17 sensory parameter sets are reduced to sets of 1 to 4 and 1 to 5 properties, respectively. Adjusted R2 values were 0.360 to 0.657 for mechanical and 0.713 to 0.863 for sensory parameters, reflecting sound goodness-of-fit measures, and providing reasonable ways for identifying the mechanical and sensory properties that are most significant influences on tactile fabric comfort. Elongation and hysteresis of shear force were found to be the most influential mechanical properties, while compression resilience rate and graininess were found to be the sensory properties that most impacted comfort.
Run-length variability of two-stage multiple comparisons with the best for steady-state simulations and its implications for choosing first-stage run lengths
Authors: Marvin K. Nakayama
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

We analyze the asymptotic behavior of two-stage procedures for multiple comparisons with the best (MCB) for comparing the steady-state means of alternative systems using simulation. The two procedures we consider differ in how they estimate the variance parameters of the alternatives in the first stage. One procedure uses a consistent estimator, and the other employs an estimator based on one of Schruben's standardized time series (STS) methods. While both methods lead to mean total run lengths that are of the same asymptotic order of magnitude, the limiting variability of the run lengths is strictly smaller for the method based on a consistent variance estimator. We also provide some analysis showing how to choose the first-stage run length.
"This might be stupid, but...": participatory design with community displays and postcards
Authors: Nick Taylor, Keith Cheverst
Venue: Proceedings of the 20th Australasian Conference on Computer-Human Interaction: Designing for Habitus and Habitat (2008)

We describe our experiences of designing a digital community display with members of a rural community. These experiences are highlighted by the development of printed and digital postcard features for the Wray Photo Display, a public photosharing display designed with the community, which was trialled during a popular village fair where both local residents and visitors interacted with the system. This trial allowed us to examine the relative popularity and differences in usage between printed and digital postcard, and offer insights into the uses of these features with community-generated content and potential problems encountered.

Authors: Shuhei Hamawaki, Shintaro Funasawa, Jiro Katto, Hiromi Ishizaki, Keiichiro Hoashi, Yasuhiro Takishima
Venue: Proceedings of the 15th International Multimedia Modeling Conference on Advances in Multimedia Modeling (2009)

In order to achieve highly accurate content-based music information retrieval (MIR), it is necessary to compensate the various bit rates of encoded songs which are stored in the music collection, since the bit rate differences are expected to apply a negative effect to content-based MIR results. In this paper, we examine how the bit rate differences affect MIR results, propose methods to normalize MFCC features extracted from encoded files with various bit rates, and show their effects to stabilize MIR results.
Morphological Tools for Indexing Video Documents
Authors: Claire Demarty, Serge Beucher
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

This paper proposes a local algorithm using morphological operators, which leads to several useful tools for indexing video documents. It consists of a local computation of a similarity criterion between two successive frames of a sequence, followed by the study of the temporal evolution curve of this criterion for the whole sequence. From this curve, shot transitions are extracted by means of a powerful morphological filter, the inf top-hat. At this point, we have built a cut detection tool. The local computation together with strong morphological filtering leads to a very simple, fast and computationally efficient algorithm, with a high detection rate in the case of cuts for a small level of false detections. This algorithm also gives access to a spatial model of the transition and to a selection of key frames for each shot. By applying the local similarity measure to the key frames, two other tools are built to detect inner shot changes and syntactically related shots. Finally, the relation detection is used in a newscaster detection tool.
Staying sane on the tenure track
Authors: Shane G. Henderson
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

A tenure-track appointment is a wonderful thing, but it really should come with an instruction manual. This article is a loosely-coupled collection of thoughts and advice on surviving a tenure-track appointment. The focus is on concrete tips and advice for an engineering-school appointment, which was my path, but perhaps some of the ideas are also valid in other environments, such as business schools and mathematics or computer science departments.
Power Assignment for Symmetric Communication in Wireless Sensor Networks
Authors: Joongseok Park, Sartaj Sahni
Venue: International Journal of Distributed Sensor Networks (2009)

We show that two incremental power heuristics for power assignment in a wireless sensor network have an approximation ratio 2. Enhancements to these heuristics are proposed. It is shown that these enhancements do not reduce the approximation ratio of the considered incremental power heuristics. However, experiments conducted by us indicate that the proposed enhancements reduce the power cost of the assignment on average. Further, the two-edge switch enhancements reduce the power-cost reduction (relative to using minimum cost spanning trees) that is, on average, twice as much as obtainable from any of the heuristics proposed earlier.
Spherical-Rectangular Drawings
Authors: Mahdieh Hasheminezhad, S. Mehdi Hashemi, Brendan D. Mckay
Venue: Proceedings of the 3rd International Workshop on Algorithms and Computation (2009)

We extend the concept of rectangular drawing to drawings on a sphere using meridians and circles of latitude such that each face is bounded by at most two circles and at most two meridians. This is called spherical-rectangular drawing. Special cases include drawing on a cylinder, a cone, or a lattice of concentric circles on the plane. In this paper, we prove necessary and sufficient conditions for cubic planar graphs to have spherical-rectangular drawings, and show that one can find in linear time a spherical-rectangular drawing of a subcubic planar graph if it has one.
