This study is concerned with predicting Translation Initiation Sites (TIS) in the human genome that start with the nucleotide sequence ATG. This sequence occurs 104 million times in the entire genome. However, current estimates predict that there are only about 30,000 or so TIS in the human genome, giving an imbalance ratio of about 1:3500 for TIS ATG vs. non-TIS ATG sites. Algorithms that are designed using datasets that have low imbalance ratio may not be well suited to predict TIS at the genomic level. In this paper, we modified the SVM algorithm that can handle moderately high imbalance ratio. The F-measures for other approaches were: Linear Discriminant 0%, SVM with under-sampling 4.1%, SVM with over-sampling 8.2%, Neural Network 13.3%, Decision Tree 20%, our approach 44%. This shows how poorly standard approaches perform at the genomic level due to the high imbalance ratio. Our approach improves the performance significantly. © 2005 IEEE.

Software architects have techniques to deal with many quality attributes such as performance, reliability, and maintainability. Usability, however, has traditionally been concerned primarily with presentation and not been a concern of software architects beyond separating the user interface from the remainder of the application. In this paper, we introduce usability-supporting architectural patterns. Each pattern describes a usability concern that is not supported by separation alone. For each concern, a usability-supporting architectural pattern provides the forces from the characteristics of the task and environment, the human, and the state of the software to motivate an implementation independent solution cast in terms of the responsibilities that must be fulfilled to satisfy the forces. Furthermore, each pattern includes a sample solution implemented in the context of an overriding separation based pattern such as J2EE Model View Controller. © IFIP International Federation for Information Processing 2005.

It has become increasingly common for websites and computer media to provide computer generated visual images, called avatars, to represent users and bots during online interactions. In this study, participants (N=255) evaluated a series of avatars in a static context in terms of their androgyny, anthropomorphism, credibility, homophily, attraction, and the likelihood they would choose them during an interaction. The responses to the images were consistent with what would be predicted by uncertainty reduction theory. The results show that the masculinity or femininity (lack of androgyny) of an avatar, as well as anthropomorphism, significantly influence perceptions of avatars. Further, more anthropomorphic avatars were perceived to be more attractive and credible, and people were more likely to choose to be represented by them. Participants reported masculine avatars as less attractive than feminine avatars, and most people reported a preference for human avatars that matched their gender. Practical and theoretical implications of these results for users, designers, and researchers of avatars are discussed. © 2005 Journal of computer-Mediated Communication.

Home service robots have received much attention from both academia and industry because home service robots have wide range of potential applications such as home security, cleaning, etc. The robots need to add or update services frequently according to the changing needs of human users. Furthermore, reactive nature of the robots add complexity to develop robot applications. These challenges raise safety issues seriously. Considering that safe operation of home service robots is crucial, current practice of validating robot applications is, however, not mature enough for wide deployment of home service robots. In this paper, we present our experience of developing and formally verifying discrete control software of Samsung Home Robot (SHR) using Esterel. We give a brief background on Esterel, then illuminate our result in formally verifying stopping behavior of SHR. Through the verification, we could detect and solve a feature interaction problem which caused the robot not to stop when a user commanded the robot to stop. © 2005 IEEE.

In this paper, the boundary value analysis method for testing case design is generalized for input parameters with constraints. We introduce the definition of priority levels to classify testing cases into three categories. With three input parameters X, Y and Z, we make the general assumptions of Y is a function of X (Y = f(X)) and Z is a function of X and Y (Z = g(X, Y)). The sequence algorithms for test case design are presented and an autogenerator based on the new algorithm is also developed. As a test to the auto-generator, output from the sample runs to NetProvision Activator (NPA), a real world product, is presented and analyzed.

This paper describes Mocha, an open mobile S/W platform and application developed by Samsung Electronics. Mocha's key features are its efficiency (it fits in regular phones), its portability (it covers different stack/OS/chipsets for CDMA, EV-DO, GSM/GPRS, and UMTS), its modularity and configurability (it meets customers' varying needs), its extensibility (it can be adapted to include new features and interfaces), its interoperability based on de-facto standards such as OMA, 3GPP, 3GPP2, CDG;and its security (it can withstand the attack of malicious applications). Among these key features, in this paper, we outline the multimedia messaging service (MMS) that inspired this system and then describe its design, architecture, and prototype implementation. © 2004 IEEE.

International Conference on Coordinated and Multiple Views in Exploratory Visualization

It is a common task when analyzing a large dataset (e.g., census database) to create some kind of overview of the original dataset, which is small enough to be easily manipulated, while remains the key characteristics of the data. Many aggregation techniques have been proposed to help users better understand the dataset and find desired information in it. However, the user can easily get lost after several aggregation operations, since there is rarely mechanism facilitating the user to remember what he or she has done in previous steps. In this paper, we present a prototype, namely MUSA, for multiple-step aggregation visualization. We aimed at designing a tool not only to help users obtain various levels of overviews to narrow their selections, but also to effectively visualize the aggregation processes to enhance the context awareness. We also conducted an informal user study to evaluate the tool.

International Conference and Workshop on Engineering of computer-Based Systems

Software development can be thought of as the evolution of abstract requirements into a concrete software system. The evolution, achieved through a successive series of elaborations and refinements, is inherently a complex process. The complexity is not merely in the product - the complexity of managing the evolution of the product throughout the life of a project is proportional to the size and complexity of the product. Managing software project teams is a complex task complicated by the distribution of project teams. Distributed collaboration requires adequate support for team coordination and risk management. human-computer interaction (HCI) combines technical concerns with human psychological concerns. Similarly, software project managers confront complexities in both of these dimensions. In this paper, we report on a collaborative design environment called LINK-UP being developed to guide the design process and facilitate reuse, We examine some Web-based project management tools in terms of their support for collaborative design and virtual team processes. We present a notification system approach to making the design record a natural by-product of the design process and a lever for knowledge reuse. Knowledge from past projects could then be used to automatically notify project teams of potential problems and suggest possible solutions.

Dynapad is a development environment designed to support research prototyping of multiscale workspaces. In this paper we describe applications designed to facilitate visual access to and spatial organization of digital photo collections and personal libraries of PDF documents. The research objective is to explore a generalization of the notion of a "pile" as a foundation for a versatile suite of tools to provide unobtrusive assistance for organizing collections and other sensemaking activities. We detail the architecture underlying the applications, explain how it supports diverse functionality and interaction styles, and abstract a set of principles for designing spatial tools.

This paper presents a multimodal interaction framework for semantic 3D object manipulation in the virtual reality. In our framework, interaction devices such as keyboard, mouse, joystick, tracker, can be combined with speech utterance to give a command to the system. We define an object ontology based on common sense knowledge which defines relationships between virtual objects. By taking into account the current user context and the object ontology, semantic integration component integrates the interpretation result from input manager, and then sends the result to the interaction manager. That result will be mapped into a proper object manipulation. Thus, the system can understand the user intention and assist him for achieving his goal in the handling process, instead of relying entirely on the user's control upon the interaction device and the object, avoiding nonsensical manipulations.
