IDEA: Interactive Display for Evolutionary Analyses
Amy Egan, Anup Mahurkar, Jonathan Crabtree, Jonathan H Badger, Jane M Carlton, Joana C Silva
BMC Bioinformatics , 2008, DOI: 10.1186/1471-2105-9-524
Abstract: We have developed IDEA (Interactive Display for Evolutionary Analyses), an intuitive graphical input and output interface which interacts with PHYLIP for phylogeny reconstruction and with codeml and baseml for molecular evolution analyses. IDEA's graphical input and visualization interfaces eliminate the need to edit and parse text input and output files, reducing the likelihood of errors and improving processing time. Further, its interactive output display gives the user immediate access to results. Finally, IDEA can process data in parallel on a local machine or computing grid, allowing genome-wide analyses to be completed quickly.IDEA provides a graphical user interface that allows the user to follow a codeml or baseml analysis from parameter input through to the exploration of results. Novel options streamline the analysis process, and post-analysis visualization of phylogenies, evolutionary rates and selective constraint along protein sequences simplifies the interpretation of results. The integration of these functions into a single tool eliminates the need for lengthy data handling and parsing, significantly expediting access to global patterns in the data.The estimation of substitution rates and selective constraints is an essential step in the study of fundamental questions in evolutionary biology, including the evolution and organization of genomes [1-3], and the genetic basis of species differences [4-6]. Estimation approaches based on maximum-likelihood (ML) provide highly accurate estimates of substitution rates and related variables of interest [7,8]. Arguably the most popular ML-based program for evaluating evolutionary hypotheses is PAML (Phylogenetic Analysis by Maximum Likelihood), and the two programs codeml and baseml are its core use cases [9]. codeml in particular allows the user to obtain estimates of substitution rates per branch and/or per site and to compare the likelihood of multiple models of molecular evolution given the data and a phyl

Asian Journal of Information Technology , 2012,
Abstract: Humans use the decimal code to represent numbers. Digital electronic circuits in computers and calculators use mostly the binary code Many other special codes are used in digital electronics to represent numbers, letters, punctuation marks and control characters. A common task of decoding from machine language to decimal numbers is encoding. A very common output device to encode English decimal numbers is the seven-segment display. In this study a 12-segment display is proposed for Arabic numeric characters display.

Advances in Human-Computer Interaction , 2013, DOI: 10.1155/2013/180192
Abstract: R&D in media-related technologies including multimedia, information retrieval, computer vision, and the semantic web is experimenting on a variety of computational tools that, if sufficiently matured, could support many novel activities that are not practiced today. Interactive technology demonstration systems produced typically at the end of their projects show great potential for taking advantage of technological possibilities. These demo systems or “demonstrators” are, even if crude or farfetched, a significant manifestation of the technologists’ visions in transforming emerging technologies into novel usage scenarios and applications. In this paper, we reflect on design processes and crucial design decisions made while designing some successful, web-based interactive demonstrators developed by the authors. We identify methodological issues in applying today’s requirement-driven usability engineering method to designing this type of novel applications and solicit a clearer distinction between designing mainstream applications and designing novel applications. More solution-oriented approaches leveraging design thinking are required, and more pragmatic evaluation criteria is needed that assess the role of the system in exploiting the technological possibilities to provoke further brainstorming and discussion. Such an approach will support a more efficient channelling of the technology-to-application transformation which are becoming increasingly crucial in today’s context of rich technological possibilities. 1. Introduction Technological advancements are at an unprecedented pace. Supported by ever-increasing computing power, storage capacity, network infrastructure, and scalability and further fuelled by the general public’s awareness of technology and their increasing willingness to try new services and the consequent marketing opportunities, many technology research laboratories around the world are fiercely investigating and experimenting on technological possibilities as never before. Multimedia, computer vision, information retrieval, artificial intelligence, and language technology are some examples of computational technology fields that are leading this advancement boom, promising a high-impact outcome that will shape the way we interact with technology as well as how we interact with each other in the coming years. In dominantly technically focused projects that have long been developed in these fields, the end of a project often sees a “demonstrator” or “demo system” that showcases possible end-user interactivity with the developed piece of
Designing 26-Segments Display for Bangla Characters
Mohammad Osiur Rahman,S.M. Lutful Kabir
Asian Journal of Information Technology , 2012,
Abstract: 18-segments display is normally used to display the entire alphabetic character of English. But there is no display unit for Bangla Alphabetic Characters. In this paper 26-segments display for Bangla alphabetic character has been proposed. From the review it appears that it is the first proposed display in the world for Bangla Alphabetic Character. Here a grid structure consisting of 26 segments has been discovered. All Bangla characters vowel and consonants can be characterized by using this grid structure. As there can be at least vowels (12), consonants (39), punctuation and some other symbols to be displayed, 6-bit inputs are used to represent each character. After analyzing which segments will be activated for which character, appropriate logic function and circuits have been derived in order to display each Bangla character.
