Speech Title: Real Time Radioactive Materials Dispersion after Severe Nuclear Accident
  Speech Abstract: This study investigates the effects of atmospheric stability on the air, heat, and pollutant transport within the urban roughness sublayer by a validated 3-D RANS code. For better representing the real urban environment and characterizing the complex interactions between the roughness elements and the flow regimes, a building morphology with height variance is proposed. This design enables a stronger lateral momentum towards the target street canyon, which suppresses the spanwise dispersion of pollutants. Then, the stability of thermal stratification subject to the ground-inflow temperature difference is extended to span from strongly unstable to moderate stable. The quantitative indicators, including air exchange rate, heat removal rate, pollutant removal rate, heat transfer coefficient, and pollutant transfer coefficient, are introduced and analyzed. The correlations between indicators and thermal stabilities are established, which provides explicit expressions to describe the influence of the changing bulk Richardson number (Rb). The discussions on heat and pollutant transport based on stability categories show a high Rb-dependence of heat/mass transfer efficiency. The stability threshold is demonstrated to be Rb ≈ 0.7, where the flow speed near the ground is close to zero. As a result, the high temperature gradient is formed and acts as positive feedback to facilitate a more stratified condition. The data provided in the present study help achieve a better and environmentally friendly urban design.

Department of Computer Science, The University of Agriculture Peshawar, Pakistan

Speech Title: Comprehensive Improvements in Agri-Informatics Semantics
  Speech Abstract: Informatics play a vital role in nearly all areas of Agricultural Sciences. Advent in Information Technology re-innovate all sectors of Bio-Sciences.
  World Wide Web is the hub of all research resources. Researchers overcome tedious task of finding relevant and quality stuff through improved web searching, mining and integration.
  The main focus of this Research is to improve the Semantics of all Agricultural Sciences sub-disciplines or sub-domains. Semantics is improved through ontology engineering of any domain. Developed ontologies will be uploaded to existing standardized and approved biomedical repositories. The whole research team is specifically trying to establish our own W3C approved and standard ontology repository. In the first phase biotechnology and Plant Production Ontologies will be developed or improved.
  Outcome based Research and Transformation style of expertise sharing will be ensured. The main focus of the intended Research is also to train and equip students with relevant skills and expertise. Need based and market oriented training and professional grooming is a tangible asset for students.
  Expertise Ontology developers can also earn through freelancing. How to cope with job market challenges in this specialized area across the globe. Relevant training to Agriculture side students is very rare. They are used to all research vocabularies and terminologies in their area, but don’t know how to contribute their expertise to improve the efficiency of Semantic Web.
Biography: Dr. Muhammad Ishaq is a Member (M) of several research societies in the relevant discipline. Currently working as a senior Academician (Computer Science/IT) in Agriculture University Peshawar. Earned Ph.D. Computer Science in 2012 from Harbin Engineering University China. Active Researcher in the field of Bioinformatics, Agri-Informatics, Semantic Sciences and Ontology since 2006. Beside publication, projects, review services and conference presentations, he also delivers plenary in National and International conferences. He remains as a Chair/organizer of Research events and Conference Sessions.
