Genetic Engineering of Field, Industrial and Pharmaceutical Crops

Ability to modify plants at the genomic level by advanced molecular technology has enhanced the scope of improvements in plant traits attempted earlier through conventional breeding methods. Techniques such as genetic transformation have opened new vistas whereby functional genes, not commonly present in a particular species can be added from other species. The traits incorporated into the genetically engineered plants in the beginning were confined to those governed by dominant genes, e.g. insecticide resistance and herbicide tolerance but advancements with time now also permit the transfer of complexly inherited traits such as drought and cold tolerance. Transgenic technology is also useful in understanding gene expression and metabolic pathways which can then be used to harness the full genomic potential of the plant. This review presents a narrative on development of transgenics and their use for the improvement of field, industrial and pharmaceuticals crops. In addition, discussions are made on current status on genetically modified crops, hurdles to genetic engineering, overcoming strategies and future scope.

MDA (Model-Driven Architecture) as a Software Industrialization Pattern: An Approach for a Pragmatic Software Factories

In this paper we show that the MDA can be considered as a software industrialization pattern (or a software factory). Nearly all industries today are haunted with how to reduce costs, improve quality, faster time-to-market and to maximize profits. These challenges are particularly relevant to the software industry, because it still lags behind other technology sectors as regards industrialization and the timely delivery of software products. Most software are still of poor quality, always finished after deadlines (most don’t finish at all), and are very labour intensive. Here, we discuss the MDA as an approach that may help solving at the same time both problems of industrialization and ever-changing software infrastructures. We propose a MDA Engine based on a real case study in an IT services company. It is a proposal for a framework to create custom MDA tools, based on XMI, XSLT and the Visitor Pattern.

Engineering Intelligent Racing Concepts Using Design Research Methods

The automotive seat market is positioned to significantly grow over the next five years. Research into how sensor implementation in every day driver cars can enhance driver wellness is becoming increasingly popular and visible in the automotive seat industry. However, in the competitive race car industry,?drivers prioritize driving ability over wellness. To further examine this phenomenon, the Human-Machine Interaction?Lab at the Georgia Institute of Technology took a unique approach to developing strong use cases for implementing sensor technology to improve driving ability for race car drivers by combining qualitative and quantitative research data obtained through modern design research and planning methodology. Following a process relying heavily on user-centered design methods, the authors developed a business case concept?for?a sensor-based seat accessory that acts as a competitive racer’s?driving coach?that is able to identify the mechanics of braking, turning, and accelerating through pressure sensors in the driver’s seat pan surface. This technology allows drivers to precisely understand when and how hard to brake, turn, or accelerate out of turns, thus reducing heat times and financial burden for drivers.
