In this article, an extreme environment-capable temperature sensing system based on state-of-art silicon carbide (SiC) wireless electronics is presented. In conjunction with a Pt-Pb thermocouple, the SiC wireless sensor suite is operable at 450 °C while under centrifugal load greater than 1,000 g. This SiC wireless temperature sensing system is designed to be non-intrusively embedded inside the...

The Adaptive Communication Environment (ACE) and The ACE ORB (TAO) are cutting edge, real-time software products that by nature support and grow from change. Therefore, eXtreme Programming (XP) would seem to be appropriate for these projects. In fact, their developers have been following many XP practices all along. We describe these practices here, and identify some that we do not follow rigor...

Agility is bringing in responsibility and ownership in individuals, which will eventually bring out effectiveness and efficiency in deliverables. Companies are drifting from traditional Software Development Life Cycle models to Agile Environment for the purpose of attaining quality and for the sake of saving cost and time. In Traditional models, life cycle is properly defined and also phases ar...

Big data analytics are rapidly becoming mainstream IT functions for organizations of all sizes. The ability to capture and analyze massive data sets is leading to opportunities both profound and mundane: from truly life-saving medical breakthroughs and disaster forecasting to fraud detection and improved business agility. Businesses recognize the impact this type of analysis can make, particula...

The Tinto River (Huelva, southwestern Spain) is an extreme environment with a rather constant acidic pH along the entire river and a high concentration of heavy metals. The extreme conditions of the Tinto ecosystem are generated by the metabolic activity of chemolithotrophic microorganisms thriving in the rich complex sulfides of the Iberian Pyrite Belt. Molecular ecology techniques were used t...

Searles Lake is a salt-saturated, alkaline brine unusually rich in the toxic element arsenic. Arsenic speciation changed from arsenate [As(V)] to arsenite [As(III)] with sediment depth. Incubated anoxic sediment slurries displayed dissimilatory As(V)-reductase activity that was markedly stimulated by H2 or sulfide, whereas aerobic slurries had rapid As(III)-oxidase activity. An anaerobic, extre...

Polymers with self-lubricating properties have been employed in various applications as bearing components and tribological surfaces, particularly where the use of liquid lubricant is infeasible, such space-related applications. This study reports on solutions for extreme temperature ranging from ?196 to 300 °C, which simulates operating conditions that materials space will encounter. Tribologi...
