Over the past decade Video and Image data is accumulated in the storage media of various commercial organizations, government and educational Institutions. Events are organized round the year in these organizations and are recorded through the digital devices installed at the event venues. Eventually the data is piled up in the electronic vaults and the end-users are unaware of the implications...

In collaboration with the Armed Forces Institute of Pathology's Department of Defense DNA Registry, the National Institute of Standards and Technology recently evaluated the performance of a short tandem repeat multiplex with dried whole blood stains on four different commercially available identification card matrixes. DNA from 70 stains that had been stored for 19 months at ambient temperatur...

We show a simple, robust, chemical route to the fabrication of ultrahigh-density arrays of nanopores with high aspect ratios using the equilibrium self-assembled morphology of asymmetric diblock copolymers. The dimensions and lateral density of the array are determined by segmental interactions and the copolymer molecular weight. Through direct current electrodeposition, we fabricated vertical ...

A techno-economic model was developed to investigate the influence of components on the system costs of redox flow batteries. Sensitivity analyses were carried out based on an example of a 10 kW/120 kWh vanadium redox flow battery system, and the costs of the individual components were analyzed. Particular consideration was given to the influence of the material costs and resistances of bipolar...

We begin with a review of the basic molecules responsible for the functioning of all organisms' cells. Much of the material here comes from the introductory textbooks by Drlica [2], Lewin [4], and Watson et al. [8]. Later in the course, when we discuss the computational aspects of molecular biology, some useful textbooks will be those by Gusfield [3], Salzberg et al. What sorts of molecules per...

Accurate and reliable hydrogen sensors are an important enabling technology for the large-scale introduction of hydrogen as a fuel or energy storage medium. As an example, in a hydrogen-powered fuel cell car of the type now introduced to the market, more than 15 hydrogen sensors are required for safe operation. To enable the long-term use of plasmonic sensors in this particular context, we intr...

Arrays of atoms trapped in optical lattices are appealing as storage media for photons, since motional dephasing of the atoms is eliminated. The regular lattice is also associated with band structure in the dispersion experienced by incident photons. Here we study the influence of this band structure on the efficiency of quantum memories based on electromagnetically induced transparency (EIT) a...

Digital forensics is the science of identifying, extracting, analysing and presenting the digital evidence that has been stored in the digital devices. Various digital tools and techniques are being used to achieve this. Our paper explains emerging cyber crimes, forensic analysis steps in the storage media, hidden data analysis in the file system, network forensic methods and cyber crime data m...

T he electronics industry employs millions of workers throughout the world and plays a significant role in the structure of the world’s economy. Many multinational electronics industries retain their capital intensive operations in home countries, but locate their labour intensive operations in newly industrialising countries, because of the lower cost of labour and attractive financial and inf...
