Beyond Music

Though the N918GB has been developed keeping music as the core element, the telephony aspect hasn’t been ignored. It is a 3G device and also boasts of Wi-Fi connectivity, which is rarely provided on a music phone. The 2 megapixel camera is decent though we have seen better onboard cameras. The battery backup is impressive and it managed to see us through two days with around two hours of internet browsing and almost four hours of music playback.

However, keeping the Bluetooth turned on and using a pair of stereo Bluetooth turned headsets to listen to music cuts the backup by half, which is understandable.

The N91 8GB would score over Sony Ericsson’s W950i in terms of its internal memory and onboard camera.

R&D in energy is critical to realise this ambitious target and thus meet development goals. Given the difficulties in procuring fossil fuel supplies, there is a need to direct R&D to more efficient way of distribution and consumption, development of substitutes to fossil fuels and adopting commercial low carbon high-efficiency technologies that extract and use coal, our most abundant primary resource.

Apart from coal, there is need for a mission on bio-energy that would include bio-diesel from non-edible oils such as Jatropha and Karanj. On the other side, storage technology is important for using intermittent sources of power and for the automotive sector.

India’s theoretical solar power potential (600TWA) is several folds above its current total energy consumption. However, much needs to be done to develop this into cheap energy. The impediment here is high cost. There are interesting developments that could lead to big gains in thin films solar cells with the potential for nearly 45 percent sunlight-to-electricity conversion efficiency appears feasible through this route.

The overall efficiency of energy consumed is lost or wasted in the process of conversion from raw materials such as coal to the final energy services. In India, currently the total installed power generation capacity is 143,311 MW, derived as thermal power from coal, gas and oil(64.6 percent), hydro power (24.7percent) and as renewable energy (7.4percent). Nuclear energy component is still rather low (2.9 percent). To meet energy needs till 2032, at the very least, India needs to increase primary energy supply 3 to 4 times and electricity generation capacity/supply by 5 to 6 times of current levels. By 2032, power generation capacity must increase to nearly 800,000 MW from the current capacity of around 160,000MW.

Science and technology development as an engine of growth for India has several facets, some of which have been mentioned earlier. One Key element relates to the creation of the modern infrastructure. This includes, among other things, transportation systems, communication systems, power, and urban and rural infrastructure.

Each one of them poses unique challenge, not only in installation, commissioning and operation but also in research and development. These R&D efforts encompass very broad-spectrum of technologies and engineering endeavors. To give a flavor of the breadth and depth of such challenging demands, we pick up energy as a case in point.

The demand for energy has grown enormously since the middle of the last century. As world population grew 3.2 times between 1850 and 1970, precipitate use of industrial energy grew nearly 20-fold. Due to fast depletion, increasing cost and environment issues with fossil fuels, alternative and renewable sources of energy have become important.

Total energy use is skewed towards the developed world. Though per capita commercial energy consumption in low income countries has more than doubled, 15 percent of the world’s population in the industrialized nations consume over half the energy produced.

Technology has advanced more in the last half a century than in the previous 2,000 years. History has shown that modern economic growth has been inspired by a rapid and persistent upgrading of technology and scientific know-how. One third to half the growth of the industrially advanced countries is estimated to have come from technological prgress.

Unlike invention, innovation consists of practical application of invention. Innovation is essentially the task of the entrepreneur. And India is on the way to becoming a major player in global innovation. This in turn implies adoption of technology foresight to make the right technology choices with a national perspective; establish a robust innovation ecosystem; and leverage international cooperation to reinforce our own innovative strategies.

India is already displaying its innovative capabilities in manufacturing, bio-technology and even at the grassroots level. A dramatic recent example is the Tata Nano, which through innovations in design, engineering and manufacturing has created the world’s first low-cost, mass-produced car. The real benefit of India’s scientific and technological talent pool is not just in terms of scalability, high-levels skills and comparatively low-costs, but in its innovative capabilities.

Selecting the Most Appropriate Data Type

Choosing the data type best suited to the values you expect to enter into the Corresponding field is extremely important. When making this decision, take into account the following factors:

The range and type of values that the field will hold
The types of calculations you expect to perform on those values
The manner in which the data is to be formatted for display purposes
The manner in which the data is to be sorted and compared against other fields
The available subtypes for each field and their storage efficiencies

By taking all these factors into consideration at the time of designing your database, you reduce the chance of incompatibilities and storage inefficiencies later. Using the wrong data type can affect both the performance of your RDBMS and the types of operations you can perform on that field. For example, using a VARCHAR type on a field that is meant for numeric or date values could result in unexpected behavior when you perform calculations on it, just as using a large TEXT field for small string values could lead to a waste of space and inefficient indexing.
