This paper presents an approach to estimate the number of obsolete desktop and notebook computers and the quantity of various toxic components to be generated from these computers in the next ten to 15 years in India. This study indicates that with favourable government policies it will take 30 years more to achieve a computer penetration rate of 1 per capita. Long term equilibrium in computer penetration rate of 1.026 per capita in India will be achieved in next 32 years. Our results show that, 126 million units of desktop computers and 900 million units of notebook computers are expected to become obsolete by the end of year 2025. These results will help waste management authorities in planning appropriate infrastructure and facilities for handling, recycling and disposal of this hazardous waste. PC recycling capacity of approximately 1,045 million PCs is required by year 2020. This analysis does not address distribution of obsolete computers for reuse, recycling and landfill options nor their storage time, which is an important issue to resolve in the future.

This paper presents the design and implement a basic five stage pipelined MIPS-32 CPU. Particular attention will be paid to the reduction of clock cycles for lower instruction latency as well as taking advantage of high-speed components in an attempt to reach a clock speed of at least 100 MHz. The final results allowed the CPU to be run at over 200 MHz with a very reasonable chip area of around 900,000 nm2. © Research India Publications.

In this paper, we investigate the effect of channel spacing and chromatic dispersion on four wave mixing in WDM system. Dominating effect of four wave mixing is minimizing at maximum value of dispersion and channel spacing. Power of FWM, Q-factor, bit error rate and output spectrum is used to measure the performance of system. © 2015 by De Gruyter.

Induction cap sealing is a complex process. Through nonuniform spatial distribution of power over fine annular ring on thin foil, it not only ensures tamper proof sealing of container lip but also removes wax from the top surface of foil. The indirectly controlled sealing process does not have any feedback to execute any corrective measures. Traditionally, sealing operation is dominantly performed by induction effect and wax removal is by thermal conduction. Due to inferior heat conduction features, the sealing quality degrades if large thin foil is used. Therefore, modern cap sealing process needs to be dominantly controlled (both sealing and wax removal) by induction heating through the use of multiple heat sources over the foil surface to reduce the role of thermal conduction. In this paper, the controlled multizone heating is effectively implemented through proper coil design. The coil is fed by single-resonant inverter. © 2016 IEEE.

Stretchable electronics may open new applications in display, sensors and actuators. To attain the stretchable electronics, the ink formulation should be compatible with elastomeric substrates. Here, we present the formulation of silver nanoparticles and single walled carbon nanotubes (SWNTs) for printing stretchable silver electrodes on the elastomeric substrates. Highly conductive stretchable electrodes can be printed directly on the poly(styrene-b-butadiene- b-styrene) (PSBS) substrates by roll to plate (R2P) gravure printer. During the stretching test, R2P printed silver based stretchable electrodes show the high conductivity of 1000 S cm-1 at 0.27 wt% of SWNT loading. Furthermore, the resistance of the printed silver electrode was not changed up to 15% of tensile strain. Copyright © 2013 American Scientific Publishers All rights reserved.

Gold nanoclusters (AuNCs) have gained interest during the recent years because of their low toxicity and finer size for the bioimaging and biolabeling applications in comparison to the semiconductor quantum dot analogues. Diverse materials such as sulfur compounds, peptides, dendrimers, proteins, etc., are exploited for the preparation of AuNCs. Henceforth, highly fluorescent, water-soluble, and few atom-containing gold nanoclusters are created using a rapid, straightforward, and green method. In this regard for the first time chicken egg white (CEW), one of the most unique materials, is utilized in an aqueous solution under basic conditions at physiological temperature for the preparation of AuNCs. Tyrosine and tryptophan amino acid residues are responsible for the conversion of Au ions to Au0 under alkaline condtions. CEW contains four major proteins of which the main constituent protein, ovalbumin also leads to the formation of the AuNCs with a higher fluorescence emission compared to the CEW. The ratios between the different reaction partners are very crucial, along with temperature and time for the preparation of AuNCs with high photoluminescence emission. The limited vibrational motion of the proteins under alkaline condition and the bulkiness of the proteins help in the formation of AuNCs. © 2013 Elsevier B.V.

With recent advances in the technology of big data, many service providers have been trying to derive meaningful contexts from such data. Context-aware services can offer high quality service from the consumer's perspective, since most services are used in varying contexts and environments. The results from many studies on adaptive user interface have shown that context-aware user interfaces can be faster and preferable to non-adaptive counterparts. In this paper, we propose a novel framework providing a context adaptive user interface which automatically chooses appropriate Resources from a UI Page-Set consisting of multiple Resources. The proposed framework aimed to provide service directors who are not knowledgeable about UI development with opportunities for making context-aware UI, and to achieve high-quality user experience in complex services. © 2015 SERSC.
