Abstract:
“At resale stores I have seen brand new clothes with original price tag
still hanging from the sleeve. Some children have so many toys that they stay
frustrated, not knowing which one to pick up for their next amusement.
Presumably sensible adults trade in perfectly good cars just to have something
shinier and newer. Didn’t us once live productive normal lives, without all
these gadgets” [Cunningham (2005)]. During late eighties, nearly forty four
percent of the participants, who took part in a consumer survey conducted in
the US, responded positively to the question “My closets are filled with still
2
unopened items” [Faber and O’Guinn (1988)]. Reading such excerpts does not
greatly surprise us anymore; as such reports have become common now. For
many people shopping has moved beyond something that caters to their needs
and wants and has become a hobby [Cunningham (2005)], an activity that they
engage in to satisfy their hedonistic or pleasure-seeking goals [Ramnathan and
Menon(2006), O’Cass and McEween (2004), Faber and O’Guinn (1989)].
Others look at their new possession as something that fills a void in their lives
[Belk (1985), Diener et al. (1993)].

Abstract:
The main objective of the study is primarily to determine the magnitude of selected trace elements, the concentrations of which would possibly accelerate growth resulting in larger biomass and sustained period of exponential phase for economically viable harvest. The study on the effect of three trace elements namely Cu, Mn and Zn on two species of algae,ISOChrySiS galbana Parke and Synechocystib salina Wislouch under different conditions of salinity, PH and temperature involves several combinations for each metal, from which the relative set of conditions has been adduced. The scheme of the experiments was statistically designed for interpretation of data and factors were assessed and graded according to relative importance. The methodology adopted for data interpretation is analysis of variance by split-plot design method.
The thesis has been divided into five chapters. The introductory chapter explains the relevance of the research work undertaken. Chapter 11 gives a review on the work pertaining to the above mentioned three trace elements in relation to nutrition as well as on the toxic aspects about which there is an abundance of literature. Chapter Ill presents a detailed description of the material and specialised methods followed for the study. The results and conclusions of the various experiments on effect of metals on growth and other physiological activities are discussed in Chapters IV and V.

Abstract:
In wireless sensor networks, the routing
algorithms currently available assume that the sensor nodes are
stationary. Therefore when mobility modulation is applied to the
wireless sensor networks, most of the current routing algorithms
suffer from performance degradation. The path breaks in mobile
wireless networks are due to the movement of mobile nodes, node
failure, channel fading and shadowing. It is desirable to deal with
dynamic topology changes with optimal effort in terms of
resource and channel utilization. As the nodes in wireless sensor
medium make use of wireless broadcast to communicate, it is
possible to make use of neighboring node information to recover
from path failure. Cooperation among the neighboring nodes
plays an important role in the context of routing among the
mobile nodes. This paper proposes an enhancement to an existing
protocol for accommodating node mobility through neighboring
node information while keeping the utilization of resources to a
minimum.

Abstract:
The modern telecommunication industry demands higher capacity networks with high data rate. Orthogonal frequency division multiplexing (OFDM) is a promising technique for high data rate wireless communications at reasonable complexity in wireless channels. OFDM has been adopted for many types of wireless systems like wireless local area networks such as IEEE 802.11a, and digital audio/video broadcasting (DAB/DVB). The proposed research focuses on a concatenated coding scheme that improve the performance of OFDM based wireless communications. It uses a Redundant Residue Number System (RRNS) code as the outer code and a convolutional code as the inner code. The bit error rate (BER) performances of the proposed system under different channel conditions are investigated. These include the effect of additive white Gaussian noise (AWGN), multipath delay spread, peak power clipping and frame start synchronization error. The simulation results show that the proposed RRNS-Convolutional concatenated coding (RCCC) scheme provides significant improvement in the system performance by exploiting the inherent properties of RRNS.

ABSTRACT: Rubber seed oil was used as a multipurpose ingredient in natural rubber
(NR) and styrene butadiene rubber (SBR) compounds. The study shows that the oil,
when substituted for conventional plasticiser, imparts excellent mechanical properties
to NR and SBR vulcanizates. Further, it also improves aging resistance, reduces cure
time, increases abrasion resistance and flex resistance, and reduces blooming.

Abstract:
Rubber solutions were prepared and used for bonding wood pieces. The
effect of the variation of chlorinated natural rubber (CNR) and phenolformaldehyde
(PF) resin in the adhesive solutions on lap shear strength was determined. Natural
rubber and neoprene-based adhesive solutions were compared for their lap shear
strength. The storage stability of the adhesive prepared was determined. The change
in lap shear strength before and after being placed in cold water, hot water, acid,
and alkali was tested. The bonding character of these adhesives was compared with
different commercially available solution adhesives. The room-temperature aging
resistance of wood joints was also determined. In all the studies, the adhesive prepared
in the laboratory was found to be superior compared to the commercial adhesives.

Abstract:
Zeolite Y-encapsulated ruthenium(III) complexes of Schiff bases derived from 3-hydroxyquinoxaline-2-carboxaldehyde and 1,2-
phenylenediamine, 2-aminophenol, or 2-aminobenzimidazole (RuYqpd, RuYqap and RuYqab, respectively) and the Schiff bases derived from
salicylaldehyde and 1,2-phenylenediamine, 2-aminophenol, or 2-aminobenzimidazole (RuYsalpd, RuYsalap and RuYsalab, respectively) have
been prepared and characterized. These complexes, except RuYqpd, catalyze catechol oxidation by H2O2 selectively to 1,2,4-trihydroxybenzene.
RuYqpd is inactive. A comparative study of the initial rates and percentage conversion of the reaction was done in all cases. Turn over frequency
of the catalysts was also calculated. The catalytic activity of the complexes is in the order RuYqap > RuYqab for quinoxaline-based complexes and
RuYsalap > RuYsalpd > RuYsalab for salicylidene-based complexes. The reaction is believed to proceed through the formation of a Ru(V) species.
