Abstract:
The study is undertaken by the researcher with the object of examining the remuneration pattern of executive personnel in the manufacturing public enterprises in Kerala so as to find out whether there is any rationale or criteria involved in remunerating executives. It is also envisaged to find out the pattern of executive remuneration in the various categories of industries and inter—industry disparities among the public sector enterprises. This is considered to be a very fruitful area for investigation, particularly in view of the generally prevailing notion that public sector executives in Kerala are not remunerated properly and glaring inequalities and disparities are existing among the various categories of industries and within the same industry. Therefore the study is to explore the criteria used for the determination of executive remuneration and the relative weightage of various factors such as size of the firm, rate of return sales volume etc of the organisation and various other factors such as qualification, experience, level of job and functions of executives. Further the study is extended to find out the role of 'pay' towards motivation and efficiency of the executive personnel

In this paper we investigate the problem of cache resolution in a mobile peer to peer ad hoc network. In our
vision cache resolution should satisfy the following requirements: (i) it should result in low message
overhead and (ii) the information should be retrieved with minimum delay. In this paper, we show that
these goals can be achieved by splitting the one hop neighbours in to two sets based on the transmission
range. The proposed approach reduces the number of messages flooded in to the network to find the
requested data. This scheme is fully distributed and comes at very low cost in terms of cache overhead. The
experimental results gives a promising result based on the metrics of studies.

This study shows that the disease resistance and survival
rate of Penaeus monodon in a larval rearing systems
can be enhanced by supplementing with antagonistic
or non-antagonistic probiotics. The antagonistic mode
of action of Pseudomonas MCCB 102 and MCCB 103
against vibrios was demonstrated in larval mesocosm
with cultures having su⁄cient concentration of antagonistic
compounds in their culture supernatant. Investigations
on the antagonistic properties of Bacillus
MCCB 101, Pseudomonas MCCB 102 and MCCB 103
and Arthrobacter MCCB 104 against Vibrio harveyi
MCCB111under in vitro conditions revealed that Pseudomonas
MCCB 102 and MCCB 103 were inhibitory to
the pathogen.These inhibitory propertieswere further
con¢rmed in the larval rearing systems of P. monodon.
All these four probionts signi¢cantly improved larval
survival in long-term treatments as well as when challengedwith
a pathogenic strain ofV. harveyiMCCB111.
We could demonstrate that Pseudomonas MCCB 102
andMCCB103 accorded disease resistance and a higher
survival rate in P. monodon larval rearing systems
throughactive antagonism of vibrios,whereas Bacillus
MCCB 101 and Arthrobacter MCCB 104 functioned as
probiotics through immunostimulatory and digestive
enzyme-supporting modes of action.

Abstract:
Decimal multiplication is an integral part of financial,
commercial, and internet-based computations. This paper
presents a novel double digit decimal multiplication
(DDDM) technique that performs 2 digit multiplications
simultaneously in one clock cycle. This design offers low
latency and high throughput. When multiplying two n-digit
operands to produce a 2n-digit product, the design has a
latency of (n / 2) 1 cycles. The paper presents area
and delay comparisons for 7-digit, 16-digit, 34-digit double
digit decimal multipliers on different families of Xilinx,
Altera, Actel and Quick Logic FPGAs. The multipliers
presented can be extended to support decimal floating-point
multiplication for IEEE P754 standard

Abstract:
Residue Number System (RNS) based Finite Impulse Response (FIR) digital filters and
traditional FIR filters. This research is motivated by the importance of an efficient filter
implementation for digital signal processing. The comparison is done in terms of speed and
area requirement for various filter specifications. RNS based FIR filters operate more than
three times faster and consumes only about 60% of the area than traditional filter when
number of filter taps is more than 32. The area for RNS filter is increasing at a lesser rate than that for traditional resulting in lower power consumption. RNS is a nonweighted number system without carry propogation between different residue digits.This enables simultaneous parallel processing on all the digits resulting in high speed addition and multiplication in the RNS domain

Abstract:
This paper presents a performance analysis of
reversible, fault tolerant VLSI implementations of carry select
and hybrid decimal adders suitable for multi-digit BCD
addition. The designs enable partial parallel processing of all
digits that perform high-speed addition in decimal domain.
When the number of digits is more than 25 the hybrid decimal
adder can operate 5 times faster than conventional decimal
adder using classical logic gates. The speed up factor of hybrid
adder increases above 10 when the number of decimal digits is
more than 25 for reversible logic implementation. Such highspeed
decimal adders find applications in real time processors
and internet-based applications. The implementations use only
reversible conservative Fredkin gates, which make it suitable for
VLSI circuits.

Abstract:
A sandwich construction is a special form of the laminated composite consisting of light weight core, sandwiched between two stiff thin
face sheets. Due to high stiffness to weight ratio, sandwich construction is widely adopted in aerospace industries. As a process dependent bonded
structure, the most severe defects associated with sandwich construction are debond (skin core bond failure) and dent (locally deformed skin
associated with core crushing). Reasons for debond may be attributed to initial manufacturing flaws or in service loads and dent can be caused by
tool drops or impacts by foreign objects. This paper presents an evaluation on the performance of honeycomb sandwich cantilever beam with the
presence of debond or dent, using layered finite element models. Dent is idealized by accounting core crushing in the core thickness along with the
eccentricity of the skin. Debond is idealized using multilaminate modeling at debond location with contact element between the laminates.
Vibration and buckling behavior of metallic honeycomb sandwich beam with and without damage are carried out. Buckling load factor, natural
frequency, mode shape and modal strain energy are evaluated using finite element package ANSYS 13.0. Study shows that debond affect the
performance of the structure more severely than dent. Reduction in the fundamental frequencies due to the presence of dent or debond is not
significant for the case considered. But the debond reduces the buckling load factor significantly. Dent of size 8-20% of core thickness shows 13%
reduction in buckling load capacity of the sandwich column. But debond of the same size reduced the buckling load capacity by about 90%. This
underscores the importance of detecting these damages in the initiation level itself to avoid catastrophic failures. Influence of the damages on
fundamental frequencies, mode shape and modal strain energy are examined. Effectiveness of these parameters as a damage detection tool for
sandwich structure is also assessed

Abstract:
The chaotic dynamics of directly modulated semiconductor lasers with delayed optoelectronic feedback is studied numerically. The effects of positive and negative delayed optoelectronic feedback in producing chaotic outputs from such lasers with nonlinear gain reduction in its optimum value range is investigated using bifurcation diagrams. The results are confirmed by calculating the Lyapunov exponents. A negative delayed optoelectronic feedback configuration is found to be more effective in inducing chaotic dynamics to such systems with nonlinear gain reduction factor in the practical value range.

Abstract:
Learning Disability (LD) is a classification including several disorders in which a child has difficulty in learning in a typical manner, usually caused by an unknown factor or factors. LD affects about 15% of children enrolled in schools. The prediction of learning disability is a complicated task since the identification of LD from diverse features or signs is a complicated problem. There is no cure for learning disabilities and they are life-long. The problems of children with specific learning disabilities have been a cause of concern to parents and teachers for some time. The aim of this paper is to develop a new algorithm for imputing missing values and to determine the significance of the missing value imputation method and dimensionality reduction method in the performance of fuzzy and neuro fuzzy classifiers with specific emphasis on prediction of learning disabilities in school age children. In the basic assessment method for prediction of LD, checklists are generally used and the data cases thus collected fully depends on the mood of children and may have also contain redundant as well as missing values. Therefore, in this study, we are proposing a new algorithm, viz. the correlation based new algorithm for imputing the missing values and Principal Component Analysis (PCA) for reducing the irrelevant attributes. After the study, it is found that, the preprocessing methods applied by us improves the quality of data and thereby increases the accuracy of the classifiers. The system is implemented in Math works Software Mat Lab 7.10. The results obtained from this study have illustrated that the developed missing value imputation method is very good contribution in prediction system and is capable of improving the performance of a classifier.

Abstract:
Mobile Ad-hoc Networks (MANETS) consists of a collection of mobile nodes without having a central
coordination. In MANET, node mobility and dynamic topology play an important role in the performance.
MANET provide a solution for network connection at anywhere and at any time. The major features of
MANET are quick set up, self organization and self maintenance. Routing is a major challenge in MANET
due to it’s dynamic topology and high mobility. Several routing algorithms have been developed for
routing. This paper studies the AODV protocol and how AODV is performed under multiple connections in
the network. Several issues have been identified. The bandwidth is recognized as the prominent factor
reducing the performance of the network. This paper gives an improvement of normal AODV for
simultaneous multiple connections under the consideration of bandwidth of node.
