Abstract:
This thesis Entitled compensation to workmen for industrial injuries.Evaluation of the different forms of liability for compensating industrial injuries makes it evident that the liability under the social insurance scheme is the most befitting one, as it eliminates the problem of evasion of liability by the employer by providing for sharing of liability. Liability for compensation under the workmen's Compensation Act, 1923 and the Employees' State Insurance Act, 1948 arises only in the case of accidents, arising in the course of and out of employment. Majority of the workers, covered by the workmen's Compensation Act, have supported lumpsum payment of compensation under the Act. It appears that workers are ignorant of the cemerits of lumpsum payment. So, the workers should be properly educated by the Inspectorate, proposed above, about the comparative advantages of periodical payments. It is suggested that the workmens Compensation Act, 1923 may be amended, imposing fee upon the parties for each adjournment. It is also suggested that provision may be made in the workmens Compensation Act, 1923 for the expeditious despatch of amendments of the Workmen's Compensation Act, 1923, the Workmens· Compensation Rules, 1924 and the Schedules, made from time to time, to the comrnissioners for workmens Compensation, This will help them mete out justice to an injured workman, as required by the changes in the law. The Employees' State Insurance Act, 1948 and the Rules may be amended, requiring the employers to provide the employees with necessary information, in the vernacular language, about the employment injury benefits available under the Employees' State Insurance Act, 1948 and the formalities for obtaining the same. This will help the illiterate employees, especially the casual ones, avail of employment injury benefits. Changes in the law, on the lines suggested above, are imperative to make the system of compensation for industrial injuries prove effective and beneficial to injured workmen.

Bank switching in embedded processors having partitioned memory architecture results in code size as well as run time overhead. An algorithm and its application to assist the compiler in eliminating the redundant bank switching codes introduced and deciding the optimum data allocation to banked memory is presented in this work. A relation matrix formed for the memory bank state transition corresponding to each bank selection instruction is used for the detection of redundant codes. Data allocation to memory is done by considering all possible permutation of memory banks and combination of data. The compiler output corresponding to each data mapping scheme is subjected to a static machine code analysis which identifies the one with minimum number of bank switching codes. Even though the method is compiler independent, the algorithm utilizes certain architectural features of the target processor. A prototype based on PIC 16F87X microcontrollers is described. This method scales well into larger number of memory blocks and other architectures so that high performance compilers can integrate this technique for efficient code generation. The technique is illustrated with an example

Abstract:
This paper reports the synthesis of a series of six new polystyrene anchored metal complexes of Co(II), Fe(III), Ni(II),
Cu(II), Zn(II), and dioxouanium(VI) using the polystyrene anchored Schiff base of 2-nitrobenzaldehyde and the corresponding
metal salts. The metal salts used were anhydrous FeCl3, CoCl2 Æ 6H2O, Ni(CH3COO)2 Æ 4H2O, Cu(CH3-
COO)2 Æ H2O, Zn(CH3COO)2 Æ 2H2O, and UO2(CH3COO) Æ 2H2O. Physico chemical characterizations have been made
from diffuse reflectance and vibrational spectra, elemental analysis, magnetic measurements, and TG studies. The elemental
analysis suggest a 1:2 metal:ligand ratio when the complexation has carried out at 70 C for about 12 h reflux. The
ligand is monodentate and coordinates through the azomethine nitrogen. The Fe(III), Co(II), Ni(II), and Cu(II) complexes
are all paramagnetic whereas Zn(II) and U(VI) are diamagnetic. Zn(II) is assigned a tetrahedral structure, Cu(II) and
Co(II) are assigned a square planar structure and Fe(III), Ni(II), and U(VI) are all assigned an octahedral structure.
The polystyrene anchored ligand has been developed as an excellent reagent for the removal of Cu(II). Optimum conditions
have been developed for the removal of metal ion from solutions by studying the effect of change of concentration of
metal ion, ligand, effect of pH, time of reflux, and interference effect of other ions. It was found that within a span of 20 min
it is possible to remove 90% of the metal ion from a 30 ppm metal ion solution in the pH range 4–5.5.

Abstract:
n this paper, a time series complexity analysis of dense array electroencephalogram signals is carried out using the recently introduced Sample Entropy (SampEn) measure. This statistic quantifies the regularity in signals recorded from systems that can vary from the purely deterministic to purely stochastic realm. The present analysis is conducted with an objective of gaining insight into complexity variations related to changing brain dynamics for EEG recorded from the three cases of passive, eyes closed condition, a mental arithmetic task and the same mental task carried out after a physical exertion task. It is observed that the statistic is a robust quantifier of complexity suited for short physiological signals such as the EEG and it points to the specific brain regions that exhibit lowered complexity during the mental task state as compared to a passive, relaxed state. In the case of mental tasks carried out before and after the performance of a physical exercise, the statistic can detect the variations brought in by the intermediate fatigue inducing exercise period. This enhances its utility in detecting subtle changes in the brain state that can find wider scope for applications in EEG based brain studies.

Abstract:
A new polymer matrix sensitized with methylene blue for use as an optical recording material is described
here. The characterization is done to determine the optimal recording conditions. These films need no
chemical development and are found to be stable for several months. The matrix has excellent shelf life
and needs an exposure only as short as 20 s. Direct imaging was done on this material.

Abstract:
Dielectric properties of polyaniline at different frequencies were studied. Cavity perturbation technique was employed for the
study. Poly aniline in the powder and pelletised forms were prepared under different environmental conditions. Different samples of
poly aniline exhibit high conductivity. However. the conductivity of samples prepared under different environmental conditions is
found to vary. All the samples in the powder form have high conductivity irrespective of the method of preparation. The high
conductivity at microwave frequency makes it possible to be used for developing microwave components like filters.

The room temperature AC conductivity σ(ω) of amorphous AsSe samples with various compositions have been measured in the 103 -106 Hz frequency range. The results indicate that ac conductivity is proportional to n with n=0.89±.01 in the 103 –106 Hz frequency range. Consideration of different models for the frequency –dependent conductivity leads to thermally activated hopping as the most likely process

Abstract:
Sign language is the primary means of communication for the hard to
hear and speak people around the globe. Sign language emphasizes on visual
possibilities as the participants are unable to hear sound patterns. Sign language
uses different signs, body postures and gestures as opposed to sound patterns
for communication, and evolves like any other spoken language. American
Sign Language (ASL), British sign language (BSL), Arabic sign language
(ArSL), Chinese sign language (CSL) and Indian sign language (ISL) are some
of the widely used sign language systems around the world. There exists
significant variation between sign languages, and due to these inherent
variations, it is not possible to fully adopt a methodology that is found suitable
for all. There are enormous complexities in ISL. Contrary to ASL, ISL
sentences follow Subject-Object-Verb pattern. For example, the relative
positioning of hand on face with respect to nose can convey ‘WOMAN’ or
‘THINK’ in ISL. Such complexities necessitate independent research in ISL.
Sign language recognition involves integration of different categories
of signs. The signs can be mainly categorized into three groups like static hand
gestures, dynamic gestures and facial expression. This research focuses on
these three different channels and work to identify the potential of different
computational methods to address some of the associated complexities with
each channel. These complexities include static gestures with resemblances,
static overlaid gestures, differential movement and directional changes in
dynamic gestures and facial expression changes.
We propose a novel, simple, efficient and distribution-free re-sampling technique for developing prediction intervals for returns and volatilities following ARCH/GARCH models. In particular, our key idea is to employ a Box–Jenkins linear representation of an ARCH/GARCH equation and then to adapt a sieve bootstrap procedure to the nonlinear GARCH framework. Our simulation studies indicate that the new re-sampling method provides sharp and well calibrated prediction intervals for both returns and volatilities while reducing computational costs by up to 100 times, compared to other available re-sampling techniques for ARCH/GARCH models. The proposed procedure is illustrated by an application to Yen/U.S. dollar daily exchange rate data.

Abstract:
Thunderstorm is one of the most spectacular weather phenomena
in the atmosphere. Many parts over the Indian region experience
thunderstorms at higher frequency during pre-monsoon months (March-
May), when the atmosphere is highly unstable because of high
temperatures prevailing at lower levels. Most dominant feature of the
weather during the pre-monsoon season over the eastern Indo-Gangetic
plain and northeast India is the outburst of severe local convective
storms, commonly known as ‘Nor’wester’ or ‘Kalbaishakhi’. The severe
thunderstorms associated with thunder, squall line, lightning and hail
cause extensive losses in agriculture, damage to structure and also loss of
life. The casualty due to lightning associated with thunderstorms in this
region is the highest in the world. The highest numbers of aviation
hazards are reported during occurrence of these thunderstorms. In India,
72% of tornadoes are associated with this thunderstorm.

Abstract:
The application of computer vision based quality control has been slowly but steadily gaining importance mainly due to its speed in achieving results and also greatly due to its non- destnictive nature of testing. Besides, in food applications it also does not contribute to contamination. However, computer vision applications in quality control needs the application of an appropriate software for image analysis. Eventhough computer vision based quality control has several advantages, its application has limitations as to the type of work to be done, particularly so in the food industries. Selective applications, however, can be highly advantageous and very accurate.Computer vision based image analysis could be used in morphometric measurements of fish with the same accuracy as the existing conventional method. The method is non-destructive and non-contaminating thus providing anadvantage in seafood processing.The images could be stored in archives and retrieved at anytime to carry out morphometric studies for biologists.Computer vision and subsequent image analysis could be used in measurements of various food products to assess uniformity of size. One product namely cutlet and product ingredients namely coating materials such as bread crumbs and rava were selected for the study. Computer vision based image analysis was used in the measurements of length, width and area of cutlets. Also the width of coating materials like bread crumbs was measured.Computer imaging and subsequent image analysis can be very effectively used in quality evaluations of product ingredients in food processing. Measurement of width of coating materials could establish uniformity of particles or the lack of it. The application of image analysis in bacteriological work was also done

The median (antimedian) set of a profile π = (u1, . . . , uk) of vertices of a
graphG is the set of vertices x that minimize (maximize) the remoteness i d(x,ui ).
Two algorithms for median graphs G of complexity O(nidim(G)) are designed,
where n is the order and idim(G) the isometric dimension of G. The first algorithm computes median sets of profiles and will be in practice often faster than the other
algorithm which in addition computes antimedian sets and remoteness functions and
works in all partial cubes
