Human beings are the most intelligent among the creatures of the Earth. That is what they believe. However, they are only part of the system, and not the centre. Every creature has its own value and position in the system. Human activities often forget this fact. The Plant Patent was a tremendous step forward in the development of new cultivars for the benefit of the public. The "Peace‟ rose, was the single breakthrough that had maximum impact. Prom the Plant Patent Act, other forms of breeders‟ rights was spawned worldwide, including our own Plant Variety Protection Act (PVPA). Proof of the success has been the increasing use and acceptance of plant patents and the lack of challenges to the act and plant patent litigation. The paper deals with origin and development PBRS, the objectives of the act, its authorities and the farmer‟s rights and penalties relating to that. The paper focuses on the future farmer‟s rights and how the interest of the public can be maintained.

For dewaxing in the investment casting process the use of microwave is steadily growing in industrial processes. The present work studies the possible influence of dewaxing on the wax properties in investment casting process using microwave oven. The wax blend made up of paraffin wax, microcrystalline wax, carnauba wax used in this work was prepared by melting in an oven equipped with a mineral oil bath. The chemical and structural stability of the wax were monitored throughout 10 dewaxing cycles, via various analyses, namely, linear shrinkage, volumetric shrinkage, hardness and roughness. The results showed that microwave dewaxing is viable, significantly decreasing the incorporation of dirt and water. The percentage of linear shrinkage and volumetric shrinkage is increasing gradually in each repeated cycle. The gradual change in linear shrinkage is less as compared to gradual change in volumetric shrinkage. The change in hardness is not following any pattern as it some times decreasing and some time increasing.
Key Words: Investment casting, wax blend, microwave oven, dewaxing, pattern properties.
The structural and optical properties of the CdS, Cd2x(CuIn)1-xS2 (CCIS) thin films, at x=0.2,heterojunction were studied in the present paper. The heterojunction films deposited successfully on glass slides using by the spray pyrolysis technique at 623K. The thin films CdS, CCIS and the heterojunction ITO/CdS/CCIS were characterized by using x-ray diffraction. This is to find the polycrystalline series of the CdS, and CCIS solid solution with many phases as a mixture of chalcopyrite and zinc blend. The CdS, and CCIS thin films have a grain size 35 nm, and 16 nm respectively. The surface morphology was characterized by using atomic force microscopy (AFM) technique. The optical properties of the prepared thin films were investigated by using a UV-VIS spectrophotometer in the wavelength of 300 nm to 1100 nm. The films, ITO, CdS, and CCIS show direct transition with optical energy gap (Eg) values 3.52, 2.42, and 1.7eV respectively. The optical transmission (T),absorption (A) andrefractive index (n) were also discussed .

Multiplier is one of the most important arithmetic unit in Microprocessors and DSPs and also a major source of power dissipation. Reducing the power dissipation of multipliers is a key to satisfy the overall power budget of various digital circuits and systems. this paper elaborates the array multiplier through different logic styles. The fundamental units to design a multiplier are adders. The various types of adders used in this paper are complementary MOS (CMOS) logic style, complementary pass- transistor (CPL) logic style, double-pass transistor (DPL) logic style and domino logic style. The main objective of our work is to calculate the average power, delay and PDP of 4x4 multipliers. The design of full adder for low power is obtained and the low power units are implemented on the array multiplier and the results are analyzed for better performance. The designs are done using TANNER S-EDIT tool and are simulated using T-SPICE. The multiplier architectures are designed using the three better above said full adders and the results are compared so that we can obtain a better multiplier design.

This research presents methods to reduce defectives due to dent defects in flexible printed circuits manufacturing process. The DMAIC phases of Six Sigma quality improvement approach were applied to solve the problem. It was found that the variables that statistically affect the dent problem were 1) method to polish stainless steel plate, 2) method to store stainless steel plate, 3) method to clean stainless steel plate, 4) fisheyes/ foreign matters in the TPX release film. The dent defects were reduced by 1) changing from dry polishing method to wet polishing method, 2) storing stainless steel plates on storing tables and covering them by dust protectors, 3) improving cleaning equipment, 4) determining the relationship between the diameter of fisheyes/foreign matters in the release film and the defective proportion to encourage quality improvement of the vender. After the improvement, the defective proportion due to dent defects was reduced from 947 DPPM to 442 DPPM or 53.3% reduction. This improvement decreased defective cost of 666,529 baht per year .

Biometrics are physical or behavioral characteristics that can be used for human identification. In this dissertation, we propose the ear as a biometric and investigate its potential with both 2D and 3D data.This work is the largest experimental investigation of ear biometrics to date. The data set used for this experiments contains 50 persons, each with images acquired on at least two different dates. Approaches considered include a ICP (―eigen-ear‖) approach with 2D intensity images and range images, a Hausdorff matching of edges from range images, and an ICA-based approach to matching the 3D data. This experimental results demonstrate that the ICA-based approach outperforms the other approaches at a statistically significant level. Furthermore, this will develop the first fully automated biometric system using 3D ear shape. It is a complete automatic system starting with a raw 3D image, through automated segmentation of the ear, and 3D shape matching for recognition. The automatic system achieves a rank-one recognition rate of 97.6% on a 50-subject dataset. This algorithm shows good scalability of recognition rate with size of dataset. The results suggest a strong potential for 3D ear shape as a biometric. However, some people have ears with recognizably different shapes. Experimental results with partial ear shape suggest that minor hair covering does not affect the performance substantially, but large hair covering will certainly reduce the recognition rate. This suggests that even in circumstances where the complete ear shape cannot be captured, partial shape has potential for recognition. This lends support for using ear shape as a biometric.

Today, computer networks and distributed software systems are pervasive. Thus, the idea of secure computing is paramount. Secure Computing means avoiding improper disclosure of private or sensitive information. Data stored on a computer or processed by software should be modified only through legitimate, verifiable channels. We should guard against outsiders performing denial-of-service (DoS) attacks. For computing to be trustworthy, each bit of data the system uses and each user that interacts with the system must be authentic and legitimate. Systems must keep records of their activities to permit later forensic analysis to trace security breaches or to aid in transaction disputes. This paper considers some of the facts why business need information security policies, procedures, technical measures used to prevent unauthorized access, alteration, theft or physical damages. The major threats to business come from insiders who usually have some system knowledge and trust level. Secondly, most protection schemes target outsiders because attackers might control resource assets. For example controlling broadband Internet machines, target files containing trade secrets, credit-card numbers. Various issues for information protection system, application vulnerabilities, Security analysis, social engineering and phishing have been discussed for the benefit of IT business

Micro turbine-generator is suitable for different distributed generation applications. Due to its high
speed, it is necessary to use a frequency converter to deliver the power at 50/60Hz. In this paper, application of
Matrix Converter as micro turbine-generator interface converter is addressed. In this way, the interface
converter becomes more compact due to omission of dc link capacitor (common in rectifier-inverter interface
structure). Also, it is shown by the simulation results that by using matrix converter, quality of the output
voltage is enhanced.
