The purpose of this paper is to introduce and study the concepts of intuitionistic fuzzy weakly generalized closed set and intuitionistic fuzzy weakly generalized open set in intuitionistic fuzzy topological space. We investigate some of their properties. Also we study the application of intuitionistic fuzzy weakly generalized closed set namely(More)
Intact Lemna gibba plants were photoinhibited under anaerobic conditions on illumination with monochromatic light which selectively excited the photosystems. Photoinhibition was less when PS 1 was excited and greatest when mainly PS 2 was excited, which suggests that PS 2 was most damaged by photoinhibition induced in complete absence of O2 and CO2. The(More)
Tuberculosis is one of the most devastating bacterial diseases, with increasing rates of morbidity and mortality, despite the presence of effective chemotherapy and Bacillus-Calmette-Guerin (BCG) vaccine. The success of Mycobacterium tuberculosis lies in its ability to spread by aerosol droplets, evade the host immune system and to persist in pulmonary(More)
Aliquot watermarking is the unique idea in aliquot media for copyright protection. Various watermarking algorithm has been developed in recent years, but cognitive content of the intent, as they serve, they demarcated from each other. This context presents a new proposal for hiding a logo-based watermark in color still image. This dodge is based on(More)
Various watermarking algorithm has been developed in recent years. The two-dimension DCT and its counterpart Inverse 2-D DCT, are the most complex parts in the DCT-based watermarking systems. In this paper, the watermark to be inserted in the cover image is encrypted through a proposed encryption strategy to enhance the overall security instead of embedding(More)
With the rapid development and wide use of Internet, information transmission faces a big challenge of security. People need a safe and secured way to transmit information. Encryption is a common method, which is used for encrypting information. But it is easier to attract the attention of the attackers because the information cannot be read directly. The(More)
Breast cancer is the most prevalent disease and second leading cause of death among women in many countries. Mutations and consequent DNA damage in several genes such as oncogenes and tumour suppressor genes have been implicated with abnormal behavior of somatic cells, resulting into malignant growth termed cancer. DNA damage/changes in chromosomal DNA and(More)
Particle swarm optimization is the nature inspired computational search and optimization approach which was developed on the basis of behaviour of swarm. Recently each and every field of research is utilizing the properties of PSO. One of the popular field of research is image segmentation which is also fastest growing field. Taking the advantages of(More)
