 Abstract

In this paper, an effective unsupervised change detection technique using spatial fuzzy c- means clustering for VHR remote sensing images is proposed. First, the Gabor wavelets are used to attain the images at multiple scales and rotations, whose maximum magnitude over all rotations in each scale is integrated to form the Gabor feature vector. Then a GWDM image is generated. In GWDM, a local similarity measure MRF neighborhood system is incorporated to obtain the relationship between the neighborhood pixels. The coefficient of variation method is applied to differentiate contributions form different features. Next, spatial fuzzy c-means algorithm is incorporated to obtain changed and unchanged results. Finally, the proposed approach demonstrates the effectiveness in the change detection

 Abstract

LDPC codes are one of the hottest topics in coding theory today. Originally invented in the early 1960's, they have experienced an amazing comeback in the last few years. Unlike many other classes of codes LDPC codes are already equipped with very fast (probabilistic) encoding and decoding algorithms. The question is that of the design of the codes such that these algorithms can recover the original code word in the face of large amounts of noise. New analytic and combinatorial tools make it possible to solve the design problem. This makes LDPC codes not only attractive from a theoretical point of view, but also perfect for practical applications. Although an LDPC code is a block code it gives an exceptional BER performance nearly close to Shannon limit when compared to other block codes. This is due to the message passing decoding algorithm used in the LDPC decoder. LDPC codes also provide high code gain at low BER.

 Abstract

Ayurveda is recognized as foremost life science and describes ways to prevent and manage many diseases, the world is being attracted towards its potential. Ayurveda provides better solution in the forms of proper treatment, dietary management, lifestyle advises. The present time is the era of fast food, irregularities in daily meal-time, sedentary life style and mental stress. All these factors ultimately disturb the digestive system resulting in the manifestation of various diseases. Among them the Prevelance of Parinama Shoola is increasing day by day. Etymological derivation of shool is combination of Rujayam(dhatu)+k(prataya).Generally the term shula is commonly used for shira shula,kukshi shool, akshi shool etc. Parinaam shool has been described for the first time in Madhav Nsidan.The Main characterstic of parinama shool is the abdominal pain at the end of the digestion and suggest a pain predominant disease. It is related to the Annavaha srotas. The cardinal feature of this disease is Ahara jiryamana kala shoola.The site effected with parinaam shool is Grahni..Shool normally appear as rupa(symptom) or updrava. Parinama shool can be compared with Dueodenal ulcer.It deveiops in duodenum. It is the upper portion of the small intestine. Many type of ayurvedic formulation given in our texts. In which triphala is the best remedy for parinama shool. Which is given in chakradatta. A Pharmacological activity of Triphala (haritaki vibhataki aamlaki) is vatanulomk,pittashamak etc. Which is helpful in relieving the pain and cure the parinaam shool

 Abstract

This research paper projects the exploration of the female psyche in the novel, Ladies Coupe. Anita Nair is a prolific writer in Indian writing in English. Her novels generally focus the suppression of women characters in the hands of patriarchal society. I have studied this novel from the psychological perspective. I have explained that how the original self of the protagonist named Akhila buried deep in terms of societal norms and framed rules and how she revives herself back through her own effort. From the beginning of the novel she is portrayed as a martyr who sacrifices everything for the lives of others. After the death of her father she becomes the bread winner of the family. She never considers her wishes and dreams. While they talk about the marriage of her younger brother and sister she remains numb to voice out for her life. Her life remains incomplete without a husband and children of her own. She is unable to follow what her mind and heart says and seems a fragile woman. After some course of time she begins to resolve her inner struggle. After goes through self-analysis she called her lover Hari and begins her new life with him. She prefers to live for own self after considering the advices from her well-wishers. Thus her psyche gets its completeness after her long time inner struggle.

 Abstract

Water is one of the most important natural resources on the earth. Clean potable water is the right of each human being. As contaminated water can cause many diseases, it is necessary to monitor the quality of the drinking water on the regular basis. Therefore, this paper suggests the measurement of important water quality parameters like turbidity, pH and water color using multi-sensor technique. These measured quality parameters are analyzed and compared with the standard values provided by Bureau of Indian Standards(BIS) using MATLAB, to display the water quality results. As water quality is subjective by nature, proposed technique makes use of fuzzy logic model to overcome any data uncertainties and hence to obtain the more reliable and accurate water quality results. Proposed technique is intended to provide the accurate water quality results in very less amount of time compared to the conventional complexometric and colorimetric titration methods.

 Abstract

Using particle swarms to track and optimize dynamic systems is described. Issues related to tracking and optimizing dynamic systems are briefly reviewed. Three kinds of dynamic systems are defined for the purposes of this paper. One of them is chosen for preliminary analysis using the particle swarm on the parabolic benchmark function. Successful tracking of a IO-dimensional parabolic function with a severity of up to 1.0 is demonstrated. A number of issues related to tracking and optimizing dynamic systems with particle swarms are identified. Directions for future research and applications are suggested.

 Abstract

The body is believed to be composed of seven types of tissues called as Sapta Dhatu. These seven tissues work in coordination with each for proper physiological functioning of human body. Asthi is one among the seven Dhatu which are described in Ayurveda. In this article we are trying to collect the all general information of Asthi Dhatu defined in different texts from its formation to nutrition, number, nature, distribution, character, its importance in the journey of life and effects on body when it deviates from its normal character or number like Asthi Kshaya and Asthi Vriddhi. Some other factors which are related to Asthi Dhatu are also included like Asthidhara Kala and Asthivaha Srotas.

 Abstract

HOMA Therapy is the methodical expression since the Vedic discipline of bio energy denotes the method of eradicating harmful situation of the surroundings and refines the ambiance by action of flames/fire, equipped in copper pyramid tune to the biorhythm of morning (early bright)/evening (sundown). This means curing and purifies the ambiance through flames as a medium. Agnihotra is the essential flame in HOMA Therapy. Agnihotra religiously connect living being on this earth to restrain the energy from space & HOMA Therapy translates the same into significance materialistic performance of living organisms. With time this information was vanished but it is now has to be rejuvenated to make available people way in the direction of how to correct contaminated condition of the planet we find ourselves within nowadays. HOMA Therapy originates from Vedas, the most prehistoric body of information well-known to man. HOMA Therapy is given at a time when all hope is gone. It is given for all people. Anyone can do it, incorporate it into his or her daily life. HOMA has such a profound effect on plant life. It has a beneficial effect on animals including humankind but would be more easily detected in plants as they are simpler organisms.
