Static context model for context aware E-Learning
Minu. M. Das,Dr. T. Chithralekha,Dr. S. SivaSathya
International Journal of Engineering Science and Technology , 2010,
Abstract: Context aware E-Learning systems provide learning content according to a learner’s context. In order to determine a learner’s context, the parameters that constitute the context and the values of these parameters in the current learner’s situation have to be found. There are several existing context aware E-Learning systems and each of these are taking care of some of the context parameters - like learning styles, learner preferences etc. But, a standardized static context model that helps to capture a learner’s context in its ntirety is not available. This paper proposes a static context model that helps to capture a learner’s context. The static context model is developed by consolidating the various context parameters used in the existing context aware E-Learning systems and organizing them into an appropriate structure. The structure of the static context model along with the parameters that constitute the context is explained in the paper
Context Aware E-Learning System with Dynamically Composable Learning Objects
Minu. M. Das,,Manju Bhaskar,Dr. T. Chithralekha,Dr. S. Sivasathya
International Journal on Computer Science and Engineering , 2010,
Abstract: Context aware E-Learning systems provide learning content according to a learner’s context. In the existing context aware E-Learning systems there is no standardized set of context parameters considered and content is adapted based on a randomly considered set of parameters. In this work, a standardization of context model for context aware E-learning has been proposed. The design of the standardized context model requires that a learning object should not have a static monolithic structure but be flexible enough to be dynamically composed based on a learner’s context. Hence, a flexible learning object model and its representation are defined in this paper. A content management system which stores these flexible learning object constituents and assembles them dynamically based on a learner’s context is also described.
Genetic Algorithm Based Adaptive Learning Scheme Generation For Context Aware E-Learning

International Journal on Computer Science and Engineering , 2010,
Abstract: Context aware e-learning system helps to provide elearning contents which are customized according to the learner’s context. For generating context aware contents many adaptation parameters have to be considered. Customized learning path is one such adaptation parameter. In the existing elearning systems, learning paths is generated using several approaches. But in order to generate context aware contents, the profile context, infrastructure context, preference and learning context of learner have to be considered in addition the learning path. These context parameter values together constitute for the learning scheme of a learner. Hence learning path generation has to evolve into a learning scheme generation which accommodates the entire learner’s context. There are no learning scheme generation algorithms reported in the literature. In this paper a genetic algorithm based adaptive learning scheme for contextaware e-learning has been described.
A Control System Retrofit for a Plastic Bag Making Machine
International Journal of Engineering Science and Technology , 2011,
Abstract: This work presents the development of a microcontroller system to replace a problematic mechanical system of a plastic bag making machine. After detailed study of the existing system the theory of finite state machines is used to model the proposed retrofit, using simulink and stateflow toolboxes of MATLAB. Using the model, theretrofit system is partitioned into hardware and software components. The retrofit is implemented using Microchip’s PIC16F84A 8-bit microcontroller. The developed retrofit performance is the same as the original machine. Due to the flexibility of microcontrollers, other operation and diagnostic features can easily be added.

Turkish Studies , 2007,
Abstract: Teaching languages to non-native speakers is very sophisticated and time-consuming work. As well as other languages, Turkish must be taught both theoretically and practically. It is well known that developing a curriculum and planning of the course are two basic factors in teaching foreign languages successfully. At this point, preparation of a well designed and an applicable syllabus can be a good start for an effective teaching. In this proposal, the importance of preparation of a syllabus was evaluated and some suggestion on its preparation for non-native Turkish language speakers were offered. The syllabus mainly contains course/instructor information and a course schedule. Basically, it was expected that a syllabus could inform students in advance about the course and topics and make them to be prepared accordingly.

Abstract: : Image Fusion is one of the major research fields in image processing. Image fusion process can be defined as the integration of information from a number of registered images without the introduction of distortion. It is often not possible to get an image that contains all relevant objects in focus. One way to overcome this problem is image fusion, in which one can acquire a series of pictures with different focus settings and fuse them to produce an image with extended depth of field which helps in clinical diagnosis. Image fusion techniques can improve the quality and increase the application of these data. The proposed paper uses multi-image Contrast enhancement for PCA fusion of medical images. The objective of this paper is to propose a technique for fusion of human brain MRI images based on Principal Component Analysis and to improve the visibility of medical images by applying contrast enhancement existing techniques. The PCA fusion technique adopted here improve resolution of the images. The PCA algorithm builds a fused image of several input images as a weighted superposition of all input images. The resulting images contains enhanced information as compared to individual images and also apply Contrast Enhancement technique to improve visibility of medical image details without introducing unrealistic visual appearances and/or unwanted artefacts. It also gives the quality comparison study of original medical images before fusion, after applying PCA and various existing techniques for contrast enhancement for those medical images.

Abstract: Though the existence of Aluminium was first established in the year 1808, it took almost 46 years to make its production commercially viable. The research work of several years resulted in extracting the aluminium from the ore. Aluminium is third most available element in the earth constituting almost 7.3% by mass. Currently it is also the second most used metal in the world after steel. Due to the consistent growth of Indian economy at a rate of 8%, the demand for metals, used for various sectors, is also on the higher side. As a result, the Indian aluminium industry is also growing consistently. The production of aluminium started in India in 1938 when the Aluminum Corporation of India's plant was commissioned. The plant which was set up with a financial and technical collaboration with Alcan, Canada had a capacity of producing 2,500 ton per annum. Hindustan Aluminum Corporation (Hindalco) was set up in UP in the year 1959; it had a capacity of producing 20,000 ton per annum. In 1965, a public sector enterprise Malco which had a capacity of 10,000 ton per annum was commissioned; by 1987, National Aluminium Company (NALCO) was commissioned to produce aluminium. It had a capacity of producing 0.218 million ton. India is world's fifth largest aluminium producer with an aluminium production competence of around 2.7 million tones, accounting almost 5% of the total aluminium production in the world. India is also a huge reservoir of Bauxite with a Bauxite reserve of 3 billion tones.
An Understanding of Rasa Dhatu as Described in Ayurveda in the Light of Modern Science
Dr. Archana Gupta,Dr. P. S. Byadgi
International Journal of Pharmaceutical and Phytopharmacological Research , 2012,
Abstract: Ayurveda says that the origin of body is from anna. After proper metabolic process the food materials changes into anna-rasa or adhyarasa dhatu, which helps in the formation and nutrition of the other dhatus of the body. The main role for the formation of rasa and mala is agni, which resides in the stomach. Two types of rasa dhatu present in the body, one is sthayi dhatu and another is poshaka dhatu. Heart has been the main place of rasa dhatu. When rasa dhatu is functioning properly helps in the formation of other dhatus, nourishes the body and also improves skin texture. If rasa-dusti present either due to vriddhi (increase in quantity) or due to kshaya (decrease in quantity) of rasa dhatu then various diseases has been occurred.
Darwin on the Treatment of Animals: His Thoughts Then and His Influence Now
Dr. Donna Yarri,Dr. Spencer S. Stober
Journal of Arts and Humanities , 2013,
Abstract: Charles Darwin’s theory of evolution has seriously challenged traditional religious views on the origins of life, as well as on our human-animal similarities. Darwin is often referenced in literature on animal ethics with regard to his contention that the difference between humans and other animals is one of degree rather than of kind. This paper posits that Darwin’s writings and theory make more positive contributions to the contemporary debate on animal ethics than for which he has previously been given credit. This paper addresses important aspects of Darwin’s theory for understanding our relationship with other animals and the implications for their subsequent treatment. First, this paper considers themes in Darwin’s original writings regarding relationships among different species; second, enhancements to his theory in support of these themes; and third, recommendations for how these themes can and should inform our moral reasoning and successive treatment of other animals.
