Pages: 83 - 89
Nanotechnology has led to the evolution of nano-machines which are tiny components comprising of arranged set of molecules performing pre-determined tasks. The interconnection of nanosensors and nanodevices with Internet has led to development of next evolutionary step towards IoT called “Internet of Nano Things†(IoNT). WNSN for intrabody application consist of integrated nano-machines, diffused in the human body for collecting diagnostic and prognostic processes and aid in the treatment of patients through accurate tumor and disease detection. Medium Access Control (MAC) protocols are needed for the communication between nano-devices and for the access coordination to the wireless channel. Since classical MAC protocols cannot be used due to the peculiarities of nano-devices and the Terahertz band, they are not suitable for WNSN. The main objective behind this paper is to provide review on so far developed MAC protocols in novel nano-scale communication approaches along with architectural requirements for implementation, communication and networking aspects, significant challenges and security issues.

Pages: 97 - 103
Casting is one of the oldest and mostly used production methods in industry. The traditional casting has certain disadvantages like poor strength due to hot tears, shrinkage and poor surface finish. The properties of casted product mostly depend on the microstructure after solidification. Providing Mould vibration during casting is one of the latest techniques employed in order to get better structure in the solidified casting. Mould vibration during casting gives reduced amount of shrinkage, better morphology, surface finish, and less chances of hot tear. In this research work the effect of mould vibration on casting during solidification of Al-6063 alloys for different values of wave lengths at fixed pouring temperatures is investigated to understand the changes in microstructure and mechanical properties of casting .The casting has been prepared in iron EN8 mould with and without vibrations. The frequencies varied from 0Hz to 40 Hz. A casting has been made without vibration as well to compare the results of castings with vibration. The experimental results showed significant grain refinement and remarkably improvement in mechanical properties of casting with mechanical mould vibration during solidification.

This paper is about Rurbanisation of the Pratappura (Balva) village, Gandhinagar District, Gujarat, India. Today world is growing fast so due to migration of people from rural area to urban area is increase daily thus rural area are not develop well compare to urban area. So today’s biggest, issue is migration of people from rural area to urban area. Therefore, in Vishwakarma Yojana Phase IV we will work on rural issues and problems, listing out existing amenities and give best economical solution. It is the project towards making Rurbanisation by providing the social infrastructure, physical infrastructure, socio-cultural infrastructure facilities with method of giving Redesigning, Reimaging, Repair & maintenance, and Sustainable planning for basic need of village. It is about providing urban level facility in rural area. So migration of people urban to rural area decrease and remigration of people are possible. In village there are some infrastructure facility is not available like primary health center, solid waste management, public library, pond and public toilet. So we gives the solutions, design, sustainable planning and cost estimation for infrastructure facilities for Pratappura village.

Year: 2017, Volume:4, Issue : 2
Pages: 123 - 126
Most of the Indian religious philosophies and rituals believe in idol worshiping and from the ancient time, temple has been playing an important role in the society. It may be religious or socio-cultural point of view, construction of temples has been patronized from 3rd century BC. Illustrated by the Indian Silpa-sastras, Indian temples can be categorized in three main types, i.e. Nagara, Dravida and Vesara styles. As the non-hindus invaded India in 11th century, many Nagara style temples were looted and destroyed and today a very few specimen exists to study the styles and forms, and most of them are found prominently in the state of Odisha. Apart from the Nagara style of temples, Odishan archaeology also preserves few examples Vesara style temples. But the question arises that from where the shape of Odishan temples evolved? It has been described and illustrated that temple architecture came to Kalinga after the Mouryas and many temple styles were influenced from temples of North and Central India. But a thorough study of Odishan vernacular architecture answers it with a different notion. The styles and shapes used in construction practices of rural areas in Odisha are reflected in the temple styles. This paper focuses on the significant elements and characters; those have influenced the evolution of shapes of different temple forms in the milieu of Odishan Temple Architecture.
