Data sciences have been commercially adopted by various industries as a new arising era of technology but in the field of research still a lot more can be achieved. Data in data warehouse generally reflects the historical data that is separated from the operational data of the industry. The exploration of data is done by the online analytical processing (OLAP). OLAP from its initialization has been a subject of various modifications. It has been reviewed and imposed under various conditions to test its working. Majorly it has been used with various kinds of datasets such, spatial, traditional, sequential, high-dimensional etc. Research now is not only confined to any particular data source in fact a wide spectrum of data sources are to be considered. Apart from analysing the data, visualizing also is an important aspect to be considered, as perception creates a more plausible impression. This paper discusses various existing methodologies of data analysis. It also refers to the frequently used visualization techniques and the various commercial BI tools that are successful and the methods that these tools work on. It also aims towards providing an interface that would analyse, link and visualize the data in the same frame.

Wireless sensor network is a collection of large number of sensor nodes that are deployed in large number to monitor the environment. There is a great technological advancement in wireless sensor network during last few years. Due to low-cost, small-size, nature of Wireless Sensor Networks (WSNs), it allows them to sense the information in various hostile environments (e.g. Military surveillance, battlefield). So, to fully achieve the capacity of WSNs, sensor nodes need to cooperate in the collection and must disseminate topology information. These sensor nodes specifically operate in a multihop routing. Sensor network in muiltihop routing faces a variety of risks which is also due to the harsh operating environments. In this paper a fuzzy based approach is introduced which will enhance the routing security and reliability in WSNs.

The total number of vehicles in the world has experienced a remarkable growth, increasing traffic density which results in more and more accidents. Therefore the manufactures, researchers and government is shifting focus towards improving the on road safety rather than improving the quality of the roads. The good development in the wireless technologies emerged various new type of networks, such as Vehicular Ad Hoc Network (VANET), which provides communication between vehicles themselves and between vehicles and road side units. Various new concepts such as smart cities and living labs [1] are introduced in the recent years where VANETs plays an important role. A survey of various Intelligent Traffic Systems (ITS) and various routing protocols with respect to our proposed scheme is described in this paper. It also introduces a new scheme consist of a smart city framework that transmit information about traffic conditions that will help the driver to take appropriate decisions. It consists of a warning message module composed of Intelligent Traffic Lights (ITLs) which provides information to the driver about current traffic conditions.

A novel approach to develop a Fast Fourier Transform (FFT) for real valued signal using Radix 2 algorithm is proposed in this paper. Methodology is to modify the flow graph of the FFT architecture. Redundant components are replaced by the imaginary computations. Hardware complexity of this RFFT architecture will be low compared to Radix 2 and Radix 2 algorithms in terms of adder, multiplier and delay. This proposed architecture maximizes utilization of hardware with no redundant computation. RFFT is used for real time applications and also in portable devices where low power consumption is the main requirement. So accordingly vedic multiplier and carry save adder has been used in the proposed work.
