Usage of social network for topic identification has become essential when dealing with event detection, especially when the events impact the society. In order to address this task, machine learning algorithms and natural language processing techniques have been extensively used. In this paper, an approach to obtain meaningful data from Twitter has been discussed. Further, Latent Dirichlet Allocation...
Wireless Sensor Network is a technologically high in demand field which is used in plenitude of areas like military surveillance, environmental control, automatic manufacturing environments, smart homes etc. WSN is an affiliation of relatively large number of nodes that are spread across a large geographical area. The components include the features of sensing, data processing and communicating. For...
Today when there are more than 1 billion Android users all over the world, it shows that its popularity has no equal. These days mobile phones have become so intrusive in our daily lives that when they needed can give huge amount of information to forensic examiners. Till the date of writing this paper there are many papers citing the need of mobile device forensic and ways of getting the vital artifacts...
The use of digital watermarking technique in multimedia applications is evolving day by day. In this digital world copyright protection and claiming ownership on digital data is a big challenge. Watermarking multimedia objects/files is one of the solutions to this problem. Digital watermarking has been fascinating many researchers since last few decades. There is no algorithm that has been accepted...
Wireless Sensor Network is a network of small battery powered sensing devices (known as sensing nodes), capable of sensing the physical parameters like temperature, humidity, pressure, motion, etc. from its environment of deployment and report it to a central node called base station. These nodes collaborate with each other to fulfill their task. As the energy source is constrained in WSNs, it should...
Wireless sensor network (WSN) consists of large numbers of small battery powered sensing device called sensor node, having the ability to sense the data from environment of deployment. Limited energy is of prime concern for the WSNs, as source of energy is finite. Sensor nodes are used to periodically sense the environment, do limited processing before transmitting the sensed data to their cluster...
The D-Qaxis modelling of the shaded-pole induction motor employing the state vector analysis is approached to determinethe periodicity and chaotic phenomenon under different system parameters are observed. Accordingly, a chaotic-speed control of a fan can be achieved by appropriately varying the motors' internal parameters or the operation condition. Computer simulations have been developed to confirm...
