Design and implementation of active headrest are having challenges as the performance of noise reduction at the ear reduces due to head movement. In this paper, an active headrest is implemented using two secondary loudspeakers and two error microphones using a multi-channel active noise control (ANC) algorithm running on a dSpace dS1104 platform. The performance of an active headrest was studied...
Cluster analysis is a principal method in analytics domain of data mining. The algorithm used for clustering directly influences the results obtained from applying the clustering algorithm (clusters). Data clustering is done in order to identify the patterns and trends not identifiable from just looking at the data. Clustering may be supervised (if the machine training data set is available) or unsupervised...
OCR is the most active, interesting evaluation invention of text cum character processing recognition and pattern based image recognition. In present life OCR has been successfully using in finance, legal, banking, health care and home need appliances. The OCR consists the different levels of processing methods like as Image Pre Acquisition, Classification, Post-Acquisition, Pre-Level processing,...
In this paper the PID controller is designed to control the liquid level in the Spherical tank system (STS). The STS is modeled in fractional order and is approximated to an integer order by using oustaloup's approximation algorithm. The higher order integer system is reduced to a 2nd order by using Balanced Truncation (BT) method. The PID controller is designed for this reduced order model and the...
This letter introduces a novel, fast, efficient, and global optimization algorithm called hybrid invasive weed optimization and wind-driven optimization (IWO/WDO). The proposed algorithm is implemented to synthesize the uniformly excited (, ) linear sparse array pattern having a minimum sidelobe level (SLL), and null control with constraint on beamwidth to minimize the...
In recent days it becomes very difficult task to manage security on large network and practically not possible to keep security scanner on every networks for protecting the system from illegal users. This problem can be solved with prevention systems which come in strategic role of Intrusion Prevention Systems that is taken as extended and enhanced version of IDS. By using this system we can upgrade...
This paper presents synthesis of unequally spaced linear array antenna with minimum sidelobe suppression, desired beamwidth and null control using wind driven optimization (WDO) algorithm. The WDO technique is nature-inspired, population based iterative heuristic global optimization algorithm for multidimensional and multimodal problems. The array synthesis objective function is formulated and then...
Internet routers play an important role during congestion. Most of the Internet routers have buffers at input and output ports, which hold the packets in the time of congestion. An active and efficient management of buffers is critical to minimize the congestion. However, queue management becomes very complex because of dynamics of input packets. We direct out attention to the variable length virtual...
