Electronic fare management is a subject currently intensively discussed all over. A lot of different solutions have been implemented in the past. But a new kind of solution was coming up in the last few years: mobile ticketing. This ticketing concept uses customer's mobile devices to buy public transport tickets, instead of special devices owned by the transport operators.Another topic of discussion...
Computer applications require interaction between humans and computers. This interaction has to be lucid and is a challenging task for the traditional devices such as keyboard, optical pen, mouse etc. Hand gestures are more natural, compared with actions associated with the traditional devices. Use of hand gestures to operate machine would make interaction very interesting and easy. Gesture recognition...
Digital images can be secured by using methods of scrambling/encryption. A number of techniques have been proposed to encrypt the digital images. One such technique, which secures the content of the digital image by making it unreadable to the spying eyes, has been proposed in this paper. This paper proposes an image scrambling technique, using transforms for assorted color spaces. A comparison of...
Cancer has grown universally as a disease in recent years and it has proven to be the major cause of fatality in humans. The main focal point in this paper is on leukemia - a specific type of blood cancer. The disclosure of leukemia is done with the help of examination of the physical properties of the cells present in the bone marrow smear. This paper introduces peculiar detection of leukemia using...
An efficient three phase interleaved DC-DC converter is proposed with inductor current and voltage control. The use of multiple sensors for each phase current is eliminated using current reconstruction. This reduces the number of current sensors and improves the reliability. The inductor current control is achieved using single current sensor which measures DC-link current. The proposed converter...
Face recognition is a field which has risen to prominence because of its tremendous range of applications. Traditional biometric systems relied heavily on user interaction. Face recognition addresses this issue. It involves no user interaction. Modern security systems have seen an uncharacteristically rapid growth in the use of face recognition based systems seldom seen hitherto. Face recognition...
A weigh feeder system is a small conveyor integrated with a belt weigh bridge and speed sensor and driven by a variable speed Motor. These are widely used in Mineral/Ore and chemical industry where a measured rate of solid raw material is fed to Reactors and furnaces. In order to accurately control solid flow rate, the speed of motor/ belt is varied to compensate for the variation of quantity of solid...
Distributed generation (DG) devices can be strategically placed in power systems for grid reinforcement, minimizing real power losses, improving bus voltages and efficiency of distribution system. The optimal DG placement (OPDG) method is used to provide the best locations and sizes of DGs to optimize electrical distribution network operation taking into account DG capacity and voltage constraints...
The project aims to provide communication anywhere anytime when the telecommunication network is not available for example after a disaster, or in sparsely populated areas. Mobile phones normally can't be used when cellular networks fail as in case of disaster. This means that millions of people around the world are not able to communicate, when they need it most as most of its functionality are supported...
The Wireless Sensor networks (WSNs) consist of sensor nodes which are deployed in environment where the exhausted batteries of nodes are difficult to charge or replace. Main problem in WSNs is Energy consumption which is caused due to overhearing, idle listening, redundant transmission and collisions. To improve the energy efficiency of WSNs different protocols are designed. Efficient Multi-hop Broadcast...
This paper exhibits an evaluation between three textile antennas at 2.45 GHz such as linearly polarized rectangular patch antenna (LPRMSA), circularly polarized corner cut square antenna (CPCCSMSA) with coaxial feed and rectangular slot antenna (CPRSA) with coplanar waveguide feed. Need of compact size antennas due to handy wireless communication devices. The most appropriate antenna for wireless...
This paper is based on the designing of microstrip patch antenna for wireless communication. The antenna array is designed to transmit at 2.4 GHz and 3.7 GHz. The main contribution of the paper is the integration of metamaterials with a `E-shape' slotted microstrip patch antenna, in order to achieve high gain and enhance the beam directivity. Implementation of metamaterial in this application enhances...

Numerous control strategies are introduced in both Gate and CMOS level, Multipliers are the basic design unit of a reconfigurable cryptographic processor...
The power amplifier's performance in a selective level mapping (SLM) STBC-OFDM is drastically degraded due to the presence of nonlinearities. Further the back off to be applied to the system is a function of the peak to average power of the system.A high merit factor phase sequence set achieves improved PAPR reduction compared to conventional Hadamard sequence set. In this paper, we determine the...

For practical CR systems have limited a priori knowledge of the primary users signal characteristics , spectrum sensing have three type energy detection, match filter and cyclostationary feature base detection. One of the main benefits of the cyclostationary beam forming algorithms is their...
WSN-Wireless sensor networks are greatly in focus for the researchers. The use of WSN is foreseen for bringing massive changes in data gathering, processing and broadcasting. One of the most central design concerns in WSN is energy consumption. Hierarchical routing protocols are best acknowledged in respect to energy efficiency. Mobility based clustering (MBC) provides fruitful packet delivery rate,...
Wireless Sensor Network is a rising technology that guarantees ample amount of applications in various domains. The creations of WSNs completely rely on existence of various hardware and software and WSN developed with limited battery life. Many WSN routing protocols are designed so that it makes use of fewer resources and improve the performance and lifetime of network. Energy consumption is one...
This paper proposes an innovative approach to traffic density estimation. It defines a method that focuses on reducing computational time and complexity by extracting row, column and diagonal mean feature vectors from the image. Then these feature vectors are used to train classifiers and the images are classified as low, moderate or high traffic situations. The system works in 2 phases: Training...
This Paper presents a brief overview of a generalized automation interface that will act as an additional module to the existing electrical or electro-mechanical system. This will help the user (at home) or a supervisor (at a factory) to control and monitor the appliances or various machinery, in a convenient manner. The focus is on designing and development of a system which is user friendly and...
With the increasing share of wind in power generation, the dynamic behavior of the power system will change considerably due to different technologies used for wind and conventional generators.
