The present research work explores application of perimeter method to determine fractal dimension for both glaucoma and non glaucoma eye. Fractal dimension is a real value treated as over simplified diagnostics parameter to determine earlier detection of glaucoma. A perimeter method is a well known method adopted to determine the fractal dimension of natural objects such as leaves and some biological...
The paper presents the design, implementation of the a unique type of computer controlled wireless mobile surveillance robot equipped with intelligence. Building an experimental autonomous mobile wireless vehicle, which has the ability to perform in real time environments is both a technical and scientific challenge and demands the development of systems for perception, modeling, planning and navigation...
In this paper, a novel hardware design along with software design for developing an efficient radio communication system w.r.t. a mobile robotic system is presented. The developed hardware & software to control the mobile robotic system using an efficient communication link shows the effectiveness of the developed method.
In this paper, the modeling and design of a multirate output feedback based discrete sliding mode control scheme application for the vibration control of a smart flexible Timoshenko cantilever beam for a single input single output (SISO) case by retaining the first two dominant vibratory modes is presented. In our work, the effect of shear and axial displacement has been considered. The algorithm...
This paper deals with the design & development of a theft control system for an automobile, which is being used to prevent/control the theft of a vehicle. The developed system makes use of an embedded system based on GSM technology. The designed & developed system is installed in the vehicle. An interfacing mobile is also connected to the microcontroller, which is in turn, connected to the...
A simulation & implementation of a shortest path from the source to the destination in the amidst of obstacles using configuration space approach both with translations & rotations is presented in this paper. One of the most important problems in robotics is the task-planning problem. A task is a job or an application or an operation that has to be done by the robot, whether it is a stationary...
This paper presents a novel design and implementation of a 3-Phase, 400 Hz, 1 KVA sinusoidal PWM inverter. The input voltage (45-48 V DC) obtained from photovoltaic cell, is stepped up into 200 V DC with fly-back converter and regulated with current mode control method, applied to a 3-phi bridge system. A sinusoidal PWM generator is used as firing circuit for turn-on and turn-off of the MOSFETpsilas...
Optical transmission techniques have been researched for a couple of decades over the past dozen of years or so. A number of algorithms have been proposed, developed and implemented in optical networks. Existing research has proved that effective routing wave-length assignment schemes has improved the efficiency of the networks by reducing the blocking performance of optical networks. This paper proposes...
This paper is intended for on how mobile technologies can play an important role in the evolution of M-learning. In Second Generation, GSM can be introduced in three ways such as general packet radio services, continuous connection to the internet not requiring dial-up connection reaching up to 171.2 Kbits /s. Secondly, Blue tooth is a chip technology, that allows short range data and voice transfer...
This paper presents the modeling and design of a periodic output feedback (POF) controller to suppress the vibrations of a smart thin walled composite box beam. Collocated piezoelectric patches are bonded as sensor / actuator to the master structure at a certain finite element location on the beam, i.e., nearby the fixed end of the composite box beam. The beam structure is modelled in state space...
