—This paper features the kinematic modelling of a 5-axis stationary articulated robot arm which is used for doing successful robotic manipulation task in its workspace. To start with, a 5-axes articulated robot was designed entirely from scratch and from indigenous components and a brief kinematic modelling was performed and using this kinematic model, the… (More)
—This paper deals with the design of a moving sliding surface in a variable structure plant for a second order system. The chattering phenomena is also dealt with during the switching process for an unstable sliding surface condition. The simulation examples considered in this paper shows the effectiveness of the sliding mode control method used for the… (More)
Active vibration control is an important problem in structures. One of the ways to tackle this problem is to make the structure smart, adaptive and self-controlling. The main objective of active vibration control is to reduce the vibration of a system by automatic modification of the system's structural response. This work features the modeling and design… (More)
The retinal nerve fiber layer (RNFL) is a vital part of human visual system, which can be directly observed by the fundus camera. This paper describes a method for glaucomatous retina detection based on Texture and Fractal description, followed by classification using support vector machine classifier. The color fundus images are used, in which the region… (More)
This paper deals a review of the uncertainty modeling in the placement of work space fixtures, say a container in the work space environment of the robot to do a particular task, i.e., to insert or remove some of the manufactured components from the bin or the container. The uncertainty model shown in this paper makes a compromise between the optical… (More)
This paper features the development of a kinematic model for a 5-axis stationary articulated robot arm and this model is used to do a pick and place task using a graphical user interface developed in C++ language.
This paper presents a conceptual view of the digital steganography & exploits the use of a host data to hide a piece of information that is hidden directly in media content, in such a way that it is imperceptible to a human observer, but easily detected by a computer. The principal advantage of this is that the content is inseparable from the hidden image.… (More)
This paper features the modelling and design of a type of multirate output feedback based controller (Fast Output Sampling Feedback-FOS) to control the flexural vibrations of a smart flexible Timoshenko cantilever beam for a Single Input Single Output (SISO) case by retaining the first 2 dominant vibratory modes. Piezoelectric patches are bonded as sensor /… (More)
