Surface integrity is an important term that describes the surface behaviour of a ground component. Grinding defined as finishing operation has high specific energy consumption. High heat generation while grinding, adversely affects surfaces. With development advanced materials such superalloys, this process widely used in bulk machining for making critical components dynamic loading. Therefore, it becomes necessary to investigate components, their primarily determines performance and...

Pond ash (PA) and cement kiln dust (CKD) are major products from thermal power stations manufacturing industries pose disposal difficulties. This research work focuses on the geotechnical properties of pond mixed with polypropylene (PP) fiber. Various experimental tests, including standard Proctor test, California bearing ratio (CBR) direct shear triaxial were performed. was 10, 15, 20, 25, 30% CKD 0.5, 1, 1.5% Standard tests carried out various proposed proportions in order to obtain...

The study of multi-agent capture and manipulation an object has been area active interest for many researchers. This paper presents a novel approach using Genetic Algorithm to determine the optimal contact points total number agents (mobile robots) required stationary generic 2D polygonal object. After goal are determined then reach their respective goals decentralized projective path planning algorithm. Form closure is obtained concept accessibility angle. boundary first expanded robots...

SUMMARY Genetic algorithm is used to determine the optimal capture points for multi agents required grasp a moving generic prismatic object by arresting it in form closure. Thereafter, approach their respective goals using decentralized projective path planning algorithm. Post arrest, guided along desired linear goal point. Form closure of obtained concept accessibility angle. A convex envelop formed around object, and on boundary are mapped onto envelope. The robots first, then, converge...

The presented work examines the pullout response of open-ended pipe helical soil nails in cohesionless soil. Assessments are made on basis installation and displacement controlled test. were designed to isolate plug effect, inner skin friction, bearing resistance contribution nail capacity. findings suggest that as diameter number helices increases, torque stress also increases. length increases with increase penetration depth ratio up five thereby becomes constant. At qual five, is 10%...

This paper proposes a novel approach to determine the optimal contact points for constraining prismatic object by group of mobile robots. The are found such that twin objectives minimum number robots required form closure and least force grasping satisfied. assumed be able apply normal without friction, on objects. Genetic algorithms have been used solve problem. advantages proposed method as is in it can resist all external forces moments. A simulation has made Matlab shows algorithm works...

A GA based method is proposed to obtain the optimal capture points for constraining a moving prismatic 2D object using multi agents. Frictionless point contact at robot and interface assumed form closure obtained accessibility angle. An objective function optimized that minimizes forces number of robots required closure. The first avoid obstacles converge on C- space surrounding object. After captured mobile reorient themselves optimally push goal point. Simulation results prove method.

This paper outlines a multiband antenna design based on fractal concepts. Simulation studies to investigate the influence of fractals resonant frequencies are presented. The numbers varied and frequency bands is observed

A GA based method is proposed to obtain the optimal capture points for constraining a moving prismatic 2D object using multi agents and then transporting it desired goal point. Frictionless point contact at mobile robot interface assumed form closure obtained accessibility angle. An objective function optimized that minimizes forces number of robots required closure.
