There are numerous studies on the compound structures, made of two dissimilar materials, joined by using modern welding techniques, which find applications in many fields of engineering because of achieving a better response under various loading conditions. The mechanical and thermal buckling behavior of compound stepped structural members, like two stepped circular plates, consisting of two concentrically placed different materials, is of particular interest to engineers in design the modern structures. These have a wide range of applications owing to their higher values of strength to weight ratio, compared to isotropic plates.
In this paper, the influence of the thickness ratio and the radius ratio of the two concentric steps on the buckling of stepped compound circular plate with the material combinations of aluminum, titanium, steel and copper, for simply supported and clamped boundary conditions, are studied by using the Rayleigh - Ritz (RR) method. The results show the effect of the material combinations on the mechanical thermal buckling load parameters of the stepped compound circular plates with respect to the thickness and the radius ratios.

Now a day’s mobile technology plays key role, in various environments identification of objects can be done manually, to improve the efficiency of an identification of objects we are using RFID tags. RFID tags track objects in supply chains, and are working their way into the pockets, belongings and even the bodies of consumers. Tag collision occurs while two or more than two tags deliver their unique identification (UID) to the reader. Since collision, which would significantly affect the efficacy of RFID, has been one of the major study issues for RFID technology, we have developed a solution, bit competed algorithm (BCA), to solve the collision problem occurred in RFID system and consequently improve the efficacy of RFID. This paper briefly presents what are the components in RFID system, Architecture of a RFID system, what are the frequency ranges used in the RFID system and what are the problems occurred in the RFID system. Here we develop a system as a prototype for object identification. By using this technology objects can be tracks more efficiently, it provides more security, it save time and money.Keywords

The topology of Teaching is changing its wings from a vibrant classroom to an ingenious active-based classroom. In this context, up-gradation to build an adaptable Covid-19 system that revamps the traditional way of Teaching tautology to a generic active learning-based system has been essential aid in the topology of Teaching and Learning mechanisms. A conventional adaptive active learning system that justifies the topology needs and pedagogy builds a passionate Teaching and Learning environment. This paper illustrates a pedagogy selected to outline the OSI Model in the Computer Networks and vibrant the deliberate classroom environment to an active learning classroom environment that inspires the classroom teaching form to a compassionate Tautology of Active Learning environment. The literature suggests many ways to imbibe a concept, but literature misrecollects the pedagogy's selection according to the topology.Keywords
