Assorted analytical methods have been proposed for evaluating the performance of a slotted ring network. This paper proposes MGM (Matrix Geometric Method) to analyze the station buffer of a slotted ring for DT (Discrete-Time) queueing. The slotted ring is analyzed for infinite station buffer as a late arrival DT system. Utilizing the characteristics of 2-D Markov chain, various performance meas...

Due to developments in additive manufacturing, the production of piezoelectric materials with complex geometries is becoming viable and enabling the manufacturing of thicker harvesters. Therefore, in this study a piezoelectric harvesting device is modelled as a bimorph cantilever beam with a series connection and an intermediate metallic substrate using the plain strain hypothesis. On the other...

* This work is supported by DOE SBIR No. DE-FG03-96ER82213. Abstract We consider novel designs that provide field flatness of fundamental mode in transverse dimensions of planar rf structures. These designs include waveguides with slotted irises and/or dielectric loaded side openings. The specially modified, advanced planar structures can be produced with available technology for a number of pu...

This paper presents research on a new type of fabricated steel–wood composite floor material in the style slab-embedded beam flange, using test methods and finite element numerical analysis to study flexural load-bearing performance slabs. Through experimental phenomena, failure process mechanism are analyzed, deformation ultimate bearing capacity assessed. model, influence connection mode beam...

We consider the problem of stability of slotted ALOHA for a system consisting of N users communicating with a common receiver, which employs spatial diversity to receive multiple transmissions simultaneously. We introduce a general packet reception model to incorporate multiple packet receptions since the collision channel model is no longer valid in such a scenario. We characterize the stabili...

In this paper, the bandwidth of rectangular Microstrip antenna is enhanced by ‘I’ slotted rectangular microstrip patch antenna. In some applications which the increased bandwidth is needed, proposed antenna is one of the alternative solutions. The proposed antenna has been designed at the 2 GHz frequency. The frequency band of proposed antenna is in between (1.64-3.26 GHz) the fractional bandwi...
