PIM-SM is the only deployed intra-domain multicast routing protocol that builds both shared and source-based trees. However, it does not provide an efficient mechanism to switch between the two modes. The PIM-SM switching mechanism proposed in this paper aims to improve both network and receivers requirements. It is a coordination-based mechanism in the sense that all concerned receivers contri...

We propose a novel classifier technique, named short-time burst degradation classifier (SBDC), with the ultimate goal of improving the short-term delay and the packet jitter for real-time traffic. The main idea of the proposed classifier is to provide the ability to manage the queuing delay in order to decrease the impact of short-time scale burstiness of the traffic in a flexible manner, since...

This paper presents a novel RF MEMS (Micro Electromechanical System) fixed-fixed switch for very fast switching. Using the obtained equations, the switching time depends on the stiffness and effective mass of the switch beam so that the switching time will be decreased by higher stiffness (spring constant) and lower effective mass. In new design, the suspension bridge is a three-layer beam so t...

In this study Hinted Cell Switching is introduced as a new alternative to the Mobile IP advertisement based movement detection methods. It is a method that relies on “hints” generated during subnetwork layer hand-offs for reacting faster to Mobile IP hand-offs. In this study the performance of Hinted Cell Switching is compared through the use of simulations against those of advertisement based ...

In this paper, non-carrier based digital switching functions and patterns are developed using VHDL language (DSFPV).Non-Carrier based switching angle method is selected for the reduced distortion characteristics. Different methods of switching angle methods like equal phase method, half equal phase method, half height method and feed forward method are designed and developed using VHDL coding. ...

This paper presents a new supervisory control scheme, which is based on a control-relevant switching logic. Unlike most of the existing switching methods considering only estimator performance, the proposed scheme takes both estimator and controller performance into account. As an index to the controller performance, an iISS (integral-Input-to-State Stability) Lyapunov function is employed; it ...

A Lyapunov based switching control design method for non linear systems using fuzzy models is proposed. The switching controller consists of several linear state feedback controllers; only one of the linear controllers is employed at each moment according to a switching scheme. The gains of the linear state feedback controllers are derived based on Lyapunov stability theory. The fuzzy design mo...

the purpose of this study was to determine the influence of platform switching on stress distribution of two different implant systems using three-dimensional (3d) finite element models.six 3d finite element models were created to replicate two different implant systems with peri-implant bone tissue, in which six different implant-abutment configurations were represented: model xive-a: 3.8-mm-d...
