Integrated circuits used in critical and high reliability applications have often strict test requirements including high test coverage and limited test time. Achieving a high test coverage using built-in self-test (BIST) has proven difficult. Methods such as test point insertion or deterministic BIST can provide high test coverage but introduce significant area overhead and design effort. In this...
Early warning and intelligent decisions have proved to be important tools to handle the unprecedented events (wildcards) that might emerge in the future. Relying on forecasting techniques only are not enough to shape the future, since they depend only on the historical shape and they generate one image of the future. The Futures Methodologies are capable of overcoming the constraints imposed on the...
A goal in soft real-time systems is to maintain quality of service in the presence of variations in computation times while efficiently utilizing the system. Several feedback-based scheduling algorithms have been proposed for this application. This paper presents a prediction-based bandwidth reservation policy with the same goal. A proof is presented to show stability, of the job queue. Simulation...
The problem of a three dimensional free convection flow with mass transfer of an incompressible viscous electrically conducting fluid past a uniformly moving porous vertical plate with transverse sinusoidal suction velocity is considered. A magnetic field of uniform strength is assumed to be applied normal to the plate. The expressions for skin-friction at the plate in the direction of flow, rate...
The paper presents an investigation into methods for maximizing the spectral Efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. As part of this, an investigation of detrimental effects on OFDM is presented, the use of pilots between carriers, Clipping Distortion, Additive Complex Noise (ACN) on modulation QPSK rate, on multi path Synchronization error, using estimation results...
In this paper, a method for adapting conventional controller are used to adapt an adaptive parametric black box controller (APBB). The APBB controller will be adapted such that the plant should follow a desired trajectory which is given by a reference model. The parameters of APBB controller are estimated by using recursive least square method. The estimation goal is for the parameters to converge...
There has been a recent proliferation in wireless infrastructure network deployments. In a typical deployment, an installer uses either a one-time site survey or rules of thumb to place wireless access points and allocate them with channels and power levels. Because the access point location problem is inherently complex and one that requires tradeoffs among competing requirements, these approaches...
