Digital controllers sitting at the digital-analog boundary often react to specific analog events that can be modeled in terms of predicates over real variables. The specifications for such controllers are also naturally described in terms of similar events, and can be formally expressed with simple extensions of assertion languages. This paper studies the(More)
Automata-based scheduling is a recent technique for online scheduling of software control components in embedded systems. This letter studies one important aspect of automata-based scheduling that has not been studied in the past, namely resilience to faults. The goal of the proposed technique is to create an automaton that recommends the scheduling(More)
The mobile phones grow to be an essential part of our everyday life, with smart phone sales at present greater than before very much and also user demands to run lots of applications have enhanced. The victory of next invention mobile phone communication based on the capability of service suppliers to engineer innovative added worth to video services. The(More)
Silica and phosphate based bioactive glass nanoparticles (58SiO2-33CaO-9P2O5) with doping of neem (Azadirachta indica) leaf powder and silver nanoparticles were prepared and characterised. Bioactive glass nanoparticles were produced using sol-gel technique. In vitro bioactivity of the prepared samples was investigated using simulated body fluid. X-ray(More)
There has been recent interest in automata-based scheduling for dynamic adaptation of schedules for embedded control software. Recently we have shown how automata-based scheduling can be extended to account for the possibility of faults in application of control. In this paper, we address the problem of automata-based scheduling when latencies are(More)
Model based frameworks like Simulink/Stateflow for developing software control algorithms advocate the analysis of an abstract discrete state model of the controller before developing the actual code for the implementation. Though some of the existing tools support automatic code generation from the model, in actual practice the code is developed manually(More)
For several decades, computer's memory has been volatile. High speed memories such as DRAM and SRAM have been used as main memory and cache memory respectively. Magnetic disks are used as the persistent secondary storage devices. The present DRAM based main memory has reached its energy limits. Due to the advent of nonvolatile memories like PCM, MRAM, RRAM,(More)
This Image processing plays a vital role in complex image manipulation and understanding more feasible. it can be used either in a general manner or in specific domains such as medical, satellite. But we are facing the problem in unconnected image processing .Software, the article proposes a web based on line image processing software architecture with(More)

Robotic manipulators are subjected to both structured and unstructured uncertainties even in a well-structured setting. This paper attempts to design a fuzzy logic controller for controlling the position of the arms of a two-link manipulators taking into account the disturbances caused by inertial loading, coupling reaction forces between joints (Coriolis(More)
