Most of the mobile Adhoc network protocols are validated by simulation environment. The validation is meaningful when they use realistic movement mobility models, which directly impacts the performance of the protocols. Once the nodes have been initially distributed, the mobility model dictates the movement of the nodes within the network. If this movement(More)
In this paper for existing concurrent structure independent fault detection schemes with new technique for the fault detection of sub bytes and inverse sub bytes using the relation between the input and output of the S-box, the formulation of mix column are implemented for AES, which results in the reduction of area coverage and power consumption along with(More)
A Selection based Interference algorithm for efficient decoding of MC-MC-DS-CDMA Transceiver with Multipath Rayleigh fading is presented in this paper.The Interference Cancellation algorithm is capable of increasing signal strength and reducing probability of error using two stages of decoding namely , Selection phase and Threshold decoding phase .The(More)
X-ray mammography is the most widely used modality for screening breast cancer in the early stages. Computer aided detection (CADe) systems intend to help radiologists in improving the detection rate. However, the drawback of CADe systems is that they result in a high false positive rate (FPR). In this paper, a new feature-fusion-based system is proposed(More)
In this paper, the development of a 3-axis motion simulator is described. The simulator is used to test and calibrate certain spacecraft instruments within a hardware-in-the-loop environment. A mathematical electromechanical model of the simulator is developed. Moreover, a novel robust adaptive nonlinear control law for the simulator is developed based on(More)
The development of automotive electronics and software systems is often associated with high costs due to their multi-domain nature (including control engineering, electronics, hydraulics, mechanics, etc). The involvement of these different disciplines makes it difficult for control engineers to test their controllers with them being integrated in the whole(More)
the performance metrics obtained for different filter orders for both the architectures and the results reveal that both the designs have yielded significant improvement in speed. The most fundamental part used in many digital signal processing (DSP) applications is a finite impulse response filter because of its linear phase, stability and regular(More)
It is well known that sequential decoding techniques such as Enhanced Maximum Likelihood sequential decoding (EMLSD) technique can obtain significant performance improvement over conventional decoding techniques in multicarrier direct sequence Code Division Multiple Access (MC-DS-CDMA) systems. Due to its simplicity and usefulness the EMLSD has received(More)

The deviations in the injection orbital parameters, resulting from launcher dispersions, need to be corrected through a set of acquisition maneuvers to achieve the desired nominal parameters. When multiple satellites are injected into a single orbital plane, as a part of constellation establishment, they have to positioned in the plane with appropriate(More)
