A novel optimal fuzzy color image enhancement using particle swarm optimization

Abstract: This paper presents a new approach to enhance the contrast of color images. The intensity component of Hue, Saturation and Intensity (HSV) color model is fuzzified using Global intensification operator (GINT). A new objective measure called contrast information factor is introduced which is optimized using particle swarm optimization technique to learn the parameters. The enhanced image is evaluated by its entropy, index of fuzziness, contrast information and visual quality factor. Subjective and objective evaluation results clearly show the improvement in the quality of the underexposed images in addition of preserving color and specific image features. Also the shape of the histogram is preserved. The results are also compared with histogram equalization technique.

Fuzzy based multilevel queue scheduling algorithm

Abstract: Many scheduling techniques has been designed for scheduling of processes in the multiprogramming system, one of these techniques is multilevel queue CPU scheduling technique where the ready queue is divided into multiple sub-queues. Processes are assigned to different sub queues depending on their classification. In traditional multilevel queue scheduling approach each queue is assigned a priority level. Processes from the higher level queues always gets priority over the processes in lower level queues which can cause starvation for processes in lower queues. In this paper we propose a new fuzzy based multilevel queue CPU scheduling algorithm. In our proposed work ready queue is divided into two sub-queues which contain I/O bound and CPU bound processes. CPU time is allocated dynamically to each queue. We have designed two fuzzy inference systems. One is to dynamically allocate the CPU time to two queues. Another FIS is designed to calculate the time quantum to schedule the I/O bound processes. Our proposed work improves the starvation problem and the average response time.

Navigation with Indian Constellation and its Applications in Metrology

Abstract: Navigation with Indian Constellation (NavIC), also known as Indian Regional Navigation Satellite System (IRNSS), is an independent regional navigation satellite system, designed to provide accurate position information in the Indian subcontinent. Precise time plays a crucial role in any satellite navigation system for providing positioning, navigation and timing services. IRNSS Network Timing Facility (IRNWT), located at the control center of NavIC, caters to the precise timing requirements of NavIC network. A major metrological application of IRNWT and hence of NavIC is to provide time & frequency calibration with very high accuracy. To ensure traceability to the national reference, UTC (NPLI), and through it to the apex reference, UTC, the IRNWT time scales are linked with the UTC (NPLI), realized at CSIR—National Physical laboratory, India (NPLI) using GNSS Common-view (CVGNSS) and two-way satellite time and frequency transfer techniques. This paper discusses how NavIC plays an effective role in the dissemination of Indian Standard Time or UTC (NPLI) to the users in its service volume. Also discussed are the typical results of traceability of IRNWT time scales to the national reference.
