Objectives: Rate controlis a very important factor in video coding. In video communications, rate control must ensure that the coded bit stream can be transmitted effectively and make full use of the narrow bandwidth. For various sequences the impact of rate control methods is examined and algorithm for rate controller for verification model version 8.0 for moving picture expert group-4 is defined. Methods/Statistical Analysis: In this work, Rate control analysis for H.263, MPEG-4 is fulfilled. For Rate control analysis of MPEG-4 test model, verification of model version 8.0 is followd. For H.263 Test Model Number 5 (TMN5), Test Model Number 8 (TMN8) and Test Model Number 12 (TMN12) are used. For various sequences is notice that the bit rate is varied and coefficient of correlation and peak signal to noise ratio is analyzed. Findings: In this work, Rate control analysis for H.263, MPEG-4 is fulfilled. Rate Control algorithm for MPEG-4 is developed. Influence of different rate control methods is analyzed and try to find which rate control methods i.e. C-1, C-2 and C-3 is suitable for which type of sequence specifications. Applications/Improvements: The performance evaluation is put forward for consideration in this work will activate the user analyzing experimental results of various rate control methods and how optimum rate-distortion will fulfilled for MPEG-4&H.263 video codec attained.Keywords

Manipur in India is endowed with rich biodiversity and abundant natural resources. Despite inaccessibility, marginality and heterogeneity, the state has made good progress in agriculture and allied sectors. About 80% of the state population depends on agriculture for livelihood. However, agriculture sector in Manipur is facing the consequences of climate change. Climate change is a reality and an increasing trend in temperature, precipitation and emission of greenhouse gases has been observed in Manipur. The state is also projected to experience more of extreme rainfall and reduction in crop yields. As subsistence level farming is coupled with prevalent shifting cultivation, the small and marginal farmers will be most affected due to climate change. Hence, there is an urgent need for devising climate proof plan and climate ready policy for climate compatible agricultural development in Manipur. Location-specific climate smart technology baskets need to be devised or introduced and should be demonstrated through participatory approach, for ensuring a climate resilient production system, and a climate resilient ecosystem. The interactions between the system’s adaptation strategies and the mitigation potential should also be given due importance in the action plan for combating climate change. This article deals with the present status of agriculture and allied sector and various technological and policy options for climate resilient agriculture in the hill and mountain ecosystems of Manipur.Keywords

Switchgear Testing and Development Station prevalently known as STDS was established in 1965 at Bhopal by the Government of India as one of the units of Central Power Research Institute. The predominant objective of setting up this institute was to cater the short-circuit testing needs of various LT/HT power equipments in switchgear, controlgear and transformer fi eld. Over the years, the unit has expanded and received all the national/international accreditations, and further became the member of Short Circuit Testing Liaison (STL). Today, CPRI’s short circuit laboratories of generator based and direct on-line based are one of the leading laboratories in south east Asia.
Year 2006–2007 was a test time for CPRI, Bhopal, when both the short-circuit generators have developed technical snag, resulting in an interruption of short-circuit testing. It was a challenge for CPRI as well as for the service provider to take repair work, as so many technical intricacies were involved including the reverse engineering process. Nation realized the importance of CPRI during the shutdown period. This paper discusses about the occurrence of failure, its detailed diagnosis, ischolar_main cause analysis and the action taken thereafter. Short-circuit generator is different from conventional one in many aspects. Repairing experiences of these generators, along with the re-commissioning process, are also shared herewith.
