Prediction of monsoon rainfall in a timely manner can be highly beneficial for Pakistan, where monsoon is the major source of rain. Presently, Multiple Linear Regression and Statistical Downscaling Models are being used for monsoon rainfall prediction. In spite of making use of a large number of resources and having dependency on a number of parameters, the results of these models have not been satisfactory...
The impact of ENSO (El-Nino/Southern Oscillation) on summer monsoon rain fall in southern parts of Pakistan is studied for deeply understanding the characteristics of summer rainfall variation and factors causing severe water shortages in already drought prone regions. The 16 stations data of summer rainfall, sea surface temperature and ENSO during 1951-2000 has been analyzed. The results comparing...
The use of organic materials in making polymeric insulators has many advantages. However, it also has a draw back that organic compounds degrade in outdoor environment by many factors. The major issue is that how long they will perform satisfactorily before the end of their useful life. This paper present the result of multistress lab aging on HTV SiR insulators. The environment used was of Islamabad,...
This study assesses the inter-annual variability of summer monsoon rainfall of Northern Hilly Area of Pakistan, which includes Balakot, Chitral, Murree, Gilgit, Skardu, Chilas, Muzaffarabad and Dir. The region receives a heavy rainfall, the total annual rainfall being 1000 mm or more. We attempt to model the rainfall process of the data from 1971-2000. Initially we use twelve predictors out of which...
Voice communication is effected by a number of factors especially the rain, as it causes the severe fading of the receive signal level. Fading is a function of frequency, polarization and path length and the actual amount of fading is dependent on the frequency of the signal and the size of the raindrop. This proposed outage prediction model is used not only to predict microwave radio link performance...
