In the arena of, high speed data transmission and requirement of large data to store in minimum available space, compression is very prominent aspect. There are various techniques, which have been applied for this purpose. One of most useful technique is fractal image compression. In which the main errand is to lessen the transmission time and storage capacity. In this paper, the primary object...

the object of this paper is to establish a summability factor theorem for summabilitya, , k  1 k  where a is the lower triangular matrix with non-negative entries satisfying certain conditions.

we obtain sufficient conditions for the series σanλn to be absolutely summable of order k by atriangular matrix.

The study aimed to compare the hip joint position sense (JPS) of patients undergoing conventional total hip arthroplasty (THA) or hip resurfacing arthroplasty (HRA). A total of 40 patients who underwent hip arthroplasty (20 THA and 20 HRA) for unilateral coxarthrosis in our department from January 2008 to July 2009 were reviewed. Both groups of patients were matched in age, gender, body-mass in...

This work incorporates the identification of model in functional form using curve fitting and genetic programming technique which can forecast present and future load requirement. Approximating an unknown function with sample data is an important practical problem. In order to forecast an unknown function using a finite set of sample data, a function is constructed to fit sample data points. Th...

background: water is considered as the main source of life but water resources are limited and nonrenewable. different factors have caused groundwater to decrease. therefore, modeling and predicting groundwater level is of great importance. methods: monthly groundwater level data of about 20 years (october 1991 to february 2012) from the hamadan-bahar plain, west of iran were used based on peiz...

The classical strategy to evaluate the performance of a Recommender System is to measure the error in rating predictions. But when focusing on a particular dimension in a recommending process it is reasonable to assume that every prediction should not be treated equally, its importance depends on the degree to which the predicted item matches the deemed dimension or feature. In this paper we sh...

In the paper a relatively simple yet powerful and versatile technique for forecasting time series data – simple exponential smoothing is described. The simple exponential smoothing (SES) is a short-range forecasting method that assumes a reasonably stable mean in the data with no trend (consistent growth or decline). It is one of the most popular forecasting methods that uses weighted moving av...
