This paper proposes two sampling strategies based on the modified ratio estimator using the population mean of auxiliary variable and population correlation coefficient between the study variable and the auxiliary variable by Singh and Tailor (2003) for estimating the population mean (total) of the study variable in a finite population. A comparative study is made with usual sampling strategies...

In this paper we present an analysis of the storage complexity of Huffman codes, Tunstall codes and arithmetic codes in various implementations and relate this to the achieved redundancies. It turns out that there exist efficient implementations of both Huffman and Tunstall codes and that their approximations result in arithmetic codes. Although not optimal, the arithmetic codes still have a be...

due to the complex structure of the pressure-adjusting device used in most sprinklersfor variable irrigation, it is not possible to observe the flow behavior of the water passingthrough the flow field. in this paper, an integral three dimensional (3d) numerical modelbased on the structural characteristics of the fluidic sprinkler was constructed to simulatethe flow field distribution using comp...

in financial distress studies selection of variable is commonly basedon the success of variables in variable sets employed in earlierbankruptcy studies, suggestions in the literature or an accompanyingdata reduction in a large set of variables. if seemingly different variablesets exhibit a strong relationship then heterogeneous variable setscapture common information. canonical correlation anal...
