There exists a number of semi-empirical relationships assessing void ratio in the literature. The predictive performances of widely used void ratio relationships are assessed within a probabilistic framework with the use of compiled database. The database, which consists of 636 non-plastic silts, sands, and gravels is compiled from the existing literature having minimum, maximum void ratio, mean grain size, coefficient of uniformity, particle roundness and sphericity, fines content parameters. Among predictive models, which use D-50 as an input parameter, Chen and Kulhawy model produced the least error (mu(error)=-0.006, sigma(error)=0.125) and is concluded to be more accurate compared to Cubrinovski and Ishihara model (mu(error)=-0.055, sigma(error)=0.140). Similarly, Zheng and Hycriw, which uses C-u as an input parameter produced more accurate predictions (mu(error)=-0.034, sigma(error)=0.069), when compared to Chen and Kulhawy model (mu(error)=-0.062, sigma(error)=0.137).

The moment function for the ratio of correlated generalized gamma variables Candan, Çağatay; Orguner, Umut (Elsevier BV, 2013-10) The moment function for the ratio of correlated generalized gamma variables is expressed in terms of special functions. The expression presented generalizes the known moment expression for the integer valued moments to the real valued moments. Approximate formulas, in terms of elementary functions, are provided for low and high correlation regions and some application examples are given.
Analytical solution and experimental verification of shaped charge jet penetration Gozubuyuk, Serkan; Yıldırım, Raif Orhan (2006-07-07) In the scope of this study a one dimensional shape charge code was developed using analytical and semi-empirical approaches. The penetration part of the code is based on the hydrodynamic theory of penetration. The code is capable of modeling and visualizing of shaped charge liner collapse, jet formation and target penetration. Factors affecting the penetration were investigated by utilizing the developed code. Since the code is based on the solution of some analytical expressions rather than the solution of...
A Hilbert Space of Probability Mass Functions and Applications on the Sum-Product Algorithm Bayramoglu, Muhammet Fatih; Yılmaz, Ali Özgür (2008-09-05) In this paper a Hilbert space structure of probability mass functions (PMF) will be presented. The tools provided by the Hilbert space, specifically the norm and the inner product, may be useful while analyzing and improving the sum-product algorithm in many aspects. Our approach provides a metric distance between PMFs and a new point of a view of the log-likelihood ratio (LLR) such that the LLR representation is nothing but a Hilbert space representation.
A statistical approach to sparse multi-scale phase-based stereo Ulusoy, İlkay (Elsevier BV, 2007-09-01) In this study, a multi-scale phase based sparse disparity algorithm and a probabilistic model for matching uncertain phase are proposed. The features used are oriented edges extracted using steerable filters. Feature correspondences are estimated using phase-similarity at multiple scale using a magnitude weighting scheme. In order to achieve sub-pixel accuracy in disparity, we use a fine tuning procedure which employs the phase difference between corresponding feature points. We also derive a probabilistic ...
A Probabilistic approach to sparse multi scale phase based stereo ULUSOY PARNAS, İLKAY; Halıcı, Uğur; HANCOCK, EDWIN (2004-04-30) In this study, a multi-scale phase based sparse disparity algorithm and a probabilistic model for matching are proposed. The disparity algorithm and the probabilistic approach are verified on various stereo image pairs.
