The designed service life of Hong Kong-Zhuhai-Macao Bridge is 120 years. Concrete quality control for the submerged tunnel of the project is an important work to assure the designed service life. This article is to present an advanced concrete performance prediction method based on water–binder ratio (w/b) monitoring, which is used to serve for concrete quality control. During experiments in th...

This study was conducted to evaluate the performance of black gram (Vigna mungo.L) grown under drought stress using coir waste manure and cow dung manure. Two varieties of black gram-ATD mash 3 and ATD mash 1 were the treatment variables. A best fit positive relationship existed between leaf chlorophyll and leaf nitrogen content with two organic manures. N, P and K accumulation in the two varie...

A. Winman, P. Wennerholm, and P. Juslin (2003) have admitted that J. K. Kruschke (2001a) cogently demonstrated the shortcomings of eliminative inference as an explanation of the inverse base rate effect, but they raise criticisms of Kruschke’s attentionally based explanation. First, Winman et al. pointed out that attentional shifting does not improve learning performance in Kruschke’s (1996) AD...

Receiver Operating Characteristic (ROC) curve is used to assess the discriminatory power of credit rating models. To identify the optimal threshold on the ROC curve, the iso-performance lines are used. The ROC curve and the iso-performance line assume equal classification error costs and that the two classification groups are relatively balanced. These assumptions are unrealistic in the applica...

The U-curve optimization problem is characterized by a decomposable in U-shaped curves cost function over the chains of a Boolean lattice. This problem can be applied to model the classical feature selection problem in Machine Learning. Recently, the U-Curve algorithm was proposed to give optimal solutions to the U-curve problem. In this article, we point out that the U-Curve algorithm is in fa...

solute transport processes are affected by soil pore water velocity distribution. pore size distribution, which can be used to infer pore water velocity distribution, can be estimated from a soil water retention curve (n). in this study, a solute breakthrough curve was simulated using soil hydraulic parameters in four different soils. to evaluate the proposed model, predictions were compared to...

Receiver Operating Characteristic (ROC) analysis is a common tool for assessing the performance of various classification tools including biological markers, diagnostic tests, technologies or practices and statistical models. ROC analysis gained popularity in many fields including diagnostic medicine, quality control, human perception studies and machine learning. The area under the ROC curve (...

One of the challenges of modern information retrieval is to adequately evaluate Information Retrieval System (IRS) in order to estimate future performance in a specified application domain. Since there are many algorithms in literature the decision to select one for usage depends mostly on the evaluation of the systems’ performance in the domain. This paper presents how visual and scalar evalua...

We highlight a new algorithm for evaluating the surface intersection curve using a matrix formulation. The projection of the intersection curve is represented as the singular set of a bivariate matrix polynomial. The resulting algorithm for evaluating the intersection curve is based on matrix computations like eigendecomposition and singular value decomposition. Furthermore, at each stage of th...

The use of an alphabet of line segments to compose a curve is a possible approach for curve data compression. Curves having more sophisticated topology with self-intersections can be handled by methods considering recursive decomposition of the canvas containing the curve. We propose a graph theory based algorithm for tracing the curve directly to eliminate the decomposition needs. This approac...
