Some quality characteristics are well defined when treated as response variables and are related to some independent variables. This relationship is called a profile. Parametric models, such as linear models, may be used to model profiles. However, in practical applications due to the complexity of many processes it is not usually possible to model a process using parametric models.In these cas...

Rapid and precise effort estimation of software development projects is crucial in IT industry. In a case study, the Use Case Point (UCP) method was applied to 15 commercial software development projects. The estimated efforts were compared with the incurred project efforts. We measured a standard deviation of 42 %. This is not acceptable for industrial usage. Therefore, we propose appropriate ...

Until now we have considered the estimation of the value of a S/TRF at one point at the time, independently of the estimated values at other estimation points, i.e. a single-point mapping approach. The Bayesian Maximum Entropy (BME; Christakos, 1990, 1992) method offers a framework where the prediction of a S/TRF at several estimation points may be considered jointly, which is referred to as a ...

detention rockfill dams are an easy and common tool for flood control. due to their coarse pores, the flow in void spaces is turbulent and non-darcy. different relationships introduced by researchers are used to define the hydraulics of the flow within the rockfill materials. the present research is aimed at gaining a better understanding of the differ-ence among these relationships and the sou...

We propose a new method for the estimation of a 3D shape of non-convex object from an image sequence taken with the object rotating under a fixed light source. First, all the territory candidate of the object is prepared in voxel space. The empty voxels are selected by using the cross-section estimation using a silhouette that is the conventional method. In this method, we think a ray that conn...

The process personnel always seek the opportunity to improve the processes. One of the essential steps for process improvement is to quickly recognize the starting time or the change point of a process disturbance. Different from the traditional normally distributed assumption for a process, this study considers a process which follows a gamma process. In addition, we consider the possibility o...

A new method of pointwise adaptation has been proposed and studied in Spokoiny (1998) in context of estimation of piecewise smooth univariate functions. The present paper extends that method to estimation of bivariate grey-scale images composed of large homogeneous regions with smooth edges and observed with noise on a gridded design. The proposed estimator f̂(x) at a point x is simply the avera...

Multi−frame motion estimation is a new specificity of the video coding standard H.264/MPEG−4 Advanced Video Coding (AVC) to improve compression performances. These reference frames can be short or long−term. However, a long−term motion estimation needs to have a good initial search point to be effective. In this paper, we propose a new method for a fast long−term motion estimation with high def...

Software cost estimation is a crucial part of the software project initiation process. Cost estimation plays an important role in the bidding/budgeting and help managers to use their resources at the maximum output level. Software Project failure rate is very high in case the project cost estimation is not done by taking all the important factors into the consideration. So finding the cost at t...
