A production plan, which describes how core assets are used to develop products, has an important role in product line engineering as a communication medium between core asset developers and product developers. Recently, there have been efforts to address issues related to production planning; however, most of them focus on the process and business/management aspects of production planning, and...

Existing economic models support the estimation of the costs and benefits of developing and evolving a Software Product Line (SPL) as compared to undertaking traditional software development approaches. In addition, Feature Diagrams (FDs) are a valuable tool to scope the domain of a SPL. This paper proposes an algorithm to calculate, from a FD, the following information for economic models: the...

An efficient and general framework for the incorporation of statistical prior information, based on a wide variety of detectable point features, into level set based object tracking is presented. Level set evolution is based on the maximisation of a set of likelihoods on mesh values at features, which are located using a stochastic sampling process. This evolution is based on the interpolation ...

we present a detailed analysis of the static tuning characteristics of three section tunable distributed bragg reflector (dbr) laser. the analysis is based on the transfer matrix method (tmm), transmission line and scattering theory. the key feature of the analysis is the use of modified oscillation condition. with the exact oscillation condition, the static tuning characteristics such as thres...

In this article, we identify that partial, vague and conflicting information can severely limit the effectiveness of approaches that derive feature trees from textual requirement specifications. We examine the impact such imperfect information has on feature tree extraction and we propose the use of fuzzy feature diagrams to address the problem more effectively. This approach is then discussed ...

In this paper we present an approach in which an on-line handwritten character is characterized by a sequence of dominant points in strokes and a sequence of writing directions between consecutive dominant points. The directional information is used for character preclas-siication and the positional information is used for ne classiication. Both preclassiication and ne classiication are based o...

We consider the problem of resequencing a pre-arranged set of jobs on a moving assembly line with the objective of minimizing changeover costs. A changeover cost is incurred whenever two consecutive jobs do not share the same feature. Features are assigned from a set of job-specific feasible features. Re-sequencing is limited by the availability of offline buffers. The problem is motivated by a...

This paper points out and analyzes the advantages and drawbacks of the Nearest Feature Line (NFL) classifier. To overcome the shortcomings, a new feature subspace with two simple and effective improvements is built to represent each class. The proposed method, termed Rectified Nearest Feature Line Segment (RNFLS), is shown to possess a novel property of concentration as a result of the added li...

Feature lines are perceptually salient features on 3D meshes. They are of interest for 3D shape description, analysis and recognition. Their detection is a necessary step in several feature sensitive mesh processing applications such as mesh simplification, remeshing or non-photorealistic rendering. In this paper, an estimator for the angle between tangent plane normals is introduced and a new ...
