the polynomial interpolation in one dimensional space r is an important method to approximate the functions. the lagrange and newton methods are two well known types of interpolations. in this work, we describe the semi inherited interpolation for approximating the values of a function. in this case, the interpolation matrix has the semi inherited lu factorization.

After an introduction to main ideas of semi-infinite optimization, this article surveys recent developments in theory and numerical methods for standard and generalized semi-infinite optimization problems. Particular attention is paid to connections with mathematical programs with complementarity constraints, lower level Wolfe duality, semi-smooth approaches, as well as branch and bound techniq...

در تحقیق حاضر، با استفاده از ترکیب تئوری dsd و روش level set جبهه تراک تعقیب شده است. نخست، با استفاده از یک کد dsd یا از طریق مراجع، روابط d-? و d ?-d-? برای مواد شدیدالانفجار و مخلوط های گازی به دست آورده شده است، سپس با استفاده از روش level set، جبهه تراک در هندسه های مختلف تعقیب شده است. برای مواد شدیدالانفجار که در آن ها انحنا نقش مهمی را در دینامیک جبهه تراک دارد، همخوانی خوبی بین نتایج ت...

Semi-supervised clustering approaches have emerged as an option for enhancing clustering results. These algorithms use external information to guide the clustering process. In particular, semi-supervised hierarchical clustering approaches have been explored in many fields in the last years. These algorithms provide efficient and personalized hierarchical overviews of datasets. To the best of th...

In opinion mining, there has been only very little work investigating semi-supervised machine learning on document-level polarity classification. We show that semi-supervised learning performs significantly better than supervised learning when only few labeled data are available. Semi-supervised polarity classifiers rely on a predictive feature set. (Semi-)Manually built polarity lexicons are o...

Semi-Autonomous Systems (SAS) describe a class of systems that are explicitly controlled by both human and agent actors, incorporating the distinct capabilities of each. They are designed for domains that require quick and safe transfer of control between the agent and human, and embed control transfer decisions in the overall high-level plan. We formally define SAS as a hierarchical model and ...

Semi-structured data has become prevalent with the growth of the Internet and other on-line information repositories. Many organizational databases are presented on the web as semi-structured data. Designing a \good" semi-structured database is increasingly crucial to prevent data redundancy, inconsistency and updating anomalies. In this paper, we deene a semi-structured schema graph and identi...

Each closed oriented 3-manifoldM is naturally associated with a set of integersD(M), the degrees of all self-maps on M . D(M) is determined for each torus bundle and torus semi-bundle M . The structure of torus semi-bundle is studied in detail. The paper is a part of a project to determine D(M) for all 3-manifolds in Thurston’s picture.
