It is well known that some XML elements correspond to objects (in the sense of object-orientation) and others do not. The question we consider in this paper is what benefits we can derive from paying attention to such object semantics, particularly for the problem of keyword queries. Keyword queries against XML data have been studied extensively in recent years, with several lowest-common-ances...

Overview: Effective portfolio management is vital to maximizing the value of business’ new product development (NPD) portfolio; it also one weakest facets NPD. Ongoing evaluation tends be backward looking and process focused, business cases are not updated with real time more reliable data. A dynamic approach solution, including use Productivity Index (PI). Building in multiple iterations get r...

This paper presents a smoothing data association algorithm for a single target tracking in clutter. The proposed algorithm fuses the forward estimates and all the available measurement information retrodictions (but not backward track estimates) within the smoothing window to obtain the smoothed estimates. The measurement information retrodictions are obtained using the one-step-backward inform...

Abstract This paper applies a new approach to the identification of discourses, based on Multiple Correspondence Analysis (MCA), study discourse variation over time. The MCA keywords deals with major issue use identify discourses: allocation individual multiple discourses. Yet, as this demonstrates, also allows us observe in prevalence discourses texts patterns keyword co-occurrence. Metadata c...

In this study, we have designed and implemented a system that supports learners to use backward chaining to solve proof problems about the congruence of two triangles. In addition, we have carried out an evaluation experiment in a public junior high school to measure the learning effect of the system. As a result of hypothesis tests, for students with good pretest scores, the effect of the syst...
