Recently, many authors have considered the problem of simultaneous lo-calisation and mapping (SLAM). The paper addresses a somewhat diierent problem, that of cooperative localisation and mapping (CLAM). Basically, CLAM involves two or more robots cooperating to build a map of the environment. This cooperation is not aimed at simply increasing the speed with which the map is constructed; rather,...

In this paper we critically review and analyze previous research on collaborative concept mapping in both face-to-face and networked environments. Although research has shown the positive effects of collaborative concept mapping on learning in face-to-face learning environments, there is a dearth of research which specifically focuses on the potential value of adopting collaborative concept map...

Concept mapping is a valuable technique for education evaluation. This paper describes a system which supports teachers in creating concept mapping tasks which are intended to capture the student’s understanding of the ontology of a small domain. A novel feature of our work is that the system verifies that the student intended the map elements that will be used to infer student understanding an...

In this paper we prove existence of fixed point theorems for Z-contractive map, Geraghty type contractive map and interpolative Hardy-Rogers type contractive mapping in the setting of SJS- metric spaces with two metrics. Examples are constructed to high light the significance of newly obtained results.

The concept mapping and the Vee diagram are important tools for improving the level of conceptual learning of mathematics in all educational levels that can play an important role in the learner's achievement. The purpose of this study is to use a concept mapping and Vee diagram, to calculate the volume of an object by the integral, includes the reaction of what a teacher really knows, the way ...

This study was an attempt to investigate the comparative impact of concept map and mind map instruc- tion on EFL learners’ descriptive and narrative writing. To fulfill this purpose, 60 intermediate EFL learners were selected from among a total number of 100 through their performance on a pretest, i.e., a piloted sample Cambridge Preliminary English Test (PET). T...

This study proposes a web-based collaborative inquiry learning system. This system uses the Worldwide web (WWW) as a source of knowledge exploration, and provides exploratory problems to guide students to think and explore. A concept map is used as a tool of anchoring and representing knowledge during inquiry process. In the process of learning, learners are allowed to exchange the evidence the...

Large scale 3D maps constructed via LiDAR sensor are widely used on intelligent vehicles for localization in outdoor scenes. However, loading, communication and processing of the original dense time consuming onboard computing platform, which calls a more concise representation to reduce complexity but keep performance localization. In this paper, we propose teacher-student learning paradigm co...
