in order to promote and improve the quality of educational spaces and achieving a comprehensive statistics, evaluation and analysis of schools neglected in most iran’s schools,  while educational spaces play an important role in the social and cultural structure and population growing and schools as one of the most basic educational centers, study on this field is important. therefore, schools ...

Abstract We study homogeneous Einstein metrics on indecomposable non-Kahler C-spaces, i.e. even-dimensional torus bundles M = G ∕ H with rank > over flag manifolds F K of a compact simple Lie group . Based the theory painted Dynkin diagrams we present classification such spaces. Next focus family l , m n ≔ SU ( + ) × ∈ Z and examine several its geometric properties. show that invariant are not ...

The paper presents the work of the Elena project. The contribution of this paper is twofold: The first part of the paper elaborates on the notion of educational services. Educational services are differentiated from learning objects and put in context of web services. A model for educational services is introduced and current limitations of metadata standards are addressed. In the second part o...

Abstract We identify a geometric relation between the Laplace–Beltrami spectra and eigenfunctions on compact Riemannian symmetric spaces Borel–Weil theory using ideas from symplectic geometry quantization. This is done by associating with each space, via Marsden–Weinstein reduction, generalized flag manifold that covers space parametrizing all of its maximal totally geodesic tori. In process, w...

This paper describes a new method for visualizing complex information spaces as painted images. Scientific visualization converts data into pictures that allow viewers to “see” trends, relationships, and patterns. We introduce a formal definition of the correspondence between traditional visualization techniques and painterly styles from the Impressionist art movement. This correspondence allow...

'Space and place are central to the strategies and meaning of protest’ (p. xi) reads the opening sentence of Katrina Navickas's latest study, Protest and the Politics of Space and Place 1789–1848. Written, in part, as a response to the 'spatial turn' in History, Navickas makes a cogent and persuasive argument for attending to the importance of the particularities of 'place' rather than the abst...

Real time computer graphics are limited in that they can only be displayed on projection screens and monitors. Monitors and projection screens cannot be used in live fire training or scenarios in which the displays could be physically damaged by trainees. To address this issue, we have developed projection systems using computer vision based color correction and image processing to project onto...

In order to make optimal educational use of social spaces offered by thousands of international communities in the second generation web applications termed Web 2 or Social Web, ICT competences as well as social skills are needed for both teachers and learners. The paper outlines differences in competence structures of Net Natives (who came of age in the 21st century) and the Net Generation of ...
