Immersive Group-to-Group Telepresence

IEEE Transactions on Visualization and Computer Graphics, 2013
We present a novel immersive telepresence system that allows distributed groups of users to meet in a shared virtual 3D world. Our approach is based on two coupled projection-based multi-user setups, each providing multiple users with perspectively correct stereoscopic images.

A group in a group

Algebra and Logic, 1990
A stable theory \(T\) is said to be weakly normal if, for every model \(M\) of \(T\), every subset \(A\) of \(M\) and every element \(b\) in \(M\), the canonical basis of \(t(b/A)\) is algebraic over \(A\cup b\). It is known that, if \(T\) is a superstable theory of finite rank, \(T\) is weakly normal if and only if all rank-one types have a locally ...

Women in Group and Women’s Groups

International Journal of Group Psychotherapy, 2002
Female development is characterized by the introjection of maternal and paternal objects, which creates a rich internal world for women. However, the feminine tendency to become diffused in identifications sometimes results in women feeling overpowered in mixed-gender groups.

Groups And Groupings In The UN

2000
This chapter talks about groups and groupings in the UN. The day-to-day business of the United Nations is very much influenced by groups of states, which have combined to formulate group interests, and to attempt to impose their positions in the organizations and programmes.

{Groups, {Groups, {and More Groups}}}

1993
The concept of gathering text into groups allows TEX input files to be greatly simplified. A new group is started by the character {and terminated by the character}. Changes made within a group will lose their effect when the group terminates. So, for example if {\bf three boldface words} appears in your text, the opening brace starts the group, the ...

The Automorphism Groups of the Braid Groups

American Journal of Mathematics, 1981
In the first of two papers published in the Annals in 1947 [3] Emil Artin mentioned the problem of determining all automorphisms of the braid groups (of the Euclidean plane), and in the second [4] took a first step towards a solution. The main result of this paper is a complete determination of these automorphism groups: the outer automorphism group is

ON THE CENTRE OF THE AUTOMORPHISM GROUP OF A GROUP

Bulletin of the Australian Mathematical Society, 2015
If the centre of a group $G$ is trivial, then so is the centre of its automorphism group. We study the structure of the centre of the automorphism group of a group $G$ when the centre of $G$ is a cyclic group. In particular, it is shown that the exponent of $Z(\text{Aut}(G))$ is less than or equal to the exponent of $Z(G)$ in this case.

To Group or Not to Group

The Clearing House: A Journal of Educational Strategies, Issues and Ideas, 1960
Fundamentally, it is impossible to escape some kind of grouping of students. At one end of the scale is random or what we call heterogeneous grouping. At the other end, there is ability or some other type of homogeneous grouping in all major subject areas. In between, it is a question of how much grouping for whom and in what subjects.
