Authoring and editing processes in wiki systems are often tedious. Sheer amount of information makes it difficult for authors to organize the related information in a way that is easily accessible and retrievable for future reference. Social bookmarking systems provide possibilities to tag and organize related resources that can be later retrieved by navigating in so-called tag clouds. Usually,...

A successful grasp of an object can be guaranteed when the object can never escape from the surrounding fingers during the entire grasping execution. Ability to capture an object clearly contributes to the robustness and success of grasping tasks. Object concavity is a useful geometric property allowing objects to be captured with only few fingers. In particular, certain concave objects may be ...

In [9, 10], Hartshorne gives an account of the known vector bundles of "small" rank on P" and also on the punctured spectrum of a regular local ring. Specifically, he remarks on various constructions of rank two vector bundles on P", for n ^ 4, and Horrocks' examples [12] of rank three bundles on P as well. The result of Evans and Griffith [7] on syzygies shows that the existence of rank two in...

This article proposes a framework for conceptualizing developing as a critically re ̄ective teacher. The author posits that critical re ̄ection is the distinguishing attribute of re ̄ective practitioners. The term critical re ̄ection as developed here merges critical inquiry, the conscious consideration of the ethical implications and consequences of teaching practice, with self-re ̄ection, deep exa...

We give some constructions of new infinite families of group divisible designs, GDD(n, 2, 4; 1, 2), including one which uses the existence of Bhaskar Rao designs. We show the necessary conditions are sufficient for 3 n 8. For n= 10 there is one missing critical design. If 1> 2, then the necessary conditions are sufficient for n ≡ 4, 5, 8 (mod 12). For each of n=10, 15, 16, 17, 18, 19, and 20 we...

Overview The structure of these patterns is similar to the one introduced by Andreas Rueping [6] . The problem section formulates an issue as a question. The forces are the considerations that lead to the solution. The solution answers the question of the problem section. In the discussion section, some examples are presented or drawbacks of the solution are discussed. Some of the patterns have...

In this paper, the authors demonstrate the suitability of IT-supported knowledge repositories for knowledge retention. Successful knowledge retention is dependent on what is stored in a repository and, hence, possible to share. Accordingly, the ability to capture the right (relevant) knowledge is a key aspect. Therefore, to increase the quality in an IT-supported knowledge repository, the ident...

The REQUESTSJNFO type encapsulates all information necessary for routing and scheduling requests for critical section

In machines with weak memory consistency models , the ordering constraints on memory accesses are few. In order to properly program these machines, certain powerful explicit synchronization instructions are additionally provided by their architecture. We show that although a solution to the critical section problem (also referred to as the mutual exclusion problem) is impossible without such po...

Main Results: Of the 23 articles examining the effects of an acute bout of stretching, 22 articles suggested that there was no benefit for the outcomes isometric force, isokinetic torque, or jumping height. There was 1 article that suggested improved running economy. Of 4 articles examining running speed, 1 suggested that stretching was beneficial, 1 suggested that it was detrimental, and 2 had...
