Today, virtualization technologies and hypervisors celebrate their rediscovery. Especially migration of virtual machines (VMs) between hardware platforms provides a useful and cost-e ective means to manage complex IT infrastructures. A challenge in this context is the virtualization of hardware security modules like the Trusted Platform Module (TPM) since the intended purpose of TPMs is to secu...

We compute liftings of the Nichols algebra of a Yetter-Drinfeld module of Cartan type B2 subject to the small restriction that the diagonal elements of the braiding matrix are primitive nth roots of 1 with odd n 6= 5. As well, we compute the liftings of a Nichols algebra of Cartan type A2 if the diagonal elements of the braiding matrix are cube roots of 1; this case was not completely covered i...

In the last years we have seen a significant growth in the number of multidisciplinary projects between computer science and medicine. The computer science development and the continuous growth of confidence in its products are some relevant factors to rise in this cooperation. This project was born three years ago, from an association between Instituto Superior Técnico and Hospital de Santa Ma...

In this paper, a force-controllable compact actuator module for a wearable hand exoskeleton system is proposed. To interact with virtual objects naturally with a hand exoskeleton, a small actuator module, which can generate the desired force accurately, is highly required. In the proposed actuator module, a series elastic actuator (SEA) mechanism was applied for the force mode control. Based on...

B. Magajna and J. Schweizer showed in 1997 and 1999, respectively, that C*-algebras of compact operators can be characterized by the property that every norm-closed (and coinciding with its biorthogonal complement, resp.) submodule of every Hilbert C*-module over them is automatically an orthogonal summand. We find out further generic properties of the category of Hilbert C*-modules over C*-alg...

The last years have been a period of significant change and evolution in the Intelligent Virtual Environments (IVE) field, which combines Artificial Intelligence and Virtual Reality. Recently, there have been some efforts on developing interactive storytelling systems with dynamically generated behaviors of the participating virtual characters. Such systems however, lack the capability of a dec...

INTRODUCTION Developments in technology, web-based teaching and whole slide imaging have broadened the teaching horizon in anatomic pathology. Creating online learning material including many types of media such as radiologic images, whole slides, videos, clinical and macroscopic photographs, is now accessible to most universities. Unfortunately, a major limiting factor to maintain and update t...
