In an edge-colored graph, a traversal cost occurs at a vertex along a path when consecutive edges with different colors are traversed. The value of the traversal cost depends only on the colors of the traversed edges. This concept leads to two global cost measures, namely the reload cost and the changeover cost, that have been studied in the literature and have various applications in telecommu...

We study the minimum diameter spanning tree problem under the reload cost model (DiameterTree for short) introduced by Wirth and Steffan (2001). In this problem, given an undirected edge-colored graph G, reload costs on a path arise at a node where the path uses consecutive edges of different colors. The objective is to find a spanning tree of G of minimum diameter with respect to the reload co...

Besides cryptographic secrets, side-channel attacks also leak sensitive user input. The most accurate attacks exploit cache timings or interrupt information to monitor keystroke timings and subsequently infer typed words and sentences. Previously proposed countermeasures fail to prevent keystroke timing attacks as they do not protect keystroke processing among the entire software stack. We clos...

We define a RELOAD Usage for Application Layer Multicast as well as a mapping to the RELOAD experimental message type to support ALM. The ALM Usage is intended to support a variety of ALM control algorithms in an overlay-independent way. Two example algorithms are defined, based on Scribe and P2PCast. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, repl...

In this paper, we propose a timing analysis approach for preemptive multi-tasking real-time systems with caches. The approach focuses on the cache reload overhead caused by preemptions. The Worst Case Response Time (WCRT) of each task is estimated by incorporating cache reload overhead. After acquiring the WCRT of each task, we can further analyze the schedulability of the system. Four sets of ...

In this paper we consider the notion of “reload costs” in network design. Reload costs occur in telecommunication networks using diverse technologies. For example, one of the products offered by commercial satellite service providers and their partners is a virtual private network (VPN) that can offer voice, video and data connectivity between all of the geographically dispersed locations of la...

Sum mary: The term “flush” is a misnomer for diverse physiological and pathological medical conditions; however, simple flush can signify the presence of a serious underly ing medical condition. Many patients with non-carcinoid facial flush have been refer red to our department as cases of carcinoid flush. Most of these patients had already undergone many bio chemical and radiological workups, ...
