Current anonymous systems either use a small, fixed core set of mixes or randomly choose a sequence of peer nodes to form anonymous paths/tunnels. The resulting paths are fragile and shortlived — that is, a path fails if one of the mixes/nodes fails or leaves the system. In this paper, we propose SurePath, a failure-resilient tunneling approach for anonymity built on distributed hash tables (DH...

In this paper, we consider configurable capacity tunnels. Static bandwidth allocation (SBA) assigns the network capacity to the tunnels according to the busy hours of their traffic aggregates. At secondary times, their capacity is underutilized and can not be used to accommodate excess traffic of other tunnels. The contribution of this paper is twofold. Firstly, we propose two mechanisms for ad...

BACKGROUND Little is known about surgeon agreement and accuracy using arthroscopic evaluation of anterior cruciate ligament (ACL) tunnel positioning. PURPOSE To investigate agreement on ACL tunnel position evaluated arthroscopically between operating surgeons and reviewing surgeons. We hypothesized that operating and evaluating surgeons would characterize tunnel positions significantly differ...

There are many mountains in the longitudinal center of Taiwan, which slow down transportation between the west and east in Taiwan. In order to solve this problem, Taiwan’s government decided to build a highway and an expressway between these two areas, which would include tunnels as part of the project because tunnels are more dangerous than the open road, how to safely enter, pass and leave tu...

One of the options for creating a Deep Underground Science and Engineering Laboratory (DUSEL) is a site in the Mt. Stuart batholith, a granodiorite and tonalite rock mass in the Cascade mountain range in Washington State. The batholith’s 100-year history in hard-rock tunneling includes the construction of the longest and deepest tunnels in the U.S., the parallel Cascade and Pioneer tunnels. The...

Tunnels are 3D graphical sliders which modify the appearance of, or ”modulate”, one or several 3D objects simultaneously using these objects as cursors themselves. They rely on a strong visual feedback to provide multiple scales and parameters combinations which makes them appropriate for the use in immersive virtual musical instruments. In this paper we present applications of the Tunnels for ...

IPv6 is the future network layer protocol for the Internet. Since it is not compatible with its predecessor, some interoperability mechanisms were designed. An important category of these mechanisms is automatic tunnels, which enable IPv6 communication over an IPv4 network without prior configuration. This category includes ISATAP, 6to4 and Teredo. We present a novel class of attacks that explo...

This document describes a common practice on how the existing metric of Interior Gateway Protocols (IGP) can be used as an alternative metric to the Traffic Engineering (TE) metric for Constraint Based Routing of MultiProtocol Label Switching (MPLS) Traffic Engineering tunnels. This effectively results in the ability to perform Constraint Based Routing with optimization of one metric (e.g., lin...

The harvester termite, Baucaliotermes hainesi (Fuller) (Termitidae: Nasutitermitinae), is an endemic in southern Namibia, where it collects and eats dry grass. At the eastern, landward edge of the Namib Desert, the nests of these termites are sometimes visible above ground surface, and extend at least 60 cm below ground. The termites gain access to foraging areas through underground foraging tu...
