saturation scans. (c) and (d): 2D phase correction leads to superior water-fat separation than 1D linear phase correction (arrows). (d) also shows the chemical shift induced ringing at water-fat interface when the opposite polarity data are not combined (dashed arrows) Figure 2: Calculated NSA for the flexible echo shift strategy, where last echo is fixed at 7π/6, while ΔTE is determined by the...

Flexible and efficient communication support is increasingly required by forthcoming applications, such as multimedia applications, interactive TV, or teleshopping. The communication subsystem presented in this paper is highly flexible due to its modular de-layered design. It consists of protocol building blocks that can be configured to servicetailored protocols according to the individual app...

The EAP-GPSK protocol is a lightweight, flexible authentication protocol relying on symmetric key cryptography. It is part of an ongoing IETF process to develop authentication methods for the EAP framework. We analyze the protocol and find three weaknesses: a repairable Denial-of-Service attack, an anomaly with the key derivation function used to create a short-term master session key, and a ci...

The spatially and temporally diverse nature of ad hoc networks strongly suggests the development of a sophisticated multi protocol network-layer that should enable the ad hoc network's nodes to dynamically change the routing protocol as networking scenarios demand. In short, the routing protocol is to be considered a system variable. However, the autonomous reconfiguration of such a dependent v...

Recent work on cross-layer schemes have demonstrated the need for a unifying wireless sensor networks architecture that provides more integration than the standard layered OSI protocol stack yet is flexible enough to support different applications. In this paper, we propose a new informationsharing architecture for sensor networks that can support existing protocols while simultaneously providi...

When BRCA1/2 genetic susceptibility testing was introduced in the clinic in the mid-nineties, the "Huntington protocol" was used in the counselling of individuals applying for genetic testing. This protocol includes at least three sessions with a certain reflection period before blood sampling. Evidence on the psychological impact of BRCA1/2 genetic susceptibility testing has been accumulating ...

In the context of Switched Ethernet, the Flexible Time-Triggered Switched Ethernet protocol (FTT-SE) was proposed to overcome the limitations and related problems of using COTS switches in real-time networks, such as overflow of switch queues due to uncontrolled arrival of packets. Although the FTT-SE protocol has been validated by several experiments on real applications, evaluation of differe...

A variety of business interactions in open environments can be captured in terms of the creation and manipulation of commitments among the agents. These include B2B contracts as realized via Web Services and other technologies. Also, the interaction protocols are formulated in terms of the commitments to regulate agents’ behaviors. However, such protocols can benefit from a stronger treatment o...

The Radio Link Control (RLC) protocol in Universal Mobile Telecommunication System (UMTS) contains a suite of features and options which make the protocol very flexible and adaptive to operation in different radio environments and for various applications. In this paper, we analyze the various features and functions associated with the RLC protocol and evaluate the performance over UMTS specifi...

data envelopment analysis (dea) has been proven as an efficient technique to evaluate the performance of homogeneous decision making units (dmus) where multiple inputs and outputs exist. in the conventional applications of dea, the data are considered as specific numerical values with explicit designation of being an input or output. however, the observed values of the data are sometimes imprec...
