Performance Analysis of Physical Layer Network Coding

Analysis of a planning domain has been shown to produce information that can greatly reduce the space of plans a controller must search through. Domain analysis is generally based on the logical inferences one can make given a set of planning operators and sometimes information about goals. An alternative heuristic approach is possible as well. We have developed a small set of physical schemas ...

Physical-layer Network Coding (PNC) makes use of the additive nature of the electromagnetic (EM) waves to apply network coding arithmetic at the physical layer. With PNC, the destructive effect of interference in wireless networks is eliminated and the capacity of networks can be boosted significantly. This paper addresses a key outstanding issue in PNC: synchronization among transmitting nodes...

We propose a general theoretical framework to analyze the security of Physical Uncloneable Functions (PUFs). We apply the framework to Optical PUFs. In particular we present a derivation, based on the physics governing multiple scattering processes, of the number of independent challengeresponse pairs supported by a PUF. We find that the number of independent challenge-response pairs is proport...

Many results in logic, in particular in computability theory and in model theory, express properties of sets of functions and sets of relations, such as the set of the polynomial functions, that of the computable functions, that of the relations definable by a formula in predicate logic, ... In particular, a part of the theory aims at constructing languages to express the functions and the rela...

Recent initiatives that evaluate the security of physical systems with objects as assets and people as agents –here called Socio-Technical Physical Systems– have limitations: their agent behaviour is too simple, they just estimate feasibility and not the likelihood of attacks, or they do estimate likelihood but on explicitly provided attacks only. We propose a model that can detect and quantify...

MOTIVATION Chromatin immunoprecipitation (ChIP) is a powerful experimental approach to identify in vivo binding sites of sequence-specific transcription factors (TFs). These experiments are designed to specifically enrich DNA fragments that are bound to the TF. Tiling arrays have become more and more popular for the identification of these DNA fragments. However, many studies showed that only a...

background: little is known about the influence of habitual participation in physical exercise and diet on upper-extremity physical function in older adults. to assess the relationship of general physical exercise and diet to upper-extremity physical function and pain intensity in older adults.   methods: a cohort of 111 patients 50 or older completed a sociodemographic survey, the rapid assess...
