How far a user can rely on his navigation system is a central question for safety of life applications like air navigation especially in approach phases. For Oceanic, En route or Non Precision Approach phases, the integrity requirements as defined by the ICAO (International Civil Aviation Organization) should be fulfilled by the future Galileo Safety of Life Service. This paper presents the per...

Stanford’s Integrity Beacon Landing System uses ground-based pseudo-satellite transmitters known as Integrity Beacons to resolve carrier phase ambiguities on final approach, giving IBLS both high integrity and centimeter-level accuracy. This paper discusses two improved Integrity Beacon designs and the results of flight tests with these new beacons. The original Integrity Beacons were not synch...

The purpose of this explorative study was to investigate whether diffusion tensor imaging (DTI) and diffusion kurtosis imaging (DKI) parameter changes are reliable measures of white matter integrity changes in Alzheimer's disease (AD) patients using a whole brain voxel-based analysis (VBA). Therefore, age- and gender-matched patients with mild cognitive impairment (MCI) due to AD (n = 18), deme...

Ultra Thin Body (UTB) SOI MOSFETs are increasingly competitive for nanometre scale VLSI applications due to superior electrostatic integrity compared to conventional MOSFETs. The possibility to use undoped channels in such devices also dramatically reduces the random dopant induced parameter fluctuations. To fully realise performance benefits of UTB SOI based circuits a statistical circuit simu...

A confidence interval is an interval (i.e., a range of values) estimate of a parameter of a population (e.g., a mean) calculated from a sample drawn from the population. A confidence interval has an associated confidence level, which is frequency with which a calculated confidence interval is expected to contain the population parameter. Confidence intervals are of interest in modeling and simu...

semen quality and its relationship to fertility are major concern in animal production. the aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through artificial insemination(ai). semen samples were collected from four buffalo bulls. semen volume and sperm concentration appeared to be significantly different (p0...

this study was conducted to determine chromatin integrity and dna damage by dna electrophoresis and comet assays of buffalo fresh and frozen semen. semen samples were collected from four buffalo bulls and evaluated after freezing for semen motility, viability, sperm abnormalities, chromatin integrity and dna damage. a significant variation was found in semen parameters after thawing. highly sig...

The Resource Space Model (RSM) is a semantic data model based on orthogonal classification semantics for effectively managing various resources in interconnection environment. In parallel with the integrity theories of relational and XML-based data models, this keynote presents the integrity theory for the RSM, including the entity integrity constraints based on the key system of the RSM, the m...

This paper’s approach to semantic integrity management is that in order to maintain an integrity constraint, some variables of the constraint may be operated on while others may not This defines integrity dependencies between vsiables. Various examples of integrity dependencies and their meanings are discussed. In addition to corresponding to real world practice, integrity dependencies can be u...

Fault injection attacks are a real-world threat to cryptosystems, in particular asymmetric cryptography. In this paper, we focus on countermeasures which guarantee the integrity of the computation result, hence covering most existing and future faults attacks. Namely, we study the modular extension protection scheme in previously existing and newly contributed variants of the countermeasure on ...
