Uniform semiglobal exponential stability of integral line-of-sight guidance laws
(2015)This paper proves that an integral line-of-sight guidance law for path following control of underactuated marine vessels provides uniform semiglobal exponential stability. The stability result is stronger than what has ... -
A Multiscale Wavelet-Based Test for Isotropy of Random Fields on a Regular Lattice
(2015)A test for isotropy of images modeled as stationary or intrinsically stationary random fields on a lattice is developed. The test is based on the wavelet theory, and can operate on the horizontal and vertical scale of ... -
Harmonic Synthetic Aperture Radar Processing
(2015)We review the basic concept of frequency-modulated continuous wave (FMCW) and describe how such a radar system can be used in a harmonic radar concept. It is argued that synthetic aperture radar (SAR) for FMCW harmonic ... -
In-Body to On-Body Ultrawideband Propagation Model Derived from Measurements in Living Animals
(2015)Ultra wideband (UWB) radio technology for wireless implants has gained significant attention. UWB enables the fabrication of faster and smaller transceivers with ultra low power consumption, which may be integrated into ... -
A survey of dioxin-like contaminants in fish from recreational fishing
(2015)The dioxin and dioxin-like compounds are regarded as one of the most toxic group of environmental contaminants. Food for the commercial market is regularly monitored for their dioxin levels and the concentration allowed ... -
Robust Identification of Concealed Dangerous Substances by Spectral Correlation of Terahertz Transmission Images
(2015)Terahertz (THz) images containing spectral information in each pixel are recorded in transmission mode using a fiber-coupled time-domain spectroscopy system. The images are acquired by mounting a sample holder on an x-y ... -
Disruptive camouflage tricks the human eye - a study of detection times of two near-similar targets in natural backgrounds
(2015)Our understanding of camouflage, in military as well as in evolutionary perspectives, has been developing over the last 100 years. In that period of time several underlying principles have emerged. It has turned out in the ... -
A hybrid recorded-synthetic sonar data set for validation of ASW classification algorithms
(2015)Modern anti-submarine warfare sonars are often designed with narrow beamwidths and wide frequency bandwidths in order to maximize spatial resolution and sonar performance. A known issue for high-resolution sonars in littoral ... -
Are team personality and climate related to satisfaction and software quality? Aggregating results from a twice replicated experiment
(2015)Context Research into software engineering teams focuses on human and social team factors. Social psychology deals with the study of team formation and has found that personality factors and group processes such as team ... -
A Radon-Transform-Based Image Noise Filter - With Applications to Multibeam Bathymetry
(2015)This paper describes a linear-image-transform-based algorithm for reducing stripe noise, track line artifacts, and motion-induced errors in remote sensing data. Developed for multibeam bathymetry (MB), the method has also ... -
Supralethal poisoning by any of the classical nerve agents is effectively counteracted by procyclidine regimens in rats
(2015)A treatment regimen consisting of HI-6, levetiracetam, and procyclidine (termed the triple regimen) has previously been shown to work as a universal therapy against soman poisoning in rats, since it has capacities to ... -
Identification of airborne bacteria by 16S rDNA sequencing, MALDI-TOF MS and the MIDI microbial identification system
(2015)The aim of this study was to collect and identify airborne bacteria in Norway, Sweden and Finland and to compare three different technologies for identifying collected airborne bacterial isolates: the “gold standard” method ... -
Predator sound playbacks reveal strong avoidance responses in a fight strategist baleen whale
(2015)Anti-predator strategies are often defined as ‘flight’ or ‘fight’, based upon prey anatomical adaptations for size, morphology and weapons, as well as observed behaviours in the presence of predators. The humpback whale ... -
Robust identification of concealed dangerous substances using THz imaging spectroscopy
(2015)False alarm rates must be kept sufficiently low if a method to detect and identify objects or substances is to be implemented in real life applications. This is also true when trying to detect and identify dangerous ... -
Measurements and modeling of effects of out-of-plane reverberation on the power delay profile for underwater acoustic channels
(2015)Long reverberation tails are often observed in shallow-water acoustic channel impulse responses (CIRs). Examples from three significantly different environments along the Norwegian coast are presented. It is shown that 2-D ... -
Automatic Security Classification by Machine Learning for Cross-Domain Information Exchange
(2015)Cross-domain information exchange is necessary to obtain information superiority in the military domain, and should be based on assigning appropriate security labels to the information objects. Most of the data found in a ... -
Search by photo methodology for signature properties assessment by human observers
(2015)Reliable, low-cost and simple methods for assessment of signature properties for military purposes are very important. In this paper we present such an approach that uses human observers in a search by photo assessment of ... -
Resilient internetwork routing over heterogeneous mobile military networks
(2015)Mobile networks in the military tactical domain, include a range of radio networks with very diverse characteristics and which may be employed differently from operation to operation. When interconnecting networks with ... -
Discriminating between camouflaged targets by their time of detection by ahuman based observer assessment method
(2015)Detection of a camouflaged object in natural sceneries requires the target to be distinguishable from its local background. The development of any new camouflage pattern therefore has to rely on a well-founded test methodology ... -
Wideband Propagation Characteristics at 312 MHz in Eastern Norway and Impact on Waveform Requirements
(2015)A wideband Pseudo-Noise channel sounder built by CRC in Canada has been used to measure the wideband channel characteristics in three different types of terrain in Eastern Norway. The channel characteristics at 312 MHz are ...
