A 11‐day compressed overload and taper induces larger physiological improvements than a normal taper in elite cyclists
(2019-08-28)Endurance athletes usually achieve performance peaking with 2‐4 weeks of overload training followed by 1‐3 weeks of tapering. With a tight competition schedule, this may not be appropriate. Thus, the aim of this study was ... -
A 2.5-D Integrated Data Logger for Measuring Extreme Accelerations
(2017)A very compact and rugged 2.5-D integrated data logger has been built and tested. The data logger is capable of measuring accelerations exceeding 70 000 g. Microcontroller and flash memory as bare dies have been mounted ... -
24 Hour Test of a Fuel Cell System for an Autonomous Underwater Vehicle
(2016)The Norwegian Defence Research Establishment (FFI) has a long experience with power sources for autonomous underwater vehicles (AUVs). FFI has designed and built a power supply system based on a water-cooled and air-supplied ... -
250-MHz synchronously pumped optical parametric oscillator at 2.25–2.6 μm and 4.1–4.9 μm
(2012)A compact and versatile femtosecond mid-IR source is presented, based on an optical parametric oscillator (OPO) synchronously pumped by a commercial 250-MHz Er:fiber laser. The mid-IR spectrum can be tuned in the range ... -
3-D Printed Monolithic GRIN Dielectric-Loaded Double-Ridged Horn Antennas
(2019-09-06)Monolithic integration of 3-D printed gradient index (GRIN) dielectric loading with a double-ridged rectangular horn standard gain horn (SGH) and its impact on antenna performance are demonstrated. Results show that the ... -
A 3D Reactive Collision Avoidance Algorithm for Nonholonomic Vehicles
(2018)This paper presents a 3D reactive collision avoidance algorithm for vehicles with nonholonomic constraints. The algorithm steers the heading and pitch angle of the vehicle in order to maintain a constant avoidance angle ... -
A 3D reactive collision avoidance algorithm for underactuated underwater vehicles
(2020-02-28)Avoiding collisions is an essential goal of the control system of autonomous vehicles. This paper presents a reactive algorithm for avoiding obstacles in a three‐dimensional space, and shows how the algorithm can be applied ... -
A 3D Reactive Collision Avoidance Algorithm for Underactuated Vehicles
(2018)This paper presents a 3D reactive collision avoidance algorithm for vehicles with underactuated dynamics. The underactuated states cannot be directly controlled, but are controlled indirectly by steering the direction of ... -
3D Rendering of Shipwrecks from Synthetic Aperture Sonar
(2021-10-25)Synthetic aperture sonar (SAS) bathymetric mapping provides centimeter-scale horizontal resolution of the seafloor. Typically, SAS data has been visualized as 2D images or gridded 2.5D surfaces, but it can also be plotted ... -
'Abdallah 'Azzam and Palestine
(2013)ʿAbdallāh ʿAzzām (1941–1989) helped make jihadism more transnational by spearheading the effort to bring Muslim foreign fighters to Afghanistan in the 1980s. But why would a West Bank native devote himself to a war in ... -
Abstraction-decomposition space for critical infrastructure systems: A framework for infrastructure planning and resilience policies
(2022-04-20)The objective of this work has been to propose a framework that will aid governments with the development of more coherent and effective infrastructure planning and resilience policies through a system-of-systems approach ... -
Abstracts from The Cold Weather Operations Conference 2021
(2022-03-11)A common effort for both military and civil healthcare is to achieve knowledge-based health care in cold weather injuries and fatal accidents in harsh arctic environment. The Cold Weather Operations Conference in November ... -
Accumulation of copper and lead in ruminants grazing on a contaminated shooting range in Nordland County, Norway
(2024)Shooting ranges contain copper (Cu) and lead (Pb) contamination, which can be a risk for grazing ruminants. This study examines the accumulation of lead and copper in blood of lambs and calves, as well as in the liver of ... -
Accumulation of lead (Pb) in brown trout (Salmo trutta) from a lake downstream a former shooting range
(2017)An environmental survey was performed in Lake Kyrtjønn, a small lake within an abandoned shooting range in the south of Norway. In Lake Kyrtjønn the total water concentrations of Pb (14 µg/L), Cu (6.1 µg/L) and Sb (1.3 ... -
Acoustic seabed classification using QTC IMPACT on single-beam echo sounder data from the Norwegian Channel, northern North Sea
(2013)Sediment mapping is important for understanding the physical processes, the impact of human activity, and the conditions for marine life on the seabed. For this purpose, the seabed classification tool QTC IMPACT analyses ... -
Active spacecraft potential control investigation
(2014)In tenuous plasma the floating potential of sunlit spacecraft reaches tens of volts, positive. The corresponding field disturbs measurements of the ambient plasma by electron and ion sensors and can reduce micro-channel ... -
Adapting OLSR for WSNs (iOLSR) Using Locally Increasing Intervals
(2012)Proactive link state routing protocols, popular within the Mobile Ad hoc NETwork framework, have not been as successful in wireless sensor networks. This is mainly due to the extensive energy usage by control traffic ... -
Adaptive phase estimation filter in long range synthetic aperture sonar interferometry
(2023-05-15)Synthetic aperture sonar (SAS) interferometry is a technique for very high resolution imaging and mapping of the seabed. In SAS interferometry, the seabed depth estimation performance is a function of the system, the ... -
Adaptive suppression of smart jamming with FDA permutation
(2022-05-03)By adding a frequency increment to the carrier frequency of the pulses transmitted from an antenna array, it becomes possible to make the beam dependent on both frequency and range. This is called a frequency diverse ... -
