The stabilising effect by a novel cable cerclage configuration in long cephalomedullary nailing of subtrochanteric fractures with a posteromedial wedge
(2019-05-16)Background Clinical studies suggest that an adjunctive cerclage in intramedullary nailing of subtrochanteric fractures improves the outcome. Despite this, to what extent various cerclage configurations influences the ... -
Passive LWIR hyperspectral imaging of surfaces contaminated by CWA droplets
(2019-05-17)A passive LWIR camera based on a focal plane array detector was used to capture hyperspectral images of different scenes where low volatile chemical warfare agent (CWA) and simulant droplets were deposited on a variety of ... -
p-Adic Brownian Motion as a Limit of Discrete Time Random Walks
(2019-05-25)Abstract. The p-adic di usion equation is a pseudo di erential equation that is formally analogous to the real di usion equation. The fundamental solutions to pseudo di erential equations that generalize the p-adic di ... -
Exploring the overlapping binding sites of ifenprodil and EVT‐101 in GluN2B‐containing NMDA receptors using novel chicken embryo forebrain cultures and molecular modeling
(2019-05-30)N‐methyl‐d‐aspartate receptors (NMDAR) are widely expressed in the brain. GluN2B subunit‐containing NMDARs has recently attracted significant attention as potential pharmacological targets, with emphasis on the functional ... -
Descending Infrared Transmission Spectra of CdZnTe Substrates Due to Surface Roughness
(2019-06-11)(111)B-oriented Cd0.96Zn0.04Te substrates with rough surfaces have been found to have infrared (IR) transmission spectra which decrease rapidly in intensity as the photon energy increases. The rough surfaces were produced ... -
Characterization of (111)B and (211)B CdZnTe Substrates for HgCdTe Growth
(2019-06-13)We have studied state-of-the-art CdZnTe (211)B and (111)B substrates and compared them to each other and to substrates from an alternative vendor. The CdZnTe surface has been characterized both as-received and after growth ... -
Improved Passivation Effect Due to Controlled Smoothing of the CdTe-HgCdTe Interface Gradient by Thermal Annealing
(2019-07-11)HgCdTe films grown by liquid phase epitaxy were passivated with CdTe grown by molecular beam epitaxy. A series of annealing tests with different temperatures and durations were then carried out in order to reach a two-fold ... -
Passive Radar detection of small UAV over sea
(2019-07-22)During a trial over the Trondheim-fjord in Norway fall 2018, aDVB-T based passive radar system was used for detecting a small unmanned aerial vehicle (UAV) over sea. The measurements show a possible detection range of 1 ... -
Solving non-linear Boolean equation systems by variable elimination
(2019-08-17)In this paper we study Boolean equation systems, and how to eliminate variables from them while bounding the degree of polynomials produced. A procedure for variable elimination is introduced, and we relate the techniques ... -
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 ... -
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 ... -
Predicting False Alarm Rates for High-Resolution Antisubmarine Warfare Sonars in a Cluttering Environment Prone to False Alarm Rate Inflation
(2019-09-13)Operation of high-resolution, broadband, antisubmarine warfare sonars in littoral waters is challenging, since the presence of sea mounts, underwater ridges, and other topographic features causes increased false alarm ... -
Imaging radar for navigation and surveillance on an autonomous unmanned ground vehicle capable of detecting obstacles obscured by vegetation
(2019-09-16)The Norwegian Defence Research Establishment (FFI), has developed a multi purpose radar demonstrator for Intelligence, Surveillance and Reconnaissance (ISR) on the Off-road Light Autonomous Vehicle (OLAV) platform. The ... -
A decomposition solution approach to the troops-to-tasks assignment in military peacekeeping operations
(2019-09-20)This paper considers the Peacekeeping Troops-to-Tasks Problem (PTTP). The PTTP deals with assigning battlegroup resources to a set of tasks associated with a given peacekeeping mission. The tasks may be spread across several ... -
Single-point structure tensors in turbulent channel flows with smooth and wavy walls
(2019-10-06)A long-standing problem in turbulence modeling is that the Reynolds stress tensor alone is not necessarily sufficient to characterize the transient and nonequilibrium behaviors of turbulence under arbitrary mean deformation ... -
Automatic scene understanding and object identification in point clouds
(2019-10-10)A ladar can acquire a dense set of 3D coordinates of a scene, a so-called point cloud, in sub-second time from ranges of several kilometers. This paper presents algorithms for segmenting a point cloud into meaningful classes ... -
Comparing RLS and LMS adaptive equalizers for large hydrophone arrays in underwater acoustic communication channels
(2019-10-14)There is an expected growth in underwater acoustic data traffic. To meet the demand of high data throughput, a migration towards the very high frequency band (>100 kHz) will be necessary. The increment in frequency comes ... -
The Islamic state after the caliphate
(2019-10-14)Following the Islamic State loss of most of its territorial control and the fall of its self-declared Caliphate, many have warned that it is too early to declare that the group is defeated. The group has previously been ... -
Fragmentation of an armour piercing projectile after impact on composite covered alumina tiles
(2019-11-18)In a typical body armour system, a hard armour plate is often used in conjunction with a soft ballistic panel. The main purpose of the armour plate is to erode and fragment an impacting projectile, such as 7.62 mm armour ...
