Holmium-doped fiber amplifier for pumping a ZnGeP2optical parametric oscillator
(2021-03-03)
We present a holmium-doped all-fiber master oscillator power amplifier (MOPA) system operating at 2108 nm targeting optical frequency conversion applications. The MOPA delivers pulses of 0.52 mJ energy at 10 kHz repetition ...
Augmenting Radar Doppler Resolution with Neural Networks
(2021-12-08)
In order to generate high-resolution Doppler profiles a radar needs to emit a large number of pulses within a coherent processing interval (CPI). For a radar operating in demanding scenarios it can be difficult to sustain ...
Exploring Dynamic Inoperability Input-Output Modelling of Cascading Consequences in a Total Defence Perspective
(2021-09-20)
The purpose of this work was to explore how the so-called inoperability input-output model (IIM) can be used as a tool for investigating scenarios and resilience aspects in a Total Defence perspective. The results show ...
Models for predicting impact sensitivity of energetic materials based on the trigger linkage hypothesis and Arrhenius kinetics
(2020)
In order to predict the impact sensitivity of high explosives, we designed and evaluated several models based on the trigger linkage hypothesis and the Arrhenius equation. To this effect, we calculated the heat of detonation, ...
Destined for deadlock? Russia, Ukraine, and the unfulfilled Minsk agreements
(2020-01-27)
Bringing peace, security, and stability to the war-torn region of Donbas has proven to be a challenging — some would say near-impossible — task. The "Minsk II" agreement, signed in February 2015, was supposed to put an end ...
Konsekvenser av NATOs BNP-mål for Forsvarets langtidsplanlegging
(2020-03-30)
NATO-medlemslandene har blitt enige om å øke sine forsvarsbudsjetter mot to prosent av BNP innen 2024.
I dette notatet tar vi for oss hvilken usikkerhet et slikt prosentmål kan innebære for Forsvaret, og hvilke
utfordringer ...
Effekter av støyforurensning på havmiljø - kunnskapsstatus og forvaltningsrådgiving
(2020-04-01)
Menneskeskapt støy i havet kan defineres som en type forurensning når den kommer i tillegg til
den naturlige bakgrunnsstøyen. Mer menneskelig aktivitet har ført til en økning i støynivå i havet
de siste 30–40 årene. ...
Sauebeiting på områder med vegetasjon som er tilsatt jord med og uten tungmetaller – en eksperimentell studie
(2020-02-18)
Dyr som beiter i utmark i Norge vil kunne komme i kontakt med aktive og nedlagte skytebaner.
Kontakten kan utgjøre en risiko for dyra ved at tungmetaller som bly (Pb) og kobber (Cu) som
har akkumulert i jorda tas opp ...
Cloud-based decision support system for planning military operations
(2020-02-21)
When planning a military operation, it is important to explore possibilities and understand consequences
of the plan. To this end, wargaming can be used for assessing possible courses of
action (COA) for own and enemy ...
Optimisation of performance-based continuation training – Study report for ANNC Collaborative Project between NLD and NOR – NLR Report TR-2021-172
(2021-09-10)
This report documents the findings of a collaborative project within the Anglo-Netherlands-Norwegian collaboration (ANNC) between the Royal Netherlands Aerospace Centre (NLR) and the Norwegian Defence Research Establishment ...
