1. 1. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Jessica McKenna; [2023]
   Keywords : Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

   Abstract : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

3. 2. Effects of Prolonged Electricity Supply Disruptions on Critical Entities

   University essay from Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Author : André Hansson; [2023]
   Keywords : vital societal function; VSF; critical entity; CE; vital societal entity; VSE; critical infrastructure; CI; critical flow; prolonged outage; electricity supply disruption; preparedness; total defence; civil defence; civil preparedness; crisis preparedness; grey zone; critical entities resilience; CER; hybrid warfare; energy security; societal resilience; cascading effect; dependencies; interdependencies; long-term disruption; power outage; power disruption; consequences; outage; samhällsviktig verksamhet; kritisk infrastruktur; totalförsvar; beredskap; Technology and Engineering;

   Abstract : This study investigates Swedish critical entities (CEs) ability to maintain function during up to three months of electricity supply disruptions. It also examines possible improvement measures, and how contextual cases (grey zone, heightened state of alert, war) influence CEs’ ability to maintain function during electricity supply disruptions.

4. 3. Klimatsäkring av riksintressanta hamnar : en fallstudie om Helsingborgs hamn och dess framtid

   University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

   Author : Alexander Larsson; [2023]
   Keywords : klimatförändringar; klimatanpassningar; resiliens; hamn; Helsingborg;

   Abstract : Sveriges näst största containerhamn, Helsingborgs hamn, hotas av höjda havsnivåer vilket kan leda till att verksamheten med containrar inte kan bedrivas redan år 2035. Detta innebär en stor risk för störningar i försörjningskedjor och kan få kaskadeffekter på samhället. READ MORE

5. 4. Analysis of a high step-up gain DC-DC converter for fuel cell and battery application

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Kaj Törngren Sato; [2023]
   Keywords : Fuel cell; High step-up DC-DC converter; Boost converter; Coupled inductors; Coupling factor; CCM; DCM; Duty cycle;

   Abstract : In sustainable energy systems those using fuel cells, high step-up gain converters are widely used to increase the output voltage to levels that can be used by other converters, such as inverters for grid connection or powering other AC loads. In order to obtain a higher voltage gain, in comparison to a traditional boost converter, often different topologies techniques are involved. READ MORE

6. 5. Pros and Cons of Using Large Concrete Blocks in an Office Building Structure : Comfort, Stability, Sustainability

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

   Author : Shwan Baban; Asliyalfani Abolfazl; [2023]
   Keywords : Concrete blocks; C3C blocks; FE models; life cycle analysis; mechanical connections; CO2 emissions.;

   Abstract : In 2019, the cement industry used 280 million tons of oil equivalent, contributing to 7% of totalindustrial energy consumption. This resulted in 2.4 billion tons of CO2 emissions, constituting26% of the industrial sector’s CO2 output and 7% of global energy-related emissions. READ MORE
