1. 1. Modeling the penetration of fragmented shaped charge jets

   University essay from Uppsala universitet/Materialfysik

   Author : Alexander Palfelt; [2023]
   Keywords : Shaped charge; Analytical penetration model; Visualization; Riktad sprängverkan; RSV; Analytisk penetrationsmodell; Visualisering;

   Abstract : The penetration power of a shaped charge is an important characteristic in determining its capability. A model has previously been developed by FOI to analytically predict the penetration of a shaped charge jet striking a target at varying stand-off distances. READ MORE

3. 2. Battery field data-oriented investigation of cell capacity spread and its impacts

   University essay from

   Author : Muhammad Bilal; [2022]
   Keywords : Cell Capacity; Electric Vehicles; Algorithm; Current Profile; Voltage;

   Abstract : In this research thesis, a new data-centric approach is used to determine the individual cell capacities in Li-ion batteries used in electric vehicles (EVs). This approach could also be extended to batteries for static energy storage applications. READ MORE

4. 3. Thermoelectric measurements on InAs nanowires with a ratchet-barrier

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Author : Hanna Lundström; [2022]
   Keywords : Physics and Astronomy;

   Abstract : Efficient extraction of thermal energy from electrons at the micro- and nanoscale is a long-standing scientific goal that could enable novel types of heat engines, heat management, and solar cell applications. Semiconductor nanowires are a promising system for investigating such devices for several reasons, such as their thermoelectric properties, and the potential to be grown in heterostructures with high flexibility.

5. 4. The impact of ion drift in a Transcutaneous Electrical Stimulation model

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Oscar Tuvesson; Erik Blåe; [2022]
   Keywords : TES; neuron activation; ion drift; conductivity; COMSOL; FEM; Technology and Engineering;

   Abstract : A major area of research in neuroscience is the effect of stimulating nerves into activation from extrinsic stimuli. This is commonly done with electric currents and external skin-contact electrodes. READ MORE

6. 5. Jet fragmentation in shaped charges

   University essay from KTH/Matematik (Avd.)

   Author : Joakim Ericson; [2022]
   Keywords : Shaped charges; numerical simulation; jet fragmentation; Riktad sprängverkan; numerisk simulering; strål-fragmentering;

   Abstract : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. READ MORE
