  1. 1. Development of Methodology for Finite Element Simulation of Overhead Guard Impact Test

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Axel Hallén; Jacob Hjorth; [2022]
    Keywords : Explicit Finite Element Analysis; Forklift Overhead Guard; RADIOSS; Drop Test; Strain-Rate Sensitivity; Johnson-Cook; Plasticity; Explicit finita elementanalys; Skyddstak; Gaffeltruck; RADIOSS; Fallprov; Töjningshastighetsberoende; Johnson-Cook; Plasticitet;

    Abstract : Forklifts that are capable of lifting heavy loads and reaching high lift heights are required by stan-dards to have an overhead guard to protect the operator from falling objects. The same standardsspecify a standardized procedure for testing the strength of these overhead guards. READ MORE

  3. 2. Development Of Lung Phantoms for Detection Of Acute Respiratory Distress Syndrome

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Wassim Wahbeh; Youssef Hasan; [2022]
    Keywords : DARDS;

    Abstract : The goal of this project was to fabricate a deflated and an inflated phantom to replicate how the human lung tissues’ permittivity changes under a pathological condition for instance acute respiratory distress syndrome (ARDS). Furthermore, the lung phantom should be shaped like real human lungs. READ MORE

  4. 3. OFDM Systems Offset Estimation and Cancellation Using UKF and EKF

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Dinsefa Mustefa; Ermias Mebreku; [2011]
    Keywords : Orthogonal Frequency Devision Multiplexing; Inter carrier interference; Unscented Kalman filter; Extended Kalman filter; Frequency offset; Estimation; Compensation; OFDM; UKF; EKF; ICI; ISI;

    Abstract : Orthogonal Frequency Division Multiplexing (OFDM) is an efficient multi- carrier modulation scheme, which has been adopted for several wireless stan- dards. Systems employing this scheme at the physical layer are sensitive to frequency offsets and that causes Inter Carrier Interference (ICI) and degra- dation in overall system performance of OFDM systems.
