1. 1. Why should 3D Gait Analysis be included in the Walking Pattern Assessment of individuals with Spinal Cord Injury? : Biomechanical analysis of gait and gait patterns in individuals with spinal cord injury

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Chiara Pollicini; [2022]
   Keywords : Spinal cord injury; 3D gait analysis; gait features; GDI; GPS; Clinical assessments; ASIA scale;

   Abstract : Background: The yearly incidence of people with Spinal Cord Injury (SCI) is between250,000 and 500,000, according to the World Health Organization (WHO). The injury often reduces the ability to walk. Various consequences affect the nervous system and, thus, the entire body. READ MORE

4. 3. Statistical Analysis of Equalization Enhanced Phase Noise in Coherent Fiber Optical Communications

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Thomas Gaudy; [2016]
   Keywords : ;

   Abstract : Coherent optical communications increase the receiver sensitivity and the total capacity. Together with high speed digital signal processing (DSP), compensation for linear transmission impairments (chromatic dispersion, polarization mode dispersion and phase noise) can be achieved.

5. 4. Digital Pre-compensation of Chromatic Dispersion in QPSK high speed telecom systems

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Maria Sol Lidon; [2011]
   Keywords : ;

   Abstract : Chromatic dispersion (CD) is one of the most significant impairments in optical fiber communication systems. Since expensive and complex optical components are required to mitigate CD in the optical domain high-speed digital signal processing techniques are becoming an alternative to compensate electronically both non-linear and linear optical fiber degradations in the transmitter or receiver.

6. 5. The influence of the dispersionmap on optical OFDM transmissions

   University essay from Institutet för rymdfysik, Uppsalaavdelningen

   Author : Kamyar Forozesh; [2010]
   Keywords : OFDM; fiber; optic; dispersion; optical transmission;

   Abstract : Fiber-optic networks are an integral part of todays digital communication system. In these networks, distances of typically 400 km to 6000 km are linked together, and information is transfered at extremely high data rates. READ MORE
