Design and implementation of a low-cost FMCW imaging radar by Tchekashkin, Ivan

“…This is achieved by generating two identical L-FMCW waveforms that are offset by a chosen time period. This enables a shift of the spectrum by the frequency, which corresponds to the time offset. …”

System design of the MeerKAT L - band 3D radar for monitoring near earth objects by Agaba, Doreen

“…From this feasibility study, the MeerKAT 3D distributed radar will be able to detect debris of diameter less than 10 cm at altitudes between 700 km to 900 km, and PHAs, with a range resolution of 15 m, a minimum SNR of 14 dB for 152 pulses for a coherent integration time of 2.02 ms. The target range (derived from the two way delay), velocity (from Doppler frequency) and direction will be measured within an accuracy of: 2.116 m, 15.519 m/s, 0.083° (single antenna), respectively. …”

Noise reduction during diffusion tensor imaging of infants by Jordaan, Johannes Petrus

“…Lastly, the effectiveness of introducing pink noise from an external source to mask the abrupt changes in scanner noise, was also investigated. The altered k-space trajectories due to the modifications made to the EPI readout gradient waveforms were corrected through a custom one-dimensional regridding procedure applied along the frequency encoding axis in k-space. …”

The role of waterbirds in the dispersal of aquatic organisms in southern Africa by Reynolds, Chevonne

“…Furthermore, there is still little knowledge of the spatial patterns of propagule dispersal and the mechanisms that cause these patterns to vary in space and over time. This thesis aims to addresses several of these knowledge gaps in waterbird-mediated dispersal and presents the first detailed study of propagule dispersal by waterbirds anywhere in Africa. …”

Quantifying spatial and temporal scales of phytoplankton variability in the Sub-Antarctic Ocean using a high-resolution glider dataset by Little, Hazel Jean

“…Phytoplankton in the Sub-Antarctic Southern Ocean have a distinct seasonal cycle, which is highly variable in both space and time. The seasonal and spatial distribution of chlorophyll can be attributed to the complex nature of the physical and biogeochemical factors controlling phytoplankton production. …”

When will the lokshin MyCiTi bus arrive for first thursdays in the city? Exploring township-dwelling people s perspectives on mobility for discretionary activity participation af... by Fischer, Ayanda

“…The findings of the study reveal that trip-making for discretionary activity participation among a vulnerable group is limited not necessarily by choice, but by income constraints, spatial disadvantage, a sense of not belonging to historically Whites-only areas of Cape Town and the aggravation of insufficient frequency of preferred public transportation modes during the evening time. …”

The development of an exercise intervention framework as a modality of treatment for individuals with obstructive sleep apnea, in the South African public healthcare setting by Jaffer, Zakirah

“…Conclusion: Taking into account the observations 7 from evidence-based reviews in Chapter 1 and the results from Chapter 2, the proposed framework should include an exercise intervention that considers a moderate frequency of three to five times/week, a medium and building up to a higher intensity of 40-80% HRR, shorter sessions of 25-40 minutes per session but building up to 60 minutes where possible, and inclusion of aerobic and resistance exercises with a focus on walking as well as lower body activities. …”
