Arkenbout, E.A. (author), de Winter, J.C.F. (author), Ali, Anas (author), Dankelman, J. (author), Breedveld, P. (author)Iterative prototyping is costly and time-consuming. Particularly when designing medical instruments, human factors related design choices significantly impact performance and safety. A tool is presented that allows for the evaluation of steerable instrument controls before the onset of the prototyping stage. The design tool couples gestural...journal article 2018

(author), Harchowal, Jatinder (author), Rajkumar, Chakravarthi (author), Ali, Khalid (author)Aims: Medication-related harm (MRH) is common in older adults following hospital discharge. In resource-limited health systems, interventions to reduce this risk can be targeted at high-risk patients. This study aims to determine whether (1) doctors can predict which older patients will experience MRH requiring healthcare following hospital...journal article 2018

Ali, Yasir S.A. (author), Paron, Paolo (author), Crosato, A. (author), Mohamed, Yasir A. (author)Sediment accumulation hampers optimal water resources management of reservoirs. In the Roseires Reservoir across the Blue Nile River, in Sudan, about 30% of the storage capacity has been lost by sedimentation before dam heightening (2012), despite regular sediment sluicing and flushing. At the same time, increasing soil erosion in the upper...journal article 2017

Ali, A. (author), de Winter, J.C.F. (author), Dodou, D. (author), Breedveld, P. (author)To overcome the challenges presented by complex 3-dimensional shapes and tortuous vasculature in the cardiovascular environment, we previously developed a prototype of a multi-steerable catheter having 4 DOFs controlled by two joysticks [1]. However, it remains unknown whether the added steering possibilities are beneficial in the cardiovascular...abstract 2017

Ali, Y.S.A. (author)Population growth in the Blue Nile Basin has led to fast land-use changes from forest to agricultural land, which resulted in speeding up the soil erosion processes producing highly negative impacts on the local soil fertility and agricultural productivity. The eroded sediment is transported downstream by water and sinks in the lower basin where...doctoral thesis 2014
