Tian, H.Y. (author), Cai, H.M. (author), Xu, X. (author), Lai, J.H. (author)Removing noise effectively without destroying important fine structure is a challenging problem in image processing. Among many techniques, diffusion method is shown to be attractive due to its rigorous mathematical background and efficiency. In this paper we propose a well-balanced diffusion method by redefining the diffusion and regularization...conference paper 2011

(author)In this paper, we propose an approach to autonomously control a quadrotor micro aerial vehicle (MAV). With take-off weight of 50 g and 8-min flight endurance, the MAV platform codenamed KayLion developed by the National University of Singapore (NUS) is able to perform autonomous flight with pre-planned path tracking. The vision-based...conference paper 2014

Ting, F. (author), Reimnitz, J. (author), Auch, M. (author), Lai, W. (author)The instantaneous turbulent velocity fields under plunging regular waves were measured in a wave flume using the volumetric three-component velocimetry (V3V) technique. The measurement volume was approximately 140 mm long, 140 mm wide, and 85 mm high extending from the bottom of a plane slope to the wave trough level. The aerated water was...conference paper 2013

(author), Hendriks, B.H.W. (author), de With, Peter H.N. (author)Peripheral Artery Diseases (PAD) are caused by the occlusions of arteries in the peripheral locations of the circulatory system. The severity of PAD is usually assessed using the Ankle Brachial Index (ABI) and the Ultrasound Doppler. Non-contact Photoplethysmography (PPG) imaging is a recent emerging technology capable of monitoring skin...conference paper 2021

(author), De With, Peter H.N. (author)Neurosurgical training is performed on human cadavers and simulation models, such as VR platforms, which have several drawbacks. Head phantoms could solve most of the issues related to these trainings. The aim of this study was to design a realistic and CT-compatible head phantom, with a specific focus on endo-nasal skull-base surgery and...conference paper 2021

(author)In neurosurgery, technical solutions for visualizing the border between healthy brain and tumor tissue is of great value, since they enable the surgeon to achieve gross total resection while minimizing the risk of damage to eloquent areas. By using real-time non-ionizing imaging techniques, such as hyperspectral imaging (HSI), the spectral...conference paper 2020

(author), Momi, E. De (author)Navigation inside luminal organs is an arduous task that requires non-intuitive coordination between the movement of the operator's hand and the information obtained from the endoscopic video. The development of tools to automate certain tasks could alleviate the physical and mental load of doctors during interventions allowing them to focus on...conference paper 2022

However, we believe that despite its potential benefits on society, there could be more activity in this area. The aim of this workshop is create a forum for more interdisciplinary dialogue on this topic to enable the acceleration of...conference paper 2018

(author)The method of characteristics, or fractional-flow theory, is extremely useful in understanding complex Enhanced Oil Recovery (EOR) processes and in calibrating simulators. One limitation has been its restriction to Newtonian rheology except in rectilinear flow. Its inability to deal with non-Newtonian rheology in polymer and foam EOR has been a...journal article 2011

(author)Background Crossing over assures the correct segregation of the homologous chromosomes to both poles of the dividing meiocyte. This exchange of DNA creates new allelic combinations thus increasing the genetic variation present in offspring. Crossovers are not uniformly distributed along chromosomes; rather there are preferred locations where...journal article 2015
