Photogrammetry-based 3D scanning for supporting design activities and testing in early stage product development
(Peer reviewed; Journal article, 2021)In the early stages of product development and design, physical prototypes are designed and built from varying materials with the aim of providing valuable experience and decision support for the project team. In the era ... -
Photography - A New Tool in Needfinding
(Chapter, 2015)In this paper we are proposing the use of photography as a dedicated tool to capture latent needs and create anchor points for future solutions in engineering design. We are grounded in user centric design. Based on a ... -
Photography - Bridging the Gap between Needfinding and Visual Thinking
(Master thesis, 2015)Founding on the pre-master project Photography a new tool in needfinding (Wulvik et al., 2015) as starting point and based on theory from the fields of needfinding and visual thinking, an explorative experiment has ... -
Physical effects of load fluctuations in rivers
(Doctoral thesis at NTNU;2014:319, Doctoral thesis, 2014)The present dissertation describes the consequences of rapid discharge variations on gravel bed rivers. It consists of a thesis part and eight attached research papers. A novel technique to artificially reproduce the ... -
Physical hydraulic model study of a bottom charged spillway: A new concept for water level control in canals
(Master thesis, 2011)The bottom charged side spillway is a new concept of spillway in which the excess water is spilled from the bottom level which is sediment rich water and the cleanest quality of water is sent to the turbine. It is different ... -
Physical hydraulic model study of the throttle trap concept for branch flow control
(Master thesis, 2011)Sediment induced wear of hydro-turbines has been a major problem in utilizing the water resources in sediment loaded rivers around the world. The problems are more sever in Himalayan Rivers, which favor high head plants ... -
Physical model study on impacts of landslide generated wave action on embankment dams
(Master thesis, 2015)The master thesis "Physical model study on impacts of landslide generated wave action on embankment dams" has been written in collaboration with the Department of Hydraulic and Environmental Engineering at NTNU and the ... -
Physical Model Tests of Intake Design
(Master thesis, 2013)As there are no detailed guidelines on how to design culverts including sediments and debris, a laboratory model was made to find solutions to how sediments deposit in front of the culvert and how this affects the capacity. ... -
Physical Modelling of Surge Tank Throttling
(Master thesis, 2015)The scope of this master thesis is to design a surge tank throttle based on literature values, and compare the expected head loss factor with the results from a 3D numerical simulation, and a physical model test. A literature ... -
Physiological Data Acquisition for Deeper Insights into Prototyping
(Chapter, 2014)Based on the work of [1] a confirmatory study was conducted and two additional questions were investigated: How does iterating ideas affect the stress level of the participants while explaining their final design? And; ... -
Physiology and sensorial based quantification of human-object interaction - the QOSI matrix
(Chapter, 2015)This paper addresses the need to quantify human-object interactions in order to get insights into the sensorial variables influencing the actual user-experiences in interaction and human centered design. The resulting ... -
Piecewise Deterministic Markov Processes for Condition-based Maintenance Modelling: Applications to Critical Infrastructures
(Doctoral theses at NTNU;2022:377, Doctoral thesis, 2022)This thesis focuses on Piecewise deterministic Markov process (PDMP), a general class of non-diffusion stochastic models, as a framework for modelling condition-based maintenance (CBM) decision problems of critical ... -
Piezoresistive Chopped Carbon Fiber Rubber Silicone Sensors for Shedding Frequency Detection in Alternating Vortex Streets
(Chapter, 2019)In nature, fish use sensory input to feel and adapt to flow conditions. Creating solutions that mimic these capabilities need flexible and sensitive sensor solutions. In this paper we use readily available carbon fibers ... -
A Pin-on-Disk Tribometer for Friction and Lubricating Performance in mm-Scale
(Peer reviewed; Journal article, 2021)A pin-on-disk tribometer for micro-scale applications is presented in this paper. The tribometer consists of a stationary mm-scale pin and a rotating disk. Friction and lubrication film thickness are measured by a laser ... -
