Direct Simulation of Surge Tank Stability
(Master thesis, 2018)This thesis deals with the issue of surge tank stability in hydropower plants, investigating methods used to design the surge tank area required to guarantee stability. Currently, Thoma equation (1910) is widely accepted ... -
Direct Synthesis of Dimethyl Ether in Microstructured Reactors
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:81, Doctoral thesis, 2011) -
Direct Synthesis of Dimethyl Ether in Microstructured Reactors: The Interactions Between Methanol Synthesis and Methanol Dehydration
(Doctoral thesis at NTNU;2016:179, Doctoral thesis, 2016)The growing concerns about the climate change, energy security and the diminishing oil reserves, stimulate the search for alternative energy sources and non-petroleum-based fuels. Natural gas in the short-term, and biomass ... -
The direct topographical correction in gravimetric geoid determination by the Stokes-Helmert method
(Peer reviewed; Journal article, 2000)The direct topographical correction is composed of both local effects and long-wavelength contributions. This implies that the classical integral formula for determining the direct effect may have some numerical problems ... -
Direct training of robots using a positional deviation sensor
(Doktor ingeniøravhandling;1988:33, Doctoral thesis, 1988)A device and system for physically guiding a manipulator through its task is described. The device consists of inductive, contact-free positional deviation sensors, enabling the rcbot to track a motion marker. Factors ... -
Direct Visual Odometry on a GPU
(Master thesis, 2019)Denne masteroppgaven dekker implementasjonen av DVO (Direct Visual Odometry) algoritmen på en GPGPU (General-purpose Graphical Processing Unit). DVO er en direkte visuell odometri algoritme som er i stand til å estimere ... -
Direct Yaw Moment, Traction and Power Limit Control of a Four Wheel Independent Drive Electric (4WID-EV) Formula Student Race Car
(Master thesis, 2016)This master's thesis describes the development, implementation and testing of a suite of control systems consisting of torque vectoring, traction control and power limit control for a Formula style race car using four ... -
Directed Energy Deposition versus Wrought Ti-6Al-4V: A Comparison of Microstructure, Fatigue Behavior, and Notch Sensitivity
(Journal article; Peer reviewed, 2019)Laser Engineered Net Shaping (LENS), a Direct Energy Deposition (DED) additive manufacturing process is a 3D manufacturing process generally used to produce fully dense parts or to repair/add additional material to an ... -
Directed Lithiation of Protected 4-Chloropyrrolopyrimidine: Addition to Aldehydes and Ketones Aided by Bis(2-dimethylaminoethyl)ether
(Peer reviewed; Journal article, 2023)Pyrrolopyrimidines are important scaffolds for the preparation of bioactive molecules. Therefore, developing efficient and flexible ways for selective functionalization of the pyrrolopyrimidine skeleton is of interest. We ... -
Direction Following Control of Planar Snake Robots Using Virtual Holonomic Constraints
(Journal article; Peer reviewed, 2015)This paper investigates the problem of direction following for planar snake robots. The control objective is to regulate the linear velocity vector of the snake robot to a constant reference while guaranteeing boundedness ... -
The Direction of Updatable Encryption Does Not Matter Much
(Peer reviewed; Journal article, 2020)Updatable encryption schemes allow for key rotation on ciphertexts. A client outsourcing storage of encrypted data to a cloud server can change its encryption key. The cloud server can update the stored ciphertexts to the ... -
Direction- and Angle-Assisted Buttonhole Cannulation of Arteriovenous Fistula in Hemodialysis Patients: A Multicenter Randomized Controlled Trial
(Peer reviewed; Journal article, 2022)Rationale & objective: Arteriovenous fistula cannulation with the buttonhole technique is often preferred by patients but has been associated with an increased infection risk. Guidelines disagree on whether it should be ... -
Directional Decomposition of Images: Implementation Issues Including GPU Techniques
(Master thesis, 2008)Directional decomposition of an image consists of separating it into several components, each containing directional information in some specific directions. It has many applications in digital image processing, such as ... -
Directional Drilling - Advanced Trajectory Modelling
