Condensation heat transfer of CO2 on Cu based hierarchical and nanostructured surfaces
(Peer reviewed; Journal article, 2021)Phase-change processes such as condensation are efficient means of heat transfer. However, condensation is also an energy-intensive process and extensive research is conducted to increase the heat transfer efficiency. ... -
Condensational and Collisional Growth of Cloud Droplets in a Turbulent Environment
(Peer reviewed; Journal article, 2020)We investigate the effect of turbulence on the combined condensational and collisional growth of cloud droplets by means of high-resolution direct numerical simulations of turbulence and a superparticle approximation for ... -
Condições de uma transição para o paradigma do questionamento do mundo

Condition Assessment of Hydrogenerator Stator Bar Insulation Using Partial Discharge Measurements
(Chapter, 2018)This paper presents results from laboratory measurements of partial discharge (PD) activity in 50 cm long samples cut from the mainwall section of old hydrogenerator stator bars. All stator bars were manufactured in 1976 ... -
A Condition Monitoring Method for Solder Layer Degradation of Liquid-Cooled Power Semiconductors
(Chapter, 2023)This paper presents a new method for condition monitoring of solder layer degradation of liquid-cooled power semiconductors. Solder layer degradation is detected by an increased thermal impedance, which has the effect that ... -
Condition Monitoring of High Voltage Circuit Breakers: Past to Future
(Journal article; Peer reviewed, 2020)High voltage circuit breakers (HVCBs) play a critical role on providing the desired reliability, and resiliency in power systems. In order to extend their lifetime and predict the failures, various maintenance policies ... -
Condition Monitoring of Ship Propulsion Systems: State-of-the-Art, Development Trend and Role of Digital Twin
(Chapter, 2021)This paper describes the current implementations and development trends of condition monitoring as it pertains to ship propulsion systems. In terms of total incidents in the shipping industry in the last five years, failures ... -
Condition monitoring of spar‐type floating wind turbine drivetrain using statistical fault diagnosis
(Journal article, 2018)Operation and maintenance costs are significant for large‐scale wind turbines and particularly so for offshore. A well‐organized operation and maintenance strategy is vital to ensure the reliability, availability, and ... -
Condition Monitoring of Wound Field Synchronous Generator under Inter-turn Short Circuit Fault utilizing Vibration Signal
(Chapter, 2020)In this paper, a novel frequency index for Inter Turn Short Circuit (ITSC) fault diagnosis of the Wound Field Synchronous Generator (WFSG) is presented by utilizing the air gap flux density and the total force density. The ... -
Condition-based Maintenance for Systems with Dependencies: Related Concepts, Challenges and Opportunities
(Chapter, 2021)Many critical systems with dependencies do not collapse immediately due to single-point failures but are more vulnerable to the cascading effects of these failures. Condition-based maintenance (CBM) has been found useful ... -
Conditional estimates for the logarithmic derivative of Dirichlet L-functions
(Peer reviewed; Journal article, 2023) -
Conditional fiducial models
(Journal article; Peer reviewed, 2017)The fiducial is not unique in general, but we prove that in a restricted class of models it is uniquely determined by the sampling distribution of the data. It depends in particular not on the choice of a data generating ... -
Conditional Goodness-of-Fit Tests for Discrete Distributions
(Journal article; Peer reviewed, 2022)In this paper, we address the problem of testing goodness-of-fit for discrete distributions, where we focus on the geometric distribution. We define new likelihood-based goodness-of-fit tests using the beta-geometric ... -
A conditional model of local income shock and civil conflict
(Journal article; Peer reviewed, 2021)Common political economy models point to rationalist motives for engaging in conflict but say little about how income shocks translate into collective violence in some cases but not in others. Grievance models, in contrast, ... -
Conditional Monte Carlo revisited
(Peer reviewed; Journal article, 2021)Conditional Monte Carlo refers to sampling from the conditional distribution of a random vector X given the value T ( X ) = t for a function T ( X ) . Classical conditional Monte Carlo methods were designed for estimating ... -
Conditional Pulse Density Modulation for Inductive Power Transfer Systems
(Peer reviewed; Journal article, 2023)This letter proposes a conditional pulse density modulation (PDM) method for Inductive Power Transfer (IPT) systems, which can automatically adapt the generated output patterns to effectively suppress current/power ripples. ... -
Conditional Standard Error of Measurement: Classical Test Theory, Generalizability Theory and Many-Facet Rasch Measurement with Applications to Writing Assessment
(Peer reviewed; Journal article, 2021)Writing assessments often consist of students responding to multiple prompts, which are judged by more than one rater. To establish the reliability of these assessments, there exist different methods to disentangle variation ... -
Conditions for just offshore wind energy: Addressing the societal challenges of the North Sea wind industry
