The effects of layer deposition angle and layer temperature on the orthotropic mechanical properties of 3D printed PLA parts
… The present work focuses on the effect of layer temperature as controlled by layer printing time and cooling fan setting on the uniaxial tensile properties of 3D printed PLA for 100% and 40% linear infill prints at various print angles. As previously found, for a given print temperature, …

Upper ocean response to storms: a resonant system
… during the fall and winter, the mixed layer temperature (MLT) of the ocean decreases, mostly in short bursts associated with storms. These events have been dubbed episodic cooling events, although it has been shown (Large et al. 1986) that the associated decrease in MLT is primarily due …

Effect of internal solitary waves on mine detection in the western Philippine Sea east of Taiwan
Upper layer temperature in the western Philippine Sea near Taiwan was sampled using a coastal monitoring buoy with fifteen themistors attached from July 28-August 7, 2005. Internal waves and internal solitons were identifed during the empirical orthogonal function analysis. Without the IW and IS, …

In-Situ Monitoring of Additive Manufacturing Using Digital Image Correlation
… due to variations in two process parameters: layer resolution and print temperature. Preliminary results show how defects like warping and missing material caused strain to decrease. Followed by strain evolution for specimens with different thicknesses which revealed maximum strain for the …

Computational investigation of flahover mechanisms using fire dynamics simulator (fds)
… of 20kW/m2 at the floor level and average upper layer temperature of 600℃ were, in most cases appropriate regardless of ceiling height and the configuration of ventilation. However, the results suggest that a ceiling temperature of 600 °C is not a good general criterion for flashover. With …

Empirical and experimental studies of flashover in compartment fire
… of thermal inertia of lining materials on temperature history and the development of enclosure fires when changing vent size. A fresh regression analysis was performed to update the MQH method to include modem compartment materials with a wider span of thermal inertia. Some theoretical …

The simulation of fire growth and spread within enclosures using an integrated CFD fire spread model
… of the radiative properties of gas-soot mixture, temperature calculation for non-burning solid surfaces, etc. into a complete fire spread model. Shortcomings in the conventional six-flux radiation model are highlighted. These were demonstrated through a simple artificial test case and corrected in …

Quantitative modelling of spatial variability in the north Atlantic spring phytoplankton bloom
… of the annual plankton cycle in the ocean mixed layer. The model is optimised to fit survey data from the eastern North Atlantic, collected over a 1500 x 1500 km area between 39N and 54N, from April-June 1991, establishing the feasibility of using spatially distributed point-in-time data in model …

The generation of carbon monoxide in compartment fires
… first principles. Studies of simplified upper layer environments have shown that major species production rates can be correlated with the equivalence ratio in what is known as the Global Equivalence Ratio concept (GER). Due to the simplification in these past experiments, it was not known if …

Investigation of primary productivity along the Atlantic Meridional Transect (50°N to 33°S) through fast repetition rate fluorometry
… of water mass characteristics in the upper 200 m layer. Temperature versus salinity diagrams were plotted at each station and further analyses of nitrate and chlorophyll were carried out for confirmation of the provinces. The structure of phytoplankton community and its distribution were assessed …

Finite Element Analysis of Thermal Buckling in Automotive Clutch and Brake Discs
… of finite element method. It is found that the temperature distribution along the radius and the thickness affects the critical buckling load considerably. The results indicate that a monotonic temperature profile leads to a coning mode with the highest temperature located at the inner radius. …
