Study on Thermal-Hydraulic Behavior of an Integral Type Reactor under Heaving Condition

open access: yesScience and Technology of Nuclear Installations, 2014
A self-developed program was used to study the thermal-hydraulic behavior of an integral type reactor under heaving condition. Comparison of calculated results with the data of experiments performed on a natural circulation loop designed with reference ...

Implementation of probabilistic approach to rock mass strength estimation while excavating through fault zones [PDF]

open access: yes, 2019
Purpose. The paper addresses the rock mass state estimation while excavating a cross-heading through the area of regional fault “Bohdanivskyi” based on probabilistic approach to assessing the rock strength. Methods.

Coupled Aerodynamics–Structure Analysis and Wind Tunnel Experiments on Passive Hinge Oscillation of Wing-Tip-Chained Airplanes

open access: yesAerospace
This study examines the wing hinge oscillations in an aircraft concept that employs multiple wings, or small aircraft, chained at the wing tips through freely rotatable hinges with minimal structural damping and no mechanical position-locking system ...

Thermal modeling of Anchorage driveway culvert with addition of insulation to prevent frost heaving [PDF]

open access: yes, 2017
A predominate problem in cold regions, and specifically in Anchorage, Alaska, is frost heaving pavement above culverts in residential driveways. The culvert increases heat loss in the subgrade materials during winter months and allows the soils below ...

An Investigation into Power from Pitch-Surge Point-Absorber Wave Energy Converters. [PDF]

open access: yes, 2007
There is a worldwide opportunity for clean renewable power. The results from the UK Government's "Marine Energy Challenge" showed that marine energy has the potential to become competitive with other forms of energy.

Point absorber wave energy converters in regular and irregular waves with time domain analysis [PDF]

open access: yes, 2016
A discrete control of latching is used to increase the bandwidth of the efficiency of the Wave Energy Converters (WEC) in regular and irregular seas. When latching control applied to WEC it increases the amplitude of the motion as well as absorbed power.

Frost heaving of foundation pit for seasonal permafrost areas

open access: yesИнженерно-строительный журнал, 2019
Frost heaving can cause support structures to crack and even instability of the foundation pit. This paper describes the frost heaving features of the steel pile pre-stressed tendon composite foundation pit support system (SPPTCFPSS). As a combined rigid–
