Determining frost heave classification by using ratio of frost heave to square root of time
Yantu gongcheng xuebao, 2023 The frost heave classification is the critical index for the design of foundation engineering in cold regions. At present, it is considered as a basic property of materials. Many criteria belong to empirical or semi-empirical methods and lack theoretical

High-Power Hybrid Nanogenerator With Multi-Degree-of-Freedom Mechanical Coupling for Harvesting Water Wave Energy. [PDF]
Adv Sci (Weinh)A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Motion of Floating Caisson with Extended Bottom Slab under Regular and Irregular Waves
Journal of Marine Science and Engineering, 2021 Floating caissons may oscillate primarily due to ocean waves during towing operations. Reducing the oscillation based on the extension part (footing) of the bottom slab of the caissons can efficiently increase the safety of towing maneuvers. However, the

Effects of transient temperature gradient on frost heave of saturated silty clay in an open system
Research in Cold and Arid Regions, 2023 Frost heave in seasonally frozen regions is a one-dimensional process that could severely damage infrastructure subgrades. Stress state, temperature and water migration are important factors for frost heave.

Heave Motion of a Vertical Cylinder with Heave Plates [PDF]
Polish Maritime Research, 2021 Abstract The shape of a vertical cylinder resembles the classic form of a spar platform. Spar platforms are floating platforms that are successfully used in waters of great depths and have several advantages that mean they are readily used in the oil industry.

Study on the effect of vehicle transient posture on brake feeling
Nihon Kikai Gakkai ronbunshu, 2020 In evaluating the brake feeling of passenger cars, it is known that vehicle postures such as pitching and heave influence other than the relationship between pedal depression force and stroke and deceleration.
