[1] A new mechanism is proposed to explain the 100,000-year timescale for variations in Antarctic temperatures and atmospheric CO2 over the last 650,000 years. It starts with fluctuations in the oceanic overturning around Antarctica that release CO2 up to the atmosphere or trap it in the deep ocean. Every 50,000 years one of these fluctuations coincides with a changeover in the burial of CaCO3 ...

Optimal load of mobile robots, while carrying a load with predefined motion precision is an important consideration regarding their applications. In this paper a general formulation for finding maximum load carrying capacity of flexible joint mobile manipulators is presented. Meanwhile, overturning stability of the system and precision of the motion on the given end-effector trajectory are take...

elevated water tanks as one of the main lifeline elements are the structures of high importance. since they are extremely vulnerable under lateral forces, their serviceability performance during and after strong earthquakes is a matter of concern. as such, in recent years, the seismic behavior of water tanks has been the focus of a significant amount of studies. in the present work, three reinf...

[1] We use a global Ocean-Atmosphere General Circulation Model (OAGCM) to show that the major mountain ranges of the world have a significant role in maintenance of the Atlantic Meridional Overturning Circulation (AMOC). A simulation with mountains has a maximum AMOC of 18 Sv (1 Sv = 10 m s ) compared with 0 Sv for a simulation without mountains. Atlantic heat transport at 25°N is 1.1 PW with m...

The problem of calculating the equatorial damping moment during trajectory flight is an actual inballistic studies rotational motion artillery projectiles. practice ballistic research needs short algorithmsthat make it possible to calculate together with calculations parametersunder conditions continuously changing characteristics oncoming flow. In this regard, a simplified methodfor projectile...

Generally, only wind effect is considered in the collapse evaluation of transmission poles (TPs). However, during a typhoon landing, rainfall usually very heavy and influence should be simultaneously. To estimate bearing capacity TPs accurately typhoon, this paper proposes method for predicting water content distribution soil based on deep learning method. Then, earth pressure related to obtain...

(5) The limited access zone shall remain in place until the wall is adequately supported to prevent overturning and to prevent collapse unless the height of wall is over eight feet, in which case, the limited access zone shall remain in place until the requirements of paragraph (b) of this section have been met. (b) All masonry walls over eight feet in height shall be adequately braced to preve...

In addition to the mean meridional Hadley circulation, there also exist zonal overturning circulations that contribute to the meteorology and climatology of the tropics. Together, these overturning circulations are commonly referred to as the Walker circulation. In this section, we first explore the history and basic structure of the Walker circulation. Later, we reintroduce the shallow water e...
