Numerical analysis and improvement of torsional vibration of shaft systems for engine with cylinder deactivation

, 2014
Cylinder deactivation is one of effective ways to improve fuel economy of engine, but will lead to changes in torsional vibration characteristics of shaft systems for engine.

On Oxalyl Halide Isothiocyanates Part I: Syntheses and Isomerism

European Journal of Inorganic Chemistry, EarlyView.
Oxalyl halide isothiocyanates can be prepared from oxalyl halide with one equivalent of NH4SCN in liquid SO2. While oxalyl bromide isothiocyanate can be isolated as a liquid, the respective chloride compound readily undergoes isomerization under formation of a thiazole ring, which is obtained as a solid.

Dilithium Enediamide Derived From a 1,4‐Diaza‐1,3‐diene: Reactivity of a Strongly N‐Basic, Highly C‐Nucleophilic Compound Toward C–H Acids

European Journal of Inorganic Chemistry, EarlyView.
The lithium enediamide complex 2 with intrinsically inverted C–N bond polarity combines strong basicity with unusual reactivity: deprotonation of malonates enables C–C bond formation without electron transfer. Depending on malonate substitution, electrophilic substitution or addition occurs at the enediamide CC bond.

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...
