We characterise nth order ODEs for which the space of solutions M is equipped with a particular paraconformal structure in the sense of [2], that is a splitting of the tangent email [email protected] email [email protected]

The emission and mitigation of greenhouse gases transforms the status urban environments. However, a policy accounting for all aspects associated with transport is lacking. Problems related to include greater reliance on cars, increased congestion, environmental impacts. absence an efficient public system notable cause prompt escalation diverse problems, example, increases in number personal au...

In the wake of decreasing urban development space in China, regeneration has gradually changed from incremental renewal to stock renewal. Looking back on past process renewal, we can find that “Transit-oriented Development” (TOD) plays an essential role modern Therefore, this study, explain concept and principles TOD discuss logic addition, summarize basic features strategy based through analys...

Construction of a hybrid strain which is capable of mineralizing components of a benzene, toluene, and p-xylene mixture simultaneously was attempted by redesigning the metabolic pathway of Pseudomonas putida. Genetic and biochemical analyses of the tod and the tol pathways revealed that dihydrodiols formed from benzene, toluene, and p-xylene by toluene dioxygenase in the tod pathway could be ch...

The choice of a representation i.e. the deeni-tion of the search space, is of vital importance in all Evolutionary Optimization processes. In the context of Topological Optimum Design in Structural Mechanics, this paper investigates possible representations for evolutionary shape design. The goal is the identiication of a shape in IR n (n = 2 or n = 3) having optimal mechanical properties. Evol...

We construct infinitely many seven-dimensional Einstein metrics of weak holonomy G2. These metrics are defined on principal SO(3) bundles over four-dimensional Bianchi IX orbifolds with the Tod-Hitchin metrics. The Tod-Hitchin metric has an orbifold singularity parameterized by an integer, and is shown to be similar near the singularity to the Taub-NUT de Sitter metric with a special charge. We...
