in addition to increment of the vehicle sprung mass, the main physical effects of addition of cng tank to the vehicle are the longitudinal and height displacement of center of gravity, which have the most influences on the handling, braking, roll stability and spin stability of the vehicle. increment of cng tank mass to the sprung mass of the vehicle increases the vehicle under-steer gradient, ...

conclusions to solve the above mentioned difficulties, fundamental study most be carried out to discover the novel methods of ferrate(vi) production, focusing on increasing the product stability and the production yield. results despite the existence of these technologies, there is no full-scale application of ferrate(vi) in the water and wastewater industry which it is due to difficulties asso...

M often employ market response models as decision aids and historical information of competitors’ market outcomes to aid their competitive decisions in oligopolistic settings. However, little is known about how access to a decision aid or the availability of competitors’ market outcomes impact a firm’s competitive decisions (e.g., prices) or market outcomes resulting from those decisions (e.g.,...

This paper examines whether consumers necessarily benefit from tightening the price cap. We find that a tighter price cap always increases consumer welfare when demands are independent. Conversely, when demands are interdependent a tighter price cap may reduce consumer welfare.  2000 Elsevier Science S.A. All rights reserved.

The directed search model (Peters, 1984) is static; its dynamic extensions typically restrict strategies, often assuming price or match commitments. We lift such restrictions to study equilibrium when search can be directed over time, without constraints and at no cost. In equilibrium trade frictions arise endogenously, and price commitments, if they do exist, are self-enforcing. In contrast to...

A commonly-used and naive solution to process data with missing attribute values is to ignore the instances which contain missing attribute values. This method may neglect important information within the data, significant amount of data could be easily discarded, and the discovered knowledge may not contain significant rules. Some methods, such as assigning the most common values or assigning ...
