The integrated braking control system (IBC) has become one of the most popular brake-by-wire (BBW) solutions due to its compactness and versatility. Accurate monitoring wheel cylinder pressure in real time is basis for brake control, estimation a low-cost reliable method. However, IBC an electromechanical hydraulic coupling that significant nonlinear behaviors; moreover, vehicle dynamics also h...

This paper measures the unilateral incentive each of the five largest electricity suppliers in California had to exercise market power in the state’s wholesale market during the four-month period from 1 June to 30 September of 1998, 1999, and 2000. Using the actual bids submitted to the California Independent System Operator’s (CAISO) real-time energy market, I compute the hourly price elastici...

Given a set of jobs, each consisting of a number of weighted intervals on the real line, and apositive integer m, we study the problem of selecting a maximum weight subset of the intervalssuch that at most one interval is selected from each job and, for any point p on the real line,at most m intervals containing p are selected. This problem has applications in molecularbiology, ...

BACKGROUND The prevalence of obesity increased while certain measures of physical fitness deteriorated in preschool children in China over the past decade. This study tested the effectiveness of a multifaceted intervention that integrated childcare center, families, and community to promote healthy growth and physical fitness in preschool Chinese children. METHODS This 12-month study was cond...

We present two-dimensional inviscid hydrodynamic simulations of a protoplanetary disk with an embedded planet, emphasizing the evolution of potential vorticity (the ratio of vorticity to density) and its dependence on numerical resolutions. By analyzing the structure of spiral shocks made by the planet, we show that progressive changes of the potential vorticity caused by spiral shocks ultimate...

This paper introduces a case study on the potential of new mechatronic chassis systems for battery electric vehicles, in this brake-by-wire (BBW) system and in-wheel propulsion rear axle combined with an integrated control providing common safety features like anti-lock braking (ABS), enhanced functionalities, torque blending. The presented controller was intended to also show continuous strate...

In this paper we describe block algorithms for the reduction of a real symmetric matrix to tridiagonal form and for the reduction of a general real matrix to either bidiagonal or Hessenberg form using Householder transformations. The approach is to aggregate the transformations and to apply them in a blocked fashion, thus achieving algorithms that are rich in matrix-matrix operations. These red...
