PIER: Internet Scale P2P Query Processing with Distributed Hash Tables by Ryan Jay Huebsch Doctor of Philosophy in Computer Science University of California, Berkeley Professor Joseph M. Hellerstein, Chair Distributed database systems have long been a topic of interest in the database research community. Existing designs focus on two principles; make the distribution transparent to users and pr...

By considering the near-field vertical seismic spectrum and calculating change in contact force between main beam pier, possible separation condition of a bridge is deduced. extreme value pier–beam longitudinal deformation pier under structural separation, influence on failure determined. Separation increases risk compression, bending, shear, different times lead to responses from first mode di...

OBJECTIVE This study examined whether the incidence of hospitalization for psychosis was reduced by a communitywide system of early identification and intervention to prevent onset of psychosis. METHODS The Portland Identification and Early Referral program (PIER) was initiated in 2001. Youths and young adults ages 12-35 were identified by professionals in a wide variety of educational, healt...

The experimental seismic testing of a 1/5-length scale model, slender bridge steel truss pier was conducted to investigate the use of a controlled rocking approach as a means of seismic protection. The controlled rocking approach allows the pier to uplift from its base, partially isolating the structure, while passive energy dissipation devices (steel yielding devices, fluid viscous dampers) ar...

Base-level fall in river beds occurs due to varying natural or unnatural causes. Base-level fall causes the change in the behavior of flow at the location of drop in base-level. In such situations, most of scour occur at the foot of the slope, and slope wall retreats in the upstream direction. This phenomenon widens the wall of the river bank, thus leading to its destruction. The amount of bed ...

Identification of the nonlinear hysteretic behavior of a reinforced concrete (RC) bridge pier subjected to earthquake loads is carried out based on acceleration measurements of the earthquake motion and bridge responses. The modified Takeda model is employed to represent the hysteretic behavior of the RC pier with a small number of parameters, in which the nonlinear behavior is described by var...

Wilson The content of In the Clinic is drawn from the clinical information and education resources of the American College of Physicians (ACP), including PIER (Physicians’ Information and Education Resource) and MKSAP (Medical Knowledge and Self-Assessment Program). Annals of Internal Medicine editors develop In the Clinic from these primary sources in collaboration w...

Based on the high-pile and high-pier bridge of Qianhuang Expressway, eigenvalue buckling analysis is carried out by establishing three-dimensional finite element models three different types types, corresponding structural nonlinear loads under initial pier deviations are calculated. The calculation results show that less than elastic loads. stability column continuous better simple supported b...
