A key aspect of cloud computing is the promise of infinite, scalable resources, and that cloud services should scale up and down on demand. This thesis investigates methods for dynamic resource allocation and management of services in cloud datacenters, introducing new approaches as well as improvements to established technologies. Virtualization is a key technology for cloud computing as it al...

IMPORTANCE Estrogen therapy is the gold standard treatment for hot flashes and night sweats, but some women are unable or unwilling to use it because of associated risks. The serotonin-norepinephrine reuptake inhibitor venlafaxine hydrochloride is used widely as a nonhormonal treatment. While the clinical impression is that serotonin-norepinephrine reuptake inhibitors are less effective than es...

A variety of faults may cause performance degradation or even downtime of virtual machines (VMs) under Cloud environment, thus lowering the dependability of Cloud platform. Detecting anomalous VMs before real failures occur is an important means to improve the dependability of Cloud platform. Since the performance or state of VMs may be affected by the environmental factors, this article propos...

The ventral striatum (VS) is a key brain center regulating reward-oriented behavior [1-4]. The VS can be anatomically divided into medial (VMS) and lateral (VLS) portions based on cortical input patterns. The VMS receives inputs from medial pallium-originated limbic structures (e.g., the medial prefrontal cortex [mPFC]), and the VLS receives inputs from the lateral pallium-originated areas (e.g...

System virtualization allows resources of a single physical machine to be shared among multiple virtual machines (VMs). This can increase system flexibility, but it can also invalidate some assumption that the OS running in a VM has about the system it is executing on. This paper surveys the implementation of symmetric multiprocessing (SMP) in a virtualized environment. It examines two proposal...

A feedback control algorithm for Variable Message Sign (VMS) of Urban Network is proposed. And traffic signal coordination with VMS is explicitly considered in the proposed VMS control algorithm. It is generally true that feedback control approach requires low computational effort and is less sensitive to model’s inaccuracy and disturbance uncertainties. Several issues in VMS control are raised...

The variational multi-scale (VMS) method for large-eddy simulation (LES) is a promising new approach that employs variational projection to achieve a priori scale separation in lieu of traditional spatial filtering. However, depending on the numerical method used, VMS may not be practicable in all spatial directions. We apply the VMS methodology to a numerical method that does not support expli...

OBJECTIVE This study aims to determine the efficacy of exercise training for alleviating vasomotor and other menopausal symptoms. METHODS Late perimenopausal and postmenopausal sedentary women with frequent vasomotor symptoms (VMS) participated in a randomized controlled trial conducted in three sites: 106 women randomized to exercise and 142 women randomized to usual activity. The exercise i...

Online learning and virtualization are two key and complementary technologies which are increasingly used for today’s education missions. Online learning offers great accessibility to a variety of educational materials and activities, whereas virtualization allows a variety of educational software to be easily distributed using virtual machines (VMs). However, in current practice, the use of VM...

The effectiveness of Variable Messages Signs (VMS) on route guidance is assessed by a discrete probit choice model that estimates the proportion of vehicles that diverts to an alternative routes given the characteristics of different messages. A before–and–after study is also conducted to quantitatively evaluate the network wide reduction of travel time and total delay of VMS systems. We find t...
