Abstract—Our goal is to utilize microorganisms as micro-robots by using galvanotaxis (locomotor response to electrical stimulus). To reach this goal, motion control in three-dimension must be achieved. Our group has proposed a novel three-dimensional tracking system incorporating the Depth-From-Diffraction method, the lock-on tracking and high-speed vision. In this paper, we control the motion ...

Scalable architectures with non-uniform memory access time (NUMAs) have gained increased popularity in recent years. The increased scalability have increased the demand for scalable lock implementations, such as the queue-based locks of Mellor-Crummey and Scott (MCS lock), and of Craig, Landin and Hagersten (CLH lock). This paper demonstrates that the first-come first-served nature of queue-bas...

The transition to multicore processors has brought synchronization, a fundamental challenge in computer science, into focus. In looking for solutions to the problem, interest has developed in the lock-free approach, which has been proven to achieve several advantages over the traditional mutual exclusion approach. This thesis studies challenges in interprocess synchronization in shared memory m...

A lock placement describes, for each heap location, which lock guards the location, and under what circumstances. We formalize methods for reasoning about lock placements, making precise the interactions between the program, the heap structure, and the lock placement.

The changing three-dimensional vortex shedding topology of a heavy, tethered sphere exposed to uniform flow crossing the onset induced vibrations (VIV) is reported together with simultaneously tracked positions. Transient upstream conditions were imposed by increasing reduced velocity from $U^{*} = 2.2$ 4.5 (‘lock-in’, mode I). Three-dimensional under these transient strongly resembled those at...

abstract background: despite advances in the field of intravenous therapy, phlebitis is still a common complication of peripheral venous catheter and finding an appropriate solution to prevent and reduce the incidence of this complication remains challenging. one of the methods used in reducing the incidence of phlebitis is the use of saline lock, which is forgotten in most hospitals. therefore...

OBJECTIVES The purpose of this study was to explore phase reset of 3-dimensional current sources in Brodmann areas located in the human default mode network (DMN) using Low Resolution Electromagnetic Tomography (LORETA) of the human electroencephalogram (EEG). METHODS The EEG was recorded from 19 scalp locations from 70 healthy normal subjects ranging in age from 13 to 20 years. A time point ...

BACKGROUND The suction sockets that are commonly prescribed for transtibial amputees are believed to provide a better suspension than the pin/lock systems. Nevertheless, their effect on amputees' gait performance has not yet been fully investigated. The main intention of this study was to understand the potential effects of the Seal-in (suction) and the Dermo (pin/lock) suspension systems on am...
