Traffic simulation represents an effective tool for evaluating the suggested alternatives to enhance traffic conditions prior to their application in real sites. U-turn sections represent examples of the complicated sections that cannot be analyzed properly without applying microsimulation approach.  Recently, in Iraq, speed humps were applied in prior to the merging locations and U-turn sectio...

Left-turn crashes occur frequently at signalized intersections and often lead to severe injuries. This problem can be addressed through the implementation of protected left-turn signals. This gives left-turning vehicles the right to enter the intersection free from conflict with opposing drivers and pedestrians. The present study analyses the effect of this measure on crash occurrence. The stud...

A 56-year-old woman complained of recurrent attacks of vertigo. Attacks lasted no longer than a second and could be easily provoked by abrupt eye movements. Vertigo disappeared when the left eye was covered. Symptoms had begun after left-sided cataract surgery resulting in subluxation of the left lens. The characteristic feature of iridodonesis is the tremulousness of the iris with eye movement...

The Diamond booster and storage ring are equipped with Libera Electron Beam Position Processors with turnby-turn capabilities. We describe here the turn-by-turn data acquisition system and the software used for postprocessing the beam data. The signals from the Libera boxes are acquired and controlled with EPICS and then transferred to the MATLAB environment via the MATLAB Channel Access or Lab...

A turn-by-turn vertical beam profile monitor has been developed at the Cornell Electron Storage Ring (CESR). The instrument optically images the vertical beam distribution with an array of optical fibers that transport visible synchrotron radiation to an array of photo-multiplier tubes. Each PMT signal is recorded by a turn-by-turn data acquisition system. With this instrument, we compare profi...

A human-like driving model can help to improve the acceptance and safety of automated systems (ADS). To performance interaction with conventional vehicles ADS, speed behavior left-turn at signalized intersection was studied using natural data. In this study, 374 valid data points snippets intersections were extracted three phases introduced based on reaction braking, stopping, accelerating in p...

As an unconventional design to alleviate the conflict between left-turn and through vehicles, Continuous Flow Intersection (CFI) has obvious advantages in improving sustainability of roadway. So far, manuals guidelines for CFI are not enough sufficient, especially displaced lane length CFI. And results existing research studies operational, making it difficult put into application. To address t...

abstract. let r be a 2-torsion free ring with identity. in this paper, first we prove that any jordan left derivation (hence, any left derivation) on the full matrix ringmn(r) (n  2) is identically zero, and any generalized left derivation on this ring is a right centralizer. next, we show that if r is also a prime ring and n  1, then any jordan left derivation on the ring tn(r) of all n×n up...

Awareness of self-generated movements arises from comparing motor plans, and the accompanying (hypothetical) efference copy, with the visual and proprioceptive consequences of movement. Here we used repetitive transcranial magnetic stimulation (rTMS) to investigate the role of a posterior region in the superior parietal lobule (SPL) in this process. Nine healthy volunteers performed a finger ex...
