The length of an acceleration lane is one the dominant freeway geometric design parameters. This requires new analyses to anticipate needs heavy commercial vehicle (HCV) platooning. We evaluated safety and operational impact HCV platooning on for a ramp in Ontario, Canada. study modified 2018 AASHTO’s estimation analytical model. Furthermore, this used VISSIM micro-simulation model surrogated a...

metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...

-This paper evaluates suitable voice-data length in IP packets for the adjustment of VoIP network systems. Based on measurements in a real environment, we examined the voice-quality level while varying the voice-data length of IP packets under various network conditions. We found that a VoIP system with long-voice data has high-transmission efficiency but there is a high deterioration in the vo...

OBJECTIVE To identify key factors for predicting positive cone margin and appropriate cone length. METHODS We retrospectively reviewed the margin status of patients who received conization with high grade cervical intraepithelial neoplasia, along with other factors such as patient age, parity, preoperative cytology, size of disease, type of transformation zone, and cone length from patient re...

BACKGROUND To define appropriate antibiotic use for patients with a complicated urinary tract infection (UTI), we developed in a previous study a key set of 4 valid, guideline-based quality indicators (QIs). In the current study, we evaluated the association between appropriate antibiotic use for patients with a complicated UTI, as defined by these QIs, and length of hospital stay (LOS). METH...

This paper proposes a suitable method for simulating impulses with appropriate amplitude, spectral, and inter-arrival characteristics. The statistics used to develop the parameters of this model are based on statistics derived from observations of impulse noise on the telephone networks of British Telecom (BT) and Deutsche Telekom (DT). This paper initially reviews the former DT approach to imp...
