The present study was performed to investigate the effect of commercial and operational factors on competitiveness improvement of Shahid Beheshti Port (SBP) in Chabahar in attracting shipping lines. The research method is applied in terms of purpose. Initially, the researcher conducted the qualitative phase to identify important variables, create a typology, or make new theories. To reach the s...

considerable investments have been made in establishing wastewater treatment plants (wwtps). however, evaluation of the performance of plants during recent years, when more wwtps have become operational, shows that effluent quality criteria were not met in many instances. preliminary assessment of the operational problems of wwtps in iran disclosed that numerous factors affect this issue of eff...

Operating parameters and membrane characteristics strongly affect the performance of electrodialysis reversal systems. The most impactful factors are applied voltage, flow rate, temperature, initial feed composition, and ion exchange membrane characteristics; the pH of the feed also has an effect, although to a lesser extent. To determine more precisely how all of these factors impact performan...

Operational speed is an index that represents drivers’ speeding behaviors and shows the comfort and safety levels they experience. Many models had been proposed to predict operational speed in tangent and curve segments of highways. Most of these works had used geometric, with few of them conducted using roadside variables to predict operational speed. Also, the operational speed study in multi...

The first type of definition was common in the 1970s but has proved largely useless for design purposes since it offers neither useful guidance for designers nor perspective for evaluators. The feature-based approach stems from the longstanding desire to specify in advance desirable interface attributes that enhance usability. However, this type of definition rests on an assumption that usabili...
