    Robust design of CAV-Dedicated lanes considering CAV demand uncertainty and lane reallocation policy

    No full text
    Reduced headways of connected and automated vehicles (CAV) provide opportunities to address traffic congestion and environmental adversities. This benefit can be utilized by deploying CAV-dedicated lanes (CAVDL). This paper presents a bi-level optimization model that captures CAV market size uncertainty. The upper level determines the links (and number of lanes) for CAVDL deployment to minimize emissions. It considers lane reallocation policies that account for the prospect of smaller width of CAV-dedicated lane due to the smaller lateral wander of CAV tire tracks. This can increase the total number of lanes on wide highway sections. At the lower level, equilibrium and demand diffusion models capture travelers’ route and vehicle-type choices. The bi-level model is formulated as a min–max mathematical program with equilibrium conditions and solved using the cutting-plane scheme and active-set algorithm. The computational experiments indicate that the robust plans have superior performance compared to the deterministic plan in pessimistic cases.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Plannin

    Robust Design of Electric Charging Infrastructure Locations under Travel Demand Uncertainty and Driving Range Heterogeneity

    The rising demand for electric vehicles (EVs), motivated by their environmental benefits, is generating an increased need for EV charging infrastructure. Also, it has been recognized that the adequacy of such infrastructure helps promote EV use. Therefore, to facilitate EV adoption, governments seek guidance on continued investments in EV charging infrastructure development. Such investment decisions, which include EV charging station locations and capacities, and the timing of such investments require robust estimates of future travel demand and EV battery range constraints. This paper develops and implements a framework to establish an optimal schedule and locations for new charging stations and decommissioning gasoline refueling stations over a long-term planning horizon, considering the uncertainty in future travel demand forecasts and the driving range heterogeneity of EVs. A robust mathematical model is proposed to solve the problem by minimizing not only the worst-case total system travel cost but also the total penalty for unused capacities of charging stations. This study uses an adaptation of the cutting-plane method to solve the proposed model. Based on two key decision criteria (travelers' cost and charging supply sufficiency), the results indicate that the robust scheme outperforms its deterministic counterpart.

    Authorship attribution on Urdu corpus using lexical, syntactic and stylistic features

    No full text
    Authorship attribution has deep roots in linguistic Stylometry. Stylometry is the linguistic information to label documents whose authors are unknown by using the writing style of the possible suspects. Traditional authorship attribution systems rely on the specific vocabulary and writing style of the author. In my study, I have performed two experiments and compare both the experiment and discuss the outcomes. Both experiments examine the performance of the model using the combination of lexical, syntactic and stylistic features. In experiment 1, the performance of Naïve Bayes, Support Vector Machine and Random Forest is examined and in experiment 2, the deep learning model is applied and its performance is judge using the traditional approaches in experiment 1

    People with non-congenital physical disabilities tend to experience depression due to traumatic events that affect their physical changes. So there needs to be a process to accept one's condition so that individuals can overcome the depression they are experiencing and have a purpose in life. This research aims to determine the process of self-acceptance and the problems experienced by people with non-congenital physical disabilities at UPT RSBD Pasuruan. To obtain data for this research, the author used a descriptive qualitative approach which helped the author to explain in more detail the content of the research. In this research, researchers also used observation, interview and documentation techniques. The results of this research show that the process of self-acceptance experienced by the subject goes through the stages of Aversion, Curiosity, Tolerance, Allowing, and Friendship. Each individual has different stages. The factors that support self-acceptance include understanding themselves, realistic expectations, identification of people who are able to adapt, and supportive social behavior

    Mood Influences Working Memory Capacity

    No full text
    abstract: Working memory is the cognitive system responsible for storing and maintaining information in short-term memory and retrieving cues from long-term memory. Working memory capacity (WMC) is needed for goal maintenance and to ignore task-irrelevant stimuli (Engle & Kane, 2003). Emotions are one type of task-irrelevant stimuli that could distract an individual from a task (Smallwood, Fitzgerald, Miles, & Phillips, 2009). There are studies that show there is a relation between emotions and working memory capacity. The direction of this relationship, though, is unclear (Kensinger, 2009). In this study, emotions served as a distractor and task performance was examined for differences in the effect of emotion depending on participants' working memory capacity. The participants watched a mood induction video, then were told to complete a complex-span working memory task. The mood induction was successful- participants watching the negative emotional video were in a less positive mood after watching the video than the participants that watched a neutral video. However, the results of the complex-span working memory task showed no significant difference in the results between participants in the negative versus neutral mood. These results may provide support to an alternative hypothesis: cognitive tasks can diminish the effects of emotions (Dillen, Heslenfeld, & Koole, 2009).A copy of this thesis/creative project may be available at Barrett, the Honors College at Arizona State University.
