Modeling complex systems plays a significant role in decision supports for stochastic processes such as the transportation system. Furthermore, the transportation system in an urban university setting poses additional challenges due to the dynamic nature of the user groups (mainly students) as many factors including the living arrangements and class schedules of the students influence the demands for on-campus transportation. In this research initiative, a university shuttle system was simulated using discrete event simulation modeling to understand the systems dynamics, identify system bottlenecks, and recommend improvement strategies. Specifically, the passenger waiting times as well as the shuttle bus utilization were analyzed at each bus stop. After modeling and validating the current transportation system scenario, a hypothetical scenario of diverting buses from one route to another was investigated and quantitative comparison was made.

The key role played by the circuit-breaker in power systems combined with the increasing importance of the constancy in the power delivery has made non-invasive techniques fundamental for evaluating circuit-breaker status, namely its breaking capacity by including any minor likelihood of arc reignition, which has shown as being far from feasible through power system modelling and computer simulation, due to the inherent complexity of the adjacent power circuits to be correctly modelled. Alternatively, radiometric techniques have experienced an increasing interest which reasons range from the non-invasive principles to the programmability in its execution. On the other hand, much is to be done before such techniques may be widely adopted, especially for the difficulties in properly capturing the correct triggering signal. Based on this scenario, this work presents a brief review of this relatively recent technique and points out items to which researchers should drive their efforts to overcome the related barriers to overcome. © 2022 IEEE.

This research initiative focuses on modeling and optimizing an urban university parking system. Different from regular parking systems, urban university parking systems face additional challenges due to the limited space, the complexity of the parking facility distribution, the dynamic nature of the traffic flows, and the randomness of the parking access times, primarily driven by class schedules. A comprehensive discrete event simulation model was developed to capture parking system dynamics for an urban university in Akron-Ohio. Specifically, a model consisting of 7 parking decks, 44 surface lots, and 8 residence halls was created to take into account the different user groups, their arrival and departure patterns, and parking location preferences. After validating the baseline model, an interactive campus map was developed to show the best places to park throughout the day based on the windows of arrival times on campus. This map can be updated each academic semester based on the arrival rate data for parking location recommendations.

Given a set of underwater sensors coordinates that are usually determined by a specialist for the design of a watershed monitoring system, where should be placed the sinks and the base station? The answer may be the minimization of the Variable Internode Distance. In such cases, a two dimensional architecture is acceptable because it is a shallow water system. Hence, in this paper, it is proposed a two-level node distance minimization for Underwater Wireless Sensor Network for monitoring systems. The mathematical method employed for optimization is the Hyperbolic Smoothing approach and the proposed method includes the placement of the base-station in the algorithm. Copyright 2014 ACM.

Redundancy in patent abstracts, that is, the repetition of an International Patent Classification tag or patent class information across documents, poses a challenge in patent classification, which is essential for efficiently managing the growing number of patent documents. This study aims to develop a model to analyze the weights and index values of summary sentences to improve the efficiency and accuracy of patent classification. This model can predict relevant patent data types. Utilizing logistic regression and the one-vs-rest method, this study focuses on the development of models to analyze the weights and index values of summary sentences, with the goal of enhancing the precision and efficiency of patent classification. The main contribution of this research is the creation of predictive models for new patent documents to streamline patent citations based on document type. This study also serves as a reference for evaluating Indonesian patent document classification models, thereby facilitating the patent evaluation process. © 2023 IEEE.

The pandemic significantly affects the tourism industry due to health risks and travel conditions. The study aimed to identify the travel preference of Filipinos amidst the pandemic through Applied Conjoint Analysis. Several attributes such as Location, Ambiance, Pre-Departure COVID-19-19 Test, Quarantine Requirements, Insurance Policy, and Type of Tour were analyzed simultaneously. A total of 61 Filipinos answered an online questionnaire which was distributed by a convenience sampling approach. The results demonstrate that Quarantine requirements are an essential attribute that influenced the decision of Filipino travelers. The study can be used for future studies about travel trends due to the pandemic. © 2023 IEEE.

Depression rate has reached 17-27% in Indonesia, while about 5-10% of world population have sleep disorder. Unsurprisingly, one of the symptoms of depression is sleep disorder. Sleeping disorder could be treated by sleeping mask. The material of sleeping Mask is PLA (polylactic acid) in 3D printing. There is Arduino Uno as microcontroller to control alarm for sleep-wake cycle. Device works until the first 30 minutes for blue LED and delta binaural beats and the last 30 minutes for yellow LED and gamma binaural beats.. Blue LED and delta wave of binaural beats can stimulate the delta brainwave which related with deep sleep. While yellow LED and gamma binaural beats could stimulate the gamma brain waves and trigger awakening. This research employs causal quantitative method with experimental primary data collection. Additionally, there are two tests in this research, namely sleep and awakening test. A delta wave stimulation is shown in lead C3-C4 during the sleep test. Stimulated delta wave records 23.42 times higher rate than without stimulation. Thus, the system can actually trigger a deep sleep faster. During the awakening test, the stimulation using gamma binaural beats and yellow light shows that delta brainwave amplitude in lead C3-C4 is lower;while alpha brainwave amplitude in lead O1-O2 is higher. Thus, this system is able to stimulate alpha wave faster than without stimulation. The mask could regulate sleep-wake cycle for alarm device and enhance sleep quality. © 2018 University of Dicle.
