The process of obtaining accurate value for physical and thermodynamical properties of hydrocarbons is getting more challenging in the case of multicomponent non ideal systems. The purpose of this work is applying the kernel ridge regression (KRR) in the form of the recently developed truncated regularized kernel ridge regression (TR-KRR) algorithm to estimate z-factor. Compared to the support vector machines (SVM), the KRR algorithm is just as accurate as, but faster than SVM.","PeriodicalId":432120,"journal":{"name":"2019 Fourth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116112822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mathematical model of the circuit is presented where the pinched hysteresis loops (PHLs) with different periodic stimuli are analyzed. The numerical, P-Spice simulations and experimental results are presented indicating that the introduced emulator is a simple voltage-controlled generalized inverse memristor. The results show that the PHLs area is increased with increasing the applied frequency. In addition, the proposed emulator is employed in a simple chaotic circuit. The effect of the inductor's values on the chaotic system is investigated and the P-Spice simulations are performed to approve the numerical results.","PeriodicalId":432120,"journal":{"name":"2019 Fourth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"3 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127467577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traveler's mode choice takes into consideration the main factors affecting their decision making. The aim of this research study is to investigate the factors affecting the mode choice of Notre Dame University-Louaize (NDU) students. A Multinomial Logit Discrete choice approach is used to model the student's choice to commute to NDU between the available transport modes, private cars, shared taxis, taxis and public buses. The model results show that NDU students are mostly affected by the income, travel cost, and travel time. After the mode choice model is developed for NDU students, a comparison analysis is done between on the model developed for NDU students and another model developed for American University of Beirut (AUB) students, including a value of time (VOT) analysis. Results show that AUB students have resulted in a different mode choice model and higher value of time than NDU students.","PeriodicalId":432120,"journal":{"name":"2019 Fourth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125465786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides the efficiency experienced by other public transport modes like buses and rail system, while offering the more preferred experience of an automobile. This research paper concentrates on analyzing the effects different system variables (ie, berths, speed, headway, and mode share) have on the PRT efficiency within an urban area. The system efficiency is determined based on several key performance indicators, such as the average waiting time, percentage of people who have to wait for a vehicle, how long they have to wait on average for the vehicles and the empty to full distance ratio. These indicators are obtained from the simulations results. The urban setting was chosen to be Beirut Central District (BCD), due to its crucial economic well-being for the country of Lebanon and to its current need of an efficient public transport system. PRT alignments was designed with stations locations determined based on, existing right-of-way, the land-use and the density of the area. For most of the parameters, the speed had potent effect on the results, while the mode share altered the values majorly, which was expected. However, with regards to the other variables, no correlation was witnessed.","PeriodicalId":432120,"journal":{"name":"2019 Fourth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121259325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a review of the path planning optimization problem, and an algorithm for robot path planning in a static environment, using genetic algorithm as a tool. The purpose of the algorithm is to find the fastest route in a given number of steps, while avoiding obstacles in the space. The algorithm's performance is enhanced by automatically omitting all suggested routes that cross the boundaries of the environment. For optimization and search problems, genetic algorithms are used as a search tool in computing to find exact or an approximate solution. The algorithm is tested with number of steps less, equal, and more than the sufficient steps needed. The results show how the number of steps in different environments set the best path to be followed.","PeriodicalId":432120,"journal":{"name":"2019 Fourth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130167506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we analyse different electrical parasitic equivalent circuit models in the aim of comparing them and selecting the one that can best describe and represent the physical properties of our high-performance VCSELs.
