Smooth delivery of customers or goods increases the company competitiveness. Analysis of overcrowded roads and traffic routes that impose major problems for traffic planning teams requires the evaluation of traffic burstiness. In many everyday situations such as rush hours in the morning or evening, the traffic appears bursty that creates so-called bottlenecks. Here the microscopic modelling of stochastic processes with measurable parameters has to be implemented in order to find optimization approaches for avoiding or smoothing bottlenecks. An efficient but simple way to model bursty traffic is to use gap distribution functions describing statistically the gaps (distance) between the neighbouring cars. However, suitable gap distribution functions have to be found as the common assumption of an exponential distribution of the gaps does not allow for any bursty traffic modelling. In this work a traffic model based on gaps is introduced, and ways to estimate the parameters of the stochastic system such as the car intensity and the car burstiness are given. The model is validated by a typical traffic light situation. Our results for a given car intensity and car burstiness in a street segment with one obstacle show that a longer green phase and a shorter red phase of the traffic light is an efficient way to decrease car burstiness.","PeriodicalId":396821,"journal":{"name":"2023 International Interdisciplinary PhD Workshop (IIPhDW)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117115561","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 Big Bang-Big Crunch (BB-BC) optimization algorithm based two new approaches to feature selection for dimensionality reduction. In first approach, PCA is used to extract the features (eigenvectors) and defines feature set based on computation of knee point and BB-BC optimization algorithm, in turn selects an optimal subset from the predefined feature set. In the second approach, PCA is used only for feature extraction and BB-BC optimization algorithm is used for optimal feature selection from all extracted features. Olivetti Research Laboratory (ORL) face database has been used for performing the experiment and recognition rate is the parameter to be optimized for face recognition as an application area. The experimentation proves BB-BC as a powerful soft computing technique to solve such NP hard problems.","PeriodicalId":396821,"journal":{"name":"2023 International Interdisciplinary PhD Workshop (IIPhDW)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122800856","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}

Unfortunately, current FES controllers cannot simultaneously satisfy the competing demands of high accuracy, robustness to modelling error and minimal set-up/identification time that are needed for clinical or home deployment. To address this, an estimation-based multiple model switched iterative learning control framework is proposed, combining the most successful adaptive and learning properties of existing FES controllers. A practical design procedure guaranteeing robust performance is developed, and initial experimental results are then presented to confirm efficacy of the approach.","PeriodicalId":396821,"journal":{"name":"2023 International Interdisciplinary PhD Workshop (IIPhDW)","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132073664","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}

Women in the AEC fields is still undiscussed in African context. Therefore, this paper aims to cast light on this topic, fill this knowledge gap. Based on a survey involving African 121 male and female operators in north African AEC fields, this research investigated the females” integration in both office and construction site positions and revealed four categories of key obstacles hindering women's inclusion and retention: behavioral, cultural, personal, and organizational that involve a total of 11 key obstacles with on the top “Underestimation, presumptions, and sexual harassment by male colleagues or hierarchy”, The paper suggested 5 sections including 16 remedial actions: legal, organizational, personal, technological, and financial.

Based on a simple current-controlled stimulator design, an analog control loop is integrated into the feedback loop of the boost converter to manipulate the high-voltage generation. In that way, the output voltage is only as high as necessary to drive any desired pulsed current through tissue with variable impedance. The efficiency for the generation of monophasic stimulation pulses could be improved by about 50 %. Another advantage is the circuit's simplicity. The added voltage control loop has only a few additional components, is easy to understand, and therefor perfect for small, battery operated devices, where runtime is an important factor.","PeriodicalId":396821,"journal":{"name":"2023 International Interdisciplinary PhD Workshop (IIPhDW)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121996216","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}

By finding errors in air conditioning systems, the involved company “Dr. Diestel GmbH” is able to offer optimization of the systems with low investment techniques to their customers. The process of diagnosis starts with the modelling of the investigated system and determination of measuring points. Sensors using the LoRaWAN technology are placed at these positions to measure and upload the data to the cloud. Different cloud services process the data to determine ways of optimization. To simplify and centralize the management of the used devices an application is developed, that will handle the registering of the devices in the cloud services and give an overview of a system and its measuring points. By comparing different cloud services and application frameworks, it was possible to create an easy-to-use and reliable system that handles the data flow and processing from the sensor to the diagnosis tool and guides the technician in placing and managing the sensors on site.","PeriodicalId":396821,"journal":{"name":"2023 International Interdisciplinary PhD Workshop (IIPhDW)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126434637","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}
