This paper presents a comparative localization study of wireless sensors in a complex environment, an underground mine, based on the received signal strength (RSS). Three estimation algorithms are tested to localize sensors in this harsh environment; the maximum likelihood estimation (ML), the two-step weighted least squares estimation (TWLS), and the generalized total least squares estimation (GTLS). The propagation model used in this work is obtained from conducted experimentation in a real mine environment. To the best of our knowledge, no comparative study was done between different localization algorithms in a mine environment. The aim of this work is to show the importance of the suitable choice of localization technique in difficult propagation conditions, allowing afterwards use and enhancing it depending on propagation parameters.","PeriodicalId":153723,"journal":{"name":"2023 Fifth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123095449","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}

These objectives, as well as the development towards the digitalization of the building portfolio, have prompted the need for more intelligent, adaptable, and proactive buildings. In light of this, a building automation and control system (BACS) which is well-designed, built, and run properly is essential for attaining environmental and energy efficiency goals, as well as for delivering high levels of comfort and providing the building's occupants with the needed valuable information. In this study, the design functions and services offered by the automation and control system are assessed using an innovative platform called IBACSA for BACS assessment and building smartness evaluation. The platform evaluates eight different technical building domains that span 60 major building services, reports the rating and performance of each domain, and considers various impact criteria into account. Three Danish buildings of various types, sizes, and uses are considered as a case study to implement IBACSA. In each instance, the BACS design and functions are assessed and graded, and recommendations for improvement are highlighted.","PeriodicalId":153723,"journal":{"name":"2023 Fifth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124851089","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}

These temperatures are raising cooling costs and leading to power outages worldwide. Phase Change Materials, known as PCM, if incorporated correctly in the concrete pavement mix, can lead to the mitigation of UHI by lowering surface and air temperatures. In this paper, a case study of a busy street in Rotterdam city, with an area of over 60% pertaining to concrete pavement, was simulated using Envi-Met software. The thermal properties of the resulting mix were used. The results were promising, showing a decrease in the surface temperature of almost two degrees Celsius during the day. As it is known that every one degree lowering of temperature is equivalent to 6% to 10% of electrical energy savings, then the effect of PCM incorporation also alleviates CO2 emissions and yields cost savings.","PeriodicalId":153723,"journal":{"name":"2023 Fifth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126778138","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}

A grounding system composed of four vertical cylindrical rods in a homogeneous and heterogeneous soil was used. The obtained results show the distribution of the voltage in the ground as well as the computed value of the resistance of the electrodes.

The obtained results showed that a significant hydrogen purity of 66 mol% can be obtained using equilibrium reactor with recycle compared to 50 mol% using plug-flow reactor. The proposed PFR design was also compared to a similar work in literature involving catalytic operations. As a result, the effectiveness of conventional reactors in the non-catalytic production of synthesis gas with significant hydrogen purity has been proven, presenting an advantage over the catalytic processes represented by the avoidance of the challenges associated with catalytic reactions, such as pressure drop and catalysts deactivation.","PeriodicalId":153723,"journal":{"name":"2023 Fifth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131515099","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 suggested evaluation method aims at qualifying three levels (layers) of intelligence from passive behavior (communication layer) to representative layer (physical) and predictive behavior (scheduling layer). These levels should be interpreted through 3 dimensions: time, space and energy. The analytical evaluation used SPSS from the intrinsic data of the building extracted by ArcGIS software in order to make buildings intelligent based on dynamic scheduling or optimization algorithms.

The measured thickness is utilized to instantly modify stapling and cutting depths. Bariatric surgery is intended to help people with obesity to lose excess weight and reduce your risk of potentially life-threatening weight-related health problems. This surgery must be safe and completed quickly in order to reduce the risk of developing and experiencing possible side-effects that can sometimes be fatal. Due to this, the linear stapler endocutter, which is the surgical tool used to conduct the surgery, must accurately measure the height of the tissues to be sleeved to ensure a perfect b-shape staple has been put in place. This helps to prevent any dangerous and risky blood leakage, thus allowing a short recovery stay at the hospital. In this paper, we report a PID model of a digital caliper to be embedded in linear staplers currently available in the market to ensure a correct measurement of tissue thickness is taken and consequently an appropriate staple fitting the height of the tissue has been used. The digital caliper will work to stop the firing of the stapler in case the measurements are not correct fit thus preventing any further damage to the tissues from the extra staples and preventing the need for additional firing with the staples.","PeriodicalId":153723,"journal":{"name":"2023 Fifth International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127543196","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}
