It should be easy to use and cost effective so most of the users can get it. This article presents the analysis of the problem, the design proposal, prototyping and test results of the development of a wireless temperature monitoring system in a domestic water heater tank. This device allows knowing the temperature of the heater in real time by using IoT (Internet of Things) technology. It uses the device's internal memory where machine learning algorithms customize settings that can trigger intelligent alarms such as water leak detection, under or over temperature, and efficiency loss. The device delivers the data to the user or to other devices (for further automation) by local Wi-Fi. The scalable architecture of IoT allows adding extra measurements for physical phenomena that affect the heater's performance, such as water flow, sun radiation and outdoor relative humidity. Those measurements can be easily integrated in a more complex system version for commercial or industrial customers.","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122600840","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}

Therefore, it is proposed to implement the Lean methodology, focusing directly on the optimization of production processes using its various tools and a selection of indicators for monitoring the results. To validate, a case study was carried out in a real company that implemented the different Lean tools and the Kaizen matrix in the dyeing and finishing process, a process that presents a high percentage of defects. This allowed us to effectively reduce the number of reprocesses by a significant 8.14%, which allowed the company to save $ 184,320.42.","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125678298","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 PBR is possible to control the conditions of the culture, with the purpose of increasing the production of biomass or metabolites. The relation between the conditions of growth with the light intensity is essential for the increase of biomass. This paper describes the application of a Proportional-Integral-Derivative controller to control the light intensity within the broth in a batch culture of the Acutodesmus obliquus (Scenedesmus obliquus UTEX 393). The performance of the PID controller was tested with laboratory-level experiments using violet light. In the experiments, conventional lighting operation was compared with constant lighting inside the broth. The experimental results showed an increase in the percentage of lipid production compared to cultures where the intensity of light was not constant (conventional lighting).","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132203110","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}

Some of the most current designs have robust models capable of alerting seismic events before they are perceptible to people. Hence, this article presents an early notification seismic alarm system based in Internet of Things, focusing on the use of a SigFox network for the integration between an electronic prototype, data monitoring and seismic warning, in order to make it interoperable with existing systems. The system's tests demonstrated stable and reliable communication, along with a processing algorithm capable of detecting seismic signals that alerts the population 8 seconds after the arrival of the primary waves of an earthquake, giving more time to the evacuation process.","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132063165","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}
