The careful design of a regulated, efficient, scalable and portable bioreactor system for the analysis of an ever-growing variety of biological and chemical processes is currently of paramount importance for the development of Biotechnology. The existing mutual interaction of the variables involved hinders the optimization of the system and urges the need to embed it with high performance and adaptability against changes in response to different characteristics. In this paper is proposed a validated method for the regulation of the bioreactor’s agitation speed and temperature as well as compound pH by traditional techniques based on ON-OFF, integrators, derivatives and Fuzzy controls. The resulting control system enables its configuration and supervision either locally or remotely with encryption, managing the content stored and exchanged between devices.
精心设计一个可调节、高效、可扩展和便携式的生物反应器系统,用于分析不断增长的各种生物和化学过程,目前对生物技术的发展至关重要。所涉及的变量之间现有的相互作用阻碍了系统的优化,并促使需要以高性能和适应性嵌入系统,以应对不同特征的变化。本文提出了一种基于on-OFF、积分器、导数和模糊控制的传统技术来调节生物反应器的搅拌速度、温度以及化合物pH值的有效方法。由此产生的控制系统能够通过加密在本地或远程进行配置和监督,管理设备之间存储和交换的内容。

Diseño de planta y equipo para la revalorización de residuos sólidos 固体废物回收厂及设备设计
IF 0.2 Pub Date : 2020-06-29 DOI: 10.36561/ing.18.5

This project presents the design, technical and economic evaluation of a food solid waste revaluation plant through the separation of food from its packaging and subsequent composting of the food waste; with a strong emphasis on the design of the unpacking equipment, which processes the containers so that they can later be recycled. Besides, the production of compost from organic solid waste is presented as a way of revaluation of the organic fraction, which replaces the most widely used method of waste disposal in our country, the landfill. Although composting does not offer great profits, as a counterpart it doesn’t have great associated costs and reduces the environmental impact compared with the most common method of waste disposal in the country, making it an attractive alternative. The project proposes to process 370 tons of food waste per month, generating 180 tons of compost per month, quality A or B. Regarding packaging, the alternatives analyzed for recycling were not economically viable, so it’s proposed to compact and dispose it on sanitary landfill. Although this isn’t the expected treatment, it reduces the environmental impact with respect to the disposal of the original waste. Finally, it is concluded that given the current conditions and the prices observed in the market, the project is technically but not economically viable.
该项目通过将食品从包装中分离出来并随后对食品垃圾进行堆肥,介绍了食品固体废物再利用工厂的设计、技术和经济评估;重点是开箱设备的设计,该设备对容器进行处理,以便以后可以回收。此外,利用有机固体废物生产堆肥是一种重新评估有机成分的方法,它取代了我国最广泛使用的废物处理方法,即填埋。尽管堆肥不会带来很大的利润,但与国内最常见的废物处理方法相比,堆肥没有很大的相关成本,并减少了对环境的影响,使其成为一种有吸引力的替代方法。该项目建议每月处理370吨食物垃圾,每月产生180吨堆肥,质量为A或B。关于包装,分析回收的替代品在经济上不可行,因此建议将其压实并在卫生填埋场处理。虽然这不是预期的处理方法,但它减少了原始废物处理对环境的影响。最后,得出的结论是,考虑到目前的条件和市场上观察到的价格,该项目在技术上是可行的,但在经济上是不可行的。

espanolRecientemente los sitios web de los gobiernos en el mundo han sido objeto de ataques informaticos. Por ello urge una solucion que asista a los analistas de ciberseguridad a detectar los incidentes con rapidez. Para optimizar el tiempo de deteccion en el proyecto se desarrollo un clasificador que filtre lineas de logs de servidores web en formato CLF (Combined Log Format) que indican comportamiento anomalo. Para ello, se codifican los logs de acceso en representacion vectorial y luego se usa el algoritmo de aprendizaje automatico K-NN ponderado (K vecinos mas proximos) para filtrar los logs. Los datos de entrada fueron provistos por el CERTuy (Equipo de Respuesta ante Emergencias Informaticas) y el SOC (Centro de Operaciones de Seguridad). De las pruebas realizadas sobre el servicio de clasificacion, se detecto el 82% de ofensas de ciberseguridad de un conjunto de datos asociado, se logro filtrar el 80% de logs que indican comportamiento normal y se disminuyo el tiempo de deteccion de logs que indican comportamiento anomalo de 13 horas a 15 minutos. EnglishThe number of attacks on government websites has escalated in the last years. In order to assist in the detection process conducted by cybersecurity analysts, this document suggests implementing machine learning techniques over web server access logs. The overall objective is to optimize the detection time using a customized classifier which selects traces corresponding to anomalous activity. Specifically, web server combined log format (CLF) access logs coded as real vectors are an input to a weighted K-NN nearest neighbors’ model. The methodology was tested on datasets and premises provided by the CERTuy (National Cybersecurity Event Response Team) and the SOC (Security Operations Center). According to evaluations 82% of cybersecurity offenses have been detected, 80% of normal behavior has been filtered and the reduction time has been reduced from 13 hours to 15 minutes.
最近,世界各地的政府网站都受到了网络攻击。因此,迫切需要一个解决方案,帮助网络安全分析师快速检测事件。为了优化项目中的检测时间,我们开发了一个分类器,该分类器以CLF(组合日志格式)格式过滤显示异常行为的web服务器日志行。为此,我们将访问日志编码为向量表示,然后使用加权K- nn机器学习算法(K个最近的邻居)过滤日志。输入数据由CERTuy(计算机紧急响应小组)和SOC(安全操作中心)提供。clasificacion检测服务,拾起了82%的网络安全犯罪相关联的一组数据显示,80%实现过滤logs正常行为和disminuyo时间成为logs表示anomalo行为13小时15分钟。在过去的几年里,针对政府网站的攻击数量有所增加。为了协助网络安全分析师进行的检测过程,本文建议通过web服务器访问日志实现机器学习技术。总体目标是优化检测时间,使用定制分类器选择与异常活动相对应的轨迹。为此,web server logs combined log format (CLF) access coded as real载体are an input to a weighted K-NN nearest在“model。该方法在CERTuy(国家网络安全事件响应小组)和SOC(安全行动中心)提供的数据集和设施上进行了测试。根据评估,82%的网络安全犯罪被发现,80%的正常行为被过滤,减少时间从13小时减少到15分钟。

The urban heat networks (District Heating, DH) combined with the use of renewable energies, such as the biomass of agricultural waste, have been consolidated as an important tool for energy efficiency and the reduction of the emissions of greenhouse gases in the United States and the countries in the north and center of Europe. The objective of the networks for the thermal distribution is to offer a service of air conditioning (comfort heating and cooling) and the production of sanitary hot water for the residents of the different buildings of an area connected to the network, guaranteeing better energy efficiency and quality of service with respect to what would be obtained from individual installations. If the use of an energetic waste to produce heat, is added to the possibility of placing cogeneration plants (with a production comfort heating and cooling and electric power), the district heating business becomes even more prosperous. In the present paper, after a long review of the state of the art of heating of the Biomass District Heating, the technical implications of the equipment of a thermal power plant and the agricultural activity of Uruguay, a practical solution is proposed to be replicated in all the small communities of the country. For this solution, three particular crops residues - soybean, grape and olive residues –are used.
城市供热网络(区域供热,DH)与可再生能源(如农业废物的生物质)的使用相结合,已成为美国和欧洲北部和中部国家提高能源效率和减少温室气体排放的重要工具。热分配网络的目标是为连接到网络的区域的不同建筑的居民提供空调服务(舒适的供暖和制冷)和生产卫生热水,从而保证从单个装置获得更好的能源效率和服务质量。如果利用高能废物产生热量,再加上建立热电联产厂(具有生产舒适的供暖、制冷和电力)的可能性,区域供暖业务将变得更加繁荣。在本文中,在对生物质区域供暖的最新技术、火力发电厂设备的技术影响和乌拉圭的农业活动进行了长期回顾后,提出了一个可在该国所有小社区推广的实用解决方案。对于这种解决方案,使用了三种特定的作物残留物——大豆、葡萄和橄榄残留物。

In Brazil, some industries with high consumption of water are developing optimization strategies to prevent or minimize the impact of potential new cost on spring water. The model obtained for the minimization of the water consumption and its operation cost in a soft drink manufacturing facility is NLP and no convex one. This paper shows the results of the application of General Bender´s Decomposition algorithm, to a superstructure optimization problem. The use of the GBD algorithm allow nevertheless a global optimal solution which outcome was a water distribution structure with less cost than the one obtained with a traditional NLP solver -local optimum at higher cost. The solver was GAMS ® / with BDM-LP and Minos ®. A global optimum with the values for a structure, that allows a 17% cost reduction, was obtained in less than one second.

A global optimum with the values for a structure, that allows a 17% cost reduction, was obtained in less than one second.","PeriodicalId":42925,"journal":{"name":"Memoria Investigaciones en Ingenieria","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76123974","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 parallel with the technical challenges related to Industry 4.0, a challenge arises about how to prepare current and future workers so that they can adapt to future jobs, which will demand new requirements in terms of competences and skills. The main objective of this paper is to investigate which competences will be essential towards the future jobs in the agro-industry sector. The investigation was focused in this sector, since is one of the economic sectors with the greatest risk of job automation. An extensive literature review, followed by in depth interviews to relevant stakeholders in the agricultural sector in Uruguay were conducted in order to identify the main competences considered critical towards the future. In particular, radar graphs were created, showing the actual and expected level of development of 31 professional competences, divided into four main categories. The competences acknowledged by the stakeholders as most relevant for the future are: IT knowledge, Ability to interact with modern interfaces, Active Learning, Analytical and Logical Thinking, Oral expression, Teamwork, Trust in technology and Flexibility.
与工业4.0相关的技术挑战同时出现的一个挑战是,如何培养当前和未来的工人,使他们能够适应未来的工作,这将对能力和技能提出新的要求。本文的主要目的是调查哪些能力对农业工业部门未来的工作至关重要。此次调查主要集中在这一领域,因为这是工作自动化风险最大的经济领域之一。为了确定被认为对未来至关重要的主要能力,进行了广泛的文献综述,随后对乌拉圭农业部门的相关利益攸关方进行了深入访谈。特别是制作了雷达图,显示了31项专业能力的实际和预期发展水平,分为四个主要类别。利益相关者认为与未来最相关的能力是:IT知识、与现代界面交互的能力、主动学习、分析和逻辑思维、口头表达、团队合作、对技术的信任和灵活性。
