For choosing the most optimal energy source, is necessary to know different parameters, which an operator could not process all at the same time or have not known them. The goal of the present study is to obtain the best selection of a series of alternatives, under different criteria in which the user could to select the most appropriate when uncertainties or doubts arise between each of the alternatives. multicriteria method helps to describe and analyze the problem of interest and to support the making decisions.","PeriodicalId":169028,"journal":{"name":"INNOVATION & DEVELOPMENT IN ENGINEERING AND APPLIED SCIENCES","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125442900","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 effort was carried out under empiric-analytic approach, of descriptive type. The object population of the study was the web apps developed as a grade works in Systems Engineering's program of Nariño University the years between 2010 and 2017. As a result, web apps were characterized, bearing in mind the variables: quantity, technology, economic sector, development time, involve and current state. Was identified 71 grade works that developed web apps, where PHP is the back-end language used and a high level does not identify the use of front-end frameworks. In intermedium level, the web apps were developed by one student only. In a high level the web apps were to public entities, being the sectors: education, government and service; the most bounties. The work enables us to conclude that the lowest use of web apps, obey to the relation between software architecture and usability. The intermediate use of back-end web frameworks and the low level of use of front-end frameworks, is a factor that decreases the flexibility to implement usability architectonic tactics a web app. Moreover, teamwork has to be encouraged and propitiate, when software is build.","PeriodicalId":169028,"journal":{"name":"INNOVATION & DEVELOPMENT IN ENGINEERING AND APPLIED SCIENCES","volume":"31 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116285119","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}

Within this area, we know that security is framed within the CIA triangle, which refers to confidentiality, integrity and availability of information or objects connected to the Internet, a subject that should be treated with great awareness. There were some questions that we inevitably must ask in order to understand at a deeper level the different aspects of information security, such as: What is an object? How safe is our private information? What privacy settings do we have? We live in an interconnected world where most of devices at home, businesses, industries, organizations, and cities are connected to the Internet. Within that environment, these objects are fulfilling some functionality that facilitates the lives of each individual, although making them somehow dependent on this technology with a high degree of risk to which they are exposed. This study aimed to explain and demonstrate that most of electronic devices or intelligent objects that are developed, locally or overseas, do not have a proper design with regard to making information security a first priority, then, proposing a guiding scheme that allows an adequate development cycle of intelligent objects. The study concluded that we are not 100% safe, as well as cyber-attacks will continue to evolve, so the conception of information security will have to evolve as well.","PeriodicalId":169028,"journal":{"name":"INNOVATION & DEVELOPMENT IN ENGINEERING AND APPLIED SCIENCES","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114402928","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}

Based on the methodologies developed, there is a model developed in multinational company of consumer products dentered on the OTB, PMBOK and Lean Six Sigma methodologies. This model has been successfully implemented in: Brazil, Mexico, Argentina and Colombia. The execution includes the following stages: identifying which products or stock keeping units in the warehouse can be standardized, designing packaging prototypes of packages or boxes that can be reused from the manufacturers of raw materials until the finished product and that can be used for reuse in packaging of other similar products, quality tests are executed in order to ensure the strength and longevity of the boxes. As a result of its implementation, an increase of financial efficiency was obtained for the company in case, , reducing its logistics costs in comparison with the sales revenues by around 8%, as well as a significant improving of its environmental management.","PeriodicalId":169028,"journal":{"name":"INNOVATION & DEVELOPMENT IN ENGINEERING AND APPLIED SCIENCES","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129483078","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}

For this purpose, the stresses analysis was carried out in a hole concentrator subjected to traction. The model's material was ASTM A36. The stresses were analytically calculated, through von Mises' theory. In addition, the analysis of the stresses using the finite element method (FEM) was carried out. Subsequently, displacements and unitary deformation were determined in the part. The results obtained report an error of 8.7% between the stresses of von Mises through analytical calculus and using the FEM.","PeriodicalId":169028,"journal":{"name":"INNOVATION & DEVELOPMENT IN ENGINEERING AND APPLIED SCIENCES","volume":"39 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120917162","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}
