A solar thermal accumulator is designed and built using the phase change principle, to optimize the drying process in a familiar solar dryer, in an additional period to the cessation of the incidence of solar radiation; the phase change material selected is the commercial paraffin, whose thermal properties have been characterized by the KD2 Pro meter. The melting temperature of the paraffin (53 oC) is around the operating temperature of the medium temperature solar dryer. The solar thermal accumulator is characterized by being modular, consisting of twelve cylindrical units of recycled aluminum, where each unit contains 200 g of paraffin and incorporates meshes with aluminum fins to improve the flow of heat to the outside and optimize its transfer to the air. As a result, the additional drying time has been increased by an order of 2 hours without intervention of solar radiation, maintai...

One of the factors that determine the productivity inside a company is the state of the machinery with which is counted for the production. Our objective was to design a system that allows the engineers to supervise and to evaluate the state of the machinery, so that this in sot only repaired when it doesn't work, but rather one has the possibility to take a periodic registration of the operation of the same one. With it, it'll be possible to identify the flaws of the machinery in their diverse evolutionary phases. This will allow to carry out an appropriate correction of the problem diminishing the maintenance cost and, therefore, to stop the machinery for a smaller period of time. The system that we have designed in compound for a card of acquisition that will allow to capture and to transfer the mechanical vibrations of the machinery toward analysis software that allows the engineers ...

This article intends to explain the different possibilities of representation of what we will call “fictional ecosystems”, being imaginary ecosystems that are developed through visual representation, highlighting their importance to establish, develop and maintain a connection with the inhabited territory, as fundamental relationship to build a society that questions the subjectivities established in the coexistence with the natural, humanized and collective environment. Thus, an explanatory line is developed, which answers the following question, can elements of visual representation be used for the creation of “fictional ecosystems” that help to question the relationship that we build with our natural and humanized ecosystems in the contemporary environment and its corresponding problems? The answer is built through a methodology created using two phases of analysis. An explana...

Traditional construction and property companies often find themselves bound by conventional project management and design techniques, which can lead to delays during the design phase. This situation needs to be avoided. This study presents a process optimization for the design stage of multifamily buildings using Virtual Design Construction (VDC) - a collaborative project management approach. Focused on a case study involving two residential buildings developed by the same property company in Lima, Peru, this research commences with a comprehensive analysis of the existing design processes from the projects. By pinpointing key sources of variability and streamlining the design flow, the proposed VDC implementation aims to enhance compliance with project timelines and the approval of design drawings. The optimized process yielded tangible results, significantly reducing design time, compl...

It is attempted to show the possibilities of symbolic representation under an interdisciplinary approach, from Art and Architecture applied to the peripheral problems of the environment and to their reconstruction from the territory, evidencing a symbolic heritage based on the production of cartographies that show ethical-aesthetic values as a possibility of representation of the visual memory contained in the belonging processes occurring in the city of Metropolitan Lima.How could we view these reconstruction processes made by our memory around the spaces where we live and participate or how could migration paths be evidenced from that perspective? A methodology is proposed based on three phases of recognition of a personal route of rearrangement of individual history which starts from topographic knowledge of the territory in the reconstruction of personal experiences, to develop then ...

The construction industry is essential for the economic development of a country. However, changing management in these projects can be complex due to communication between different stakeholders. Construction changes are common and can occur at any stage of the project, which can have negative impacts on costs and schedules. It is important to have clear communication of the vision and benefits of changes before implementing them. The use of Information and Communication Technologies (ICT) in construction can improve communication, collaboration, knowledge management, and acquisition processes. In this context, a change management model is proposed in the design phase of infrastructure works based on the BIM (Building Information Modeling) and ICE (Interactive Concurrent Engineering) methodologies. The model is divided into six phases: search and compilation of information, analysis of ...

The technology developed in the last years benefits several industries while improving margins and indicators. This is the case of the BIM tool, virtual reality (VR) and augmented reality (AR). In the construction industry, project managers are more reluctant to using these new technologies, wasting the opportunities of improvement they give. The use of BIM in construction projects has been boosted in the last years, obtaining very good results by integrating it to the Lean Construction philosophy. However, the implementation of visualization tools like VR and AR it’s still on the first phase of research. On this thesis, the state of the art of virtual reality, augmented reality and its application on the construction industry is reviewed and determined. From there, a case study on the design phase of a heritage structure project is done, to evaluate and validate its use during the des...
