Our location in the world makes us a country with a high seismic risk. Taking into account that the information produced during a seismic event is of vital importance for the study carried out by seismology, it is necessary to use the appropriate type of instrumentation to record these data. Currently, electronics provides the necessary technology for the study of phenomena of this type. The design and construction of a Digital Accelerograph will allow us to carry out a detailed study of a seismic movement and the effect caused on the structure of buildings. Finally, we can say that the construction of an instrument of this type at a low cost will allow repowering and increasing the CISMID accelerographic network and, in general, improve the knowledge of seismic phenomena at the national level.

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 ...

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...

The Peruvian AEC industry has started implementing VDC and BIM in public projects due to recent regulations that state the progressive adoption of BIM (as a methodology) in public construction. Regardless of the benefits of these new approaches, some challenges to VDC implementation have emerged as a response to the resistance to change of the Peruvian AEC industry, which is stronger in the Peruvian public sector. The aim of this paper is to present the challenges found in the author´s VDC implementation experience in a public project, as part of the third VDC Certificate Program in Lima lead by CIFE from Stanford University. These challenges will be identified based on a schema, constructed by the literature review. The results show that the main challenges found are the lack of commitment and the lack of collaboration between stakeholders. These results suggest the need to overcome th...

The concept of soundscape was incorporated in the late 1960s, from the field of acoustics and music, to address the problem of excessive noise in cities and disorderly urban planning, which has led to residential areas ‒which are supposed to be quiet‒ are juxtaposed with commercial and/or production activities that degrade the quality of hearing life. Starting in 2002, it was realized that the concept of soundscape could also be used as a tool to build a sound identity, whether to preserve historical sound environments, rescue “lost” sound activities from anthropology or create auditorily healthy zones within the cities. Barcelona is the first city that took the initiative to establish large blocks in order to reduce urban noise based on the particular acoustic study of each neighborhood, defining a differentiated sound landscape to preserve. Since 2012, acousticians from all ove...

Quinoa (Chenopodium quinoa) is one of the main grains of a domesticated species native to the high Andean plains and valleys. Because its harvests do not always have a homogeneous color, some companies have been using sorting machines for quinoa that are adapted from other cereals, whose operation does not guarantee the desired efficiency. The purpose of the study was to design and build a prototype machine that classifies quinoa grains according to the desired color. The main parts of the machine include the design of the mechanical structure comprising three zones: feeding, transport and processing and storage. The parts were built with steel materials and some parts with PLA filament manufactured with 3D printer; electronic control system, using a microcontroller for adapting the IR sensor signal and controlling the electro actuators for the selection of homogeneous quinoa according t...

The construction of an electrolytic reactor for its use in a laboratory with the possibility of varying the number of electrodes, simultaneously the volume capacity of the electrolytic, and its application to a gamma of electrosynthesis process, has determined the election of a rectangular model, so in this way it can be defined the operative variables when addressing a specific process. The job requirements were taken into account during the design, which were the operational simplicity, the maintenance reliability, and the faculty to fit easily taking into account all the involved costs. Therefore, the election of a filter press type modular cell will allow increasing the number of electrodes and the capacity as it is required, without changing its dimensions.

Learning-centered models, which rely on active methodologies such as Project-Based Learning (PBL), should be adopted in undergraduate programs to potentiate the development of collaboration skills within future industry professionals like civil engineers. Thus, this study reports the implementation of PBL in two successive Virtual Design and Construction (VDC) courses from an undergraduate civil engineering program: 1) VDC I, in which the VDC methodology implementation was applied theoretically in an already-built project, and 2) VDC II, in which the VDC methodology implementation was applied in a currently-under-construction project. The study's objective is to identify students' perceptions of PBL influence on their learning experience, degree of acquisition of generic competencies, and project development under the VDC methodology. To assess the PBL and VDC implementation, a survey wa...
