  • Rural and small libraries: The tribal experience

    Jenkins, Jennifer L.; Quiroga, Guillermo; Quiballo, Kari; Peterson, Herman A.; Sorrell, Rhiannon (Emerald Group Publishing Ltd., 2017-01-01)
    This chapter discusses some of the challenges faced by tribal libraries. Considering the information provided throughout the rest of this volume, it is clear that some of the core issues-such as poor broadband availability, difficulties in achieving economies of scale, and barriers to collaboration-are shared between tribal institutions and rural libraries throughout the United States. The chapter presents a brief review of the literature on tribal libraries, establishing how they compare with rural public libraries in the United States. The remainder of the chapter is designed as a conversation piece, with responses from interviews with librarians from two tribal libraries detailing how the challenges faced by these outlets parallel those faced by America's rural libraries. • Tribal libraries face obstacles that are common among nontribal rural public libraries, such as poor broadband Internet availability, lack of funding, and geographic barriers that limit patron access. • Although public libraries exist in some tribal communities, other forms of libraries and cultural heritage institutions often fill the service roles that public libraries occupy in nontribal communities. • Public-oriented information institutions in tribal communities commonly preserve and promote tribal heritage, often as one of their primary purposes. Considering that this is often achieved on limited budgets, further documentation of these efforts could be useful for guiding nontribal rural public libraries that wish to do more to preserve and promote their local cultural heritage. This study creates bridges between rural public libraries in the United States and tribal libraries, which are commonly studied as two separate phenomena. Although the authors document how these types of institutions differ from each other in significant ways, barriers of broadband access, geographic isolation, and lack of funding are common across both rural and tribal libraries. The information provided in this chapter shows that both types of institutions need solutions for similar problems.

    Nuñez-Castaneda, Yaninna; Moreno-Samanamud, Manuel; Shinno-Huamani, Miguel; Maradiegue-Tuesta, Fernando; Alvarez-Merino, Jose (Institute of Electrical and Electronics Engineers Inc., 2019-10-01)
    The wholesale trading companies are facing new challenges in terms of the level of service, which is an important factor which determines the level of sales and profitability of companies. Thus, currently, companies are aimed to deliver orders to their respective customers on time, in good condition and complete. This file focuses on the importance of warehouse management for mass consumption distributors, since it's the warehouses that determine the operation and productivity costs of these. Thus, some innovative techniques such as the lean warehouse and allocation tools improve working conditions with the aim of reducing downtime and distances. A pilot programme of implementation of the tools mentioned in the warehouse of a wholesale distributor was carried out. As a result of the research, the distance traveled in the warehouse was reduced by 22%, the reduction of times in the picking process, achieving the optimal delivery time and generating an increase in the sales made of 215,720.22 soles. These results prove to be decisive in the performance of the supply chain (inventory, cost, delay and risk), since the key to success for this industry is to satisfy the needs of customers in the shortest possible time.

  • A Pilot Study on Subtitling Tasks and Projects for Intercultural Awareness and Queer Pedagogy

    Villanueva-Jordan, Ivan; Gallardo-Echenique, Eliana (Institute of Electrical and Electronics Engineers Inc., 2020-10-19)
    This paper presents the results of a pilot study on the use of active interlingual subtitling for intercultural awareness and queer pedagogy. The subtitling tasks and project were carried out with Ooona, an online subtitling software, and as part of an optional course on gender and sexuality at an undergraduate university program in Translation. The data collected are based on the Spanish subtitles produced by the students from audiovisual content originally in English, as well as on questionnaires and reports that they completed after subtitling. The results reveal how cloud-based subtitling software is a useful tool for students to position themselves regarding online video content online, as well as how the audiovisual representation of queer characters allows students to reflect on aspects of the gender/sex system when they must transfer linguistic content that is rooted in different socio-cultural systems.

  • Optimization of the design process in construction projects by the implementation of the A360 collaboration tool

    Arevalo, Jennifer; Palacios, Mauricio; Rodriguez, Sandra; Farje, Julio (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    Each year there are more construction companies seeking for implementation of the Building Information Modeling (BIM) methodology in their projects since it provides different benefits related to project time, cost and quality. Besides, different countries currently demands its application. However, companies do not always achieve these benefits at its totality because BIM implementation must overcomes a series of difficulties related to interoperability and personnel, difficulties which are generated by a lack of collaboration and communication between the project stakeholders. The present investigation finds a new solution to this problem, reducing the waste generated at the design stage of the BIM projects by implementing the A360 collaboration tool, a platform which provides a virtual centralized space that allows storing BIM files, visualizing them and making comments in real time from any device. The results show a reduction of waste that finally reduce the time for the design stage in a BIM project

  • Improved First Order Formulation for Buckling Analysis of Functionally Graded Beams

    Vallejos, Augusto; Ayala, Shammely; Arciniega, Roman (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    In this research, an improved first order formulation is presented to study the critical buckling load in functionally graded beams. The formulation has five independent variables in comparison with the Timoshenko theory that has three. The Trefftz criterion is utilized with incremental and fundamental states to define the stability analysis. Virtual work statements are derived for the finite element model where the field variables are interpolated by Lagrange polynomials. The numerical results are compared and verified with other formulations found in literature. Parametric studies are also carried out for buckling behavior due to different slenderness ratios, power-law indices and boundary conditions. Applications of the model to functionally graded materials show the validity of the present approach.

  • A comparative study of the seismic base shear force and story drift ratios using Time History and Modal Spectrum Analysis according to Peru Code E.030 and ASCE 7.16 on high-rise buildings

    Quezada Ramos, Eder Nel; Serrano Arone, Yaneth; Huaco, Guillermo (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    Since the last decade there is an important increase of high-rise buildings in Peru, especially in urban areas. Therefore, it is necessary to assess if the Peruvian Seismic Code is applicable for this type of buildings which have long natural periods as their main characteristic. The main objective of this article is to compare the results of the base shear and story drift ratios of Peruvian seismic design code E.030 with those of the ASCE 7-16 standard to the case of high-rise buildings, this due to the fact that there is limited information for tall buildings in Peru or comparison between national or international code for this type of structures. These high rise buildings have square and rectangular plan floors. Half of them have moment frames and reinforce concrete slab around the rigid core and the others have post-tensioned slab as their vertical load resisting system and central core walls with peripheral columns as the lateral force resisting system. Hence, the response spectrum analysis (RSA) is carried out for every case of the four tall buildings with different configurations using both seismic codes. Then results are compared with the linear response history analysis (LRHA) considering five Peruvian ground motions records, which were scaled to 0.45g PGA. It was verified that generally both the base shear and the interstory drifts calculated using ASCE7-16 are less than that obtained with the seismic code E.030.

  • Hazard map based on the simulation of sludge flow in a two-dimensional model, Case Quebrada Malanche-Punta Hermosa -Lima-Perú

    Garcia, Luis Jimenez; Iruri Guzman, Osnar; Hurtado, Sissi Santos (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    This research presents the numerical simulation to reproduce the transport and deposition processes of the sludge flow on March 15, 2017, strongly impacting the town of Pampapacta in Punta Hermosa-Peru.The debris flow initiation process in the basin was represented by hydrographs obtained from the estimated volumes of stormwater runoff and solid materials. The sludge flow was modeled in Flo2D to calculate hazard maps with the discharge event and others with different return periods.The numerical simulation results show acceptable results in relation to what happened. The model used to assess the hazard due to debris flow can predict and delineate, with acceptable precision, potentially hazardous areas for a landslide. The application of the proposed methodology to assess the hazard of disasters due to debris flows in basins and streams is useful to understand the extent of the impact of the mud flow during extreme weather events, as well as to develop emergency plans and formulate disaster policies.

    MacHuca, Joao Rodriguez; Pusari Quispe, Oscar; Ramirez, Gary Duran; Fernandez Diaz, Carlos (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    n this article, the geotechnical behavior of the reinforced soil is studied through additions of polypropylene fiber and recycled glass powder, this in order to obtain a homogeneously reinforced soil matrix to reduce possible structural failures, differential settlements and increase capacity bearing. The sample used was classified as a clay soil with low plasticity (CL) and with moderately expansive characteristics, based on the values of the Liquid Limit, Plastic Limit and Plasticity Index. The effect of the 1% polypropylene fiber and different amounts of recycled glass powder (0%, 4%, 5%, 6.5%), with respect to dry weight is analyzed in this soil. The purpose of varying the quantity of these materials is to find a trend of the strength parameters and obtain the optimal percentages that provides improvements in geotechnical behavior. Modified Proctor and Direct Shear tests were carried out, this latter to obtain the shear strength parameters of the mixtures and compare them with the clay soil. Finally, the optimal result for soil improvement was the mixture made by 1% polypropylene fiber and 4% glass powder, which achieved an increase of the angle of friction and cohesion.

  • Pavement management system to improve local road administration using PCI, IRI and PSI for pavement failures identification

    Quispe Sagastegui, Jose Andy; Rioja Schilder, Luisiana; Silvera, Manuel; Reyes, Jose (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    A pavement management system (PMS) is a tool that supports decision-making specialists to maintain the pavement at an optimal service level. The absence of a PMS could lead to inadequate decision-making, a disorganized road inventory, poor selection in road maintenance techniques and inefficient technical support to justify the execution of maintenance activities. For these reasons, this research proposes the application of a PMS, with the objective of improving and standardizing the processes for evaluating the condition of roads that are under the jurisdiction of low-budget government organizations, guaranteeing the selection of the most appropriate type of maintenance. As a case of study, a 1.1 km local road located in one of the districts of Lima was evaluated, which was divided into 11 sections. With this evaluation, it was obtained that 2,605.43 m2 of the total road is in poor condition, due to the presence of functional failures. For the identification of failures, the pavement condition index (PCI), the international roughness index (IRI) and the present serviceability index (PSI) were used to determine the condition, roughness and serviceability of the pavement. In conclusion, it was identified that the proposed PMS is adequately adapted to the way of working and available budget of a local administration, since if it is applied it would only spend 20.55% of the fund that would be destined to a total reconstruction of road.

  • Structural design of confined masonry buildings using artificial neural networks

    Sicha Pillaca, Juan Carlos; Molina Ramirez, Alexander; Vasquez, Victor Arana (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    The aim of this article is to use artificial neural networks (ANN) to perform the structural design of confined masonry buildings. ANN is easy to operate and allows to reduce the time and cost of seismic designs. To generate the artificial neural network, training models (traditional confined masonry designs) are used to identify the input and output parameters. From this, the final architecture and activation functions are defined for each layer of the ANN. Finally, ANN training is carried out using the backpropagation algorithm to obtain the matrix of weights and thresholds that allow the network to operate and provide preliminary structural designs with a 10% margin of error, with respect to the traditional design, in the dimensions and reinforcements of the structural elements.

  • Best HCM deterministic model calibrated for capacity analysis of basic segments of freeways in Lima

    Cubas Gonzales, Tania Lizeth; Rondon Alcedo, Rousbel Ricardo; Tarquino Torres, Fernando Mauricio (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    In traffic engineering, the assessment of capacity in basic segment of freeway is a critical factor for planning, design and operational analysis of the freeway facilities. Thereby, the Highway Capacity Manual - HCM is the main guide used in many countries of the world including Perú that contain the methodology to estimate freeway capacity in traffic studies. Nevertheless, the information of vehicular traffic used for the construction of the models proposed by the HCM, reflect the characteristics of North American features. Therefore, its application in other traffic conditions, must be backed by studies of the local conditions and calibrations of the models proposed, hereby, adjusting to each city. The objetive of this research, is calibrate and compare of the HCM 2010 and HCM 2016 models, starting off the traffic engineering study in Panamericana Sur freeway located in Lima, Perú. The report will recommended the application of a calibrated model that best represents the local Peruvian conditions. The results of this study suggest that the model of calibrated capacity HCM2016, is the best representation, with a reliability of 97%, the local behavior of the basic freeway segments in function of the speed and the flow intensity. After applying the calibrated model into basic freeway segments concessioned by Rutas de Lima SAC, it was reflected that the use of the HCM2000, employed by this Company, show flow intensities within a level of service - LOS D, while, the calibrated HCM2016 shows us that those values are found, in reality, within a level of service - LOS E.

  • Application of the scrum framework to optimize time in construction projects

    Chumpitaz, Brayan; Rubio, Junior; Rodriguez, Sandra; Hinostroza, Alexandra (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    Currently, the construction industry is characterized by a high competition between its companies. Due to this, companies must guarantee that the performance of their projects is possible by using an appropriate management system which allows an adequate planning of activities, since selecting an inadequate system can cause serious inconveniences such as having rework and increase cost and time in projects. Therefore, the construction industry is constantly searching for management models that can minimize the previously mentioned inconveniences in order to differentiate themselves and take advantage of their competitors. Precisely, the Scrum framework, conceived in the software engineering industry, is an alternative to traditional projects management, offering an exponential improvement in communication for project teams and improving the planning of activities, through an iterative framework that allows flexibility for changing requirements, reduces uncertainty and creates reliability for what was planned. Thus, this research adapts and applies the Scrum framework within a construction project, optimizing considerably the execution time.

  • Mechanical behavior direct shear a volcanic sand reinforced with polypropylene fiber and cement

    Maurizio, Cabrera Barrionuevo; Aguilar Jean Pierre, Dominguez; Lidia, Pacheco Miranda (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    This article describes consolidated Direct Cut tests not drained in the laboratory, carried out on samples of volcanic sand from Arequipa, Peru. The samples were tested for maximum dry density and optimal moisture content; Furthermore, they were reinforced with polypropylene fibers and cement. The samples were reinforced with 0.5% cement with respect to the dry weight of the sample soil and tested at 3 days. The added polypropylene fiber has dimensions of 48 mm wide with 1.2855 mm long and 0.3325 mm thick, and they were used in different percentages regarding the dry weight of the soil sample (0.25% -0.75% -1.00% -1.25%). The results of the tests indicated that the addition of polypropylene fibers together with the cement increases the resistance to cut proportionally to the amount of fiber up to 1% of fiber, this being the best result obtained, decreasing the resistance as the percentage of polypropylene fiber.

  • Competency management model to resolve conflicts with external stakeholders in construction projects

    Inga, Carol; Ochoa, Francois; Farje, Julio (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    The real estate sector in Peru has been experiencing sustained growth during the last 10 years, however, due to the constant problems that occur during the development of a project, construction as an investment is increasingly far from being the best option in the market, generally reducing its opportunity cost compared to other more specific investments. To find out what these problems are, a survey was conducted of 25 real estate project managers in Lima, establishing that one of the most recurring problems in the construction sector is conflicts with external stakeholders, mainly with the neighbors surrounding the work, and how these tend to worsen due to inadequate management by project team members who are assigned to resolve the conflict situation.In this sense, this study focuses on knowing the competences that workers have within an organization and what they need to efficiently manage problems with neighbors, and then propose a management model by competences focused on improving the performance of workers of a construction company developing a set of strategies and activities that increase their competitiveness in the face of confrontation between both parts. The results obtained from a real estate construction project indicated that the proposed model manages to reduce or prevent conflicts with neighboring homes, improving the achievement indicators of the aforementioned project under analysis.

  • Seismic Retrofit in Hospitals using Fluid Viscous Dampers

    Caceres-Perez, Gladys; Pichihua-Alata, Natali; Huaco-Cardenas, Guillermo (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    The addition of fluid viscous dampers to structures increases damping and reduce the lateral displacements due large earthquake loads, being an effective technique for seismic control of responses specially by severe earthquakes events and structures at high seismic hazard zone, safeguarding them from possible collapse. The objective of this research is to compare the structural performance of essential structures of confined masonry older than 50 years, asbuilt and retrofitted with viscous dampers. Additionally, the structure is analyzed with a traditional reinforcement technique such as reinforced concrete walls, in order to evaluate the feasibility of the first proposal. It was found that including dampers the drifts are reduced from 0.6% to its half, better performance that implementing concrete walls with 0.45% drift response. Besides stresses levels at masonry walls have been reduced better than retrofit building new concrete walls. It is shown the feasibility of the proposal in structural responses using fluid viscous dampers,

  • Analysis of the influence of the characteristics of the environment on the time of pedestrian transhipment in a multimodal transport using the social force model

    Asenjo, Christian; Tocas, Frank; Silvera, Manuel; Campos, Fernando (Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
    The Highway Capacity Manual (HCM-2010) indicates in Volume III (Chapter 17) how the characteristics of the environment can represent obstacles that influence the determination of the average pedestrian space. However, the HCM does not specifically analyse in detail how these obstacles affect specifically the path, speed and average walking time of pedestrian. This article performs a comparative analysis between two microsimulations models where it is evidence how by not considering the characteristics of the fixed and mobile environment, the transhipment time and the speed of people are modified. As a case study, the obstacles present in the environment during the transhipment carried out by users in an integrated multimodal transport system in the city of Lima are identified. The comparative analysis between both cases shows the influence of the characteristics of the environment of the transhipment and variation in the average speed of the pedestrians. The proposed study methodology is calibrated and validated by microsimulations in Vissim Software. The comparative analysis reflects an increase in the transhipment time of 19.4% and a decrease in the average speed of the pedestrians by 14.8 %, reflecting in the microsimulation model values near to the real behaviour of pedestrians.
