IPV6 Connectivity and Management Emulation for REUNA, the Chilean Advanced Network 智利先进网络REUNA的IPV6连接和管理仿真
J. Castillo-Velazquez, Victor Raul Cobos Panduro, William Rogelio Marchand Niño
RAAP is the advanced network for Peru, but the lack of use of it, pushed to RAAP to be out of Latin America and the world’s advanced networks in 2018. So, to promote inside Peruvian universities the importance of this kind of research networks, REUNA, the advanced network of Chile was analyzed. So, connectivity and management for REUNA’s backbone network were emulated using IPV6 as commercial ISP companies do. Results show emulator capabilities and limitations when approaching to real backbone’s infrastructure. This work is under a tech transfer collaboration project.
RAAP是秘鲁的先进网络,但由于缺乏使用,导致RAAP在2018年被排除在拉丁美洲和世界先进网络之外。因此,为了在秘鲁大学内部推广这种研究网络的重要性,分析了智利先进网络REUNA。因此,REUNA骨干网的连接和管理使用IPV6进行模拟,就像商业ISP公司所做的那样。结果显示了仿真器在接近真实骨干网基础设施时的能力和局限性。这项工作是在技术转让合作项目下进行的。

A Novel Architecture for Implementation of Quasi Delay Insensitive Finite State Machines 一种新的准延迟不敏感有限状态机实现结构
D. L. Oliveira, Orlando Verducci, Vitor L. V. Torres, O. Saotome, R. Moreno, João B. Brandolin
Due to the increasing demand for mobile devices, the search for ultra-low-power projects is becoming a priority. One technique that allows a strong reduction of circuits dissipated power is the sub-threshold voltage operation, but it leads to some drawbacks. The QDI (Quasi Delay Insensitive) asynchronous circuits class shows to be an interesting solution to these problems, when compared to synchronous circuits and in CMOS-UDSM (Ultra Deep Sub-Micron) technology. Asynchronous finite state machines (AFSMs) are important components in an asynchronous system. This paper proposes a new architecture for QDI AFSMs described in Extended Burst-Mode specification, implemented in the dual-rail style using basic gates and memory based on RS latches. The resulting XBM_AFSMs are QDI, so they can operate in sub-threshold voltage. The architecture is presented through the case study and the obtained QDI_XBM_AFSM presents for three benchmarks an average reduction of 24.4%, and 48.3%, 49.6% and 49.2% respectively, latency time, number of LUTs, dynamic power and static power, when compared with four QDI controllers of the literature.
由于对移动设备的需求不断增加,寻找超低功耗项目正成为一个优先事项。一种可以大大降低电路耗散功率的技术是亚阈值电压操作,但它会导致一些缺点。与同步电路和CMOS-UDSM(超深亚微米)技术相比,QDI(准延迟不敏感)异步电路类显示出这些问题的有趣解决方案。异步有限状态机(AFSMs)是异步系统的重要组成部分。本文提出了一种扩展突发模式规范中描述的QDI AFSMs的新架构,该架构采用基于RS锁存器的基本门和存储器的双轨风格实现。得到的xbm_afsm是QDI,因此它们可以在亚阈值电压下工作。通过案例研究给出了该体系结构,得到的QDI_XBM_AFSM与文献中的四种QDI控制器相比,在三个基准测试中,延迟时间、lut数量、动态功率和静态功率分别平均降低了24.4%、48.3%、49.6%和49.2%。

Dennis Núñez
This paper describes an implementation of a novel real-time recognition system which is capable to identify important information from a single user such as gender, age, emotions and hand gestures. The key of this recognition system is the classification process. This is carried out by using several convolutional neural networks that were designed to achieve a high accuracy rate and acceptable response time making use of low computational resources. As a result, this recognition system could be useful in numerous applications like human-computer interaction, person identification, security control and others.

Scheme of Self-Evaluation Applied to Engineering Programs Previous to Accreditation Processes in Emergent Latin American Universities 在新兴的拉丁美洲大学认证程序之前应用于工程项目的自我评估方案
H. Nieto-Chaupis
We focus on the processes of self-evaluation in up to three engineering programs of a young private Peruvian university locate in the edge of Lima city. Based on the fact that the university system runs equally for a important fraction of Latin American universities, we have proposed a possible way to carry out a self-evaluation procedure based entirely in the majors of the programs by assuming that all of them are expecting a full evaluation towards to the program accreditation. From our scheme, the accreditation might require to implement solid scenarios where student carries out tasks of research inside of the capstone project, fact that would give capabilities to the future bachelor not only in the employability sectors but also in territories of purely academic activities.

J. Celis, Rodrillo Llanos, Sergio Castro, S. Sepulveda, Byron Medina, D. Guevara, Luis Camargo, J. Gómez
This paper presents a voice processing for a domotic application in the development of the Internet of things. The recognition was based on a computational intelligence implemented in the Raspberry Pi B + embedded system, which is controlled by voice using the "Comand and Control" method from a mobile application created in Android Studio, which in addition to receiving and sending the commands also allow to monitor the real-time states of the connected devices through a database. We developed and implemented an Acoustic Model and a Language Model for the people who live in the Norte de Santander region. The voice processing integrates three devices that allow controlling the lighting of the house, in addition to the measurement of temperature, humidity and presence, applying bidirectional radiofrequency communication with the Raspberry Pi. The evaluation of the system consisted of a point-to-point comparison with a licensed system considering the characteristics required by the user and obtaining a reduction in costs of 57 % including labor and a commercial profit of 50 %.

Marcelo Vilela, G. Siles
As the use of high frequency bands, is becoming more and more attractive for using on future commercial and military satellite communications, the effects of atmospheric water vapor and oxygen are more relevant. In order to reduce gaseous absorption effects, high altitude sites can be good candidates for deploying high capacity ground stations at these frequencies. This paper explores the use of radiosoundings carried out in La Paz, Bolivia, at 4061 m.a.s.l., extracted from the Integrated Global Radiosonde Archive (IGRA), in order to estimate gaseous attenuation based on the last version of the ITU-R Recommendation P.676. Time series of gaseous attenuation at Ka, Q, V and W band are presented.

Cognitive technology model to enhanced academic support services with chatbots 认知技术模型与聊天机器人增强学术支持服务
Marilyn Choque-Díaz, Jimmy Armas-Aguirre, P. Shiguihara-Juárez
In this paper, we propose a cognitive technology model to enhance academic support services with chatbots. The difference between the conventional models and the model proposed in this paper lies in adding Customer Experience patterns to the chatbot. This could substantially improve the interaction between the chatbot and the student in the institution. Our proposed model also emphasizes the use of best practices for real-time data processing. The model consists of five phases: 1. Capture; 2. Understanding Natural Language; 3. Dialog management; 4. Generated responses; 5. Consumption. We evaluate our cognitive technology model with undergraduate students at Universidad Peruana de Ciencias Aplicadas. The preliminary results showed a reduction of more than 99.9% in the average response time expected per query and an acceptance level of 80% within the target population.

Walther Palomino, Giorgio Morales, Samuel G. Huamán, J. Telles
Providing timely information through remote sensing tools to the farmers and to the National Institute of Agrarian Innovation (INIA) is important to manage the production of yellow corn crops (Zea Mays) in the region of Lambayeque, Peru. This paper addresses three objectives by providing information in different levels: First, provide information about the Normalized Difference Vegetation Index (NDVI) from crops in their different stages during their lifecycle; secondly, provide georeferenced soil analysis information organized by parcels and, finally, provide information about evapotranspiration of each parcel calculated using weather station sensors, soil type, land uses and georefer-enced NDVI masks. All this information is provided through a Geographic Information System called Remote Sensing Platform for Agricultural Purposes (PETEFA), which is based on open source tools. In short, PETEFA is a monitoring tool that provides information through a computer or mobile device to the farmers or the INIA.
通过遥感工具向农民和国家农业创新研究所(INIA)提供及时的信息对于管理秘鲁Lambayeque地区的黄色玉米作物(Zea Mays)的生产非常重要。本文通过提供不同层次的信息来实现三个目标:第一,提供作物在其生命周期不同阶段的归一化植被指数(NDVI)信息;其次,提供按地块组织的地理参考土壤分析信息;最后,提供利用气象站传感器、土壤类型、土地利用和地理参考NDVI掩模计算的每个地块的蒸散发信息。所有这些信息都是通过一个名为农业遥感平台(PETEFA)的地理信息系统提供的,该系统基于开源工具。简而言之,PETEFA是一种监测工具,通过计算机或移动设备向农民或INIA提供信息。

REAL-TIME CORNER DETECTION ON MOBILE PLATFORMS USING CUDA 基于cuda的移动平台实时角点检测
Hector Chahuara, P. Rodríguez
Corner detection is a widespread task in many high-end applications such as autonomous driving systems and augmented reality. However, corner detection algorithms are computationally expensive and thus are not suitable for real-time applications on mobile devices. The Tegra device series, which incorporates Graphics Processing Units (GPUs), is aimed at mobile computing and accelerates computations for mobile applications. In this paper, a GPU realization of a color-adapted Harris corner detector with high-level extensions is proposed and tested in Tegra-based platforms Jetson TK1, TX1 and TX2. The proposed realization achieves good detection quality, real-time processing for grayscale and color images up to full HD resolution (1080p) in all platforms and frame rates of 14.02 ~ 18.71, 27.76 ~ 39.44 and 34.82 ~ 51.32 for images of resolution 4K UHD (2160p) in Jetson TK1, TX1 and TX2 respectively.

Implementation of a mechanical-electronic system for children from 7 to 11 years old with Duchenne muscular dystrophy 为患有杜氏肌营养不良症的7至11岁儿童实施机械-电子系统
Martha Medina-De-La-Cruz, Anderson Mujaico-Mariano, Gabriel Tirado-Mendoza
Duchenne muscular dystrophy is a neuromuscular disease that affects the infant stage and causes progressive muscle weakness, and during the time loses the motor ability to walk. Unfortunately, in Peru, cases of children with this disease have increased. Therefore, the idea is to implement a mechanical-electronic system to assist in the movement or mobility of patients. In the present research work, shows the development of a system with four degrees of freedom, using reducing motors that are manipulated by two joystick modules, controlled by the platform Arduino and the shield motor driver L293D. After the use of the system in the lower extremities of the patient based on a pre-training, it is possible to demonstrate that the system works in real time, besides allowing a exacts movements of the lower extremities.
杜氏肌营养不良症是一种影响婴儿阶段的神经肌肉疾病,导致进行性肌肉无力,并在此期间失去运动能力。不幸的是,在秘鲁,患有这种疾病的儿童病例有所增加。因此,我们的想法是实现一个机械电子系统来帮助病人的运动或移动。在目前的研究工作中,展示了一个四自由度系统的开发,使用减速电机由两个操纵杆模块操纵,由平台Arduino和屏蔽电机驱动器L293D控制。在基于预训练的患者下肢使用该系统后,除了允许下肢的精确运动外,还可以证明该系统是实时工作的。
