Nowadays CLARA (Latin Americas Consortium for Advanced Networks) is partially stagnated with no grow since last update in 2013, with this review we hope in a near future offer a new proposal for updating and reactivation of advanced networks in Latin America. A step by step simulation was developed in order to get first approach to how CLARA works;...

The National Research and Education Networks or Advanced Networks implemented in all countries in the world are the alternative Internet to the commercial Internet which was developed for education and experimental purposes beginning with the Internet 2. Our interest is to study the CANARIE topology after 27 years of the foundation of the pan-Canad...

The application of chip implants to animals is very common in many countries. For example, in pets to help to identify and link them with their owners, or to help farmers to control their cattle and provide traceability of them during their commercialization. On the other hand, chips implants in humans have been circled by resistance; however since...

In recent years, biometric systems have been used to provide access control security, to help identify and recognize people. However, today due to the advance of the pandemic some of the biometric systems are considered as sources of transmission and contagion of COVID-19. This situation motivates us to the development of a facial recognition acces...

Advanced Networks have been studied through emulation testing connectivity and management under IPv4 and IPv6 using their corresponding routing and management protocols such as ISP companies do for backbone infrastructure. In this work, given four different and complex backbone advanced networks in different regions in the world, four different kin...

In this work, a traditional network or a hardware defined network is compared to a software defined network given a specific backbone topology. Authors choose REUNA, the advanced network for Chile, a dynamic backbone topology which has evolved respect to backbone routers and bandwidth. GNS3 is used to emulate REUNA backbone topology as a traditiona...

AFRICACONNECT is composed of three advanced networks UBUNTUNET, WACREN and ASREN, which connect the national research and education networks in 29 countries in Africa. Each backbone infrastructure has evolved over time and has been updated, with bandwidth and backbone router capability being added. IPv6 connectivity and management assessment emulat...

Advanced networks born after the development of the commercial Internet, those networks are the infrastructure of the national research and education networks around the world, acting as Internet version 2 for each country. The backbone internet infrastructure is so expensive that just a few internet service providers in a country can invest and de...

Nowadays Perú has not a NREN (National Research and Education Network) also named advanced network. In past Perú had one named RAAP, connected to CLARA (Latin American Consortium for Advanced Networks) since 2005 but till 2017 when it was disconected from CLARA and therefore from the world. In this work authors proposed a new backbone topology for...

UTILCON es un sistema de gestión de conferencias (CMS) en línea gratuito en español, desarrollado y respaldado por ADVNETLAB en la Universidad Autónoma de la Ciudad de México (UACM). En 2018, UTILCON funciona como versión beta, es muy fácil de usar para los autores y los árbitros que tienen sus primeros enfoques en conferencias nacionales en españo...

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 n...

Mobile workflow execution is gaining importance as traditional process execution systems are employed in many new scenarios such as mobile networks or the Internet of Things. Unfortunately, in these solutions, security is still based on control loops or computer science techniques which have not evolved as fast as current mobile systems and applica...

ADVNETLAB Methodology for thesis advisory in science and engineering for ICT was designed in 2013, implemented, and tested as an innovative methodology for high performance projects. This projects-based learning methodology was based on project management and quality methodologies applied to industry, consulting, and academic projects for more than...

The backbone of INTERNET 2 has been evolving since 1996 when it was founded. In 2008, a scalable design included three advanced layer services, which where updated in 2014 with 100 Gbps links. In 2016 INTERNET2 had its last update, so a detailed simulation and emulation were developed for connectivity and management for each backbone(´s) node, spec...

CLARAs backbone (Latin Americas Consortium for Advanced Networks) was stagnated in 2013 with just one 10 Gbps links and ten backbone nodes. In 2016 CLARAs backbone was updated having nine 10 Gbps links ant thirteen backbone nodes. Following CLARA s backbone evolution, simulation as first approach and emulation as a second approach were developed fo...

Mobile workflow execution is gaining importance as the interaction among mobile devices, IoT and cloud becomes ubiquitous. Unfortunately, the instantiation of mobile security controls has not evolved as fast as current mobile applications and services, in part because of the tight coupling between these controls and the mobile workflow's execution...

Los data centers han pasado de la infraestructura construida en grandes áreas como verdaderos bunkers. Las empresas chinas fueron las primeras en proponer unidades mínimas de data centers colocados en contenedores. También la comunidad ha hido proponiendo el enfriamiento sumergiendo capsulas de data cetenrs en cuerpos de agua. Sin embargo, en esta...

After applying several projects management and quality methodologies to industry, consulting and academic projects of different complexity levels for several years, a methodology for thesis advisory was designed and implemented using an approach from projects management, in order to increase the quantity and quality of terminal efficiency when faci...

Dijkstra and Bellman-Ford routing algorithms were applied to the CUDI (Consorcio Universitario para el Desarrollo de Internet 2-University Consortium for the Development of Internet 2) advanced network backbone infrastructure.

Palabras clave: contaminación, agua, pilas. RESUMEN Los fabricantes de pilas afirman que las pilas como residuos son inocuas al medio ambiente, sin embargo en este trabajo demostramos que no es así. Se evalúa cómo cambia el pH del agua de acuerdo al grado de exposición que tenga con los electrodos y electrolitos de pilas alcalinas duracell y tectro...

Standard IEEE 1625 for .....

Todo equipo electrónico portátil, como teléfonos celulares e inalámbricos, radios de dos vías, laptops, PDAs, etc., toma su energía de pilas y baterías. Al "agotarse" estas fuentes energéticas se desechan y se convierten en residuos peligrosos (RP), que pueden contaminar aire, cuerpos de agua y suelo. Toxicología: Diez componentes de las pilas af...

The preparation of the solid solution Bi4Ti3-XCuXO12 (0.005 < × < 0.25) has been recently reported. In this work we present the results of studies of the thermal properties done by differential scanning calorimetry (DSC) from room temperature up to 550° C.
