Mobile technologies to enable users' informed decisions
No full textThe significant wide impact of mobile technologies (e.g., smartphones, tablets) and the difficulty of mastering their complexity (due to factors like constant emergence and evolution) pose new challenges to many (if not all) software engineering disciplines. We particularly see these challenges when thinking of average citizens that carry out their daily activities in smart environments where mobile technologies and sensors installed provide many potential advantages to support them. Applications that could enable informed decision-making are currently beyond what software developers can provide. This position paper discusses challenges, and highlights current approaches available in order to support decision-making for thoughtful living. We present an initial version of a comprehensive framework to overcome the challenges identified and analyse which software engineering research lines may help to implement it. A motivating scenario is used to conduct the discussion
Foundations of ANTCYCLE: self-synchronized duty-cycling in mobile sensor networks
No full textAnts are generally believed to follow an intensive work routine. Numerous tales and fables refer to ants as conscientious workers. Nevertheless, biologists have discovered that ants also rest for extended periods of time. This does not only hold for individual ants. Interestingly, ant colonies exhibit synchronized activity phases that result from self-organization. In this work, self-synchronization in ant colonies is taken as the inspiring source for a new mechanism of self-synchronized duty-cycling in mobile sensor networks. Hereby, we assume that sensor nodes are equipped with energy harvesting capabilities such as, for example, solar cells. We show that the proposed self-synchronization mechanism can be made adaptive depending on variable energy resources. The main objective of
this paper is to study and explore the swarm intelligence foundations of self-synchronized dutycycling. With this purpose in mind, physical constraints such as packet collisions and packet loss are
generally not considered.Peer ReviewedPostprint (published version
A protocol for self-synchronized duty-cycling in sensor networks: Generic implementation in Wiselib
No full textIn this work we present a protocol for self-synchronized duty-cycling in wireless sensor networks with energy harvesting capabilities. The protocol is implemented in Wiselib, a library of generic algorithms for sensor networks. Simulations are conducted with the sensor network simulator Shawn. They are based on the specifications of real hardware known as iSense sensor nodes.
The experimental results show that the proposed mechanism is able to adapt to changing energy availabilities. Moreover, it is shown that the system is very robust against packet loss.Peer ReviewedPostprint (published version
Epidemiología del ancylostoma caninum y su impacto en la salud pública en Colombia
No full textAncylostoma caninum es uno de los endoparásitos más frecuentes en la clínica de pequeños animales, por esto es de vital importancia aprender a reconocer su ecología y dar a conocer su importancia en la salud pública. Existen múltiples reportes de caso a nivel mundial sobre larva migrans cutánea, esta es una infección parasitaria común en regiones tropicales y representa una zoonosis. Esta condición es causada por la penetración y movimiento a través de la piel de nematodos como Ancylostoma caninum, Ancylostoma braziliense, Ancylostoma duodenale y Ancylostoma ceylanicum. En Colombia se han reportado casos de prevalencia de Ancylostoma caninum en ciudades como Medellín 26%, Tunja 22.6%, Cundinamarca 66.52%, Villavicencio 22%, Florencia 44.16%. Esto representa un problema en la salud pública asociado a las malas prácticas de higiene, el manejo inadecuado de las heces en ambientes públicos y la sobrepoblación de perros en condición de calle.Ancylostoma caninum is one of the most frequent endoparasites in the small animal clinic, which is why it is vitally important to learn to recognize its ecology and make its importance in public health known. There are multiple case reports worldwide on cutaneous larva migrans, this is a common parasitic infection in tropical regions and represents a zoonosis. This condition is caused by the penetration and movement through the skin of nematodes such as Ancylostoma caninum, Ancylostoma braziliense, Ancylostoma duodenale and Ancylostoma ceylanicum. In Colombia, cases of prevalence of Ancylostoma caninum have been reported in cities such as Medellín 26%, Tunja 22.6%, Cundinamarca 66.52%, Villavicencio 22%, Florencia 44.16%. This represents a public health problem associated with poor hygiene practices, inadequate management of feces in public environments and the overpopulation of street dogs.Resumen. --
