Environmental intelligence aims to improve the decision-making process for high social and environmental value ecosystems. To this end, data are collected using different sensors allow monitoring of variables interest. Typically, these ecosystems cover a large geographical area, with spots low or no connectivity, preventing their in real time. In work, we propose AlLoRa (Advanced Layer LoRa), modular, low-power, long-range communication protocol based on LoRa, that allows remote natural...
There is a high rate of co-morbidity between binge-eating and binge-drinking behaviors, suggesting common neuropathology. Recently, phosphodiesterase 4B (PDE4B) was identified as pleiotropic gene associated with comorbid alcohol use disorder (AUD) anorexia nervosa in genome-wide association study, implicating PDE4B potential contributor to shared genetic risk these disorders. To address this possibility, we developed novel mouse model co-morbid -drinking C57BL/6NJ mice which underwent 10...
Nowadays, the overwhelming amount of data generated on Internet have boosted development new solutions to process time windows closer real time. Such are known as Distributed Stream Processing Engines (DSPEs). DSPEs were specially designed streams over cluster infrastructure, however great massification mobile devices opens opportunities source in order reduce latency and traffic network. In this paper we propose Symbiosis, an architecture oriented clients such tablets smartphones. Symbiosis...
Collecting and disseminating critical information in the direct aftermath of a disaster is very challenging: communication infrastructures are likely to fail, mobility becomes severely limited. Current solutions rely on traditional delay tolerant network (DTN) protocols amongst mobile devices gather relay vital data, but they induce an irreconcilable trade-off between delivery ratios cost-efficiency. This paper proposes combine every device: behavior device determines routing protocol that...
Every year, thousands of disasters impact the world, generating substantial loss in terms lives and public infrastructure. The recovery phase requires money investment for governments, order to rebuild affected region. To minimize effects a disaster, applications supporting decision-making through real-time analytics must be fast accurate. These tools may supported by stream processing systems that enable structure-less data; however, their use configuration require expert programming...
Traditional DHT structures provide very poor support for range queries, since uniform hashing destroys data locality. Several schemes have been proposed to overcome this issue, but they fail combine load balancing, low message overhead, and latency in search operations. In article we present DRing, an efficient layered solution that directly supports queries over a ring-like structure. We improve balancing by using only the nodes store data, updating neighbour information through optimistic...

Every year, hundreds of natural phenomena hit the world, unleashing major disasters and compromising welfare millions people public infrastructure. On a planet made up over 70% water, tsunamis are latent risk that threatens civilians all world. Hopefully, technological advances have provided development monitoring systems enable predicting this kind evacuating high flooding zones. Nowadays, mobile communication in post disaster scenario is critical to support tasks. However, developing...
This paper addresses the problem of predicting tertiary structure a given amino acid sequence, which has been reported as NP-Complete class problem. We evaluate how combination two weighted energy functions, Talaris and SASA from Rosetta software suite, can improve, in reasonable computational time, quality solutions distributed implementation knowledge-based memetic algorithm for protein prediction The proposal is evaluated terms accuracy biological significance predicted structures....
In the aftermath of major disasters such as earthquakes, locating individuals is crucial for passing on vital information, example warnings and safety announcements. However, large scale cause extensive damage to network infrastructures a generalized loss communications in chaos that ensues. This position paper presents preliminary study geolocation service relies inter-device connections: mobile devices exchange positions previously encountered when they come into contact. Every device thus...
On post disaster scenarios, communication infrastructure can be seriously compromised, generating intermittent or null Internet access. Delay Tolerant Networks (DTNs) are a promising mechanism able to deal with connection disruptions enabling for affected people. DTNs forward messages through untrusted devices, which have better probability reach destination. However, they susceptible attacks where participants forge their metrics in order them appear as alternative route messages, thus most...
