1. Assessment of Total Attenuation and Adaptive Scheme for Quality of Service Enhancement in Tropical Weather for Satellite Networks and 5G Applications in Nigeria
Abstract The dynamic weather condition is a major concern for optimum channel utilization in recent times, especially at higher frequencies with larger bandwidth for 5G applications. Over the years, rain-induced attenuation among the hydrometeors has been linked as the major cause of signal impairment especially at the frequency, f ≥ 10 GHz. However, when

4. Algoritmo de escalonamento DRR com quantum adaptativo para o tráfego downlink de redes IEEE 802.16j / DRR adaptive quantum scheduling algorithm for downlink traffic of IEEE 802.16j networks
IEEE 802.16j networks provide, through the Relay Station (RS), improvements with regard to previous specifications of WiMAX in terms of increased coverage area, reduction of deployment costs due to low cost of RS compared to a Base Station (BS) and system average throughput increase. Its main purpose is to meet demands for wireless broadband access at lower

5. Uma abordagem estocástica baseada em aprendizagem por reforço para modelagem automática e dinâmica de estilos de aprendizagem de estudantes em sistemas adaptativos e inteligentes para educação a distância
An important feature in Distance Education is the personal and intelligent assistance, in which an important aspect is that students may have quite different profiles. Thus, a course designed for a particular student may not be suitable for other students. Because of this, a challenge in research is the development of advanced educational applications that p

6. Desenvolvimento de modelo multidimensional de predição de peptídeos antimicrobianos utilizando um sistema de inferência neuro-fuzzy adaptativo (ANFIS)
Antimicrobial peptides (AMPs) are defense molecules widely distributed and represent a promising alternative for solving the problem of antibiotic resistance. Nevertheless, the experimental time needed to screen putative AMPs makes computational simulations based on peptide sequence analysis and/or molecular modeling extremely attractive. Artificial intellig

7. A FRAMEWORK FOR DEVELOPING SELF-ADAPTIVE AGENTS IN MOBILE DEVICES / UM FRAMEWORK PARA DESENVOLVIMENTO DE AGENTES AUTOADAPTATIVOS EM DISPOSITIVOS MÓVEIS
Technological progress in mobile computing and the Internet promotes an achievement of the futuristic vision in which users have access to data and services anytime and anywhere. However, this vision realization brings important issues to application development, because more attention is required to the communication between mobile devices and web services,

8. Green-Markov models - new optimization strategies: a case study for user allocation in co-channel macro/femto networks
The femtocell concept aims to combine fixed-line broadband access with mobile telephony using the deployment of low-cost, low-power third and fourth generation base stations in the subscribers' homes. While the self-configuration of femtocells is a plus, it can limit the quality of service (QoS) for the users and reduce the efficiency of the network, based o

9. Identificação e caracterização de genes codificantes de proteínas ricas em glicina ligantes de RNA em soja (Glycine max (L.) Merril)
Molecular information on plant developmental process, as well as detailed knowledge of the interaction between stress conditions and plant response to environmental factors are essential for understanding the adaptive response. Glycine-Rich Proteins (GRP) have the amino acid glycine well represented in their primary structure. The genes encoding GRPs are dev

10. ROBUST VARIABLE STRUCTURE MODEL REFERENCE ADAPTIVE CONTROL APPLIED TO ACTIVE POWER FILTERS / CONTROLE ADAPTATIVO ROBUSTO DE ESTRUTURA VARIÁVEL POR MODELO DE REFERÊNCIA APLICADO A FILTROS ATIVOS DE POTÊNCIA
This works presents a Robust Variable Structure Model Reference Adaptive Control scheme denoted VSRMRAC. In this adaptive control strategy, each parameter of the control law is obtained by the sum of two other adaptive terms. One of them is associated with the RMRAC algorithm, while the other is composed of an adaptive gain rated by an approximated sign func

11. ASSOCIAÇÃO DO CONTEXTO DE INTERESS DO USUÁRIO ÀS ATIVIDADES CLÍNICAS NA ARQUITETURA CLINICSPACE / Association of the Context of Users Interesting to Clinical Activity in Architecture ClinicSpace
Currently, we seek to make the systems more oriented to end-user, reducing the distance between how the user carries out its activities and modeling these in Information Systems in Health, the doctor providing adaptive and personalized forms of use, configuration and control system, based on historical usage, or a profile. To meet these requirements, the pro

Estresse e modos de andar a vida: subsídios de Georges Canguilhem para uma etnoepidemiologia da Síndrome Geral da Adaptação na cidade de São Paulo / Stress and ways of walking life: subsidies of Georges Georges Canguilhem for an ethnoepidemiology of the General Adaptation Syndrome in the city of Sao Paulo.
This study investigated the perception that the residents of a condominium in the city of Sao Paulo have about their stress and life conditions, with the goal of establishing a critical reflection based on a ethnoepidemiologic proposal. We employed descriptive research on residential condominium called "Projeto Viver Celso Garcia CPV in the district of Belen
