Unified radio and network control across heterogeneous hardware platforms

Experimentation is an important step in the investigation of techniques for handling spectrum scarcity or the development of new waveforms in future wireless networks. However, it is impractical and not cost effective to construct custom platforms for each future network scenario to be investigated. This problem is addressed by defining Unified Programming Interfaces that allow common access to several platforms for experimentation-based prototyping, research, and development purposes. The design of these interfaces is driven by a diverse set of scenarios that capture the functionality relevant to future network implementations while trying to keep them as generic as possible. Herein, the definition of this set of scenarios is presented as well as the architecture for supporting experimentation-based wireless research over multiple hardware platforms. The proposed architecture for experimentation incorporates both local and global unified interfaces to control any aspect of a wireless system while being completely agnostic to the actual technology incorporated. Control is feasible from the low-level features of individual radios to the entire network stack, including hierarchical control combinations. A testbed to enable the use of the above architecture is utilized that uses a backbone network in order to be able to extract measurements and observe the overall behaviour of the system under test without imposing further communication overhead to the actual experiment. Based on the aforementioned architecture, a system is proposed that is able to support the advancement of intelligent techniques for future networks through experimentation while decoupling promising algorithms and techniques from the capabilities of a specific hardware platform

Correlations between the performance of older adults in conditional discrimination training and in a screening test for Alzheimer’s Disease

The prevalence of neurocognitive disorders has been rising and Alzheimer's Disease (AD) is the most common cause. Studies on conditional discrimination have contributed to understand the variables associated with the cognitive function. However, the relationship of such studies with cognitive impairment in older adults remains under-explored. This research aims to compare the performances of older adults during tasks involving conditional discrimination training with their performances on Addenbroke's Cognitive Examination, a widely used screening test for cognitive impairments. The sample was composed of 45 older adults. The participants performed a computerized task consisting on establishing arbitrary conditional relations between three pairs of stimuli. Addenbrooke's Cognitive Examination was administered to assess the cognitive performance. The analysis revealed a positive correlation between the performance in conditional discrimination and in the cognitive assessment. This correlation was observed only among participants who did not reported having AD in use of anti-cholinesterase drugs (30 participants). These findings demonstrate a direct relationship between learning difficulties, when it comes to learning arbitrary conditional relations, and the occurrence of cognitive decline. Therefore, the administration of the conditional relations tasks could be useful for distinguishing older adults with and without AD. Keywords: Conditional discrimination; neuropsychological tests; elderly; Alzheimer's Disease

"Антропологизация" как фактор проблематизации в познании

Рассматривается процесс антропологизации познания через способы проблематизации знания. Делается вывод, что онтологический плюрализм требует соответствующего способа совмещения разных начал, проблематизация которых осуществляется на основе способностей человека познавать мир. Принцип дополнительности и антропный принцип выражают указанные особенности проблематизации знаний человека

Diagnóstico de gestação de fêmeas nelore de diferentes categorias criadas extensivamente no ecótono Cerrado/Pantanal, Aquidauana/MS.

Informações de diagnóstico de gestação considerando diferentes categorias de fêmeas Nelores tornam-se necessárias para elaboração de estratégias de manejos diferenciada a cada categoria, com objetivo de suprir as exigências necessárias para aumentar o desempenho do rebanho. Objetivou-se realizar um diagnóstico de gestação de fêmeas Nelore de diferentes categorias criadas extensivamente no ecótono Cerrado/Pantanal, Aquidauana/MS. Para análise do diagnóstico de gestação, foram utilizadas informações coletadas, entre os anos de 2003 a 2012, de 5.433 fêmeas Nelores, criadas em sistemas de manejo extensivo. Observou-se que tanto as vacas adultas como as novilhas apresentaram melhor eficiência reprodutiva com relação ao diagnostico de gestação, quando com parado as vacas primíparas, sendo em ambos os casos as diferenças significativas (P<0,01). Maiores coeficiente de variação (CV) foram verificados para a categoria de vacas primíparas (CV = 5,70%), o que indica oscilações na taxa de fêmeas prenhes durante os anos de análise. As vacas adultas e novilhas apresentam taxas de prenhes superiores ao esperado, sendo essa diferença de 8,39% e 6,46% respectivamente, ao passo que as vacas primiparas apresentaram 61,90% a menos que o esperado. Conclui-se que diagnóstico de gestação foi uma prática de manejo eficiente para identificar o manejo adequado para cada categoria. Vacas primíparas apresentaram como a categoria mais exigente e responsável pela diminuição da taxa de prenhez do rebanho

Discovering the spatial coverage of the documents through the SpatialCIM Methodology.

The main focus of this paper is to present the SpatialCIM methodology to identify the spatial coverage of the documents in the Brazilian geographic area. This methodology uses a linguistic tool to assist in the entity recognition process. The linguistic tool classifies the recognized entities as person, organization, time and localization, among others. The localization entities are checked using a geographic information system (GIS) in order to extract the Brazilian entity geographic paths. If there are multiple geographic paths for a single entity, the disambiguation process is carried out. This process attempts to locate the best geographic path for an entity considering all the geographic entities in the text. Another important objective of this paper is to show that the disambiguation process improves the geographic classification of the documents considering the obtained geographic paths. The validation process considers a set of news previously labeled by an expert and compared with the results of the disambiguated and non-disambiguated geographic paths. The results showed that the disambiguation process improves the classification compared with the classification without disambiguation. Keywords: Ambiguity problem resolution, spatial coverage identification, toponym resolution
