uRT51: An Embedded Real-Time processor implemented on FPGA devices
In this paper we describe and evaluate the main features of the uRT51 processor. The uRT51 processor was designed for embedded realtime control applications. It is a processor architecture that incorporates the specific functions of a real-time system in hardware. It was described using synthesizable VHDL and it was implemented on FPGA devices. We describe how the uRT51 processor supports time, events, task and priorities. The performance of the uRT51 processor is evaluated using a control application as a case study. The experiments show that the uRT51 processor scheduling features outperform the ones obtained using a traditional RTOS-based real-time system.Fil: Cayssials, Ricardo Luis.

Alter ego, state of the art on user profiling: an overview of the most relevant organisational and behavioural aspects regarding User Profiling.
This report gives an overview of the most relevant organisational and\ud
behavioural aspects regarding user profiling. It discusses not only the\ud
most important aims of user profiling from both an organisationâs as\ud
well as a userâs perspective, it will also discuss organisational motives\ud
and barriers for user profiling and the most important conditions for\ud
the success of user profiling. Finally recommendations are made and\ud
suggestions for further research are given
Modes and models in disorders of consciousness science
The clinical assessment of non-communicative brain damaged patients is extremely difficult and there is a need for paraclinical diagnostic markers of the level of consciousness. In the last few years, progress within neuroimaging has led to a growing body of studies investigating vegetative state and minimally conscious state patients, which can be classified in two main approaches. Active neuroimaging paradigms search for a response to command without requiring a motor response. Passive neuroimaging paradigms investigate spontaneous brain activity and brain responses to external stimuli and aim at identifying neural correlates of consciousness. Other passive paradigms eschew neuroimaging in favour of behavioural markers which reliably distinguish conscious and unconscious conditions in healthy controls. In order to furnish accurate diagnostic criteria, a mechanistic explanation of how the brain gives rise to consciousness seems desirable. Mechanistic and theoretical approaches could also ultimately lead to a unification of passive and active paradigms in a coherent diagnostic approach. In this paper, we survey current passive and active paradigms available for diagnosis of residual consciousness in vegetative state and minimally conscious patients. We then review the current main theories of consciousness and see how they can apply in this context. Finally, we discuss some avenues for future research in this domai
Scenario of the organic food market in Europe
Scenario analysis is a qualitative tool for strategic policy analysis that enables researchers and policymakers
to support decision making, and a systemic analysis of the main determinants of a business or sector.
In this study, a scenario analysis is developed regarding the future development of the market of organic
food products in Europe. The scenario follows a participatory approach, exploiting potential interactions
among the relevant driving forces, as selected by experts. Network analysis is used to identify the roles of
driving forces in the different scenarios, and the results are discussed in comparison with the main findings
from existing scenarios on the future development of the organic sector
These confabulations are guaranteed to improve your marriage! Toward a teleological theory of confabulation
Confabulation is typically understood to be dysfunctional. But this understanding neglects the phenomenonâs potential benefits. In fact, we think that the benefits of non-clinical confabulation provide a better foundation for a general account of confabulation. In this paper, we start from these benefits to develop a social teleological account of confabulation. Central to our account is the idea that confabulation manifests a kind of willful ignorance. By understanding confabulation in this way, we can provide principled explanations for the difference between clinical and non-clinical cases of confabulation and the extent to which confabulation is rational
An embedded real-time co-processor for control applications
In this paper we present a high performance real-time microcontroller (uRT51) based on an 8051 core. The uRT51 is an 8-bits processor that includes a Real-Time co-processing unit. We have implemented the speed control of a DC motor to evaluate the uRT51 performance. The uRT51 shows a control performance suitable for low-cost, low-power, embedded real-time control applications in which real-time systems based on RTOS failVI Workshop de Procesamiento Distribuido y Paralelo (WPDP)Red de Universidades con Carreras en InformĂĄtica (RedUNCI
Geography of Scientific Knowledge: A Proximity Approach
The geography of scientific knowledge is defined as the replication process of locally produced knowledge claims. Proximity in social, cognitive, and physical dimensions promotes the sharing of tacit knowledge. Thus, given the complementarity between tacit and codified knowledge, proximity supports the replication of codified knowledge claims. Distinguishing between controversial and uncontroversial contexts, one can understand the sociology of science as explaining the behaviour of scientists from their proximity to other scientists, and the sociology of scientific knowledge as describing the processes that constitute the proximity between scientists.replication, knowledge claim, proximity, mobility, controversy, incentives, sociology of science, economics of science, geography of science, sociology of scientific knowledge
