Correct nuclide identification is critical for first responders. It is the final result of the complex chain occurring in a detector: a spectrum with poor statistics in a variable environment is recorded then analyzed. Industries are facing a complex challenge, as they have to design instruments that can identify materials that for the most part are difficult to obtain. Modelling a source is a viable...
The study is a metonym for designing a Fuzzy Logic Controller (FLC) using various types of membership functions (MFs) and variable rule-base (RB) for a DC servo speed control application. FLCs are more useful in comparison to their crisp counterparts for attaining a desired speed in a closed loop process. Based on prior experience, the control methodology i.e. RB of a FLC is designed which comprises...
The intent of our study, conducted on a sample of 98 psychiatric outpatients, was to explore the correlations between executive functions and traits of temperament and character. Executive functions were assessed through Frontal Assessment Battery and the traits of temperament and character using the Temperament and Character Inventory. From our sample, a significant link between certain traits of...
Memory access tracing is aprogram analysis technique with many different applications, ranging from architectural simulation to (on-line) data placement optimization and security enforcement. In this article we propose a memory access tracing approach based on static x86 binary instrumentation. Unlike non-selective schemes, whichinstrument all the memory access instructions, our proposal selectively...
Many theoretical and empirical studies that analyze the factors associated to academic achievement identify gender as a highly significant element. Within the assessment of information literacy skills, the effect of gender seems apparent. However, the contextual nature of gender makes it difficult for the results of the studies to result in specific improvements and innovations in the schools. The...
As high performance computing (HPC) systems reach exascale proportions, the cost of simulation in time and resources increases. Tools for selecting representative parts of parallel applications to reduce simulation cost are widespread, e.g., BarrierPoint achieves this by analysing abstract characteristics such as basic blocks and reuse distances. However, architectures new to HPC will have a limited...
En este trabajo se presentan los resultados de una evaluación aplicada a un conjunto de elementos notacionales en sistemas interactivos. La evaluación se realizó con el fin de: 1. Validar las categorías de una Taxonomía de la Actividad para Sistemas Interactivos y 2. Analizar el nivel de comprensión que tienen los ingenieros y estudiantes, que practican el Desarrollo de Sistemas Interactivos, acerca...
In this paper, we present the idea that game design, player modeling, and procedural content generation may offer new methods for modern psychological assessment, allowing for daily cognitive assessment in ways previously unseen. We suggest that games often share properties with psychological tests and that the overlap between the two domains might allow for creating games that contain assessment...
Hand-held robotic instruments are developed to compensate physiological tremor in real-time while augmenting the required precision and dexterity into normal microsurgical work-flow. The hardware (sensors and actuators) and software (causal linear filters) employed for tremor identification and filtering introduces time-varying unknown phase-delay that adversely affects the device performance. The...
PISim is a new piece of software that is being developed to support teaching and learning in process control. The ideas behind PISim are discussed and the results of two tests of the alpha build (with industrial participants and as part of a scheduled class) are presented. The effect of the test results on the direction of future development is also considered.
The demand for near real-time analysis of streaming data is increasing rapidly in scientific projects. This trend is driven by the fact that it is expensive and time consuming to design and execute complex experiments and simulations. During an experiment, the research team and the team at the experiment facility will want to analyze data as it is generated, interpret it, and collaboratively make...
This paper describes a linear programming (LP) approach for solving the network utility maximization problem. The developed approach is inspired by a convex relaxation technique from non-convex polynomial optimization methods. In contrast to most of the existing results where concavity of the network's utility function is often assumed, the proposed LP approach may still be used to solve the NUM problem...
PNNL's Center for Advanced Technology Evaluation (CENATE) is a new U.S. Department of Energy center whose mission is to assess and facilitate access to emerging computing technology. CENATE is assessing a range of advanced technologies, from evolutionary to disruptive. Technologies of interest include the processor socket (homogeneous and accelerated systems), memories (dynamic, static, memory cubes),...
The purpose of this study was to examine the effects of student interaction with science role models on elementary school students' desire to participate in science. The main question asked was: How will desire to participate in science differ after adolescents are given an opportunity to interact with engineers employed in high-tech areas from a state-of-art research and education center? Results...
Nowadays designing a SAR Instruments is getting more and more complex. On one hand the requirements on resolution are always shrinking, leading to an increase of complexity in all the system, on the other the introduction of digital SW-reconfigurable architectures increased the number of functions and modes allocated to the same HW (mixed SAR modes, GMTI, etc.). Another important requirement that...
This study focuses on physical modelling of turbulent vertical buoyant jets, discharged into a transversal current and interacting with localized background turbulence. The physical model was developed in the Coastal Engineering Laboratory of the Technical University of Bari. The physical model consists of a sophisticated system that allows to monitor and adjust all the characteristic parameters of...
The practice and the hands-on are essential for technical and professionals skills, even in controlled situations. Due to that, the use of laboratories during the learning process is fundamental, although it has been more difficult to support such kind of infrastructure locally, which brings the challenge to find alternatives. On the other hand, the Brazilian law establishes that higher education...
The analytical expressions for trapezoidal and triangular signals arbitrary order q integral factors of harmonics are obtained by using the infinite series harmonic synthesis formulae. Since the only first order coefficient of the differential factors of harmonics can be calculated this way for these signals, the before offered LabVIEW virtual instrument is modified for the up to third order integral...
Assessments constitute a crucial part of an academic learning process due to its importance in evaluating students' knowledge and forming a basis for their grade. The rapid evolution of technology has influenced the way assessments are now being conducted in academic institutions. Tertiary institutions are adopting Computer-Based Assessments (CBAs), in tandem with traditional Paper-Based Assessments...
Occupant behavior determines a large share of the energy consumption of buildings. Software applications driven by information about occupant behavior provide a mean to optimize this share. However, existing systems for sensing occupancy behavior provide technology-specific APIs statically coupled to the type of computed occupancy information. Software platforms for developing applications for buildings...
