1. Comparison of Relative Loudness Judgment in Children using Listening Devices with Typically Developing Children
Abstract Introduction Loudness perception is considered important for the perception of emotions, relative distance and stress patterns. However, certain digital hearing devices worn by those with hearing impairment may affect their loudness perception. This could happen in devices that have compression circuits to make loud sounds soft and soft sounds loud

2. ELECTRICAL NOISES REDUCTION IN NANOPORES EXPERIMENTS BASED ON CONSENSUS FILTER
Nanopore has developed into an indispensable tool for single molecules experiments, where useful information about the characteristics of DNA/RNA can be obtained from the flowing of ionic current elicited by individual molecules as they traverse a single nanometer-scale aperture. However, due to the relatively high background current noise and low measuremen

3. Design of a Microstrip Diplexer and Triplexer Using Open Loop Resonators
Abstract In this paper a novel design of microstrip diplexer and triplexer using open loop resonators is presented. The proposed diplexer if formed by two band-pass filters for the Industrial Scientific Medical (ISM) applications at 5.8 GHz and the WIMAX applications (IEEE 802.16 WiMAX at 3.17 GHz to 4.2 GHz bands). The microstrip triplexer is designed for t

4. Electromechanical Impedance - Based Structural Health Monitoring Instrumentation System Applied to Aircraft Structures and Employing a Multiplexed Sensor Array
ABSTRACT: The electromechanical impedance method has been seen as a promising tool for structural health monitoring regarding different types of structures and purposes. Most importantly, this method can be used in real-time applications. Frequently, massive, high-cost, single-channel impedance analyzers are used to process the time domain data, aiming at ob

5. Galvanic vestibular stimulator for fMRI studies
INTRODUCTION: Areas of the brain that are associated with the vestibular system can be activated using galvanic vestibular stimulation. These areas can be studied through a combination of galvanic vestibular stimulation with functional magnetic resonance imaging (fMRI). In order to provide an appropriate sequence of galvanic stimulation synchronous with the

6. Lasic process: um framework conceitual para integração de padrões de gestão ao desenvolvimento de projetos de propriedade intelectual de sistemas eletrônicos integrados em chips (IP-SOCS)
This work is presented as a contribution to the field of design of digital systems integrated on chips (SoCs). Its main focus is to develop and deploy a (new) conceptual framework for the implementation of digital integrated circuits, with a strong emphasis on project management, called LASICProcess. As a natural consequence of the work and serving as a proo

8. Detecção de defeitos do tipo Resistive-Open em SRAM com o uso de lógica comparadora de vizinhança
The world we live today is very dependent of the technology advance and the Systemson- Chip (SoC) are one of the most important actors of this advance. As a consequence, the Moore s law has been outperformed due to this strong demand on the SoCs for growth, so that new silicon technologies has emerged along with new fault models that decreased the reliabilit

9. Relationships between dendritic morphology, spatial distribution and firing patterns in rat layer 1 neurons
The cortical layer 1 contains mainly small interneurons, which have traditionally been classified according to their axonal morphology. The dendritic morphology of these cells, however, has received little attention and remains ill defined. Very little is known about how the dendritic morphology and spatial distribution of these cells may relate to functiona

10. Modeling and simulation of device variability and reliability at the electrical level
In nanometer scale complementary metal-oxide-semiconductor (CMOS) parameter variations pose a challenge for the design of high yield integrated circuits. This work presents models that were developed to represent physical variations affecting Deep- Submicron (DSM) transistors and computationally efficient methodologies for simulating these devices using Elec

11. Design of self-checking fully differential circuits and boards
A design methodology for on-line testing analog linear fully differential (FD) circuits is presented in this work. The test strategy is based on concurrently monitoring via an analog checker the common mode (CM) at the inputs of all amplifiers. The totally self-checking (TSC) goal is achieved for linear FD implementations provided that the checker CM thresho

12. [email protected] um rolê pelas ruas da cultura digital
Rolê, in urban slang means to walk around, to go for a walk. Following this definition, this research walks through files posted by urban writers, in the great computer‟s world wide net. The technological advance allowed great changes in the way we communicate to each other. The spaces for human relationship have spread, and are also cyberspace and th
