Design of a Multimodal Interface based on Psychophysiological Sensing to Identify Emotion

This work proposes a design of a multimodal interface to classify or estimate emotion states. Thus, 7emotions are considered such as:anger, boredom, disgust, anxiety/fear, happiness, sadness and normal.A couple of sensing technologies such as: galvanic skin response (GSR), heart rate (HR), electrocardiography (ECG), oxygen saturation (SpO2) and electroencephalography (EEG)are used to collect psychophysiological signals in relation with emotion state estimation. The International Affective Picture System (IAPS) dataset is used to design the classifier system. Regarding the classification task, a comparison between artificial neural networks (ANN-MLP) and support vector machine (SVM) is presented. The tests were carried out for 20 healthy volunteers ( ) of both genders with age from 23-50 years old. The proposed classifier presents accuracies of 85.71% when using ANN-MLP and 77.14% when using SVM.

A MATLAB Graphical Interface to evaluate the CC2650 Sensor Tag

This paper presents a MATLAB based graphical interface to evaluate the Bluetooth Low Energy (BLE) CC2650 Sensor Tag. Although this module contains more sensors, this paper considers the movement sensor which is composed of a gyroscope and an accelerometer. This sensor communicates by BLE with a PC that contains a USB BLE Dongle. Our contribution is to implement the application that allows using several scenario tests to evaluate this movement sensor. Thus, the accelerometer can be used to measure the pitch and role angles when the sensor is not moving linearly. The gyroscope is used to measure these angles as well as the yaw angle when the sensor is performing a linear movement. The graphical interface allows scanning of the BLE devices, establishing the link with one device, configuring the parameters of the device and displaying the time variation of angular rate, angular position and accelerations among others. There is the possibility of these measurements to be displayed in real time or off line, when all the data were acquired and processed. In this way the sensor can also be used to determine the trajectory of a person in an indoor environment.

Coplanar Capacitive Matrix Structures Used for Monitoring the Recovery of Burn Injuries

This paper presents a study regarding a coplanar capacitive matrix structure used for monitoring the burn injuries recovery process. The monitoring method presented can be applied for superficial burns (first degree) and partial thickness burns (second degree). The aim of this paper is to confirm the simulation results through a practical experiment. Constructive aspects regarding the coplanar capacitive structure are also presented. In order to predict the behavior of the implemented structure in the vicinity of a burn injury, several functional simulations were made. In this case, the electrical relative permittivity of the environment was changed according to different imposed conditions. Laboratory measurements were performed in order to reproduce as close as possible the real situations. The experimental results show that the presented method can be a viable alternative to actual methods used for monitoring the burn injuries, not necessarily by replacing them, but mostly to provide additional information to the medical staff.

A Case Study In Water And Wastewater Systems’ Energy Efficiency

World economy is closely related to energy and to how it contributes to the modernization of the society, by raising the standard of living and the degree of civilization of the population. In this context, water supply systems are attractive for energy efficiency, occupying an important place in the hierarchy of energy consumers. The purpose of this paper is to present some important aspects of a case study that must be considered in order to respond to specific requirements of water supply systems and it also shows a few measures that can be implemented with or without investments in order to reduce costs and energy consumption.

Characterisation of transmission of digital signals trough stainless steel conductive thread embroidered in T-shirts

This paper studies the electrical properties of ultra-thin stainless steel conductive thread wires embroidered into cotton. This study investigates the possibility to use the wires as interconnects between electrical modules that are measuring the human body’s electrical signals. The focus is on using common and commercially available materials and parts in order to demonstrate the feasibility and easiness of supplying power and digital signals to devices integrated into common clothing, such as a cotton Tshirt. In order to get as close as possible to real world scenarios, ex. where an athlete can wear this T-shirt, several tests have been identified, like causing mechanical strain and shearing, using salt water to simulate heavy perspiration and putting in parallel uninsulated signal transmission lines to determine the data loss rate. The goal of the study is to prove that uninsulated conductive stainless steel embroidered wires are a solution to today’s needs for interconnecting devices in clothing and also to come forward with improvements that can be brought to future developers of such systems.

A Method to Reduce Influence of Gain Errors and Offsets of Internal Components on Performance of Adaptive Sub-ranging ADCs

The paper proposes a method of designing and calibrating of an adaptive sub-ranging ADC that is robust to both gain errors and offsets of the components of its analog part, which may simplify and reduce the costs of manufacturing of adaptive ADCs. For facilitation of postproduction calibration, we propose a method of measurement of the actual gain and offset of particular analog tracts used in subsequent stages of conversion, that utilizes the subADC already present in the analog part of the adaptive ADC. Efficiency of the proposed approach is discussed and evaluated on the basis of the results of simulation experiments.

Fiber Optic Pressure Sensor

The purpose of this paper is to analyze the inherent and induced effects of the perturbations that result in losses of the optical power on the fiber measuring element of pressure/force detectors. Inherent or induced perturbations result in losses of the polarization state and optical power on the fiber. The presence of outer mechanical stress (pressure or tensile force) on the fiber results in the microbending loss phenomenon embedded in the optical fiber. The paper deals with both modeling and simulating the sensor behavior and with measurements on a physical sensor.

FluoLab: A New Easy-to-use Graphical User Interface for the Multi-cell Functional Calcium Signals Analysis

The progress in fluorescence microscopy and information technologies have completely transformed the study on living cells improving the capability to quantify, investigate and analyze, in time and space, single phenomena occurring inside and outside cells. We developed an user-friendly Graphical User Interface (GUI) able to extract and analyze ion calcium (Ca2+) signals and to understand how they regulate cell behavior and metabolism. The software, named FluoLab (Fluorescence Laboratory), works on acquired confocal fluorescence microscopy images and allows to obtain signals of Mean Fluorescence Intensity (MFI). Afterwards, the fluorescence signals are automatically converted in ion calcium concentration values, [Ca2+], expressed in microMolarity (µM), by using the specific dissociation constant Kd for each kind of fluorescent probes chosen for the experiments. It is possible to analyze contemporaneously more than one object through the Region Of Interest (ROI) defined around them and to follow them in time. FluoLab can also show a normalization of the obtained data, compensating automatically the image background and generating a file that can be used for a fast data analysis.
