The physical rehabilitation games characterized by natural user interfaces expressed by 3D motion capture sensors are in continuous development. Using these exergames the physician can access useful information about the patient rehabilitation process through the metrics such as angle of inclination of the neck, arm, forearm, trunk, posture, pushing force at the foot, etc. A physical rehabilitation system based on a computer game that uses the Kinect platform is presented in this paper. The system was developed by a research team from University of Suceava, Romania in collaboration with a research team from ISCTE Lisbon, Portugal. The exergame is designed and implemented for upper limb rehabilitation. The user's avatar passes through an orchard with apples and has to picks up the red or green apples according to their level. Our study presents that the exergames are a novel and useful tools in physical rehabilitation because people with motor impairments, may accept the training based on serious games with less reluctance considering the advantage of training in their homes.

Lately, pulse rate variability (PRV) analysis has been intensely studied, being used as an alternative to heart rate variability (HRV) for portable systems available on the market. Due to the simplicity of the waveform in comparison to that of the electrocardiographic signal (ECG), the photoplethysmographic (PPG) analysis is considered an interesting method for determining HRV parameters. In this paper, we have analyzed the HRV and PRV in time domain and frequency domain. In doing so in this study we have used 17 simultaneous records of both ECG and PPG signals have been used. We have compared the results and determined where the biggest differences occurred, some being noticeable in time domain parameters and others in frequency range parameters as well. Most correlations between HRV and PRV parameters, both in time domain and in frequency domain, are over 0.96. This enable us to establish the fact that there is a link between HRV and PRV parameters. We have analyzed attentively a particular case in which we obtained the lowest HRV and PRV correlation value in the frequency domain. The result was improved after we used a time series correction. It was therefore concluded that we can determine the HRV parameters based on the PPG signal in resting situations.

Current trends in the automotive industry are geared towards the development of partially or completely autonomous drive systems. The new regulations imply increasing the security level in operation and meeting minimum requirements for fault mode assistance. In this context, the provision of redundant solutions becomes imperative. Another critical requirement is to achieve a high degree of efficiency (minimum energy consumption). This involves the development of actuation systems and specific control algorithms that increase safety, efficiency and fault tolerance behavior. Based on the abovementioned aspects, this paper proposes a study on a redundant drive concept that can be successfully integrated into the steering or brake systems of current vehicles and also fulfils the basic requirements for autonomous driving. In order to validate the theoretical aspects contained in this study, two distinct ways of modelling and simulation were used: FEM (Finite Element Method) analysis and equivalent mathematical equations implemented in MATLAB / Simulink software environment.
目前汽车行业的发展趋势是部分或完全自动驾驶系统的发展。新规定意味着提高运行中的安全级别，并满足故障模式辅助的最低要求。在这种情况下，提供冗余解决方案变得势在必行。另一个关键要求是实现高度的效率(最小的能耗)。这涉及到驱动系统和特定控制算法的发展，以提高安全性，效率和容错行为。基于以上几个方面，本文提出了一种冗余驱动概念的研究，这种冗余驱动概念可以成功地集成到现有车辆的转向或制动系统中，同时满足自动驾驶的基本要求。为了验证本研究所包含的理论方面，采用了两种不同的建模和仿真方法:FEM (Finite Element Method)分析和在MATLAB / Simulink软件环境下实现的等效数学方程。

Power transformers are vital components of the power system. These electrical devices can experience multiple types of faults within them. Mechanical defects are relatively difficult to detect since they occur inside the structure of the power transformer. Magnetostriction can create this type of faults in magnetic core and electrodynamic forces can cause them in windings. Diagnostic methods mainly use vibration information from the surface of transformer. This is an indirect approach and causes additional errors since vibrations need to propagate transformer structure before sensors receive them. However, it is possible to calculate the mechanical situation in windings by modelling this part of the transformer as a mass and spring system with forces acting upon it and applying dynamic genetic algorithm. This paper describes a model created in COMSOL and Matlab software and a case study for a segment of windings displays the acquired results.

Nowadays, electricity demand significantly increases along with reduction of negative impacts to environment leads to a strong development of renewable energy which includes solar energy. In order to be able to provide power for the load, photovoltaic (PV) has to receive solar radiation to convert into electricity, through the converters to obtain such responses as voltage, frequency, etc. suitable for the load. However, this conversion creates the harmonics, one of the factors that reduce power quality and damages the devices. This paper studies two passive single-tuned and double-tuned passive filters coupled with converters for off-grid solar system. By means of simulation from Matlab/Simulink software, a solar conversion system and filters are built to meet the load requirements of 1kW and rated voltage of 220V. The results show that the double-tuned filter offers better harmonics filtering than the single-tuned filter, very low output voltage distortion for stable loads.

This work presents an architecture as an important contribution regarding to emotional events along tasks based on flight simulations. This architecture considered eight beginner users of flight simulator (n = 8) while they execute a simulated flight according with the basic concepts of visual flight rules (VFR). The acquired physiological sensing were: heart rate (HR), electroencephalography (EEG) and galvanic skin response (GSR). One small camera was also used to record the users’ face in order to extract, after the post-processing, the emotions of the user during the flight. The considered emotions were: happy, sad, angry, surprised, scared and disgust. Initial analysis of the GSR signals shown that the takeoff task presented 13% more variability (or emotional events) between the climb and approach tasks together; and in the same way, the landing task presented 16% more variability between the climb and approach tasks together, what shows the importance of these researches in flight safety context, mainly in these critical phases.

The Internet of Things (IoT) is an ecosystem of computer devices, people or animals which hold unique identifiers and have the ability to transfer data over the network without involving human-to-human or human-to-computer interaction. Over the years, there have been a number of challenges in building a scalable IoT system. These challenges include asynchronous communication, for which we propose a solution developed within the PrivateSky project [1], based on the representation of the asynchronous code as a set of phases in a workflow, which we will present in Section 4.

The IoT concept plays an important role in healthcare systems. This paper presents a sensors network based on interdigital capacitive sensor that is incorporated in clothes in order to build a device for screening and management of patients with Diabetic Neuropathy. The use of interdigital capacitive sensors embedded in clothes is a viable manner for monitoring the tremor of various parts of the body, including legs, neck and head. This method of monitoring, using capacitive sensors inserted in clothes is proper for the analysis of the subject's daily activity and in order to determine the patient's evolution and early detection of the modifications produced by Diabetic Neuropathy. Future work would supplement the system with wearable photovoltaic modules, or other solutions to guarantee energetic independence of the system.
