    In this paper a method combining different types of simulation is used to evaluate transient interferences over a digital communication system at its frequency band. The method combines different simulation stages; the first one is an electromagnetic simulation, with FDTD numerical method, which is carried out to establish the level of the interference coupled to the digital communication system; at the second stage, the simulation of the transmitted data at the communication system is performed introducing the EM interference calculated at the first stage. The result of this co-simulation will be a BER and other useful indicators to quantify the degradation produced by the transient interference. To show the effectiveness of the co-simulation method first of all the method is validated comparing the results with other evaluation techniques, measuring a real interference over an RFID system. The RFID system is according to the ISO 14443 type B standard, and the interference generated is a burst according to 61000-4-4. Once the co-simulation method is validated, the co-simulation system is used to quantify and decide if an EMC redesign technique of the previous scenario is efficient enough to avoid degradation at the RFID system produced by the burst transient interference.

    As a consequence of increasing life expectancy, the promotion of lifestyles that allow aging wellbeing guarantees has acquired great importance in the developed countries. However, the adherence to healthy behaviors in young and adult people remains as a big problem in the community health field. The development of markers of adherence to healthy lifestyles and the evaluation its effectiveness is a goal of many research groups. This paper presents a system for analyzing physiological, psychological and behavioural user’s habits using a smartphone and externals biodevices. We use an Android smartphone with an internal tri-axial accelerometer and GPS to monitor physical activity. The smartphone is connected via Bluetooth to a respiratory sensor for breath monitoring. In addition, Android application contains psychological questionnaires to analyze user’s mood state and at the same, social interaction is analyzed tracking phone usage and user’s social network. Finally, the collected information is sent to a remote server for a long-term processing.

    In this paper, the electromagnetic emission measurements of an hybrid bus are presented. The measurements were carried out in different modes, i.e.: pulling away, running and braking. With the tests performed we analyze vehicle radiated emissions, passengers' safety and radiated transient interferences. To characterize this singular vehicle insitu measurements were carried out where non-controlled interferences sources (TV, radio broadcasting, ...) have to be taken into account.

    In this paper a radiofrequency identification system according to standard ISO/IEC 14443 type-B is evaluated in presence of transient noise. This real time communication system working at 13.56 MHz is interfered in a controlled environment by different transient bursts varying their level, frequency and duration. The transient burst interference is applied in an AC main wire close to the system and the effect over the digital communication system is evaluated using two different methods. The first one is observing directly an RFID equipment in presence of transient signals, and the second one is capturing the interference in time domain an evaluating its effect by means of simulation. The RFID system is affected by these transient noises causing different types of errors. It is shown that it is essential to measure and evaluate in time domain the transient phenomena to ensure that the RFID system do not have susceptibility problems.

    The present article studies the influence of a car heatable windshield by means of an equivalent material that allows an appropriate meshing of the vehicle. This study has been performed analyzing the propagation of an electromagnetic radiated transient pulse generated by a wire inside a car with and without the windshield. The Finite Differences Time Domain (FDTD) is the method used to obtain the field coupled to antennas located inside and outside the car. We concluded that it is important to take into account the heatable windshield to make a suitable electromagnetic model of the vehicle.
