We present some preliminary results of the numerical simulations of the hydrodynamic characteristics of an abdominal aorta aneurysm (AAA) patient specific test case. Images of the AAA lumen have been acquired in 10 discrete time-steps through a stabilized cardiac cycle by electrocardiogram-gated computer tomography angiography, and are used to approximate the in vivo, time dependent kinematic fields of the (internal) arterial wall. The flow field is simulated by a Smoothed Particle SPH numerical model, where the kinematics of the boundary of the computational domain (the internal aortic vessel) is the one computed by the above procedure. The outputs of the SPH model, i.e., pressure and flow field characteristics, are used to compute the stress strain tensor acting over the internal walls of the aorta. The two coupled approaches, i.e., 1) the procedure applied for the kinematics of the internal walls of the aorta and 2) the fluido-dynamic numerical model could constitute a new and fast tool to predict and prevent aneurysm rupture risk.

PEDOT:PSS is one of the most studied and used polymers. The current literature shows that this material is employed in solar cells, electrochemical cells, devices for energy storage and stretchable electronics. However films with thickness in the scale of hundreds of nanometres have the intrinsic limitation that must be deposited onto a solid and consistent substrate, thus leading to bulky devices. Moreover pristine PEDOT:PSS exhibits low conductivity and thus several treatments, such as drop casting or acid vapours exposure, are usually pursued to increase it. These methods however are not easily implementable in production lines. Here we show a freestanding conductive dark-PEDOT (d-PEDOT), obtained by a low cost and fast in-solution treatment by sulphuric acid. The proposed synthesis procedure is based on methods industrially implementable. The obtained paste is mouldable and allows for the fabrication of free-standing tens of μm thick foils, made as easily as scribing by an ink pen. Electrical characterization shows a conductivity of 500 Scm−1, which makes the new material a good alternative to standard and expensive metal contacts.

In this study, we deal with the inversion of frequency-domain electromagnetic data collected with devices with different configurations (varying inter-coil spacing, frequency, height from the ground). More specifically, we present the results of the application of a Gauss-Newton inversion algorithm based on a non-linear forward model onto several synthetic resistivity and magnetic permeability vertical profiles. In addition, we shortly discuss the inclusion into this inversion scheme of a quite novel stabilizing term, based on minimum (gradient) support, and promoting sparse reconstructions. We demonstrate the effectiveness of this sparse inversion algorithm on synthetic and real datasets.

In the paper the approximate model of power system elements adjusted for reactive power flow and voltage simulations is presented and the use of these models is demonstrated. The developed approximate models of power system elements are simple but when used in circuit simulations the fast and accurate reactive power flow solution is obtained. The performed reactive power flow calculations take into account corrections due to predetermined active power flow through circuit branches. The so derived values are accurate enough (error less than 1%) in cases where voltage angle across inductance model is less than 15 deg. The main advantage of the proposed approach is that the solution is directly calculated in one step, rather than using iterations. Due to this the proposed approach is handy and numerically efficient for use in power network modelling for hardware in the loop and real time applications, implemented on industrial grade programmable logic controllers (PLCs). Also the proposed approach can be efficiently used in projective model control applications. To demonstrate the versatility of the proposed modelling approach, these models are used to build up the circuit used for the simulation of voltage area controller operation. The voltage area control is modelled by two voltage control modes. The first one is keeping the area total exchange of reactive power close to zero until pilot node (PN) voltage is within the certain voltage band and the second one is imposing the predetermined the PN voltage reactive droop. Simulation results of area voltage control operating under different external and internal transient reactive sinks are presented and thoroughly explained.

River water samples were subjected to chemical and optical analysis. Pollution by city wastewaters was observed by increase of total nitrogen concentration (TN) and electric conductivity (EC) in water samples. In most cases pollution was followed by decrease of optical density at 254 nm $(text{D}_{254})$ (by 10-50%) due to high natural background values. Pollution changed fluorescence intensity (I) for protein-like fluorophores (increase by 10-120%) and humic-like fluorophores (±15%). Calculations showed that measurement of $text{D}_{254}$ with one detector was not informative for water quality monitoring because $text{D}_{254}$ for polluted waters were in the frames of seasonal variation for the unpolluted waters in suburban part of river. Increase of I was able to detect presence of 10-90% of wastewater with the background of unpolluted river water. The best parameter for this was I at excitation wavelength 230 nm and emission wavelength 350 nm. Relative parameter F showing ratio of protein-like I to humic-like I was not informative in pollution monitoring.

3D recording, digital surveying and mapping are efficient and manageable tools for reconnaissance, documentation and monitoring in underwater archaeology. Lab4Dive project, co-funded by the European Union's EMFF Programme, through the EASME and DG MARE call on “Blue Labs”, aims to design, develop and validate an innovative, marketable and competitive technology, which will assist underwater archaeologists in the field and will contribute significantly to the successful outcome of the survey process, documentation and preservation of submerged archaeological sites. In this article, the Lab4Dive system and its preliminary testing results, will be presented. The system is based on an underwater tablet coupled with an intelligent underwater case embedded with environmental sensors, a high-resolution camera and compatible with different commercial acoustic positioning systems, which will be integrated with a cloud data gathering system. During the dive, the tablet provides the diver with an augmented navigation interface, which guides him towards the selected targets. The cloud data gathering system allows the archaeologists to produce a 3D reconstruction of the site, which encompasses all the acquired information, enabling them to further study and analyze the data before the next mission.

The concept of load matching refers to the degree of agreement or disagreement of the on-site generation with the building load profiles: it can be increased and optimised with modifications on both the energy demand and generation. In this context, the paper presents the load match analysis of a case study: a modular housing construction (it has an area of 45 m2 and S/V ratio equal to 2.75 m−1) built in Messina (Italy). Moreover, in order to optimize the design of the next test module to be built, a parametric analysis was performed considering different scenarios on the generation side, to explore the effectiveness of the solutions sets used in current design and plan different solutions for the future ones. The results show that a 4 kWh energy storage system can increase the load cover factor by 94% (to 0.78) compared to the base case (0.41), while with only a 250 W fuel cell, the load cover factor can reach the value of 0.97.

In this paper, a classification method for the identification of the characteristic parameters of an unknown Longe Range (LoRa) signal is proposed. In order to reduce the effective sampling rate, the Compressive Sampling, a new acquisition paradigm that promises of exceeding the Nyquist-Shannon theorem, is used. In particular, values of sampling rate lower than 1Msamples/s have been experienced thanks to a proper random sampling strategy and the exploitation of discrete cosine transform (DCT) to achieve a sparse representation of a LoRa signal. Method performance are assessed by means of MATLAB simulations, using LoRa signals acquired with a proper experimental setup. Normal distributed noise vectors were added to each signal in MATLAB for a broad range of signal-to-noise ratio (SNR) values. As result, the obtained percentage of correct classification for each SNR value assures the reliability of the proposed approach in most operating conditions.
