PV systems in the vertical walls: A comparison of innovative structures
2016
This paper presents the performance comparison of PV windows with the purpose of tracing the behavior of next-generation systems, which could favor architectonical integration. More in detail, a dye sensitized solar cell (DSSC) and blue and grey thin film silicon panels have been analyzed. The systems can be placed behind a window or behind a wall of glass blocks. The three generation systems are then compared in terms of both efficiency and Fill Factor.
Future house automation
2015
In this paper, we propose the future house automation, a PLC-based embedded system that aims reducing the house energy consumption by optimizing the entire hardware assembly and software algorithms. The project started from the idea of designing a self-controlled house, to increase user's comfort in his daily environment, reducing the cost and optimizing the energy consumption. Our embedded application represents a green solution into a growing number of environmentally aware consumers, very suitable for the market of energy-efficient control systems. We provide a cheap solution for developing by everyone its own automation system control house. Therefore, our project contributes for helpin…
Peripheral Centralities: An Integrated Approach
2017
Un profondo cambiamento caratterizza a livello globale gli insediamenti urbani: ciò può essere osservato attraverso le relazioni tra centro e periferie. Le aree periferiche sono il banco dove il futuro delle città può essere opportunamente messo alla prova, in cui è possibile prefigurare la futura qualità della vita di individui e comunità. Sicurezza, sostenibilità, benessere che potranno essere raggiunti nelle aree periferiche saranno più rilevanti in termini quantitativi; invece il senso di identificazione e appartenenza, più forte nelle aree centrali, è debole o assente nelle periferie. Occorre puntare quindi a una sorta di centralità diffusa, applicando un approccio integrato, che si ad…
Analytical compact modeling of GMR based current sensors: Application to power measurement at the IC level
2010
An analytical compact model for giant magnetoresistance (GMR) based current sensors has been developed. Different spin-valve based full Wheatstone bridge sensors, with the current straps integrated in the chip, have been considered. These devices have been experimentally characterized in order to extract the model parameters. In this respect, we have focused on the sensors linear operation regime. The model, which allows the individual description of the magnetoresistive elements, has been implemented in a circuit simulator by means of a behavioral description language: Verilog-A. We also propose the use of the devices in a direct power measurement application at the integrated circuit (IC)…
Route Generating Algorithm Based on OpenSource Data to Predict the Energy Consumption of Different Vehicles
2015
This work presents an algorithm that can be used to generate a route, based on OpenSoure Data. The generated route considers different route conditions like speed limits, traffic information, traffic lights, wind, and topography. Based on a generated inner city and highway cycle it is shown why those conditions are important for the calculation of energy consumption, drive time and stop time.
New statistical post processing approach for precise fault and defect localization in TRI database acquired on complex VLSI
2013
International audience; Timing issue, missing or extra state transitions or unusual consumption can be detected and localized by Time Resolved Imaging (TRI) database analysis. Although, long test pattern can challenge this process. The number of photons to process rapidly increases and the acquisition time to have a good signal over noise ratio (SNR) can be prohibitive. As a result, the tracking of the defect emission signature inside a huge database can be quite complicated. In this paper, a method based on data mining techniques is suggested to help the TRI end user to have a good idea about where to start a deeper analysis of the integrated circuit, even with such complex databases.
Frequency mapping in dynamic light emission with wavelet transform
2013
International audience; Dynamic photon emission microscopy is an e cient tool to analyse today's integrated circuit. Nevertheless, the reduction of transistor's dimensions leads to more complex acquisitions where many spots can be seen. A frequency characterization of the whole acquired area can help to have a better understanding of it. With that purpose in mind, a new methodology to draw frequency mapping of dynamic light emission acquisition is reported. It is fully automated and based on wavelet transform and autocorrelation function. Regarding the possible use in an industrial context, the suggested method can help to localize abnormal emission activity and it gives some perspectives o…
Sub-mA current measurement by means of GMR sensors and state of the art lock-in amplifiers
2015
Electric current measurement at the range of μA in integrated circuit has been traditionally carried out by micro-electronically engineered systems, such as current mirrors or charging capacitors. However, off-line, i.e., non-intrusive methods provide advantages related to size and power consumption. In this sense, giant magnetoresistance (GMR) magnetic sensors are optimal due to their sensitivity and CMOS compatibility. In this work, we make use of specifically designed CMOS GMR-based current sensors in combination with a custom electronic interface based on a low-voltage low-power lock-in amplifier, demonstrating the capability of this combination for current measurement in the range of μ…
Noise and gain performance of PSA transistor series for personal communication systems vs. emitter number and operating conditions
1995
The booming market of communication system applications in the low microwave range put greater demands on the component performance at lower supply voltages and limited current consumption, as well as on production cost and integration level. In this work, we present the results of an extensive characterization activity carried out on several advanced polysilicon bipolar transistors as requested by the manufacturer. The devices were grouped according to their emitter finger number and were characterized over the 2-6 GHz frequency range in terms of noise, gain and scatterino parameters at different bias conditions. A comparative analysis has been performed to explore how the transistor perfo…
Development of 3D Anti-Swing Control for Hydraulic Knuckle Boom Crane
2021
In this paper, 3D anti-swing control for a hydraulic loader crane is presented. The difference between hydraulic and electric cranes are discussed to show the challenges associated with hydraulic actuation. The hanging load dynamics and relevant kinematics of the crane are derived to model the system and create the 3D anti-swing controller. The anti-swing controller generates a set of tool point velocities which are added to the electro-hydraulic motion controller via feedforward. A dynamic simulation model of the crane is made, and the control system is evaluated in simulations with a path controller in actuator space. Simulation results show significant reduction in the load swing angles …
