Di seguito l’elenco della prima call del 2017

1 – AQUA SMART. Digital sensor to measure the instantaneous flow of pressure networks

Project Manager: Prof. Fabrizio PIRRI

AquaSmart: the solution to water network losses

Water utilities are currently relying on obsolete, expensive, and labor-intensive analog methods to capture usage data in their networks. This lack of data coupled with the progressive deterioration of the network causes, on average in Europe, 30% of water losses (39% in Italy) . This problem generates additional costs for water utilities and, in the event of pipe breaks, the lack of potable water for end users.

How does it work?

A smart meter (patent pending), will replace current residential meters and will be able to measure water flow and pressure data in real time in an energy effienct way;

An innovative management software (based on “machine learning” and neural networks) that identifies the position of water leaks by interpreting the data collected by the new meters and, unlike other competing solutions, the need to realize long and expensive network models.

The objective of the Project is to develop a prototype of the complete solution composed by the sensor (1), an electronic control board to acquire the data from the sensor and send it (2) using long rage radio communications to the software (3) that will then store and analyze this data.

 

2- ARIA3. Module of ventilation and biological purification of internal and external air to an environment

Project Manager: Prof. Orio De Paoli

Aria3 is a ventilation system, composed of a device that uses the properties of the plants to purify the indoor and outdoor air and that contributes to the maintenance of the conditions of comfort inside, limiting the production of non-renewable energy. This device is the combination of nature and technology in a single element.

Aria3 is designed to be applied to the facade of buildings and it has a size suitable for every application.

The device is composed by:
– a metallic or wooden structure
– two windows
– heat exchanger
– the pot with the plants
– irrigation system (manual or automatic)
– lights
– display control

The polluted air (indoor and outdoor) enters in the system and the heat exchanger recovers the heat inside. The polluted air passes at first through the soil where it is absorbed and then through the leaves that capture the other pollutants. Finally the air enters indoor and it is purified, cleaned and it also has a good % of humidity.

Applications:
– Residential, commercial and industrial buildings, in skyscraper.
– The device can be used in new buildings or in buildings to be redeveloped.

Advantages:
– Necessary change of air inside, without introducing external pollutants.
– Improves the quality of the indoor air, with its recirculation’s system and indoor air purification’s system.
– Recovery of the heat from indoor space, so as to reduce the energy consumption for heating and cooling.
– The plants inside the device guarantees the optimum humidity in indoor spaces.

 

3- ATPC – Active Tire Pressure Control system

Project Manager: Prof. Stefano d’Ambrosio

The outputs of the calculations will be displayed on a user interface, to simulate how these data may be provided to the driver. In case the software-only solution is implemented on-board, the driver will still be in charge for manually adapting the tire pressure. Or, in case an automatic system is present on-board to manage autonomously tire inflation pressure, the calculated pressure can be provided as input to the actuators unit to inflate or deflate tires according to the need.

In this project, the software is running on a dedicated electronic hardware, which will be fed with data acquired from the vehicle electronic control unit through the diagnostic port (OBD), in addition to data acquired from the Tire Pressure Monitoring System, the GPS module and an inertial unit. These data will be provided to the experimental ECU through a vehicle simulator able to reproduce the CAN signals as originally acquired on-board. The software prototype will be coupled to the actuator unit of the ATPC – Active Tire Pressure Control system, developed and prototyped by the homonymous student team at Energy Department, Politecnico di Torino.

 

4 – COOLTIED. Cooling device for electric machines

Project Manager: Prof. Paolo Guglielmi

 

 

 

 

The present project aim to develop a specific cooling device for electric machines. The  development of such an element would allow for an easier integration of power electronic and electric machine, leading to a more compact and electromagnetic compatible solution. The speficic component will cool directly the copper inside the stator of the electric machine allowing also for the power electronic sustain and cooling.

These very nice features would be possible thanks to specific shapes in the electric machine and to the adopted materials actually available on the market.  The final result will be a real power electronic drive more than the sum of a power electronic box summed with an electric machine. The project starts with a real application based on previous project with a multiphase machine

 

5 – Condensatori per circuiti risonanti in applicazioni di potenza

Project Manager: Prof. Paolo Guglielmi

Il presente progetto è mirato allo sviluppo di condensatori realizzati tramite la tecnologia dei circuiti stampati multistrato per applicazioni ad alte tensioni, alte frequenze e alte correnti. Esempi classici di applicazione per i prototipi che si intendono realizzare sono tutti i sistemi legati al riscaldamento, alla saldatura, alla tempra e alla fusione tramite induzione elettromagnetica. In particolare, tale idea di tecnica realizzativa è nata per essere applicata alla realizzazione dei condensatori usati nei sistemi di ricarica wireless per veicoli elettrici sia a con veicolo fermo che in movimento. I condensatori realizzati possono superare i componenti attualmente disponibili sul mercato in termini di tensione tollerata, efficienza, dimensione e costo con precisioni di realizzazione estremamente elevate.

7 – Device and method for the detection of the motion of a passenger car and the estimation of its sideslip angle

Project Manager: Prof. Stefano Mauro

The technology has the aim of measuring the main typical quantities that describe the kinematic behaviour of  a vehicle by the sensors included in a common smartphone and without any connection to the CAN network. The measured data can be used to evaluate the driving style, and they can be applied in drivers’ training as well as in sporting environment to monitor and increase the performance.

The proposed system can carry out measures which now are performed by expensive sensor sets, that makes impossible for trainers and small racing teams to use these kind of data in their business. The final product will be an application for Android phones.

 

8 – VITAL-ECG.  Dispositivo indossabile per l’acquisizione di segnali elettrocardiografici (ECG)

Project Manager: Prof. Eros Pasero

VITAL-ECG è un dispositivo in grado di monitorare i parametri vitali più importanti richiesti per il monitoraggio della salute di un paziente. Un normale orologio da polso (del tipo smartwatch) permette con un semplice tocco di dito di rilevare l’Elettrocardiogramma, il battito cardiaco, il livello di saturazione dell’Ossigeno nel sangue, la temperatura, l’umidità superficiale e il movimento compiuto dal soggetto nelle ultime ore. Le informazioni sono visualizzate da uno smartphone, registrate e inviate a un centro di assistenza medica remoto. Una semplice analisi è anche in grado di segnalare eventuali possibili problematiche. L’aspetto più interessante del dispositivo è che non richiede alcuna tecnica particolare. È infatti sufficiente toccare l’orologio per avere in 10 secondi tutte le informazioni.

 

 

9 – Bromide enhanced ozonation of wastewater with high loads of ammonia nitrogen

Project Manager: Prof. Barbara RUFFINO

The patent is aimed at treating industrial wastewaters, containing high concentrations of ammonia, by using an ozonation process that avoids generation of nitrate.

The treatment is based on the optimization of an already-know process that uses the reaction between ozone and bromide to generate hypobromous acid (HOBr) and, through this, gaseous nitrogen.

With the PoC project we want to better understand the role of some boundary conditions on the success of the process and on the generation of unwanted byproducts (bromate, BrO3-).

BOUNDARY CONDITIONS:
– Ratio between O3 : NH4+ : Br
– pH and agents for its regulation (HCO3-, PO4=, citric acid or others)
– Presence of organic matter

Applications:
– Treatment of wastewaters originated from the adsorption of ammonia
– Purification of wastewater of municipal and industrial origin if natural bromide is present
– Purification and sanification of waters from aquaculture ponds in marine environments

Advantages:
– Rapid process for the ammonia removal
– No generation of sludge from precipitation processes
– No need of buffering species for wastewaters with high alkali content
– Control of the nitrate generation
– Low environmental impact

 

10 – Method for the controlled delivery of colloids in porous media

Project Manager: Dott. Tiziana Tosco

Over 1.2 million of contaminated sites across Europe. Only 60,000 already remediated. EPA estimated a cost of $250 billion to remediate 350,000 polluted sites in USA.
Nanoremediation is an innovative technology for the remediation of contaminated aquifers, which involves the subsurface injection of engineered nanoparticles (NPs) to create a reactive zone for in-situ treatment of pollutants.

PROS: It is a non-invasive and flexible approach, which can significantly reduce the time needed for the site restoration even in presence of strongly recalcitrant pollutants.

CONS: High cost of NPs and no control on NP distribution and long term fate.

The PROBLEM: In field applications, effective delivery and appropriate dosing of NPs is necessary for the correct emplacement of the in situ reactive zone and to minimize remediation costs. NPs need to be precisely delivered to the target zone and to be stable over time, to extend the remediation lifetime and to prevent their uncontrolled migration. NanoTune is an innovative method to precisely control the transport and distribution of NPs in porous media and optimize nanoremediation. The method involves the tuned injection of a stable NP suspension and of a retardant agent to induce the controlled and irreversible accumulation of nanoparticles within a target zone.

Tuned and Irreversible deposition of iron oxide NPs was achieved at the center of sand columns by applying the NanoTune approach in simple domains (laboratory scale). An integrated experimental – modelling approach was developed to design the case-specific injection protocol for NP immobilization in 1D geometry.

EXPECTED RESULTS:
– Technology tested and validated in extremely controlled conditions
– Model supported design for large scale applications
– Ready for testing in real field sites!
