Description and objectives:

This project aims to design a system for detecting cracks in railway rails. In terms of the basic principle of detection, it is proposed here that this should be carried out by means of a radar technique using radiofrequency technologies with the capacity to illuminate the rail in movement. The reflections received must be processed to determine the presence of cracks smaller than those specified in the regulations before grinding the rail. The aim of this project is to make progress in specifying the basic principle of detection, and to investigate the needs for mounting on a moving element.

Description and objectives:

This project proposes the acquisition and implementation of novel platforms for the transformation of motion, radio frequency, sound or wind into energy usable by autonomous IoT systems. There are currently more integrated and more efficient platforms that promise to provide power to electronic data collection and remote connectivity systems, and it is important to understand the real scope of their capabilities. This refers to testing and merging the possibilities of harnessing unusual physical elements/events for these applications to replace the usual solar panels.

Description and objectives:

The Internet of Things (IoT) is driving research into increasing the connectivity of tagged items that are read wirelessly. However, the price of tagging millions of objects often makes the final application unaffordable. One possible strategy is to remove the chip from the tags and study their reflected signal in radar mode (chipless tags). Chip-free tags would exhibit a competitive advantage over their chip-based counterparts by an ostensible price decrease. In addition, environmental constraints, such as high temperatures, cause electronics to fail in certain aggressive scenarios and, therefore, eliminating it by an alternative route in these cases would be a gain. In this context, the identification and reading of chipless wireless sensors based on radar technology (backscattered signals) will be studied by applying sensor design, antennas, signal processing, RF electronics and Machine Learning.

The directionality of a traditional microphone is achieved by its mechanical-acoustic design. There is also the possibility of forming such a microphone by using several "normal" microphones and by means of signal processing techniques (beamforming) to obtain a joint directional characteristic. The project consists of documenting the state of the art and the current market for beamforming directional microphones, searching for suitable amplifiers and ADCs for further processing in a DSP, choosing an option and assembling it. For students of Industrial Electronics Engineering: no knowledge of signal processing is required.

The aim of this project is to achieve a device that intelligently measures the most representative gases of environmental pollution using the electronic nose concept, i.e. using signals from a sensor matrix and applying artificial intelligence methods, the system will be able to discern between different types of gases and their concentrations. Electronic noses are a tool of great interest in various fields: measuring food quality (oil, wine) or detecting diseases through breath. The project will provide students with training in the field of sensors and signal processing. Programming skills will be an asset.

  • Title:
    Study of the use of the TDR technique in solder analysis of BGA encapsulates

  • Description and Objectives:

  • The Time Domain Reflectrometry (TDR) technique is used to study the characteristics of a transmission medium (lines and/or waveguides) based on the analysis of the reflected waves produced in it. The idea of the project is to use Agilent's ADS tool intensively to delimit the main conditions that the medium, the generator and the TDR analyser must fulfil, in the case of the analysis of soldering of BGA encapsulates, by means of this technique.

  • Title:
    Diver voice correction.

  • Academic Supervisor:

  • Recommended profile:
    Degree in Communications Electronics Engineering
    Degree in Telecommunication Systems Engineering

  • Description and Objectives:
    Divers working at great depths breathe a mixture of helium and oxygen (heliox), because at high pressures nitrogen is harmful. However, this mixture causes a change in the voice, which takes on a Donald Duck-like characteristic and becomes practically unintelligible. One of the solutions to this problem is to construct a map in which the spectra of different sounds produced in heliox and in air by the same person are related. The voice produced in heliox is corrected by changing the spectrum of each sound by its corresponding spectrum of normal voice. The aim of this project is to investigate a number of changes and possible improvements in the quality of the corrected speech for an existing Matlab design of such a system.

    Internal communication system for large MPVs

  • Recommended profile:

  • Description and Objectives:
    In large MPVs it is quite difficult to maintain a conversation between passengers in different rows due to a higher noise level than in conventional passenger cars. The aim of this project is to review the ideas for solving this problem proposed so far, to design a multi-channel internal communication system with echo cancellation, to simulate it in Matlab and to realise a prototype based on a C6713DSK DSP board equipped with a multi-channel audio interface and to test it in a car.

Electronic systems

Description and objectives:

In today's industrial processes it is increasingly necessary to monitor the manufacturing process and the quality of the components resulting from the process. There are a variety of methods that allow such monitoring in real time, that do not require parts to be separated from each other for analysis and that do not damage the parts in the process. The most commonly used inspection techniques are those using electromagnetic fields, ultrasonic signals and machine vision. This project deals with ultrasonic techniques. Ceit has its own ultrasonic signal test bench that allows ultrasonic signals to be generated and captured easily from a PC. The aim of the project is to make a proposal for the design of a miniaturised test bench (e.g. the size of a Raspberry). By comparison, the current design is the size of a desktop computer. It would involve making a block diagram of the system, making a selection of components including the processing platform to be used and the power supply components. Finally, it will be necessary to estimate the consumption and cost of the final equipment.

Description and objectives:

CEIT's additive manufacturing and laser group has a modern and precise laser system that generates 100-femtosecond pulses to engrave surface textures on different types of materials. The aim of this project is to evaluate the maximum definition of the equipment to define lines on thin gold films for application in the high-end consumer products industry. The achievable definition is expected to be less than one micrometre. The student will learn to use the laser tool for materials processing, acquire and use advanced optical concepts, and use nanometre resolution metrology systems (afm, profilometry, microscopy) to characterise the equipment.

Positioning and communications

 

Description and objectives:

This project aims to propose novel techniques to achieve indoor and outdoor positioning by means of signals of opportunity, in combination with GNSS satellite signals (GPS, Galileo, etc.). The current trend is to fuse the GNSS signal with inertial sensors and vision and radar based sensors for precise guidance. However, there are less expensive techniques using signals already present in the spectrum and in the application environment that can be useful. Wifi and Bluetooth beacons can be used as anchors and fingerprinting techniques based on received power can achieve accuracies in the order of a few metres. However, the new 5G, with higher frequency spectra and smaller cells, can be useful for positioning by signal arrival time. There are also constellations of commercial satellites in low orbits that emit signals that can also be used for this purpose.

The aim is to establish the techniques used in each case and to arrive at an estimate of the achievable accuracies.

Description and objectives:

In this GFP, the programme Lumerical, which is an FDTD optical simulator, will be used to simulate different optical elements. Optical elements have dimensions typically between 0.1 and 10um, they can be used as diffraction gratings, optical filters, mirrors or anti-reflection layers. Therefore their optical properties must be estimated as accurately as possible. With the help of CEIT's technical staff, it will be possible to fabricate these devices and evaluate the accuracy of the simulations performed.
