In this extended abstract, we discuss recent research at Worcester into the inclusion of AI into ‘Serious Games’. Serious Games research intends to harness the power of computer game technology to produce educational and training materials. We prefer the name ‘Immersive Environments’ (IEs) since this emphasises the human psychological dimension. Creation of compelling and convincing learning software requires a rich engagement of the learner, and a convincing learning experience. We believe that various aspects of the AI tradition can inform the production of such learning.

Lo studio nasce dalla necessità di verificare l’applicazione di alcuni punti della ISO/TS 16949:2009 nel reparto di pressatura dell’azienda. Era importante valutare il livello di consapevolezza dei dipendenti relativamente al problema qualità in un’azienda automotive. Perciò, a partire dalla normativa, è stata fatta un’Indagine di Consapevolezza tra tutti i dipendenti il cui lavoro ha influenza sulla qualità del processo produttivo e del prodotto realizzato. Inoltre, serviva controllare se la logistica del reparto di pressatura fosse adeguata per permettere agli operatori di svolgere al meglio l’ autocontrollo, ossia un controllo in process delle quote geometriche e dimensionali durante la produzione di serie. È stata verificata l’adeguatezza delle unità di carico per la movimentazione dei prodotti, sia a livello logistico che di carico di lavoro per chi le deve movimentare. È risultato che le UdC attualmente in uso, ossia carrelli mossi manualmente, non possono essere sostituite, ma le si può rendere più maneggevoli cambiandone le ruote. Si è studiato il carico di lavoro del reparto di pressatura, per valutare se fosse possibile introdurre misure che diano la possibilità agli operatori di reparto di svolgere i controlli in process con più accuratezza, ipotizzando l’introduzione di una figura specifica, l’Operatore dell’Autocontrollo, che possa occuparsi solo di questo incarico, sollevando gli altri operatori da tale incombenza. Infine, ci si è posti il problema di ridurre l’utilizzo dei carrelli elevatori all’interno del reparto. È risultato necessario mantenerne l’uso per poter garantire la grande flessibilità nella produzione di quest’azienda, ma si è ipotizzato di separare il reparto in due diverse zone al momento del rinnovo del parco macchine, in modo da eliminarne l’utilizzo in una delle due zone e concentrarlo nell’altra, rendendoli indispensabili solo per un determinato tipo di produzione che si svolga in un settore ben definito del reparto.

The recent trend on embedded system development opens a new prospect for applications that in the past were not possible. The eye tracking for sleep and fatigue detection has become an important and useful application in industrial and automotive scenarios since fatigue is one of the most prevalent causes of earth-moving equipment accidents. Typical applications such as cameras, accelerometers and dermal analyzers are present on the market but have some inconvenient. This thesis project has used EEG signal, particularly, alpha waves, to overcome them by using an embedded software-hardware implementation to detect these signals in real time

Pavements tend to deteriorate with time under repeated traffic and/or environmental loading. By detecting pavement distresses and damage early enough, it is possible for transportation agencies to develop more effective pavement maintenance and rehabilitation programs and thereby achieve significant cost and time savings. The structural health monitoring (SHM) concept can be considered as a systematic method for assessing the structural state of pavement infrastructure systems and documenting their condition. Over the past several years, this process has traditionally been accomplished through the use of wired sensors embedded in bridge and highway pavement. However, the use of wired sensors has limitations for long-term SHM and presents other associated cost and safety concerns. Recently, micro-electromechanical sensors and systems (MEMS) and nano-electromechanical systems (NEMS) have emerged as advanced/smart-sensing technologies with potential for cost-effective and long-term SHM. This two-pronged study evaluated the performance of commercial off-the-shelf (COTS) MEMS sensors embedded in concrete pavement (Final Report Volume I) and developed a wireless MEMS multifunctional sensor system for health monitoring of concrete pavement (Final Report Volume II).

With the increasing significance of information technology, there is an urgent need for adequate measures of information security. Systematic information security management is one of most important initiatives for IT management. At least since reports about privacy and security breaches, fraudulent accounting practices, and attacks on IT systems appeared in public, organizations have recognized their responsibilities to safeguard physical and information assets. Security standards can be used as guideline or framework to develop and maintain an adequate information security management system (ISMS). The standards ISO/IEC 27000, 27001 and 27002 are international standards that are receiving growing recognition and adoption. They are referred to as “common language of organizations around the world” for information security. With ISO/IEC 27001 companies can have their ISMS certified by a third-party organization and thus show their customers evidence of their security measures.

This paper is a self-contained development of an invariant of graphs embedded in three-dimensional Euclidean space using the Jones polynomial and skein theory. Some examples of the invariant are computed. An unlinked embedded graph is one that contains only trivial knots or links. Examples show that the invariant is sufficiently powerful to distinguish some different unlinked embeddings of the same graph.

Current practices in agricultural management involve the application of rules and techniques to ensure high quality and environmentally friendly production. Based on their experience, agricultural technicians and farmers make critical decisions affecting crop growth while considering several interwoven agricultural, technological, environmental, legal and economic factors. In this context, decision support systems and the knowledge models that support them, enable the incorporation of valuable experience into software systems providing support to agricultural technicians to make rapid and effective decisions for efficient crop growth. Pest control is an important issue in agricultural management due to crop yield reductions caused by pests and it involves expert knowledge. This paper presents a formalisation of the pest control problem and the workflow followed by agricultural technicians and farmers in integrated pest management, the crop production strategy that combines different practices for growing healthy crops whilst minimising pesticide use. A generic decision schema for estimating infestation risk of a given pest on a given crop is defined and it acts as a metamodel for the maintenance and extension of the knowledge embedded in a pest management decision support system which is also presented. This software tool has been implemented by integrating a rule-based tool into web-based architecture. Evaluation from validity and usability perspectives concluded that both agricultural technicians and farmers considered it a useful tool in pest control, particularly for training new technicians and inexperienced farmers.

Uudet teknologiat mahdollistavat uusia kommunikaatiotapoja, mutta myös uusia tapoja sensuroida kommunikaatiota. Sananvapaus on perinteisesti levännyt vapaan journalismin ja sanomalehtien hartioilla, mutta internet-sivujen, blogikirjoitusten ja sosiaalisen median myötä ajatusten julkaiseminen globaalisti on entistä helpompaa. Ei kuitenkaan ole varmaa, että julkaistut ajatukset tavoittavat yleisönsä. Valtioiden lisääntyvästi harjoittama internet-sensuuri on siirtänyt sananvapauden haavoittuvimman kohdan painokoneista internet-yhteyksiin. Tämän tutkimuksen tarkoitus on tarkastella internet-sensuurin puolesta esitettyjen argumenttien eettisyyttä. Sensuurin puolesta esitetyt argumentit viittaavat yleensä tietyntyyppisen internet-sisällön, kuten pornografian, negatiivisiin vaikutuksiin, mistä syystä analyysissä käytetään Utilitaristista näkökulmaa. Iso Britanniassa käytetyn estolistan puolesta esitetyt argumentit otetaan tutkimuksen kohteeksi. Tämän tutkielman teoria pohjautuu Utilitarismin etiikkaan, sananvapauden filosofiaan ja internet-sensuurijärjestelmien tekniseen toimintaan. John Stuart Millin mukaan ihmisten sananvapautta ei tule rajoittaa, elleivät he estä muiden ihmisten mahdollisuuksia onneen. Tämän ajatuksen nojalla on tarpeellista tarkastella internet-sensuurijärjestelmien teknistä toteutusta, jotta niiden käytön todelliset seuraukset voidaan selvittää. Teknisistä järjestelmistä käytetään usein erilaisia metaforia, mutta metaforat voivat usein yliyksinkertaistaa teknisiä yksityiskohtia tai esittää niitä väärässä valossa, eivätkä tätä syystä riitä analyysin pohjaksi. Tutkielman löydökset näyttävät, että internet-sensuurin hyväksi esitetyt argumentit eivät ole päteviä Utilitaristisen analyysin pohjalta. Tutkitun internet-sensuurijärjestelmän utiliteetti on negatiivinen ja huonompi kuin filtteröimättömän internet-yhteyden utiliteetti. Aikuissisällön aiheuttamaa vaaraa lapsille on liioiteltu, ja lapsuuden suojelemiseksi rakennetuissa järjestelmissä on suuret mahdollisuudet väärinkäytölle ja tahattomille negatiivisille seurauksille. Sananvapaus on yhteiskuntamme perusta. Se on työkalu konfliktien luomiseksi ja selvittämiseksi rakentavalla tavalla yhteisten totuuksien löytämiseksi. Tutkitut argumentit eivät anna erioikeuksia sensuuriin.

Water scarcity is a global issue that has already affected every continent. Membrane technology is considered as one of the most promising candidates for resolving this worsening issue. Among all the membrane processes, the emerging forward osmosis (FO) membrane process is osmotically-driven and has unique advantages compared with other traditional pressure-driven membrane processes. One of the major challenges to advancing the FO membrane process is the lack of a suitable membrane. Polyelectrolyte thin film prepared via layer-by-layer (LbL) technique has demonstrated its excellent performance in many applications including electronics, optics, sensors, etc. Recent studies have revealed the potential of polyelectrolyte thin films in acting as the active separation layer of FO membranes, but significant efforts are still needed to improve the membrane performance and understand the transport mechanisms. This dissertation introduces a novel approach to prepare a zeolite-embedded polyelectrolyte composite membrane for enhanced FO performance. This membrane takes advantages of the versatile LbL process to unprecedentedly incorporate high loading of zeolite nanoparticles, which are anticipated to facilitate water transport due to the uniquely interconnected structure of zeolites. Major topics discussed in this dissertation include: (1) the synthesis and evaluation of the polyelectrolyte-zeolite composite FO membrane, (2) the examination of the fouling resistance to identify its technical limitations, (3) the demonstration of the membrane regenerability as an effective strategy for membrane fouling control, and (4) the investigation of crosslinking effects on the membrane performance to elucidate the transport mechanisms involved in the zeolite-embedded polyelectrolyte membranes. Comparative studies have been made between polyelectrolyte membranes with and without zeolite incorporation. The findings suggest that the zeolite-embedded membrane, although slightly more susceptible to silica scaling, has demonstrated enhanced water flux and separation capability, good resistance to organic fouling, and complete regenerability for fouling control. Additionally, the embedded zeolite nanoparticles are proved to be able to create fast pathways for water transport. Overall, this work provides a novel strategy to create zeolite-polymer composite membranes with enhanced separation performance and unique fouling mitigation properties.
