description: Ports and their stakeholders are highly interconnected within dynamic maritime supply chains.
 Managing these networks has led to an increasing dependence on information and communication technologies (ICT), opening
 up the sector to new vulnerabilities from cyber-risks. Cyber risk management is currently a major challenge for the maritime
 sector. Maritime information systems are often built with off-the-shelf components, which in many cases are designed without
 considering the cyber risks that these introduce to the wider system. Training has long formed part of the maritime sector’s
 risk management approach. Much of the current cybersecurity legislation explicitly mentions training as a way to help secure
 the maritime sector’s digital infrastructure. As ports form the nexus between land and sea it is crucial that they prioritize
 cybersecurity training as a risk management strategy to ensure the continued security of maritime information systems. This
 paper will demonstrate, using the EU Cyber-MAR platform, the disruption caused by a spear-phishing attack targeting a port’s
 power management network. The paper will discuss the financial implications that this attack, and larger-scale cyber-incidents,
 could have at a corporate level (reputation, contracts, fines), as well as at an EU level (large scale disruption).

An investigation of the factors affecting students' acceptance and intention to use e-learning systems at Kuwait University: developing a technology acceptance model in e-learning environments
Creators: name: Alkandari, Badriah
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Digital electronic devices

description: The current study has aimed to investigate the factors affecting students’ acceptance and intentions to use e-learning systems in higher education in Kuwait, based on the Technology Acceptance Model (TAM1). A theoretical model was proposed to study the effect of the following external factors: Internet self-efficacy, personal innovativeness, technical support, instructor characteristics, course interactivity and content quality. The study hypotheses were examined using a mixed method that comprised a questionnaire – a cross sectional survey and semi-structured interview. The data were collected from 336 undergraduate students registered on courses incorporating VLEs, particularly Blackboard, at Kuwait University. The study results provided support for relationships between the TAM Model constructs via two methods, where quantitative and qualitative results indicated that perceived ease of use and perceived usefulness were considered to be key factors in explaining students’ attitudes toward VLEs. Nonetheless, perceived usefulness was a more influential factor than perceived ease of use in terms of students’ attitudes and was also a higher predictor of attitudes toward using VLEs. Furthermore, the results indicated that perceived usefulness and students’ attitudes had a significant effect on the intention to use e-learning in the future. However, students’ attitudes were more strongly influenced than perceived usefulness as regards the intention to use e-learning. Furthermore, the results show that the students’ intentions to use e-learning were positively correlated with their overall attitude toward elearning. Regarding the effect of external factors, the study results reveal that personal innovativeness, instructor characteristics, course interactivity and content quality positively affected perceived usefulness. On the other hand, all external factors also had a positive effect on perceived ease of use. Furthermore, the study results show that perceived ease of use was found to be the strongest predictor of perceived usefulness, and self-efficacy was the most critical external factor influencing students’ perceived ease of use of VLEs.

description: It has been reported that clustered miRNAs can be transcribed coordinately and exhibit similar functions by regulating the same targets. miR-1/133a and miR-206/133b are well-characterized miRNA clusters. However, the effect of these clusters on EGFR-TKI resistance is not clear. In this study, we demonstrated that lentivirus-mediated HGF overexpression was able to induce gefitinib resistance in non-small cell lung cancers with EGFR sensitive mutations. miR-1/133a and miR-206/133b clusters could overcome HGF induced gefitinib resistance. Furthermore, the clusters were more effective than individual miRNA. Transcriptome RNA sequencing and bioinformatics analysis revealed that multiple pathways, including ‘EGFR tyrosine kinase inhibitor resistance’ pathway, were involved in anti-resistance mechanisms of miR-1/133a and miR-206/133b clusters. Western blotting results confirmed the inhibitory effect of miRNA clusters on MET expression and downstream pathway activation. In conclusion, miR-1/133a and miR-206/133b clusters are able to exhibit the synergetic effect on overcoming HGF-induced gefitinib resistance in NSCLC and the mechanisms are through targeting multiple genes related to gefitinib resistance.

description: This study presents the four years’ seasonal baseline hydrological condition of a proposed low impact development neighbourhood in Brantford, Ontario. A comprehensive monitoring scheme including on-site infiltration tests, topographic survey, and instream and groundwater monitoring was conducted on the site and in the adjacent Whitemans Creek and Lewis Drain. The streams’ high flows and storm responses are not included in the current study due to limited accessibility. Results show that sandy soil with a high infiltration rate on the site infiltrates the majority of the precipitation and supports the installation of permeable pavements. Surface water and groundwater interaction was observed at the Municipal Drain. Throughout the summer, the Creek has clear flow conditions for the majority of the time and baseflow accounts for a large proportion of flows in the Creek. During the monitoring period, water quality parameters in the Creek satisfied the CCME guidelines for the protection of aquatic life. The use of permeable pavements on the site will help to maintain pre-development water balance. As neighbourhood-level LID is rarely directly demonstrated, we encourage further investigations once the site has been developed.

Angels at the National and Bohemians in the West End: transposing and reviving American dramatic depictions of AIDS to the British stage in Angels in America and Rent
Creators: name: Garside, Emily
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Drama, theatre and performance studies

description: This study focuses on two highly successful AIDS plays, Tony Kushner’s Angels in America and Jonathan Larson’s Rent. These plays were performed in London in 1994 and 1998 respectively and revived in 2007. Both plays are key examples of American theatrical representations of AIDS performed on the London stage. This thesis examines how these plays represented AIDs on the London stage. Secondly the reception of these American AIDS plays is considered when staged in London is considered. Finally the longer term significance of performing these texts, both in terms of depictions of AIDS and the wider stylistic elements in relation to the theatrical landscape is also examined. Through reflection on the reception of these plays, they are considered for their significance of their depiction of AIDS and place within London theatre. It is examined how, through the use of political, medical and emotional ties, these plays successfully depicted AIDS when transposed to the British stage. In these successful depictions of AIDS, and in their overall press reception, these plays developed a significant place in the London theatrical landscape. Using archival records and press responses, the performance of these plays in their original production and in revival is considered in relation to the original productions and the revived versions in London. The consideration of live, performed versions of these texts is of central importance, and further theoretical consideration is built around the nature of a performance text. In using archival records, elements of the productions and performance are considered in a manner that is not possible if only using the published, written version of the play. These plays are considered as significant works on AIDS that transposed successfully to the London theatrical landscape, making Angels and Rent not only but successful and important parts of the British theatrical landscape.

description: BACKGROUND AND AIMS: Online questionnaires completed by participants are often used in eczema clinical trials to capture the views of participants about their eczema. This allows researchers to measure the effectiveness of different treatments. Findings of some eczema RCTs showed an improvement in eczema severity scores in both groups in the absence of an intervention effect. This could have occurred as a result of general trial effects or might have been due to the impact of completing questionnaires regularly (known as monitoring) that might caused a change in the way people manage their eczema. This is a concern within clinical trials because completing regular questionnaires may make it harder to identify changes in the eczema resulting from the treatments being tested. Currently, there is a lack of understanding around the impact of regular monitoring of disease activity on trial outcomes in eczema and further research is needed. This methodological trial is designed to investigate whether completing questionnaires is an effective intervention in improving eczema severity. The overall aim of this study is to inform the design of future eczema randomised controlled trials on whether regular monitoring of eczema symptoms affects patient-reported outcomes.
ETHICAL APPROVAL: Favourable ethics opinion to conduct this study was given by the Faculty of Medicine and Health Science Research Ethics Committee, University of Nottingham (Ref. number: 239- 0421).
TRIAL REGISTRATION: The EMO trial has been prospectively registered on the ISRCTN registry on 29th June 2021 (ISRCTN45167024).
title: Social Circulation and Historical Culture: A Shakespeare Myth in Sevenoaks
Creators: name: Hails, Charlotte
Publisher: name: University of Kent
Year: 2014

description: This thesis explores a provincial myth in the context of local historical culture and with reference to what Daniel Woolf has called ‘the social circulation of the past’. The myth identifies Sevenoaks School as a ‘grammar school’ cited by Jack Cade in Shakespeare’s Henry VI Part 2. The thesis examines the processes by which the myth developed, focussing on elements of the myth and on several central texts: Lambarde’s A Perambulation of Kent; Henry VI Part 2; a handwritten local history; and Jack Cade in Victorian adventure fiction for boys. In discussing the interaction of print and oral culture, the thesis argues for a revised understanding of Lambarde’s work on Sevenoaks and illustrates how some elements of this local historical culture remained unrecorded, outside formal history writing, until the nineteenth century. It also proposes a new understanding of the school’s wider reputation in the early modern period, with reference to previously unexamined evidence of boarding scholars. The thesis concludes that the myth evolved from the early modern social circulation of the past in print and oral culture, custom, memory and landscape, and that it flourished in the early twentieth century in a historical culture infused with the ‘cult’ of Shakespeare and the rural, romantic nostalgia of ‘Englishness’ expressed in the arts and literature of the time.

title: Forecasting the outcome of Greek football games using mathematical models and power rankings
Creators: name: Παλιατσα Δημητρα
Publisher: name: Technical University of Crete
Year: 2014

description: The subject of this thesis is the prediction of the results of football matches and the estimation of the final points gathered by the teams at the end of the football year. In particular, we are interested in the prediction of the outcome of the Greek Superleague games for the season 2007-2008 to 2013-2014. For this purpose it was necessary to record the relevant data for all teams after each game (goal difference, current points, number of wins, number of draws, number of defeats, etc.). Then, using the data gathered and utilizing various techniques we try to predict the final outcome of the matches. Our first approach falls into the sport rating systems category, where we rank all the teams based on their power scores (power ranking procedure). Our second approach is based on clustering and is implemented using the k-means algorithm. In the third approach we use two independent Poisson distributions for describing the goals scored by the home and the away team, respectively. Moreover, we use two naive methods for extracting baseline results: in the first we assume that the home team is always the winner and in the second we assume that the last year's result will be repeated for all teams that compete in two consecutive years. Finally, we use the moving average, the weighted moving average and the exponentially weighted moving average to estimate the final points that each Superleague team will gather at the end of the football year. The results of our study are promising, demonstrating the usefulness of the proposed models and making the further study of this problem interesting for future improvements.
title: Maximally sparse convex estimation and equalization
Creators: name: Λουρακης Γεωργιος
Publisher: name: Technical University of Crete
Year: 2014

description: Sparse multipath channels are wireless links commonly found in communication systems such as  High Frequency radio channels, horizontal and vertical underwater acoustic channels and terrestrial broadcasting channels for High Definition Television. Their impulse responses are characterized by a few significant terms that are widely separated in time. With high speed transmission, the length of a sampled sparse channel can reach hundreds of symbol interval. Thus, the amount of Intersymbol Interference (ISI) at the receiver is very high. Consequently, the presence of an ISI mitigating structure at the receiver, such as the Decision Feedback Equalizer (DFE) is essential. Due to the sparse impulse responses of these channels, traditional estimation techniques such as Least Squares (LS) result in over-parameterization and thus poor performance of the estimator. Also, classical equalizers become too complex for tackling these channels. The problem of estimating and equalizing sparse multipath channels is considered in this thesis. We formulate the sparse channel estimation and the computation of the sparse DFE filters as sparse approximation problems. A usual approach in sparse approximation problems is regularization with an l_1 norm penalty term and usage of convex optimization techniques in order to acquire a solution. Other sparsity promoting penalty functions are available, but the l_1 norm has the advantage to be a convex function, making the l_1 norm regularized approximation problem a convex one. When a problem is formulated as a convex optimization problem, it can be solved by very fast, efficient and reliable algorithms. In order to achieve sparser solutions and still gain from the benefits of the convex optimization theory, the Maximally Sparse Convex (MSC) algorithm utilizes a non-convex regularization term, that promotes sparsity more strongly than the l_1 norm, but chosen such that the total cost function remains convex.

description: The development of high-level behavior for autonomous robots is a time-consuming task even for experts. The Kouretes Statechart Editor (KSE) is a Computer-Aided Software Engineering (CASE) tool, which allows to easily specify a desired robot behavior as a statechart model utilizing a variety of base robot functionalities (vision, localization, locomotion, motion skills, communication) developed within the Monas robotic software architecture framework. This thesis presents an extension to KSE, which allows to define generic agent behaviors using automatic framework-independent code generation, as long as the underlying software framework is written in the C++ programming language. This way a user can program behaviors for physical robots or software agents that can be executed on any platform using any C++ software framework. This thesis demonstrates the transparent use of the extended KSE in the SimSpark 3D soccer simulation, the Wumpus world, and the Starcraft Broodwar strategy game.
title: Implementation of Frequency Division Multiple Access Digital Backscatter Sensor Network
Creators: name: Τουντας Κωνσταντινος
Publisher: name: Technical University of Crete
Year: 2014

description: Environmental sensing applications require dense sensor deployments for precise monitoring of each plants' micro-climate; For such applications, scatter radio is a promising communication and networking technology. Since modulation is achieved by means of reflection, very low-cost and low-power RF front-ends and sensor nodes can be constructed. However, such technology has demonstrated limited range in commercial scatter radio applications, like radio frequency identification (RFID) systems. In order to alleviate that problem, the bistatic architecture has been proposed, where emitter of illuminating carrier towards the tag/sensor and reader of the modulated reflection (from tag/sensor) are dislocated. Also, frequency shift keying (FSK) modulation has been utilized for simultaneous transmission of many scatter radio sensors, through frequency division multiple access (FDMA). These schemes allow the creation of a scatter sensor network, using flexible topologies with multiple emitters and a single reader, increasing the probability for short emitter-to-tag/sensor distances. This work experimentally demonstrates the creation of such scatter radio network with low-cost 8051 micro-controller units (MCU), where sensed information is converted to digital messages using the internals analog-to-digital (ADC) converters. Furthermore, implementation of short-block length channel encoding based on Reed-Muller codes are tested experimentally. This work is a small step towards the realization of large-scale, scatter radio sensor networks.
title: Study of low frequency noise in High Voltage MOS transistor
Creators: name: Φελλας Κωνσταντινος
Publisher: name: Technical University of Crete
Year: 2014

description: HVMOSFETs find many different applications such as switching applications, input-output operations, voltage conversions, RF amplification etc. The effect of drift region on 1/f noise remained unclear until recently due to the difficulty of performing 1/f noise measurements under high drain voltages, on the order of tens of Volt. This is mainly due to the lack of adequate measurement equipment, which usually restricts low frequency noise to be measured up to just a few Volt, usually generated from batteries.

A 1/f noise parameter extraction method for high-voltage (HV-)MOSFETs at 3V drain  bias is presented in this thesis. In this region the overall noise is mostly dominated by the noise originating in the channel. The bias dependence of flicker noise, related to transconductance-to-current ratio, allows for an easy means to determine related noise parameters. Though measured data is limited, parameters related to carrier number fluctuation effect may be found. 50 V N and P-channel HV-MOSFETs are investigated for long as well as short channel lengths. The parameter extraction method is applied to a recently established 1/f noise model for HV-MOSFETs, showing a good agreement among model and experimental data.
Leveraging public untargeted metabolomics data to propagate structurally related molecule annotations to millions of MS/MS spectra
Creators: name: Bittremieux, Wout
Publisher: name: Zenodo
Year: 2022

description: One of the key goals of untargeted tandem mass spectrometry (MS/MS) metabolomics is discovering biologically relevant molecules. Currently there is still a lot of discovery potential: using spectral library searching, on average only ~5% of the data can be annotated. This means that the vast majority of data that are collected do not yield any biological insights. I will present a strategy to identify molecules that are structurally related to previously known reference molecules using repository-scale molecular networking. Based on spectral similarity, information can be propagated to neighboring MS/MS spectra in a molecular network to increase the spectrum annotation rate. We have propagated annotations from molecular networks associated with 521 million MS/MS spectra from 1335 compatible untargeted metabolomics datasets in various metabolomics data repositories, including GNPS/MassIVE, Metabolights, and Metabolomics Workbench, to create the GNPS nearest neighbor suspect spectral library. It consists of 87,916 novel reference spectra corresponding to modified molecules that are structurally related to known reference molecules. Repository-scale molecular networking to create the suspect library revealed 1350 common modification mass differences, which provide chemical insights into the processes that molecules undergo in vivo and during mass spectrometry analysis. Using the suspect library for spectral library searching increases the spectrum annotation rate 2-fold on average, considerably boosting the interpretation rate of untargeted metabolomics beyond the state of the art. To demonstrate the performance of the suspect library, suspect annotations enabled the discovery of hundreds of acylcarnitines, including significant acylcarnitine signatures for Alzheimer's disease patients, providing biomedically relevant insights into changes in energy metabolism; as well as for natural products drug discovery. The nearest neighbor suspect spectral library is freely available with an open license on GNPS for community spectral library searching, where it can be used to provide novel hypotheses for previously unexplored untargeted metabolomics data.

Επιπρόσθετα χρησιμοποιήθηκε η μέθοδος Δυναμικής Σκέδασης Φωτός (DLS) για να προσδιοριστεί η επίδραση της IS στην ετεροσυσσωμάτωση των νανοσωματιδίων του GO και των κολλοειδών KGa-1b. Οι ενέργειες αλληλεπίδρασης μεταξύ των δύο σωματιδίων, για όλες τις πειραματικές συνθήκες υπολογίστηκαν χρησιμοποιώντας τις μετρημένες τιμές του ζ δυναμικού και εφαρμόζοντας την κλασική θεωρία DLVO. Στη συνέχεια έγιναν πειράματα ροής σε στήλη κορεσμένη με νερό, πληρωμένη με γυάλινα σφαιρίδια και χαλαζιακή άμμο, με σκοπό να προσδιοριστούν τα χαρακτηριστικά της μεταφοράς του GO και του KGa-1b ξεχωριστά αλλά και τα χαρακτηριστικά της συμμεταφοράς του GO με το KGa-1b, υπό διάφορες υδατικές συνθήκες (pH=4, 7, 10 και IS=7, 12, 27 mM). Επίσης υπολογίσθηκαν οι αποδόσεις των συγκρούσεων χρησιμοποιώντας την κλασσική θεωρία διήθησης. Και εδώ τα ενεργειακά προφίλ αλληλεπίδρασης μεταξύ του GO ή του ΚGa-1b με τα γυάλινα σφαιρίδια ή την χαλαζιακή άμμο υπολογίστηκαν χρησιμοποιώντας τις μετρημένες τιμές του ζ δυναμικού και εφαρμόζοντας την κλασική θεωρία DLVO.

description: The objective of this scoping review is to map the evidence concerning survey questions about the intended timing of retirement used in the work-retirement literature to predict actual retirement timing of older workers. One example for such a question is: ‘Have you decided at what age you will quit work and retire? If yes, at what age? (full years)’ (Solem et al., 2016). We want to extract the survey questions from each study to establish commonalities and differences across the studies in terms of the concepts they measure and populations among which they have been used as well as collect, present and discuss the predictive power of these survey questions for the timing of actual retirement. Differences by country, time period and age are to be expected. With that we want to give directions for future research, organizations and national policy.

description: Αντικείμενο της παρούσας διπλωματικής εργασίας αποτελεί η μελέτη του βιοκλιματικού σχεδιασμού, εστιάζοντας στις επιφανειακές θερμοκρασίες των δομικών υλικών (δρόμοι – πεζοδρόμια – επιφάνειες κτηρίων) και τον τρόπο που επιδρούν στη διαμόρφωση του αστικού μικροκλίματος και στη θερμική άνεση, καθώς και η προσομοίωση των μικροκλιματικών συνθηκών σε ένα ελεύθερο και διαδεδομένο πρόγραμμα υπολογιστικής ρευστομηχανικής, το ENVI-met.
Ως χώρος εφαρμογής επιλέχθηκε η πλατεία Ομόνοιας στο κέντρο της Αθήνας και η μελέτη επικεντρώνεται στη σύγκριση των αποτελεσμάτων (προσομοίωσης της περιοχής) επιφανειακής θερμοκρασίας του προγράμματος, με τις πραγματικές θερμοκρασίες των επιφανειών στους δρόμους και στα πεζοδρόμια, οι οποίες καταγράφηκαν με θερμοκάμερα, συγκεκριμένες μέρες και ώρες των θερινών μηνών. Παράλληλα κατασκευάστηκε το μοντέλο της πλατείας στο Envi-met και επιλύθηκε για την ημέρα των μετρήσεων που αντιπροσώπευε μία μέση καλοκαιρινή ημέρα στο κέντρο της Αθήνας. Τα αποτελέσματα της προσομοίωσης οπτικοποιήθηκαν επίσης, μέσω του προγράμματος Leonardo το οποίο συμπεριλαμβάνεται στο Envi-met.
Στόχος της εργασίας είναι ο έλεγχος της αξιοπιστίας των αποτελεσμάτων αυτών του ENVI-met και η αναλυτική παρουσίαση των τιμών της επιφανειακής θερμοκρασίας της περιοχής για μία τυπική καλοκαιρινή μέρα καθώς και των παραγόντων που την καθορίζουν.

description: For roughly three decades, workplace bullying intervention research has struggled to design and implement interventions that effectively address and prevent the behaviour. Therefore, the purpose of this thesis was to explore this lack of effectiveness and identify ways to improve workplace bullying intervention success. Readiness was identified as a key concept that is widely posited as crucial for change success in other realms of literature but has not yet been considered in workplace bullying intervention research. A conceptual model and process framework depicting readiness for change in a bullying context was initially proposed. Using Template Analysis, a two-stage, modified Delphi study, Confirmatory Factor Analysis and Pearson’s Bivariate Correlation, the proposed conceptual model and its relationship with outcome variables was confirmed. Results indicated readiness for workplace bullying consists of two-factors: structural readiness and psychological readiness, and that these are underpinned by nine, sub-components. High levels of readiness were also confirmed to have an influence on higher levels of perceived intervention success and employee engagement in and support for prospective workplace bullying interventions. A readiness for workplace bullying interventions assessment tool was also designed, developed, and validated through this research. Results of validation studies confirmed the tool to be a valid and reliable instrument with a robust factorial structure and high internal construct validity. The key limitations of this research are that the model does not account for the role emotion, or previous experiences of workplace change has on employee perceptions of readiness and is not assessing individual readiness for change but rather, their perceptions of the organisations readiness to change. Despite these, this thesis has significantly advanced research and practice around workplace bullying interventions by providing scholars with a comprehensive understanding of what constitutes readiness for a workplace bullying intervention, alongside how this influences behavioural outcomes amongst employees regarding the change. For practitioners and organisations, this research has also created an accessible and efficient assessment tool, that can be used to measure levels of readiness, in order to establish context-intervention fit (the appropriateness of an intervention in its setting) and derailment risk for a workplace bullying intervention. To the researcher’s knowledge, this is the first study in the field to conceptualise readiness for change to a workplace bullying context and in doing so, has helped amass potential for future research to develop workplace bullying interventions that effectively prevent and address the behaviour in the long-term.

description: Η παρούσα ΔΕ έχει σαν στόχο τη μελέτη για την αναβάθμιση του κτιρίου της φοιτητικής εστίας του Πολυτεχνείου Κρήτης με σκοπό όχι μόνο την εξοικονόμηση ενέργειας, αλλά και τη βελτίωση των συνθηκών διαβίωσης των ενοίκων.
Αρχικά πραγματοποιήθηκε διερεύνηση της παρούσας ενεργειακής κατάστασης της εστίας με τη συλλογή των καταγεγραμμένων πληροφοριών από τις πραγματικές καταναλώσεις. Επίσης ταυτόχρονα διεξάχθηκε μια έρευνα μέσω ερωτηματολογίου ώστε να συνυπολογιστεί η άποψη και η εμπειρία των ενοίκων για την παρούσα κατάσταση της εστίας αλλά και για να συλλέγουν πληροφορίες που αφορούν τις συνήθειες και τις απόψεις των ενοίκων πάνω στον τομέα αυτόν.
Από τη διαδικασία του ερωτηματολογίου έγινε η στατιστική ανάλυση και ομαδοποίηση των αποτελεσμάτων. Σκοπός ήταν την απεικόνιση της γενικής Εικόνας της παρούσας κατάστασης ώστε να γίνουν οι κατάλληλες παρεμβάσεις στοχευμένα, στα κρισιμότερα τμήματα που πάσχει το κτίριο. Επίσης επιχειρήθηκαν κάποιες συσχετίσεις μεταξύ μεταβλητών για να διαπιστωθεί τυχόν αλληλεξάρτηση ώστε να εκμεταλλευτεί μελλοντικά σε τυχόν παρεμβάσεις.
Σκοπός της μελέτης ήταν να εξεταστούν πιθανά σενάρια που μπορούν να εφαρμοστούν στο παρόν κτίριο ώστε να επιτευχθεί μείωση των ενεργειακών αναγκών αλλά ταυτόχρονα και βελτίωση των συνθηκών διαβίωσης των φοιτητών. Ο στόχος για την ενεργειακή εξοικονόμηση στο κτίριο ήταν να προσεγγίσει ένα κτίριο σχεδόν μηδενικής ενέργειας. Για την επίτευξη αυτού του στόχου ήταν αναγκαία επίσης η αυτοπαραγωγή ενέργειας επί του κτιρίου μέσω ανανεώσιμων πηγών ενέργειας. Βέλτιστο σύστημα παραγωγής ενέργειας για τη συγκεκριμένη περίπτωση κρίθηκαν τα φωτοβολταϊκά πλαίσια. Έτσι, αρχικά εξετάστηκαν τέσσερα διαφορετικά σενάρια εξοικονόμησης και ένα συνδυαστικό όλων των σεναρίων μαζί και στη συνέχεια, αφού επιλέχθηκε το βέλτιστο, σχεδιάστηκαν τρία διαφορετικά σενάρια αυτοπαραγωγής ενέργειας. Το βέλτιστο και προτεινόμενο σενάριο ήταν το συνδυαστικό το οποίο επιτυγχάνει 36% μείωση των ενεργειακών απαιτήσεων όπου η επένδυση για τις μετατροπές και αλλαγές που θα πρέπει να γίνουν έχει μακροπρόθεσμο χρόνο αποπληρωμής που αγγίζει τα 20 έτη. Τέλος το σενάριο αυτοπαραγωγής που προτείνεται ως βέλτιστο είναι για την κάλυψη του 62% των αναγκών του κτιρίου όπου επιτυγχάνει τη μέγιστη εκμετάλλευση του διαθέσιμου χώρου με βέλτιστη ενσωμάτωση.

Subjects: Aquíferos. Uso e Ocupação do Solo. Contaminação. Poluição

description: Em tempos de escassez hídrica e previsões nada positivas a respeito da continuidade dos recursos naturais, principalmente com respeito à disponibilidade de água potável, os aquíferos surgem como uma alternativa para a salvação da população. Porém, é necessário gerir e proteger estes recursos, visto que o uso e ocupação dos solos em muitos dos casos impactam diretamente a qualidade destas águas. As diferentes atividades humanas na superfície acabam por gerar resíduos e rejeitos tóxicos que, uma vez despejados no ambiente podem gerar consequências bem prejudiciais. Este trabalho vem para apresentar ao leitor uma visão sistemática sobre os aquíferos e alguns dos usos do solo que podem impactar nas águas subterrâneas. Vale ressaltar, porém, que este trabalho é uma apresentação desta problemática e que pode e deverá ser consultado e melhorado sempre que necessário.

description: Τα επιστημονικά επιτεύγματα των Τεχνολογιών της Πληροφορικής και των Επικοινωνιών («ΤΠΕ») εξελίσσονται με γοργούς ρυθμούς στην διαρκώς αναπτυσσόμενη Κοινωνία της Πληροφορίας, επιφέροντας αναταράξεις, τόσο στο επιχειρηματικό «γίγνεσθαι», όσο και στην καθημερινότητα πλείστων όσων ανθρώπων. Για την πιο ομαλή υιοθέτηση των πρακτικών της 4ης Βιομηχανικής Επανάστασης, αλλά και για να ρυθμιστούν αποτελεσματικά πλείστα όσα ζητήματα ενδεχομένως ανακύψουν σε συμβατικό επίπεδο, το δίκαιο, η νομική επιστήμη και οι ΤΠΕ πρέπει να παράσχουν τα κατάλληλα εχέγγυα, δημιουργώντας ένα υπόβαθρο αμοιβαίας εμπιστοσύνης μεταξύ των μερών. Καθίσταται, συνεπώς, εναργές, ότι το «κλίμα αλλαγής» το οποίο παρατηρείται στο πλαίσιο της «ψηφιακής σύγκλισης», που ξεκίνησε τα τελευταία έτη να αναδύεται σε ενωσιακό και συνακόλουθα εθνικό επίπεδο, πρέπει να αποτυπωθεί όσο το δυνατόν αναλυτικότερα και στις συμβάσεις πληροφορικής, οι οποίες δέον να διέπονται από κοινούς κανόνες, απομακρύνοντας τοιουτοτρόπως την ανάδυση «γκρίζων» ζωνών και κενών δικαίου. Στο πλαίσιο της παρούσας μελέτης θα αναλυθούν συγκεκριμένες συμβάσεις πληροφορικής, που διακρίνονται για το νεωτεριστικό τους χαρακτήρα, και οι οποίες στο εγγύς μέλλον θα απασχολήσουν σε ακόμα εντονότερο βαθμό όσους ασχολούνται με την επίλυση σύνθετων ζητημάτων Νομικής Πληροφορικής. Ειδικότερα, αντικείμενο επιστημονικής διερεύνησης θα αποτελέσουν οι συμβάσεις λογισμικού με ειδική αναφορά στο λογισμικό Τεχνητής Νοημοσύνης και στην Οδηγία 2019/770, που πιθανότατα θα πρωταγωνιστήσουν στο πλαίσιο της ψηφιακής μετάβασης, οι συμβάσεις νεφουπολογιστικής, ενόψει μάλιστα και της προαναγγελίας κατασκευής πολυάριθμων data centers και το καθεστώς αδειοδότησης του λογισμικού ανοιχτού κώδικα, δεδομένης της αναντίρρητης συμβολής του στη διάδοση της γνώσης.
