Interface colour scheme design is complex, but important. Most software allows users to choose the colours of single items individually and out of context, but does not acknowledge colour schemes or aid in their design. Creating colour schemes by picking individual colours can be time-consuming, error-prone, and frustrating, and the results are often mediocre, especially for those without colour design skills. Further, as colour harmony arises from the interactions between all of the coloured elements, anticipating the overall eff ect of changing the colour of any single element can be difficult. This research explores the feasibility of extending artistic colour harmony models to include factors pertinent to user interface design. An extended colour harmony model is proposed and used as the basis for an objective function that can algorithmically assess the colour relationships in an interface colour scheme. Its assessments have been found to agree well with human evaluations and have been used as part of a process to automatically create harmonious and usable interface colour schemes. A three stage process for the design of interface colour schemes is described. In the fi rst stage, the designer speci es, in broad terms and without requiring colour design expertise, colouring constraints such as grouping and distinguishability that are needed to ensure that the colouring of interface elements reflects their semantics. The second stage is an optimisation process that chooses colour relationships to satisfy the competing requirements of harmonious colour usage, any designer-specified constraints, and readability. It produces sets of coordinates that constitute abstract colour schemes: they de fine only relationships between coloured items, not real colours. In the third and fi nal stage, a user interactively maps an abstract scheme to one or more real colour schemes. The colours can be fi ne-tuned as a set (but not altered individually), to allow for such "soft" factors as personal, contextual and cultural considerations, while preserving the integrity of the design embodied in the abstract scheme. The colours in the displayed interface are updated continuously, so users can interactively explore a large number of colour schemes, all of which have readable text, distinguishable controls, and conform to the principles of colour harmony. Experimental trials using a proof-of-concept implementation called the Colour Harmoniser have been used to evaluate a method of holistic colour adjustment and the resulting colour schemes. The results indicate that the holistic controls are easy to understand and eff ective, and that the automatically produced colour schemes, prior to fi ne-tuning, are comparable in quality to many manually created schemes, and after fi ne-tuning, are generally better. By designing schemes that incorporate colouring constraints specifi ed by the user prior to scheme creation, and enabling the user to interactively fi ne-tune the schemes after creation, there is no need to specify or incorporate the subtle and not well understood factors that determine whether any particular set of colours is "suitable". Instead, the approach used produces broadly harmonious schemes, and defers to the developer in the choice of the fi nal colours.

Εκτός από τα Τεχνητά Νευρωνικά Δίκτυα, ένα άλλο παρεμφερές πρόβλημα είναι αυτό της μοντελοποίησης των δομικών και λειτουργικών χαρακτηριστικών διαφόρων τμημάτων του Κεντρικού Νευρικού Συστήματος καθώς και των διαφόρων εγκεφαλικών λειτουργιών. Στόχος αυτής της διπλωματικής είναι η δημιουργία ενός μοντέλου του φυσιολογικού νευρώνα και της συγκρότησης νευρωνικών δικτύων που εμπλέκονται σε κάποια εγκεφαλική λειτουργία. Στην ανάπτυξη του μοντέλου λήφθηκαν υπόψη τα ιδιαίτερα νευροανατομικά χαρακτηριστικά και νευροφυσιολογικά χαρακτηριαστικά και οι ιδιότητες που σχετίζονται με τις υπό μελέτη εγκεφαλικές καταστάσεις. Επίσης διερευνήθηκε η αλληλεπίδραση και η αναπτυσσόμενη δυναμική, τόσο σε κυτταρικό επίπεδο όσο και σε συστημικό επίπεδο, καθώς και η δυναμική αλληλεπίδραση νευρωνικών δικτύων. Πραγματοποιήθηκε μακροσκοπική προσέγγιση με τη χρήση μαθηματικών μοντέλων και αναπτύχθηκε ένα GUI περιβάλλον για τη διαχείριση του προγράμματος από το χρήστη. / Apart from the Artificial Neural Networks, another similar problem is the modeling of structural and functional characteristics of different parts of the Central Nervous System and the various brain functions.

UML was proposed as the standard language for modeling. The user interface is an important part of the software and has a fundamental importance to improve its usability. Unfortunately the standard UML does not offer appropriate resources to model user interfaces. Some proposals have already been proposed to solve this problem: some authors have been using models in the development of interfaces (Model Based Development) and some proposals to extend UML have been elaborated. But none of them considers the theoretical perspective presented by the semiotic engineering, that considers that, through the system, the designer should be able to communicate to the user what he can do, and how to use the system itself. This work presents Visual IMML, an UML Profile that emphasizes the aspects of the semiotic engineering. This Profile is based on IMML, that is a declarative textual language. The Visual IMML is a proposal that aims to improve the specification process by using a visual modeling (using diagrams) language. It proposes a new set of modeling elements (stereotypes) specifically designed to the specification and documentation of user interfaces, considering the aspects of communication, interaction and functionality in an integrated manner / Os processos de desenvolvimento de software proposto pelas abordagens mais recentes da Engenharia de Software utilizam modelos e a UML foi proposta como a linguagem padr?o para a modelagem.

AMPLO is a design environment of digital systems which is composed of an object oriented data base and of several design tools, such as text editors, graphics editors, compilers and simulators of digital systems LAGO is the high-level interface of AMPLO, and it is responsible for controlling the access to the system's resources. With this interface, the users of AMPLO may activate administratation and, design management functions, data base queries, and design tasks. The access to the several system functions is in accordance to the user classification. A "general administrator" is responsible for creating users and groups of users. Groups of users create designs, under the leadership of a "group administrator", who is indicated by the general administrator when the group is created. The "grou p administrator" has private functions for managing the group and the data base associated to the group. Designers activate design tools as text editors, graphic editors, compilers and simulators. Also they can use task management functions (a task corresponds to a long transaction at the data base level, like the creation of objects in several editing sessions, for example). A temporary data base which is a designer private data base is associated to each task, and is removed at the end of the task. Thus, the data base of AMPLO is divided into three levels: p ublic data base, group data base and designer data base LAGO permanently, offers facilities of data base ueries. These q uery functions are available when the user inicializes the system and later on, when the query function is selected. The navigation through the data base objects can be done in a gra p hical or textual form. In the graphical form, the objects are presented by trees representing the several types of relationships. In the textual form, LAGO presents lists with the name of objects.

In the past decade, the design and manufacturing of intelligent multipurpose underwater vehicles has increased significantly. In the wide range of studies conducted in this field, the flexibility and autonomy of these devices with respect to their intended performance had been widely investigated. This work is related to the design and manufacturing of a small and lightweight autonomous underwater vehicle (AUV) with vision capabilities allowing detecting and contouring obstacles. It is indeed an exciting challenge to build a small and light submarine AUV, while making tradeoffs between performance and minimum available space as well as energy consumption. In fact, due to the ever-increasing in equipment complexity and performance, designers of AUVs are facing the issues of limited size and energy consumption. By using a pair of thrusters capable to rotate 360o on their axis and implementing a mass shifter with a control loop inside the vehicle, this later can efficiently adapt its depth and direction with minimal energy consumption. A prototype was fabricated and successfully tested in real operating conditions (in both pool and ocean). It includes the design and embedding of accurate custom multi-purpose sensors for multi-task operation as well as an enhanced coordinated system between a high-speed processor and accustomed electrical/mechanical parts of the vehicle, to allow automatic controlling its movements. Furthermore, an efficient tracking system was implemented to automatically detect and bypass obstacles. Then, fuzzy-based controllers were coupled to the main AUV processor system to provide the best commands to safely get around obstacles with minimum energy consumption. The fabricated prototype was able to work for a period of three hours with object tracking options and five hours in a safe environment, at a speed of 0.6 m/s at a depth of 8 m.

This report describes an approach of creating a system identifying fruit and vegetables in the retail market using images captured with a video camera at- tached to the system. The system helps the customers to label desired fruits and vegetables with a price according to its weight. The purpose of the sys- tem is to minimize the number of human computer interactions, speed up the identification process and improve the usability of the graphical user interface compared to existing systems. To accomplish creating a system improving these properties, an idea of implementing machine learning to identify the products aroused. Instead of assigning the responsibility to the user, who usually iden- tify the products manually, the responsibility is given to a computer. To classify an object, different convolutional neural networks have been tested and retrained. The networks have been retrained on data sets collected from ImageNet. To improve the accuracy, the networks have also been retrained on images where the background environment is similar to the environment the networks are supposed to perform in. The networks tested in this report are MobileNet and Inception. The networks have different propagation time and varies in accuracy. MobileNet performs the classification about seven times faster than Inception, but Inception gives more accurate results. To improve the systems further, usability testing has been performed on the graphical user interface of existing system and resulted system. To test the usability, a heuristic evaluation has been performed in combination of a second test produced by the authors. The tests concluded that the resulted system was more user friendly compared to existing systems. The hardware of the system constitutes of a Raspberry Pi, camera, display, load cell and a case. The software includes Python-code to label an image, a graphical user interface to interact with the user and a server created with Node.js. The graphical user interface has been programmed with JavaScript supplemented with the React library. To conclude, implementing convolutional neural networks to classify images and developing a new user interface resulted in a faster identification process together with fewer usability flaws.
