Abstract:
Since the beginning of the country's history, Saudi Arabia has dramatically transformed every aspect of its existence from its booming economy to the massive expansion of educational offerings. But this natural resource and tradition rich nation is now faced with a cultural revolution that is not unfamiliar in the history of mankind yet is exceptionally unique to modern society. In a time when almost all countries in the world have recognized women to be an essential part of civil society, the kingdom is just beginning to turn its attention to the inequality women experience there. In light of this paradigm shift in the way women are viewed in Saudi Arabia, education is at the forefront illustrating evident signs of this change. With the support of the king and powerful political leaders universities are opening their doors to female engineers and companies are starting to employ more and more females outside the realm of education. With such momentum building it is an auspicious moment to further stretch the boundaries and reach for a wider audience including younger females in secondary school. This project introduces a comprehensive program for the enrollment of secondary school female students in a program constructed around the hope to encourage girls to consider engineering as a topic of study at higher education institutions. The program embodies the idea of learning, applying, creating and engineering (LACE) where students will take an intensive engineering course (IEC) hosted by universities outside of KSA and a project course at their local secondary school to apply what they learned through the creation and engineering of a solution that address issues challenging their communities.

Abstract:
This study explores what motivates engineers in their early-mid career to change careers. It first establishes the definition of a career change from the perspective of those who have changed careers, and then examines what drives, influences and facilitates a career change, as well as how a career change is enacted physically and emotionally. This has been looked at through the contemporary lens of the ‘intelligent career framework’. This research adopted a qualitative, abductive approach following an initial inductive small-scale exploratory study. The fieldwork consisted of a pilot and main study using semi-structured interviews. For the main study, 22 interviews were conducted within one organisation in order to elicit the subjective experiences of engineers who had undertaken a career change. The findings show how the driving factors relate predominantly to knowing-why and knowing-where. The influencing and facilitating factors vary by individual, and relate to knowing-what, knowing-how knowing-when and knowing-whom. Six clusters of interacting factors were observed with knowing-why, knowing-how and knowing-when at the core. Whilst the process of career change was complex and long, differing pathways through which individuals changed careers were evident, as well as emotions that needed to be managed. This study contributes to knowledge in the area of contemporary career theory by exploring career change through a new lens: the intelligent career framework. It demonstrates how individuals use their ‘career capital’ to effect a career change and the ways in which the six knowings interact to bring about a career change. It extends the understanding of the process of career change and discovers some of the organisational factors that influence or facilitate individuals making a career change. All of these contributions address identifiable gaps in the literature.

Abstract:
The issue of women in engineering, or the relative lack thereof, has been a frequently discussed and reported topic for the past eighty years working groups, government groups and organisations have commented on the lack of women interested in engineering and how this should be addressed. During this time however, one aspect of females in engineering has been regularly overlooked, that engineering is not devoid of females, every year females take up places on engineering courses at university, representing, on average 14% of the undergraduate engineers. As such, perhaps the question to be asked is not why there are so few females in engineering but why, if it is so unattractive to females, are 14% of higher education engineering places taken by women? This research views the issue of females in engineering from this, more positive, stance. It aims to determine any similarities amongst the females who do choose to study engineering in order that these similarities, if any, may be exploited and used to inform initiatives aiming to increase the number of females following an engineering career path.

Abstract:
In an age of rapid global change the roles that engineers fulfil are also changing rapidly. This research programme seeks to establish the views of practising engineers about the future demands that will be placed upon them and then examines the views of engineering educators on the approaches that can be taken to prepare engineers for these future roles. The research focused upon related developments in engineering in two countries, Malaysia and the United Kingdom (UK), and in two engineering disciplines, civil and manufacturing engineering. The methodology employed in the first phase of the research was a scenario-based approach in which engineers were asked to assess the Implications for engineers of two major change developments, triggered by information and communication technology (IT); 'processes improvement' and 'globalization'.

Abstract:
Twentieth Century Americans witnessed the construction of numerous massive dams that controlled the flow of rivers across the country. Many of these dams were built by the U.S. Army Corps of Engineers to improve navigation and to provide inexpensive electricity and flood control. This paper will seek to shed light on Georgia’s current water crisis by analyzing the initial purposes behind the building of Buford Dam in North Georgia, investigating how water supply issues were addressed in the first half of the twentieth century, and exploring how expectations of the Chattahoochee River changed over time due in part to metropolitan Atlanta’s population growth. This paper will show that Atlanta area leaders secured appropriations for Buford Dam primarily to obtain a reliable water supply and additional electricity for their burgeoning community.

Дисертація на здобуття наукового ступеня кандидата педагогічних наук за спеціальністю 13.00.07 – теорія і методика виховання. – Вінницький державний педагогічний університет імені Михайла Коцюбинського, Вінниця, 2018. У дисертації теоретично обґрунтовано, розроблено та експериментально перевірено педагогічні умови формування лідерської позиції майбутніх інженерів у закладах вищої освіти технічного профілю. В дисертації вперше визначено поняття лідерської позиції майбутнього інженера, як усвідомленої готовності до виконання ролі лідера та сукупності всіх відносин його особистості до дійсності, що склалася в певну систему групових взаємовідносин, породжених цим усвідомленням. Базовими компонентами лідерської позиції визначено: мотиваційно-ціннісний, когнітивний, діяльнісний і особистісний. Експериментально доведено, що педагогічними умовами формування лідерської позиції майбутнього інженера у закладі вищої технічної освіти є: залучення студентів у практичну самостійну діяльність, що передбачає застосування організаційних, комунікативних, когнітивних, рефлексивних умінь і зумовлює прояв їх лідерської позиції; моделювання професійно-орієнтованих завдань, що вимагають від студентів вибору оптимальних способів лідерського впливу у ситуаціях діалогічної та групової взаємодії; виховання ціннісного ставлення до лідерської позиції в позааудиторній та аудиторній роботі.
The Thesis Research for obtaining the Degree of the Candidate of Pedagogic Sciences majoring in 13.00.07 – Theory and Methods of Education.– Vinnytsia Mykhailo Kotsiubynsky State Pedagogical University, Vinnytsia, 201 8. In the dissertation, pedagogical conditions for the formation of a leading position of future engineers in higher technical educational institutions are theoretically substantiated and experimentally verified. The dissertation firstly defines the notion of leadership position of the future engineer as a conscious readiness to fulfill the role of the leader and the totality of all relations of his personality to the reality that has developed into a certain system of group relationships generated by this awareness. The basic components of a leadership position are defined: motivational-valuable, cognitive, activity and personal. It has been experimentally proved that the pedagogical conditions of forming the leadership position of a future engineer in a higher technical educational institution are: the inclusion of students in practical, independent activity, which involves the use of organizational, communicative, cognitive, reflexive skills and determines the manifestation of their leadership position; modeling of professionally-oriented tasks requiring students to choose the best ways to influence leadership in situations of group interaction; the upbringing of a value relation to a leadership position in classroom work.

Highly automated cars -- unlike robots in factories -- must operate in existing social spaces, which are complex and hard to control. Unlike household robots, these systems are also fast and dangerous. The fundamental problem of getting robots to interact in the world will be getting them to do the "right thing" -- according to developers, users, and societies. But what is "right" is a matter of perspective, and there will be many ways to achieve any particular robotic performance. Through ethnographic fieldwork at a site of robotic vehicle development, I investigate alternative strategies for robotic cars and discuss their social implications. Supported by a framework from multispecies ethnography and the practices of robot developers, I argue that robots do not see like humans or experience the world as humans do. But they must be explicitly made to think -- to represent the world and act in it --
in ways that work for people, and obey people's intersubjective assumptions about how robots will act in a given moment. Faced with this difficult set of design constraints, developers seek to humanize robots to make them socially acceptable, or robot-proof the world to make it safer for robots, through four idioms or strategies of heterogeneous engineering: mapping and annotating, perceptual omniscience, AI decision-making, and human-in-the-loop supervised operation. Social scientists involved in the design process challenge and complicate these four approaches, and introduce a fifth one: humanizing robots by allowing them to communicate via external human-machine interfaces. These idioms form a language by which to characterize approaches to socially integrated robotic systems. The debates between them show that different humanizing idioms imply different perspectives on social order, what it takes to be a competent social actor, and how humans and machines can work together.
Each idiom imagines different kinds of future worlds in which robotic technologies come to coexist with humans, with vastly different political consequences. Social scientists are vital participants in the project of exploring the contours of these futures, and I suggest new approaches and open questions for the development of social scientists' engagement in technology development.

Abstract:

The military industry has come to look at games as means for better looking and cheaper simulations. Altering games and game engines are not necessarily easy and finding a suitable engine is essential to project success. The features and design of an engine must to a large degree overlap that of the project design.

Creating ‘systems of systems’ by integrating external components/systems with games is what to a large extent differentiate military serious games from other fields. However, this is not an easy task, as games are not designed with interoperability in mind. This report explain how games and game engines can be used to create military serious games, and by that explain what need to be done to have a game interoperate with external systems, how to interact with the game engine, and give guidelines to the process of evaluating and selecting a game engine. The report also argues that game engines are not always the optimal solution.

Full text
Abstract:
Direct Injection Spark Ignition has become popular within the automotive industry due to the flexibility in injection strategies. This, along with the introduction of novel fuels such as mixtures of ethanol or butanol with gasoline, requires new understanding of the air-fuel mixture preparation and combustion as fuel properties vary greatly. The motored engine flow field of an optical research engine was characterised using Laser Doppler Velocimetry and Particle Image Velocimetry and analysed regarding turbulence properties at the world wide mapping point. The intake flow effect on the spray of a pressure swirl injector was investigated using the base fuels gasoline, isooctane, ethanol and butanol. Furthermore, low percentage splash blended mixtures of 25 % ethanol and 16 % or 25 % butanol with the reference fuels were created and geometrical spray features were obtained from high speed imaging along with the droplet sizes using Phase Doppler Anemometry. Spray investigations were also under taken in a quiescent environment with a more modern spark eroded multi hole injector and its direct replacement featuring a novel Laser drilled nozzle. The results highlight the strong effect of the fuel type, where especially pure butanol showed largest difference to the baseline fuels in terms of shape along with a significant increase of the droplet size. Ethanol also showed an increase in droplet size but only small differences to gasoline’s spray shape at 80 bar or 120 bar fuel pressure into 0.5 bar or 1 bar ambient air at 20 °C, for fuel temperatures of 20 °C or 80 °C. The ethanol mixture was typically more similar to gasoline than the butanol blends. Thermodynamic parameters were derived using incylinder pressure analysis for stoichiometric (λ=1) and lean (λ=1.2). Additionally, high speed chemiluminescence imaging was used at gasoline’s maximum break torque spark timing, calculating flame radii, radius growth, roundness and centroid development. Further analysis was using flame tomography for better insight into the early stages after ignition and the flame front characteristics for the base fuels only. Overall, the analysis showed little difference between gasoline and the blends, but showed changes for the pure alcohols with typically much faster flame progression of ethanol and issues with the combustion of butanol at low engine temperatures. The tomography analysis returned similar flame structures for the pure fuels, what is confirmed by their location in combustion diagrams.

There are over 60,000 buses in the United States and each year over 3,000 new buses of approximately 40 feet in length are purchased. The bus market has a growth rate of four to five percent per year over the last two years. The improvements in technology offered by United States companies prove unsatisfactory in terms of bus performance and the emissions of new buses. The energy crisis in the United States and concern over the health hazards of the diesel fuel exhaust gases and particulates, alternative fuel vehicles are in great demand in the transit market world wide.

Abstract:
[ES] El trabajo de investigación presentado en esta tesis es el resultado de varios años dedicados al desarrollo, la implementación y la optimización de dos tecnologías combinadas: un concepto de combustión innovador y una arquitectura de motor de nuevo diseño. Esta investigacion se ha realizado en el marco de una colaboración con Renault SA, como continuación de las actividades realizadas en el proyecto europeo POWERFUL (POWERtrain for FUture Light-duty vehicles) por un lado,y en el marco del proyecto europeo REWARD (Real World Advanced technologies foR Diesel engines), devenido como continuación del proyecto POWERFUL en el marco del programa de investigación Horizonte 2020, por otro lado. Los principales objetivos de estos estudios eran evaluar el potencial del concepto de combustión parcialmente premezclada (PPC) operando con gasolina como combustible en un innovador motor de 2 tiempos de válvulas en culata, y luego diseñar una nueva geometría de motor de 2 tiempos utilizando la arquitectura Uniflujo para superar los principales problemas y limitaciones observados durante la primera etapa, que se pueden resumir principalmente en el rendimiento de barrido (especialmente trabajando en cargas elevadas). La metodología diseñada para este trabajo de investigación sigue un enfoque teórico-experimental. La evaluación del concepto de combustión PPC operando con gasolina se llevó a cabo principalmente con un enfoque experimental con el apoyo del análisis en línea directamente en el banco de ensayo, seguido de un exhaustivo tratamiento posterior de los datos y de un análisis detallado del proceso de combustión utilizando herramientas de diagnóstico. Por el contrario, el desarrollo del nuevo motor Uniflujo de 2 tiempos consistió principalmente en iteraciones sobre modelado 3D-CFD, si bien las actividades experimentales fueron fundamentales para validar las diferentes soluciones propuestas y evaluar su sensibilidad ante diferentes parámetros de interés utilizando una metodología de Diseño de Experimentos (DoE). La primera parte del trabajo se ha dedicado a la comprensión de los procesos termodinámicos involucrados en la combustión operando con el concepto PPC en un motor de 2 tiempos de válvulas en culata utilizando gasolina como combustible, y a evaluar su potencial en términos de emisiones contaminantes, consumo de combustible y ruido. Por último, se ha realizado un trabajo de exploración para ampliar en la medida de lo posible el rango de funcionamiento de este concepto de combustión en esta configuración específica del motor, investigando especialmente el rendimiento en cargas bajas en todo el rango de regímenes de giro del motor, y estableciendo también las principales limitaciones para la operación en cargas altas. La segunda parte de la tesis se ha centrado en el desarrollo y optimización teórica de un motor Uniflujo de 2 tiempos de nuevo diseño, incluyendo su fabricación y validación experimental. El objetivo principal era optimizar, utilizando principalmente simulaciones 3D-CFD, el rendimiento de barrido de esta arquitectura de 2 tiempos mediante el diseño de nuevas geometrías de puertos de admisión, permitiendo un gran control sobre el flujo de aire hacia y a través del cilindro para barrer al máximo los gases quemados y minimizar el cortocircuito de aire fresco hacia el escape. Las soluciones óptimas se evaluaron experimentalmente siguiendo la metodología DoE, antes de comparar finalmente los resultados de rendimiento de barrido con la anterior arquitectura de motor de 2 tiempos con válvulas en culata.
[CA] El treball de recerca presentat en aquesta tesi és el resultat de diversos anys dedicats al desenvolupament, la implementació i l'optimització de dues tecnologies combinades: un concepte de combustió innovador i una arquitectura de motor de nou disseny. Aquesta recerca s'ha realitzat en el marc d'una col·laboració amb Renault SA, com a continuació de les activitats del projecte europeu *POWERFUL (*POWERtrain *for *FUture Light-*duty *vehicles) d'una banda, i en el marc del projecte europeu *REWARD (Real *World *Advanced *technologies *foR Dièsel *engines), es devingut com a continuació del projecte *POWERFUL en el marc del programa d'investigació Horitzó 2020, d'altra banda. Els principals objectius d'aquests estudis eren avaluar el potencial del concepte de combustió parcialment premesclada (PPC) operant amb gasolina com a combustible en un innovador motor de 2 temps de vàlvules en culata, i després dissenyar una nova geometria de motor de 2 temps utilitzant l'arquitectura Uniflux per a superar els principals problemes i limitacions observats durant la primera etapa, que es poden resumir principalment en el rendiment d'escombratge (especialment treballant en càrregues elevades). La metodologia dissenyada per a realitzar aquests treballs de recerca segueix un enfocament tant experimental com teòric. L'avaluació del concepte de combustió PPC operant amb gasolina es va dur a terme principalment amb un enfocament experimental, però sempre amb el suport de l'anàlisi en línia directament en el banc d'assaig, seguit d'un exhaustiu tractament posterior de les dades combinat amb una anàlisi detallada del procés de combustió utilitzant eines de diagnòstic. Per contra, el desenvolupament i el disseny del nou motor Uniflux de 2 temps va consistir principalment en iteracions sobre modelatge 3D-CFD, si bé les activitats experimentals van ser fonamentals per a validar les diferents solucions proposades i avaluar la seua sensibilitat davant una sèrie de paràmetres d'interés utilitzant una metodologia de Disseny d'Experiments (DoE). La primera part del treball s'ha dedicat a la comprensió dels processos termodinàmics involucrats en la combustió operant amb el concepte de combustió PPC en un motor de 2 temps de vàlvules en culata utilitzant gasolina com a combustible, i a avaluar el seu potencial en termes d'emissions contaminants, consum de combustible i també de soroll. Finalment, s'ha fet un treball d'exploració per a ampliar en la mesura que siga possible el rang de funcionament d'aquest concepte de combustió utilitzant eixa configuració específica del motor, investigant especialment el rendiment en càrregues baixes en tot el rang de règims de gir del motor, i establint també les principals limitacions per a l'operació en càrregues altes. La segona part de la tesi s'ha centrat en el desenvolupament i optimització teòrica d'un motor Uniflux de 2 temps de nou disseny, incloent la seua fabricació i validació experimental. L'objectiu principal era optimitzar, utilitzant principalment simulacions 3D-CFD, el rendiment d'escombratge d'aquesta arquitectura de 2 temps mitjançant el disseny de noves geometries de ports d'admissió, permetent un gran control sobre el flux d'aire cap a i a través del cilindre per a escombrar al màxim els gasos cremats i minimitzar el curtcircuit d'aire fresc cap a l'escapament. Les solucions òptimes es van fabricar i van avaluar experimentalment seguint la metodologia DoE, abans de comparar finalment els resultats de rendiment d'escombratge amb l'anterior arquitectura de motor de 2 temps amb vàlvules en culata.
[EN] The research work presented in this thesis is the result of several years dedicated to the development, implementation and optimization of two combined technologies: an innovative combustion concept and a newly designed engine architecture. These investigations have been performed in the framework of a research collaboration with Renault SA following up the activities performed along the European POWERFUL project (POWERtrain for FUture Light-duty vehicles) on the one hand, and in the framework of the European REWARD project (REal World Advanced technologies foR Diesel engines), brought as a continuation of the POWERFUL project in the frame of the Horizon 2020 research program, on the other hand. The main objectives of these studies were to evaluate the potential of the Partially Premixed Combustion (PPC) concept operating with gasoline fuel in an innovative 2-Stroke poppet-valve engine, and then to design a new 2-Stroke engine geometry using the Uniflow architecture to overcome the main problems and limitations observed during the first stage, which can be mainly summarized to the scavenging performance (especially at high loads). The methodology designed for performing these investigation is based on both experimental and theoretical approaches. The evaluation of the gasoline PPC concept was carried out mainly experimentally, but always supported by online analysis directly on the test-bench and followed by a thorough post-processing of the data combined with a detailed analysis of the combustion using combustion diagnostic tools. On the contrary, the development and design of the new 2-Stroke Uniflow engine consisted mainly of 3D-CFD iterations, but experimental testing was crucial to validate the different solutions proposed and evaluate their sensitivity to a set of parameters of interest using a Design of Experiments (DoE) methodology. The first part of the work has been dedicated to the understanding of the thermodynamical processes involved in the combustion in a poppet-valve 2-Stroke engine operating with the gasoline PPC concept, and to evaluate its potential in terms of pollutant emissions, fuel consumption and also noise. Finally, a wide exploration has been performed to extend as much as possible the operating range of this combustion concept using that specific engine configuration, especially investigating the low loads performance throughout the full range of engine speeds, and also laying out the main limitations for high-to-full load operations. The second part of the thesis has been focused on the development and theoretical optimization of a newly designed 2-Stroke Uniflow engine, leading to manufacture and experimental validation. The main objective was to optimize, using mainly 3D-CFD modeling simulations, the scavenging performance of this 2-Stroke architecture by designing new intake ports geometries and to enable a great control over the air flow into and through the cylinder in order to scavenge the burnt gases as much as possible while minimizing the fresh air short-circuit to the exhaust. The optimum solutions were then manufactured and experimentally tested following a DoE methodology, before finally comparing the results of the scavenging performance to the previous 2-Stroke poppet-valve engine architecture.

The software industry needs professionals who, in addition to technical knowledge, possess certain skills that positively affect the development process software. In this dissertation initially held up a mapping systematic about which skills are reported in the literature as being more important for the software engineer. This mapping served to limit the scope of this work to the skills of communication and collaboration. The development of communication skills and collaboration, according to several authors, occurs from practical activities. Therefore, try to enable the best students, with regard to communication and collaboration, would integrate them into projects with industry. However, it is not always possible to establish partnerships with industry software. An alternative is to simulate the industrial scenario in the academic environment. A practice that has grown in the industry is the geographical distribution of staff development, known as Distributed Software Development (DSD). Then, simulate a scenario DDS is a possible way to bring students from reality of the software industry. This is the approach proposed in this dissertation. Two experimental studies were conducted to obtain evidence about the effectiveness the proposed pedagogical approach. Every experiment we sought to improve way of collecting and analyzing data, and performed the triangulation of these data aimed obtaining the most reliable conclusions. It was observed that the use DDS is quite motivating for students, but there are other factors that This affect motivation, such as the affinity between team members co-allocated. Properly manage these factors in order to maintain participants motivated, can be the difference between success and failure of the activity of teaching, one Since skill development is influenced by motivation.
A indústria de software precisa de profissionais que, além do conhecimento técnico, possuam determinadas habilidades que afetam positivamente o processo de desenvolvimento de software. Nesta dissertação de mestrado realizou-se inicialmente um mapeamento sistemático sobre quais habilidades são reportadas pela literatura como sendo mais importantes para o engenheiro de software. Este mapeamento serviu para limitar o escopo deste trabalho às habilidades de comunicação e colaboração. O desenvolvimento de habilidades de comunicação e colaboração, segundo diversos autores, ocorre a partir de atividades práticas. Portanto, tentar capacitar melhor os alunos, no que diz respeito à comunicação e colaboração, seria integrá-los em projetos com a indústria. Todavia, nem sempre é possível estabelecer parcerias com a indústria de software. Uma alternativa é simular o cenário industrial em ambiente acadêmico. Uma prática que tem crescido na indústria é a distribuição geográfica da equipe de desenvolvimento, conhecida como Desenvolvimento Distribuído de Software (DDS). Então, simular um cenário DDS é uma possível forma de aproximar os alunos da realidade da indústria de software. Esta é a abordagem proposta nesta dissertação. Foram realizados dois estudos experimentais visando obter indícios sobre a eficiência da abordagem pedagógica proposta. A cada experimento buscou-se aprimorar a forma de coleta e análise dos dados, e efetuou-se a triangulação destes dados visando a obtenção de maior confiabilidade para as conclusões. Observou-se que a utilização de DDS é bastante motivadora para os alunos, todavia existem outros fatores que afetam esta motivação, como por exemplo a afinidade entre os membros das equipes co-alocadas. Gerenciar adequadamente tais fatores, visando manter os participantes motivados, pode ser o diferencial entre sucesso e fracasso da atividade de ensino, uma vez que o desenvolvimento de habilidades é influenciado pela motivação.
