Abstract:

Esse trabalho descreve uma investigação prática e teórica de características aerodinâmicas de um modelo referente a um avião bimotor leve \"Piper PA-34 SENECA III\" construído em escala 1:6,5. Basicamente, duas configurações fazem parte da avaliação: \"asa limpa\" e Nacele \"Pusher\". O principal objetivo é o de avaliar o comportamento aerodinâmico da configuração \"Pusher\" em três diferentes posições através da obtenção de dados práticos e teóricos de distribuição de pressão estática no aerofólio e no próprio nacele na condição não motorizada. A metodologia emprega testes em túnel de vento de baixa velocidade para a aquisição dos dados experimentais através da variação do ângulo de ataque para as configurações citadas. A obtenção dos dados numéricos, como comparativos aos experimentais, é através da utilização do método dos painéis aplicado à aerodinâmica. Os resultados experimentais e teóricos mostram que a presença do nacele nas posições \"Pusher\" avaliadas gera interferência diminuindo à sustentação do aerofólio.
This work describes a practical and theoretical investigation of aerodynamic characteristics of a 1:6,5 scale model of a light twin-engined Piper Seneca III aircraft. Basically, two configurations are considered in this evaluation: clean wing and pusher nacelle. The principal objective is to evaluate the aerodynamic characteristics of the pusher configuration in three different positions, in order to obtain practical and theoretical data with reference to static pressure distribution on the surface of the aerofoil and of the nacelle in a power-off condition. The methodology employed used low speed wind tunnel test for the acquisition of experimental data for a selection of angles of attach, as cited. The generation of numerical data, to be compared the experimental equivalent, is though the use of a low order panel method. The experimental and theoretical results show that the presence of pusher nacelle in the positions mentioned generated interference, reducing the local lift of the aerofoil.

Abstract:

My name is Greg Delany Walker. I’m an MFA candidate in Theatre Arts with a specialization in Acting at the University of Iowa. The following is my thesis that addresses my artistic process as an actor. My main focus in this thesis is to unpack my beliefs about what makes good acting and how I personally achieve that. I detail many schools of thought that pair well together to seek out vulnerability in actors. Vulnerability is my chief struggle as an actor given that I have a tendency to overthink things and rely more on intellect than on passionate expression in my daily life and in my work. That tendency leads me to be polite as an actor, which has gotten in the way of my being able to reach my full potential. I discovered time and time again how important it is to understand and embody acting techniques so deeply that I can let them go. All the different techniques of analysis, physical and voice work are essential, but they need to transition to being second nature. The techniques outlined in this thesis, learned in my life and through the program at the University of Iowa, have to be so ingrained that I don’t need to think of them in the moment on stage. The key to being present on stage seems so simple in a way, but it has been a great challenge for me to fully let go of control to allow for my potential public failure and humiliation. The times that I’ve embraced failure have been the strongest moments for me as an actor because of the power of risk. My hope is that by detailing my own process and experiences, with that idea of building technique and releasing into the present moment, that others could be further empowered to do the same in acting or in life.

Abstract:

Newspapers are often bundled and packet on pallets to secure transport. Packing thebundles on pallets are often done with an automatic palletizer. For reliable operation,the bundle needed to have a correct position and orientation on the infeed conveyor.Wrong orientation can happen when the bundle is pushed from conveyor to thepalletisers conveyor. The main to reasons is wrong timing that leads to rotation of thebundle and to high pushing force that leads to tumbled bundles. The goal of thisproject is to make a prototype of a system that automatically adapts the pressure andsignal when to push using two laser sensors. One sensor sends a digital signal if laserbreaks, the other measure distance, e.g. bundle hight. The software was developed onan Arduino Uno board, and two interface board was made for voltage levelconversions. The prototype system managed to change pressure for different bundlesizes and timed the pushing signal correctly.

Full text

Abstract:

Abstract The main task for most development-intensive organisations is to create, develop and commercialise new products and services. The technology push (TP) concept is considered an important competitive advantage for companies trying to create breakthrough products. Because development processes are risky and failure rates are high, especially in the case of technology pushed projects, defined success factors are valuable knowledge for the management of development-intensive firms. The prime objective of this study is to present a compact set of TP project success factors in an information and communication technology (ICT) context. Because the literature on new product development and innovation has presented many success factors for developed products, but has done so in a way that presents the factors as having a nebulous nature, the specification of TP success factors is also presented. The success factors are also empirically validated. The goal of the validation was to determine the relevance of the success factors introduced, and potentially define new ones. The validation was performed through an empirical study with semi-structured company interviews. As a result of this study we concluded that one success factor defined through the literature review should be removed due to a lack of relevance, that the other twelve success factors were validated, and three new success factors were identified during the empirical study. Eventually fifteen TP success factors are defined and presented. The practical relevance of this study is to help firm management to recognise the real actions needed to reduce product development risks. The theoretical relevance is in helping scholars to focus on key issues when studying the key factors of breakthrough development cases
Tiivistelmä Tuotekehitystä harjoittavien yritysten päätehtävänä on luoda, kehittää ja kaupallistaa uusia tuotteita ja palveluita. Yritysten pyrkiessä luomaan läpimurtotuotteita, ”Technology push” -konseptia pidetään niille tärkeänä kilpailuetuna. Koska tuotekehitysprosessit ovat riskialttiita ja epäonnistumisen mahdollisuudet suuret erityisesti teknologiatyöntöisillä projekteilla, tarkasti määritellyt menestystekijät ovat arvokasta tietoa yritysten johdolle. Tämän työn päätarkoituksena on esitellä yhtenäinen ja tiivis joukko teknologiatyöntöisten projektien menestystekijöitä ICT toimialalla. Uusien tuotteiden kehittämistä ja innovaatioita käsittelevä lähdekirjallisuus esittelee lukuisia menestystekijöitä. Ne on kuitenkin esitelty vaikeasti selitettävällä tai monimerkityksellisellä tavalla, joten olemme esittäneet myös niiden tarkat määrittelyt. Menestystekijät ovat validoitu myös empiirisesti. Validoinnin tarkoituksena oli löytää esiteltyjen menestystekijöiden relevanssi ja löytää mahdollisesti uusia menestystekijöitä. Validointi toteutettiin puolistrukturoiduilla yrityshaastatteluilla. Työn tuloksena esitetään kirjallisuuskatsauksen ja empiirisen validoinnin avulla määritellyt 15 teknologiatyöntöisten projektien menestystekijää. Tutkimuksen käytännöllinen merkitys on auttaa yritysjohtoa tunnistamaan tärkeät toiminnot tuotekehitysriskien madaltamiseksi. Tutkimuksen teoreettinen merkitys on auttaa tutkijoita keskittymään avainasioihin ja tunnistamaan menestystekijät läpimurtotuotetutkimuksessa

Salas, Susan. "Pipeline dreams| Latina/o community college students pushed out of the transfer path." Thesis, California State University, Long Beach, 2015. http://pqdtopen.proquest.com/#viewpdf?dispub=3708287.

Full text

Abstract:

Latinas/os represent the largest ethnic group in California and are under-represented in higher education. Latina/o student college completion rates are the lowest of any racial or ethnic group, including Whites. This study used a critical race theoretical lens to explore the experiences of 14 Latina/o community college students who were pushed out of the transfer path. Storytelling served as the foundation of this study to understand and give voice to Latina/o students' transfer path experiences. Interview data from all participants were analyzed to extract codes and develop themes within the stories. Demographic surveys were evaluated to identify student characteristics.

Findings revealed that Latina/o students were pushed out of the transfer path at four critical points: Students were pushed out as they found themselves on academic or progress probation, resulting in conditional financial aid suspensions. Some students became discouraged as they figured out the amount of courses necessary to become transfer ready. Other students attempted to transition to transferable coursework, but they were unable to pass developmental math courses. Students also reported being pushed out as they learned about the immense amount of transfer requirements, program options, and costs, which created transfer information paralysis.

Latina/o students reported feeling emotional relief after being pushed out of the transfer pathway. Earning an associate's degree or certificate was an achievable goal and students felt a sense of academic accomplishment. Students also believed that an associate's degree was a "stepping stone" on their journey through the educational pipeline.

Students noted race, class, and gender stereotyped experiences that adversely affected their transfer path experiences. Negative perceptions about their race impacted their academic performance. Erratic and limited resources-including suspension from financial aid-proved harmful to their ability to remain on the transfer path. Gender role expectations obstructed Latina women and propelled Latino men on the transfer pathway.

The findings suggest that Latina/o students were disadvantaged by community college policies and procedures. Yet, they remained committed to their educational goals. Further investigation of Latina/o student community college experiences is necessary to develop policies, procedures, and practices that will serve to strengthen their educational pathways.

Henneman, Tasha K. "Preschool expulsions| Parental experiences of Black boys who were pushed out or left behind." Thesis, Mills College, 2015. http://pqdtopen.proquest.com/#viewpdf?dispub=3683724.

Full text

Abstract:

Preschool expulsions have gained new attention in the early child care field. The disproportionate rate of Blacks boys that are expelled or "pushed out" from their child care settings suggests particular concern for exploration. Behavioral problems in early childhood have negative outcomes later in life (Keane & Calkins, 2004); therefore, it is imperative that educational systems create equitable, non-disciplinary practices, which do not marginalize or shame Black boys. This study captured the experiences of five parents of Black boys that were expelled or pushed out of multiple child care settings, as well as the temporary and lasting effects of the expulsions or "push-outs" on the entire family. One center director of a state-funded preschool and one head teacher of a private center also participated. Data were collected through face-to-face interviews, focus groups, and on-line temperament profiles. Grounded theory was used to code the data in terms of the study's conceptual framework, including relationships between parent, child and teacher/provider, Critical Race Theory (CRT), neurobiological considerations, gaps in teacher/provider preparation, and the high-stakes accountability movement. The social construction of Black boys and learning in early child care settings was also explored. Expulsions or push-outs had several negative impacts for parents, the boys of this study and their families. However, through these hardships, parents learned strong advocacy skills and showed resiliency. Implications for providers and policy are discussed.

Bellocq, Pablo. "Multi-disciplinary preliminary design assessments of pusher counter-rotating open rotors for civil aviation." Thesis, Cranfield University, 2012. http://dspace.lib.cranfield.ac.uk/handle/1826/10280.

Full text

Abstract:

As a consequence of fuel cost escalation and increased stringent engine emission regulations, interest in counter-rotating open rotor engines (CRORs) has been renewed. R&D efforts are currently ongoing to develop the technologies required to ensure the appropriate levels of structural integrity, noise, vibrations and reliability. The assessment of the impact of the main low pressure preliminary design and control parameters of CRORs on mission fuel burn, certification noise and emissions is necessary to identify optimum design regions. These assessments aid the development process when compromises need to be performed as a consequence of design, operational or regulatory constraints. These assessments are not possible with the state-of-the-art aero-engine preliminary design simulation tools. Novel 0-D performance models for counter-rotating propellers (CRPs) and differential planetary gearboxes, as well as 1-D and 0-D performance models for counter-rotating turbines (CRTs) were developed and verified using available data. These models were used to create 0-D pusher geared (GOR) and direct drive (DDOR) open rotor engine performance simulation modules allowing the independent definition of the design and operation of each of the two counter-rotating parts of the CRP and CRT. A multi-disciplinary preliminary design simulation framework was built using the novel engine performance modules together with dedicated CROR aircraft performance, engine geometry and weight, gaseous emissions and certification noise simulation modules. Design space exploration and trade-off studies were performed and minimum fuel burn design regions were identified for both the pusher GOR and DDOR. A 160 PAX aircraft flying a business mission of 500 NM was chosen for these studies. Based on the assumptions made, the main conclusions of these studies are as follows. · Fuel burn reductions of ~1-2% are possible through optimised propeller control · The propeller diameter for minimum mission fuel burn lies between 4.26 and 4.7 m · The design nozzle pressure ratio for minimum mission fuel burn lies between 1.55 and 1.6 · CRPs with 13 or 14 blades per propeller provide minimum mission fuel burn · Increasing spacing between the propellers reduces noise significantly (~6 EPNdB for each certification point) with a relatively small fuel burn penalty (~0.3-0.5%) · Relative to unclipped designs, 20% clipped CRPs reduce flyover noise by at least 2.5 EPNdB and approach noise by at least 4.5 EPNdB. The corresponding fuel burn penalty is ~2 % for a GOR and ~3.5% for a DDOR. · Sideline and flyover noise can be reduced by increasing the diameter of the CRP and appropriately controlling CRP rotational speeds. Approach noise can be reduced by either reducing the diameters or the rotational speeds of the propellers. · The rotational speed of the forward propeller for minimum noise is higher than that for minimum mission fuel burn for all the studied CROR designs. · Regardless of clipping, reducing the rotational speed of the rear propeller relative to the forward propeller reduces noise and, to a certain limit, also mission fuel burn. (further reductions in rotational speed would have an adverse effect on fuel burn) · An increase in the number of blades results in an increase in certification noise. The main recommendations for further work are as follows. · Integrating the 1-D CRT model with the 0-D DDOR performance model in order to assess the impact of different CRT design criteria at engine and mission levels · Developing preliminary design methods to account for changes in aircraft weight and aerodynamics due to changes in engine design and required cabin noise treatment.

Abstract:

This dissertation investigates the latent potential of the mining belt in Johannesburg through a regenerative theory, by placing a catalytic intervention which respects the heritage of the mining belt, with a focus on the ecology and the socio-economic value of the land has, thereby turning a liability into an asset. This intervention is seen as the first point of acupuncture in a long rehabilitation process and focuses on using this space to deal with context specific issues. The proposed intervention will investigate the potential of architecture to activate a harmed dormant space in the realm of a decentralized city node. It recognizes the potential of the currently fragmented mining belt to become a gateway to the South of Johannesburg, and embraces an opportunity to restitch the urban fabric.

Full text

Abstract:

Young, poor, and undereducated women of color make up the majority of women who are incarcerated in the U.S. correctional system (Covington & Bloom, 2003). Black girls, in particular, are at risk of incarceration when schools leverage policies and practices (e.g. exclusionary discipline) that focus on discipline and control rather than providing a high quality education and support services for Black girls’ development. The restorative leadership program model employs unique methods to engage students and elevate their unique talents and perspectives in a school system that does not “effectively adjust and reform to fit the needs of its entire population” (Dr. Dorian Burton, personal communication, March 26, 2016). The program prioritizes educational attainment for Black girls through physical sports and field trips, critical conversations about what it means to grow up as a Black girl, events to collaborate and build relationships with peer and adult mentors, and workshops to learn personalized goal setting and reflection techniques. A restorative leadership program is an effective tool public middle schools can use to (1) increase the social emotional support provided to Black girls in order to reduce delinquent behavior and (2) reduce the number of Black girls who are pushed out of schools into the juvenile justice system.

Abstract:

In the United States, a staggering four thousand students drop out every school day. Moreover, in 2016, the graduation rate in Oregon was only 74.8%, one of the lowest in the nation. Research shows that a disproportionate number of youth leaving school are from historically marginalized communities. Many of these youth resiliently return to education at alternative schools. This research sought to explore the educational experiences of youth in alternative schools in their own voices and perspectives. From a theoretical framework based in sociocultural theory, cultural capital, and critical theory, this study underscored the importance of youth voice in changing the education system by incorporating qualitative methods and YPAR (Youth Participatory Action Research). Working alongside seven youth co-researchers who attended an alternative school in Oregon, we interviewed eight other students at the same school about their educational experiences and perceptions of the education system. The youth co-researchers and I co-constructed four themes collectively: “I felt invisible to the teachers”; “Teaching is a sacred act”; “Regular high school is like drowning, it’s cruel”; and “Dropping out was [actually] a success.” We also compiled counternarratives in the words of the eight student participants, which highlighted how the school system pushed them out despite their desire to learn. Finally, we spoke truth to power, in solidarity with the youth in this study, by presenting our recommendations for educational change to teachers, including how they can co-create spaces with students that foster care and empathy, value youth voice, and are culturally sustaining and identity affirming.

BACKGROUND: The prevalence of the pusher syndrome can affect patients' motor recovery after stroke (CVA). OBJECTIVES: To establish the prevalence of pusher syndrome in patients after stroke from clinical criteria contained in Contraversive Pushing Scale (evaluation of the symptom of pushing), and correlate them with neurological abnormalities, severity of stroke and functionality. METHODS: a cross-sectional study with convenience sample of patients of both sexes with a diagnosis of acute stroke. We included patients with clinically stable and able to assess the severity of the event from the range of NIHSS, Barthel (evaluation of the symptom of pushing). To diagnose the pusher syndrome used two scoring criteria with different cutoff points, pushing the Contraversive scale: result greater than or equal to 1 (criterion I) or greater than zero (criterion II).RESULTS: 86 patients were evaluated. Of these 30 met the inclusion criteria. 17 were men with mean age of 52. 3 years. 26 patients had ischemic stroke and hemorrhagic stroke four. 14 had hemiplegia on the left and 16 right. Mean NIHSS and Barthel index were 8. 5 and 48. 8 points respectively. Using the criteria I and II prevalence rates were 3. 3% and 26. 6% respectively. The presence of pusher syndrome was significantly associated with lower values when the Barthel scale, we used the criterion II (22. 5 ± 8. 5 versus 58. 4 ± 27. 3, P <0. 001). CONCLUSIONS: The prevalence of pusher syndrome in patients after acute stroke is significant and can vary according to the criteria used. Its presence is associated with clinical severity and functional dependence, higher incidence in ischemic stroke event, parietal lobe and middle cerebral artery, respectively.
BASE TEÓRICA: A identificação da síndrome de pusher pode influir na recuperação motora dos pacientes após acidente vascular encefálico (AVC). OBJETIVOS: estabelecer a prevalência da síndrome de pusher em pacientes após AVC a partir de critérios clínicos contidos na contraversive pushing scale (avaliação do sintoma de empurrar) e correlacioná-la com anormalidades do exame neurológico, gravidade do AVC e funcionalidade. MÉTODOS: realizou-se estudo transversal com amostra de conveniência de pacientes de ambos os sexos, com diagnóstico de AVC agudo. Foram incluídos pacientes clinicamente estáveis e com possibilidade de avaliação da severidade do evento a partir da escala de NIHSS, Barthel e (avaliação do sintoma de empurrar). Para o diagnóstico da síndrome de pusher utilizaram-se dois critérios de pontuação, com diferentes pontos de corte, na contraversive pushing scale: resultado maior ou igual a 1 (critério I) ou maior que zero (critério II).RESULTADOS: foram avaliados 86 pacientes. Destes 30 preencheram os critérios de inclusão. 17 eram homens com idade média de 52,3 anos. 26 pacientes tiveram AVC isquêmico e quatro AVC hemorrágico. 14 apresentaram hemiplegia à esquerda e 16 à direita. As médias do NIHSS e do índice de Barthel foram de 8. 5 e 48. 8 pontos, respectivamente. Utilizando-se os critérios I e II as prevalências foram de 3. 3% e 26. 6%, respectivamente. A presença de síndrome de pusher associou-se significativamente a valores mais baixos na escala de Barthel quando se utilizou o critério II (22,5±8,5 versus 58,4±27,3; P< 0, 001). CONCLUSÕES: a prevalência da síndrome de pusher em paciente pós - AVC agudo é significativa e pode variar de acordo com critérios utilizados. Sua presença associa-se a parâmetros clínicos de maior gravidade e dependência funcional, maior incidência do evento em AVC isquêmico, lobo parietal e artéria cerebral média, respectivamente.

Abstract:

Detta är ett examensarbete på 15 högskolepoäng inom Teknisk design vid Luleå Tekniska Universitet. Arbetet har genomförts på uppdrag av Nevo Maskin AB som är en företag som utför reparationer och service av entreprenadmaskiner. Detta produktutvecklingsprojekt har genomförts i samarbete med Sigma Industry East North. Syftet med detta projekt är att förbättra och förenkla arbetet med en Trackpress. Arbetet ska göras säkrare, mobilt och mer ergonomiskt för användaren. En Trackpress används för att demontera och byta masterpinne i länken på larvkedjan på en grävmaskin. Detta arbete behandlar mellansegmentet (12-45 ton) av grävmaskiner. Verktyget som används på Nevo Maskin består av tre huvudsakliga delar: en bygel som läggs ovanpå bandet, en cylinder som expanderar med hjälp av tryckluft och en kompressor som styr tryckluften. Kompletterande delar måste användas mellan länken och cylindern för att den ska nå att pressa ut masterpinnen på länken. Verktyget väger 86 kg och kan inte hanteras av en person, utan ett lyfthjälpmedel måste användas. Ibland lyfts verktyget av två personer, men detta är ytterst oergonomiskt och medför stora risker för arbetsskador. För att förbättra detta verktyg har vi arbetat efter en designprocess där faser med förstudie, litteraturstudie, idéarbete och detaljutveckling genomförts för att utveckla ett koncept. I designprocessen som används i det här projektet är en av faserna idéarbete, där vi använt oss av workshops där medlemmarna skissar, diskuterar och skriver ned idéer som kommer fram. Genom att använda oss av olika metoder och olika grupper av människor i våra workshops kunde vi få flera infallsvinklar på problemet. Vidare har vi inom de olika faserna genomfört studiebesök, användarstudier, intervjuer, marknadsundersökning och kreativa metoder för att arbeta fram ett koncept som ritades upp i NX och Inventor. Resultatet är ett utvecklat verktyg kallat Masterpusher som består av tre delar. En ram uppbyggd av två parallella plåtar, med en platta baktill där cylindern placeras mellan de två sidoplåtarna, en domkraft för positionering av hydraulcylindern i höjdled och en insats för centrering av verktyget. I botten på ramen finns två skenor för att cylindern och domkraften inte inte ska falla ned. Ett kompletterande koncept för förflyttning och transport har rekommenderats för vidareutveckling. Konceptet medger säkrare hantering och mer ergonomiskt arbetssätt. Vikten har reducerats och materialåtgången minskats. Förbättringen innebär även en minskad produktionskostnad vilket bidrar till en konkurrensfördel jämfört med de konkurrenter som finns idag. Nyckelord: Industridesign, Teknisk design, Konstruktion, Master pin pusher, Produktutveckling, Ergonomi, Nevo Maskin AB
This is a bachelor degree project in Industrial design engineering at Luleå University of Technology. It has been carried out at the request of Nevo Maskin AB, a company that performs service and repairs on heavy construction equipment. The project has been executed in collaboration with Sigma Industry East North in Luleå. The purpose of this project is to improve and simplify the work with a Trackpress. The work process must be made safe, mobile and ergonomic for the user. The Trackpress is a tool that is used for dismantling and replacing the master pin in the link of the caterpillar chain on excavators. The project covers the middle segment of excavators which means excavators between 12 to 45 tons and this is the most common segment of excavators repaired by Nevo Maskin AB. The Trackpress tool used by Nevo Maskin AB consists of three parts: a frame that is placed over the caterpillar chain, a hydraulic cylinder that expands by compressed air and a compressor that controls the compressed air. Supplementary parts are needed between the link and cylinder in order for it to reach the master pin, here they use whatever they have in reach. The exciting Trackpress weighs 86 kgs and cannot be lifted by one sole person, a lifting device must be used. Sometimes two people lifts it but this is not to recommend because of the great risk of injuries. To improve the Trackpress the project has been carried out through a design process with five phases of planning, feasibility study, literature study, ideation and detail development to develop a concept. in one of the phases, Ideation, we have worked with workshops where the members draw, discuss, and write down all the ideas generated. By using different methods and groups of people in the workshops we got different angles and points of view on the problem. Furthermore we have done field trips, user studies, interviews market research and creative methods to develop a concept that was drawn in NX and Inventor. The final concept consists of three parts, a frame constructed by two parallel steel plates with another plate in the rear, a jack for positioning the cylinder, which is placed on top of the jack and between the parallel plates and a additional part for centering the tool over the chain. In the bottom there are two rails that keep the jack in place. A concept for transporting the tool has been left for future development. The concept idea gives the user safer handling of the tool and a more ergonomic way of working with it. The weight and the material consumtion has been reduced. This improvement also reduces de production cost whitch gives the company an advantage against other competitors in the same segment.

Abstract:

Programas sofrem diversas modificações ao longo das etapas de desenvolvimento, implantação e manutenção. A evolução de um software pode ter várias causas: correção de erros, inclusão de novas funcionalidades ou até mesmo, como é o caso de programas orientados a aspecto, transformações estruturais podem fazer parte da semântica do sistema. Apesar de modificações serem comuns, não é tarefa trivial prever como estas afetam o comportamento dos programas, já que os componentes de software normalmente interagem de forma complexa, o que faz com que mesmo pequenas alterações possam introduzir comportamentos indesejados. Transformação de grafos, também conhecida como reescrita de grafos, é um importante paradigma para modelagem e análise de sistemas. Modelos baseados em transformação de grafos, como gramáticas de grafos, permitem uma modelagem ao mesmo tempo intuitiva e com semântica precisa, permitindo a aplicação de técnicas de análise como verificação de modelos e análise de par crítico no estudo do comportamento de sistemas. A teoria por trás de transformação de grafos vem sendo desenvolvida a várias décadas, e atualmente está descrita de uma forma bastante abstrata. Contudo, ainda não possui uma definição natural de reescritas de alta ordem, que facilitaria a definição de evolução de especificações compostas por regras de reescrita de grafo, tais como gramáticas de grafos. Nesta tese são abordadas a modelagem e a análise de sistemas sob modificações programadas no contexto de gramáticas de grafos. A generalização da abordagem de pushout duplo para reescrita de grafos é utilizada como o princípio geral para descrever, simultaneamente, a semântica do sistema e modificações estruturais. Para tal, introduzimos uma noção de reescrita de segunda ordem para modificar a estrutura de regras de transformação de grafos, e usando isso, definimos modelos equipados simultaneamente de regras de primeira e segunda ordem, chamados gramáticas de grafos de segunda ordem. Através destes modelos podemos representar simultaneamente transformações estruturais e execução do sistema, e relacionar formalmente ambos tipos de reescrita. Também propomos novas técnicas para investigar o efeito da modificação de regras sobre a aplicação destas. Finalmente, como um exemplo de aplicação da teoria, caracterizamos construções de sistemas orientados a aspectos através de gramáticas de grafos de segunda ordem, e discutimos como utilizar as novas técnicas para estudar o efeito da combinação aspectual sobre o sistema inicial.
Software systems are not static entities: they usually undergo several changes along their development and maintenance cycles. Software evolution may be required for several reasons, such as the inclusion of new functionalities, the correction of errors or even as part of the system semantics, as it is the case of aspect-oriented systems. However, it is usually not trivial to foresee how structural changes can affect the system behaviour, since system components often interact in very complex ways, and even trivial modifications may introduce new problems. Graph transformation, also known as graph rewriting, has been used throughout the years as an important paradigm for system modelling and analysis. Models based on graph transformation, such as graph grammars, allow an intuitive but formal representation of the system behaviour, allowing the usage of analysis techniques such as model checking and static analysis of rule interaction. The theory behind graph transformation is quite general, and has been studied since the 1970s. However, it still lacks a general notion of higher-order rewriting that would allow a natural definition of model transformations for graph grammars. The lack of general second-order characterization presents difficulties for employing graph grammars as targets of model transformations, and studying how model transformations affect their natural behaviour. In this thesis we address the problem of modelling and analysing systems undergoing programmed modifications in the context of graph grammars. We use the generalization of the double-pushout approach for graph rewriting as a principle for defining simultaneously the system semantics and structural modifications. To achieve this, we introduce a notion of second-order graph rewriting that acts on graph transformation rules. Based on secondorder rewriting we are able to define second-order graph grammars, models equipped with a first-order layer, representing the original system execution, and a second-order layer, representing a model transformation. Using second-order graph grammar we can encode simultaneously model transformations and system execution, allowing us to formally relate them. Moreover, we propose new techniques to investigate the effect of rule modification over their effect on graphs. As an application example, we characterize aspect-oriented constructions for graph grammars, and discuss how to relate the aspect weaving layer with the base system semantics.

Abstract:

Graduating globally conscious citizens, prepared to lead in a global society and serve competently in their communities, is a mission for institutions of higher learning. Short-term study abroad programs with service-learning components have increased in favor toward exposing more students to international engagement, however, few studies explore socially responsible leadership development from these programs and fewer reveal participant perspectives. The purpose of the qualitative case study was to explore and interpret perceptions had by undergraduates and faculty leaders on socially responsible leadership development from participation in the short-term, faculty-led international service-learning component of a capstone course. Utilizing the Social Change Model of Leadership Development to guide the research and organize the findings allowed a thorough exploration of the constructs, identification of experiential learning and transformative learning, along with short-term international service-learning. Findings revealed engagement, reflection, and communication were integral to socially responsible leadership development as well as challenging bias and assumption, change in perspective, trust, skill contribution, global consciousness, and knowledge acquisition. A short-term, faculty-led international service-learning experience embedded within a capstone could develop socially responsible leadership in undergraduates thus influencing their global citizenship. Recommendations for practice include considering the maturity level and learning styles of participants to reduce disengagement and enhance learning and development for all students. Future research could document the longitudinal effect of short-term international service-learning on former participants’ socially responsible leadership.

Abstract:

In recent years, Europe has witnessed a flow of refugees from war struck areas who seek asylum in various European countries, where Sweden is one of the recipient country. A large portion of these refugees comprise of unaccompanied refugee minors (URMs). Aim: The aim of the present study is to examine how unaccompanied refugee minors have the conditions in Malmo when it comes to individual health and lifestyle (tobacco, alcohol and drug use) and social environment (absence of family, living situation, school, social support and future prospects) as compared to the general population of the same age; and also, if these conditions could possibly put them at a risk to encounter or commit a crime. Method: The data is collected using quantitative survey questionnaires distributed to URMs (N=30). The data of the general population has been obtained through Region Skåne. Results: The findings indicate that in comparison to the general population, URMs report high level of ill-health, tobacco use, access to narcotics and low social support, which are termed as risk factors. The institute of school, however, is termed a protective factor for the URMs, where they score almost equivalent to the general population in terms of school satisfaction and better than them in terms of help and support from the teachers. The implication of the findings are discussed further in the paper.

Abstract:

This Grounded Theory study explored the longer-term psychological effects of male perpetrated domestic violence from the perspectives of ten women survivors. On average, they had been away from abuse for eleven years. The findings indicate that in the longer-term, concerns for safety and fear-related responses continued to affect women's lives. Additionally, two distinct theories are depicted. 'Revisiting intimacy' relates to altered perspectives and approaches towards subsequent partnered intimate relationships. 'Re-establishing self-identity' reflects women's changed perceptions of self-identity, and how these issues were addressed over time. The processes described are not linear or sequential. Nevertheless, they suggest an on-going journey, with setbacks alongside breakthroughs, and some possibilities for resolving issues along the way. Being able to address self-blame associated with domestic violence was important. Furthermore, access to support, information and opportunities for selfdevelopment were relevant to improvements. Impediments to progress, such as unsuccessful help-seeking experiences are highlighted and implications for clinical psychology practice are discussed.

In this article intercultural education is discussed, cases from the Danish upper secondary school are analyzed, and some requirements for further development are proposed. First definitions of the concepts communication, communicative action, intercultural communication and intercultural education are given. Starting from these definitions it is argued that intercultural communication as well as intercultural education is possible. Then two cases are analyzed. Finally – in the Discussion – it is underlined that the students’ metareflection on the context dependence of the knowledge construction process is a pivotal precondition for successful intercultural education.

BACKGROUND: The prevalence of the pusher syndrome can affect patients' motor recovery after stroke (CVA). OBJECTIVES: To establish the prevalence of pusher syndrome in patients after stroke from clinical criteria contained in Contraversive Pushing Scale (evaluation of the symptom of pushing), and correlate them with neurological abnormalities, severity of stroke and functionality. METHODS: a cross-sectional study with convenience sample of patients of both sexes with a diagnosis of acute stroke. We included patients with clinically stable and able to assess the severity of the event from the range of NIHSS, Barthel (evaluation of the symptom of pushing). To diagnose the pusher syndrome used two scoring criteria with different cutoff points, pushing the Contraversive scale: result greater than or equal to 1 (criterion I) or greater than zero (criterion II).RESULTS: 86 patients were evaluated. Of these 30 met the inclusion criteria. 17 were men with mean age of 52.3 years. 26 patients had ischemic stroke and hemorrhagic stroke four. 14 had hemiplegia on the left and 16 right. Mean NIHSS and Barthel index were 8.5 and 48.8 points respectively. Using the criteria I and II prevalence rates were 3.3% and 26.6% respectively. The presence of pusher syndrome was significantly associated with lower values when the Barthel scale, we used the criterion II (22.5 ? 8.5 versus 58.4 ? 27.3, P <0.001). CONCLUSIONS: The prevalence of pusher syndrome in patients after acute stroke is significant and can vary according to the criteria used. Its presence is associated with clinical severity and functional dependence, higher incidence in ischemic stroke event, parietal lobe and middle cerebral artery, respectively.

Abstract:

Further Education (FE) colleges have been able to offer ‘direct entry’ to 14 to 16-year-old pupils since 2013, following the recommendations of the Wolf Report (2011). Currently, there are 17 FE colleges in the England offering this type of Alternative Provision (AP). Research focused on pupil transition into APs does exist, though most of this focuses on Pupil Referral Units (PRUs) or school-selected FE provision. A Systematic Literature Review (SLR) was conducted which showed a ‘gap’ in the research concerning 14 to 16 college provision in England. The aim of this research is to attempt to address this gap to a degree, and to gain an understanding of the experiences of young people who chose to make a ‘non-traditional’ transition into a 14 to 16 college. Classic grounded theory was selected as the methodology for this research (Glaser, 1978; Holton and Walsh, 2017). The aim of this research was to develop a substantive grounded theory of the experiences of participants ‘pushed out’ of mainstream who chose to transition to a 14 to 16 college. Qualitative data was collected initially through a focus group and five semi-structured interviews with purposively recruited target participants. The constant comparison method of grounded theory guided data collection and analysis. Theoretical sampling took place once a conceptual core category had emerged, resulting in data collection from four additional participants and re-interviewing an original participant. The main theoretical concepts emerging from the grounded theory methodology were: disempowerment and disengagement, agency through self-determination and re-empowerment. These theoretical concepts were linked within a theoretical framework drawing on transition models of self-determination theory (Ryan and Deci, 2000; Pierson et al, 2008) and bioecological systems (Trainor et al, 2008). The concepts of bounded agency (Evans, 2007) and ‘critical moments’ (Thomson et al, 2002) have been applied to explain how ‘pushed out’ participants were able to choose to make a ‘non-traditional’ transition to a 14 to 16 college. Implications for Educational Psychology practice have been discussed as well as areas for future research.

Abstract:

En génie logiciel, les méthodes modernes de développement (ex. le MDA) s'appuient de manière cruciale sur les notions de modélisation et de transformation. Ces méthodes peuvent s'interpréter à l'aide de la théorie des graphes. La difficulté théorique réside aujourd'hui dans l'ajout sur ces graphes de données supplémentaires sur lesquelles il est nécessaire de pouvoir effectuer des calculs. Notre travail s'est focalisé sur le développement d'un cadre mathématique sûr afin d'appliquer ces transformations. Les théories des catégories (à travers le double pushout) et des types inductifs (fonctions de calcul très expressives) nous ont permis de donner une solution unifiée à ce problème dans laquelle une seule opération permet de travailler sur la structure et de calculer avec les attributs en définissant des fonctions entre graphes possédant une partie contravariante pour le travail sur les attributs. De plus, les propriétés usuelles des systèmes de récriture sont vérifiées.

Este estudo teve como objetivo avaliar quatro técnicas de inserção de cimento resinoso na retenção de pinos de fibra de vidro à dentina radicular nos diferentes terços radiculares, bem como a nanoinfiltração nestes diferentes terços. As raízes de cinqüenta e dois pré-molares inferiores humanos extraídos foram tratadas endodonticamente e padronizado o preparo dos condutos. Assim, elas foram divididas aleatoriamente em quatro grupos, de acordo com a técnica de inserção do cimento: GC - seringa Centrix® com ponta fina; GL - broca Lentulo 35, GP - cimento aplicado diretamente no pino e GI - seringa para aplicação de insulina. Os pinos intra-radiculares (White Post DC - FGM) tiveram suas superfícies tratadas de acordo com o fabricante e foram cimentados de acordo com cada técnica. Após o armazenamento em água a 37° C por uma semana, para cada grupo, dez raízes foram seccionadas transversalmente em seis discos com 1 mm de espessura cada, e os terços coronário (TC), médio (TM) e apical (TA) do canal radicular foram identificados. O teste de push-out foi realizado a uma velocidade de 0,5 mm/min. Para avaliação da nanoinfiltração três raízes de cada grupo, ou seja, 6 discos por raiz, foram submetidos a imersão em Nitrato de Prata 50% para posterior obtenção de imagens feitas em microscopia eletrônica de varredura. As imagens foram analisadas por meio de software apropriado para obtenção das médias dos valores de nanoinfiltração convertidas em porcentagem. Os dados, submetidos a análise estatística por ANOVA 1 fator e Pós-teste Tukey (0,5%), mostraram que GC apresentou os melhores valores para resistência adesiva (MPa) e nanoinfiltração (%): 18,57 ± 4,19 e 37,70 ± 18,95 respectivamente, tendo GP o pior desempenho: 13,71 ± 1,61 e 65,11 ± 13,58 respectivamente. A técnica de inserção do cimento resinoso teve influencia nos valores de resistência adesiva e nanoinfiltração encontrados no estudo.
The aim of this study was to evaluate four techniques for insertion of resin cement on retention of glass fiber posts to root dentin in different root thirds, as well as these different nanoleakage in adhesive interface. The roots of the fifty-two human extracted pre-molars were endodontically treated and standardized preparation of the canals. It were divided into four groups according to the technique of insertion of the cement: GC - Centrix ® syringe with fine tip, GL - # 35 drill Lentulo, GP - cement applied directly to the post and GI - syringe for insulin delivery. The posts (White Post DC - FGM) had their surfaces treated in accordance with the manufacturer and were cemented according to each technique. After storage in water at 37° C for one week, each group of ten roots were sectioned transversely into six discs with 1 mm thick each, and coronal thirds (CT), medium (TM) and apical (TA) of root canal were identified. The push-out test was conducted at a speed of 0.5 mm / min. To evaluate the nanoleakage in the adhesive interface, three roots of each group, ie, 6 slices per root were submitted to immersion in 50% silver nitrate for subsequent obtaining of images made using scanning electron microscopy. Images were analyzed using appropriate software to obtain the mean nanoleakage values converted into percentage. The data were subjected to statistical analysis by ANOVA (one factor) and Tukey post-test (0.5%), showed that GC had the best values for bond strength (MPa) and nanoleakage (%):18,57 ± 4,19 e 37,70 ± 18,95 repectively and GP had the worst values: 13,71 ± 1,61 e 65,11 ± 13,58 respectively. The insertion technique of resin cement influenced on the bond strength values and on the nanoleakage found in the study.

Abstract:

Este trabalho aborda o estudo da aderência aço-concreto em pilares mistos preenchidos através de revisão bibliográfica e de investigação experimental. De modo esquemático, a aderência é dividida em três parcelas: adesão, aderência mecânica e atrito, que em conjunto compõem a aderência natural. Adicionalmente, podem ser empregados conectores de cisalhamento, que são dispositivos mecânicos fixados nas superfícies internas dos tubos, como meio de ampliar a resistência ao escorregamento. Foram realizados ensaios do tipo pushout em alguns tipos de modelos de pilar preenchido: modelos simples, com adição de conectores tipo pino com cabeça, com cantoneiras na interface aço-concreto e semelhantes aos anteriores mais elementos de ligação. Com os resultados obtidos traçaram-se comportamentos força x escorregamento do concreto, força x deformações axiais nos materiais e curvas de distribuição de força ao longo do comprimento dos modelos. Concluiu-se que conectores tipo pino com cabeça e cantoneiras são uma excelente alternativa como dispositivos auxiliares na transferência de tensões de cisalhamento na interface aço-concreto. Entretanto, é necessário garantir resistência à ligação para que esses mecanismos sejam mobilizados
This research presents a study of influence of bond on concrete-filled steel tubes by means of a bibliography review and an experimental investigation. The bond strength counts on three mechanisms: adhesion of the concrete to the steel surface, friction and wedging of the concrete core. In order to improve the shear resistance of the steel-concrete interface, shear connectors can be used. A series of push-out tests of rectangular concrete-filled steel tubes was conducted in the specimens without mechanical shear connectors, specimens with stud bolt shear connectors and specimens with angles. They were also tested the corresponding beam-column connections. The results are shown in curves force x slip of concrete, force x axial strain of materials and distribution of axial load to the steel and to the concrete. The results of the tests permitted identify the mechanisms of natural bond and indicated that the stud bolts and the angles are excellent alternatives as auxiliary mechanisms to transfer shear between the concrete and steel in the concrete filled composite column. However, it is necessary to guarantee the connection enough strength in order to permit these resistance be developed

Abstract:

Scholars for decades have studied the achievement gap and attempted to explain it in regards to race and class. Throughout the existing literature regarding the achievement gap between black and white students, however, there is a dearth of research exploring why the gap exists for upper-class black students; this population is largely ignored. This research seeks to explain why an achievement gap exists between white and black students who come from households of similar incomes. Ten students (five white and five black gradates) of a private, non-parochial school in Washington DC are interviewed about high school and post-high school experiences. Using cultural capital and labeling theory frameworks, this study follows the work of Billings (2011), Pattillo-McCoy (2000), Lacy (2007), and Khan (2011) in their focus on black students, cultural capital, and embodied privilege, and builds on that of Lensmire (2012), Dixon-Roman 2014, Orr (2003) Adams (2010) and Tyson et al. (2005). Results uncover the uniquely complex configuration of class and race. Latent issues as a result of race can arise, and the research illustrates how they affect the achievement ideology and attainment of both black and white students. This study’s findings suggest that two mechanisms shape the achievement gap: academic support and social interactions and interpretations, with the former rooted largely in class differences and the latter rooted in racial differences. This study aims to improve our understanding of the distinct role race and class play in influencing educational and professional outcomes from upper-class backgrounds.

Abstract:

Furnaces that heat metal parts (blooms) prior to hot-working processes such as rolling or forging are called pre-forming reheat furnaces. In these furnaces, the fundamental idea is to heat the blooms to a prescribed temperature without very large temperature gradients in them. This is to ensure correct performance of the metal parts subsequent to reheating. Due to the elevated temperature in the furnace chamber, radiation is the dominant mode of heat transfer from the furnace to the bloom. In addition, there is convection heat transfer from the hot gases to the bloom. The heat transfer within the bloom is by conduction. In order to design a new furnace or to improve the performance of existing ones, the heat transfer analysis has to be done accurately. Given the complex geometry and large number of parameters encountered in the furnace, an analytical solution is difficult, and hence numerical modeling has to be resorted to. In the present work, a numerical technique for modelling the steady-state and transient heat transfer in a reheat furnace is developed. The work mainly involves the development of a radiation heat transfer analysis code for a reheat furnace, since a major part of the heat transfer in the furnace chamber is due to radiation from the roof and combustion gases. The code is modified from an existing finite volume method (FVM) based radiation heat transfer solver, The existing solver is a general purpose radiation heat transfer solver for enclosures and incorporates the following features: surface-to-surface radiation, gray absorbing-emitting medium in the enclosure, multiple reflections off the bounding walls, shadowing effects due to obstructions in the enclosure, diffuse reflection and enclosures with irregular geometry. As a part of the present work, it has now been extended to include the following features that characterise radiation heat transfer in the furnace chamber · Combination of specular and diffuse reflection as is the case with most real surfaces · Participating non-gray media, as the combustion gases in the furnace chamber exhibit highly spectral radiative characteristics Transient 2D conduction heat transfer within the metal part is then modelled using a FVM-based code. Radiation heat flux from the radiation model and convection heat flux calculated using existing correlations act as boundary conditions for the conduction model. A global iteration involving the radiation model and the conduction model is carried out for the overall solution. For the study, two types of reheat furnaces were chosen; the pusher-type furnace and the walking beam furnace. The difference in the heating process of the two furnaces implies that they have to be modelled differently. In the pusher-type furnace, the heating of the blooms is only from the hot roof and the gas. In the walking beam furnace, the heating is also from the hearth and the blooms adjacent to any given bloom. The model can predict the bloom residence time for any particular combination of furnace conditions and load dimensions. The effects of variations of emissivities of the load, thickness of the load and the residence time of billet in the furnaces were studied.

Abstract:

O presente trabalho aborda análises de sistemas de propulsão e manobra para comboios fluviais, e seus efeitos na manobrabilidade dos comboios. Analisam-se o sistema de propulsão convencional (propulsor mais leme), o sistema azimutal e o equipamento de proa auxiliar combinado com cada um destes sistemas de propulsão. Apresenta-se a modelagem matemática dos sistemas de propulsão e manobra citados, os quais serviram de base para implementação de um simulador computacional utilizado para obtenção dos resultados desta dissertação. As forças e momentos hidrodinâmicos são obtidos através do método das derivadas hidrodinâmicas para as simulações próximas à velocidade de serviço do comboio, enquanto para simulações em baixa velocidade utilizou um método semi-empírico baseado no princípio de cross-flow. Inicialmente, efetuou-se a validação do simulador com resultados da literatura para o caso do comboio com propulsão convencional. Em seguida, o modelo foi adaptado para os demais tipos de sistemas de propulsão e manobra propostos. Os resultados obtidos mostram que há uma maior eficiência do sistema de propulsão azimutal e do equipamento na proa para manobras em baixas velocidades, o que se torna adequado sua aplicação em comboios fluvial, pois essas embarcações navegam em velocidades menores se comparadas a outros tipos de embarcações.
The present work deal with analysis of propulsion and maneuvering systems for pusher-barge system, and results on the maneuverability of convoys. It analyzes the conventional propulsion system (rudder plus propeller), the azimuth system and combined auxiliary equipment bow with each of these propulsion systems. Presents the mathematical modeling of propulsion and maneuvering systems mentioned, which served as the basis for implementation of a computational simulator used to obtain the results of this dissertation. The hydrodynamic forces and moments are obtained by the method of hydrodynamic derivatives for simulations about service speed, while for simulations at low speed used a semi - empirical method based on the principle of cross-flow. Initially, performed the validation of the simulation results with the literature for the case of pusher-barge system with conventional propulsion. Then the model was adapted to other types of propulsion and maneuvering systems proposed. The results show that there is a greater efficiency of azimuth propulsion system and equipment in the bow to maneuver at low speeds, which makes it suitable for application in river transport, because these vessels navigate slower speeds compared to other types of vessels.

Abstract:

La vérification et la validation des composants logiciels des systèmes temps réel est un des enjeuxmajeurs pour le développement de systèmes automatisés. Les modèles de tels systèmes doiventêtre vérifiés, et la conformité de leur implémentation par rapport à leur modèle doit être validée. Nous nous plaçons dans le cadre des systèmes récursifs temps réels modélisables par des automates à pile temporisés avec deadlines (TPAIO). Les deadlines imposent des conditions de progression du temps. L’objectif de cette thèse est de proposer des méthodes de génération de tests pour les TPAIO.Nos contributions sont les suivantes. Premièrement, une relation de conformité pour les TPAIO est introduite. Deuxièmement, une méthode polynomiale de génération de tests à partir d’un TPAIO déterministe avec deadline lazy est définie. Elle consiste à définir un algorithme de calcul d’un automate temporisé d’accessibilité incomplet en respectant les contraintes de pile. Cette méthode est incomplète. L’incomplétude n'étant pas un problème car l’activité de test est par essence incomplète. Troisièmement, nous définissons une méthode générant des cas de tests à partir d’un TPAIO déterministe avec sorties seulement et deadline delayable seulement. Elle d’applique aux abstractions de programmes récursifs temporisés. Elle consiste à générer des cas de tests en calculant un testeur sur-approximé. Finalement, nous avons proposé une généralisation du processus de génération de tests à partir d’un TPAIO général avec entrées/sorties et avec deadlines quelconques. La capacité de cette dernière méthode à détecter des implémentations non conformes est évaluée par une technique de mutation
The verification and validation of software components for real-time systems is a major challenge for the development of automated systems. The models of such systems must be verified and the conformance of their implementation w.r.t their model must be validated. Our framework is that of real-time recursive systems modelled by timed pushdown automata with deadlines (TPAIO). The deadlines impose time progress conditions. The objective of this thesis is to propose test generation methods from TPAIO.Our contributions are as follows. Firstly, a conformance relation for TPAIO is introduced. Secondly, a polynomial method of test generation from a deterministic TPAIO with only lazy deadlines is defined. It consists of defining a polynomial algorithm that computes a partial reachability timed automaton by removing the stack constraints. This method is incomplete. The incompleteness is not a problem because software testing is an incomplete activity by nature. Thirdly, we define a method for generating test cases from a deterministic TPAIO with only outputs and delayable deadlines. It applies to the abstractions of timed recursive programs. It consists of generating test cases by computing an over-approximated tester. Finally, we propose a generalization of the test generation process from a non deterministic TPAIO with any deadlines. Its ability to detect non conform implementation is assessed by a mutation technique

Movement of convoy/pushed convoy is its ability to change place due to certainforce that drives it. This force is created by ship’s propellers for given speed v=constand it should be equal to resistance of surrounding water and air. This is the reasonwhy useful force created by ships propellers (thrust) created by propellers of pushboatwhile navigating with a convoy at v=const needs to overcome not only theresistance of barges but push-boat’s resistance as well. For planers of transportprocess it is necessary to know, besides the resistance of surroundings duringnavigation of pushed convoys, the value of reduced and specific resistance for certaintypes of barges and convoys that they form. Apart from that methods for calculationof expected speeds of navigation, value of static load of engines based onexperimental research. Besides that new exploitation parameters for determination ofpush-boat’s work are proposed, which haven’t been used in Serbia. At the enddissertation presents methods to solve practical transportation tasks for differentships with different convoys.

Abstract:

The present study consisted of a phenomenological investigation of African American males who have been expelled from traditional educational settings in New Orleans, LA in order to provide educators with information geared towards increasing academic achievement in African American males. It has been noted that one of the reasons that Black males graduation rates are so low is because in addition to other factors that lead to non-completion, black males are more likely to be expelled from school. In this study, I used a Critical Race theoretical framework to explore gain experiential knowledge of these excluded young men, what they perceive as barriers to their success, and their sentiments on the relationships they have had with educators and peers whom they have encountered. Based on the participants’ responses, seven categories emerged from the data including: (a) Race and Racism, (b) Self Perceptions, (c) Family Expectations and Support, (d) Male Role Models and Mentors, (e) The School Environment, (f) School Discipline, and (g) Alternative School. Study participants described the totality of their education experiences by opening up about what they felt were key factors at play. The stories of the participants provided a deeper context of the nuances of racism and how it impacts their day to day educational experiences overall The results of this study provides data that may enable educators to begin steps to dismantle the school to prison pipeline by ensuring at-risk students are supported and successful in school without having to be removed. This information serves as a catalyst for future inquiry into additional nuances that effect the academic achievement of African American male students in K-12 schools.
