The controller should receive, in ground, the programmed route; the model should answer to the pilot commands, within a visual range when operating in the aided mode, and should go through the programmed route in the autonomous mode, after confirmation of the pilot. After reaching the end of the programmed route, the model airplane should return to the starting point, keeping the maximum flight level of the route as the reference height. The model airplane will carry in a communication system to allow the monitoring process from a ground station, able to keep updated the airworthy conditions, as well as the level of accuracy between the actual and the planned route. The communication may be carried out directly using a radio link, with the receiver allocated in a mobile ground station, monitored by a pilot, to make higher the security level. However, the model airplane may transfer the data through a GPRS link, connected to the web system, which transfers the data to the ground station. In this case, the ground station must be connected to the web.The route saved in the model control system is built based on online maps directly linked by the software for the mission programming and monitoring, which can carry out the treatment and storage of the model data and parameters. The programming of the stability control and route, with primary data of latitude, longitude and height allows the real time monitoring of the model, related to the planned route and throught images captured by embedded video cameras. All data are storage following a timeline process, such that they can be recovered for futher analysis. / Esta disertação da área de engenharia elétrica consiste na construção de um sistema de controle completo de hardware e software para controle de um aeromodelo de asa fixa e/ou asa móvel, de maneira a implementar um piloto automático compatível com as necessidades de voo autônomo ou assistido, sendo que tal sistema deverá ser compatível com a precisão de voo aplicada a monitoramento de sistemas críticos.O sistema é constituído por uma placa controladora composta por hardware e firmware específicos, capaz de controlar um modelo orientado por coordenadas GPS, para que o mesmo percorra uma rota predeterminada e retorne ao ponto de partida de forma autônoma. A placa recebe, ainda em solo, a programação da rota a ser percorrida; o aeromodelo deve responder normalmente aos comandos do controle remoto do piloto em solo, respeitando o raio de alcance visual do piloto no modo assistido e segue a rota programada no modo autônomo após confirmação de comando do piloto. No final do percurso o aermodelo volta em trajetória reta para o ponto de partida, respeitando a maior altura do trajeto. O aeromodelo deve ser munido de sistema de comunicação para o devido acompanhamento em solo das condições de aeronavegabilidade do aeromodelo em voo, bem como a verificação dos níveis de precisão em relação à rota programada. A comunicação pode ser feita diretamente por sistema de link de rádio, direcionada a um terminal móvel em solo, que é acompanhado pelo piloto, para aumentar o nível de segurança, mas o aeromodelo também pode comunicar por rede de celular GPRS, conectado à internet, que direciona os dados ao terminal em solo. Nesse caso, o terminal, também deverá estar conectado à internet. A rota programada no aeromodelo é construída com base em mapas online conectados diretamente ao software de programação e acompanhamento de missão, que faz o tratamento e armazenamento dos dados e parâmetros do aermodelo. Tanto a programação de controle de estabilidade, quanto de rota, com dados primários relativos a latitude, longitude e altura, permitem o acompanhamento em tempo real do aeromodelo junto à rota programada e também através da imagem da câmera de gravação embarcada no aeromodelo. Todos os dados são gravados com base em processo de linha do tempo, que podem ser recuperados em conjunto para análise posterior.

This district, occupied from its beginning by high income population, was one of the last frontiers in the expansion of the city. The intensifi cation of its occupation started in the 1970 s, after the implementation the Pilot Plan, elaborated in 1968 by architect Lúcio Costa, according to the premises of Modern Urbanism. Urban planning, associated with the action of the real estate market and the increase in the urban violence, resulted in the decline of the urban nucleus established by Costa and the appearance of the gated communities − in the 1980 s − as the top real estate product. This model of dwelling, characterized by isolated towers in large stretches of land, with vast green areas and leisure facilities, turned the district into the carioca anti-city. resently, Barra da Tijuca is still one of the main areas of expansion in Rio de Janeiro and is a reference in big private developments focused on the high income population. / Esta dissertação trata do surgimento do condomínio residencial fechado − fenômeno da cidade contemporânea − no bairro Barra da Tijuca, localizado na zona oeste do Rio de Janeiro. O bairro, ocupado desde o início pela população de alta renda, foi uma das últimas fronteiras de expansão da cidade. A intensificação de sua ocupação só ocorreu a partir da década de 1970, após a implementação do Plano Piloto elaborado em 1968 pelo arquiteto Lúcio Costa, conforme premissas do Urbanismo Moderno. O planejamento urbano associado à ação do mercado imobiliário e ao aumento da violência urbana propiciou o declínio do núcleo urbano estabelecido por Costa e o surgimento do condomínio residencial fechado − na década de 1980 − como o produto moradia a ser explorado. Esse modelo de habitação, pautado na implantação de torres isoladas em grandes glebas, com amplas áreas verdes e de lazer, caracterizou o bairro como a anticidade carioca. Atualmente a Barra da Tijuca se mantêm como uma das principais áreas de expansão do Rio de Janeiro e é um referencial no que diz respeito aos grandes empreendimentos privados voltados para a população de alta renda.

勞動基準法第八十四條之一適用要件之探討─以航空業為例 / A study of requirements for article 84-1 of the labor standards law- An example of the aviation

王世明, Wang, Shi Ming Unknown Date (has links)
航空業空勤組員適用勞基法第八十四條之一過去至今爭議不斷,而2016年華航空服員罷工行動的七大訴求中空勤組員回歸勞基法的議題再次被提出討論,時至今日這項訴求尚未獲得航空公司與政府的正面回應,抗爭凸顯台灣空勤組員可能存在工作時間過長且休息不足的問題。因此本研究首先探討國際勞動公約、台灣與日本的工時適用例外法理,而後透過深度訪談了解空勤組員的工時狀況與勞基法第八十四條之一的實施現況而提出立法政策的建議,最後,再參考日本的航空公司的營運經驗,分析本文所提出的立法政策是否具有可行性。 本文經由工作時間法理的探討,認為我國的空勤組員並不完全符合工時適用例外法理的要件,簡言之,不該將全數組員納入勞基法第八十四條之一的適用對象,既使政府基於企業的需求,允許單一航段工作時間超過十二小時的越洋航線可以適用勞基法第八十四條之一,那對於適用對象與執行的勤務應有明確的限制,只有經營國內線與區域航線的公司既該排除於適用對象之外,而非將所有空勤組員納入勞基法第八十四條之一,此外,必須嚴格落實同法第二項的但書規定,不得讓勞資雙方訂定有損勞工健康與福祉的勞動條件,或者透過立法進一步要求雇主應主動提供維護健康的措施,以確保勞工在長工時的情況下,仍然可以維持健全的身心狀態。 關於立法政策建議的可行性,從日本的經驗可得而知,既使空勤組員回歸勞基法,飛航勤務仍然可以順利運作,且有機會減少因將所有組員納入勞基法第八十四條之一而徒增的人事成本,對於公司而言可以獲得較佳的勞務成效進而提升飛航安全,同時又可以消除空勤組員過勞所產生的壓力與改善勞資關係。 / There is a huge controversy over the flight crew applying to Article 84-1 of the Labor Standards Law. In the seven demands of China Airlines flight attendant strike in 2016, the issue of flight crew applied to Labor Standards Law was again discussed. Now this appeal has not yet received a positive response from the airlines and the government. The protests highlight that Taiwan's flight crew may have problems with long working hours and lack of rest. Therefore, the first part of this study is to understand the working hours of flight crew and implementation status of Article 84-1 of Labor Standards Law. According to the International Labor Convention, Taiwan and Japan's theories of working hours, then propose legislative policy. Finally, reference to the Japanese airline's operating experience, whether the legislative policy proposed in this article is feasible. According to theories of working hours, think the flight crew do not meet the requirements of Article 84-1 of the Labor Standards Law. It should not be included in the application of Article 84-1 of the Labor Standards Law. Even if the government is based on the needs of the business, let a single section of the working hours of more than 12 hours of cross-ocean routes applying to Article 84-1 of the Labor Standards Law. There should be a clear limitation on the applicable object and the service to be performed. Exclude companies that operate only domestic and regional routes. In addition, the provisions of Article 84-1.(2) of the Labor Standards Law must be strictly implemented. It is forbidden for employers and employees to set conditions for working that impair the health and well-being of workers. Or through legislation further require employers should take the initiative to provide health maintenance measures. To ensure that workers can still maintain a healthy physical and psychological condition when they are long working hours. On feasibility of legislative proposals, even if flight crew apply the Labor Standards Law, flight service can still operate smoothly, it is known from Japan's experience. And have the opportunity to reduce personnel costs, because all of the flight crew applying to Article 84-1 of the Labor Standards Law. For the company can get better service performance and thus enhance flight safety. At the same time, it can eliminate the pressure caused by overwork of flight crew and improve the labor-capital relations.

An Experimental Study to Improve the Casting Performance of Steel Grades Sensitive for Clogging

Svensson, Jennie January 2017 (has links)
In this study, the goal is to optimize the process and to reduce the clogging tendency during the continuous casting process. The focus is on clogging when the refractory base material (RBM) in the SEN is in contact with the liquid steel. It is difficult or impossible to avoid non-metallic inclusions in the liquid steel, but by a selection of a good RBM in the SEN clogging can be reduced.   Different process steps were evaluated during the casting process in order to reduce the clogging tendency. First, the preheating of the SEN was studied. The results showed that the SEN can be decarburized during the preheating process. In addition, decarburization of SEN causes a larger risk for clogging. Two types of plasma coatings were implemented to protect the RBM, to prevent reactions with the RBM, and to reduce the clogging tendency. Calcium titanate (CaTiO3) mixed with yttria stabilized zirconia (YSZ) plasma coatings were tested in laboratory and pilot plant trials, for casting of aluminium-killed low-carbon steels. For casting of cerium alloyed stainless steels, YSZ plasma coatings were tested in laboratory, pilot plant and industrial trials. The results showed that the clogging tendency was reduced when implementing both coating materials.   It is also of importance to produce clean steel in order to reduce clogging. Therefore, the steel cleanliness in the tundish was studied experimentally. The result showed that inclusions originated from the slag, deoxidation products and tundish refractory and that they were present in the tundish as well as in the final steel product. / VINNOVA

VR-flygsimulatorer, för ökad upplevelse och som läroverktyg i flygutbildningar / VR flight simulators, for enhanced experiences and as a pilot training tool

Eliasson, Carl, Hedberg, Alexander January 2017 (has links)
Virtual reality (VR) är ett begrepp som blivit allt mer välkänt de senaste åren. VR kan beskrivas som en datorgenererad virtuell omvärld som användaren omsluts av. VR-miljön upplevs genom människans sinnen såsom syn, hörsel och känsel.Syftet med examensarbetet är att undersöka hur realistisk en kommersiellt tillgänglig VR-flygsimulator upplevs av piloter och undersöka om VR-teknik kan vara ett användbart läroverktyg för t.ex. flygskolor. VR-tekniken har under de senaste åren utvecklats väldigt mycket vilket gjort att många av de implementations svårigheter som VR-tekniken inneburit till stor del lösts. Nya helintegrerade head mounted displays (HMD) med inbyggd kompatibilitet gör att integreringsproblemen nästan helt försvunnit. Eftersom VR-tekniken nu är mer tillgänglig och lätthanterlig ligger det helt rätt i tiden att undersöka hur VR-teknik kan användas inom flygbranschen.Metoden för examensarbetet inleddes med informationsinsamling om VR-teknik och traditionella flygsimulatorer. Utifrån denna information skapades sedan en undersökning som bestod av två delar. Den första delen var ett experiment med en VR-flygsimulator och den andra delen var en intervju som utfördes direkt efter experimentet. Sju stridspiloter deltog i undersökningen.Resultaten av undersökningen visar att VR-flygsimulatorer upplevs som mer realistiska jämfört med traditionella flygsimulatorer. Undersökningen tyder också på att VR-teknik kan vara ett bra läroverktyg om de problem som identifierats lösts på ett tillfredsställande sätt. / Virtual reality (VR) is a rising phenomenon that has skyrocket in popularity the past year. VR is often referred to as a computer generated virtual environment the user gets immersed in. The VR environment is experienced through different types of sensory stimuli.The purpose of this thesis is to examine how realistic a commercially available VR flight simulator is being perceived by real pilots as well as examine if VR technology could be a viable educational tool for flight schools. The motivations of this thesis are the facts that the VR-technology has advanced in a quick phase. Many of the past difficulties with implementing VR technology have been addressed with new fully integrated head mounted displays therefor capability issues are no longer a big problem. Because of the simplicity of new VR-systems it’s a good time to investigate VR uses and how it compares to traditional flight simulator techniques.The method used for the thesis started with collecting information about VR technology and traditional flight simulators. With that information a survey consisting of two parts was created. The first part was an experiment with a VR flight simulator, and the second part was an interview conducted directly after the experiment. Seven jet fighter pilots participated in the survey.Our results show that a VR flight simulator is perceived as more realistic compared to a traditional flight simulator. It is also shown that VR technology could be a good educational tool if some of the issues that were found are resolved or improved upon.

Efficacy of a community-based infant hearing screening program in the Western Cape

Friderichs, Niki 03 December 2012 (has links)
Apart from isolated programs in private and public health care sectors, South Africa has no existing systematic public infant hearing screening program at community level. As a result, early identification of hearing loss is certainly not being attained for the majority of infants in South Africa with far-reaching effects for individuals, families and society at large. Screening programs at primary health care immunization clinics have been proposed as an alternative to hospital-based programs in South Africa. The objective of this study was to evaluate the first systematic community-based infant hearing screening program in a developing South African community in the Western Cape. A combined descriptive and exploratory research methodology was followed incorporating aspects of a program evaluation design. The study was of a quantitative nature and the required data were collected by means of a questionnaire and OAE testing conducted by clinic nurses on subjects. A community-based universal infant hearing screening program initiated at eight primary health care clinics in the Cape Metropolitan area was evaluated over a 19-month research period. During this time 6227 infants who were candidates for screening attended their 6, 10 or 14-week immunization visit at the relevant clinic. Clinic nurses were trained as screening personnel. A two-stage distortion product otoacoustic emissions screening protocol was utilized. The target disorder for this study was bilateral permanent congenital and early onset hearing loss and infants referring the first screen were scheduled for a 4-week follow-up visit at the clinic. Diagnostic audiological and medical evaluations were scheduled at referral hospitals when indicated. The study evaluated the efficacy of the program based on coverage, referral and follow-up rates and diagnostic outcomes according to guidelines specified by the Health Professions Council of South Africa 2007 Position Statement. Overall coverage rate across the eight clinics was 32.4% with 2018 infants (aged 0- 14 weeks) screened. The mean age of the sample at first stage screen was 3.9 weeks of age and 13.5 weeks of age for first hospital visit. Overall first stage screen referral rate was 9.5% with 62 subjects (3%) referred for diagnostic services at hospital level after a follow-up screen. The average follow-up rate for rescreens at clinic level was 85.1% and for initial diagnostic assessments at hospital level it was 91.8%. Although minimal hearing loss was not the primary focus of the screening program the outcomes did include those subjects with fluctuating conductive hearing loss and permanent unilateral hearing loss. Prevalence rates were 4.5/1000 with significant hearing loss, including sensorineural (1.5/1000) and conductive (3/1000) losses, and 12.9/1000 for subjects with middle ear effusion.<p-> The community-based infant hearing screening program was valuable in attaining high follow-up return rates but reaching sufficient coverage may require dedicated screening personnel as opposed to existing nursing personnel. Furthermore, consideration of an alternative community-based platform such as midwife obstetric units may improve coverage and referral rates and prevalence of permanent congenital and early onset hearing loss. / Dissertation (MCommunication Pathology)--University of Pretoria, 2013. / Speech-Language Pathology and Audiology / Unrestricted

Papugová, Tereza January 2013 (has links)
Special Economic Zones have been a popular instrument for fostering economic growth. The SEZ's main aim is to attract foreign investors into the country, thus providing necessary capital for economic development. Diploma thesis focuses on application of this approach in China and provides analysis of origin, economic situation and future prospects of these areas. At first, the concept of special economic zone is theoretically defined for the further usage in chinese context. Thesis also offers a comparison with export processing zones and SEZs in India to provide a broader perspective of the concept of special economic zones in the world. Hereafter, the development and performance of SEZs in chinese provinces Guangdong, Fujian and Hainan are presented. Furthermore, the current challenges for the zones to face are identified. Those challenges will be crucial for zones to cope with in order to keep up the pace with today's trend of liberalisation and international cooperation in the worldwide economy.
