Metode Balancing Jig Procedure pada Tab Elevator Pesawat Boeing 737-800 untuk Mengurangi Dampak Flutter
Authors: Putra Lalu Giat Juangsa , Saputra Dian , Saputra Achmad Zahir
Published: August 2020

Primary flight control pada pesawat udara terdiri dari aileron, rudder dan elevator, Secondary flight control terdiri dari  flaps,  slats, spoiler dan  trim tab. Pesawat sebelum terbang harus dipastikan semua flight control dalam keadaan balance. Jika tidak, maka flutter akan terjadi ketika pesawat tersebut mengudara. Flutter adalah salah satu fenomena aeroelastisitas, yaitu fenomena getaran yang mengakibatkan  sayap   pesawat   terbang  “mengepak”  seperti   sayap   burung.  Hal   ini   diakibatkan karena kombinasi efek kekakuan struktur sayap, aerodinamika serta inersia (berat) dari struktur. Untuk menghindari terjadinya flutter harus dilakukan balancing flight control, salah satunya pada Tab Elevator. Tab elevator sering disebut dengan trim tab pada elevator. Trim Tab tersebut melekat pada elevator yang terletak pada horizontal stabilizer. Meskipun trim tab merupakan secondary flight control, harus tetap dipastikan balance. Cara balancing tab elevator adalah dengan metode jig procedure, dimana tab harus dilepas terlebih dahulu. Balance atau tidaknya tab elevator ditentukan dari nilai Tab Assembly Moment (TAM). Hasil yang didapat dari penelitian ini adalah 15.22 lbfinch dan tab dikatakan balance, karena menurut Structural Repair Manual (SRM) Boeing 737-800 range maksimal nilai TAM adalah 15.48 lbfinch. Jika pada penelitian didapatkan hasil lebih dari 15.48 lbfinch, maka tab harus dikembalikan ke paint shop untuk dilakukan pengelupasan beberapa lapisan catnya agar mengurangi beban tab tersebut. Apabila pengurangan beban pada tab tidak bisa dilakukan lagi, maka Tab tersebut dianggap reject (tidak layak) dan harus diganti dengan yang baru.

Published: August 2020

Wearable and wireless Electrocardiograph (ECG) enables real-time and long-term monitoring of heart rate (i.e. 24 hours). Several algorithms have been introduced to increase the accuracy of the heart rate calculation for this type of ECG. This study aims to compare the accuracy of two heart rate calculation algorithms: Filter-Based and Peak Threshold. Both algorithms were implemented into a wearable ECG prototype comprising AD8232, 8-bit microcontroller (ATMega328), and Bluetooth. ECG signals and heart rate (in Beat per Minute (BPM)) were sent via Bluetooth and displayed in real-time on a Windows-based application created using Visual C #. Experiments were conducted on 10 healthy subjects aged 20.4 ± 2.0 years and body weight of 60.8 ± 10.2 kg. The measurement results calculated by using Filter-Based and Peak Threshold were compared to a commercial wearable ECG (KineticTM) as a ‘ground truth’. The test results showed that the Filter-Based algorithm resulted in a more accurate calculation with the Root Mean Square Error (RMSE) of 1.53, compared to the Peak Threshold algorithm with RMSE of 2.69.

Beberapa tahun terakhir terjadi peningkatan kebutuhan sumber daya tegangan dc. Kebanyakan dari rangkaian elektronika daya pada sumber tegangan dc menggunakan full wave rectifier. Pemasangan nilai kapasitor yang cukup besar sebagai filter pada full wave rectifier dapat menyebabkan bentuk gelombang arus input menjadi tidak sinusoidal (terdistorsi). Perbedaan bentuk gelombang tegangan dan arus input berpengaruh pada besar kecilnya faktor daya. Interleaved Boost Converter (IBC) yang difungsikan sebagai Power Factor Correction (PFC) dengan menggunakan metode pengendali logika fuzzy diterapkan pada sistem untuk mencapai faktor daya mendekati unity. IBC bekerja pada discontinuous conduction mode (DCM). Saat rectifier menyuplai beban yang bersifat resistif maka arus input memiliki bentuk gelombang yang sefasa dengan gelombang tegangan input. Simulasi dan implementasi alat menggunakan beban yang bervariasi. Hasilnya IBC sebagai PFC dapat memperbaiki faktor daya dari 0.67 menjadi 0.93.

Contribuições da gramática do design visual para o ensino da leitura: sinalizações apontadas pela análise de uma campanha educativa
Authors: Scherrer Lara
Published: August 2020

O presente trabalho tem como escopo compreender como os diferentes modos de leitura influenciam na formação do professor. Diante das mudanças que vem ocorrendo em nossa sociedade e com as Tecnologias Digitais de Informação e Comunicação (TDIC) agregando cada vez mais elementos nas formas de comunicação, os modos de produzir e ler texto têm se diversificado, surgindo novos gêneros textuais. Assim, propõe-se   a analisar os efeitos de sentido advindos da composição imagética de uma campanha educativa veiculada em redes sociais. A realidade atual, em que o uso de imagens é cada vez mais recorrente, sobretudo por meio das novas tecnologias, requer que o professor se atualize e aprenda a manusear esses novos recursos. Para demonstrar como a imagem pode ser utilizada nas práticas escolares, foi analisada uma campanha educativa, no intuito de evidenciar a complexidade encontrada na compreensão dos textos não verbais. Para o embasamento-teórico dessa pesquisa, foi utilizada a Gramática do Design Visual (KRESS, VAN LEEUWEN, 2006), que possibilitou a análise de uma imagem a partir das metafunções representacional, interacional e composicional. Esse exame possibilitou a descrição de como os elementos verbais e não verbais se organizam de forma lógica e possuem uma combinação que possibilita a construção de sentidos. Por meio da análise, observou-se que, independentemente da área de atuação do professor, é imprescindível que ele saiba trabalhar com imagens e, assim, contribua para tornar o seu aluno um leitor proficiente, em momento em que o texto vem sofrendo reconfigurações, exigindo novas habilidades para o processo de leitura.
Por uma pedagogia latino-americana
Authors: Aparecida Ferraz Ribeiro Dulcineia , Barbosa Vanderlei
Published: August 2020

O presente artigo tem como objetivo refletir sobre a possibilidade de uma pedagogia latino-americana, comprometida com uma visão de formação integral do ser humano abrangendo os aspectos: epistemológico, pedagógico, político, filosófico, ético, estético, teológico, ecológico, místico e utópico. Baseada nessa perspectiva, a questão que orientou esse trabalho foi: Que tipo de formação humana contribuirá na adoção de práticas educacionais emancipatórias? A partir dessa inquietação foi realizado um estudo teórico-bibliográfico, da obra de Paulo Freire, partindo do livro Pedagogia do Oprimido (1988), complementando com outras obras mais recentes que descrevem o pensamento de Paulo Freire na América Latina. A análise das ideias freireana evidenciou que formar integralmente significa ter uma percepção do sujeito no mundo, com o mundo e em interação com o outro, concretamente situado numa realidade de opressão. Foram estabelecidas as inferências por meio de análises e interpretações em busca de novas descobertas em que obtivemos como resultados, uma possibilidade de formação humana e sua conexão com a Pedagogia Latino-Americana, bem como o anúncio de outras perspectivas práticas educacionais emancipatórias para um futuro possível.

We surveyed 19,052 individuals across all 50 states plus the District of Columbia. The survey was conducted on 10-26 July 2020 by PureSpectrum via an online, nonprobability sample, with state-level representative quotas for race/ethnicity, age, and gender (for methodological details on the other waves, see covidstates.org). In addition to balancing on these dimensions, we reweighted our data using demographic characteristics to match the U.S. population with respect to race/ethnicity, age, gender, education, and living in urban, suburban, or rural areas. This was the seventh in a series of surveys we have been conducting since April 2020, examining attitudes and behaviors regarding COVID-19 in the United States.Overall, support for voting by mail is quite high, with 64% of likely voters in our survey1 supporting making it easier to vote by mail, and only 23% opposing.Similarly, more Americans who say they plan to vote in 2020 support than oppose universal extension of vote by mail. A total of 66% of likely voters report that they would support giving every American the right to vote by mail in November, with 22% opposing.

NLRP7 expression associates with patient survival in high-grade serous ovarian cancer.
Authors: Mamoor Shahan
Published: August 2020

Ovarian cancer is the most lethal gynecologic cancer (1). We sought to identify genes associated with enhanced survival in high-grade serous ovarian cancer (HGSC) by comparing global gene expression profiles of tumors from women diagnosed with HGSC with the best and worst progression-free survival (2). We found significant differential expression of the gene encoding the NLR family pyrin domain containing 7 (NLRP 7) when comparing tumor transcriptomes based on progression-free survival. NLRP7 was expressed at significantly higher levels in high-grade serous ovarian tumors of women with the longest progression-free survival.
Risk compensation during COVID-19: The impact of face mask usage on social distancing.

To reduce the spread of Covid-19, governments around the world have recommended or required minimum physical distancing between individuals, as well as either mandating or recommending the use of face coverings (masks) in certain circumstances. When multiple risk reduction activities can be adopted, people may engage in risk compensation by responding to a reduced (perceived) risk exposure due to one activity by increasing risk exposure due to another. We tested for risk compensation in two online experiments that investigated whether either wearing a mask or seeing others wearing masks reduced physical distancing. We presented participants with stylized images of everyday scenarios involving themselves with or without a mask and a stranger with or without a mask. For each scenario, participants indicated the minimum distance they would keep from the stranger. In line with risk compensation, we found that participants indicated they would stand, sit or walk closer to the stranger if either of them was wearing a mask. This form of risk compensation was stronger for those who believed masks were effective at preventing catching or spreading Covid-19, and for younger (18-40 years) compared to older (over 65 years) participants.
The COVID States Project #6: Update on executive approval

Published: August 2020

The latest update to our executive approval series reveals a mix of continuity and change. The most obvious difference in the circumstances confronting the nation’s executives in the latest wave (July 10-26, 2020, N=19,052) compared to the prior wave (June 12-28, 2020) is that far more states are seeing increases in COVID cases than in early June. For instance, in the Northeast in our late June wave, all but one state (New Jersey) were trending downward in COVID cases relative to our early June wave. In late July, all but two states in the region are trending upwards in COVID cases. (New Jersey, ironically, represents one of the two improving states, with the second being Maine). Despite these worsening trends, many governors in the Northeast (excepting Maine, where Democratic Governor Mill’s approval rating stands at a middling 54%) remain quite popular, and have seen their approval ratings remain relatively stable (e.g. Massachusetts and Vermont) or increase (e.g., Rhode Island and Maine). Two governors in the region — Governor Murphy (D) of New Jersey and Governor Sununu (R) of New Hampshire — have faced substantial erosion in public support for their management of the pandemic since June, by 6 and 8 percentage points, respectively.

The unintended psychological and behavioral drawbacks of big push strategies

Published: August 2020

Governments and policy makers often adopt big push strategies to help under-developing regions achieve economic growth and shake off poverty. Although numerous studies have documented big push strategies’ positive impacts on indicators of economic development (e.g., poverty rate, unemployment rate, etc.), the current research presents evidence of serious psychological and behavioral drawbacks of such policies. Specifically, we examine China’s Great Western Development (GWD) Program as a recent prominent example of a big push strategy, in which about 370 million people receive preferential benefits while more than 1 billion people do not. Using a regression discontinuity design based on distance from the boundary of the GWD Program (+/- 100 km), we find that individuals residing in non-GWD regions report higher levels of psychological entitlement compared to their counterparts residing in GWD regions. As a result of increased psychological entitlement, these individuals engage in more selfish behavior and less prosocial behavior. Our results offer initial evidence of the unintended psychological and behavioral consequences of big push strategies.
The Right Tools for the Job: The Case for Spatial Science Tool-Building
Authors: Boeing Geoff
Published: August 2020

This paper was presented as the 8th annual Transactions in GIS plenary address at the American Association of Geographers annual meeting in Washington, DC. The spatial sciences have recently seen growing calls for more accessible software and tools that better embody geographic science and theory. Urban spatial network science offers one clear opportunity: from multiple perspectives, tools to model and analyze nonplanar urban spatial networks have traditionally been inaccessible, atheoretical, or otherwise limiting. This paper reflects on this state of the field. Then it discusses the motivation, experience, and outcomes of developing OSMnx, a tool intended to help address this. Next it reviews this tool's use in the recent multidisciplinary spatial network science literature to highlight upstream and downstream benefits of open‐source software development. Tool-building is an essential but poorly incentivized component of academic geography and social science more broadly. To conduct better science, we need to build better tools. The paper concludes with paths forward, emphasizing open-source software and reusable computational data science beyond mere reproducibility and replicability.
