Seismic Assessment of RC Frame Structure by Nonlinear Static Pushover Analysis.
Authors: Ahmed Syed Md Tajdik , Mishe Mishkat Zahan , Zahura Fatema-Tuz-
Published: July 2024

Bangladesh is located in a seismically active area, and the rising number of earthquakes has alarmed the local population. Major cities of Bangladesh are under a serious threat due to defective design and structural construction. If seismic do not take under consideration building could be severely damaged under seismic loads. Thereby, taking consideration into the alarming matter, BNBC, (2017) is an upgraded version of the previous code. BNBC, (2017) has provisions for both elastic and inelastic methods of analysis for structures under strong ground motion. BNBC, (2017) proposed an equivalent static load method to design the buildings; “which yields good results within the elastic limit but it cannot predict the nonlinear behavior of the structure beyond the elastic limit”. Pushover analysis, a nonlinear technique with a few approximations and simplifications, can predict the degree of damage caused by a seismic event. Pushover analysis was specifically proposed in ATC 40, (1996) and FEMA 356 (2000). The pushover analysis approach of ATC 40, (1996), as included in “ETABS,”(2017), has been examined in this study in an effort to show its efficacy and validity(KHAN, 2013).

Sensitivity of tropical orographic precipitation to wind speed with implications for future projections
Authors: Nicolas Quentin , Boos William R.
Published: July 2024

Abstract. Some of the rainiest regions on Earth lie upstream of tropical mountains, where the interaction of prevailing winds with orography produces frequent precipitating convection. Yet, the response of tropical orographic precipitation to the large-scale wind and temperature variations induced by anthropogenic climate change remains largely unconstrained. Here, we quantify the sensitivity of tropical orographic precipitation to background cross-slope wind using theory, idealized simulations, and observations. We build on a recently developed theoretical framework that predicts enhanced seasonal-mean convective precipitation in response to cooling and moistening of the lower free-troposphere by stationary orographic gravity waves. Using this framework and convection-permitting simulations, we show that higher cross-slope wind speeds deepen the penetration of the cool and moist gravity wave perturbation upstream of orography, resulting in a mean rainfall increase of 20–30 % per m s−1 increase in cross-slope wind speed. Additionally, we show that orographic precipitation in five tropical regions exhibits a similar dependence on changes in cross-slope wind at both seasonal and daily timescales. Given next-century changes in large-scale winds around tropical orography projected by global climate models, this strong scaling rate implies wind-induced changes in some of Earth's rainiest regions that are comparable with any produced directly by increases in global mean temperature and humidity.
Modeling home property listings’ time-on-market duration and listing outcome using copula-based competing risk method
Authors: Liu Yicong , Shakib Saeed , Miller Eric J. , Habib Khandker Nurul
Published: July 2024

Modeling housing market dynamics is an important component of land use and transport interaction (LUTI) models, particularly for microsimulation models and how they handle the market clearance mechanism. However, most of these models include key assumptions not derived or validated through empirical testing, such as when and what action a seller would take if a property could not be sold within an expected time. However, these are key decision elements of the housing market clearance process.
To fill this research gap, this study uses real estate sale listing data to investigate the factors influencing a property listing’s time-on-market (TOM) duration, listing outcome, and correlation. A copula-based structure is developed to jointly estimate the TOM and listing outcome through a competing hazard duration model and a nested logit model. The results show statistically significant and positive correlations between the TOM of terminated listings and termination choices (i.e., whether the terminated listing will be withdrawn from the market, converted to a lease, or re-listed as a sale). This implies that the unobserved factors that may increase a seller’s probability of terminating a listing would decrease its TOM duration until the termination. It is also found that an increase in the asking price of a property listing can significantly increase its TOM duration and probability of being terminated. The copula-based joint model can be integrated into a LUTI microsimulation framework to parameterize the maximum TOM duration of each simulated property for sale in the housing market, improving its market-clearing process to represent real-world behavior better.
Enhancing dynamic origin-destination (OD) matrix estimation for large networks through feature engineering: A comprehensive framework
Authors:   , Sharma Shubham
Published: July 2024

This thesis proposes novel algorithms for the efficient online estimation of dynamic travel demand in large-scale urban transport networks. Dynamic travel demand refers to the number of people travelling between various zones in a city at different times of the day, captured using Origin-Destination matrices. This data is vital for understanding travel behaviour, optimizing traffic flow, and reducing congestion. However, their estimation for large networks is computationally challenging. This thesis developed a novel framework that leverages historical data and machine learning to reduce the computational requirements of the estimation process and improve accuracy, enabling design of better traffic management strategies.
(D)écrire un oubli. Bakary Diallo, tirailleur et poète
Authors: Ellena Samuele
Published: July 2024

Force-Bonté est le premier roman à avoir été publié en France par un Africain subsaharien. Bakary Diallo y retrace son expérience en tant que tirailleur sénégalais pendant la campagne au Maroc, la Grande Guerre et la période de l’entre-deux guerres. J’en propose une étude historique structurée en trois parties. L’effacement de cette œuvre pionnière de l’histoire littéraire africaine est justifié par des critères idéologiques, mais le doute concernant la paternité de l’œuvre n’a pas de fondement. En outre, l’article souligne le contexte discursif dans lequel Bakary Diallo prend la parole afin de mettre en valeur la perturbation de la représentation stéréotypée et réifiante des tirailleurs, telle qu'elle était dominante dans l’Europe de 1926, année inaugurale de la littérature africaine d’expression française.

Область автоматического распознавания речи активно развивается в рамках машинного обучения и становится важным инструментом для управления различными устройствами и автоматизации систем. Однако большинство таких систем преимущественно нацелены на работу с речью взрослых, в результате чего потребности детей остаются без внимания. Особенности детского голоса и его развитие повышают риск ошибок при распознавании детской речи, особенно когда используются приложения, разработанные и тренированные на взрослых голосах. К тому же, многие приложения не учитывают уникальность детской речи и характеристики языка, который дети используют в общении как с ровесниками, так и со взрослыми. Кроме того, ощущается недостаток данных для языков агглютинативной группы, таких как тюркские языки, что затрудняет сбор достаточного и качественного корпуса. В данной работе рассматриваются подходы к распознаванию детской речи с применением данных, адаптированных для взрослых, и их влияние на точность распознавания казахского языка. Изучены две модели: коннекционная временная классификация и архитектура с механизмом внимания и моделью вставок. Несмотря на то, что результаты являются обнадеживающими, в будущем потребуются дополнительные улучшения и расширение корпуса с записями детской речи.

Предметом исследования является проектирование и технология изготовления композитных волоконно-оптических датчиков. Они используются в режиме жесткой эксплуатации. Суть задачи заключается в исследовании конструкции и совместимости оптических и микромеханических свойств для одновременного измерения нескольких физических величин. В этом отношении выбранный метод модульного преобразования решает проблему комбинированности измерения. Разработанная конструкция и технология электрического соединения значительно снижают внутренние механические напряжения датчика и повышают стабильность работы комбинированного датчика в экстремальных условиях эксплуатации. Аналитические модели, связывающие величину и ориентацию внутренних механических напряжений с характеристиками временной устойчивости для сложных конструкций, как правило, отсутствуют. На практике полученные результаты исследований могут быть применены к комбинированным датчикам давления и температуры, давления и вибрации и т.д.

На сегодняшний день наблюдается астрономический рост объема данных, связанных с информационными потоками от различной деятельности человека. Все увеличивающийся объём пропускаемой информации создаёт для опорной сети передачи данных определенную сложность при её обработке. С другой стороны, современное общество требует высоких скоростей передачи обработанной информации. Исследование реально измеренных данных показывают, что они обладают неравномерной интенсивностью поступления пакетов на обслуживающие сетевые устройства. Модели, созданные на основе данных, описывающих изменения одного объекта в разные моменты времени (временные ряды), обычно проявляют не стационарность, что свидетельствует о многокомпонентной структуре этих данных. Выявить и количественно выразить компоненты сложной структуры – наличие/отсутствие тенденции, периодичности, случайной компоненты является основной задачей анализа временного ряда. В ходе анализа временных рядов крайне важно выявить, является ли ряд стационарным или нестационарным, поскольку они обладают различными статистическими характеристиками и, следовательно, требуют различных методов оценки [1-3]. В данной работе проведена проверка на случайный процесс временного ряда, основанного на фактических данных, полученных с магистрали в городе Алматы, (Казахстан). Для исследования временного ряда использованы методы автокорреляции, дифференциации, применены статистические тесты для определения случайного процесса, который является одним из факторов не стационарности ряда.

Қазіргі уақытта өнеркәсіптің қарқынды өсуі байқалады, бұл электр энергиясын тұтынудың артуына әкеледі. Бұл электр энергиясын өндірудің ұлғаюына және электр станцияларында электр энергиясын өндіруді, қосалқы станциялардың қарқынды құрылысы жолымен жүретін электр энергетикалық жүйелердің дамуымен қатар жүреді. Электр энергетикасының тұрақты дамуы электрмен жабдықтау мен электр энергиясының сапасын жақсарту қажет екендігіне алып келеді. Ол үшін жаңа энергетикалық нысандар салу немесе ескілерін қайта құру қажет. Электр энергетикалық жүйелердің қосалқы станцияларын жобалау – бұл электр жабдықтарының құрамы, электр қосылыстарының негізгі тізбектері, тарату құрылғыларының орналасуы мен конструкциялары, өлшеулер, релелік қорғаныс және автоматика бойынша техникалық шешімдерді әзірлеу мен қабылдаудың күрделі үрдісі болып табылады. Сондықтан жаңа нысанды салу қайта құруға қарағанда әлдеқайда қымбатқа түседі. Қайта құру ескі жабдықты жаңа параметрлер бойынша тексеруді, осы параметрлерге сәйкес келмейтін немесе моральдық және физикалық тұрғыдан ескірген жабдықты ауыстыруды қамтиды. Бұл ғылыми жұмыстың мақсаты трансформаторлық қосалқы станцияларды жобалау, қайта құру принциптерін түсіну және игеру, сондай-ақ олардың белгіленген режимдерін есептеу және талдау әдістерін игеру болып табылады. Трансформаторлық қосалқы станциялар электр энергиясын қабылдауға, түрлендіруге және таратуға қызмет етеді.

Desarrollo de Talentos en el Tenis – Hablar el Idioma
Authors: Roetert Paul , Kovacs Mark , Crespo Miguel
Published: July 2024

Cuando se profundiza en cualquier área de estudio nueva o diferente, una de las primeras cosas que hay que hacer es familiarizarse con la terminología adecuada. Probablemente nadie se sentiría a gusto tomando clases de tenis con alguien que hablara de “golpe desde la izquierda” en lugar de “revés” o que confundiese “voleas” con “remates”. Obviamente, nos cuestionaríamos la credibilidad de ese profesor. El mismo concepto se aplica para el desarrollo de talentos; existe cierta confusión con respecto a lo que realmente significa. Sin embargo es muy importante, que nosotros, entrenadores de tenis, comprendamos no solamente la terminología adecuada sino también los conceptos subyacentes, particularmente en lo que atañe al correcto desarrollo de nuestros jugadores. Veamos lo que existe actualmente en la literatura científica sobre este tema.

Authors: Pereira João Dimitri Rodrigues , Reis Maria Eduarda Guimarães , Medeiros José Rômulo de , Silva Bruno Frota Amora , Viana Fernando André Campos
Published: July 2024

In the current context, orofacial harmonization can serve as a complementary means to treat deformities, whether from an aesthetic or functional perspective. In this scope, the present study aims to evaluate the use of hyaluronic acid fillers and botulinum toxin in correcting facial defects. This study consists of a literature review based on the determination of the theme, using the databases PubMed, EBSCO, SciELO, and Google Scholar. The temporal delimitation was established from 2018 to the present. The MeSH descriptors used in the research were: "hyaluronic acid filler," "facial abnormalities," and "augmentation," adding respective descriptors for each topic (ocular, nasal, ear, and lip palate oral). Data were collected between March and April 2023. A final sample of eight articles was obtained, based on the inclusion criteria adopted, with the highest number of publications identified in 2021 (n=3; 37.5%). All the results were in English, predominantly from the PubMed and Google Scholar databases. Regarding the type of facial deformity, it was observed that cleft lip and palate and chin deformity were the majority of the studies analyzed. In terms of the type of orofacial harmonization approach, hyaluronic acid injection was the most used method. Therefore, it was concluded that orofacial harmonization can assist in the rehabilitation of patients with some facial deformity, whether congenital or acquired, thus being a viable treatment option for patients with facial deformities.
A Review on the Role of some Cardioprotective Natural Resources in Mitigating Doxorubicin-Induced Cardiotoxicity
Authors: Pal Rohan , Subhra Saha Rajat , Dey Sudipta , Das Sumana
Published: July 2024

As an effective and widely used anti-cancer medication, doxorubicin (DOX) also has the side effect of causing dose-dependent organ toxicity, primarily cardiotoxicity. Recent research has shown that the main pathogenic factors causing cardiomyopathy are oxidative stress, inflammation, and consequent cardiomyocyte death. Due to the shortcomings of currently available adjuvants in terms of pharmacoeconomics, short-term efficacy, and inherent adverse effects, the clinical application of classical cytotoxic medicines continues to be a preferred mode of treatment for cancer. As anticancer, chemopreventive, and cardioprotective agents, numerous dietary plants and mushrooms of natural origin have recently attracted interest. The current analysis provides an overview ofthe cardioprotective effect of some naturally occurring resources against experimental model-induced cardiotoxicity caused by DOX. Additionally, the review article covers the geographical availability, biological source, chemical constituents, and pharmacological actions associated with the pharmaceutical development of natural resources and their prospective application for additional drug development. These substances could be a valuable source of alternative adjuvants for chemotherapy used in medication development that are optimal, affordable, and safe.

Skin cancer is a leading cause of cancer-related mortality and disability worldwide. Nanoparticles may one day provide a highly targeted and effective means of combating skin cancer. This review article discusses nanoparticles' existing use, limitations, and prospects in skin cancer treatment. The data came from studies, reviews, and academic articles published within the previous five years. Thanks to nanoparticles, improved medication delivery, more individualized therapies, and more precise imaging techniques are all possible. Chemotherapy, targeted therapies, and combination medications all use nanoparticles like liposomes and dendrimers made of metals. Despite the positive results, there are still obstacles to overcome, such as bioavailability, toxicity, and regulatory hurdles. The review draws attention to these problems and stresses the necessity for further study and multidisciplinary cooperation. One way to treat skin cancer more thoroughly is to use multifunctional nanoparticles or to combine nanoparticles with emerging technologies such as immunotherapy and CRISPR. Researchers, physicians, and policymakers interested in using nanoparticles to treat skin cancer may find this helpful work.
