摘要: As climate change accelerates, societies and climate-sensitive socioeconomic sectors cannot continue to rely on the past as a guide to possible future climate hazards. Operational decadal predictions offer the potential to inform current adaptation and increase resilience by filling the important gap between seasonal forecasts and climate projections. The World Meteorological Organization (WMO) has recognized this and in 2017 established the WMO Lead Centre for Annual to Decadal Climate Predicti

摘要: Brake parachutes play an important role in aircraft landings as they are designed to slow down the speed of an aircraft. The brake parachutes are effective, especially for landing on the slippery surface during the regular and emergency landings of the aircraft. In this paper, an algorithm is developed to design a ring-slot type brake parachute based on deployment speed and required dynamic characteristics. A computational model is developed using MATLAB to simulate the behaviour of the canopy o关键词: Brake parachute;Design and simulation;Light weight aircraft

摘要: The Payaswini-Chandragiri river system comprises two small tropical rivers originating in the Western Ghats (Patti Ghats reserve forest) of Peninsular India and contributes to an annual discharge of 4.40 km3/year into the Arabian sea. This work mainly focuses on the fluxes of total dissolved organic carbon (DOC) from these rivers into the Arabian Sea. Quantifying the amount of terrestrial carbon fluxes into the ocean is important in better understanding long-term climate change becaus关键词: Tropical river system;dissolved organic carbon;spatio-temporal variation;DOC flux;DOC yield;Arabian sea

摘要: Photoplethysmogram (PPG) sensing is a field of signal measurement that involves accurate sensor design and efficient signal processing. Sensing interfaces have matured due to use of sophisticated nano-meter technologies, that allow for high speed, and low error sampling. Thus, in order to improve the efficiency of PPG sensing, the signal processing unit must be tweaked. A wide variety of algorithms have been proposed by researchers that use different classification models for signal conditioning关键词: Blood pressure;PPG;sensing;ensemble;classifier

摘要: In a federal structure, India's determination to much-needed fiscal reforms has been widely applauded at its face value when she relinquished her previous complex and inefficient tax regime to embrace the long-awaited Goods and Services Tax (GST). It has been a significant economic move post-independence and requires validation of facts after its introduction. The present study aims to present a general macroeconomic analysis of the extent to which the adoption of GST has improved existing tax a关键词: GST;Indian economy;Indirect tax;Innovation implementation;Public policy;SAP–LAP analysis

摘要: The rare-earth magnetism in the intermetallic compound Yb0.5Ce0.5Ni5 was studied using X-ray diffraction, magnetization, heat capacity, and electrical resistivity measurements. The effect of spin fluctuations (SF) was observed in M(T) at ~40 K. The measurement of thermal and transport properties supported the results obtained from magnetic measurements. Collected experimental data showed that Yb/Ce substitution shifts the maximum temperature for spin fluctuations to a lower temperature compared 关键词: rare-earth elements;magnetic properties;spin fluctuations

摘要: Nowadays, voluminous unstructured data is steaming on the Web/social media. It is not easy for individuals to find relevant information quickly from such a vast unstructured corpus. Text summarizing is the process of retrieving relevant information in brief without changing the fundamental meaning of information. Manual text summarization takes much time, cost and effort to summarise. Researchers worked on different machine learning approaches to summarise the text in the past but still lagging 关键词: Extractive text summarization;Deep Learning;Abstractive text summarization;Reinforced learning

摘要: Expansion of CGG trinucleotide repeats in 5′ untranslated region of the FMR1 gene is the causative mutation of neurological diseases such as fragile X syndrome (FXS), fragile X-associated tremor/ataxia syndrome (FXTAS), and ovarian disorder such as fragile X-associated primary ovarian insufficiency (FXPOI). CGG repeats containing FMR1 transcripts form the toxic ribonuclear aggregates, abrupt pre-mRNA splicing, and cause repeat-associated non-AUG translation, leading to the disease symptoms.

摘要: Non-Orthogonal Multiple Access (NOMA) is an ideal choice for 5G waveforms due to their characteristics such as high data rate, massive device connectivity, high spectral access, and effective frequency selective fading. Thus, it permits gigantic connectivity. The spectrum overlaps with NOMA, which consents several operators to segment the spectrum at the same frequency. These features make NOMA more suitable for use beyond 5G. Peak to Average Power (PAPR) is a major problem in Multi-Carrier Tech关键词: VM-PTS; NOMA; PAPR; 5G

摘要: A single renewable source is insufficient for providing a reliable and continuous power supply. The multi-input DC to DC converter (MIDC) provides for the hybridization of different energy sources with a single output. Various grid voltages exist and different applications require different DC voltages. If the MIDC provides multiple outputs, it becomes a multi-input multi-output (MIMO) converter. In this paper, a triple input triple output (TITO) DC–DC buck-boost converter is proposed for voltag关键词: DC–DC converter;Multi input multi output (MIMO) converter;One cycle control (OCC);Power management

摘要: Potable water is an essential component of concrete as it is actively involved in the hydration and setting of concrete. Due to overpopulation, urbanization, and lack of proper water resource management, the available freshwater does not meet the demand resulting in water scarcity. Globally half of the world’s population is expected to suffer from a lack of access to proper water by 2025. The cumulative water consumption for concrete production was 16.6 km3 annually.
