Authors: Bandlamudi Alex 
Published: January 2025

Abstract

Accurately forecasting residential energy consumption is essential for efficient energy management and optimization. This study aims to develop predictive models to forecast household energy consumption for the next 15 days (multi-step ahead forecasting) of a given month, based on the previous 15 days of data. Using minute-level data collected over 15 days from a residential setup with an ESP32 microcontroller and a PZEM-004T energy monitoring module, this study examines the capabilities of ARIMA and LSTM models in predicting future energy consumption. The data underwent extensive preprocessing, including normalization, differencing, and stationarity tests, to ensure suitability for modeling. The ARIMA model, configured with an order of (1, 2, 15), and the LSTM model, featuring four LSTM layers with varying dropout rates, were evaluated for their forecasting accuracy. The ARIMA model achieved a Root Mean Squared Error (RMSE) of 0.0217 and a Mean Squared Error (MSE) of 0.0009. Conversely, the LSTM model demonstrated superior performance with an RMSE of 0.0196, a test loss of 0.000851, and a lower Mean Absolute Error (MAE) of 0.015, compared to the ARIMA model's MAE of 0.025. Additionally, the LSTM model achieved a more favorable Mean Absolute Percentage Error (MAPE) of 3.0%. These findings highlight the effectiveness of LSTM models in capturing complex temporal patterns and improving forecasting accuracy compared to traditional ARIMA models. This research provides valuable insights into advanced energy forecasting methodologies, laying the groundwork for future work in residential energy optimization.\section*{\small Article Highlights}\begin{itemize}\item LSTM models outperform ARIMA in predicting household energy usage by capturing complex patterns.\item Minute-level data enhances the accuracy of short-term energy consumption forecasting.\item Real-time LSTM-based predictions could optimize energy management in smart homes.\end{itemize}

Abstract

Satellite nadir altimetry has been a powerful technique for understanding oceans and seas over the past few decades. However, over rivers and small inland water bodies, it produces erroneous observations, which can result in gaps or false measurements in water level time series. In this study, we aim to identify and correct anomalous measurements through reprocessing at the Level 1B (L1B) stage of the satellite altimetry processing chain. To this end, by analyzing various parameters related to the satellite’s altimeter, such as the AGC parameter, tracker range, and waveform shape features, we first detect anomalous waveforms that result in anomalous water level measurements. These waveform features include the number and location of peaks, noise level, kurtosis, center of gravity, and peakiness. Anomalous waveforms are identified through an analysis of the distribution of these features. While previous studies focused solely on L1B waveform to retrack multi-peak and noisy waveforms, we propose a robust strategy to regenerate anomalous waveforms within the L1B SAR processing chain by eliminating unwanted backscattered power. This approach incorporates the Fully-Focused Synthetic Aperture Radar technique into the L1B processing chain, dividing the illumination time into smaller stacks comprising multiple beam looks. Due to factors such as antenna side lobe gain, wide antenna footprints, and environmental unevenness, some beam looks may exhibit undesired patterns in generated waveform. Our proposed approach addresses this issue by comparing the power of individual stacks with an analytically derived reference waveform and assigning weights to each stack based on their similarity to the reference waveform abbreviated as segment-weighted Fully-Focused - Synthetic Aperture Radar (swFF-SAR). This reduces the impact of unwanted components in the backscattered final waveform and enables the regeneration of detected anomalous waveforms for inland waters. We applied the proposed method to Sentinel-3A, Sentinel-3B, and Sentinel-6MF data over 6 lakes and reservoirs of various sizes and validated the results against in-situ data. The validation demonstrates that the water height time series obtained from regenerated waveforms show significantly better agreement with in-situ data. Specifically, the accuracy of the water level time series, measured in terms of RMSE, improved by around 60% for the selected case studies.

Published: January 2025

Baby clam (Corbiculidae sp.) meat is served as a traditional dish in Vietnam, and the antioxidant activity of its protein extract has been discovered. This study evaluates baby clam meat protein hydrolysate's iron-binding capacity (IBC) and antidiabetic activity. Initially, an analysis of the basic chemical composition of the meat was conducted. Subsequently, Alcalase was employed for hydrolysis. The highest IBC and α-amylase inhibition activity were targets for obtaining the best hydrolysis condition, including the clam meat-to-water ratio, enzyme-to-substrate (E:S) ratio, and time. Under the best condition, the hydrolysates demonstrated the IBC of 1246.20 ± 44.00 µg Fe2+/g protein and α-amylase inhibition activity of 48.33 ± 1.44%, approaching three-quarters of the activity of ethylenediaminetetraacetic acid (EDTA) sodium salt and acarbose, respectively. These results served as preliminary data for the development of the protein hydrolysates as a natural iron chelator or α-amylase inhibitor, which could support the treatment of iron deficiency and diabetes.

Marxistas negros ou marxismos negros? Uma visão decolonial
Authors: Grosfoguel Ramon 
Published: January 2025

Neste artigo, identidicamos uma invisibilidade acerca da vasta produção do marxismo negro. Nosso objetivo com este trabalho é introduzir o tema e chamar a atenção para um problema sério: como o desconhecimento dessa tradição permite que ideias já trabalhadas e desenvolvidas por marxistas negros nos apareçam como novidades. Ocultar as origens negras das teorias críticas apenas serve para reproduzir o racismo epistêmico que estabelece o pensamento negro como inferior e o pensamento branco como superior.

Health fitness classes remain in demand in the process of physical education of female students of the Higher Education Institute of the Ministry of Health of Ukraine. In the context of the problematic situation regarding the lack of physical activity, health fitness classes provide an opportunity for female students to maintain an optimal level of physical health based on the differentiation of physical loads taking in to account the indicators of their motor age.
The purpose of the study is to determine and experimentally verify the effectiveness of fitness classes with female students of different motor ages based on the differentiation of physical exertion.
Research material and methods. To achieve the goal, the following research methods were used: analysis and generalization of data from scientific and methodical literature and the global network «Internet»; calculation methods for determining motor age; instrumental methods; pedagogical testing, methods of mathematical statistics. The contingent of the study is 40 female students of the I, II and III years medical faculties of Zaporizhzhia State Medical and Pharmaceutical University.
The results. An experimental program of health fitness classes was developed and tested, taking in to account a differentiated approach to the dosage of physical activity for female students of different motor ages. A rational combination of means of development of motor qualities was revealed: strength endurance – 15,9 %, dynamic strength – 12,9 %, speed-power endurance – 8,7 %, static endurance – 17,9 %, flexibility – 12,7 %, speed – 14,7 % and coordination abilities – 17,3 %. The study revealed a moderate negative correlation between indicators of motor age and the level of physical health (r = ‒0,7, at p < 0.01). Three levels of motor age have been identified based on physical health. The first level corresponds to optimal physical health: a motor age deviation from the chronological age of 0 to 11 years is characteristic of a "safe" motor age level, which includes female students with very high and high levels of physical health. Female students whose motor age is more than 12 ± 1 years older than their chronological age fall into the "borderline" zone and have an average (second) level of physical health. If the motor age exceeds the chronological age by 13 years or more, the body is in the "dangerous" zone—classified as the third level.
Conclusions. Taking in to account the motor age of female students during health fitness classes ensures an optimal level of motor activity and increases the level of physical fitness.
