Pineapple is a tropical fruit that is highly relished for its unique aroma and sweet taste. In contrast to other tropical fruits, pineapples typically feature medium-sized fruits with yellow flesh. Based on the physical properties of pineapple fruit variety MD2 such as dimensions, geometric mean diameter (Dg), arithmetic mean diameter arithmetic mean diameter (Da), surface area, volume, sphericity, aspect ratio, and projected area and the best-fit mass models have been determined. From the result obtained, the physical properties such as length, thickness, width, Dg, Da and circumference were found to be 217.8mm, 132.7mm, 132.9mm, 156.5mm, 161.2mm, 394.3mm respectively. Meanwhile for the aspect ratio, mass, volume surface area, sphericity and projected area perpendicular to dimension namely PAL, PAT, AND PAW were found to be 0.61, 1730.4g, 1420 cm3, 77107.4 mm2, 0.72, 22746.0 mm2, 13942.9 mm2, and 16866.3 mm2 respectively. For all physical properties except volume, the best fit mass model to predict mass of pineapple fruits was the quadratic model. Additionally, the findings demonstrated that, in comparison to other attributes, the mass model based on actual volume was more appropriate, with the highest determination coefficient (R2) for Quadratic and S-curve model. For developing and optimizing machinery for handling, maintenance, distribution, and storage, the mass model of pineapple fruits according to the actual volume in the outcomes is relatively important.

The significance of macroeconomic policy changes on ETF markets and financial markets cannot be disre-garded. This study endeavors to predict the future trend of these markets by incorporating a group of selected economic indicators sourced from various ETF markets and utilizing probabilistic autoregressive recurrent net-works (DeepAR). The choice of economic indicators was made based on the advice of a domain expert and the results of correlation estimation. These indicators were then divided into two categories: "US" indicators, which depict the impact of US policies such as the federal reserve fund rate and quantitative easing on the global markets, and "region-specific" indicators. The findings of the study indicate that the inclusion of "US" indicators enhances the prediction accuracy and that the DeepAR model outperforms the LSTM and GRU models. Fur-thermore, a web platform has been developed to apply the DeepAR models, which enables the user to predict the trend of an ETF ticker for the next 15 time-steps using the most recent data. The platform also possesses the capability to automatically generate fresh datasets from corresponding RESTful API sources in case the current data becomes outdated.

Speech is the basis of human-computer interfaces, smart house, IoT and control systems. Implementing a real time voice control system through speech commands recognition in different environments requires simple algorithms and special purpose systems. The article analyzes the existing speech commands recognition algorithms in embedded systems. A simple and efficient algorithm for voice control systems through limited speech commands has been proposed.

Respiratory diseases pose a major public health concern in many cities worldwide, and the city of Batna is no exception. Over the past five years (2018-2023), respiratory diseases have likely been one of the primary health concerns for healthcare professionals and public health authorities in this region. This article provides an in-depth evaluation of the spread of these diseases in the city of Batna, focusing on trends, risk factors, high-risk seasons, and implications for public health and presents a comprehensive evaluation of the spread of respiratory diseases in the city of Batna over a five-year period, from 2018 to 2023. Respiratory diseases constitute a major public health issue in this urban region and have been a significant concern for healthcare professionals and authorities. The study methodology relies on extensive data collection from hospitals, health centers, and clinics in Batna, taking into account demographic, climatic, and environmental factors. Trend analysis reveals seasonal variations and significant increases in the spread of respiratory diseases. Risk factors such as air pollution, outbreaks of respiratory viruses, smoking, and housing conditions are also examined. The findings provide recommendations to improve prevention, early diagnosis, and management of respiratory diseases, with the goal of reducing their impact on the population of Batna. This study offers future perspectives to strengthen public health strategies and deepen the understanding of the mechanisms of disease propagation. By highlighting these crucial aspects, this article contributes to raising awareness among policymakers and healthcare professionals about the importance of combating respiratory diseases in this specific region.

The calculation of frame structures requires special attention when modeling the beam-column connection. Often the joint is assumed to be rigid, but this does not correspond to the real behavior of the beam-column connection, as well as the real response of frame structures. The leading countries in seismic research (USA, New Zealand, Japan) have uniform procedures introduced in their seismic codes for studying the moment resisting frame. However, regarding the determination of the shear force in the beam-column connection, there is still a discrepancy in how it is determined. In the present work, a mathematical model is proposed for the analytical determination of the shear force. The emerging large deformations in the beam, which could be realized during earthquake, have been taken into account. The material is elastic. The obtained values are compared with results determined by mathematical procedures proposed in other literature sources.
