Accurate Satellite Operation Predictions Using Attention-BiLSTM Model with Telemetry Correlation

In satellite health management, anomalies are mostly resolved after an event and are rarely predicted in advance. Thus, trend prediction is critical for avoiding satellite faults, which may affect the accuracy and quality of satellite data and even greatly impact safety. However, it is difficult to predict satellite operation using a simple model because satellite systems are complex and telemetry data are copious, coupled, and intermittent. Therefore, this study proposes a model that combines an attention mechanism and bidirectional long short-term memory (attention-BiLSTM) with telemetry correlation to predict satellite behaviour. First, a high-dimensional K-nearest neighbour mutual information method is used to select the related telemetry variables from multiple variables of satellite telemetry data. Next, we propose a new BiLSTM model with an attention mechanism for telemetry prediction. The dataset used in this study was generated and transmitted from the FY3E meteorological satellite power system. The proposed method was compared with other methods using the same dataset used in the experiment to verify its superiority. The results confirmed that the proposed method outperformed the other methods owing to its prediction precision and superior accuracy, indicating its potential for application in intelligent satellite health management systems.

A low-cost spectroscopic nutrient management system for Microscale Smart Hydroponic system.

Hydroponics offers a promising approach to help alleviate pressure on food security for urban residents. It requires minimal space and uses less resources, but management can be complex. Microscale Smart Hydroponics (MSH) systems leverage IoT systems to simplify hydroponics management for home users. Previous work in nutrient management has produced systems that use expensive sensing methods or utilized lower cost methods at the expense of accuracy. This study presents a novel inexpensive nutrient management system for MSH applications that utilises a novel waterproofed, IoT spectroscopy sensor (AS7265x) in a transflective application. The sensor is submerged in a hydroponic solution to monitor the nutrients and MSH system predicts the of nutrients in the hydroponic solution and recommends an adjustment quantity in mL. A three-phase model building process was carried out resulting in significant MLR models for predicting the mL, with an R2 of 0.997. An experiment evaluated the system's performance using the trained models with a 30-day grow of lettuce in a real-world setting, comparing the results of the management system to a control group. The sensor system successfully adjusted and maintained nutrient levels, resulting in plant growth that outperformed the control group. The results of the models in actual deployment showed a strong, significant correlation of 0.77 with the traditional method of measuring the electrical conductivity of nutrients. This novel nutrient management system has the potential to transform the way nutrients are monitored in hydroponics. By simplifying nutrient management, this system can encourage the adoption of hydroponics, contributing to food security and environmental sustainability.

Short-Term Response of Soil Organic Carbon Indices to Different Farming Strategies and Crop Rotation Systems in a Semiarid Warm Region

Several indices can be used to assess the impact of short-term conservation agriculture strategies on improving soil organic carbon (SOC). To find out how the SOC pools and the carbon lability influence the carbon management index (CMI) in response to different agricultural practices in a warm semiarid region, the carbon lability index (LI) and the carbon pool index (CPI) were measured under the interactive effect of different fertilizer applications and crop residue management (hereafter referred to as “farming strategies”) in combination with four crop rotation systems in Ahvaz, Khuzestan, Iran, over four growing seasons from 2018 to 2020. The farming strategies were as follows: (1) using the standard rate of inorganic fertilizer used in the region and removing crop residues from the soil (SIF_no-CR); (2) applying the standard rate of organic fertilizers used in the region and returning 30% of crop residues to the soil (SOF_30% CR); and (3) integrating the use of inorganic and organic fertilizers and returning 15% of crop residues to the soil (IOF_15% CR). The crop rotation systems were fallow-wheat (F-W), corn-wheat (C-W), sesame-wheat (S-W), and mung bean-wheat (B-W). No statistically significant difference was observed between the different farming strategies and rotation systems with respect to LI after two years of the experiment. The highest (1.26) and lowest (1.06) CPIs were observed for SOF_30% CR and SIF_no-CR, respectively. The magnitude of the CMI values followed the order SOF_30% CR (121) > IOF_15% CR (107) ≥ SIF_no-CR (106). B-W and F-W had the highest and lowest CPI with values of 1.29 and 1.01, respectively. No statistically significant difference was found for the different crop rotation systems. Given the low impact of the common farming practices in the region, e.g., SIF_no-CR and F-W, on CPI and CMI at 24 months, our results showed that farming strategies with manure application and crop residue management and summer wheat-based rotation systems appear to be more appropriate farming strategies to improve CMI in arable land.

Influence of feed intake management system on cattle intake and growth performance

Variation in feed intake systems and subsequent bunk management between research settings and the beef industry has increased over the last decade. Despite the need for both feed management application systems in the beef industry, a comparison of feed intake, cattle intake behavior, and growth performance between cattle fed in an open bunk system compared to an individual intake system has not been conducted. Therefore, the objective of this study was to evaluate feed intake, growth performance, and carcass characteristics of steers fed in an individual feed intake bunk system (FIMS) compared to a traditional, open bunk system. One hundred twelve crossbred yearling steers (n = 28 hd/pen) were randomly assigned to one of two treatment groups: 1) fed in individual feed intake systems (FIMS) or 2) fed in traditional open bunk system (OPEN) with 2 pens per treatment. Steers fed in FIMS were managed to allow for ad libitum feed access while steers fed in concrete open bunks were managed using the South Dakota State University 4-point bunk scoring system, targeting slick bunks or bunk score of 0 three to five days per week with the remainder of the days being bunk scores of ½ to 1. Over the 103-day feeding period, no difference in body weight or growth performance were observed between the two treatment groups with a tendency for ribeye area to be smaller in steers fed in FIMS. Results of this study demonstrated minimal differences performance and carcass characteristics of steers fed in an open bunk system in comparison to an individual intake bunk system. However, additional research is needed to determine the impact of bunk feeding system on individual steer social behavior to account for variation within pen.

Enhancing Performance Management Systems in a challenging environment

Amidst the backdrop of military conflicts, climate change, pandemics, and social disparities, it is clear that firms must acquire the necessary skills to effectively learn, respond promptly, and mitigate these global occurrences. Increased invest-ment in the deployment of robust and efficient performance management sys-tems is necessary to effectively lead firms in implementing their corporate strategy. Performance measurement systems encompass many processes, methods, and tools that are designed to quantitatively assess critical factors in order to facilitate the execution of a strategy. Moreover, these systems may serve as catalysts to promote debates and conversations, leading to the identification of improvement activities for corporate goals and performance. As a result, firms can achieve more rational growth. Moreover, when used and adjusted correctly, performance as-sessment systems enable firms to adapt and progress in accordance with the eco-nomic and social environment, as well as technological advancements, thus facing challenging contexts. Indeed, in performance measurement systems, it is crucial to ensure that the pa-rameters and measurement methods are appropriately adjusted. This is necessary to avoid a situation where the company's strategic goals, such as digitalization or sustainability, are measured in an unsuitable manner, delayed, and without align-ment with the formulated strategy or necessary adaptations. The volatility caused by external variables, such as emerging technology, envi-ronmental issues, crises, and organizational restructuring, influences and drives companies to implement and increase the utilization of performance measure-ment systems, which must be custom-designed to be aligned with the company's requirements. Indeed, the consensus in the research is that there is no universally applicable performance management system. Instead, its design is contingent up-on contextual factors such as the environment, technology, strategy, and culture.

ENERGY MANAGEMENT: NEW PRIORITIES OF THE 21ST CENTURY

The development of management methodology and the concept of energy management in modern conditions of transforming the energy sector by the requirements of the carbon-free economy are considered. New qualitative features and new areas of application of energy management and energy management systems (EMS) in the implementation of the energy transition and implementation of the Smart Grid concept have been revealed. It has been established that modern energy management is a proactive, organized, and systematic coordination of the purchase, transformation, distribution, and use of energy to meet requirements, taking into account environmental and economic goals. In contrast to the formation of the EMS according to the ISO 50000 series of standards, today the construction of the EMS is becoming more relevant, which provides systemic (complex) optimization of the parameters, structure, and modes of various technical objects according to a set of technical, economic and environmental criteria. It is shown that EMS is much more than a simple technical solution for monitoring the parameters and state of energy systems. With comprehensive forecasts of energy demand and supply, this system takes energy management to a completely new level, allowing operators of facilities (enterprises, buildings, and smart networks and systems) to determine the strategic direction of energy management, implement it, and achieve both energy efficiency and energy availability and environmental (social) acceptability. The components of EMS for Smart Grid are characterized, in particular: monitoring (actual energy production, actual energy demand, state of charge of energy storage, price uncertainty); forecast (energy production, energy demand, mobile data storage, uncertainty); power quality management (loss minimization, power quality indicators, and reliability/comfort); planning/dispatch/cost (operating costs, reduction of GHG emissions, profit maximization). It is proposed that a promising direction is to consider the SEM as a system of information and communication technologies, which at the system level is combined with power energy processes used by operators of electric power systems and networks to monitor, control, and optimize the productivity of production, transmission, and consumption of energy resources in systems of various hierarchical levels. level (as UES of Ukraine, regional and local systems, on specific energy facilities or individual energy technologies, etc.). Based on the analysis of prospective areas of application of EMS at energy sector facilities, modern areas of scientific and technical research in the construction of energy management systems for energy, electric power, and electrotechnical systems, which are practical to carry out in Ukraine, have been determined.

Dielectric flow- and tab-based battery thermal management system for EV high performance application

From the perspectives of security, durability, and proper operation, effective temperature control via thermal management systems (TMSs) on lithium-ion batteries is crucial for electric vehicle use. In this regard, a novel TMS based on dielectric flow and tab cooling was presented in this paper. A functional prototype of the system was developed and experimentally tested for performance analysis. A thermal model was built on computational fluid dynamics software, and a comparative analysis of the initial and an optimised geometry of the prototype was carried on after validation. Results demonstrate the adequate response of the system. Thermally speaking, temperature decrease was noticed during operation, and the internal and among-cells thermal gradient was preserved into the recommended span. Besides, the used dielectric fluid assisted with a low auxiliary consumption due to its particular viscosity. With the new geometry, the dielectric flow duct volume was reduced by 79.8%, and the system particularities were enhanced due to heat dissipation improvement: operating temperatures were even lower in every scenario examined. The temperature difference among cells was reduced by 15%. Thermal dispersion within the cells was still below the limit, despite being increased. Moreover, the necessary pumping energy consumption was below 0.004% of the exchanged battery module’s energy, demonstrating the TMS efficiency. Thus, the application potential of the dielectric tab cooling-based system for electric vehicles was highlighted.

A novel nonlinearity-aware adaptive observer for estimating surface concentration and state of charge of lithium-ion batteries

Physically based electrochemical models can provide internal state information of batteries, exhibiting significant potential for application in battery management systems across various lithium-ion battery products. However, the complex structure and limited observability of electrochemical models make their integration into battery management systems challenging. In this paper, a novel nonlinearity-aware adaptive (i.e., NAA) observer based on a simplified electrochemical model is proposed for estimating the electrode surface concentration and state of charge. The proposed NAA observer can identify the nonlinearity of the electrochemical model and switches to the most suitable observer structure automatically. Experimental tests on a cylindrical battery were conducted to observe the performance of the observer. The results demonstrate rapid convergence and high accuracy of all estimated states under an initial state error of 20%. Furthermore, to thoroughly validate the performance of the proposed observer, a comparison was made with an interconnected sliding mode observer based on electrochemical models, considering initial state uncertainty, sensor noise, and computation time.

Multi-scenario PM2.5 distribution and dynamic exposure assessment of university community residents: Development and application of intelligent health risk management system integrated low-cost sensors

Exposure scenario and receptor behavior significantly affect PM2.5 exposure quantity of persons and resident groups, which in turn influenced indoor or outdoor air quality & health management. An Internet of Things (IoT) system, EnvironMax+, was developed to accurately and conveniently assess residential dynamic PM2.5 exposure state. A university community “QC”, as the application area, was divided into four exposure scenarios and five groups of residents. Low-cost mobile sensors and indoor/outdoor pollution migration (IOP) models jointly estimated multi-scenario real-time PM2.5 concentrations. Questionnaire was used to investigate residents' indoor activity characteristics. Mobile application (app) “Air health management (AHM)” could automatic collect residents' activity trajectory. At last, multi-scenario daily exposure concentrations of each residents-group were obtained. The results showed that residential exposure scenario was the most important one, where residents spend about 60 % of their daily time. Closing window was the most significant behavior affecting indoor contamination. The annual average PM2.5 concentration in the studied scenarios: residential scenario (RS) < public scenario (PS) < outdoor scenario (OS) < catering scenario (CS). Except for CS, the outdoor PM2.5 in other scenarios was higher than indoor by 5–10 μg/m3. The multi-scenario population weighted annual average exposure concentration was 37.1 μg/m3, which was 78 % of the annual average outdoor concentration. The exposure concentration of 5 groups: cooks > outdoor workers > indoor workers > students > the elderly, related to their daily activity time proportion in different exposure scenario.
