STUDY OF CONDENSER AND ITS DIFFERENT TYPES
This study examines different types of condensers used in refrigerants. It discusses air cooled and water cooled condensers. Air cooled condensers can use natural or forced convection, while water cooled condensers include tube-in-tube, shell-and-coil, and shell-and-tube designs. The study tests different materials for condensers, finding that copper has the highest thermal conductivity and best heat transfer, followed by aluminum and steel. The objective is to select the best material for a condenser by considering factors like thermal conductivity and heat transfer performance.
Tema basics of construction 07.10
Shell and tube heat exchangers are widely used to transfer heat in industrial processes. They have tubes that carry one fluid inside the shell, which carries another fluid on the outside of the tubes. This allows for large heat transfer in a compact design. There are two main types - smaller designs under 12" in diameter used for applications like cooling liquids and larger designs over 10" diameter often built to standards to allow interchangeability. Key components include tubes attached to tube sheets in the shell, with ports for the inlet and outlet fluids to enter and exit separately.

TECNOLOGIE OPEN SOURCE PER INDUSTRIA 4.0 - Code_Aster & Injection Molding
Nello stampaggio ad iniezione dei polimeri (injection molding) la termica dello stampo riveste un ruolo fondamentale sulla qualità del pezzo prodotto. Lo stampo, oltre a conferire la forma, è progettato con un circuito di condizionamento utile a smaltire omogeneamente il calore necessario a far solidificare il pezzo mantenendo allo stesso tempo una temperatura superficiale sufficientemente alta da permettere lo scorrimento del polimero nella cavità. Durante l’avvio produzione lo stampo passa da temperatura ambiente alle condizioni di regime attraverso un transitorio che dura un certo numero di cicli di stampaggio non noto a priori, normalmente i pezzi prodotti in questa fase vengono scartati in quanto non conformi. In questo lavoro Code_Aster è stato utilizzato per ottimizzare un avvio produzione simulando l’evoluzione termica derivante da una serie di cicli di stampaggio a partire da una condizione di avvio definita. Lo script di simulazione è stato inoltre progettato per interfacciare Code_Aster con un file xml contenente i parametri con cui l’operatore può facilmente modificare le condizioni del ciclo produttivo (iniezione, raffreddamento ed estrazione), i parametri del circuito di condizionamento e tutte le condizioni geometriche al contorno. Il responsabile produzione, utilizzando questo script Code_Aster, sarà così in grado di individuare preventivamente i settaggi macchina migliori per ridurre i cicli necessari al raggiungimento della condizione stazionaria, risparmiando tempo e risorse. Lo sviluppo dello script prevederà l’accoppiamento indiretto delle superfici di condizionamento con una simulazione CFD eseguita su openFoam al fine di migliorare l’accuratezza dei risultati.

Iron and Steel Technology Roadmap - Towards more sustainable steelmaking.pdf
Iron and Steel Technology towards Sustainable Steelmaking
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
