Abrasive jet machining (AJM) uses a high-pressure stream of abrasive particles carried by gas or air to remove material from a workpiece. The abrasive particles are forced through a small nozzle at high velocity to impact the work surface. This allows for drilling intricate holes and cutting hard, brittle materials like ceramics more precisely than sand blasting. The process parameters like material removal rate, surface finish, and nozzle wear depend on factors such as abrasive size and flow rate, gas pressure and velocity, and nozzle size and position. AJM is well-suited for deburring and precision machining of small parts made of difficult materials like ceramics, glass, and superalloys

“We don’t want to limit designer creativity too soon by bringing tech into the process.”
“We don’t want to waste developer time at the beginning when there’s nothing fully defined yet.”
“If we design a detailed enough style guide, development should be able to implement without retaining a designer through implementation.”
How do you find the right balance of involvement without breaking the budget - and make the most of the skills that each team member can bring to the table?
In this presentation, Carolyn Chandler (Experience Designer and instructor) and Don Bora (Developer and iconic tech mentor) will take you on a journey through the main stages of a project from both sides of the divide.

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%.

A review on techniques and modelling methodologies used for checking electrom...
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Embedded machine learning-based road conditions and driving behavior monitoring
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.

Abrasive Jet Machining (AJM)
- 1. ABRASIVE JET MACHINING (AJM) Presented By – Mohammed Tayeeb
- 2. Introduction A stream of abrasive grains (Al2O3 or SiC) is carried by high pressure gas or air (compressed). Impinges on the work surface at very high velocity through a nozzle of 0.3 to 0.5 mm diameter. Sand Blasting (SB) - a similar process The major differences between are SB and AJM (i) smaller diameter abrasives (ii) a more finely controlled delivery system Material removal – by mechanical abrasion action of the high velocity abrasive particles. Best suited for hole drilling in superhard materials.
- 4. Process Parameters MRR, machining accuracy, surface roughness and nozzle wear are influenced by Size and distance of the nozzle. Composition, strength, size, and shape of abrasives Flow rate Composition, pressure, and velocity of the carrier gas. MRR is mainly dependent on the flow rate and size of abrasives.
- 5. Applications Drilling holes, cutting slots, cleaning hard surfaces, deburring, polishing,and radiusing. Deburring of cross holes, slots, and threads in small precision parts that require a burr-free finish, such as hydraulic valves, aircraft fuel systems, and medical appliances. Machining intricate shapes or holes in sensitive, brittle, thin, or difficult-to-machine materials. Insulation stripping and wire cleaning without affecting the conductor.
- 6. Advantages Because AJM is a cool machining process, it is best suited for machining brittle and heat-sensitive materials like glass, quartz, sapphire, and ceramics. The process is used for machining superalloys and refractory materials. It is not reactive with any workpiece material. No tool changes are required. Disadvantages The tapering effect may occurs especially when drilling in metals. The removal rate is slow The abrasive get impended on the work surafce. Soft metals can’t be machined by the process.
