Aerial roof measurements are really pretty basic for a technology that may be so beneficial to your business. Pictures of houses and commercial properties are captured from the above by planes or drones. A report with accurate measurements of a roof's area, length, and pitch is prepared from these photographs. The ridges, hips, valleys, rakes, eaves, flashing, and step flashing of a roof are frequently measured.
3D Printing
This document provides an overview of 3D printing, including what it is, how the process works, and some applications. 3D printing is a process that uses additive manufacturing to make 3D objects by laying down successive layers of material based on a digital model. It can be done through various methods like extrusion deposition of plastics, binding of granular materials, lamination of sheets, or photopolymerization of liquid polymers using UV light. 3D printing allows for quick prototyping of parts and can be used to recreate artifacts for archaeology, reconstruct bones for forensics or pathology, and produce open source scientific equipment and more.

Application of Mathematical Modelling to Virtual Manufacturing
To analyze and modify manufacturing process in virtual environments, mathematical modelling can be used. Effects and behavior of the system are simulated by mathematical concepts in order to be analyzed and modified. So, different parameters of the process can be analyzed in order to be optimized. Thus, efficiency of part production can be increased by applying optimization methods to the simulated manufacturing process in virtual environments. Modification can also be presented to the simulated system in virtual environments by analyzing and decreasing errors of manufacturing process. Therefore, accuracy of produced parts can be increased in order to improve efficiency of part production.

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%.
