Extended- reach drilling engineering suffers from high non-production costs due to stuck incidents of drill strings. Therefore, determining the depth at which stuck occurs is important in this process. Measurement techniques are used to identify stuck locations, but these processes are time-consuming. and costly. Due to current operational limitations, calculation methods are still used to estimate stuck point depth. The analytical techniques used nowadays are only applied to vertical wells and do not take into account the inclination and azimuth changes as well as friction factors........

This research explores the application of autoencoders in cryptography for text encryption and decryption, aiming to enhance throughput and security. We propose a system that leverages a neural network-based autoencoder to convert plaintext into a compact latent representation, which is then encrypted for secure storage or transmission. The system employs a custom password-based protection mechanism to ensure decryption only by authorized users. Key performance metrics, including encryption and decryption time and throughput (measured in KB/ms), are evaluated to assess the system's efficiency........

Since the medical images frequently contain sensitive patient data, the growing digitization of healthcare has raised serious concerns about medical image security. In order to provide strong protection, this study suggests a revolutionary two-stage encryption method for medical photos that combines the Lorenz Algorithm with an Improved Logistic Chaotic Map. Steganography is also used to embed the encrypted image in a cover file, which hides the data and adds an additional layer of security.The technology fixes vulnerabilities that arise when medical images are sent and stored across unprotected networks or cloud services. Preprocessing methods guarantee effective encryption without sacrificing image quality. This strategy seeks to adhere to stringent patient data privacy laws, enhance health informatics security, and protect medical data. The suggested approach shows great promise for effectively protecting huge, high-resolution medical photographs, which qualifies it for use in practical healthcare settings.

The project theme is to develop a "DESIGN OF HEXAGONAL MULTI INPUT MULTI OUTPUT ANTENNA FOR ULTRA-WIDE BAND APPLICATIONS." MIMO technology is widely used in wireless communication systems due to its ability to enhance data rates and system reliability. In this project, we design a hexagonal multi-input multi-output (MIMO) antenna for ultra-wideband (UWB) applications. The proposed antenna structure ensures compactness while maintaining excellent impedance matching and stable radiation characteristics. The antenna supports high-speed wireless communication by providing a broad impedance bandwidth and consistent gain performance. The design and simulation results validate its efficiency, making it a suitable choice for modern wireless communication applications.
