Two Dimensional Window Design
Windowing is a process where an index limited sequence has its maximum energy concentrated in a finite frequency interval. This can be extended to an N-dimension where the N-D window has the limited support and maximum concentration of energy in a separable or non-separable N-D passband. The design of an N-dimensional window particularly a 2-D window finds applications in various fields such as spectral estimation of multidimensional signals, design of circularly symmetric and quadrantally symmetric non-recursive 2D filters, design of optimal convolution functions, image enhancement so as to reduce the effects of data-dependent processing artifacts, optical apodization and antenna array design.

Brain Tumor Detection Using Federated Learning
Brain tumor segmentation in medical imaging is a critical task for diagnosis and treatment while preserving patient data privacy and security. Traditional centralized approaches often encounter obstacles in data sharing due to privacy regulations and security concerns, hindering the development of advanced AI-based medical imaging applications.

Music Transcription
Music transcription is the process of transforming recorded sound of musical performances into symbolic representations such as sheet music or MIDI files. At the most fundamental level, frame-level transcription involves analyzing very short frames of audio and identifying basic sound characteristics of music such as pitch and timbre. In the next step, note-level transcription takes the information gathered from frame-level analysis and assembles it into individual musical notes. This level of transcription can identify the pitch, duration, and timing of each note in the piece of audio. The stream-level transcription looks beyond individual notes to capture the larger musical phrases. This involves recognizing patterns in the sequence of notes, identifying chord progressions, and determining the overall structure of the music like verses and choruses in a song. The highest level of transcription involves creating a formal written representation of the music notation. This includes not only the individual notes and their timing but also various musical symbols such as dynamics, articulations, time signatures, key signatures, and more.

LiFi- and WiFi-Based Communication P2P Networks
Peer-to-Peer (P2P) networks have emerged as potential solutions to issues that cause inefficient download times in networks because they can use the resources in the entire network, allowing nodes to act both as servers and clients simultaneously.

Livescribe
The Livescribe paper-based computing platform consists of a digital pen, digital paper, software applications, and developer tools. Central to the Livescribe platform is the smartpen, a ballpoint pen with an embedded computer and digital audio recorder. When used with Anoto digital paper, it records what it writes for later uploading to a computer, and synchronizes those notes with any audio it has recorded. This allows users to replay portions of a recording by tapping on the notes they were taking at the time the recording was made. It is also possible to select which portion of a recording to replay by clicking on the relevant portion of a page on-screen, once it has been synced to the Livescribe Desktop software. Jim Marggraff, inventor of the LeapFrog FLY Pentop computer and creator of the LeapPad Learning System, left Leapfrog in 2005 to form Livescribe. In November 2015, Livescribe announced its acquisition by Anoto for $15m.

Track Warrant
Track warrants are systematized permissions used on some railroad lines to authorize a train's use of the main line. Dispatchers issue these permissions to train crews instead of using signals. The crews receive track warrants by radio, phone, or electronic transmission from a dispatcher.

Energy Efficient Dynamic Symmetric Key in Smart Homes
Smart home security is paramount owing to the private and sensitive information exchanged between the smart devices and the remote users. In this entry, a symmetric key authentication procedures are presented for smart home networks. The proposed protocol leverages on cryptographic primitives such as one-way hashing and bit-wise exclusive-Or operations. Evaluation results show that it is efficient and more secure when compared with other state of the art approaches.

Truevision TGA
Truevision TGA, often referred to as TARGA, is a raster graphics file format created by Truevision Inc. (now part of Avid Technology). It was the native format of TARGA and VISTA boards, which were the first graphic cards for IBM-compatible PCs to support Highcolor/truecolor display. This family of graphic cards was intended for professional computer image synthesis and video editing with PCs; for this reason, usual resolutions of TGA image files match those of the NTSC and PAL video formats. TARGA is an acronym for Truevision Advanced Raster Graphics Adapter; TGA is an initialism for Truevision Graphics Adapter. TGA files commonly have the extension ".tga" on PC DOS/Windows systems and macOS (older Macintosh systems use the "TPIC" type code). The format can store image data with 8, 15, 16, 24, or 32 bits of precision per pixel – the maximum 24 bits of RGB and an extra 8-bit alpha channel. Color data can be color-mapped, or in direct color or truecolor format. Image data may be stored raw, or optionally, a lossless RLE compression similar to PackBits can be employed. This type of compression performs poorly for typical photographic images, but works acceptably well for simpler images, such as icons, cartoons and line drawings.
