This document proposes an RFID-based ticketing system for the public transport system in Dhaka, Bangladesh to address issues with the current paper-based system. The proposed system would use RFID tags on buses to track their arrival and departure at stops and RFID-enabled tickets carried by passengers. Passengers would provide their destination in the bus and fares would be automatically deducted from their tickets based on distance traveled. This system aims to standardize fares, reduce confusion and corruption, and provide real-time arrival/departure information to passengers.

Game playing is a common technique used in artificial intelligence that involves pitting computer algorithms against human experts or other players. It has been a focus since the early days of AI and provides a visible test of computer skills. Game playing is used in computer and video games to simulate intelligent behavior by non-player characters through techniques from fields like computer science, graphics, and animation. The goals of AI in games are to provide both a reasonable challenge and natural behavior without cheating, through means such as vehicles that drive faster or characters with more health. Games can involve perfect or imperfect information for players.
Audio spot lighting is a new technology that uses ultrasonic frequencies to create narrow beams of focused sound in a similar way that light can be focused into a beam. It exploits the non-linearity of air to generate audible sound from ultrasonic waves. An array of transducers emit ultrasonic signals that distort in a predictable way as they pass through air, generating a focused beam of audible sound that only those within the beam can hear without disturbing others nearby. This technology allows sound to be targeted to specific listeners without the dispersion of omnidirectional speakers. It has applications in areas like retail stores, museums, and public announcements.
Computer vision - images and image filtering Wael Badawy
This document provides an overview of image filtering and linear filtering techniques. It begins with definitions of what an image is from a digital perspective - as a grid of intensity values. It then discusses how image transformations like filtering work by applying operators to modify pixel values based on neighboring areas. Specifically, it focuses on linear filtering using convolution or cross-correlation to replace pixel values with a weighted sum of surrounding pixels according to a kernel or filter. Examples of common linear filters are presented like mean, Gaussian, and sharpening filters. It also discusses how filtering can be used for tasks like noise reduction, blurring and sharpening.
Haptics is a technology that adds the sense of touch to interactions with virtual objects by connecting user movements and actions to corresponding computer-generated feedback such as forces, vibrations, and motions. This allows virtual objects to seem real and tangible to the user. Haptics links the brain's sensing of body position and movement through sensory nerves to provide an immersive experience when interacting with virtual environments and simulated objects.
Surface computing allows natural interaction with digital information through touch, gestures, and physical objects on a horizontal display. The Microsoft Surface uses infrared cameras beneath the screen to sense touch input and recognize objects placed on it. It can process multiple touches simultaneously and is used in retail stores, hotels, and restaurants for applications like viewing menus, sharing content, and making purchases. While the technology is promising, issues like the high cost may limit mainstream consumer adoption for now.
The x86 instruction set architecture began with Intel's 16-bit processors in the 1980s and has since evolved through numerous extensions. It supports multiple execution modes including 16-bit real mode, 32-bit protected mode, and 64-bit long mode. The instruction format includes optional prefixes, opcode bytes, addressing fields, and immediate data. General purpose registers are used for operands along with memory addressing modes. Subsequent x86 architectures, such as AMD64, expanded register sizes and added new instructions while maintaining backwards compatibility.
