This document discusses the Mconf project's Android client for BigBlueButton web conferencing. It provides an overview of Mconf and the authors, describes the Android client architecture and its main functionalities like public/private chat, voice interaction, video, and administrative controls. The client is compatible with Android 2.0+ and supports joining meetings via links or QR codes. Future plans include improving usability, stability, and integrating presentations. Contributions are welcomed through testing, feedback, translations, or code patches.
The document discusses scheduling in computing systems. It defines scheduling as the process by which the scheduler decides which ready process to run next. Scheduling is important in multi-programmed, multi-user, and batch systems to determine the order of execution of ready processes. The goals of different scheduling algorithms are discussed, including fairness, policy enforcement, balance/efficiency for general algorithms, and minimizing response time and meeting deadlines for interactive and real-time systems respectively. Popular scheduling techniques like round robin, priorities, and real-time scheduling are explained through examples.
This document discusses key questions to ask about electronic components, focusing on resistors and capacitors. For resistors, reasonable parameter values include resistances from 0.1Ω to 10MΩ, power ratings up to 1W, and tolerances of ±5% for carbon film and ±1% for metal film. Resistors have parasitic inductance and capacitance that affect behavior at high frequencies. Capacitors can store energy in an electric field according to the relationship between current, voltage, and capacitance.
This document provides an overview of design for quality principles from a lecture on electrical engineering design. It discusses total quality management and ISO quality standards that regulate design processes. Key points covered include: defining quality as satisfying customer needs at affordable cost; treating design as a special process requiring documentation and verification; establishing design input/output requirements and verification procedures; and planning design activities, resources, and reviews to ensure quality. The goal is to understand and control the design process through standards to minimize errors and better meet customer expectations.

This document discusses I/O device management and considerations. It introduces different categories of I/O devices and challenges in managing diverse devices with uniform interfaces. It covers I/O device properties like data rates, access methods, interrupts, and direct memory access. The document traces the evolution of I/O from simple controllers to advanced processors on I/O modules.
This document provides an overview of marketing tools that can be used during the electrical engineering design process. It discusses primary tools like surveys, focus groups, and interviews to understand customer needs and requirements. It also covers secondary market research tools to analyze industry trends, competitors, and potential customer demographics. The document emphasizes organizing customer feedback and prioritizing requirements to guide the design process. It also addresses estimating product price and sales volume.
This document discusses wideband frequency modulation (FM) and its properties. It begins by introducing the concept of FM and defining terms like modulation index and frequency deviation. It then shows that the FM signal can be expressed as a complex Fourier series involving Bessel functions. The spectrum of the FM signal is derived and shown to consist of sidebands spaced at multiples of the modulating frequency away from the carrier frequency. For small modulation indices, the spectrum reduces to the carrier and first sidebands, corresponding to narrowband FM.

This document provides an overview of networked music performance and how to address the challenges posed by latency over the network. It discusses how the human ear can perceive sounds separated by 20ms or less as simultaneous. For smooth musical interaction, latency needs to be on the order of tens of milliseconds. It also explores different approaches composers and musicians have taken to deal with latency, such as composition techniques, structured improvisation, and graphic scores. Complementary feedback modalities like visual and haptic can help compensate for latency. The document concludes with basic principles for shared sonic environments and remote performance under latency conditions.
1. The document discusses system calls from the user's perspective, providing a high-level overview of common system call categories like process management, file I/O, and directory management.
2. It explains that system calls provide a controlled entry point for applications to make requests to the operating system kernel to perform privileged operations.
3. Examples of system calls on different platforms like Linux, Windows, and MIPS are provided to illustrate the concept.

Virtual memory allows processes to have a virtual address space that is larger than physical memory by using pages to map blocks of virtual memory to physical frames, with a memory management unit and page tables handling the translation between virtual and physical addresses and enabling swapping pages to disk when they are not resident in memory. A translation lookaside buffer caches recent translations to improve performance by avoiding having to access slower memory for every virtual memory reference.

Cities need to update their plan as a number of new concepts have been arising for the last 2 years. Cities need to understand which of those concepts are key, which ones need to be included and whixh ones are complements to the city strategy
