architecture and the city. For example, Lincoln Road is a defined and noticeable Strip in Miami, full of shops, restaurants and business. This street is only accessible by a walkable path, yet, it attracts tourist and residents every day of the year. The MiMo architecture and the program of Lincoln Road is not clearly visible from its adjacent streets, however, the owners of the business have managed to implement colorful signage to bring people

Chapter 2 2.1 Fuzzy Logic Controller Fuzzy logic is a type of multi valued logic. It deals with approximate reasoning rather than precise. Fuzzy logic derived from fuzzy set theory. Fuzzy logic was first proposed by Lotfi Zadeh in 1965. Fuzzy logic has currently used in control theory, artificial intelligence systems specially to control complex aircraft engines and control surfaces, helicopter control, messile guidance, automatic transmission, wheel slip control

energy detector, cyclostationary and matched filter methods. A concise introduction and theoretical background of various spectrum sensing methods based on their operation, and drawbacks. KEYWORDS Spectrum sensing, cooperative spectrum sensing, MIMO, Cognitive radio Dynamic Spectrum Access (DSA), Primary User (PU), Secondary User (SU), Software Defined Radio (SDR) 1. INTRODUCTION In the context of wireless communications, spectrum sensing

higher than the performance of classic Wi-Fi. The increase in the transmission speed in the IEEE 802.11n standard is achieved, firstly, due to the doubling of the channel width from 20 to 40 MHz, and secondly, due to the implementation of MIMO technology. MIMO (Multiple Input Multiple Output) technology involves the use of multiple transmit and receive antennas.

switching timing of LED component. Switching speed of an LED can be much faster than a Wi-Fi frequency, with a much larger potential to carry data. Additionally, a polarization can be used for even faster in MIMO type system, as polarizing light is much easier than a radio wave. Thus, in a MIMO system that has multiple transmitters e.g. LEDs and receivers e.g. photodetectors (PD) are used to improve the data rates, significantly security as well as easing of deployment. Bit rates of Li-Fi Compare

1. List two advantages of wireless networking. User mobility in the workplace, and cost effective networking media for use in areas that are difficult or too costly to wire. 2. What are the three areas defined for the IEEE 802.11 standard? Physical Layer (PHY): The method of transmitting the data, which may be either RF or infrared (although infrared is rarely used.) Medium Access Control (MAC): The reliability of the data service, access control to the shared wireless medium, protecting the

Tablet Computer – IPAD MINI Tablet PC is another mobile PC for mobile users. The tablet form factor is typically smaller than a notebook computer but larger than a smart phone. It is highly compact and easy to carry. Tablet PC mainly uses the screen for both input and output. Additional features may include speakers, microphones and cameras. It is a wireless personal computer in the form of a notebook and that allows a user to hand-write notes with a stylus or digital pen on a touch screen.

Software development tool To help counter terrorism, many countries are planning the development of computer systems that track large numbers of their citizens and their actions. Clearly this has privacy implications. Discuss the ethics of developing this type of system. Ethics is a concern of humans who have freedom of choice. Ethics is about individual choice: When faced with alternative courses of action, what is the correct moral choice? What are the main features of ethical choice? Software

INTRODUCTION: Now industry tends towards multi-core processor architecture rather than single core. Many new applications are multi-threaded like Database servers, Web servers, Compilers, Scientific applications like CAD/CAM. In multi-core microprocessor two or more chips called cores shared same processor die. It seems that computer has different independent separate processes. CPU-IC has one or more chips which have separate ALUs and L1 caches. These cores share some memory inside the CPU die
