What is colour? Colour is a small part of electromagnetic waves. Each colour will have its own wavelength and frequency [1]. Colour is a term that cannot define by 2 dimensional or 2 values. Colour requires at least 3 dimensional otherwise it cannot be accurately presented on a 2 dimensional map. There are a lot different models to define colour space and most common colour space is HSV, RGB and CYMK. RGB is a colour space that form by three primary colour which known as red green and blue. By...
Abstract Modern companies depend on being networked, be it wired or wireless, there are always devices that are connected and when looking at the bigger picture, a business relying on it. Many workers lack the ability, knowledge or even simply the time to maintain a completely secure network and often incorporate their own devices in the business's network. This is an investigation into the threat these insecure devices pose, how Microsoft NAP provides several solutions to help protect against...
Auditory Games Audio display concentrates on presenting visual based information in the form of sound. On the topic of audio gaming and referencing Johnny Friberg and Dan Gärdenfors (200-) states: "audio games are computer games that feature complete auditory interfaces, so they can be played without the use of graphics" [1]. A majority of the computer games available are solely designed for sighted users, they tend to focus on visual cues rather than auditory cues [2]. They...
Q1 (a) What is software? Describe the software functionality using software diagram. In simple words, software is that part of our computer system which we cannot see and touch. But it is not comprehensive to tell much about software. Software is actually the set of instructions and codes which are designed to interact the user and the hardware of computer system to let it work as they desire. Programmers design this software according to new technology/systems or on user demand. Without...
Introduction: In order to emulate a DC motor control, vector control strategy is employed to decouple flux and torque of an induction motor. The great advantage of this technique is that the induction motor can be controlled with the presentation of all of its properties such as high efficiency, robustness, low maintenance cost. The most widely employed controller is the conventional proportional integral (PI) controller. The limitation of PI controller can be overcome by introducing the...
The concept buffering a table in SAP is to improve the performance of the table when accessing data records contained in that table. The table buffers reside locally on each application server in the system. The data of the buffered table can be directly used from the buffer of the application server. Thus the to and fro access to the database is avoided and in turn consuming less time and increasing the speed of execution and thus increasing performance.PurposeBuffering is particularly...
This paper describes basic understanding of Wireless LAN IEEE 802.11 technology. Also provides graphs for Media Access delay and Application Response time with understandings of the results using graphical representation and comparisons under three different scenarios for a specified network model using Opnet IT Guru Academic Edition.IntroductionIEEE 802.11IEEE 802.11 is a Wireless Local area network protocol (WLAN) and its associated technologies such as 802.11x and WPA (Wi-Fi Protected...
In recent years the industrial application of advanced control techniques for the process industries has become more demanding, mainly due to the increasing complexity of the processes themselves as well as to enhance requirements in terms of product quality and environmental factors. Therefore the process industries require more reliable, accurate, robust, efficient and flexible control systems for the operation of process plant. In order to fulfil the above requirements there is a continuing...
This research paper discusses on 'Linux Scheduler 2.6' supported by Linux Operating System. Paper describes and explores algorithms and mechanisms that play a vital role in scheduling processes/tasks for Linux OS. It also discusses different constraints and characteristics of CPU scheduler for version 2.6 of Linux kernel and also includes comparison between previous versions. Linux is a highly popular operating system today freely distributed over the internet. There is a fast paced development...
Q1. What are the activities that an Analyst should perform to develop UMS ( University management system).Ans: - Activities done by the Analyst are given below are:-Preliminary Investigation:- First of all they visit the university and notes the important point which is required to make the UMS according to the requirements and they analysis the whole requirements.Determination of system requirements:-Analyst notes the all the important facts of the University by visited the university. And...
