Automated Attendance Essay Example for Free

Automated Attendance Essay There are many cases in which it would be bene? cial for the University of Stellenbosch to be in possession of an automated class register system. Such a system would be of most value to students, who may make use of system reports and statistics to assess their own approach to their studies, and be kept informed about course material covered in classes attended and missed. An automated attendance recording system would be advantageous to the lecturer, by providing data on student attendances which may be correlated with a student’s academic progress. Attendance recording is an important aspect of tests and exams, where a record must be kept of students writing the paper. Finally, such a system could provide evidence of a student’s class attendance habits in cases where the University is accused by a student of providing insu? cient guidance in lectures. In such cases, the University holds no liability if it can be showed that the student was regularly absent from class. Â  Problem De? nition This project is derived from a topic suggested by Mr. H. R. Gerber for the development of an automated class attendance recording device. The device must positively identify students and provide reliable class attendance logs for the bene? t of students, lecturers and the University, as described in the previous section.Attendance logs must be stored on a centralised database in order to generate reports and statistics. Therefore, the device must be able to communicate with a central database server. Students should be able to access information and personalized reports generated by the system for e? ective self-assessment and keeping up to date. Lecturers should be able to view attendance information and be able to add information to the system. The system should also provide appropriate administration interfaces for administering the recording devices and system parameters. Â  Scope and Aims of Project As part of the original project proposal, it was speci? ed that the student identi? cation device make use of RFID scanner technology, and that the device should be able to communicate via wireless with the central database server. As such, using an RFID scanner and wireless communications is part of the project scope, however alternatives to RFID and wireless communication is discussed The scope of this project does not include an in-depth theoretical study on a particular subject. Â  Introduction to Other Chapters Chapter 2 speci? es the design process used, and states design limitations. It includes an analysis of the problem, the design process and a system level analysis. Chapter 3 and 4 contains detailed design considerations for all leaf-node components of this project, as de? ned in chapter 2 Chapter 5 contains testing and integration information. Chapter 6 contains recommendations and a conclusion to the project. Chapter 2 System Analysis and Design The design approach used in this project involves breaking the main system up into subsystems called ’branches’. Each subsystem branch may be broken up further into subbranches, and subbranches may again be broken up into ’leaf-nodes’, which represent the lowest level of subsystems. This method forms a tree-like structure overview of the system as represented in ? gure . In this way, system level analysis and design is done by looking at the overlaying structure of the system, while detail design is limited to the leaf nodes. At the lowest level, components and design methods are chosen based on functional and non-functional requirements and design constraints. Once the lowest levels of sub-systems are designed, they are integrated and tested in a ’Bottom-up’ approach until all subsystem branches are combined into the all encompassing top-level system. In essence, a ’Top-Down’ analysis and design method with ’Bottom-Up’ integration and testing process is used. Figure ow-chart representation specifying the design approach used for this project, with inherent awareness of design constraints and limitations. Focusing on designing subsystems provides an advantage in that once one sub-system’s design is completed, it may be sent in for manufacturing while design of the other subsystems can continue in parallel with manufacturing, which saves time. If one subsystem fails, it can be redesigned without in? uencing other sub-systems, and in this way valuable time is saved.

Statistical Handling Data Coursework on High School Students Essay

Statistical Handling Data Coursework: High School For this handling statistical data coursework I will be investigating the heights and weights of students of years 7 to 11 in High School. Although this is a fictitious school the data is based on a real school. I will look for a trend in the heights and weights of the students to see if the taller they are, the more they weigh. This is my hypothesis. My Null hypothesis is that there is no correlation between height and weight, and my Alternative hypothesis is that there is strong, positive correlation between them. I will then investigate the heights of boys in years 7 and compare them to the girls, and then do the same in year 11. I will then be able to compare these two sets of results. These are my second and third hypotheses. I am carrying this investigation out because from my hypothesis I want to know whether students in the older years should be separated from the younger students in the lunch queues. This could be necessary because if the taller students are heavier, then the shorter ones will get hurt in the queue to lunch since students usually push their way to the front. So if the taller students are the older ones, then the year groups should be separated in the queue in order to prevent anyone getting hurt. In order to carry out this investigation, I will need to collect the heights and weights of all the students in High School between and including years 7 to 11. Instead of collecting the data, I can find the information on an exam board website. This data is reliable because it is provided by the exam board and is based on real students, however, it may be unreliable because it is secondary data, not primary since I am not physically collectin... ...rect guesses. They also provided a lot of inappropriate data such as their names which is inappropriate since isn’t worth investigating. The data could be biased because it was only collected from one school and not from other areas in the country. The data may be biased because there may have been a lot of snack shops or fast food restaurants near the school, which may have affected the students’ weights. I could have investigated further by using more than one school’s data and compared them and I could have had more hypothesise. This would have given more precise results due to a larger range and a larger sample. I could have drawn more graphs and made more calculations to get more accurate results. For example I could have calculated the standard deviation for my three hypothesise to get a more accurate spread of data than the interquartile range.

Class Divide and Unequality in the United States - 829 Words

The US has always been recognized as the one place where there is no divide among people, hence from its founding days it had been based on the fact of classless society of equals (Angus 55), where it focused on getting rid of such culture that was forced upon by the United Kingdom. A famous sociologist by the name of Alexis Tocqueville, at that time described the US as the most democratic nation in the world. But that soon has changed today in modern times, where there is a greater perceptible of classes in the country, only because of vast wealth accumulation by the higher class or as you may rich class. Americans today have a huge disadvantage of opportunities in all fields such as politics, or health care, justice security even in education and income. The way the class is structured in modern time US is the biggest cause of inequality today. This inequality in US is not even acknowledged. When the thought of inequality is either trivialized or brushed as if it doesn’t exi st. Although we can agree there are other economic social inequality among other nations as well, but they are within their own boundries; if we are to compare only first world nations. Deaton Angus a professor at Princeton university stated â€Å"If the topic of class is introduced, it is always dismissed as far left socialism, having no relvance to modern day US capitalism† (Angus 65.).

By the 1900s, giant firms such as Carneige Steel, The Standard Oil Trust, among a few others controlled 2/5th of the nation’s mark eting capital. This resulted in a rapid increase in the number of industrial workers and even though the American society was growing wealthier overall, there were several thousands
