Design and Implementation of An Intelligent System for Detecting and Profiling Good and Bad Credit risk Applicants Project:
Project description: Data Mining/Machine Learning Project: The design and implementation of an intelligent system (a generic data mining/financial software system for classification problems) using Java programming language to implement (code) the distance-weighted K-Nearest Neighbour algorithm (where k could be any number) with an element of probability to increase its accuracy. The system is called the Credit Profiling System and it is an improvement on the simple K-Nearest Neighbour algorithm (a data mining technique). Data mining is a process of finding and extracting hidden knowledge or patterns from large data sets. It adopts a combination of machine learning (a field of Artificial Intelligence) and Statistics. The system detects and predicts which loan or credit applicants (companies or individuals) are likely to be good or bad credit risks. This type of system is regularly used by banks, loan companies and financial institutions. The information gained as a result of using this system would assist them in making decisions about accepting potential customers that would be good credit risks and rejecting the ones that would be bad credit risks. These decisions would help to reduce the losses they suffer as a result of the inability of their credit customers to repay their credit cards, loans and mortgages. The system profiles and classifies loan or credit applicants into two class labels namely: good credit risk (Yes class) and bad credit risk (No class) by analysing the attributes or characteristics of past loan or credit applicants in any data set using induction-based learning.
Coding of a Medical Diagnosis program called “The Cardiolgy Diagnoser” Project:
Project description: Data Mining/Machine Learning Project: Building a diagnostic tool by coding a program in Java implementing the k-Nearest Neighbour Algorithm for k=3. The program called Cardiology_diagnoser.java reads the cardiology_training data set (containing details of patients that were diagnosed by specialists for cardiac problems.) to be used as a training data set, and a second dataset called cardiology_new with new/undiagnosed patients. The program diagnoses each new patient and writes the result in a CSV (comma separated values) file called New_diagnosed_patients.csv, containing the new patients’ details and the computed diagnosis within a row.
Design and Development of a Multi-Threaded Chatting Application Project:
Project description: Internet and Distributed Programming Project: A multi-threaded server system coded in Java that performs multiple computing services such as requesting clients concurrently on separate threads. Such systems, which are widely used in many applications today, rely on the server’s ability to leverage on the multi-threaded functionality of the development platform, operating system and underlying hardware. The client applications will in most cases be remotely located and will communicate with the server over a network, requesting for services and receiving results. The server’s job is to receive these requests, perform the services taking into consideration available resources and priorities, and return the results.
Design and Development of an E-Commerce website Selling CDs – Project:
Project description: Web Development Project: The e-commerce website called Bayo’s eStore, developed using HTML, PHP and SQL, has the following functions:
a. The user logs on with a username and password, which are compared against a text file on the server.
b. If correct, the script displays a table of CDs, artist names and prices from a server-side database. E.g.: (Kind of Blue, Miles Davis, £4.99).
c. The user selects one or more CDs and gives their full name, credit card number and the expiry date.
d. The script validates the number and expiry date; if correct, the DB is updated with a record of the order, and a confirmation message including the total cost is displayed to the user as an HTML page.
e. The user logs off and on again; the script displays a message “Hello <username>. You last logged on at <date and time>.” This works for up to one week after the first session.
Design and Development/Creation of the Teaching Database in PostgreSQL Project:
Project description: The creation and population of the Teaching Database in PostgreSQL using SQL commands and the following table information (SQL: Data Definition):
Student (sid integer, sname varchar(20), programme varchar(4), level integer, age integer)
Class (ccode varchar(6), cname varchar(25), week_day varchar(3), meets_at time, room varchar(6), tid integer)
Enrolled (sid integer, ccode varchar(6))
Tutor (tid integer, tname varchar(20))
The table Student stores data about students registered on some programmes offered by the Computing department.
Each Class identified by the ccode (which is the code) is taught by a Tutor identified by tid. The table Enrolled has one row per each pair student-class, for each student registration in a given class. The table Tutor stores data about the tutors involved in teaching. Note that all the names of students and tutors consist of a string formed from the last name preceded by a first (and possibly a middle) name. The primary keys are underlined.
The foreign keys are chosen to match the primary keys in the corresponding tables in order to make the appropriate links between those tables and to ensure appropriate referential integrity of the data.
Appropriate indexes (one for each of the following columns) are created such that searches on the student and tutor names, and on the class names are to be speeded up. Various SQL queries are then written to query and retrieve data (SQL: Data Manipulation) from the Teaching Databas
Design and Implementation of a Secure Password System (Security System) based on the Vernam Cipher Encryption System Project:
Project description: Computer Security Project: This incorporates the various aspects of computer security such as access control, encryption, cryptosystems, database, security in networks, privacy etc. A secure password system designed and implemented in PHP to encrypt passwords of newly registered users of a website using the Vernam Cipher Encryption System. The encrypted passwords of new users are saved to a file on a database server (MySQL server) on which the details of the users of the website are stored. The website administrator cannot view the actual password.
The Secret of Zankas – Game Project:
Project description: The “Secret of Zankas” is a single player dungeon crawler game in Java. The aim of the game is to get to the final level and find all the lost treasures, thereby completing the dungeon. The player has to survive the levels to find the last level where the treasures are located. Level generator is randomly generated. The game is generated from 15-20 levels and the winning level is randomly chosen from these.
