Improving Software Defect Prediction Using Cluster Undersampling

ABSTRACT Adequately learning and classifying datasets that are highly unbalanced has become one of the most challenging tasks in Data Mining and Machine Learning disciplines. Most datasets are adversely affected by the class imbalance problem due to the limited occurrence of positive examples. This phenomenon adversely affects the ability of classification algorithms to adequately learn from these data to correctly classify positive examples in new datasets. Data sampling techniques...

Strategies For Optimizing Password Management Against Versatile Attacks

Managing passwords is a significant problem for most people in the modern world. Passwords are a critical part of information and network security. Passwords serve as primary authentication method to protect user accounts but a poorly chosen password, if compromised, could put the entire network at risk. Many users do not understand why good passwords and password management are important for information systems. “We’re secure! We use passwords!” How many of us have heard this clai...

Design Of Effectively Efficient Techniques For Circumvent Wireless Network Security Threats And Attacks

  ABSTRACT The rapid increase in computer, mobile applications and wireless networks has globally changed the features of network security. A series of Internet attack and fraudulent acts on companies and individual network have shown us that open computer networks have no immunity from intrusions. The traditional way of protecting computer networks, such as firewalls and software encryption are insufficient and ineffective. The wireless ad-hoc network is susceptible to ...

Development Of Biomass Wastes Briquette Stove For Domestic Use

ABSTRACTBiomass energy in the form of woodfuel and charcoal contributes close to 68% of the total energy demand in Kenya. The continued depletion of biomass resources has led to the use of agricultural residue to supplement energy needs for domestic cooking. Biomass stoves used to burn these fuels in Kenya are characterized by high inefficiencies and high emissions that pose environmental and health risks to the users. This research aimed to reduce biomass fuels consumption, reduce fuel indoo...

Development Of A Smart Energy Management System In A Community Based Microgrid

ABSTRACT In this work, an expert system for energy management in community based microgrid was developed. This was necessitated in a bid to address the inadequate power supply predominant in sub-Saharan African countries, while also addressing the problem of energy wastage that comes from individuals supplying their own energy demands. To achieve this, an architecture for a microgrid network was developed by adopting existing standards in the geographical region of interest. An energy ...

Design Of Community Informatics Social Network Web Application: A Case Study Of Niger Delta Region Of Nigeria

ABSTRACT In this research, Social Network Web Application (SNWA) was developed and tailored for a specific use; community development in the Niger Delta region of Nigeria. In the SNWA development, preliminary context analysis was conducted to capture contextual information on community development challenges in the Niger Delta and the readiness of the target local community to adopt web-based solution to the identified challenges. Subsequently, User-Centered Requirement Engineering, Us...

Data Mining And Knowledge Discovery In Database For Improved Industrial Safety

Abstract Safety is crucial in oil and gas industries, it is normal practice to collect incident reports daily. The volume of such reports is always very huge, as a result, the interpretation poses a great challenge. Consequently, there is an urgent need for techniques that can intelligently assist in transforming such vast amount of data into useful information and knowledge. Data mining is part of the knowledge discovery process that offers ways of extracting non-trivial, previously un...

Analysis Of Transmission Control Protocol (TCP) And Its Performance Enhancement Methods On Wireless Networks

ABSTRACT Transmission Control Protocol (TCP) is the dominant transport protocol in the Internet and supports many of the most popular Internet applications, such as the World Wide Web (WWW), file transfer and e-mail. The recently developed advanced wireless networks, such as GPRS, are known to cause delay spikes in packet transfer which causes unnecessary TCP retransmission timeouts. In order to find solutions to this effect, packet losses across wireless links should be distinguished f...

A Tool For The Simulation Of Stream Processing Tasks On Two Dimensional Processor Arrays

ABSTRACT A tool for the simulation of stream processing tasks on two dimensional processor arrays is developed in this work. The tool, a Many-core Energy and Latency Estimator (MELE) has provided abstractions from the many design constraints facing application developers on Many-core platforms. A set of models have been designed to improve the programmer’s ability to iteratively map data flow applications to the target machine. Included in the model set are; an application model, wh...

Adaptive Hybrid Collaborative Filtering Recommendation System (AHCF)

ABSTRACT Recommendation systems play a vital role in boosting the organization’s profit, especially for ecommerce platforms such as Amazon. These systems focus on targeting specific products to users and predicting user preferences and interests. However, recommendation systems are plagued with many challenges, such as adapting them to changes in user preferences and taste, and the effectiveness of recommendations made also determines the ability to retain and engage new users, as new ...

Hybrid Cluster-Based Sampling Technique For Class Imbalance Problems

ABSTRACT Class imbalance problem is prevalent in many real-world domains and as such has become an area of increasing interest for many researchers. In binary classification problems, imbalance learning refers to learning from a dataset with a high degree of skewness to the negative class. This phenomenon causes traditional classification algorithms to perform woefully when predicting positive classes with new examples. Data resampling is among the most commonly used techniques used to ...

Fingerprint Based Students' Attendance System

ABSTRACT Attendance is typically a list of people present at a particular event. Manual approach of attendance taking has not been very effective due to difficulty in keeping the attendance list over a long period of time, unnecessary time wastage during writing or signing, improper documentation, students forgetting to write or sign-the attendance paper among others. The aim of this project is to develop a technology assisted attendance system that will enhance efficient and effective ...

Design And Implementation Of Anti-Theft Vehicle Tracking System With Android App

Abstract The number of car theft increasing each year. If not recovered soon, stolen vehicles are generally sold, revamped or even burned if the resale price is considered to be too low. Once a vehicle is stolen, it becomes hard to locate it and track it, which considerably decreases the chances of recovering it. Nowadays, insurance companies suggest to their clients to equip their vehicles with a Global Positioning System (GPS) that can locate in real time their cars all over the coun...

Design And Construction Of An Intelligent Traffic Control System.

ABSTRACTOne of the major problems encountered in rural and urban communities is that oftraffic congestion and accidents at blind spots on the road. Several traffic control systemshas been designed but in most cases it is targeted towards road intersections, T-junctions,and round-abouts, whereas, congestions and accidents on road blind spots is on the rise.This project, Intelligent Traffic Control System is aimed at controlling the traffic at suchpoints. The system function is based on t...
