Title: Design of an Internet Based Security System
(by): Engr Nathan David
Abstract: To acquiesce to the request of man’s need to protect his life, investment, property and to maintain law and order in a society, security systems are employed to achieve these goals. For the effective realization of these goals, the system must be able to incorporate different functions and monitor several activities instantaneously in real time. These activities include access control, motion detection, fire hazard and the ease of monitoring the system via the Internet. The system has a way of monitoring requests for access to the secured areas as well as reacting to intruder attempts. To achieve this, a successful hardware data acquisition unit based on a microcontroller is designed. The data from the hardware unit is connected to the PC via the parallel port interface so as to monitor all status signals in real time. The GUI provides graphic display of the trends from the sensor devices.

Title: Localisation of Zones of Cancer Detection in Prostate Gland Using Ratio Matrix and Radial Scanning of 2D Trans-rectal Ultrasound Images
(by): Dr. Vincent C. Chijindu, V C. Udeze, C C. Ahaneku
Abstract: Original Article Researchers have continued to proffer various solutions to the challenge of delineating from Trans-rectal ultrasound (TRUS) 2D-images of the prostate the regions of desired property. This paper presents an algorithm that categorizes the detected regions suspected to be cancerous, hyper-echoic pixels, in the prostate gland from a 2D Trans-rectal Ultrasound images into three zones. The developed algorithm uses radial scanning of the pixels of the prostate gland image from common seed point both to detect and delineate the suspected cancerous pixels into zones, namely peripheral, transition and central, by applying ratios of the anatomical zones of the prostate gland. Expert knowledge, intensity and gradient features were implemented to delineate regions of interest. MATLAB programming tool was used for creating the codes that implemented the algorithms. Samples of TRUS 2D-images of the prostate for patients with raised PSA values (>10 ng/ml) used in a previous work by Award (2007) were used for testing the algorithm. The test results showed that the algorithm could detect zones of the prostate boundary exhibit image properties for cancer cells and also the percentage of malignancy detected in zones agreed with existing research findings. Comparison of detection results with that of an expert radiologist yielded the following performance parameters; accuracy of 88.55% and sensitivity of 71.65%.

Title: Remote Monitoring of an Arduino Based Home Automation Security System
(by): Engr Nathan David
Abstract: Security in the home has become a very important necessity in recent times. Development and technology comes with increase in risks such as gas leakage, fire. There is also the issue of burglary and theft and these have made some of the most important home safety requirements for people. Detecting an intrusion or a hazard is secondary; however, taking the necessary action immediately is primary. In order to achieve this, the security system is remotely monitored. This paper presents a model for a home remote monitoring system using arduino microcontroller with an OPNET simulated wireless network system. Using various sensors and camera, the arduino microcontroller monitors the security of the environment and reports the results to a remote system over the internet. The wireless network system comprises the local and remote location to the arduino. The WLAN is responsible for connecting various modules on the arduino to the internet and the remote network addresses the access from this location to the arduino.
