1. Implementing Remote Laboratories for Digital Electronics: Foundations for Distance Learning and Resource Sharing [Download PDF]

Abstract:

This paper describes the design, implementation and development of a remote laboratory for digital electronics. The laboratory uses the MIT three-tiered iLab architecture, a framework for remote lab development and deployment. This specific experiment involves using a simple encoder-multiplexer circuit connection where users will be required to determine an unknown input to the multiplexer. Not much emphasis is placed on the details of digital electronics, but rather it serves as a proof of concept for how remote/online laboratories can be implemented and adopted in any engineering/science discipline. This paper also introduced a new approach to presenting remote experiments to distance learning students in order to give them an experience similar to what students who have access to the physical laboratories have.

2. Hooking-up Through the Use of Mobile Applications [Download PDF]

Abstract:

The purpose of this study was to uncover how university students are hooking-up through the use of hook-up mobile apps. To achieve this, interests, sexual behaviours, motivations, and emotions associated with hooking-up and the use of hook-up apps were examined. The study revealed several gender differences in motives for using hook-up apps. The main finding was that females scored higher than males on sexual-motives when using a hook-up app. Furthermore, women expressed more feelings of positive emotions prior to using hook-up apps than men. There was no gender difference in the first four factors (i.e., social-sexual, social-relationship, enhancement, and coping) extracted in regards to motives for hooking-up, but there was a gender difference in the fifth factor, conformity. Women were more likely to rate higher on conformity (e.g., "I hook-up because my friends do") for their motivations when engaging in a hook-up. Moreover, it was found that males were more interested in hooking-up than women. Interestingly, both men's and women's opinion of someone who engaged in a hook-up was neutral. In other words, both men and women neither rated a person who participated in hooking-up positive nor negative. These findings suggest that hooking-up is becoming more accepted within our society.

3. Real time calibration of DDoS blocking rules for Web Servers [Download PDF]

Author:

Abstract:

Protecting web servers from Distributed Denial of Service (DDoS) attacks in real time is a critical challenge for any security system. Several methods have been proposed to differentiate attack traffic from normal human traffic and flash traffic but the normal result is to punish both the attack traffic and at least the legitimate (and possibly profitable) flash traffic. This research has developed a novel, adaptive, real-time scoring algorithm to provide a dynamic and effective detection mechanism for a web server. A very occasional "Are You a Human" (AYAH) page is used to calibrate detections rules which are then applied to the rest of the traffic. The real-time scoring system is implemented on an Apache web server and uses shared memory to interact with a daemon to stop, slow, or allow a user request.
