In Northern Ireland this new generation, which is not visible to, or controllable by, the system operator, is presenting major challenges for accurate load forecasting. Currently deployed load forecasting methods are struggling to cope due to the rapid growth in this new generation, and its weather dependent nature. In this paper linear load forecasting methods are investigated within a sliding window parameter updating framework, which is adopted to address the non-stationarity of the problem. Initially, models are built using historical load terms selected based on correlation analysis of recorded load data. Then, Forward Selection Regression is used to choose the most important variables from a candidate set, consisting of historical load variables and a range of weather related parameters. Model performance is evaluated on load data for the period 2015–2016. A 7-input model, with parameters updated on the basis of a 5-day sliding window of historical data, is shown to yield optimal results, with a mean absolution percentage error of 2.4%.","PeriodicalId":170320,"journal":{"name":"2017 28th Irish Signals and Systems Conference (ISSC)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126333387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This offers significant advantages over existing student response systems, such as Clickers, which are limited in their input capabilities and generally only allow for a multiple-choice selection. In contrast, UniDoodle caters for writing equations, drawing diagrams, annotating figures or any form of graphical input. The key focus of this paper is to evaluate the use of this response system in an active classroom environment over an extended period of time. Fundamentally, we wish to address the following key questions in relation to UniDoodle: do students find it easy to use; do they find it beneficial to their own learning; does the lecturer find the sketch-based student responses beneficial; and how does the use of this response system affect the typical classroom lecture? Here, UniDoodle was used in a first year Systems and Control module, in the Dept. of Electronic Engineering in Maynooth University, for the duration of an entire semester. This paper will present an outline of the UniDoodle system and its key features, details of the actual evaluation with some sample questions, and a summary of the student and lecturer feedback obtained.","PeriodicalId":170320,"journal":{"name":"2017 28th Irish Signals and Systems Conference (ISSC)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128734978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key function of structured databases is to house authentication credentials that verify identity and allow users to access more salient personal data. Authentication databases are frequently a target of attack as they potentially provide an avenue to commit further, more lucrative crimes. Despite the provision of industry standard best practice recommendations from organisations such as Open Web Application Security Project (OWASP), Payment Card Industry Security Standards Council (PCI-SSC), Internet Engineering Task Force (IETF) and Institute of Electrical and Electronics Engineers (IEEE), often practical security implementations within industry flounder. Lacking or substandard implementations have cultivated an environment where authentication databases and the data stored therein are insecure. This was demonstrated in the 2016 exposure of a breach experienced by Yahoo where approximately one billion user credentials were stolen. The global technology company was found to be using obsolete security mechanisms to protect user passwords. Dated implementations such as these pose serious threat as they render authentication data highly vulnerable to theft and potential misuse. This paper offers a novel solution for securing authentication databases on non-compliant Apache servers. The method applies the recommended best practice mechanisms in the form of salt, one-way encryption (hashing) and iterations to both pre-existing and newly created passwords that are stored on insecure systems. The proposed solution can be implemented server-side, with little alteration to the existing infrastructure, unbeknownst to the user. It possesses the potential to improve system security, aid compliance, preserve privacy and protect users.","PeriodicalId":170320,"journal":{"name":"2017 28th Irish Signals and Systems Conference (ISSC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115719725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
