Unsupervised network intrusion detection systems for zero-day fast-spreading network attacks and botnets

2015

Today, the occurrence of zero-day and complex attacks in high-speed networks is increasingly common due to the high number vulnerabilities in the cyber world. As a result, intrusions become more sophisticated and fast to detrimental the networks and hosts. Due to these reasons real-time monitoring, processing and intrusion detection are now among the key features of NIDS. Traditional types of intrusion detection systems such as signature base IDS are not able detect intrusions with new and complex strategies. Now days, automatic traffic analysis and anomaly intrusion detection became more efficient in field of network security however they suffer from high number of false alarms. Among all …

Electronic Energy Meter Based on a Tunnel Magnetoresistive Effect (TMR) Current Sensor

2017

In the present work, the design and microfabrication of a tunneling magnetoresistance (TMR) electrical current sensor is presented. After its physical and electrical characterization, a wattmeter is developed to determine the active power delivered to a load from the AC 50/60 Hz mains line. Experimental results are shown up to 1000 W of power load. A relative uncertainty of less than 1.5% with resistive load and less than 1% with capacitive load was obtained. The described application is an example of how TMR sensing technology can play a relevant role in the management and control of electrical energy.

Intelligent Tutoring System in Archaeology

2019

A method that uses artificial intelligence for the taxonomical characterization of bone remains in archaeological sites is shown. The main goal of this method is to help students and archaeologists in the classification of samples in order to improve the efficiency of their tasks during the campaigns at archaeological sites. The development of the system implies several steps: training of classification algorithms, development of a user-friendly interface and implementation of gamification techniques to improve learning motivation and the efficiency of the system in the learning process. This system will help archaeology students to classify new samples. In this prototype, by introducing ch…

Demonstrating measure-correlate-predict algorithms for estimation of wind resources in central Finland

2010

In this study, measure-correlate-predict (MCP) algorithms - Simple Linear Regression and Variance Ratio Methods - for predicting wind speed were studied. The MCP algorithms were successfully used to predict missing wind speeds at two sites in Jyväskylä and Viitasaari, respectively. These two algorithms used data from one of the site to predict missing wind speed data at the other site. The results obtained using the MCP methods were compared using metrics that showed the characteristics of the predicted data to be unbiased compared to measured data. From the data of this study, we also evaluated wind power density at both sites which categorized the local wind resources as poor since the de…

The effect of a failure and submaximal blood flow restriction resistance exercise protocol on changes in muscle size, strength and swelling

2016

Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Introduction: Blood flow restricted resistance exercise (BFRRE) can induce rapid increases in muscle size, strength and swelling. No previous research has investigated the importance of conducting BFRRE to voluntary failure and few studies has been carried out to investigate associations between swelling and muscle size. Therefore, the aim of the present study was twofold (1) compare changes in muscle size and strength between a failure (FA) and submaximal (SU) BFRRE protocol (2) investigate associations between swelling and muscle size. Methods: Seventeen untrained men had their legs randomized to FA and SU protocols. The interv…

Neksusanalyysi suomen kielen oppimisesta siivoustyössä

2017

This dissertation focuses on Finnish language learning opportunities in cleaning work, which is the most common job for immigrants in Finland. The study investigates what opportunities and constraints there are for Finnish language learning in cleaning work, how a work community supports language learning, and what factors facilitate or constrain investment in language learning at work. Language learning opportunities are explored from an ecological approach as affordances – the reciprocal relations between an individual and his/her social and physical environment. The study also explores the scaffolding provided by the work community and investment in second language learning. Nexus analys…

Video Recruitment : Online Perspectives and Implications for Employer Branding

2022

Video recruitment—the use of videos at any point in the recruitment process—has surged among organizations as a strategy for hiring talent and operating in their respective fields amid the pandemic. In particular, video interviews have become mainstream at the assessment stage of the recruitment funnel to keep hiring workers in a remote context of work. Among job video interviews, the asynchronous type especially raised interest and concerns online. This chapter offers a novel and essential approach to the study of video interviews through the theoretical exploration of the crossover between HRM, marketing, and information technology, with the goal of uncovering several ways that employer b…
