Advanced performance monitoring for self-healing cellular mobile networks

2015

This dissertation is devoted to development and validation of advanced per- formance monitoring system for existing and future cellular mobile networks. Knowledge mining techniques are employed for analysis of user specific logs, collected with Minimization of Drive Tests (MDT) functionality. Ever increas- ing quality requirements, expansion of the mobile networks and their extend- ing heterogeneity, call for effective automatic means of performance monitoring. Nowadays, network operation is mostly controlled manually through aggregated key performance indicators and statistical profiles. These methods are are not able to fully address the dynamism and complexity of modern mobile networks. Se…

Optical Monitoring of Microplastics Filtrated from Wastewater Sludge and Suspended in Ethanol.

2021

The abundance of microplastics (MPs) in the atmosphere, on land, and especially in water bodies is well acknowledged. In this study, we establish an optical method based on three different techniques, namely, specular reflection to probe the medium, transmission spectroscopy measurements for the detection and identification, and a speckle pattern for monitoring the sedimentation of MPs filtrated from wastewater sludge and suspended in ethanol. We used first Raman measurements to estimate the presence and types of different MPs in wastewater sludge samples. We also used microscopy to identify the shapes of the main MPs. This allowed us to create a teaching set of samples to be characterized …

Exercising exclusions: Space, visibility, and monitoring of the exercising fat female body

2019

The author’s aim is to inspect the position of the fat (female) body in the field of exercise. Specifically, the author is interested in fat women’s experiences of their treatment while exercising in public, and argues that, in particular, public spaces for exercise, such as gyms and swimming pools, are currently discursively and concretely constructed as “exclusive” spaces for the normative bodied. Bodies that are deemed non-normative, such as fat bodies, are often made either invisible or intolerable in the discourse of physical activity and exercise. Consequently, public spaces for exercise such as gyms or swimming pools are seen as out of bounds for non-normative bodies and this is refl…

Validity of three smartwatches in estimating energy expenditure during outdoor walking and running.

2022

Commercially wrist-worn devices often present inaccurate estimations of energy expenditure (EE), with large between-device differences. We aimed to assess the validity of the Apple Watch Series 6 (AW), Garmin FENIX 6 (GF) and Huawei Watch GT 2e (HW) in estimating EE during outdoor walking and running. Twenty young normal-weight Chinese adults concurrently wore three index devices randomly positioned at both wrists during walking at 6 km/h and running at 10 km/h for 2 km on a 400- meter track. As a criterion, EE was assessed by indirect calorimetry (COSMED K5). For walking, EE from AW and GF was significantly higher than that obtained by the K5 (p < 0.001 and 0.002, respectively), but…

Improving statistical classification methods and ecological status assessment for river macroinvertebrates

2016

Aquatic ecosystems are facing a growing number of human-induced stressors and the need to implement more biomonitoring to assess the ecological status of water bodies is eminent. This dissertation aims at providing tools to reduce the costs and improve the accuracy of freshwater benthic macroinvertebrate biomonitoring. To improve the cost-e ciency, we consider automated classi cation and develop a novel classi er suitable for complex macroinvertebrate image data. To enhance the accuracy of macroinvertebrate biomonitoring, we study the statistical properties of the Percent Model A nity index crucial to current Finnish biomonitoring and the factors a ecting these statistics. Finally, we perfo…

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 …

Employee personal Internet usage in the workplace

2016

Information technology (IT) devices connected to the Internet, such as computers, tablets, and smartphones, have become pervasive in the workplace. These IT devices have greatly facilitated the performance of job tasks for employees. At the same time, employees are increasingly using these technologies for non-work-related purposes during office hours, which is called personal Internet usage in the workplace (PIU). Examples of PIU include, but are not limited to, checking and sending non-work-related emails, surfing news sites, visiting social network sites, e-banking, stock trading, and online shopping, chatting, and gaming. Previous studies on PIU present two schools of thought on PIU out…
