SmartCrowding™ : Bruk av SmartCrowding™ i komplekse situasjoner ved Stavanger Universitetssykehus
2019
Masteroppgave helse- og sosialinformatikk HSI500 - Universitetet i Agder 2019 Background: Over the past years, over-filled hospital wards, critical and complex situations has created an increased amount of difficulties in Norwegian hospitals. This is also true for Stavanger University Hospital. In order to better tradethese challenging situations, Stavanger University Hospital decided to implement «plan for høy aktivitet»(«plan for high activity»), and «Smartcrowding™» as Multi Criteria Decision Analyses Software. The intended purpose of these tools is to ensure a higher level of patient safety, as well as to generate a common understandingof the activity level at Stavanger University Hospi…
Brukeradopsjon av ACOS Individuell plan hos plankoordinatorene : En studie med kombinerte metoder om påvirkningsfaktorer for plankoordinatorenes bruk…
2018
Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2018 Individual care plan is a comprehensive plan to assist users in need of long-term and coordinated services. Individual care plan is one of several service areas in the municipality digitized for better flow of work procedures, lower costs and increased user involvement. The ACOS IP program enables electronic IP in the municipalities. The study has investigated which main factors affect the plan coordinators user adoption of ACOS IP. User adoption looks at why and how a program is used. The purpose is to look at it from the plan coordinator's perspective, but also how the management at the coordinating unit's fra…
WiHAR : From Wi-Fi Channel State Information to Unobtrusive Human Activity Recognition
2020
A robust and unobtrusive human activity recognition system is essential to a multitude of applications, such as health care, active assisted living, robotics, sports, and tele-immersion. Existing well-performing activity recognition methods are either vision- or wearable sensor-based. However, they are not fully passive. In this paper, we develop WiHAR—an unobtrusive Wi-Fi-based activity recognition system. WiHAR uses the Wi-Fi network interface card to capture the channel state information (CSI) data. These CSI data are effectively processed, and then amplitude and phase information is used to obtain the spectrogram. In the subsequent step, the time-variant mean Doppler shift (MDS) caused …
Directive local color transfer based on dynamic look-up table
2019
Abstract Color transfer in image processing usually suffers from misleading color mapping and loss of details. This paper presents a novel directive local color transfer method based on dynamic look-up table (D-DLT) to solve these problems in two steps. First, a directive mapping between the source and the reference image is established based on the salient detection and the color clusters to obtain directive color transfer intention. Then, dynamic look-up tables are created according to the color clusters to preserve the details, which can suppress pseudo contours and avoid detail loss. Subjective and objective assessments are presented to verify the feasibility and the availability of the…
Priority Enabled Grant-Free Access With Dynamic Slot Allocation for Heterogeneous mMTC Traffic in 5G NR Networks
2021
Although grant-based mechanisms have been a predominant approach for wireless access for years, the additional latency required for initial handshake message exchange and the extra control overhead for packet transmissions have stimulated the emergence of grant-free (GF) transmission. GF access provides a promising mechanism for carrying low and moderate traffic with small data and fits especially well for massive machine type communications (mMTC) applications. Despite a surge of interest in GF access, how to handle heterogeneous mMTC traffic based on GF mechanisms has not been investigated in depth. In this paper, we propose a priority enabled GF access scheme which performs dynamic slot …
AI-enabled adaptive learning systems: A systematic mapping of the literature
2021
Abstract Mobile internet, cloud computing, big data technologies, and significant breakthroughs in Artificial Intelligence (AI) have all transformed education. In recent years, there has been an emergence of more advanced AI-enabled learning systems, which are gaining traction due to their ability to deliver learning content and adapt to the individual needs of students. Yet, even though these contemporary learning systems are useful educational platforms that meet students’ needs, there is still a low number of implemented systems designed to address the concerns and problems faced by many students. Based on this perspective, a systematic mapping of the literature on AI-enabled adaptive le…
A Hybrid Algorithm Based on WiFi for Robust and Effective Indoor Positioning
2019
Indoor positioning based on the Wireless Fidelity (WiFi) protocol and the Pedestrian Dead Reckoning (PDR) approach is widely exploited because of the existing WiFi infrastructure in buildings and the advancement of built-in smartphone sensors. In this work, a hybrid algorithm that combines WiFi fingerprinting and PDR to both exploit their advantages as well as limiting the impact of their disadvantages is proposed. Specifically, to build a probability map from noisy Received Signal Strength (RSS), a Gaussian Process (GP) regression is deployed to estimate and construct the RSS fingerprints with incomplete data. Mean and variance of generated points are used to estimate WiFi fingerprinting p…
Achieving agility and quality in product development -an empirical study of hardware startups
2020
Context: Startups aim at scaling their business, often by developing innovative products with limited human and financial resources. The development of software products in the startup context is known as opportunistic, agility-driven, and with high tolerance for technical debt. The special context of hardware startups calls for a better understanding of state-of-the-practice of hardware startups’ activities. Objective: This study aimed to identify whether and how startups can achieve product quality while maintaining focus on agility. Method: We conducted an exploratory study with 13 hardware startups, collecting data through semi-structured interviews and analysis of documentation. We pro…
Investigative decision making : the use of storytelling in e-learning for training police students
2019
Master's thesis Multimedia and Educational Technology MM500 - University of Agder 2019 Purpose–“E-learning is not intended to replace the traditional classroom setting, but to provide new opportunities for interaction and communication between students and instructor or teacher” (Zhang et al., 2004). The thesis aimed at discussing this phrase as the major problem statement.Design/methodology/approach–For this research, case study research method with the InstructionalDesign (ID) process was the chosen design and method for designing and consequently developing an e-learning solution. The case study research method with the ID process was found to support the design and development of a succ…
