21. A Quantitative Microbial Risk Assessment Associated with Cross-Connections in the Drinking Water Network in Combination with Hydraulic Modeling
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Drinking water companies have the technology and responsibility to deliver safe and high-quality drinking water to the water distribution systems network (WDN). However, many events within the WDN, such as cross-connections and backflow, might degrade water quality and pose public health risks to consumers. LÄS MER
22. Modellering av fosfordynamik i Stora och Lilla Ullfjärden
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Algblomningar är ett problem i många svenska sjöar, speciellt när cyanobakterier blommar och producerar cyanotoxiner. En förutsättning för algblomningar är en tillräckligt hög fosforhalt, då fosfor ofta är det begränsande näringsämnet för cyanobakterier. LÄS MER
23. A cloud-based back-end implementation for the CatFish project
M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : At Halmstad University, the CatFish Project aims to measure and report on water quality. The System includes three components, one to measure, one to present, and one to handle data. This thesis explains the development of a cloud-based back-end solution created for the CatFish project. The solution connects IoT devices via the MQTT protocol. LÄS MER
24. Quantification of peat volume change in Northern peatlands : A study of mires capacity to swell and shrink and its relation to mire age and land management
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Peatlands are important ecosystems that provide ecohydrological functions related to carbon storage and cycling, water quality, flood attenuation, and groundwater recharge. One key characteristic that gives peatlands these functions is the capacity to swell and shrink upon wetting and drying, commonly referred to as peat volume change. LÄS MER
25. An implementation of an autonomous IoT system for real-time water quality monitoring with 4G and satellite connection : CatFish - Embedded systems
Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : This thesis is about implementing an Internet of Things system for measuring water quality in rivers and other aquatic environments with an autonomous water drone, where the data from various components are collected and sent wirelessly to the database in real-time. A Raspberry Pi is connected to the internet through a 4G modem and a wireless satellite communication connection called RockBlock for emergency calls and notifications. LÄS MER
