Industrial Internet of Things (IIoT) market is rapidly growing and expected to further expand in the incoming years. To keep up with such a fast pace, new wireless technologies need to be developed to accommodate the huge number of devices expected to connect to the internet. IIoT devices are designed to be low cost devices which operate in low power mode to provide long battery life time. In orde
Currently humanity faces environmental challenges that require political action in order to maintain the integrity of human and environmental systems. However, political authorities are not always ready to make rigorous decisions to support the necessary changes. Thus, social movements as a recognised agent of cultural, political and social change have the power to push for these decisions. Over t
De stjärnor man kan se på himmeln en riktigt stjärnklar natt - omkring 3000 - är bara en bråkdel av alla de som faktiskt finns i universum. Ljuset har en hög men inte oändlig hastighet. Därför kan vi bara se sådant som ligger tillräckligt nära jorden, så att ljuset hunnit färdas hit under universums livstid. De himlakroppar som ligger längst bort ifrån jorden men som fortfarande går att se (med teDoes the formation of planets give imprints on the chemical composition of the host star? In order to test this theory a differential abundance analysis (i.e. comparing two stars' abundances to each other) was carried out on a few stars with and without known planets, to see if any differences were found. The analysis was based on high resolution, high signal to noise ratio (SNR) spectra of fo
To find the optimal by-pass road alignment in the Tlokweng Planning Area in Botswana, a multi-criteria spatial-based model is developed using the GIS-MCE approach. In respect to the environmental impact assessment (EIA) approach, in this research a set of criteria is classified under 3 themes – economic, environmental and social. To determine the criterion and theme weights and perform their aggre
Purpose: The purpose of this research is to contribute to the knowledge about Generation Z in the consumer society context, through a critical investigation of the possible negative impacts of the internalization of the consumerist mentality within the digital capitalist society. This is relevant since such internalization could interfere with the capacity of individuals to maintain long-term rela
Dagens vägskyddsanläggningar är baserade på gammal reläteknik och är byggda på liknande sätt som på 1940-talet. År 2014 påbörjades projekt-Alex av Trafikverket med mål att byta ut dagens vägskyddsanläggningar mot en mer modern och driftsäker anläggning. Detta genom att uppdatera tekniken i vägskyddsanläggningarna till ett databaserat system som ska standardiseras och inte vara så anläggningsspecifToday's level crossing security systems are based on old relay-based technology and have been constructed in the same way since the 1940s. In 2014, Project-Alex was initiated by Trafikverket to replace the current level crossing security systems with a more modern and reliable system. It is done by updating the technology in the level crossing security systems to a computer-based system that i
The social and environmental impacts associated with corporate water use and discharge in Kazakhstan is historically high, and in certain watershed pose a significant threat to the health of the local communities and ecosystems. Today the industries are consuming almost a third of freshwater and remain one of the biggest polluters in the country. The situation is aggravated with the changing clima
With food shortage becoming a growing problem at the same time as the world population increases and cities become more densely populated than ever before, resource efficiency has become a more dire issue than ever. One major problem in food production today is that production efficiency is very weather dependent, transportation is also a big factor in environmental impact and almost half the worl
När man pratar om industriellt underhållsarbete är mänskliga fel ett viktigt ämne att hantera. Olika typer av mänskliga misstag till följd av farliga tillstånd i vissa speciella parametrar, s.k. Performance Shaping Factors (PSFs) introducerar nya och oförutsägbara risker. Detta examensarbete presenterar en metod som, till skillnad från många metoder som finns tillhands idag, är tänkt som en enkel When discussing industrial maintenance, human error is a topic that easily comes to mind. Slips, lapses and mistakes due to hazardous settings of critical conditions referred to as Performing Shaping Factors (PSFs) introduce unforeseen and unanticipated risks. Unlike several tools to date, the methodology presented in this master thesis is thought to serve as an easy and fast way to identify risks
MIMO (Multiple Transmit and Multiple Receive) antenna techniques are widely used in the most recent wireless communication standards. For example, LTE (Long-Term Evolution), WiMAX (Worldwide Interoperability for Microwave Ac- cess) and IEEE 802.11n have recently been rolled out across the world. In any communication system, the ML (Maximum Likelihood) receiver provides optimal error rate performan
In this work, which is to be used as a supplementary example to the educational literature in Automatic Control, at LTH, I have chosen one reactor, in the group of chemical reactors, for the examination. The chosen reactor is the continuos-flow, autothermic, nonadiabatic stirred-tank reactor. Required cooling of the reaction mixture is achieved by letting the reactor-tank be surrounded by a coolin
Backlash is common in mechanical and hydraulic systems. It severely limits the overall system performance. Many mechanical solutions have been developed to overcome backlash, for example by using spring-loaded split gear assemblies or dual motor systems. These mechanical solutions can satisfactorily handle the backlash problem but they give rise to other problems like decreased accuracy and reduce
In this study, Dissolved Organic Matter (DOM) quality was analysed through its optical properties. Samples from the estuarine waters of the Beagle Channel and oceanic ones of the Burdwood Bank were examined in order to understand how DOM quality was changing. The focus of the study was to determine whether the environmental variables or the microbial community were the main driver in DOM compositi
This thesis work is on the theoretical description of dilute Bose-Einstein condensates (BEC) that are non-uniform, meaning that more than one single-particle state is occupied. This phenomenon is usually called quantum depletion. A common model for the ground state of a dilute and weakly interacting BEC is the mean-field (MF) approximation leading to the Gross-Pitaevskii (GP) equation. However, fo
Denna studiens syfte var att undersöka och försöka precisera vad för specifika egenskaper och förmågor hos en psykoterapeut som forskare och teoretiker hitintills har beskrivit vara eftersträvansvärda för att kunna ge en god terapeutisk effekt i psykoterapeutiska behandlingar. Syftet var också att i möjligaste mån skapa en tydlig översiktlig kartläggning och sammanfattning genom att samla ihop mycThe aim of this study was to investigate and try to specify what specific characteristics and abilities of a psychotherapist that researchers and theorists have so far described to be desirable in order to provide a good therapeutic effect in psychotherapeutic treatments. The aim was also to create, as far as possible, a clear overview and summary by collecting as much of material that is currentl
After the major populist events such as Trump and Brexit, the media politicians turned their attention to the socio-economic and political division between big cities and small countryside communities. Rural areas where right-wing populist parties have found a large part of their support have besome “left-behind places", described as forgotten and misunderstood. The question of why these popu
A prerequisite for the effective conservation of species, is the accurate assessment of a species’ distribution and numbers. In order to look into the population sizes of birds, a quantitative atlas project from 1981 included a total count of the inland birds in the Faroe Islands. The aim for my thesis was to look at the population changes from 1981 until 2020, by repeating the 1981 atlas project,
There is a need for harmonisation of stability study designs of monoclonal antibodies. Monoclonal antibodies (mAbs) are widely used in treatments for various diseases. Like all drugs, their quality must be verified through stability studies. The ICH guidelines give general recommendations regarding stability studies of antibodies, and specifications should often be determined on a case-by-case bas
