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
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
The cost of developing and researching novel molecular compounds in the pharmaceutical industry is very high today. If an actor accidentally releases too much information about a novel molecule to the public the molecule becomes prior art, and as an effect, can not be patented. This has resulted in a fragmented space where collaboration across organizations is virtually non-existent. We propose a
The thesis aims to understand if seed saving practiced by oppressed small-scale farmers and peasants who are affiliated with Navdanya can be seen as a technology of resistance against the dominant agri-food industrial paradigm. Another aim is to find out how political and cultural meanings are attached to seed saving. It also aims to challenge this aforementioned paradigm. The inquiry is exemplifi
Barn och föräldrars värderingar, underlag för lösningen på ett växande trafik- och samhällsproblem? Resultat från LTH:s nya examensarbete om barns säkra och trygga skolvägar förväntas kunna ge underlag för att minska problemen skapade genom föräldrar som skjutsar sina barn till skolan. Trafiksituationen vid många svenska skolor har beskrivits som kaosartad och skapat många frågetecken för framtidThis master thesis focuses on safe and secure routes to school and the point of departure is the phenomena that parents take their children to school by car instead of using sustainable alternatives as cycling and walking. This behavior creates a number of problems around schools as congestion and lack of traffic safety. Also the roads that are used for traveling to and from school, experience the
Salinisation is a global issue which leads to desertification and soil degradation and exposure to salt is also known to inhibit microbial activity and plant growth. This study was conducted to determine the influence of salinity on microbial activity of a non- saline soil. By using Salt Induced Community Tolerance (SICT) concept I found that microbial community tolerance to salt can be induced in
Purpose: The purpose of this study is to examine the role of the perceived servicescape (i.e. color, music, cleanliness, ambient temperature, layout/function and signs/symbols) in influencing customers' behavioral intentions in Chinese fast food restaurants. Methods: In this study, a deductive approach, a quantitative methodology, and a survey research design are adopted. The data is collected
En kopparlödd värmeväxlare används i fjärrvärmeapplikationer. Ett samhälle under ständig utveckling har lett till en strävan att förbättra dessa produkter, men också till en strävan att minska kostnaden vid både tillverkning och utveckling av nya, effektivare produkter.This Master Thesis has been conducted with the aim to investigate the mechanical performance of an isolated copper braze joint. The mechanical performance of the copper brazed heat exchanger is to a great extent determined by the properties of the copper braze joints. It is not yet exactly known how different parameters such as the weight of copper per joint, plate material composition and furnace
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
Title: Using scenarios to balance future requirements and capability development Author: Erik Jacobsson Division: Production Management Supervisors: Bertil Nilsson at the Technical Faculty of Lund University, Innovation Advisor at the case company Keywords: Scenarios, Corporate development, Energy Sector, Capabilities, Technology Background: The speed of change in the world is ever increasing
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
Lupin seeds contain like many other grains and legumes the mineral inhibitor phytate. The presence of this anti-nutrient decreases the bioavailability of minerals such as zinc and iron. Especially people that live in areas where grains and legumes are the staple food source, as well as vegan and vegetarian groups, may be more vulnerable to mineral deficiencies. The presence of phenolic compounds i
