The development seen within industrial automation in recent years enables the emergence of manufacturing sites that utilise technology for improved productivity, quality and safety. Increased communication demands introduced by Industry 4.0 have motivated the development of cloud-fog automation; a technique characterised by wireless communication between lower levels of the automation pyramid. Spe
The Cosmetic packaging industry is on the rise and through consumer demand, cosmetic companies are increasing their focus on sustainability and accountability. This has left many companies in need of a deeper understanding regarding the environmental impact of their current packaging solutions as well as how to improve their footprint in the future. This thesis addresses these points by providing
Buildings worldwide account for 30% of energy consumption and Heating, Ventilation and Air Conditioning (HVAC) represent roughly 38% of a building’s consumption. Therefore, energy savings are crucial for sustainability. The complexity of buildings, with diverse physical domains and large-scale components, presents challenges to achieving energy-efficient operation. Implementing high-performance co
As supply uncertainties and increased lead times were more prominent than ever during the covid-19 pandemic, many companies experienced disrupted supply chains and realized the weaknesses in their inventory management and supply chain planning. Many organizations, including the case company in this thesis, Beijer Ref, experienced the impact of the bullwhip effect on their operations. The bullwhip
I detta arbete har en Minimum viable product (MVP) för en applikation utvecklats, som gör det säkrare att avveckla och ta bort endpoints för ett REST API. Tidigare arbete har visat att hanteringen av avvecklingen av endpoints i REST API:er är ett problem, där REST API:er inte följer protokoll för avveckling och borttagning. Applikationen är gjord för att tillhandahålla ett enkelt sätt att övervakaIn this thesis - a Minimum viable product (MVP) for an application aimed at making deprecation and removal of REST API endpoints safer - was developed. Previous work has shown that handling deprecations and removal of endpoints in REST APIs is a problem, with REST APIs not following deprecation-removal protocols nor giving the API consumers the information needed to properly update their software.
Understanding the sustainability concept: According to the UN World Commission on Environment,(Borowy, 2013) it is the balance between environment, economy, and equity. The development meets the needs of the present without compromising the ability of future generations to meet their own needs (Rauschmayer et al., 2012). Sustainability is integration of the environmental health, social equity, and
Adsorption is an important separation technique in chemical engineering, capable of achieving a high purity of product. As it is also capable of concentrating even very low concentrations it was investigated as a possible method to concentrate the product of an ammonia plasma reactor in the EU DARE2X project. As the development of adsorption systems is expensive and time consuming, a simulation of
This report describes the research, conclusions, and result of my Master Degree thesis project in Industrial Design at Lund University. The thesis was completed during the spring semester of 2018. The work was carried out in collaboration with Trimble Geospatial in Danderyd, Sweden. The main purpose of this thesis was to explore the future methods of working with geospatial instruments - s
PFAS is a group of long-lasting chemicals with multiple known toxicological effects which has been found everywhere in nature. One of the possible source points of PFAS is via landfill through leachate leaving the area. It is therefore important to investigate and implementing remediation techniques to reduce the contamination risk. This thesis focuses on two components, first a literature study w
In this work, a new method for spectral analysis of irregularly sampled data from paleoclimatology is proposed. The spectral estimate is formulated as an inverse problem and extracts information from multiple cores sampled at different times with different phases, while being robust to errors in the assumed sampling times. The proposed method is also shown to attain the misspecified Cramér-Rao low
Vilken plats har skönlitterärt skrivande i dagens svenskämne i gymnasieskolan? Nästan ingen, av styrdokumenten att döma. Det skönlitterära skrivandets roll har successivt tonats ner, och i dag finns det knappt omnämnt i styrdokumenten. Detta arbete har dels undersökt svensklärares inställning till skönlitterärt skrivande och i vilken grad de inkluderar det i sin undervisning, dels vilka delar i st
As the demand for higher data rates and lower latencies increase, together with the use of higher frequency bands, MIMO and beamforming have become an essential part of the 5G NR technology. Calculating the beamforming weights is a costly process, and reducing the frequency resolution of the weight calculations would save a significant amount of computational power. Which resolution is suitable to
Since the beginning of wireless communication, one of the central problems has been resource management and maximization of network throughput. Solving these recurring issues is an important topic in the field of wireless communication to increase application options and the user experience. The existing methods for solving the issue of inter cell interference by maximizing the network capacity ar
Longitudinal study designs, in which variables of interest are observed at multiple time points in a study population, are frequently used in clinical research. Missing data are common in these types of studies. Moreover, in studies investigating a population where the mortality rate is high, data can be truncated by death. To handle missing or truncated data, it is important to investigate the un
Microfluidic devices have so far not seen widespread use, even though they could potentially be cheaper, better and faster than traditional methods. A possible reason for this is the lack of a middle step between one-of-a-kind experimental devices and cheap mass produced devices. With ongoing improvements in resolution it is starting to look possible that 3D-printing will fill this role. This the
Purpose: To explore why brands lose control over their identity due to internal actions or lack of actions when needed. The paper examines the key elements brands should focus on internally to prevent brand identity erosion which can negatively impact brand performance. Methodology: This paper explains the relevance of brand identity by a literature review and further builds on fundamental causes
Early designs are often based on rough estimations and assumptions. Such is also the case when designing space turbines that power rocket engine fuel pumps which generally have obscure performance and size requirements. Often times, this leads to unique, single-use designs. This complicates and restricts the amount of possible testing. To aid in this early design process and to help predict turbin
