    Can rural Gaza Strip be both biogas “self-sufficient” and organic waste and wastewater problem free?2013Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The rural areas in the Gaza Strip suffer from the problem of sanitation and organic waste as well as electricity and cooking fuel. In this thesis, the biogas plant was designed to solve those problems based on the fixed dome plant design as shown in Figure 3 and4. Therefore, the efficiency and selectivity was good for biogas plant which is easy for the local people disposal of organic waste and wastewater as well as self-sufficiency of biogas for cooking and electricity for the family. The sediments from the biogas plant are also used as fertilizers in agriculture. Thus it is possible to know the amount of biogas production, the cost of biogas, the amount of fertilizer, the cost of fertilizers and the amount of disposal of organic waste and wastewater. The calculation shows that the size of digester which is equal to 12 cubic meters as shown in figure 4.The construction is cost of $ 930 as shown in Table 2. Through the results will be disposed of organic waste, wastewater and manure are about 48 kilograms per day for the family. The Biogas is produced 0.5 tons of biogas is estimated about $ 100 in rural areas in the Gaza Strip. It is also produced fertilizers equivalent of $ 113 per month. So the results and calculations are clear that the rural family is self-sufficient of biogas, the dispose of organic waste and wastewater and agricultural growth by the fertilizers from the biogas plant.

    Innemiljö i nytt ljus: metoder för objektiv bedömning av belysning2017Report (Other academic)
    Abstract [en]

    Current standards for lit environments are solely based on technical requirements, e.g. brightness, uniformity and luminance. Including experience-related requirements would most likely promote better lighting comfort as well as more energy efficient lit environments and lighting products. However, lack of knowledge on how to describe perceived lighting parameters hampers users and building owners in specifying desired lit environments and for lighting manufacturers to develop products for new markets. The aim of this research project was to apply and develop sensory methods for lightning. In contrast to previous methods for subjective lighting assessment sensory methods enable objective assessment of perceived lighting parameters.An analytical panel comprising eight persons fulfilling specific selection criteria were recruited and trained to assess lighting products in a multi-sensory laboratory at SP Technical Research Institute in Borås. During the development special emphasis has been given to improvements of the training procedure, handling the adaptation of the eye, and assessment of colour and shading. Besides laboratory assessments, the feasibility of analytical assessment in a real context was examined. The same experimental set up and panel was used.The results show that it is possible to apply sensory methods to lighting to objectively assess luminaires; the panellists were able to distinguishing between attributes and samples. Significant differences were identified between the different luminaires, both in terms of sensory and physical properties, e.g. readability and glare. However, physical and sensory parameters do not always co-vary, which shows that physical and sensory measuring methods provide complementary information about the lighting quality. Furthermore, assessment in a real context provided the same, but less significant, results as in the laboratory.In the future, the knowledge may be applied in tools supporting the communication between different professions in lighting design and procurement to promote more desirable and energy efficient lit environments.

    Om organisering av det regenerativa arbetet: samtal om roll, process och interaktivt meningsskapande 2010Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The focal point of this thesis is an interest in the phenomena of regenerative work, which is a work that has the potential of recreating and developing human resources and energy. The aim is to make a contribution, by presenting a supplementary perspective, to this area of research by considering regenerative work through a process perspective where the centre of interest is transferred from being a question of what to a question of how? The guiding research question is as follows: How could the organizing processes of regenerative work be understood? - more specifically - through an interactive approach the purpose is to describe, analyze and understand those everyday processes that have implications for regenerative work.

    This general inquiry took place at a number of wards/departments at a hospital in southern Sweden. Above all, the empirical focus concentrated on two specific occurrences: (1) an implementation of a new work model at the various wards/departments and (2) the function of the ward managers and their work situation. Empirical material was collected in collaboration with assistant nurses, registered nurses and ward managers through forum dialogues, interviews and observations. Narratives as formation of knowledge are a significant tool that constitutes an important foundation of this thesis. The chain of events and actions of complex processes are thus interpreted and understood by means of using narratives as a research device. The narrative form was also a source of inspiration for a large portion of the results presentation.

    The comprehension of the construction of experiences that may be related to regenerative work must be interpreted and understood beyond an individualistic perspective. Overconfidence in rules and routines, and a predetermined execution of the work proved also to be problematic in a complex and symbolically charged reality. Consequently, regenerative work must be understood in the light of a reality/world that consists of regularities and irregularities as well as predictability and unpredictability. It is in the complexity of such worlds, actors are required to interpret what their work/assignment is about and to carry it out satisfactory and to the best of their ability. Hence, two crucial questions are derived: How is the work/assignment interpreted? Are their prerequisites in the organization enabling and supporting good performances? In conclusion, these two questions are interconnected and discussed further in view of local basic conditions for conversation and action as well as leadership in terms of organizing for sensemaking.

    Toward outcome-based approaches in higher education in two nordic countries2021In: Public sector reform and performance management in developed economies: Outcomes-Based Approaches in Practice / [ed] Zahirul Hoque, Routledge, 2021, 23Chapter in book (Other academic)
    Abstract [en]

    In recent decades, modernization efforts by public sector organizations have been driven by neoliberalism principles, while simultaneously focusing on performance measurement and management systems (PMMS). These systems are expected to promote a stronger emphasis on effectiveness, quality, and outcomes. Based on a documentary analysis, this chapter investigates how PMMS within higher education in Finland and Sweden have defined, measured, and managed outcomes and effectiveness. The findings shed light on converging and diverging trends and the potentialities and challenges of outcome-based approaches and provide scholars and practitioners with insights into the current development and key features of such systems.

    Utveckling och tillämpning av sensoriska metoder för objektiva belysningsbedömningar, del I2017Report (Other academic)
    Abstract [sv]

    I dag finns tekniska belysningsstandarder som inkluderar parameterar så som ljusstyrka, jämnhet och luminans. Det som saknas är krav som grundar sig på människors upplevelser av belysning och ljusmiljöer. Att få med den upplevelsebaserade dimensionen skulle betyda ett helhetstänk som förmodligen skulle gynna både ljuskomforten och än mer energieffektiva ljusmiljöer och produkter. Att beskriva upplevda belysningsparametrar har hittills visat sig inte vara helt enkelt, och här saknas både kunskap och en gemensam begreppsvärld inom branschen; något som hämmar fastighetsägare att ställa lämpliga krav vid en upphandling liksom belysningstillverkare att utveckla produkter för nya marknader och tillämpningar. Det övergripande syftet med detta forskningsprojekt är att utveckla och tillämpa sensoriska metoder på belysning. Till skillnad från tidigare metoder möjliggör sensoriska metoder objektiva bedömningar av upplevda belysningsparametrar. Syftet med försöken som redovisas i denna delrapport är att vidareutveckla och testa metoden ytterligare. Detta görs genom att nya armaturer testas liksom att försök utförs i en ny verklig kontext (kontorsmiljö). Försöken bygger vidare på resultat från tidigare försök som har rapporterats om i (Boork et al, 2017).En analytisk panel bestående av åtta personer, som uppfyllde särskilda urvalskriterier, har tidigare rekryterats och dessa personer tränades nu för detta specifika delprojekt för att bedöma belysningsprodukter i ett multisensoriskt laboratorium på RISE Research Institutes of Sweden i Borås. Metodutvecklingen fokuserade särskilt på en effektiv träningsprocedur, hantering av ögats adaption, samt bedömning av färg och skuggningar. Förutom laboratorieförsök undersöktes möjligheten att genomföra analytiska bedömningar i en verklig kontext med samma försöksuppställning och panel.Resultaten visade att det är möjligt att använda sensorisk metodik för att genomföra objektiva belysningsbedömningar även för de testade belysningsprodukterna, dvs mindre LED-spotlights. Signifikanta skillnader identifierades mellan de olika armaturerna och som i tidigare försök spelade färgtemperaturen en stor roll för flera av de bedömda egenskaperna; inte minst förstås för ljuskällans gulhet och för läsbarhet (textkontrasten). Liksom i tidigare försök fanns det samband mellan de fysikaliska mätningarna och sensoriska bedömningarna, men inte för alla egenskaper, vilket visar att fysikaliska och sensoriska mätningar ger kompletterande information om belysning. Vidare visade bedömningsförsök i en verklig kontext att likvärdiga resultat uppnåddes som i laboratoriet, om ändock något spretigare och inte heller lika entydiga i jämförelse med verklig kontext i tidigare försök.Den genererade kunskapen väntas på sikt bidra till utveckling av verktyg som stödjer kommunikationen mellan olika professioner inom ljusdesign och planering och på så vis främja mer önskvärda och energieffektiva ljusmiljöer.

    Increased precision in the mounting and the running-in process of sheet metal forming tools with use of the non-destructive testing method acoustic emission2009In: Proceedings of The International 3'rd Swedish Production Symposium, Göteborg, Sweden, 2-3 December 2009, 2009, , p. 447-454p. 447-454Conference paper (Other academic)
    Abstract [en]

    Mounting and adjusting of tool parts or correction of blank holder forces in deep drawing operations can be optimised by minimising acoustic emission due to influence of boundary layer friction and wrinkling. Critical friction surfaces can be monitored with consideration to the wear of the friction surfaces. The momentary acoustic emission contains information about the status of wear at the friction surfaces and if the wear is a wear-in or a wear-out process.

    Unexpected events like fractures and galling results in distinct and abnormal increase in acoustic emission. The acoustic emission contains information that can be used to improve or monitor the forming operation. These conclusions are results from studies of different forming operations and measuring of acoustic emission in the forming tool both at the productions lines at the sheet metal forming industry and laboratory tests at Lund University.

    The author professor Jan-Eric Ståhl is responsible for the education of Masters and doctoral degree at the department of Production and Materials Engineering, Lund University. He has long experience of applied research in the area of mechanical engineering. Thomas Skåre, PhD, is lecturer in mechanical engineering at the Kristianstad University College and has experience from the area of production engineering and acoustic emission.
