Evaluation of innovation : Creation of a framework to assess the potential forgrowth of visionary innovations in the Swedish IT sector / Utvärdering av innovation : Skapande av ett ramverk för att utvärdera potentialen förtillväxt av visionär innovation inom den svenska IT sektorn

JOHANNISSON, CARL January 2015 (has links)
<p>Over the course of history, innovation has been the forefront of industrial change. New innovations have continuously surpassed old solutions, which have contributed to the trajectory of mankind. In today’s market IT has an increasingly important role. Innovation within IT is characterised by high degrees of visionary thinking and optimism towards the success of the venture. This has contributed to bubble effects emerging in the economy of a highly speculative nature.</p><p>A central issue lies in the complexity of evaluating innovation and especially more radical and visionary ones. In general terms of evaluation, innovations are evaluated in two main phases: internally and externally. For visionary innovations it is not evident how and on what grounds the innovation should be evaluated both internally in terms of feasibility and externally in terms of market response. In that aspect there is a gap in evaluation and especially <em>how </em>visionary innovation can be evaluated. The aim of the research is to investigate the phenomenon of visionary innovation and contribute with knowledge about the characteristics that influence growth and adoption.</p><p>The research is based upon a two-step qualitative investigation. Firstly the research is imed at constructing a framework for evaluating the innovation and thereafter objectifying the characteristics on case studies within the IT sector.</p><p>The research has found three major areas for evaluation: (1) <em>the eco-system, </em>(2) <em>the  ustomer </em><em>behaviour </em>and (3) <em>the target market</em>. The eco-system is focused towards the ompetitive environment, the technology and the infrastructure. The customer behaviour  ddresses customers’ existing behaviours, their needs and demands and the surplus value  he new offering brings. In terms of the customer behaviour the switching costs and benefits  of other alternatives is also important to consider. Finally, the target market  onsists of the market characteristics, the customer segmentation and the overall  ttractiveness of the market. Based on the characteristics of these factors and the market  nd industry, constraints and drivers can be identified to either support or contradicts the  peed of adoption of new solutions.</p><p>The main findings of the report are that growth is dependent on and influenced by positive and negative drivers. The three elements the drivers are thus connected and correlating, in the sense that the drivers can have different levels of severity. For instance, a negative driver that is negatively correlated with another element has a high level of severity related to growth.</p>

Considerations and Novel Technologies in Industrial Water Treatment - Treatment of challenging wastewater / Rening av industriella avloppsvatten - nyckelfaktorer och nya tekniker

Toll, Nils January 2021 (has links)
Industriell vattenrening är ett extremt viktigt område inom Miljöskyddsteknik då 60% av allt sötvatten inom Sverige används av industrier. Substanser som PFAS, aromatiska textilfärger, fenol och läkemedelsrester är extra utmanande då dessa kan vara gifta för biologisk rening. Syftet med denna rapport var att först redogöra några av de viktigaste avvägningarna som behöver göras när ett industriellt vattenreningsverk designas. I del två av arbetet har en kartläggning av teknologier som kan användas för att assistera eller ersätta biologisk rening. Det existerar flera olika typer av tekniker för att ersätta biologisk rening, men majoriteten av dessa konsumerar stora mängder värme eller elektricitet, vilket kan leda till stora rörliga kostnader. En trend inom industriell vattenrening är elektrifiering. Elektrifiering ger möjlighet att återvinna kemikalier, selektiv separation av joner, automatisk justering av pH via tekniker som elektrodialys och elektrokoagulering. Kall plasmaoxidation och kavitation kan även användas för destruktion av organiska ämnen. I takt med att förnyelsebar energi blir billigare att producera och om regeringen inför el-subventioner för industrin så kommer användbarheten av dessa tekniker att öka. Membranprocesser kan användas för att intensifiera processer som extraktion och indunstning. Med hjälp av membran kan separationshastigheten och energianvändningen minskas. Enzym kan användas för att skräddarsy rening för att bryta ner specifika ämnen vid låga tryck och temperaturer. Skumseparation är en mycket lovande process som kan användas för separation av ytaktiva ämnen som PFAS och har en mycket enkel design och låga energikostnader. / Industrial water treatment is an important field of study as industries in Sweden consumes over 60% of the available freshwater. Furthermore, only 60% of the industrial wastewater in Europe receive treatment before its discharged. Hard to oxidize compounds such as dyes, phenol, and PFAS are a major problem within the field as they often exhibit toxic or inhibiting qualities towards biological treatment methods. Therefore, the purpose of this thesis is twofold; firstly, some of the most important considerations when designing an industrial wastewater treatment plant is discussed to aid someone new to the field. Secondly, novel technologies that could be used to support or replace biological treatment methods are discussed. There exist several different novel technologies that can be used to treat organic pollutants. However, many of these techniques are very energy intensive, leading to high operational costs. A major trend within wastewater treatment is the electrification of treatment techniques. These enables the recycling of chemicals, selective removal of ions and automatic neutralization of pH by means of electrodialysis and electrocoagulation. They can also be used for destruction of organics using cavitation or cold plasma oxidation. The usefulness of these techniques is likely to increase in the future as the electrification of industry picks up speed and subsidies on industrial electricity prices are put in place. Membrane processes can intensify already existing unit operations such as evaporation and extraction. By employing a membrane, the speed of separation and the energy use can be lowered. Enzymatic treatment can be used to degrade several different compounds at low temperatures and pressures by tailoring the mix of enzymes to perfectly fit the wastewater in question. Foam separation is also interesting technology in the removal of surface-active chemicals and compounds due to its simplistic design and low operational cost. The use of this technology is likely to increase in the future if the legislation regarding persistent organics is tightened further.
