Smart city is a phenomenon here to stay, constantly evolving and expanding and is fast becoming a paradigm for the transformation of connected cities. More and more parts of cities are being connected and with it, the risks and issues are on the rise. However, smart city projects often overlook the pervasive cyber security risks and threats that permeates these initiatives. The endeavour of this r
The technical department usually own the Business Intelligence and Analytics (BI&A) systems. However, due to the need for faster decision-making, the business users started to demand using BI&A in their daily work as well. The traditional training for BI&I focused more on the technical people, who have proficient technical background while the business users lack technical backgrounds.
The increasing globalization of innovation activities has generated “globally organized web of complex interactions” for innovation, which are called global innovation networks (GINs). The current study on GINs has extended our understanding of network participants to the small and medium-sized enterprises (SMEs) from emerging economy, and enlightened us on the drivers behind the participation of
The real space behavior of the GW self-energy in the electron gas model was investigated in this thesis work. The self-energy is naturally decomposed into the screened-exchange and the Coulomb-hole components. The self-energy calculated with different electron densities as function of frequency and position was compared with the static approximation. At low frequency, the screened-exchange self-en
Eutrofiering är ett världsomspännande problem för sötvatten. Höga tillflöden av fosfor leder till försämrade förutsättningar för många typer av rovfiskar såsom abborre (Perca fluviatilis) och gädda (Esox lucius). Biomanipulation är en åtgärd som antas förbättra förutsättningarna för dessa rovfiskar, men kan samtidigt betyda försämrade förutsättningar för rovfiskarter som får konkurrensfördel av lå
Disaster risk management efforts currently focus on long-term preventive measures and post-disaster response. Outside of these, there are many short-term actions, such as evacuation or distribution of water purifications tablets, medical supplies or flood response drills, which can be implemented in the period of time between the warning and a potential disaster to reduce the risk of impacts.

IS analysis and design processes rely on models for communicating requirements between business and IS professionals. Modelling standards are universally recognisable notations/languages for constructing these models. An emerging approach is to capture business decisions intended for decision automation in models. The Object Management Group has recently released a standard for this purpose, the D
Malware has proven to be a persistent problem with an increasing amount of variations, and new attack vectors are constantly being taken advantage of. Security specialists are always on the hunt for new technologies useful in the fight against malware. Blockchain technologies bring promises of high integrity, decentralization, and transparency. The technology is very much in its infancy, but previ
Syftet med denna studie är att undersöka hur dagens kosacker i Ryssland minns den 24 januari, dagen tillägnad minnet av de kosacker som dödades av bolsjevikerna under och i efterdyningarna av det ryska inbördeskriget. Studien är en diskursanalys av 5 olika artiklar som behandlar dagen. Genom diskursanalys och teorier om kollektivt minne påträffades två olika identiteter i materialet, varav den en
Data quantities and their sources have amplified over the years and so has the trend to employ dashboard-based data visualizations into the hands of a wider audience of end-users. By selecting four of the most common data visualization formats and combining these into a dashboard this thesis quantitively explored the relationship between similarity features of dashboard-based data visualizations,
The main purpose of any Customer Relationship Management(CRM) system of any customer-focused organization is to build new and retain old relationships with its customers.Such CRM systems provide customer data so that its users or top management can make correct decisions in order to improve organization’s performance. Nowadays, advanced analytics in the form of Business Intelligence (BI) can be us
Oils are some of the most energy dense compounds produced in nature and play a vital role in society as a source of food, energy and as raw material in many chemical processes. Plant produced oils (triacylglycerols) are a key asset in the transition away from fossil oils. The progress made in recent years in molecular biology has greatly increased our understanding of plant oils biosynthesis. Howe
Klimatet på jorden ändras hela tiden och temat klimatförändringar är mer aktuellt än någonsin. För att förstå vilka konsekvenser klimatförändringarna har är det viktigt att förstå hur klimatet påverkades förr av uppvärmning eller avkylning. För att utröna detta används olika proxymetoder. Under senare år har man insett att Mg/Ca kvoten i skalen hos bentiska foraminiferer är en användbar proxymetodThe climate on earth is continuously changing, and climate change discussions are more relevant than ever. To understand the consequences of climate change one has to understand how the climate responded to changes in temperature in the past. Different proxy methods can be used to determine these changes. During later years, researchers have discovered that the Mg/Ca ratio in benthic foraminifera
The aim of this thesis was to investigate how social counsellors employed in health care reasoned on transgender persons as a group and their work with transgender persons, as well as analyse the knowledge they use in that work. The method used for collecting data was qualitative interviews with social counsellors working in health care. Social counsellors interviewed were selected by way of conve
VIX indexet, även kallat "the fear gauge" är världens ledande indikator för framtida volatilitet. Indexet beräknar ett 30 dagars framtida förväntat värde på volatiliteten kring USA’s börs S&P500. Indexet baseras på köp och säljoptioner med S&P500 indexet som underliggande tillgång. Optionerna som används in- nehar två olika löptider som vi kallar för nära och nästa periods-optionThe purpose of this paper is through an empirical approach understand the dynamics of VIX and investigate to what degree the benchmark computed by CBOE is representative of its definition. The method implemented is of a design where one constructs a hypothetical world in which synthetic options data are produced by the Bates-Heston model. This implies an underlying and known volatility with chosen
The effects on trade from negotiating and entering voluntary partnership agreement is estimated using forest product trade data from 2000 to 2014 on countries in the Forest Law Enforcement, Governance and Trade (FLEGT) licensing process. Gravity model framework is used and the result shows that beginning negotiations lead to an export drop by approximately 0.6 percent and is relatively stable the
In this thesis, I examine the relation between size and performance in Swedish equity mutual funds during the period 2010 – 2017. The thesis is divided into two main parts with the first part investigating the relation between size and performance by dividing the sample of 107 mutual funds into three groups according to the size of the funds. The funds are then analyzed with three different perfor
