The behavior of a firm to engage in international innovation collaborations is characterized by complex relations that are identified at more than one level. However, less has been done to understand multilevel interactions and the effects of the national framework conditions. In this respect, this study elaborates a comprehensive set of country and firm-level variables, including the properties o

Som de flesta av oss vet så kretsar planeter i elliptiska banor runt stjärnor. Vissa planeter som ligger väldigt nära de stjärnor som de kretsar får uppleva visa effekter som inte märkbart påverkar de planeterna i omloppsbana längre bort. Dessa effekter uppkommer ur så kallade tidvattenskrafter som härstammar från det faktum att gravitationskrafter beror väldigt mycket på avstånd mellan objekt. DePlanets that orbit their host star closely experience tidal forces due to the strength of gravity not being uniform all over the planet. This leads to effects such as tidal spin synchronization, tidal eccentricity damping and tidal semi-major axis damping. This project aims to study how the time scales for these phenomena are affected by the planetary parameters such as mass, radius and the tidal

Vertical heterostructures between graphene (Gr) and hexagonal boron nitride (hBN) have attracted a great deal of interest, due to their potential applications in the semiconductor industry as new and superior transistor materials. The direct growth of the heterostucture still remains challenging and in this bachelor thesis, I report a novel electron assisted growth technique, which is used to atte

The route towards linearly fused heptakis-Tröger’s base was followed using a 12 step synthesis route. Hope remains that the final compound will be purified to a satisfactory level within the near future. Additionally, characterizations of reaction intermediates has been completed, up to monoprotected tris-Tröger’s base which has been submitted for its final characterizations. A specifically design

Rostfritt duplexstål är ett konstruktionsmaterial som skulle kunna tänkas vara konkurrenskraftigt i förhållande till konventionella material inom brobyggnad med tanke på dess höga hållfasthet, marginella underhållsbehov och möjlighet till återvinning. Hittills har det dock inte använts i någon större utsträckning inom brobyggnad framför allt på grund av dess högre kostnad i förhållande till traditDuplex stainless steel is a construction material that could possibly prove competitive in relation to conventional materials in bridge design, given its high strength, marginal maintenance needs and the possibility of recycling. To date, however, it has not been used to any great extent in bridge constructions, mainly because of its higher cost in relation to traditional carbon steel. In this stu

In this thesis, the functionality of existing Crazyflie models is extended to include current implementations of attitude and velocity control. The models are validated both as individual agents and as a swarm through comparisons of swarm behaviour during step, ramp and frequency response testing. The models are found to accurately replicate the dynamics of the real system, but additional research

Recent developments in smart manufacturing enable convergence between the digital and physical worlds of modern manufacturing facilities. This evolution is, however, far from trivial and thorough research and investigation needs to be conducted regarding dynamic connectivity of assets and implementation of data driven analytics, which provides deeper insight into the operational processes.

Resource Based View (RBV) beskriver processer där företag utvecklar konkurrensfördelar som är hållbara över tid. Argument lyfts fram inom RBV som kopplar företagsekonomiska tillväxt och ökade marknadsandelar till hållbara konkurrensfördelar. För att kunna påvisa hållbara konkurrensfördelar förutsätts att tidsaspekten tas i beaktande. Företag bedriver FoU-verksamhet för att förbättra sitt erbjudaResource Based View (RBV) describes processes where companies develop competitive advantages that are sustainable over time. Arguments within RBV links company’s growth and increased market shares to sustained competitive advantages. In order to prove sustained competitive advantages, it is necessary to take the time factor into consideration. Companies innovate to improve their offer. The expec

I takt med det ökade mediala fokus på globalisering och klimathot ställs nya krav på samhället och på att företag ska ta ett moraliskt ansvar för hållbarhetsfrågor. Frågan är om hållbart företagande kan anses förenligt med gällande rätt. Vinstsyftet i 3 kap. 3 § ABL är det grundläggande kriteriet för bolagsledningens beslutsfattande och innebär indirekt att ledningen inte får prioritera till exemThe increased media focus on globalization and climate change has brought new demands from society, which has led to more companies taking moral responsibility for sustainability issues. The question is whether sustainable business can be considered compatible with applicable law. The profit objective in Chapter 3 § 3 in the Swedish Companies Act (”Aktiebolagslagen” [2005:551], ”ABL”) is the fun

I dagens digitaliserade samhälle möter utgivare och publicister av traditionellt tryckt media stora ekonomiska motgångar vid försäljningen av exempelvis nyhetstidningar eller andra tidskrifter. Således har majoriteten av utläggare idag gjort sina publikationer tillgängliga för läsare online. De digitala intäkterna lyckas dock inte väga upp för de förluster utgivarna lider av den nedåtgående försälIn today's digitized society, publishers of legacy printed media face major financial hardships in the sale of newspapers and other magazines. Thus, most publishers today have made their publications available to readers online. However, digital revenues do not make up for the losses that the publishers suffer from the decreasing sales of printed media. This can in part be attributed to the fa

Tredjepartsbesiktning innebär att blivande eller befintliga affärspartners undersöks i syfte att säkerställa att verksamhetsutövarens verksamhetsled utgör en låg risk för korruption, vilket i vissa länder krävs genom lag. Faktorer som i regel anses som varningsflaggor i riskbedömningen inför en affärstransaktion är till exempel om en affärspartner har dömts för något brott av korruptiv karaktär elThird party due diligence is an investigation of prospective or existing business partners in order to ensure a low risk of corruption. In certain countries such an investigation is required by law. Factors to consider in the risk assessment are for example whether a potential or existing business partner has been convicted of any corruption related crime or is associated with political circles.
