This paper proposes a substrate integrated waveguide (SIW) slot antenna array for wideband gigabyte mobile radio application in E-band. The wideband unit cell design is based on simultaneous feeding of 4-element radiation slots with a higher order cavity mode directly excited by a simple slot aperture fed by a microstrip fork-like tuning stub. Employing the higher order mode along with the slot ap
There is a significant infrastructure in the world for using liquefiedpetroleum gas (LPG). The fuel is used in many applications, spanningfrom heating to chemical processes as well as a vehicle fuel. To be able touse this infrastructure also after a transition from fossil to renewablesources, a technology for producing LPG from such resources (glycerol,cellulose etc.) is being developed. This repo
Denna litteraturstudie är en del av projektet ”Smart tillgänglighet i bytespunkter” som är ett gemensamt forskningsprojekt mellan K2 och Mistra SAMS. Studien syftar till att få en bild av vilken forskning som finns angående bytespunkters planering och om det redan finns forskning som kopplar ihop bytespunkter och mobilitetstjänster. Vidare är ett undersyfte att ta reda på vad som är viktigt ur ett
Having a positive impact on other people's lives typically increases the likelihood of regarding one's work as meaningful. In some settings, however, employees have little or no contact to those who experience the impact of their work. Our paper examines how such distance affects these employees' construction of their work as meaningful. We present the findings of an in-depth case study of medical
Stakeholder interaction is important for enabling environmental research to support the societal transition to sustainability. We argue that it is crucial to take researchers’ approaches to and perceptions of stakeholder interaction into account, to enable more clarity in discussions about interaction, as well as more systematic interaction approaches. Through a survey and focus group interviews w
Background People with mobility disability (MD) or obesity often have more health problems and are less able to participate in work than individuals without these conditions. This study investigated whether people burdened with MD and obesity have a greater risk of unemployment than people with either one (MD only or obesity only) or none of these conditions. Methods The study included two Swedish
This study presents a pre-registered replication of one of the most influential articles in the customer engagement literature entitled Consumer Brand Engagement in Social Media: Conceptualization, Scale Development and Validation (Hollebeek, Glynn, & Brodie, 2014, Journal of Interactive Marketing, 28[2], 149–165). By employing the popular social media brand Instagram®, which is often used by
Human stem cells have the potential to transform medicine. However, hurdles remain to ensure that manufacturing processes produce safe and effective products. A thorough understanding of the biological processes occurring during manufacture is fundamental to assuring these qualities and thus, their acceptability to regulators and clinicians. Leaders in both human pluripotent and somatic stem cells
Klineterna vänder sig knappast till sina advokater för att få veta vad de inte får göra, utan för att få klart för sig hur de ska göra det de vill göra. I en tid när allt fler och allt starkare mänskliga viljor gör sig gällande för att främja utvecklingen av hållbara samhällen, kan den förutseende advokaten stärka sin roll som klientens bästa rådgivare. Till de instrument som står advokaterna till
In his excellent book Normvetenskap (Norm Science), has initiated an interesting discussion on strategic normative thinking (SNT). This article presents a case study trying to verify, falsify or, if possible, shed light upon aspects upon SNT. The unit of analysis for the study is the concept of norms and the operational set of measures relates to research on norms. The analysis of the case show´s
Lera består utav små finkorniga lermineraler, vilka utgörs till stor del av elektrostatiskt laddade nanopartiklar, även kallade lerplattor. En lerplatta har en tjocklek på en miljarddels meter och dess diameter kan variera alltifrån fem till tusen gånger större än tjockleken, vilket kan jämföras med ett A4-ark, där kortsidan är tusen gånger större än tjockleken. Denna storleksskillnad ger upphov tClay minerals consist of anisotropic nanoplatelets where the majority of the clay minerals are highly charged, and thus, swell in aqueous solution. The structure and swelling depend on the type of clay mineral, and also on the ionic composition, and temperature. The natural clay mineral montmorillonite have been studied both theoretically and experimentally. Theoretically, coarse-grained models ha
Efter en landreform, som genomfördes i slutet av 40- och i början av 50-talet, blev de flesta taiwanesiska bönderna hemmansägare och odlade marken på små lantegendomar. Denna efterkrigsreform banade väg för en ekonomisk utveckling som väsentligt påverkade och förändrade bondesamhället. När det taiwanesiska jordbruket visade tecken på stagnation på 1970-talet, förändrades böndernas syn på markinnehAfter post-war land reform that took place between 1949 and 1953, most Taiwanese farmers became owner-cultivators working on small landholdings. Post-war land reform paved the foundation for economic development and industrialization, processes that squeezed the agricultural sector and created changes in farming villages. When Taiwanese agriculture showed signs of stagnation in the 1970s, farmers’
The optimal spectral efficiency of MIMO antennas in Rayleigh and ideal channels are investigated when bandwidth requirements are placed on the antenna. By posing the problem as a convex optimization problem restricted by the port Q-factor a semi-analytical expression is formed for its solution. The antennas are simulated by method of moments and the solution is formulated both for structures fed b
The purpose of this paper is to address the perceptions senior public leaders in local government have regarding the need for business intelligence and their perceptions of the extent to which their organizations are capable of effectively assimilating business intelligence.The data are from a survey on local governments’ need for and capabilityto use business intelligence, with a response rate of
In this paper, we investigate the problem of finding housing for refugees once they have been granted asylum. In particular, we demonstrate that market design can play an important role in a partial solution to the problem. More specifically, we investigate a specific matching system, and we propose an easy‐to‐implement mechanism that finds an efficient, stable, and maximum matching. Such a matchi
