   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro-electromechanical systems MEMS ; Nano-electromechanical systems NEMS ; heterogeneous 3D integration; Graphene; single-layer graphene; double-layer graphene; bilayer graphene; chemical vapor deposition CVD ; suspended graphene beams; suspended graphene membranes; doubly clamped; fully clamped; silicon on insulator SOI ; vapor hydrofluoric acid VHF ; Young’s modulus; built-in stress; built-in tension; piezoresistivity; gauge factor; accelerometer; resonators; electromechanical sensing; advanced transducers; humidity; gas sensing; sensitivity; CO2 sensing; graphene grain boundary; line defects; optical microscopy; wire bonding; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : This thesis presents a novel approach to integrate chemical vapor deposition (CVD) graphene into silicon micro- and nanoelectromechanical systems (MEMS/NEMS) to fabricate different graphene based MEMS/NEMS structures and explore mechanical properties of graphene as well as their applications such as acceleration sensing, humidity sensing and CO2 sensing. The thesis also presents a novel method of characterization of CVD graphene grain boundary based defects. LÄS MER

3. 2. Studies in the Transformation of Post-Soviet Cities : Case Studies from Kazakhstan

   Författare :Michael Gentile; Jan Öhman; Örjan Sjöberg; Thomas Lundén; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Kazakhstan; former Soviet Union; urbanisation; survey method; post-Soviet cities; residential preferences; socio-spatial differentiation; Kulturgeografi; Human geography; Kulturgeografi;

   Sammanfattning : Since the demise of central planning, post-Soviet cities have found themselves operating in a radically different economic climate. Contrary to the situation during the Soviet époque, market relations and the urban economy's adjustment thereto constitute the reality which urbanites face in their daily lives. LÄS MER

4. 3. The Hypertemple in Mind : Experiencing Temple Space in Ezekiel, The Temple Scroll and Mishnah Middot

   Författare :Natalie Lantz; Göran Eidevall; Cecilia Wassén; Molly Zahn; Uppsala universitet; []
   Nyckelord :critical spatial theory; divine presence; Ezekiel 40-48; hypertextuality; immersion; interaction; temple descriptions; The Temple Scroll; Mishnah Middot; media technology; virtual reality; Biblical Exegesis; Bibelvetenskap;

   Sammanfattning : In this study I perform a theory driven close reading of selected sections of Ezekiel (chs. 40-48), the Temple Scroll (cols. 2/3-13:8, 29:3b-47:18) and Mishnah Middot, in order to explore how the architectonic descriptions of the temple in these works may have been used to create temple space in the minds of their immediate audiences.

5. 4. Residual Stress Distributions in Additively Manufactured Parts : Effect of Build Orientation

   Författare :Prabhat Pant; Ru Lin Peng; Johan Moverare; Kjell Simonsson; Jonathan Almer; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM;

   Sammanfattning : Additive manufacturing (AM) of parts using a layer by layer approach has seen a rapid increase in application for production of net shape or near-net shape complex parts, especially in the field of aerospace, automotive, etc. Due to the superiority of manufacturing complex shapes with ease in comparison to the conventional methods, interest in these kinds of processes has increased.

7. 5. Towards a Minor Urbanism : Thinking Community without Unity in Recent Makings of Public Space

   Författare :Ida Sandström; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :HUMANIORA; HUMANITIES; Public Space; Spaces of Being-in-Common; Spaces of Collective Care; Minor Urbanism; Community without Unity; Community; Urban design; Urban space; City park; Urban planning; Co-Production; Urban Participation; Urbanism; Difference; Spaces of difference; Diversity; Spaces of diversity; offentliga rum; offentliga platser; urban arkitektur; Planering; mångfald; torg och parker; Urban design; urban gemenskap; urbanism; medborgardeltagande; medborgarengagemang; planeringspraktiker; gestaltad livsmiljö;

   Sammanfattning : HOW CAN WE PLAN AND DESIGN FOR community in diverse urban situations? In response to segregation and social fragmentation, public space is increasingly being conceived of as a vehicle for fostering openness towards differences, both in planning practice and theory. Drawing on two recent public space projects – Superkilen in Copenhagen, Denmark, and Jubileumsparken in Gothenburg, Sweden – this thesis explores what this hopeful idea may mean in terms of the actual making of public space.
