1. 1. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Zhenyu Li; [2023]
   Keywords : mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

   Abstract : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. READ MORE

3. 2. Reconfigurable Intelligent Surfaces : Optimal Positioning and Coverage Improvement

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Noé Bernadas i Busquets; [2023]
   Keywords : 6G; Reconfigurable Intelligent Surfaces; Wireless Communications; Coverage; 6G; omkonfigurerbara intelligenta ytor; trådlös kommunikation; täckning;

   Abstract : Med framväxten av framtida mobilgenerationer bortom 5G, studeras nya teknologier för att tillgodose de förväntade kraven för framtida tjänster som Ultra-Reliable Low Latency Communications (URLLC) eller Virtual Reality. Bland dessa teknologier uppstår Reconfigurable Intelligent Surfaces (RIS) som en av de mest lovande på grund av deras förmåga att förbättra kanalen samtidigt som de bara ökar nätverkets energiförbrukning måttligt.

   Author : Qian Mei; [2023]
   Keywords : ;

   Abstract : Rice is a vital crop and main source of calories for half the global population, particularly in the GlobalSouth. Despite increasing demand for rice, climate change, urbanisation, and land use development arethreatening rice production and therefore food security. READ MORE

6. 5. How Startups Approach Internationalization - A study of the early stage of Swedish healthtech startups and the support from the Regional Science Park

   University essay from Göteborgs universitet/Graduate School

   Author : Shijia Ma; Jonathan Sarge; [2022-07-05]
   Keywords : Startup; Internationalization; Science Park; Networking; Entrepreneur; Regional Innovation System; Healthtech;

   Abstract : In response to a certain gap of lacking research, lacking international implications in the healthtech startups’ pre-internationalization stage, and limited insights into the science parks’ roles when it comes to the startups internationalization. This thesis is aiming to in-depth analyze the multi-elements of a science park as an intermediate support for those startups who choose to be situated at the science park. READ MORE
