1. 1. Optimal placement of a Mobile Stroke Unit (MSU) to achieve improved stroke care

   University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

   Author : Oliver Dahllöf; Oliver Dahllöf; Felix Hofwimmer; Felix Hofwimmer; [2018]
   Keywords : mobile stroke unit; mobile stroke unit; MSU; MSU; stroke treatment; stroke treatment; stroke; stroke; door-to-needle; door-to-needle; DTN; DTN; thrombolysis; thrombolysis; placement; placement; location; location;

   Abstract : Tid till behandling är livsviktigt för människor som får en stroke. På olika platser i världen har man därför sett värdet i att införskaffa en specialambulans för stroke (stroke-ambulans) som har specialutrustning och specialpersonal som kan utföra intravenös behandling (trombolys).

3. 2. Higher temperatures increase nutrient availability in the High Arctic, causing elevated competitive pressure and a decline in Papaver radicatum

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Hanna Modin; [2016]
   Keywords : Papaver radicatum; High Arctic; soil conditions; Zackenberg; Greenland; climate change; global warming; Arctic vegetation; Arctic plant; Arctic Poppy; active layer depth; soil moisture; competitive pressure; Earth and Environmental Sciences;

   Abstract : Linking changes in the vegetation cover with factors that can moderate the effects of climate change is central to our understanding of Arctic ecosystems and their susceptibility to change. The aim of this study has been to investigate the moderating effects of soil conditions. READ MORE

4. 3. Network Monitoring in Delay Tolerant Network

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Alexej Ismailov; [2015]
   Keywords : DTN; Delay Tolerant Network; Disruption tolerant network; Prophet; Epidemic routing; The ONE; DTN simulation; network monitoring; tactical network; movement model; markov; delay estimation;

   Abstract : A Disruption Tolerant Network (DTN) is a sparse network where connectivity is regulated by the proximity of mobile nodes. Connections are sporadic and the delivery rate is closely related to node movement. READ MORE

5. 4. Assessing the Vulnerability of DTN Data Relaying Schemes to Node Selfishness

   University essay from Institutionen för informationsteknologi

   Author : Shyam Sundar Balasubramanian; [2012]
   Keywords : DTN; selfish nodes; ONE simulator;

   Abstract : The main principle behind the working of delay tolerant networks (DTN) is the mobility of the nodes along with their contact sequences for exchanging data. Nodes which are a part of the DTN network can behave selfishly due to network reservation policy, especially when constrained to energy or storage space. READ MORE

6. 5. Implementation of a Delay-Tolerant RoutingProtocol in the Network Simulator NS-3

   University essay from Institutionen för datavetenskap

   Author : Fredrik Herbertsson; [2010]
   Keywords : Delay-tolerant network; DTN; routing protocol; ORWAR; network simulator; NS-3;

   Abstract : Small mobile devices with networking capabilities are becoming more and more readily available and used. These devices can be used to form mobile ad hoc networks to communicate, where no infrastructure for network communication exist or where it has been destroyed or is overloaded e.g. in a natural disaster such as a hurricane.
