  1. 6. Time Synchronization of TDOA Sensors Using a Local Reference Signal

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Alfred Hult; [2020]
    Keywords : TDOA; synchronization; sensor network; correlation; time-delay estimation; estimation; UAV; GPS; timing signal;

    Abstract : Synchronization of distributed time difference of arrival (TDOA) sensor networks can be performed using reference signals from GPS satellites. This method provides high accuracy, but is vulnerable to jamming, and is not reliable enough to be used in military applications. READ MORE

  3. 7. Availability of Smart Contracts that Rely on External Data

    University essay from Linköpings universitet/Programvara och system

    Author : Tjelvar Guo; Daniel Han Herzegh; [2020]
    Keywords : blockchain; smart contract; oracles;

    Abstract : Smart contracts are digital agreements stored and executed on a blockchain. With smart contracts, multiple parties can enter into an agreement whose correct execution is guaranteed by the underlying blockchain. READ MORE

  4. 8. Delay Analysis in Marshalling Yards : The case study of Malmö

    University essay from KTH/Transportplanering

    Author : Chrysi Kontaxi; [2020]
    Keywords : Delay Analysis; Malmo; Marshalling yard; Railways; Simulation;

    Abstract : The management of terminal yards requires quite complex day-to-day operations when hundreds of trains could be entered and/or exited marshalling yards every day. More specifically, multi-dimensional decisions are necessary to be taken in daily basis for management of operations. READ MORE

  5. 9. The impact on fuel costs when optimizing speed and weight in a single truck transportation system.

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Tim Saxman; [2017]
    Keywords : Speed optimization; weight optimization; transportation system; green vehicle routing; vehicle routing problem; VRP; GVRP;

    Abstract : Traditionally, route planning in the transportation sector has only focused on minimizing the total distance driven when transporting goods or people. This is often done using software tools since planning the optimal route is a complex task that is hard to solve by hand. READ MORE

  6. 10. PERFORMANCE ANALYSIS OF DUTY-CYCLE MAC PROTOCOLS IN WIRELESS SENSOR NETWORKS

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Alfredo Frances Galiana; [2016]
    Keywords : ;

    Abstract : This thesis studies the behavior of the S-MAC protocol in a Wireless Sensor Networks (WSN). The main limitation of the WSN is the lifetime of the battery, because normally it is short and it is not possible to change it all the time. For this reason, the battery consumption and the delay have to be low. READ MORE
