  1. 1. Space Utilization in Road Transportation: A Case Study of Truck Deliveries

    University essay from Göteborgs universitet/Graduate School

    Author : Marija Nikolova; Sirious Nterai; [2023-07-03]
    Keywords : Distribution; Emissions; Packaging; Truck deliveries; Space Utilization; Space Optimization;

    Abstract : Aim: To understand why big logistics companies do not focus their resources on improving space utilization and decreasing the phenomenon of empty running. Moreover, this study aims to present the potential economic and environmental benefits of reduced excess air in packaging and its effect on truck deliveries. READ MORE

  3. 2. A hashing algorithm based on a one-way function in the symmetric group Sn

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Adrian Perez Keilty; [2022]
    Keywords : cryptography; hashing; symmetric group; one way function;

    Abstract : We have found an operation between permutations in the symmetric group Sn upon which we have experimentally derived results that can be linked to desirable properties in cryptography, mainly in the domain of one-way functions. From it, we have implemented a beta version of an algorithm for a hashing function by exploiting the operation’s low computational cost for speed and its properties for security. READ MORE

  4. 3. Evaluation of DC Fault Current in Grid Connected Converters in HVDC Stations

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Soham SinhaRoy; [2022]
    Keywords : Symmetrical monopole; HVDC LCC and VSC; CTL; MMC; Converter reactor; DC smoothing reactor; DC pole-to-pole fault; Peak factor; SCC; SCR; PSCAD EMTDC;

    Abstract : The main circuit equipment in an HVDC station must be rated for continuous operation as well as for stresses during ground faults and other short circuits. The component impedances are thus selected for proper operation during both continuous operation and short circuit events. READ MORE

  5. 4. Strategic passenger-oriented timetable design : Long-term timetable designs with minimised passenger inconvenience

    University essay from KTH/Transportplanering

    Author : Yari de Graaf; [2021]
    Keywords : ;

    Abstract : Timetable development and design is a complex process that is crucial for safe and efficient railway operations. The combination of steel wheels and steel rails makes it possible to create trains and to transport many vehicles, thus passengers and freight, at the same time, but it also results in longer braking distances.

  6. 5. Client controlled, secure endpointto-endpoint storage in the cloud

    University essay from KTH/Hälsoinformatik och logistik

    Author : Maximilian Michelson; [2020]
    Keywords : ;

    Abstract : Abstract Softronic's customers do not want them to store sensitive data in a cloud environment as theydistrust the cloud providers with keeping sensitive data secret and are afraid of violating GDPR.Softronic wants to prove that data can be kept protected using encryption, even though it is storedin a cloud, and the goal of this thesis is to find a cryptographic solution with good security and performance.
