  1. 21. CONSTRUCTION EQUIPMENT FUEL CONSUMPTION DURING IDLING : Characterization using multivariate data analysis at Volvo CE

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Mujtaba Hassani; [2020]
    Nyckelord :Idling condition; environmental effect; diesel fuel; machine learning; multivariate data analysis; partial least square regression; support vector machine regression; principal component analysis; principal component regression; correlation coefficient matrix; artificial neural network; exhaust emission reduction techniques; global warming; emission regulation; CO2 estimation techniques; Gaussian process regression;

    Sammanfattning : Human activities have increased the concentration of CO2 into the atmosphere, thus it has caused global warming. Construction equipment are semi-stationary machines and spend at least 30% of its life time during idling. The majority of the construction equipment is diesel powered and emits toxic emission into the environment. LÄS MER

  3. 22. Dynamic prediction of repair costs in heavy-duty trucks

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Lakshidaa Saigiridharan; [2020]
    Nyckelord :Hurdle Gamma model; Hierarchical hurdle Gamma model; Generalized linear model GLM ; Supervised Machine Learning; feature selection; Akaike Information Criterion AIC ; prediction of repair costs; heavy-duty trucks; truck variants; operational features;

    Sammanfattning : Pricing of repair and maintenance (R&M) contracts is one among the most important processes carried out at Scania. Predictions of repair costs at Scania are carried out using experience-based prediction methods which do not involve statistical methods for the computation of average repair costs for contracts terminated in the recent past.

  5. 24. Development of a demo platform on mobile devices for 2D- and 3D-sound processing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Frans Rosencrantz; [2020]
    Nyckelord :Spatial Audio; Raspberry PI; Microphone Array; Dirac;

    Sammanfattning : This thesis project aims for the development of a demonstration platform on mobile devices for testing and demonstrating algorithms for 2D and 3D spatial sound reproduction. The demo system consists of four omnidirectional microphones in a square planar array, an Octo sound card (from Audio Injector), a Raspberry Pi 3B+ (R-Pi) single-board computer and an inertial measurement unit (IMU) located in the center of the array.

  7. 25. Studying the Relation between Linguistic and Design Quality in RESTful APIs

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Edvin Larsson; Jesper Hägglund; [2020]
    Nyckelord :Design patterns; Design antipatterns; Linguistic patterns; Linguistic antipatterns; RESTful APIs; Uniform Resource Identifiers; Detection;

    Sammanfattning : REST (REpresentational State Transfer) is commonly used for designing APIs. Two main categories of REST API quality have been identified in previous research: linguistic and design quality. Linguistic quality revolves around the design of the URIs. Design quality revolves around the metadata and body in HTTP requests and responses. LÄS MER
