  1. 1. Towards a Concurrent Multidisciplinary Design Optimization of Mechatronic Systems

    Författare :Fariba Rahimi; Martin Grimheden; Johan Ölvander; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Sammanfattning : Multidisciplinary design optimization of mechatronic systems is a cumbersome task that considers integration of several engineering domains simultaneously. Hence, a holistic method should treat these engineering domains concurrently in the development phase and result in a solution for the system that is optimum considering several disciplines. LÄS MER

  2. 2. Adhesion and Friction - a Study on Tactility

    Författare :Kenneth Duvefelt; Ulf Olofsson; Emile Van Der Heide; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Adhesion; finger; friction; humidity; material; model; tactile friction; tactility; Machine Design; Maskinkonstruktion;

    Sammanfattning : Although we are surrounded by hundreds of surfaces we can still distinguish them from each other simply by touch. The tactile information, interpreted by our brain and given by our fingers, is precise, but to put words to the sensation is very difficult — is it smooth, sticky or harsh? We do not only perceive surfaces differently, we also describe them in our own way. LÄS MER

  3. 3. A Comparative Investigation of Gear Performance BetweenWrought and Sintered Powder Metallurgical Steel : Utilizing In-situ Surface Profile Measurements to Investigate theInitiation and Evolution of Micropitting and Pitting Damage

    Författare :Edwin Bergstedt; Ulf Olofsson; Bengt-Göran Rosén; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gear testing; Micropitting; Pitting; Efficiency; Surface transformation; Kugghjulstestning; Micropitting; Pitting; Effektivitetsmätning; Yttransformationer; Machine Design; Maskinkonstruktion;

    Sammanfattning : Vehicle electrification is a strong trend that introduces new challenges, such as increased input speed of the transmission and increased power density. Alsothe noise emittance of the gearbox is of increasing importance, as the sound of the gearbox is no longer masked by the internal combustion engine. LÄS MER

  4. 4. Mobile Network Operator Collaboration using Deep Reinforcement Learning

    Författare :Athanasios Karapantelakis; Elena Fersman; Crnkovic Ivica; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Machine Design; Maskinkonstruktion;

    Sammanfattning : Fifth Generation Mobile Networks (5G) are designed to offer connectivity services for new types of applications that not only address the needs of private individuals, but also those of enterprise customers. Network requirements of such applications often transcend the capabilities of a single Mobile Network Operator (MNO). LÄS MER

  5. 5. A Position Control-based Approach to Stiff Objects Haptic Rendering

    Författare :Yang Wang; Kjell Andersson; Lei Feng; Anders Robertsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; haptic rendering; position control-based approach; rigid-body interaction; Machine Design; Maskinkonstruktion;

    Sammanfattning : With electronic components and computational power becoming more portable and available to general consumers, applications like virtual reality (VR) and mixed reality (MR) are on the rise and renovating the industry of training simulators. Though it is not fully accepted in surgical robots, haptic force feedback can be safely introduced into various surgical training simulators to convey the necessary haptic cues needed to develop hand-eye coordination and motor skills.
