  1. 1. Scann Loss Reduction on Phased Array Antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Wanyu Zhang; [2022]
    Keywords : Phased Array Antenna; Vivaldi Antenna; Scan Loss; Coverage Angle; Sub-array; Embedded Radiation Pattern; Fasad Array Antenn; Vivaldi Antenn; Skanningsförlust; Täckningsvinkel; Sub-array; Inbyggt strålmönster;

    Abstract : Phased array antennas with small size and light weight are proposed to make signal transmitting more efficiently and accurately. These antennas have such advantages that they can realize beam scanning over a large range, accurately track and identify targets within the observation range. READ MORE

  3. 2. Structural basis of modulation by pH and calcium in a ligand-gated ion channel

    University essay from KTH/Genteknologi

    Author : Olivia Andén; [2021]
    Keywords : Pentameric ligand-gated ion channels; bacterial homolog; protein expression; protein purification; cryo-electron microscopy; data processing; protein structure; Pentamerisk ligandstyrd jonkanal; bakteriell homolog; proteinexpression; proteinrening; kryo-elektronmikroskopi;

    Abstract : Pentameriska ligandstyrda jonkanaler (pLGICs) är avgörande för omvandlingen av kemisk till elektrisk signalöverföring i djurs nervsystem. Dysfunktion i dessa kanaler har visat sig vara kopplad till flera sjukdomar inklusive epilepsi, schizofreni, Alzheimers och autism, vilket gör dem till en måltavla för en mängd olika läkemedel.

  4. 3. Hand Gesture Controlled Omnidirectional Vehicle

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : ANTON NORMELIUS; KARL BECKMAN; [2020]
    Keywords : Mechatronics; Mecanum Wheels; Hand Gesture Control; Arduino; Wireless; Mekatronik; Mecanumhjul; Handstyrning; Arduino; Trådlös;

    Abstract : The purpose of this project was to study how hand gesture control can be implemented on a vehicle that utilizes mecanum wheels in order to move in all directions. Furthermore, it was investigated how the steering of such a vehicle can be made wireless to increase mobility. A prototype vehicle consisting of four mecanum wheels was constructed. READ MORE

  5. 4. Development of a Concealed Power and Signal Transfer System for Sliding Doors

    University essay from Lunds universitet/Innovation

    Author : Max Koskinen; Jakob Alvelid; [2019]
    Keywords : Product development; Sliding doors; Power transfer; Signal transfer; Spiral cable; Rapid prototyping; Technology and Engineering;

    Abstract : This master’s thesis report describes the product development process of a durable and concealed product for transferring power and signals to the moving door leafs of sliding doors. The thesis has been conducted in collaboration with Assa Abloy Entrance Systems, with the goal of enabling the use of accessories such as privacy e-glass, screens integrated in the glass, electric locks and sensors mounted on the door leafs for their sliding doors.

  6. 5. COOPERATIVE COMMUNICATION TECHNIQUES IN WIRELESS NETWORKS (ANALYSIS WITH VARIABLE RELAY POSITIONING)

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Danna Nigatu Mitiku; Onwuli Chinedu Lawrence; [2010]
    Keywords : Amplify-and-Forward; Bit-Error-Rate; Cooperative Communications; Decode and Forward; Performance Analysis; Signal-to-Noise-Ratio; Wireless Networks;

    Abstract : Signal transmission in Wireless Networks suffers considerably from many impairments, one of which is channel fading due to multipath propagation. Cooperative communication is a technique which could be employed to mitigate the effects of channel fading by exploiting diversity gain achieved via cooperation between nodes and relays. READ MORE
