  1. 1. A Linear, Wide-band, Low-Power Receiver for Narrowband- Internet of Things (NB-IoT)

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Rohan Raghunath; Ghanashyam Ravindranath Prabhu; [2018]
    Keywords : NB-IoT; FTNC; Harmonic rejection; N-path filtering; RX Front End; Low power; Wide-band; Passive mixer; Current mode; Technology and Engineering;

    Abstract : Advancement of technology with the aid of new application, wireless communication has grown rapidly in the past two decades. Recently, in the wireless communication industry, Narrowband- Internet of Things (NB-IoT) is being discussed by everyone, as the most important emerging technology of the day. READ MORE

  2. 2. Development of Vessel Phantoms for Ultrasound Methods

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Benjamin Meirza; [2018]
    Keywords : Longitudinal movement of the arterial wall; Vasa vasourom; Micro vessles; SEBS; Ultrasound phantom.; Technology and Engineering;

    Abstract : Phantoms mimicking the specific mechanical and acoustic properties of human tissues are essential in the development and evaluation of novel ultrasound methods. In this work, various ultrasound phantoms are proposed to be used in the development of ultrasound methods to investigate the arterial walls longitudinal movements influence on the vasa vasorum circulation.

  3. 3. Enrichment of microparticles in droplets using acoustophoresis

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Klara Björnander Rahimi; [2018]
    Keywords : droplet microfluidics; acoustophoresis;

    Abstract : Acoustophoresis is a label free method where the acoustic radiation force is used to manipulate microparticles inside microfluidic channels. The magnitude of the force is dependent of several parameters, which include the density, speed of sound and size of the microparticles, as well as the amplitude of the pressure waves. READ MORE

  4. 4. Development of a general acoustic model for an arbitrary surveillance camera design

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Shenyang Fei; [2018]
    Keywords : MEMS microphone; Frequency Response; Thermoviscous Losses;

    Abstract : This thesis studies how the mechanical design of a surveillance camera affects the acoustic performance, mainly in terms of the frequency response within the human hearing range. During the project, the mechanical characteristics that affect frequency response were investigated by measuring the camera’s audio behavior in an anechoic chamber. READ MORE

  5. 5. Horizontal natural frequency in a 10 story building : A comparison between CLT and concrete using estimate calculations

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Jennifer Eriksson; [2018]
    Keywords : Horizontal natural frequency; tall timber building; timber structure; CLT; wind induced motion; tall CLT building; Horisontell egenfrekvens; hög träbyggnad; höga trähus; KL-trä; vindinducerade rörelser; högt KL-hus;

    Abstract : Tall slender buildings are easily set in motion by wind and earthquakes but by estimating the buildings horizontal natural frequencies in the design phase, these motions can be kept within acceptable boundaries. There are many parameters that decides the natural frequency of a building and it can therefore be difficult to calculate it. READ MORE
