1. 1. D-band Power Amplifiers in Vertical InGaAs Nanowire MOSFET Technology for 100 Gbps Wireless Communication

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

   Author : Patrik Blomberg; Ludvig Pile; [2022]
   Keywords : D-band; Power Amplifier; Pseudo-differential common source; Stacked; Vertical InGaAs nanowire; MOSFET; Technology and Engineering;

   Abstract : Two different topologies of power amplifiers (PAs) are designed in the frequency range 130-174.8 GHz for use in backhaul transmitters. These are the pseudo-differential common source (PDCS) and the single-ended stacked amplifier topologies. READ MORE

3. 2. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Johannes Jonsson; Anton Andersson; [2021]
   Keywords : Vibratory driving; sheet pile; Technology and Engineering;

   Abstract : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. READ MORE

4. 3. Numerical analysis of vibrations due to impact pile driving

   University essay from Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Sebastian Andersson Olivecrona; Rasmus Sulander; [2016]
   Keywords : Finite element method; Concrete pile; Impact pile driving; Ground vibrations; Soil mechanics; Soil dynamics; COMSOL Multiphysics; Technology and Engineering;

   Abstract : Vibrations originating from constructional work can affect the nearby soil and structures. Depending on the properties of the vibrations, these can result in settlements in the soil and damages to existing structures. Along with blasting, impact pile driving is one of the greatest sources of vibrations on a construction site. READ MORE

5. 4. Soil Plugging of Open-Ended Piles During Impact Driving in Cohesion-less Soil

   University essay from KTH/Jord- och bergmekanik

   Author : Victor Karlowskis; [2014]
   Keywords : soil plugging; impact driving; driving resistance; driving records; jordpluggning; slagdrivning; drivmotstånd; pålprotokoll;

   Abstract : During impact driving of open-ended piles through cohesion-less soil the internal soil column may mobilize enough internal shaft resistance to prevent new soil from entering the pile. This phenomena, referred to as soil plugging, changes the driving characteristics of the open-ended pile to that of a closed-ended, full displacement pile. READ MORE

6. 5. Pile – Soil Interaction during Vibratory Sheet Pile Driving : a Full Scale Field Study

   University essay from KTH/Jord- och bergmekanik

   Author : Claire Guillement; [2013]
   Keywords : Ground vibrations; vibratory driving; sheet pile; full-scale field study; soil instrumentation; sheet pile instrumentation.;

   Abstract : Urban construction sites require strict control of their environmental impact, which, for vibratory sheet pile driving, can include damage to nearby structures due to ground vibrations. However, the lack of knowledge concerning the generation of soil vibrations makes the prediction of ground vibration levels difficult. This MSc. READ MORE
