Sea spray icing can pose a risk to offshore structures in cold climate, affecting the operability and in the worst case the stability of the structure. One of the most uncertain parameters when attempting to estimate the design load from sea spray icing is the flux of sea water reaching the topside....

The requirements for data rate and capacity in wireless communication systems have increased dramatically over the last couple of decades, and it is expected that this increase will continue in the years to come. Including higher frequency bands providing additional bandwidth is a key strategy to me...

An 5.1 μW, 1.8 V, 8-bit, successive approximation (SAR) analog-to-digital converter (ADC) using 10 kHz clock was designed and fabricated in a 0.18 μm CMOS technology for passive UHF radio frequency identification (RFID) applications. The ADC utilises a resistive digital to analog converter (DAC). Th...

A lightweight MAC and network layer protocol suite for underwater acoustic communication has been developed. The protocol suite covers the MAC layer, hop-by-hop acknowledgement, multi-hop routing and transmission and includes a network discovery and route generation module.The protocols are currentl...

The unique properties of fractals have been exploited to develop a new class of antenna element designs that are multi band and compact in size. These properties are very important for RFID (Radio Frequency IDentification) tags where the small size, planar geometries, multi band operation and low co...

SINTEF har utviklet en satellitt-demodulator for Kongsberg Spacetec. Denne arbeider med en innkommende sampelrate fra AD-konverter på 1,4 gigasampler/s og datarater opp til flere hundre Mbit/s. Med dette FPGA-designet som eksempel vil vi se på utfordringer og løsninger for implementas...
