Signal-to-noise ratio (SNR) estimation is commonly used in wireless receivers to enhance the performance in different ways. In this paper a novel low complexity SNR estimator for OFDM is proposed. The estimator might be implemented using floating point representation or by using only the sign-bit, and can if desired be effectively implemented by reconfiguring the standard correlator used for time-

The introduction and the diffusion of digital technology have strongly affected the way archaeologists manage and perceive the information detected during the field investigation process. In the last two decades digital instruments have been used in archaeology at any level, and their constant employment increased the opportunities for researchers and scholars to detect, document, analyse and visu

The purpose of this study was to evaluate four different viewing procedures as part of improving viewing conditions of breast tomosynthesis (BT) image volumes. The procedures consisted of free scroll volume browsing, and a combination of initial cine loops at three different frame rates (9, 14 and 25 fps) terminated upon request followed by free scroll volume browsing. Fifty-five normal BT image v

This paper considers evaluation of structural robustness for a multi-span concrete bridge crossing multiple rail tracks, in particular the effect of extraordinary exposures on the bridge system. A case study is performed investigating the bridge system’s response to a train collision caused by derailment in an area near the bridge supports. The probability of such an event occurring is estimated f

Two variants of what looks like disagreement between a subject and a predicative adjective are explored: (i) Senap är gul-t. mustard.COMMON is yellow-NEUT ‘Mustard is yellow.’ = Construction NOM(inal) (ii) Två älskare är omoralisk-t. [two lovers]COMMON.PL is immoral-NEUT ‘To have two lovers is immoral.’ = Construction PROP(ositional) Having shown how Construction NOM and Construction PR

State-of-the-art coverage of compact heat exchanger design and technology. This book, a special supplemental issue of the International Journal of Heat Exchangers, contains a selection of papers originally presented at the Fifth International Conference on Enhanced, Compact, and Ultra-Compact Heat Exchangers: Science, Engineering and Technology, which was held in Whistler, British Columbia, Canad

Popular Abstract in Swedish Användningen av fossila bränslen såsom kol, olja och naturgas svarar för mer än 70% av dagens globala utsläpp av koldioxid vilket är det största antropogena bidraget till växthuseffekten. Energieffektivisering och en ökad användning av förnybara energislag, t ex bioenergi, är två nyckelstrategier för att minska utsläppen av växthusgaser. Ett ökat utnytttjande av bioenerThe increased use of biomass for energy is as a key strategy in reducing carbon dioxide (CO2) emission, which represents the largest anthropogenic contribution to the greenhouse effect. In this thesis, aspects of an increase in the utilisation of biomass in the Swedish energy system are treated. Modern bioenergy systems should be based on high energy and land-use efficiency since biomass resource

The increasingamount of test data needed to test SOC (System-on-Chip) entailsefficient design of the TAM (test access mechanism), which is usedto transport test data inside the chip. Having a powerful TAM willshorten the test time, but it costs large silicon area to implementit. Hence, it is important to have an efficient TAM with minimalrequired hardware overhead. We propose a technique that make
