Correct estimation of symbol timing, Carrier Frequency Offset (CFO), and Signal-to-Noise Ratio (SNR) is crucial in Orthogonal Frequency Division Multiplexing (OFDM) communication. Typically, high estimation accuracy is desired, but often comes with increased complexity. Which has a direct repercussion in energy consumption. In this article, an architecture based on Sign-Bit estimation with low com
This articles discusses the professionalization of human rights NGOs in the Balkans and the consequences for the relation between civil society as social movements, versus Civil Society as a budget category. This latter tendency leads to the rise of the projectization of development, wehereby NGOs simply become project organizations. The result is restrictions on the development of NGOs as the voi
Boken utgör en kulturhistorisk exposé över kakor, tårtor, bakelser och andra sötsaker från antikens Grekland till idag. I boken finns både berättande texter och ett femtiotal recept, ibland i mer än en variant. Samtliga recept är testade och fullt användbara idag. Boken är rikt illustrerad (nytagna färgbilder) och försedd med käll- och litteraturförteckning

The goal of these studies has been to elucidate the biological relevance of post-translational modifications in the context of a living organism. The model system used is photoreceptor differentiation during development of the compound eye in the fruit fly Drosophila melanogaster. Important signal transduction pathways in this process consist of receptor tyrosine kinases (RTKs) coupled to a mitoge
The level structure of Nd-140(60)80 has been established up to spin 48 by in-beam gamma-ray spectroscopy by use of the Zr-96(Ca-48, 4n) reaction. High-fold gamma-ray coincidences were measured with the EUROBALL spectrometer. Twelve new rotational bands have been discovered at high spins. They are interpreted as being formed in a deep triaxial minimum at epsilon(2) approximate to 0.25 and gamma app
In this work, we examine how to reliably exploit baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. Several multilook approaches have recently been suggested to c
Problems related to content of fat, oil and grease (FOG) in wastewater is an increasing problem in Sweden. FOG can cause clogging in the sewage system and subsequent flooding and disturbance of processes in waste water treatment plants. The problem has previously been mostly been related to release of large quantities of FOG from restaurants and large scale industries which has caused problems in

Utvärderingar framställs som attraktiva och oundgängliga samtidigt som det förekommer begränsad kunskap om deras faktiska relevans och om utvärderares arbete. Utvärdering är numera såväl ett självständigt forskningsområde med en vetenskaplig och disciplinär utveckling som en praktik som bedrivs av forskare med vetenskapliga ambitioner, konsulter som arbetar på uppdrag och medarbetare inom organisa
