We minimize the frequency and time occupancy of multicarrier binary linear modulation based on two-dimensional faster than Nyquist (FTN) signaling. FTN analysis provides the asymptotic time–frequency consumption per bit and prolate spheroidal wave analysis minimizes the side lobe occupancy. For both problems, an excellent choice is a Gaussian pulse, with some adjustment of the side lobes.
Classifying images of HEp-2 cells from indirect immunofluorescence has important clinical applications. We have developed an automatic method based on random forests that classifies an HEp-2 cell image into one of six classes. The method is applied to the data set of the ICPR 2012 contest. The previously obtained best accuracy is 79.3% for this data set, whereas we obtain an accuracy of 97.4%. The
Popular Abstract in English Wild fruits trees species are widely distributed throughout the African countries. Many of these trees species produce fruits, which are used by the local communities to greater or less degrees. The importance of wild fruits in the diet depends to a large extent on the availability of the fruits, since cultivated fruit trees are not particularly common in the dry regionAbstract Wild fruit trees have significant cultural and socio-economic value in rural areas of Mozambique. Most of the wild fruits are seasonal and are available mainly in the wet season. Generally they have a short shelf-life and are eaten fresh or after minimal processing; the most common method of preservation is sun-drying. The fruits of Adansonia digitata, Landolphia kirkii, Salacia kraussii,
High-spin states in Kr-74 were studied using the 40Ca(40Ca,alpha 2p)74Kr fusion evaporation reaction at a beam energy of 165 MeV with Gammasphere and Microball and at a beam energy of 185 MeV with Euroball and Isis muli-detector arrays. Lifetimes of the high-spin states for the ground state band and the favoured negative parity band have been determined using the Doppler-shift attenuation method.
The calculation of isothermal moisture transport requires a moisture flow coefficient, Dφ(φ,T), for isothermal flow with φ as the moisture state variable. In the non-isothermal case, a second flow coefficient, DTφ(φ,T), is required to account for the temperature gradient. This means that a number of isothermal measurements are required for a few different temperature levels. It also means that a c
This book deals with the impact of the free movement rules in the EC Treaty on tax treaties in the internal market. This is a highly relevant issue since a provision in breach of teh free movement rules is inapplicable. The potential far-reaching consequences following the preclusion of tax treaty provisions makes it important for taxpayers and governments of teh Member States of teh EU to predict
Popular Abstract in Swedish Företagen har mer och mer problem att generera och utveckla kunskaper i samarbete med andra, enskilda företag. Forskare inom det teoretiska område kooperativ inlärning har börjat att undersöka hur partnerorganisationer lär sig att samarbeta med varandra. Men det specifika inlärningsinnehållet av denna kollektivt inlärda kunskap är generellt inte något de fokuserar på. DBusiness organizations increasingly face the problem of how to generate and share knowledge in collaboration with other, separate, business organizations. Researchers in the field of inter-organizational learning have started to study the partner-characteristic, partner-dynamic, and partner-situational factors that influence the process and outcome of such strategic learning collaboration. However
We investigate WiMAX mesh networks in terms of delay and throughput trade-off. For a given topology, using our proposed analytical model we study how slot allocation policy and forwarding probability affects per-node and network performance.
