In this paper three unit root tests that allow for a break in both the seasonal mean and linear trend of the data are proposed. The tests, which can be seen as smallsample corrected versions of already known asymptotic tests, are shown to perform very well in simulations, and much better than their asymptotic counterparts.
Binding energy shifts between free and solid state atoms for K 2p and Rb 3d photolines have been determined by measuring the vapor and solid state spectra simultaneously in similar experimental conditions applying synchrotron radiation excited photoelectron spectroscopy. This method has the important benefit that the work function is not needed to correct for different reference energy levels, the
Background. The diagnostic work-up and treatment of patients with neuroendocrine neoplasms (NENs) has undergone major recent advances and new methods are currently introduced into the clinic. An update of the WHO classification has resulted in a new nomenclature dividing NENs into neuroendocrine tumours (NETs) including G1 (Ki67 index <= 2%) and G2 (Ki67 index 3-20%) tumours and neuroendocrine car

The use of coarse-grain reconfigurable architectures (CGRA) is a suitable alternative for hardware acceleration in many application areas, including digital holographic imaging. In this paper, we propose a CGRA-based system with an array of processing and memory cells, which communicate using a local and a global communication network, and a stream memory controller to manage data transfers to ext
The accuracy of NOAA AVHRR NDVI maximum value composites can be poor due to interference from several sources, including cloud cover. The objectives of this paper are; 1. to accurately quantify noise in this imagery over Africa using geostatistics, and 2. to test four compositing techniques that may be able to reduce this noise. The nugget of the variogram model is used to compute standardized noi
This case book has been compiled within the framework of Phase III of the programme on Regional Air Pollution in Developing Countries (RAPIDC) funded by the Swedish International Development Cooperation Agency (Sida) and coordinated by the Stockholm Environmental Institute (SEI).

The increasingcost for System-on-Chip (SOC) testing is mainly due to the hugetest data volumes that lead to long test application time andrequire large automatic test equipment (ATE) memory. Testcompression and test sharing have been proposed to reduce the testdata volume, while test infrastructure and concurrent testscheduling have been developed to reduce the test application time.In this work w
The objective of the seminar was to summarize, discuss, question and conclude the present state-of-the-art on prediction models for corrosion initiation due to chloride ingress in structures exposed to sea water and de-icing salts. Papers were presented on various topics. A test case was designed and the experts made predictions of chloride ingress for this well-defined case.
The paper argues that the final value of an object, i.e., its value for its own sake, need not be intrinsic. It need not supervene on the object’s internal properties. Extrinsic final value, which accrues to things (or persons) in virtue of their relational features, cannot be traced back to the intrinsic value of states that involve these things together with their relations. On the opposite, suc
Popular Abstract in Swedish Denna avhandling består av en tillämpad och en teoretisk del. I den tillämpade delen studeras tänkbara riskfaktorer för blodsjukdomarna myeloisk leukemi (ML) och myelodysplastiska syndrom (MDS). Den teoretiska delen tar upp några metodproblem som kan uppstå i epidemiologiska undersökningar som utnyttjar databaser innehållande uppgifter om andelen personer i olika yrkesgCase-control studies comprising telephone interviews for 333 cases of acute myeloid leukemia (AML), 226 cases of Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML), 330 cases of myelodysplastic syndromes (MDS), and matched controls were conducted. Information had to be obtained from next-of-kin much more often for cases (85%) than for controls (18%). Tobacco smoking was associated
