We propose new feature-based methods for rigid and affine image registration. These are compared to state-of-the-art intensity-based techniques as well as existing feature-based methods. On challenging datasets of brain MR and whole-body CT images, a significant improvement in terms of speed, robustness to outlier structures and dependence on initialization is shown.

As a cost-effective option for Cloud consumers, spot service has been considered to be a significant supplement for building a full-fledged market economy for the Cloud ecosystem. However, unlike the static and straightforward way of trading on-demand and reserved Cloud services, the market-driven regulations of employing spot service could be too complicated for Cloud consumers to comprehensively

Blind channel equalization has gained great importance in the world of communications. Among a large number of available blind equalization algorithms, the CMA (Constant Modulus Algorithm) enjoys widespread popularity because of its LMS-like complexity and robustness. Two important improvements on the CMA performance are the Dithered Signed-Error CMA (DSE-CMA) and the Pre-Whitened CMA (PW-CMA). Th

The purpose of an indoor climate system is to fulfil the required thermal comfort and provide satisfactory indoor air quality by using as little resources as possible. This study investigated the resulting energy use and life cycle cost from different ventilation systems for typical single family houses in the Nordic outdoor climate. Three ventilation systems were compared, namely exhaust ventilat

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

We present an incremental energy minimization model for magnetic shape memory alloys (MSMAs) whose derivation departs from the constrained theory of magnetoelasticity [1], but additionally accounts for elastic deformations, magnetization rotation, and dissipative mechanisms. The minimization of the proposed incremental energy yields the evolution of the internal state variables. In this sense, the

At Lund University an automated video analysis system is being developed that can be applied for studying the behaviour of road users in complex traffic environments. It is stressed that system must be capable of handling all the categories of road users, i.e. vehicles, pedestrians and cyclists. Common problems like detection and tracking of moving objects, occlusion by foreground objects, ground-

We propose a simple, general and computationally efficient algorithm for maximum likelihood estima- tion (MLE) of parameters in diffusion and jump-diffusion processes. This is conducted within a Monte Carlo EM-algorithm, where the smoothing distribution is computed using resampling. The results are encouraging as we can approximate the MLE well for the models studied when using simulated data. We

We present an approach to process scheduling based on an abstract graph representation which captures both data-flow and the flow of control. Target architectures consist of several processors, ASICs and shared busses. We have developed a heuristic which generates a schedule table so that the worst case delay is minimized. Several experiments demonstrate the efficiency of the approach.

A general approach to derive summation rules in electromagnetics using Herglotz functions is presented in this paper. This approach is then used to obtain summation rules and bounds on partial wave scattering, which are illustrated numerically by the scattering of a Drude sphere.

The Somalia Reconciliation Conference led by the Intergovernmental Authority on Development (IGAD), in Eastern Africa, is focusing on creating a basis for dialogue as a means of reaching peace and stability in the region (Somali Reconciliation Conference, 2003; IGAD, 2002). This paper deals with the critical implications with focusing on dialogue as a means of promoting long-term peace.
