Physical limitations on antennas: isoperimetric inequalities and the effect of metamaterials
In this paper, physical limitations on antennas are presented based on the holomorphic properties of the forward scattering dyadic. As a direct consequence of causality and energy conservation, a forward dispersion relation for the extinction cross section is established, and isoperimetric inequalities for the partial realized gain and partial directivity are derived for antennas of arbitrary shap
A Study of Marine Incidents Databases in the Baltic Sea Region
A comprehensive risk analysis makes use of different datasets. Marine incidents data are essentially important datasets. The purpose of this study is to analyse marine incident databases in the BSR (Baltic Sea Region). The marine incident data in the region are inhabited by a wide rage of issues, such as limited data accessibility and availability, and the diversity in data quality, structure, amo
Challenges in the treatment of malignant glioma with oncolytic adenovirus
Malignant glioma is a tumor that spreads rapidly throughout brain and is almost impossible to remove completely by surgery. It is resistant to chemo- and radiotherapy and the prognosis is very poor. As a result, there is a desperate need for development of novel therapies against this devastating disease. Because of the heterogeneity in this cancer success has been limited, but a recent concept in
Signal Estimation over Channels with SNR Constraints and Feedback
We consider the problem of designing optimal linear encoders and decoders for estimation and transmission of a signal over an analog communication channel with additive noise and a signal-to-noise ratio (SNR) constraint. The objective is to minimize the variance of the estimation error at the receiving end, subject to a real-time constraint. It has been previously shown that, for channels without

A Case Study in Model Reduction of Linear Time-Varying Systems
In this paper, the balanced truncation procedure is applied to time-varying linear systems, both in continuous and in discrete time. The methods are applied to a linear approximation of a diesel exhaust catalyst model. The reduced-order systems are obtained by using certain projections instead of direct balancing. An approximate zero-order-hold discretization of continuous-time systems is describe
