Perturbation problems for operators with embedded eigenvalues are generally challenging since the embedded eigenvalues cannot be separated from the rest of the spectrum. In this paper we study a perturbation problem for embedded eigenvalues for the bilaplacian with an added potential, when the underlying domain is a cylinder. We show that the set of nearby potentials, for which a simple embedded

Employing fault tolerance often introduces a time overhead, which may cause a deadline violation in real-time systems (RTS). Therefore, for RTS it is important to optimize the fault tolerance techniques such that the probability to meet the deadlines, i.e. the Level of Confidence (LoC), is maximized. Previous studies have focused on evaluating the LoC for equidistant checkpointing. However, no stu

Several different strategies are effective for medical treatment of motor problems in Parkinson's disease (PD). Many guidelines and evidence-based reviews are available, but there is no documentation or consensus in favor of just one treatment strategy. This review presents two algorithms that may be helpful when deciding how to treat a PD patient at various stages of the disease. The first algori

The Integral Quadratic Constraint (IQC) framework developed by Professor Yakubovich and his co-workers, see Yakubovich et.al. (2004), is one of few available constructive tools for establishing robust stability of nonlinear systems. An explicit format of stability conditions, procedures for computing a Lyapunov function and developed libraries IQCs for common nonlinearities in dynamics, all togeth

Background: Residual air accumulated air in the pulmonary veins constitutes a challenge to achievment of complete de-airing in open left heart surgery. To adress this problem, a conceptual method for de-airing was developed in Lund comprising bilateral opening of the pleurae to induce pulmonary collapse and a strategy with gradual pulmonary reperfusion and ventilation at weaning from cardiopulmona

Today’s communities are characterized by migration, transnationalism, and participation in the global economy, and many also have long local histories of linguistic diversity. Empowering individuals in these contexts means fostering the ability to use and expand their existing linguistic repertoires so they can take advantage of the social and economic opportunities afforded by contemporary life.

Contact allergy induced by certain chemicals is a common health concern, and several alternative methods have been developed to fulfill the requirements of European legislation with regard to hazard assessment of potential skin sensitizers. However, validated methods, which provide information about the potency of skin sensitizers, are still lacking. The cell-based assay Genomic Allergen Rapid Det

A method was developed, which drives the selection of appropriate solar control mechanisms based on theanalysis of overheating due to solar heat gains. The aim of the method is to maintain adequate thermalcomfort levels in highly glazed spaces. Two thermal comfort models, Predicted Mean Vote and AdaptiveModel, were chosen to set the thermal comfort boundaries included in the method. Moreover, in o

Prevention is viewed as a key issue for general practice, yet there is a lack of evidence regarding general practitioners’ interventions in both middle-aged and elderly people. This is despite the fact that recommendations and key indicators for monitoring the use of clinical preventive strategies aimed at these groups are available and that both the World Health Organization and European Commissi

We report the first high spectral resolution study of 17 M giants kinematically confirmed to lie within a few parsecs of the Galactic center, using R ~ 24,000 spectroscopy from Keck/NIRSPEC and a new line list for the infrared K band. We consider their luminosities and kinematics, which classify these stars as members of the older stellar population and the central cluster. We find a median metall

Established approaches to data aggregation in wirelesssensor networks (WSNs) do not cover the variety of new usecases developing with the advent of the Internet of Things. In particular,the current push towards fog computing, in which control,computation, and storage are moved to nodes close to the networkedge, induces a need to collect data at multiple sinks, ratherthan the single sink typically
