Abstract in Undetermined To ensure that sufficient image quality is obtained in diagnostic radiology, the image quality of clinical radiographs has to be evaluated. We present two methods herein for evaluating antero-posterior (AP) radiographs of the lumbar spine. One was using image criteria, including six anatomical details (absolute method). In the other, the visibility of anatomical details re

Experimental branching fractions (BFs) of Mo (II,) ranging in wavelength from 1970 to 4370 Angstrom, have been measured from intensity calibrated spectra recorded with the Lund UV Fourier transform spectrometer (FTS). Radiative lifetimes for 10 levels have been measured using the method of laser-induced fluorescence (LIF). Combining BFs with new as well as previously measured lifetimes, 16 in tota

Carotid endarterectomy (CEA) is a standardized surgical procedure and is the third most common vascular surgical procedure in Sweden. To improve the quality of pre- and postoperative care for patients undergoing elective CEA, a standardized care plan (SCP) was developed and implemented during Spring of 2007 at a vascular clinic in Sweden. In order to spread light on obstacles and possibilities in

In this article, we consider scenarios in which traditional estimates for the active subspace method based on probabilistic Poincaré inequalities are not valid due to unbounded Poincaré constants. Consequently, we propose a framework that allows to derive generalized estimates in the sense that it enables to control the trade-off between the size of the Poincaré constant and a weaker order of the

The mechanical and electrical response of acoustophoretic microfluidic devices attached to an ac-voltage-driven piezoelectric transducer is studied by means of numerical simulations. The governing equations are formulated in a variational framework that, introducing Lagrangian and Hamiltonian densities, is used to derive the weak form for the finite-element discretization of the equations and to c

The ability to draw other agents’ attention to objects and events is an important skill on the critical path to effective human-robot collaboration. People use the act of pointing to draw other people’s attention to objects and events for a wide range of purposes. While there is significant work that aims to understand people’s pointing behavior, there is little work analyzing how people interpret

In year 2017 the WWN+ project "Silent Timber Build" is finishing. The project focused on studying timber structures with regard to their sound insulation characteristics, both airborne sound insulation and impact sound insulation. The aim is to develop calculation models (and / or to provide input to standardized models) for various timber structures available in Europe but also to facilitate futu

Rationale: Several guidelines exist that address treatment of patients with nonmetastatic muscle-invasive bladder cancer (MIBC). However, most only briefly mention follow-up strategies for patients and hence the treating physician is often left to infer on what the preferred follow-up schema would be for an individual patient. Herein, we aim to synthesize recommendations for follow-up of patients

The Davies transformation is a method to transform the steering vector of a uniform circular array (UCA) to a vector with Vandermonde form. As this form is similar to that of the steering vector of a uniform linear array (ULA), we can apply to UCAs the many tools that have been developed for ULAs. However, the Davies transformation can be highly sensitive to perturbations of the underlying ideal a

Periodic boundary conditions (PBC) are well suited to describe repetitive structures in space, yet flawed for isotropic setups in which it is commonly used. We present an approach based on exploiting the congruency of a unit cell which combines the periodic nature of PBC with isotropy of an alternating cell. By applying these isotropic periodic boundary conditions (IPBC) to the standard Ewald summ

Software-Defined Networking (SDN) is a novel architectural model for cloud network infrastructure, improving resource utilization, scalability and administration. SDN deployments increasingly rely on virtual switches executing on commodity operating systems with large code bases, which are prime targets for adversaries attacking the network infrastructure. We describe and implement TruSDN , a fr

This paper presents the architecture and the corresponding simulation results for a very low power half-rate extended Hamming (8,4) decoder implemented in analog integrated circuitry. TI’s 65nm low power CMOS design library was used to simulate the complete decoder including an input interface, an analog decoding core and an output interface. The simulated bit error rate (BER) performance of the d
