This paper describes power optimization techniques applied to a reconfigurable digital finite impulse response (FIR) filter used in a Universal Mobile Telephone Service (UMTS) mobile terminal. Various methods of optimization for implementation were combined to achieve low cost in terms of power consumption. Each optimization method is described in detail and is applied to the reconfigurable filter

This paper investigates to what extent and how the sociological perspective of Erving Goffman is represented in Swedish sociology-textbooks and why it is represented the way it is. The investigation has been restricted to central Swedish textbooks during the period 1970-2000 and consequently it does not give a complete picture, but since the choice of textbooks reflects central currents and person

Purpose: The study aims to focus on rotation effects on a ribbed channel of gas turbine blades for internal cooling. The combination and interaction between secondary flows generated by angled rib geometry and Coriolis forces in the rotating channel are studied numerically. Design/methodology/approach: A radially outward flow passage as an internal cooling test model with and without ribs is used

In this paper, we will present some of our findings from a study conducted on legislative measures related to the online infringement of intellectual property rights commissioned by the European Union Intellectual Property Office (EUIPO) on legislative measures related to online intellectual property rights infringements. The present summarizes the mapping the existing legislative national measure

We demonstrate fluidics realized in thin film plastic foils patterned using roll-toroll nanoimprinting lithography (rrNIL). Realizing fluidics devices in thin plastic foils opens up for parallel operation in stacked devices. It also provides a convenient format for storage and distribution of the devices.

We present experimental results and simulations on a simple method for tunable particle separation based on a combination of Deterministic Lateral Displacement (DLD) and Insulator Based Dielectrophoresis (I-DEP). Rather than deriving its tunability from its elastic properties[1], our present device uses an applied AC field to perturb the particle trajectories in the pressure-driven flow and is the

The local alignment of DNA stretched in nanofluidic channels is measured using polarization sensitive detection. With increased degree of stretching the polarization anisotropy increases both in the deGennes and the Odijk regime. The technique is expected to find use in studies of, for example, local conformational changes in polymer physics in confined spaces, studies of protein-DNA interactions

Objective: To describe the prevalence, baseline characteristics and factors associated with survival in out-of-hospital cardiac arrest (OHCA) with initial non-shockable rhythm sub-grouped into pulseless electrical activity (PEA) and asystole as presenting rhythm. Methods: The Swedish Registry of Cardiopulmonary Resuscitation is a prospectively recorded nationwide registry of modified Utstein param

OBJECTIVES: To evaluate knowledge translation after publication of the target temperature management 33°C versus 36°C after out-of-hospital cardiac arrest trial and associated patient outcomes. Our primary hypothesis was that target temperature management at 36°C was rapidly adopted in Australian and New Zealand ICUs. Secondary hypotheses were that temporal reductions in mortality would be seen an

Human activities and climate change affect hydrological and sedimentological characteristics within catchments. For arid and semiarid areas this induces direct negative economic and environmental consequences on society. In fact, stability in the rainfall regime and less siltation trapped in reservoirs mean more water for irrigation, water supply, and better flood control. This is especially impor

Purpose: The fluid flow in a rotating channel is obviously different from that in a stationary channel due to the existence of Coriolis force, which, in turn, enhances the heat transfer on the trailing side and reduces the heat transfer on the leading side. The purpose of this paper is to study various rib configurations combined with channel orientation on heat transfer and frictional loss in a r

Purpose: This study aims to clarify the mechanism of film hole location at the span-wise direction of an internal cooling channel with crescent ribs on the adiabatic film cooling performance, three configurations are designed to observe the effects of the distance between the center of the ellipse and the side wall(Case 1, l = w/2, Case 2, l = w/3 and for Case 3, l = w/4). Design/methodology/appro

The additional passing lanes and 2+1 roads improve significant road safety. Studies indicate sections with additional passing lanes (relief or alternately), which may cause reduction in the number of accidents by 50%. However, how geometric design affects the safety performance of such sections is not in depth investigated. Previous studies are carried out with two approaches, i.e. the most often,
