Low-Complexity MMSE Combining for Linear Impulse Radio UWB Receivers

Due to the fine delay resolution of typical ultra wideband (UWB) systems, Rake receivers need to combine samples from a large number of multipath components (MPCs) in order to collect sufficient signal energy for reliable decisions. In addition, these samples need to be combined optimally in order to minimize bit error probability. The optimal linear minimum mean square error (MMSE) combining sche

Unveiling the Concept of Packaging Logistics

An increasingly competitive environment, technological advancements and globalisation are a few of the factors placing higher demands on today’s company activities, e.g. development, production and distribution processes. Company activities have hereby become a complex system, even more so if one company is seen as part of a network of companies. The aim of this article is to present and elaborate

The Explicit Body: Feminist Performance as Sex Education

In 1990 the performance artist, porn star, photographer and sex workers’ rights activist Annie Sprinkle presented her Post Post Porn Modernist: Still in Search of the Ultimate Sexual Experience. This show included the section “Public Cervix Announcement” (PCA) in which Sprinkle presented the audience with two large, oval shaped, colored drawings: one a cartoonish rendering of the female reproducti

Mixed Integer Programming Model of MCCA-aware Acknowledging in Wireless Mesh Networks

The paper investigates advantages of using an MCCA-aware acknowledging system in IEEE 802.11s Wireless Mesh Networks (WMN). The MCCA (MCF controlled channel access) protocol allows for reserving time slots for a point-topoint transmission over a wireless link. The protocol assures that the transmission will not be hindered by any other 802.11 device that uses MCCA, by preventing all neighbors of b

Deaths and tumours in workers grinding stainless steel - a follow-up study

OBJECTIVE: To study cause specific mortality and cancer morbidity in workers exposed to the dust of grinding materials, grinding agents, and stainless steel, especially with regard to a possibly increased risk of respiratory, stomach, and colorectal cancer. METHODS: Retrospective cohort study, using reference cohorts of blue collar workers and population rates for comparison. The exposed cohort c

Vertical temperature increase in multi-storey buildings

Indoor temperature is by measurements stated to rise 0.1 – 0.2°C per storey upwards in multi-storey buildings, despite occupants’ possibility to control the temperature. Due to upward air temperature gradient in rooms there will be a heat transfer through slabs upwards. The size of this depends on insulation degree of building envelope and slabs and air flow through the building. With a linear mat
