Porous surfaces have been used all over the world in source control techniques to minimize flooding problems in car parks. Several studies highlighted the reduction in the infiltration capacity of porous mixture surfaces after several years of use. Therefore, it is necessary to design and develop a new methodology to quantify this reduction and to identify the hypothetical differences in permea...

Airway lengthening after pneumonectomy (PNX) may increase diffusive resistance to gas mixing (1/D(G)); the effect is accentuated by increasing acinar gas density but is difficult to detect from lung CO-diffusing capacity (Dl(CO)). Because lung NO-diffusing capacity (Dl(NO)) is three- to fivefold that of Dl(CO), whereas 1/D(G) for NO and CO are similar, we hypothesized that a density-dependent f...

Midday depression of photosynthesis has important consequences for ecosystem carbon exchange. Recent studies of forest trees have demonstrated that latent reduction of photosynthetic capacity can begin in the early morning, preceding the midday depression. We investigated whether such early morning reduction also occurs in an herbaceous species, Oenothera biennis. Diurnal changes of the photosy...

We measured the channel capacity of an 8×8 multiple-input multiple-output system in a richscattering office scenario at 5.2GHz. We found that there exist remarkable receive positions and directions within a single office, where a strong reduction in MIMO capacity can be observed. Another reduction is due to different transmit array alignment. Investigating the directions-ofdeparture and directi...

isasters have various physical, psychological, social and economical effects on all age groups, particularly children who are more vulnerable than adults. In the aftermath of disasters, children, just like pregnant women, elderly and the disabled, are a special group with special needs. This is because they are at greater risk based on their specific physiological and psychological characterist...

We analyse the impact of distortionless peak-to-average power ratio (PAPR) reduction methods on the ergodic capacity of orthogonal frequency division multiplexing (OFDM) systems in AWGN and frequency selective channels. We consider the following tradeoff: decreasing PAPR increases the efficiency of the linear power amplifier (PA), yielding an increase in the average power emitted and consequent...

The issue of radio frequency interference in Digital Subscriber Line (DSL) networks is of particular concern in urban areas with many strong radio sources nearby. This paper investigates in detail the mechanisms underlying the capacity reduction due to the presence of radio frequency signals from Amplitude Modulated (AM) broadcast stations in an ADSL network. An ADSL system, channel, and radio ...

The application of inorganic nitrogen fertilizers on agricultural landscapes has the potential to generate concerns of environmental degradation at fine to coarse scales across the catchment and landscape. Inorganic nitrogen species (NO3*, NO2*, and NH3) are typically associated with subsurface flow processes; however, surface runoff from rainfall events in no-till agriculture with inorganic su...

While prefetch has proven itself useful for reducing cache misses in multiprocessors, traffic is often increased due to extra unused prefetch data. Prefetching in multiprocessors can also increase the cache miss rate due to the false sharing caused by the larger pieces of data retrieved. The capacity prefetching strategy proposed in this paper is built on the assumption that prefetching is most...

Although capacity development has been identified as the means to substantially reduce global disaster losses, it is a challenge for external partners to facilitate the development of sustainable capacities for disaster risk reduction in disaster-prone countries. The purpose of this study is to investigate potential gaps between how leading professionals approach such capacity development and g...
