龙门山雁门坝地区下、中泥盆统界线的腕足动物序列

本文在龙门山雁门坝泥盆系剖面下中统交界区划分出4个腕足化石带。依据现代地层学原则,将下中统界线确定在甘溪组顶部,以Xenospirifer fongi的首次出现为标志,此界线与国际界线层型相当。文中提出了在无指定化石带地区确定年代地层单位界线的方法。论证该段剖面沉积环境属泥质浅海陆棚。描述4个腕足动物新种。

Traffic modeling in a reconfigurable broadband nomadic computing environment

Reconfiguring a network to counter variations in traffic is expected to greatly enhance optimal usage of network resources. But an important input to this method is the traffic fluctuations themselves. We have developed two models for this purpose to describe the time-dependent variations in traffic at a base station in a nomadic computing, wireless environment. The first model is rather simple and does not take into account details of human behavior. It takes into account the probabilities of choosing different applications. The model is also analyzed and experimented with to identify the important input parameters. The second model, a refined version of the first model, takes into account details of relevant human behavior (in the context of a wireless nomadic computing environment). Finally, we have compared the two models on the basis of their complexity and validity in different situations.     

Internalisation of external cost in the power generation sector: Analysis with Global Multi-regional MARKAL model

The Global MARKAL-Model (GMM), a multi-regional “bottom-up” partial equilibrium model of the global energy system with endogenous technological learning, is used to address impacts of internalisation of external costs from power production. This modelling approach imposes additional charges on electricity generation, which reflect the costs of environmental and health damages from local pollutants (SO₂, NO_x) and climate change, wastes, occupational health, risk of accidents, noise and other burdens. Technologies allowing abatement of pollutants emitted from power plants are rapidly introduced into the energy system, for example, desulphurisation, NO_x removal, and CO₂ scrubbers. The modelling results indicate substantial changes in the electricity production system in favour of natural gas combined cycle, nuclear power and renewables induced by internalisation of external costs and also efficiency loss due to the use of scrubbers. Structural changes and fuel switching in the electricity sector result in significant reduction of emissions of both local pollution and CO₂ over the modelled time period. Strong decarbonisation impact of internalising local externalities suggests that ancillary benefits can be expected from policies directly addressing other issues then CO₂ mitigation. Finally, the detailed analysis of the total generation cost of different technologies points out that inclusion of external cost in the price of electricity increases competitiveness of non-fossil generation sources and fossil power plants with emission control.     

Large-scale lateral spreading and related mass movements in the Northern Calcareous Alps

Lateral spreading is an important geotechnical phenomenon in the Hallstatt zones of the Northern Calcareous Alps where rigid limestones overlie marls and salt clays. Following the last glaciation, mass movements have developed with a general spreading of limestone blocks resulting in a complicated jigsaw puzzle of rock. Two typical examples from Mt. Sandling and Mt. Raschberg in the Northern Calcareous Alps of Austria are discussed.     

Characterization of terrain surface and mechanisms of shallow landsliding in upper Kurokawa watershed,Mt Aso,western Japan

The paper describes the physical characteristics of the Mt Aso caldera (western Japan) where some 959 shallow landslides occurred between 1990 and 1998, denuding an area of 0.638 km². The variation in type and thickness of the recent pyroclastic deposits are described and linked to the spatial distribution of the landslides. The high monsoonal rainfall in July 1990 percolating into the recently deposited tephra overlying less permeable bedrock first saturated the soil mass and then effectively ‘floated’ the low density pyroclastic materials such that many slips occurred in the small, actively eroding, tributary valleys.      

Emissions targeting and planning: An application of CO2 emissions pinch analysis (CEPA) to the Irish electricity generation sector

This paper outlines the past analysis and projected planning of the Irish electricity generation sector using an extension of a novel methodology based on a graphical optimisation concept. The main two adaptations/extensions to the current form of the methodology are proposed as both the forecasting adaptation and the extension that accounts for the dynamic nature of electricity supply–demand. The determination of an optimal energy resource (OER) mix (or optimal fuel mix) for the sector will look to give guidelines towards fulfilling the sector's Kyoto targets, as well as yielding a possible approach for other sectors to follow in the future. Data pertaining to the sector for the year 2005 was taken in order to illustrate the analysis and forecasting procedures.
