For a gas station training simulation system, the real time and reality of scene directly affect the application of system. In order to solve this problem, we used 3D virtual scene building technology based on OpenSceneGraph (OSG) to build gas station scene. Technology of levels of detail (LOD) was used to improve the real-time ability of the system during entity modeling. And then based on 3D entity model library and information files in Extensible Markup Language (XML), we built the parametric library and set up the gas station scene, which provided function information and attribute information. Experimental results show that the scene of virtual gas station can not only greatly improve the reality and immersion of system, but also well support the real-time simulation. Now, 3D virtual scene building technology based on OSG has applied successfully in gas station training simulation system, which provides feasible evidence for engineering simulation to solve practical problems.

<p>The Netherlands plans to cut greenhouse gas emissions by 1 megaton CO<sub>2</sub>-equivalents in 2030 by implementing measures reducing peat decomposition. In order to achieve this, a national research program on peatland pasture greenhouse gas emissions has been set up. In the program, five peatland sites with each two fields, with and without submerged tube drainage systems, are continuously monitored. Here, we present our research with the objective to understand the rate of biochemical peat decomposition by assessing electron acceptor availability from a hydrological perspective. Soil (< 100 cm depth) redox conditions are continuously measured at five depths. Preliminary data on soil electron acceptor availability distribution suggest counterintuitive behavior of the peat soils. We find reducing conditions in the topsoil (0-20 cm) and oxidative conditions in the subsoil (40-80 cm) for the sites without tube drainage. For sites with tube drainage, we find oxidative conditions in the topsoil (0-20 cm) and reducing conditions starting at 60 cm depth at the drain location and at 80 cm depth between the drains. A novel 2D groundwater model is being set up, enabling to capture saturation dynamics, water origin and solute transport in the peat soil. We will present our modelling setup and initial simulation results for water origin and travel paths. These results will indicate how electron acceptors are distributed through the soil, helping to interpret redox measurements in the field at different depths. In a later stage of the research, the effects of redox conditions on microbial soil respiration will be evaluated with greenhouse gas chamber and eddy covariance measurements.</p>

Abstract. A major link between climate and humans in tropical northern Africa, and the Sahel in particular, is land use and associated land cover change, mainly where subsistence farming prevails. Here we assess possible feedbacks between the type of land use and harvest intensity and climate by analysing a series of idealized GCM experiments using the Max Planck Institute Earth System Model (MPI-ESM). The baseline for these experiments is a simulation forced by the RCP8.5 (radiation concentration pathway) scenario, which includes strong greenhouse gas emissions and anthropogenic land cover changes. The anthropogenic land cover changes in the RCP8.5 scenario include a mixture of pasture and agriculture. In subsequent simulations, we replace the entire area affected by anthropogenic land cover change in the region between the Sahara in the north and the Guinean Coast in the south (4 to 20\\degree N) with either pasture or agriculture. In a second set-up we vary the amount of harvest in the case of agriculture. The RCP8.5 baseline simulation reveals strong changes in the area mean agriculture and monsoon rainfall. In comparison with these changes, any variation of the type of land use in the study area leads to very small, mostly insignificantly small, additional differences in mean temperature and annual precipitation change in this region. These findings are only based on the specific set-up of our experiments, which only focuses on variations in the kind of land use, and not the increase in land use, over the 21st century, nor whether land use is considered at all. Within the uncertainty of the representation of land use in current ESMs, our study suggests marginal feedback between land use changes and climate changes triggered by strong greenhouse gas emissions. Hence as a good approximation, climate can be considered as an external forcing: models investigating land-use–conflict dynamics can run offline by prescribing seasonal or mean values of climate as a boundary condition for climate.

Series of GNSS receiver tests allowed to determine real accuracy of RTN measurements. Repeated measurements allowed to estimate accuracy in function of used navigation satellite system, duration of measurements and field conditions on measurement site which are related to horizon visibility by obstacles (bushes). Research results indicate no dependency between the technology used and the measurement accuracies obtained and significant impact of the conditions on set-up on the measurement's results.

Reliability optimum design of the mechanical system is studied thoroughly based on the existing research results. Taking the 2K-H planetary reducer of PCP system as the physical mode, the main target of optimization is module, breadth of tooth and number of teeth. The objective function for obtaining a smaller gearbox volume is set up and the requirement of reliability is taken into account. The optimum solution is obtained by the complex method. The result is in conformity with the requirement and it indicates that the synthesis effect is satisfied. The reduction of volume is beneficial to improve PCP system performance.

Manure management is the main strategy for mitigating gas emissions from livestock farming. In this study, a laboratory-scale experiment was set up to identify suitable conditions to be applied in a farm-scale experiment. The liquid fraction (LF) of slurry was aerobically treated and greenhouse gas emissions from soil were evaluated. Furthermore, the value of treated LF as a fertilizer on spinach plants was also tested. The aeration of LF determined an increase in mean alkalinity due to ammonia loss. The mass fraction of heavy metals also decreased, likely due to the reduction in solubility. After being applied on soil, aerated LF determined lower CO2 and N2O emissions compared to untreated LF due to a reduced nitrogen load. Spinach plants fertilized with treated LF showed a lush growth and exhibited a lower heavy metal mass fraction as well as a higher content of antioxidants compared to plants fertilized with untreated slurry. Our results show that aeration might be an effective alternative for slurry management as it is able to produce an eco-friendly final product with a high fertilizing value.

The purpose of this research is to know the performance of queue service and to find solutions to overcoming queues at Liliba gas station. This study using the observation method. Based on the observation data obtained and then set up a calculation of the observed system. The data analysis method uses multiple line queue models (Single Channel – Multi Phase). Data in the analysis is descriptively quantitative and qualitative. The results derived from such calculations are noticeable that there is a queue in the afternoon. So that the solution is given that in the period of busy time or at the time there is a long queue, companies should divert motorcycle customers to the car line if on the car line there is no queue, so it can improve efficiency of service at Liliba gas station. Keywords : Queueing Theory, Queueing Model
