The four Rainwater Harvesting Systems (RHS) introduced in this work are the following: two rigid, one system built with ferrocement and the other built with clay bricks, and two flexible: one is a commercial collector while the other is a system built with a 3/8-inch reinforcing bar mesh and covered with a linear low-density polyethylene geomembrane. The RHS consist in cylindrical containers built with diverse materials, and in the case of rigid RHSs, they can store up to 50,000 liters of water. Also, rigid RHSs have a longer useful life and are more resistant than flexible RHSs, but their cost is notably higher. Rigid RHSs compete in price with commercial rainwater harvesting system brands like Rotoplas, but commercial RHSs disadvantages are their lower durability, storage capacity, and resistance. On the other hand, flexible RHSs are less durable than rigid ones, although, in the case of the rainwater harvesting system made with a 3/8-inch reinforcing bar mesh, the system can be rebuilt and reused and the cost is much lower. The design of the collectors takes into consideration the climate variability of the study area, natural or anthropogenic.展开更多

The economy of rural residences in the hot summer and cold winter region of China is relative developed, but the indoor thermal environmental quality is not so good. In this paper, the design strategies directed by passive design ideas for a small experimental rural residential building located in Hangzhou city was introduced and researched in response to hot summer and cold winter climate. Through modeling solution undertaken by Ecotect software, the building performance was simulated and analyzed for the optimization of design factors, such as shape, roof angle, insulation system, shading devices, as well as day-lighting system. Based on the above study, a set of appropriate energy-saving technologies were provided for improving the new rural residences construction in Hangzhou, which should also be recommended to other projects constructed in the same climate region.展开更多

Interpretation of Guilin scenery culture could show beautiful and moving natural and cultural artistic charm. In this paper, landscape design measures of Guilin scenery are analyzed from the angle of rural tourism landscape design. Via advocated planning opinion, scientific construction case on rural tourism landscape design of Guilin scenery is proposed, and it is emphasized playing recommendation and presentation role of digital media art on tourism landscape of Guilin scenery.展开更多

But the planning and deployment of these networks are not just a technical matter, since the success depends on many other factors tied to the related region. Although we observe some deployments, to ensure usefulness and sustainability, there is still a need of concrete design process model and proper network planning approach for rural regions, especially in Sub-Saharan Africa. This paper presents a design methodology to provide network connectivity from a landline node in a rural region at very low cost. We propose a methodology composed of ten steps, starting by a deep analysis of the region in order to identify relevant constraints and useful applications to sustain local activities and communication. Approach for planning the physical architecture of the network is based on an indoor-outdoor deployment for reducing the overall cost of the network.展开更多

The asphalt pavement structure, road surface types and thickness of the rural roads are suggested for the various action frequency of the equivalent axle load. Furthermore, the roadbase thickness graphs are provided according to different equivalent axle load action frequency with different roadbed modulus and road surface modulus taken into account.展开更多
