This report provided a good description of a generic large scale composting plant. In this light, it is useful to those who have little knowledge of how such a facility is composed. Of particular interest is the detailed compo­ sition of the Portland waste stream which is presented and which can be compared to other areas. While the flow diagram is complete, generally it would be more illuminat...

The emergence of digital twin technology presents tremendous opportunities for several industry sectors. A is defined as the virtual representation a physical asset that collects and sends real-time information. data from in uses this to create model object. Its functionality depends on bi-directional coordination between models. This likened cyber-physical systems, which seek provide worlds. W...

The solar chimney power facility has the potential to become a valuable technology for renewable energy production. Its financial viability depends on a thorough understanding of the processes affecting its performance, particularly because of the large startup costs associated with facility design and construction. This paper describes the potential impacts on plant capacity resulting from clo...

machine harvesting of legumes in iran is not being done due to unsuitable variety of the plant, lack of farmers' technical knowledge and farms of small scale sizes.currently the plant is harvested by hand and carried to the thresher: yet application of these threshers is not common; they are few in number, and not very suitable for iran. this presentation shows the design and construction ...

a canola seed pneumatic conveyor was designed and constructed to convey canola seed at a 90 g/hr mass flow rate through a 58 mm diameter pipe. physical and aerodynamic properties of the canola seed that are critical to the design process were measured. system pressure drop, comprising air pressure drop and solid pressure drop and which is the most important aspect of pneumatic conveyor design, ...

The AEC industry will change fundamentally in the next generation, say 25 years. The computer has started to have profound but predictable effects on AEC professional practice. This paper argues that AEC Design and Construction will move toward Desktop Engineering, in which small numbers of computer-based professionals have major responsibility for design and management of entire facility devel...
