The National Science Foundation has recently approved funding for LENS (the low energy neutron source) at Indiana University and construction of this facility has begun. LENS represents a new paradigm for economically introducing neutron scattering into a university or industrial setting. In this design, neutrons are produced in a long-pulse (1 ms) mode through (p,n) reactions on a water-cooled...

In this paper, a feasibility study of building a Human Powered Hydrofoil (HPH) vessel is reported. Hydrofoil vessels are a well-known class of high-speed crafts. In addition to high-speed operation, the hydrofoils have a reliable maneuvering capability, good stability and proper operation in waves. Also, a human powered vehicle, nowadays is an advancing idea. Different aspects of the design and...

The main objective of this paper is to identify the design criteria for a BIM Education Resilient System STEM program. The curriculum’s development will semantically relate to resilience concepts with Systems Engineering and Building Information Modeling (BIM) practices and standards. The Sustainable Facilities and Infrastructure in Constrained Environments’ (SuFICE) in advancing STEM to Suppor...

In this paper, a quaternion firefly algorithm is utilized to solve a multi-row facility layout design problem with the objective of minimizing the total cost of transportation. A quaternion firefly algorithm takes the motion of the firefly as a quaternion one. Consequently, the solution space is explored more accurately and the answers are of higher quality. That is, the answers are considerabl...

It is the cost estimator’s task to determine how the building design influences construction costs. Estimators must account for how and when features of building product models affect the project’s activities, resources, and resource productivity rates that form the basis of a cost estimate. Without explicitly representing estimators’ rationale for relating product and cost information in the c...

regarding the importance sizing and grading crop in the market and other processing operations, in this study, a machine for hazelnut sizing designed, constructed and evaluated. the machine based on sizing mechanism of diverged belt. the sizing unit has a structure similar to a horizontal belt conveyor. the distance between the ropes at the entrance of the product (the end of the driven roller)...
