Control of the gliding directions of kinesin-driven microtubules (MTs) in vitro has good feasibility for the development of nano-scale transport systems. A requirement for the control of transporters in these systems includes detecting the positions of gliding MTs;however, no studies have reported on the monitoring of the positions of gliding MTs. Here, we suggest an algorithm to detect tip coordinates of gliding MTs by binarization, skeletonization, and filtration of fluorescent images of MTs. The algorithm was first applied to artificially drawn segments with given lengths (10-80 pixels), widths (1-10 pixels), and curvature radii (20-120 pixels) to verify the effect of the sizes of MTs on accuracy of tip coordinates extracted by the algorithm, and error was estimated by referring to the true coordinates. The estimated errors were as small as 2 pixels in the width and were not affected by the length and the curvature radius, indicating that our algorithm is useful to extract the tips of MTs. The algorithm was subsequently applied to images of gliding MTs. Since distances from the trajectories of the MTs to the centers of gravity of the MTs (3.7 ± 2.1 pixels) were significantly larger than those to the tips (1.9 ± 0.5 pixels), the use of the tips as representative points of gliding MTs was verified. A detection method using tips of MTs, as suggested in this study, may be a useful technique for monitoring each MT in nanoscale transport systems.
The reliability-redundancy allocation problem can be approached as a mixed-integer programming problem. It has been solved by using optimization techniques such as dynamic programming, integer programming, and mixed-i...

The industrialengineering (IE) program at the authors' university receives continued feedback from industry, the IE program Industry Advisory Board (IAB), and student evaluations. This feedback indicated the program needed to provide the senior-level students with a more realistic industry experience. Currently, the IE internship course, IE 471, and industrialsystems Design (IE capstone course), IE 495, are in the IE program curriculum to introduce and provide the senior engineering student an insight into the industrial world. These two courses were evaluated according to the continuous improvement plan for the Accreditation Board for engineering and Technology (ABET) and changes were recommended. The IE 471 Internship is offered to give students an occupational experience in an industrial facility. Students and faculty have experienced several disappointing obstacles in executing this IE 471 internship course, including students being unable to convince industry to hire them for an internship course. The students in the authors' IE program are generally nontraditional students. They are generally older students with family and other responsibilities in addition to their education goals. They are generally working 40 hours per week to support the family and meeting a full-time student curriculum. These students are reluctant to give up their current employment and to work for one semester as an intern. These internships are at minimum wage without benefits for the student and his/her family. The student's current job may not be available when he/she returns after the internship. The disappointments the faculty experience stem from students requesting the faculty advisor to consider using their current job responsibilities as their internship. For example, the student may be working as a sales clerk at a cell phone retail store. This position would have no engineering problems or experience. This paper focuses on the development and implementation of a replacement

To solve large scale 3-D non-stationary incompressible flow problems, an algorithm to perform an Incomplete Balancing Domain Decomposition (IBDD) is constructed in this work; as an improvement of the Balancing Domain Decomposition (BDD) method, it reduce the computation cost of the coarse problem by replacing the exact balancing procedure with an inexact balancing procedure; the nonlinear convection term of the Navier-Stokes equation is approximated by a characteristic-curve method, which is advantageous as it renders the matrix for linear equations symmetric, thus enabling the Conjugate Gradient (CG) method to be used together with the Schur complement system of Domain Decomposition Method (DDM); the algorithms are all implemented in parallel by the Hierarchical Domain Decomposition Method (HDDM) system, and the program provides solvability for models of over 10 million degrees of freedom (DOF).
