This study introduces a new hybrid design for a specific case of assembly lines, and proposes a multi-pass random assignment algorithm to find the minimum number of stations required. The algorithm also finds the sequence and the schedule of the tasks assigned. The new design is a combination of two-sided lines and U-shaped lines, which benefits from the(More)
This paper demonstrates and compares different experimental techniques utilized to estimate the quality factor (Q) and natural frequency from non-contact measurements of Microelectromechanical Systems (MEMS) motions. The relative merits of those techniques are contrasted in Q factor estimation for a cantilever beam MEMS actuator, operated in three(More)
We studied the exposure behavior of low molecular weight polystyrene as a negative tone electron beam lithography (EBL) resist, with the goal of finding the ultimate achievable resolution. It demonstrated fairly well-defined patterning of a 20-nm period line array and a 15-nm period dot array, which are the densest patterns ever achieved using organic EBL(More)
Integrating plasmonic materials, like gold with a two-dimensional material (e.g., graphene) enhances the light-material interaction and, hence, plasmonic properties of the metallic nanostructure. A localized surface plasmon resonance sensor is an effective platform for biomarker detection. They offer a better bulk surface (local) sensitivity than a regular(More)
Mirizzi syndrome is the compressive blockage of the cystic or choledochal duct caused by a biliary stone occupying the cystic canal or Hartmann's pouch. This occurrence is rare and, in English literature, three cases defined in children have been observed. In order to draw attention to this rare occurrence, we preferred a 14-year-old male patient with(More)
Nanofabrication technology plays an important role in the performance of surface plasmonic devices such as extraordinary optical transmission (EOT) sensor. In this work, a double liftoff process was developed to fabricate a series of nanohole arrays of a hole diameter between 150 and 235 nm and a period of 500 nm in a 100-nm-thick gold film on a silica(More)
In this research, elementary school principals' instructional leadership behavior was evaluated based on the perceptions of elementary school teachers. The research is believed to contribute to the development of instructional leadership behavior of elementary school principals for the development of school organization. A " semi-structured interview(More)
A new micromanipulation technique is demonstrated using magnetic levitation. Millimeter-size microrobots are levitated and controlled in a volume of 3 x 3 x 2 em", A photo-thermal SU-8 microgripper was attached to the microrobot for manipulation operations. The motion of the microrobot is tested for automatic and manual trajectories and an rms accuracy of(More)
