    Design and integration of a bimorph thermal microactuator with electrostatically actuated microtweezers
    (Institute of Electrical and Electronics Engineers (IEEE), 2008) Yilmaz, Mehmet; Yalcinkaya, Arda D.; Leblebici, Yusuf; Zervas, Michalis; Department of Mechanical Engineering; Alaca, Burhanettin Erdem; Faculty Member; Department of Mechanical Engineering; Koç University Surface Science and Technology Center (KUYTAM) / Koç Üniversitesi Yüzey Teknolojileri Araştirmalari Merkezi (KUYTAM); College of Engineering; 115108
    A multi-digit gripper is proposed that consists of two electrostatically actuated end-effectors operating in the plane of the device and three thermal end-effectors operating out of plane. The integration of thermal and electrostatic actuation mechanisms is realized by using a three-mask monolithic process. First mask is used to define the silicon electrostatic actuator on SOI wafer. Second mask is used to obtain the bimorph thermal microactuator made of polyimide and aluminum layers on top of the electrostatic actuator. Third and the final mask is used to release the integrated electrostatic and thermal microactuators.

    Online optimization of first-responder routes in disaster response logistics
    (IBM, 2020) N/A; Department of Industrial Engineering; Shiri, Davood; Salman, Fatma Sibel; PhD Student; Faculty Member; Department of Industrial Engineering; Graduate School of Sciences and Engineering; College of Engineering; N/A; 178838
    After a disaster, first responders should reach critical locations in the disaster-affected region in the shortest time. However, road network edges can be damaged or blocked by debris. Since response time is crucial, relief operations may start before knowing which edges are blocked. A blocked edge is revealed online when it is visited at one o f its end-nodes. Multiple first-responder teams, who can communicate the blockage information, gather initially at an origin node and are assigned to target destinations (nodes) in the disaster-affected area. We consider multiple teams assigned to one destination. The objective is to find an online travel plan such that at least one of the teams finds a route from the origin to the destination in minimum time. This problem is known as the online multi-agent Canadian traveler problem. We develop an effective online heuristic policy and test it on real city road networks as well as randomly generated networks leading to instances with multiple blockages. We compare the performance of the online strategy with the offline optimum and obtain an average competitive ratio of 1.164 over 70,100 instances with varying parameter values.
