Owing to the growing global environmental problems, demands for environmentally friendly, fully biodegradable sustainable composites have substantially increased across various industries. Inspired by the composite structure of cocoon silk, we fabricated a fully green composite fiber (GCF) that is based on the lotus fiber (LF) and a biodegradable polymer, namely poly(vinyl alcohol) (PVA). After...

Cyclist detection is an important task for automobile industries. In this paper we present a vision based system for cyclist detection. We build cascade detectors for cyclists in different viewpoints and part filters to deal with partial occlusions. To improve the performance, geometry based ROI extraction method is integrated. Additionally, a Kalman filter in combination with optical flow is a...

Integrating sensors with autonomously navigating robots makes them useful for many applications: delivery of packages, components, and supplies; monitoring wireless networks, radiation, or HVAC; and responding to emergencies and hazards. MobileRobots' intelligent, autonomous mobile platforms perform these and many other tasks. A result of nearly eleven years of development, the company's next-g...

The need for fuel efficiency and increased performance in transportation systems continually places new demands on the materials used. The design criteria which automobile and aerospace industries are primarily concerned with are density, strength, stiffness, and corrosion resistance. Low-density materials may reduce fuel costs, increase range, and allow larger payloads. High strength and stiff...

With the increasingly development of automobile, electronics, aviation, spaceflight and other industries, it has put forward higher and higher requirements on the quality of molybdenum powder metallurgy products. Therefore, it is required that molybdenum powder should have better performance in chemical composition, physical morphology, average particle size, particle size distribution, apparen...

This paper attempts to examine the international competitiveness of the Turkish automobile industry within the context of Porter's (1990) diamond framework which covers four principal determinants of competitiveness namely factor conditions, demand conditions, related and supporting industries, and firm strategy and rivalry. This analysis also provides explanations on the industry's changing ro...
