Microstructure and fatigue crack growth behavior of heat-treated electron beam melted Ti-6Al-4V alloy
No full textThe effect of post-deposition heat treatment on microstructure and fatigue crack growth has been analyzed for electron beam melted Ti-6Al-4V plates. Samples have been heat-treated at temperatures of 950 °C and 1050 °C, and subsequently cooled at different cooling rates in the furnace and the water. The as-built sample possesses columnar prior β grains filled with exceptionally fine α+β Widmanstätten patterns and epitaxially grows in the vertical direction. Heat treatment with a slow cooling rate increases the α lath thickness, whereas fast cooling results in multiple needle-shaped α/α′ phases inside the prior β grains. The yield strength and ultimate tensile strength in as-built conditions are greater than the extruded mill annealed sample. The as-built samples show better crack growth resistance during the fatigue crack growth rate test than the heat-treated and mill-annealed samples. The lower plastic deformation of the as-built sample than the mill-annealed sample is attributed to the existence of fine α laths that restrict the motion of dislocation
Ideas for rent: an overview of markets for technology
No full textThis article surveys some of the recent literature on technology markets, and summarizes its main issues and insights. We structure our analysis in three parts: the supply and demand of technology; the factors that condition the formation and growth of technology markets; industry structure and dynamic issues. In addition, we summarize some of the studies that have tried to document the size and growth of these markets. We find that the literature has focused mainly on the supply of technology, but several other aspects of these markets remain under-studied, including the demand for external technology, the role of uncertainty in technology markets, and the dynamic interaction between industry structure and the market for technology. Understanding these will illuminate whether markets for technology will continue to grow or remained confined to pockets of the economy. Copyright 2010 The Author 2010.

Metrics for analytics and visualization of big data with applications to activity recognition
No full textActivity recognition systems detect the hidden actions of an agent from sensor measurements made on the agents' actions and the environmental conditions. For such systems, metrics are important for both performance evaluation and visualization purposes. In this thesis, such metrics are developed and illustrated. For human activity recognition datasets, a reporting structure is described to visualize the metrics in a systematic manner. The other contribution of this thesis is to describe a visualization tool for estimating the orientation (attitude) of a rigid body from streaming motion sensor (accelerometer and gyroscope) data. A feedback particle filter (FPF) is implemented algorithmically to solve the estimation problem.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-05-01The student, Rohan Arora, accepted the attached license on 2016-04-25 at 10:47.The student, Rohan Arora, submitted this Thesis for approval on 2016-04-25 at 10:48.This Thesis was approved for publication on 2016-04-27 at 15:05.DSpace SAF Submission Ingestion Package generated from Vireo submission #9459 on 2016-07-07 at 14:17:57Made available in DSpace on 2016-07-07T21:18:02Z (GMT).

New tool design for friction stir weilding of polymer
No full text"The FSW uses plastic deformation, generated through friction and deformational heating to join the workpiece. Therefore, the technique is very popular and well adopted in Automobile industry for joining of Aluminium sheets. The low frictional heat generation, low thermal conductivity and different solidification behavior of the thermoplastics, hinders the use of FSW for joining. The conventional FSW process in the thermoplastics gives poor weld strength, due to low frictional heat and poor thermal conductivity. A new tool design is proposed and tested for the Friction stir welding of polypropylene. The newly developed tool provided with a resistance-heating element inside the tool, resolves the low frictional heat problem in case of FSW of thermoplastic. The improvement in weld strength of the welded samples found to be more than double compared to conventional FSW weld. Microstructural analysis of the joints were done to see the effect of microstructure on the weld strength.
The tool heating, tool shoulder diameter, tool RPM and travel speed are important process parameters in FSW that affect the weld strength. The taguchi technique is used to optimize the process, by determining the relative effect of the the process parameters over the weld strength. The newly developed tool is promising for the industrial use, for joining of thermoplastics.
