The problem of consciousness should eventually receive a scientific solution, but there are a number of scientific and philosophical obstacles along the way. I offer solutions to the philosophical problems and proposals for approaching the scientific problems.

The concept of topological sensitivity has been successfully employed as an imaging tool to obtain the correct initial topology and preliminary geometry of hidden obstacles for a variety of inverse scattering problems. In this paper, we extend these ideas to acoustic scattering involving transient waveforms and penetrable obstacles. Through a boundary integral equation framework, we present a d...

the importance and various applications of information technology have made fundamental changes in all organizations. the aim of the present study was to identify and prioritize the obstacles to the application of information technology in sport and youth offices using fuzzy topsis technique. the study had an application purpose and used a descriptive-survey methodology and data were collected ...

Today, there are increasingly more powerful many-core processors (MCPs) that are integrated into stationary and mobile devices, freely programmable and well suited for multimedia processing. However, there are still many obstacles and problems when programming multimedia applications for MCPs. In this paper we show that all these obstacles and problems can be solved by treating a device with an...

We consider the time-harmonic elastic wave scattering from a general (possibly anisotropic) inhomogeneous medium with an embedded impenetrable obstacle. show that obstacle can be effectively approximated by isotropic particular choice of material parameters. derive sharp estimates to rigorously verify such effective approximation. Our study is strongly motivated related studies two challenging ...

In structured prediction problems where we have indirect supervision of the output, maximum marginal likelihood faces two computational obstacles: non-convexity of the objective and intractability of even a single gradient computation. In this paper, we bypass both obstacles for a class of what we call linear indirectly-supervised problems. Our approach is simple: we solve a linear system to es...
