The University of Texas at Arlington is pleased to host the 1st International Symposium on Traumatic Brain Injury – Mechanisms and Protections on April 11, 2019. The specific objectives of the symposium are to (i) share state-of-the-art research on TBI mechanism and protection, (ii) foster greater research collaboration across disciplines, sectors, initiatives and countries and promote interactions between the TBI research community with the veteran community, contact sports community and others for education and outreach, (iii) identify knowledge gap on TBI re

3D printing or Additive Manufacturing (AM) technologies carry the promise of revolutionizing the quality and efficiency of healthcare. However, the required technologies, even when available, are currently too fragmented to be integrated into routine, affordable and streamlined solutions that can benefit a large number of patients. The challenge thereby is to deliver 3D printing technologies that enable:

We have two PhD positions starting in 8/2019 to work on Mechanics and Manufacturing of Programmable Materials. This project intends to develop new methodology to design and fabricate materials/structures that exhibit programmable morphology and/or properties under external stimuli. 

Position 1:  The student is expected to conduct experimental research on programmable materials such as material preparation, 3D/4D printing, hybrid manufacturing, material and structure testing, etc.;

Openings are available for PhD. students in the Nanomechanical MUltiphysicals lab at UT-Dallas, with a start date of August 2019. Outstanding candidates may be considered for starting in May 2019.

The Department of Mechanical Engineering at the University of South Carolina is expanding its research portfolio to metal Additive Manufacturing. Two PhD positions are available in the Additive Manufacturing Lab led by Dr. Lang Yuan. Dr. Yuan’s research focuses on the fundamental understanding and prediction of microstructure and defect formation of metallic alloys during solidification processes.

Ghent University (Belgium) has three open PhD positions of each 4 years on ultrasound inspection of layered materials, ranging from composites over coated pipelines to wood. More information can be found on http://www.composites.ugent.be/PhD_job_vacancies_PhD_job_positions_compo....

Abstract

Hello, World

Here is a document that jots down, in a brief, point-wise manner, the elements of my new approach to understanding quantum mechanics.

Please note that the writing is very much at a preliminary stage. It is very much a work in progress. However, it does jot down many essential ideas.

I am uploading the document at iMechanica just to have an externally verifiable time-stamp to it. Further versions will also be posted at this thread.
