This document outlines the targets for a research project on developing a polarizer for hyperpolarized xenon MRI from January 2012 to June 2013. The targets include:
1. Designing, developing, and testing a cryogenic accumulator for spin polarized Xenon-129.
2. Designing, fabricating, and testing a magnetic yoke to generate a magnetic holding field for cryogenically accumulated polarized Xenon-129.
3. Designing and building a breadboard optical polarizer based on different conceptualized optical schemes.
4. Designing, fabricating, and testing a gas flow control unit.
Finite Element Analysis of Solar impulse aircraftAdarsh Agrawal
The presentation discussed about the Finite Element Analysis that was done on the famous solar impulse aircraft which was one of those projects that was funded by Google. The presentation includes information about the project and how the aircraft came into being.
Authors: Adarsh Agrawal, Gunjan Javaria and Vaibhav Mahawar
This presentation was made in PowerPoint 2010 as a vignette to open an orthodontic event in Rio. You can view the animated version on youtube - http://www.youtube.com/watch?v=6etYcVqcyjQ

ProSIM has been providing engineering design, and R&D services to OEMs, Operators, EPC contractors, System Integrators and vendors of nuclear power sector. ProSIM has assisted in the design and seismic evaluation/ analysis of systems, structures and components (SSCs) of nuclear power plants (NPP). Driven by its competence and focus on quality and project management processes, ProSIM has delivered value to its customers. ProSIM has interacted with regulatory bodies and code committees related to nuclear design codes. Methodologies for seismic analysis of mechanical equipment (rotary and static), electrical engineering, instrumentation and control, and structures have been developed by ProSIM using ASME boiler and pressure vessel (B&PV), RCC, IEEE, ASCE and similar codes. Several hundreds of reports of seismic analysis/ evaluation submitted by ProSIM have been approved by the operators or regulatory bodies. ProSIM has taken up several detailed engineering projects. Worked on design optimisation of structures/ equipment, pipelines, supports etc. ProSIM has also supported seismic qualification of equipment/ systems by physical testing by coordinating with agencies.
In addition to the seismic analysis during engineering stage for structural integrity assessment, ProSIM has worked on seismic margin assessment, seismic re-evaluation, fitness for service (FFS), remaining life assessment and extension (RLA/RLE), and failure analysis.
