I have a client that is developing a model for natural gas distribution and wants to analyze its impact on Greenhouse Gas Emissions. The table below projects estimated natural gas consumption volumes over a 25 year project. We are looking for an analysis of the anticipated impact in terms of greenhouse gases and overall climate change assuming that this natural gas displaces a combination of bunker crude and diesel fuel. The impact should be modeled at the following percentages 0% diesel / 100% bunker crude 25% diesel / 75% bunker crude 50% diesel / 50% bunker crude 75% diesel / 25% bunker crude 100% diesel / 0% bunker crude Natural Gas Volume in Year MMBtu 1 18,000,000 2 21,600,000 3 25,920,000 4 31,104,000 5 37,324,800 6 44,789,760 7 53,747,712 8 64,497,254 9 77,396,705 10 92,876,046 11 111,451,255 12 133,741,506 13 160,489,807 14 192,587,769 15 231,105,323 16 277,326,387 17 332,791,665 18 399,349,998 19 479,219,997 20 575,063,997 21 690,076,796 22 828,092,155 23 993,710,586...

I am looking for an electrical engineer to design and layout two PCB's for a wireless mic and Receiver. Both sides utilize the same module, it is configured on the board layout as transmitter or receiver. Board files must be created in Altium so that our engineer may review as we achieve milestones.

I am conducting a feasibility analysis to bring an inexpensive wearable fitness device (fitband) to market. The product I am interested in manufacturing is nearly identical to the MOOV fitband:   [obscured]  /us/moov-fitness-tracker-app-watch,review-2414.html The device I envision would require: 1) Motion Tracking: Invensense MPU-9150 (or MPU-6050) 2) CPU: Atmel ATmega32 or TI device used in Invense reference designs 3)Bluetooth 4.0: Nordic nRF8001 BLE 4)lipo battery with Microchip MCP73831 charging circuit (micro usb charge) battery life only needs to be around 3 hours since the focus will be intense sports and exercise. 5)Is a a volume manufactured cost of <$20 per unit possible? 6)dimensions roughly equal to ipod nano 6th generation (is there an existing case mold that could be leveraged?) No wristband would be required, just a square circuit board in a basic slim plastic case that could fit into a silicone band such as the ipod nano band (6th generation):   [obscured]

We like to build a prototype product using fiber optics and by utilizing its highly sensitive micro bend multimode fiber optic sensor for simultaneous measurement of Breathing rate and Heart rate. It will be based on the technology developed by some of industry's current products. We have some published journals and utility patents information. And the we already had the design concept approved by several fiber optic expert. The right candidate need to review our design concept first,and working with us starting from scratch.The Target is to provide us a functional prototype(once the design complete we will have our in house technician build the prototype). The Key skills we looking for are: 1.Fiber optic expert:able to help has find right Fiber optic cable and associate fiber optic components. 2.Material engineer knowledge. 3.PCB design:PCB Design/Develop will be involved in this project. Firmware skills will be a plus. Labview experience will be a plus Wireless Design experience ...
