I am writing a book about latest trends in humanoid robot development. I do have a diverse technical background in electrical, mechanical and software engineering but maybe not so much in book writing. This is my first attempt. I have completed a few chapters (about 20,000 words) and need editing, expanding paragraphs (to 40,000 words) and balancing overall book structure. I will provide a technical content and ideas. Still, this work will require some degree of technical knowledge and interest in robotic development field. In other hand, I would like to have a broad audience by isolating a technical details from general description.

I'm working on a new medical device concept and need some help with some basic thermodynamics calculations. I need help with the following: How much current is required to cool a given volume of heart muscle tissue (myocardium) by 5 degrees Celcuis using a peltier cooling chip (  [obscured]  /wiki/Thermoelectric_cooling)? Here a couple other details: Peltier cooling chip will only be on one side of volume of myocardium tissue Tissue dimensions are 6 cm x 5 cm x 2 cm. Cooling should be completed in 20-30 seconds If you think you can help with these calculations, let me know. You will need to research the constants for myocardium.

The attached sketch of a floor plan is the existing, 1,755 square foot, layout of a 1975 ranch house with a~300 sf basement (which is not yet dimensioned but should be added on 7/10-7/11). We are moving a family of 2 adults and 4 children, 6 and under, into this house. Our plan is to enclose the garage to make it into a master bedroom and bathroom (see the adjoining bathroom to the garage), and expand the kitchen into this area, allowing for a kitchen upgrade. A stair case will be added to access the basement from inside the house. We would like to add a garage or detached garage/carport once the garage is closed in, so that cars can still be parked in a covered area. Requirements: 1 - The existing floor plan shall be transferred to a suitable architectural, digital 3d model style (Chief Architect, Arch CAD, etc) so we can get a better feel for what the current house looks like from all angles. 2 - The floor plan shall be modified to accommodate the enclosure of the garage and b...

The project is for a small consumer product that will use motion control to activate a light. The heart of the project is a Printed Circuit Board with a Microcontroller (MCU) and an Accelerometer (ACCEL). The device will need to be configured to run on the lowest power possible, with the device going into low power, or sleep mode in-between each MCU cycle. The device will run on 3V power using a re-chargeable Lithium Ion battery. The PCB will need a charging circuit, a low voltage cutoff circuit, a USB plugin connector that can communicate to the MCU and recharge the battery. The electrical engineering requirements are as follows: -Finalize decision on which MCU to use (current proposed MCU is PIC24FJ64GB002) -Design charging circuit and low voltage cutoff circuit -Capture and layout PCB with, charging circuit, low voltage cutoff circuit, Micro USB connector, low battery LED, power connection, mode switching button, necessary load switching circuits, and connection to an on / of...

I need an electrical component designed for a project I am working on. The project is 2 ft by 2 ft tiles that will be attached to a ceiling or wall and allow for me to make an LED star system that can be expanded or reduced by connecting or removing tiles. The tiles will need to use LED lights and fiber optic cables that are fed through preformed holes in the tiles and plug into a standard US outlet or an a joining tile. I also would like to create a twinkle effect with some of the cables. I have attached some preliminary drawings of what the tiles will look like.

Would like a design for an SSPA of at least 30 db gain, which will produce 1KW at 1.3 GHz. Linearity not an issue, but output power must monotonically increase with drive (no oscillations or spurs). 5% bandwidth is sufficient. Cost of first prototype should be separated out. Design will eventually have to be power combined later, so power combining experience is a plus.

The grid was projected without any line until now however these lines should be installed later. The wind generator is based on the power_wind_dfig model and this block was extracted from the mathworks library. My very end purpose is to prove that the load frequency is much more stable with a storage solution (FESS or BESS) (49,95% until 50,1%). If necessary you can change the parameters of the model as you wish, or even change the models of the generators if necessary. I sent you some papers with the approach i want to implement in my model. I also sent you some information about the island grid itself. One of the articles, that I considered the main one, talks about a study that was made in the island I am studying. The study concludes about the instalation or not of storage solutions on the grid "Main Article - Porto Santo". Problem In small isolated power systems, such as those existing in certain small islands, the presence of 2 or 3 wind turbines creates a large inter...
