I am looking for an engineer that can design a high torque worm drive rack using a battery powered motor. This product will be used in the sea at depth and needs to be very robust and durable. Project details can be made available once an nda is signed. Happy to pay an hourly rate but would prefer to negotiate a fixed fee based on the full brief. Potential future projects as well.

We need a design/component that will allow us make two connections from a PCB to an antenna that are extremely close, but will never touch. More details: We are trying to implement a PIFA antenna on a very small scale Bluetooth device. See attached illustration. To accomplish this, we need to place the feed and shorting pin connection points as close to each other as possible. We need a manufacturable solution to connect the PCB to the antenna and ground to the antenna where these two connections points are between 0.6-1.6 mm apart from each other where they make contact with the antenna.

Efficient Finite Element methods for natural and mixed convection flows in deformable domains under thermal stresses.................Project Description We develop an efficient class of finite element methods for modelling deformation of domains in natural and mixed convection flows. At high temperature thermal stresses on the solid enclosures are expected to generate deformation on the domain confining the fluid flows which alter the flow structures. The aim of the study is to develop a consistent model for coupling convective flow, heat transfer and solid deformation in different enclosures. Coupling conditions at the interface between solid and fluid domains are also investigated in this study. Two types of flows are are considered in our work using the incompressible Navier-Stokes equations for the first type and the Darcy equations for the second type. Linear elastodynamics is used for the deformation of solids in our models. As a numerical solver we develop an efficient finite element method based on Glerkin-characteristics techniques in which same meshes are used for both fluid and solid domains. To speed up the numerical solvers we opt for two procedures: (i) mesh adaptation using a criteria based on the gradient of thermal stresses to refine the meshes and (ii) enrichment of basis functions using a series of heaviside and exponential functions in our finite element solutions. The performance of the proposed models and methods is explained and validated using several benchmark problems in natural and mixed convention flow..................my work is about simulation study on very hot fluid(air) flows over a solid, so thermal stresses are applied on the solid that can cause bending and deformation for the solid Navier-stokes equations , Finite element, Galerkin method .... all are used to sole the and do the study in Fortran90..............coding in Fortran..........I attached a pdf file which is close to what I am doing my simulation is on hot fluid (air) flows on a solid, that cause heat transfer and deformation ....... I need to mesh and use finite element method on both fluid which is air and solid of course I will use Navier stokes equations to study the behaviour of the fluid are you fimiliar with Navier-stokes equations??.........see this attached file it will help you understanding it

NOTE: WE ARE ONLY LOOKING FOR FREELANCERS IN THE SAN FRANCISCO BAY AREA. The full description for the job can be found in the attached PDF. Note that the budget posted here and the quote we are looking for is for having our current needs met. Those needs are to: incorporate control of pneumatic control valves into our current electronics box which is composed of a couple adafruit and sparkfun breakout boards with an Arduino; find and incorporate a way to sense the orientation of our device; and modify code so that we have better filtering of speed data coming from the truck, a stall feature that is suitable for the pneumatics system, and better user interface.

Electronics or Electrical engineers are to be hired who have strong report writing skills. If someone is good at mathematical calculations along with being a good report writer, he would definitely have a plus. A long term relation is expected during which the freelancer would be given multiple projects regularly. The short listed candidates would be given a small paid task which would be a step towards final selection. Regards mydesign
