We are looking for a mathematician or an engineer who would able to solve the following optimization problem. - The wood manufacturing business has X machines. Each of the machines is operated to process wood material during working hours. The number of working hours for each day of production should be an adjustable variable which can be changed by the user. - Every day the management of the business receive a list of jobs that need to be done during the next couple weeks (see attached); - Each job has a corresponding deadline that needs to be met; - Each job consists of X number of processes which correspond to each of the machines. Each process in a job needs to be completely finished before the next one can begin i.e. needs to run in order of Process 1 to Process X; - For each of the processes, there is a certain run time that is provided within the input data; - There should be an interval of 15 minutes between each job for any given machine. The goal is the find the most optima...

Hello, I wanted to know if you could help me. I'm designing a new product that needs an internal power generation. My research has steered me towards "disc type axial flux generators /motors". See attached sketch idea. Basically I need a test bed to prove theory I have based on the contrasts that are given. I can't fully describe the entire design but part of it needs to generate electricity and output it to a outlet, which kind of mimics a typical low voltage wall outlet performance you would find at a normal house. The initial device constraints was to have a cylinder can design with a max diameter of 3.5 -5 inches, and have the device be very light weight, and requiring very little force to spin the axial flux inside. I have not specified a height yet this is all a idea in testing phase. What I'm requesting is a design or instructions to create a test bed in my shop and so I can build and tested it, the shape and design are critical. This is a generator, I will ...

We are in early stage conceptual plan development for a 5 story wood frame 8 unit apart/condo building in Washington D.C. We are looking for an individual with 20+ years of construction management experience to consult with us on design/cost issues as we develop our conceptual designs and work with local permitting agencies. We have not identified a local GC yet and want to make sure we get good cost/strategic CG input from our consultant to guide us until we find a local GC. We would anticipate this team member could provide project scheduling (MS Project) schedules as well as develop our construction cost estimates etc. We have developed some preliminary conceptual designs and identified some issues requiring waivers for egress and a variance for parking. We are moving forward on filing for hearings on these matters and want to get some construction cost input in the interim so we can revise/update our conceptual plans while we wait for the two hearings. We would anticipate a...

My Research topic is:Two dimensional modelling of sand production, using Finite volume to solve the governing equation and then use C++ to program.A C++ Visual code would be used to solve a 2Dimensional Navier stoke's equation in order to predict the critical drawdown pressure. I have been able to obtain the governing equation and discretise using finite volume.I have been given a C++ Visual code of 2D Full Navier stokes equation comprising of the Energy equation,Momentum and Pressure Equation which i have to solve for a flow in a pipe and obtain the Temperature,U and V velocity, temperature distribution and then the pressure distribution in the pipe. I wish to check the functionality of the code by making it obtain the required result with the various boundary conditions imposed(Top and Bottom -Insulated, Left-Dirichlet, Right-Convective).After solving the Navier stoke's equation for the above problem , i would also need to incorporate the code to determine the critical drawdown press...

Hello All, I have an an app that I have written in Swift/Xcode, and I need it to run on an android platform. I have very little experience in the Android mobile development field, and do not want to spend time learning the ins and outs of Java in order to translate it. The app does rely on Parse as its backend database server, so one must be comfortable with working with it. There are also a few minor helper classes that are written in Swift, but I can provide those after an accepted work proposal. The app itself is not that big (7mb). So, if you have experience in the android field and have worked with the Parse framework, your help would greatly be appreciated! :)

Good Evening, I have a patent pending on a product that needs to be turned into a working prototype. The product is a fairly simple concept using a D battery for power source, a motion sensor (short range 180 degree spread x 14 inch range) operate a mini linear solenoid actuator or miniature push type plunger that would activate a pressure aerosol container. The elements will all need to be contained with-in a 1 3/4" x 2" x 15" plastic chaste. I see that you can produce drawings, will they be working drawings that can be sent to a manufacturer for pricing estimates (plastic mold). I have a contact that works with plastics in Philadelphia .. but have no source the other items needed except web based purchasing. In other words, how far can you take the product if we can agree on the design? Look forward to opening up a conversation if you are interested and able. Thank you in advance for your time.

I'm looking for an innovative chair back and armrest design. I'm creating a unique chair product and I need a backrest that can be height adjusted about 14" (7" higher and 7" lower from starting location.) The chair back is connected to a frame that also supports 2 arm rests (one on each side, obviously). The armrests also need to be height adjustable, approximately the same range as the backrest (about 14") but they need to be adjustable independently of the backrest. This is the general requirement, but I will send the winning proposals my drawings and complete details of the existing product so far so you can see what the constraints are, etc. I don't want to divulge too much yet, but I will provide the successful candidate(s) with complete information and everything you need. The goal is to find an easy solution to this problem, and one that isn't complicated to manufacture.

Parametric analysis of Solidworks flow simulation are to be carried-out using flow simulation API, the main idea is to edit already generated codes in VB 6.0 into VB.net or C++ (prefeably C++) , a plugin in terms of fluid codes (using codes already generated in C++ for navier-stokes momentum equation) should be embedded into the solidworks flow simulation environment), the VB 6 codes are able to do the following: 1. Change different impeller types used for the study 2. vary fluid height in the mixing vessel 3. Varying impeller rotational speed 4. Vary impeller distance from the bottom of the mixing vessel The plugin codes are written in C++, and its untended to be introduced into the mixing vessel as an external fluid and different results ar intended to be generated from the simulation that would determine which impeller gives better homogeneity and at what impeller distance this should be achieved.

Dear Bidders I will have 1 - 8 sets of plans a week, existing and proposed. And I need a contractor to use our excel calculator which will produce a quotation, you will need to go down the list of items in the calculator input the amount of material required and labour required to do the job. Its quite easy. You just need to know the amounts of materials required and the time to take to do the job. Each job will take a QS about an hour to do it. All prices are preset so you won't need to knowthe costs, just a mount of material and amount labour to do it. I am prepared to offer $25 per quote. There will be 1 - 8 quotes a week. I am based in the UK and am a director for my building company, the excel spreadsheet is copyright protected. Once you get in touch with me for a brief discussion I will then send you a sample quotation excel sheet you will be using. I have attached a sample set of plans which you would be using. I look forward to meeting you. Thanks Philip(ID: 77096...

Hello, I am trying to find a person to bring my product ideas to life and give them a real face and take them from sketches to a real look and design and then to real life. I have looked at other freelancers but no one works with soft goods (Materials) all just working with hard goods, electronics and solid designs. I saw your portfolio and was impressed and saw you back back designs so I figured Id reach out. I need a US base freelancer to make communication easier. I have three products I want to bring to life. I need a designer that can think outside the box, is creative and has the imagination to make this happen. Items: -Multi functioning sports towel/shell idea -caribiner key chain idea with multifuntioning hooks -folding top (similar to a jacket in shape) that can fold into itself
