    For a smarthome solution (control lights and wall outlets at home), some port forwarding has to be defined (and deleted) in order to get access to the smarthome gateway from underway (remote access). The desired application have to meet the following criteria:- Launch without prior installation (if possible)- After startup search for smarthome Gateway (via UPnP Device name) and displaying the result ("Your Smarthome gateway was found at IP address: x x x x")- Search for the standard Internet Gateway (router) and check, wether the port forwarding is enabled or not. Check if UPnP is enabled, if not, a message has to be displayed.- Display of some describing text and alle the found info (IP-addresses)- Providing an On/Off-slider to turn the port fowarding on or off.- If succesfull, display a "done..." Message and software ends.If you are interested in this project, please send me references for your software. Must not be from this technical sector, but I want to get an impression of the GUI. ThanksPeter

    I need a software, Windows and Mac(desirable) platform, to recognize pre registered people in jpeg high resolution pictures.The software just have to recognize only registered people ignoring all others.All the pictures will have very good quality, colors and resolution and if the system recognize one or more people, the informations will be write in a database or in the picture metadata (XMP Technology).The user interface should be like the Picasa facial recognition feature (annexed picture). Picasa is so close for my needs, but I don´t use it because it tries to recognize everybody and I just want recognize registered people.The minimum recognition accuracy acceptable is 85% because all the pictures have very good resolution.When the software are in doubt between two or more registered people, it will show for the operator choose the correct one.It´s indispensable the job with the source code and documentation for future integration with another software that I"m developing.

    Develop a program that converts an image to height contours which are then solved to form a contiguous 3d object which reproduces the image from projected caustics when illuminated by a parallel light source. The resulting 3d object must be compatible with CNC fabrication techniques. The program must use light transport calculations to calculate the surface normals necessary to reproduce the target image, and then convert these normals to a height field to give the necessary surface contours to be manufactured in a transparent plastic.The first challenge is solving an inverse problem to the one posited in the standard law of refraction. Rather than determining the caustic patterns caused by light interacting with a transparent medium, the caustic patterns must correspond to a target image, with the surface contours of the medium as the variable to be calculated. The second and more challenging part of the problem is solving and optimising the resulting data to produce a coherent and manufacturable 3d shape. This is where a familiarity with 3d geometry and debugging will be essential. Once a coherent solid shape has been generated we will run it through light simulations in 3DSMax and V-ray or an equivalent program to confirm its functionality. If these tests are successful, and if the applicant is interested, we can begin to experiment with re-introducing some more organic caustic elements. It is in this respect that this project will differ from similar techniques for calculating caustics previously developed by researchers at UCL and EPFL. The end goal of the project is to allow figurative and random elements to co-exist in the resulting caustic image. Rather than aiming for verbatim image reproduction, the aim is to control the manner in which natural patterns and representative form can co-exist and interact. Alternatively the job can end once a functioning and manufacturable 3d shape has been confirmed as producing the desired image. The following papers outline the technical process used in similar work, and should be read in order to get an understanding the level of maths required:http://lgg.epfl.ch/caustics/documents/caustic_art.pdfhttp://lgg.epfl.ch/caustics/documents/gpd13_3d_02_pauly_controlling-caustics.pdfhttp://www.uni-ulm.de/fileadmin/website_uni_ulm/iui.inst.100/institut/mitarbeiter/holger/causticRecon.pdf

    We are seeking a good developer (s) to develop a fast to use streamlined database application. This is to assist in the good purchased process within our IT Company that currently makes use of a single spreadsheet. Each purchase we make of goods is entered into a spreadsheet.That data later gets imported into our accounting application Sage.So the fact it’s just currently one spreadsheet that we are turning into a database, should make it a straight forward project for anyone with relevant skills. The database may grow on to include many other features that support our internal business process and in some regards, this project is a test project for us to develop a relationship with developer(s).Initially we had strong ideas about the development / coding platform that should be used, even considering Access at one time because of the UI speed it can give (As we are from a coding background), but now we are open to anything that can give, good interface performance, is scalable (we have big ambitions) and is able to developed and well documented The attached document outlines the project in greater detail.
