How to select an ideal location for installation of Solar Cooker ? Solar Cooker need Solar Energy to Cook your food. Identification of a location in your house where maximum sun light is available for maximum amount of time is require for efficiently using a Solar Cooker. Minimum of 2 to 3 hours of sunlight is required to cook any food in a cooker. Not only sun light, but the place must also be free of pest/animals/birds as the cooker will remain there for a long time. Normally, a place in the East or Northeastern side of your house/tent is the most suitable place for cooking food with solar cooker.

Any paper copy of maps can be converted into a digital map displaying real-time data with the help of GIS software. Here point shapefile is used to represent placemarks whereas line shapefile is applied for depicting roads, pipelines, etc. and polyline or polygon shapefiles are used for the representation of the area. All the shapefile is connected to the attribute table which in turn converts the map into an interactive data-driven representation of the paper copy of the sitemap. Below is the slideshow : You may also see my presentation on Terminologies of GIS to know about the definition of shapefile and attribute table.

Group Method of Data Handling(GMDH) is an algorithm that aids in the development and training of polynomial neural network (PNN)-based predictive models. PNN models have the advantage of being able to self-select the number of inputs and topology required to optimally and reliably learn the presented problem. In optimization problems, the Group Method of Data Handling, or GMDH, can be used as an optimization technique. Because the method is fast, non-parametric, and cognitive, the identification of the optimal point will be faster, and the result will be more reliable than that of non-linear or simple neural network models. A tutorial is created to describe how to use GMDH in optimization problems with the help of the GMDH Shell software. Find the full tutorial given below: Happy optimizing.
