Water Saving Retrofit Device for Squatting Pan Without Trap

low energy rotary nozzle: an energy and water saving device for field crop irrigation

pressurized irrigation technologies of course have the potential to raise the productivity of land and water; but, these technologies could not popularize among the smallholders who own millions of farms worldwide. in developing pressurized irrigation technologies, particularly for field crops irrigation, researchers and manufacturers have developed more specialized and expensive technologies w...

Power-Assisted Liposuction (P.A.L.) Fat Harvesting for Lipofilling: The Trap Device

Retrofit of Water Network with Regeneration Using Water Pinch Analysis

This paper presents the development of a new systematic technique for the retrofit of water network with regeneration based on water pinch analysis. The procedure consists of two parts: retrofit targeting and design for a water network with regeneration unit(s). In the targeting stage, retrofit targets (utility savings and capital investment) were determined for a range of process parameters (t...

Retrofit of Water Networks in Process Plants

In this paper, we present a methodology for the retrofit of water utilization systems using mathematical optimization. The problem consists of determining the best re-piping and the capacity of a new treatment unit (if any) to be introduced to generate the best retrofit. Instead of reducing water consumption, or maximizing savings, we resort to analyze the problem using a more comprehensive vie...

Dynamic PAN-Based Virtual Device

In this paper we introduce a novel concept, which considers all the autonomous devices on the user 's Personal Area Network (PAN) as one big "Virtual Device" having multiple input and output units and providing a coherent and surround interface to the user. Such a concept is quite valuable to the user since it allows him to manage all his devices as one. The paper also proposes and describes a ...
