Rain Water Harvesting And Artificial Recharge Of Groundwaterpartha sharma
Water harvesting can be traced back through human history almost as far as the origins of agriculture. Water harvesting is defined as the redirection and productive use of rainfall.
A wetland is a land area that is saturated with water , either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem .
The primary factor that distinguishes wetlands from other
land forms or water bodies is the characteristic vegetation of aquatic plants , adapted to the unique hydric soil.

Polyvinylidene Fluoride PiezoelectricFilm (PVDF) is a relatively new class of piezo-electric device.PVDF material is a thin plastic polymersheet with its molecules aligned in auniform pattern. It has a electrically conductive coating deposited on each side of the sheet.
The Low Impact Development Site Planner is a web hosted tool that enables the use to quickly assess the feasibility of specific stormwater mitigation approaches including green infrastructure and conventional treatment systems. This presentation describes the architecture of the program and demonstrates its use on a typical project.
With rising crude prices and depleting quality of crude, however, the level of wastewater pollutants in petroleum wastewater is at new high. Such conditions are forcing refineries to use a more advanced water treatment, water recovery methods, and robust processes that work well under a variety of conditions and can handle the changing refinery effluent flow rates. Finally a process that is economical in overall life time cost is needed to make all of this feasible. Aquatech has experience working with these refinery effluent pollutants in the refinery market and offers the advanced petroleum wastewater treatment and recovery technology necessary for the refinery’s needs.
In July of 2011, a denitrifying bioreactor was installed in the Hewitt Creek watershed in northeast Iowa. A denitrifying bioreactor is installed to reduce nitrate delivery from agriculture fields.

Have you ever wanted a Ruby client API to communicate with your web service? Smithy is a protocol-agnostic language for defining services and SDKs. Smithy Ruby is an implementation of Smithy that generates a Ruby SDK using a Smithy model. In this talk, we will explore Smithy and Smithy Ruby to learn how to generate custom feature-rich SDKs that can communicate with any web service, such as a Rails JSON API.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
