This document discusses sustainable water management strategies for mine closure. It outlines a conceptual model and protocol for assessing water quality and balances at mine sites over their lifecycle from exploration to closure. Key aspects include developing hydrological and lake conceptual models, quantifying water quality evolution, scenario testing, field data collection, water quality modelling, and validation. The goal is to predict pit lake water quality and identify options to achieve beneficial end uses or acceptable environmental impacts at minimum cost. A multi-disciplinary team applies several tools and considers factors like geochemistry, meteorology, and ecology.
This presentation describes the current scenario of mine closing in India, a comparative study with other developed countries like Australia, Canada etc. and GIS based approach for proper execution according to the existing topographical conditions. It's an unconventional approach and having broad scopes to be enhanced in future.
A presentation on Reclamation examples associated with historic copper mining operations. Rosemont Copper gave this presentation to the Forest Service and their contractors during a meeting in May 2010.
Dampak yang nyata dari suatu proses penambangan adalah bentang alam yg cenderung berubah. Sejalan dengan perubahan kondisi alam serta kerusakan yang diakibatkan oleh proses penambangan, maka perusahaan sebagai penanggungjawab bertanggungjawab untuk mereklamasi lahan bekas tambang tersebut sesuai dengan peruntutannnya. Supaya habitat di sekitar lokasi itu bisa kembali normal walaupun tidak sepeti sedia kala.

RINA - AOG 2017 - Ian Milne - River LAB Wave BasinNick Bentley
RiverLab involves a community of more than 15 researchers working on projects spanning across oceanography, engineering and animal biology. One of the capstone projects involves the design and construction of a model FPSO, in combination with a novel instrument system to measure the vessel heading and dynamic motion when subjected to natural and artificial waves in the river. The innovations in this capstone project are the use of low cost sensors in combination with the Swan River rather than a traditional wave basin. Basins offer user-specified sea states, but the waves are often long crested and include unavoidable reflections due to the walls of the basin. Data obtained through this capstone project will be used to better understand FPSO motions in directionally spread waves and to validate numerical models of vessel motions - leading to improved models for prototype predictions.
This talk was given for Saudi Company Maaden. Different idea why uncertainty quantification in geology, mine business, reservoir description is important.

Looking to the past to understand the future
To understand fully the future direction of the oil and gas sector here in WA, it is important to consider and recognise the recent history and current challenges being experienced. This history and current challenges formed the first section of the presentation highlighting the scale of expansion of the industry here over the past decade, where we have moved from around 20mtpa LNG to a anticipated output level of some 50mtpa in WA alone, which, when combined with the additional capacity being constructed in QLD and NT will make Australia the world’s largest exporter of LNG by the end of this decade.

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.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.

Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Builder.ai Founder Sachin Dev Duggal's Strategic Approach to Create an Innova...Ramesh Iyer
In today's fast-changing business world, Companies that adapt and embrace new ideas often need help to keep up with the competition. However, fostering a culture of innovation takes much work. It takes vision, leadership and willingness to take risks in the right proportion. Sachin Dev Duggal, co-founder of Builder.ai, has perfected the art of this balance, creating a company culture where creativity and growth are nurtured at each stage.
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.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
