The document summarizes a smart water meter trial conducted in Perth, Australia that tested how real-time water use monitoring and online feedback could be integrated into an existing water conservation program. Nine households participated by having smart meters installed that collected water usage data and sent it to an online dashboard. While engagement with the dashboard was lower than expected, most households reduced their water usage. Feedback from participants was initially positive about using the dashboard to monitor and compete around water usage. Lessons learned include better understanding meter limitations, carefully designing visual data displays and analysis, integrating smart meter data into eco-coaching, and fully combining smart metering with community-based social marketing programs.

What are the latest developments in the highly charged world of electric energy-efficiency technologies? Get updates on current advancements in LED lighting, air conditioning, non-intrusive monitoring, and more
Reducing rural poverty and improving household nutrition are common goals across all developing countries in the
Asia and Pacific region. To this end, the region has experienced a recent resurgence in large investments in irrigation
infrastructure. This surge in funding flows has created pressure from donors and central financing agencies, both of
which are increasingly demanding more robust justification for the investments. To date, providing this justification for
irrigation investments has been challenging due to a lack of reliable longitudinal data that measure the performance of
irrigated agriculture and associated water delivery services. Consequently, there is very little information on the real
returns on investments already made. Historic data has tended to be project based, point-in-time data constrained to a
defined area of infrastructure investment, not on-going and geographically broad-based.
Irrigation benchmarking is a process of comparative analysis of irrigation performance that enables scheme managers
to understand the performance of their irrigation services (International Water Management Institute, 2019). To better
understand the process of monitoring irrigation performance, this brief will use Cambodia as an illustrative example.
Irrigated rice production in Cambodia has significant potential, yet performance of the sector lags behind surrounding
countries, such as Viet Nam’s delta region (Mainuddin and Kirby, 2009). In addition, there are limited available and
published data in Cambodia, making it difficult to analyse the current and changing state of irrigation in the country,
the productivity levels, or irrigation’s contribution to poverty alleviation and economic growth (Tucker et al., 2020). For
these reasons, Cambodia was selected as a country to pilot the transfer of key learnings from the Australian experience
of irrigation performance benchmarking, and to develop a benchmarking methodology as a first step to undertake
ongoing performance assessment of irrigation schemes for strategic investments in increasing water productivity.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

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).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
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.

27. Participating Households
• Selection criteria,
• Selected participants offered meters.
• 9 households accepted the offer
• Pulse head and data logger also installed at Josh
Byrne family home, ABC TV’s Gardening Australia.
27
28. Results: Engagement
Engagement with dashboard lower than expected;
• Letter & info packs sent as physical reminder of
smart meter challenge (Round 4).
• Phone calls to prompt dashboard use (Rounds 4
and 5).
• Letter insert in response to participants
forgetting log-in details/or not logged on to their
dashboards (Round 5).
28
29. Results: Data Analysis
• Heat Maps - help identify anomalies &
patterns of water use.
• Weekly Profile Comparison Reports -
water use averages & maximums
tabulated & graphed for 2 periods of
time.
• Nature of this program means water
reduction cannot be solely attributable to
real-time data through online dashboard.
29
30. Results - Water Savings
Most households made a water savings!
Note: Season effect on consumption - large decrease in consumption
coincides with winter & not direct result of smart meter installation.
30
31. Participant Feedback
Initial feedback encouraging:
“We have been using the dashboard for just over a week now and
have been checking the dashboard on a daily basis. Seeing how
we compare to other households is very motivating. When we first
logged in we were above the average now we are below and trying
to get lower - I don't know how they can use so little water - if you
have some insights please pass it on!.
My partner has become very competitive about what we are calling
the "Shower Peaks" on the graph; he is trying to use less water
than me for each shower. When we first started I used considerably
less water than him for showers now we are about even. So I think
this Greensense meter has really helped him monitor his water
usage because where I always think about my water usage he
never did so it really has improved his water usage.”
31
32. Lessons for the future
• Understanding meter limitations
• Visual display of real-time data
& analysis for households must
be used carefully.
• Effort required for successful
engagement
• Carefully integrate the
dashboard & data into eco-
coaching
• Future programs can fully
integrate smart metering with a
CBSM BCP
