The Role of Thermal Potential in Enhancing Energy ProductivityYale Carden
As presented at All Energy Conference in Melbourne on 5 October 2016
In the renewable energy sector, electrical (energy) potential determines the design of renewable power systems (ie solar, wind etc) at any given location. Similarly, thermal (energy) potential relates to the available thermal energy in a given location that can be utilised for heating / cooling a building or group of buildings.
This presentation explores how the concept of thermal potential can increase the efficiency of heating / cooling systems and thus enhance energy productivity in terms of increased value output per kW generated and per tonne of carbon emitted.
Thermal Potential in the Built EnvironmentYale Carden
HVAC systems have traditionally used the local ambient air (heating and cooling) or fossil fuels (predominantly heating through combustion) as their heat source and heat sink. Thermal storage is still a relatively new application and typically requires large volumes of water or ice.
This paper explores the available thermal potential within the built environment and how the utilisation of this thermal potential can provide efficient heating, cooling and hot water as well as thermal storage. In some instances, this may be the local ambient air, less likely it will be fossil fuels.
More likely, it includes the thermal potential within the ground, water bodies and infrastructure such as subways, water, sewer, building foundations and other buildings as well as artificial thermal storage such as phase change materials.
The key is to identify the optimal thermal sources, sinks and storages for a given building at a given location and climate. Then, an integrated approach using optimised control strategies, including predictive capabilities, will enable a building to access these various thermal sources at the thermally optimal time to provide significant energy savings and enhanced operation.
Such an integrated approach also maximises the availability of on-site renewable power generation, further increasing energy savings, decreasing the typical cooling peak demand and increasing energy productivity.
Using the Ground for Thermal Energy Storage: The Experience of the Riverina H...Yale Carden
All buildings interact with the ground for its ability to support their foundations. However, very few buildings interact with the ground for its ability to provide thermal energy storage. We have all experienced the moderate temperatures within a cave at depths of just a few metres. These temperatures are a function of average annual air temperature and are the result of the ground absorbing and storing solar energy. The use of this indirect and renewable solar energy can provide significant energy savings for heating and cooling systems.
A Ground Heat Exchanger (GHX) provides the ability to utilise the ground for thermal energy storage, essentially transforming the ground into a thermal battery. It enables us to extract heat from it in winter (heat source) and return that heat in summer (heat sink). It is a dynamic thermal battery that operates both simultaneously and over the annual heating / cooling cycle.
This presentation will provide an overview of how the ground is being utilised for its thermal energy storage capabilities around the world, with focus on a local installation at the Tumut Council owned Riverina Highlands Building, located in Tumut NSW. The installation has provided Council with energy savings on heating and cooling of 80 %, reduced peak energy loads by 40%, reduced maintenance costs and, importantly, provided significantly higher levels of occupant comfort. This has also increased the capacity and effectiveness of the concurrently installed solar PV array and will ensure that future solar energy storage will have greater impact.

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.

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).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

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.

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!
