The application of cooking gas refrigerants in refrigeration system is considered to be a potential way to improve energy efficiency and to encourage the use of environment-friendly refrigerants. Refrigeration operation has been met with many challenges as it deals with environmental impact, how it affects humans and how it contributes to the society in general. Domestic refrigerators annually consume several metric tons of traditional refrigerants, which contribute to very high Ozone Depletion Potential (ODP) and Global Warming Potential (GWP). The experiment conducted employs the use of two closely linked refrigerants, R600a (Isobutene) and cooking gas which is varied in an ideal refrigerant mixture of 150 g of refrigerant and 15 ml of lubricating oil (to a rating of 40 wt % expected in the compressor). The Laboratory process involved the use of Gas Chromatography machine to ascertain the values of the mole ratio, molecular weight and critical temperatures. Prode properties and Refprop softwares were used to ascertain other refrigerant properties of the mixture. The results indicated that the mixture of R600a with lubricant confirm mineral oil as being the most appropriate for the operation. The experimental results indicated that the refrigeration system with cooking gas refrigerant worked normally and was found to attain high freezing capacity and a COP value of 2.159. It is established that cooking gas is a viable alternative refrigerant to replace R600a in domestic refrigerators. Hence, its application in refrigerating systems measures up to the current trend on environmental regulations with hydrocarbon refrigerants

This paper introduces the subject of industrial cooling and discusses the most important energy savings that are possible in this area. Cooling is very expensive, so it is important that it is used only where necessary, and that only the most efficient technology is used. For thermodynamic reasons, the energy efficiency of a cooling system increases with decreasing temperature differential. It is therefore crucial to keep this differential as low as possible. Three main types of cooling systems prevail in industrial environments: dry cooling, evaporative cooling, and compression cooling. This paper explains their main working principles and characteristics. Other types, such as absorption cooling, gas expansion, and thermo-electric cooling, are not treated in this application guide because of their limited presence in industry. Each system has its own application domain. The choice of the right cooling system is one of the important initial decisions that must be taken in order to achieve maximum energy efficiency. Furthermore, this paper discusses several specific energy saving actions for each of the three cooling systems. Significant energy savings can be made by installing variable frequency drives on fans (dry cooling, evaporative cooling), pumps (evaporative cooling, compression cooling), and compressors (compression cooling).

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 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.

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.

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Elevating Tactical DDD Patterns Through Object Calisthenics

Dorra 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!

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs

Alex Pruden

This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
