Design, analysis and performance evaluation of a mechanical gyratorIjrdt Journal
The project focuses on the development of an efficient and safe system for navigation for disabled people. Such a system should enable the user to control with minimum effort and should be stable in all practical situations. A gyrator is neither a motorcycle nor a four wheeler. It is a vehicle made up of an inner frame which is encompassed and supported by two large coaxially aligned wheels. The inner frame is supported by a common axle as a result, is free to oscillate back and forth relative to outer wheels. The inherent instability has limited its potential as a commercially available vehicle. But by reducing this oscillation to an optimum value by incorporating internal braking, we could make a very stable navigation system. In order to achieve motion, a shift in the centre of gravity of the inner frame is required. Two independent electric motors provide the driving torque to gearbox which drives the large outer wheels. This unique design gives the vehicle a clear advantage over conventional 4wheeled and 2wheeled vehicles as it has zero turning radius. Key word:- Inflation Pressure, Pressure switch ,Pressure guage, Solenoid control valve, DC Compressor.

EFFI-CYCLE is a national level intercollegiate design competition held annually by Society of Automotive Engineers (SAE) for undergraduate students for simulating real world engineering design projects and their related challenges. It gives a wide platform for the students to work in teams and to come up with innovative design in addition to designing and fabrication of an energy efficient hybrid human powered three wheeled electric vehicle. This year’s theme of the competition is ‘Light Weight Season’, in which teams are required to keep the weight of the vehicle below 160 kgs. Team GARUD is one such group of highly motivated individuals who are recklessly working towards the realization of this goal since its very inception. To achieve this, Team GARUD has adopted various Light Weight approaches.
The designing of the vehicle have been done on SOLIDWORKS 2014 while the design analysis has been done on ANSYS 2014. Various light weight approaches like Light weight wheels, seats and steering have also been adopted. The innovations include use of rear wheel steering instead of conventional front wheel steering and use of universal joints in front axle. This way along with lot other ways, we have succeeded to bring our vehicle weight up to 140 kgs. Team GARUD aims to design a cost effective, aerodynamically stable, comfortable and ergonomically suitable tricycle that meets the need of the market and can be produced by a fictitious firm effectively.
The objective of the project is fabrication of an off-road vehicle. It
contains various parts like roll cage, braking, suspension, engine,
steering, wheel assembly, braking, transmission etc. In fabrication
process we assemble all parts together.
The objective of our project is to fabricate an All-Terrain Vehicle. The
main purpose is to fabricate a single sitter high-performance and safe
vehicle that will take the ruggedness of rough roads with maximum
safety and driver comfort. This project provides an in-detail
description of the fabrication of an ATV vehicle. Components used in
fabrication are chosen according to their availability and reliability.
This report aims to fabricate an ALL-TERRAIN vehicle (ATV) by the
SAE BAJA 2021 rulebook
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).

Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...SOFTTECHHUB
The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

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.
