Microgrids, Electric Vehicles and Wireless ChargingJeffrey Funk
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how electric vehicles will become economic feasible if the right design decisions are made to benefit from the falling costs of electronics. One key decision is the use of micro-grids to enable direct charging of the batteries, which is more efficient. A second key decision is the number of recharging stations and thus the frequency by which users can recharge their vehicles. More frequent recharging means smaller batteries can be used and thus the slow rate of improvements for energy storage densities can be overcome. A third key decision is wired vs. wireless charging. Wireless charging eliminates the time consuming maintenance and fitting problems of wires and thus enables faster hookups. It also benefits from the rapidly falling cost of electronics; the falling cost of ICs, power electronics, and thin-film coils means that wireless charging is likely to become economically feasible in the near future and allow the problem of low energy storage densities of batteries to be solved.
It systems allow power to be transferred from one electrical network to another electrical network without need for wires or exposed contacts. There has been rapid expansion of WPT in mobile phone chargers and electric bulb and charging electric vehicles and dynamic charging electric vehicles, also called road powered electric vehicles. It is expected that WPT industry will grow persistently in coming decaded, commonly wireless power transfers are conducted using an inductive coupling and followed by magnetic induction , we use magnetic induction using copper wire with a diameter., The wireless power transfer field would be in high demand for electric power to be supplied in the future.

Hi there,
Many of us forgot to charge their mobile phones and if there any powercut we can't charge the mobiles right ! . These problem is solved here... For more details download this ppt Now.
Abstract: We need energy for every day today work of our life. There are many conventional methods of energy generation but these are depleting very fastly hence non-conventional energy system is very essential at this time to our nation. So an alternate method of non conventional energy generation is proposed in this project. In this project we are generating electrical power as non-conventional method by simply walking or running on foot step.Here Dynamometer is used for converting mechanical energy into electrical energy. The voltage generated by this sensor is stored in battery which will be later on transmitted wirelessly to charge the mobiles.
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.

Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
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.

17. Why we choose 125KHz for high power application?
• Same as Qi frequency band => 100KHz~148.5KHz
• Higher efficiency thanks to better magnetic material and electronic components
• According to Ishida Kazuhito-san, who was the Technical Standard Director of
Qualcomm Japan
MIC (日本總務省) will undertake a new rulemaking for magnetic coupling
technology using 100k-148.5kHz band at most 100 W later this year, targeting
completion at the end of 2020. Currently we have no regulation specified for WPT
in this band.
• jjPlus uses the resonant technique developed in EV wireless charging in the
125KHz wireless power module design, so we can achieve better XYZ freedom
than Qi method with higher efficiency
