The weekly report summarizes the progress of the Engineering Team. They tested a circuit using a Toshiba resistor and measured the temperature at different resistor values. The team changed to a variable resistor which did not affect the temperature. A water heater circuit was connected to a microcontroller to measure water flow every 10 seconds. The strong point was knowledge of water heater circuits using variable resistors to control voltage. The weak point was needing to study boiler datasheets to understand controlling temperature with voltage. The next week's job is to design a new control.

This weekly report summarizes the progress of a student group working on designing a water heater. The group determined they would add a function to save energy by researching water pressure. There are two pressure switches that could be used - a pressure switch that activates at a set pressure value and a flow switch that activates based on water flow rate. The group analyzed that a flow switch may be better suited for their water heater design since it can still function at low pressure from a faucet. Next week, the group will research a "memory function" to track daily water usage.

Electronic components ppt
Electronic components can be categorized as either active or passive. Passive components, such as resistors, capacitors, and inductors, cannot produce power gain or amplification and require no external power source. Active components, such as vacuum tubes, transistors, and thyristors, can produce electric energy, contribute power gain to a circuit, and require an external power source. Early electronic components included vacuum tubes, which dominated electronics until being largely replaced by solid state devices starting in the 1950s. Common electronic components include resistors, capacitors, inductors, diodes, transistors, and integrated circuits.
Energy Meter
This document discusses different types of energy meters. It introduces energy meters as devices that measure the amount of electrical energy consumed by homes, industries, and commercial buildings. It describes electromechanical induction meters, which use a metal disc that revolves in a magnetic field, with a counting mechanism to record rotations corresponding to units of energy used. Electronic energy meters display energy usage digitally and can measure usage in peak vs. off-peak hours. Smart energy meters provide real-time usage data and accurate billing by communicating readings remotely. Tampering is a major concern as meters can be manipulated to under-register energy usage, resulting in lost revenue.

Engineering student KritsakornWeekana submitted a weekly report for their multi-disciplinary workshop group "Id(instinct design)". The report discussed testing a CO2 sensor where heating the sensor's surface to a high enough temperature causes it to output a voltage signal according to Nernst's equation. The testing circuit used an op-amp with an impedance between 100-1000GΩ and the sensor output a voltage of 135mV-70mV. The strong point of the circuit was using an op-amp, while the weakness was the amplifier impedance being outside the desired range. Next steps are to set up the circuit and devices for the product structure.

This document proposes a multicell switched-inductor/switched-capacitor combined active network converter (MSL/SC-ANC) for high step-up voltage conversion with high efficiency. The MSL/SC-ANC structure combines the advantages of switched inductor cells, switched capacitor cells, and active networks to provide high voltage gain with low voltage and current stress on devices. It can achieve flexible voltage conversion by adjusting the number of switched inductor and capacitor cells. The proposed converter has applications in photovoltaics, fuel cells, and other areas requiring high voltage step-up conversion.

Design to me is the consideration and respect shown to others through gestures and use of space. It is an attitude inherited from childhood where younger ones make room for elders during family gatherings. Design provides opportunities to serve people by initiating new ways to perceive needs and make life easier, as pioneers like Newton and Da Vinci did. It can also introduce new tastes for good living, as through innovators like Raymond Loewy and Steve Jobs. Ultimately, design has a strong association with human users, so it requires a human-centered approach.

- The student's engineering group is working on designing a water heater that displays the amount of water and temperature during use, and controls the temperature close to the desired value.
- Last week they presented the block diagram and some circuits, but it had problems, so they need to do more research.
- A problem is controlling the temperature if the water flow into the boiler is inconsistent, as too little or too much water flow affects how quickly the water is heated.
- The temperature control circuit works like a dimmer circuit that changes the load to control the phase shift at the triac gate using an RC circuit and diac for surge protection.
- Next week they will finalize the functions, button functions and

1. The student tested a power supply circuit using a transformer instead of an LNK306 IC due to insufficient current. A drive motor circuit was also tested using a TIP41 transistor instead of a 2N3904 due to the higher current needs of the motor.
2. Both circuits were tested successfully and can be combined. The power supply provides a constant 12V output.
3. For next week, the student will make a PCB and do further calculations to improve the design by addressing weaknesses like the transformer taking up space and the regulator getting hot under load.

This weekly report summarizes the progress of a student group working on an electric kettle design. In the previous week, the group presented the internal kettle circuit but it was not perfected. The student then researched how a thermostat works, learning it uses two switches - one to turn the power on and another normally closed switch that opens to interrupt power when the water reaches boiling temperature. For next week, the group plans to design a kettle circuit to develop their project further.

Epistemic Interaction - tuning interfaces to provide information for AI support
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.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
