A group of scientists led by Kongu Engineering College in India investigated the use of waste neem oil as a cooling solution for PV modules. Neem oil is extracted from the seeds of the neem tree and is commonly used as a medicine for some skin diseases.

The researchers explained that this oil acts like phase-changing materials (PCMs), which can absorb, store, and release large amounts of latent heat over defined temperature ranges. PCMs have often been used at the research level for PV module cooling and the storage of heat.

“The neem oil has a good thermal range, is physically high in density, is chemically stable and noncorrosive, is environmentally pollution-free, reusable, and recyclable, and is economically low-cost and easy to dispose of,” they added. “Commonly, any PCM used for cooling purposes should have low thermal conductivity, stability, and cycling. The neem oil has fulfilled all the limitations.”

these past few days have cumulatively been the worst in a long while.

replaced my battery today and my power steering assist failure light is still on so now I'm inclined to believe it is my power steering module after all and that means :) i can't actually fix it myself :)

that requires a computer to program it properly and a lot of know how that I do not have! it could also be the pinion bearing near the power steering module because if that goes bad, sometimes that can cause the PCM to not read correctly (i.e. power steering assist failure)

it could also be the strut and engine mount, because people with the same type of car as me have said that they replaced those and their power steering came back.

at this point i dont know what im going to do because i can't afford to take my car to a shop and get it serviced. i dont even have the money to take it and get the problem troubleshot either.

i dont even know if all mechanics are equipped to deal with electronic power steering systems or if most of them only work with hydraulic ones.

big number.....

40: Who wish I could be (sic): this is kinda hard. I can't really think of a particular person I wish I could be over myself, at least not in totality. more generally I very often wish I was more functional and productive and driven and such. just like, better at carrying things out and following through. I'm always envious of the type of cool well organised girl who seems to have all her shit together.

44: A random fact about anything: The Roland TB-303 Bass Line synthesizer was marketed as a replacement for bass guitar, but because of its unrealistic sound and difficulty to use it was a commercial failure at the time of release. Because of this, remaining stock were sold off very cheaply and many units were resold and donated by disappointed customers and years later the 303 became very popular among house music producers, integral to the development of Acid House. The squelchy 303 tone and musicality of the tone controls remains iconic and well-recognised to this day.

44: A random fact about anything: CD Audio is encoded with pulse code modulation (PCM) with a sample rate of 44,100 Hz and a bit-depth of 16. this means that in the recording or conversion of audio to this format, the amplitude of the analog signal is sampled 44,100 times each second at a resolution of 16 bits (as a two's complement integer, -32768 to +32767 in decimal). The bit-depth determines the dynamic range possible for a recording, and the sample rate determines the top of the frequency range (the sample rate is twice the value of frequencies that can be represented, due to the Nyquist-Shannon sampling theorum). The sample rate is chosen such that it can in theory represent the full range of frequencies humans are capable of hearing (up to 22.05 kHz)

44: A random fact about anything: even though it's considered outdated and is no longer present as a diagnosis in the DSM-5, on paper I was diagnosed with Asperger's Syndrome in ~2018 because the psychiatrist I saw still used the DSM-IV for diagnosis, for some reason. (I don't personally identify with this label because of its eugenicist history and connotations)

How do vehicle diagnostic systems work?

In today's digitally-driven automotive landscape, vehicle diagnostic systems play a crucial role in ensuring the smooth operation and longevity of vehicles. These sophisticated systems monitor, analyze, and report on various aspects of a vehicle's performance, allowing for timely identification and resolution of issues. Let's delve into how vehicle diagnostic systems work and their significance in maintaining vehicle health.

Understanding Vehicle Diagnostic Systems

Vehicle diagnostic systems, often referred to as On-Board Diagnostics (OBD) systems, are integrated electronic systems that continuously monitor and analyze the performance of a vehicle's engine, emissions control systems, and other critical components. They rely on a network of sensors, actuators, and onboard computers to gather data and provide real-time feedback on the vehicle's operational status.

Key Components of Vehicle Diagnostic Systems

Sensors: Vehicle diagnostic systems are equipped with a variety of sensors that monitor key parameters such as engine speed, temperature, air-fuel ratio, exhaust emissions, and vehicle speed. These sensors provide real-time data to the onboard computer for analysis.

Onboard Computer: The onboard computer, also known as the Engine Control Module (ECM) or Powertrain Control Module (PCM), serves as the brain of the vehicle diagnostic system. It receives data from the sensors, processes it using predefined algorithms, and generates diagnostic trouble codes (DTCs) when abnormalities are detected.

Diagnostic Trouble Codes (DTCs): When a fault or anomaly is detected within the vehicle's systems, the onboard computer generates a DTC, which is a standardized code that indicates the nature and location of the problem. These codes are stored in the vehicle's memory and can be retrieved using a diagnostic tool for troubleshooting.

Diagnostic Tools: Diagnostic tools, such as OBD scanners or scan tools, are used to retrieve and interpret DTCs from the vehicle's onboard computer. These tools communicate with the vehicle's diagnostic system via a standardized communication protocol, such as OBD-II, to access diagnostic information and perform diagnostic tests.

How Vehicle Diagnostic Systems Work

Data Acquisition: Vehicle diagnostic systems continuously collect data from sensors located throughout the vehicle, including the engine, transmission, exhaust system, and emissions control systems. This data includes parameters such as engine RPM, coolant temperature, oxygen sensor readings, and vehicle speed.

Data Analysis: The onboard computer analyzes the incoming data in real-time, comparing it to predefined thresholds and performance criteria. If any parameters fall outside of acceptable ranges or if a malfunction is detected, the onboard computer generates a DTC corresponding to the specific issue.

DTC Storage and Retrieval: The generated DTCs are stored in the vehicle's memory for future reference. When a driver or technician encounters a problem with the vehicle, they can use a diagnostic tool to retrieve the stored DTCs and diagnose the underlying issue.

Diagnostic Alerts: In some cases, vehicle diagnostic systems may alert the driver to potential issues through warning lights or messages on the instrument panel. These alerts indicate the severity of the problem and prompt the driver to take appropriate action, such as seeking service or maintenance.

Significance of Vehicle Diagnostic Systems

Vehicle diagnostic systems play a crucial role in vehicle maintenance and repair by:

Early Detection of Issues: By continuously monitoring vehicle systems, diagnostic systems can detect potential issues before they escalate into more serious problems, allowing for timely intervention and preventive maintenance.

Improved Troubleshooting: DTCs generated by diagnostic systems provide valuable diagnostic information to technicians, enabling them to pinpoint the root cause of a problem quickly and accurately, reducing diagnosis time and repair costs.

Enhanced Performance: By ensuring that vehicle systems are functioning optimally, diagnostic systems contribute to improved fuel efficiency, reduced emissions, and overall vehicle performance.

Compliance with Emissions Regulations: Vehicle diagnostic systems help ensure compliance with emissions regulations by monitoring emissions control systems and alerting drivers to potential issues that could affect emissions performance.

Conclusion: Keeping Vehicles Running Smoothly

In conclusion, vehicle diagnostic systems play a vital role in maintaining the health and performance of modern vehicles. By continuously monitoring key parameters, analyzing data, and generating diagnostic trouble codes, these systems enable early detection of issues, facilitate efficient troubleshooting, and contribute to improved vehicle performance and emissions compliance. As automotive technology continues to evolve, vehicle diagnostic systems will remain essential tools for ensuring that vehicles operate reliably and efficiently for years to come.
