![]() ![]() Even with such little water to survive, wildflowers bloom. "As Heather Trost put together her new album Desert Flowers, she imagined herself sitting out on the mesa amidst the arid climate and sand. Wüste moved to New York, Micheline stayed in Zurich, both still active in the music scene to this day." - Thomas Haemmerli Of course something so deep in the Zeitgeist wasn't meant to last. There was something futuristic about the sound, the vestiary style and the electronics, while the attitude remained rebellious. Consequently, only two cassettes and an EP were released. A pioneering act that fit well into the DIY spirit of punk, with its self-distributed tapes and fuck-you attitude towards the cretins of the music industry. They had an interface built for the legendary Roland MC-4B, who sequenced the modular Roland System 100M but where one output controlled a light show synchronized with the sound. With the top-of-the-line Linn drum machine clocking the beat, Wüste's guitar and Micheline on the Yamaha synthesizer created a unique sound of danceable electronic music. Frustrated by organizational friction and constant hassles with band lineups, Wüste and Misch decided to do everything as a twosome: self-mixed, self-styled, self-produced. In 1980 the Aboriginal Voices were formed, initially with vocalist Magda Vogel (of later UnknownmiX fame), who was trained as a classical singer. She was already playing with Wüste in the band Doobie Doos, a band where everyone played an instrument they didn't master. ![]() Voilà: a musician who was as stylish as she was tough. Micheline had a classical piano education, had left home early, worked as a lighting technician in a strip joint and at Booster, the hottest boutique in town. A couple, good-looking, styled, looking cool into the cold neon light, with a danceable beat and sequenced electro sounds, to which Micheline gave a very unique touch when she sang in French and English. In Zürich's underground, the duo Aboriginal Voices caused a stir at that time. A fertile ground for the militant youth movement that exploded in 1980 and stirred up the city of banks, Protestantism, and boredom with raw wit and expressive violence. The scene included the female band Kleenex, whose minimalism was praised by the London music press, while the world's most important rock theorist, Greil Marcus, wrote an ode highlighting Zürich's role as the birthplace of Dadaism. One such example, Henrich 'Wüste' Zwahlen, who had learned the violin, attended a jazz school and went into prog-rock before joining the Nasal Boys, one of the first punk bands in Zürich. Contrary to legend, even back then, it was often those with a musical background who were the most successful. "For a quarter of an hour, Zürich was the navel of the world. ![]()

That number more than doubled in 2020.ĭittmar said part of that divide is due to more targeted recruitment and support for these candidates coming from the Democratic side. In 2018, 15 women of color from the Republican party were nominated in House primaries. But even though Democrats have higher numbers than Republicans, Republicans have seen notable gains compared to before the 2020 cycle. There’s a stark party divide when it comes to the number of women and women of color nominated in the primaries. (CAWP no longer reports an aggregate “women of color” in their analyses, and instead breaks it down by race and ethnicity. In this data set, “women of color” includes women who identify as one or more of these categories, including women who identify as white with one of these other racial/ethnic identities: Black, Asian American/Pacific Islander, Latina/Hispanic, Native American/Alaska Native/Native Hawaiian and Middle Eastern/North African. “As you see women of color succeed at this level, hopefully, it both inspires other women of color to run, but also proves to practitioners and donors and gatekeepers in the political system that these women are well poised to succeed,” Dittmar said. That includes 92 Republicans and 171 Democrats - a record for both parties. “At least some of those persist and might be contributing to the slower or lack of significant progress in this cycle.”Ī record-high number of women of color - 263 - ran for the House this year. “It just serves as a reminder that despite having two cycles in which we were talking consistently about record-breaking years for women, that we can't just set aside the structural barriers and concerns that we have pointed out before and during those cycles in 2022,” Dittmar said. This year, 582 ran and 259 were nominated. The record for women House nominees was set last cycle, when 583 ran and 298 were nominated. A record number of women are nominees for governor and state legislatures, but the same can’t be said for the House and Senate. With most primaries completed for the 2022 cycle (sorry Louisiana), CAWP has compiled the number of women nominated to the general election. Plus, women only made up around 30 percent of House nominees this year - meaning it’s far from gender parity. While that’s an indicator of progress, says Kelly Dittmar, director of research and scholar at the Center for American Women and Politics at Rutgers University, it’s far from representative of the increasing racial and ethnic diversity of the nation. Of the 259 women nominated in House primaries this year, 43 percent are women of color - the highest percentage for the demographic in recent cycles. ![]() ![]() ![]() That story may one day become known, but for now, Minassian’s story comes fragmented from a cluster of people who knew him, but none who appear to have known him well. ![]() Photo by Craig Robertson/Postmedia Network I’d love to know what exactly made him think he was an incel.” A police officer walks past a van used in a deadly attack on pedestrians in Toronto on April 23, 2018. “It will be interesting to read about Alek’s story as more details about his life unfold. “Well, he certainly got us noticed,” one member wrote. “They should be scared, this is what happens when you deny so many men love and affection for their entire lives,” said another.

TI has a design tool that can provide you with a LUT or fourth-order polynomial and regression function, with examples of how to apply these math functions in C code for your controller to get the most accurate temperatures from a thermistor.Ī LUT typically ranges from -40☌ to 125☌, but will vary based on the thermal limits of the thermistor. These are simple math functions that can process faster than an LUT with interpolation. Most PTCs are based on polynomials.ĭon’t be concerned once you get the hang of polynomials, you will get better accuracy plus, you will not need a LUT in your controller. You must apply the polynomial fit yourself and then solve the regression function (the temperature based on the curve fit) to obtain the temperature. Another way to describe polynomials is that they provide a curve-fit equation for a slope. A polynomial is a mathematical expression of variables that involves only the operations of addition, subtraction, multiplication and non-negative integers. Polynomial equations are the most accurate way to get a temperature from a thermistor. PTCs can use a polynomial equation, given the linear output of the device. The Steinhart-Hart equation is more accurate than a LUT. It will require natural log math to complete, and you must have a floating-point controller or floating-point math libraries to perform the calculations. I will discuss this further in the Linear Interpolation section.Īnother method is to use a Steinhart-Hart equation, which is based on a 3rd order polynomial curve fit. A 5☌ LUT will require 33 elements, but no one wants to see 5☌ resolution, so further processing of the LUT will be necessary in order to get better than 5☌ or 1☌ of resolution. To reduce the number of elements, you could use a 5☌ LUT, but then you may have some linear error in the calculation. A 1☌ LUT table has 166 elements and must be stored in your controller, but this uses up controller memory. The most common method uses a look-up table (LUT), also known as a resistance table, normally provided by the thermistor manufacturer. Once you have converted the voltage to an ADC representation, there are a number of ways to get the actual temperature from the thermistor’s V Sense voltage. Where I bias is 200 ♚ (default standard current for a TMP61 family part) and V Sense is 1.63 V. Where the ADC resolution (12-bit ADC (2 12)) is 4,096 total bits, V REF is 3.3 V and the measured ADC LSB value is 2,024 (example ADC LSB value from a Texas Instruments (TI) TMP61 thermistor family test board).Įquation 2 calculates the resistance from the voltage divider’s V Sense:Įquation 3 calculates the resistance from the constant current, I bias: You can use Equation 1 to convert the measured 12-bit ADC LSB value to a voltage: Figure 1 shows both the voltage-divider and constant-current circuits.įigure 1. Voltage-divider and constant-current circuit implementations A common ADC resolution is 12 bits for many low-cost MCUs, so the formulas in this article will use 12-bit resolution. This article explains how to use an NTC or a PTC thermistor with an ADC, along with the various process techniques to convert ADC measured results into a usable temperature value.Ī typical thermistor circuit provides a voltage (V Sense) that is applied to an ADC input the ADC then converts this voltage to an LSB (least significant bit) digital value that is proportional to the input voltage. The most basic circuit is based on a resistor divider attached to a low-cost microcontroller (MCU) with an analog-to-digital converter (ADC). ![]() ![]() The simplest and most cost-effective circuits use a negative temperature coefficient (NTC) or positive temperature coefficient (PTC) thermistor to measure temperature.
