A general digital linearising method for transducers

A practical three-point interpolation algorithm is presented which corrects for manufacturing tolerances, zero offset, scaling errors and nonlinearity of transducers and signal conditioners. The algorithm is applicable to data-acquisition systems which make use of a microprocessor. Each measuring channel requires three parameters. One simple universal routine using these parameters calculates the value of each measurand. Results are given for eight temperature transducers

[Transcription begins] 23 Nov 44 10 AM Dear Folks, Stealing a few minutes to write you a note! We work only half a day today and the cooks have planned a big meal for us this noon – Turkey and all the fixings. Much excitement here this week. We learned Monday that thirty five WACs from Cp Stewart were being transferred to our detachment and would arrive early Tuesday Morning (4.30) You can imagine what and (sic) hustle there was to get that many beds ready. We had to open up the wing of the barracks that we had used as a storage house and take all the storgae [storage] stuff out, set up beds, make them up, clean the place as it had never been used since it was built. Tuesday, I learned that I would have to move into that wing and be wing sergeant. So Tuesday night I moved my junk over to the cadre room. Marjorie decided she didn’t want to leave the girls, so I asked Olga Drake, the girl I play tennis with so much , to move in with me and she was pleased to do so fortunately. We have a very small room with two windows, two cots, two wall lockers, two foot lockers. We plan to fix it up with curtains, pictures, rugs, lamps, etc. I think I’ll like it for a change although it may be lonesome sometimes and I shall miss the girls in the other barracks, especially Marjorie very much when I have time to do so! It means much more work and responsibility as I have to make out the duty roster for the wing and see that everything goes allright and answer all the new girls questions, etc. I shall finish straightening out my things from the moving this afternoon I imagine. Monday, in spite of all the extra work, we went to Macon at 8.00 P.M. and played the “Blue Bombers” (Warner Robbins Civilians) and took a bad beating. I played nearly all of the third quarter and part of the fourth. I get terribly winded but I enjoy it. I’ll be home four weeks from tomorrow. Love to all Kay P.S. Isn’t it nice about the garage so near. I believe I get a gallon per day this time instead of just 5. [.5?] so if the weather is good maybe we can drive some. [Transcription ends

The Deconstructed (or Distributed) Journal - an emerging model?

Reviews the development of the Deconstructed Journal academic publishing model. The model was first proposed in something like its present form in 1997 and further developed in 1999. Although not actively promoted elements of the model appear to be emerging spontaneously from the general developments in online academic publishing

Mass Transfer in a closed stirred gas/liquid contactor: Part 2: The liquid phase mass transfer coefficient kL

The liquid phase mass transfer coefficient kL for the absorption of oxygen in tap water and in ionic solutions has been calculated from the quotien\ud \ud It is concluded that the liquid phase mass transfer coefficient is roughly proportional to the stirrer speed. The gas fraction e apparently has littl

Physical methods for soil disinfestation in intensive agriculture: Old methods and new approaches

Physical soil disinfestation is worldwide mainly applied in protected cropping systems or in small-scale intensive field crops. Continuous cropping of monocultures or different host plants for the same pest or pathogen often leads to heavily infested soils which forces growers to disinfest the soil thoroughly. The oldest method is steam sterilization which is applied for more than a century. In the 1970s hot water treatment of soils was developed in Japan. Hot water is applied to the soil surface to raise soil temperatures to lethal levels. Since the 1980s inundation became a new method in the Netherlands and is applied in bulb cultures. This so-called flooding of soils creates anaerobic soil conditions in which toxic compounds like greenhouse gases are produced. A new approach in soil disinfestation in the current century is hot air treatment which is developed in Israel. The method is based on blowing extremely hot air into soil particles which are thrown above soil surface into a heat chamber by a rotary spading device. In the Netherlands renewed interest has started in radiation of soil with micro waves. Radiation of soil or other substrates has been studied for decades. The mechanism is that the heat produced by radiation is lethal to pathogens and pests. Anaerobic soil disinfestation (ASD) with incorporation of fresh organic matter in soil is a method developed in the Netherlands. A new and promising Dutch development in ASD is the application of defined products. Advantages and disadvantages of all methods are presented in this paper

REDUCTION OF ENERGY CONSUMPTION BY USING LOW-TEMPERATURE FUEL CELLS

Limited resources, CO2 debate and protection of our environment are subjects of public discussion nowadays. There is a consensus that the efficient use of energy will be one of the challenges with the highest priority in the future. From building services engineering to passenger and freight transport – there will be significant changes in all areas of daily life
