  • XRF and the challenge of miniaturization in electronics packaging

    When Jack Kilby demonstrated the first working integrated circuit back in 1958 his main priority was miniaturization. The invention of the transistor in 1948 meant that computers no longer had to rely on large sized, thermally inefficient vacuum tube technology. The race to see just how small ICs could get had started. Since Jack’s day, semiconductor devices have become ...

  • Facilities Under Positive Pressure

    Building pressure is the difference between the outside air supplied to a building and the air removed from inside a building.  Typically, a facilities managers are trying to achieve a building with slight positive building pressure, meaning more air is supplied to the building than is removed from the building. ...

  • How Your Road Weather Stations Remain Precise into Old Age

    When the temperature is below zero and the fog settles on fields and trees like a veil, the world becomes white as in a fairy tale. But what seems so idyllic white entails risks, because the road is now covered by a fine white ice layer. No one can see with the naked eye how thick or slippery this ice layer is exactly. This can only be measured by technical assistants such as automatic ice ...

  • Determination of diurnal water level fluctuations in headwaters

    The aim of this paper is to study diurnal fluctuations of the water level in streams draining headwaters and to identify the controlling factors. The fieldwork was carried out in the Gryżynka River catchment, western Poland. The water levels of three streams draining into the headwaters via a group of springs were monitored in the years 2011–2014. Changes in the water pressure and water ...

  • Big Data: It’s all about the strategy

    Big Data, a huge amount of data, is a challenge for researchers and analysts. Although the data sets can lead to many new insights after the evaluation, their complexity, fast rate of change, and simply their amount makes it almost impossible to process them with classic methods and without smart technical aids. Images, audios, videos, GPS satellite data, internal company information, social ...

  • Area Monitoring: Diffusion Sampling

    Indoor and outdoor gas hazards that exist in open areas are usually monitored using diffusion-type sensors. A diffusion sensor has no active sample-drawing system; diffusion sensors rely on the ambient air movement and pressure to deliver the sample to the sensing element. Diffusion-type sensors are a reliable and cost-effective way to monitor open area gas hazards. When installing diffusion ...
