Using temperature and pressure records from Czech meteorological stations and NCEP=NCAR reanalysis series, we tested for the presence of detectable nonlinearity in univariate and multivariate climatic time series. The method of surrogate data was utilized for nonlinearity detection – results of nonlinear prediction for the original series were compared to the results for series whose nonlinear ...
A graphical method has been developed for determining the coefficient of consolidation from the transient phases of a flow-pump permeability test. The flow pump can be used to infuse fluid into or withdraw fluid from a laboratory sediment specimen at a constant volumetric rate in order to obtain data that can be used to calculate permeability using Darcy´s law. When the initial transient-response ...
Description Eighteen (18) compressors, powered by 7600 hp Wartsila engines.

The product has passed the metrological certification and has been widely used in petroleum, chemical industry, electric power and other fields. The digital pressure gauge has high precision and stability, with error less than 1%, internal ...
Rapid changes in atmospheric pressure influence the risk of gas entry into properties. As atmospheric pressure decreases the likelihood of gas entry into the properties on the site increases. This relationship was evident from early monitoring in a vacated Gorgebridge property (see figure 1). The highest concentration of CO2 represented by the blue line, were recorded when the atmospheric ...
Here’s a throwback from six years ago today, when MadgeTech engineers and staff installed several data loggers in a car destined for destruction. MadgeTech was proud to sponsor a Demolition Derby car for the 2013 Hopkinton State Fair, driven by then 20-year-old, Roddy Tanner, of Warner. Installed in Roddy’s blue Ford LTD were an UltraShock-50G, two TSR101-50G shock loggers for ...
The title, "Transforming Australian manufacturing", presumes there is a need to review the performance of the manufacturing industries and the Government's sectorial policies for achieving best practice to leverage manufacturing capabilities of Australian firms. Pressures to reconfigure the manufacturing industry within Australia have been intense and diverse over the last decade in the ...

Recently, I learned that certain smartphones contain an actual pressure transducer. I shared this info with a friend who insisted that the phone was not really measuring pressure, but was instead using the internet to download the pressure based on the phone’s location. Now, I had to prove them wrong. So, I did what I thought was the obvious proof… I placed my phone in a small test ...
Pumps and systems are installed, started, operated, and many times, forgotten. When a problem arises, it’s recommended to install a discharge pressure gauge and suction vacuum gauge on the system. These gauges should be installed near the suction inlet and discharge outlet of the pump. These gauges are usually installed properly, recorded, and along with a pump speed measurement can be ...
This study compared the centrifuge and pressure plate methods with appropriate run durations. Samples collected in tropical soils located in Brazil along a 10-km local hydrosequence across the Cerrado–Amazonia transition (Set 1) and along a 350-km regional toposequence across the Cerrado region (Set 2) were selected to compare and discuss statistically the similarity of the soil water retention ...

Falkirk County Council, Scotland Supply and installation and maintenance of a Trash Screen blockage and Flood Warning system, 2006 - ongoing Hydro-Logic was appointed by Falkirk County Council to supply, install and commission a series of 7 sites where there were concerns over flooding. The systems were deployed to supply alarms to a central control office at Falkirk Council. The system ...
This paper describes the design, calibration, and field performance of a number of new instruments that have been used for research into the behavior of displacement piles in clays and sand. The instruments include axial load cells, surface stress transducers, and pore pressure probes. The special features of the surface stress transducers and pore pressure probes are described in detail, and ...
Problem Facade insulation testing is usually performed by using a loudspeaker in the sending room, and record the sound pressure level (SPL) with microphones in both the sending and receiving room. The difference in SPL adjusted for the size of the dividing wall element will then give an estimate of the sound reduction quality of that element. However these measurements will not say anything on ...
Dividing a water distribution network (WDN) into district metered areas (DMAs) is the first vital step towards pressure management and real losses reduction. However, other factors of water quality such as the water age must be taken into account while forming DMAs. The current study uses genetic algorithm (GA) optimization methods to achieve the desired WDN segmentation conditions in terms ...
