  • Case Study: NCore Site X

    Jim manages this NCore site just outside of a large urban metropolitan city, and recently upgraded the site to use the Agilaire Model 8832 data logger and a Sixnet wireless modem, provided by Agilaire. The Model 8832 is networked into five Thermo i-Series analyzers, and remotely polled by an AirVision server in the main office. The site will soon get delivery of a BAM-1020 with fine/coarse ...

  • Working remotely and the LIMS solution

    Now that cell phone and internet coverage are virtually everywhere, it is extremely difficult to disconnect from work. Believe me, I know; I’ve been hiking up the side of a mountain in NC and still received phone calls and emails. Answering work related phone calls while out of breath and telling your five year old to be quiet at the same time can be quite a challenge. However, that kind of ...

  • Local groundwater supply systems for remote settlements, current state and prospects for utilization: case studies from Serbia

    Water supply for remote rural settlements is a big issue in the Republic of Serbia. Most local supply systems are developed and maintained by the local community and are in a poor condition. Based on a national strategy, this issue should be resolved with the construction of regional systems using artificial reservoirs. In this paper, case studies from three areas in Serbia are shown in order ...

  • Optimizing external carbon source addition in domestics wastewater treatment based on online sensoring data and a numerical model

    The removal of total nitrogen in wastewater treatment plants (WWTPs) is often unsatisfactory for a variety of reasons. One possible measure to improve nitrogen removal is the addition of external carbon. However, the amount of carbon addition is directly related to WWTP operation costs, highlighting the importance of accurately determining the amount of external carbon required. The objective ...

  • Case study - Remote location requires minimum concept

    A leading power supply provider in Austria took on the project of monitoring water levels at a power plant in Montenegro, in two remote locations where no infrastructure is available for installation. On top of that, site visits could only occur every two months, so a device with remote data transmission capabilities was key. Because of these factors, the customer needed an easy solution for ...

  • Solar Orbiter - Case Study

    Solar Orbiter is part of ESA’s “cosmic vision” science programme exploring planets and life, the solar system, fundamental laws and the universe. Planned for launch in 2018, it continues ESA’s long heritage in space science, solar exploration, and interplanetary missions. The Mission Via an intricate series of gravitational flybys of Venus and Earth, Solar ...

  • Optical encoders and LiDAR scanning

    Overview Modern technology is taken for granted; a driver only needs to type a destination into a SATNAV system and step-by-step instructions, journey distance and duration, driving conditions and hazards, as well as alternative routes, instantly appear. In order to work, highly accurate and up-to-date maps are required of an entire country's road ...

  • 10 Flags in Valve Chambers that Should Make You Question What Else is Wrong

    I have reached the conclusion, as a lot of you may relate too, that I may be considered one of those “cranky old men”. It shows itself in the little things. Sentences starting with the phrase “when I was your age” or ...

  • Using Lidar for WRA Campaigns: Your Questions Answered (Part I)

    In the course of conversations with wind developers new to Lidar technology, a number of questions seem to come up regularly. In this and future blog posts, I will attempt to answer these questions in some detail to benefit others who might be pondering them as well. Two very practical questions have to do with how WINDCUBE® ...

  • A decision classifier to classify rivers for river management based on their structure in China: an example from the Yongding river

    River classification is a very useful tool for river management yet still a difficult task. This paper proposed a new decision classifier (DCF) to classify rivers for Chinese river management based on existing classification systems. Aimed at river function management, the DCF with the five-layers frame was developed on reach level in a spatially nested pattern that from top to bottom are ...

  • How to Keep Your SymphoniePRO Data Secure

    Data matters. The accuracy, consistency, and yes, safety of measurement data keep many wind developers and analysts up at night. Customers often ask about the digital and physical security of RNRG instruments, so I sat down with Michael Fisher, product manager for our wind resource assessment (WRA) line, to get answers to the most common questions. Q: Why is data security important? ...

  • Map Algal Blooms with Satellite Remote Sensing Technology

    The quality of water bodies is a key determinant in the usability of the resource for the purpose required. It is therefore of great importance to managers of hydrologic resources to be able to confidently tell the status of their water resource. One of the major problems in the quality of surface water bodies is the blooming of algae and blue green algae. Algal blooms can result in ecological, ...

  • Calibration of a capacitance soil sensor is required to achieve the level of accuracy required for satellite ground truthing

    Why not make it easy with a non-capacitance based soil sensor like the HydraProbe? This study published in American Meteorological Society's BAMS journal demonstrates the extent of variability in readings one can expect with a soil moisture sensor based on capacitance technology.  To ...

  • Reducing costs through precise remote tracking

    Historically, inline inspection (ILI) tools used to identify defects on oil and gas pipelines have been tracked by field teams. However, recent technology advancements now allow pipeline owners to track pigs remotely, which is a much safer and cheaper alternative to traditional tracking. As pipeline integrity technology advances, asset owners are now using a wide variety of tools to detect ...

  • Application of spatial Markov chains to the analysis of the temporal–spatial evolution of soil erosion

    Soil and water conservation in the Three Gorges Reservoir Area of China is important, and soil erosion is a significant issue. In the present study, spatial Markov chains were applied to explore the impacts of the regional context on soil erosion in the Xiangxi River watershed, and Thematic Mapper remote sensing data from 1999 and 2007 were employed. The results indicated that the observed ...

  • A study of the relationship between wetland vegetation communities and water regimes using a combined remote sensing and hydraulic modeling approach

    Hydrologic condition is a major driving force for wetland ecosystems. The influence of water regimes on vegetation distribution is of growing interest as wetlands are increasingly disturbed by climate change and intensive human activities. However, at large spatial scales, the linkage between water regimes and vegetation distribution remains poorly understood. In this study, vegetation ...
