Cyprus is facing a growing water shortage problem, therefore water losses associated with inefficiencies of the underground water distribution system are not only causing revenue losses for the local water boards but also significantly negatively affect the national water reserves. This paper presents an outline of two research projects, related to each other, “WATERSENSE” and “URBAN WATER DIST...

As one of major underground pipelines, sewerage is an important infrastructure in any modern city. The most common problem occurring in sewerage is leaking, whose position and failure level is typically identified through closed circuit television (CCTV) inspection in order to facilitate rehabilitation process. This paper proposes a novel method of computer vision, morphological segmentation ba...

This paper contributes to the recent literature on the Green Paradox (Hoel, 2011 and Harstad, 2012) that distinguishes between regulated and unregulated regions in a Hotelling framework. In our model, different grades of oil are characterized by different costs, emission factors, and underground reserves; furthermore, the clean backstop experiences cost-reducing technical change. As a result, e...

As the utilization range of smart devices for infrastructure has widen its application owing to flourishing of smart devices, studies on the technologies to graft IT onto underground utilities are actively carried out. In particular, as underground utilities have a characteristic of invisibility, studies on a management system converged with augmented reality are demanded for the efficient mana...

Marine mammals being among the top predators in the food web tend to accumulate organic and inorganic contaminants from the environment. The body burden of contaminants in these species could reflect their foods and thus contaminant levels could serve as proxies on the changes of ecosystem. A pilot study was carried out to investigate the possibility of radionuclide leakage at Amchitka using a ...

Approximately 11% and 25% of annual Canadian oil spill accidents are gasoline and diesel spills, respectively. Gasoline and diesel spills are a challenge to conventional environmental forensic techniques because refinery processes remove most of the higher molecular weight biomarkers. This study presents a tiered environmental forensics strategy that includes such information as site operationa...

Abstract China Jinping Underground Laboratory (CJPL) is ideal for studying solar, geo-, and supernova neutrinos. A precise measurement of the cosmic-ray background essential in proceeding with R&D research these MeV-scale neutrino experiments. Using a 1-ton prototype detector Neutrino Experiment (JNE), we detected 264 high-energy muon events from 645.2-day dataset first phase CJPL (CJPL-I),...

INTRODUCTION The use of Top Coal Caving for exploiting the thick coal seam with shallow buried depth most likely has a strong negative impact on the stability. CASE DESCRIPTION Anjialing No. 1 Underground Mine is located in Shuozhou City, Shanxi Province of China. The 4# Coal Seam of this coal mine is the thick coal seam with shallow buried depth, which has the thickness of 12 m and the depth...
