A lot of plumbings such as gas pipes and water pipes exist in factories and so on. However, it is difficult for humans to inspect them directly because they are laid underground. Therefore, automated inspection by robots is desirable, and many efforts have been done to solve this problem. However, many of existing inspection robots have to rotate the camera to record images in piping because a ...

Extended abstract Introduction Piping erosion is one of the common water erosions usually occurs in soil with low infiltration and soluble minerals that finally changes landscape. Different factors control its occurrence and development. To predict piping occurrence/hazard through modeling, effective factors should be prioritized and considered as inputs of the model. The present study...
A failure of the non-structural component can cause significant damages in critical facilities such as nuclear power plants and hospitals. Historically, it was reported that the damage from the leakage of sprinkler systems, resulted in the shutdown of hospitals for several weeks by the 1971 San Fernando and 1994 North Ridge earthquakes. In most cases, water leakages were observed at the cross j...
Background and aim: Among the most important challenges facing the patients and managers in health system is the issue of receiving additional charges known as “kickbacks”. Despite the fact that legislators have generally considered this act as illegal, there is a different judicial ruling because the nature of treatment contracts in private centers such as offices and public center...
To investigate current practices and identify challenges of piping prefabrication, this paper conducts a comprehensive survey to mechanical, electrical, and plumbing (MEP) contractors. This paper is performed in three main steps. First, the current state of piping prefabrication, the attitude of MEP contractors to piping prefabrication, and the challenges of piping prefabrication are identified...
OBJECTIVES To evaluate exposure to lead and other metals from drinking water as a result of the materials used for pipes in the supply areas of the Basque Country (Spain). METHOD Random sampling of properties in the supply areas was carried out. A total of 3,295 samples were taken in 154 areas, which together represented 87% of the properties supplied in our region. A method known as random d...
Background: Provision of safe water and sanitation is important for the health and welfare of the community. Improper conditions in the transmission and distribution of water, the most important causes of secondary pollution and water-borne disease outbreaks is. This study investigates quality of drinking water s bacteriological characteristics coming from water cooler units in Shahid Behe...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
In this paper we argue for the existence of covert pied-piping in wh-questions through a previously unnoticed pattern of intervention effects in superiorityobeying English multiple wh-questions. We show that the preference of covert pied-piping is for movement of larger constituents, unlike overt pied-piping. We argue that this discrepancy stems from conflicting requirements of PF and LF: overt...
