piping sometimes is occurred due to seepage of water in hydraulic structures. the continuty of this phenomenon decreases the safety or caused the failure of a structure. in this work, experimental tests were carried out on statically compacted natural and randomly reinforced silt sandy soil samples. the randomly reinforced samples were prepared with different lengths and percentages of an artif...

This paper proposes a description of German word order including phenomena considered as complex, such as scrambling, (partial) VP fronting and verbal pied piping. Our description relates a syntactic dependency structure directly to a topological hierarchy without resorting to movement or similar mechanisms.

One of the key design parameters to a process plant with large capacity is the risk of AIV (Acoustically Induced Vibration) on the flare piping system. AIV is a piping vibration phenomenon exhibiting high frequencies caused by large acoustic power generated by the pressure drop across a PRV (Pressure Relief Valve). The evaluation method for susceptibility of piping to AIV fatigue failure was fi...

One of the problems of existing irrigation networks is seepage phenomena. Seepage problem and its control in irrigation channels is one of the most important issues in the design, construction, maintenance and operation of these channels. In this study, simulated the rate of seepage and phreatic lines in the Mianab irrigation and drainage channels located in the Karun basin using mathematical t...

We present a proposal for the structure of noun phrases in Synchronous TreeAdjoining Grammar (STAG) syntax and semantics that permits an elegant and uniform analysis of a variety of phenomena, including quantifier scope and extraction phenomena such as wh-questions with both moved and in-place wh-words, pied-piping, stranding of prepositions, and topicalization. The tight coupling between synta...

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...

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...

The problem of finite amplitude wave propagation in fluid-filled distensible tubes, although of potentially wide general interest in industrial piping systems, finds particularly important application in biomedical circulatory phenomena. Mathematical and laboratory studies of such coupled fluid-shell interactions have led to novel contributions in the field of Biomechanics, an area of continuin...

Abstract—Cavities are frequently found beneath conduits on pile foundations in old embankments. Cavity reduces seepage length significantly and consequently causes piping failure of embankments. Case studies of embankment failures indicate that the relative settlement between ground and pile supported-concrete conduit was the main reason of the cavity. In this paper, an attempt to simulate the ...
