Shahejie marl in the Shulu Sag is a crucial resource for unconventional hydrocarbon exploration China. Although breakthroughs have been made tight oil this area, mechanisms underlying formation of reservoir and factors controlling its ‘sweet spots’ not thoroughly studied. To understand pore structure characteristics influencing reservoir, we analyzed core samples from Wells ST1 ST3. A series ex...

In this note we deal with a practical problem arising at ENCI Netherlands BV. ENCI is a major producer of cement. Its factory site is located south of Maastricht where an important ingredient of cement, marl, is digged from a quarry. The following situation occurs at the site of ENCI. There are different kinds of traac on the site and the vehicles of each kind of traac follow a xed route on the...

The basic property of standard laboratory tests is that they are conducted on samples of simple geometry and stress state. It is a common practice to use material parameters obtained from such tests in numerical models that describe more complex stressdependent phenomena. For this reason, numerical modelling results have to be verified either through models or during construction of actual stru...

The Crow Creek Member is one of several marl units recognized within the Upper Cretaceous Pierre Shale Formation of eastern South Dakota and northeastern Nebraska, but it is the only unit that contains shock-metamorphosed minerals. The shocked minerals represent impact ejecta from the 74-Ma Manson impact structure (MIS). This study was aimed at determining the bulk chemical compositions and ana...

This paper describes a new HRTF collection, measured at the Music and Audio Research Laboratory (MARL), at NYU. This collection of 40 datasets, consists of repeated HRTF measurements on 4 subjects (10 HRTF sets per subject). Analysis of the data offers an understanding of the expected degree of variation in HRTF sets, which, when supported by subjective evaluation, can provide deeper insight fo...

Recent advances in sensing, actuation, and computation have opened the door to multi-robot systems consisting of hundreds/thousands robots, with promising applications automated manufacturing, disaster relief, harvesting, last-mile delivery, port/airport operations, or search rescue. The community has leveraged model-free multi-agent reinforcement learning (MARL) devise efficient, scalable cont...

Dear Editor, Underwater distributed antenna systems (DAS) are stationary infrastructures consisting of multiple geographically elements (DAEs) which interconnected through high-rate backbone networks [1]. Compared to centralized systems, the DAS could provide a larger coverage area and higher throughput for underwater acoustic (UWA) transmissions. In this work, exploiting low sound speed in wat...
