worldwide networks of seismic recording instruments mostly record only translational ground motion in two or three orthogonal directions. rotational component of earthquake is not commonly recorded. several theories are available to estimate a torsional component from recorded translational components of ground motion. in this paper detailed investigations are made to study the relative perform...

The author suggests that contemporary enthusiasm for cognitive-behavioural therapy reflects our longing for swift, rational help for psychological suffering. Competition for funding threatens the psychoanalytic presence in the public sector. The psychoanalytic and cognitive-behavioural models are contrasted, and the relative richness of the psychoanalytic paradigm outlined. The author suggests ...

The cytoplasmic ground substance of cultured cells prepared for high voltage transmission electron microscopy (glutaraldehyde/osmium fixed, alcohol or acetone dehydrated, critical-point dried) consists of slender (3-6 nm Diam) strands--the microtrabeculae (55)--that form an irregular three-dimensional lattice (the microtrabecular lattice). The microtrabeculae interconnect the membranous and non...

Ground truthing tools mainly fall into two categories: automatic and semi-automatic. In this paper, we first discuss the pros and cons of the two approaches. We then report our own work on designing and implementing systems for generating chart image dataset and multilevel ground truth data. Both semi-automatic and automatic approaches were adopted, resulting in two independent systems. The dat...

few years ago, a number of news stories appeared here and there announcing "fundamental breakthroughs" in the development of machine translation from Russian into English and declaring that workable machine translation systems, if not already a reality, were just around the corner. Since then, one or two government agencies have begun to operate automatic translation facilities with which some ...

The constructs of "common ground" and "grounding" are frequently invoked in the CSCW literature as a mechanism by which participants engaged in joint activity coordinate their respective understandings of matters at hand. These constructs arise from a model of conversation developed by Herbert Clark and sometimes referred to as "contribution theory." We describe here the basic features of this ...

In this paper we present a way to use precision and recall measures in total absence of ground truth. We develop a probabilistic interpretation of both measures and show that, provided a sufficient number of data sources are available, it offers a viable performance measure to compare methods if no ground truth is available. This paper also shows the limitations of the approach, in case a syste...

ASCE 7-16 has provided a comprehensive platform for the performance-based design of tall buildings. The core of the procedure is based on nonlinear response history analysis of the structure subjected to recorded or simulated ground motions. This study investigates consistency in the ASCE 7-16 requirements regarding the use of different types of ground motions. For this purpose performance of a...
