The present methodology for evaluating complex questions at TREC analyzes answers in terms of facts called “nuggets”. The official F-score metric represents the harmonic mean between recall and precision at the nugget level. There is an implicit assumption that some facts are more important than others, which is implemented in a binary split between “vital” and “okay” nuggets. This distinction ...

It is considered to be available in reducing the weight of automobiles that the aluminum alloy is applied to manufacture them. The spot welding of aluminum alloys is difficult because of high welding current and small electrical resistance. It is necessary to clarify the relation between the nugget formation and the welding conditions. In this study, the relation between the spot welding condit...

The purpose of this study was to determine the effect promotion on consumer satisfaction with Chicken Nugget So Good Food at Transmart Gatot Subroto Medan, product location and products Medan. population in Medan 6531 customers samples used were 44 customers, while determination technique Incidental Sampling. data sources are primary data, namely obtained directly from research secondary derive...

The in-process changes of weld nugget growth during the Resistance Spot Welding were investigated based on the resistance of input electrical impedance. To compute the time varying resistance of input electrical impedance, the welding voltage and current signals are measured simultaneously and then converted into complex-valued signals by using Hilbert transform. Comparing with the dynamic cont...

Surface interaction at the worksheet/worksheet interface during resistance spot welding of aluminium alloy 5182 with spherical tip electrodes was investigated. Oxide layer cracking and nugget formation were focused. Both experimental work and finite element analysis were employed to explain the contact behaviour at this interface. It was found that sheet separation and thus bending occurred dur...

In this paper, we describe the event nugget annotation created in support of the pilot Event Nugget Detection evaluation in 2014 and in support of the Event Nugget Detection and Coreference open evaluation in 2015, which was one of the Knowledge Base Population tracks within the NIST Text Analysis Conference. We present the data volume annotated for both training and evaluation data for the 201...

Resistance spot welding process comprises of electric, thermal and mechanical phenomenon, which makes this process complex and highly non-linear and thus, it becomes difficult to model it. In order to obtain good weld nugget during spot welding, hit and trial welds are usually done which is very costly. Therefore the numerical simulation research has been conducted to understand the whole proce...
