In this paper, we describe a tool that allows one to track the output of every module of a search engine. The tool provides the ability to perform pseudo error-correction by allowing the user to modify these outputs or tune parameters of the modules to check for improvement of results. Often it is important to see if certain surface level changes can help in the improvement of the result qualit...

In the era of non-volatile memories, racetrack memory is a promising technology to pack hundreds bits in magnetic nanowire. A solid-state read head grown alongside nanowire sense individual which are pushed across by shifting force. However, probabilistic nature this movement inflicts positional errors. Therefore, robust and low-cost error correcting codes essential for reliable alternative on-...

This paper proposes a method for evaluating grammatical error detection methods to maximize the learning effect obtained by grammatical error detection. To achieve this, this paper sets out the following two hypotheses — imperfect, rather than perfect, error detection maximizes learning effect; and precisionoriented error detection is better than a recall-oriented one in terms of learning effec...

In this work the performance of a wavelength division multiple access (WDMA) system with direct detection receiver is investigated. For this purpose, the probability of error in a WDMA network with OOK modulation considering crosstalk, ISI, photo detector noise and thermal noise is calculated and the effect of each on system performance is investigated. The system performance in presence of PIN...

Error detection plays an important role in fault-tolerant computer systems. Two primary parameters concerned for error detection are the latency and coverage. In this paper, a new, hybrid error-detection approach offering a very high coverage with no detection latency is proposed to protect the data paths of high-performance microprocessors. The feature of no detection latency is essential to r...

The purpose of this paper is to identify structural changes in the Korean housing market for evaluating the sustainability of the Korean housing market and to derive important implications to seek housing business strategies and public policies. Two time periods were analyzed: April 2001–December 2007 and January 2008–December 2014 to identify the impact after the global financial crisis of 200...

A fully computable upper bound for the finite element approximation error of Allen– Cahn and Cahn–Hilliard equations with logarithmic potentials is derived. Numerical experiments show that for the sharp interface limit this bound is robust past topological changes. Modifications of the abstract results to derive quasi-optimal error estimates in different norms for lowest order finite element me...

Because of the traditional methods of video error checking are unfitted to the network environment in which the packet loss rate frequently changes, this paper proposes an adaptive error checking solution on the basis of estimation of the change trend of packet-loss rate. By setting the threshold value of packet-loss rate, the solution takes advantage of improved auto repeat request supported b...
