Chinese Pinyin input method is very important for Chinese language information processing. Users may make errors when they are typing in Chinese words. In this paper, we are concerned with the reasons that cause the errors. Inspired by the observation that pressing backspace is one of the most common user behaviors to modify the errors, we collect 54, 309, 334 error-correction pairs from a realworld data set that contains 2, 277, 786 users via backspace operations. In addition, we present a comparative analysis of the data to achieve a better understanding of users’ input behaviors. ...

A virtual instruction set architecture (V-ISA) implemented via a processor-specific software translation layer can provide great flexibility to processor designers. Recent examples such as Crusoe and DAISY, however, have used existing hardware instruction sets as virtual ISAs, which complicates translation and optimization. In fact, there has been little research on specific designs for a virtual ISA for processors. This paper proposes a novel virtual ISA (LLVA) and a translation strategy for implementing it on arbitrary hardware.
CO2 injection has recently been shown to provide significant enhanced oil
recovery from naturally fractured reservoirs1. Li et al. (2000) performed CO2
injection at 1750 psig on artificially-fractured cores after water flooding in a
dead-oil system. Gravity drainage was suggested to be the dominant recovery
mechanism in these tests, with significant tertiary oil recovery after water
flooding. The authors observed that the recovery of initial oil at the start of the
CO2 injection declined as the rock permeability decreased and the initial water

In traditional SAS programs, PROCS are called as part of a workflow that usually includes SAS DATA steps along with
PROC steps, which invoke SAS procedures. For example, a very basic SAS program includes a DATA step that creates
the SAS data set from raw data files and a PROC step that invokes an appropriate SAS procedure to process the SAS
A PROC invocation typically takes one or more tables as input and produces a new table as output. Various programming
options and control statements can also be specified on the PROC invocation. These dictate how the PROC...
For the coastal zones of Vietnam, the storm and monsoon waves are considered as the maximum waves for the designed of the marine constructions as sea dyke and other constructions in the coast and in the marine areas. The most challenges are to choose the appropriate storm wave model, to formulate the wind input data set and especially to find the wave data in such utmost dangerous sea state for model validation and for analyzing the forecast results.

AJAX Form Validation
Validating input data is an essential requirement for quality and secure software applications. In the case of web applications, validation is an even more sensitive area, because your application is widely reachable by many users with varying skill sets and intentions. Validation is not something to play with, because invalid data has the potential to harm the application's functionality, and even corrupt the application's most sensitive area: the database.
LABORATORY PROCEDURE I Sampling A. The time division Multiplexer (TDM MUX) module is used to recombine two analog signals into one data stream. The input A is connected to the OUT connector for a period T (T = 1/fs). During the next period, input B is connected to the OUT connector. The process then repeats. It should be obvious that each input, input A(or B) is “Sampled” at a rate equal to ½ fs as set by the Master clock. NOTE: The actual waveform sampling rate = ½ fs as set by the “DATA/Sampling RATE”, output, mentioned above (e.g. to...
The PLAXIS 2D program is a special purpose two-dimensional finite element program
used to perform deformation and stability analysis for various types of geotechnical
applications. Real situations may be modelled either by a plane strain or an axisymmetric
model. The program uses a convenient graphical user interface that enables users to
quickly generate a geometry model and finite element mesh based on a representative
vertical cross section of the situation at hand. Users need to be familiar with the Windows
Introduction to Neural Network Predictive Process Models
In a broad sense, predictive models describe the functional relationship between input and output variables of a data set. When dealing with real-world manufacturing applications, it is usually not an easy task to precisely deﬁne the set of input variables that potentially affect the output variables for a particular process. Oftentimes, this is
A profile is a named set of the following password and resource limits:
Password aging and expiration
Password complexity verification
Input/output (I/O) operations
Memory space (private SQL area for Shared Server only)
After a profile has been created, the database administrator can assign it to each user. If resource limits are enabled, the Oracle server limits the database usage and resources to the defined profile of the user....
Programs written in this functional style are automati-
cally parallelized and executed on a large cluster of com-
modity machines. The run-time system takes care of the
details of partitioning the input data, scheduling the pro-
gram’s execution across a set of machines, handling ma-
chine failures, and managing the required inter-machine
communication. This allows programmers without any
experience with parallel and distributed systems to eas-
ily utilize the resources of a large distributed system.
This paper presents an approach to automatically build a semantic perceptron net (SPN) for topic spotting. It uses context at the lower layer to select the exact meaning of key words, and employs a combination of context, co-occurrence statistics and thesaurus to group the distributed but semantically related words within a topic to form basic semantic nodes. The semantic nodes are then used to infer the topic within an input document. Experiments on Reuters 21578 data set demonstrate that SPN is able to capture the semantics of topics, and it performs well on topic spotting task. ...
This paper introduces a novel hierarchical summarization approach for automatic multidocument summarization. By creating a hierarchical representation of the words in the input document set, the proposed approach is able to incorporate various objectives of multidocument summarization through an integrated framework. The evaluation is conducted on the DUC 2007 data set.
A system, WOLFIE, that acquires a mapping of words to their semantic representation is presented and a preliminary evaluation is performed. Tree least general generalizations (TLGGs) of the representations of input sentences are performed to assist in determining the representations of individual words in the sentences. The best guess for a meaning of a word is the T L G G which overlaps with the highest percentage of sentence representations in which that word appears. Some promising experimental results on a non-artificial data set are presented. ...
