Having located a misspelling, a spellchecker generally offers some suggestions for the intended word. Even without using context, a spellchecker can draw on various types of information in ordering its suggestions. A series of experiments is described, beginning with a basic corrector that implements a well known algorithm for reversing single simple errors, and making successive enhancements t...

In most multi-item inventory systems, the ordering costs consist of a major cost and a minor cost for each item included. Applying for every individual item a cyclic inventory policy, where the cycle length is a multiple of some basic cycle time, reduces the major ordering costs. An e cient algorithm to determine the optimal policy of this type is discussed in this paper. It is shown that this ...

accounting earning represents the positive performance of companies during theirpertinent financial periods, thus it is assumed that accounting earning will benoted by investors, which could contribute to the optimum allocation of resourcesto successful companies. it can also play a major role in the economic growth anddevelopment of a society. this research focuses in the relationship between ...

purpose : to determine add power (ap) and amplitude of accommodation (aa) in a sample of iranian population and its relationship with refractive errors methods : this cross-sectional study enrolled people of 35-70 years old by simple random sampling. exclusion criteria were myopia or hyperopia over 6 diopter (d) and astigmatism more than 0.75 d. those with a history of eye disorders and taking ...

background: the purpose of this work is to discover and analyze errors and incidents in some radiotherapy centers, and to introduce methods that could reduce their occurrences, especially those which had happened due to the use of improper and inadequate equipment. this work is a first step toward clarifying the role of education in a risk-conscious culture, and changing the attitude of radioth...

Background: One way to reduce medical errors associated with physician orders is computerized physician order entry (CPOE) software. This study was conducted to compare prescription orders between 2 groups before and after CPOE implementation in a hospital. Methods: We conducted a before-after prospective study in 2 intensive care unit (ICU) wards (as intervention and control wards) in the larg...

In a recent paper, Soni and Shah [Soni, H., Shah, N. H., 2008. Optimal ordering policy for stock-dependent demand under progressive payment scheme. European Journal of Operational Research 184, 91-100] developed a model to find the optimal ordering policy for a retailer with stock-dependent demand and a supplier that offers a progressive payment scheme to the retailer. This note corrects some e...

The concept of generalized order statistics (GOSs) was introduced as a unified approach to a variety of models of ordered random variables. The purpose of this paper is to investigate condi- tions on the underlying distribution functions and the parameters on which GOSs are based, to establish Shaked-Shanthikumar multivari- ate dispersive ordering of GOSs from one sample and Khaledi-Kochar mu...

In the two-dimensional rotor-router walk (defined by Jim Propp and presented beautifully in [4]), the first time a particle leaves a site x it departs east; the next time this or another particle leaves x it departs south; the next departure is west, then north, then east again, etc. More generally, in any dimension d ≥ 1, for each site x ∈ Z fix a cyclic ordering of its 2d neighbors, and requi...

Naming practices offer a window onto linguistic processes of productivity that rely on input from interacting streams of information. Previous studies have looked at proper personal names and binomial combinations of proper personal names to show that phonological features such as rhythm, semantic features such as gender, and corpus features such as word frequency play an important role in nami...
