Demand forecasting is one of the important activities in a supply chain which provides all the supply chain planning processes with market information crucial for efficient supply chain management. Its performance is measured by forecasting error, which is defined using the difference between forecast and actual sales. In this paper, we classify the forecasting error types based on the cases th...

In this work, we address the problem of spelling correction in the Arabic language utilizing the new corpus provided by QALB (Qatar Arabic Language Bank) project which is an annotated corpus of sentences with errors and their corrections. The corpus contains edit, add before, split, merge, add after, move and other error types. We are concerned with the first four error types as they contribute...

Video compression enables a number of applications by reducing the required bit rate needed to represent a video sequence, however the compressed video is much more susceptible to errors such as bit errors or packet loss. Conventional video compression standards employ an architecture which we refer to as single-state systems since they have a prediction loop with a single state (e.g. the previ...

Abstract We consider an M/G/1 feedback queue with optional server vacations based on Bernoulli schedule and a single vacation policy. We assume that the server provides two types of service, type 1 with probability p1 and type 2 with probability p2 with the service times following general distribution and each arriving customer may choose either type of service. However after the completion of ...

BACKGROUND Medication error (ME) is a worldwide issue, but most studies on ME have been undertaken in developed countries and very little is known about ME in Southeast Asian countries. This study aimed systematically to identify and review research done on ME in Southeast Asian countries in order to identify common types of ME and estimate its prevalence in this region. METHODS The literatur...

The issue of whether or not to correct errors in students’ writing is controversial. Some scholars argue that error correction is helpful, while others argue that it is ineffective, perhaps even harmful. What is missing from the literature are studies about how error correction might affect the performance of specific types of students. This study, which included 140 undergraduate English major...

Quantzzat~on can effectively reduce the huge amount of data with possibly small error (called quantzzatton error). In designing a quantizer using a portion of the data as a training data , the training algorithm tries to find a codebook that minimizes the quantization error measured in the training data. I t is known that , under several conditions, the minimized quantizat.ion error approaches ...
