In this paper we shall consider a well-known transmission model: information source —coder —channel —decoder, supposing that both the coder and the decoder are finite automata. Naturally, we shall suppose, that our automata will be of the general type, which will not preserve the length of the input words. Then there are some difficulties in estimating the transmission quality which would not o...

To preserve legacy systems in continuous software development and evolution, next to redevelopment, they can be migrated to new environments and technologies. Deciding on evolution and migration strategies early, requires predicting the quality of the migrated software systems depending on applied tools. There is a need for comparable measures, estimating the inner software quality of legacy an...

Motivated by the problem of out-of-shelf (OOS) in retail industry and the emergence of RFID (Radio Frequency Identification) technology, this paper investigates the impact that the adoption of RFID has on the quality of information utilized during the shelf replenishment process. A RFID-integrated information system (IS) with three alternative implementation scenarios is proposed to enhance the...

Innovation is fundamental for economic catching-up and raising living standards. Evidence demonstrate a virtuous circle in which R&D spending, innovation, productivity, and per capita income mutually reinforce each other and lead to long-term, sustained growth rates and may foster job creation. Previous evidence highlights that Latin America and the Caribbean (LAC) has great potential to benefi...

Image fusion is the process by which input images are fused in order to increase the quality. The input images must be the images of the same scene with different quality measures. The quality of the output image will be better than any of the input images. The main methods of the image fusion involve simple image fusion, pyramid based image fusion and wavelet based image fusion. Image fusion m...

Machine translation (MT) technology is becoming more and more pervasive, yet the quality of MT output is still not ideal. Thus, human corrections are used to edit the output for further studies. However, how to judge the human correction might be tricky when the annotators are not experts. We present a novel way that uses cross-validation to automatically judge the human corrections where each ...

In most modern manufacturing systems, products are often the output of some multistage processes. In these processes, the stages are dependent on each other, where the output quality of each stage depends also on the output quality of the previous stages. This property is called the cascade property. Although there are many studies in multistage process monitoring, there are fewer works on prof...

We characterize the optimal procurement contract in a setting where a supplier has privileged knowledge of the quality of a public signal about his production costs. The optimal contract exhibits important differences with standard contracts in adverse selection settings. For instance, the contract induces output both above and below first-best levels. Furthermore, the induced output may not va...
