An efficient synthesis of Methyl 2-[2-(alkylimino)-4-oxo-3-phenyl-1,3-thiazolan-5-yliden]acetate derivatives via simple three-component reaction and one-pot reactions between isoquinoline, dimethyl acetylenedicarboxylate and N-phenylthiourea under solvent-free conditions without using any additional catalyst, is described. The mild reaction conditions and good yields and exhibit the synthetic a...
The approach to phonological comparison adopted in UPSID as well as other studies fails to recognize the abstract nature of even the most phonetically based definition of a phonemic system. Phonemes receive a simple phonetic translation based on one allophone. Phonological comparison is therefore carried out using no more than arbitrary selections of the phonetics of the languages involved. Pho...
Recommender systems help users sort through vast quantities of information. Sometimes, however, users do not know if they can trust the recommendations they receive. Adding a confidence metric has the potential to improve user satisfaction and alter user behavior in a recommender system. We performed an experiment to measure the effects of a confidence display as a component of an existing coll...
The Computer registration of physical and mechanical quantities gives a lot of possibilities of machine elements and mechanisms research. The advantages of well-organized computer laboratory both technical and methodological, namely: Registration and on-line observation of a number of processes with random speed; replacement of high-cost specialized laboratory equipment; mathematical data proce...
Within the training community at large, a revolution has taken place over the past decade. Advances in Virtual Reality (VR) technology have created an environment in which traditional training pedagogies, which focus on static, one-size-fits-all approaches, are being supplanted with broad-scale, dynamic, interactive, and multi-modal approaches to learning. Two key factors driving these changes ...
As modern industry shifts toward significant globalization, robust and adaptable network capability is increasingly vital to the success of business enterprises. Large quantities of information must be distilled and presented in a single integrated picture in order to maintain the health, security and performance of global networks. We present a design for a network situational awareness displa...
In this chapter, an innovative model for age replacement is proposed. The costs included in the age replacement model are not assumed to be constants. For effective optimization of statistical decisions for age replacement problems under parametric uncertainty, based on a past random sample of lifetimes, the pivotal quantity averaging (PQA) approach is suggested. The PQA approach represents a s...
