Biogeography-based optimization (BBO) is a new evolutionary optimization method that is based on the science of biogeography. We propose two extensions to BBO. First, we propose a blended migration operator. Benchmark results show that blended BRO outperforms standard BBO. Second, we employ blended BRO to solve constrained optimization problems. Constraints are handled by modifying the BRO immi...

Blended learning environments are now the norm in most information systems schools. Blended learning environments are constantly changing as a wide array of technical and social influences bear upon our universities and colleges. This study describes a widely based literature review of the blended learning environment, particularly as it pertains to information systems teaching and learning as ...

One of the major drawbacks of IC engines is low efficiency and pollution resulting from incomplete combustion. In order to improve the emission properties and performance an oxygenated additive MTBE (Methyl tertiary butyl ether), is blended with gasoline. A four cylinder, 1817 cc engine was used for analysing both emission and performance characteristics. Tests were carried out with 100% pure g...

Introduction There is a demand for more attractive and efficient training programmes in postgraduate health care training. This retrospective study aims to show the effectiveness of a blended versus traditional face-to-face training design. For nurses in postgraduate Acute and Intensive Care training, the effectiveness of a blended course design was compared with a traditional design. Methods I...

The development of information technology is able to solve problems in various areas of life, including education. Some examples of the application of information technology in education, among others: e-learning, e-library, e-module, blended learning, and more. One school in Bali that also apply information technology in the learning process, namely SMK TI Udayana. Application forms of informa...

Uniformly sampled images are often used to interpolate other data acquired more sparsely with an entirely different mode of measurement. For example, downhole tools enable geophysical properties to be measured with high precision near boreholes that are scattered spatially, and less precise seismic images acquired at the earth’s surface are used to interpolate those properties at locations far ...

This study investigates engineering student preferences for blended learning adoption in higher education. No major study to date, however, has taken into consideration the influence of interaction, digital technology, social presence, and internet self-efficacy on student preferences for blended learning approach. This study is based on a sample of 126 students who can use Moodle platform at U...

The purpose of this article is to develop a design theory of blended learning curriculum in ways of establishing a model for designing such a curriculum and a model for designing an activity in a blended learning curriculum as well as demonstrating how these models can be utilized in a curriculum design. It first attempts to define what the essence of blended learning is by drawing on definitio...

Treating sentiment analysis as a classification problem has proven extremely useful, but it misses the blended, continuous nature of sentiment expression in natural language. Using data from the Experience Project, we study texts as distributions over sentiment categories. Analysis of the document collection shows the texts contain blended sentiment information substantially different from a ca...
