Automated subjective answer assessments in modern digital evaluation environments are promising structural consistency, but they distort the very nature of expressing complex and contextrich information put up for evaluation. In modern teachinglearning environments, with wide variety of biasing observed while fabricating humane scripted Memoranda-Of-Instructions, it becomes difficult to evaluat...

Research has revealed that biblical Christianity is declining as a life-ordering force among American Christian youth (Barna Group, 2009; Ham & Beemer, 2009; Smithwick, 2008). This trend continues despite the ubiquitous references to terms like biblical integration and biblical worldview in Christian school mission statements. In fact, from its inception, the evangelical Christian school moveme...

In this work a pilot project of Learning Management System (LMS), used in high school to complement the traditional teaching-learning process, is showed. The LMS used is Atutor, opensource-software based in learning objects (LO) and SCORM compliant. The Virtual High School (VHS) was implemented in a traditional Chilean high school, following the software engineering procedure, the first step wa...

The paper discusses yet another approach of clustering datasets whose cluster numbers are not known beforehand. The suggested approach effectively determines the number of clusters or partitions while running the algorithm. The proposed method is only limited to partitional clustering inspired from the K-means algorithm. In this work a Modified TeachingLearning-Based Optimization (MTLBO) is use...

The aim of our research is developing educational software to assist teachinglearning process from elementary schools to college. We argue that all educational environments have to concern about pedagogical aspects in order to guarantee better quality for students and teachers activities during the educational process support by educational software. To achieve this we must to observe some guid...

This paper argues that design and usability issues are of great importance on technology-based implementation and evaluation programs, as they can have both a positive and a negative impact on teaching-learning processes. For instance, the quality of the design can aid the development of new reasoning skills on the one hand, and on the other it can affect the understanding of physical phenomena...

in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...

in the present work, multidimensional modeling of open-cycle process of om355 engine was developed. calculations for computational mesh were carried out. the results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. results included pressure, temperature, emission a...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...
