Regional and global air pollution emissions from marine transportation is a growing concern. In discerning the sources of such pollution, researchers have become interested in tracking where along the total fuel cycle these emissions occur. In addition, new efforts to introduce alternative fuels in marine vessels have raised new questions about the energy use and environmental impacts of such f...

Although, additive Manufacturing (AM) has been hailed as the “third industrial revolution” by The Economist magazine [April-2012], the first patent on Stereo-lithography was awarded in 1986. An enabling technology which can build, repair or reconfigure components layer by layer or even pixel by pixel with appropriate materials to match the performance will enhance the productivity thus reduce e...

Amedeo Giorgi has asserted that the two key procedures that make psychological research genuinely phenomenological are: 1) the epochés: and 2) the intuition of essence. Giorgi’s insistence on this point is reviewed and the often-misunderstood method of grasping essences is explored. Attention is given to Husserl’s ideas about free imaginative variation and the procedures of eidetic analysis. Ex...

Manufacturing companies in the 21st Century will face unpredictable, high-frequency market changes driven by global competition. To stay competitive, these companies must possess new types of manufacturing systems that are cost-effective and very responsive to all these market changes. Reconfigurability, an engineering technology that deals with cost-effective, quick reaction to market changes,...

In verifying the tolerance specification and identifying the zone of conformity of a particular component an adequate determination of the task-related measurement uncertainty relevant to the utilized measurement method is required, in accordance with part one of the standard “Geometrical Product Specifications” as well as with the “Guide to the Expression of Uncertainty in Measurement”. Althou...

The paper presents the latest results of sensing the cutting process on the basis of AE signals and some particularities in further development of the monitoring model for the finish turning process. Due to non-linearity, the large number of influencing parameters and missing information in AE data, the Artificial Neural Networks were chosen as a monitoring decision tool. The problem of accurat...

Engineering students’ affective self-beliefs prior to their first year have the potential to help researchers better understand various issues related to student retention and engagement. This paper examines whether a neural network model based on student noncognitive characteristics can be used to predict student persistence in engineering, and the influence of gender in the predictive model. ...

The most common stress that living organisms constantly confront in nature is likely to result from temperature changes. Figure 1 shows the temperature changes in Newark, New Jersey during a one year period. The graph shows both average highest and lowest temperatures of each month as indicated by open and solid circles, respectively. One can see that per month there is a difference of approxim...

A short overview is given of recent advances in the field of nanosemiconductors, which are suitable as materials for spin polarized transport of charge carriers. On the basis of last theoretical and experimental achievements it is shown that development of diluted and wide forbidden zone semiconductors with controlled disorders as well as their molecular structures is the very prospective way f...
