Originally, three versions of the all-composite aircraft were envisioned, one powered by piston engines, one by turboprops and one by turbofans. The flight test characteristics of composites pdf was completed and confirmed the targeted performance. The financial situation of Beech at the time, and competing projects, prevented consideration of commercial production.

In February 1991, Rutan stated, “it had the potential for enormous improvements in efficiency compared to the King Air. After the test program was completed, the airframe was mounted on a pedestal at Scaled’s Mojave facility for several years. Coulsdon, UK: Jane’s Defence Data, 1990.

The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2016 to the previous five years and divided by the source items published in the previous five years. SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field. SJR is a prestige metric based on the idea that not all citations are the same. This application lets readers explore data and other quantitative results submitted with the article, providing insights into and access to data that is otherwise buried in plots.

Publishing your article with us has many benefits, such as having access to a personal dashboard: citation and usage data on your publications in one place. This free service is available to anyone who has published and whose publication is in Scopus. The word cement is interpreted in a wide sense, including not only Portland cement but also blended cements and other binding materials. Provided there is sufficient linkage to properties defined at the material scale, papers concerning the behavior of structural components and systems, in situ performance, and field studies will also be accepted for review, as well as those concerning the repair and maintenance, serviceability behavior, and sustainability of structures made with these materials. The journal has within the above context several specific objectives. It is the intention of the journal to also publish special issues devoted to topics of current or emerging interest.

The journal aims to provide a unifying basis for collaboration between materials scientists, engineers, designers and fabricators.

Topic 3: Are attractive faces only average? In the 1800s, Sir Francis Galton created composite images of faces by projecting face photographs of many different individuals onto a single piece of photographic film. While Galton aligned the constituent images using the distance between the pupils, causing the images to appear somewhat fuzzy, these more modern computer graphic methods warp each of the constituent faces into the average shape for the sample before blending the images together. This process ensures that the images created are sharper than those created using Galton’s methods. In other words, many researchers that had noted the high attractiveness of composite faces proposed that averageness is the critical determinant of attractiveness.

In a classic study of facial attractiveness, Perrett et al. Averageness Hypothesis in an effort to establish if averageness really is the critical determinant of the attractiveness of faces. 15 faces that had been judged to be the most attractive by the first group of participants. 60 faces and the composite of the most attractive 15 faces using computer graphic methods. This is noteworthy because the hyper attractive face was mathematically the least average of all 3 composites. Because the hyper-attractive face was the least average of the 3 composites judged, but also the most attractive, this finding is very strong evidence that averageness is not necessarily the critical determinant of facial attractiveness. Choose how many images to average together and see if more average faces really are more attractive and if the average of attractive faces is more attractive than the average of faces not selected for attractiveness.
