Chile is one of the main exporters of sweet cherries in the world and one of the few in the southern hemisphere, being their harvesting between October and January. Hence, Chilean cherries have gained market in the last few years and positioned Chile in a strategic situation which motivates to undergo through a deep innovation process in the field. Currently, cherry crop estimates have an error of approximately 45%, which propagates to all stages of the production process. In order to mitigate such error, we develop, test and evaluate a deep neural-based approach, using a portable artificial vision system to enhance the cherries harvesting estimates. Our system was tested in a cherry grove, under real field conditions. It was able to detect cherries with up to 85% of accuracy and to estimate production with up to 25% of error. In addition, it was able to classify cherries into four sizes, for a better characterization of the production for exportation.

This chapter aims to illustrate the importance that learning trajectories and the building of technological capabilities have had in the internationalization and competitiveness process of the nowadays Multinational Companies from an Emerging Economy (MCEE), based on the case of CEMEX, a Mexican multinational and one of the largest cement companies of the world. The case study shows that the emergence of this company into the global markets is the result of a mix of assets and capabilities (Penrose, 1995; Bell & Pavitt, 1995; Bell, 2007) developed over a period of nearly eight decades, at whose base are productive, technological and organizational capabilities. Findings substantiate that multinationalization through mergers and acquisitions has strengthened the technological capabilities of CEMEX, as a result of the learning and knowledge sharing processes driven by the actual integration of CEMEX with the acquired companies. By establishing learning routines, CEMEX feeds an innovation process within the group.

Rubber Filler

Large volumes of agricultural and food processing residues are generated daily around the world. Despite the various potential uses reported for this biomass, most are still treated as waste that requires disposal and negatively impacts the environmental footprint of the primary production process. Increasing attention has been paid toward the use of these residues as alternative fillers for rubber and other large-scale commodity polymers to reduce dependence on petroleum. Nevertheless, characterization of these alternative fillers is required to define compatibility with the specific polymer, identify filler limitations, understand the properties of the resulting composites, and modify the materials to enable the engineering of composites to exploit all the potential advantages of these residue-derived fillers.

The Relationship

In recent years, the concept of entrepreneurship has become very important in ensuring social welfare and economic development and attracts attention as the driving force of economic development and social welfare. Because of these reasons, studies on entrepreneurship find support from all over the world, and in the universities, besides studies supporting the entrepreneurship, also related courses are featured. The concept of entrepreneurship is investigated in this research, and personality traits observed in entrepreneurs such as need for achievement, self-confidence, risk taking, innovativeness, creativity, locus of control, tolerance of uncertainty are tried to explain. The relationship between enterprising tendency and self-confidence trait, as well as innovation and creativity are given. Also, innovation process and types are explained, and the significance of entrepreneurial creativity and its measurement is tried to explain through a case study.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Deformation Patterns

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
