Evidence of prosthetic use can be dated back to the second Punic War [1]. However, state-of-the-art devices have advanced very little, especially for individuals who need forearm and hand functionality, and have little financial support for high-end, custom robotic devices. This is particularly the case for military veterans. The prosthetics prescribed are thermally hot, heavy in weight, fit poorly, restrict mobility and are unattractive. This paper will review how the aforementioned design challenge was addressed through 3D body scanning and rapid prototyping technologies, for an undergraduate product design student’s capstone project.

Computer-Aided Ergonomics (CAE) makes it possible that people may build a virtual environment for ergonomics evaluation in the product’s digital model phase. Manikin with anthropometry data supplies fundamental information in design lifecycle, so it also plays an important role in CAE software. Thanks to the 3D scanning technology, we developed a new ergonomics manikin generation method which could create free-form surface human model from real body. Generation method concluded body scanning, model optimization, and combining skeleton stages. Finally, case study proved that Paper’s method could generate more exact manikin than former parametric modeling methods, and it would benefit customized products design.

In this research project an independent case study on the new contactless 3D body measuring native mobile applications has been carried out. The presented approach allows combination of three different measurement methods: the manual body measuring with the help of traditional instruments, 3D full body scanning technology and the contactless body measuring via smartphone applications. This paper discusses results of the investigation of usability of the measurement process via 3D body scanning apps on the Gage R&R methodology and the examination of their measuring accuracy. The current research provides analysis of body data obtained by the mobile scanning apps with the help of various methods.

Abstract Three-dimensional body scanning systems are increasingly used in sensitive public areas such as airports. By providing a high resolution image of a person from all sides, it is possible to detect potential metallic, ceramic and explosive threats. For these systems, it is essential to design broadband antennas with a fan beam, highly directional radiation in one plane and wide in the other plane, and characterized by phase center stability as a function of frequency. In this paper, the planar lateral wave antenna (LWA) array is proposed to achieve these radiation requirements. The LWA has two critical shortcomings: the flaring part and the dielectric matching layers (MLs), to operate over very broad frequency bands. In this work, these shortcomings are overcomed by forming a connected array of planar LWAs to improve broadband performance and by applying necessary perforations on the dense dielectric lens antenna to create different effective relative permittivity regions. An eight element connected and perforated LWA array is designed to operate in the 8–24 GHz frequency band. The drilled holes are proved to play a similar critical role of MLs in internal reflection suppression. The results emphasize all crucial demands for body scanning systems.

Since the early beginning of the development of the 3-D digital human and ergonomics tool RAMSIS in 1988, appropriate measurement systems had been developed simultaneously. New integrated approaches and methods for human body measurement have been investigated and developed. TECMATH has developed the VITUS Pro and VITUS Smart 3-D Full Body Laser Scanner family for high precision, and adapted a 2-D video camera-based system that is simple to use and inexpensive. In the past three years, novel applications for mass customization have been developed specifically for the clothing industry. More than 120 systems (3-D and 2-D) have been installed in research environments, clothing shops, army facilities and automobile manufacturers in the past two years. These organizations require measurement systems, methods, and analysis techniques that ensure reliable and precise information about human body dimensions.

The Genesis and Internal Dynamics of El Salvador's People's Revolutionary Army, 1970–1976

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

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.
