This paper presents the mechanical modifications and simulation of a bipedal humanoid system actuated with linear springs to produce a standing equilibrium position. The original humanoid system is comprised of two leg assemblies connected by a hip bracket. Eleven pairs of springs were attached to the system in locations designed to simulate the muscles and tendons in a human body. The next evolution of the LUIGEE project is the inclusion of three servo motors per leg and a series of elastomeric springs. Although servo motors have been introduced, it is desired to maintain the passive, static aspect of the previous prototype. This paper reports on part modifications to accommodate servo motors and the introduction of polymeric springs that guarantee static stability. ABS plastic and photopolymer resin was used to produce the new model. Due to the size of the motors, some parts of the original robot were redesigned. The new design iteration was stimulated using SimWise 4D®, where the hysteretic effect of rubber was modelled with an equivalent viscous damping.

Appearance Models

We propose a new model-based recognition method that involves the use of three-dimensional (3D) ellipsoidal models in various sizes and proportions as well as their two-dimensional (2D) appearance models. Most model-based vision is intended to recognize specified objects, and the model is specific to the object. However, our method can recognize various proportions of objects and was applied in posture estimation of the human body from thermal images.

Can we really trust the things our bodies tell us about the world? This work reveals how deeply intertwined cultural practices of art and science questioned the authority of the human body in the late eighteenth and early nineteenth centuries. Focusing on Henry Fuseli, Anne-Louis Girodet and Philippe de Loutherbourg, it argues that romantic artworks participated in a widespread crisis concerning the body as a source of reliable scientific knowledge. Rarely discussed sources and new archival material illuminate how artists drew upon contemporary sciences and inverted them, undermining their founding empiricist principles. The result is an alternative history of romantic visual culture that is deeply embroiled in controversies around electricity, mesmerism, physiognomy and other popular sciences. This volume reorients conventional accounts of romanticism and some of its most important artworks, while also putting forward a new model for the kinds of questions that we can ask about them.

Current models for the origin of writing do not pay sufficient attention to the origin and early development of means adopted by modern humans to record, transmit and process information outside the human body. The present article attempts to fill this gap by elaborating a theoretical model able to classify and describe the variability of these systems. The model is applied to the study of the engraved antler from La Marche, one of the better-known Palaeolithic objects to have been interpreted as an early system of notation. Technical analysis of the marks, through application of a range of experimental criteria, suggests that the sets of marks carved on this object should be interpreted as an artificial memory system with a complex code based on the morphology and the spatial distribution of the engraved marks. These results have important implications for current theories on the origin of writing.

The authors reconsider the origins of metallurgy in the Old World and offer us a new model in which metallurgy began inc. eleventh/ninth millennium BC in Southwest Asia due to a desire to adorn the human body in life and death using colourful ores and naturally-occurring metals. In the early sixth millennium BC the techniques of smelting were developed to produce lead, copper, copper alloys and eventually silver. The authors come down firmly on the side of single invention, seeing the subsequent cultural transmission of the technology as led by groups of metalworkers following in the wake of exotic objects in metal.

Design Variables

The effect of design features of an internal spinal fixator under loading is critical to understanding of interaction between fixator and instrumented spine. In this study, we performed finite element analysis for spinal pedicle screw installed in the lumbar spine. The purpose of this study is to model and simulate the newly designed spinal pedicle screw. The deformation and stress of the screw are analyzed for the tightening process and loading process simulating the condition when it is installed in the human body as described in the ASTM F1717 procedure. We expected this study is to derive reliable results for developing a new model by analysis of design variables and fatigue behavior.
