This personal reflection of more than 40 years' work on the supply of labour in a household context discusses the relationship between social science history (the application to historical phenomena of the tools developed by social scientists) and local population studies. The paper concludes that historians working on local source materials can give something new back to social scientists and social science historians, urging them to remake their tools.

The interest in actuators based on dielectric elastomer films as a promising technology in robotic and mechatronic applications is increasing. The overall actuator performances are influenced by the design of both the active film and the film supporting frame. This paper presents a single-acting actuator which is capable of supplying a constant force over a given range of motion. The actuator is obtained by coupling a rectangular film of silicone dielectric elastomer with a monolithic frame designed to suitably modify the force generated by the dielectric elastomer film. The frame is a fully compliant mechanism whose main structural parameters are calculated using a pseudo-rigid-body model and then verified by finite element analysis. Simulations show promising performance of the proposed actuator.

Collective Enterprise

Let me begin with a simple theme, repentance, and a simple message: repent from complacency in the practice and defense of social science history (SSH). I say this because I do not see social science historians meeting three major challenges that must be overcome if the larger, collective enterprise is to survive with the same vitality it had a decade ago. Those challenges are, first, to bring social theory forcefully back into historical research; second, to take formal methods to a new, higher level; and, third, to seek to train the next generation of social science historians in the theory and methods they will need in the next century.

AbstractAugmented, mixed and virtual reality are changing the way people interact and communicate. Five dimensional communications and services, integrating information from all human senses are expected to emerge, together with holographic communications (HC), providing a truly immersive experience. HC presents a lot of challenges in terms of data gathering and transmission, demanding Artificial Intelligence empowered communication technologies such as 5G. The goal of the paper is to present a model of a context-aware holographic architecture for real time communication based on semantic knowledge extraction. This architecture will require analyzing, combining and developing methods and algorithms for: 3D human body model acquisition; semantic knowledge extraction with deep neural networks to predict human behaviour; analysis of biometric modalities; context-aware optimization of network resource allocation for the purpose of creating a multi-party, from-capturing-to-rendering HC framework. We illustrate its practical deployment in a scenario that can open new opportunities in user experience and business model innovation.
