Several research studies have shown the importance of physical exercise. The global gym and fitness industry faced a transition from traditional gyms to virtual fitness training during the pandemic lockdowns. A proliferation of applications is available to provide different digital gym experiences. Advagym is one example that uses sensors to track and give feedback to gym goers. Sony's R&D Cen

Energy conservation plays a vital role towards sustainable development of meat processing. Energy costs for many meat plants represent the fourth highest operational cost. In meat processing, moderate levels of both electrical and thermal energy are consumed in wide range of processes and applications. However, energy efficiency improvement in the meat processing industry have been a focus to incr

We prove the existence of three-dimensional steady gravity-capillary waves with vorticity on water of finite depth. The waves are periodic with respect to a given two-dimensional lattice and the relative velocity field is a Beltrami field, meaning that the vorticity is collinear to the velocity. The existence theory is based on multi-parameter bifurcation theory.

We present a fabrication scheme of contacting arrays of vertically standing nanowires (NW) for LEDs (Duan et al. Nature 409:66–69, 2001), photodetectors (Wang et al. Science (NY) 293:1455–1457, 2001) or solar cell applications (Wallentin et al. Science (NY) 339:1057–1060, 2013). Samples were prepared by depositing Au films using nano-imprint lithography (Ma rtensson et al. Nano Lett 4:699–702, 200

Identification of cancer subtypes is the central goal in the cancer gene expression data analysis. Modified symmetry-based clustering is an unsupervised learning technique for detecting symmetrical convex or non-convex shaped clusters. To enable fast automatic clustering of cancer tissues (samples), in this chapter, the authors propose a rough set based hybrid approach for modified symmetry-based

This paper describes and discusses the development of mobile exergames for children with cerebral palsy. The design process was built on co-design, and resulted in three activity games, two augmented reality (AR) games and one GPS based game. The resulting activity games were evaluated by 8 per-sons with cerebral palsy (CP). To complement this evaluation, the games have been evaluated against exis

Fully localised solitary waves are travelling-wave solutions of the three- dimensional gravity–capillary water wave problem which decay to zero in every horizontal spatial direction. Their existence has been predicted on the basis of numerical simulations and model equations (in which context they are usually referred to as ‘lumps’), and a mathematically rigorous existence theory for strong surfac

The U.S. counterinsurgency – symbolised by the omnipresent killing eye of drones – as it expands from the battlefield to the monitor, is criticised for inaugurating a geographically unbounded war that subjects the everyday life of a population to wartime targeting calculation. We, however, claim that the significant feature of the so-called new technologies of looking and targeting is in their abi

We present a microchannel-based adaption of density-gradient centrifugation that allows the instantaneous, precise, and repeatable generation of a 1-dimensional mass-density gradient and determination of single-cell densities with integrated mass-density calibration.
