Digitalisering av socialt arbete kräver kraftsamling

Socialtjänsten. Det finns flera nyttor med att digitalisera det sociala arbetet; det sänker exempelvis tröskeln för kommunikation med socialtjänsten. Vår nya kunskapsöversikt på området pekar på utmaningar, bland annat juridiska, och möjliga vägar framåt. Samhället är redan i hög grad digitaliserat, då måste den offentliga förvaltningen måste följa med.

The influence of native language word order and cognitive biases in pictorial event representations

Ever since Goldin-Meadow, S., C. Mylander, W. C. So, and A. Özyürek. 2008. The natural order of events: How speakers of different languages represent events nonverbally. PNAS 105: 9163–9168. proposed that there is a preferred order in sequential non-verbal event representations (Actor > Patient > Act), apparently independent of the default word order in one’s native language, the topic has been th

Haptic Perception with a Robotic Hand

Abstract in UndeterminedWe have developed an 8 d.o.f. robot hand which has been tested with three computational models of haptic perception. Two of the models are based on the tensor product of different proprioceptive and sensory signals and a self-organizing map (SOM), and one uses a novel self-organizing neural network, the T-MPSOM. The computational models have been trained and tested with a s

Characterising the vulnerability of linear control systems under sensor attacks using a system's security index

We introduce the 'security index' of a discrete-time, linear time-invariant system under sensor attacks as a quantitative representation-free measure on the vulnerability of an observable system. Ideas from linear coding theory are employed in providing conditions for attack detection and correction in terms of a system's security index, along with methods for its computation based on different re

Associating SOM Representations of Haptic Submodalities

We have experimented with a bio-inspired selforganizingtexture and hardness perception system whichautomatically learns to associate the representations of the twosubmodalities with each other. To this end we have developeda microphone based texture sensor and a hardness sensor that measures the compression of the material at a constant pressure. The system is based on a novel variant of the Self-

Power converters for the magnets of the Linac Warm Units of ESS

ESS, the European Spallation Source, will be a major user facility at which researchers from academia and industry will investigate scientific questions using neutron beams. ESS will deliver its protons to a solid, rotating tungsten target, which will in turn generate neutrons. A linear accelerator (Linac) creates protons at the ion source, accelerates them to an appropriate energy and steers them
