An autonomous robot inspired by insect neurophysiology pursues moving features in natural environments

Objective. Many computer vision and robotic applications require the implementation of robust and efficient target-tracking algorithms on a moving platform. However, deployment of a real-time system is challenging, even with the computational power of modern hardware. Lightweight and low-powered flying insects, such as dragonflies, track prey or conspecifics within cluttered natural environments,

Role of Correlations in the Collective Behavior of Microswimmer Suspensions

In this Letter, we study the collective behavior of a large number of self-propelled microswimmers immersed in a fluid. Using unprecedentedly large-scale lattice Boltzmann simulations, we reproduce the transition to bacterial turbulence. We show that, even well below the transition, swimmers move in a correlated fashion that cannot be described by a mean-field approach. We develop a novel kinetic

Bipolar Photothermoelectric Effect Across Energy Filters in Single Nanowires

The photothermoelectric (PTE) effect uses nonuniform absorption of light to produce a voltage via the Seebeck effect and is of interest for optical sensing and solar-to-electric energy conversion. However, the utility of PTE devices reported to date has been limited by the need to use a tightly focused laser spot to achieve the required, nonuniform illumination and by their dependence upon the See

Hierarchical Self-Organizing Maps System for Action Classification

We present a novel action recognition system that is able to learn how to recognize and classify actions. Our system employs a three-layered hierarchy of Self-Organizing Maps together with a supervised neural network for labelling the actions. We have evaluated our system in an experiments consisting of ten different actions from a publicly available data set. The results are encouraging with 83%

Spectacular, realisable and ‘everyday’ : Exploring the particularities of sustainable planning in Malmö

‘Sustainability’, often presented through an ecological–economic–social triad, is today one of spatial planning’s absolute key concepts (and key priorities). But it is also a highly contested concept, whose meaning is often considered evasive or vague. In this paper, we try to counterweigh such evasiveness by putting emphasis on the material landscape produced within a project that is frequently d

Public procurements and social clauses after the Laval quartet some comparative remarks

Among all the different ways used by the social State to promote higher labour standards the public procurements have always played an important role. Exploiting them economic attractiveness, in fact, most Countries used to insert in them several types of social clauses, so to oblige the awarded tenderer to grant a broad series of rights to the employees involved in the execution of the procuremen

What local people? Examining the Gállok mining conflict and the rights of the Sámi population in terms of justice and power

The global extraction of minerals is commonly located in areas populated by indigenous people; and while conflicts between multinational corporations and local activists and indigenous people are widespread today, the understanding of their dynamics are lacking. The Swedish government’s encouragement to an expanding mining industry has caused resistance due to environmental and social implications

På okänt cancervatten - närståendes perspektiv

Samtidigt som alltfler drabbas av cancer ökar överlevnaden. Det betyder att fler lever med en cancerdiagnos. De närstående ökar i antal och deras insatser för samhället och den enskilde är stora medan behoven i liten grad står utforskade. Genom kvalitativa utforskande intervjuer av närstående till cancersjuka har vi sökt förstå de närståendes upplevelser av sin roll. Berättelserna har visat en spr

Så kan vårt beteende styras smartare

Nudging är ett användbart verktyg för att påverka beteenden. Vi bör dra nytta av dess möjligheter att uppnå resultat utan de tvång och begränsningar för individen som traditionella metoder medför, skriver sex experter på beteendepåverkan.

The underlying dimensions of brand orientation and its impact on financial performance

This research responds to the need for an increased understanding of brand orientation and its impact on financial performance. Since brand orientation is often perceived as a somewhat elusive concept we here present a theoretical framework for the purpose of identifying the underlying dimensions of brand orientation from a holistic perspective. Based on this framework we have performed a study onThis research responds to the need for an increased understanding of brand orientation and its impact on financial performance.

From market orientation to brand orientation in the public sector

This conceptual article examines brand orientation as an alternative to market orientation in the public sector. The problem with market orientation is that the focus on customers is too great; it is myopic, and lacks true interaction; it is mechanistic, and the emphasis on economic values is too strong. In this light, brand orientation becomes an interesting alternative. Brand orientation is more
