Neuartiges Modell des Querverhaltens von FFZ-Reifen

Die dynamische Standsicherheit ist beim Betrieb eines Gegengewichtsgabelstaplers eine entscheidende Größe. Diese wird neben der Position des Gesamtschwerpunktes und den geometrischen Abmaßen wesentlich von den Reifeneigenschaften bestimmt. Ein neues Rechenmodell der Super-Elastik-Reifen ermöglicht genauere Simulationen, tiefere Einblicke in das dynamische Verhalten der Fahrzeuge bei der Auslegung und somit bessere dynamische Standsicherheit.

Untersuchungen Gewichtsreduktionspotentiale Gegengewichtsgabelstapler

Die Masse eines Gegengewichtstaplers beeinflusst den Energieverbrauch beim Fahren maßgeblich. Steigende Energiepreise und steigendes Umweltbewusstsein führen zu grünen Trends in Logistik. Durch Reduktion der Gesamtmasse eines Gabelstaplers können große Einsparungen erreicht werden. Eine Machbarkeitsstudie soll mithilfe der numerischen Simulationen zeigen, dass neuartige Fahrzeuge mit aktiven Systemen trotz geringerer Masse hinreichend hohe Standsicherheit aufweisen können. In diesem Beitrag sollen die ersten Ergebnisse dieses Forschungsvorhabens vorgestellt werden.

Modulares Prognosemodell für den einsatzspezifischen Energieverbrauch von Gabelstaplern

Flurförderzeuge leisten einen wesentlichen Beitrag zu den Treibhausgasemissionen in der EU. Aktuell wird ihr Verbrauch in Deutschland in der Regel per VDI-Zyklus prognostiziert. Dieser hat allerdings keinen Bezug zu dem tatsächlichen Nutzungsprofil eines konkreten Flurförderzeugs. Es soll untersucht werden, inwiefern ein modularer Aufbau, der sich einsatzspezifisch anpassen lässt, eine verbesserte Prognose der Verbräuche ermöglicht. Zudem soll analysiert werden, wie viel Mehraufwand diese verbesserte Möglichkeit der Vorhersage für die Hersteller bzw. die Nutzer bedeutet. Am MTL ist ein Messsystem aufgebaut worden, welches neben dem Energieverbrauch auch die Einflussparameter aufnimmt. Es werden exemplarische Messungen vorgestellt.

Citizen journalism and everyday life : A case study of Germany’s myHeimat.de

Much recent research into citizen journalism has focussed on its role in political debate and deliberation. Such research examines important questions about citizen participation in democratic processes – however, it perhaps places undue focus on only one area of journalistic coverage, and presents a challenge which only a small number of citizen journalism projects can realistically hope to meet. A greater opportunity for broad-based citizen involvement in journalistic activities may lie outside of politics, in the coverage of everyday community life. A leading exponent of this approach is the German-based citizen journalism Website myHeimat.de, which provides a nationwide platform for participants to contribute reports about events in their community. myHeimat takes a hyperlocal approach but also allows for content aggregation on specific topics across multiple local communities; Hannover-based newspaper publishing house Madsack has recently acquired a stake in the project. Drawing on extensive interviews with myHeimat CEO Martin Huber and Madsack newspaper editors Peter Taubald and Clemens Wlokas during October 2008, this paper analyses the myHeimat project and examines its applicability beyond rural and regional areas in Germany; it investigates the question of what role citizen journalism may play beyond the political realm.

Citizen Consultation from Above and Below : The Australian Perspective

In Australia, a range of Federal Government services have been provided online for some time, but direct, online citizen consultation and involvement in processes of governance is relatively new. Moves towards more extensive citizen involvement in legislative processes are now being driven in a “top-down” fashion by government agencies, or in a “bottom-up” manner by individuals and third-sector organisations. This chapter focusses on one example from each of these categories, as well as discussing the presence of individual politicians in online social networking spaces. It argues that only a combination of these approaches can achieve effective consultation between citizens and policymakers. Existing at a remove from government sites and the frameworks for public communication which govern them, bottom-up consultation tools may provide a better chance for functioning, self-organising user communities to emerge, but they are also more easily ignored by governments not directly involved in their running. Top-down consultation tools, on the other hand, may seem to provide a more direct line of communication to relevant government officials, but for that reason are also more likely to be swamped by users who wish simply to register their dissent rather than engage in discussion. The challenge for governments, politicians, and user communities alike is to develop spaces in which productive and undisrupted exchanges between citizens and policymakers can take place.

From Prosumer to Produser: Understanding User-Led Content Creation

Alvin Toffler’s image of the prosumer (1970, 1980, 1990) continues to influence in a significant way our understanding of the user-led, collaborative processes of content creation which are today labelled “social media” or “Web 2.0”. A closer look at Toffler’s own description of his prosumer model reveals, however, that it remains firmly grounded in the mass media age: the prosumer is clearly not the self-motivated creative originator and developer of new content which can today be observed in projects ranging from open source software through Wikipedia to Second Life, but simply a particularly well-informed, and therefore both particularly critical and particularly active, consumer. The highly specialised, high end consumers which exist in areas such as hi-fi or car culture are far more representative of the ideal prosumer than the participants in non-commercial (or as yet non-commercial) collaborative projects. And to expect Toffler’s 1970s model of the prosumer to describe these 21st-century phenomena was always an unrealistic expectation, of course. To describe the creative and collaborative participation which today characterises user-led projects such as Wikipedia, terms such as ‘production’ and ‘consumption’ are no longer particularly useful – even in laboured constructions such as ‘commons-based peer-production’ (Benkler 2006) or ‘p2p production’ (Bauwens 2005). In the user communities participating in such forms of content creation, roles as consumers and users have long begun to be inextricably interwoven with those as producer and creator: users are always already also able to be producers of the shared information collection, regardless of whether they are aware of that fact – they have taken on a new, hybrid role which may be best described as that of a produser (Bruns 2008). Projects which build on such produsage can be found in areas from open source software development through citizen journalism to Wikipedia, and beyond this also in multi-user online computer games, filesharing, and even in communities collaborating on the design of material goods. While addressing a range of different challenges, they nonetheless build on a small number of universal key principles. This paper documents these principles and indicates the possible implications of this transition from production and prosumption to produsage.
