Suspension system performance optimization with discrete design variables
2013
Published version of an article in the journal: Structural and Multidisciplinary Optimization. Also available from the publisher at: http://dx.doi.org/10.1007/s00158-013-0888-7 Suspension systems on commercial vehicles have become an important feature meeting the requirements from costumers and legislation. The performance of the suspension system is often limited by available catalogue components. Additionally the suspension performance is restricted by the travel speed which highly influences the ride comfort. In this article a suspension system for an articulated dump truck is optimized in sense of reducing elapsed time for two specified duty cycles without violating a certain comfort th…
Driver Situation Awareness and Perceived Sleepiness during Truck Platoon Driving–Insights from Eye-tracking Data
2021
Truck platoon driving technology uses vehicle-to-vehicle communication to allow one truck to follow another in an automated fashion. The first vehicle is operated manually, the second vehicle is dr...

Glycoprotein A repetition predominant (GARP), a specific surface molecule of activated regulatory T cells, has been demonstrated to significantly contribute to tolerance in humans by induction of peripheral Treg and regulatory M2-macrophages and by inhibition of (tumorantigen-specific) T effector cells. Previous work identified GARP on Treg, and also GARP on the surface of several malignant tumors, as well as in a soluble form being shedded from their surface, contributing to tumor immune escape. Preliminary results also showed GARP expression on brain metastases of malignant melanoma. On the basis of these findings, we investigated whether GARP is also expressed on primary brain tumors. We…

The presence and interaction of immune cells in the tumor microenvironment is of significant importance and has a great impact on disease progression and response to therapy. Hence, their identification is of high interest for prognosis and treatment decisions. Besides detailed phenotypic analyses of immune, as well as tumor cells, spatial analyses is an important parameter in the complex interplay of neoplastic and immune cells—especially when moving into focus efforts to develop and validate new therapeutic strategies. Ex vivo analysis of tumor samples by immunohistochemistry staining methods conserves spatial information is restricted to single markers, while flow cytometry (disrupting t…
A mathematical model of the self-averaging Pitot tube
2005
Abstract Flowmeters with self-averaging Pitot tubes are more and more often applied in practice. Their advantages are practically no additional flow losses, usability in the case of high temperature of fluids and simplicity of fitting. A mathematical model of a self-averaging Pitot tube including the influence of the probe shape, selected constructional features and flow conditions on the quantity of differential pressure gained has been given in this paper. The values and ranges of variations of the coefficients established for the model have been assessed on the basis of the numerically computed velocity and pressure fields around and inside the probe. Velocity and pressure fields were ca…
A cultural comparison study of smartphone adoption in Uzbekistan, South Korea and Turkey
2017
Smartphone popularity is increasing due to the technological advances that mean manufacturers can make more sophisticated devices, and telecommunication companies can provide better connections. Gartner reported that 403 million smartphones were sold in the fourth quarter of 2015, a 9.7% increase over the same period in 2014. It is a common perception that users tend to utilise advanced technology to increase productivity. However, there are studies indicating quite opposite or alternatively slow rates of adoption. To avoid this, companies invest in studying consumer behaviour. The purpose of the study is to examine the effects of drivers and cultural differences on smartphone acceptance in…

The Political Click: Political Participation through E-Petitions in Germany
2010
Electronic petitions can serve as an influential mechanism for political participation. We present a study on the dynamics in the German e-petition system which was introduced in late 2008. Drawing on a data set of signatures, we analyze four aspects: (a) the types of petitions found, (b) the temporal dynamics of petitions, (c) the types of users found, and (d) the intersection of different petitions' supporter populations. We present evidence that (a) the system is dominated by a very small number of high-volume petitions and (b) these high-volume petitions have a delayed boosting effect on the base activity in the petition system. We furthermore (c) present a typology of users, showing th…
The heterogeneity of services and the differential effects on business and territorial innovation
2011
The innovative results of firms depend upon their specific characteristics and their ability to weave together their competences with the innovative resources in their environment. Different approaches have underlined the importance of location and the context of business innovation. In particular, the existence of knowledge intensive services (KIS) enables firms to create and commercialise new processes, products and services. However, KIS can present substantial differences in their capacity to contribute to innovation. This article examines the relationship between KIS and business innovation and establishes a KIS typology in order to pinpoint its effects on business innovation. The resu…
