Geotechnical analysis of heat exchanger piles

Lyesse Laloui, Hervé Péron, Christoph Knellwolf

There is currently a lack of established calculation method for the geotechnical design of heat exchanger piles, although the technology is experiencing a fast expansion. Instead of quantifying the effects of temperature changes on the static behavior of h ...

Traffic Effects of the Emergency Lane Use

Sofia Samoili

The use of the hard shoulder/emergency lane (EL) is analysed in the current research, with case study the first experimental application of emergency lane use undertaken in Switzerland (Morges - Écublens). The EL is activated during peak hours and when con ...

Effects of Radiation on MEMS

Herbert Shea

The sensitivity of MEMS devices to radiation is reviewed, with an emphasis on radiation levels representative of space missions. While silicon and metals generally do not show mechanical degradation at the radiation levels encountered in most missions, MEM ...

Modelling the influence of human behaviour on the spread of infectious diseases: a review

Marcel Salathé

Human behaviour plays an important role in the spread of infectious diseases, and understanding the influence of behaviour on the spread of diseases can be key to improving control efforts. While behavioural responses to the spread of a disease have often ...

New Perspectives on the Evaluation of Public R&D Funding

Any economic criteria for an efficient allocation of resources is based on marginal “thinking”. Such criteria can equally be applied to the evaluation of the public allocation of R&D funds. Differently from the usual evaluation schemes - mainly dichotomous ...

Surface DBD’s and plasma-flow interaction

Christoph Hollenstein, Peter Ott, Pénélope Leyland, Philip Peschke, Sami Goekce, Samantha Pavon

Surface Dielelectric Barrier Discharges (DBD) are becoming very attractive in the field of flow control technologies for their promising effects on stabilising separating flows, at least at low speeds under the so-called ionic wind effect. Numerous experim ...

A circuit-level substrate current model for smart-power ICs

Maher Kayal, Jean-Michel Sallese, François Krummenacher, Marc Pastre, Fabrizio Lo Conte

This paper presents a new modeling methodology accounting for generation and propagation of minority carriers that can be used directly in circuit-level simulators in order to estimate coupled parasitic currents. The method is based on a new compact model ...

Experimental Measurement of Monovalent Cation Adsorption onto Bacillus subtilis Cells

Daniel Scott Alessi

Typically, the effects of ionic strength on metal adsorption to geosorbents are accounted for by models of the surface electric field, assuming a planar surface. However, bacterial cell walls are not two-dimensional surfaces. Furthermore, electric field mo ...

Hopping and trapping mechanisms in organic field-effect transistors

Libero Zuppiroli, Marie-Noëlle Bussac, Steven Konezny

A charge carrier in the channel of an organic field-effect transistor (OFET) is coupled to the electric polarization of the gate in the form of a surface Fröhlich polaron [N. Kirova and M. N. Bussac, Phys. Rev. B 68, 235312 (2003)]. We study the effects of ...

Large Shareholders and Corporate Policies

Rüdiger Fahlenbrach

We analyze the effects of heterogeneity across large shareholders, using a new blockholder-firm panel dataset in which we can track all unique blockholders among large public firms in the United States. We find statistically significant and economically im ...
