We consider the problem of detecting exploits based on return-oriented programming. In contrast to previous works we investigate to which extent we can detect ROP payloads by only analysing streaming data, i.e., we do not assume any modifications to the target machine, its kernel or its libraries. Neither do we attempt to execute any potentially malicious code in order to determine if it is an att

In this paper the surface wave characteristics, as well as the radiation efficiency and the directivity of a patch antenna, with a given current distribution, located on top of an inhomogeneous, isotropic substrate are calculated. The substrate is infinite in the lateral directions and inhomogeneous with respect to the height coordinate. The surface waves in the substrate are analyzed using the pro

Digital Subscriber Lines (DSL) are today one of the most important means for delivering high-speed data transmission. Dynamic Spectrum Management (DSM) is an emerging technique for dealing with crosstalk, one of the technology's most harmful problems. DSM judiciously designs users' power spectral densities so that the overall system performance is improved. This works aims at presenting a new insi

The SEAMLESS project has high ambitions both concerning its scientific goals and its aim to create an impact assessment tool that can be useful in future policy making in the agrienvironmental area. Interaction between researchers and the society therefore is a crucial component of the project. In the last phase of the SEAMLESS project the dissemination of knowledge produced in the project becomes

In the context of growing concerns over climate change and peak oil, biofuels for transport are attracting considerable support from the European Union (EU). However, the sustainability of biofuels is under increasing debate. Furthermore, the complexity of the biofuels industry (involving different resources and feedstock suppliers, different logistics providers and options, a range of technologie

Synthesis of operating procedures for batch plants involves systematic generation of step by step instructions which the operator can implement to manage the batch plant safely and optimally. This is a labor and knowledgeintensive task. It often takes weeks of effort by experts to prepare a clear and error free set of instructions even for a moderately complex plant. If this process is automated,

This work details investigation of two-phase aqueous foam flow, which is applicable for developing energy-efficient heat exchangers. In such heat exchangers, heat transfer rates are enhanced due to the structure and properties of aqueous foam, namely gas bubbles separated by a thin liquid film. Aqueous foam is noted to have an especially large inter-phase contact surface and reduced surface tensio
