BACKGROUND The strengths of surgical laparoscopy compared to laparotomy include shorter hospitalization, reduction in post-operative pain and adhesions, and better cosmetic outcomes. Since 2008, Single Port Access Laparoscopy (SPAL) has been used in order to offer additional cosmetic benefits and to further reduce post-operative morbidity. The aim of this study was to assess the feasibility of ...

For any unsatisfiable CNF formula F that is hard to refute in the Resolution proof system, we show that a gadget-composed version of F is hard to refute in any proof system whose lines are computed by efficient communication protocols—or, equivalently, that a monotone function associated with F has large monotone circuit complexity. Our result extends to monotone real circuits, which yields new...

We review some of the key tribological issues of relevance to motorsport applications. Tribology is the science of friction and wear, and in a high performance engine, friction and wear are controlled by good component design (e.g. the engine and the transmission) and also by the use of high performance lubricants with the correct physical (and chemical) properties, matched to the machine they ...

At Fraunhofer IKTS several stationary SOFC system prototypes for biogas usage are currently under development. The prototypes are in the 2 kW range and serve as test beds for innovative, ceramic based system components for a very deep process integration of the SOFC with the biogas generation process. All system components were developed strictly following a model based design process. This con...

This paper reports on our research in developing a micro power generation system based on gas turbine engine and piezoelectric converter. The micro gas turbine engine consists of a micro combustor, a turbine and a centrifugal compressor. Comprehensive simulation has been implemented to optimal the component design. We have successfully demonstrated a silicon-based micro combustor, which consist...

Lattice trapdoors are an important primitive used in a wide range of cryptographic protocols, such as identitybased encryption (IBE), attribute-based encryption, functional encryption, and program obfuscation. In this paper, we present software implementations of the Gentry-Peikert-Vaikuntanathan (GPV) digital signature, IBE and ciphertextpolicy attribute-based encryption (CP-ABE) schemes based...
