The use of building simulation within an architectural practice

This paper documents the development and implementation and use of simulation within an architectural practice and reports how its use facilitates the practice's commitment to Sustainable Design

Experience of using building simulation within the design process of an architectural practice

This paper documents work that follows on from a previous study [Morbitzer et al 2001] on the implementation of a simulation-tool into anarchitectural practice at outline design stage. Theuse of simulation is now pervasively and routinely undertaken by designers within the company toevaluate energy and environmental performance oftheir design concepts. The paper documents the changes to the interface, based on the feedback from designers. It includes a case study of how these improvements have impacted on the degree-of-use of the simulation tool by designers, the impact of the tool on the design process and the design outcome, a discussion on the development of the simulation tool, and the issues facing the architectural practice with use of simulation

Application of data mining techniques for building simulation performance prediction analysis

Simulation exercises covering long periods (e.g.. annual simulations) can produce large quantities of data. The result data set is often primarily used to determine key performance parameters such as the frequency binning of internal temperatures. Efforts to obtain an understanding for reasons behind the predicted building performance are often only carried out to a limited extent and simulation is therefore not used to its full potential. This paper describes how data mining can be used to enhance the analysis of results obtained from a simulation exercise. It identifies clustering as a particular useful analysis technique and illustrates its potential in enhancing the analysis of building simulation performance predictions

Integration of building simulation into the design process of an architectural practice

A key barrier to the acceptance of simulation within building design has been identified as the fact that it is not fully integrated into the design process. The project described in this paper attempts to address this barrier by embedding modelling as a standard component of design practice procedures within an architectural practice

Extracting Secrets from Encrypted Virtual Machines

AMD SEV is a hardware extension for main memory encryption on multi-tenant systems. SEV uses an on-chip coprocessor, the AMD Secure Processor, to transparently encrypt virtual machine memory with individual, ephemeral keys never leaving the coprocessor. The goal is to protect the confidentiality of the tenants' memory from a malicious or compromised hypervisor and from memory attacks, for instance via cold boot or DMA. The SEVered attack has shown that it is nevertheless possible for a hypervisor to extract memory in plaintext from SEV-encrypted virtual machines without access to their encryption keys. However, the encryption impedes traditional virtual machine introspection techniques from locating secrets in memory prior to extraction. This can require the extraction of large amounts of memory to retrieve specific secrets and thus result in a time-consuming, obvious attack. We present an approach that allows a malicious hypervisor quick identification and theft of secrets, such as TLS, SSH or FDE keys, from encrypted virtual machines on current SEV hardware. We first observe activities of a virtual machine from within the hypervisor in order to infer the memory regions most likely to contain the secrets. Then, we systematically extract those memory regions and analyze their contents on-the-fly. This allows for the efficient retrieval of targeted secrets, strongly increasing the chances of a fast, robust and stealthy theft.Comment: Accepted for publication at CODASPY 201

Edukacja wspierana komputerowo a humanistyczne wartości pedagogiki

Celem niniejszej pracy jest ukazanie złożoności zagadnienia edukacyjnych zastosowań mikrokomputera, a w szczególności pokazanie jego powiązań z humanistycznymi wartościami pedagogiki. Bez postrzegania tego tak bardzo dziś istotnego i powszechnego, a często zredukowanego do praktycznego wymiaru problemu, w bogactwie kontekstów: oczywistym i naturalnym – pedagogicznym oraz technicznym, a także psychologicznym, społecznym, aksjologicznym, kulturowym, filozoficznym, historycznym, a nawet politycznym, stosowany w edukacji komputer staje się kolejnym narzędziem, używanym bez refleksji, a przez to nie tylko nie przyczyniającym się do polepszenia efektywności kształcenia, ale wręcz tworzącym różnorodne nowe patologie i zagrożenia oraz pogłębiającym informacyjny zalew. Do najważniejszych elementów refleksji niezbędnej dla edukacyjnie poprawnego wykorzystywania komputerów należy zaliczyć dostrzeganie różnic między dostępną w bazach danych i Internecie informacją a potrzebną człowiekowi do własnego rozwoju i przez niego tworzoną wiedzą. Istotne jest także ukazanie sposobów przekształcania informacji w wiedzę, a – w miarę możliwości – w dalszych etapach kształcenia także w mądrość, rozumianą – między innymi – jako umiejętność podejmowania trafnych decyzji i zdolność przewidywania rozmaitych konsekwencji własnych działań
