The next speaker in this session was Dr. Cliff Davidson from Carnegie Mellon University s Environmental Institute. Davidson divided his talk into four topic areas (1) skills and attitudes that future engineers will need (2) environment across the curriculum initiative (3) case studies in green engineering and (4) center for sustainable engineering A three-university consortium comprising Carnegie Mellon, University of Texas at Austin, and Arizona State University. 

The results presented here focus on the present and future effect on radiative forcing due to changes in the radiatively-important chemical species (03, water vapor and CHJ associated with aircraft emissions. To address this question, we conduct uncoupled model experiments using the University of Oslo (UiO) 3-D chemical transport models (CTMs) to calculate changes in atmospheric composition and the State University of New York at Albany (SUNYA) 3-D global climate model (GCM) to calculate the radiative forcing associated with these changes. Two case studies were conducted to... 

This book is divided into two parts. Part 1 covers the materials science of military textiles and equipment, and Part 11 is about the application and case studies. Eaeh of the chapters discusses the state of the art as well as future trends. 

It is hoped that this report would serve as a useful guide for future case studies which can be undertaken with the Agency s assistance by Member States with definitive plans for nuclear power programme. 

The paper is organized as follows In section 2 we state the problem of quantitative risk assessment studied in the paper. In section 3 we provide a description of the modeling framework, the approach we take to modeling cyber-attacks on ICS and a brief description of the case study used to illustrate the approach. Section 4 summarizes our findings, section 5 - the related research. Finally, section 6 concludes the paper and outlines directions for future research. 

In this paper, a method of software safety verification at the system level based on STPA is proposed. We investigated the application of the STPA structure to software, and we found that STPA can be directly used for software. We mapped the results of the STPA safety analysis to a formal specification to be able to verify safety requirements at the software code level. The limitation of the method is that the formal specification is done manually which may lead to much effort to construct and check the potential combinations of relevant states. Therefore, we are exploring the automation of this step and integrate it with our A-STPA tool as future work. Furthermore, we plan in-depth case studies to improve the method by applying it to real safety-critical software in industry. We plan also to investigate the effectiveness of using the proposed method during an ISO 26262 life cycle in the automotive industry. 

The paper is organized as follows. Section 2 presents the state of the art and highlights the current limitations of existing approaches for sequences assessment. Section 3 introduces the theoretical framework of the probabilistic languages (Garg et al. 1999) and the used notations. In section 4 is introduced the case study which is used like a support for the rest of the paper. Section 5 develops a theoretical framework based on probabilistic languages for quantitative assessment of events sequences. This proposed approach is illustrated using the case study in the section 6. Finally, section 7 presents the conclusions of this work and identifies some future research directions. 

This paper deals with the PSA level-1 studies of a nuclear system with the possibility of recovery of some failed units during accident progressions. A scheme of PSA level-1 studies with the combination of partially dynamic repairable event tree and repairable fault tree is introduced. The quantification of repairable fault tree is performed based on the concept of up-time and down-time ratio for steady state system. A case study on the PSA of ASTRID DHR system with an initiating event is performed and found that repair of some units within the grace period during accident progression can reduce the CDF considerably. In future works, the proposed scheme would be implemented using dynamic reliability methods with the considerations of common cause failures and non-linear failure behaviors. 

An industrial evaluation of the methodology on realistic case studies is currently ongoing within the COMPASS project. This will provide substantial insights on the applicability of the proposed methodology and the effectiveness of the tool chain. Of particular interest is the verification of reactive systems modeling continuous dynamics. In the future, we plan to systematically investigate the combination of symbolic model checking techniques for the effective construction of the state space to scale up quantitative and probabilistic analyses.
