The main conclusions are:
1. Initial imperfections have very little influence on girder resistance. The worst analyzed imperfection with the amplitude of h_W/100 deviate by 3.5% from the value obtained for perfect geometry.
2. Girders with high slenderness showed little interaction in the area of high bending and shear loads. Compared to EN 1993-1-5 the results were found to be conservative, except for very few cases, but then gross cross-section check at the support governs.
3. For girders with lower slenderness the interaction rule in EN 1993-1-5 was found to be unsafe. Also in these cases the gross cross-section control dominates.
4. Generally the cross-section control according to clause 4.6 (3) of EN 1993-1-5 was found to be more severe than interaction buckling control.
5. The M-V interaction formula proved to be more conservative for lower bending moments and higher slenderness.

I have tried to clarify in the paper the role of organizational learning (OL) and knowledge management (KM). For this reason I have theoretically studied all the characteristics of the OL process. On this bases I have then identified the key factors which significantly impact the OL process. I have empirically tested the relevance of the identified factors. Through theoretical study and empirical tests, I have shown that the right organization of a company presents the key mechanism that supports/impedes the OL process. For this reason OL has to become the focus of KM efforts.

The ever-increasing demand of energy in the society and the simultaneous need to provide that with renewable sources (with often intermittent character) calls for new solutions for balancing the demand and supply. Improved energy storage solutions offer a good option. The ongoing work in a European project, STORY, aims at demonstrating and evaluating innovative approaches for energy storage systems. The challenge is to find solutions, which are affordable, secure and ensure an increased share of self-supply. The project includes eight different demonstration cases each with different local or small-scale storage concepts and technologies, covering industrial and residential environments. These demonstrations feed into a large-scale impact assessment, with the aim to show the added value storage can bring for a flexible, secure and sustainable energy system. Each of the demonstrations brings a different technology, context or business case. STORY is now at the end of its second year of action, and the results from the first year are available. These include definition of the main grid challenges to be addressed by storage solutions and specification of the requirements for the hardware and software elements that will be applied in the demonstrations and simulations. In parallel, during the first year, the installations on the demo sites were realised or preparatory work was conducted on the sites. The IT architecture was defined and optimized for each demonstration site. To enable monitoring of the results, the partners also defined the measurement protocols and the related Key Performance Indicators. One significant result was the definition of a three-level architecture for the control system. The grid simulation scenarios were chosen based on thorough studies of the local environment and availability of data. The definition of the business models started in co-operation with the other storage and smart grid projects funded in the same series of H2020 calls.

Despite the success that standard ISO 9001:1994 achieved it was extensively criticized and empirical studies showed controversial results about its impact on performance. The standard went through important changes in year 2000; however the empirical research related to results of ISO 9001:2000 did not show a very optimistic picture either. In 2008 standard was again moderated, this time changes were modest though. Our conceptual study was motivated with the above mentioned dilemma about ISO 9001 effectiveness, and the controversy that this dilemma raises in literature on one side and on the other side with the almost exponential growth of certifications among companies world-wide. It is our opinion that in order to understand results related to ISO 9001 implementation we need to take a step back from empirical research and instead try to analyze ISO conceptually by taking into account also the results of empirical studies implemented in the past. Paper analyzes changes in the focus of standard and their consequences with using a specific framework of the presented operations strategy theory. The purpose of our paper is to conceptually analyze what are the consequences for ISO 9001 standardization, as the revised standard emphasized most known TQM elements by drawing upon a conceptual theoretical and empirical research base, developed within operations strategy research on one side, and on the other side on an extensive empirical research basis related to implementation issues and benefits of ISO 9001:1994 and 9001:2000. Paper proposes two different possible interpretation of the ISO 9001:2000/2008 purpose and identifies consequences and dilemmas of accepting each of the interpretations. Analysis shows that the present version of ISO is not consistently structured and therefore ISO committee has to overcome this ambiguity by clearly stating what the purpose of the ISO 9001 is and structure the standard consistently in accordance with this stated purpose. Analysis shows that there are different possible theoretical options of how to respond to identified shortcomings of the ISO 9001:2000, which are relevant based on the specific interpretation of what has been the actual intended change in standard’s purpose.
