The Helmut Schmidt University , located in Hamburg, Germany, is a German military educational establishment that was founded in 1973 at the initiative of the then-Federal Minister of Defence, Helmut Schmidt. Originally known as the "University of the Bundeswehr Hamburg" , its complete official name today is "Helmut-Schmidt-Universität/Universität der Bundeswehr Hamburg". Teaching first started in Autumn of 1973. It is one of two universities that were established by the Bundeswehr to train and educate its future and existing officers. In general, it is accessible only to officers and officer candidates of the Bundeswehr, hence its original name. However, since it started teaching, there have been cooperation agreements with allied countries, on the basis of which a handful of selected officers from these states have been able to study in Hamburg.Since 2002 there has been a small number of civilian students at the university. A prerequisite for studying as a civilian at the Helmut Schmidt University is a business scholarship. These scholarships are usually awarded by foundations with close relationships to industry – thus, these students are at least indirectly being supported by their future employer, usually large companies. As of 2011 training costs are currently 6000 euros , 8000 euros or 10000 euros per academic year.Academic degrees and titles obtained at HSU are equivalent to those awarded by state universities and are equally valid, since the courses comply with the requirements of Hamburg's higher education legislation. The university is authorised to confer habilitations and doctoral degrees. Wikipedia.

Security and quality of life in industrialized countries depend on continuous and coordinate performance of a set of infrastructures (energy systems, ICT systems, transportation etc) which can be therefore defined critical infrastructures (CI). STRUCTURES - Strategies for The impRovement of critical infrastrUCTUre Resilience to Electromagnetic attackS aims at analyzing possible effects of electromagnetic (e.m.) attacks, and in particular of intentional e.m. interference (IEMI), on such CIs, at assessing their impact for our defense and economic security, at identifying innovative awareness and protection strategies and at providing a picture for the policy makers on the possible consequences of an electromagnetic attack. The work is organized into four main tasks, namely: - Scenario assessment (IEMI threat analysis; CIs analysis; modelling and experimental methodologies for investigation) - Investigation (assessment of susceptibility levels of critical systems/units; analysis and testing; innovative protection strategy identification) - IEMI sensors for real-time awareness of threats and implementation of active protection strategies - Delivery of pre-regulatory guidelines to support people in the understanding of IEMI related risk and in planning/application of proper protection strategies. Existing standards such as the Business Continuity Management approach (BS25999 standard) and other standardized CIIP (Critical Information Infrastructures Protection) polices will be considered in order to properly identify critical items and to set criteria for risk acceptance. Already existing results relevant to EMC (ElectroMagnetic Compatibility), LEMP/NEMP/HEMP (Lightning/Nuclear/High altitude ElectroMagnetic Pulse) will be considered as possible starting points leading to find effective solution to IEMI problem. Topological approach, Risk Analysis and 3D modelling tools will be mainly applied for the analysis to a comprehensive set of reference configurations. P

All analysis tools, techniques and diagnostic processes are worthless if the sample fails to effectively represent the actual composition of the mixture to be analyzed. Therefore, correct sampling is indispensable to get meaningful results whereby it is a difficult operation which requires the greatest care in terms of the choice of the sampling point, the way of sampling like sampling by pressure drop or isobaric sampling, the subsequent sample preparation and analysis steps as well as the back coupling of the sampling on the remaining system. In this contribution the focus is set on sampling related to the determination of high-pressure phase equilibria. Thereby the sub-steps and the magnitudes of influence of the sampling procedure on the sample itself as well as on the remaining system, which was investigated on basis of a case study, are discussed in detail. For illustration, many examples from the literature are given. © 2011 Elsevier B.V.


OBJECTIVES:: Perceiving nonbeneficial treatment is stressful for ICU staff and may be associated with burnout. We aimed to investigate predictors and consequences of perceived nonbeneficial treatment and to compare nurses and junior and senior physicians. DESIGN:: Cross-sectional, multicenter paper-pencil survey on personal and work-related characteristics, perceived nonbeneficial treatment, burnout, and intention to leave the job. SETTING:: Convenience sample of 23 German ICUs. SUBJECTS:: ICU nurses and physicians. INTERVENTIONS:: None. MEASUREMENTS AND MAIN RESULTS:: A total of 847 questionnaires were returned (51% response); 778 had complete data for final multivariate analyses. Nonbeneficial treatment was in median perceived “sometimes.” Adjusted for covariates, it was perceived more often by nurses and junior physicians (both p ≤ 0.001 in comparison to senior physicians), while emotional exhaustion was highest in junior physicians (p ≤ 0.015 in comparison to senior physicians and nurses), who also had a higher intention to leave than nurses (p = 0.024). Nonbeneficial treatment was predicted by high workload and low quality collaboration with other departments (both p ≤ 0.001). Poor nurse-physician collaboration predicted perception of nonbeneficial treatment among junior physicians and nurses (both p ≤ 0.001) but not among senior physicians (p = 0.753). Nonbeneficial treatment was independently associated with the core burnout dimension emotional exhaustion (p ≤ 0.001), which significantly mediated the effect between nonbeneficial treatment and intention to leave (indirect effect: 0.11 [95% CI, 0.06–0.18]). CONCLUSIONS:: Perceiving nonbeneficial treatment is related to burnout and may increase intention to leave. Efforts to reduce perception of nonbeneficial treatment should improve the work environment and should be tailored to the different experiences of nurses and junior and senior physicians.

The influence of personality on health related quality of life (QoL) and physical functioning in the setting of allogeneic hematopoietic SCT (alloHSCT) is unknown. We conducted a joint evaluation within two independent cohorts of alloHSCT recipients to investigate the impact of personality on reported QoL and physical functioning. Two-hundred-eight patients (median age 44 years, range 18-72) of cohort 1 and 93 patients (median age 55 years, range 19-79) of cohort 2 after alloHSCT were evaluated. Personality was assessed using the 24-adjective measure (AM), which measures the Big-Five personality domains and the Life Orientation Test-Revised (LOT-R), measuring optimism and pessimism. QoL was measured using the Functional Assessment of Cancer Therapy with bone marrow transplantation subscale (FACT-BMT), Short Form 36 (SF-36), the human activity profile (HAP), as well as the NIH criteria-based cGVHD activity assessment form and the Lee cGVHD symptom scale. Neuroticism was significantly associated with worse function measured by the HAP and FACT-BMT. Optimism significantly improved QoL captured by the FACT-BMT. Pessimism significantly impaired physical function captured by the HAP and SF-36. Extraversion was significantly associated with reduced depression and lower severity of cGVHD symptoms reported by the patient and the physician. The results suggest that personality traits and pre-treatment QoL assessments should be measured in clinical trials to facilitate the interpretation of QoL data.

The correct configuration of the control code is a critical part of every process control system engineering project. To ensure the conformity of the implemented control functions with the customer's specifications, test activities, e.g., the factory acceptance test (FAT), are conducted in every control engineering project. For the past several years, control code tests have increasingly been carried out on simulation models to increase test coverage and timeliness. Despite the advantages that simulation methods offer, the manual effort for generating an applicable simulation model is still high. To reduce this effort, an automated model generation is proposed in this paper. The models automatically generated by this approach provide a modeling level of detail that matches the requirements for the tests of the control code on the base automation level. Therefore, these models do not need to be as detailed as the high-fidelity models which are used for, e.g., model predictive control (MPC) applications. Within this paper, the authors describe an approach to automatically generate simulation models for control code tests based on given computer aided engineering (CAE) planning documents. © 2012 Elsevier Ltd.

In the present contribution an eddy-resolving scheme (large-eddy simulation) is combined with an efficient particle tracking algorithm for individual particles and a deterministic collision model. The purpose is to set-up a reliable methodology for the prediction of complex particle-laden two-phase flows at high mass loadings. The objectives are two-fold. On the one hand the suitability of the entire method to tackle practically relevant turbulent flows should be proven. On the other hand the influence of the fluid-particle interaction (two-way coupling) as well as particle-particle collisions (four-way coupling) is investigated in detail. For both purposes this numerical study is aligned to the experimental investigation of the bluff-body configuration by Borée et al. [J. Borée, T. Ishima, I. Flour, The effect of mass loading and inter-particle collisions on the development of the polydisperse two-phase flow downstream of a confined bluff body, J. Fluid Mech. 443 (2001) 129-165]. In this set-up a fully developed pipe flow laden with polydisperse glass beads enters a cylindrical chamber with an outer annular confined flow without swirl. In contrast to previous numerical studies both mass loadings (η=22% and 110%) and thus also inter-particle collisions are taken into account. Contrary to the experimental investigation the predictions allow to artificially isolate different physical effects in order to clarify their importance. Especially for the high mass loading case interesting new results about the role of fluid-particle interactions and particle-particle collisions are enlightened. © 2012 Elsevier Ltd.

The paper is concerned with the simulation of particle-laden two-phase flows based on the Euler-Lagrange approach. The methodology developed is driven by two major requirements: (i) the necessity to tackle complex turbulent flows by eddy-resolving schemes such as large-eddy simulation; (ii) the demand to predict dispersed multiphase flows at high mass loadings. First, a highly efficient particle tracking algorithm was developed working on curvilinear, block-structured grids. Second, to allow the prediction of dense two-phase flows, the fluid-particle interaction (two-way coupling) as well as particle-particle collisions (four-way coupling) had to be taken into account. For the latter instead of a stochastic collision model, in the present study a deterministic collision model is considered. Nevertheless, the computational burden is minor owing to the concept of virtual cells, where only adjacent particles are taken into account in the search for potential collision partners. The methodology is applied to different test cases (plane channel flow, combustion chamber flow). The computational results are compared with experimental measurements and good agreement is found. © 2012 Elsevier Inc.

The article describes the proposition and application of a local search metaheuristic for multi-objective optimization problems. It is based on two main principles of heuristic search, intensification through variable neighborhoods, and diversification through perturbations and successive iterations in favorable regions of the search space. The concept is successfully tested on permutation flow shop scheduling problems under multiple objectives and compared to other local search approaches. While the obtained results are encouraging in terms of their quality, another positive attribute of the approach is its simplicity as it does require the setting of only very few parameters. The metaheuristic is a key element of the Multi-Objective Optimization and Production Planning Solver MOOPPS. The software has been awarded the European Academic Software Award in Ronneby, Sweden (http://www.bth.se/llab/easa-2002. nsf), and has since been used for research and higher education in the mentioned problem domain (Geiger, 2006). © 2011 Elsevier Ltd.

A portfolio-resampling procedure invented by Richard and Robert Michaud is a subject of highly controversial discussion and big scientific dispute. It has been evaluated in many empirical studies and Monte Carlo experiments. Apart from the contradictory findings, the Michaud approach still lacks a theoretical foundation. I prove that portfolio resampling has a strong foundation in the classic theory of rational behavior. Every noise trader could do better by applying the Michaud procedure. By contrast, a signal trader who has enough prediction power and risk-management skills should refrain from portfolio resampling. The key note is that in most simulation studies, investors are considered as noise traders. This explains why portfolio resampling performs well in simulation studies, but could be mediocre in real life. © 2014, Springer Science+Business Media New York.

Perspective taking plays an important role in different areas of psychological and neuroscientific research. Visual perspective taking is an especially prominent approach generally using one of two experimental tasks: in the own-body-transformation task observers are asked to judge the laterality of a salient feature of a human figure (e.g., is the glove on the left or right hand?) from the figure's perspective. In the avatar-in-scene task they decide about the laterality of objects in a scene (e.g., is the flower on the left or right?) from the avatar's point of view. Increases in latencies and/or errors are interpreted as originating from additional cognitive processes predominately described as observer-based perspective transformations. A closer look reveals that such an account is disputable on grounds related to the use of laterality judgments. Other transformation accounts, i.e., object or array transformations, as well as non-transformational accounts, i.e., extra processing due to spatial conflicts, have not been adequately considered, tested, or ruled out by existing research. Our review examines visual perspective tasks in detail, identifies problems and makes recommendations for future research. © 2013 May and Wendt.
