D ETECTION OF STATOR FAULT IN SYNCHRONOUS GENERATOR WITHOUT THE KNOWLEDGE OF THE HEALTHY STATE

This paper focuses on the detection of inter-turn s hort circuits which can appear in the stator windings of a salient pole syn chronous generator. A diagnosis method based on two external flux sensors is develo ped. In faulty case, it is shown that variations of reactive power leads to specific variation of sensitive spectral lines in the signals delivered by both sensors. This prop erty allows one to define a diagnostic procedure which does not require the kno wledge of the healthy state.

CENTESIMAL AND MINERAL COMPOSITION , PHENOLIC COMPOUNDS CONTENT AND ANTIOXIDANT CAPACITY FROM PITANGA ( Eugenia uniflora L . ) PULP

This study aims to assess the chemical composition and the antioxidant capacity from pitanga (Eugenia uniflora L.) pulp. The phenolic compounds were extracted from pulp by solid phase extraction and quantified by Folin-Ciocalteu assay. Antioxidant activity (AA) was measured by DPPH, ABTS and FRAP methods. Mineral and centesimal compositions were also determined. Pitanga is a good source of total polyphenols (104.6 mg AGE/100g pulp) and presented AA: (DPPH) 71,2 μmol Trolox/g pulp, (FRAP) 16.74 μmol sulfato ferroso/g pulp and (ABTS) 0.17 μmol Trolox/g of pulp. Pulp presented (g/100g of pulp): 3.68 ± 0.21proteins, 0.02 ± 0.03 lipids, 0.21 ± 0.04 ash, 10,31 ± 00 moisture, 2.06 ± 0.03 carbohydrates and 1,25 ± 0.05 fibers. Calcium was the trace element presented in highest amount (3.36 mg / g pulp). The study highlighted the contribution of phenolic and non-phenolic compounds on antioxidant potential of pitanga.
USABILITY OF TSUNAMI PRA BASED ON ACCIDENTS OF FUKUSHIMA DAI-ICHI NPP UNDER 2011 TOHOKU TSUNAMI

The Tohoku earthquake occurred off the coast of Tohoku district in March 11, 2011 and caused a gigantic tsunami. The tsunami attacked Fukushima Dai-ichi Nuclear Power Plant (F1-NPP) with the wave height that is about 2 times larger than the design basis tsunami wave height. An extreme core damage accident was caused at F1-NPP. On the other hand, as a part of developing Tsunami Probabilistic Risk Assessment (TPRA) method, Japan Nuclear Energy Safety Organization (JNES) has been conducting to identify the accident scenarios of NPP against tsunami event based on TPRA method since 2004. JNES compared and examined the relationship between the above accident scenarios by TPRA and accidents at F1-NPP. The accident scenarios by TPRA more than a year ago identified well about the points occurred at the F1-NPP. It clearly showed further usability of TPRA.
End-To-End and Direct Human-Flying Robot Interaction

As the application domain of Unmanned Aerial Vehicles (UAV) expands to the consumer market and with recent advances in robot autonomy and ubiquitous computing, a new paradigm for human-UAV interaction has started to form. In this new paradigm, humans and UAV(s) are co-located (situated) and use natural and embodied interfaces to share autonomy and communicate. This is in contrast to the traditional paradigm in Human-UAV interaction in which the focus is on designing control interfaces for remotely operated UAVs and sharing autonomy among Human-UAV teams. Motivated by application domains such as wilderness search and rescue and personal filming, we define the required components of end-to-end interaction between a human and a flying robot as interaction initiation (ii) approach and re-positioning to facilitate the interaction and (iii) communication of intent and commands from the human to the UAV and vice versa. In this thesis we introduce the components we designed for creating an end-to-end Human-Flying Robot Interaction system. Mainly (i) a fast monocular computer vision pipeline for localizing stationary periodic motions in the field of view of a moving camera; (ii) a cascade approach controller that combines appearance based tracking and visual servo control to approach a human using a forward-facing monocular camera; (iii) a close-range gaze and gesture based interaction system for communication of commands from a human to multiple flying UAVs using their on-board monocular camera; and (iv) a light-based feedback system for continuous communication of intents from a flying robot to its interaction partner. We provide experimental results for the performance of each individual component as well as the final integrated system in real-world Human-UAV Interaction tests. Our interaction system, which integrates all these components, is the first realized end-to-end Human-Flying Robot Interaction system whereby an uninstrumented user can attract the attention of a distant (20 to 30m) autonomous outdoor flying robot. Once interaction is initiated, the robot approaches the user to close range (≈ 2m), hovers facing the user, then responds appropriately to a small vocabulary of hand gestures, while constantly communicating its states to the user through its embodied feedback system. All the software produced for this thesis is Open Source.
Rapid Heuristic Evaluation: Ensuring Fast and Reliable Usability Support

The U.S. Department of Veterans Affairs (VA) Human Factors Engineering (HFE) office developed a usability testing method called “Rapid Heuristic Evaluation” (Rapid HE) that offers benefits to users of the Agile development process. Rapid HE addresses the need to combine fast, reliable usability support with feedback from clinical subject matter experts (SMEs) during the design and development of an electronic health record (EHR). The Rapid HE process leverages established EHR heuristics to accelerate wireframe review and approval, and merges a traditional heuristic evaluation (HE) with an expert review by two SMEs. Our application of Rapid HEs has maximized use of resources and minimized the amount of time needed to provide feedback during Agile development cycles. This paper describes the Rapid HE process, deviations from traditional HEs, and reports on data from 16 HEs that our group conducted on an EHR platform currently being developed by VA.
Based on Artificial Neural Network to Realize K-Parameter Analysis of Vehicle Air Spring System

In recent years, because of the air-spring control technique is more mature, that air- spring suspension systems already can be used to replace the classical vehicle suspension system. Depend on internal pressure variation of the air-spring, thestiffnessand the damping factor can be adjusted. Because of air-spring has highly nonlinear characteristic, therefore it isn’t easy to construct the classical controller to control the air-spring effectively. The paper based on Artificial Neural Network to propose a feasible control strategy. By using offline way for the neural network design and learning to the air-spring in different initial pressures and different loads, offline method through, predict air-spring stiffness parameter to establish a model. Finally, through adjusting air-spring internal pressure to change the K-parameter of the air-spring, realize the well dynamic control performance of air-spring suspension.
REDUCING THE TECHNOLOGICAL GAP BETWEEN AN ADVANCED PROCESSOR AND THE MEMORY HIERARCHY SYSTEM

This paper discusses dependence collapsing, instruction bypassing and ‘Multiple Load’ issue as advanced mechanisms to improve processor performance in superscalar architectures. We also quantify, by Trace Driven Simulations, the impact on processor performance of associating a Victim Cache/Selective Victim Cache with a first-level cache, both integrated into a parallel architecture.
Numerical Methods for Nonlinear Optimal Control Problems and Their Applications in Indoor Climate Control

OF THE DISSERTATION Numerical Methods for Nonlinear Optimal Control Problems and Their Applications in Indoor Climate Control by Runxin He Doctor of Philosophy in Electrical Engineering Washington University in St. Louis, August 2017 Research Advisor: Humberto Gonzalez Efficiency, comfort, and convenience are three major aspects in the design of control systems for residential Heating, Ventilation, and Air Conditioning (HVAC) units. In this dissertation, we study optimization-based algorithms for HVAC control that minimizes energy consumption while maintaining a desired temperature, or even human comfort in a room. Our algorithm uses a Computer Fluid Dynamics (CFD) model, mathematically formulated using Partial Differential Equations (PDEs), to describe the interactions between temperature, pressure, and air flow. Our model allows us to naturally formulate problems such as controlling the temperature of a small region of interest within a room, or to control the speed of the air flow at the vents, which are hard to describe using finite-dimensional Ordinary Partial Differential (ODE) models. Our results show that our HVAC control algorithms produce significant energy savings without a decrease in comfort. Also, we formulate a gradient-based estimation algorithm capable of reconstructing the states of doors in a building, as well as its temperature distribution, based on a floor plan and a set of x thermostats. The estimation algorithm solves in real time a convection-diffusion CFD model for the air flow in the building as a function of its geometric configuration. We formulate the estimation algorithm as an optimization problem, and we solve it by computing the adjoint equations of our CFD model, which we then use to obtain the gradients of the cost function with respect to the flow’s temperature and door states. We evaluate the performance of our method using simulations of a real apartment in the St. Louis area. Our results show that the estimation method is both efficient and accurate, establishing its potential for the design of smarter control schemes in the operation of high-performance buildings. The optimization problems we generate for HVAC system’s control and estimation are largescale optimal control problem. While some optimal control problems can be efficiently solved using algebraic or convex methods, most general forms of optimal control must be solved using memory-expensive numerical methods. In this dissertation we present theoretical formulations and corresponding numerical algorithms that can find optimal inputs for general dynamical systems by using direct methods. The results show these algorithms’ performance and potentials to be applied to solve large-scale nonlinear optimal control problem in real time.
Spatial and temporal patterns in age and size at maturity and Spawning Stock Biomass of North Sea Gadoids

Demographic traits like growth, maturity and fecundity are plastic in fish. The question is how their variability affects recruitment and population dynamics, and whether it should be taken into account in stock assessment. This paper focuses on variations of age and size at maturity in time and space in four North Sea Gadoid species: cod, whiting, haddock and Norway pout. Data from the International Bottom Trawl Survey (IBTS) in the nine Standard Roundfish Areas of the North Sea for the period 1983-1998 are used. It is shown that there is significant spatial variation in age and size at maturity for cod, haddock and whiting. An index of Spawning Stock Biomass (SSB) is estimated, which takes into account this variability, along with the spatial and temporal variation of fish abundances (also provided by IBTS data). These estimates of SSB are much more variable than those obtained through VPA by stock assessment working groups. In addition, for cod, haddock and whiting, the decreasing trend in SSB is steeper when spatial variations are included. Taking into account the location of spawners improves the prediction of recruitment.

Effective assessment of ecological quality in aquatic ecosystems has become an important issue for researchers and environmental managers worldwide. The potential of thermodynamic oriented ecological indicators in environmental assessment and management was tested and compared with diversity measures in three tropical reservoirs located in the basin of the Paraopeba River, Minas Gerais StateBrazil. We computed Eco-Exergy based indices (Eco-Exergy and Specific Eco-Exergy) and the Margalef and Shannon–Wiener indices and tested differences in their responses to change in benthic communities across reservoirs characterised by different degrees of anthropogenic disturbance. Indices were estimated based on biotic descriptors (macrofauna biomass, composition, and abundance) and their values analysed against abiotic descriptors (pH, conductivity, transparency, turbidity, nutrients concentration, dissolved oxygen, chlorophyll a, and total dissolved solids). The Margalef index showed significant differences between reference and impacted sites, with the highest values in the former type of sites, (Pseudo F2.719 = 24,506, p = 0.001), while the Shannon–Wiener index values showed no significant differences between reference and impacted sites. Eco-Exergy values were significantly higher at stations located in more disturbed sites (Pseudo F2.719 = 80.319, p = 0.001), but Specific Eco-Exergy did not show really significant differences between disturbed and non-disturbed sites, although values were higher in the non-disturbed sites type. This might be explained by the fact that opportunistic tolerant species present high biomass values in polluted sites, since Eco-Exergy values may vary due to changes in biomass or information. On the other hand, differences in information between disturbed and non-disturbed sites were more subtle (although the number of species was higher in the less disturbed sites, it was not clearly reflected in Specific Eco-Exergy values). Our results suggest that thermodynamic oriented indicators can capture coherent structural changes in biological communities, highlighting its indicator potential for assessing the ecological condition/integrity of highly modified water bodies, such as reservoirs. © 2012 Published by Elsevier Ltd.
SOUNDSCAPE CATEGORISATION AND THE SELF-ASSESSMENT MANIKIN

This paper contains the results of a study making use of a set of B-format soundscape recordings, presented in stereo UHJ format as part of an online listening test, in order to investigate the relationship between soundscape categorisation and subjective evaluation. Test participants were presented with a set of soundscapes and asked to rate them using the Self-Assessment Manikin (SAM) and in terms of three soundscape categories: natural, human, and mechanical. They were also asked to identify the important sound sources present in each soundscape. Results show significant relationships between soundscape categorisation and the SAM, and indicate particularly significant sound sources that can affect these ratings.
An Identity-Based Ring Signcryption Scheme in Ideal Lattice

The existing signcryption schemes based on bi-linear pairings were proved to be insecure in quantum computing environment. Lattice is simple in operation, and the difficult problems based on lattice are hard to solve. In order to resist the quantum attack, we presented an identity-based ring signcryption scheme that is provably secure under the standard model by using the Ducas’ ideal lattice technology, which is based on the assumption of the hardness of lattice problem small integer solutions (SIS). This scheme mainly includes four algorithms: Keygen(), Extract(), Signcrypt(), Unsigncrypt(). To some extent, the scheme in this paper that has a high practical value in electronic cash payment system, security certification lightweight authentication and other fields shortens the bytes of private key, public key and the signcryption, improves the operation efficiency. The security of scheme also indirectly ensure the security in electronic cash payment system, security certification and so on.
Pathogenic determination from rural wastewater treated by MBR process and effect of wastewater on lettuce pot planting

Most regions of developing countries use wastewater to irrigate farmlands that alleviate the crisis of water shortage, but to arise numerous potential health risks associate with wastewater irrigation for human and crops. In this study, the microbiological quality of Membrane Bio-Reactors (MBRs) processes of the domestic wastewater treatment plant was assessed by monitoring the concentrations of Aeromonas hydrophila, Arcobacter sp. , Clostridium difficile, Clostridium perfringens, Escherichia coli, Hartmannella vermiformis, Legionella sp. A pot planting experiment is conducted to investigate the persistence of pathogens and impact to vegetables and soils by using different water. The results showed that wastewater slightly impacted physiochemically to soil and vegetable, and the pathogens on vegetables and in soils varied exponentially among different treatments. Compared with controls, pathogens presented in the phyllosphere slightly higher which irrigated with wastewater, whereas no significant difference in the rhizosphere between treated effluent and controls. Accordingly, it is recommended that the treated effluent can be used as an alternative water resource for agricultural irrigation, the variety of pathogens in wastewater should be monitored over an extended period of time. But for the irrigation with untreated wastewater it has health risks.
1 THC / P 401 Shear flow suppression of turbulent transport and self-consistent profile evolution within a multi-scale gyrokinetic framework

The turbulent heat and momentum fluxes obtained from local, nonlinear gyrokinetic simulations with mean toroidal flow are presented. The behavior of the fluxes are characterized by scans in temperature and flow gradient for both zero and finite magnetic shear. Linearly unstable eigenmodes are absent for sufficiently large flow shear, but transient linear growth is found to drive subcritical turbulence whose amplitude increases with flow shear. Consequently, the heat fluxes are minimized at a finite flow shear. By considering the intersection of contours of heat flux (or injected power) and the ratio of momentum to heat flux (inversely proportional to beam energy), bifurcations in the temperature and flow gradients are observed. An analysis is presented showing when such bifurcations are possible and how large the jumps in gradient can be. This zero-dimensional analysis is then extended to the one-dimensional case using the multi-scale transport solver, TRINITY. Using model turbulent fluxes, the plasma performance is found to be optimized at a finite value for the ratio of applied torque to power.
Business planning and beyond ? Qualitative approaches in entrepreneurship

Aim of the Paper: For years, business planning (BP) has held a central role in the new venture creation literature. However, existing research has provided us with mixed results about its usefulness. Part of the argument against BP is that it relies on top-down logic while emerging bottom-up logic may be more relevant. Sarasvathy (2001) proposed that successful entrepreneurs tend to be effectual rather than causal. Sarasvathy & Wiltbank (2002) also suggested that business angels (BAs) and venture capitalists (VCs) tend to be more effectual than causal and should then pay less attention to BP. This paper has two objectives. It first analyses to what extent different kinds of financial backers, i.e. BAs, VCs, and bankers, are generally causal or effectual. Then, it clarifies if entrepreneurs have to prepare different types of the so-called „business plan‟ when they approach different kinds of financial backers and why. Contribution to the literature: This paper advances the literature on the use of BP when entrepreneurs are searching for financial support. It contributes to a better understanding of the expectations of different financial backers and the logic behind their project evaluation process. Methodology: The research is qualitative. It relies on interviews of eight Belgian investors three commercial bankers, three VCs, and two BAs. The interviews followed a systematic and replicable protocol, which included the “venturing experience” developed by Sarasvathy & al. (2001). Results and Implications: Bankers, VCs and BAs follow different logic and have different expectation in terms of business plan. BAs are more effectual than VCs, whereas commercial bankers are more causal. Regarding the content of the business plan, BAs and VCs pay more attention to the entrepreneur, while commercial bankers pay more attention to financials and the plan itself. From a theoretical point of view, the research confirms the importance of adopting a contingent approach when analysing the expectations and behaviour of investors and what they mean by BP. For practitioners, the research contributes to the discussion about the usefulness of BP and confirms that it is not the time to „burn business plans‟ since investors still expect to receive one. However, the results suggest that it is time to reconsider the way we analyse the new venture preparation process and its outcome as a „business plan‟ since the effectual logic is central for many investors.
Factors influencing intra-partum midwifery malpractices at tertiary hospitals in Tshwane, Gauteng Province, South Africa

Midwifery malpractices occurring during intra-partum care are on the rise. Of all the cases reported to the South African Nursing Council (SANC) in 2013, 47% were midwifery-related and this percentage increased to more than 50% in 2014. The consequences of such misconduct are devastating to the affected women if they live, and to their families as well as the health system. Almost all investigated cases of misconduct would have been avoided if acceptable standards of care had been applied. Disciplinary measures imposed on midwives because of errors, include suspension from practice or being struck off the register or sent for retraining. The aim of this study was to explore and describe the factors influencing midwifery malpractice during intra-partum care at two tertiary hospitals. Thirteen participants were purposively selected and were interviewed up to data saturation point. Thematic data analysis was employed. Factors contributing to midwifery malpractice were categorised according to three themes: external factors, personal factors and administrative factors. Findings revealed a fair share of transgressions amongst midwives, but vicarious liability in respect of the hospital administration exists. Error identification through continuous auditing of maternal files and the implementation of corrective measures is urgently required. Patient interviews could also shed more light on this phenomenon.
