Der volle Inhalt der QuelleNeisseria meningitidis (the meningococcus), the causative agent of meningococcal disease (MD) was identified in 1887 and despite effective antibiotics and partially effective vaccines, Neisseria meningitidis (N. meningitidis) is the leading cause worldwide of meningitis and rapidly fatal sepsis usually in otherwise healthy individuals. Over 500 000 meningococcal cases occur every year. These numbers have made bacterial meningitis a top ten infectious cause of death worldwide. MD primarily affects children under 5 years of age, although in epidemic outbreaks there is a shift in disease to older children, adolescents and adults. MD is also associated with marked morbidity including limb loss, hearing loss, cognitive dysfunction, visual impairment, educational difficulties, developmental delays, motor nerve deficits, seizure disorders and behavioural problems. Antimicrobial peptides (AMPs) are molecules that provide protection against environmental pathogens, acting against a large number of microorganisms, including bacteria, fungi, yeast and virus. AMPs production is a major component of innate immunity against infection. The chemical properties of AMPs allow them to insert into the anionic cell wall and phospholipid membranes of microorganisms or bind to the bacteria making it easily detectable for diagnostic purposes. AMPs can be exploited for the generation of novel antibiotics, as biomarkers in the diagnosis of inflammatory conditions, for the manipulation of the inflammatory process, wound healing, autoimmunity and in the combat of tumour cells. Due to the severity of meningitis, early detection and identification of the strain of N. meningitidis is vital. Rapid and accurate diagnosis is essential for optimal management of patients and a major problem for MD is its diagnostic difficulties and experts conclude that with an early intervention the patient’ prognosis will be much improved. It is becoming increasingly difficult to confirm the diagnosis of meningococcal infection by conventional methods. Although polymerase chain reaction (PCR) has the potential advantage of providing more rapid confirmation of the presence of the bacterium than culturing, it is still time consuming as well as costly. Introduction of AMPs to bind to N. meningitidis receptors could provide a less costly and time consuming solution to the current diagnostic problems. World Health Organization (WHO) meningococcal meningitis program activities encourage laboratory strengthening to ensure prompt and accurate diagnosis to rapidly confirm the presence of MD. This study aimed to identify a list of putative AMPs showing antibacterial activity to N. meningitidis to be used as ligands against receptors uniquely expressed by the bacterium and for the identified AMPs to be used in a Lateral Flow Device (LFD) for the rapid and accurate diagnosis of MD.

In this study, we explore the impact of gene-based patents on the pricing and availability of genetic diagnostic tests. We also explore the nature and scope of the genetic diagnostics industry itself. Through data mining of the GeneTests database and gathering of pricing and procedure information from over 51 laboratories (using a range of sources including phone interviews), we created a unique database that links pricing, procedure and availability information for each sequencing-based gene diagnostic test offered in the US. In addition, we linked relevant gene-based patents to each gene in our database. Our results indicate a correlation between gene patents and test pricing, with an average non-patented test price of -$1330.31 (121 entries) compared to an average price of -$1419.58 for tests associated with gene patents (137 entries).

Der volle Inhalt der QuelleThe work carried out in this thesis concerns the design of robust nonlinear observers with model uncertainties as weIl as unknown inputs. The developed methods concern a class of a nonlinear systems represented by a multiple model. The stability conditions of the proposed observers are formulated using exclusively the second method of Lyapunov and its formulation in Linear Matrix Inequality (LMI) form. The synthesized observers can be grouped into two categories: The first one is based on explicitly eliminating the effect of the unknown inputs (disturbance of additive nature) in state estimation error. However, this approach is unpractical when the considered multiple model is subject to parametric uncertainty (disturbance of multiplicative nature). The second category attempts to handle the difficulties encountered previously. The underlying principle is to compensate the effects of the different disturbances. This is achieved by introducing the concept of sliding mode, which is robust against the model uncertainties, in the observer structure. The developed observers are used to implement sensor and actuator fault detection and isolation pro- cedure for the class of nonlinear systems represented by a multiple model. For this purpose, we have adapted and transposed the existing fault detection and isolation methods developed in the context of the linear models. The efficiency of the proposed methodology is verified through an interesting application of turbojet engine described by a multiple model

Der volle Inhalt der QuelleThe purpose of reinforcing assemblies and structural elements inwood is to overcome the resistance limits of the material, by transferring greaterefforts in areas which can lead to premature cracking in structures. The reinforcementsused can be made of steel, composite materials or wood. Their hook can bemechanical (screwed bodies) or by adhesion (structural bonding like glued-in rodsfor example). In both cases, the transfer of solicitations remains poorly known, andthe effect of the beginning and the deflection of crack are not well apprehended. Inengineering techniques, the wood resistance in the reinforced area is neglected, whichis in line with the precautionary principle. Currently, the scientific investigations areinterested in the resistance of those kind of techniques without considering the interactionsbetween the quasi-brittle behavior of the wood and the reinforcementswhich govern the gain in mechanical performance. However, these solutions can leadto a failure caused by the progressive splitting of the wood and the anchor loss ofthe reinforcement. So it seems accurate to propose predictions of the short-termstrength for splitting of reinforced and unreinforced beams, which can be used tofurther exploration of the long-term failure mechanism. That is why, in this study, aglobal prediction model of the ultimate strength of structural components subjectedto splitting, reinforced and unreinforced ones, was developed. It considers the quasibrittlebehavior of the wood and crack propagation in mixed mode, using a mixinglaw established on the R-curves. The relevance of this modeling was then comparedto the current dimensioning methods of the Eurocodes 5, for notched beams, withexperimental campaigns conducted at different scales

Der volle Inhalt der QuelleThe aim of this work is to propose a methodology of fault diagnosis and fault-tolerant control for complex systems. In this work, both sensor and actuator faults are considered. The problem of complex systems instrumentation is studied. In a first step, we design a minimal number sensor network ensuring the system observability. This minimal number network verifies system's observability but it is not robust in the presence of sensor faults: the breakdown of one sensor may lead to the loss of system's observability. We propose then an approach to design a robust sensor network. Finally, we propose a methodology to design a sensor network ensuring the diagnosability of actuator faults in complex systems. These approaches are formulated as nonlinear binary optimization problems. They are illustrated and validated in simulation using a realistic model of vehicle active suspension

Der volle Inhalt der QuelleThe main purpose of our research was to explore the relation between the creative processes and the identity construction. The creative act is personal, subjective an intimate. «Action is to be found at the heart of subjectivity because it has the power of relating aspirations, representations, as well as values and the sense of ability» (Costalat-Founeau, 2008). Our research leans on the theoretical basis of ego-ecology (Zavalloni & Louis-Guérin, 1984; Zavalloni, 2007) which highlights the complexity of the exchanges contributing to the construction of sense and way of being and acting at the very core of identity dynamics. This approach sees the individual on a holistic way; it conceives identity as an internal environment and focuses on the analysis of social representations built as imaged metaphors of reality. The subject as a transactional and dialogical agent is a discursive subject. It's with and in the speech that ego-ecology and the IMIS method try to find a relation between internal and external environment elements by finding identity words that are used as ontological regulators of the identity dynamic and any creative project. The creative project starts and boosts itself in the subject's subjectivity preferring the expression of emotions, values, aspirations, motivations and abilities that take part of a productive power focused on internal and external coherence. We made this exploratory study on a longitudinal way using as subjects fashion design students during three years

Merheb, Abdel-Razzak. „Diagnostic and fault-tolerant control applied to an unmanned aerial vehicle“. Thesis, Aix-Marseille, 2016. http://www.theses.fr/2016AIXM4367/document.
Der volle Inhalt der QuelleUnmanned Aerial Vehicles (UAV) are more and more popular for their civil and military applications. Classical control laws usually show weaknesses in the presence of parameter uncertainties, environmental disturbances, and actuator and sensor faults. Therefore, it is judicious to design a control law capable of stabilizing the UAV not only in the fault-free nominal cases, but also in the presence of disturbances and faults. In this thesis, a new bio-inspired search algorithm called Ecological Systems Algorithm (ESA) suitable for engineering optimization problems is developed. The algorithm is used over the thesis to find optimal gains for the fault tolerant controllers. Sliding Mode Control theory is used to develop two Passive Fault Tolerant Controllers for quadrotor UAVs: Regular and Cascaded SMC. Because Passive Controllers handle a few numbers of faults, an Active Sliding Mode Fault Tolerant Controller using Kalman Filter is developed. To overcome severe faults and failures, an emergency controller based on the Quadrotor-to-Trirotor conversion maneuver is developed. The Controllers developed so far (Passive, Active, and emergency controllers) are then integrated to form the Integrated Fault Tolerant Controller (IFTC). The IFTC is a powerful controller that is able to handle a wide number of faults, and save actuator resources as well as processor computational effort. Finally, Passive and Active Fault Tolerant Controllers are designed for octorotor UAVs based on First Order and Second Order Sliding Mode Control. The AFTC uses Dynamic and Pseudo-Inverse Control Allocation methods to redistribute the control effort among healthy actuators reducing the effect of fault

Der volle Inhalt der QuelleThe work concerns the implementation of an SVM classifier (Support Vector Machine) for an automatic diagnosis of power IGBT module thermal ageing defects, based on thermoelectric measurements. This has required the development of an active cycling test bench for the characterization of the thermal tiredness of IGBT modules, the analysis of the degradations generated in their assembly, and the classification of their operating mode : in " healthy " mode and " degraded " mode. The strategy adopted for the thermal cycling, aims to reproduce the constraints imposed on the components during their real operation. We followed the module static and dynamic parameters in order to detect possible drifts, and thermoelectric parameters used as criteria of thermo-mechanical degradations in their assembly. The thermal stress caused mainly, earlier switching-on and switching-off modes and appearance of a tile-current. A failure analysis has revealed, in the component assembly, bond-wire lift-off, solder layer degradation, and surface dislocation of the gate and emitter metallizations. The implemented SVM classifier, allows to distinguish between an IGBT degraded operating mode and a healthy operating mode, for a preventive maintenance in electric installations where the continuity of service and safety are very important

Der volle Inhalt der QuelleThe miniaturisation of optical trapping systems allows the manipulation and analysis of nano and micron sized objects. These objects can be inert (silica or polystyrene beads, carbon nanotubes) or biological (viruses, bacteria, cells). Integrated trapping devices on chips have the advantage of handling single objects reversibly and at very low power. This makes them very suitable for the study of biological objects, often more fragile and traditionally studied at the population level in microbiology methods. This work deals with the study of different bacteria trapped on 1D and 2D photonic crystals. We first demonstrate the trapping of seven bacterial species: E. coli, B. subtilis, S. epidermidis, Y. ruckeri, N. sicca, P. putida and L. innocua. . We describe a spatial and temporal characterisation methods developed to extract information from this trapping on the size, shape, motility and membrane structure of bacteria. A trapping device with two lasers has also been implemented to allow the fine analysis of the state of an E. coli bacterium subjected to heat stress. These results falls within the issue of bacterial diagnosis, very sensitive in recent years with the increase of the resistance of bacteria to antibiotics. If no change occurs, it is predicted that bacterial infections will be the main cause of death in developed countries by 2050. It is therefore necessary to develop new, faster and more accessible diagnostic tools to limit the large distribution of antibiotics leading to this phenomenon of antibioresistance. We also propose in the last part of this manuscript solutions to integrate our trapping device in order to pave the way for new applications in pathogenic environments

Der volle Inhalt der QuelleThe aim of this thesis is to develop control laws and road bank angle estimation, for the diagnosis of critical situations, this application is known as "Itinerary Rupture DIagnosis", which aims to evaluate the physical limits of a vehicle negotiating a bend, these limits are highlighted when the vehicle operating in the non-linear areas. The exploration to the limit dynamic requires a realistic model of a real vehicle. The first step of this work, is to design linear and non linear control laws, to extrapolate the behaviour of the vehicle model. Several control laws are proposed and validated, some of them control the vehicle via the steering angle, further at the same time control the vehicle via the steering torque and the wheel traction torque. The second step is dedicated for the estimation of the road bank angle using an unknown input sliding mode observer, this in order to make the trajectory more realistic and take into account the effects of this angle on the dynamic behaviour of the vehicle. The third step presents the speed extrapolation tests, starting from a normal driving situation, towards a virtual loss of control, this extrapolation is performed using several instances of a dynamic model run with incremented speeds, these models are controlled by control laws and coupled with road bank angle observer. The last step is devoted to the study and analysis of extrapolated output models, using detection criteria on the limit vehicle dynamics. This phase will allow the detection of dangerous situations and/or save them in the accident road databases. This study provides an important experimental validation phases of the vehicle models, control laws and observer. This validation is performed using experimental data acquired by prototype vehicle Peugeot 307 developed by INRETS-MA, and the bank angle experimental data of the two vehicles VANI and PALAS2. This work led to the design of modules (commands and observer) operating in real time

Der volle Inhalt der QuelleThe main goal of this thesis is to propose diagnostic strategies in the case of a sensorless speed control of a three-phase induction motor under an opened-switch or opened-phase fault. A qualitative analysis of the performances, in terms of stability and robustness, of sensorless control applied to the electrical drive in pre-fault and post-fault operation modes is presented. A model-based sliding mode observer is developed and experimentally validated for sensorless speed control of three-phase induction motor. The signals issued from the observer (model approach) as well as the measured ones (signal approach) are simultaneously used to form a hybrid approach for inverter open-switch fault detection and identification. A second-order sliding mode observer based on Super-Twisting algorithm (STA) is also developed to improve the stability and to ensure the continuity of operation of the electrical drive especially during transient states induced by the fault, permitting thus to apply the reconfiguration step without losing the control

Der volle Inhalt der QuelleThe wind energy capacity carries on growing quickly and taking an increasingly significant place in the world. Progressively, research studies dealing with designing and supervising wind turbines have become more important. Two areas of research were developed in this thesis. The first one concerns the continuity of service of a wind turbine connected to the grid while an inter-turn short-circuit fault is present in the stator phase of the induction squirrel cage generator. The analysis of the fault as well as its impact on the wind turbine system and mainly on the quality of the produced power highlights the interest of development of a fast detection and isolation algorithm, dedicated to the reconfiguration of the control law. Hence, a fault tolerant control scheme has been established in order to avoid stopping production, compensate the fault impact and maintain acceptable performances of the quality of the produced energy. The carried out work was based on sliding mode observers, commonly known as robust tools for monitoring and controlling at the same time. The second axis concerns the structural modeling and stability checking of the wind system under vibratory stresses. The work is divided into two complementary parts: The establishment of a three-dimensional (3-D) numerical model using a finite element analysis software (ANSYS) and the realization of vibratory tests under different excitations within the platform (TREVISE). In this framework, a numerical (3-D) model of a horizontal axis wind turbine coupled to a suitable tower and foundation was developed basing on the finite volume method (FVM) in order to analyze its vibratory behavior. The experimental vibratory tests validate the numerical model and allow the identification of the dynamic response of the structure in a precise way. In addition, we have developed an experimental model of the behavior of the wind turbine under vibratory stresses of random, sinusoidal and impulse shapes

Der volle Inhalt der QuelleThe current gas turbine regulation systems are based on complex architectures that manufacturers tend to make more modular with more cost effective technologies while ensuring a greater or equal level of reliability. In this context, the fuel system health monitoring, which aims to identify critical hydraulic components dysfunction, allows to reduce maintenance costs, to improve maintainability level and to ensure gas turbine availability. The present study focuses on the development of performant and robust diagnosis methods for the detection and isolation of faults affecting primary fuel system hydraulic functions. Existing nonlinear model based residual generation methods are presented and applied to the fuel system. The analytical approach for decoupling, combined with extended Kalman filters, helps fault isolation by generating residual structures. A new approach based on differential flatness theory is proposed for nonlinear systems fault diagnosis with an application to the fuel system. Sliding mode differentiators are used to estimate derived signals that are necessary for the application of some residual generation methods. Numerical simulations illustrate the efficiency of obtained results. An experimental application is presented using a real data set from a partial test bench provided by Turbomeca company of the SAFRAN group

Der volle Inhalt der QuelleMeasurement of the mechanical properties of the membranes surrounding living cells could reveal/reflect their physiological state, pathological condition, or the influence of an external agent such as a drug or virus, or also, the response to stimulation or a therapeutic protocol. The main techniques for measuring these properties have many limitations, particularly in terms of quality, reliability, speed of measurement and number of acquisitions. This thesis focuses on the use of the Circular Mode Atomic Force Microscopy or CM-AFM in liquid media for applications in the field of Health. This mode is obtained by modifying the electronics of an AFM to generate a sliding contact in a circular relative motion. Coupled with the AFM force spectroscopy mode (i.e. the application of a vertical movement to the tip), the MC-AFM allows access, in a single measurement procedure and performed under steady state conditions (continuous displacement at constant speed), to numerous mechanical properties of the biological membrane, some of which are inaccessible by conventional AFM procedures.The main objective of this PhD project is to develop a series of protocols and adapt the MC-AFM to measure the mechanical properties of complex biological objects. Once the protocols have been validated using red blood cells, their interest for applications in the field of Life science is demonstrated by (1) studying the influence of original microalgae-based nutritional protocols on the mechanical properties of red blood cell membranes and (2) for studying the effect of a phytosterol-based treatment on breast cancer cells. These protocols are also useful to better understand the physiological mechanisms involved, and/or the role of the molecules constituting the membrane on the evolution of mechanical properties

Der volle Inhalt der QuelleIn the current era, Smart City projects have to deal with big social, ecological and technological challenges such as digitalization, pollution, democratic aspirations, need to be safe, etc. The higher involvement of multi-stakeholders (such as citizens, users, engineers, researchers, elected representatives, etc.) in the different phases of the projects, is one strategy enabling a variety of perspectives to be considered and thus develop a shared vision of the city. Paradoxically, the dynamic and multiple nature of stakeholders appears to be a source of complications and uncertainty in the decision-making process. Getting a consensus, which means legitimizing a group decision-making process, is often difficult to reach because the different expectations, needs and behaviours. The main hypothesis of the present research is that the consensus process could be facilitated by human and automatic tools through identifying conflicting points and following their evolution after several rounds of discussion. This study will propose a general methodology for two kinds of decision-making process supporting the negotiation between stakeholders within a Living Lab environment, an automatic control system that substitutes the facilitator’s actions and a process supervised by human facilitator. First, a methodology based on a multi-agent system is developed for automatic reaching consensus in large scale group of making decisions without facilitators and direct interaction. Then, a second methodology combining a human facilitator and ICT–based supporting tool. A proposition of multi-criteria and multi-stakeholders methodology supporting consensus reaching processes is used as decision support system tool in Smart City projects under Living Lab environment. Both Living Lab decision-making methodologies, the automatic and the supervised process, were developed, executed and validated in concrete case studies. Throughout using both methods, we can compare how different between the theoretical model and a process of experimenting decision-making tools in the real-life. The results of data analysis from experimentation provide suggestions to improve decision-making process of stakeholders with diverse objective and background in Smart City projects

Der volle Inhalt der QuelleIntroduction: the ability to makes decisions is a crucial skill in emergency medicine. Our study aimed at revealing how and when emergency physicians make decisions during the patients' initial management. Methods : we carried out a qualitative research project based on semistructured interviews with emergency physicians. The interviews concerned management of an emergency situation during routine medical practice. They were associated with viewing the video recording of emergency situations filmed in an “own-point-of-view” perspective. Résults : many results are original. Specifically, we showed the major role played by intuition in the decision making process. Moreover, we revealed the way emergency physicians generate and evaluate diagnostic hypotheses. Conclusions : the use of an innovative research method allowed us to better understand the way emergency physicians make decisions in their everyday practice. Our results are associated with several implications for medical education

Der volle Inhalt der QuelleThe research work done in this PhD has been carried out under an industrial convention (CIFRE) between the IMS laboratory (Bordeaux University, France) and Airbus Operations S.A.S. (Toulouse, France). The thesis deals with two important Electrical Flight Control System failure cases: runaway (a.k.a. hard over) and jamming (or lock-in-place failure) of aircraft control surfaces. Early and robust detection of such failures is an important issue for achieving sustainability goals and for early system reconfiguration. The thesis focuses on the elevator runaway and jamming. Three model-based monitoring strategies are presented. The first approach is based on a dedicated Kalman filtering with optimised tuning parameters. The second method is based on a decision test applied to an identified sensitive direction in the parametric space. Finally, the third solution is based on a sliding mode differentiator. The techniques have been implemented in the flight control computer and validated on Airbus test facilities and during real flight tests. The experimental results confirmed that good level of performance and robustness can be obtained
Rhode, Ann Kristin. „Customizing or conforming ? : exploring cross-cultural differences in consumers' use of brands to signal self-identities and their implications for self-brand connections and product customization“. Thesis, Paris 1, 2018. http://www.theses.fr/2018PA01E079/document.
Der volle Inhalt der QuelleA growing body of research indicates that consumers use branded products as tools to construct their self-identity and to communicate their self-identities to others. Besides acting as markers of status and symbols of group membership, branded products allow consumers to differentiate themselves from others and to express individuality. Key to generating identity related brand meaning and to strengthening self-brand connections, is the involvement of the consumer in a co-creation process. Product design customization on a large scale has emerged as a particularly useful tool to involve consumers in the creation process of the brand and to increase their satisfaction and willingness to pay. However, existing theories on the use of brands to signal self-identities as well as strategies for strengthening self-brand connections, such as product design customization, are bound to Western individualistic thinking. The aim of this research is to investigate the extent to which East Asian consumers differ in their use of brands to signal self identities from Western individualistic consumers. In addition, it explores potential implications of cross-cultural differences in the signaling of self-identities for product design customization and self-brand connections. Following prior studies indicating that clothing and fashion accessories are particularly likely to be used by consumers to communicate self-identities, the focus of the present research is laid on fashion products of both luxury brands and high street brands. In line with the tradition of cultural psychology, this thesis draws on the assumption that cultural variations in self construal and in self-other relationships lead to differences in consumer behavior. A mixed methods approach is taken to investigate cross-cultural differences between samples representing an East Asian collectivistic culture (South Korea) and samples representing a Western individualistic culture (Germany). Specifically, quantitative data collected through surveys (studies1A and 1B) are combined with qualitative data collected through semi-structured in-depth interviews (studies 2A and 2B). This research provides novel, cross-cultural insights relevant to existing the orizing on consumer-brand relationships and on consumers’ use of brands as signals of self-identities. It also contributes to the emerging stream of research on product design

With the advent of knowledge economy, knowledge has been regarded as one of the most important strategic resources. The business competition can be enhanced depending not only on the capital and humane resource, but on the knowledge that can help on creation improvement. Therefore, how to effectively create knowledge and enhance business value is one of the crucial factors to maintain advantageous competition. The research thesis conducts an empirical study that discloses the relationships between knowledge creation mode and knowledge creation performance, as well as the team interactive networking mode and knowledge creation performance. The research thesis also examines the mediating role of knowledge creation process (socialization, externalization, combination, internalization, SECI) on the above mentioned relationships. Research findings indicate that (1) goal-driven creation mode is positively related to the knowledge creation performance; (2) periphery networking mode is positively related to the knowledge creation performance; (3) in the whole process of knowledge creation, the SECI model also posses the mediating effect on the relationship of creation model, networking model and knowledge creation performance.

A B S T R A C T Experience refers to new imagination and memory created from personal experience and feelings. experience given to people from the same artistic space not only is affected by the perceiver’s life experience in the past, but also produces different new perceptions and feelings due to personal practice in time and place. Artistic space without reason; and results of experience will not emerge out of void. The purpose of the study is to present an experiential mode that artistic space brings to people. After literature analysis is made by the study, the characteristics of artistic space is understood, and the connotation of experiential mode is described. Furthermore, “experiential mode” is taken as a research tool so as to understand how artistic space brings people an experiential mode. The experiential mode is divided into 5 kinds: sensory experience, emotional experience, mind experience, action experience and association experience. In a visit of the “Art Bank” Project initiated by the Ministry of Culture, the researcher had interaction with the artist, Chang Hsin-Hung, and was further inspired from the visit and interaction. The inspiration, literature review results, and analytic results of individual cases were added to the researcher’s actual creation (“Compose Settlement”). Art and spatial environment are made to be established on the same platform and have stimulation and response to each other. Through combination of government departments and the private sector, the study has full cooperation with the academic experts, enabling more new design artists to be discovered, and more artistic activities to be supported and promoted. Innovative artistic space is combined with artistic exhibition and performance, making artistic space not being art only, but also letting art creators convey certain message to users through artistic works. More opportunities are explored through interactive teaching, and exchange from attending artistic and cultural exhibitions and performances. As a result, spatial environment is more than an environment. Users’ spirits are getting closer to art. It is discovered that experience is a kind of percipience that varies from person to person. It is a process, and an output. If a perceiver has gone through more experience and accumulated more cognitions, his/her imagination will be richer, and the experience provided by art will be deeper and manifold. An innovative space that combines spatial design with art can increase the active use of space, enhance its artistic value, and people’s aesthetic life experience. More private institutions are urged to combine with innovative artistic space, and provide this kind of artistic space designers with a reference of experiential mode in designing space. Through employment of the 5 kinds of experiential mode, the created artistic space can better meet the needs of users to promote artistic and cultural activities; discover more refined living and cultural connotations; and put social aesthetic spirit into practice.

Abstract This study focused on establishing a set of computerized diagnostic tests of "electromagnetic effect" unit of natural science in elementary school. The test is with both multiple-choice and constructed-response questions.It use the computers to analyze the answer results of the students and combine with a variety of the Bayesian network modes.It can effectively identify the concept of the proposition and the myths of the students to support teachers conducting the remedial instruction. First, analyze the teaching materials of "electromagnetic effect" and establishing the concept of proposition.Then develop the computerized diagnostic test which is based on the concept of the proposition.By using the computers, record the problem-solving process of students in detail to develop the automated analysis model of constructed-response questions.Second,take Bayesian network as a analysis tools to inference the concepts ofproposition and the misconceptions of the students. The results are as follows: 1.In this study, the self examination questions of "electromagnetic effect" of natural field in the sixth grade of elementary school,it's Cronbach's α of multiple-choice questions is 0.756. this study has shown good reliability. 2. compared to multiple-choice questions, the computerized constructed-response questions of "electromagnetic effect" can diagnose a wider variety o the misconceptions of the students. 3.The development of automated analysis of constructed-response questions model in this study, it's average recognition rate for the misconceptions is more than 96%. 4.Comparison of the Bayesian network diagnostic mode results in identifying whether the concept of the myths and propositions or not,the average recognition rate is all more than 97%. 5. Combination of multiple-choice and constructed-response questions of the Bayesian network analysis,whose the recognition rate is superior to the traditional multiple-choice questions of the Bayesian network in the concept of the propositions and the misconceptions.

The goal of the current education system towards the direction of twelve national education students under the pressure in the absence of studies, teachers can quickly understand student learning, so that misconceptions do not affect students' future learning. But the process is often time-consuming diagnostic tests, according to test results for after-school remedial instruction, teachers often troubled by how to perform. Therefore, this study combined with Bayesian network research and development expectations include multiple-choice and constructed response questions of the computer-based diagnostic tests, complete records of student use of computer problem-solving process, by automating scoring model to analyze student responses and answer, which get students more variety of types of errors, in order to improve teachers' scoring burden. According to the results of this study the following conclusions: 1.In this study, the “similar figures” unit, constructed response questions can be computerized diagnostic students a variety error types to help students know their own misconceptions, teachers can help students to master the error type of collective remedial teaching. 2.Developed computer diagnostic system constructed response questions, students were able to automatically detect the error type of the average recognition rate is 0.9218, and the performance is well. 3.Constructed response questions with multiple choice questions after the Bayesian network model 4 is better than only the only choice Bayesian network model 1.
