A Comparative study of Extra-Amniotic Instillation of Ethacridine with Tablet Dinoprostone (PGE2) in Second Trimester Abortion Versus Ethacridine Alone
Authors: Kour Sandeep , Kour G
Published: October 2013

Aims: To study the efficacy of combination of extra-amniotic instillation of ethacridine with tablets Dinoprostone (PGE2) in second trimester abortion as compared to ethacridine alone. Methods: One hundred patients undergoing second trimester abortion were divided into two groups. Fifty patients received extra-amniotic ethacridine lactate 150 ml through Foley’s catheter (Ethacridine group) and the other 50 patients received 150 ml extra-amniotic ethacridine lactate mixed with a 0.5 mg of a crushed tablet of Dinoprostone through Foley’s catheter (Combination group). Both the groups were compared in respect to instillation-abortion interval, completeness of abortion and success rate. Results: The mean age, multiparity parity, and gestational age were comparable in both the groups. The instillation- abortion interval was significantly shorter in combination group as compared to ethacridine group (16.4±7.1 vs. 29.9 ±13.9 hours, p<0.001). Two patients in combination group had instillation abortion interval more than 48 hours as compared to 16 patients in ethacridine group(p<0.0005). Forty one patients (82%) in combination group had complete abortion as compared to 37 (74%) patients in ethacridine group. The success rate was 48/50(96%) in combination group as compared to 45/50 (90%) in ethacridine group. Conclusions: Addition of a 0.5 mg of crushed tablet of Dinoprostone in extra-amniotically instilled ethacridine lactate reduced the instillation-abortion interval significantly, increased the chances of complete abortion and increased the success rate.

Object

The most appropriate method to determine the quality of life of patients with intradural primary spinal tumors (IPSTs) is not still well established.

Methods

Clinical data in 234 patients who underwent surgery for intradural spinal disease were collected prospectively. The 36-Item Short Form Health Survey (SF-36), a generic score scale, was administered to 148 patients with IPSTs to demonstrate if the survey can be used to effectively evaluate these patients. Forty-eight patients were excluded because they did not complete the protocol. The study was finally conducted with 100 patients (45 male and 55 female) with IPSTs, and the results were compared with those of 2 other scales: the McCormick scale and the Aminoff-Logue scale.

Results

Construct validity was demonstrated by confirming the hypothesized relationship between the scores of the SF-36 and the McCormick scale (p = 0.003), the Aminoff-Logue gait subscale (p = 0.025), the Aminoff-Logue micturition subscale (p = 0.013), and the Aminoff-Logue defecation subscale (p = 0.004). Reliability was demonstrated for all 8 SF-36 domain scales and the Physical Component Summary and the Mental Component Summary of the SF-36, where in each the Cronbach alpha satisfied the Nunnally criterion of > 0.85.

Conclusions

The authors' results demonstrated that SF-36 provides valid and reliable data for patients with IPSTs and that the survey can be used appropriately to evaluate these patients.

Authors: Tsutsumida Narumasa , Saizen Izuru , Matsuoka Masayuki , Ishii Reiichiro
Published: October 2013

Ulaanbaatar, the capital of Mongolia, has expanded rapidly over the past decade. Insufficient authority is in place to address this expansion, and many residential plots have been developed in the peripheral regions of the city. The aim of this study is to estimate changes in land cover within the central part of Ulaanbaatar, which has been affected by anthropogenic disturbances. The breaks for additive seasonal and trend (BFAST) method is a powerful tool for implementing this study because it is able to robustly and automatically derive the timing and locations of land cover changes from spatio-temporal datasets. We applied the BFAST method for the first time to urban expansion analysis, with NDVI time series calculated from MODIS (MOD09A1 product) during the period 2000–2010. The results show that land cover has changed across 22.51% of the study area, and that the change occurs at a later time with increasing distance from the city center. Bi-temporal high-resolution satellite images of a sample area in 2000 and 2008 confirmed that the detection of land cover changes by BFAST corresponds to areas in which residential development is dominant. This study demonstrates that BFAST is an effective method for monitoring urban expansion. In addition, it increases the applicability of NDVI time series.

Authors: Jian Sheng-Rui , Chen Guo-Ju , Hsu Wei-Min
Published: October 2013

In this study, the structural and nanomechanical properties of Cu2O thin films are investigated by X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM) and nanoindentation techniques. The Cu2O thin films are deposited on the glass substrates with the various growth temperatures of 150, 250 and 350 °C by using radio frequency magnetron sputtering. The XRD results show that Cu2O thin films are predominant (111)-oriented, indicating a well ordered microstructure. In addition, the hardness and Young’s modulus of Cu2O thin films are measured by using a Berkovich nanoindenter operated with the continuous contact stiffness measurements (CSM) option. Results indicated that the hardness and Young’s modulus of Cu2O thin films decreased as the growth temperature increased from 150 to 350 °C. Furthermore, the relationship between the hardness and films grain size appears to closely follow the Hall-Petch equation.
A Silicon Nanomembrane Detector for Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) of Large Proteins
Authors: Park Jonghoo , Blick Robert
Published: October 2013

We describe a MALDI-TOF ion detector based on freestanding silicon nanomembrane technology. The detector is tested in a commercial MALDI-TOF mass spectrometer with equimolar mixtures of proteins. The operating principle of the nanomembrane detector is based on phonon-assisted field emission from these silicon nanomembranes, in which impinging ion packets excite electrons in the nanomembrane to higher energy states. Thereby the electrons can overcome the vacuum barrier and escape from the surface of the nanomembrane via field emission. Ion detection is demonstrated of apomyoglobin (16,952 Da), aldolase (39,212 Da), bovine serum albumin (66,430 Da), and their equimolar mixtures. In addition to the three intact ions, a large number of fragment ions are also revealed by the silicon nanomembrane detector, which are not observable with conventional detectors.

Amorphous-selenium (a-Se) based photodetectors are promising candidates for imaging devices, due to their high spatial resolution and response speed, as well as extremely high sensitivity enhanced by an internal carrier multiplication. In addition, a-Se is reported to show sensitivity against wide variety of wavelengths, including visible, UV and X-ray, where a-Se based flat-panel X-ray detector was proposed. In order to develop an ultra high-sensitivity photodetector with a wide detectable wavelength range, a photodetector was fabricated using a-Se photoconductor and a nitrogen-doped diamond cold cathode. In the study, a prototype photodetector has been developed, and its response to visible and ultraviolet light are characterized.
Gouvernementalité et participation
Authors: Gourgues Guillaume , Rui Sandrine , Topçu Sezin
Published: October 2013

L’enjeu d’une analyse des critiques de la démocratie participative ne peut aucunement se limiter à une délimitation fictive entre approches distanciées et approches normatives. L’examen de la pluralité et des mutations des postures critiques qui traversent les recherches sur la participation et la délibération publique nous permet de dégager une partition plus significative entre des perspectives surplombantes et celles faisant une place aux évaluations, aux modes d’engagement et aux jugements des acteurs sociaux, généralement sévères à l’égard de l’offre publique de participation. Par-delà la diversité des cadres théoriques mobilisés, se dégage un mouvement général : la critique sociale joue un rôle actif dans toutes réflexions et orientations relatives à la participation, qu’il s’agisse de la production de l’ordre ou au contraire des résistances dont les pratiques participatives font l’objet. Cette consubstantialité des critiques théoriques et sociales invite alors à retenir une approche en termes de « gouvernementalité », afin d’apprécier si, au regard de l’analyse singulière des rapports de pouvoir qu’elle défend, il y a là une posture et une voie analytique propre à renouveler la critique de la participation.
« Où donc est le danger ? »
Authors: Rui Sandrine
Published: October 2013

Peu mobilisée pour penser la sphère publique, la pensée de Foucault fait cependant l’objet d’usages diversifiés. Cet article propose un aperçu de cette diversité qui tient tout autant aux bifurcations et aux contradictions de son œuvre, qu’aux lectures différenciées. Si Foucault est volontiers convoqué pour penser les effets de pouvoir et de police, il l’est moins pour saisir les effets de subjectivation politique, individuels et collectifs. L’article insiste sur tout l’intérêt des travaux qui, sans occulter les premiers, ont su tirer profit d’intuitions heureuses pour penser les seconds au motif que là où il y a pouvoir, il y a résistance.
L'introuvable délibération
Authors: Lefebvre Rémi
Published: October 2013

L’article propose une approche ethnographique d’une conférence de citoyens tenue en novembre 2009 sur les nouveaux indicateurs de richesse, commandée par le Conseil régional du Nord-Pas-de-Calais. Il montre que ce qui se joue dans ce type de dispositifs ne peut s’appréhender au prisme exclusif de la délibération qui fonde pourtant leur légitimité. Ce qui est en jeu dans le jury considéré, c’est moins la délibération que les stratégies de préservation de la « face » des participants, la constitution du groupe et les logiques de sociabilité, les inégalités de participation et les effets de cadrage de l’équipe d’animation.

Nous n’en sommes qu’au début des révolutions introduites dans la guerre par la robotique. Les instruments automatisés sont plus faciles d’usage, plus autonomes, la palette de leurs utilisations s’élargit. Mais ces instruments posent de multiples questions : ils peuvent être « retournés » et soulèvent des problèmes de doctrine et de stratégie. Ils génèrent aussi des problèmes juridiques et interrogent le rapport du système de gouvernement et de la population à l’acte de guerre.
Changement climatique et sécurité agroalimentaire dans le monde arabe

Changement climatique et stress hydro-agricole se combinent dans le monde arabo-musulman aux défis sociaux, économiques et politiques, générant de hauts risques d’instabilité : un constat qui se décline en situations locales diverses. Les analystes « déterministes » pensent qu’un seuil critique est franchi, qui amorce un sombre futur. D’autres, que la décision humaine peut encore inverser les choses ; mais cela exigerait des changements drastiques des États et sociétés de la région.

Le militantisme socialiste n'est plus ce qu'il n'a jamais été
Authors: Lefebvre Rémi
Published: October 2013

Construit par Jacques Ion, le modèle de l’engagement distancié a acquis aujourd’hui la force de l’évidence. Il se diffuse et se légitime de manière circulaire des acteurs vers les observateurs. Véritable prophétie autoréalisatrice, il s’est imposé comme une catégorie du sens commun militant qui valorise au Parti socialiste une conception du militantisme centrée sur l’autonomie individuelle. L’article montre que le modèle occulte les phénomènes de continuité et homogénéise les formes d’investissement militant diverses, hier et aujourd’hui. Il montre aussi que la figure du militant distancié est devenue la représentation légitime de l’engagement au Parti socialiste. On cherche ici à penser conjointement représentations du militantisme et pratiques militantes dans cette organisation.
« C'est du vingt-quatre heures sur vingt-quatre ! »
Authors: Lacroix Isabelle
Published: October 2013

Cet article analyse les mécanismes utilisés par les organisations abertzale (littéralement « patriotes ») au Pays basque français pour produire un engagement de longue durée et intense, malgré les incessantes scissions que connaît ce mouvement depuis sa structuration en 1963. S’appuyant sur un corpus empirique de quarante entretiens biographiques de militants du conglomérat nationaliste réalisés entre 2002 et 2008, d’observations ethnographiques et de sources secondaires, il éclaire les conditions biographiques et les processus institutionnels qui fabriquent un attachement à la cause basque. Tout en mettant en lumière les différents ressorts de l’engagement initial caractéristique de chaque génération, cet article révèle combien la force du maintien de l’engagement militant abertzale dans le temps réside dans la façon dont les institutions militantes entretiennent l’attachement à la cause. Le travail émotionnel et ritualisé autour du prisonnier, la sociabilité festive ainsi que les dispositifs collectifs d’encadrement des engagements individuels renforcent les liens à l’organisation et la cohésion du groupe et rendent difficile le désengagement.
Quand le militantisme s'adapte au terrain
Authors: Massicard Élise
Published: October 2013

Les différences de stratégies et d’actions d’un mouvement transnational sont souvent conçues en termes de ressources ou de structures des opportunités politiques dans chaque contexte national. Cet article défend l’idée selon laquelle les trajectoires contrastées des militants investis dans les espaces en question peuvent également jouer un rôle. Il analyse dans cette perspective les carrières des entrepreneurs du mouvement aléviste en Turquie et en Allemagne. Ayant connu des socialisations politiques et des types de reconversion en partie divergents, ces derniers ont investi dans leur engagement aléviste des compétences différenciées qui peuvent être mises en relation avec les développements contrastés qu’a connus le mouvement. La prise en compte des trajectoires militantes, elles-mêmes liées aux « offres politiques » accessibles selon les contextes et les ressources des acteurs engagés, enrichit les lectures en termes d’opportunités politiques : elle permet de sociologiser l’influence des contextes sur les mouvements, et de réintégrer la sociologie interne des organisations, souvent négligée dans l’étude des mouvements transnationaux.
The Nature of the Cambridge Heterodoxy
Authors: Martins Nuno Ornelas
Published: October 2013

Résumé Dans cet article, je discute de la manière dont le réalisme critique en économie peut contribuer à l’élaboration d’une théorie économique et sociale alternative. Les contributions de la tradition de Cambridge en économie, qui a également influencé le réalisme critique en économie, se révèleront précieuses dans ce contexte. Je ferai valoir que, même si une reprise précoce de l’économie politique classique dans la tradition de Cambridge se concentre sur la reproduction des structures économiques, le réalisme critique en l’économie s’est intéressé, quant à lui, à la reproduction des structures sociales. Ce dernier permet ainsi la reprise d’un cadre qui existait au sein de l’économie politique classique, et qui fut porté à son stade le plus avancé par Marx. Ce cadre est axé sur la reproduction économique d’un surplus, et sur sa distribution (institutionnelle) à travers les différentes classes sociales sous une structure sociale. L’ontologie sociale du réalisme critique nous permet de comprendre pourquoi l’étude de la reproduction d’un système (relationnel) est le meilleur point de départ pour le développement de la théorie économique et sociale.

Published: October 2013

The Internet has permitted some changes that may not have been foreseen on its initial design. We started to constitute friendly or professional interactions, and it eventually enabled the emergence of collaborative actions that resulted in cognitive processes in unusual ways, that is, that take place without the physical presence of those involved but with the effective participation of everyone involved in a broad and democratic approach, constituting a collective intelligence. In the professional world, these interactions can turn into significant gains to developed activities. This chapter reviews relevant findings concerning the cognitive aspects related to the knowledge construction developed under the collaborative work approach in Learning Management Systems (LMS). When working collaboratively in a LMS, the subjects engage in cognitive processes mediated by hypermedia resources that potentially have positive impact on their ability to construct, sense, and/or produce knowledge, to the extent that these resources dynamically dialogue with the already markedly multimodal human cognitive ability. In order to support the analysis, the authors present the relationship between cognitive processes and hypermedia and their influence on knowledge production in an LMS. They also present two experiences developed in Moodle, which showed the possibility of using such resources for people prone to collaboration, resulting in a continuous design optimization of the mentioned course.
A Unified Modelling and Operational Framework for Fault Detection, Identification, and Recovery in Autonomous Spacecrafts
Authors: Bobbio Andrea , Codetta-Raiteri Daniele , Portinale Luigi , Guiotto Andrea , Yushtein Yuri
Published: October 2013

Recent studies have focused on spacecraft autonomy. The traditional approach for FDIR (Fault Detection, Identification, Recovery) consists of the run-time observation of the operational status to detect faults; the initiation of recovery actions uses static pre-compiled tables. This approach is purely reactive, puts the spacecraft into a safe configuration, and transfers control to the ground. ARPHA is an FDIR engine based on probabilistic models. ARPHA integrates a high-level, a low-level, and an inference-oriented formalism (DFT, DBN, JT, respectively). The off-board process of ARPHA consists of the DFT construction by reliability engineers, the automatic transformation into DBN, the manual enrichment of the DBN, and the JT automatic generation. The JT is the on-board model undergoing analysis conditioned by sensor and plan data. The goal is the current and future state evaluation and the choice of the most suitable recovery policies according to their future effects without the assistance of the ground control.
A Feature Selection Approach in the Study of Azorean Proverbs
Authors: Cavique Luís , Mendes Armando B. , Funk Matthias , Santos Jorge M. A.
Published: October 2013

A paremiologic (study of proverbs) case is presented as part of a wider project based on data collected among the Azorean population. Given the considerable distance between the Azores islands, the authors present the hypothesis that there are significant differences in the proverbs from each island, thus permitting the identification of the native island of the interviewee based on his or her knowledge of proverbs. In this chapter, a feature selection algorithm that combines Rough Sets and the Logical Analysis of Data (LAD) is presented. The algorithm named LAID (Logical Analysis of Inconsistent Data) deals with noisy data, and the authors believe that an important link was established between the two different schools with similar approaches. The algorithm was applied to a real world dataset based on data collected using thousands of interviews of Azoreans, involving an initial set of twenty-two thousand Portuguese proverbs.
Decision Criteria for Optimal Location of Wind Farms

Published: October 2013

The objective of the present chapter is to obtain the weights of the criteria that influences a decision problem of vital necessity to the current energy perspectives, which is the optimal localisation of wind farms. The location problem posed presents a hierarchical structure on three levels. The objective or goal to be achieved is in the top level, that is to say the optimal location of wind farms. The second level is constituted by the general criteria that influences the decision and which are the environmental, orographic, location, and climate criteria. These general criteria are then divided into sub-criteria, which constitute the third level of the hierarchy. The information provided by the criteria are of different natures, with qualitative-type criteria coexisting with quantitative-type criteria, and therefore, linguistic labels and numerical values are employed to model, by means of fuzzy triangular numbers, the importance coefficients of the criteria. In order to compare different models for extracting the knowledge, two surveys are prepared based on the Fuzzy AHP methodology, which are submitted to experts in the specific field.
An Integrated Bi-Objective Reverse Logistics Network Design for Remanufacturing
Authors: Shojai Ali Zolghadr , Shahrabi Jamal , Jenabi Masoud
Published: October 2013

Growing environmental and economical concern has led to increasing attention towards management of product return flows. An effective and efficient reverse logistics network enables companies to gain more profit and customer satisfaction. Consequently, the reverse logistics network design problem has become a critical issue. After a brief introduction to the basic concepts of reverse logistics, the authors formulate a new integrated multi-stage, multi-period, multi-product reverse logistics model for a remanufacturing system where the inventory is considered. Two objectives, minimization of the costs and maximization of coverage, are addressed. Since such network design problems belong to a class of NP-hard problems, a multi-objective genetic algorithm and a multi-objective evolutionary strategy algorithm are developed in order to find the set of non-dominated solutions. Finally, the model is tested on test problems with different sizes, and the proposed algorithms are compared based on the number, quality, and distribution of non-dominated solutions that belong to the Pareto front.

Published: October 2013

Over the last decades, the trip-based approach, also known as the four-step model, has been playing an unrivaled role in transportation demand research in Korea. It has been used to predict changes in traffic volume resulting from new transportation policy measures, and also has allowed conducting benefit-cost analyses for new infrastructure provisions. It has been increasingly difficult for the trip-based model to anticipate individual responses to new transportation policy inputs and infrastructure provision as the society becomes personalized and diversified. Activity-Based Modeling (ABM) approaches, predicting travel demand derived from individual activity participations, were introduced to complement the trip-based approach in this regard. The chapter introduces the Seoul ABM project that aims to first apply FEATHERS as an ABM to the data collected in Seoul Metropolitan Area (SMA) and then develop a prototype of the ABM framework for Korea. More specifically, the chapter first briefly describes SMA in comparison with Flanders in Belgium and other countries. It then introduces related research works in Korea and the background of the Seoul ABM project. After these, a FEATHERS framework applied for the Seoul ABM project is described with its data requirements. Major issues of and solutions to the Seoul ABM project are then discussed with regard to the data preprocessing. The chapter ends with a summary and future work.

Authors: Song Xi , Li Jie Yu , Wang Bo
Published: October 2013

In the light of the geometric characteristics of wind turbine and the distribution of stiffeners, the finite element models for the megawatt horizontal axis wind turbine are established by ANSYS. A model analysis is made of the effect of the foundation stiffness, longitudinal stiffeners, ring stiffeners and orthogonal stiffeners on natural frequency and vibration mode of the tower. The results show that the foundation stiffness and stiffeners all have a certain influence on the natural frequency of the tower. There is a 7% difference in the first-order natural frequency between the models of the tower with and without foundation stiffness; there is an increase in natural frequency of the tower when longitudinal stiffeners or orthogonal stiffeners are considered, while natural frequency of the tower experiences an erratic change with the increase of ring stiffeners. The present study will provide some theoretical basis for the optimization design of wind turbines.

Published: October 2013

Heat transfer and fluid flow in the microchannel cooling passages of plane cell type MTPV systems are numerically investigated. The Finite Volume method is adopted for the governing equations discretization; The SIMPLE method is applied to deal with the linkage between pressure and velocities. The microscale effects, such as surface roughness and viscous dissipation are taken into account. Influence of non-uniform heating condition on the flow and heat transfer characteristics of the microchannel cooling passage was discussed. The computer simulations were validated by the experiment data. Numerical results confirm that the effects of non-uniform heating condition on fluid flow and heat transfer in microchannels could not be neglected.

Controlling home appliances through network, as one hot topic in the Internet of Things, can provide a way of convenient remote control of home applications. It will greatly improve the user experience and free users from the tedious and redundant controlling actions. In addition, the potential of home appliances network also reflected in the home security and energy conserving and environment protective. Since remote control and user authentication can effectively help to guarantee the home security and a centralized device control is more effective to reduce energy consumption and waste of resources. "My Private Housekeeper" is a novel network-based appliance control system. In this paper, by taking several popular household appliances as example, we describe the system design and implementation in details.

Authors: Shao Liang , Xiong Lu
Published: October 2013

This paper introduces a multifunctional electric wheel test-bed which focuses on vehicle dynamics (especially for testing the relation between tire force and slip ratio with large cornering force) and durability test of the electric wheel. On the basis of the functional requirements we propose some design specifications, with which mechanical structure and control system design as well as finite element analysis of the test-bed are conducted. The finite element analysis results show that the stress of the whole mechanism especially the critical parts is less than the yield stress limit with enough tolerance, suggesting that the test-bed meets the design specifications.

Nowadays discrete manufacturing enterprises suffer from a bottleneck of capturing and collection of shop-floor production data. Bar code system usually leads to a fact that the production data are inaccurate. In such a situation, radio frequency identification (RFID) technology is introduced into discrete manufacturing enterprises for tracking the real-time production process. In this research, a RFID-based enterprise system architecture is presented. Under this architecture, according to the key issue in RFID application, a data processing model is proposed to manage the RFID raw data and transform them into enterprise level information. Moreover, a multi-rules based data filter is constructed to support the data processing model. And the experimental results show that the filter can effectively process and filter the huge amount of RFID data by using of multi-filtering rules.

Published: October 2013

Lamb waves (LW) are used for damage detection and health monitoring due to the long range propagation ability and sensitivity to structural integrity changes as well as their robustness in different applications. However, due to the dispersive character and multimode nature of LWs, analysis of the acquired ultrasonic signals is very complex. It becomes even more difficult when applied to a complex structure, for instance, an aircraft component with riveted joints and stringers characterized by difficult geometries. Therefore, numerous approaches to the evaluation of damage indices have been proposed in the literature. In this paper, comparison a number of damage indices applied to LWs testing in aircraft aluminum panels. The damage indices, known from the literature have been selected from the application point of view. Artificial neural network has been used for the classification of fatigue cracks and artificial damages induced in the specimens taken from a real aircraft structure. Article presents results of simulation, data analysis and data classification obtained using selected and dedicated neural network. The main aim of the presented research was to develop signal processing and signal classification methods for an aircraft health monitoring system. The article presents a part of the research carried out in the project named SYMOST.
Nonlinear Acoustics in Non-Destructive Testing - From Theory to Experimental Application
Authors: Broda Dariusz , Klepka Andrzej , Staszewski Wieslaw Jerzy , Scarpa Fabrizio
Published: October 2013

A growing interest in non-destructive testing methods based on nonlinear acoustics have been observed for the last ten fifteen years. The majority of methods in this area take their origin from the observation that fatigue damaged materials often behave like mesoscopic nonlinear materials (e.g. rocks) in which nonlinear phenomena have been observed for years. The most important phenomena include: higher harmonics generation, vibro-acoustic wave modulations, amplitude dependent resonance frequency shift and slow dynamic effects. All these phenomena result mainly from elastic wave interactions with contact-type defects. There is enough experimental evidence in the literature showing that these nonlinear effects are much more distinct in damaged materials than in intact ones. Despite the fact that many experimental techniques - based on nonlinear acoustic phenomena - have been developed for the last ten years, the physical mechanism of elastic wave interaction with damage materials still not clear. The main reason is the variety of possible nonlinear mechanisms involved. This includes: nonlinear elasticity and dissipation, contact acoustic nonlinearity based on herztian and rough surfaces contact theories and other effects such us adhesion, friction and thermoelasticity. This paper provides a short summary of various theoretical developments and examples of applications to damage detection in different materials.
The Ideal Final Result and Contradiction Matrix for Machine Condition Monitoring with TRIZ
Authors: Cempel Czesław
Published: October 2013

Condition monitoring of machines (systems) is the science and technology for the assessment of condition of running machine by means of observation of machine phenomenal field, where some symptom of condition can be captured and measured (see for example [Collacott 77]). This means that we are trying to determine the fault space of the machine, its dimensionality and fault advancement, by some observed symptoms of condition, creating in this way our observation space. The fault space of a system (machine) can be assumed by some prior knowledge taken from the experience with the other running machines, and the same concerns with symptom observation space with some redundancy.
Diagnostics and Transversal Vibrations Control of Rotating Beam by Means of Campbell Diagrams
Authors: Zolkiewski Sławomir
Published: October 2013

The paper concerns problem of diagnostics and transversal vibrations control of rotating beamlike system. The considered system is consisted of a simple prismatic beam. The beam is homogeneous and is being rotated round its end. The beam is fixed on the rotational disk. The most common method of analyzing rotational systems is the Campbell diagram. It gives the short and precise information about resonance points and critical angular velocities. In literature it is a very popular method, but used for shaft systems or rotors rather than for beams rotating round the axis of revolution perpendicular to its own axis of symmetry. In this work the exemplary Campbell diagrams for considered systems derived from the dynamic flexibility of beams are presented. In the used mathematical model the Coriolis forces and centrifugal forces were taken into consideration. Also the different types of boundary conditions were applied in this work. The results after proper adaptation can be used in practical applications such as pumps, turbines or wind power plants.
