Management of Operable Primary Breast Cancer in Older Women
Authors: Syed Binafsha M , Parks Ruth M , Cheung Kwok-Leung
Published: September 2014

A considerable number of breast cancer diagnoses are made in older women. Differing physiological needs of older patients and biology of tumors compared with younger patients may alter treatment options between surgery and nonsurgical primary approaches. Adjuvant therapies may benefit these patients; however, concerns about toxicity and physical demands of treatment may affect patient choice regarding treatment. Furthermore, quality of life may be more important to the older individual than curative treatment alone. Growing evidence is emerging for employing Comprehensive Geriatric Assessment to determine other factors that may contribute to treatment decision-making in the older population. The way geriatric oncology is delivered varies, bringing the importance of the multidisciplinary team to the forefront of care delivery in this age group. Future research in this area should include combined consideration of tumor biology and geriatric needs.
Perceptions of Dyspareunia in Postmenopausal Women with Vulvar and Vaginal Atrophy: Findings from the Revive Survey
Authors: Freedman Murray A
Published: September 2014

Symptoms of vulvar and vaginal atrophy (VVA), including dyspareunia and vaginal dryness, have a distinct negative impact on a woman's quality of life. The REVIVE survey highlighted the lack of awareness of VVA symptoms among postmenopausal women with vaginal symptoms, with many women reluctant to initiate discussions with their healthcare professionals despite the presence of vaginal symptoms. The REVIVE survey also provided insights into women's views of VVA treatments. Women reported displeasure with the vaginal administration route, lack of symptom relief with over-the-counter products, and concerns about the safety of estrogen therapies. With the high prevalence of VVA, obstetricians/gynecologists should become vigilant in identifying women with VVA by implementing screening and discussion of symptoms during routine office visits - providing patients with information about appropriate therapies based on the severity and impact of symptoms, keeping in mind individual preferences and perceptions.
Management of Hypertensive Disorders in Pregnancy
Authors: Moussa Hind N , Arian Sara E , Sibai Baha M
Published: September 2014

Hypertensive disorders are the most common medical complication of pregnancy, with an incidence of 5-10%, and a common cause of maternal mortality in the USA. Incidence of pre-eclampsia has increased by 25% in the past two decades. In addition to being among the lethal triad, there are likely up to 100 other women who experience ‘near miss’ significant maternal morbidity that stops short of death for every pre-eclampsia-related mortality. The purpose of this review is to present the new task force statement and novel definitions, as well as management approaches to each of the hypertensive disorders in pregnancy. The increased understanding of the pathophysiology of hypertension in pregnancy, as well as advances in medical therapy to minimize risks of fetal toxicity and teratogenicity, will improve our ability to prevent and treat hypertension in pregnancy. Fetal programming and fetal origins of adult disease theories extrapolate the benefit of such therapy to future generations.
An Exegesis of the IRC §107 Housing Exclusion
Authors: Campbell Linda J. , Jones Lynn Comer , Smith Pamela C.
Published: September 2014

The tax treatment of clergy housing allowances continues to be at the forefront of criticism and debate, on the premise it results in taxpayer inequity. IRC §107 allows clergy to exclude a parsonage allowance from gross income. A historical context and modern-day application of the law, based on clergy (spouse) interviews, is provided. The current legal tenor suggests the housing allowance is unconstitutional because it violates the Establishment Clause. Entanglement (based on the three-prong Lemon Test) is analyzed. The analysis results in a double-edged sword. It appears the exclusion fails the Establishment Clause, but abolishment of the exclusion would create additional taxpayer inequities. We propose both abolishing IRC §107 and amending IRC §119.
Multiple-instance learning with pairwise instance similarity
Authors: Yuan Liming , Liu Jiafeng , Tang Xianglong
Published: September 2014

Multiple-Instance Learning (MIL) has attracted much attention of the machine learning community in recent years and many real-world applications have been successfully formulated as MIL problems. Over the past few years, several Instance Selection-based MIL (ISMIL) algorithms have been presented by using the concept of the embedding space. Although they delivered very promising performance, they often require long computation times for instance selection, leading to a low efficiency of the whole learning process. In this paper, we propose a simple and efficient ISMIL algorithm based on the similarity of pairwise instances within a bag. The basic idea is selecting from every training bag a pair of the most similar instances as instance prototypes and then mapping training bags into the embedding space that is constructed from all the instance prototypes. Thus, the MIL problem can be solved with the standard supervised learning techniques, such as support vector machines. Experiments show that the proposed algorithm is more efficient than its competitors and highly comparable with them in terms of classification accuracy. Moreover, the testing of noise sensitivity demonstrates that our MIL algorithm is very robust to labeling noise
A simultaneous localization and tracking method for a worm tracking system

Published: September 2014

The idea of worm tracking refers to the path analysis of Caenorhabditis elegans nematodes and is an important tool in neurobiology which helps to describe their behavior. Knowledge about nematode behavior can be applied as a model to study the physiological addiction process or other nervous system processes in animals and humans. Tracking is performed by using a special manipulator positioning a microscope with a camera over a dish with an observed individual. In the paper, the accuracy of a nematode’s trajectory reconstruction is investigated. Special attention is paid to analyzing errors that occurred during the microscope displacements. Two sources of errors in the trajectory reconstruction are shown. One is due to the difficulty in accurately measuring the microscope shift, the other is due to a nematode displacement during the microscope movement. A new method that increases path reconstruction accuracy based only on the registered sequence of images is proposed. The method Simultaneously Localizes And Tracks (SLAT) the nematodes, and is robust to the positioning system displacement errors. The proposed method predicts the nematode position by using NonParametric Regression (NPR). In addition, two other methods of the SLAT problem are implemented to evaluate the NPR method. The first consists in ignoring the nematode displacement during microscope movement, and the second is based on a Kalman filter. The results suggest that the SLAT method based on nonparametric regression gives the most promising results and decreases the error of trajectory reconstruction by 25% compared with reconstruction based on data from the positioning system
Forecasting return products in an integrated forward/reverse supply chain utilizing an ANFIS
Authors: Kumar D. Thresh , Soleimani Hamed , Kannan Govindan
Published: September 2014

Interests in Closed-Loop Supply Chain (CLSC) issues are growing day by day within the academia, companies, and customers. Many papers discuss profitability or cost reduction impacts of remanufacturing, but a very important point is almost missing. Indeed, there is no guarantee about the amounts of return products even if we know a lot about demands of first products. This uncertainty is due to reasons such as companies’ capabilities in collecting End-of-Life (EOL) products, customers’ interests in returning (and current incentives), and other independent collectors. The aim of this paper is to deal with the important gap of the uncertainties of return products. Therefore, we discuss the forecasting method of return products which have their own open-loop supply chain. We develop an integrated two-phase methodology to cope with the closed-loop supply chain design and planning problem. In the first phase, an Adaptive Network Based Fuzzy Inference System (ANFIS) is presented to handle the uncertainties of the amounts of return product and to determine the forecasted return rates. In the second phase, and based on the results of the first one, the proposed multi-echelon, multi-product, multi-period, closed-loop supply chain network is optimized. The second-phase optimization is undertaken based on using general exact solvers in order to achieve the global optimum. Finally, the performance of the proposed forecasting method is evaluated in 25 periods using a numerical example, which contains a pattern in the returning of products. The results reveal acceptable performance of the proposed two-phase optimization method. Based on them, such forecasting approaches can be applied to real-case CLSC problems in order to achieve more reliable design and planning of the network
People exposed to traffic noise in european agglomerations from noise maps. A critical review
Authors: Arana Miguel , San Martin Ricardo , Salinas Juan C.
Published: September 2014

Two of the main objectives of the European Directive on environmental noise are, firstly, to unify acoustic indices for assessing environmental noise and, secondly, to standardize assessment methodologies. The ultimate goal is to objectively and comparably manage the impact and evolution of environmental noise caused both by urban agglomerations and by traffic infrastructures (roads, rails and airports). The use of common indices and methodologies (together with five-year plan assessment required by the authorities in charge) should show how noise pollution levels are evolving plus the effectiveness of corrective measures implemented in the action plans. In this paper, available results fromnumerous European agglomerations (with particular emphasis on Spanish agglomerations) are compared and analysed. The impact and its evolution are based on the percentage of people exposed to noise. More specifically, it demonstrates the impact caused by road traffic, which proves to be the main noise source in all agglomerations. In many cases, the results are extremely remarkable. In some case, the results are illogical. For such cases, it can be concluded that either assessment methodologies have been signifi- cantly amended or the input variables to the calculation programs have been remarkably changed. The uncertainty associated with the results is such that, in our opinion, no conclusions can be drawn concerning the effectiveness of remedial measures designed within the action plans after the Directive’s first implementation Phase.
Manual Therapy and Exercise to Improve Outcomes in Patients With Muscle Tension Dysphonia: A Case Series
Authors: Tomlinson Carey A. , Archer Kristin R.
Published: September 2014

Background and Purpose

Muscle tension dysphonia (MTD), a common voice disorder that is not commonly referred for physical therapy intervention, is characterized by excessive muscle recruitment, resulting in incorrect vibratory patterns of vocal folds and an alteration in voice production. This case series was conducted to determine whether physical therapy including manual therapy, exercise, and stress management education would be beneficial to this population by reducing excess muscle tension.

Case Description

Nine patients with MTD completed a minimum of 9 sessions of the intervention. Patient-reported outcomes of pain, function, and quality of life were assessed at baseline and the conclusion of treatment. The outcome measures were the numeric rating scale (NRS), Patient-Specific Functional Scale (PSFS), and Voice Handicap Index (VHI). Cervical and jaw range of motion also were assessed at baseline and postintervention using standard goniometric measurements.

Outcomes

Eight of the patients had no pain after treatment. All 9 of the patients demonstrated an improvement in PSFS score, with 7 patients exceeding a clinically meaningful improvement at the conclusion of the intervention. Three of the patients also had a clinically meaningful change in VHI scores. All 9 of the patients demonstrated improvement in cervical flexion and lateral flexion and jaw opening, whereas 8 patients improved in cervical extension and rotation postintervention.

Discussion

The findings suggest that physical therapists can feasibly implement an intervention to improve outcomes in patients with MTD. However, a randomized clinical trial is needed to confirm the results of this case series and the efficacy of the intervention. A clinical implication is the expansion of physical therapy to include referrals from voice centers for the treatment of MTD.
Coordination and Balance in Children with Birth-Related Brachial Plexus Injury: A Preliminary Study
Authors: Bellows Doria , Bucevska Marija , Verchere Cynthia
Published: September 2014

Purpose: Most children with severe birth-related brachial plexus injury (BRBPI) have some functional impairment, but information on the impact of BRBPI on coordination and balance is limited. The study's purpose was to determine whether children with BRBPI exhibit deficits in body coordination and balance. Method: A prospective cohort study involving 39 children with BRBPI aged 5–15 years was conducted. Range of motion, strength, active movement, and balance and coordination motor skills were assessed using the Bruininks–Oseretsky Test of Motor Proficiency, Second Edition (BOT-2), and the Movement Assessment Battery for Children—Second Edition (MABC-2). A self-report measure of physical disability, the Activities Scale for Kids—Performance Version (ASKp), was also administered. Results: Participants scored a mean of 44.72 on the BOT-2 Body Coordination composite subtest; scores can range from 20 to 80. Eleven participants (28.2%) scored below average on this test. Participants scored a mean of 7.3 on the Balance subtest of the MABC-2; scores can range from 1 to 19. Twenty-six participants (66.7%) scored below average on this test. Of 38 participants, 25 (65.8%) had an ASKp score indicating some level of disability (<95/100); we found a statistically significant difference in balance (p=0.007) between these 25 participants and those without disability (ASKp score 95–100). Conclusions: The majority of our study population scored in the categories of at risk or significant difficulty for balance on the MABC-2. Balance rehabilitation may be a valuable treatment adjunct for children with BRBPI.

Uncalibrated Visual Servo Control of Magnetically Actuated Microrobots in a Fluid Environment
Authors: Piepmeier Jenelle , Firebaugh Samara , Olsen Caitlin
Published: September 2014

Microrobots have a number of potential applications for micromanipulation and assembly, but also offer challenges in power and control. This paper describes an uncalibrated vision-based control system for magnetically actuated microrobots operating untethered at the interface between two immiscible fluids. The microrobots are 20 μm thick and approximately 100–200 μm in lateral dimension. Several different robot shapes are investigated. The robots and fluid are in a 20 × 20 × 15 mm vial placed at the center of four electromagnets. Pulse width modulation of the electromagnet currents is used to control robot speed and direction. Given a desired position, a controller based on recursive least square estimation drives the microrobot to the goal without a priori knowledge of system parameters such as drag coefficients or intrinsic and extrinsic camera parameters. Results are verified experimentally using a variety of microrobot shapes and system configurations.
Identification of Three Elicitins and a Galactan-Based Complex Polysaccharide from a Concentrated Culture Filtrate of Phytophthora infestans Efficient against Pectobacterium atrosepticum

Published: September 2014

The induction of plant immunity by Pathogen Associated Molecular Patterns (PAMPs) constitutes a powerful strategy for crop protection. PAMPs indeed induce general defense responses in plants and thus increase plant resistance to pathogens. Phytophthora infestans culture filtrates (CCFs) are known to induce defense responses and decrease the severity of soft rot due to Pectobacterium atrosepticum in potato tubers. The aim of this study was to identify and characterize the active compounds from P. infestans filtrate. The filtrate was fractionated by gel filtration, and the protection effects against P. atrosepticum and the ability to induce PAL activity were tested for each fraction. The fraction active in protection (F1) also induced PAL activity, as did the whole filtrate. Three elicitins (INF1, INF4 and INF5) were identified in F1b, subfraction of F1, by MALDI-TOF-MS and MS/MS analyses. However, deproteinized F1b still showed biological activity against the bacterium, revealing the presence of an additional active compound. GC-MS analyses of the deproteinized fraction highlighted the presence of a galactan-based complex polysaccharide. These experiments demonstrate that the biological activity of the CCF against P. atrosepticum results from a combined action of three elicitins and a complex polysaccharide, probably through the activation of general defense responses.

Authors: Liu Zilong , Liu Dongsheng , Zou Xuecheng , Lin Hui , Cheng Jian
Published: September 2014

Radio Frequency Identification (RFID) is an important technique for wireless sensor networks and the Internet of Things. Recently, considerable research has been performed in the combination of public key cryptography and RFID. In this paper, an efficient architecture of Elliptic Curve Cryptography (ECC) Processor for RFID tag chip is presented. We adopt a new inversion algorithm which requires fewer registers to store variables than the traditional schemes. A new method for coordinate swapping is proposed, which can reduce the complexity of the controller and shorten the time of iterative calculation effectively. A modified circular shift register architecture is presented in this paper, which is an effective way to reduce the area of register files. Clock gating and asynchronous counter are exploited to reduce the power consumption. The simulation and synthesis results show that the time needed for one elliptic curve scalar point multiplication over GF(2163) is 176.7 K clock cycles and the gate area is 13.8 K with UMC 0.13 μm Complementary Metal Oxide Semiconductor (CMOS) technology. Moreover, the low power and low cost consumption make the Elliptic Curve Cryptography Processor (ECP) a prospective candidate for application in the RFID tag chip.

Published: September 2014

In the new era of connectivity, marked by the explosive number of wireless electronic devices and the need for smart and pervasive applications, Machine-to-Machine (M2M) communications are an emerging technology that enables the seamless device interconnection without the need of human interaction. The use of M2M technology can bring to life a wide range of mHealth applications, with considerable benefits for both patients and healthcare providers. Many technological challenges have to be met, however, to ensure the widespread adoption of mHealth solutions in the future. In this context, we aim to provide a comprehensive survey on M2M systems for mHealth applications from a wireless communication perspective. An end-to-end holistic approach is adopted, focusing on different communication aspects of the M2M architecture. Hence, we first provide a systematic review ofWireless Body Area Networks (WBANs), which constitute the enabling technology at the patient’s side, and then discuss end-to-end solutions that involve the design and implementation of practical mHealth applications. We close the survey by identifying challenges and open research issues, thus paving the way for future research opportunities.

A-t-il existé un syllabaire tyrrhénien ?

Étant admise comme hypothèse de travail l'idée (de Vetter), que la « ponctuation syllabique » étrusque révélerait l'usage plus ancien d'un syllabaire (ici appelé « tyrrhénien »), on s'efforce de préciser les conditions d'une telle hypothèse ; il apparaît qu'en tout état de cause l'innovation supposée (signes diacritiques permettant l'usage quasi alphabétique d'un syllabaire) n'aurait pu se placer qu'en Étrurie même, après 700.

Du conte à la tragédie (À propos d'Antigone, 905-912)
Authors: Germain Gabriel
Published: September 2014

On peut reprendre et préciser, au sujet de ce texte controversé, une piste indiquée au siècle dernier par l'indianisant Pieschel, et reconnaître à sa source un conte apparenté à la tradition des énigmes, des questions embarrassantes ou simplement curieuses. C'est là seulement qu'il a tout son sens. Ce n'est qu'au prix de déformations qu'il est transporté dans la littérature édifiante et l'épopée de l'Inde ou dans la légende de Darius (où le recueille Hérodote) ; il n'est pas mieux à sa place chez Sophocle. Mais le poète n'a fait que partager le goût, plusieurs fois millénaire, que marque encore l'Orient pour ces traits d'ingéniosité.
Histiée de Milet et l'esclave tatoué
Authors: Foucault Jules-Albert de
Published: September 2014

Hérodote rapporte (V, 35) le stratagème imaginé par Histiée, tyran de Milet, retenu à Suse, pour communiquer avec le gouverneur de sa ville, Aristagoras. Il rasa la tête d'un esclave fidèle, y imprima le texte du message à l'aide d'un tatouage et, quand les cheveux eurent suffisamment repoussé, l'expédia à Milet. L'anecdote, peu vraisemblable, est reprise par Énée le Tacticien ( 31,28-29) et, beaucoup plus tard, par Nicéphore Ouranos. Les trois textes imprimés ici parallèlement permettent de juger de leur parenté. On retrouve l'histoire, agrémentée de légères additions, dans les Stratagèmes de Polyen (1,24) et dans Aulu-Gelle (XVII, 9).

Les animaux fabuleux chez Aristote
Authors: Louis Pierre
Published: September 2014

Aristote savant a parfois de nos jours la fâcheuse réputation d'être un esprit crédule, qui fait une large place aux récits merveilleux au lieu de s'attacher à l'étude des faits et à leur explication scientifique. En réalité, un examen objectif de ses traités biologiques révèle que les animaux fabuleux n'occupent qu'une place extrêmement réduite dans ses descriptions : il faut toujours veiller à ne pas considérer comme merveilleux l'animal qui n'est peut-être qu'inexactement décrit, et qui reste difficile à identifier. On s'aperçoit, d'autre part, qu'Aristote fait preuve généralement d'un scepticisme prudent à l'égard des fables qu'il lui arrive de rapporter.

Une nouvelle étude de la danse grecque antique
Authors: Séchan Louis
Published: September 2014

II s'agit de l'ample étude publiée en 1965 par Mme Germaine Prudhommeau sous le titre La danse grecque antique (2 vol.). L'auteur du présent article utilise l'intéressante préface de M. E. Souriau ; mais il insiste sur le fait que le principe de réanimation, où ce dernier reconnaît « une des parties les plus originales de l'ouvrage », se trouve déjà, au moins en germe, dans la théorie des « images en séries ou séries analytiques » de Maurice Emmanuel (à la mémoire de qui, d'ailleurs, le présent livre est dédié). Les notes laissées par M. Emmanuel ont, au surplus, beaucoup aidé à la composition de la partie intitulée par Mme Prudhomneau Les Textes grecs. Un second article analysera par la suite la riche doctrine de cette dernière, dont les connaissances techniques sur la danse et le juste sentiment de son art sont dignes de tout éloge.

Deux expressions de la notion de conscience dans le judaïsme hellénistique et le christianisme naissant
Authors: Pelletier André
Published: September 2014

Συνείδησις et συνειδός sont en concurrence depuis le début de la prose grecque. Mais συνειδός, popularisé par la Comédie Nouvelle, passe chez Philon avec l'imagerie judiciaire, tandis que le substantif συνείδησις, adopté par la littérature sapientiale juive avant Philon, passe, de là, dans les Épîtres du Nouveau Testament et garde une sorte de monopole dans les premiers écrits chrétiens, de la Didachè à Clément d'Alexandrie. Si bien que Méthode d'Olympe, citant de mémoire I Jo III 21, par automatisme substitue συνείδησις à καρδία. C'est avec Origène que συνειδός vient concurrencer συνείδησις dans la littérature chrétienne ; mais l'imagerie judiciaire qui entoure l'expression en trahit l'origine philonienne. Pour une notion aussi importante que celle de conscience, le christianisme des deux premiers siècles avait donc préféré à l'expression la plus courante même dans certains milieux juifs celle qu'avaient choisie les « sages » juifs de l'époque hellénistique.
Grégoire de Nysse et le néo-platonisme de l'École d'Athènes
Authors: Daniélou Jean
Published: September 2014

La pensée de Grégoire de Nysse présente certaines affinités précises avec celle du néo-platonicien Hiéroclès. Mais celui-ci est postérieur d'un demi-siècle. Peut-il y avoir une source commune ? Hiéroclès a connu la pensée d'Ammonios Sakkas, transmise dans la tradition scolaire d'Athènes. Or Grégoire, dont la formation philosophique se rattache à Athènes à travers son frère Basile, a pu être lui aussi en contact avec la tradition d'Ammonios. Ceci éclairerait un point de l'histoire obscure et complexe du néo-platonisme en Orient dans la seconde moitié du IVe siècle.

Published: September 2014

In this study, the cardiovascular system is modeled using an equivalent electronic system focusing on the circle of Willis (COW). COW supports adequate blood supply to the brain. Each cardiovascular artery is modeled using electrical elements such as resistor, capacitor and inductor. MATLAB Simulink software was used to obtain the left and right ventricles pressure as well as pressure distribution at efferent arteries of the COW. Firstly, the normal operation of the system was shown then the stenosis of cerebral arteries was induced in the circuit and the effects were studied. In the normal condition, the difference between pressure distribution of right and left efferent arteries (left and right anterior cerebral arteries (ACA-A2), left and right middle cerebral arteries (MCA), left and right posterior cerebral arteries (PCA-P2) was calculated to see the effect of anatomical difference between left and right sides of supplying arteries of COW. In stenosis cases, the effect of internal carotid artery (ICA) occlusion on efferent arteries pressure was investigated. The model results were verified by comparing to the clinical observation reported in the literature.
Application of Event Ontology Construction Method in the Field of Mine Safety
Authors: Shen Qi , Wang Yu
Published: September 2014

The concept of ontology stems from philosophy to systematically explain and illustrate the objective existence. This interpretation does not depend on any particular language and concerns abstract nature of objective reality. Because of this characteristic of ontology, ontology has been widely used as a way of knowledge representation. Traditional ontology is defined as the relationship between them, which is appropriate to represent the static concept. But humans understand the real world taking event as a unit. In order to more accurately describe the objective world, this paper proposes a method for constructing event ontology model and applied this method to the field of mine safety, establish event ontology in the field of mine safety , which is important for knowledge representation and semantic retrieval on mine safety event .
Current-Fed Flyback Push-Pull DC-DC Converter Based on Three-Phase Transformer
Authors: Yuan You Chen , Zhang Yang , Chen Yu Wei
Published: September 2014

Three-phase current-fed flyback push-pull dc-dc converter is proposed in this paper, which is a new circuit topology putting into practice based on current-fed flyback push-pull dc-dc converter. Structure is simplified; cost is cut down; efficiency and reliability are improved all by the high frequency three-phase transformer technique that carries out functions of flyback transformer as well as push-pull transformer at the same time. Three-phase transformer can be separated into relatively independent functions of flyback transformer and push-pull transformer with the reluctance produced by the magnetic gap in the central phase; the flyback transformer produces only common-mode flux in the magnetic circuit of push-pull transformer and does not influence its output signal; the magnetic flux in push-pull transformer is blocked by the magnetic gap and can only flow through the outer magnetic loop. Investigational device is designed; static and dynamic characteristics are observed and test results are verified by the experimentation.

The Development of Automatic Tracking Filter for Data Acquisition in Fault Diagnosis System Based on FPGA
Authors: Gu Yong Bin , Jiang Zhi Nong , Luo Qi
Published: September 2014

The running speed of rotating machinery will have a negative influence on the quality of acquired data used in fault diagnosis. Poor-quality signal may cause misinterpretation of monitoring system, and even lead to the false alarms or failure of detection. To improve the quality of the signal and enhance the accuracy of the fault monitoring system, a novel automatic tracking filter for data acquisition based on FPGA was developed. This newly developed filter can adjust to its real-time cut-off frequency relying on the detected rotational speed. Moreover, the introduction of the Ping-Pong operation realized the non-disturbance shifting of output data.

Classic information theory is based on the probability information which isn't involved in any fuzzy events. A hypothesis of transformation and classification of uncertain information sources presented in this paper is exploited to explain several phenomena in information retrieval. First, the form of uncertainty is introduced including fuzzy and random. Then an information source containing a sample space and a fuzzy set is supposed to illustrate the hypothesis based on which a method of identification for information sources is educed. And there are also some problems for further study, such as the transformation mechanism between different information sources and so on.

Published: September 2014

Evaluation methods for the spatial distribution uniformity of a large number of particles have important applications in a range of scientific and industrial problems. We report a quantitative image-processing method to evaluate the spatial distribution uniformity of particles using the Voronoi tessellation and Delaunay triangulation. Given the geometric particle centroids, we constructed the Voronoi tessellation and Delaunay triangulation. For each of the Voronoi cell, the volume, facet area, and number of neighbors (facets) were calculated. For the Delaunay simplices, the volume and the distance between neighbors were calculated and the distributive characteristics were compared between different particle patterns. Simulation results demonstrated that distributions of the above metrics were numerically related to the uniformity of the particle spatial displacement. More studies are needed to further validate the results and refine the method.

Published: September 2014

In order to make better use of video image processing technology to monitor and analyze behaviors of animals, a new walking posture analysis method based on star skeleton is proposed. Firstly, a pig target is detected and its boundary is extracted from the images. Secondly, according to the target’s boundary the center of mass is computed and the curve of distance between contour points and center of mass is draw. The extremums of the above curve are computed to obtain the key contour points from the curve. The stick model of pigs is built by connecting the key contour points with its center of mass. Finally, the gaits of pigs are recognized by analyzing cyclic motion of the key contour points in the stick model. More specifically, the foreleg walking frequency of pigs could be calculated using the spectrum analysis method. The experiments results indicate that this method has higher recognition accuracy for the walking gaits of pigs. The relative error of the results is only within 10%. Furthermore, compared with manual monitoring method, it is more objective and convenient. Thus, this algorithm provides a new solution for animal behavior analysis based on video surveillance and image processing.

It includes the online database concerning process safety knowledge, production-related information system which can be used to train operators and fulfill online inquiry. It also contains hazard fingerprints libraries and the hazard countermeasure libraries of chemical process. PSMS can executive computations with different scales and types based on massive real-time data collected from process. And the computation results can be matched with the hazard fingerprints database to evaluate and predict the process safety situation. If PSMS interacts with the DCS, the process may eliminate hazard by itself based on the hazard countermeasure database. Therefore, the real time information and safety knowledge of process can be organized to form wisdom, which would enhance the process safety greatly.

Published: September 2014

This paper investigated the problem of transmit power minimization to meet the users’ outage probability constraints in downlink smart antennas-MIMO (SA-MIMO) systems. Firstly, a downlink multi-user SA-MIMO system model is established, and the transmit power optimization problem is formulated. The optimization problem jointly optimizes the beam-forming vectors and user outage probability. Then, the outage-based optimization problem is transformed into a geometric programming problem in which the beam forming vectors were obtained by maximum diagonal element (MDE) rule. Some numerical results show that the proposed method in this paper is viable and the transmit power in downlink SA-MIMO systems significantly descreases relative to traditional MIMO systems.
