Classification of flexible manufacturing systems

There has been some uncertainty concerning the conditions under which a manufacturing system may be termed 'flexible'. To clarify this confusion eight types of flexibilities are defined and described. A FLEXIBLE Manufacturing System (FMS) is an integrated, computer-controlled complex of automated material handling devices and numerically controlled (NC) machine tools that can simultaneously process medium-sized volumes of a variety of part types. tsl This new production technology has been designed to attain the efficiency of well-balanced, machine-paced transfer lines, while utilizing the flexibility that job shops have to simultaneously machine multiple part types. Recently, many new manufacturing facilities have been labelled FMS. This has caused some confusion about what constitutes an FMS. Flexibility and automation are the key conceptual requirements. However, it is the extent of automation and the diversity of the parts that are important; some systems are termed FMS just because they contain automated material handling. For example, dedicated, fixed, transfer lines or systems containing only automated storage and retrieval are not FMSs. Other systems only contain several (unintegrated) NC or CNC machines. Still other systems use a computer to control the machines, but often require long setups or have no automated parts transfer. Some systems are called flexible because they produce a variety of parts (of very similar type, using fixed automation). In most of these examples, the operating mode is either transfer line-like or based on producing batches of si mi lar part types. To help clarify the situation, eight types of flexibilities will be defined and described. Examples or explanations are provided when needed to illustrate a particular flexibility type. Measurement and attainability of each are also discussed. q Machine Flexibility: the ease of making the changes required to produce a given set of part types. Measurement of these changes include, for example, the time to replace worn-out or broken cutting tools, the time to change tools in a tool magazine to produce a different subset of the given part types, and the time to assemble or mount the new fixtures required. The setup time required for a machine tool to switch from one part type to another includes: cutting tool preparation time; part positioning and releasing time; and NC program changeover time. This flexibility can be attained by: (a) technological progress, such as sophisticated tool-loading and part-loading devices; (b) Proper operation assignment, so that there is no need to change the cutting tools that …
Perceived Needs of Decided and Undecided Two-Year Community College Students.

The purpose of this study, using a needs assessment methodology, is to determine if, ant' to what extent, students who are undecided on a program of study differ from those pursuing a program of study leading to graduation. A stratified, random sample of 400 students enrolled at the Community College of Rhode Island was selected to receive a 54-item questionnaire which examined academic, personal, and social needs; specific events which influenced college attendance; and specific reasons for pursuing an education. The data analysis is based on 243 returned queStionnairos, or 61% of the population surveyed. The results of this study suggest a good deal of similarity between decided and undecided students. Yet, the data also indicate that undecided students are older students, particularly female, returning as funds become available and as child rearir responsibilities lessens and who have specific needs f,. freer and personal counseling which require attention beyo-aditional services. Further research with the undecided population is suggested.
Speed and Current Controllers Design of BLDC Motor Using SNR Optimization Technique

In this paper, a novel tuning technique for the current and speed controllers of the Brushless DC (BLDC) motor derive system is presented. The parameters of PI controllers in the inner current control loop and outer speed control loop which vary with the operating conditions such as variation of temperature and saturation phenomena or load torque changing of the drive are adjusted in order to maintain deadbeat response for speed and current of motor. A Signal-toNoise Ratio (SNR) optimization technique is employed in this study to obtain optimal parameters of PI controllers. Results of the proposed technique are compared with the response of Particle Swarm Optimization (PSO) technique. Simulation results show that the proposed optimized PI controllers improves significantly the dynamical performances of the motor derive system such as settling time and overshoot against parametric uncertainties. Also, it is superior to the designed controller using PSO method one.
Mindfulness As a Meta-Predictor of Personal and Professional Competence of a Labor Subject

Background: The article deals with psychological factors affecting professional development of a labor subject under the conditions of socio-economic shocks, information overloads and modernization of virtually all areas of professional activities. The research looks at psychological predictors of an individual’s constructiveprofessional development, as well as conditions for building coping skills in such critical situations as stress, conflict, frustration, etc., which are the causes of emotional burnout, professional destruction, deviant behavior, deterioration of occupational and psychological health, psychosomatic disorders, and so on. The analyzed phenomenon is a labor subject’s ”psychological immunity” to professional destruction stemmingfrom multiple increase in intensity of negative impact on individual psycho-emotional state. The research defines the role of psychological immunity in constructive professional development and personal and professional competence. Design: Academic novelty of the article consists in analysis of the psychological construct of mindfulness, which is new to Russian science. The author views this construct as a psychological meta-predictor of personal and professional competence belonging to the structure of personal and cognitive features of individuals and ensuring effective unleashing of their personal potential. Results: The research has found out the link between the psychological predictors of constructive professional development and the mindfulness level of an individual, which makes it possible to broaden the understanding of individual psychological characteristics and capabilities of labor subjects in their topmost achievements, to define strategies for effective use of psychological and intellectual resources of a professional, for choice betweendestructive and constructive professional development in favor of the latter and for shaping personal and professional competence. Conclusions: On the meta-cognitive level mindfulness contributes to building a labor subject’s psychological immunity for overcoming professional destruction, determines acquisition of personal and professional competences required for constructive professional development and an increase of personal and professional competence. Keywords: Mindfulness, psychological predictors, meta-concept, personal and professional competence.
Abstract IA20: A telomere-dependent DNA damage checkpoint induced by prolonged mitotic arrest

Telomere shortening and disruption of telomeric components are pathways that induce telomere deprotection. Here we describe another pathway, where prolonged mitotic arrest induces damage signals at telomeres in human cells. Exposure to microtubule drugs, kinesin inhibitors, proteasome inhibitors or the disruption of proper chromosome cohesion resulted in the formation of damage-foci at telomeres. Induction of mitotic telomere deprotection coincided with dissociation of TRF2 (Telomere Repeat binding Factor 2) from telomeres, telomeric 3′-overhang degradation and ATM (Ataxia Telangiectasia Mutated) activation, and could be suppressed by TRF2 overexpression or inhibition of Aurora B kinase. Normal cells that escape from prolonged mitotic arrest halted in the following G1 phase, whereas cells lacking p53 continued to cycle and became aneuploid. We propose a telomere dependent mitotic duration monitoring system that reacts to improper progression through mitosis and will discuss the molecular details and implications of this pathway.

A letter soup for the quality of information in sensor networks

In this paper, an information grouping paradigm for QoI in sensor networks is introduced. First, a definition of QoI is presented by analyzing the ITU's definition of QoS. Then, the concept of operational context to facilitate the dynamic binding of sensor resources to applications is presented and the 5WH principle ({why, when, where, what, who, how{) for summarizing the information needs of an application and the capabilities of the sensing resources is introduced. Finally, a brief treatise on metrics composition for relevancy parameters is presented.
Taphonomy and palaeoecology of Late Triassic (Carnian) ammonoid concentrations from the Taurus Mountains, Turkey

The deposits of the Carnian Kasımlar Formation within the Taurus Platform Units of south‐western Turkey represent an important archive of a Late Triassic ecosystem. New palaeontological information was obtained by analysing the Kasimlarceltites mass occurrence, located within the Kasımlar Formation and named after the Lower Carnian (Julian) ammonoid genus Kasimlarceltites. This is the dominant taxon (> 94%) within the mass occurrence: nearly 775 million ammonoids and 50 million gastropods were extrapolated for the whole extension (at least 5 km2) of the Kasimlarceltites beds. This calculation is one of the main findings within this study, as it is the first time that such a fossil mass occurrence was quantified. Additionally, orientation measurements of the planispiral ammonoids and the helical gastropods enabled reconstructing the history of the mass occurrence and interpreting the underlying transport mechanisms. Further taphonomic aspects (e.g. biofabric, preservation, bioerosion or genetic classification) as well as comparisons with samples of the same acme zone from different localities near Aşağiyaylabel (AS IV, KA I‐II) point to a two‐phased genetic history. Accordingly, local mass mortality within the Kasimlarceltites fauna due to oxygen fluctuations or methane degassing may have initially led to a primary accumulation. These deposits were then reworked and redeposited basinward by gravity flows to create the present‐day secondary allochthonous concentrations.
A Turkish Translation, Validity and Reliability Study of the Dimensions of the Learning Organization Questionnaire

2 Abstract: This paper discusses the methodology and findings on the validity and reliability of the translation of Dimensions of the Learning Organization Questionnaire (DLOQ) into Turkish. The translation method was a five-step model including forward translation, assessment of forward translation, backward translation, assessment of backward translation and local meeting with professionals. To test the construct validity of translated instrument, a factor analysis was performed and to examine the reliability of the measure Cronbach's alpha coefficients were calculated. The results showed that the Turkish version of DLOQ was a valid instrument to measure the learning processes in organizations in Turkey. Thus, with the help of this study a cross-cultural validation of DLOQ has been done. The findings might inspire some new researches in different cultures other than western ones.
The Enigmatic Radio Afterglow of GRB 991216

We present broadband radio observations spanning 1.4-350 GHz of the afterglow of GRB 991216, taken 1-80 days after the burst. The optical and X-ray afterglow of this burst were fairly typical and are explained by a jet fireball. In contrast, the radio afterglow is unusual in two respects: (1) the radio light curve does not show the usual rise to maximum flux on timescales of weeks and instead appears to be declining already on day 1; and (2) the power-law indices show significant steepening from the radio through the X-ray bands. We show that the standard fireball model, in which the afterglow is from a forward shock, is unable to account for point 1, and we conclude that the bulk of the radio emission must arise from a different source. We consider two models, neither of which can be ruled out with the existing data. In the first (conventional) model, the early radio emission is attributed to emission from the reverse shock, as in the case of GRB 990123. In the second "dual fireball" model, the radio emission originates from the forward shock of an isotropically energetic fireball (1054 ergs) expanding into a tenuous medium (10-4 cm-3), while the optical and X-ray emission originate in a jetlike outflow. Finally, we note that the near-IR bump of the afterglow is similar to that seen in GRB 971214, and no fireball model can explain this bump.
Cohort profile: The Mauritius Child Health Project.

Psychiatry 2 met in 1967 to assess whether neurophysiological methods could be applied to further highrisk studies. The WHO Group outlined the advantages of examining high-risk individuals early in childhood prior to the onset of clinical disorders, and recommended early experimental interventions to alter neurophysiological risk factors for psychopathology. The importance of malnutrition as well as poverty as stressors was highlighted, together with the potential benefits of enhancing educational and health services in a developing country. The recommendations of the Scientific Group’s 1968 report that formed the basis for the Mauritius study were: (i) conduct the study in a developing country; (ii) investigate 3-year-old children; (iii) establish nursery schools as settings for the study; and (iv) use psychophysiological methods to identify children at risk. The initial aim of the study, which would distinguish it from other high-risk studies, was to investigate the possibility of primary prevention of psychopathology by random assignment of 100 children to an environmental enrichment set up in nursery schools, involving better nutrition, more physical exercise and cognitive stimulation. 3 P.V. has been the Principal Investigator (PI) of the project from 1972 to 1987, whereas A.R. has been PI from 1987 to the present date.
Data Driven Modelling of the Dynamic Wake between Two Wind Turbines

Abstract Wind turbines in a wind farm, influence each other through the wind flow. Downwind turbines are in the wake of upwind turbines and the wind speed experienced at downwind turbines is hence a function of the wind speeds at upwind turbines but also the momentum extracted from the wind by the upwind turbine. This paper establishes flow models relating the wind speeds at turbines in a farm. So far, research in this area has been mainly based on first principles static models and the data driven modelling done has not included the loading of the upwind turbine and its impact on the wind speed downwind. This paper is the first where modern commercial mega watt turbines are used for data driven modelling including the upwind turbine loading by changing power reference. Obtaining the necessary data is difficult and data is therefore limited. A simple dynamic extension to the Jensen wake model is tested without much success. The best model turns out to be non linear with upwind turbine loading and wind speed as inputs. Using a transformation of these inputs it is possible to obtain a linear model and use well proven system identification methods. Finally it is shown that including the upwind wind direction to explain the wake improve the prediction performance.
Revisiting Two Classical Results on Graph Spectra

Let mu(G) and mu_min(G) be the largest and smallest eigenvalues of the adjacency matricx of a graph G. We refine quantitatively the following two results on graph spectra. (i) if H is a proper subgraph of a connected graph G, then mu(G)>mu(H). (ii) if G is a connected nonbipartite graph, then mu(G)>-mu_min(G).
Genetic Algorithms and Cellular Automata : unraveling the Bitmap Problem

Using Genetic Algorithms to evolve Cellular Automata rules to solve a given problem is a well-known method. The Bitmap Problem however, with it’s versatile and challenging characteristics, remains quite unknown. This thesis focuses on the Bitmap Problem and tries to expose its inner workings, possibilities and pitfalls. Multiple aspects of the Bitmap Problem like grid size, state set and updating method are being adjusted to measure their influence. In the final chapter of this thesis an algorithm is described which uses the Bitmap Problem as key ingredient for a data compression algorithm.
Predictive Maturity of Computer Models Using Functional and Multivariate Output

Computer simulations are valued in science and engineering because they enable us to gain knowledge about phenomena that would otherwise be difficult to understand. Dependency on simulations primarily stems from our inability to conduct a sufficient number of experiments within the desired settings or with sufficient detail. However, if one were able to conduct a large-enough number of experiments, it is reasonable to envision that a simulation model could be calibrated to the point that its predictive uncertainty is reduced down to uncontrolled, natural variability. We inductively conclude that, as new experimental information is used for calibration, the calibrated parameters should stabilize, and thus, the disagreement between simulations and experiments should be reduced down to "true" bias. We propose to use the stabilization of the incremental improvement to assess the predictive maturity of a model. Accordingly, we develop a Prediction Convergence Index (PCI) that approximates the convergence of predictions to their "true" or stabilized values or, conversely, can be used to estimate the number of experimental tests that would be required to reach stabilization of predictions. The application of the PCI is illustrated using a Preston-Tonks-Wallace material model for Tantalum and six experimental datasets in the form of strain and stress curves. Once the predictive maturity of a model has been assessed, we argue that it is acceptable to extrapolate its predictions away from settings or regimes where validation tests have been conducted as long as the physics involved and modeled by the code remains unchanged. For the given model, the extent to which extrapolation and interpolation are acceptable is investigated. The results agree with our hypothesis and suggest that the approach proposed can prove useful for claiming completion of the calibration phase and providing insight into the predictive maturity of numerical models.
Partnership and collaboration in sport: a study in the context of the New Opportunities for PE and Sport programme in three English cities

Tett et al. (2003, p38) state that ‘themes of collaboration and partnership … are at the centre of New Labour’s vision of a modernised welfare state’. Concomitant with this government focus, the quantity of research on partnership and collaboration has expanded rapidly. However, there have been few studies of these types of relationships in the field of PE, school and community sport. In order to begin to address this gap, this study examined partnership and collaboration in the context of the New Opportunities of PE and Sport (NOPES) programme. The study was underpinned by a variety of theoretical concepts included those, such as policy networks, that may be specifically related to partnerships and collaboration as well as others, such as governmentality, that are more generic. Within three case studies of specific local authority areas, interview data from stakeholders in the NOPES programme was combined with documentary evidence where available. Cross-case analysis identified a variety of complex forms of partnership and collaboration both within the NOPES programme itself and its wider context. These different partnerships and collaborations all had an effect on the NOPES policy process in the respective case studies but in varied ways according to their different forms and the agencies involved. As a result of these findings, a number of implications for future policy related to partnership and collaboration were identified. In particular, it was suggested that a more nuanced policy approach based on an understanding of the complexities of partnerships and collaboration should be adopted. The findings also stimulated suggestions for theoretical development, especially of the policy networks concept, and for future research both in the context of sport and other policy areas.
Routing protocol based on sleep scheduling and tree cluster structure in wireless sensor network

Sensor nodes have limited energy supplied and non rechargeable battery. Each sensor node consumed energy in sensing, data processing and communication. In order to prolong lifespan of the sensor nodes, only the data transmission has been assigned to sensor nodes. A variety of approaches has been developed to save the energy consumption. In our approach, we have designed a protocol by turning off radio (sleep mode) of sensor nodes which are transmitting almost same information. The less energy will be consumed in the present technique which enhances the lifetime of the network due to the removal of data redundancy. The use of tree cluster structure further reduces the energy consumption by constructing a tree in which cluster-head is taken as root. The simulation indicates that this protocol has better results in comparison to earlier protocols like LEACH and PEGASIS.
Maternal Plasma Procalcitonin Concentrations in Pregnancy Complicated by Preterm Premature Rupture of Membranes

Objectives. Our objective is to compare maternal plasma procalcitonin concentrations in preterm premature rupture of membranes (pPROM) and premature rupture of membranes (PROM) at term with their levels in uncomplicated pregnancy, and to determine whether these concentrations are useful in the diagnosis of pPROM cases suspected of infection and in the prediction of pPROM-to-delivery interval. Study design. Forty eight patients with pPROM, 30 with PROM at term, 31 healthy women at preterm gestation, and 33 healthy women at term were included. In pPROM group, analysis of procalcitonin concentrations with reference to leucocytosis, serum C-reactive protein, vaginal fluid culture, neonatal infection, histological chorioamnionitis and pPROM-to-delivery interval was carried out. Results. Procalcitonin concentrations in pPROM and PROM at term cases were comparable. However, in both groups procalcitonin values were significantly higher than in healthy controls in approximate gestational age. In pPROM group, procalcitonin concentrations between the patients with and without laboratory indices of infection were comparable, as well as between patients who gave birth to newborns with and without congenital infection, and between patients with and without histological chorioamnionitis. The predictive values of procalcitonin determinations were poor. Conclusion. The value of maternal plasma procalcitonin determinations in the diagnostics of pPROM cases suspected of intraamniotic infection, as well as for the prediction of pPROM-to-delivery interval, newborn's infection or histological chorioamnionitis is unsatisfactory. However, procalcitonin concentrations are elevated, both in patients with preterm and term PROMs in comparison to healthy pregnants, and therefore further evaluations are necessary to establish the role of procalcitonin in the pathophysiology of pregnancy.
