Measurement of complexity in manufacturing systems: a systematic literature review and a conceptual framework

This paper provides a comprehensive review of the scientific works that define a method for measuring or a measure of complexity in manufacturing systems. We analyse a total of 39 peer-reviewed journal articles by reference, methodology, theoretical background, type of complexity, unit of analysis and main topic (i.e. product, process, resources and overall system). We then provide a conceptual framework that identify six classes of measures by object of the measure (i.e. structure or behaviour of the measured system) and process of application of the measurement.
One Platform, a Thousand Worlds: On Twitter Irony in the Early Response to the COVID-19 Pandemic in Italy

On 22 February 2020, 11 municipalities in Northern Italy became the first COVID-19 red zone of Europe. Two days later, when it became evident that the virus had been spreading in the country for weeks, Italy entered a “buffer zone,” a temporal zone between normality and pandemic. The buffer zone lasted around 2 weeks and thrived with irony flowing on social media through memes, multimedia remixes, and jokes. As a collective ritual, irony allowed people to temporarily background the mounting feelings of bewilderment and uncertainty by foregrounding the familiar scripts of playful and grassroots expressivity typical of networked publics. While giving the country a way to breathe before grieving, irony delivered both traditional political satire and new symbolic arrangements to frame “us” versus “them”: Northern Italy versus Southern Italy, Italy versus China. We advance initial reflections on irony and its functions during what we call Italy’s COVID-19 buffer zone and argue for the need of more platform research interested in how users appropriate devices and vernaculars in ways that are culturally bound. In other words, can we rethink “The Platform” (e.g., Twitter, Facebook, Instagram) as a constellation of small-world-platforms—sometimes overlapping, other times segregating—each shaped by local hopes and fears, histories and events?
A REVIEW: THE PHYSICOCHEMICAL CHARACTERISTICS OF INDOOR PARTICULATE MATTERS IN RELATION TO HUMAN HEALTH

Particulate matters exposure significantly affects human health, especially for those who are working indoor such as in a workplace, house, office, laboratory and vehicle. The objective of this paper is to review the existing physicochemical characteristics of particulate matters from their various sources, to investigate the differences and similarities and the effect of emission sources. Which largely influences the size, the shape, and chemical compound? The result shows that the physicochemical characteristics may exacerbate human health.
Electronic Limit Order Books, Dealer/Specialists, and Inter-Market Competition on NASDAQ

This study analyzes execution costs and competition for order flow between the NASDAQ Stock Market and five other trading venues that trade NASDAQ-100 securities (QQQ). We find that NASDAQ controls the most market share, although it has both the inside bid and ask only 50.24% of the time. These shares are much smaller than similar proportions reported for the NYSE, indicating a greater level of quote and order flow competition on NASDAQ. In addition, the dealer/specialist trading venues (NASDAQ, AMEX, and the Chicago Stock Exchange) show a decreasing percentage of trades from large to small trades, while trades through electronic limit order book systems (Archipelago and Island) exhibit an increasing percentage of trading from large to small trades. We find that both effective and realized spreads are smallest for the electronic limit order book systems and larger for the dealer/specialist systems. We also find evidence that order flow fragmentation and competition has hurt the markets as the NBBO spreads appear crossed 2.24% of the time and locked 12.43% of the time. Using a multinomial logistic regression, we find that all non-NASDAQ market centers have a lower likelihood of executing a trade as compared to NASDAQ itself, although the likelihood increases if the quotes are more competitive. Our findings suggest that extant findings on inter-market competition for NYSE-listed securities are not a result of the NYSE being the primary market, but instead due to differences in market structure.
A Different Perspective on Critically Stressed Fractures and Their Impact on Fluid Flow*

Naturally fractured reservoirs are often characterized by high-density multi-scale fracture networks, organized in multiple orientation families. However, not all fractures contribute to fluid flow under in-situ stress conditions. The Coulomb friction criterion has long been applied to predict the probability of reactivating faults and fractures in the subsurface, and hence quantify which part of the fracture network contributes to flow at in-situ stress conditions (Barton et al., 1995; Rogers, 2003).
An Infovis approach to compare ATC comets Comparing visual entities with a theoretical foundation

(cid:178) Air Traffic Control systems display information with multiple visual entities. The research described in this paper is an initial effort to develop a theory-driven approach to the characterization of visual entities. We enhance the state of the art in data visualization to characterize four (cid:179) comet (cid:180) designs. This work helps to understand visualization more precisely and provides a basis to help the designer to formally assess the effectiveness of their work
Documentos de Trabajo When more schooling is not worth the effort: another look at the dropout decisions of disadvantaged students in Uruguay

In Uruguay, similar to many developing countries, the economic return to lower secondary studies is low. When heterogeneity is introduced in the analysis, it can be shown that differences in the quality of education and in the probability of repetition mark the contrast between an attractive and an inconvenient investment in secondary education between advantaged and disadvantaged students. The values of internal rate of return computed for the Uruguayan case allow concluding that, paradoxically, lower secondary education is an inconvenient investment for disadvantaged students, even disregarding the possibility of them not being able to afford the opportunity costs, explaining the heavy dropout rates of this student type. These results cast some serious doubts on the fairness of compulsory schooling laws that are not accompanied by complementary policies to ensure equal learning outcomes across socioeconomic groups.
CARACTERIZAÇÃO DE POLIMORFISMOS NO GENE DGAT1 E NO GENE DA LEPTINA EM UMA POPULAÇÃO DE NOVILHAS NELORE

This study was conducted with 125 Nelore heifers from three different herds: selection (NeS), traditional (NeT), both selected for yearling weight, and control (NeC), selected for mean yearling weight, and had the objective of looking for PCR-RFLP’s polymorphisms in DGAT1 and LEPTIN genes. The herds analysed belong to the Zebu Breeding Program, of the Animal Breeding Experiment Station of Sertaozinho – SP – Brazil. The DNA was extracted from leukocytes by the saline protocol, and to amplify the gene fragments primers previously described were used. The PCR products were digested by restriction enzymes to detect the DGAT1 EaeI e LEPTINA BsaAI polymorphisms, and were submitted to electrophoresis. The DGAT1 allele (lisine) presented the larger frequency in the population. The highest frequencies of the DGAT1 were found in the NeS e NeT herds, respectively, followed by the DGAT1. Neither animal presented the DGAT1 genotype (alanine). Selected herds (NeS and NeT) allelic and genotypic frequencies for this locus were not significanttly different. Howerver, significant differences (p<0.05) were detected between the selected (NeS and NeT) and the control herds (NeC). In respect of the Leptin hormone, the allele frequencies were LEP A = LEP G = 0,50 in all the population. The LEP AG was the most frequent genotype in all the three herds. The control group (NeC) presented the LEP GG largest frequency, however, no significant differences were observed among the three herds for this locus. Key-words: DGAT1, LEPTIN, molecular markers, Nelore, RFLP.
HIGH FREQUENCY POWER CABLE MODELING FOR SCREEN VOLTAGE CALCULATION OF DIFFERENT CABLE LENGTH WITH INDUCTION MOTOR DRIVE SYSTEM (VFD)

This paper discussed on high frequency power cable modeling, simulation and analysis of the cable parameters variation. Also the variation of screen voltage, cable input and output phase voltage is discussed in the new developed power cable model. In this research paper, the input and output cable screen voltage are measured. The phase voltage for the different range of series inductance and shunt capacitance due affects the increasing cable length. The power cable parameters are accurately calculated for the cable connected between Variable Frequency Drive (VFD) and Induction Motor. An improved new high-frequency cable model is developed to represent the behaviors of cables connected between drive (VFD) and the motor terminal. The cable parameters and cable behavior is studied by mathematical functions in frequency domain. For different range of cable length are accounted in the new power cable equivalent circuit are developed and the same has been implemented and the results are presented in MATLAB/SIMULINK.
Abnormal Dielectric Behavior in Ti-Ni Spinel Ferrite

The dielectric constant ' and dielectric loss tangent tan were investigated as a function of frequency and temperature for the ferrite system TixNi1+xFe2-2xO4 (where 0≤x≤0.625). It was found that both ' and tan decrease with increasing frequency of applied electric field. The behavior of the dielectric constant with frequency was explained on the basis of hopping mechanism and Koops theory. It is noticed that dielectric constant decreases with increasing temperature up to certain temperature TMS after that increase. Then the metal/semiconductor transition temperature, TMS, was determined from '(F, T) plots. The loss tangent tan showed an abnormal behavior (loss peaks) with temperature and frequency for the pure and low substitution for the studied system. The loss peaks shifts to higher values of frequencies as temperature increases. The activation energy for dielectric relaxation showed an increase with increasing Ti and Ni contents. An attempt is made to explain the metallic like behavior and abnormal relaxation loss for the samples.
PREDICTIVE CHANNEL SCANNING AND SWITCHING ALGORITHM FOR THE COEXISTENCE OF IEEE 802.15.4 AND WIFI

Among the coexistence problems for the 2.4-GHz industrial, scienti(cid:12)c, and medical (ISM) band, interference between WiFi and IEEE 802.15. 4/ZigBee networks in particular has become a dominant problem because of the wide installation of WiFi access points (APs). This paper proposes a predictive channel scanning and switching (PCSS) algorithm that eﬃciently avoids WiFi interference. In this PCSS algorithm that is based on an IEEE 802.15. 4e-2012 multi-channel communication network, each device rapidly senses the interference and switches the channel. This paper evaluates the performance of PCSS by comparing it with existing methods and shows that PCSS is superior.
Discriminating N

In the quantum communication, a sender encodes an information through a quantum system and sends it to a receiver who may measure it and extract the information[1-3]. Unlike classical states, nonorthogonal quantum states cannot be perfectly discriminated by performing single measurement. Therefore, in the quantum communication, an optimized procedure is inevitable to discriminate quantum states. The optimization strategy is decided by the result of measurement. The result of measurement can be classified by the certainty in a decision of the given state by a measurement. For instance, if a receiver cannot say about the given state, the measurement is called to be a failure. If quantum states are linearly independent, by permitting the failure of measurement, one can make the confidence of guessing being one, which can eliminate the error of guessing. The strategy is called the unambiguous discrimination[4-7]. If quantum states are linearly dependent, the maximum confidence of guessing cannot be one. However, one can take a strategy of maximum confidence to each guessing, which is called maximum-confidence discrimination[8]. Meanwhile, one can use a minimum-error discrimination(MD)[9], where the failure of measurement is not allowed.
Ethanol synthesis by anoxic root segments from five cedar species relates to their habitat attributes but not their known differences in vulnerability to Phytophthora lateralis root disease

Ethanol synthesis by anoxic root segments from Port Orford cedar (Chamaecyparis lawsoniana (A. Murray bis) Parl. ); yellow cedar (Chamaecyparis nootkatensis (D. Don) Spach); Atlantic white cedar (Chamaecyparis thyoides (L.) Britton, Sterns & Poggenb. ); western redcedar (Thuja plicata Donn ex D. Don), and incense cedar (Calocedrus decurrens (Torr.) Florin ) was compared to determine whether the amounts that they produced during flooding could contribute the known greater vulnerability of Port Orford cedar to infection by Phytophthora lateralis Tucker & Milbrat. Roots were incubated in water at 5, 15, 25, and 35 °C for 14 days with periodic sampling. After 12 h of anoxic stress, Atlantic white cedar and yellow cedar roots produced equal quantities of ethanol that were about two times more than produced by the other three species, which did not differ from one another. The roots remained anoxic for 14 days, with ethanol concentrations increasing 6 to 11 times depending on the species. After 14 days, Atlantic .
Compatibility of the Results of an Automated Urine Analyzer with Urine Culture

Objectives: We aimed to evaluate incidence of leukocyte esterase (LE) and nitrite positivity, leukocyte and bacterial counts in urine, and Gram positive and negative bacterial results interpreted by an automated urine analyzer for compliance with culture results. Materials and Methods: 3194 urinalysis results were examined retrospectively. Measurements were made on Sysmex UF-5000 automated urine analyzer. Gram positive and negative bacterial interpretations were compared with results of culture. Results: Out of 889 patients with bacterial interpretation, 577 were Gram positive and 312 were Gram negative. There were 6 positive culture results in Gram positive group (2 E. faecalis, 4 S. Agalactia) and 61 positive culture results in Gram negative group (52 E. coli, 4 K. pneumoniae, 5 P. Aeuroginosa). As incompatible with results of culture, incorrect gram-stain interpretations were made by the analyzer in 3 samples (1 K. Pneumoniae, 2 Candida spp) in Gram positive group and in 3 samples (2 E. faecalis, 1 S. Agalactia) in Gram negative group. Rates of LE, nitrite positivity, leukocyte and bacterial counts were higher in Gram negative group. Conclusions: Especially Gram negative bacterial interpretation obtained from automated urine analyzers may be beneficial for rapid typing of bacteria and early treatment in urinary tract infections.
InP-based Photonic Integration Platform: Status and Prospects

Photonic integration has a key role in the further expansion of the information technologies and it is expected to result in the disruption of many industry sectors [1]. Such a transition promises to lower the energy consumption of optoelectronic systems as well as to enable a broad range of new applications. Multi Project Wafer (MPW) runs for photonics have been implemented during the last decade, which target the use of a generic integration technology with high functionality at low cost [2].
Do Personality Traits, Attitude, Education, and Self-Efficacy Impact on Entrepreneurial Intention of Vocational Students?

One of the Indonesian government missions is increasing the numbers of young entrepreneurs to reduce the unemployment rate. Therefore, entrepreneurial education is introduced in middle schools, particularly in vocational schools. On the other hand, regulators and practitioners in education field focus only on how to make the students be competence to be an employee, not an entrepreneur. This study is aimed to investigate what factors to predict students' intention of becoming an entrepreneur. This study employed four predictor variables: personality traits, attitude, entrepreneurial education, and self-efficacy. Indicators to measure each variable were adapted from prior studies. A survey had been conducted involving 215 participants from four vocational schools in Jakarta. The data are analyzed using Structural Equation Modelling concept. This study proves that attitude and selfefficacy had a significant impact towards entrepreneurial intention. Interestingly, personality traits and entrepreneurial education have no effect on entrepreneurial intention.

Out of 13 important safety issues that need to be regulated in detail, one main topic is the recording of accident and event data to clarify accidents involving automated vehicles in mixed traffic. In addition, the basis for the clarification of traffic offences is to be created.
EXCHANGE RATE VOLATILITY AND MACROECONOMIC PERFORMANCE IN SMALL ISLAND DEVELOPING STATES A PAPER PRESENTED AT THE UOM-WCP INTERNATIONAL CONFERENCE AT LE MERIDIEN, MAURITIUS ON 22 DECEMBER 2011

The purpose of the study is to provide an investigation into the impact of exchange rate volatility on the macroeconomic performance of Small Island Developing States (SIDS). Taking a sample of 15 SIDS, the present study analyses econometrically the impact of exchange rate volatility on major macroeconomic variables, viz economic growth, external trade and foreign direct investment on the SIDS. The paper first constructs the z-score measure, developed by Wolf et al (2003) as a measure of exchange rate volatility and employs data spanning the period 1999 to 2010 to analyse robust estimates in a static framework as well as in a dynamic and longitudinal data framework using the Generalised Method of Moments. It also analyses the impact of exchange rate volatility on macroeconomic performance of the economies. The OLS with robust standard errors results indicate that, exchange rate volatility impacts negatively on current account balance but positively on the growth rate of the economies studied. In a dynamic setting, however, exchange rate volatility does not influence the macroeconomic variables.
The Taming of the Shrew

Although the development of highquality coatings is in fact tricky, there are situations where statistical Design of Experiments (also called DoE or Experimental Design) can be employed effectively. Design of Experiments allows, amongst other things, a quick identification of promising components in the initial raw material screening. This speeds up the development considerably. So why are there so few examples of successful applications of DoE in the area of coatings? For one, high-quality coatings are complex mixtures. A thorough experimental exploration will therefore often require a large number of experiments. Another reason might be the lacking familiarity with the method. Even though the underlying concepts have been known for quite some time [1], many shy away from the seemingly difficult training: Statistics sounds scary2
Characterisation of genes involved in oogenesis in Drosophila melanogaster

Oogenesis is the process by which an oocyte (egg) develops to a point where it is capable of fertilisation. This process is complex, requiring many fundamental cellular and molecular interactions. The study of oogenesis is greatly facilitated in the fruitfly Drosophila melanogaster due to this organism's accessible morphology and the advanced understanding of its genetics and molecular biology. A reverse genetics approach has been adopted in this laboratory to investigate genes involved in oogenesis. This approach uses a P-element enhancer trap reporter system to provide clues to the temporal and spatial expression of genes. Molecular techniques are then used to clone genes situated near the enhancer trap in the genome with in situ hybridisation used to match cloned genes to the original reporter expression pattern. Occasionally an expression is observed from the in situ hybridisation that bears no relation to the reporter gene but is very interesting nonetheless. The work in this thesis stems from such an observation. We isolated a eDNA with an in situ hybridisation expression pattern that showed gene expression very early in oogenesis with rapid localisation of the transcript to the developing oocyte. Egg chambers at mid-stages of oogenesis exhibited localisation of the transcript to the anterior region of the developing oocyte while late stages of oogenesis showed strong expression in the nurse cells and loss of localisation in the oocyte. A number of localised transcripts are known to have crucial roles in axis determination in the developing oocyte and embryo. Work presented in this thesis shows that this gene encodes a class V unconventional myosin. Examples of this class have been described in mouse and yeast and there is evidence that they are involved in vesicle trafficking. Additional cDNAs were isolated and sequenced although no full length cDNAs were found. A PCR and genomic DNA cloning strategy was used to obtain most of the remaining coding sequence. Hybridisation to polytene chromosomes from the salivary glands of third instar larvae located the gene to the 43BC region on the right arm of the second chromosome. Results mapping the class V myosin to one of three genes in this region will be presented.
