Taxonomy of the manufacturing strategies of large Spanish industrial companies

This work presents a classification of the manufacturing strategies of large Spanish industrial companies in Spain. For this purpose the various international empirical studies on alternative manufacturing strategies have been taken as a reference, reviewed and compared. The database used in this study is made up of information on 114 factories and has been designed using the information from a survey mailed to the industrial companies which have production plants in Spain and which in the financial year of 1994 (reference date of this research) employed over 200 workers. Cluster analysis methodology has been used and the classification criterion taken was the competitive advantages or strengths of each factory concerning the five competitive priorities in manufacturing: efficiency, flexibility, quality, delivery and customer service. Finally, this work identifies a taxonomy of the manufacturing strategies of a sample of the largest industrial companies in Spain, differentiating three alternative producti.
Value analysis as a decision support tool in cruise ship design

In the cruise ship industry product development and production activities are really complex and must follow strict rules imposed by naval registries. Designers are frequently required to choose among several alternative solutions (e.g., materials, components, layouts, etc.). Because of time constraints, as a matter of fact, design decisions are made fast and in a reactive way, according to the particular case, without considering decisions made in the past and without using specific decision support tools. The final choice is often left to a single designer's experience, whose selection criteria are unknown and not formalised. As a consequence there is no shared knowledge justifying the reason why a design solution has been chosen and whether it is the best one. We developed and implemented in Fincantieri S.p.A. – a leading company in the cruise ship industry – an original decision support tool, based on value analysis, designers can use to document and formalise their choices. Value analysis is a well known structured method to increase product value and/or cut costs, thus supporting the selection of the most valuable solution by means of objective parameters. We demonstrate that the proposed tool can also facilitate reuse of the available knowledge base on decisional criteria, increase interactions between people (design staff, buyers, shipyard personnel, etc.) involved in different stages of different value analysis projects, and reduce decision time.
Closed-Form Expressions for the Current or Charge Distribution on Parallel Strips or Microstrip

Simple but accurate closed-form expressions for the charge and current distributions on parallel-plate stripline or microstrip are given. This form is convenient for use in various applications, such as determining radiation or mode fields of the lines, or frequency dispersion of the fundamental mode of the microstrip. These expressions are used to obtain explicit expressions for the capactitance of these lines, accurate to within one percent of the actual value for any ratio of stripwidth to spacing.
Predictor and Saverity Caries in HIV/AIDS Patient and Relationship with Antiretroviral Therapy (ARV)

Clinical findings about the adverse effects of the use of antiretroviral drugs in the oral cavity of people with HIV / AIDS began to be found. A case regarding the side effects of the use of antiretroviral drugs is the discovery of oral cavity lesions in the form of whitish plaque on the lips and right buccal mucosa that has occurred more than one month accompanied by complaints of taste disorders, xerostomia, and a burning feeling in the mucosa of patients using Nevirapine, Zidovudine and Lamivudine. This study was to analyze the relationship of anti-retroviral treatment in HIV AIDS sufferers to caries predictors, and caries severity, and analyze the relationship between the duration of antiretroviral treatment to caries predictors and caries severity. This study used an observational method with cross sectional or cross sectional design by conducting direct observations, on 100 samples of HIV / AIDS sufferers using anti-retroviral drugs at the Yayasan Peduli Kelompok Dukungan Sebaya (YPKDS) Makassar held in October 2019. Data were analyzed with chi square test.
Optical amplifier noise-figure reduction using a variable polarisation beam splitter

A 3 dB noise figure (NF) reduction of an Er3+-doped fibre amplifier (EDFA) has been experimentally demonstrated using a variable polarisation beam splitter (VPBS). A VPBS controlled by two liquid crystal cells adequately separates half the amplified spontaneous emission (ASE) power of the optical output signal from the optical amplifier and reduces the NF by up to 3 dB. This technique is verified in an EDFA with a measured NF reduction of 3 dB. It yields an EDFA with an NF of 1.2–1.7 dB and gain of 32–34 dB over a wide spectral bandwidth.
Fault Diagnosis of an Induction Generator in a Wind Energy Conversion System Using Signal Processing Techniques

Abstract In this article, a contribution to fault diagnosis of an induction machine in a wind energy conversion system in closed-loop operation using a combination between short-time Fourier transform and discrete wavelet transform algorithms is proposed. An on-line fault diagnostic technique based on stator currents analysis of the squirrel-cage induction generator is proposed to detect and localize abnormal electrical conditions that indicate, or may lead to, a stator or rotor failure in a squirrel-cage induction generator. This technique also permits identification of a fault severity factor and consequently helps to determine the best choice of corrective maintenance. Furthermore, a generalized model of the squirrel-cage induction generator is used to simulate both the rotor and stator faults, taking iron losses, main flux, and cross-flux saturation into account. The efficiency of diagnostic procedure in closed-loop operation of the wind energy conversion system under non-stationary operating conditions is illustrated with simulation results.

Interactive effects of leader justice and support for safety on safety performance

Purpose – The purpose of this paper is to examine the main and interactive effects of general and safety-specific leader justice (SSLJ) (i.e. fair treatment) and leader support for safety (LSS) on safety performance. Design/methodology/approach – Two independent samples of construction workers rate their leaders with regards to fair treatment and support for safety and report their own safety performance in a survey. Findings – In both studies, LSS significantly moderated relationships of both general and SSLJ with safety performance. In Study 1, the strength of relationship between general leader justice and safety performance increases while LSS is increased. Similar pattern was found for the relationship between SSLJ and safety performance in Study 2. Practical implications – Safety interventions targeting leadership should consider training for leader safety practices that are perceived as supportive and fair. Originality/value – The research is unique in its examination of leader justice in a safety-.
Effect of Proactive Personality on Career Decidedness: The Mediating Role of Career Exploration and the Moderating Role of Anticipated Regret

In order to deepen the understanding of the personality antecedents of students’ career decidedness, this study, based on social cognitive career theory and career development theory, examined the effect of proactive personality on career decidedness as well as the mediating mechanism and moderating factors in this process. The results of the survey of 783 Chinese college students showed that proactive personality was positively related to career decidedness via career exploration, and anticipated regret moderated the relationship between proactive personality and career exploration significantly. Both theoretical and practical implications are discussed at the end of this research.
Characterization of monolithic n-type 6H-SiC piezoresistive sensing elements

Monolithic, junction isolated piezoresistors have been fabricated in commercially available 6H-SiC. The gauge factor (GF) of these elements has been measured up to 250/spl deg/C in both longitudinal and transverse configurations. The maximum GF observed was -29.3, corresponding to the piezoresistive coefficient /spl pi//sub 11/. A beam transducer with a four-arm integral piezoresistor network was fabricated and tested in a force sensor configuration. The data indicate that, n-type 6H-SiC has the potential to be useful in high temperature electromechanical sensors to measure parameters such as pressure, force, strain and acceleration. >
Genetic Diversity of Genes Controlling Unilateral Incompatibility in Japanese Cultivars of Chinese Cabbage

In recent years, unilateral incompatibility (UI), which is an incompatibility system for recognizing and rejecting foreign pollen that operates in one direction, has been shown to be closely related to self-incompatibility (SI) in Brassica rapa. The stigma- and pollen-side recognition factors (SUI1 and PUI1, respectively) of this UI are similar to those of SI (stigma-side SRK and pollen-side SP11), indicating that SUI1 and PUI1 interact with each other and cause pollen-pistil incompatibility only when a specific genotype is pollinated. To clarify the genetic diversity of SUI1 and PUI1 in Japanese B. rapa, here we investigated the UI phenotype and the SUI1/PUI1 sequences in Japanese commercial varieties of Chinese cabbage. The present study showed that multiple copies of nonfunctional PUI1 were located within and in the vicinity of the UI locus region, and that the functional SUI1 was highly conserved in Chinese cabbage. In addition, we found a novel nonfunctional SUI1 allele with a dominant negative effect on the functional SUI1 allele in the heterozygote.
Red and processed meat consumption and food insecurity are associated with hypertension; analysis of the National Health and Nutrition Examination Survey data, 2003–2016

Supplemental Digital Content is available in the text Objective: This study examined the joint association of red and processed meat intake and food insecurity with hypertension. Methods: Adult participants of the National Health and Nutrition Examination Survey 2003–2016 were included. Total red meat intake was estimated using 24 h dietary recalls. Food insecurity was defined as having three or more affirmative responses using the Food Security Survey Module. Hypertension was defined as having mean SBP of at least 130 mmHg or DBP of at least 85 mmHg or use of antihypertensive drugs. Multivariable surveylogistic regression models were used to examine the independent and joint associations of total red meat and food insecurity with hypertension. Results: A total of 31 314 participants [mean (SE) age of 46.8 (0.3) years] were included, of whom 18.3% were food insecure. Total red meat consumption and food insecurity were independently associated with higher odds of hypertension. Compared with the first quintile of total red meat intake, participants in the fourth and fifth quintiles of total red meat intake had 29 and 39% higher odds of hypertension, respectively (P = 0.003). These associations were stronger among food insecure participants (P value for interaction <0.001). Substituting one serving/day of poultry, fish, eggs, dairy products, or plant-based protein sources for total red meat was each associated with 8–15% lower odds of hypertension. Conclusion: This study provides further evidence regarding the health hazards of total red meat consumption in relation with hypertension and calls for more awareness among food insecure groups.

Damage assessment of structure using incomplete measured mode shapes

A global algorithm for damage detection and assessment of structures based on parameter estimation method using finite element analysis and measured modal response of the structure is presented. Damage is considered as a change in the structural stiffness parameters. Modal displacements (eigenvector) of a structure are characterized as a function of structural parameter that yields an indeterminate set of equations. Elemental damage equations which relate partially measured mode shape of the damaged structure to the change of structural parameter are developed using incomplete measured mode shapes. Based an optimization method these equations are solved to find changes of the structural parameters. Subsequently, Monte Carlo simulation is applied to study the sensitivity of this method to noise in measured modal displacements. The algorithm is tested in numerical simulation environment using a truss and a frame model. Results show the high capability of this method to detect damages of the structures when noise is present.

Algorithm level evaluation of cryptosystem resistance to second-order DPA

In a previous study, we verified by simulation at the transistor level that the difference in power consumptions in Differential Power Analysis (DPA) can be approximated by using the Hamming weight of the bit string that includes an attacked bit position. Based on that verification, we proposed an algorithm-level method for evaluating the resistance of cryptosystems to DPA attacks and demonstrated the effectiveness of the method by applying it to a first-order DPA-resistance evaluation of Data Encryption Standard (DES) implementations. In this paper, we apply this method to second-order DPA and show that the simulation results are consistent with the experimental results of attacks against a smartcard. We also show that using the simulation method we can quantitatively evaluate the resistance of the DES algorithm and its countermeasures to second-order DPA. This method is faster than other methods used at the RTL and downstream levels and is useful for quantitatively evaluating the resistance of countermeasures to DPA at the upstream level of cryptosystem design.
Laboratory measurements and models of modern loads and their effect on voltage stability studies

Accurate load models are important in determining the status of a power system when subjected to sudden or gradual changes in operating conditions. This paper describes laboratory measurements and derived models of modern loads subjected to large voltage changes and their effect on voltage stability studies. Low-voltage, long-time models of loads such as modern air conditioners, discharge lighting and devices containing electronic-regulated power supplies were developed. One means used by utilities to avert voltage collapse has been system voltage reduction. The characteristics of modern loads and controls reduces the effectiveness of this voltage reduction. The results indicate the importance of using accurate load models, especially for large industrial loads where the load composition can be identified.
An RF circuit model for carbon nanotubes

We develop an rf circuit model for single walled carbon nanotubes for both dc and capacitively contacted geometries. By modeling the nanotube as a nano-transmission line with distributed kinetic and magnetic inductance as well as distributed quantum and electrostatic capacitance, we calculate the complex, frequency dependent impedance for a variety of measurement geometries. Exciting voltage waves on the nano-transmission line is equivalent to directly exciting the yet-to-be observed one dimensional plasmons, the low energy excitation of a Luttinger liquid.
Aspirin-triggered resolvin D1 reduces parasitic cardiac load by decreasing inflammation in a murine model of early chronic Chagas disease

Background Chagas disease, caused by the protozoan Trypanosoma cruzi, is endemic in Latin America and is widely distributed worldwide because of migration. In 30% of cases, after years of infection and in the absence of treatment, the disease progresses from an acute asymptomatic phase to a chronic inflammatory cardiomyopathy, leading to heart failure and death. An inadequate balance in the inflammatory response is involved in the progression of chronic Chagas cardiomyopathy. Current therapeutic strategies cannot prevent or reverse the heart damage caused by the parasite. Aspirin-triggered resolvin D1 (AT-RvD1) is a pro-resolving mediator of inflammation that acts through N-formyl peptide receptor 2 (FPR2). AT-RvD1 participates in the modification of cytokine production, inhibition of leukocyte recruitment and efferocytosis, macrophage switching to a nonphlogistic phenotype, and the promotion of healing, thus restoring organ function. In the present study, AT-RvD1 is proposed as a potential therapeutic agent to regulate the pro-inflammatory state during the early chronic phase of Chagas disease. Methodology/Principal findings C57BL/6 wild-type and FPR2 knock-out mice chronically infected with T. cruzi were treated for 20 days with 5 μg/kg/day AT-RvD1, 30 mg/kg/day benznidazole, or the combination of 5 μg/kg/day AT-RvD1 and 5 mg/kg/day benznidazole. At the end of treatment, changes in immune response, cardiac tissue damage, and parasite load were evaluated. The administration of AT-RvD1 in the early chronic phase of T. cruzi infection regulated the inflammatory response both at the systemic level and in the cardiac tissue, and it reduced cellular infiltrates, cardiomyocyte hypertrophy, fibrosis, and the parasite load in the heart tissue. Conclusions/Significance AT-RvD1 was shown to be an attractive therapeutic due to its regulatory effect on the inflammatory response at the cardiac level and its ability to reduce the parasite load during early chronic T. cruzi infection, thereby preventing the chronic cardiac damage induced by the parasite.
Identification of Material Properties Using FEMU: Application to the Open Hole Tensile Test

This article presents an application of identification via finite elements model update (FEMU) to experimental fields of a plate with a hole using stereo correlation. The presentation includes the evolution of material properties during a tension test, and a first approach in estimating statistical confidence intervals from a single experimental field. These are accomplished by characterizing the material at different load cases, and by repeating the identification multiple times for random samplings of the full field and for random redistributions of noise.
Improved Cascaded H-Bridge Multilevel Inverters with Voltage-Boosting Capability

This paper proposes two improved cascaded H-bridge (ICHB) multilevel inverters that feature voltage-boosting capability. The conventional H-bridge with a front-end dc–dc boost converter was restructured for single-stage operation. The developed three-level topology not only saves one power switch but also exhibits lower voltage stress across its capacitor. Extension to five-level generation was also introduced by merely adding two power switches and one capacitor. The final five-level topology outperforms the classical cascaded H-bridge (CHB) multilevel inverter with a significant reduction in the power switch count, with a 42% and 50% reduction in both the isolated dc source and inductor counts. The power efficiency was also improved without compromising the modularity feature of the classical CHB multilevel inverter. The operation and theoretical analysis of the proposed topologies were validated via simulations and experimental tests.
BengSentiLex and BengSwearLex: creating lexicons for sentiment analysis and profanity detection in low-resource Bengali language

Bengali is a low-resource language that lacks tools and resources for various natural language processing (NLP) tasks, such as sentiment analysis or profanity identification. In Bengali, only the translated versions of English sentiment lexicons are available. Moreover, no dictionary exists for detecting profanity in Bengali social media text. This study introduces a Bengali sentiment lexicon, BengSentiLex, and a Bengali swear lexicon, BengSwearLex. For creating BengSentiLex, a cross-lingual methodology is proposed that utilizes a machine translation system, a review corpus, two English sentiment lexicons, pointwise mutual information (PMI), and supervised machine learning (ML) classifiers in various stages. A semi-automatic methodology is presented to develop BengSwearLex that leverages an obscene corpus, word embedding, and part-of-speech (POS) taggers. The performance of BengSentiLex compared with the translated English lexicons in three evaluation datasets. BengSentiLex achieves 5%–50% improvement over the translated lexicons. For identifying profanity, BengSwearLex achieves documentlevel coverage of around 85% in an document-level in the evaluation dataset. The experimental results imply that BengSentiLex and BengSwearLex are effective resources for classifying sentiment and identifying profanity in Bengali social media content, respectively.
MEASUREMENT OF PEAK FORCE EXPERIENCED BY MALES DURING ASSISTED AND UNASSISTED PULL-UPS

The purpose of this study was to measure the peak force (PF) generated by males while performing assisted pull-ups (APU) and unassisted pull-ups (UPU) with pronated (PUP) and supinated (SUP) hand grips. Twenty-five men (mean ± SD: age= 23 ± 3 y; height= 180 ± 6 cm; weight= 88 ± 14 kg, APU: N=12, UPU: N=13) participated. Participants performed 2 sets of 10 pull-ups (PU) (1 PUP, 1 SUP) in randomized order on a PU bar attached to a force plate. PF generated during each PU was normalized to body weight (BW). There was no significant difference in PF generated between grips (P = 0.158) but there were significant differences in the PF generated over the course of 10 repetitions (P<0.001) and between the APU and UPU groups (P<0.001). On average the APU group lifted 114% of their BW and the UPU group lifted 151% of their BW.
