Apoio à tomada de decisão e minimização da perda de matéria prima em processos de manufatura

O estudo a seguir tem por objetivo otimizar e tornar automatizado um sistema de manufatura que utiliza chapas como materia prima. A preparacao do processo de manufatura atraves do sistema CAM analisado atualmente possui diversas etapas que nao possuem comunicacao entre si, alem disso, exige um alto nivel de intervencao do usuario em suas tomadas de decisao. Esse processo deve ser unificado de forma a buscar um resultado aprimorado, com base nos criterios de otimizacao propostos. As etapas do processo de manufatura envolvendo chapas sao analisadas ao longo do trabalho, passando por etapas iniciais como a definicao das pecas que devem ser produzidas, etapas intermediarias como o processo de otimizacao de pecas (nesting) e sua respectiva parametrizacao, e a etapa final, ou seja, a obtencao do codigo NC para a producao das pecas. Para otimizar tais etapas, e proposto um sistema de apoio a tomada de decisao, com caracteristicas hibridas, formado por um sistema especialista e por tecnicas de otimizacao, tais como metaheuristicas. O metodo proposto aprimora os resultados atraves da parametrizacao automatizada utilizando o sistema de apoio a tomada de decisao, definindo a melhor parametrizacao com base nos produtos a serem manufaturados, reduzindo assim a necessidade de decisoes manuais e, por conseguinte, a interferencia do usuario no processo e, ainda, eliminando a necessidade do mesmo ser um especialista. Essa automacao deve analisar as possiveis chapas em estoque assim como parâmetros oferecidos pelo processo de nesting e buscar a melhor configuracao para o processo, analisando possiveis permutacoes. Alem disso, e proposta a adicao de um novo componente nas etapas de manufatura, responsavel por analisar as sobras aproveitaveis do processo e organizar a sucata gerada pelo mesmo, tornando-a disponivel para ser reutilizada futuramente. Analisando o SAD implementado, foi possivel observar que os resultados obtidos foram satisfatorios e, em muitos casos, superiores aos obtidos em outros testes realizados na literatura. Alem disso, a aceitacao do sistema pelos usuarios que realizaram os testes de performance e viabilidade de uso foi considerada excelente. Conforme apontado pelos usuarios, o numero de parâmetros a ser selecionado reduziu drasticamente, tornando assim o sistema mais simples de ser utilizado.
A method for fast mining abnormal state information of power equipment based on time series analysis

An approach based on time series analysis is proposed as means to mining the abnormal state information of power equipment. The state information is equivalent to the amount of time series of each state. Anomalies in time series are divided into two categories: anomaly caused by intervention, noise and missing values. Then based on the model fitting results, we get the type of anomaly in time series. Considering the noise points and missing value, the iteration method is used to clean data and improve its quality and availability. As to intervention, we introduce the in response structure to infer the existence of latent failures and achieve the early-warning of equipment condition. Finally, the approach is tested the on-line monitoring data of a transformer, with the results showing that this method can effectively identify anomaly and accomplish the goal of data cleaning and state early-warning.
Ante partum depression and husband's mental problem increased risk maternity blues

Maternity blues disorder (MB) is common, and it is usually undiagnosed. This study to identify several risk factors related to MB. Subjects were pregnant women who had antenatal and delivery at the Persahabatan Hospital (RSP) Jakarta from 1 November 1999 to 15 August 2001. Consecutive sampling and was followed-up until two-week postpartum. Those who ever had psychiatric disorders (schizophrenia or other psychotic disorders) were excluded. MB and ante partum depression (APD) detected by using Edinburgh Postnatal Depression Scale (EPDS). Husband’s mental status based on Symptom Check List-90 (SCL-90) respectively. Among 580 subjects, 25% suffering from MB. Compared with those who did not have APD, those who experienced it had more than three-fold increased risk to be MB [adjusted hazard ratio (aHR) = 3.57; 95% confidence interval (CI) = 2.54;5.03]. Those who had not healthy baby on the first 5 days afterbirth than who had healthy baby had twice increased risk to be MB (aHR = 2.21; 95% CI = 1.34 ; 3.66). Who had husband with problem in mental health had 1.9 increased risk to be MB (aHR = 1.91; 95% CI = 1.36 ; 2.68) . Stress during pregnancy had 1.6 increased risk to be MB (aHR = 1.59; 95% CI = 1.14 ; 2.25). To control MB, special attention should be paid to women who had APD history, who had unhealthy baby on 5 first days afterbirth, who had husbands’ mental health problems, and who had stress during pregnancy.

Fetal therapeutics‐challenges and responsibilities

It is possible to categorize fetal therapeutics into three medical goals: therapy directed at bringing the fetus to a stage of extrauterine viability as in the treatments of erythroblastosis fetalis and pregnancy complicated by diabetes mellitus; therapy directed at bringing the neonate to a stage of postnursery survival as with the use of agents administered to the mother to prevent physiologic hyperbilirubinemia and respiratory distress syndrome in the newborn infant; and therapy directed at bringing the infant to childhood and subsequent adulthood, such as changes in maternal nutrition, personal habits, and total environment. The advances in diagnosis, therapeutics, and prophylaxis of each of these diseases are derivatives of the successful application of present knowledge. Continued advancement requires increased information about the normal and pathologic processes of pregnancy, the degree of control that the fetus‐placenta exercises in regulating metabolic processes of the mother, the interdependence as well as independence of the fetal and maternal endocrine systems, and the time‐related specificity of fetal metabolic pathways. Furthermore, because most of the present prophylactic and therapeutic approaches are not enzyme‐ or process‐specific, appraisal of the steps taken by the physician managing the fetus and its environment requires a focus more refined than the relatively gross standard of perinatal survival or mere absence of disease.

Disordered CYP11B2 Expression in Primary Aldosteronism

Abstract Primary aldosteronism is the most common type of secondary hypertension affecting 6–10% of patients with primary hypertension. PA is mainly caused by unilateral hyperaldosteronism due to an aldosterone-producing adenoma, unilateral hyperplasia with or without micronodules or bilateral zona glomerulosa hyperplasias with or without macro or micronodules. The development of antibodies against the terminal enzyme of aldosterone biosynthesis (CYP11B2) has permitted the further characterization of normal adrenals and resected adrenals from patients with primary aldosteronism. Normal adrenals exhibit two different patterns of cellular expression of CYP11B2: young individuals display a relatively uniform expression of the enzyme throughout the zona glomerulosa while the adrenals of older individuals have dispersed CYP11B2-expressing cells but have more groups of cells called aldosterone-producing cell clusters (APCC). APAs exhibit different patterns of CYP11B2 staining that vary from uniform to homogeneous. There are also a proportion of cells within the APA that co-express different enzymes that are not normally co-expressed in normal individuals. Approximately 30% of patients with unilateral hyperaldosteronism do not have an APA, but either have an increased number of CYP11B2 expressing micronodules or hyperplasia of the zona glomerulosa. In summary, the studies reported in this review are shedding new light on the pathophysiology of primary aldosteronism. The wide variation in histopathological features of the adenomas and concurrent presence of APCCs raises the possibility that most cases of unilateral production of aldosterone actually might represent bilateral asymmetric hyperplasia with nodules frequently due to the development of somatic aldosterone-driving mutations.

Color-coding reveals tandem repeats in the Escherichia coli genome.

Genomic DNA contains a wide variety of repetitive sequences. In Escherichia coli, there have been several classes of repetitive sequences reported, some of which cluster as tandem repeats. We propose a novel method for analyzing symbolic sequences by two-dimensional pattern formation with color-coding. We applied this method for searching tandem repeats in the E. coli genome and found approximately 50 repeats with periods longer than 30 bases. The longest repeat has a period of 1267 bases.
Ambient pH sensing in filamentous fungi: Pitfalls in elucidating regulatory hierarchical signaling networks

In this article, the experiments used to construct the ambient pH‐signaling network involved in the secretion of enzymes by filamentous fungi have been reviewed, focusing on the phosphate‐repressible phosphatases in Aspergillus nidulans. Classic and molecular genetics have been used to demonstrate that proteolysis of the transcription factor PacC at alkaline ambient pH is imperative for its action, implying that the full‐length version is not an active molecular form of PacC. It has been hypothesized that the transcriptional regulator PacC may be functional at both acidic and alkaline ambient pH, in either the full‐length or the proteolyzed form, if it carries a pal‐dependent molecular tag. The products of the pal genes are involved in a metabolic pathway that led to the synthesis of effector molecules that tag the pacC product, perhaps facilitating its proteolysis. © 2013 IUBMB Life, 65(11):930–935, 2013
Tumour necrosis factor may contribute to the anaemia of malaria by causing dyserythropoiesis and erythrophagocytosis

Among the unexplained changes caused by malaria in several host species, including man and mouse, are erythrophagocytosis and dyserythropoiesis. In order to see whether tumour necrosis factor (TNF) could contribute to these changes we injected recombinant human TNF intravenously into mice made very susceptible to this monokine by low density infection with a mouse malaria (Plasmodium vinckei) or prior injection of an extract of Coxiella burneti. Appreciable erythrophagocytosis, involving nucleated erythroblasts as well as mature red cells, was observed in bone marrow preparations from TNF‐treated mice and those with severe illness due to P. vinckei, but in no other group. Dyserythropoiesis, involving irregularly‐shaped nuclei and karyorrhexis, had the same distribution. TNF at concentrations up to 8 ng/ml was detected in the serum of all mice with severe malaria, but not uninfected animals or those with light infections. These findings are consistent with TNF making an important contribution to erythrophagocytosis and dyserythropoiesis, and thus to anaemia, in malaria and other conditions.
Improving team structure and communication: a key to hospital efficiency.

HYPOTHESIS Improving team structure and heightening communication will help provide cost-effective and high-quality patient care for general surgery patients. DESIGN This study surveys teamwork initiatives and their effects on specific variables related to patient care. PATIENTS The study population comprised all patients admitted to the hospital's general surgery teams during 5 years 3 months. SETTING Tertiary care hospital. INTERVENTIONS A complete restructuring of the patient care team for general surgery patients admitted to the hospital. The intervention occurred midway through the study period. MAIN OUTCOME MEASURES Mean length of stay for general surgery patients as a marker of team efficiency and a standardized patient satisfaction survey. RESULTS The mean length of stay after initiation of the restructured care team was significantly shorter than before initiation. The significance was present despite a consistent patient acuity measure and was associated with a high patient satisfaction level. CONCLUSIONS Restructuring the patient care team yielded a decreased mean length of stay while maintaining a high level of patient satisfaction. This analysis helps validate a hospital-wide initiative to maintain a high level of patient care while increasing patient volume.

On combined ring convolutional coded quantisation and CPM for joint source/channel coding

A new trellis-based coded quantisation scheme using ring convolutional codes is presented. When it is combined with trellis-coded continuous phase modulation (TCCPM) with convolutional codes over rings, a powerful joint source and channel coding (JSCC) scheme can be formed. We investigate the additive white Gaussian noise (AWGN) channel and the Rayleigh fading channel. Optimal soft decoding for the proposed JSCC scheme is studied. The soft decoder is based on the a posteriori probability (APP) algorithm for TCCPM with ring convolutional codes. It is shown that these systems with soft decoding outperform the same systems with hard decoding especially when the systems operate at low to medium signal-to-noise ratio (SNR). It is demonstrated that the new trellis quantisation schemes based on ring convolutional codes is superior to conventional trellis-coded quantisation (TCQ) of the same complexity. The novelty of this work is in the development of a trellis-based quantisation method using ring convolutional codes and the use of a soft decoder and the APP algorithm for the combined systems.
Enzyme Linked Immunoassay for the Detection of Platelet Associated IgG

Summary. An enzyme linked immunoassay incorporating antihuman globulin coupled with alkaline phosphatase has been developed to measure platelet associated IgG (PAIgG). Using a method in which platelet IgG is extracted into the fluid phase after appropriate procedures, we were able to bind the ‘solubilized’ PAIgG to commercially obtained antihuman IgG (AHG) which had previously been coated onto polystyrene. The amount of PAIgG thus bound was subsequently measured by the addition of the enzyme reagent using p‐nitro phenyl phosphate as substrate. With this technique platelets from normal donors were found to have 2·6–17·4 ng/106 platelets (mean ± 2 SD). These values are higher than those obtained when assay systems using intact platelets are employed. Platelets from patients with immune thrombocytopenia had PAIgG values of 8·2–98·0 ng/106 platelets. In a few patients with disorders other than autoimmune thrombocytopenia (AITP) increased levels of PAIgG were also demonstrated. The assumption that increased PAIgG always represents platelet autoantibody may not be valid. The relevance of PAIgG as a parameter in the diagnosis and clinical management of patients with AITP is discussed.
The association between on-site cardiac catheterization facilities and the use of coronary angiography after acute myocardial infarction. Myocardial Infarction Triage and Intervention Project Investigators.

BACKGROUND During the past decade the use of coronary angiography after acute myocardial infarction has substantially increased. Among the possible contributing factors, the increasing availability of cardiac catheterization facilities was the focus of our investigation. METHODS We investigated whether the availability of cardiac catheterization facilities at an admitting hospital was associated with the likelihood that a patient would undergo coronary angiography. After adjusting for age, sex, cardiac history, and cardiac complications during hospitalization, we evaluated this association in 5867 consecutive patients with acute myocardial infarction admitted to 19 Seattle-area hospitals. We also assessed the association between the presence of on-site cardiac catheterization facilities and in-hospital mortality. RESULTS Patients admitted to hospitals with on-site cardiac catheterization facilities were far more likely to undergo coronary angiography (odds ratio, 3.21; 95 percent confidence interval, 2.81 to 3.67) than patients admitted to hospitals where transfer to another institution would be required to perform cardiac catheterization. Admission to a hospital with on-site facilities was more strongly associated with the use of coronary angiography than any characteristic of the patient. Although our study had limited power to detect differences in mortality, the availability of coronary angiography had no discernible association with in-hospital mortality rates (odds ratio for mortality among patients admitted to hospitals with on-site facilities vs. patients admitted to hospitals without such facilities, 0.88; 95 percent confidence interval, 0.71 to 1.09). CONCLUSIONS In this community-wide study, the availability of on-site cardiac catheterization facilities was associated with a higher likelihood that a patient would undergo coronary angiography. However, admission to hospitals with these facilities did not appear to be associated with lower short-term mortality.
Bases de Datos Semánticas

En 1992, cuando Tim Berners-Lee dio a conocer la primera version de la Web, su vision a futuro era incorporar metadatos con informacion semantica en las paginas Web. Es precisamente a principios de este siglo que inicia el auge repentino de la Web semantica en el ambiente academico e Internet. El modelo de datos semantico se define como un modelo conceptual que permite definir el significado de los datos a traves de sus relaciones con otros. En este sentido, el formato de representacion de los datos es fundamental para proporcionar informacion de caracter semantico. La tecnologia enfocada en las bases de datos semanticas se encuentra actualmente en un punto de inflexion, al pasar del ambito academico y de investigacion a ser una opcion comercial completa. En este articulo se realiza un analisis del concepto de base de datos semantica. Tambien se presenta un caso de estudio donde se ejemplifican operaciones basicas que involucran la gestion de la informacion almacenada en este tipo de base de datos.

Desta maneira, somente com o engajamento e a participacao dos professores, pode-se pensar em politicas educacionais de fato transformadoras.
Lokalizacija mobilnega robota s pomočjo večsmerne kamere

Roboti bodo v prihodnosti v veliki meri zamenjali clovesko delovno silo. Biti bodo morali cimbolj avtonomni, kar vklucuje tudi samostojno navigacijo po prostoru. Za uspesno navigacijo je potrebno najprej poznati svojo pozicijo v svetu. Obstaja veliko metod, ki se ukvarjajo z lokalizacijo. Obicajno te metode uporabljajo podatke zajete z globinskimi senzorji. V diplomskem delu se osredotocimo na lokalizacijo s pomocjo panoramskih slik zajetih z vecsmerno kamero. Lokalizacijo izvajamo s pomocjo statisticnih metod PCA, KPCA, CCA in KCCA. Iz ucnih slik s temi metodami izracunamo nizkodimenzionalne podprostore na katere jih potem tudi projeciramo. Tako dobimo model okolja, v katerem se robot nahaja. S tem modelom lahko napovemo predvidene lokacije testnih slik. Vse metode implementiramo za interaktivno lokalizacijo s pomocjo robota ATRV mini. Natancnost lokalizacije v delu tudi ovrednotimo in podamo nekaj predlogov za izboljsavo celotnega sistema.
Virtualization Sparks Security Concerns

Virtualization is rapidly becoming a standard technology for businesses. The technology lets a single PC or server simultaneously run multiple operating systems or multiple sessions of a single OS. The approach is thus becoming a common way for users to optimize their hardware utilization by maximizing the number and kinds of jobs a single CPU can handle. Organizations now face the challenge of securing virtualized systems, which are vulnerable to the same threats as physical systems, including intrusions and malware. Virtualized systems cannot always be secured the same way as physical systems. Many virtualized systems can run on the same machine, but each one might need a different security level. Thus, security cannot simply be applied across the entire machine, as is the case with typical physical systems.
