Threshold phenomena involving the connected components of random graphs and digraphs
Authors:   , Coulson Matthew John 
Published: October 2023

We consider some models of random graphs and directed graphs and investigate their behavior near thresholds for the appearance of certain types of connected components. Firstly, we look at the critical window for the appearance of a giant strongly connected component in binomial random digraphs. We provide bounds on the probability that the largest strongly connected component is very large or very small. Next, we study the configuration model for graphs and show new upper bounds on the size of the largest connected component in the subcritical and barely subcritical regimes. We also show that these bounds are tight in some instances. Finally we look at the configuration model for random digraphs. We investigate the barely sub-critical region and show that this model behaves similarly to the binomial random digraph whose barely sub- and super-critical behaviour was studied by Luczak and Seierstad. Moreover, we show the existence of a threshold for the existence of a giant weak component, as predicted by Kryven.
En aquesta tesi considerem diversos models de grafs i graf dirigits aleatoris, i investiguem el seu comportament a prop dels llindars per l'aparició de certs tipus de components connexes. En primer lloc, estudiem la finestra crítica per a l'aparició d'una component fortament connexa en dígrafs aleatoris binomials (o d'Erdos-Rényi). En particular, provem diversos resultats sobre la probabilitat límit que la component fortament connexa sigui sigui molt gran o molt petita. A continuació, estudiem el model de configuració per a grafs no dirigits i mostrem noves cotes superiors per la mida de la component connexa més gran en els règims sub-crítics i quasi-subcrítics. També demostrem que, en general, aquestes cotes no poden ser millorades. Finalment, estudiem el model de configuració per a dígrafs aleatoris. Ens centrem en la regió quasi-subcrítica i demostrem que aquest model es comporta de manera similar al model binomial, el comportament del qual va ser estudiat per Luczak i Seierstad en les regions quasi-subcrítica i quasi-supercrítica. A més a més, demostrem l'existència d'una funció llindar per a l'existència d'una component feble gegant, tal com va predir Kryven.

Authors:   , Rosich Oliva Albert 
Published: October 2023

The present work aims to increase the diagnosis systems capabilities by choosing the location of sensors in the process. Therefore, appropriate sensor location will lead to better diagnosis performance and implementation easiness. The work is based on structural models ands some simplifications are considered in order to only focus on the sensor placement analysis. Several approaches are studied to solve the sensor placement problem. All of them find the optimal sensor configuration.

The sensor placement techniques are applied to a fuel cell stack system. The model used to describe the behaviour of this system consists of non-linear equations. Furthermore, there are 30 candidate sensors to improve the diagnosis specifications. The results obtained from this case study are used to strength the applicability of the proposed approaches.
El present treball té per objectiu incrementar les prestacions dels diagnosticadors mitjançant la localització de sensors en el procés. D'aquesta manera, instal·lant els sensors apropiats s'obtenen millors diagnosticador i més facilitats d'implementació. El treball està basat en models estructurals i contempla una sèrie de simplificacions per tal de entrar-se només en la problemàtica de la localització de sensors. S'utilitzen diversos enfocs per tal de resoldre la localització de sensors, tot ells tenen com objectiu trobar la configuració òptima de sensors.

Les tècniques de localització de sensors són aplicades a un sistema basat en una pila de combustible. El model d'aquest sistema està format per equacions no lineals. A més, hi ha la possibilitat d'instal·lar fins a 30 sensors per tal de millorar la diagnosis del sistema. Degut a aquestes característiques del sistema i del model, els resultats obtinguts mitjançant aquest cas d'estudi reafirmen l'aplicabilitat dels mètodes proposats.
Detección y diagnóstico de fallos múltiples en sistemas dinámicos usando análisis de componentes principales no lineal y residuos estructurados
Authors:   , Rincón Charris Amílcar Alejandro 
Published: October 2023

In recent years the detection and diagnosis of faults in devices and processes has been a field of research and development that has been addressed from multiple perspectives: control engineering, artificial intelligence and statistics among others. Within each with a number of techniques: expert systems , neural networks, case-based reasoning , signal analysis, observers equations analytical redundancy based on consistency, but only considering the presence of multiple failures and no diagnosis. In this thesis the detection and diagnosis of multiple faults in dynamic systems using nonlinear analysis for the detection and diagnosis for structured waste components will be studied. The study includes the development of a mathematical model of a gas turbine mini SR -30 and implementation of algorithms for detection and diagnosis of multiple faults in the system.
The detection and diagnosis of multiple faults is more complex than the detection and diagnosis of single faults. This is not only because it increases the number of failures, but also because of the emergence of new phenomena that should be considered, such as a combination or interaction of faults, compensation, and the combinatorial explosion of possible failure scenarios. The problem of multiple failures is important, since the single fault assumption can lead to incorrect diagnoses when multiple faults occur.
En los últimos años la detección y el diagnóstico de fallos en dispositivos y en procesos ha sido un campo de investigación y desarrollo que se ha podido abordar desde múltiples perspectivas: la ingeniería de control, la inteligencia artificial y la estadística entre otros. Dentro de cada una de ellas con multitud de técnicas: sistemas expertos, redes neuronales, razonamiento basado en casos, análisis de señales, observadores, ecuaciones de redundancia analítica, diagnóstico basado en consistencia, pero considerando la presencia de fallos únicos y no múltiples. En esta tesis se estudiará la detección y el diagnóstico de fallos múltiples en sistemas dinámicos utilizando análisis de componentes no lineal para la detección y los residuos estructurados para el diagnóstico. El estudio incluye el desarrollo de un modelo matemático de una mini turbina de gas SR-30 y en la implementación de algoritmos de detección y diagnóstico de fallos múltiples en dicho sistema. La detección y el diagnóstico de fallos múltiples ha resultado ser más complejo que la detección y el diagnóstico de fallos únicos. Esto no es sólo porque aumenta el número de fallos, sino también debido a la aparición de nuevos fenómenos que deben ser considerados, tales como una combinación o la influencia mutua de los fallos, la compensación, y la explosión combinatoria de posibles escenarios de fallos. El problema de fallos múltiples es importante, ya que el supuesto de un solo fallo puede llevar a diagnósticos incorrectos cuando fallos múltiples ocurren.
Boundedness on generalized Morrey spaces for the Schrodinger operator with potential in a reverse Holder class
Authors: Wang Guiyun , Zheng Shenzhou 
Published: October 2023

In this article, we prove boundedness for the Hessian of a Schrodinger operator with weak regularity on the coefficients, and potentials satisfying the reverse H\"older condition. This is done in in generalized Morrey spaces, and in vanishing generalized Morrey spaces. On the Schrodinger operator \(L=-a_{ij}(x)D_{ij}+V(x)\) it is assumed that \(a_{ij}\in \rm{BMO}_{\theta}(\rho)\) (a generalized Morrey space) and that \(V(x)\in B^*_{n/2}\) (a reverse Holder class).

Authors: Helene Eng , Handegård Bjørn Helge , Patras Joshua 
Published: October 2023

Bakgrunn: Treatment Foster Care Oregon (TFCO) er en behandlingsmetode for ungdommer med alvorlige atferdsvansker og deres familier. Overordnet er målene å oppnå gode behandlingsresultater på ungdommens vansker, og at ungdommene skal kunne bo hjemme hos foreldrene. TFCO er en multisystemisk, koordinert behandlingsform, der man arbeider med flere relevante arenaer for ungdommen parallelt, som for eksempel familie, skole, psykisk helsehjelp og fritid. I behandlingsperioden bor ungdommen midlertidig i et fosterhjem, for så å flytte gradvis hjem til foreldrene. Nasjonalt utviklingssenter for barn og unge (NUBU) har ansvaret for metoden i Norge.
Metode: Denne kunnskapsoppsummeringen bygger på et systematisk litteratursøk i databasene Embase, Medline og Psykinfo, NORART, Cochrane, Cristin, NORA, SCOPUS og SweMed. Det er også søkt i internasjonale kunnskapsdatabaser om evidens samt innhentet informasjon om tiltaket fra tiltakseier. Litteratursøk og annen innhentet informasjon ble gjennomgått for å identifisere nordiske effektstudier, internasjonale oppsummeringsstudier og eventuelt andre norske studier om tiltaket.
Resultater: Resultatene består av en vurdering av tiltakets beskrivelse, foreliggende effektstudier, forskningsmetodisk kvalitet og implementeringskvalitet. I denne kunnskapsoppsummeringen identifiserte vi 2 nordiske effektstudier samt 14 internasjonale oppsummeringer og vurderinger i databaser om tiltaket. Samlet sett synes studiene å kunne dokumentere effekter på kriminalitet, antall dager i innelåste betingelser, negativ atferd og rusproblemer. Det er noe mer uklart om tiltaket har effekter på psykososiale utfallsmål.
Konklusjon: TFCO klassifiseres på nivå 4 som et tiltak med tilfredsstillende dokumentasjon på effekt.

Published: October 2023

Background: Nutritional status is considered the best indicator and a non-clinical approach to optimizing a child’s health care. It does not only directly reflect the socioeconomic status of the family but also, the efficiency of the health care system. The study aimed to assess clinical features and nutritional patterns in an apparently healthy pediatric age group.
Methods: The study was a descriptive cross-sectional design carried out among school children aged 6 to 12 years. A multi-stage sampling method was used. A semi-structured questionnaire was used for sociodemographic data. Physical examination for signs of malnutrition and anthropometry was done. Feeding patterns and types of meals were recorded. The WHO growth charts and BMI-for-age charts were used to compute Z-score (weight-for-age, height-for-age and BMI-for-age) and classify children into levels of nutritional status. Data were analyzed using SPSS version 21 and p-value < 0.05.
Results: It was observed that forty-seven percent of children were from a <4 family size, with the majority belonging to the middle socio-economic class. The majority had normal height and weight, while 8.8% were stunted and 4.3% were underweight. On a daily basis, 95% of the children feed 3 to 4 times and 91% consume essential nutritional diets. 26.3% of the children had a persistent cough, 14.5% had persistent diarrhea, 14% had a fever, 10.3% had abdominal pain, and 3.8% were on routine medications.
Conclusion: This study showed that most of the children had normal height and weight and their feeding pattern was adequate, although some were stunted and underweight and had disease symptoms. The fact that they appear healthy and are not present in the hospital does not suggest the absence of diseases. It is therefore important to do regular checkups for these children so as to monitor their growth, improve their health and prevent diseases.

Abstract

Objectives
The purpose of this study was to examine, by sex, whether precarious workers in Japan receive less support in the workplace than permanent workers.

Methods
We conducted a cross-sectional study using an online questionnaire in 2022. We stratified participants by sex and performed modified Poisson regression analysis. The outcomes were support from supervisors, co-workers, occupational health professionals, and no one. Adjusted prevalence ratios (aPR) were calculated for contract workers, part-time workers, and dispatched workers, using permanent workers as reference.

Results
This study had 21 047 participants. For men, 87.9% were permanent workers; for women, 50.7% were permanent workers and 37.3% were part-time workers. For workplace support, 47.5% of men and 45.2% of women selected superiors; 41.8% of men and 50.5% of women selected colleagues; 16.8% of men and 6.2% of women selected occupational health professionals. Female contract workers were less likely to receive support from their supervisors (aPR 0.88) or co-workers (aPR 0.89). Male part-time workers were less likely to be supported by their co-workers (aPR 0.86). Dispatched workers were less likely to be supported by their supervisors (men aPR 0.71, women aPR 0.84) and co-workers (men aPR 0.73, women aPR 0.77). Part-time and dispatched workers were less likely to receive support from occupational health professionals.

Conclusions
Precarious workers could get less workplace support than permanent workers. This may contribute to occupational health problems with precarious workers.
