Anàlisis de sensibilidad con comportamiento no lineal del material y su aplicación en el diseño asistido de estructuras
Authors:   , Gil Espert Lluís
Published: October 2023

El contenido de la tesis que se presenta se ha organizado de la manera siguiente:

A lo largo del capítulo 2 se describen los aspectos generales del estado del arte del análisis de sensibilidad, centrándose en las principales metodologías existentes y en el cálculo elástico. Asimismo, se exponen un conjunto de reflexiones acerca de la bondad del análisis de sensibilidad.

En el capítulo 3 se explican los distintos acercamientos, en términos generales, que existen en la bibliografía sobre el cálculo de sensibilidades para modelos no lineales del material.

El capítulo 4 contiene las aportaciones de otros autores al desarrollo de formulaciones para estudiar la sensibilidad de la respuesta elastoplástica. Después de unas reflexiones críticas, se aborda una nueva formulación de sensibilidad de formas en cálculo elastoplástico con la notación usual en el contexto del análisis por elementos finitos en la ingeniería. A continuación, se prueba dicha formulación en un conjunto de ejemplos y se descubren algunas problemáticas que conlleva el análisis no lineal a solicitación constante.

En el capítulo 5 se desarrolla la formulación para el análisis de sensibilidad de formas en un modelo de daño incorporando la herramienta de cálculo de la longitud de arco, basada en el control de desplazamientos. Se realizan una serie de reflexiones sobre las posibilidades de extrapolación de cargas últimas y se prueban los algoritmos propuestos en un conjunto de ejemplos de diversa índole.

Después de un breve estado del arte sobre el diseño en ingeniería, se aborda en el capítulo 6 el problema del concepto de diseño asistido. Se realiza una propuesta conceptual para enlazar las posibilidades cuantitativas de un análisis de sensibilidad con la inteligencia artificial de los sistemas expertos. La intención es producir una nueva serie tecnológica de instrumentos de apoyo al diseño que mejoren las prestaciones de los existentes a tres niveles: análisis crítico de resultados, potenciación de la creatividad y aprendizaje heurístico.

Finalmente, en el capítulo 7 se describe la evolución de la programación y su relación con los elementos finitos. Se hace hincapié en los códigos orientados a objeto y se describen las aplicaciones prácticas de desarrollo que se han llevado a cabo en esta tesis.

El capítulo 8 y último contiene las conclusiones del trabajo desarrollado y las nuevas líneas de investigación que se proponen.
Un método de elementos finitos para análisis hidrodinámico de estructuras navales
Authors:   , García Espinosa Julio
Published: October 2023

La predicción precisa de los efectos producidos por el acoplamiento fluido estructura para cuerpos parcial o totalmente sumergidos, incluyendo superficies libres, es un problema de gran relevancia en la ingeniería naval así como en muchos otros campos del diseño de estructuras sometidas a la acción de fluidos.
Las dificultades que se encuentran en la resolución de los problemas de interacción fluido estructura se deben principalmente a las siguientes causas:

1. La dificultad de resolver numéricamente las ecuaciones de la dinámica de un fluido incompresible que, en general, si descartamos el caso más simple del modelo del flujo potencial, tienen un importante carácter no lineal.

2. Los obstáculos que se presentan al resolver la ecuación de la superficie libre, que constriñen el movimiento de las partículas a una superficie fluida de posición a priori desconocida.

3. Las dificultades asociadas a la resolución del problema del movimiento de un cuerpo sumergido debido a las fuerzas de interacción, minimizando la deformación de los elementos de la malla y reduciendo, de esta manera, la necesidad del remallado.

En la presente tesis se presenta un método estabilizado basado en el método de los elementos finitos que pretende solventar cada uno de los problemas anteriores. La metodología se basa en la modificación de las ecuaciones diferenciales de la dinámica de fluidos que gobiernan el flujo viscoso incompresible y el movimiento de la superficie libre, mediante la aplicación del método de cálculo finitesimal (FIC) propuesto en este trabajo.
En el presente caso las ecuaciones modificadas son resueltas usando un esquema de pasos fraccionados semi-implícito y el método de los elementos finitos (FEM).
El movimiento del cuerpo sumergido en el fluido debido a las fuerzas de interacción se calcula resolviendo un problema estructural dinámico, para el cual las fuerzas del fluido son las condiciones iniciales. Se incluye, además, un algoritmo para el movimiento de la malla debido a la deformación del dominio de cálculo. Este método minimiza la distorsión de la malla debida al movimiento del sólido rígido y al cambio de posición de la superficie libre. Este algoritmo se basa en la solución iterativa por el método de elementos finitos de un problema lineal, donde la malla de cálculo se considera un sólido elástico sometido a la deformación prescrita por el cambio en el dominio de cálculo. Las características de elasticidad del sólido, y en concreto su rigidez, se aplican de manera que los elementos que más se deforman tienen una rigidez mayor.
Por último se presentan varios ejemplos de interés industrial, aplicación de la metodología propuesta en diferentes campos de la ingeniería naval.
Diagnosi i innovació en els processos de producció i gestió energètica en equipaments turístics de les Illes Balears
Authors:   , Moià Pol Andreu Antoni
Published: October 2023

This PhD analyzes the touristic facilities and proposes improvements in the energy process production and management of hotels. During the last years there have been changes related to social, economic, legislation and environment aspects that have produced a change in building designs and the process and energy systems.
The tourist sector has more than 50 years in the Balearic Island's and has reached a level of maturity than allows for analysis and rethinking on energy production schemes. For this reason it's important to find a criterion of typologies of hotels and innovate in the design, management and production of energy. This can result a tool to be used to designers in the initial phase, for choose the architecture than reduce more the environment impacts, and be used to the public administration, users and managers for taking correct decisions.

 La tesi analitza els establiments turístics i vol proposar millores en els processos de producció i gestió energètica dels equipaments turístics. En els darrers anys s’han produït canvis socioambientals, econòmics i legislatius que han provocat un canvi en els edificis, fent que s’estableixin noves estratègies i dissenys en els processos i sistemes de producció energètica.El sector turístic te més de 50 anys d’implantació a les Illes Balears, ja ha arribat a un grau de maduresa suficient per poder ser analitzat i reflexionar sobre el seu futur en l’ús de l’energia. És per aquesta raó que trobar un criteri de tipologies d’hotels i propostes d’innovació en el disseny, la gestió i producció de l’energia pot resultar una eina que serveixi de suport tant als dissenyadors en l’etapa inicial, per a tal de seleccionar l’arquitectura que redueixi els impactes ambientals, com també serveixi a l’administració pública, als usuaris i gestors a l’hora deprendre decisions.
Comparative Analysis of Support Vector Machine and Convolutional Neural Network for Malaria Parasite Classification and Feature Extraction
Authors: Rosnelly Rika , Riza Bob Subhan , S. Suparni
Published: October 2023

Malaria is a dangerous infectious disease because, if it is slow to handle, it can even cause death. Malaria is caused by a parasite called plasmodium, which is transmitted through the bite of a malaria mosquito called Anopheles. Parasites transmitted by mosquitoes attack human blood cells. The inspection method used to identify the type of malaria parasite is microscopic examination, whose accuracy and efficiency depend on human expertise. Examination methods using the Rapid Diagnostic Test (RDT) and Polymerase Chain Reaction (PCR) are not affordable, especially in underprivileged areas. This study compares the performance of classification methods, namely Support Vector Machine (SVM) and Convolutional Neural Network (CNN), to identify the type of malaria parasite and its stage and develop a feature extraction algorithm. The method of feature extraction is a decisive step to identifying the type of malaria parasite. The feature extraction process by developing a feature extraction algorithm is called the PEMA and KEHE feature tracking algorithm, or feature tracking with perimeter, eccentricity, metric, area, contrast, energy, homogeneity, and entropy. The classifier uses a convolutional neural network (CNN) to divide the samples into 16 classes. The experiment used 446 images of malaria parasites. The outcome of identification showed that by tracking the PEMA and KEHE features with the SVM classifier, the best accuracy value was 85.08%, compared to CNN with an accuracy value of 61.40%.

Literacy Research and Its Relationship with Policy: What and Who Informs Policy and Why Is Some Research Ignored?
Authors: Papen Uta
Published: October 2023

Socio-cultural and practice-based approaches to literacy, associated with the (New) Literacy Studies, having emerged in the 1980s, nowadays are an established research field. Based on in-depth research, in many contexts and countries, the (New) Literacy Studies has much to offer to teachers and policymakers. And yet this impressive body of work has had little impact on policy. Taking as my example England, I ask what research has shaped policy in the past 30 years and why socio-cultural and practice-based studies have been ignored. Thus, I address the question of where the field has been and where it should go to from the point of view of its relationship with policy. My focus is on the initial teaching of literacy in primary (elementary) schools. I discuss three factors which I believe contribute to our struggles to influence policy: the policy environment itself and how it has changed; the wider economy of literacy research and what knowledge counts in the interface between research and policy; and, finally, the role of the media and public discourse in the relationship between research and policy. I end with questions about what we may have missed and where the field might want to go.
The importance of accurate clinical information in requests for radiological examinations: a comprehensive analysis
Authors: NELA Fluturim , HAXHI Sulejman
Published: October 2023

Introduction: Requests for radiological examinations are the first step in selecting patients to undergo radiological examinations. The range of radiological equipment, protocols, and examinations is very wide. Also, technological developments at very fast rates, as well as improvements in study protocols lead to innovations and updates in medical radiology. The starting point of this literature review study is our personal clinical experience, where we have often encountered requests for radiological examinations formulated without minimal clinical information. Purpose: This paper highlights the multifaceted benefits of having ample clinical information in order to select an optimal, widely accepted, and most importantly effective protocol to achieve the required imaging diagnosis. It is also of great importance for clinicians of various fields that their recommendations for radiological examinations can give the expected answers so that imaging diagnosis together with clinical and laboratory data reach an accurate diagnosis and optimal treatment for the patient. Methods: The selected sources were critically evaluated for their relevance and reliability in order to provide a complete perspective on the subject. The literature was selected on PUBMED and Medline. Results: From the several study groups that were engaged in finding data we found out that clinical information improved the accuracy of interpretation, clinical relevance, and confidence of reporting; however, reporting time was not substantially affected by the addition of clinical information. Conclusions: The findings of this literature review suggest that clinical information has a very positive impact on the correct selection of the examining protocol, on patient management, and most importantly on radiological reporting. It is in the best interest of radiologists and technicians to communicate the importance of clinical information as a very efficient tool for reporting examinations and to respond to radiological examination requests of referring clinicians as rigorously as possible. Further work is recommended to establish standards so that the requirements criteria for radiological examinations are specific, clear, and well-orientated across the wide range of examination techniques found in the diagnostic field.
“Midsommar”: Unraveling the impact of early-life trauma through art
Authors: PJETRUSHAJ Sara , MELONASHI Erika
Published: October 2023

The concept of “Trauma” is very popular, even among those who are unfamiliar with most psychological concepts. Although definitions may vary, the term usually refers to an experience or event, that causes distress on the person, to the point that it impacts their ability to cope and function, and can also cause intense psychological and emotional reactions, affecting their wellbeing (APA,2013). Trauma, including one-time events, but not limited to, not only leaves long lasting and repetitive effects on the survivor, but also affects everyone differently. According to the nature and type of trauma, and how it correlates with the personality of the individual who has experienced it, the way those effects manifest can be obvious, and can clearly impact cognitive functioning, in a way that we can clearly measure and diagnose it as Post Traumatic Stress Disorder (PTSD). However, trauma, might also be subtle and quiet, in cases where the symptoms do not specifically fall under the diagnostic criteria checklist, since these effects might be insidious, can be easily overlooked and, in turn, become destructive for the individual experiencing them (SAMHSA, 2014). The immediate reactions following the traumatic event are usually quite complicated and are shaped by the survivors’ personal experiences, their ability to.
Narratives of Albanian female offenders who killed their intimate partners during 2010-2014. Case report series
Authors: LAMA Voltisa , VISHA Ortenca
Published: October 2023

Introduction: Most homicide perpetrators in Albania (according to data from Tirana Central Prison Directory, 2015) were males (n=1170) and only 20 were females. Intimate partner homicides comprise the largest category of female-perpetrated homicide, 8 out of 20 female offenders were convicted because of intimate partner homicide. Aims: The present study examined the life experiences of Albanian women, who are serving prison sentences for killing their male intimates between 2010 and 2014. “We are here due to a damned minute!” said one of the women blaming the triggering event. Several psychosocial factors that are hidden can interact in the chain of events that may extend back from a triggering event to long-term processes that began in their childhood. These case studies shed light on those direct or indirect factors contributing to the murder. Method: On July 2015 the convicted women responded to open-ended interview questions, providing narrative accounts of their personal experiences from childhood to the act of killing. Questions were related to childhood experiences, relations and possible support from their biological family, possible traumatic events, relations to former partners, family dynamics with the murdered partner and children, attitudes toward their duties in the family and children’s responsibilities, insight for the causes of murder, social systems they looked for help, their feelings, circumstances and motivational contexts of intimate homicide, as well as regret. Results: Our in-depth interviews revealed that there was a similar profile of female homicide offenders who killed their intimate partners: they were grown up in harsh psychosocial circumstances during their childhood, most of them having some type of trauma, economically disadvantaged families, victims of abuse, undereducated, with limited opportunities and unemployed in the long-term prior to being incarcerated. The findings suggest that those psychosocial factors have played a role in the commitment of the crime.
Hetven éve szervezték újra az egységes vízügyi szolgálatot : A Nyíregyházi Vízügyi Igazgatóság 1953. évi megalakulásának előzményei és kezdetei
Authors: Konecsny Károly
Published: October 2023

A II. világháború utáni években a magyarországi vízügyi szervezetek a háborús rombolásokat követően csak nagy nehézségek között folytathatták szakmai munkájukat. Az államosítás és a vízügyi igazgatóságok megalakulása közötti évek (1948-1953) az ország politikai-társadalmi és gazdasági viszonyai tekintetében is igen nehéz időszakot jelentettek. Koncepciós eljárás indult több felső-tiszai vízügyi szervezet vezető szakemberei ellen, egyes társulati dolgozókat nem vettek át az állami szolgálatba kettétörve szakmai pályafutásukat, ellehetetlenítve megélhetésüket. Az államosítás után a Felső-Tisza-vidéki vízügyi szervezetek döntő része az Országos Vízgazdálkodási Hivatalnak (OVgH) alárendelt Debreceni Vízgazdálkodási Körzet, kisebb része a Miskolci Vízgazdálkodási Körzet alárendeltségébe került. A Debreceni Vízgazdálkodási Körzet keretében létrejött a Nyíregyházi Folyammérnöki Kirendeltség, a Nyíregyházi Ár- és Belvízvédelmi Kirendeltség és a Mátészalkai Ár- és Belvízvédelmi Kirendeltség. 1950. január 1-én kezdte meg önálló életét a Nyíregyházi Vízgazdálkodási Körzet, amelyet a nagyterületű debreceni körzetből választottak le. 1951. februárjától a Nyíregyházi Vízgazdálkodási Körzet átszervezése nyomán Nyíregyházi Árvízvédelmi és Folyamszabályozási Hivatal, valamint Nyíregyházi Kultúrmérnöki és Belvízrendező Hivatal létesült. A vízügyi szolgálat feldaraboltságát megszüntetve, 1953. október 1-én hozták létre az Országos Vízügyi Főigazgatóságot és a területi vízügyi igazgatóságokat, köztük a Nyíregyházi Vízügyi Igazgatóságot. A közleményben bemutatjuk a fenti jogelőd intézmények és az igazgatóság szervezetét, szakember gárdáját.
Esemény alapú csapadék-lefolyás modellezés különböző típusú csapadékadatok használatával
Authors: Négyesi Klaudia , Nagy Eszter Dóra
Published: October 2023

Csapadék-lefolyás modellezés esetén elengedhetetlen, hogy a felhasznált bemenő adatok minősége megfelelő legyen, beleértve a csapadék adatokat is. Napjainkban számos forrásból érhetőek el adatok, azonban ezek minősége és kezelhetősége eltérő lehet. Jelen kutatás két céllal rendelkezik: elsődleges cél a különböző forrásokból származó, eltérő típusú csapadékadatok használatának vizsgálata csapadék-lefolyás modellezés során, közepes méretű vízgyűjtők esetén. A kutatás további célja egy ingyenesen elérhető talajfizikai paramétereket tartalmazó adatbázis alkalmazása és annak alkalmazhatóságának minősítése. A vízgyűjtőmodellt ArcGIS és HEC-GeoHMS programok, míg a csapadék-lefolyás modellt a HEC-HMS (Hydrologic Engineering Center - Hydrologic Modeling System) szoftver segítségével állítottuk elő, mely determinisztikus, esemény alapú és összevont paraméterű. A modellezett események a vizsgált területen 2009 és 2016 között bekövetkezett árhullámok, vízgyűjtőnként kilenc darab. A modellbe bekerülő csapadékadatok felszíni csapadékmérő állomásokról, reanalízis adatbázisból, illetve a NASA által szolgáltatott, ingyenesen elérhető, műholdas adatbázisból származnak. A modell kalibrálása és igazolása a lefolyási mennyiségekre, illetve az árhullámok alakjára és a tetőzések időpontjaira is megtörtént. A modelleredmények alapján részletesen összehasonlításra kerültek a vizsgált adatforrások. A kezelhetőség, a felbontás, a lefolyási hányadok szórása és a kalibrálhatósági szempontok alapján értékeltük a különböző csapadékadatok alkalmazhatóságát. Az eredmények összesítését követően látható, hogy a vizsgált szempontok súlyozása nélkül a NASA műholdas adatok bizonyulnak a legmegfelelőbbnek. Ugyancsak megállapítható, hogy a talajfizikai adatbázisból származó értékeket kalibrálni szükséges.
The Major Causes of Local Currency Depreciation in Somalia

Published: October 2023

This study dwelled on the major causes of currency depreciation in Somalia. The main purpose of the study was to investigate in detail the major causes of local currency depreciation in Somalia. The study used qualitative research method using descriptive research design to investigate the major causes of local currency depreciation in Somalia. The study employed documentary review data collection tool and collected the secondary data through thorough review of the articles and books related to the major causes of local currency depreciation in Somalia. The key findings of the study on the major causes of local currency depreciation in Somalia encompass: existence of large quantities of Somali shillings in the market; the fall in the revenue collection by the government in the last two years weakens the country’s local currency and causes its depreciation;  existing monetary problems that hinder the control of financial activities by business owners in Somalia by the central bank of Somalia and financial regulatory authority in Somalia; weak monetary control coupled with lack of effective monetary policy to regulate and control the amount of inflow and outflow of foreign currency by the financial authority in the government such as Central Bank of Somalia and ministry of finance of the Federal Republic of Somalia and lastly dollarization of the economy which has replaced local currency and depreciated it owing to the massive inflow of foreign currency inform of remittance without being monitor and controlled by the financial authority in the country. The study recommended that the Federal Government of Somalia should introduce new monetary policy to monitor, control and supervise financial activities in the country and the Federal Government of Somalia should implement financial reform that allow the use of local currency to carry out all local transactions in Somalia to enable the local currency to regain its value and reduce the increasing rate of local currency depreciation.

Importance Of Laser Process Parameters And Part Thickness In The Microstructure Formation Of A PBF-LB Processed WE43
Authors: Nilsson Åhman Hanna , Mellin Pelle , D’Elia Francesco , Persson Cecilia
Published: October 2023

Powder bed fusion – laser beam (PBF-LB) of Mg alloys has great potential, both for producing patient specific implants and lightweight structures. However, the relationship among PBF-LB parameters, microstructure, and resulting material properties is poorly understood. As a first step towards a better understanding, the effect of various process conditions on the melt pool geometry and the microstructure formed is herein investigated. From the results it can be concluded that a lower scanning speed or a higher power result in deeper melt pools and more dendritic grains due to a warmer process. Similarly, thinner wall thickness also resulted in dendritic grains. A change in laser scanning line rotation between each layer showed that the grains tend to grow within the melt pool, rather than across several layers as seen for other alloys. These results show the importance of the parameters studied, and future work should investigate the resulting material properties.

Moreover, novel investigations have proven that Mg-alloys can be successfully processed by binder based sintering technologies like MIM and Fused Granular Fabrication (FGF). While MIM intends to near net shape mass production, the latter one applies mainly to prototyping and production of individual patient specific implants; even with a scaffold-like strut structure inside of a dense shell. This study compares mechanical properties and microstructures of the binary alloy Mg-6.3Gd, processed by MIM and by FGF, respectively. It is shown that today’s FGF technique achieves mechanical properties up to 217 MPa ultimate tensile strength (UTS) at 13 % elongation at fracture, comparable to the MIM processed reference material. Both processes, MIM and FGF lead to almost the same microstructure. Hence, novel FGF technique could overcome current challenges in 3D-printing of Mg-alloys.

In a first part of this study 13 commercial cermet grades for use in saw blades were characterised with respect to hardness, fracture toughness, microstructure, grain size distribution, and a full chemical analysis was employed. Subsequently, various Ti(C,N) cermet grades of similar composition were prepared by a conventional powder-metallurgical route. For each of these laboratory grades the starting powder formulation was varied with respect to grain size and alloy status of the hard phases while keeping the overall starting composition identical. In addition, different sintering atmospheres were applied which influenced the mechanical properties and alloy status of the binder. The influence of sintering atmosphere, powder type and alloy status, and carbon doping on hardness, fracture toughness and concentration of dissolved elements in the binder is discussed. A broad range of properties was achieved with the identical overall starting composition but different hard-phase powders and sintering conditions. With some laboratory grades close agreement with properties of industrial grades could be achieved.

PLANETARY NEBULAE
Authors: Eliwa Shahd
Published: October 2023

This project compares two planetary nebulae (NGC 1514 and NGC 40) and studies the difference between them in their chemical composition. Observations of the two planetary nebulae were done at Clanfield Observatory with the 24-inch Ritchey-Chrétien telescope. This project found that both planetary nebulae have a similar nebula spectrum but a different central star spectrum. The NGC 1514 central star is a type ‘DA white dwarf’. While the NGC 40 central star is a type ‘DQ white dwarf’. The different classes of white dwarfs could be a result of AGB thermal pulsations or superwind phases.
