A System for Personality and Happiness Detection

This work proposes a platform for estimating personality and happiness. Starting from Eysenck's theory about human's personality, authors seek to provide a platform for collecting text messages from social media (Whatsapp), and classifying them into different personality categories. Although there is not a clear link between personality features and happiness, some correlations between them could be found in the future. In this work, we describe the platform developed, and as a proof of concept, we have used different sources of messages to see if common machine learning algorithms can be used for classifying different personality features and happiness

Longitudinal Segmented Analysis of Internet Usage and Well-Being Among Older Adults

The connection between digital literacy and the three core dimensions of psychological well-being is not yet well understood, and the evidence is controversial. We analyzed a sample of 2,314 individuals, aged 50 years and older, that participated in the English Longitudinal Study of Aging. Participants were clustered according to drivers of psychological well-being using Self-Organizing Maps. The resulting groups were subsequently studied separately using generalized estimating equations fitted on 2-year lagged repeated measures using three scales to capture the dimensions of well-being and Markov models. The clustering analysis suggested the existence of four different groups of participants. Statistical models found differences in the connection between internet use and psychological well-being depending on the group. The Markov models showed a clear association between internet use and the potential for transition among groups of the population characterized, among other things, by higher levels of psychological well-being

"The Recovering Community" and the power of choice

Die vorliegende Arbeit beschäftigt sich mit der sogenannten "Recovering Community". Diese soziale Gruppe ist als ein solidarischer Zusammenschluss von Menschen zu definieren, die versuchen, sich von verschiedenen Abhängigkeiten, zwanghaften Handlungsmustern und anderen kategorisierten Zwängen zu befreien (z.B.: Gruppe der Anonymen Alkoholiker). Dies versuchen sie mittels einer Philosophie bzw. eines „spirituellen Programms“ umzusetzen, das sich „The Twelve Steps“ nennt. Verschiedene Studien zu Abhängigkeiten und deren Überwindung empfehlen bis heute die Anwendung des „12-Stufen-Programms“ als eine der effektivsten Methoden, um „substantielle Abhängigkeiten“ zu bekämpfen. Damit verknüpft ist auch die Fragestellung nach den Definitionen von „Abhängigkeit“ und „Sucht“ selbst. Vor allem konsumanthropologische Perspektiven helfen, die „Recovering Community“ und ihre gesellschaftlichen Funktionsweisen zu analysieren und zu diskutieren: Gruppen, die sich unter Bezugnahme auf das 12-Stufen-Modell formieren und deren Handlungsweisen sind Ausdruck eines „modernen“ Lebensstils und in Zusammenhang mit dem ökonomischen Begriff der „Rationalität“ zu diskutieren. Sie sind, sozial als auch ökonomisch, Teil der „westlich“- urbanen Welt. Besonderes Augenmerk wird dabei auf die Verschränkung der Analyse mit Thema „Konsumption“ gelegt. Die interkulturelle Perspektive auf die „Recovering Community“ und ihre Gruppenmitglieder ermöglicht es, Betrachtungweisen von materiellen Anhängigkeiten zu erweitern und neue, zusätzliche Aspekte in die Diskussion einzubringen (Relativität von Bedürfnissen, Dekonstruktion westliche determinierter Werte, etc.). Die „Recovering Community“ wird als Teil von westlich-moderner Lebensweise analysiert und dem Phänomen des Massenkonsums gegenübergestellt. Dabei wird es möglich, die Beziehung der Betroffenen zu ihren Zwängen und Abhängigkeiten zu analysieren und besser zu verstehen. Die „Recovering Community“ wird somit als Teil gelebter, gesellschaftlich determinierter Konsumpraktiken begriffen.The Recovering Community (as the social group matter of our thesis refers to itself), is a fraternity of people who are "recovering" from a variety of compulsive behaviors, chemical dependencies, and other differently cathegorized issues, through the practice of a "spiritual program" and a philosophy called the twelve-steps. There are various empirical studies that suggest that, up to this moment, the twelve-steps are "the most effective treatment for the condition of 'chemical dependency". However, within the academic realm of psychology and addiction studies, both the reasons why the steps "work" and the definition of addiction itself, are subject to debate. Since the phenomena of recovery groups initially seems to be related to mass-consumption societies, I will use anthropology to step away from the boundaries of context that burdens other disciplines who study "addiction" and the recovering community, and will approach these studies from a different angle. We will study both the "recovering community" and "addiction" within the context of "modernity" and mass-consumption as opposed to from these contexts. By doing so we are able to analyze the relationship that our subjects of study and their "afflictions" hold with the mentioned contexts. As we will find out, a great deal of light is shed following this path regarding the recovering community, but more light is shed concerning the consumption patterns of what has been named by many as "consumerism"

A graphical user interface for PCA-based MSPC: A benchmark software for multivariate statistical process control in MATLAB

[EN] A Graphical User Interface (GUI) is developed in MATLAB as a tutorial for understanding the PCA-based MSPC strategy. The software allows users to analyze both simulated and external data sets. Simulated data are obtained from a nonlinear model of a binary distillation column implemented in Simulink. The nonlinear model has four manipulated variables, four controlled variables and three input measured disturbances, plus 41 M fractions corresponding to every column stage. The methodology for PCA-based MSPC is implemented in two phases. During Phase I, the user can simulate the distillation column under normal operating conditions at three different operating points. When the simulation is finished, the GUI obtains the corresponding PCA model automatically. In Phase II, the user can simulate several scenarios with different combinations of disturbances and failures and monitor them using Squared Prediction Error (SPE) and T-2 control charts. Contribution plots are used to diagnose the original variables responsible of such abnormal situations. The software also incorporates the possibility to analyze external multivariate process datasets.Research in this study was partially supported by the Spanish Ministry of Economy, Industry and Competitiveness under the grant DPI2017-82896-C2-1-R.Villalba-Torán, PM.; Sanchís Saez, J.; Ferrer, A.

Microstructural aspects of the transition between two regimes in orthogonal cutting of AISI 1045 steel

In depth understanding of tool-chip friction behavior is a significant aspect for tool wear performance in steels. In the present work attention has been paid to the strain mode of the chip section in contact with the rake surface of the tool, and its influence on the mechanics of material removal. There is a multitude of evidence for the existence of qualitatively different cutting regimes in orthogonal machining of annealed AISI-1045 steel with uncoated P15 carbide cutting tools in dry conditions at cutting speeds between 5 and 200 m/min. The evaluation of chip morphology and microstructure, and cutting and feed forces, revealed an abrupt step-like transition at a cutting speed in the range of 50–60 m/min, which was attributed to the transition from built-up edge (BUE) mode developed at low cutting speed, to the mode at which the chip slides directly over the tool surface. These qualitatively distinct mechanisms of tool-chip interaction are determined by two different microstructural effects: work hardening by severe plastic deformation and microstructural softening by dynamic recrystallization (DRX). It is argued that the onset of DRX is the reason for further instability of BUE and thus is the main cause of change of the cutting regime

Experimental investigation of contact forces and temperatures in rubbing interactions of honeycomb interstate seals

The new architecture of high velocity aircraft engines includes labyrinth-honeycomb interstate seals to improve the engine’s stability. To increase these engines capacity a commonly used strategy is to reduce the clearance between the blades and the sealing system. However, this reduction causes non-desired contacts (rubbing) between the rotating and static components of the engine. This rubbing interaction has an adverse effect on the engine life (wear and thermal cracking) and efficiency. In this work, experimental tests were carried out to recreate the rub between an F110 steel fin and a Hastelloy X honeycomb seal. A conventional CNC machine controlled the sliding and penetration velocities, and the interaction forces and fin tip temperatures were measured during the rub. Results demonstrate the dependence that both, interaction forces and tip temperatures, have with sliding and penetration velocities. However, it is clear that this influence is more pronounced in relation to the sliding velocity

Mechanical properties of friction induced nanocrystalline pearlitic steel

Nanocrystalline structured variants of commercially available alloys have shown potential for boosting the mechanical properties of these materials, leading to a reduction in waste and thereby retaining feasible supply chains. One approach towards achieving these nanostructures resides in frictional treatments on manufactured parts, leading to differential refinement of the surface structure as compared to the bulk material. In this work the machining method is considered to be a testing platform for the formation and study of frictional nanostructured steel, assembly of which is stabilized by fast cooling of the produced chip. Analysis of the mechanical properties has shown extraordinary results at the surface, over 2000 MPa of strength on AISI1045 steel, more than three times the strength of the base material, demonstrating at the same time a reduction of 15% in the elastic modulus. The microscopic analysis suggests a reassembly of the elements in a new lattice of carbon supersaturated nano-ferrite
