Proposal of a Technique for Correlating Defect Dimensions to Vibration Amplitude in Bearing Monitoring
Authors: Brusa Eugenio , Bruzzone Fabio , Delprete Cristiana , Di Maggio Luigi , Rosso Carlo 
Published: March 2024

The capability of early stage detection of a defect is gaining more and more importance because it can help the maintenance process, the cost reduction and the reliability of the systems.
The increment of vibration amplitude is a well-known method for evaluating the damage of a component, but it is sometimes difficult to understand the exact level of damage. In other words, the amplitude of vibration cannot be directly connected to the dimension of the defect.
In the present paper, based on a non-Hertzian contact algorithm, the spectrum of the pressure distribution in the contact surface between the race and the rolling element is evaluated. Such spectrum is then compared with the acquired spectrum of a vibration response of a defected bearing. The bearing vibration pattern was previously analyzed with monitoring techniques to extract all the damage information.
The correlation between the spectrum of the pressure distribution in the defected contact surface and the analyzed spectrum of the damaged bearing highlights a strict relationship. By using that analysis, a precise correlation between defect aspect and dimension and vibration level can be addressed to estimate the level of damaging.
On the use of PCA for Diagnostics via Novelty Detection: interpretation, practical application notes and recommendation for use

Published: March 2024

The Principal Component Analysis (PCA) is the simplest eigenvector-based multivariate data analysis tool and dates back to 1901 when Karl Pearson proposed it as a way for finding the best fitting d-1 hyperplane of a system of points in a d-dimensional (Euclidean) space.
Over the time, the PCA evolved in different fields with several different names and with different scopes, but, in its essence, it is always an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components.
Generalizing Pearson’s purpose, the knowledge derived by such an analysis is mostly used to find a subspace which effectively and efficiently summarizes the original system of points by losing a minimum amount of information.
In the field of Diagnostics, the fundamental task of detecting damage is basically a binary classification problem which is in many cases tackled via Novelty Detection: an observation is classified as novel if it differs significantly from other observations. Novelty can, in principle, be assessed directly in the original space, but the effectiveness of the estimated novelty can be improved by taking advantage of the PCA.
In this work, the traditional PCA will be compared to a robust modification that is commonly used in the field of diagnostics to face the issue of confounding influences which could affect the novelty-damage correspondence. Comparisons will be made to shed light on the main misleading aspects of PCA, and finally, define a unique, theoretically justified procedure for Diagnostics via Novelty Detection.
Model-based Prognosis Approach using a Zonotopic Kalman Filter with Application to a Wind Turbine
Authors: Khoury Boutros , Puig Vicenç , Nejjari Fatiha 
Published: March 2024

Wind turbines generally operate under adverse conditions making them prone to relatively high failure rates. Due to the direct exposure of the blades to dynamic and cyclic loads of wind, the rotor and the blades unsurprisingly represent the most common major component damages of a wind turbine system, which is especially enhanced when located offshore.
This paper presents a new model-based prognosis procedure based on a zonotopic Kalman filter (ZKF), which combines a physical model with observed data to assess the system degradation. Using this information and the model of the system, the end of life (EOL) and the remaining useful life (RUL) with its uncertainty can be predicted. The proposed prognostic method is applied to monitor the state of health of a wind turbine system specifically, its blades. The remaining useful life prediction will help in scheduling optimal maintenance and reducing the cost caused by wind turbine damage and unplanned shutdown.

Study on the Manufacturability of X Dimension Fan Out Integration Package with Organic RDLs (XDFOI-O)
Authors: Chen Haijie , Bian Ziyao , Liu Tao , Xie Jielei , Wu Jingyu , Lin Yaojian , Lee Choon Heung 
Published: March 2024

The concept of chiplet was proposed in the post- Moore era. How to layout the multiple chips with different processes and sizes in the package structure is a problem that needs to be considered as different layouts may significantly affect the manufacturability during the packaging process. XDFOI-O is a 2.5D organic interposer structure with a significant coefficient of thermal expansion mismatch in it. Different layouts may cause excessive stress concentration in the package structure, as well as large wafer warpage, which can affect the normal operations of the production line. Stress accumulation on specific chiplet during the wafer thinning process is another manufacturability problem, leading to chip cracking. Prospective finite element analysis can be applied to evaluate the various layouts. In simulation work, different placement processes of dummy chips as stiffeners, as well as different chiplet thicknesses and underfill coverage, can be used as factors for simulation studies, thereby making a reference for further chiplet package design.
Transforming WLP Applications: Introducing Cutting-Edge Next-Generation Nanotwinned Copper Processes to Revolutionize Hybrid Bonding

Published: March 2024

We discuss two electrochemical plating approaches for nanotwinned copper (ECP nt-Cu)—Gen 1 and Gen 2. These two approaches allow control over columnar width and transition layer thickness on Cu substrates, enabling the filling of nanotwinned Cu for bonding applications. Both approaches produce stable nt-Cu structures with minimal transition layers when electroplated on (111) Cu substrate. However, grain size, transition layer thickness on polycrystalline substrates, and feature-filling behavior differ. The researchers suggest that the choice between Gen 1 and Gen 2 depends on the feature size, aspect ratio, and applications. In addition, further exploration into other additives improves bottom-up filling capabilities, enabling more versatility for applications. Both approaches enable the filling of nanotwinned Cu inside bottom-seeded and complete-seeded features, with 100% nanotwin growth parallel to the substrate for bottomseeded features. However, nanotwin growth percentage and direction depend on feature size and aspect ratio for complete-seeded features. Gen 2 tends to have less sidewall growth due to its smaller grain size and is more compatible with other additives, making it promising for high aspect ratio small features.

Uvod. Pertusis, poznat i kao veliki kašalj, je akutna zarazna respiratorna bolest koju izaziva bakterija Bordetella pertussis. To je jedina vakcinom preventabilna bolest koja beleži porast obolelih u svetu i pored visokog obuhvata dece vakcinacijom. Bolest se prenosi kapljičnim putem, a klinički simptomi variraju od uzrasta. Najugroženija su novorođenčad i odojčad mlađa od dva meseca, koja zbog uzrasta ne mogu biti vakcinisana. Pravovremena imunizacija vakcinom uz obuhvat od 95% populacije je najefikasnija mera zaštite protiv pertusisa. Prema podacima Instituta za javno zdravlje Srbije "Dr Milan Jovanović Batut", u Srbiji je tokom 2023. godine zabeleženo 909 slučajeva velikog kašlja.
Prikaz serije slučaja. Opisali smo seriju od sedam potvrđenih slučajeva pertusisa u primarnoj pedijatrijskoj praksi, tokom oktobra i novembra meseca 2023. Dvoje od sedmoro pacijenata su odojčad, od kojih je jedno nevakcinisano a drugo je dobilo samo jednu dozu iz primoserije petovalentne vakcine. Četvoro pacijenta su deca školskog uzrasta, redovno vakcinisana za uzrast, ali je kod njih od poslednje doze vakcine prošlo više od deset godina. Svi su imali simptome kašlja sa paroksizmima i postusivnim povraćanjem, a u nalazu krvne slike bila im je prisutna leukocitoza sa dominantnom limfocitozom. Kod petoro je postavljena dijagnoza PCR dijagnostikom, a kod dvoje pacijenata serološkim analizama. Dvoje nevakcinisane i nepotpuno vakcinisane odojčadi zahtevalo je hopitalizaciju. Kod svih pacijenta je došlo do postepene i potpune regresije simptoma tokom 6 nedelja.
Zaključak. Veliki kašalj nije zaboravljena bolest. Prevencija, rano otkrivanje i prepoznavanje obolelih kao izvora infekcije su od suštinskog značaju u suzbijanju epidemije pertusisa.

<p>The study analyzes the relationship between technology and economic growth in Sierra Leone from 2011 to 2022 and the data are treated via the E-Views program. ARDL methodology was used. The results showed a co-integration relationship between the study variables (computer use in general; computer use at work; and computer use in education, training, and economic growth) and the results presented that the deviation from long-term equilibrium is corrected using an error correction model which long term corrected as a percentage correction (−0.06) each year from the short term to the long term and showed the results of the structural stability test of the (ARDL) model. It is a structural stability test for long and short-term coefficients, which showed that the data used in this study are free from any structural changes but has stable parameters over time. The study also used CUSUM's Squares test, where the test results showed that the study model used is economically good and can be relied upon to anticipate economic solutions in Sierra Leone according to the situation in the coming years, and among the most important recommendations of the study are the following: the need to encourage the use of technology in work, education, and training, and the need for expansion in using these technological means as a gateway to the digital economy and the digital state.</p><p><strong> </strong></p><p><strong>JEL</strong>: O33, O47, C51, C22, O14, O55</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0708/a.php" alt="Hit counter" /></p>
MAKING COMPLAINTS IN GHANAIAN ENGLISH: AN ANALYSIS OF SENIOR HIGH SCHOOL STUDENTS
Authors: Lomotey Charlotte Fofo , Sam Barbara Bosomtwe 
Published: March 2024

Complaints are bound to occur in our daily interactions while seeking a remedy to that which has directly or indirectly affected someone unfavourably, thus, threatening the face of the addressee and may eventually engender social relationship breakdown if not done appropriately. This study examined complaints by speakers of Ghanaian English in three public second cycle schools in Ghana to ascertain the politeness strategies invested in expressing their dissatisfaction with an unacceptable act in Ghanaian English. The Brown and Levinson (1987) politeness theory served as the theoretical framework for the study. A case study design was adopted with data elicited from ninety-four (94) participants role-playing four complaint-provoking situations and analysed thematically. The findings revealed that eleven strategies are used in producing different complaints in Ghanaian English. The findings further indicated that Ghanaians are indirect and tend to have a high inclination toward positive politeness strategies as they try to reduce the effect of the face-threatening act of complaining on the addressee’s positive face. It was also found that this complaint behaviour is influenced by the cultural norms of politeness in Ghanaian languages.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0662/a.php" alt="Hit counter" /></p>
