A Model for Drying Control Co-Solvent Selection for Spin Coating Uniformity: The Thin Film Limit
Creators: name: Birnie, Dunbar
Publisher: name: Rutgers University
Year: 2013
Subjects: Coatings
Spin coating
Marangoni effect
Striation defects
Solvent evaporation
Thin Films

description: Striation defects in spin-coated thin films are a result of unfavorable capillary forces that develop due to the physical processes commonly involved in the spin-coating technique. Solvent evaporation during spinning causes slight compositional changes in the coating during drying, and these changes lead to instability in the surface tension and this causes lateral motions of the drying fluid up to the point where it gels and freezes-in the thickness variations. In an earlier publication we looked at the case where evaporation happens fast enough that the compositional depletion is mostly a surface effect. In terms of the mass transport rate competition within the coating solution then that work covered the thick-film limit of this instability problem. However, in many cases the coatings are thin enough or diffusion of solvent within the coating is fast enough to require a different solvent mixing strategy, which is developed here. A simple perturbation analysis of surface roughness is developed and evaporation is allowed in the thin film limit. The perturbation analysis allows for a simple rubric to be laid out for co-solvent additions that can reduce the Marangoni effect during the later stages of coating deposition and drying when the thin-film limit applies.

A  comparative evaluation of some measures of skewness
Creators: name: Amodeo, E.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: In this paper some rigorous definitions of  left (right) skewness, of regular left (right) skewness and of comparison between "simply" skew distributions (strong comparison), and between regular distributions (strog comparison) are reviewed with reference to Frosini (1984). This to judge the coherence of the measures of skewness to be discussed.
Six main indices of skewness are examined. The coherence— in general—of an index proposed by Bonferroni (A1) and of an index proposed by Gini (A2) is shown; moreover the validity of the index A3 introduced by Frosini, in the set of regular skew random variables, is recalled. The other indices studied are: the difference between the mean and the median related to the standard deviation (A4); the difference between the mean and the mode related to the standard deviation (A5); the ratio between the third central moment and the cube of the standard deviation.
The behaviour of these indices is considered with reference to six groups of comparable —and not—skew distributions; thus we have been able to verify the coherence and to point out some unexpected features of the indices; the results prove the invalidity of A4 and A5. Besides, the comparison between the most important graphs of the indices is confirmed by the correlation coefficients computed for couples of indices, for each group of distributions.

Database Server Organization for Handling Mobile Clients

description: The use of mobile computers is gaining popularity. The number of users with laptops, notebooks is increasing and this trend is likely to continue in to the future where the number of mobile clients will far exceed the number of traditional fixed" clients. Applications running on the mobile clients download information by periodically connecting to repositories of data stored in either databases or file systems. Such mobile clients constitute a new and different kind of work load and exhibit a different access pattern than seen in traditional client server systems. Though file systems have been modified to handle clients that can download information, disconnect, and later reintegrate, databases have not been redesigned to accommodate mobile clients. There is a need to support mobile clients in the context of client server databases This paper is about organizing the database server to take into consideration the access patterns of mobile clients. We propose a concept of hoard key which captures these access patterns. Three different techniques for organizing data at the server based on the hoard key are presented. We argue that each technique is suited for a particular workload. The workload is a combination of requests from mobile clients and traditional clients. This reorganization also allows us to address issues of concurrency control, disconnection, replica control in mobile databases. We present simulation results that show the performance of server reorganization using hoard keys. We also provide an elaborate discussion of issues resulting from this new reorganization in this new paradigm that includes mobile clients and traditional clients.

description: We have investigated the gravity-driven transport of spherical colloids suspended in the nematic liquid crystal 4-cyano-4′-pentylbiphenyl (5CB) within microfluidic arrays of cylindrical obstacles arranged in a square lattice. Homeotropic anchoring at the surfaces of the obstacles created periodic director-field patterns that strongly influenced the motion of the colloids, whose surfaces had planar anchoring. When the gravitational force was oriented parallel to a principal axis of the lattice, the particles moved along channels between columns of obstacles and displayed pronounced modulations in their velocity. Quantitative analysis indicates that this modulation resulted from a combination of a spatially varying effective drag viscosity and elastic interactions engendered by the periodic director field. The interactions differed qualitatively from a sum of pair-wise interactions between the colloids and isolated obstacles, reflecting the distinct nematic environment created by confinement within the array. As the angle α between the gravitational force and principal axis of the lattice was varied, the velocity did not follow the force but instead locked into a discrete set of directions commensurate with the lattice. The transitions between these directions occurred at values of α that were different from those observed when the spheres were in an isotropic liquid, indicating the ability of the liquid crystal forces to tune the lateral displacement behavior in such devices.

The promise of Andean khipu transcriptions : a multi-scale investigation

description: Among the most distinctive documents from the early-colonial Andes are Spanish-language transcriptions of information rendered, in various settings, from khipus—undeciphered knotted string devices that served the function of writing in the Inka Empire (c. 1400–1532 CE). The surviving khipu transcriptions, sometimes also referred to as “paper khipus,” have informed decades of historical research and decipherment projects, which in large part have foregrounded the close study of individual transcriptions. However, how might the conclusions reached from these documents evolve when they are instead studied from a variety of distances and interpretive vantage points—close and far; qualitative and quantitative? Informed by currents in performance theory, semiotics, and the digital humanities, this thesis presents close reading and quantitative aggregation as mutually reinforcing strategies for the study of early colonial khipu transcriptions, employing what Ted Underwood has called a “juxtaposition of scales.” It is argued, by way of three practical case studies, that a multi-scale approach to studying paper khipus enables as much the revelation of new ethnohistoric insights as it does the assessment of previous hypotheses derived from close reading. Following a historical introduction to khipus and their colonial-era transcriptions, the first case study finds that scribal corrections in a handful of paper khipus may preserve traces of the original “readings” of knotted strings by Andean cord keepers. The second case study zooms out to analyse action verb usage across 10,000 lines of digitized khipu transcriptions, adding new contours to previous narratives of early-colonial economic transformation first proposed by scholars including John Murra and others. Finally, the third case study presents a blueprint for the ambitious task of searching for matches between the surviving transcriptions and individual khipus in existing collections, focusing on a khipu studied by the author in the Museum der Kulturen (Museum of Cultures), Basel, Switzerland. The multi-scale approach is discussed throughout as a tool for ethnohistorians investigating other records of cross-cultural encounter.
On the role of the Kummer distribution as a prior for attributes sampling

description: L'A. si propone di evidenziare come la cosiddetta funzione di densità (d.f.) del Kummer consegua, quale a priori per un processo bernoulliano, da differenti approcci che un ricercatore può seguire nell'assegnare un a priori sulla frazione p dei difettosi di un processo produttivo. A tal fine egli dapprima esamina ruolo e caratteristiche di alcuni prodotti ponderati normalizzati delle funzioni di densità più comunemente utilizzate quali a priori nell'ambito del controllo statistico della qualità.Quindi egli mostra che la procedura del prodotto ponderato porta alla distribuzione del Kummer quando è impiegata come criterio di aggregazione statistica di talune semplici funzioni di densità a priori specificate sulla base di probabilità assegnate da due esperti, uno dei quali è consultato in termini della fusione dei difettosi e l'altro in termini di quella dei non difettosi. L'A. passa poi a rilevare che la distribuzione del Kummer si profila anche quando può ritenersi ragionevole configurare il processo di assegnamento del manager articolato in due fasi consecutive, nella prima delle quali si accoglie come a priori una semplice funzione di densità vista come congettura di primo approccio, mentre nella seconda il processo di lavorazione è inteso come un processo bernoulliano. L'A. dà infine un esempio col solo scopo di illustrare anche un criterio di assegnazione di valori ai parametri della distribuzione del Kummer.

Problems and methods in evaluating the reliability of national accounts
Creators: name: Trivellato, U.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The reliability of national accounts depends on a great variety of data sources and estimating techniques. The article focuses on some major methodological problems in assessing national accounts reliability. It is argued that the combined use of data of varying quality, and the additional operations of aggregation, estimation and adjustment, make the assessment of overall reliability almost impossible. The inquiry provides a framework for reliability analysis based on partial criteria suitable for measuring the main aspects of reliability. The following criteria are presented and critically discussed (a) subjective reliability ratings, assigned by experts; (b) consistency criteria, that measure the discrepancy between two or more values of the same economic aggregate (typical cases are the sratistical discrepancy between the expenditure and production approaches to GDP, or GNP, and the periodic revisions of preliminary estimates); (c) accuracy criteria, that involve an evaluation of the observed values with reference to the 'true' values. The emphasis is on the specification of appropriate measurement models, crucial to investigate the characteristics of errors.

On a method of estimating the expenditure elasticity from concentration curves
Creators: name: Dancelli, L.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: In 1960 N.S. Iyengar developed a new method of estimating the expenditure elasticity of a specific item from two concentration curves the Lorenz curve of total expenditure (or income) and a generalized Lorenz curve which relates the proportion of consumption of the specific item to the proportion of consumers spending up to a given level of the total expenditure. On the assumptions of log normality of total expenditure distribution and of constancy of elasticity, the author derived an expression for elasticity that is valid just for two particular points of the range of the concentration curves.
In this work we give a new expression for elasticity that can be calculated for any point of the range of the concentration curves. Iyengar's results follows as particular cases of it. Moreover, the two underlying hypotheses can be easily checked through this same expression.
A generalization of a concentration curve recently studied by M. Zenga is also considered giving rise to an equivalent formula for elasticity
Finally, a numerical illustration based on expenditure data in Italy shows the advantages of the new suggested approach compared to former results obtained by R. Guarini.

description: Background: Traits and characteristics qualitatively similar to those seen in diagnosed autism spectrum disorder can be found to varying degrees in the general population. To measure these traits and facilitate their use in autism research, several questionnaires have been developed that provide broad measures of autistic traits [e.g. Autism-Spectrum Quotient (AQ), Broad Autism Phenotype Questionnaire (BAPQ)]. However, since their development, our understanding of autism has grown considerably, and it is arguable that existing measures do not provide an ideal representation of the trait dimensions currently associated with autism. Our aim was to create a new measure of autistic traits that reflects our current understanding of autism, the Comprehensive Autism Trait Inventory (CATI). Methods: In Study 1, 107 pilot items were administered to 1119 individuals in the general population and exploratory factor analysis of responses used to create the 42-item CATI comprising six subscales: Social Interactions, Communication, Social Camouflage, Repetitive Behaviours, Cognitive Rigidity, and Sensory Sensitivity. In Study 2, the CATI was administered to 1068 new individuals and confirmatory factor analysis used to verify the factor structure. The AQ and BAPQ were administered to validate the CATI, and additional autistic participants were recruited to compare the predictive ability of the measures. In Study 3, to validate the CATI subscales, the CATI was administered to 195 new individuals along with existing valid measures qualitatively similar to each CATI subscale. Results: The CATI showed convergent validity at both the total-scale (r ≥ .79) and subscale level (r ≥ .68). The CATI also showed superior internal reliability for total-scale scores (α = .95) relative to the AQ (α = .90) and BAPQ (α = .94), consistently high reliability for subscales (α > .81), greater predictive ability for classifying autism (Youden’s Index = .62 vs .56–.59), and demonstrated measurement invariance for sex. Limitations: Analyses of predictive ability for classifying autism depended upon self-reported diagnosis or identification of autism. The autistic sample was not large enough to test measurement invariance of autism diagnosis. Conclusions: The CATI is a reliable and economical new measure that provides observations across a wide range of trait dimensions associated with autism, potentially precluding the need to administer multiple measures, and to our knowledge, the CATI is also the first broad measure of autistic traits to have dedicated subscales for social camouflage and sensory sensitivity.

Split smart messages: middleware for pervasive computing on smart phones
Creators: name: Ravi, Nishkam

Publisher: name: Rutgers University
Year: 2005

description: Smart Phone is a recently emerged technology that supports Java program execution and provides both short-range wireless connectivity (Bluetooth/IrDA) and Internet connectivity (GPRS/3G). Smart Phones represent the first viable ubiquitous computing devices because they are becoming an integral part of our daily life. Although these phones are closed systems with limited resources, we believe that a multitude of distributed applications in which Smart Phones act as peers in ad hoc networks can be developed. To realize the potential, there is a need for a middleware that supports such applications and a systematic study of the communication/ computation trade-offs. The middleware should provide functionality to support service execution, discovery and migration and should be able to score well on three criteria: portability, security, and performance. To achieve this goal, we have implemented and evaluated Split Smart Messages (SSM), a lightweight middleware architecture similar to mobile agents, that exploits dual connectivity on Smart Phones. Services can be executed, discovered, and migrated on top of the SSM middleware. To facilitate portability, we have designed an execution migration scheme that works on top of unmodified Java virtual machines. To improve upon security while preserving performance, code is uploaded to and downloaded from a trusted web server, while data and state are transferred across the local network. We have implemented an SSM prototype on Sony Ericsson P800/P900 Smart Phones and compared its performance with that achieved on HP iPAQ PDAs.
Birth weight within the sibships

Year: 2013

description: The reproductive histories of 1065 pluriparous women are collected by a match of the records of the deliveries at the hospital of Padua between the years 1963-77. This material is analysed in two stage. In the present note we study the variations of the birth weigh in the sibs; in a future one we will analyse the variations of the gestation length.
The variables utilized  are the following: difference of birth weigh between the sibs, difference of gestation length, difference of birth order, difference of age of the mother at the deliveries, difference of the  sex of the sibs. These variables are introduced in a multiple linear regression model of the birth weight. The partial regression coefficient relative to the birth order is positive. The frequency of the histories in which the weight of  successive  sibs increased are also examined. It results that this situation is not the most frequent but the histories  with an oscillating dynamics are the more numerous

Carbon emissions
Industry structural change
China
Linear Programming

description: This paper uses an optimal interregional input-output model to focus on how interregional industrial shifts alone might enable China to reduce carbon intensity instead of national shifts. The optimal industry shifts assure integration of all regions by regional services and goods in which carbon emissions are embodied via energy consumption. Generally speaking, high-tech industries should concentrate in affluent regions to replace construction. Selected services should increase output shares across most of regions. Meanwhile, energy-intensive manufacturing, rather than agriculture, should decrease their shares to achieve the national annual growth constrained by nation’s carbon targets. Due to the need to decelerate energy use, carbon intensity goal puts particularly extreme pressure on less-developed regions to shutter heavy industries. Explicit shifts toward cleaner resources and renewable energy appear to be quite important for keeping coal mines in Central China working.

description: In questo lavoro viene esaminato il problema dell'inferenza su una caratteristica osservabile in una popolazione finita subordinatamente alla conoscenza di una variabile ausiliaria categorica. Il punto di partenza è costituito da un semplice modello gerarchico analogo  a quello dell'analisi della varianza con effetti casualizzati. Sulla base di tale modello viena rilevata  una distribuzione a posteriori subordinata per la parte non campionata della popolazione e per la media globale. Ricevono particolare attenzione le varie ipotesi di indipendenza subordinata utilizzate a livelli diversi nel procedimento inferenziale. Viene impiegata una notazione matriciale che contribuisce a tenere conto della ripartizione della popolazione nella parte campionata ed in quella non campionata.

Highest utility first search: a control method for multi-level stochastic design

Publisher: name: Rutgers University
Year: 1998

description: An intrinsic characteristic of stochastic optimization methods, such as simulated annealing, genetic algorithms and multi-start hill climbing, is that they can be run again and again on the same inputs, each time potentially producing a different answer. When such algorithms are used in a design process with multiple levels of abstraction, where the output of one stochastic optimizer becomes the problem statement for another stochastic optimizer, we get an implicit tree of alternative designs. After each optimizer run we face a control problem of which level's optimizer to run next, and which design alternative to run it on. This problem is made more difficult by the fact that we generally can get a precise evaluation of the design alternatives only at the lowest level (the final results), and must make do at higher levels with only an estimate of how good a final design each alternative will lead to.

Approximate structured optimization by cyclic block-coordinate descent
Creators: name: Villavicencio, Jorge

Publisher: name: Rutgers University
Year: 1995

description: A uniform randomized exponential-potential block-coordinate descent method for the approximate solution of block-angular convex resource-sharing programs was analyzed in [5] and for the linear case in [14]. The former method is rendered deterministic by replacing its random block selection by arbitrary sweeps of its block coordinates, akin to classical implementations of Gauss-Seidel relaxation and coordinate descent in unconstrained optimization, recently used in concurrent network flows [15]. The general block-angular model consists of K disjoint convex compact sets ("blocks") and M nonnegative convex block-separable inequalities (coupling constraints"). It is shown that for linear coupling constraints and for a given but arbitrary relative accuracy " 2 (0; 1], the proposed derandomized algorithm runs in O(K lnM("2 + ln minfK; Mg) coordination steps or block optimizations, which is lower than all other existing bounds. It is also shown that this bound on coordination steps also applies to a reformulation of the above general nonlinear problem.

We examine the Kullback-Liebler divergence, which has been widely applied to classify time series with respect to the dominant frequency bands. Moreover, we analyse the connections between that approach based on the comparison of spectral densities and the alternative form in terms of the parameters or ARMA models. Finally, the relations between the J-divergence and other discrimination measures are discussed.

description: Youth unemployment problem is studied with duration models in the framework of the "survival analysis". The time spent searching a job is then modelled with countinuous-time stochastic processes for event history data.  At first, a single spell duration model is formulated and estimated for identifying the major variables affecting the probability of getting a job. Then the processes is generalized and a multi-state and multi-episode model is proposed for analysing the dynamics between the states of unemployment, temporary employment and permanent employment. The empirical study is performed on a body of longitudinal data  collected in retrospective interviews of a sample of Italian young people and provided by "ISFOL".

description: Quando i prezzi dei prodotti e dei fattori sono generati da un processo aleatorio, gli agenti economici devono formulare le loro personali aspettative al riguardo e devono fare i necessari aggiustamenti delle quantità. Il presente lavoro introduce tali aspettative e aggiustamenti nei modelli di programmazione matematica e ne indica l'uso per studiare problemi di politica dei prezzi. Il problema duale assume particolare significato a questo riguardo. Infine, il calibramento del modello risperro ad un anno base aumenta la prospettiva di previsioni adeguate.

Does everything fall apart? Life assessments following a gray divorce
Creators: name: Crowley, Jocelyn Elise
Publisher: name: Rutgers University
Year: 2019
Subjects: Gray divorce
Adjustment
Divorce consequences
Interviews

description: The divorce-stress-adjustment theoretical framework emphasizes the negative consequences associated with marital dissolution, but also the positive outcomes that can eventually emerge after former spouses part ways. This study aims to examine the subjective life assessments of the heterosexual gray divorced population within the first three years of their marital splits with respect to this framework. Qualitative data based on 66 in-depth interviews of the gray divorced population were collected and analyzed using grounded theory methods. Negative consequences of gray divorce included financial worries and loneliness. However, participants also identified positive aspects of their new lives, including higher levels of overall happiness, liberation from their ex-spouses, and enhanced independence and freedom. These results show that immediately after their marriages dissolve, members of the gray divorced population experience complex reactions in accordance with the divorce-stress-adjustment framework. More specifically, these men and women see both challenges and opportunities after their gray divorces.

Multi-resolution state retrieval in sensor networks

description: Large-scale sensor networks require mechanisms to extract topology information that can be used for various aspects of sensor network management. It is critical for any topology discovery algorithm in sensor networks to adhere to the resource constraints of bandwidth and energy. In this paper, we describe a distributed parameterized algorithm for Sensor Topology Extraction at Multiple Resolutions (STEM), which makes a tradeoff between topology details and resource expended. The algorithm retrieves network state at multiple resolutions at a proportionate communication cost. We also define various classes of topology queries and show how the parameters in the algorithm can be used to support queries specific to sensor networks. We show that the topology determined, albeit at a low resolution, is sufficient for approximating actual network properties. Finally we show how STEM can be used for generalpurpose multi-resolution information retrieval in sensor networks.

Gini index decomposition for the case of two subgroups
Creators: name: Costa, Michele
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2007

description: Gini inequality index decomposition into within and between inequality components arises since a long time a controversial, wide and interesting discussion. The measurement of inequality between is traditionally obtained in the framework of analysis of variance as a function of only the means of the subgroups. An alternative methodology to measure inequality between states the possibility to take into account all differences between subgroups distributions. By referring to this new approach, the paper introduces a relevant simplification of the measurement of inequality between and of the transvariation contribution for the case of a population divided in two subgroups. Without transvariation, inequality between can be obtained as the difference of the poor share in the population and the poor share in the variable of interest. Also for the case of two overlapping subgroups simple and straightforward expressions for the transvariation contribution and inequality between are derived.

Chemical Oxidation of High-Density Polyethylene : Surface Energy, Functionality and Adhesion to Liquid Epoxy
Creators: name: Azimi, Mohammadyousef

Publisher: name: Wiley
Year: 2022

description: The application of polyolefins has increased significantly over the past few decades. However, their chemical inertness and low surface energy limits their application in many industries where high adhesion to polar materials is required, such as for composites and protective coatings. Herein, six different acids are used to create polar functional groups on High-Density Polyethylene’s (HDPE) surface and to increase its adhesion to liquid epoxy (LE). Contact angle measurements, Fourier Transform Infrared spectroscopy (ATR-FTIR), X-ray photoelectron spectroscopy (XPS) and pull-off strength measurements are used to analyze the surface energy and functionality of HDPE and to measure its adhesion to LE. The results show that each acid increases both the polar and disperse surface energies of HDPE to a different extent, but that this is not necessarily a function of acid strength. Chlorosulfonic acid and chromic acid increase the oxygen to carbon ratio by a factor of 8 and increase HDPE’s adhesion to LE by more than 400%. Furthermore, a comparison between predicted work of adhesion values from the OWRK model and experimental results shows that the latter are significantly higher than what is predicted, especially with increasing surface polarity.
