The Treatment of Ties in AP Correlation
No full textThe Kendall tau and AP correlation coefficients are very commonly use to compare two rankings over the same set of items. Even though Kendall tau was originally defined assuming that there are no ties in the rankings, two alternative versions were soon developed to account for ties in two different scenarios: measure the accuracy of an observer with respect to a true and objective ranking, and measure the agreement between two observers in the absence of a true ranking. These two variants prove useful in cases where ties are possible in either ranking, and may indeed result in very different scores. AP correlation was devised to incorporate a top-heaviness component into Kendall tau, penalizing more heavily if differences occur between items at the top of the rankings, making it a very compelling coefficient in Information Retrieval settings. However, the treatment of ties in AP correlation remains an open problem. In this paper we fill this gap, providing closed analytical formulations of AP correlation under the two scenarios of ties contemplated in Kendall tau. In addition,we developed an R package that implements these coefficients.Best Short Paper Accepted author manuscriptMultimedia ComputingWeb Information System

Parallel Process Management on the
No full textThis paper discusses tools and mechanisms developed for running parallel applications on the AP1000+ under AP/Linux. The main themes considered are the architecture of the parallel process management programs, and how they enable greater flexibility in configuring parallel applications over the AP1000+ cells. How these mechanisms enable dynamic partitioning and load balancing for multiple users is considered, as well as how message passing is implemented to allow optimised global reduction operators within a multi-user environment. 1 Introduction During the previous year, the AP/Linux operating system [3] was developed for the Fujitsu AP1000+. It demonstrated the viability of a long lived, robust, feature rich operating system. Associated with this development were the initial parallel application management systems, including the CellOS compatible APlib message passing library and the parallel daemon responsible for launching parallel applications.

Dalla risorgenza alla restaurazione: il dialetto fra nostalgia, rivendicazioni identitarie e appropriazioni indebite
No full textViene proposta una riflessione sullo stato del dibattito pubblico sul dialetto,
un codice che oggi perde parlanti, ma guadagna nuovi ambiti di uso e una considerazione
positiva che lo rende attraente e utilizzabile in ambiti diversi rispetto a quello della
comunicazione ordinaria.
Vengono presentate alcune iniziative, collocabili a pieno titolo fra le “risorgenze dialettali”
che sempre più spazio e successo stanno trovando negli ultimi anni in conseguenza
della perdita dello stigma negativo nei confronti delle varietà locali (sdoganamento).
Viene discusso il fenomeno delle “Accademie” che, fondate con lo scopo di “promuovere”
il dialetto, ne forniscono sistemi di scrittura, saggi di grammatica, profili
geo- sociolinguistici, “corsi di apprendimento”, con la messa a punto di strumenti molto
spesso non sostenuti da un adeguato impianto teorico o dalla consapevolezza che il dialetto
come codice della “cultura dialettale” diventa “lingua” solo a prezzo di un processo
di “ausbauizzazione forzata”
Delamination Analysis of A Class of AP-PLY Composite Laminates
No full textA recently developed fiber placement architecture, AP-PLY, has been shown to give significantly improved damage tolerance characteristics of composite structures. The behavior of delaminations resulting from low speed impact damage is of particular concern. Major attention has been paid to expand current knowledge on the delamination response of simple AP-PLY composite structure and move towards in-depth understanding of the failure mechanisms behind the damage tolerance. This thesis presents the approaches to predict delamination onset and analyze delamination growth, in support of the search of the optimum woven pattern for AP-PLY composite laminates. The recovered interlaminar stress between layers combined with the maximum stress criterion determined the delamination onset of simple AP-PLY composite laminate under out-of-plane loads. 2D finite element models with cohesive elements inserted in the interfaces of woven layers have been built to evaluate the delamination initiation and propagation in the different woven patterns of simple AP-PLY composite beams. The parameters of the woven pattern, such as the woven angle, the number of woven plies, the number of straight filled plies, and the location of the woven patterns in through the thickness direction, were investigated and shown to have a significant effect on delamination creation and growth. An energy method based on beam theory was proposed to analyze the strain energy release rate (SERR) of an existing crack in an AP-PLY beam structure. The developed analytical method was implemented in isotropic materials and the obtained SERR of a crack was validated by reference results and finite element solutions. The general behavior of crack growth on the left or right crack tip was evaluated and basic trends leading to crack propagation on one side of the crack were established. A correction factor was introduced to improve the accuracy of the SERR of a small crack through the numerical calculation. The singularity of crack tip caused by dissimilar materials was investigated and was found that the inclusion of the singularity effect could increase the accuracy for small cracks. It has been shown that the neutral axis needs to be relocated to decouple the bending and membrane behavior of unsymmetrical composite laminates, thus to meet the requirement of minimizing the strain energy of the delaminated beam to calculate the SERR of a delaminated composite beam. The calculated SERR of a crack in a composite beam has been verified by comparing with a finite element model. The woven plies in AP-PLY composite laminate altered the layup and two conventional laminates with different stacking sequences were identified in an AP-PLY composite laminate based on the assumption that the resin areas were ignored. A step by step approach was developed to obtain the SERR of a crack that goes across different materials. The analytical SERR determined when two materials are used in sequence, sets the stage for optimization of AP-PLY composite laminates without taking account of the effect of the resin area. The procedure of optimization of simple AP-PLY pattern was proposed and industry may benefit for many applications. An equivalent stiffness approach was used to model regions containing resin pockets and straight or inclined composite layers. A series of three point bending tests was carried out where the failure process and loading capacity were evaluated. The methodology, procedure of optimization, philosophy outlined in this thesis might also be applied to the more complicated fully woven AP-PLY composite laminates. The work in this thesis contributes to the understanding of the behavior of AP-PLY composite laminates with delaminations
Structure function analysis of blazars AP Librae and 3c279
No full textHighest Honors in AstronomyBlazars AP Librae and 3c279 are analyzed for microvariability using a technique known as structure function analysis. AP Librae was observed in April
of 2005 and 3c279 was observed in April of 2007. The data for AP Librae was
previously reduced by Andrew Collazzi and the author reduced the data for
3c279. Both sets of data were reduced using Robert Knop's data reduction
program.
The author ran structure function analysis on both sets of data. Structure function analysis is a statistical analysis run on data that is suppose to
nd timescales of variability, periodicity, and the noise type of data. Previous analysis of AP Librae confirmed mircrovariability, which also shows up in
the structure function of AP Librae. Blazar 3c279 was much quieter than AP
Librae and showed no microvariability durning any of the nights.College of Arts and ScienceDepartment of Physics and Astronom

Implementing the Combination of Time Sharing and Space Sharing on AP/Linux
No full text| We report the implementation of a scheduling method which combines time sharing and space sharing on AP/Linux. To run many tasks simultaneously on a parallel computer, the parallel computer system needs a partitioning algorithm that can partition processors for incoming tasks. However, a typical problem for the algorithm is a blockade situation, which causes low processor utilization and slow response. To avoid such a situation, we present a Time Sharing System (TSS) scheme that uses a partitioning algorithm. In this paper we state the implementation design of our TSS on a real parallel computer, the Fujitsu AP1000+. The design is based on the parallel operating system, AP/Linux. We report our current implementation and the performance. Keywords: time sharing, space sharing, partitioning algorithm, AP/Linux I. Introduction Parallel computers are becoming more popular for many applications and many commercial parallel computers are on the market. Since every application cannot util..
