A probabilistic high cycle fatigue model applied to cast Al-Si alloys

In this work, the high cycle fatigue behavior of cast hypo-eutectic Al-Si alloys is investigated. It is observed that two different coexisting fatigue initiation mechanisms can occur in these materials depending on the presence of different microstructural heterogeneities (i.e. micro-shrinkage pores, Si particles, Fe-rich inter-metallics, DAS of the Al-matrix, etc).Firstly, an experimental study is presented, highlighting the coexistence of these two fatigue damage mechanisms and their dependence on the presence of different micro-structural heterogeneities. A probabilistic high cycle fatigue model, which has the capacity to describe these two mechanisms, is then presented. The model contains the same principal ingredients as the one developed by [1]. It uses a probabilistic framework to link the two different fatigue damage mechanisms, and can take into account the mean stress and the effect of a biaxial stress state.This work was undertaken in partnership with PSA Peugeot Citrooën and was financially supported by the French region, Pays de la Loire

Babad Arya Tabanan dan Ratu Tabanan

Istilah babad pada umumnya berlaku bagi karya sastra yang mengungkapkan cerita seja~ah, berbahasa Sunda, Jawa, Bali, Lombok, dan Madura. Darusuprapta (1984:10) menyatakan babwa babad adalah istilah yang dipakai untuk menyebut salah satu jenis karya sastra Jawa, Sunda, Bali, dan Lombok yang dipandang masib banyak mengandung unsur sejarah dengan menggunakan bahasa daerah masing-masing. Oleh karena itu, Darusuprapta menggolongkan babad ke dalam golongan sastra sejarah

Supply Response of Paddy in East Java: Policy Implications to Increase Rice Production

An increasing population in recent decades has led to the need for increasing the availability of food, so it is necessary to increase the production of paddy as quickly as possible. The aim of this research was to know the supply response of paddy in East Java to various price factors and non-price factors. In this research, the supply response was estimated by the paddy harvest areas in East Java using Cobb-Douglas model and Nerlove partial adjustment, and econometric analysis including stationarity test, cointegration test, and Error Correction Model (ECM). The data used in this research consisted of paddy harvest areas, grain price, corn price, irrigated land area and rainfall amount from 1991 to 2015. The speed of short-term adjustment to the long-term supply of rice was 2.79% and was corrected in the next period. In the short run, all variables did not have a high responsiveness to paddy supply, but in the long run, the irrigation area was very responsive to paddy supply in East Java with a value of elasticity of 1.79. Supply of paddy can be increased by increasing the real price of unhulled rice, the irrigated land, and harvested area of the previous period

The association between area level socio-economic position and oral health-related quality of life in the South African adult population

Objective: To investigate the association between arealevel socio-economic position (SEP) and oral health-related quality of life (OHRQoL). Methods: Data collected from a nationally representative sample of the South African population ?16 years old (n=3,003) included demographics, individual-level SEP measures and self-reported oral health status. OHRQoL was measured using the Oral Health Impact Profile-14 (OHIP-14). The General Household Survey (n=25,653 households) and Quarterly Labour Force Surveys (n~30,000 households/ quarter) were used to determine area-level SEP. Data analysis included a random-effect negative binomial regression model and Blinder-Oaxaca decomposition analysis. Results: Area-level deprivation was associated with more negative oral impacts, independent of an individual's SEP. Other significant predictors of oral impacts included having experienced oral pain and reporting previous dental visits. Area differences in dental attendance contributed the most (37.5%) to the observed gap in OHRQoL, explained by differences in area-level SEP, whereas individual-level SEP contributed the least (18.8%). In the more affluent areas, satisfaction with life in general and individuals' SEP were significantly positively associated with OHRQoL.DHE

Detection of a particular object from environmental images under various conditions

In a current study of environmental information, it is important to detect the particular object from environmental images under various conditions for security such as navigation system of ships, bird-watching for the prevention of various damage, invaders check and human rescue in the marine casualty. This paper deals with the image processing techniques for the detection of the rescue target as a particular object from environmental images. When a marine casualty occurs the detection of the rescue target such as life rafts depends on the visual search of human eyes. It is predicted, however, that human eyes sometimes lose their sight and the ability of the detection falls owing to the long flight and a bad weather. For a practical purpose of the prompt rescue of human life, the development of the searching support system in place of human eyes is required. To realize a new type searching system for the detection of the rescue target, the development of new type image processing techniques in real time manner is important. At the first step of our study, we attempt to develop image processing techniques, in order to accurately detect the rescue target under various </p
