Using operating ratio and return on assets (ROA) for the two kinds of profitability indicators to measure insurers’ profitability. The results show that underwriting risk, reins...

this study investigates the prediction model of compressive strength of self–compacting concrete (scc) by utilizing soft computing techniques. the techniques consist of adaptive neuro–based fuzzy inference system (anfis), artificial neural network (ann) and the hybrid of particle swarm optimization with passive congregation (psopc) and anfis called psopc–anfis. their performances are comparativ...

This paper reports the results of an experimental investigation on the effect of the EGR on the pollutants emission, especially on oxides of nitrogen, from the exhaust gases and performance of the spark ignition engine. Also along with experimental work, a mathematical model for the determination of the effect of EGR on the peak cycle temperature and for the prediction of its effect on the NOx ...

the pediatric risk of mortality (prism) score is a measure of illness severity based on abnormalities observed on bedside examination and laboratory assessment at pediatric intensive care unit (picu) admission to predict mortality probability. our study was performed on 205 patients who were admitted to picu of children’s medical center (cmc) over a period of 6 months.data were recorded prospec...

With an efficient working capital management, a firm can release capital for more strategic objectives, reduce the financial costs, and improve profitability. The present research studies the relationship of working capital management on performance of firms Listed in Tehran Stock Exchange (TSE). Average Collec...

In the prediction of turning points (TPs) time series, improved model integrating piecewise linear representation and weighted support vector machine (IPLR-WSVM) has achieved good performance. However, due to single data source limitation algorithm, IPLR-WSVM encountered challenges in profitability. this paper, a fusion method based on multi-source heterogeneous different learning algorithms is...

This study investigates the firm-specific factors affecting the profitability of non-life insurance companies operating in Turkey. For this purpose, data of 24 non-life insurance companies operating in Turkey from the period 2006–2013 were brought together to obtain 192 observed panel data sets. In this study, profitability is measured by two different variables: technical profitability ratio a...

In this study, we focus on the optional operating cash flow, optional cost and production cost as real earnings management representatives as well as discretionary accruals as an earnings management acco...

UNLABELLED BACKGROUND Aerobic capacity (VO2max) is highly dependent upon body composition of an individual and body composition varies with ethnicity. The purpose of this study was to check the concurrent validity of the non-exercise prediction equation developed by Jackson and colleagues (1990) using percentage body fat as a variable in Asian Indian adults. METHODS One hundred twenty coll...

The objective of the study was to develop prediction equations for fat-mass percentage in infants in India based on skinfold thickness, mid-arm circumference, and age. Skinfold thicknesses and mid-arm circumference of 46 apparently-healthy infants (27 girls and 19 boys), aged 6-24 months, from among the urban poor attending a well baby clinic of a hospital in Kolkata were measured. Their body-f...
