8 Abstract This research presents a bus fleet replacement optimization model to 9 analyze vehicle replacement decisions when there are competing technologies. The 10 focus of the paper is on sensitivity analysis. Model properties that are useful for 11 sensitive analysis are derived and applied utilizing real-world data from King 12 County (Seattle) transit agency. Two distinct technologies, di...

— This paper summarizes ten replacement models which combine tkree basic replacements: (i)age replacement; (ii)block replacement; (in) periodic replacement with minimal repair at failure. The expected cast rates ofeach model are derived, using the usual caktdus method ofprobabitity. As an example, we give an optimum policy to minimize the expected cost rate ofone model

electric power industry have always try to provide reliable electricity to customers and at the same time decrease system costs. high voltage circuit-breakers are an essential part of the power network. this study has developed a maintenance and replacement scheduling model for high voltage circuit- breakers that minimize maintenance costs while maintaining the acceptable reliability. this mode...

introduction: in order to make a dimensional proportion between human and equipment or environment, anthropometric data bank is essential. anthropometry has an important role in industrial management and ergonomic design. this information is needed to be collected regularly in every society. the purpose of this study was to determine arm length to height ratio according to gender in adults, bet...

[1] A rock magnetic cyclostratigraphy, based on anhysteretic remanent magnetization (ARM) intensity variations, was developed for the Eocene Arguis Formation in the Spanish Pyrenees. The Arguis Formation was sampled for ARM cyclostratigraphy, rock magnetic, and paleomagnetic analyses. Rock magnetic measurements indicate that the dominant magnetic mineral controlling the ARM cyclostratigraphy is...

certificateless public key cryptography (cl-pkc) is a useful method in order to solve the problems of traditional public key infrastructure (i. e. large amount of computation, storage and communication cost for managing certificates) and id-based public key cryptography (i. e. key escrow problem), simultaneously. a signcryption scheme is an important primitive in cryptographic protocols which p...

In many area of medical research, a relation analysis between one response variable and some explanatory variables is desirable. Regression is the most common tool in this situation. If we have some assumptions for such normality for response variable, we could use it. In this paper we propose a nonparametric regression that does not have normality assumption for response variable and we focus ...

the aim of this study was to investigate anthropometric and physiological characteristics in junior volleyball players for talent identification according to their volleyball playing positions. 15 junior national volleyball players (mean age 17.7±0.3 years) participated in this study. players were classified to five groups according to their playing positions: setters, liberoes, middle blockers...
