The authors compared the abilities of descriptive and valuational health-related quality-of-life measures to discriminate healthy participants (n=39) from those on diets for dyslipidemia (n=35) and angina patients (n=30). On the rating scale, the time tradeoff, and the General Health Perception subscale of the SF-36 Health Survey, the participants with dyslipidemia or angina reported lower mean...

We study an inventory management mechanism that uses two stochastic programs (SPs), the customary one-period Assemble-to-Order (ATO) model and its relaxation, to conceive control policies for dynamic ATO systems. We introduce a class of ATO systems, those that possess what we call a ‘chained BOM’. We prove that having a chained BOM is a sufficient condition for both SPs to be L convex in the fi...

Message authentication is considered as a serious bottleneck to multicast security, particular for stream-type of traffic. The techniques of hash chaining and signature amortization have been proposed in many schemes for stream authentication, with or without multicast settings. However, none of them is optimal. They either have a large packet overhead or are not robust to packet loss. Some eve...

-7803-5886-4/00/$10.00© 2000 IEEE 247 one. Being converted to the chained form, a tractor and all trailers can be stabilized to desired positions via. esla.I)lished nonholonomie motion control strategies for the chained form[5, 6, 7]. S0rdalen, Naka~ mura and Chung[8] developed "t, he nonholonomic manipulator," whose kinematic model is similar to those of trailer systems. The real-world tra~jec...

the concept of fuzzy soft γ-ring is introduced; and some properties of fuzzy soft γ-rings are given. then the definitions of fuzzy soft γ-ideals are proposed and some of their theories are considered.

This paper studies barrier options which are chained together, each with payoff contingent on curved barriers. When the underlying asset price hits a primary curved barrier, a secondary barrier option is given to a primary barrier option holder. Then if the asset price hits another curved barrier, a third barrier option is given, and so on. We provide explicit price formulas for these options w...

This paper addresses the problem of feedback stabilization of nonholonomic chained systems within the framework of nonregular feedback linearization. Firstly, the nonsmooth version of nonregular feedback linearization is formulated, and a criterion for nonregular feedback linearization is provided. Then, it is proved that a chained form is linearizable via nonregular feedback control, thus enab...

Frequency estimation (also called post-stratification) is an equating method employed under the common-item nonequivalent groups design. A modified frequency estimation method is proposed here, based on altering one of the traditional assumptions in frequency estimation in order to correct for equating bias. A simulation study was carried out to compare equating errors for the modified frequenc...
