Sucrose solutions, with concentrations near or superior to saturation, present high potentialities for the candy and pastry industries. Creep measurements under small stresses were done to obtain the rheological properties of highly concentrated sucrose solutions, since such solutions could be in a metastable state and tend to crystallise. The viscosities of these solutions, from 70.0% to 85.2%...

Most low water content or frozen food products are partly or fully amorphous. This review will discuss the extent to which it is possible to understand and predict their behavior during processing and storage, on the basis of glass transition temperature values (Tg) and phenomena related to glass transition. Two main conclusions are provisionally proposed. Firstly, glass transition cannot be co...

The continuous emission spectra of Hα, Hβ, and Hγ wave bands of the solar flare of 5 July 1989 have been analysed. We demonstrate that the flare not only emits at the line centres and wings of Hα, Hβ, and Hγ, but also in the continuum near these lines. The positions, durations, and configurations of the four flare kernels are respectively similar to those of a white light flare (WLF). Therefore...

Wei Huang: Managing Warranty Services: Pricing, Inventory and Outsourcing (Under the direction of Jayashankar Swaminathan, Vidyadhar Kulkarni) Managing warranty services plays a very important role in today’s business environment. This thesis concentrates on three specific areas related to warranty: joint control of new and warranty parts inventory, outsourcing of repair services, coordinated p...

For repairable items under the two-dimensional warranty, the manufacturer expenses warranty costs for rectifying the failures occurring over the warranty coverage. Preventive maintenance actions reduce the occurrence intensity of item failures, and hence the warranty cost resulted from corrective maintenance, but bring additional preventive maintenance cost. In this paper, we investigate a peri...

Purpose – The purpose of the paper is to develop a conceptual framework that integrates the technology and commercial issues early at the design stage to minimize warranty costs in the most effective and efficient manner and also to develop a model for optimization of warranty with specific focus on reliability and warranty policies. Design/methodology/approach – The critical issues in warranty...

     The quadratic loss function has been used by decision-theoretic statisticians and economists for many years.  In this paper  the estimation of scale parameter under a bounded loss function, which is adequate for assessing quality and quality improvement, is considered with restriction to the principles of invariance and risk unbiasedness. An implicit form of minimum risk scale equivariant ...

This paper studies the joint optimization of price and two-dimensional (2-D) warranty policy with limits both length usage. For this purpose, in paper, we first propose a new sales function to characterize influence price, length, usage limit on rate while considering heterogeneous customer rate. Then, model dynamic 2-D as nonlinear optimal control problem, solve it via numerical approach based...

BACKGROUND AND OBJECTIVES Few quantitative studies have investigated the temperature dependent viscoelastic properties of cartilage tissue. Cartilage softens and can be reshaped when heated using laser, RF, or contact heating sources. The objectives of this study were to: (1) measure temperature dependent flexural storage moduli and mechanical relaxation in cartilage, (2) determine the impact o...

In this paper, we have proposed a bi-objective model for pricingqueuing problem under fuzzy environment. The objectives are maximizing the profit and minimizing the waiting time in system to receive the service. Price, warranty length, and service capacity decisions are analyzed for a seller with considering sale and service channels. To formulate the demand function, a fuzzy system is develope...
