In this study, sea-urchin shaped Bi2S3/CdS hierarchical heterostructures are successfully synthesized via a convenient one-pot growth rate controlled route. The product is mainly composed of Bi2S3 nanorods and CdS nanoparticles grown on their surfaces. The formation mechanism was proposed based on the evolution of morphology as a function of solvothermal time, which involves fast formation of t...

In this paper, we describe a content language for a hierarchically organized production control system in semiconductor manufacturing. The semiconductor manufacturing domain is characterized by re-entrant product flows, sequence-dependent setup-times, prescribed due-dates, a diverse product mix, a mix of different process types including batch processes and preventive maintenance issues caused ...

A method is proposed for evaluating the effectiveness of robust parameter design methods. A hierarchical probability model is presented that enables an investigator to represent assumptions about regularities in system responses such as effect sparsity, hierarchy, and inheritance. The hierarchical probability model is subsequently used to create a population of responses to which alternative ro...

abstract purpose of this paper: the objectives of this paper are two folds: (1) utilizing hierarchical fuzzy technique for order preference by similarity to ideal solution (topsis) approach to evaluate the most suitable rfid-based systems decision, and (2) to highlight key risks and benefits of radio frequency identification technology in healthcare industry. design/methodology/approach: resear...

Product development processes are flexible and dynamic in nature. In this domain, workflows are commonly used for representing business processes in change management or for document management. The product development process itself can hardly be represented by a business process that is defined in a design phase and fixed during runtime. However, the workflow technique can be extended by conc...

This paper describes a hierarchical neural network we propose for sentence classification to extract product information from product documents. The network classifies each sentence in a document into attribute and condition classes on the basis of word sequences and sentence sequences in the document. Experimental results showed the method using the proposed network significantly outperformed ...

This is a discussion of the essential features of product development traceability maps in relation to requirements, architecture, functional models, components, and tests as a set of order type hierarchies and their cross-links. This paper lays out the structure of these ideal traceability relationships that define the essence of the product under development. The importance of the trace relat...

The German Remote Sensing Data Center (DFD) has developed a digital library for the long-term management of earth observation data products. This Product Library is a central part of DFD’s multi-mission ground segment Data Information and Management System (DIMS) and is successfully in operation since 2000. Its data model is regularly extended to support products of upcoming earth observation m...
