a r t i c l e i n f o Innovation-driven durable goods markets see substantial changes in quality and available choice sets and subsequent changes of the reference quality in the market over time. Considering the multi-attribute characteristics of these goods, it is important for businesses to identify attribute-specific competitive landscapes and develop competitive innovation strategies at the...

observing the correct principles of sterilization is one of the most important strategies to prevent infection transmission and, also, to reduce the time and the cost of research projects in biological sciences. the aim of this study is to evaluate the awareness of employees in a research laboratory in an institute of medical sciences. in this cross-sectional study, a questionnaire was designed...

conclusions considering the weight percentage of food wastes (70%), solid wastes of babolsar city could be used for composting. also as large quantities of infectious wastes were produced by hospitals of babolsar, it is recommended that sterilization systems (hydroclave) be used for decontamination of these hazardous wastes. materials and methods this study was a descriptive and cross-sectional...

The entity attribute extraction problem, or how to extract entities and their attribute values from natural language Web documents, is of critical importance for Web search and information access in general. Unfortunately, because of the noisy nature of theWeb and its scale, entity attribute extraction is notoriously challenging in terms of both extraction efficiency and quality. In our earlier...

Data access control is an effective way to ensure the data security in the cloud. Due to data outsourcing and untrusted cloud servers, the data access control becomes a challenging issue in cloud storage systems. Ciphertext-Policy Attribute-based Encryption (CP-ABE), as a promising technique for access control of encrypted data, is very suitable for access control in cloud storage systems due t...

This paper presents our efforts in the updating of the Storm Water (SW) Database using Global Positioning System (GPS), direct survey and measurements of the Storm Water structures (or called Manhole) in GIS database management. The main task assignments include (1) Designing a data structure, which becomes an effective geodatabase structure to represent the storm water structures and the corre...

living in satisfying urban environments is important for an individual’s well-being. in order to create such environments, planners, designers, and policy makers need to understand the structures that cause residents to feel satisfied with their environments. this paper focuses on the perceived quality of urban residential environments: dwellings and neighborhoods. first, literature review was ...

In the present paper we propose an unsupervised attribute ranking method based on evaluating the quality of clustering that each attribute produces by partitioning the data into subsets according to its values. We use the Minimum Description Length (MDL) principle to evaluate the quality of clustering and describe an algorithm for attribute ranking and a related clustering algorithm. Both algor...

This paper introduces object-oriented attribute grammars. These can be characterized as a notation for all classes of attribute grammars. Based on a subtype relation between grammar rules, inheritance of attributes and attribute computations are defined. With this approach, attributes local to grammar rules and the elimination of chain rules are possible without any special constructs. We prese...

Cloud storage enables users to remotely store their data and enjoy the on-demand high quality cloud applications without the burden of local hardware and software management. Though the benefits are clear, such a service is also relinquishing users’ physical possession of their outsourced data, which inevitably poses new security risks towards the correctness of the data in cloud. In order to a...
