Design of modern engineering products requires complexity management. Several methodologies for complex system optimization have been developed in response. Single-level strategies centralize decision-making authority, while multi-level strategies distribute the decision-making process. This article studies the impact of coupling strength on single-level Multidisciplinary Design Optimization fo...
This paper introduces Contextual Salience (CoSal), a simple and explicit measure of a word’s importance in context which is a more theoretically natural, practically simpler, and more accurate replacement to tf-idf. CoSal supports very small contexts (20 or more sentences), out-of context words, and is easy to calculate. A word vector space generated with both bigram phrases and unigram tokens ...

Keyword extraction by Term frequency-Inverse document frequency (TF-IDF) is used for text information retrieval and mining in many domains, such as news text, social contact medical text. However, keyword special domains still needs to be improved optimized, particularly the scientific research field. The traditional TF-IDF algorithm considers only word documents, but not domain characteristics...
background: the homeostasis model assessment of insulin resistance (homa-ir) is a useful model for application at large epidemiologic studies. the aim of this study was to determine the homa cut off values to identify insulin resistance (ir) and metabolic syndrome (ms) in qazvin, central iran. methods: overall, 480 men and 502 women aged 20-72 yr attended in this cross sectional study from sept...
considering the fact that many muslims with diabetes prefer to fast in spite of inhibitory advises and to answer several conflicts and controversies regarding diabetes and ramadan, idf in collaboration with diabetes and ramadan (dar) international in alliance decided to develop a comprehensive guideline to be used by health care professionals. this guideline was then developed on april 2016 by ...
The International Diabetes Federation (IDF) recently published guidelines for the management of postmeal hyperglycemia. These guidelines were established in view of the risk of postmeal hyperglycemia for vascular events. Because of the rising incidence and prevalence of diabetes and its complications, the IDF took action to state useful strategies for the treatment of diabetes, focusing on the ...
Design of complex products with several interacting subsystems or disciplinary analyses poses substantive challenges to both analysis and optimization, necessitating specialized solution techniques. A product or system may qualify as complex due to large scale or due to strong interactions. Single-level strategies for complex system optimization centralize decision-making authority, while multi...
Structured document retrieval aims at retrieving the document components that best satisfy a query, instead of merely retrieving pre-de ned document units. This paper reports on an investigation of a tf -idf -acc approach, where tf and idf are the classical term frequency and inverse document frequency, and acc, a new parameter called accessibility, that captures the structure of documents. The...
In many natural language processing tasks, a document is commonly modeled as a bag of words using the term frequency-inverse document frequency (TF-IDF) vector. One major shortcoming of the TF-IDF feature vector is that it ignores word orders that carry syntactic and semantic relationships among the words in a document. This paper proposes a novel distributed vector representation of a document...
