Content dissemination over vehicular networks is a critical challenge due to its high intermittent connectivity. However, content cache and retrieval by exploiting the information-centric networking (ICN) paradigm did not get much attention. In this paper, in order to improve the efficiency of content retrieval, we propose a novel popularity-aware content caching and retrieving strategy in VANE...

In order to realize economic and social green development, to pave a pathway towards China’s green regional development and develop effective scientific policy to assist in building green cities and countries, it is necessary to put forward a relatively accurate, scientific and concise green assessment method. The research uses the CCR (A. Charnes & W. W. Cooper & E. Rhodes) Data Envelopment An...

Data Envelopment Analysis appeared in 1978 when the first model, known as CCR was proposed by Charnes et al. (1978). This model calculates the efficiency of productive units, known as DMUs Decision Making Units, by comparing the use of resources (inputs) and the production (outputs) obtained. This model considers Constant Returns to Scale (CRS), i.e., an increase in resources generates a propor...

a new algorithm for classification of dmus to efficient and inefficient units in data envelopment analysis is presented. this algorithm uses the non-archimedean charnes-cooper-rhodes[1] (ccr) model. also, it applies an assurance value for the non-archimedean                          using only simple computations on inputs and outputs of dmus (see [18]). the convergence and efficiency of the ne...

In July 1977, 50,000 Christians from different backgrounds and traditions converged on Kansas City to participate in the Conference Charismatic Renewal Christian Churches. Catholic charismatics played a key role its organization, relying all their ecumenical contacts built since origins of (CCR) 1967 at Duquesne University Pittsburgh (PA). If conference represented zenith shared unified vision ...

Abstract Aims Current guidelines recommend surveillance colonoscopy at one year following Colorectal Cancer Resection (CCR), yearly CT chest, abdomen and pelvis, CEA, in 3 years. Previous studies showed no significant difference between CTC detection rates of colorectal cancer or polyps >6mm. A review abnormalities detected on colonoscopies CCR. If the incidence is low Colonography (CTC)...

Extending a result of the first author and Katsura, we prove that for every UHF algebra [Formula: see text] infinite type, in uncountable cardinality there are nonisomorphic approximately matricial C*-algebras with same group as text]. These algebras “twisted” by prescribed canonical commutation relations (CCR), they can also be considered nonseparable generalizations noncommutative tori.

Anchor DMUs are a new class in the general classification of Decision Making Units (DMUs) in Data Envelopment Analysis (DEA). An anchor DMU in DEA is an extreme-efficient DMU that defines the transition from the efficient frontier to the free-disposability part of the boundary of the Production Possibility Set (PPS). In this paper, the anchor points of the PPS of the CCR model are investigated....
