We investigate the aggregation phase of multicriteria decision making procedures. Characterizations of some classes of nonconventional aggregation operators are established. The first class consists of the ordered weighted averaging operators (OWA) introduced by Yager. The second class corresponds to the weighted maximum defined by Dubois and Prade. The dual class (weighted minimum) and some or...

BACKGROUND Obesity, a worldwide pandemia, is associated with a large variety of comorbidities, among which is non-alcoholic fatty liver disease. NAFLD is a complex disease that may eventually lead to cirrhosis, posing a high risk for the patient and thus necessitating early diagnosis and treatment. OBJECTIVES To evaluate the association between ultrasonographically diagnosed non-alcoholic fat...

We suggest an approach to the aggregation of non-independent belief structures that makes use of a weighted aggregation of the belief structures where the weights are related to the degree of dependence. It is shown that this aggregation is non-commutative, the fused value depends on the sequencing of the evidences. We then consider the problem of how best to sequence the evidence. We investiga...

In this paper, we propose a novel personalized aggregation approach to the multidimensional relevance aggregation. The approach is based on a mathematical aggregation operator relying on a fuzzy measure that allow to quantify the importance degree of each relevance dimension for every user as well as the interaction existing between the criteria. The evaluation of our approach is performed on t...

We restate the problem of judgment aggregation and approach it using the decisiontheoretic framework applied by I. Levi to modeling acts of rational acceptance in science. We propose a method of aggregation built on the concepts of epistemic and social utility of accepting a collective judgment, which accounts for such parameters as the factual truth of the propositions, reliability of agents, ...

Designing secure data aggregation schemes, which are critical to many sensor network applications, imposes interesting and formidable challenges. In this paper, we propose a succinct and practical secure aggregation protocol by combining HMAC (associated with a cryptographic hash function) with Bloom filter, which then is defined as secure Bloom filter. Unlike most previous approaches, which ar...

In this paper, aggregation behaviors of aqueous solutions of short chain hydrophilic Ionic Liquids (ILs), 1 – allyl - 3 - methylimidazolium chloride ([Amim]Cl), 1 - ethyl - 3 - methylimidazolium chloride ([Emim]Cl), 1 - butyl - 3 - methylimidazolium chloride ([Bmim]Cl), 1 - butyl - 3 - methylimidazolium tetrafluoroborate ([Bmim]BF4) were investigated using conductivity and laser ...

Existing works on data aggregation in wireless sensor networks (WSNs) usually use a single channel which results in a long latency due to high interference, especially in high-density networks. Therefore, data aggregation is a fundamental yet time-consuming task in WSNs. We present an improved algorithm to reduce data aggregation latency. Our algorithm has a latency bound of 16R + Δ – 11, where...

The molecular nature of cell adhesion mediated by platelet/endothelial cell adhesion molecule 1 (PECAM-1; CD31) was examined using stably transfected L cells in a PECAM-dependent aggregation assay. This adhesion was temperature sensitive and divalent cation dependent, with Mg2+ supporting aggregation to a greater degree than Ca2+. PECAM-dependent aggregation was heterophilic: PECAM-1 transfecta...
