K-core: Theories and applications

Kong, Yi-Xiu ; Shi, Gui-Yuan ; Wu, Rui-Jie ; Zhang, Yi-Cheng

In: Physics Reports, 2019, vol. 832, p. 1–32

With the rapid development of science and technology, the world is becoming increasingly connected. The following dire need for understanding both the relationships amongst individuals and the global structural characteristics brings forward the study of network sciences and many interdisciplinary subjects in recent years. As a result, it is crucial to have methods and algorithms that help us...

Application mobile : notation, évaluation et recommandation des vins suisses aux consommateurs locaux

Diep, Edouard ; Stettler, Christian (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2019 ; TDIG 174.

L’idée globale de ce projet est de développer une application mobile compatible multi-plateformes (iOS et Android) afin de permettre aux consommateurs de vins vaudois de tous registres confondus (amateurs comme experts) de pouvoir noter et évaluer les vins qu’ils dégustent, que cela soit dans le cadre d’un achat au supermarché, d’un accompagnement lors d’un repas au restaurant ou...

Automatically testing interactive applications : exploiting interactive applications semantic similarities for automated testing

Zuddas, Daniele ; Pezzè, Mauro (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO006.

Interactive applications, such as mobile or web apps, have become essential in our lives and verifying their correctness is now a key issue. Automatic system test case generation can dramatically improve the testing process for these applications and has recently motivated researchers to work on this problem defining a wide range of different approaches. However, most state-of-the-art...

Discoverers in scientific citation data

Shi, Gui-Yuan ; Kong, Yi-Xiu ; Yuan, Guang-Hui ; Wu, Rui-Jie ; Zeng, An ; Medo, Matúš

In: Journal of Informetrics, 2019, vol. 13, no. 2, p. 717–725

Identifying the future influential papers among the newly published ones is an important yet challenging issue in bibliometrics. As newly published papers have no or limited citation history, linear extrapolation of their citation counts—which is motivated by the well-known preferential attachment mechanism—is not applicable. We translate the recently introduced notion of discoverers to...

Competition may increase social utility in bipartite matching problem

Kong, Yi-Xiu ; Yuan, Guang-Hui ; Zhou, Lei ; Wu, Rui-Jie ; Shi, Gui-Yuan

In: Complexity, 2018, p. -

Bipartite matching problem is to study two disjoint groups of agents who need to be matched pairwise. It can be applied to many real-world scenarios and explain many social phenomena. In this article, we study the effect of competition on bipartite matching problem by introducing conformity into the preference structure. The results show that a certain amount of competition can improve the...

Instability in stable marriage problem: matching unequally numbered men and women

Shi, Gui-Yuan ; Kong, Yi-Xiu ; Chen, Bo-Lun ; Yuan, Guang-Hui ; Wu, Rui-Jie

In: Complexity, 2018, p. -

The goal of the stable marriage problem is to match by pair two sets composed by the same number of elements. Due to its widespread applications in the real world, especially the unique importance to the centralized matchmaker, a very large number of questions have been extensively studied in this field. This article considers a generalized form of the stable marriage problem, where different...

The earliest evidence for Upper Paleolithic occupation in the Armenian Highlands at Aghitu-3 Cave

Kandel, Andrew W. ; Gasparyan, Boris ; Allué, Ethel ; Bigga, Gerlinde ; Bruch, Angela A. ; Cullen, Victoria L. ; Frahm, Ellery ; Ghukasyan, Robert ; Gruwier, Ben ; Jabbour, Firas ; Miller, Christopher E. ; Taller, Andreas ; Vardazaryan, Varduhi ; Vasilyan, Davit ; Weissbrod, Lior

In: Journal of Human Evolution, 2017, vol. 110, no. Supplement C, p. 37–68

With its well-preserved archaeological and environmental records, Aghitu-3 Cave permits us to examine the settlement patterns of the Upper Paleolithic (UP) people who inhabited the Armenian Highlands. We also test whether settlement of the region between ∼39–24,000 cal BP relates to environmental variability. The earliest evidence occurs in archaeological horizon (AH) VII from...
