Service Provisioning and User Association for Heterogeneous Wireless Railway Networks
2017
In addition to comforting passengers' journey, the modern railway system is responsible to support a variety of on-board Internet services to meet the passenger's demands on seamless service provisioning. In order to provide wireless access to the train, one idea attracting increasing attention is to deploy a series of track-side access points (TAPs) with high-speed data rates along the rail lines dedicated to the broadband mobile service provisioning on board. Due to the heavy data traffic flushing into the base stations (BSs) of the cellular networks, TAPs act as a complement to the BSs in data delivery. In this paper, we focus on the TAP association problem for service provisioning in a …
Service Provisioning with Multiple Service Providers in 5G Ultra-dense Small Cell Networks
2015
In this work, a game theoretical approach for addressing the virtual network service providers (NSPs), small cell provider (SCP) and user interaction in heterogenous small cell networks is presented. In particular, we consider the users can select the services of different NSPs based on their prices. The NSPs have no dedicated hardware and need to rent from the SCP in term of radio resources, e.g., small cell base stations (SBSs) in order to provide satisfied services to the users. Due to the fact that the selfish parties involved aim at maximizing their own profits, a hierarchical dynamic game framework is presented to address interactive decision problem. In the lower-level, a Stackelberg…
The Effect of the Side Chain on Gelation Properties of Bile Acid Alkyl Amides
2021
Abstract Six bile acid alkyl amide derivatives were studied with respect to their gelation properties. The derivatives were composed of three different bile acids with hexyl or cyclohexyl side chains. The gelation behaviour of all six compounds were studied for 36 solvents with varying polarities. Gelation was observed mainly in aromatic solvents, which is characteristic for bile‐acid‐based low molecular weight gelators. Out of 108 bile acid‐solvent combinations, a total of 44 gel systems were formed, 28 of which from lithocholic acid derivatives, only two from deoxycholic acid derivatives, and 14 from cholic acid derivatives. The majority of the gel systems were formed from bile acids with…

Rod–coil copolymers from oligo(p-benzamide) foldamers
2007
Self assembling rod–coil copolymers were synthesized in which oligo(p-benzamide) rods up to the octamer were prepared via iterative solution synthesis employing the acid labile 2,4-dimethoxybenzyl amide protective group.
Smart City. Una strategia per ri-pensare lo sviluppo urbano sostenibile
La ricerca prende avvio dalle riflessioni sulla crescita della città contemporanea, alla luce del sempre più allarmante sfruttamento delle risorse della natura, criticità che contribuisce al riscaldamento globale. Interrogarsi sulla Smart City è stato un importante punto di riflessione in una fase storica in cui il tema della città intelligente rappresenta una strategia per ri-pensare lo sviluppo urbano sostenibile, partendo da una visione che metta a fattor comune progetti politici, ambientali, economici, sociali e culturali, è fondamentale che le Istituzioni siano messe in grado di attivare processi di medio e lungo periodo e di breve termine che creino le basi fondanti per l’evoluzione e…
Les populations périurbaines face à l'automobile en grande couronne francilienne
2007
The present article is attempting to identify if the automobile, which took part in development of periurban spaces but which causes strong disparities of mobility between households, according to their incomes and of their age, leads to exclude an increasing part of the population in this spaces. We looked more closely into not-motorized population but also motorized households, of modest income or older age, for which cost or physical requirements of automobile mobility are too high. Our results show that number of not-motorized households, most strongly marginalized, decrease in particular in periurban territories most dependent on car, in spite high level of unemployment and ageing of p…
Green growth: regioni italiane a confronto
2015
La ripresa economica e l'interesse verso le problematiche ambientali sono oggetto di studio da parte di molti paesi e organismi internazionali con l'obiettivo di definire un sentiero di sviluppo incentrato su una "crescita verde" (green growth). Economia, ambiente e società sono gli elementi di un sistema che deve necessariamente utilizzare le risorse in maniera efficiente e sostenibile, in modo da garantire che la crescita e il benessere non impoveriscano il patrimonio naturale e questo possa rinnovarsi continuando a fornire nel tempo risorse e servizi ambientali. Scopo del lavoro è quello di analizzare le condizioni regionali che possono favorire una crescita sostenibile. Un'analisi delle…
Latency-Oblivious Distributed Task Scheduling for Mobile Edge Computing
2018
Mobile Edge Computing (MEC) is emerging as one of the effective platforms for offloading the resource- and latency-constrained computational services of modern mobile applications. For latency- and resource-constrained mobile devices, the important issues include: 1) minimize end-to-end service latency; 2) minimize service completion time; 3) high quality-of-service (QoS) requirement to offload the complex computational services. To address the above issues, a latencyoblivious distributed task scheduling scheme is designed in this work to maximize the QoS performance and goodput for the MEC services. Unlike most of the existing works, we consider the latency-oblivious property of different …
Mining Customer Requirement from Helpful Online Reviews
2014
Today there are a huge quantity of online reviews available across different categories of products. The key question is how to select helpful online reviews and what can we learn from the abundant reviews. In this paper, we first conclude five categories of features to predict reviews' helpfulness from the perspective of a product designer and then present an approach based on conjoint analysis to measure customer requirement. The suggested approach are demonstrated using product data from a popular Chinese mobile phone market.
