Digital individual benefit statement ::the use of a triangulation methodology to design a digital platform for Switzerland

Old age retirement pensions are an important concern among the Swiss but estimating one’s income after retirement is difficult due to the Swiss insurance system’s complexity. This project’s aim is to prepare for developing a digital platform that will allow individuals to plan for retirement in a simplified manner. The main objective of the platform will be togive individuals the…

Dismissing poisoned digital evidence from blockchain of custody

This paper presents a solution to dismiss a digital evidence from a permissioned blockchain-based legal system, serving as evidence chain of custody. When challenged into court, a digital evidence can be entirely dismissed, as well as all the procedural acts originating from this evidence, including personal gathered data. Since a blockchain, by design, cannot be altered, this paper…

PLC hacking on sea vessels

This paper presents a case of alleged PLC (Programmable Logic controller) hacking aboard a commercial ship, and the forensic investigation of PLC components. It presents the lessons drawn from this case and the particular difficulty of investigating PLC and SCADA systems onboard. Whereas hacking is often seen as taking control of a ship, or part of a ship, it is also related to the…

Optimal design of e-service ::a robust approach

Service design optimizers benefited greatly from the development of conjoint analysis, which appeared more than forty years ago. Conjoint analysis is a powerful and popular method to estimate consumers’ preferences. As this method is based on a survey, the estimated utility functions can be subject to inaccuracies. In this paper, we propose a service design optimizer that combines…

Evaluation of forecasting approaches using hybrid multicriteria decision-making models

The demand forecast is the most influential input into enterprise activities planning thus creating a challenging issue for Demand Planning experts in model selection. Models including quantitative, qualitative and hybrid forecasting methods have been developed and are widely used. The literature reveals the use of several case-dependent error measures to evaluate forecasting…

Large-scale nonlinear variable selection via kernel random features

We propose a new method for input variable selection in nonlinear regression. The method is embedded into a kernel regression machine that can model general nonlinear functions, not being a priori limited to additive models. This is the first kernel-based variable selec- tion method applicable to large datasets. It sidesteps the typical poor scaling properties of kernel methods by…

Estate fiscal policies, long-term care insurance and informal care

This paper studies the effects of estate recovery, estate taxation and long-term care (LTC) subsidies on the incentives both to buy LTC insurance and to transfer wealth by elderly parents and to provide informal care by children to their dependent elderly parents. We also investigate the effect of these three fiscal policies on public budgets allocated to finance LTC needs. Estate…

Training, consulting and teaching for sustainable approach for developing research data life-cycle management expertise in Switzerland

Developing research in different fields is defendable as well as necessary for the development of disciplines and knowledge construction in general. The progress of qualitative and quantitative approaches is based on hard competitiveness and high level of innovation. This increases the need of a rigorous management of research process which should be more and more accurate and…

Management accounting and control practices ::qualitative research of Swiss industries using enterprise resources and planning systems

Based on qualitative research that was conducted on enterprises from the industrial sector, we acquired new knowledge on the use and the needs of management accounting and control practices. The focus of the study was small and middle industries based in the French-speaking part of Switzerland using an ERP (Enterprise Resources Planning) system. The research aims to highlight the…

Weighted forensics evidence using blockchain

When digital evidence is presented in front of a court of law, it is seldom associated with a scientific evaluation of its relevance, or significance. When experts are challenged about the validity of the digital evidence, the general answer is “yes, to a reasonable degree of scientific certainty”. Which means all and nothing at the same time, since no scientific metric is…

A least-squares/relaxation method for the numerical solution of the three-dimensional elliptic Monge–Ampère equation

In this article, we address the numerical solution of the Dirichlet problem for the three-dimensional elliptic Monge–Ampère equation using a least-squares/relaxation approach. The relaxation algorithm allows the decoupling of the differential operators from the nonlinearities. Dedicated numerical solvers are derived for the efficient solution of the local optimization problems with…

Ontological model of competence management

Dans cet article, nous proposons une nouvelle approche concernant le modèle ontologique de la compétence basé sur la roue de Deming afin de faciliter la communication et la compréhension de l'information qui assure une bonne gestion des ressources au sein de l'entreprise. Nous choisissons l'ontologie car elle permet de définir et de gérer les compétences et les…

Program understanding using ontologies and dynamic analysis

No maintenance activity can be performed without understanding at least the part of the program that needs to b emodified. Therefore, considering its cost, helping developers to understand programs is a must. Consequently, our research aims at building a business related model of the program semantics, which is grounded in Perkinsfi research in psychology. After a short reminder of…

Operational route choice methodologies for practical applications

This paper focuses on the application of tractable route choice models and presents a set of methods for deriving relevant disaggregate and aggregate route choice indicators, namely link and route flows. Tractability is achieved at the disaggregate level by the recursive logit model and at the aggregate level by the mental representation item (MRI) approach. These two approaches are…

Train timetable design under elastic passenger demand

A passenger centric timetable is such a timetable that the satisfaction of the passengers is maximized. However, these timetables only maximize the probability of a passenger to take the train, but provide no insight on the actual choices of the passengers. Therefore, in this manuscript we replace the deterministic passenger satisfaction function with a probabilistic demand…

The feasibility of equilibria in large ecosystems: a primary but neglected concept in the complexity-stability debate

The consensus that complexity begets stability in ecosystems was challenged in the seventies, a result recently extended to ecologically-inspired networks. The approaches assume the existence of a feasible equilibrium, i.e. with positive abundances. However, this key assumption has not been tested. We provide analytical results complemented by simulations which show that equilibrium…
