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...

A digital individual benefit statement to mitigate the risk of poverty in retirement ::the case of Switzerland

Old-age retirement benefits are a major concern among the Swiss population but estimating one’s revenue after retirement is challenging due to the Swiss social system’s complexity. In Switzerland, as with many other countries, the risk of poverty for retiree people is high, especially for women who often work part-time. The research presented in this paper proposes a methodology to...

A robust share-of-choice model

In this paper, we propose an approach to take into account , in a robust way, part-worth uncertainty in a share-of-choice (SOC) model. More precisely, we extend the method proposed by Wang and Curry by endogenously including competition. Indeed in their approach, competition is described exogenously and the model cannot take into account part-worth uncertainty for the competition’s...

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...

Least-squares/relaxation method for the numerical solution of a 2D Pucci’s equation

The numerical solution of the Dirichlet problem for an elliptic Pucci’s equation in two dimensions of space is addressed by using a least-squares approach. The algorithm relies on an iterative relaxation method that decouples a variational linear elliptic PDE problem from the local nonlinearities. The approximation method relies on mixed low order finite element methods. The least-...

Security governance as a service on the cloud

Small companies need help to detect and to respond to increasing security related threats. This paper presents a cloud service that automates processes that make checks for such threats, implement mitigating procedures, and generally instructs client companies on the steps to take. For instance, a process that automates the search for leaked credentials on the Dark Web will, in the...

Blockchain-based digital evidence inventory

This paper proposes the use of a blockchainbased structure in order to store evidences in a digital forensics investigation. The traditional chain of evidence is augmented with properties of immutability and traceability, thanks to a cryptographic process. The blockchain is constructed by forensics experts by adding evidences through the process. Since the blockchain is immutable, it...

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...

A supply-demand modeling of the Swiss roundwood market ::actors responsiveness and CO2 implications

Given the importance of wood products in CO2 sequestration, an increase in the use of local wood in construction may help reduce the sector's net emissions. However, given the low prices of wood, the Swiss forest industry is unwilling to produce more, despite the important potential of wood mobilization. Financial incentives may help meet the goals of both environmental and...

A hedonic approach to estimate the price of reliability, energy efficiency and safety for new cars in Switzerland

When purchasing a car in Switzerland, consumers can consult three quality labels. First, a reliability label provides the probability that a given car will have a breakdown in the next year. Second, an energy efficiency label, based on fuel consumption and carbon dioxide emissions, ranks cars from A to G. Third, a safety label, based on crash tests, ranks cars from five to one stars...

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...

Biomedical ontology alignment ::an approach based on representation learning

Background: While representation learning techniques have shown great promise in application to a number of different NLP tasks, they have had little impact on the problem of ontology matching. Unlike past work that has focused on feature engineering, we present a novel representation learning approach that is tailored to the ontology matching task. Our approach is based on embedding...

The CoWaBoo protocol and applications ::towards the learnable social semantic web

Web platforms and applications are generating a normalized environment for users to consume information. This process of making the Internet experience “clickable” and “fun” comes at a price: we are less inclined to face important decisions on how applications work, data are handled, or how algorithms decide. This article will examine the possibility of shifting from predetermined...
