Transformations organisationnelles au cœur d'Entreprises de Service du Numérique (ESN) performantes : Une étude exploratoire
2022
The aim of our study is to deepen our knowledge of consulting companies in France. We seek, essentially, to understand the organizational characteristics of those who show better performance. We were particularly interested in the case of the IT consulting firm. T herefore, we conducted a series of semi- structured interviews with fourteen consulting experts in France over a period of five months. Our results paint an altered picture of these firms and show an evolving sector over the technological transformations of recent years. These changes are pushing IT consulting firms to rethink their managerial practices and organizational architectures to regain the confidence of consultants and d…
A class of multivariate extreme value distributions with heterogeneous margins
2013
Many problems which involve applications of extreme value theory show an essential multivariate nature and recent development of the theory in this field deal with the construction of multivariate extreme value distributions. Owing to the nature of the problem under examination, extreme values to be analyzed jointly may have different limiting distributions, but it seems that explicit expressions of multivariate extreme value distributions with heterogeneous margins are not present in the literature. In this paper we consider the problem of constructing multivariate extreme value distributions with univariate marginal extreme value distributions not belonging or, more generally, not all bel…
Fusion of technology management and financing management - Amazon's transformative endeavor by orchestrating techno-financing systems
2020
Amazon became the world R&D leader in 2017 by rapidly increasing R&D investment. Its R&D investment in 2017 was double that of 2015, 5 times that of 2012, and 10 times that of 2011. This rapid increase continued in 2018, and Amazon accomplished a skyrocketing increase in its market capitalization, closing to being the world's biggest company. Such a rapid increase in R&D and subsequent market value has raised questions about how to conduct R&D and secure a large amount of funds needed for high-risk investments. Amazon has provided hypothetical answers to both of these questions. Amazon has been conducting innovative R&D to transform routine or periodic alterations into significant improveme…
Institutional systems inducing R&D in Amazon- the role of an investor surplus toward stakeholder capitalization
2020
Abstract Amazon demonstrated a conspicuous increase in R&D and became the world's top R&D firm in 2017 with a skyrocketing increase in market capitalization, making it close to being the world's biggest company. Such a remarkable accomplishment can be attributed to Amazon's institutional systems, which orchestrate techno-financing systems that fuse a unique R&D transformation system and a sophisticated financing system centered on the cash conversion cycle (CCC). These institutional systems support and endorse aggressive investment in R&D that incorporates the characteristics of uncertainty, a long lead time, and successive inflows of very large amounts of funding without interruption. Whil…
Value creation in the international public procurement market: In search of springbok firms
2019
Abstract Public procurement accounts for more than 10% of global GDP. Digital transformation of public procurement creates new opportunities for value creation in international markets. Identifying and analyzing the companies, especially the SMEs, that can capitalize on these opportunities is therefore an important issue for policymaking, management, and scientific research. This study linked microdata on selected bidders from the Tenders Electronic Daily (TED) e-procurement portal and the Orbis database. Based on a sample of 933 Spanish companies, the analysis provides empirical support for the cross-border size bias conjecture. The reason for this bias is the predominance of large compani…
A new design of H ∞ filtering for continuous-time Markovian jump systems with time-varying delay and partially accessible mode information
2013
In this paper, the delay-dependent H"~ filtering problem for a class of continuous-time Markovian jump linear systems with time-varying delay and partially accessible mode information is investigated by an indirect approach. The generality lies in that the systems under consideration are subject to a Markov stochastic process with exactly known and partially unknown transition rates. By utilizing the model transformation idea, an input-output approach is employed to transform the time-delayed filtering error system into a feedback interconnection formulation. Invoking the results from the scaled small gain theorem, an improved version of bounded real lemma is obtained based on a Markovian L…
Robust Assembly Assistance Using Informed Tree Search with Markov Chains
2022
Manual work accounts for one of the largest workgroups in the European manufacturing sector, and improving the training capacity, quality, and speed brings significant competitive benefits to companies. In this context, this paper presents an informed tree search on top of a Markov chain that suggests possible next assembly steps as a key component of an innovative assembly training station for manual operations. The goal of the next step suggestions is to provide support to inexperienced workers or to assist experienced workers by providing choices for the next assembly step in an automated manner without the involvement of a human trainer on site. Data stemming from 179 experiment partici…
Segmented Thermoelectric Oxide-Based Module for High-Temperature Waste Heat Harvesting
2015
We report a high-performance thermoelectric (TE) oxide-based module using the segmentation of half-Heusler Ti_(0.3)Zr_(0.35)Hf_(0.35)CoSb_(0.8)Sn_(0.2) and misfit-layered cobaltite Ca_3Co_4O_(9+δ) as the p-leg and 2 % Al-doped ZnO as the n-leg. The maximum output power of a 4-couple segmented module at ΔT=700 K attains a value of approximately 6.5 kW m^(−2), which is three times higher than that of the best reported non-segmented oxide module. The TE properties of individual legs, as well as the interfacial contact resistances, were characterized as a function of temperature. Numerical modeling was used to predict the efficiency and to evaluate the influence of the electrical and thermal lo…
Shape memory NiTi thin films deposited at low temperature
1999
Abstract NiTi shape memory alloy (SMA) thin films have the potential to become high performance actuators for micro-electromechanical systems. Low temperature crystallized NiTi films would ensure a good compatibility with microelectronic processes and polymers. To avoid the drawbacks induced by annealing, we have tried to obtain low temperature crystallized RF sputtered NiTi films by optimising deposition parameters. We have found that NiTi films containing an excess of Ti (∼52%) were crystallized when deposited on Si(100) substrates heated up to only 473 K. NiTi/Si(n) Schottky diodes I–V characteristics showed a temperature dependence indicating structural transition in the NiTi electrode.…
