Do So

This paper aims to assess the maturity level of competitive intelligence (CI) in Moroccan companies, so as to improve theirs practices, and to justify their investment in competitive intelligence. To do so, we have identified the maturity model based on a comprehensive review of recent literature. The objectives of this paper are threefold: (1) to determine the major purposes of a CI maturity model (CIMM), (2) to identify the types of CI dimensions and levels of maturity, (3) to evaluate Moroccan companies in terms of CI practice. Our approach is to develop a conceptual framework of the CI maturity model that articulates (1) dimensions of CI, and (2) maturity levels of CI. We note that little attention has been given in previous research to how CI is actually conducted in Moroccan companies. For this purpose, an empirical study was conducted. The results discuss various perspectives and insights from a competitive intelligence maturity model point of view in the Moroccan context. The results show that the majority of the Moroccan companies are in an early stage of the CI levels, where the CI practice is only to employ environment scanning and the competition in the business environment is not intense. We also note the absence of CI structure at this level. Most of these Moroccan companies are not able to cope with changes in the business environment. The CI systems and processes are released on an irregular basis. This study is the first to investigate the Competitive Intelligence Maturity Model (CIMM) in the Moroccan context. The findings of this research show that there are six CI dimensions (CI culture of an organization; CI deliverables; CI sourcing; CI cycle; CI investment in terms of resources; CI users and CI application) that should be taken into account in CI implementation with regard to the CI level (early, mid, world class).

Successful Design

An integrated system consisting of two towed sub-sea vehicles and a free-floating probe is being developed to perform mapping and quantitative estimations for fish and plankton. A thorough understanding of the dynamic behaviour of the towed vehicle system is essential for a successful design, and a dynamic model that can accurately describe the vehicle behaviour under the influence of a wide variation of conditions, is necessary. This paper discusses two different approaches for the dynamic analysis of a towed vehicle system. Analyses are performed using the commercial available simulation program MOSES. Further the 2D equations of motion for the towed vehicle are developed and solved in Matlab using a simple cable model.

Fast-charging infrastructure with charging time of 20–30 min can help minimizing current perceived limitations of electric vehicles, especially considering the unbalanced and incomprehensive distribution of charging options combined with a long perceived charging time. Positioned on optimal location from user and business perspective, the technology is assumed to help increasing the usage of an electric vehicle (EV). Considering the user perspectives, current and potential EV users were interviewed in two different surveys about optimal fast-charging locations depending on travel purposes and relevant location criteria. The obtained results show that customers prefer to rather charge at origins and destinations than during the trip. For longer distances, charging locations on axes with attractive points of interest are also considered as optimal. From the business model point of view, fast-charging stations at destinations are controversial. The expensive infrastructure and the therefore needed large number of charging sessions are in conflict with the comparatively time consuming stay.

We determine the dynamics of the total state of a system and environment for an open system model, at finite temperature. Based on a partial Husimi representation, our framework describes the full dynamics very efficiently through equations in the Hilbert space of the open system only. We briefly review the zero-temperature case and present the corresponding new finite temperature theory, within the usual Born-Markov approximation. As we will show, from a reduced point of view, our approach amounts to the derivation of a stochastic Schrödinger equation description of the dynamics. We show how the reduced density operator evolves according to the expected (finite temperature) master equation of Lindblad form.

A method of designing controllers for multivariable systems is described which regards the problem from an implicit reference model point of view. The rules for the design are found to be very simple to apply and involve only proportional and integral terms if all the system state variables are available. The method is demonstrated by means of two examples, one being a second order system with two inputs and two outputs, the other being a fourth order system also with two inputs and two outputs.

We studied cluster structures formed in two- and three-dimensional magnetic fluid systems numerically. We developed a Brownian dynamics calculation method in which both the translational and rotational motions of ferromagnetic particles were taken into account. The cluster formations are analysed from the point of view of second order phase transition and the dependence of the cluster size on the temperature and magnetic field is investigated. The fractal dimensions were, respectively, 1.3 and 1.6 for the two- and three-dimensional systems in the absence of a magnetic field. On the other hand, the fractal dimension was very close to 1.0 for both two- and three-dimensional systems when the system was subjected to a magnetic field. The cluster-cluster aggregations are also investigated and the validity of the dynamic scaling law is examined. It has been found that the fractal dimensions obtained by the dynamic analysis coincide with those obtained by the analysis of the cluster structures. The critical exponents were 0.7 and 0.8 in the absence of a magnetic field and in a magnetic field, respectively, in the case of the two-dimensional system, and 1.2 and 0.8 in the case of the three-dimensional system for λ=12 where λ is the ratio of magnetic dipole energy to thermal energy.

The paper presents an analytical method of identifying the curvature of the turnout diverging track consisting of sections of varying curvature. Such turnout is mainly applied on High Speed Railway. Both linear and nonlinear (polynomial) curvatures of the turnout diverging track are considered in the paper. Obtained solutions enable to assume curvature values at the beginning and end point of the geometrical layout of the turnout.The paper focus on a fundamental and unexplained so far issue connected with selection of the most favourable curvature section from the operational requirements point of view. In order to determine the optimal curvature a dynamic analysis has been carried out on the several representative cases. It has been indicated that, used in railway practice, clothoid sections with nonzero curvatures at the beginning and end points of the turnout should be verified. It has been proved that the turnout with nonlinear curvature reaching zero values at the extreme points of the geometrical layout is the most favourable.
