In fact, this model consists of images of the actual and forthcoming situation of the upcoming space flight, formed on the basis of information surplus and multiple models, more or less adequate to the situation. In this regard, the article proposes an experimental methodology to develop a conceptual model and study of basic human mental models as a control system in case of perception, accumulation and processing information and knowledge, making decisions and performing control activities in extreme conditions. A discussion is held about the possibilities of applying the technology of virtual reality \VR\ application in modeling and testing the man as a control system.

The purpose is to increase the interaction length or the optical nonlinearity, respectively. These two effects can be implemented simultaneously by use of quantum confined structures (for example — semiconductor-doped glasses) in waveguide geometry. In this contribution we consider the effect of wave and charge confinement on fifth-order nonlinearities in semiconductor-doped optical fibers and briefly discuss some resulting physical phenomena such as quasi-soliton pulse propagation and bistability. If we consider a nonlinearity [1] of saturation type and the electron and hole motions are completely decoupled, then the ls-ls transition is isolated enough and each crystallite behaves as an ideal two-level system that may be bleached at the same frequency “ that is resonant with the transition frequency ” 1s , and thus contribute to the degenerate nonlinear optical susceptibility χ(5)(ω, — ω,ω,- ω,ω). Recently a way was proposed [2] for increasing essentially the contribution of the fifth-order nonlinearity in semiconductor doped fibers: doping the fiber with two appropriate materials, both having a saturable nonlinearity. The refractive index change law of both dopands is assumed to be of Kerr type with saturation intensities I s1 » I S2 and nearly the same values for the nonlinear refractive index coefficients. Then, in a regime far from saturation, the refractive index of the fiber takes the form {fy(1)|311-1}

In this chapter, we present the finite-difference time-domain (FDTD) method [1–6] that can be used to calculate light scattering by arbitrary particles and surfaces. The FDTD technique is a numerical solution to Maxwell’s equations and is formulated by replacing temporal and spatial derivatives in Maxwell’s equations with their finite-difference equivalences. This method can be accurately applied to general electromagnetic structures including arbitrary particles and surfaces. The FDTD technique has been successfully applied to calculate light scattering and absorption by particles of different shapes in free space [5] and in absorbing medium [6]. Recently, an advanced FDTD model to calculate the interaction of electromagnetic radiation with arbitrary dielectric surfaces has been developed [7]. In the following sections, these FDTD light-scattering models are reviewed.

This month features the first two of several papers in upcoming issues from the 31st ISPIM Innovation Conference, which had the theme "Innovating in Times of Crisis", and was held virtually on June 7-8th, 2020. Our ongoing cooperation with the International Society for Professional Innovation Management offers the opportunity for the Editorial Board to select highly relevant articles in particular research domains and invite submissions that undergo the usual double blinded peer review process resulting in the selection of high quality contributions of interest to our readers. Three other papers add further contributions based on current research focusing on the strategic aspects of business intelligence, smarter cities, and the social acceptance of cleaner energy.

Many firms are in the process of shifting their focus from offering standalone products or services towards integrated offerings of products and services to meet specific customer demands, thus generating additional value. This paper examines technology-based start-ups’ attitude towards the development of hybrid offerings as part of their business differentiation and positioning strategies. The main research question is answered within the context of Danish technology-based start-up firms by adopting a case study based qualitative research approach. Five explorative case studies, of in total four different start-ups and one larger firm used as reference case, have been composed to examine the challenges associated with the development of product-enabled services as part of an integrated value proposition. The research find...

In the current paper we use both traditional attributes of group entities and network constructs in order to examine what makes small project management teams to cooperate in order to develop effective value propositions. Our research has investigated a number of group attributes and relationships within members and how their corresponding network measures are correlated with the effectiveness of 17 final year student teams working towards their final year group project. Network measures like cohesion and centrality that are meaningful for small groups have been calculated on all relationships between group members. In addition to traditional attributes like size and sex ratio, the research team has developed a new attribute called group diversity as a measure of the inverse in similarity o...

According to the notion of co-creation, if a user or customer is involved in the design or production of a product or service, the end value will be enhanced for both, the customers and the firm, because of the opportunity for customers to creatively contribute to the design and innovation processes by tailoring the product according to their own personal visions. 2 Co-creation therefore refers to collaboration with customers for the purposes of innovation. 3 Even though the end user is the ultimate destination of the value creation process, the interaction between designers/innovators and end users is not merely a bi-directional process since it incorporates the contingency of the activities performed by the different actors contributing to the emergence of customer value. The conceptualization of the contingent nature and the multiplicity of agency as well as the emergent nature of customer value have created challenges for design and innovation researchers requiring a deeper and more symmetrical understanding of the interaction between designers, innovators, customers and end users. As result, there is a need for a better understanding of the

The field of project management is directly related with project success. At least for five decades the project evaluation was determined by meeting three criteria (time, cost, quality). Many researchers suggest that success can’t be accessed only through the three criteria, since project success is more complex. Do the owner, developer, contractor, user, general public see the project with the same dimensions of success? The success criteria vary from project to project since we have different types with different people. In project assessment we may need a multidimensional approach due to project complexity differences that will also take under consideration the project effectiveness variables. The paper reviews the appropriate management models that include key elements of measuring project success and project effectiveness that can both be outcomes in a project.
