There are three kind of losses in transmission lines: ohmic, dielectric and radiation losses. While the first two are local phenomena which are easy to model, the radiation losses lack a simple model. This is because the radiation is a global process, determined by the constructive interference in the far field of the individual contributions, rather than the local behavior of the current. The aim of the current work is to analyze the radiation process from transmission lines, aiming to find some possible radiation model. © 2016 EuMA.

The objective of this research is to create a model for exploring practices and management interventions that can concurrently influence an organizational effectiveness, the quality of its culture and employee health. These three dimensions collectively determine, to some degree, an organization's long-term sustainability. A qualitative dynamic modeling representation is used to capture the interrelationships among these three dimensions and to explore key feedback structures discussed in the literature and which may exist within an organization. The modeling indicated linkages among the three dimensions and many others, and their potential for effecting organizational change. Dynamic hypotheses were formulated based on literature from the fields of management, engineering, social systems and organizational psychology. A field study of an actual organization confirmed these hypotheses and indicated greater dynamic complexity than what may be inferred from the literature. © 2016 Portland International Conference on Management of Engineering and Technology, Inc.

The design thinking approach which shapes the design culture of many organizations today, focuses on users’ experiences, particularly their emotional ones, and strives to develop smart technologies and other complex systems and make them simple, intuitive and pleasurable. During design thinking processes, development teams are required to build empathy with users, observe their behavior and conclude and describe what they want and need, by using emotional language such as desire, love and aspire. Moreover, emotional attributes and notations are inserted into current modeling languages for expressing emotional goals and motivations for realizing users’ perceptions of systems. For fostering design thinking capabilities, universities offer multidisciplinary learning opportunities where engineers and designers learn and practice together design thinking in development processes. In this regard, Shenkar, College of Engineering, Design and Art, provides students with several multidisciplinary learning opportunities in courses and workshops. This paper reports on these opportunities and brings insights and recommendations for enhancing the next multidisciplinary teaching events. The recommendations draw on the current body of literature in the areas of design thinking approach, agile framework and creativity, and address: defining open challenges that appeal to each discipline; handling teams’ working process and responsibilities; and outlining expected solution that encompasses multidisciplinary capabilities. © Springer International Publishing AG 2017.

In this theoretical report, we explore small deformations of an initially spherical drop subjected to uniaxial or biaxial nonlinear extensional creeping flows. The problem is governed by the capillary number (Ca), the viscosity ratio (λ), and the nonlinear intensity of the flow (E). When the extensional flow is linear (E = 0), the familiar internal circulations are obtained and the same is true with E > 0, except that the external and internal flow rates increase with increasing E. If E < 0, the external flow consists of some unconnected regions leading to the same number of internal circulations (-3/7 < E < 0) or twice the number of internal circulations (E < -3/7), when compared to the linear case. The shape of the deformed drop is represented in terms of a modified Taylor deformation parameter, and the conditions for the breakup of the drop by a center pinching mechanism are also established. When the flow is linear (E = 0), the literature predicts prolate spheroidal drops for uniaxial flows (Ca > 0) and oblate spheroidal drops for biaxial flows (Ca < 0). For the same |Ca|, if E > 0, the drop is more elongated than the linear case, while E < 0 results in less elongated drops than the linear case. Compared to the linear case, for both uniaxial and biaxial extensional flows, E > 0 tends to facilitate drop breakup, while E < 0 makes drop breakup more difficult.

Nowadays, customers purchase habits have changed: they do not buy more goods or services in the traditional sense, perceiving them as two separated entities. They rather look for a solution, whose value encompasses many intertwined components, some of them being services and some being goods. In this context, the Product-Service System (PSS) concept finds its root. The servitization process of a product manufacturer into a provider of a PSS still constitutes a major managerial challenge. This challenge is based on a new kind of solution, which considers the continuum between services and products, where services represent a key element for gaining competitiveness. Theoretical and practical experiences show that servitization pushes organisations to change their strategies, operations and value chain, technologies, people expertise and system integration capabilities. As a consequence, different competences are requested to be analysed to have a complete vision of the PSS phenomenon. An international interdisciplinary working group is important to fulfil the need to provide a complete vision of the PSS. Due to the vastness of the area, it is relevant to bring together, in the context of a collaborative scheme of research exchanges, the reciprocal knowledge of the partners. The project proposal links 10 members: 4 EU, 2 AC, and 4 third country partners, which have agreed for a common exchange program on the analysis of the Product-Service System across Life Cycle. The exchange program aims to facilitate the deployment of a collaborative scheme focused on the exchange of the knowledge required to develop new models/methods/ICT tools to support the PSS across all its Life Cycle phases. Each member provides complementary knowledge on the field. The project will concern the exchange of a set of various activities of PhD students, researchers and professors. The planned exchange scheme will enable the reciprocal transfer of knowledge between the members.

Steady and unsteady mass transfer in the continuous phase around slightly deformed oblate spheroidal drops at low (but not zero) Reynolds numbers was investigated theoretically. Asymptotic analytical solutions for short and long times, at large Peclet numbers, were obtained by the useful equations derived by Lochiel and Calderbank and by Favelukis and Mudunuri for axisymmetric drops of revolution, with the only requirements being the shape of the drop and the tangential velocity at the surface of the drop. As expected, the result, although complicated, represents a small correction to the classical problem of mass transfer around a spherical drop under creeping flow conditions, since the physical problem presented here requires both the Reynolds and the Weber number to be much smaller than one. © 2010 Elsevier Ltd.

The major indigoids constituting modern and archaeological purple pigments produced from molluskan species include, in varying compositions, indigo, 6-bromoindigo, and 6,6′-dibromoindigo. Though woolen Tyrian Purple dyeings produced from these pigments were the most prized and precious of all dyeings in antiquity, a full chromatographic and colorimetric analysis of multi-fibered textiles dyed with these indigoids has not been previously performed. This current study reports on high-performance liquid chromatographic (HPLC) analyses conducted on the indigoid pigments and on woolen dyeings individually produced from them. In addition, comparative colorimetric analyses via reflectance spectrophotometry were performed on standard multifiber fabric swatches, each consisting of 13 different synthetic and natural fibrous materials. Each swatch was dyed with one of the cited indigoids. These colorimetric properties included the Kubelka-Munk spectral curves, color strengths at the wavelengths of maximum absorptions, color coordinates of the CIE L*a*b* and L*C*h* color spaces, and the color differences. Excellent functional correlations were observed among these properties and these relationships should be applicable to similar dyeings on other fabric materials. The results show that filament triacetate and nylon-66 possess the most remarkable color strengths of all the fiber materials investigated in all the dyeings, and of the natural fibers studied, wool possessed the highest color strength and cotton the poorest with all three dyes. Such chromatographic and colorimetric analyses would further our understanding of the colors produced from ancient, and modern, purple-dyed textiles. © 2012 Elsevier Ltd. All rights reserved.

Business Intelligence (BI) systems are applied by increasing numbers of organizations in a wide range of sectors. Despite the growing numbers of BI solutions and the experience augmented in many implementation projects worldwide, as well as the value that BI systems provide to organizations, IT literature lacks a coherent set of definitions through which BI systems can be classified, categorized, and assessed. Furthermore, BI implementation projects often do not succeed or do not fully accomplish the degrees of value and performance as expected, when firms fail to complete the system implementation, to satisfy the needs of users or when the benefits BI systems produce are lower than anticipated. This paper presents an analytical framework through which BI systems are defined and classified. On the basis of this framework, possible technical, organizational, and personal factors that affect the failure, partial or full success of BI system implementations are discussed. These factors are followed by a case study and empirical data analyses that exemplify and assess the extent to which various organizational attributes and properties of users influence the success or failure of BI implementation projects. Finally, implications regarding the management of BI system implementation projects and the organizations that apply them are derived. Copyright © 2012, IGI Global.

A photovoltaic device is presented including one or more cell units. The photovoltaic device comprises a semiconductor substrate having a patterned light collecting surface defining an array of spaced-apart substantially parallel first grooves. Each of these first grooves has a bottom portion, comprising a bottom surface and side walls extending from the bottom portion and being substantially perpendicular to the surface of the device. A heavily doped semiconductor layer in the form of spaced-apart regions is located at the bottom surfaces of the first grooves respectively. Further improvement of performance is obtained by deposition of thin metal lines on top of the heavily doped spaced apart lines.
