Technology and market conditions toward a new competitive landscape in the wireless access market
(2010)This article argues that the wireless telecommunication market is about to witness a shift in business models and market structure as a result of the deployment of new broadband access technologies, spectrum management ... -
Prediction of RFID performance in supply chains
(2010)This paper discusses the challenges to wide-spread radio frequency identification (RFID) adoption in supply chains using the technology s-curve and the concept of buying hierarchy. A survey on RFID uptake in New Zealand ... -
Organizational management for innovation: Petrochemical sector case in Cartagena de Indias (Colombia)
(2010)This study was made within the framework of characterizing the petrochemical and plastic sector and aims to analyze different models of organizational management for innovation. The methodology used was that of multiple ... -
An infinite family of relativistic magnetized finite thin disks
(Institute of Physics Publishing, 2011)An infinite family of relativistic finite thin disk model with magnetic field is presented. The model is obtained for solving the Einstein-Maxwell equations for static spacetimes by means of the Horsk-Mitskievitch generating ... -
Stability Analysis of Single-Phase Low-Voltage AC Microgrids with Constant Power Terminals
(Institute of Electrical and Electronics Engineers Inc., 2019)This express brief presents the stability analysis of single-phase microgrids (SP-MG) operating under master-slave connection with constant power terminals. The SP-MG is composed of linear elements, nonlinear loads, and ... -
Analytical solution to the circularity problem in the discounted cash flow valuation framework
(2011)In this paper we propose an analytical solution to the circularity problem between value and cost of capital. Our solution is derived starting from a central principle of finance that relates value today to value, cash ... -
How evolving network access and network management technologies are redefining the competitive wireless markets
(2011)This paper examines some of the key problems users encounter when accessing current generation wireless networks. Using a case study of a hypothetical user, the authors explore the emerging services and the new broadband ... -
Electromagnetic sources distributed on shells in a Schwarzschild background
(2011)In the Introduction we briefly recall our previous results on stationary electromagnetic fields on black hole backgrounds and the use of spin-weighted spherical harmonics. We then discuss static electric and magnetic test ... -
Design of a CMG for underwater robots
(2011)In this paper we present a Control Moment Gyroscope (CMG) for underwater robots. This is a single gimbal CMG with pyramid type configuration. This device has a modular design and is self-contained (i.e., all mechanical and ... -
Steric and chain length effects in the (√(3) × √(3))R30° structures of alkanethiol self-assembled monolayers on Au(111)
(Wiley-VCH Verlag, 2011)The translational and orientational potential energy surfaces (PESs) of n-alkanethiols with up to four carbon atoms are studied for (√(3) × √(3))R30° self-assembled monolayers (SAMs). The PESs indicate that methanethiol ... -
Monopole and dipole layers in curved spacetimes: Formalism and examples
(2011)The discontinuities of electromagnetic test fields generated by general layers of electric and magnetic monopoles and dipoles are investigated in general curved spacetimes. The equivalence of electric currents and magnetic ... -
Wireless passive sensing application using a cavity loaded evanescent mode half mode substrate integrated waveguide resonator
(2011)In this work, an evanescent mode half mode substrate integrated waveguide (HMSIW) resonator is designed for a wireless passive sensing application at 5 GHz. The wireless pressure sensor has been implemented by placing a ... -
Research on energy indexes of cogenerated plants with gas turbines and heat recuperator steam generators
(2012)The main objective of this paper is the experimental investigation of the energy indexes of a cogeneration plant with Gas Turbines (GT) and Heat Recuperator Steam Generators (HRSGs) while changing its operational load. The ... -
Children vaccination programs in latin america, 2000-2015
(Editorial Ciencias Medicas, 2019)Introduction: Coverage of children vaccination programs is associated with the survival probability of infants and it is a measure of the performance of national immunization systems. Objective: To characterize children ... -
Robot based on task-space dynamical model
(2011)This study deals with the dynamic modelling and task space control of the Stewart-Gough platform. The dynamic equations were obtained using the virtual work approach, and include all the 13 presented in the platform, that ... -
Viable business models for M-commerce: The key components
(IGI Global, 2011)As mobile applications increase in popularity, the issue of how to build viable business models for the m-commerce industry is becoming a clear priority for both organizations and researchers. In order to address this ... -
Electrically tunable evanescent mode half-mode substrate-integrated- waveguide resonators
(2012)Electrically tunable evanescent mode half mode substrate integrated waveguide (HMSIW) resonators are implemented for S band applications. An HMSIW loaded with a complementary split ring resonator (CSRR) achieves forward ... -
Differential diagnosis of hemorrhagic fevers using ARTMAP
(Springer Verlag, 2012)The differential diagnosis of endemic hemorrhagic fevers in tropical countries is by no means an easy task for medical practitioners. Several diseases often overlap with others in terms of signs and symptoms, thus making ... -
Economic lot scheduling with deliberated and controlled coproduction
(2012)This paper presents an algorithm to define the optimal parameters for deliberated and controlled coproduction in an economic lot scheduling problem setting (DCCELSP). Coproduction is said to be deliberated and controlled ... -
