Final Reflections: Connectivity, Innovation, Transformation, and Global Challenges

2020

Despite the beginning of the trade war between China and the U.S. in 2018, and despite Huawei’s competitive disadvantages in its globalization process, such as being a latecomer in the market, lack of technological leadership, and liability of foreignness with a negative country of origin image, within 30 years, Huawei managed to become a leading global provider of information and communications technology. Lattemann et al. summarize the discussions in the edited book on Huawei goes Global—with Vol. II studying the question how Huawei overcomes these challenges stemming from the institutional distances between China and the host country they are operating in. The authors show how latest Int…

Ultimate Order Statistics-Based Prototype Reduction Schemes

2013

Published version of a chapter in the book: AI 2013: Advances in Artificial Intelligence. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-319-03680-9_42 The objective of Prototype Reduction Schemes (PRSs) and Border Identification (BI) algorithms is to reduce the number of training vectors, while simultaneously attempting to guarantee that the classifier built on the reduced design set performs as well, or nearly as well, as the classifier built on the original design set. In this paper, we shall push the limit on the field of PRSs to see if we can obtain a classification accuracy comparable to the optimal, by condensing the information in the data set into a single tr…

Impact of e-government on transaction cost and FDI inflows: A proposed conceptual framework

2011

Published version of an article in International Journal of Business and Management, 6(11), 285-296. Also available from the publisher at http://dx.doi.org/10.5539/ijbm.v6n11p285 Although vast normative e-government literature supports the assertion that implementation of e-government reduces transaction cost and promotes Foreign Direct Investment; empirical evidence to support this thesis is limited. Even more, there is limited attempt when studying this phenomenon to integrate e-government literature with other literatures in which major constructs of interest are rooted. This article contributes to reducing this gap by establishing a conceptual framework that integrates e-government lite…

E-Government in Marketing a Country: A Strategy for Reducing Transaction Cost of Doing Business in Tanzania

2011

Published version of an article in International Journal of Marketing Studies, 3(4), 2-16. Also available from the publisher at http://dx.doi.org/10.5539/ijms.v3n4p2 There are limited studies examining the role of Investment Promotion Agencies (IPA’s) and their respective marketing techniques used in attracting Foreign Direct Investment (FDI). Using an exploratory case study approach, this article addresses this research gap by exploring the role of e-government as a promotion technique in eliminating barriers to FDI inflows in Tanzania; particularly barriers related to information accessibility and bureaucratic procedures facing foreign investors in acquiring relevant licenses and business…

Indexing Method for Transitive Relationships of Product Information

2008

To successfully use a relational database management system (RDBMS) as a repository for product information, the RDBMS must efficiently process and properly answer ontological queries. The key to processing the ontological queries is whether the various semantic relationships among the concepts of the product ontology are likewise well-processed. In particular, the transitive relationships (e.g., is-a, component-of relationships) such as ancestors-descendents, parents-children, and taxonomy of products must be processed successfully. We propose an efficient index using a numbering scheme (labeling scheme) to process queries over transitive relationships. (This paper is an extended version o…

UAV-Aided Multi-Antenna Covert Communication Against Multiple Wardens

2021

In this paper, we propose a UAV-aided covert communication scheme assisted by a multi-antenna jammer to maximize the transmission rate between a ground transmitter and a UAV receiver against several randomly distributed wardens. The transmitter adopts the maximum ratio transmission, while the jammer zero-forces its transmitted signal at the UAV to disturb the monitoring at wardens without interfering the legitimate transmission. First, we analyze the detection performance and derive the optimal threshold for each warden to minimize its detection outage probability (DOP). Then, with the worst situation in which all wardens set their respective optimal thresholds to achieve the minimum global…

Enabling Backoff and Eliminating Redundant Idle Period for Medium Access in LTE-U

2017

To address the burgeoning demand for mobile data, 3GPP is actively studying the capability of operating LTE in the unlicensed band, referred to as LTE-U. One of the main challenges of this approach is to maintain better coexistence between WiFi and LTE-U devices. To enable the coexistence, the listen before talk (LBT) principle has been adopted for LTE-U medium access with two flavors of mechanisms, i.e., load based equipment (LBE) and frame based equipment (FBE) access. In this paper, we consider the FBE mechanism and enhance its performance by introducing a backoff procedure for LTE devices. We investigate the original FBE mechanism defined by 3GPP and the enhanced FBE (E- FBE) mechanism fr…

Use of ICT in Smart Cities. A practical case applied to traffic management in the city of Valencia

2015

The whole process of converting a city into the new concept of Smart City implies the improvement of the efficiency and quality of services made available by governments and businesses and a corresponding increase in citizens' quality of life.

Applications of ARTIST for advanced telematics services

2007

This paper describes how telematics, also known as Information and Communications Technology (ICT), integrates telecommunications and informatics technologies to send, receive and store information via telecommunication devices. The Intelligent Transport System (ITS) is the application of telematics to the transportation area so that it allows the provision of advanced services in the mobility area in order to reinforce the efficiency, safety and effectiveness of the transportation systems. More efforts have been carried out in recent years to support the spreading of ITS and many projects have been financed in the world and, in particular, in Europe. One of the most critical problems which…
