    Opis:
    This article analyzes the design and implementation of telecommunications service policies targeted at the poorest regions of Mexico (1990-2008). It begins by defining universal access and service policies, their economic and social rationale. Secondly, it discusses the scope of public policies on universal service provision designed by Mexican authorities to achieve the goal of universal access. Thirdly, the paper analyzes the distributive effects of this set of policies among the poorest sectors of the population. The sources on which this research was based were two national surveys: the Household Income and Expenditure Survey (2008), and the Household Survey of the Access and Use of Information Technologies (2007). The additional information on regional economic development was based on the poverty indexes by the national population council and economic information given by Mexico's Census Bureau. Additional use was made of the annual reports prepared by Ministry of Communications, statistics published by the Federal Telecommunications Commission and official documents prepared by the government agencies. Finally, a series of in-depth interviews was conducted with the former representatives of the Office of Rural Telephony. Finally, the article discusses, in the light of available evidence, possible explanations for the apparent failure of the universal service policy that was implemented to bring at least basic voice services to Mexico's neediest.

    Opis:
    The telecommunications industry in last decade went through the dramatic changes motivated by mobility, wireless technologies and miniaturization. The continuous increase in the complexity and the heterogeneity of healthcare telecommunications infrastructures requires reliable methodology to assess the quality of service provision. This article presents a cost effective methodology to assess the user's perception of quality of service provision utilizing the existing Staffordshire University network by adding a component of measurement to the existing model presented by Walker. This paper offers a cost effective approach to assess the QoS provision within the University campus network, which could be easily adapted to any campus network or healthcare organization in the world.

    Opis:
    In this paper, a general framework for modelling stochastic service curves for communication networks is presented. It connects with each other two approaches to the traffic analysis and performance evaluation of communication systems, namely, the one which is called a deterministic network calculus with its stochastic counterpart. Thereby, it enables to treat any communication traffic in a consistent way. Further, as we show here, it enables also achieving new results. Derivation of the above model is presented in details in this paper. Finally, some hints are given how the method presented in this article could be applied in maritime telecommunications area.

    Opis:
    The European Commission, European Maritime Safety Agency (EMSA) and Member States of the European Union have expanded the scope of operation of the Vessel Traffic Monitoring and Information System (VTMIS). This project was established in accordance with the requirements of the Directive 2002/59/EC of 27 June 2002. Part of these measures are currently implemented in Poland and are co-financed by the European Union (EU) project entitled “National Maritime Safety System – KSBM”. It is implemented with a time delay in two stages: KSBM-I and KSBM-II. KSBM-I was located on the main list of individual projects of the Operational Programme “Infrastructure and Environment” for 2007–2013. The project is realised with the support of EU funds financed in the Priority VII “Environmentally-friendly Transport” under Measure 7.2 “Development of Maritime Transport”. The works were and are based on contracts signed 28.02.2011 (Stage I – KSBN-I) and 20.12.2012 (Stage II – KSBN-II). The first stage involved the purchase and installation of radar, computer and radio equipment and construction of radio communication network. The second was related mainly to the wire communication network. The system covers Polish coastal waters and seaports from Szczecin and Świnouj- ście to the border with the Kaliningrad Region. This paper presents concept of the system and the state of its implementation.

    Opis:
    The United States Secret Service is an American federal law enforcement agency that is part of the U.S. Department of Homeland Security. Until March 1, 2003, the Secret Service was part of the U.S. Department of the Treasury. The Secret Service has two distinct areas of responsibility: (1) Financial Crimes, covering missions such as prevention and investigation of counterfeiting of U.S. currency and U.S. treasury securities, and investigation of major fraud; (2) Protection, which entails ensuring the safety of current and former national leaders and their families, such as the President, former presidents, vice presidents, presidential candidates, visiting heads of state and foreign embassies. Protecting national leaders, visiting heads of state and government, designated sites and National Special Security Events has become more complex with the evolution of conventional and non-conventional weapons and technology. In meeting new challenges, the Secret Service will continue to provide progressive training, devise and implement sound security plans, measures, equipment and systems to ensure the safety of individuals, sites and events under Secret Service protection. The Secret Service’s unique investigative and protective mission is sustained by a strong, multi-tiered infrastructure of science, technology and information systems; administrative, professional and technical expertise; and management systems and processes.
