Study of the modifications needed for effective operation NASTRAN on IBM virtual storage computers

The necessary modifications were determined to make NASTRAN operational under virtual storage operating systems (VS1 and VS2). Suggested changes are presented which will make NASTRAN operate more efficiently under these systems. Estimates of the cost and time involved in design, coding, and implementation of all suggested modifications are included

Telecommunications Divestment: An Erosion of Democracy in the Caribbean

This article examines the undemocratic process of telecommunications divestment in Jamaica and Trin- idad and Tobago. The divestment of the telecommunications sector was largely prompted by each state’s inability to service external debt. Despite espousing the importance of public participation in the ownership of state-owned en- terprises being divested, the governments each limited or excluded nationals from ownership of the telephony com- panies. Divestment of the telecommunications sector was principally undertaken through private negotiations with Cable and Wireless which has historically provided service to former British colonies. This continued colonization of the telecommunications sector is at odds with the democratic structure of both states

Telecommunications Reform In Southern Africa: The Role Of The Southern African Development Community

This article examines telecommunications reform and related infrastructure and service developments in Southern African states. In focusing on this region, the article analyses the role of the Southern African Development Community (SADC) and the different associations and commissions it has created to develop the telecommunications sector and facilitate reform, which is essential to promote network efficiencies and extend the infrastructure to rural areas. As a regional organisation, SADC is poised to promote restructuring of the telecommunications sector in its 14 member states, as it seeks to achieve complementary national and regional programs and promote sustainable development and economic growth through regional integration

Telecommunications Reform In Botswana: a Policy Model for African States

Since the mid-1990s, Botswana has pursued a policy of telecommunications liberalisation. This article, based on fieldwork conducted in Botswana in the summer of 2000, analyzes several notable aspects of the process of reform and denotes those worthy of emulation by other African states. The participation and protection of domestic telecommunication users, transparency in decision-making, the creation of an independent regulatory agency, and the introduction of competition in the form of private cellular service providers are among those policy features that are recommended for replication. Various facets of the tendering process and subsequent licences granted to the mobile operators as well as recent legislation are also examined and commended

Development of a polysilicon process based on chemical vapor deposition, phase 1

The development of a dichlorosilane-based reductive chemical vapor deposition process for the production of polycrystalline silicon is discussed. Experimental data indicate that the ease of ignition and explosion severity of dichlorosilane (DCS)/air mixtures is substantially attenuated if the DCS is diluted with hydrogen. Redesign of the process development unit to accommodate safety related information is described. Several different sources of trichlorosilane were used to generate a mixture of redistributed chlorosilanes via Dowex ion exchange resin. The unseparated mixtures were then fed to an experimental reactor in which silicon was deposited and the deposited silicon analyzed for electrically active impurities. At least one trichlorosilane source provided material of requisite purity. Silicon grown in the experimental reactor was converted to single crystal material and solar cells fabricated and tested

The African Telecommunications Union: A Pan-African Approach to Telecommunications Reform

This article examines the organisational structure and strategic plans of the African Telecommunica- tions Union (ATU). Although the ATU has been restructured to include private telecommunications entities as asso- ciate members, it remains essentially an inter-governmental agency. The article assesses the benefits of a regional approach to telecommunications reform and proposes that regional economic organisations replace the nation states as members of the ATU. Although the goals of the ATU, as articulated in its strategic plans are laudable, clearly de- fined benchmarks and specific strategies to achieve them are needed to make the organisation more effective

Private Sector Influence In The International Telecommunication Union

This paper aims to examine the influence of private corporations in the tripartite structure of the International Telecommunications Union (ITU): Telecommunications Standardization, Radiocommunication, and Telecommunications Development. The paper finds that, in the standardization sector, power has been effectively transferred from nation states to the private corporate sector since the approval process now enables standards to be approved by members of the study group that developed them, which is essentially the private sector. In the radiocommunication sector, the private sector continues to conduct much of the requisite technical work, but national governments are ultimately the decision makers and, further, it is difficult to distinguish between treaty and non-treaty work. In the development sector, the ITU seeks to create an enabling environment for private investment in developing countries and actively seeks to build private sector partnerships. In the long run the ITU may be unable to satisfy either its narrow corporate constituency or the vast majority of its developing country members. As the United Nations agency which coordinates satellite spacing and allocates access to the electromagnetic spectrum on an international basis, the ITU is the world\u27s most prominent international telecommunications institution, so its structural modifications and membership changes are of great significance in a world increasingly dependent on a global grid of wired and wireless telecommunications networks
