The need for a computer-based central reservation system for smaller hotels, guesthouses and resortsPretorius, P. 28 August 2012 (has links)
M.Comm. / South Africa has become an accepted tourist destination since the 1994 general elections and the successful presentation of the 1995 Rugby World Cup event. The increase in the number of overseas visitors is reflected in higher arrival figures at our airports. Overseas tourists initially booked into the higher star rated hotels, but this trend quickly changed when they indicated a preference for the smaller hotels and the more personalised guesthouses. The recent establishment of hotels of well known world brands such as Hilton, Hyatt and others saw an increase in supply. These hotels were established with their links to the global reservation networks through which their reservations are accepted. The South African lodging industry now has to cope with management of the changes in demand in the face of world-wide computerised distribution. The guesthouses, smaller hotels and resorts tend to still utilise the printed media, mail or telephone bookings to communicate with prospective tourists. Although information technology is improving and becoming more accessible, only a few of the bigger South African hotel groups have utilised it to improve productivity and efficiency and to manage demand. A number of central reservation systems are in operation elsewhere in the world which allow the participants to present their establishments through the global travel agent networks such as Galileo and Worldspan. Trends in distribution of the lodging industry make it imperative to participate in such a system or face isolation from the world of tourism. The aim of this study is to establish the need for an integrated computer-based central reservation system for the smaller lodging establishments in South Africa. Depth interviews were conducted with a selected number of experts in the industry and the most important results of this empirical research were: The South African government has effectively withdrawn from the development of the tourism industry. The South African banks should be approached to establish such a system since they have proven expertise and knowledge of the operations of similar systems and would be in a position to make adequate funds available to allow the system to succeed. The system should be established with the capacity to link into world-wide distribution systems such as Galileo. The travel agents should be the first group to have access to this system since they are accepted as the driving force when implementing new solutions in the industry. Access through the Internet could follow. The cost of making a reservation at a lodging establishment is for the account of the hotel or guesthouse. The cost of accepting reservations from overseas tourists must be negotiated to be within the affordable range of the smaller lodging establishments. The establishment

An adaptive QoS framework for integrated cellular and WLAN networks.Min, Geyong, Mellor, John E., Al-Begain, Khalid, Wang, Xin Gang, Guan, Lin January 2005 (has links)
No / The design of a network architecture that can efficiently integrate WLAN and cellular networks is a challenging task, particularly when the objective is to make the interoperation between the two networks as seamless and as efficient as possible. To provide end-to-end quality of service (QoS) support is one of the key stages towards such a goal. Due to various constraints, such as the unbalanced capacity of the two systems, handoff from user mobility and unreliable transmission media, end-to-end QoS is difficult to guarantee. In this paper, we propose a generic reservation-based QoS model for the integrated cellular and WLAN networks. It uses an adaptation mechanism to address the above issues and to support end-to-end QoS. The validity of the proposed scheme is demonstrated via simulation experiments. The performance results reveal that this new scheme can considerably improve the system resource utilization and reduce the call blocking probability and handoff dropping probability of the integrated networks while maintaining acceptable QoS to the end users.

Non-industrial Landowners, the Incentive to Forego Harvesting, and the Importance of Scale of ActivitiesVokoun, Melinda Marie 13 May 2002 (has links)
Despite all that has been written regarding NIPF landowners, there have not been any studies providing a clear examination of willingness to harvest using a range of harvesting prices. An interesting problem that has not been previously examined is the determination of the relationship between the decision to harvest and the characteristics of owners and their land, such as preferences, landowner type (absentee vs. resident), site qualities, that function in determining potential scale of harvesting activities. This study examines which of these characteristics are important in landowner decisions regarding timber harvesting. Landowner access to land and preferences regarding land use are important in the decision to forego harvesting, while landowner type (absentee vs. resident), access to land, and preferences regarding land use are important in determining scale activities. / Master of Science

Pre-development hydrologic conditions of the Salt River Indian Reservation, East Salt River Valley, central Arizona, with an emphasis on the groundwater flow regimePorcello, John Joseph, 1963- January 1989 (has links)
A study of the Salt River Indian Reservation in central Arizona evaluated pre-development hydrologic conditions with an emphasis on simulating ground-water flow conditions within the reservation, where data was scarce before extensive aquifer pumping began in 1940 in adjoining portions of the East Salt River Valley. Water-resource development began in the valley with the completion of the Tempe Canal in 1871. Additional canals and irrigated agriculture spread quickly in areas along the Salt River, which has a mean annual flow of about 1.25 million acre-feet. Pre-development ground-water flow was horizontal and steady-state. The simulation indicated that the available water-level data, though corrupted in areas adjacent to the river, more properly described the virgin system than flow estimates. Sensitivity analyses indicated that simulated heads on the reservation were sensitive to all processes except evapotranspiration. Recharge through the riverbed, evapotranspiration, and subsurface outflow were all co-dependent.

Contribution aux techniques dites d'ajout de signal pour la Réduction du Facteur de Crête des signaux OFDM. / Contribution to reduction the Peak-To-Average Power Reduction in OFDM systems by thanks to the Adding Signal Based TechniquesDiallo, Mamadou Lamarana 08 June 2016 (has links)
Comme toutes modulations multiporteuses, l'OFDM souffre d'une forte variation d'amplitudes qui se traduit par un PAPR élevé. Cette caractéristique de l'OFDM la rend très sensible aux non-linéarités de l'amplificateur de puissance. Pour faire face à cette problématique, on peut surdimensionner l'amplificateur de puissance (solution non efficace en terme de rendement énergétique), linéariser l'amplificateur via les techniques de pré-distorsions, ou réduire le PAPR du signal avant amplification. L'objectif de cette thèse s'inscrit dans cette dernière thématique et plus particulièrement sur les techniques dites d'ajout de signal.Dans cette thèse, après une étude sur l'état de l'art des techniques de réduction du PAPR et en particulier les techniques dites d'ajout de signal, nous avons développé et proposé de nouvelles techniques de réduction du PAPR. Ces contributions s'articulent principalement autour des techniques de Clipping et de la Tone Reservation. / One of the main drawbacks of the OFDM modulation scheme is its high Peak-To-Average Power variation (PAPR) which can induce poor power efficiency at the transmitter amplifier. The digital base band pre-distortion for linearisation of power amplifier and the PAPR mitigation are the most commonly used solution in order to deals with efficiency and linearisation at the high power amplifier. This thesis is focused on the PAPR mitigation solution, and particularly on the adding signal based techniques. The proposed solutions in this report are about improving the Tone Reservation method which is the most popular adding signal based technique for PAPR mitigation, and also the classical clipping method which is the most simple method (in terms of computational complexity) actually.
