THE IMPACTS OF ANTENNA AZIMUTH AND TILT INSTALLATION ACCURACY
ON
UMTS NETWORK PERFORMANCE


Abstract

Inconsistencies in setting up antenna azimuth and tilt during installation may reduce overall network performance. However, the degree of quality degradation depends on the amount of the discrepancy between the designed and installed parameters. The paper invest ....etc

Abstract
• Measurement and estimation of packet loss characteristics are challenging due to the relatively rare occurrence and typically short duration of packet loss episodes.
• The objective of our study is to understand how to measure packet loss episodes accurately with end-to-end probes.
• We evaluate the capabilities of our methodology experimentally by developing and implementing a prototype tool, called BADABING.

Abstract: In this paper, we propose an accurate method to evaluate the available bandwidth in IEEE 802.11-based ad hoc networks. We improve the method described in. We evaluate our solution on di_erent scenarios. We also provide a comparison with different QoS routing protocols, BRuIT, AAC and QoS-AODV, based on di_erent available bandwidth estimation techniques.

Abstract

The accuracy of the precise machines (e.g. Coordinate measuring machines) is of micrometer range and even less. The play of the bearings, the change of the position of moving parts, wear, environment influence, etc. reduce the final accuracy. The existing methods to increase the accuracy of precise equipment are complicated and of high cost. The authors present a new concept in the design of error compensating systems - active frames and structures for precision technological equipment and measuring machines. It is proposed to inser ....etc

Global Issues: Ozone Depletion, Global Warming and Acid Rain

Introduction

Air pollution is exerting increasing impact on the environment. Humans have been altering the chemistry of the atmosphere on a global scale. These changes may:
Modify the global climate
Threaten the health of human beings
Create many environmental problems such as
Acid rain
Depletion of ozone layer
Global warming
Seriously upset the global ecosystem

What is ozone depletion?

Ozone is a highly reactive gas comprising ....etc

Modern radiation therapy techniques, such as stereotactic radiotherapy and tomotherapy, deliver the total treatment dose to the patient using many small fields. This helps to construct a dose distribution which delivers a high dose to the tumour, while minimizing the dose to normal tissue. When considering a single small field, the dose resulting from that small field is usually reported as a relative dose factor (RDF). The RDF is the percentage of dose in a small field as compared to a large reference field. Task group report #51 from the Amer ....etc
