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

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

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

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

Mini project report on
PLANER MILLING MACHINE ACCOMMODATED WITH DRILL HEAD

INTRODUCTION:
What is Planer-milling machine?

Planers and shapers are now obsolescent, because milling machines have eclipsed them as the machine tools of choice for doing work, as the rate of metal removal is quantitative.
planer-milling machines come in two kinds: double-housing and open-side. The double-housing variety has vertical supports on both sides of its long bed; the open-side variety has a vertical support on only one side ....etc
