THE EFFECT OF FRICTION AND JOINTS RIGIDITY ON THE POWER CHARACTERISTICS OF ROTATING CHUCKS
- AUTHOR(S):
T. Al-Quraan, Y. Kuznetsov
- ABSTRACT:
Authors carry out the influence analysis of friction forces, joints contact rigidity and "clamping element-clamping object" and "clamping element-clamping chuck" subsystems’ rigidities proportion on the different clamping stages in the cases of non-rotating and rotating spindle, taking into account the centrifugal forces of unstable clamping elements. Recommendations on the improvement of clamping chucks power characteristics at high-speed treatment are given here.

- AUTHOR(S):
M. Slavov
- ABSTRACT:
This paper presents experimental results from study of typical scenarios for quality of service. The experiments show the imp act of the major parameters, which influence the quality of service - packets lost, round trip time, jitter and packets delay. The paper shows the required devices configurations as well as statistics for discarded packets.

RESEARCH OF THE INFLUENCE OF PARAMETERS ON THE TELETRAFFIC MODEL OF VOICE SERVICES

- ABSTRACT:
In Internet network data packets are transmitted to the series and breaks, and not permanently unlike some other types of networks. This is done to save network resources. Interactive services with data transmission usually requires duplex transmission, while access to databases requires simplex transmission. The traffic in these networks can be modeled as Poisson process interrupted or On-Off process. Interrupted Poisson flow is used to generate uneven traffic flow at imitative modeling and assessment Teletraffic models such calls are
generated by Poisson incoming flow at a constant intensity.

USING STANDING WAVES IN PIEZOELECTRIC ARRAY
- AUTHOR(S):
D. Kolev
- ABSTRACT:
Resonance piezoelectric arrays have high sensitivity but the data acquisition can be split in two basic approaches – detection of the frequency shift or detection of the amplitude change. Both methods have their own advantages and disadvantages but for more fast data acquisition, it is preferable to use the amplitude method. The current article reviews the problems connected with the amplitude method of data acquisition and suggests some solutions to them.
