The measurement of tractor transmission losses

Journal of Agricultural Engineering Research, 1974
Abstract The method of measurement and results are presented for the losses in the transmission of an agricultural tractor. The results describe the effect of oil temperature and gear setting on the level of loss.

Crosstalk Loss Requirements for PCM Transmission

IEEE Transactions on Communications, 1976
We present in this paper a unified approach to the crosstalk interference problem arising in PCM transmission on paired cables. For bipolar signaling, and three types of commonly used channel shaping, viz., cosine, raised cosine, and Gaussian, we present the minimum average near-end crosstalk (NEXT) and far-end crosstalk (FEXT) loss requirements at any

Fractional Transmission Line with Losses

Zeitschrift für Naturforschung A, 2014
Abstract In this manuscript, the fractional transmission line with losses is presented. The order of the Caputo derivative is considered as 0 < β ≤ 1 and 0 < γ ≤ 1 for the fractional equation in space and time domain, respectively. Two cases are solved, with fractional spatial and fractional temporal derivatives, and also numerical

Sound Transmission Loss

2019
The transmission of sound through walls and barriers is an extremely important topic for noise control engineers. In this chapter we examine the basic principles of how sound passes through walls. The primary physical characteristics that influence sound transmission through walls are studied, including the importance of mass and how the bending ...

Loss in an Infinite Transmission Line

Journal of the Physical Society of Japan, 2005
An infinitely long transmission line appears to have an ohmic conductance even when loss in circuit elements approaches zero. We show that the real part of the admittance of the transmission line derives from a dense distribution of resonance absorption lines.

The transmission loss of double panels

Journal of Sound and Vibration, 1967
Abstract Existing theories relating to the transmission loss of double panels are studied. It is shown that it is not possible to obtain agreement between theoretical and measured curves for random incidence transmission loss without the use of terms other than the mass of the panels arid their separation.

Transmission Loss of Partition Walls

IETE Journal of Research, 1965
ABSTRACTResults of the measurement on sound insulation of a few partition walls are presented. The sound insulation has been measured in the transmission-reverberation chamber of this Institute. The results are compared with theoretical predictions. A simplified method is adopted to obtain approximate theoretical values of the transmission loss (T.L ...

Unconscious Communication and the Transmission of Loss

Journal of Infant, Child, and Adolescent Psychotherapy, 2004
In this paper, I examine the sense of loss that some adoptive parents experience in being unable to conceive and how this interfaces with the “ambiguous loss” of the birth mother for the adoptee. I outline an interpersonal-relational perspective on adoption using current thinking on the concept of projective identification.

Sound Transmission Loss of Panels

2015
In general, the noise level inside a building or structure is determined by the transmission of air-borne sound from external and internal acoustic sources and by structure-borne sound induced by some mechanical sources.
