Efficient storage and transmission of ladar imagery
Applied Optics, 2003We develop novel methods for compressing volumetric imagery that has been generated by single-platform (mobile) range sensors. We exploit the correlation structure inherent in multiple views in order to improve compression efficiency. We show that, for lossless compression, three-dimensional volumes compress more efficiently than two-dimensional (2D ...

Energy-efficient transmission with data sharing
2015 IEEE Conference on Computer Communications (INFOCOM), 2015In a wireless system, when multiple applications can share data transmitted by rate-adaptive wireless devices, there exists a trade-off between transmission redundancy and energy efficiency. This paper conducts the first theoretical analysis on such a trade-off.

Efficient fax transmission of halftone images
Journal of Electronic Imaging, 1992The efficient encoding and transmission of information for facsimile communication relies on redundancy in the scanned pixels. Halftone images, especiaily those rendered by high-quality dispersed dot techniques, are "busy" with alternative black and white pixels and shorter run lengths as compared to text information.

Ordered Transmission for Efficient Wireless Autonomy
2018 52nd Asilomar Conference on Signals, Systems, and Computers, 2018Collaborative autonomous systems may rely on wireless communications in dynamic settings. Fundamental to these systems is collaborative decision making, gathering evidence and efficiently producing a joint decision. In many applications fast decision cycles are required and the speed of decision limits the overall system performance.

Transmission efficiency in photon counting channels
IEEE Transactions on Communications, 1989An investigation is presented of the maximum transmission efficiency that can be reached over an ideal photon counting channel, having fixed the bandwidth expansion factor. First, the ideal situation, represented by C.E. Shannon's (1959) theorem for discrete channels, is analyzed.

Energy efficient coding and transmission
IEEE VTS 53rd Vehicular Technology Conference, Spring 2001. Proceedings (Cat. No.01CH37202), 2002Efficient transmission of multimedia signals from energy limited portable devices requires a fresh look at the tradeoffs between source compression, channel coding and transmission strategies. We provide optimum operating points in terms of end-to-end source distortion and total energy consumption of the mobile due to compression, channel coding and ...

High Efficiency Transducer for Transmission to Air
The Journal of the Acoustical Society of America, 1959The basic problems of transduction to low acoustic impedance media are considered. The advantages offered by flexure mode vibration of driving elements are shown. Selection of a driving element consisting of a free disk supported at the nodal circle is made. Fabrication in quartz and ceramic is described.

Energy Efficient Radio Transmission with Wavelets
2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018The application of wavelet packet modulation in the green radio transmission is addressed. Using the wavelet technology, and complying with the wavelet restrictions, an optimal signal will be designed by the minimization of the transmit power.
