This little volume was not_ meant to be a cram book, nor in any way a substitute for a textbook on the subject, but was written as a practical guide to nurses, dressers, house surgeons, and general practitioners. It fulfils! its function; admirably. Probably the most useful part of this very useful little book is the three tables which will be found in an envelope at the end of the book; they a...

The control system of laser leveling machine was redesigned and tested to improve the performance and decrease the cost. In this paper, the control system of the machine which contains transmitter, receiver and controller was introduced. The receiver had silicon photoelements as photoelectric sensors. A kind of light filter was designed which was composed of red color optical glass and interfer...

In this paper, we quantitatively (mathematically) reason the energy savings achieved by the Leveling and Sectoring protocol. Due to the energy constraints on the sensor nodes (in terms of supply of energy) energy awareness has become crucial in networking protocol stack. The understanding of routing protocols along with energy awareness in a network would help in energy optimization with effici...

in many countries, leveling networks are established for height determination which is one of the most important topics in geodesy. in these networks, the sum of the leveled height differences between a and b will not be equal to the difference in the orthometric heights ha and hb. the reason is that the leveling increment ?n, as we henceforth denote it, is different from the corresponding incr...

There are three popular methods to understand the land subsidence: leveling, Global Navigation Satellite System, and Interferometric Synthetic Aperture Radar (InSAR) analysis using SAR images. While both leveling System can measure amount of subsidence only at specific points, InSAR observe a wide area in short time intervals. In terms accuracy, however, is inferior leveling; centimeter/millime...

Phase change memory (PCM) is the best candidate device among next generation random access memory technologies. PCM has a potential to replace Flash memory due to non-volatility and in-place programmability, and low power consumption. Even though lifetime of PCM is longer than flash memory, wear leveling is needed because of non-uniformity of storage workload or malicious attack. In this paper,...
