08 Sep 1995TL;DR: In this article, the authors present a mobile communication system in which various access methods may be selected according to the user's priority, and each of a mobile station and radio base stations has a radio processor, which has TDMA, CDMA and FDMA communication units.
Abstract: A mobile communication system in which various access methods may be selected according to the user's priority. In the mobile communication system, each of a mobile station and radio base stations has a radio processor, which has TDMA, CDMA and FDMA communication units. The CDMA communication unit comprises channel coders each for performing a primary modulation to a transmitting signal, spread-spectrum code generators for respectively generating different spread-spectrum signals, a clock generator/controller for controlling the generation of chip clocks to control the generation of the spread-spectrum codes, oscillators for setting different carrier frequencies to outputs calculated as products, and a CPU for generally controlling various parts or elements to control the assignment of a CDMA signal or a TDMA signal to an arbitrary time slot transmitted from the TDMA communication unit. The radio processor transmits different signals of different access methods existing in each time slot of the same frame different signals.

TL;DR: The growth inhibition of these algae caused by chlorophenols is mostly influenced by lipophilicity, as is stated frequently in toxicity studies using aquatic animals.
Abstract: The growth inhibition (96-h EC50) of two species of green algae, Selenastrum capricornutum and Chlorella vulgaris, caused by phenol and 12 chlorophenols (from mono-Cl to penta-Cl) was determined according to the Organization for Economic Cooperation and Development guidelines for testing chemicals. The responses of the algae to the chemicals were measured by cell counting, and 96-h EC50 values were correlated with six physicochemical parameters of chlorophenols. The parameters employed in the quantitative structure-activity relationship (QSAR) analyses were n-octanol/water partition coefficient (log Pow), dissociation constant (pKa), Hammett Σσ constant, index of valence molecular connectivity (1χv), perimeter of the efficient cross section of molecule (ΣD) and melting point (F). In the S. capricornutum assay, the toxicity increased as the number of substituted chlorine atoms increased. In the C. vulgaris assay, although toxicity increased from phenol to dichlorophenol, the toxicities of di-, tri-, tetra- and pentachlorophenol were almost the same. QSAR study shows that log Pow gives the best correlation, even in the C. vulgaris assay, by the use of the square of log Pow. Therefore, the growth inhibition of these algae caused by chlorophenols is mostly influenced by lipophilicity, as is stated frequently in toxicity studies using aquatic animals.

05 Jul 1991TL;DR: In this paper, a two-dimensional positioning operation using GPS signals from satellites is carried out, which comprises reading the previous altitude data from the altitude storage section, calculating the atmospheric pressure deviation from the AP sensor output as caused by the movement of the body; calculating the altitude deviation from AP sensor outputs, and then calculating the current altitude from altitude deviation and the previous data; and finally calculating the 2D position data from GPS signals and current altitude data.
Abstract: The navigation system using GPS signals from satellites first checks whether or not there are four or more satellites in radio range of the moving body. If so, the position calculation section performs an ordinary three-dimensional positioning operation to provide an accurate fix of the moving body. When the number of satellites within the radio range is three or less, the two-dimensional positioning operation is carried out, which comprises reading the previous altitude data from the altitude storage section; calculating the atmospheric pressure deviation from the atmospheric pressure sensor output as caused by the movement of the body; calculating the altitude deviation from the previous altitude data and the atmospheric pressure deviation; calculating the current altitude from the altitude deviation and the previous altitude data; and then calculating the two-dimensional position data from the GPS signals and the current altitude data. This method produces no errors which would otherwise be caused by changes in the altitude of the moving body but provides accurate two-dimensional fix data of the body.
