When measuring the SAR due to a mobile phone the phone is placed against a representation of a human head (a "SAR Phantom") in a talk position. The SAR value is then measured at the location that has the highest absorption rate in the entire head, which in the case of a mobile phone is often as close to the phone's antenna as possible.
If a negative value is found for AFN, that means that the action would generate extra income that could be invested elsewhere. The AFN equation is as follows: AFN = (A*/S 0)ΔS – (L*/S 0)ΔS – MS 1 (RR) [1] Where: A* = Assets tied directly to sales and will increase L* = Spontaneous liabilities that will be affected by sales.
where SAR n and SAR n+1 represent the current period and the next period's SAR values, respectively. EP (the extreme point) is a record kept during each trend that represents the highest value reached by the price during the current uptrend – or lowest value during a downtrend. During each period, if a new maximum (or minimum) is observed ...
SR-50 (1974) Printed circuit board. Data code 035: 3rd week 1975. The SR-50 was Texas Instruments' first scientific pocket calculator with trigonometric and logarithm functions. . It enhanced their earlier SR-10 and SR-11 calculators, introduced in 1973, which had featured scientific notation, squares, square root, and reciprocals, but had no trig or log functions, and lacked other featur
The TI-85 is a graphing calculator made by Texas Instruments based on the Zilog Z80 microprocessor.Designed in 1992 as TI's second graphing calculator (the first was the TI-81), it was replaced by the TI-86, which has also been discontinued.
The Little Professor was first released by Texas Instruments on June 13, 1976. [5] As the first electronic educational toy, [6] [7] the Little Professor is a common item on calculator collectors' lists. [8] In 1976, the Little Professor cost less than $20. More than 1 million units sold in 1977. [9]
The TI-59 is an early programmable calculator, that was manufactured by Texas Instruments from 1977. It is the successor to the TI SR-52, quadrupling the number of "program steps" of storage, and adding "ROM Program Modules" (an insertable ROM chip, capable of holding 5000 program steps).
The TI-57 was a programmable calculator made by Texas Instruments between 1977 and 1982. There were three machines by this name made by TI, the first was the TI-57 with LED display released in September 1977 along the more powerful TI-58 and TI-59 .
