抄録: In this paper, we propose an error detecting hardware-scheme for the combinatorial logic circuits (the scheme is named by us as the Coincidence Detecting Scheme). Compared with the software-type testing, the hardware-type detecting has sveral merits such as (1) simultaneous detection of the errors when they occur, doing usual operations, (2) the possibility of detecting the intermittent faults, etc. But, it is very important to make the detecting circuit to be small one, for the reliability and the frugality of the detecting circuit. Hence, AND-Inverse, Output-Side AND Detecting Schemes are proposed as the special cases of the Coincidence Detecting Scheme. And, as a result, it is shown that (1) AND-Inverse Detecting Scheme has minimal redundancy (2 AND and 1 EXOR elements are sufficient excepting NOT), (2) Output-Side AND Detecting Scheme can be applicable to any given combinatorial logic circuit which is detected, and (3) the (average) detecting rate is largely improved by using parallel extensions of such schemes. Of course, above results hold under the situation that any stuck-at faults (at input and/or output points) can be detected.1991-03-30T15:00:00Z大型小売店における売上予測(第2報)橋本, 郁郎http://hdl.handle.net/11133/8732013-01-10T16:37:49Z1991-03-30T15:00:00Zタイトル: 大型小売店における売上予測(第2報)

抄録: A sales forecasting is very important for making a management plan and proceeding to research development and product planing. There are various forecasts such as technical forecast, economic forecast, sales forecast and product forecast. Succeeding to the previous report, the present study discusess further sales forecast of clothing in the department stores in Aichi Prefecture by means of a multiple regression analysis. In the previous report, such dependent valiables were used as consumer expense, sales floor area, time and consumer price index. The present study added a dummy variable to the dependent variables for the improvement of autocorrelation of residual. As the result of the analysis, the autocorrelation of the residual are improved very much in which the forecast error rates are 7.13% max. and 0.36% min.1991-03-30T15:00:00Z等曲げを受けるRC梁の曲げ塑性変形挙動の寸法効果小池, 狹千朗http://hdl.handle.net/11133/8742017-12-06T05:58:18Z1991-03-30T15:00:00Zタイトル: 等曲げを受けるRC梁の曲げ塑性変形挙動の寸法効果

抄録: In this study, the variations of moment-curvature relationships of reinforced concrete beams of various sizes under uniform flexural moment were examined. The size effect on the compressive strength and the complete stress-strain behavior of confined concrete were also examined by using a stiff compressive testing machine. The following results were obtained : 1) Strain at the maximum stress of confined concrete increases with decreasing size of specimen for the large percentage of transverse reinforcement. 2) Moment-curvature relationships of reinforeced concrete beams are affected by the size of beam, i.e., the moment-curvature relationships of large size beam specimens are rather brittle compared with those of small specimens.1991-03-30T15:00:00ZShort Time DFTフィードフォワードシラビックコンパンダの特性と構成岸, 政七http://hdl.handle.net/11133/8752013-11-11T05:12:36Z1991-03-30T15:00:00Zタイトル: Short Time DFTフィードフォワードシラビックコンパンダの特性と構成

抄録: Reducing the spectrum occupancy over radio channels is as well known as important to prevent from exhausting radio spectrum resources. The syllabic compandor provides with indispensable function both to improve speech quality and reduce fading noise over radio channels against to saving transmission power and narrowing spectrum occupancy. Therefore, many invesitigations are keenly studied on realizing the syllabic compandors. Unfortunatelly, most of them have been concerned with approximation in the way of AM demodulation to estimate envelope component with certain intermodulation error between input signals and their envelopes. When such approximating envelope detector is adopted to compressor/expander, the intermodulation error in the approximately estimated envelopes induces harmonic distortions to expand spectrum occupancy and to degrade speech quality in the aprior communication systems. An exact compandor is succesfully discussed with employing instantaneous spectrum analysis insted of AM demodulation approximations in realizing the envelope detectors, which is based on that compressing/expanding is precisely performed on the frequency domain. After being decomposed into instantaneous spectrum, input signals are processed via dividing/multiplying along each vector of the instantaneous spectrum components. The output signals are synthesized from the compressed/expanded instantaneous spectrum without alomost any harmonic distortions.1991-03-30T15:00:00Z
