Further irradiation, above 8 krads caused permanent damage associated with the attenuation of light emitted (high doses). As the same effect by gamma, in previous work, but in the increase in light intensity and current in low doses up to 1Mrads and damage occurs with 2Mrads. The I-V and C-V curves were sensitive to electron beam and gamma doses. This effect of LEDs can be successfully used for the determination of the absorbed dose in either low or high level. The range of low level was from 1 krad up to 8 krads and the high level is from 1 Mrad up to 20 Mrads or higher. Also /spl gamma/-rays doses behaved the same trend but the damage effect was more than electron beam at the same doses. The LEDs sample annealed after irradiation by electron beam and /spl gamma/-rays at room temperature for 1 year. The values of forward current reviewed to 12/spl plusmn/2% and 15/spl plusmn/2.5% from their original values. Oven annealing at different temperatures were ranging up to 250/spl deg/C. The output light intensity levels recover to around 17%, 23%, 39% and 54% of the initial values with annealing temperatures 100, 150, 200, and 250/spl deg/C respectively, in 1 H.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

Such high-frequency applications require that the modulator be clocked at a high frequency, which in turn, requires the modulators' loop filters to be built as continuous-time circuits (e.g. using LC resonators) rather than discrete-time circuits (e.g. switched capacitors). All the previous analysis of continuous-time bandpass /spl Sigma//spl Delta/ modulators considered the assumption of having filter with an infinite quality factor (Q). This assumption is impractical especially with on-chip filters which leads to an approximate noise transfer function (an infinitely deep notch in the quantization noise) and approximate signal to noise ratio (SNR). In this paper, a more accurate z-domain loop transfer function is derived. This loop transfer function is used in finding the noise transfer function. The effect of the resonator Q in the depth of the notch on the noise transfer function is analyzed. Derivation of a mathematical expression for SNR, using the exact formula of the loop transfer function, is provided. Also, the dependence of the modulator's SNR on the resonator Q is presented.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.

Speech recognition is a computationally demanding task, specially the pattern matching stage. The Hidden Markov Model (HMM) is considered the most powerful modeling and matching technique in the different speech recognition tasks. Implementing the pattern matching algorithm, which is time consuming, using dedicated hardware will speed up the recognition process. In this paper, a pattern matching algorithm based on HMM is implemented using Field Programmable Gate Array (FPGA). The forward algorithm, core of matching algorithm in HMM, is analyzed and modified to be more suitable for FPGA implementation. Implementation results showed that the recognition accuracy of the modified algorithm is very close to the classical algorithm with the gain of achieving higher speed and less occupied area in the FPGA. The proposed approach is used for isolated Arabic word recognition and achieved a recognition accuracy comparable with the powerful classical recognition system.","PeriodicalId":180690,"journal":{"name":"Proceedings of the 12th IEEE International Conference on Fuzzy Systems (Cat.
