    Opis:
    In this paper a new continuous model for vibration analysis of a beam with an open edge crack is presented. A quasi-linear displacement filed is suggested for the beam and the strain and stress fields are calculated. The equation of motion of the beam is calculated using the Hamilton principle. The calculated equation of motion is solved with a modified weighted residual method and the natural frequencies and mode shapes are obtained. The results are compared with those obtained by finite element method and an excellent agreement has been observed. The presented model is a simple and accurate method for analysis of the cracked beam behavior near or far from the crack tip.

    Opis:
    Despite the importance of calcium in many fruit species and the effects of calcium application, there is little or no reliable information on the effect of CaCl2 spray at different fruit development stages on the fruit mineral nutrient content during the growing season and at harvest. Therefore, this study has been conducted to evaluate the effect of calcium chloride (CaCl2, 15 g L-1) spray at different fruit development stages on the accumulation Ca and other macronutrients in cv. Hayward kiwifruit grown at two locations. In order to find the absorbality of Ca at different spraying times, fruits were harvested 7 days after a Ca treatment. Additionally, the mineral composition of kwifruit was determined at the stage of harvest ripeness. The results showed that the absorbality of Ca by kiwifruit from Ca spray decreased significantly with the progressing fruit development. The highest fruit Ca content was found when the fruit plants were sprayed at 35+80 DAFB and 35+80+120 DAFB, irrespectively of the location of an orchard. At a later Ca spraying application, the N content in kiwifruit significantly decreased, but the K and Mg content slightly increased. In contrast, the K/Ca, N/Ca, Mg/Ca and (K+Mg)/Ca ratios of CaCl2 sprayed fruits was lower than in the control and the ratio values were more balanced in the Ca treated fruit than in the control. Overall, three CaCl2 (15 g L-1) sprays could effectively improve the fruit quality by balancing the Ca ratio to other macronutrients. Therefore, Ca spray treatments could be a recommended treatment in growing cv. Hayward kiwifruit.

    Opis:
    This paper presents a novel fully differential high-speed and high-resolution Digital to Analog Converter (DAC) based on new reliable hybrid R-C technique. In the proposed idea the four LSB bits and eight MSB bits are implemented as a resistor string and new merged capacitor technique respectively. Applying the suggested method the SNDR and Effective Number of Bits (ENOB) of the proposed DAC achieve 70.22dB and 11.41 bit at the 1.25GS/s sampling rate correspondingly. In the proposed method the total capacitors of the 8 MSB bits are reduced up to 78% compared to the conventional one noticeably. As a result, the power consumption and speed of the suggested DAC are decreased and increased respectively. Moreover, the total power consumption of the proposed DAC is 2.27mW with the power supply of 1.8 volts as well. Meanwhile, for the correctness of the proposed 12bit DAC, 200 iterations in transient Monte-Carlo analysis (parasitic capacitance included ([symbol] mismatch = 1.2%)), and the SNDR simulation results versus different input frequency at fS=1.25GS/s sampling rate are applied too. The maximum Integral Nonlinearity (INL) and the maximum Differential Nonlinearity (DNL) are -0.47/+0.35LSB and -0.42/+0.29 LSB respectively. The proposed DAC structure is simulated in all process corners and performed using the HSPICE BSIM3 model of a 0.18μm CMOS technology.

    Opis:
    In this paper, fabrication of open-celled porous Fe-10%A1 foam by space-holder technique in which NaCl powder and polyester resin were utilized as space holder and binder respectively to generate 30-80% porosities was studied. FeAl solid solution was prepared via mechanical alloying method after 25 h high energy milling process. The results indicate that the size and shapes of the pores are determined by the size and shapes of NaCl particles. Also, when compaction pressure was in the range of 70-150 MPa and the sintering process was performed at temperature around 1100°C, the samples had the best quality. Microstructure observations show the pore size was in the range of 200-500 μm.
    W niniejszej pracy badano wytwarzanie techniką wypełniacza przestrzeni piany Fe-10%Al o otwartej porowatości, w której proszek NaCl i Żywicę poliestrową wykorzystano odpowiednio w roli wypełniacza porów i spoiwa do wytworzenia piany o 30-80% porowatości. Roztwór stały FeAl został wytworzony poprzez mechaniczne stopowanie przez 25 h w trakcie wysokoenergetycznego mielenia. Wyniki wskazują, że rozmiar i kształt porów determinowany jest przez wielkość i kształt cząstek NaCl. Ponadto, gdy ciśnienie prasowania było w zakresie 70-150 MPa a proces spiekania prowadzono w temperaturze około 1100°C. próbki miały najwyższą jakość. Obserwacje mikrostruktury wykazały, że rozmiar porów mieścił się w zakresie 200-500 μm.
