Opis:
Visible light communication (VLC) is a promising technology for wireless communication networks. Optical code division multiple access (OCDMA) is a strong candidate for VLC-based applications. The predominant source of bit error in OCDMA is the multiple access interference (MAI). To eliminate MAI in synchronous OCDMA, zero cross correlation (ZCC) codes have been proposed. However, synchronization problems and multipath propagation introduce relative non-zero time delays. Therefore, the zero correlation zone (ZCZ) concept was introduced. In this paper, we propose a new method for generating ZCC codes. The proposed construction can accommodate any number of users with flexible Hamming weight. The numerical results obtained show that the proposed codes significantly reduce MAI, compared to ZCC, as well as ZCZ codes.

Opis:
In order to meet the demand of high data rate transmission with good quality maintained, the multi-carrier code division multiple access (MC-CDMA) technology is considered for the next generation wireless communication systems. However, their high crest factor (CF) is one of the major drawbacks of multi-carrier transmission systems. Thus, CF reduction is one of the most important research areas in MC-CDMA systems. In addition, asynchronous MC-CDMA suffers from the effect of multiple access interference (MAI), caused by all users active in the system. Degradation of the system’s bit error rate (BER) caused by MAI must be taken into consideration as well. The aim of this paper is to provide a comparative study on the enhancement of performance of an MC-CDMA system. The spreading sequences used in CDMA play an important role in CF and interference reduction. Hence, spreading sequences should be selected to simultaneously ensure low CF and low BER values. Therefore, the effect that correlation properties of sequences exert on CF values is investigated in this study. Furthermore, a numerical BER evaluation, as a function of the signal-to-noise ratio (SNR) and the number of users, is provided. The results obtained indicate that a trade-off between the two criteria is necessary to ensure good performance. It was concluded that zero correlation zone (ZCZ) sequences are the most suitable spreading sequences as far as the satisfaction of the above criteria is concerned.

Opis:
In this paper, the removal of benzotriazole (BTA) was investigated by a Photo-Fenton process using nano zero valent iron (NZVI) and optimization by response surface methodology based on Box-Behnken method. Effect of operating parameters affecting removal efficiency such as H2O2, NZVI, and BTA concentrations as well as pH was studied. All the experiments were performed in the presence of ultraviolet radiation. Predicted levels and BTA removal were found to be in good agreement with the experimental levels (R2 = 0. 9500). The optimal parameters were determined at 60 min reaction time, 15 mg L-1 BTA, 0.10 g L-1 NZVI, and 1.5 mmol L-1 H2O2  for Photo-Fenton-like reaction. NZVI was characterized using X-ray diffraction (XRD), transmission electron microscope (TEM) images, and scanning electron microscope (SEM) analysis.

Opis:
The increased power density, reduced switching losses with minimum electromagnetic interference (EMI), and high efficiency are essential requirements of power converters. To achieve these characteristics, soft power converters employing soft switching techniques are indispensable. In this paper, a ZCS/ZVS PWM AC/DC converter topology has been emphasized, which finds applications in high power systems such as automobile battery charging and renewable energy systems. This converter scheme maintains zero current and zero voltage switching conditions at turn on and turn off moments of semiconductor switches, respectively and soft operation of rectifier diodes that lead to negligible switching and diode reverse recovery losses. Moreover, it improves power quality and presents high input power factor, low total harmonic distortion of the input current (THDI ) and improved efficiency. The validity of theoretical analysis of the proposed converter has been carried out experimentally on a 10 kW laboratory prototype. Experimental results prove that the soft switching operation of the semiconductor switches and diodes is maintained at 98.6% rated load efficiency. In addition, the performance evaluation has been performed by comparative analysis of the proposed converter with some prior art high power AC/DC converters. Efficiencies of the proposed and prior art high power topologies have been determined for different load conditions. The highest efficiency, power factor and lower THDI of the proposed converter topology complies with international standards.

Opis:
Zero-temperature limits of the local and global thermodynamic quantities in the nine-membered antiferromagnetic s=3/2 spin ring are investigated by means of numerical exact diagonalization. An anisotropic Heisenberg model with tunable bond defect reflecting continuously varying topology (from closed to open ring) is exploited. The frustrated and non-frustrated phases are identified in the ground-state phase diagram determined by a bond-defect strength and magnetic field. Near the phase boundaries significance of the thermal fluctuations affecting the estimates of the local magnetic quantities found earlier at T=1 K is revealed. For the global quantities the effects of thermal fluctuations are found much weaker. A sequence of the local magnetic moments is analysed and their experimental verification at the edges of the non-frustrated and within the entire frustrated phase is suggested at sufficiently low temperature.

Opis:
A correlation measuring tool for an endogenous pulsed neutron source experiment is developed in this work. Paroxysmal pulses generated by a bursts of neutron chains are detected by a 10-kbit embedded shift register with a time resolution of 100 ns. The system is implemented on a single reprogrammable device making it a compact, cost-effective instrument, easily adaptable for any case study. The system was verified experimentally in the Esfahan heavy-water zero power reactor (EHWZPR). The results obtained by the measuring tool are validated by the Feynman-α experiment, and a good agreement is seen within the boundaries of statistical uncertainties. The theory of the methods is briefly initiated in the text. Also, the system structure is described, the experimental results and their uncertainties are discussed, and neutron statistics in EHWZPR is examined experimentally.

Opis:
An embedded time interval data acquisition system (DAS) is developed for zero power reactor (ZPR) noise experiments. The system is capable of measuring the correlation or probability distribution of a random process. The design is totally implemented on a single Field Programmable Gate Array (FPGA). The architecture is tested on different FPGA platforms with different speed grades and hardware resources. Generic experimental values for time resolution and inter-event dead time of the system are 2.22 ns and 6.67 ns respectively. The DAS can record around 48-bit x 790 kS/s utilizing its built-in fast memory. The system can measure very long time intervals due to its 48-bit timing structure design. As the architecture can work on a typical FPGA, this is a low cost experimental tool and needs little time to be established. In addition, revisions are easily possible through its reprogramming capability. The performance of the system is checked and verified experimentally.

Opis:
The article presents a zero-dimensional mathematical model of a tubular fuel cell and its verification on four experiments. Despite the fact that fuel cells are still rarely used in commercial applications, their use has become increasingly more common. Computational Flow Mechanics codes allow to predict basic parameters of a cell such as current, voltage, combustion composition, exhaust temperature, etc. Precise models are particularly important for a complex energy system, where fuel cells cooperate with gas, gas-steam cycles or ORCs and their thermodynamic parameters affect those systems. The proposed model employs extended Nernst equation to determine the fuel cell voltage and steadystate shifting reaction equilibrium to calculate the exhaust composition. Additionally, the reaction of methane reforming and the electrochemical reaction of hydrogen and oxygen have been implemented into the model. The numerical simulation results were compared with available experiment results and the differences, with the exception of the Tomlin experiment, are below 5%. It has been proven that the increase in current density lowers the electrical efficiency of SOFCs, hence fuel cells typically work at low current density, with a corresponding efficiency of 45–50% and with a low emission level (zero emissions in case of hydrogen combustion).

Badano skuteczność rozkładu dwóch barwników azowych (Acid Red 27 – AR27 oraz Reactive Black 5 – RB5) w roztworach wodnych o stężeniu 100 mg/dm3 poddanych działaniu odczynnika Fentona modyfikowanego nanożelazem (H2O2/nFeo). W przypadku każdego barwnika określono najkorzystniejsze wartości parametrów procesu, przy których uzyskano widoczne odbarwienie roztworu (barwnik AR27: pH=3, dawka H2O2 40 mg/dm3, dawka nFeo 60 mg/dm3, czas reakcji 15 min, barwnik RB5: pH=3, dawka H2O2 50 mg/dm3, dawka nFeo 20 mg/dm3, czas reakcji 15 min). W tych warunkach zmniejszenie wartości ChZT roztworów barwników AR27 i RB5 wynosiło odpowiednio 82,6% i 86,5, a zmniejszenie ich toksyczności (mierzonej testem Microtox) – odpowiednio 100% i 92,7%. W celach porównawczych do rozkładu barwników zastosowano także klasyczny odczynnik Fentona (H2O2/Fe2+). Widoczne odbarwienie wodnego roztworu barwnika AR27 uzyskano w tym przypadku przy pH=3,5, dawce H2O2 60 mg/dm3, stosunku [Fe2+]/[H2O2]=0,3 w czasie 15 min, a barwnika RB5 pH=3,5, dawce H2O2 40 mg/dm3, stosunku [Fe2+]/[H2O2]=0,75 w czasie 15 min. Zmniejszenie wartości ChZT roztworów AR27 i RB5 wynosiło odpowiednio 71,5% i 71,8%, a zmniejszenie ich toksyczności – 100% i 84,4%. Obie zastosowane metody utleniania, poza odbarwieniem roztworów wodnych, pozwoliły na zmniejszenie wartości ChZT roztworów barwników do 21÷49 mgO2/dm3. Zgodnie z klasyfikacją toksyczności próbek wodnych, wszystkie badane roztwory barwników z klasy próbek wysokotoksycznych (toksyczność >75%), po poddaniu ich działaniu odczynnika Fentona można uznać za nietoksyczne (toksyczność <25%).
Effectiveness of two azo dyes decomposition (Acid Red 27 – AR27 and Reactive Black 5 – RB5) with the Fenton reagent modified with nanoiron (H2O2/nFeo) was studied in aqueous solutions at a concentration of 100 mg/L. For each dye, the most favorable process parameters were determined to obtain visual discoloration of tested solutions (AR27: pH = 3, H2O2 = 40 mg/L, nFeo = 60 mg/L, t = 15 min; RB5: pH = 3, H2O2 = 50 mg/L, nFeo = 20 mg/L, t = 15 min). Under these conditions, the decrease in COD values for AR27 and RB5 was 82.6% and 86.5, respectively and in toxicity (Microtox test) – 100% and 92.7%, respectively. For comparative purposes, classic Fenton reagent (H2O2/Fe2+) was also used for the dye decomposition. For AR27, the visual discoloration of the aqueous solution was obtained within 15 min at pH = 3.5, H2O2 = 60 mg/L, [Fe2+]/[H2O2]=0.3 and for RB5 – within 15 min at pH = 3.5, H2O2 = 40 mg/L, [Fe2+]/[H2O2]=0.75. The decrease in COD values for AR27 and RB5 was 71.5% and 71.8%, respectively and in toxicity – 100% and 84.4%, respectively. Both oxidation methods applied, beside visual discoloration of the aqueous solutions, allowed for the COD reduction to the level of 21–49 mgO2/L. According to the toxicity classification for water samples, all the highly toxic samples of dye solutions tested (toxicity >75%) could be considered non-toxic (toxicity <25%) after the Fenton reagent application.

Opis:
A product is referred to as robust when its performance is consistent. In current product robustness paradigms, robustness is the responsibility of engineering design. Drawings and 3D models should be released to manufacturing after applying all the possible robust design principles. But there are no methods referred for manufacturing to carry and improve product robustness after the design freeze. This paper proposes a process of inducing product robustness at all stages of product development from design release to the start of mass production. A manufacturing strategy of absorbing all obvious variations and an approach of turning variations to cancel one another are defined. Verified the application feasibility and established the robustness quantification method at each stage. The theoretical and actual sensitivity of different parameters is identified as indicators. Theoretical and actual performance variation and accuracy of estimation are established as robustness metric. Manufacturing plan alignment to design, complimenting the design and process sensitivities, countering process mean shifts with tool deviations, higher adjustable assembly tools are enablers to achieve product robustness.

Opis:
The use of Carrier Suppressed Non-Return to Zero (CSNRZ) and Carrier Suppressed Return to Zero (CSRZ) modulation formats in Dense Wavelength Division Multiplexing (DWDM) channels at 1 Gb/s and 10 Gb/s is investigated. The results of simulated analysis using Differential Quadrature Phase Shift Keying (DQPSK) and Offset Quadrature Phase Shift Keying (OQPSK) formats are presented. We demonstrate that Stimulated Brillouin Scatteriring (SBS) is a major contribution of the back-scattering signal. At bit rate of 1 Gb/s and 10 Gb/s, CSRZ-OQPSK modulation format has a low threshold for SBS signal generation. For a data rate of 1 Gb/s, high SBS threshold of 19.76 dBm for CSRZ-DQPSK is recorded. The results can be used to suppress SBS in high power lasers which could be useful in high bit rate signal transmission.
