- Data are the raw facts, the material for obtaining information. Information is an increment in knowledge: it contributes to the general framework of concepts and facts we know. The information relies on the context and the recipient's general knowledge for its significance, i.e., output after data has been processed. Information systems (including networked and distributed systems) use data stored in computer databases to provide needed information. A database is an organized collection of interrelated data reflecting a major aspect of a firm's activities. Quality information (data) needs to possess several attributes such as Timely, Complete, Concise, Relevant, Precise, and Form (The level of detail, tabular versus graphic display, quantitative versus qualitative form, and relies upon either Internal or External situations). Failure to meet those attributes can result in a catastrophic impact. That is why we propose a formulation of the mathematical model to measure and predict the data reliabilities in networked and distributed systems. The proposed model discussed depends on general control, application control, and user control, whether internal or external, as well as techniques employed to ensure that data are accurate, complete, relevant, and valid.

- High doses of ionizing radiation [X-ray] received by patients can lead to adverse health outcomes such as cancer induction and other biological complications in patients. The extensive demand for X-ray examinations, an increase in the number of X-ray facilities and few radiation researches conducted in Kebbi State led to the conduct of this research. The X-ray doses received by Sixty nine (69) adult patients with a total of 8 from Sir Yahaya Memorial Hospital (SYMH) and 61 patients from Federal Medical Centre (FMC), Birnin Kebbi were analyzed using CAL DOSE_ X 5.0 version software by entering the patients' data (Age, Sex) and exposure parameters such as focus to detector distance (FDD), miliampere second (mAs)

- The main function of Custom Power Devices (CPDs) is to provide Quality Electrical Power per the customer’s requirements in the distribution system. For this purpose, CPDs are connected to medium or low-voltage level distribution systems with high-speed power electronic converters/static controllers. In this paper, a CPD called GUPQC consisting of three voltage inverters connected to a common DC-link energy storage capacitor is used in the three-bus distribution system to address power quality issues. The GUPQC simulation model in a single-phase system is simulated in MATLAB. The p-q theory control strategy is used to obtain the required compensating signal to compensate for harmonics of load current at bus-1, and the UVT control strategy is used to generate compensating signal to mitigate the voltage variations during voltage sag / swell at the source bus.

- Electrical Power Quality (EPQ) is fetching more of a concern as smart grid technology advances in distribution systems. A proposal for MT-UPQC integration in a microgrid system (G) is presented here. This paper presents configurations of UPQC, MT-UPQC, UPQCµG and MT-UPQCµG and a comparison between them. MT-UPQCµG combines the advantages of both MT-UPQC and UPQCµG. The MT-UPQC can correct voltage quality issues, harmonic currents and reactive currents in a variety of ways depending on the needs of the user. On the MATLAB Simulink platform, a 3T-UPQCµG microgrid is constructed for simulation and verified the same. The obtained results of the simulation suggest that the proposed method is both effective and adaptable.

- The orthogonal frequency division multiplexing (OFDM) method was the most well-known and attractive technique utilized in wireless communication for large-scale data transfer at a high rate. OFDM has been widely employed as a more effective multicarrier modulation approach in various radio frequency wireless communication standards. But the drawback of OFDM is high Peak-to-Average Power Ratio (PAPR) and low Bit Error Rate (BER) performance. These problems can be overcome using a multicarrier filter bank with an offset quadrature amplitude modulation (FBMC/OQAM) system. For PAPR minimization in high-speed wireless communication systems, effective approaches are required. An effective technique to lower the PAPR is partial transmit sequence (PTS). In this paper, a PTS based on the Swarm Intelligence Grey Wolf Optimization method (PTS-SIGWO) is suggested and used in the FBMC/OQAM system to minimize the PAPR and increase the BER performance. In this paper, the subcarrier phase factor search in the PTS technique is enhanced by implementing a meta-heuristic algorithm called GWO. The suggested GWO achieves nearly optimal performance with a less number of iterations by balancing the exploration and exploitation phases when searching for peak power carriers. The simulation results are generated using the MATLAB tool. The results of the suggested technique demonstrate that PAPR and computational complexity have been effectively reduced, and BER performance has increased compared to other techniques. The proposed method has a PAPR of 3.3dB; other methods require more than 4dB to achieve a CCDF of 10 -3 .

- This study aims to determine the chlorophyll content and chlorophyll dye on the nano TiO 2 electrode morphology. Color variations and good chlorophyll storage are dyes for coloring Nano TiO 2 electrodes on solar cells. The ingredient for making chlorophyll is the leaves of the Syzygium paniculatum plant. To prove that red shoot leaves' chlorophyll content is high, we will compare it with papaya leaves (Carica papaya) and cassava leaves (Manihot utilissima). This experiment uses a variation group with three experimental variables. The first variable is the variation of Syzygium paniculatum leaves with red color, green color, and a 50% red and 50% green mixture, as a comparison using cassava leaves and papaya leaves. The second variable is the solvent composition consisting of distilled water: chloroform: and 96% ethanol. The first solvent composition, in sequence, namely 3: 2: 1, and the second solvent composition, namely 3: 2: 1.5. The third variable is the storage time, 24 hours, 18 hours, and 12 hours. The results observed were chlorophyll levels, chlorophyll b levels, total chlorophyll levels, and the Nano TiO 2 electrode with chlorophyll dye. The results showed that leaf color and solvent composition significantly affect chlorophyll content and the electrode coating morphology. The results showed that the green leaf color and the 3: 2: 1,5 solvent compositions had the highest chlorophyll content, namely chlorophyll-a of 32.548 mg/L, chlorophyll b of 56.327 mg/L, and total chlorophyll of 88.750 mg/L. Moreover, the morphology with EDX analysis showed C, O, Ti, and Mg at 12 hours of storage. This study recommends using green leaf color from Syzygium paniculatum leaves with a solvent composition of 3:2:1.5 for DSSC.
