Zinc sulfide (ZnS) thin films were deposited on glass substrates using the spray pyrolysis technique (SPD) with different precursor concentrations (10-4 to 10-1M). The structural, morphological, compositional, and optical properties were investigated using X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), and UV-Vis spectroscopy. XRD results revealed a transformation from amorphous to crystalline cubic ZnS structure with increasing precursor concentration. FESEM and AFM analyses showed that higher concentrations produced smoother surfaces with smaller particle sizes. EDX confirmed i

Several Intrusion Detection Systems (IDS) have been proposed in the current decade. Most datasets which associate with intrusion detection dataset suffer from an imbalance class problem. This problem limits the performance of classifier for minority classes. This paper has presented a novel class imbalance processing technology for large scale multiclass dataset, referred to as BMCD. Our algorithm is based on adapting the Synthetic Minority Over-Sampling Technique (SMOTE) with multiclass dataset to improve the detection rate of minority classes while ensuring efficiency.
