One of the biggest and most favourable electronic device technologies for printable and flexible electronics is the organic thin film transistor. However, designing large-scale integration circuits remains difficult due to device uniformity. Although semiconductor layer technology has advanced, the quality of the dielectric layers is similarly essential. Leakage current and transistor size are the main factors which impact the electronic device. However, leakage current occurs due to the reduction of dielectric material that affects the parameters like threshold voltage, capacitance and transconductance. To overcome the aforementioned drawbacks, the bi-polymer layers based on squid optimization with the dielectric medium is proposed. Bi-polymers such as PEI-EP (polyetherimide–epoxy polymer), POM-H (polyoxymethylene homopolymer) and SiO({}_{2}) is utilized as trilayer dielectric material in this proposed method to reduce the leakage current and act as insulator. Squid game optimization is applied to optimally select the dielectric thickness to perform better performance in the device. Electrical measurements such as (I{-}V), transfer characteristics, mobility ((mu)) and capacitance (pF) are used to evaluate the performance of the device. The obtained electrical characteristics are mobility as 355 cm({}^{2}) V({}^{-1}) s({}^{-1}) and capacitance value as 7.00 pF are compared with the existing dielectric materials. The experiment shows that the simulation and modelling of the proposed method performs better than the other existing dielectric medium.","PeriodicalId":44919,"journal":{"name":"Optoelectronics Instrumentation and Data Processing","volume":"63 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141169502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some overlook the importance of studying complex statistical coefficients and their role in comparing the results of optical designs and realize how important information is in analyzing data. In statistics, one can learn various techniques for working with data. This paper goes into a detailed study of multilayer stacks’ dispersive properties for two mirror designs depending on MATLAB programs based on statistical parameters to evaluate the reflectance for the ZnS/MgF({}_{2}) mirror. Two samples with a quarter wavelength optical thickness were prepared, specially designed for 632.8 nm He-Ne laser mirrors. For the designed mirror, the value of the reflectivity of the thirteen-layer ZnS/MgF({}_{2}) mirror is 99.34(%), while for the seven-layer ZnS/MgF({}_{2}) mirror is 96.57(%). This study presents greater detail on statistics and realized data topics when designing multilayer coating, including mean, median, mode, and standard deviation (STD). The reliability and accuracy of the data can be verified by calculating the standard deviation.","PeriodicalId":44919,"journal":{"name":"Optoelectronics Instrumentation and Data Processing","volume":"19 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140887867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important to note that the field of brain tumor analysis has effectively applied medical image processing techniques, particularly on MR images, to automate crucial procedures including extraction, segmentation, and classification for tumor detection. Computer-aided diagnostic techniques are getting harder to employ and yet have many unresolved issues since tumors can vary in their sizes, locations, and shapes. More research has been centered on the noninvasive imaging capabilities of MRI. As a result, electronic methods are used to diagnose brain malignancies. One of the most popular and commonly used electronic methods for detecting brain cancers is magnetic resonance imaging (MRI). Hence, the MRI brain image based brain tumor model has been designed using the modified Mask R-CNN. In this designed model, Van Cittert algorithm is used for pre-processing the brain tumor MRI images to deblur and improve the quality of the gathered input images. The preprocessed data are segmented using Mask-KRCNN, which divides recognized objects into their pixel-level segments. The KNN classification technique may be used to train the Mask R-CNN algorithm to handle overlapping objects with multiple classes. Accuracy, error, sensitivity, specificity, precision, FPR, FNR, F1-Score, MCC, Kappa, MK, FM, NPV, FOR and FDR are some of the performance metrics for this designed model. The attained performance metrics values for the proposed model are 96, 4, 93, 98, 93, 1, 6, 93, 95, 94, 86, 93, 98, 2, and 2(%). Thus, the modified mask R-CNN with KNN algorithm primarily based on segmentation and type for prediction of brain tumor types plays better than the existing version.","PeriodicalId":44919,"journal":{"name":"Optoelectronics Instrumentation and Data Processing","volume":"43 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140569819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The appearance of laser generation is caused by the fact that the probability of stimulated emission in the red wing of the spectral line exceeds the probability of absorption if homogeneous broadening due to interaction between active particles and the buffer gas significantly exceeds the natural broadening (under high pressures of the buffer gas). Analytical formulas representing the operation of a transversely diode-pumped alkali metal vapor laser are obtained. It is found that cesium atoms are the most promising object for observation of laser generation without population inversion in the red wing of the (D_{1})-line of alkali metal atoms. In a sufficiently long active medium (the length of the medium is 50 times its width), the efficiency of pumping radiation conversion into laser radiation can reach 57% at a buffer gas pressure of 5 atm, a pump diode radiation intensity of 5 kW/cm({}^{2}), and a half-width of its spectrum of 1 cm({}^{-1}). The laser radiation frequency can be tuned by several tens of cm({}^{-1}).","PeriodicalId":44919,"journal":{"name":"Optoelectronics Instrumentation and Data Processing","volume":"18 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140300379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
