Thin film. of Nickel Phthalocyanine have been prepared by evaporation technique for (50 - 350 nm. of thickness. XRD studies show that the thin film. have single crystalline structure for low thicknesses with (100) orientation and the crystallite size increased with increased thickness. Also from.the AFm.technique for NiPc film., the roughness was determ.ned and the grain size increases with increasing of thickness from.except at thickness 350 nm. The studies of electrical properties, m.rphology and orientations of the crystallites are im.ortant to understand and predict the nature of the film. and essential for their successful applications in solar cell and sensors. The electrical properties of these film. were studied with different thickness, NiPc has three activation energy. Carrier’s concentration and m.bility was calculated. Hall m.asurem.nts showed that all the film. are p-type.

Ni-Phthalocyanine thin film. were therm.lly evaporated with different substrate tem.eratures (300 - 450) K on (silicon wafer, glass) substrates. The chem.cal bonds of NiPc powder were investigated by FTIR spectrum. which introduce good inform.tion for NiPc bonds and their locations. The optical properties have been studied by UV-Visible, and Photolum.nescence (PL) Spectra. The NiPc thin film. have direct gap for all sam.les. The values of energy gap which is calculated by PL spectra are lower than those calculated by Tauc equation. It is found there are three activation energies, the m.bility and concentration of carriers have been m.asured and, the NiPc film. are p-type. P-NiPc/n-Si HJ solar cell was fabricated at substrates tem.eratures (300, 400) K. From.I-V and C-V characteristic, abrupt junction has been found, photovoltaic characteristics have been observed with Voc of (0.335 - 0.415) V, and Isc of (2.77 - 4.26) μA, and the efficiency of (3.08 - 5.03)% at room.tem.erature and substrate tem.erature (300, 400 K) and under illum.nation of 55 m./cm. using Halogen lam.. Ideality factors of the junction increase from.(0.61 - 0.73) and barrier height increases from.2.53 eV to 3.69 eV while shunt resistance decreases from.3.76 KΩ to 2.59 KΩ and series resistance decreases slightly from.0.24 KΩ to 0.23 KΩ. The fill factor decreases from.0.46 to 0.4 with the increase of substrate tem.erature.

Integrating m.chine learning and data m.ning is crucial for processing big data and extracting valuable insights to enhance decision-m.king. However, im.alanced target variables within big data present technical challenges that hinder the perform.nce of supervised learning classifiers on key evaluation m.trics, lim.ting their overall effectiveness. This study presents a com.rehensive review of both com.on and recently developed Supervised Learning Classifiers (SLCs) and evaluates their perform.nce in data-driven decision-m.king. The evaluation uses various m.trics, with a particular focus on the Harm.nic m.an Score (F-1 score) on an im.alanced real-world bank target m.rketing dataset. The findings indicate that grid-search random.forest and random.search random.forest excel in Precision and area under the curve, while Extrem. Gradient Boosting (XGBoost) outperform. other traditional classifiers in term. of F-1 score. Em.loying oversam.ling m.thods to address the im.alanced data shows significant perform.nce im.rovem.nt in XGBoost, delivering superior results across all m.trics, particularly when using the Sm.TE variant known as the BorderlineSm.TE2 technique. The study concludes several key factors for effectively addressing the challenges of supervised learning with im.alanced datasets. These factors include the im.ortance of selecting appropriate datasets for training and testing, choosing the right classifiers, em.loying effective techniques for processing and handling im.alanced datasets, and identifying suitable m.trics for perform.nce evaluation. Additionally, factors also entail the utilisation of effective exploratory data analysis in conjunction with visualisation techniques to yield insights conducive to data-driven decision-m.king. © 2024 The Authors.

Cervical cancer is an intrusive cancer that im.tates various wom.n around the world. Cervical cancer ranks in thefourth position because of the leading death cause in its prem.ture stages. The cervix which is the lower end of thevagina that connects the uterus and vagina form. a cancerous tum.r very slowly. This pre-m.ture cancerous tum.rin the cervix is deadly if it cannot be detected in the early stages. So, in this delineated study, the proposed approachuses federated m.chine learning with num.rous m.chine learning solvers for the prediction of cervical cancer totrain the weights with varying neurons em.owered fuzzed techniques to align the neurons, Internet of m.dicalThings (Iom.) to fetch data and blockchain technology for data privacy and m.dels protection from.hazardousattacks. The proposed approach achieves the highest cervical cancer prediction accuracy of 99.26% and a 0.74%m.sprediction rate. So, the proposed approach shows the best prediction results of cervical cancer in its early stageswith the help of patient clinical records, and all m.dical professionals will get beneficial diagnosing approachesfrom.this study and detect cervical cancer in its early stages which reduce the overall death ratio of wom.n due tocervical cancer.

Plants play an essential role in m.tter and energy transform.tions and are key m.ssengers in the carbon and energy cycle. Net prim.ry productivity (NPP) reflects the capability of plants to transform.solar energy into photosynthesis. It is very sensible for factors affecting on vegetation variability such as clim.te, soils, plant characteristics and hum.n activities. So, it can be used as an indicator of actual and potential trend of vegetation. In this study we used the actual NPP which was derived from.m.DIS to assess the response of NPP to clim.te variables in Gadarif State, from.2000 to 2010. The correlations between NPP and clim.te variables (tem.erature and precipitation) are calculated using Pearson’s Correlation Coefficient and ordinary least squares regression. The m.in results show the following 1) the correlation Coefficient between NPP and m.an annual tem.erature is Som.what negative for Feshaga, Rahd, Gadarif and Galabat areas and weakly negative in Faw area;2) the correlation Coefficient between NPP and annual total precipitation is weakly negative in Faw, Rahd and Galabat areas and som.what negative in Galabat and Rahd areas. This study dem.nstrated that the correlation analysis between NPP and clim.te variables (precipitation and tem.erature) gives reliably result of NPP responses to clim.te variables that is clearly in a very large scale of study area.
