Abstract

Pap-smear images can help early detection of cervical cancer, but the manual interpretation by a pathologist can be time-consuming and prone to human error. Semantic segmentation of the cell nucleus and cytoplasm plays an essential role in Pap smear image analysis for the detection of cervical cancer automatically. This study proposes a modified U-Net architecture by adding batch normalization to each convolution layer. Batch normalization aims to stabilize and accelerate the convergence of the model during training, thus overcoming the vanishing gradient problem. The modified U-Net model achieves high accuracy and low loss during the training process, indicating its ability to learn and recognize patterns in the data. The performance evaluation of the model resulted in 91.4 % accuracy, 79.9 % sensitivity, 87.7 % specificity, 81.7 % F1-score, and 83.7 % precision. The results show that the proposed modification of U-Net architecture with batch normalization improves the segmentation performance for cervical cancer cells in Pap smear images. However, improvement in architecture is still required to increase the ability to overcome overlapping areas between the nucleus, cytoplasm, and background.

Abstract

The local elections with a single candidate elections to elect regional heads who followed only one pair of candidates only / single candidate. This study aims to determine how the voting mechanism in the implementation of the local elections with a single candidate against the order of the Constitutional Court Number 100 / PUU-XIII / 2015. In thisĀ  study the authors will solve the problem regarding the enactment of a new voting mechanism in the implementation of the local elections with a single candidate. This research is a normative legal or commonly called the doctrinal legal research done by researching library materials or secondary data consists of primary legal materials, secondary law and tertiary legal materials. Primary legal materials consist of legislation, notes the official records, the minutes in the making of legislation and the decision of the judge's decision. As for the secondary law in the form of all the publicity about the law which is not an official documents. The results of research and discussion to explain that after the decision of the Constitutional Court Number 100 / PUU-XIII / 2015 there is a new mechanism of voting in local elections with a single candidate by selecting "agree" or "disagree" on a single candidate head area.
