A Cayley graph is a graph of a group that is build based on a specific subset of the group. The vertices of the graph are the elements of the group, and two different vertices, x and y are adjacent if the product of x and inverse of y is in the subset. One type of Cayley graph recently introduced is the prime power Cayley graph in which the subset of the group considered in constructing this graph contains the elements dividing the order of the group. In this paper, we construct all possible prime power Cayley graphs based on the subsets for the cyclic group of order pq where p and q are primes. The results show that there are seven possible prime power Cayley graphs for this group. [ABSTRACT FROM AUTHOR]

A Cayley graph of a group is a graph associated with the generating subset of the group. Meanwhile, a pi-Cayley graph is a variation of the Cayley graph where pi is a prime dividing the order of the group. The pi-Cayley graph is focused on the subset that contains the elements with prime power order. In this paper, two graphs are constructed for a cyclic group of order st, namely the s-Cayley graph and the t-Cayley graph where s and t are primes. [ABSTRACT FROM AUTHOR]

How to accurately direct a mobile robot to follow a certain path is the main problem with line follower robots. The design and execution of an intricate line follower mission are demonstrated in this research using Matlab Simulink. Using software that simulates the motion of a mobile robot along a complex path, the proposed line follower algorithm and the offered PID controller are developed and evaluated. Due to the difficulty in selecting the PID controller's settings, the Particle Swarm Optimization (PSO) approach is utilized to choose and optimize the parameters of the constructed PID controller. Three IR sensors are used to collect data on the mobile robot's position in respect to the intended path. The yaw rate of the mobile robot will be controlled to maintain it on the planned route by changing the speed of the actuators. The simulation findings show that a mobile robot's mobility may be maintained even when undertaking complex maneuvers. The hardware design of the robot system is completed using the mobile robot. The real-world results show that a mobile robot and a simulation function almost identically.

Over the past two decades, mobile robots have become one of the most important modern technologies and have attracted substantial interest in various applications. A mobile robot cannot know where it is without localization, which makes it vulnerable to going missing. The two types of localization techniques are relative and absolute, respectively. The representative of relative positioning techniques is a dead reckoning. The movement of the wheels and the starting location is used to determine the position of a mobile robot. Its advantages include low cost, simplicity, quick response times, and real-time operation. To measure the effectiveness of the dead reckoning approach, laboratory simulations and experiments on mobile robots were conducted. The mobile robot is made using a microcontroller Arduino Uno. Sensors and actuators use materials that are affordable and easily available in the market. Kinematic models are used to construct proportional and differential controllers (PD) mobile robots. The mobile robot's location and heading inaccuracy relative to the target posture is used to calculate the controller performance. Experimental and simulation findings demonstrate that the mobile robot can reach the appropriate posture. [ABSTRACT FROM AUTHOR]

Mataraman Java is one of the regions in western East Java. This region is an area that was once included in the Mataram kingdom. In this region, there is still a culture of parents giving advice to their children using sentences with deep meaning, so that the advice sentences are often stigmatized as a myth. In fact, if studied more deeply, many of the advice sentences that are often considered myths are facts. So it can be said that not always the advice given by parents for generations is just a myth. The problem in this study is the fading values of Javanese parental advice, because many people think that the advice cannot be trusted or is considered a myth. Therefore, there is a need for a deeper study related to the meaning of advice that is often stigmatized by the community as a myth. Javanese parents' advice has moral values that are important to preserve. If the stigma of myth on the advice is still valid today, then the true meaning of the advice will be lost. The purpose of this study is to find the meanings of advice utterances that have been passed down from generation to generation by parents to their children who are often stigmatized as myths. This research was conducted with a qualitative approach, with data collection methods of interviews, and data analysis stages in the form of data reduction, data display, and conclusion drawing. The results of this research are 1) Many of the advice (wewaler) of old parents are actually still used today. The use of this advice is unconsciously uttered when children do something that is deemed inappropriate with the manners that exist in the area. 2) Wewaler consists of two parts, the first part is an advice/prohibition not to do something, and the next part is a more emphasized sentence such as the consequences/impacts if the prohibition in the first part is violated. The addition of the second part of the sentence in the wewaler makes the advice of Javanese parents stigmatized as a myth that is not proven to be true. [ABSTRACT FROM AUTHOR]

Behavioral biometric traits are not fully distinguished in recognition tasks, but they can improve the overall performance of biometric recognition systems by adding them. The behavioral biometric studied in this paper is related to keystroke dynamic. This paper examines the touch keystroke dynamics of computer users for the purpose of identifying their culture by using four different SVM kernels. It has been confirmed that racial classifications can be made by gathering keystroke data from 250 respondents representing various culture in Malaysia. Results show that different culture categories display different typing patterns. The classification is made using four SVM kernels and a comparison of the accuracy results is shown. The four kernels are Linear, Quadratic, Cubic and Fine Gaussian. The linear kernel has provided the highest accuracy and consistent readings compared to other kernels for the four features evaluated for dynamic keystrokes, namely press-press time, release-release time, press-release time and release-press time. The linear kernel has the highest accuracy reading of 92.4% for classification using press-press time features for the Malay vs Chinese category. [ABSTRACT FROM AUTHOR]

According to a 2010 study, cervical cancer affects women all over the world and is the fourth most common disease among women after lung, colorectal, and breast cancer. Numerous studies are being conducted to improve pre-cancer screening methods. It is challenging for doctors to collect correct data due to inconsistent and unsystematic analysis techniques. Making a determination just from eye inspection is challenging. It is probably erroneous based on the sample of microscopic images studied. This is because to the blurring, noise, shadow, lighting, and artefact issues that can damage a microscopic image. This study has modified Bradley's binarization method in order to improvise nucleus detection on pap smear image. The modification method has performance that overcome other methods which is Bernsen, Bradley, Feng, Niblack, Nick, Otsu, Sauvola and Wolf. The analysis indicate modification method has value 75.03% on Fmeasure, 92.78% on accuracy, 13.61 on PSNR and 0.086 on NRM. This study helps the modification method inspired by Bradley shows an improvement in segmenting nucleus region. [ABSTRACT FROM AUTHOR]

The use of behavioural biometrics, such as movement patterns and keystroke dynamics, in human identity recognition research to strengthen smartphone security is growing. Users usually secure their phones with a PIN or pattern. This paper uses a smartphone keystroke dynamic open dataset with user age information. This Open Dataset is known as the RHU-Keystroke Dynamics dataset. A dataset classification study was conducted utilising the Weighted K-nearest neighbour (W-KNN) method in order to identify the three age categories with the highest accuracy. The four keystroke features that have been collected in this open dataset are used for this classification. The highest average accuracy obtained from this W-KNN method is 83%. The results of the study are explained with a Confusion Matrix diagram and a Receiver Operating Characteristic (ROC) graph. A classification study using this method has successfully increased accuracy and can be utilized in the use of software, as demonstrated in the results of the study. It is expected that future studies will apply other classification methods to keystroke dynamics. [ABSTRACT FROM AUTHOR]

Online shopping has become an alternative way for people in buying things, especially in the middle of the novel coronavirus (COVID-19) outbreak crisis. Besides, it is also making life easier. The problem with online shopping is when sometimes customer could not able to receive the goods when nobody at home. And it also involved safety considerations as in normal case, the good will be left outside the premises by the courier when the recipient not at home the good might be stolen. This paper aimed to design a Smart Home Package Mailbox to secure the delivery packages receive safely with good condition by reducing the problems occurring during the delivery. The Smart Home Package Mailbox is a hardware that operates by using the Quick Response (QR) code to communicate with its system. It has two compartments level which levels two for receiving package and level one for storing the received packages. Two main android applications have been developed to support the project system. The Smart Postman application is for the postman to open the mailbox door and update data in the database. While Smart Home Mailbox application is for users to track the delivery and receive notification. Once the sending package is put inside the mailbox, the sender and the recipient will be notified regarding the delivered package. This project is able to increase courier management efficiency as well as packages being delivered within expected time with good condition. [ABSTRACT FROM AUTHOR]

Extension workers have the task of encouraging farmers to change their way of thinking, working, and living by the times and agricultural technology. This study aims to determine the competence of extension workers in increasing the productivity of Bali cattle in Tanggetada District, Kolaka Regency which was carried out from April to September 2022. The study used a survey method that was determined purposively because Tanggetada District is the location of Bali cattle farms with the second largest population in Kolaka Regency with 114 research informants divided into 12 extension workers and 102 breeders, then analyzed descriptively. The results of the study revealed that as many as 12 extension workers had good performance while breeders (respondents) still had many obstacles in increasing livestock productivity, maintenance, feed, disease, and sources of Bali cattle seeds. These findings can be used as a reference for local governments in optimizing the performance of extension workers to increase the productivity of Bali cattle in Tanggetada District, Kolaka Regency.

The potential organic cross-talk of gut-lung and complex pathways including their corresponding microbiota have emphasized the existent of a gut–lung axis (GLA). Evidences considered the indispensable role of inter-kingdom crosstalk in maintaining host homeostasis by shaping local cell function, immune responses, and intercede the course of respiratory diseases, including pulmonary tuberculosis infection (PTB). A significant decrease of gut microbiota species number and diversity in TB patients compared to healthy group has conveyed that the gut microbiota may impact on M. tuberculosis (MTB) infection. In this review, we will provide an overview of the possible functional part of the gut microbiota in TB immunity and its role as the host-microbiota directed therapy (HMDT) in TB management. The literature search of this review was conducted using PubMed and Google Scholar with specific terms and no specification of article publication time. Microbial-host immune interaction in TB infection studies and potential use of microbial-based therapy in TB are listed and described. In sum, further researches are needed to identify strain-specific effect, gut microbiota anti-tubercular mechanism, and the role of other non-bacteria kingdom in immune function and disease.
