In my book, A Programmer’s Introduction to Mathematics, I describe the Taylor Series as a “hammer for every nail.” I learned about another nail in the design of modern smartphone accelerometers from “Eight Amazing Engineering Stories” by Hammack, Ryan, and Ziech, which I’ll share here. These accelerometers are designed using a system involving three plates, which correspond to two capacitors.
Binary Search on Graphs
Authors: Kun Jeremy
Published: September 2024

Binary search is one of the most basic algorithms I know. Given a sorted list of comparable items and a target item being sought, binary search looks at the middle of the list, and compares it to the target. If the target is larger, we repeat on the smaller half of the list, and vice versa. With each comparison the binary search algorithm cuts the search space in half.

MLIR — Dialect Conversion
Authors: Kun Jeremy
Published: September 2024

Table of Contents In previous articles we defined a dialect, and wrote various passes to optimize and canonicalize a program using that dialect. However, one of the main tenets of MLIR is “incremental lowering,” the idea that there are lots of levels of IR granularity, and you incrementally lower different parts of the IR, only discarding information when it’s no longer useful for optimizations.
The ‘influence of Hall currents on unsteady-MHD heat transfer flow’ in a conducting channel containing two ionized fluids
Authors: Vangala Gowri Sankara Rao , TEMBURU LINGA RAJU
Published: September 2024

We delve into the ‘effects of hall currents on the dynamics of unsteady magnetohydrodynamic flow and heat transfer within a two-fluid system of ionized gases confined within a horizontal channel bounded by parallel conducting plates. Employing a regular perturbation technique, we solve the governing partial differential equations to unveil the distributions of velocity and temperature, alongside profiles depicting heat transfer coefficients. Through a systematic parametric analysis, we explore the interplay among variables such as the Hartmann number, Hall parameter, and ratios involving viscosities, heights, electrical conductivities, and thermal conductivities. The results highlight the profound influence of these parameters on the dynamics of unsteady magnetohydrodynamic (MHD) heat transfer within a flow regime characterized by a dual-ionized fluid’. This influence is particularly pronounced when the lateral plates of the channel are conductive. Significantly, elevated Hartmann numbers and Hall parameters are associated with augmented heat transfer coefficients at both plates, holding other variables constant.

Pregnant women who experience dangerous signs of pregnancy should immediately see the nearest health worker. If the health worker you meet is a midwife, the pregnant woman will receive emergency treatment and be immediately referred to the hospital for further treatment. Early detection of pregnancy complications can be used as an effort to prevent complications in pregnancy. The main problem at the Binanga Mamuju Community Health Center is that there are still many pregnant women who do not know the danger signs of pregnancy that they need to be aware of. Delay in detecting complications will be dangerous for the mother and fetus. The aim of this service is to increase pregnant women's knowledge about the danger signs of pregnancy. Method This activity was carried out using the counseling method, providing leaflets and discussions. Participants in this activity were 22 pregnant women at the Binanga Mamuju Community Health Center. To determine the effectiveness of this activity, participants were given a pretest and posttest to measure increased knowledge of the dangers of pregnancy. Evaluation Results The results obtained in this activity were that participants were very enthusiastic about following the counseling given and discussing so that there was an increase in knowledge as seen from the pre-test results from 7 (31.8) with good knowledge to 19 (86.4) with good knowledge about the danger signs of pregnancy. The success of this outreach was also due to the provision of attractively presented leaflets that used pictures and sentences that were easy for participants to understand. The results of this PKM assessment can be used as a benchmark for midwives that providing education in pregnancy about the danger signs of pregnancy is very important for the continuity of the mother's pregnancy.

The yield analysis of new maize hybrids at multiple locations could provide information on the their stability. The aims of the study were to identify the effect of genotype, environment, year and their interactions on yields of some new Romanian maize hybrids and to compare maize hybrids that have high and stable yields in diverse environments in Romania based on three method: parameters of regression, drought susceptybility index and coefficient of variation. We evaluated the stability of 17 maize hybrid in six different location from Romania. Maize hybrids with high yield potential and early maturity traits derived from a diallel cross were carried out in a randomized complete block design as a single factor with three replicates. The effects of environment, genotype, year and its interaction on yield were highly significant (P<0.01). Eight hybrids (Oituz, HSF 1191-14, HSF 3425-16, HSF 1034-17, HSF 1033-17, HSF 4075-17, HSF 3877-17 and HSF 7395-18) had yields that were higher than the average yield of all genotypes in all environments and were considered stable on the basis of two stability parameters, i.e., parameters of regression and coefficient of variation. Three of these hybrids are considered unstable on basis on drought susceptybility index. Thus, these three hybrids (Oituz, HSF 3877-17 and HSF 1033-17) could be targeted for these specific locations with low water stress. The drought susceptybility index highlight the maize hybrid HSF 1191-14 as the promising for high yield and instead presented the best drought tolerance in all years.
Percentages are a better format for conveying medical risk than frequencies
Authors: Weseley-Jones Eli , Mordechai Molly
Published: September 2024

For patients to make informed decisions about their health care, it is essential that they understand the risks associated with various treatments. However, risks can be framed in different ways, and past research has yielded conflicting results about which format is easiest for people to comprehend. Frequencies (e.g., 1 out of 4) and percentages (e.g., 25%) are common ways to communicate risk, and the goal of this study was to explore how these formats affected the comprehension of different numerical values. A sample of American adults (N = 141) was recruited via Amazon’s Mechanical Turk to take a survey on Qualtrics. Participants indicated their preference for frequencies or percentages and then answered a set of questions to evaluate their skill at working with the two formats when the values were small, large, complex, or simple. Participants reported equivalent comfort levels with risks framed as percentages and frequencies, but interestingly, they performed significantly better on questions asked using percentages than frequencies. These findings indicate that percentages should be used instead of frequencies when presenting risk information to patients, regardless of the size and complexity of the numerical value represented.

New, soft, chemical-resistant TPU for pneumatics with proportionate biogenic raw material content: Elastic sealing materials contribute significantly to the function, energy efficiency and service life of pneumatic cylinders and valves. These should be correspondingly soft, i.e. in particular smaller than 90 Shore A. Traditionally, thermoplastic polyurethanes compete with soft rubber materials, especially when it comes to meeting high-quality chemical requirements within this genre. Also to enable the important sliding properties required for energy efficiency. Rubber materials have so far been the first choice when it comes to higher temperature requirements and chemical resistance. The TPU grades available on the market are considered to be particularly susceptible to hydrolysis. Konzelmann GmbH has recently started to represent TPU materials that are tailored to pneumatic requirements. In addition to the high-quality physical property profiles, their special properties are primarily in the area of chemical resistance. These new materials are suitable for various types of pneumatic applications and can be flexibly adjusted in terms of Shore hardness. In addition to their exceptional chemical stability, these TPU materials were also certified to have outstanding cold properties. In this lecture, the targeted innovations in the TPU structure in contrast to commercially available TPU will be described and differentiated, thereby providing an explanation for this progress.

In the field of hydraulics, reciprocating rod and piston seals are crucial for the performance of cylinders and actuators. With respect to energy efficiency, leakage as well as product lifetime, numerical design tools play an important role in the design process of these seals. In recent decades, various numerical models for the prediction of tribological characteristics of reciprocating seals have been proposed. However, these models are often time-consuming to set up and come with long computation times. In recent years, advances in soft- and hardware have lead to the trend to solve complex elastohydrodynamic systems undergoing mixed lubrication within a single multiphysics platform. By coupling solid mechanics, surface mechanics and fluid mechanics using the direct method, mixed lubrication in elastohydrodynamic systems has been successfully modeled for axisymmetric O-rings. Building on this, the presented work explores a two-component sealing system using the COMSOL® Multiphysics platform, enabling comprehensive coupling of solid, surface, and fluid mechanics. The numerical model's validation involves a test rig measuring friction from reciprocating seals, 3D surface texture characterization of the sealing lip, and an application-oriented test apparatus to determine the coefficient of friction for the rod-seal contact pair. This study aims to validate the direct method for a multi-part elastohydrodynamic system, emphasizing experimental validation to assess the accuracy of mixed lubrication models.

The school garden program has been implemented as one of the efforts to address malnutrition among children. This analysis aims to evaluate the impact of the policy on students' nutritional status and its effectiveness in increasing nutritious food intake. The study involved data collection through surveys, interviews, and measurement of nutritional status before and after the implementation of the program. The results of the analysis show that school gardens have a positive impact in improving students' knowledge about nutrition and healthy eating. Students were directly involved in the process of planting and caring for the plants, which contributed to increased consumption of fresh fruits and vegetables. The program also plays a role in reducing the prevalence of malnutrition, with a significant increase in the weight and height of children involved in the school garden. However, the success of the program is influenced by several factors, including support from the school, parental involvement, and accessibility of resources. Constraints included budget limitations and lack of training for educators on how to effectively manage school gardens. To improve the effectiveness of the program, it is recommended that the policy be complemented with adequate training, stable financial support, and integration with the health education curriculum.Overall, school gardens are a promising strategy to address undernutrition

This study is based on the construction of a education system with "moral education first, five education integration". It aims at the training requirements of "chief engineer type" talents at Northwestern Polytechnical University, and summarizes the previous teaching practice work experience and student management service work experience. On the basis of analyzing the specific problems faced by the construction of undergraduate classes in universities and the difficulties that may arise in the process of integrating the five educations, more targeted work ideas are condensed in this research. This study focuses on the basic organizational unit of university classes, with taking a basic class of the School of Power and Energy as the specific work object, to carry out the construction of a class level "moral education first, five education integration" platform, as well as to explore the practical cultivation of "chief teacher type" talents.This study enables students to become discoverers, participants, and promoters of innovative activities, thereby becoming beneficiaries of the cultivation of "chief engineer type" talents, enabling the research results to truly promote class construction.

INTRODUCTION. Evidence in child abuse cases can be scarce and is often centred around the child’s testimony. However, child testimony varies with the child’s development. Here, an overview of suspects, case decisions and court verdicts from a cohort of children is presented, stratified across children aged 0-3, 4-7, 8-11, and 12-15 years. METHODS. Children seen at the Department of Forensic Medicine, Aarhus University, Denmark, in 2001-2013 were analysed, including all case files from the police, courts and healthcare services. RESULTS. A total of 647 cases were presented. The most frequent suspect was the child’s parents. The police referred to the prosecutor in 69% of all cases, and 37% were tried in court. The lowest proportion of cases of tried cases was found among children aged 0-3 years (20%) and the highest among children aged 8-11 years (57%). Across ages, no corroborating evidence, the accused’s refusal of guilt and no case to pursue (insufficient strong evidence) were the most frequent reasons for case closure. Cases relating to children aged 0-3 years were frequently dismissed because the fault could not be placed, whereas cases relating to children aged 12-15 were frequently rejected because of lacking evidence of compulsion (non-consent). CONCLUSION. Results show variations across ages regarding children tried in court and case dismissal. A dedicated child court may be considered to ensure equal access to justice. Questioning during the forensic examination and the use of psychologists may strengthen the available evidence. FUNDING. These materials have received financial support from the Danish Victims Fund.

Published: September 2024

We present a rare case of an 84-year-old woman with a left atrial chorda. She was admitted with heart failure and echocardiography revealed severe mitral valve insufficiency due to chordal rupture and prolapse of the posterior leaflet. In addition, a left atrial chorda was diagnosed, attached to the anterior leaflet, restricting the valve and contributing to the insufficiency. The patient underwent surgery with the removal of the atrial chorda and insertion of two neochordae and mitral annuloplasty with a ring. Postoperative echocardiography showed a well-functioning valvuloplasty.
