Integrated Machine Vision System for Evaluating Hole Expansion Ratio of Advanced High-Strength Steels

In this paper, we propose a new method to estimate the hole expansion ratio (HER) using an integrated analysis system. To precisely measure the HER, three kinds of analysis methods (computer vision, punch load, and acoustic emission) were utilized to detect edge cracks during a hole expansion test. Cracks can be recognized by employing both computer vision and a punch load analysis system to determine the moment of crack initiation. However, the acoustic emission analysis system has difficulty detecting the instant of crack appearance since the magnitude of the audio signal is drowned out by noise from the press, which interrupts the differentiation of crack configuration. To enhance the accuracy for determining the HER, an integrated analysis system that combines computer vision with punch load analysis, and improves on the shortcomings of each analysis system, is newly suggested.

DETERMINATION OF THE NORMS OF FREQUENCY-TERRITORIAL DIVERSION DURING THE DEVELOPMENT OF 5G TECHNOLOGY IN 3,4–4,2, 4,4–5, 14,5–15,35 GHZ FREQUENCY RANGES

The article presents scientific and technical proposals on the possibility of joint use of radio frequency spectrum of the fifth-generation mobile radio communication means and existing departmental radio-electronic facilities. On the basis of the load analysis, using the method of theoretical assessment of electromagnetic compatibility, the norms of territorial diversion between radio means are obtained. On the basis of the results of the calculations, it is possible to determine the subbands in which the joint use of radio means is possible, subject to optimization of the frequency-territorial plan and implementation of technical and organizational measures to ensure electromagnetic compatibility.

Analysis of the External and Internal Load in 5vs5 Large Sided Games: Differences Between Different Sized Fields

The study purpose. The purpose of the study is to analyze and understand the internal and external load in Large Sided Games (LSG) exercises carried out on fields of different sizes, defined as Small – Large Sided Games (SLSG) and Big – Large Sided Games (BLSG), according to the different square meters assigned to each player. Materials and methods. 22 professional soccer players (average age: 23.59 ± 4.87 years, weight: 77.8 ± 7.6 kg, height: 183.5 ± 7.5 cm, age training: 13.1 ± 1.7). The LSG exercises were carried out on a 60 x 54 m field (270 m2/player), defined as "small" (SLSG) and on a 65 x 60 m field (325 m2/player) defined as "big" (BLSG). During the two LSG exercises, the internal load and the external load were analyzed. LSG exercises were performed with 4 sets of 5 minutes each, with 2 minutes of passive recovery between each set. Results. The results of the internal load analysis show how the LSG carried out on a SLSG field provides higher and more significant HR values (p < 0.0005) than those emerged during the exercise carried out on a BLSG field. The RPE value is also higher during the SLSG, although statistically no significant difference appears. The analysis of the external load in relation with the observed parameters shows higher values in the BLSG, except for the number of accelerations. Conclusions. In terms of external and internal load, the results of this study showed how the difference of 55 m2/player can radically change the configuration of the two exercises. These differences allow to use both dimensions within a micro-cycle, but in sessions with different goals. The most appropriate sessions for LSGs are the first post-match session in which the rest day is not gone and the fourth session 3 days before the match.

Dot the pill down: Investigating the linguistic needs of foreign rugby players and lexicon of spoken rugby discourse

<p>Traditionally a sport which is played predominantly in English speaking countries such as New Zealand, England, and Australia, rugby is gaining in popularity in other countries such as Japan. International rugby competitions, such as the World Cup and Super Rugby, and increased migration of players and coaches in the sport contribute to this growth. In rugby, spoken communication with community members such as players, coaches, managers, and the referee, is a fundamental aspect of the sport. This communication presents a challenge for second language (L2) learners wanting to immerse themselves in a foreign rugby setting, in the case of Japanese players coming to New Zealand or New Zealand players going to Japan. It also presents a challenge for English for Specific Purposes (ESP) teachers who might be faced with developing courses and materials to help second language speakers learn what they need to know to play rugby in another language, and in another country. To date, no research has focused on the linguistic and communicative needs of these players. A feature of this communication is technical language, for example ruck, maul, and lineout, but no previous research has focused on the specialised vocabulary of this game. This thesis explores two aspects in the rugby domain: vocabulary, especially technical vocabulary, and the linguistic needs of foreign players and coaches in New Zealand and Japan. The study consists of two phases which were conducted to address these gaps in the research. To find out more about the nature of vocabulary in spoken rugby, phase one contained two parts. The first part was a corpus-based analysis of television commentary and team-based rugby speech. This analysis included conducting a lexical profile and vocabulary load analysis. The findings were compared to a written corpus, containing the Laws of Rugby. The results of the vocabulary profile analysis showed that high frequency vocabulary make up the majority words in each corpora. Additionally, other lexical items such as marginal words (e.g. fillers and swear words), as well as proper nouns, are important for comprehension, depending on the type of discourse. The vocabulary load analysis found 4,000 word families plus four supplementary lists and a rugby-specific list were needed for 98% comprehension in spoken rugby discourse. Part two of the first phase investigated the nature of technical vocabulary in rugby discourse. Four single-word and multi-word unit word lists using the spoken and written corpora were developed for use in the language classroom. A total of 293 spoken and 250 written word types were selected from the corpora following frequency and semantic meaning principles to create the technical single-word lists, for example lineout, tighties, and loosies. The technical words provided 12.04% and 35.41% coverage of the corpora from which they were developed. Next, lists of technical multi-word unit lists with 223 spoken and 417 written units, such as over the ball and lineout players, were created to be used in conjunction with the technical single-word lists. Phase two of the study utilised the results from phase one to conduct a linguistic needs analysis in New Zealand and Japan. Drawing on online surveys and semi-structured interviews, the results showed language difficulties occur throughout the rugby domain, especially when playing and practising the sport. Furthermore, general and rugby vocabulary are the two main language aspects affecting communication for both players and coaches. These findings indicate explicit instruction in spoken language is needed for L2 learners. This thesis has methodological implications for research into spoken technical vocabulary, as well as pedagogical implications for ESP. For example, the word lists can be used to help L2 rugby players and coaches learn the vocabulary that they will encounter and be expected to use fluently in games and at practice. This means they can receive specialised support for their language needs and ultimately be able to perform at their highest level in the foreign rugby community.</p>

PT XYZ merupakan perusahaan yang menyediakan berbagai jenis pipa air dan sambungan (fitting) beserta lem PVC untuk memenuhi setiap kebutuhan terkait sistem perpipaan. Berdasarkan hasil observasi, diketahui bahwa dalam menjalankan proses produksinya memiliki beban kerja yang belum merata. Hal ini didasari dengan adanya operator yang menganggur saat operator lainnya mengerjakan tugas di jam yang sama. Padahal tanggung jawab Extruder Technician I cukup banyak. Ketidakseimbangan ini membuat operator dengan beban kerja yang berlebih akan menerima beberapa dampak buruk seperti lebih mudah lelah sehingga konsentrasi dapat menurun dan cenderung tidak produktif. Analisis ini dilakukan dengan Metode Work Load Analysis (WLA). Metode ini dapat memberikan penjelasan terkait beban kerja yang diterima oleh suatu unit perusahaan sehingga usulan pengoptimalan beban kerja dapat diberikan. Setelah dilakukan analisis, dihasilkan output berupa rekomendasi kebijakan pengoptimalan beban kerja dengan memberikan insentif berdasarkan beban kerja dan tidak melakukan penambahan jumlah tenaga kerja. Hal ini dikarenakan rekomendasi ini memiliki nilai efisiensi yang lebih baik dibandingkan dengan dilakukannya penambahan tenaga kerja, perusahaan hanya perlu mengeluarkan total biaya insentif sebesar Rp. 5.032.575,- untuk tiga orang pekerja dibandingkan harus mengeluarkan biaya Rp. 6.000.000,- untuk satu orang pekerja tambahan.

Bio-algae: a study of an interactive facade for commercial buildings in populated cities

Climate change, global energy demand, and greenhouse emissions from energy (formerly CO2 emissions from fuel combustion) have emerged as the most serious threats to humans, particularly in densely populated cities. As a result, there are calls to reconnect with nature and draw inspiration from its mechanisms as well as to use clean renewable energy resources. Thus, this paper presents a biomimicry approach—a strategy for achieving ecological balance—to biofuel using algae in a building facade, and considers a case study building in Giza city as an example of a populated city in Egypt for retrofitting its skin with a nature-inspired solution. Using mathematical calculation, energy load analysis, and interviews with interested specialists, architects, and building occupants about this technology, then compared the performance of the case study commercial building facade with the proposed algae facade for energy generate. The results indicate that electrical energy consumption can be reduced by 45 to 50%, and carbon emissions could be reduced. In addition, other benefits for the building environment and societal acceptance were revealed. The study concluded that using algae as an element of the building skin in densely populated cities as a biomimicry architecture strategy contributes to an innovative environmental approach.
