Smart Tray: Speculating The Future New Zealand Dining Experience
Authors:   , Levy Joe
Published: November 2021

This research proposes a design solution that embraces New Zealander’s proclivity for pervasive digital technology and that aims to meet the needs and desires of the future Kiwi dining experience. This research proposition is directed by an approach that situates itself between future forecasting and speculative design, whereby the design output is viable while simultaneously capable of provoking critical reflection about the future of design as it relates to domestic dining appliances. The development of a design solution, the Smart Tray, encapsulates these aims and has been guided by a comprehensive investigation into the points of connection that exist between culture, technology, design and social behaviour.  The Smart Tray seeks to acknowledge New Zealand’s history while embodying its contemporary domestic dining culture in proposing an appliance-device that embraces digital technology as part of the everyday dining experience. This research has been supported by the application of various methodologies inclusive of the critical review of academic literature that has functioned to frame and support the scope of the research proposition; case studies in which a selection of Kiwi households have been interviewed, observed, and their behaviours analysed in order to gain a greater understanding of contemporary dining habits and their relationship with pervasive digital technologies at home; and iterative design development inclusive of concept sketching, sketch modelling, experience prototyping, and user feedback. Although this research is contextualised within New Zealand, the general research outcomes are applicable to a wide market. The outputs produced as a result of this research, including the exegesis and design of the final Smart Tray, are intended to offer a valuable critical perspective and viable future design solution that will aid in furthering the professional field of dining design.
Radical Detours: A Situationist Reading of Philip K. Dick
Authors:   , Raba Andrew
Published: November 2021

In this project I read four Philip K. Dick novels against the writing of the Situationist International (SI). In doing so, I seek to disrupt two critical trends that arguably impede Dick criticism: the depoliticization of Dick and the lack of focus on his style. Through reading his work against the politics of the SI, Dick’s own radical politics can be defined and reaffirmed. I make the case that Dick is a writer predominantly concerned with politics and ideology over and above philosophy and ontology. Secondly, I argue that the political power of Dick’s work is inseparable from his avant-garde style; in particular, his frequent use of what the Situationists termed détournement. With revolutionary politics and avant-garde aesthetics in mind, I re-examine the canonical novels Martian Time-Slip and Ubik, and redeem two of Dick’s neglected novels, The Game-Players of Titan and Galactic Pot-Healer.
See you on Wall St. Sept 17. Bring Tent: Occupy Wall Street, Framing, and Mobilisation
Authors:   , Bigwood Samuel
Published: November 2021

The phenomenon of Occupy Wall Street (OWS) has been widely discussed in the academic and popular discourse. Of its many contributions, the language of the Occupy Movement has had a profound influence on contemporary discussions about inequality – contrasting the ‘99%’ with the ‘1%’ is now a permanent part of the conversation. However, despite this discursive shift, the literature has yet to seriously consider how the ideational elements of OWS influenced its mobilisation. While changing the dominant discourse is an important achievement, mobilising collective action around a cause remains an essential task for social movements.  To explain social movement mobilisation, this thesis utilises the framing perspective, which seeks to understand why and how certain ideas are able to inspire or inhibit collective action. By using qualitative analysis of movement texts over time, this thesis has constructed the key frames articulated in selected OWS documents over the course of its serious efforts to mobilise. More specifically, it has examined whether changes in the movement’s use of diagnostic, prognostic, motivational, and identity frames can explain the trajectory of mobilisation. The central argument is that the framing perspective can offer a plausible explanation for the mobilisation of OWS; a correlation between changes in framing and expected changes in mobilisation can be observed. However, while the findings of this thesis fill one important part of the puzzle, in order to corroborate the arguments put forward here future research must consider the way the frames proffered by OWS were actually received and acted (or not acted) upon by potential participants. By doing so, we can not only gain a more perceptive insight into this topical phenomenon, but also improve our understanding of the nature and dynamics of contemporary social movements.
The Molecular Forms of GDF9 In A Range of Mammalian Species
Authors:   , Alhussini Abdulaziz
Published: November 2021

Growth Differentiation Factor (GDF) 9 is a member of the transforming growth factor β (TGFβ) superfamily that is exclusively expressed within and secreted from, the oocyte. This protein has generated much interest as it has been found to play a major role in follicular growth and maturation in mammals, and may be involved in determining litter size. Like most TGFβ family members, it is synthesised as a pre-pro-mature protein and is cleaved at various stages to allow the biologically active mature form to bind its Type II receptor. The aim of this study was to improve our understanding of the different molecular forms of GDF9 that are present within ovarian follicles of a range of mammalian species that differ in litter size. To achieve this aim, Western blotting experiments were performed to illustrate the molecular forms that were present within, and secreted from, the oocytes of rats, pigs, sheep and red deer. The detection of bands that represented the different molecular forms of GDF9 was undertaken using a monoclonal antibody that targeted a conserved region in the mature form of ovine GDF9.  The predominant forms of GDF9 found within and secreted from the oocyte across the species were the promature and cleaved mature forms of GDF9. Densitometry analysis of the Western blots revealed that pig, sheep, and red deer had significantly more of the promature, than the mature, form within the oocyte. Conversely, there were no significant differences between the levels of promature and mature forms of GDF9 in the secreted media. Moreover, the levels of the specific molecular forms of GDF9 were not different between pigs, sheep and red deer. The levels of GDF9 in rat samples were low which may be due to a lower affinity of the monoclonal GDF9 antibody due to sequence differences between rat and ovine GDF9.  Interestingly, applying a crosslinking reagent to the oocyte lysate and conditioned media samples revealed the appearance of a high molecular size band. The appearance of this band, which was more prominent in the rat and pig, was concomitant with the disappearance of the mature GDF9 band. The differential levels of these presumptive GDF9 multimers in these two species that have large litters may suggest that rat and pig mature GDF9 binds other oocyte secreted factors more readily than GDF9 from mono-ovulatory species. Importantly, no homo- or hetero- mature dimers of GDF9 were detected in any of the species studied.  In summary, GDF9 was predominantly present as promature and cleaved mature forms both within the oocyte and in the secretions from the oocyte. Overall, these results indicated that the promature form was present in higher levels than the cleaved mature form. With the exception of the rat, there were no detectable species differences in the levels of the GDF9 forms within or secreted from the oocyte using Western blotting methodologies.
(Re)Presentation in Verbatim Theatre
Authors:   , Smith Tama
Published: November 2021

Using a range of interpretive methodologies and based on both the practice of others and the author’s production, direction and evaluation of a series of shows this thesis explores a number of aspects of verbatim theatre presentation and re-presentation (restaging). The form of verbatim theatre discussed is primarily that deriving from personal interview material and the predominant thesis focus is one of Australasian context and practice.  The thesis is in two separate sectons with strongly related aims; the first section aiming to clarify and support the second. The first section answers questions about verbatim theatre evolution, processes and practices through both reviews of literature and interviews with prominent practitioners. It reveals vitality and diversity in VT practice, breadth and depth of scholarship in both Australia and New Zealand. It illuminates the processes and practices of creating and performing a verbatim play to support those who may consider doing so.  The second section describes and evaluates the performance of re-presentations in August 2015 of the VT play We’ll Meet Again. This play had been developed in 1994 from interviews with war veterans to create a theatrical event honouring a generation whose common experience was involvement in the Second World War. The actors in the re-presentation were all students at Toi Whakaari:New Zealand Drama School and the show was performed in nine venues over six days. Audiences were predominantly elderly although those at community centre venues were of a range of ages.  Tools used to evaluate the performances included audience survey forms with room for written comments, observations of audience responses and verbal feedback and interviews with actors. The remarkably positive survey responses and powerful written and oral testimony support the argument that a re-presentation of verbatim theatre has the potential to reinstate and broaden further the impact, appeal, value and aims of the original work. This argument is further supported with the formation of guidelines to present research findings as well as supporting, in a practical and immediate way, those embarking on re-presentation. A selection of images and performance video, illustrating the context and findings of the research are included in the thesis document.
Address terms in New Zealand English: Tracking changes to the social indexicality of gendered terms of address
Authors:   , Giles-Mitson Amy
Published: November 2021

Recent research has suggested that some conventionally masculine address terms are becoming more gender neutral in English speaking countries. This study examines the four most prominent gendered address forms in New Zealand English: mate, bro, man and guys in order to gain insight into the terms’ social indexicalities, and track any shifts towards gender neutrality. The study takes a mixed-methods approach to analysing two distinct data sets: four corpora of spoken New Zealand English and a data set collected from a range of current media sources. Results from this study suggest that mate is in retreat in younger New Zealanders’ speech, while bro may be increasing in usage as an unmarked form. Results also suggest that both man and guys have a largely gender free status and are being used frequently in New Zealand. These findings contribute to the growing interest sociolinguists are taking in informal address terms by providing an analysis of the interactional and social functions of address forms in New Zealand English.
The lived experience of being a hundred years and over
Authors:   , Naiker-Ratan Ashwina
Published: November 2021

The twentieth century has seen a decline in mortality after the age of eighty and an increase in survival rates of the oldest of the old. Centenarians (people over a hundred years of age) are the fastest growing group of this population in developed countries; however qualitative research on the oldest of the old is limited. The primary aim of this study was to gain an understanding of the essence of lived experiences and meanings of extended longevity as perceived by centenarians. It also aimed to explore the role of lifestyle characteristics, family, social, health and cultural factors in regards to their prolonged existence. The research was conducted with ten centenarians aged between 100 and 106 years living in the Lower North Island namely Wairarapa, Kapiti and Wellington of Aotearoa New Zealand. Biographical Narrative Interpretive Method of inquiry was used to guide the data collection through face-to-face interviews using unstructured open ended questions. Colazzi’s phenomenological framework was employed for data analysis. There were common patterns throughout the life stories related by the centenarians and resilience and acceptance of life was notable. The centenarians spoke nonchalantly about their experience of turning a hundred, describing their birthday as; “Just another day.” Positive personalities and resilient nature were prominent features of the participants who all expressed a sense of acceptance and satisfaction with life and contentment with living in the present. All centenarians had a privileged upbringing and were nurtured during their childhood by their parents, grandparents and siblings and these interrelationships were ongoing at an intergenerational level. They had all kept themselves active as much as they could throughout their lifetime. The results suggest that nurturing has an important role in the survival of the oldest of old.
Anthropocentric: Real-time data for human centric architecture
Authors:   , Voss Timothy
Published: November 2021

This is thesis explores applications of Mixed Reality, commonplace technologies and representation techniques in embodied and interactive design, through the development of an airport wayfinding system. The proposition that airports can be difficult to navigate, struggling to foster social connections, along with the challenging notion of providing an interface for Big Data spatially to users, motivates the research.  The development of personalised spatial way finding techniques aids methods for the use of location and big data to ergonomically and spatially represent users’ navigation of space. Through methods of connecting people virtually within a single physical location using a unified design language, social implications of space are enhanced and extended. Finally, space which functions efficiency provides real-time feedback.  Key theory in Human Computer Interaction and Embodied Design informs the research, through mixed reality, technology and data-form translations.  Research is done over two stages, the first explores data inputs from users and represents these in 2D graphics. The second develops three separate design elements to create a spatial way finding system, to allow user engagement. These are a virtual projection, a set of physical forms and a set of wearable device applications. Design development happens through iterations within each experiment, and are always informed by previous work.  The result is an inhabitable data space with seamless embodied design exploring the localisation of large sets of data.
The Ground Shifting Beneath Us: Collective Memory of New Zealand's Neoliberal Revolution
Authors:   , Neilson Brent
Published: November 2021

This paper explores the collective memory of the neoliberalisation of New Zealand and drastic structural adjustments beginning in 1984 with the election of New Zealand’s Fourth Labour government. Through a cultural sociological analysis of narrative, collected through interviews with both community and voluntary and trade union representatives, use of a cultural sociological understanding of thick description and maximal interpretation reveals how seemingly personal accounts and evaluations take on collective significance. In tracing a path from a collective need for change in New Zealand, to a realisation of the impact of structural adjustment and the collapse of New Zealand’s Labour tradition, this research concludes that the collective memory of this time in New Zealand’s recent history is an ongoing and culturally complex negotiation of collective meaning-making and interpretation. Through an understanding of the collective memory of those who were, and continue to be deeply affected by this period in history, we can begin to understand both the collective impact of neoliberalisation, and the ongoing repair-work needed in New Zealand’s Labour Party, and the Left more broadly.
Coping with emotion in New Zealand Business schools
Authors:   , Scahill Alice
Published: November 2021

Emotion is an integral aspect of organisational life and this thesis examines the emotional demands that academics experience in their workplace and the consequences this has for them. At a more specific level, the thesis examines the strategies that academics use to cope with these emotional demands, and how these strategies develop and change over the duration of their career. Using data collected from interviews with academics from business schools across the New Zealand tertiary education sector, findings are presented which demonstrate how academics develop coping strategies and how the organisation provides support. The implications from these findings could have significant effects for organisational practice. Firstly, these findings illustrate that academics experiences emotion in relation to personal, interpersonal, and systemic factors. Secondly, academics adopt a wide array of coping strategies, which have been personally developed by each individual over time. They are not given any organisational training or support for their development of these strategies. In addition, academics use coping strategies both in the workplace and at home in order to attempt to mitigate the negative impacts of the emotional demands of their roles. Finally, academics in their early career lack adequate coping strategies, and appear to have the lowest levels of organisational commitment.
Testing the Asymmetric Inhibition Model: Frontal EEG Asymmetry Does Not Predict Inhibitory Control of Emotional Distractors
Authors:   , Moody Rosanna
Published: November 2021

Frontal electroencephalographic (EEG) asymmetry is a reliable marker of psychopathology vulnerability, yet the mechanisms underlying this relationship remain unclear. There is accumulating evidence that frontal asymmetry reflects individual differences in ability to use cognitive control to regulate emotional processing. This thesis provides the first test of the asymmetric inhibition model (Grimshaw & Carmel, 2014), which holds that frontal asymmetry reflects ability to engage valence-specific inhibitory control mechanisms supported by dorsolateral prefrontal cortex (dlPFC): left dlPFC inhibits negative distractors and right dlPFC inhibits positive distractors. Frontal asymmetry was tested as a predictor of ability to inhibit distracting emotional images. Frontal asymmetry was measured at rest and during emotional challenge, which is argued to provide a more powerful measure of individual differences (capability model; Coan, Allen, & McKnight, 2006). Emotional challenge was induced using a stressful serial subtraction task, verified to be effective in Study 1, followed by a silent speech preparation task, during which EEG was recorded. An irrelevant distractor paradigm measured ability to inhibit emotional distraction; participants identified a target letter within a central symbol array while attempting to inhibit positive, negative and neutral peripheral images (Study 2). Overall, positive and negative images were more distracting than neutral images. Critically, neither resting nor emotional challenge frontal asymmetry predicted distraction by positive, negative or neutral images, suggesting that frontal asymmetry does not reflect ability to inhibit irrelevant emotional distractors. Thus, the asymmetric inhibition model was not supported. This thesis provides the first direct test of the relationship between frontal EEG asymmetry and inhibitory control of emotion, paving the way for future explorations into this relationship. These findings add to a growing literature attempting to elucidate the cognitive mechanisms underlying frontal asymmetry in order to better understand the etiology of psychopathology.

Analysis on the Education Mechanism of the “Learning Power” Platform from the Perspective of Media Convergence
Authors: Li Zhi
Published: November 2021

As a media learning platform, the “Learning Power” platform integrates the advantages of the internet, big data, and new media. Through the supply of massive explicit and implicit learning resources as well as the construction of the interactive space of “Learning Power,” it fully embodies the education mechanism of moral education. Specifically, it is reflected in the distinctive political position and the education goal mechanism of “moral education,” the education operation mechanism of “explicit and implicit unity,” the learning mechanism of “autonomy and cooperation integration,” and the feedback incentive mechanism of “gamification.” The organic combination and interactive operation of these four mechanisms form a collaborative education mechanism system of goal orientation, education operation, learning process, and feedback incentive.

Published: November 2021

The volume of Indonesia's sugar imports in 2019 reached 4,09 million tons. The high volume of imports was influenced by the decreasing area of sugarcane plantations. Lamongan Regency is one of the sugarcane and sugar-producing regencies in East Java. Sugarcane and sugar production in Lamongan Regency has experienced quite diverse dynamics and has been influenced by changes in land-use conditions. This study aims to analyze the balance of land needs for sugarcane plantations in Lamongan Regency in 2031 based on an analysis of land-use changes using SPOT imagery of 2007, 2013, and 2019. The study was conducted by analyzing land-use changes, population projections, and land demand balance analysis for sugarcane plantations. The results of the analysis showed that the population of Lamongan Regency in 2031 is projected to reach 1.419.843 people with a land requirement for sugarcane plantations of 2.362,29 ha. There will be a land surplus of 1.276,92 ha but it is still concentrated in 7 of the 27 sub-districts. Sugarcane plantations in Lamongan Regency have the potential to be developed considering that the land allocation for plantations in the Lamongan Regency Spatial Plan of 2011-2031 reaches 10.022,42 ha.
Fully Automated Magnetic Resonance Detection and Segmentation of Brain using Convolutional Neural Network
Authors: Shaker Atheel Sabih
Published: November 2021

The brain's magnetic resonance imaging (MRI) is tasked with finding the pixels or voxels that establish where the brain is in a medical image The Convolutional Neural Network (CNN) can process curved baselines that frequently occur in scanned documents. Next, the lines are separated into characters. In the Convolutional Neural Network (CNN) can process curved baselines that frequently occur in scanned documents case of fonts with a fixed MRI width, the gaps are analyzed and split. Otherwise, a limited region above the baseline is analyzed, separated, and classified. The words with the lowest recognition score are split into further characters x until the result improves. If this does not improve the recognition score, contours are merged and classified again to check the change in the recognition score. The features for classification are extracted from small fixed-size patches over neighboring contours and matched against the trained deep learning representations this approach enables Tesseract to easily handle MRI sample results broken into multiple parts, which is impossible if each contour is processed separately Hard to read! Try to split sentences. The CNN inception network seem to be a suitable choice for the evaluation of the synthetic MRI samples with 3000 features, and 12000 samples of images as data augmentation capacities favors data which is similar to the original training set and thus unlikely to contain new information content with an accuracy of 98.68%. The error is only 1.32% with the increasing the number of training samples, but the most significant impact in reducing the error can be made by increasing the number of samples.

Guizotia abyssinica (L.F.) Cass. is one of the important oilseed crops cultivated in India. The seed of the plant is used by the tribal and rural people of our country as a source of edible oil. The present investigation of the Niger plant deals with the study of the back cross-program and improvement in the variety. Unknown local variety (A) of niger was selected as a non-recurrent parent because of having some desirable characters like less vegetative growth (dwarf), resistance to waterlogged condition, and large seed grains while IGP-76 variety (B) was selected as a recurrent parent and used as a female having characters like small black grains, resistant to leaf-eating cater Piller and powdery mildew result shows successfully transfer of the characters in the F1 generation. The average number of capitulum/plant shows very good and positive results in F1 as well as BC1 generation. As compared to the recurrent parent (B) an average number of capitulum per plant was increased in F1 generation by 14.28% and in BC1 generation by 28.5%. The table indicates that there is incensement in the average number of seeds per capitulum. The average number of seeds per capitulum was increased by 8.3% in the F1 generation and by 11.11 % in the BC1 generation as compared to the recurrent parent. Average weights of 1000 seeds were also increased in F1 generation by 31.78% and in BC1 generation by 47.28% along with the total yield per plant.

The SARS COVID-19 pandemic took the whole world by storm due to its high and rapid infectivity. As it spread, its patterns became clear, and it became evident that a few individuals were more predisposed to it than others. Showing a massive inflammatory response by the body, and a negative coagulative affect, doctors and scientists began to perceive the role of blood cells, and hence blood types in the disease process. This lead to the main objective of this research: to assess the link between COVID19 infection and blood group types, and follow disease outcome according to it. The study comprises data collected from patients within 3 hospital setting of Northern Pakistan, viz Military Hospital Rawalpindi, Benazir Bhutto Hospital Rawalpindi, and Pakistan institute of medical sciences Islamabad. The study was conducted during a period of 1 month i-e from 15th June 2020 to 15th July 2020 after approval by the worthy Ethical review committee of PEMH. The study design was Analytical- Case series. Purposive Sampling technique was used. The sample size was 306 based on WHO sample calculator. Patients who were PCR positive and symptomatic for COVID-19 were included whereas PCR negative and asymptomatic patients were excluded. SPSS version 25 was used to process the data and Graphs and Charts were used to explain it. Among 306 patients of COVID 19 the most commonly affected blood group was A+ve followed by B+ve. The least affected blood group was O of which both positive and negative contributed to 17.71%. A blood group contributed 36%, while B 35% and AB 10.8%. The study substantiates that blood group A Rh positive has more susceptibility for SARS COVID-19 infection than other blood group types. Blood group O might have a protective effect against this infection.

INVESTIGATION OF THE CAUSES OF UNSATISFACTORY RESULTS OF ULTRASOUND CONTROL OF EXPERIMENTAL FORGES FROM AUSTENITE HIGH-ALLOY STEEL
Authors: DEINEKO L.M. , SUKHOMLYN H.D. , DERHACH Т. О. , BORYSENKO A.Yu.
Published: November 2021

The purpose of the work is to establish the main causes of defects by ultrasonic testing (UST) of experimental forgings made of high-alloyed austenitic steel 08Kh18N10T on the basis of comprehensive comparative studies of samples of defective and suitable forgings. Techniques. Chemical analysis of forgings was performed on a high-sensitivity spectrometer "SPECTROMAX" company "SPECTRO", Germany; studies of macro- and microstructure (liquation heterogeneity, grain boundary structure, non-metallic inclusions, excess phases, etc.) were carried by the methods: metallographic and electron microscopic with micro-X-ray spectral analysis; tests of forgings for durability against intergranular corrosion (IGC) were carried out by the methods of AMU, GOST 6032. Results. It was established that experimental forgings rejected by UZK, in contrast to suitable forgings, were characterized by: the presence of areas of liquation inhomogeneity of steel, including high content of δ-ferrite; local defects of the macrostructure in the form of flocs; areas with anomalous multi-grained microstructure with a grain size of –2 to 8 points according to GOST 5639; release of chromium carbides at the boundaries of austenitic grains; susceptibility to intergranular corrosion (ICC). All forgings contained non-metallic inclusions within the permissible limits according to GOST 1778, as well as titanium carbides. Scientific novelty. For the first time on the basis of complex researches it is proved that the main reason of unsatisfactory results of UZK of experimental forgings from high-alloyed austenitic steel, is the anomalous multigrain structure connected with the unstable temperature-deformation mode of forging of ingots. Practical significance. Recommendations for improving the structure and improving the quality characteristics of industrial forgings made of high-alloy austenitic steels in terms of industrial production have been developed.

Forecast of mechanical properties of metal products
Authors: Ivantsov S.V. , Tiutieriev I.A. , Slupska Yu.S. , Sinchuk R.R.
Published: November 2021

Introduction. The mechanical properties of the metal depend primarily on their chemical composition and structure. The structure of metal materials is formed under the influence of different temperature modes of manufacture and cooling. Models for predicting the mechanical properties of steels and cast irons are based on the influence of chemical composition and structure. The paper considers an approach that allows to evaluate the mechanical properties of rolling (C) cast iron rolls with a pearlitic (P) matrix depending on the complex influence of the elements of their chemical composition. Materials and methods. The working area of СПХН roll cast iron samples from the surface up to 50 mm doped with chromium (X) and nickel (H) was investigated. The carbide content varied from 10 to 15 %; and lamellar graphite did not exceed 2 %. The results of the experiment. In the work for modeling the mechanical characteristics of cast iron rolls used the method of planning experiments. The choice of this technique is due to the multi-parameter technology of production of solid metal casting. The application of this technique allowed to obtain models for predicting the mechanical characteristics of roll cast iron SPHN depending on the influence of the elements of the chemical composition of the rolls (C, Si, Mn, P, S, Cr, Ni). The error in predicting the tensile strength sВ, bending strength sзгин bending and hardness according to the Shore HSD method did not exceed 5,89 %. When checking the models for convergence of results by Fisher's criterion at a critical value of Fcrit = 2,400 for sВ, this coefficient was 1,249; for sзгин fold was 1,289 and for HSD - 1,012. To analyze the effect of carbon on mechanical characteristics, two-dimensional dependence plots are constructed. Conclusions. Within the operating values of the parameters of the chemical composition of cast iron rolling mills СПХН-45 in accordance with existing regulations, a forecast of their mechanical characteristics within the allowable limits of error of experimental data. The results of the work allow to obtain mathematical models in the process of production of rolls of the СПХН brand to quickly establish their chemical composition within the standard technology in accordance with the customer's requirements for these mechanical characteristics. In addition, the obtained models can predict these characteristics of the manufactured rolls with minimal material and time costs.

Problem statement. Most modern materials have a polycrystalline structure. Their most important property − mechanical strength − is determined by the defective structure of the crystals. Under the defective structure should be understood not only the concentration and distribution of point defects, dislocations, packaging defects, but also the grain boundaries. The development of such processes as diffusion, recrystallization, plasticity, creep, fragility, cracking and corrosion resistance depends on the grain boundaries. The degree of this influence is directly related to the peculiarities of the atomic structure of boundaries and their interaction with other defects. Therefore, the study of the influence of interfacial and intraphase boundaries on the development of plastic deformation in modern materials is an urgent task. Purpose of the article. Investigation of the influence of the type of polycrystalline boundaries on the kinetics of propagation of plastic deformation in low-carbon low-alloy steel 06Х1. Conclusion. Investigation of the influence of the type of polycrystalline boundaries on the kinetics of propagation of plastic deformation in low-carbon low-alloy steel 06Х1. Conclusion. For low-carbon low-alloy steel 06Х1 the influence of the type of polycrystalline boundaries on the kinetics of plastic deformation propagation is investigated. The relationship between the propagation of plastic deformation and the type of interfacial and intraphase boundaries is established. The proposed physical model takes into account the ability of structural components to block plastic deformation.

SMK XYZ is a Vocational School based on technology and located in South Jakarta. This school has several majors, namely Software Engineering (RPL), Network Computer Engineering (TKJ) and Multimedia (MM). Every new school year, new students of new students who register increases. However, there are problems encountered in the process of selecting student majors, namely inaccurate decision making, there is no ranking, decision making has not used the method and is still using Microsoft Excel, so it requires quite a long time in determining student majors. The purpose of this study is to create a decision support system that is expected to help in determining the right majors for new students in SMK XYZ in accordance with the criteria set by SMK XYZ. This research resulted in a decision support system using the Profile Matching Method as a method for determining alternative final values. Reports produced by this system are value reports that contain the values calculated by students' grades. This decision support system was created using MySQL as a database and Microsoft Visual Studio 2008 as a system creation tool. With this support system, it can help the student in processing data and decision making in order to determine student majors.

All dishes originating from West Sumatra are more popularly known as Padang cuisine. Padang cuisine is one of the most preferred dishes by Indonesians and foreign tourists. Restaurants that serve Padang cuisine, spread all over Indonesia. One of them is the Takana Juo Restaurant located in Singkawang, West Kalimantan. This restaurant serves a variety of side dishes with a distinctive taste from West Sumatra. The problem that occurs in this restaurant is that this restaurant often runs out of several types of side dishes, while there are still many other side dishes, so that many side dishes are often left out every day. So, a solution is needed to see the buying patterns of customers from restaurants in buying side dishes, so that the restaurant can arrange the side dishes that will be sold every day. The data mining approach is considered suitable for finding these customer buying patterns. This study uses data on side dishes sales in one day as a sample data of 12 transactions. Examples of the resulting buying patterns are 12 transactions that buy grilled chicken, 6 transactions buy beef rendang. The algorithm used to help restaurants find customer buying patterns is the FP-Growth Algorithm, so it can help restaurants regulate the number of side dishes to be sold each day. The result of this research is the decision in the procurement of side dishes at the restaurant which can be seen from the frequency pattern of side dishes purchases made by customers.

The human face can be used to assess because of its uniqueness based on certain parameters. To perform facial recognition, the first thing that needs to be done is face detection. The author uses the Viola-Jones method to detect faces. The Viola-Jones method is known to have high speed and accuracy because it combines several concepts (Haar Features, Integral Image, AdaBoost, and Cascade Classifier) into the main method for handling objects. The principle of camera face recognition itself is that the captured face object will be processed and compared with all face images in the existing data set so that the identity of the face is known. One of the applications of face recognition is to do attendance with individual faces. The attendance process does not need physical contact interactions between humans and devices such as the fingerprint system so that during the current COVID-19 pandemic, the spread of the virus can reduce. In this research, a system that can be checked and a person's face is used as a leverage medium for arrival and return attendance using the Viola-Jones method and the LBPH algorithm. The language used is python with the OpenCV library. The PHP language is used for the user interface so that users perform attendance via a browser with the MySQL database to store attendance data. The result of the research is that using the Viola-Jones method and the LBPH algorithm faces are identified and the data is stored in the database used for data attendance. Distance and slope affect the results of face recognition. The distance is too close about 30 cm from the camera, the face cannot be detected. Instead of face position is too far approximately 200 cm, the face can still be detected but could not be identified. For a face tilt level of about 20o from perpendicular, it can still be recognized, but at a tilt degree of about 30o up or to the right, faces cannot be detected.

Accuracy in calculating exposure in photographic techniques is the key to being able to produce good quality photos. The light calculation includes three elements (Triangel Exposure), namely shutter speed (shutter speed / t), ISO sensitivity, and diaphragm (aperture / f). A light meter is a tool for calculating lighting in the world of photography to accurately calculate the light falling in or around the object to be photographed. The light meter has a working principle like a lux meter calculates the value of light intensity in a place. However, on a light meter for photography, there is a calculation of a triangle exposure in it. This light meter prototype uses an ATMega328 microcontroller on the Arduino Nano V3 with the help of a TSL2561 light sensor and a TCS34725 RGB color sensor. Tests were carried out by comparing the output value using an original light meter, namely Sekonik Flashmate L-308X with the continuous light shooting method. The results of the test using the original tool with the ATMega328 microcontroller produced values above 90%.

New Student Admission (PSB) is an annual program held by the school to get students, according to the criteria desired by the school. One of alternatif method to determine the ranking of prospective new students is to use the SAW (Simple Additive Weighting) method. To reduce the subjectivity that arises in the use of the SAW method, a correlation analysis technique is used which is useful for knowing the level of correlation of each criterion on new student admissions. Based on the results of the research, it was found that the parents' income criteria had the highest weight (0.851), followed by math scores (0.845), English scores (0.831), physics scores (0.577), physical ability (0.539), and finally student interest (0.282). Meanwhile, the results based on ranking using the SAW method showed that students A3 (Alternatif 3) had the largest V1 value compared to other alternatifs, which was 3.54. So it can be concluded that A3 are students with the best final scores compared to other students.
