Effect of carburizing time on mechanical properties of fe-24mn steel / Muhammad Aqeel Rusdi
Full text linkHigh Manganese steels is a type of steel that have highly desirable properties exhibiting both high strength and good ductility especially in a sheet form. This steel is widely used in industrial - M process, it was observed that the mechanical properties and microstructure of Fe-24Mn steels were found to be influenced by pack carburizing process. Carburizing for longer times (1 to 3 hours) provided improvement on mechanical properties of Fe-24Mn steel such as ductility, ultimate tensile strength and micro-hardness of the specimen even though the ultimate tensile strength value is still lower than uncarburized Fe-24Mn steel. The study also proves the carburizing process on Fe- M α-austenite (at surface) an ε-martensite (at core). Finally, the specimen that has been carburized for 3 hours produced best result in overall
Gas leakage notification and monitoring system (notification using GSM) / Muhammad Aqeel Mohd Nazaran
Full text linkNotification about gas leak is important in preventing the unexpected scenario that can cause a lot of people life caused by gas leakage. Gas leakage is the main factor of starting of fire and explosion happens nowadays. On 2011, an explosion of gas pipeline happens in the Emperor shopping mall at Subang, Malaysia that is caused by the gas leak due to the flawless welds of the pipeline. In preventing this situation happens, the gas detector with notification by sending SMS using GSM modem needed in aware the people if danger is coming. This project is focuses on the sending SMS notification to the technician about the gas leak occur. The GSM modem is used in this notification system to sending the SMS to the technician if there any gas leak presence
Contrast enhancement technique to improve visualisation of wooden and graphite foreign bodies in soft tissue computed radiography / Muhammad Aqeel Muhamad Tari
Full text linkPurpose: This paper evaluates the ability of contrast limited adaptive histogram equalization (CLAHE) using Image J software to improve the visibility of wooden and graphite foreign bodies in soft tissue. Methods: The wooden and graphite were selected as foreign bodies with different dimension. Wooden and graphite foreign body were embedded in jelly which has density equivalent to the soft tissue. The jellies have different thickness to simulate density of different extremities. The wooden and graphite were selected due to wide availability, frequency and appropriate size for accidental intrusion of foreign body. Computed radiography images of embedded foreign body were obtained. Ten radiographer blinded to number of object were ask to count number of wooden and graphite foreign body visible in CLAHE images and general post processing images. This study going to test limited adaptive histogram equalization (CLAHE) ability by comparing number of foreign body visualize in CLAHE images to general post processing image. Result: The test result show visualization of wooden and graphite foreign body using contrast enhancement technique (CLAHE) has significant different compared to general post processing technique in computed radiography (p < 0.05). Conclusion: This study showed the contrast limited adaptive histogram equalization (CLAHE) technique using ImageJ was better on the visualisation of wooden and graphite in the soft tissue compared to the general post processing technique
Feedback dynamic control for exiting a debt-induced spiral in a deterministic Keen model.
No full textThe Keen model is designed to represent an economy as a dynamic system governed by the interactions between private debt, wage share, and employment rate. When certain conditions are met, the model can lead to a debt spiral, which accurately mimics the impact of a financial crisis on an economy. This manuscript presents a recipe for breaking this spiral by expressing Keen's model as an affine nonlinear system that can be modified through policy interventions. We begin by considering critical initial conditions that resemble a financial crisis to achieve this goal. We then locate a desired point within the system's vector field that leads to a desirable equilibrium and design a path towards it. This path is later followed using one-step-ahead optimal control. We illustrate our approach by presenting simulated control scenarios
Parent(-ing) at work: how employees navigate parenthood at work
No full textRecent studies indicate that both work and nonwork experiences influence each other, leading to a highly interconnected and blended work-life experience for employees. This insight challenges the traditional assumption that the institutionalized nature of work and home confines roles to specific times and spaces. However, this insight has yet to be sufficiently incorporated into management scholarship, hindering our ability to fully understand how work-nonwork roles overlap and are managed. The parent role constitutes a dominant nonwork role that impacts work in a range of ways. Scholars disproportionately focus on the incompatibility between parent and work roles without addressing the outcomes of this incompatibility for employees’ lives or how it is managed. Our symposium presents five papers that exhibit the consequences of combining parenthood and work for the lives of employees as well as its navigation in both work and nonwork domains. Contributors draw on diverse theoretical perspectives¬—relational exchange, infrastructure shock, gender schema, role theory, boundary work, and identity—and unique contexts—entrepreneurship, a religious community, COVID-19, and fishermen community—to provide a broad vision of the parenthood-work overlap dynamic and its navigation. To foster meaningful discussions between the authors and the audience, our symposium will use a round table format instead of featuring a discussant after the paper presentations.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
