    Laboratorium komputer merupakan fasilitas yang sangat penting sebagai penunjang pembelajaran berpraktikum. Setiap program studi pada Institut Informatika dan Bisnis Darmajaya pasti menggunakan Laboratorium komputer dalam rangka pembelajaran unggul berbasis riset dan teknologi informasi. Namun seiring waktu, perangkat komputer pasti ada yang mengalami kendala atau kerusakan, seperti keyboard tidak berfungsi, kabel lan yang tidak terkoneksi, sistem operasi corrupt bahkan komputer tidak menyala yang mana hal ini akan menghambat proses pembelajaran berpraktikum. Proses perbaikan harus dilakukan dengan cepat agar pembelajaran berpraktikum tidak terhambat. Pada proses manual kegiatan monitoring dan pengecekan Laboratorium Institut Informatika dan Bisnis Darmajaya dilakukan setiap hari meliputi pengecekan software, hardware dan juga jaringan komputer. Proses pengecekan dilakukan satu persatu oleh laboran dengan membawa formulir manual pada setiap pengecekan Laboratorium. Komputer yang bermasalah atau berstatus rusak dilakukan pencatatan menggunakan form dan kemudian dilaporkan kepada koordinator laboratorium. Data kerusakan tersebut selanjutnya dilakukan rekapitulasi untuk dilakukan evaluasi, proses ini cukup memerlukan waktu karena proses rekapitulasi tidak dapat dilakukan secara langsung (realtime). Adapun kendala yang terjadi yaitu proses yang kurang efektif dalam penanganan kerusakan laboratorium komputer.

    Although the inheritance of genetic information has long been established, it is now apparent that epigenetic information can also be transmitted through the generations. This phenomenon is referred to as transgenerational epigenetic inheritance (TEI) and refers to the inheritance of gene regulatory information without altering the DNA code itself. TEI has been observed in a range of model species, including Mus musculus, Drosophila melanogaster, and Caenorhabditis elegans and has implications for viral defence, germline mortality, and natural selection, with the possibility of adding to the complexity of phenotypic traits outside of only genomic variation. The work presented in this thesis utilizes C. elegans as a model and primarily focusses on the highly homologous predicted histone methyltransferases set-9 and set-26 and their paralog Y73B3A.1, examining their phylogenetic history and their role in TEI and germline mortality. Comparisons with other Caenorhabditis species revealed that set-26 is the ancestral gene that gave rise to set-9 and Y73B3A.1 in the C. elegans lineage. The predicted protein domains encoded in these genes display functions in TEI and germline mortality, confirming that their predicted inactive SET domains do indeed have biological function. This thesis also examines a range of other factors previously implicated in TEI, further elucidating their generational requirements. Understanding both TEI and germline mortality in C. elegans provides a framework to better study these processes in other species

    A User Study for Evaluation of Formal Verification Results and their Explanation at Bosch

    Context: Ensuring safety for any sophisticated system is getting more complex due to the rising number of features and functionalities. This calls for formal methods to entrust confidence in such systems. Nevertheless, using formal methods in industry is demanding because of their lack of usability and the difficulty of understanding verification results. Objective: We evaluate the acceptance of formal methods by Bosch automotive engineers, particularly whether the difficulty of understanding verification results can be reduced. Method: We perform two different exploratory studies. First, we conduct a user survey to explore challenges in identifying inconsistent specifications and using formal methods by Bosch automotive engineers. Second, we perform a one-group pretest-posttest experiment to collect impressions from Bosch engineers familiar with formal methods to evaluate whether understanding verification results is simplified by our counterexample explanation approach. Results: The results from the user survey indicate that identifying refinement inconsistencies, understanding formal notations, and interpreting verification results are challenging. Nevertheless, engineers are still interested in using formal methods in real-world development processes because it could reduce the manual effort for verification. Additionally, they also believe formal methods could make the system safer. Furthermore, the one-group pretest-posttest experiment results indicate that engineers are more comfortable understanding the counterexample explanation than the raw model checker output. Limitations: The main limitation of this study is the generalizability beyond the target group of Bosch automotive engineers.Comment: This manuscript is under review with the Empirical Software Engineering journa

    ‘Making Floppy Floppy': Peter Halley's Postmodernist Abstraction (1980-1987):

    Get PDF
    Having completed studies at Yale and The University of New Orleans, in 1980 American artist Peter Halley returned to his hometown in New York City, took a studio in the East Village, and began to paint. Within six years he would become one of the most talked about artists in America. In this thesis I argue that Halley’s paintings of the 1980s constructed new relationships, or chains of meaning, between past abstract art—in particular, though not exclusively, forms of American minimalist abstract painting and sculpture from the 1950s and 1960s—and a range of social forms and urban textures particular to New York City. By suggesting new social interpretations of past abstract art, Halley’s model of ‘postmodernist abstraction’ prompts us to revise our understanding of the historicity and criticality of postmodernist painting. Pushing back against arguments about 1980s postmodernism as historical amnesia (Fredric Jameson), or market-complicit conventionalism (Hal Foster), I read Halley’s ‘Neo-geo’ as one example of how strategies such as pastiche and double-coding—identified by many critics as central tenets of the postmodernist art that emerged in New York in the 1980s—functioned as vehicles for historical orientation during a decade otherwise marked by disorientating economic, social, and cultural change

    ArchĂ€ologische und naturhistorische Museen bedienen sich heutzutage eines breiten Spektrums medialer Vermittlungsformen zur Bereicherung und UnterstĂŒtzung der Visitor Experience. Im Bereich digitaler Medien nehmen hier mobile Vermittlungsmedien in Form von Apps für Smartphones und Tablets seit mehr als einem Jahrzehnt eine vergleichsweise neue, vor allem aber exponierte Position ein, indem sie besuchereigene EndgerĂ€te als Vermittlungsmedien nutzen und lediglich die Inhalte museumsseitig bereitgestellt werden. Das Angebot einer App bietet damit die Möglichkeit eines ortsunabhĂ€ngigeren, interaktiveren und partizipativeren Zugriffs auf eine Ausstellung und ihre Objekte sowie die Möglichkeit, den Museumsbesuch ĂŒber die gesamte Visitor Journey zu personalisieren. Die vorliegende Dissertation setzt hier an und untersucht die Nutzung und Wirkung einer Museums-App im Sinne einer digitalen Besucherforschung anhand eines interdisziplinĂ€ren Ansatzes beispielhaft und umfassend im museographischen Kontext des Neanderthal Museums. Mit der medieninformatischen Entwicklung einer Forschungs-App wird sowohl ein quantitativer als auch durch die Einbeziehung von Besucherinterviews, ein qualitativer Ansatz einer multiperspektivischen Analyse verfolgt. Vor diesem Hintergrund wird das Potential von Apps im museographischen Kontext archĂ€ologisch-naturhistorischer Ausstellungen nicht nur am Beispiel des verwendeten Settings, sondern auch in Bezug auf thematisch Ă€hnliche Museen diskutiert

    Simplifying Sensor Systems: The Rugged, Accessible, and Printed Future of Electroanalytical Monitoring

    Low-cost sensor arrays are required to allow for real-time, in-situ electrochemical monitoring using Internet-of-Things (IoT) systems; however, they are currently not practical due to a lack of stable, mass-producible reference electrodes. To solve this problem, in this thesis a screen-printed Ag/AgCl true reference electrode with an offset salt reservoir on a flexible substrate was developed for use in disposable, low-cost sensors. The solid-state electrolyte containing KCl and poly(vinyl acetate) was developed, and deposition of a PDMS junction membrane suppressed electrolyte leaching. The optimum electrode construction was assessed based on the performance of electrodes with varied structures, and potential stability of −45.5 ± 3 mV vs. SCE with low drift was maintained for up to 27 days for electrodes containing both the electrolyte and PDMS layers, compared to less than 1 day without the PDMS junction. The electrodes were stable in solutions at different pH and were also insensitive to most interfering ionic species under continuous potential measurement. Further electrochemical and physical characterisation studies of the failure mechanisms for the developed reference electrode showed the limiting factor for their lifetime to be the size of the internal salt reservoir, and that the addition of the PDMS junction greatly increased the utility of the reservoir layer. To create a printed sensor array, a screen-printed Au electrode was developed and combined with the studied reference electrode. The suitability of the system for different potentiometric and voltammetric use-cases was assessed, including ORP evaluation and heavy metal sensing. The system, as well as the individual developed electrodes, was then compared to commercially available screen-printed systems and was found to be equally or more suitable than the existing units for the examined use-cases. In summary, the results demonstrate that the developed reference electrode performed strongly in OCP lifetime and interference measurements, and for use in ORP, pH, CV, and heavy metal potentiometric and voltammetric sensing, when combined with commercial electrodes or the created Au electrode, due to addition of the PDMS junction. The low-cost screen-printed Au and novel reference electrodes are therefore well suited for use in electroanalytical systems for high volume IoT applications

    Young farmers' and ranchers' perceptions of mental health

    Mental health is a concerning issue for all, especially farmers and ranchers who are dealing with mental health disorders. However, limited research has been conducted related to mental health in the agricultural field, specifically looking at the perceptions of mental health among young farmers and ranchers. The purpose of this study was to determine mental health perceptions of young farmers and ranchers and to inform strategies to help break the stigma surrounding mental health in agriculture. Almost all literature agrees that farming and ranching are stressful occupations and have very high rates of mental health illness among their producers. This is because of well-documented occupational stressors like finances, time pressures, economic conditions, and hazardous working conditions coupled with demographic effects like isolation from a community and access to mental health care. Mental health for farmers and ranchers has been identified as a growing concern for the research community and is a new topic with a need for continued research and development of preventive measures. This study’s theoretical framework followed Bronfenbrenner’s ecological theory. The instrument was developed by the researchers with input from industry professionals and was a combination of Semantic Differential questions and 5-point Likert-type scale questions, paired with demographic based questions to achieve the research objectives. Results from this study can only be generalized to the 36 participants. Due to the lack of responses to the questionnaire, this study should be repeated to determine if participant demographics and attitude responses change with more responses. Overall, participants responded with relative cohesiveness. It’s agreed that mental health is an issue farmers and ranchers face, and something should be done to eliminate the stigma surrounding the topic. Young farmers and ranchers believe they have access to mental health resources and believe they are prepared to and confident in assisting others with mental health challenges

    Consequences of Environmental Manipulation on Behavioural and Neuromorphological Plasticity as It Relates to the Reintroduction of Atlantic Salmon (Salmo salar) to Lake Ontario

    The reintroduction of imperilled species has become an important tool in conservation biology and relies on the captive-rearing of remaining individuals, or a subset thereof, as a lifeline to prevent extinction. The success of reintroduction efforts has generally been low, mainly due to poor post-release performance of captive-reared animals. Captive-breeding programs tend to produce behaviourally and neurologically compromised animals that deviate from wild phenotypes and are less fit in natural settings. While genetic adaptation can account for some of the behavioural deficiencies expressed by captive-reared animals, phenotypic plasticity has been shown to play a large role. Phenotypic plasticity is generally defined as the ability of an individual to produce different phenotypes, or change the trajectory of phenotypic development, when exposed to different environmental conditions. This thesis proposes that by understanding the environmental factors and mechanisms that shape the phenotype, conservation biologists and managers alike can alter the rearing conditions and release protocols of captive-bred animals destined for stocking to increase the success of reintroduction efforts. Throughout this thesis I examine the effects conditioning tactics – methods aimed at manipulating the rearing environment and release protocol to counteract the negative effects of captive-rearing on fitness-related behaviours in Atlantic Salmon (Salmo salar). Specifically, I investigated the effects of manipulating the early developmental rearing via enrichment (sensory enrichment via alarm cue exposure and physical enrichment via increased structure in the rearing environment) on anti-predator related behaviours. Alarm cue exposure during early development had no significant effect on anti-predator related behaviour but fish exposed to alarm cue showed significant plastic changes to regional brain volumes (smaller olfactory bulbs), suggesting the potential for alarm cue to affect post-release behaviour. Physical enrichment during early development resulted in more wild-like behavioural phenotypes but did not ameliorate behavioural effects associated with stressful transport. I also investigated the effect of soft-release tactic – providing an in-stream acclimatization period prior to release– on the movement behaviour of fish released to the wild. Soft-released fish significantly differed from conventionally released (hard-release) fish in movement patterns, more closely matching wild-like movement pattern for this species. Finally, I investigated the effects of embryonic exposure to an artificial odorant (morpholine) and tested for behavioural evidence of imprinting at later developmental stages using two separate analytical approaches. Fish exposed to morpholine during the embryonic stage showed evidence for imprinting (a phenotypic plastic response) at the smolt stage but not the parr stage. This suggests that imprinting can be detected at a stage relevant for reintroduction efforts and provided support for the use of time-sensitive analyses when testing for behavioural evidence of imprinting. This thesis provides supports for the use of conditioning tactics to manipulate phenotypically plastic responses to aid in the successful establishment of reintroduced animals to the wild. It also provides insight into the mechanisms involved in phenotypically plastic responses to changing environments

    Perspective, Invention, and Metatheater in Renaissance Literature

    Get PDF
    This dissertation challenges the misconception of post-Reformation England as iconophobic. On the contrary, it argues that early modern English poets and playwrights adapt Continental theories and techniques from painting, translating them into their own poetic and dramatic forms. It explores how allusions to contemporary perspectival images serve as governing metaphors and structural devices for the works in which they appear. Particularly in the genre of the Elizabethan epyllion and in works by Shakespeare, it suggests that texts are designed to be read “perspectively,” to borrow Shakespeare’s coinage, so that they are open to ambiguity and multiplicity, and capable of being interpreted in conflicting or complementary ways. In chapters on the Elizabethan epyllion, it examines how the rhetorical superfluity and linguistic play of Marlowe’s Hero and Leander and the satirical experience of “curious viewing” in Marston’s Metamorphosis of Pigmalion’s Image effect a shift in the period’s understanding of artistic invention. In chapters on Shakespeare, it reveals how the modern interest in Shakespearean metatheater — where the theater draws attention to itself as theater — is in fact grounded in the contemporary language of visual perspective. It shows how Shakespeare cues his original audiences to view his plays as perspectival double images, constituted not only by the embodied characters within the fictional worlds of his plays, but also as the physical, human actors of his professional playing company in early modern London. It contends that Shakespeare’s plays become increasingly visual and perspectival, changing meaning and resonance depending on venue, after his professional playing company, the King’s Men, acquire their second playhouse, the Blackfriars. This dissertation therefore traces evolutions in aesthetics and dramatic form occasioned by contemporary developments in the period’s larger visual culture, breaking new ground on the confluences between the visual, poetic, and dramatic arts

    Feasibility study for developing an event prioritizing system using CMSs

    Get PDF
    A content management system (CMS) is software that lets users make, modify, publish, and save digital information. These systems provide a piece of software called a plugin, model, or extension that plugs into users' sites and add new functionality or extends existing functionality on the user site. In current events, prioritization is done manually. When changes in event attributes like personnel, logistics, or money happen after the hand-prioritized list of activities is completed, it is not an easy task to reprioritize. By developing an event prioritization plugin, the organizations in need will use it and reduce time and money consumption. This study aims to recognize and evaluate the existing CMSs, their domains, and available plugins. Assess the availability of event prioritization plugins and recommend developing a plugin to help charity organizations to select the best team and resources and conduct the events effectively. The search is done in the area of the developed research questions. Search phrases containing pertinent keywords were used to find primary studies linked to CMSs categorized under journal articles, conference papers, seminars, symposiums, book chapters, and related CMSs websites
