The other side of monitor engineering : exploring the human component of monitor engineering through occupational stress

Tampereen ammattikorkeakoulu Tampere University of Applied Sciences Degree Programme in Media Music Production Kimberly Grice: THE OTHER SIDE OF MONITOR ENGINEERING: Exploring the human component of Monitor Engineering through Occupational Stress Bachelor's thesis 59 pages, appendices 54 pages April 2018 Monitor engineering is a profession that is generally regarded as highly technical in nature. Yet at the core of this vocation is a line of collaboration between the artist and the engineer that is profoundly based on intimate human interaction that is rarely acknowledged. The goal of this thesis was to examine the human side of “Monitor Engineering” by delving into the occupational stress that a sound engineer, particularly a monitor engineer might encounter and must ultimately overcome if they are to be successful in the field. This thesis does not focus on the subject from the perspective of a particular country or said culture though certain aspects of research study material was drawn from specific countries. Instead this thesis looks at the entertainment field, as a unique sub-culture within any given culture. As it is often the case that a monitor engineer will work in concert with specific individuals, e.g., performers, lighting technicians, pyro technicians, or other sound technicians within the world of live event from various cultures. A brief theoretical view of stagehands as related to live performance is given, followed by a brief description of the different audio professions in the live event industry. As it is important to understand the differences in the vocations that exist within the technician’s world of “live performance”, after which numerous stress factors were investigated using research studies, tomes, and expert interviews. This thesis explored the following questions by way of looking at the work-related stress that exists within the live event field: 1. Is monitor engineering more people oriented than technical? 2. Should conflict resolution, psychoacoustics, and psychological training be a part of the curriculum for those going into field of monitor engineer? 3. Do monitor engineers contribute to the occupational stress experienced by performers and themselves when they are unable to perceive and contend with the mental and emotional states around them? 4. Can having conflict resolution, psychoacoustics and psychological training help monitor engineers perform their jobs and deal with occupational stress on a personal level? This thesis is not a psychological analysis. Instead this thesis will endeavor to illuminate the elements of stress that are experienced in the entertainment industry by a monitor engineer for future students who are interested in the vocation.
A new high-resolution nationwide aboveground carbon map for Brazil

Brazil is home to the largest tracts of tropical vegetation in the world, harbouring high levels of biodiversity and carbon. Several biomass maps have been produced for Brazil, using different approaches and methods, and for different purposes. These maps have been used to estimate historic, recent, and future carbon emissions from land use change (LUC). It can be difficult to determine which map to use for what purpose. The implications of using an unsuitable map can be significant, since the maps have large differences, both in terms of total carbon storage and its spatial distribution. This paper presents comparisons of Brazil’s new ‘official’ carbon map; that is, the map used in the third national communication to the UNFCCC in 2016, with the former official map, and four carbon maps from the scientific literature. General strengths and weaknesses of the different maps are identified, including their suitability for different types of studies. No carbon map was found suitable for studies concerned with existing land use/cover (LULC) and LUC outside of existing forests, partly because they do not represent the current LULC sufficiently well, and partly because they generally overestimate carbon values for agricultural land. A new map of aboveground carbon is presented, which was created based on data from existing maps and an up- to-date LULC map. This new map reflects current LULC, has high accuracy and resolution (50 m), and a national coverage. It can be a useful alternative for scientific studies and policy initiatives concerned with existing LULC and LUC outside of existing forests, especially at local scales when high resolution is necessary, and/or outside the Amazon biome. We identify five ongoing climate policy initiatives in Brazil that can benefit from using this map.
IMPACT OF SENTIMENTS ABOUT THE COVID-19 VACCINE ON THE BRAZILIAN FINANCIAL MARKET

This paper had two main objectives: the first was to perform a sentiment analysis to detect the dominant feeling of twitter brazilian users about the vaccine/vaccination against Covid-19 in that country, and the second one was to investigate if there is a relationship of dependence between the verified feeling and the oscillations of the intern stock market. To carry out the research, machine learning algorithms were used. For sentiment analysis the method used was Naive Bayes, and to execute the forecast of the financial market, it was used SVM method combined with the cross-validation technique applied to time series. As a result, it was found that the dominant feeling about the analyzed topic was negative for all days that comprised the research sample and the highlight of the negative messages was the reaffirmation of the pandemic situation and the allusion to terms related to politics. Furthermore, the research was not able to confirm the dependence relationship between the daily sentiment about the Covid-19 vaccine and the oscillations observed in the financial market. Finally, the found results suggest a more incisive action by political entities in vaccination and information campaigns, to regain public credibility with regard to the control of the pandemic in the country. Despite that, it suggests the application of other methods to investigate the relationship between sentiment and the financial market, for example, to analyze this relation in hours and minutes, instead of days.
Aging models and parameters of quartz crystal resonators and oscillators

For practical applications of quartz crystal resonators, accurate estimation of the aging pattern and adoption of appropriate correction procedure will be important in ensuring the precise operating condition and maintaining their optimal performance. There are two generally accepted aging models for the prediction of long-term behavior of quartz crystal resonators. The Arrhenius model is universally accepted for aging of most materials in engineering applications under a physical process, while the Mattuschka model is an empirical formula from quartz crystal device industry based on the long-term measurement of quartz crystal resonators. In this study, quartz crystal samples from major producers in different countries are collected and a common testing standard was adopted. From the statistical analysis of measurement data, it is found that the Arrhenius model has a much better agreement. Different products and measurements are consistent with the general trend of aging patterns from the Arrhenius model but the key parameters are different from products.
On Dual-Rail Control Logic for Enhanced Circuit Robustness

Ultra low-power design and energy harvesting applications require digital systems to operate under extremely low voltages approaching the point of balance between dynamic and static power consumption which is attained in the sub-threshold operation mode. Delay variations are extremely large in this mode, which calls for the use of asynchronous circuits that are speed-independent or quasi-delay-insensitive. However, even these classes of asynchronous logic become vulnerable because certain timing assumptions commonly accepted under normal operating conditions are no longer valid. In particular, the delay of inverters, often used as the so-called input 'bubbles', can no longer be neglected and they have to be either removed or properly acknowledged to ensure speed-independence. This paper presents an automated approach to synthesis of robust controllers for sub-threshold digital systems based on dual-rail implementation of control logic which eliminates inverters completely. This and other important properties are analysed and compared to the standard single-rail solutions. Dual-rail controllers are shown not to have significant overheads in terms of area and power consumption and are even faster in some cases due to the elimination of inverters from critical paths. The presented automated synthesis techniques are very efficient and can be applied to very large controllers as demonstrated in benchmarks.
Resource Allocation in Multi-Radio Multi-Channel Multi-Hop Wireless Networks

A joint congestion control, channel allocation and scheduling algorithm for multi-channel multi-interface multi- hop wireless networks is discussed. The goal of maximizing a utility function of the injected traffic, while guaranteeing queue stability, is defined as an optimization problem where the input traffic intensity, channel loads, interface to channel binding and transmission schedules are jointly optimized by a dynamic algorithm. Due to the inherent NP-Hardness of the scheduling problem, a simple centralized heuristic is used to define a lower bound for the performance of the whole optimization algorithm. The behavior of the algorithm for different numbers of channels, interfaces and traffic flows is shown through simulations.
A Coding Method for Efficient Subgraph Querying on Vertex- and Edge-Labeled Graphs

Labeled graphs are widely used to model complex data in many domains, so subgraph querying has been attracting more and more attention from researchers around the world. Unfortunately, subgraph querying is very time consuming since it involves subgraph isomorphism testing that is known to be an NP-complete problem. In this paper, we propose a novel coding method for subgraph querying that is based on Laplacian spectrum and the number of walks. Our method follows the filtering-and-verification framework and works well on graph databases with frequent updates. We also propose novel two-step filtering conditions that can filter out most false positives and prove that the two-step filtering conditions satisfy the no-false-negative requirement (no dismissal in answers). Extensive experiments on both real and synthetic graphs show that, compared with six existing counterpart methods, our method can effectively improve the efficiency of subgraph querying.

This paper presents Crypto-Tutor, a tool for learning modern cryptographic algorithms. Our tool offers an interactive way to learn about the uses and structure of several popular cryptographic algorithms, as well as the underlying mathematical concepts which guarantee the security of these algorithms. Crypto-Tutor also offers performance benchmarking of the algorithms for several datasets, as well as an interactive environment where the algorithms can be executed for custom input and configuration. This tool was used in the classroom, as part of two undergraduate courses in the Faculty of Technical Sciences, University of Novi Sad. Here we also present our experiences with using Crypto-Tutor in the classroom, and formally evaluate the usefulness of this tool.
Pulmonary Embolism: Optimizing the Diagnostic Imaging Approach

Abstract Venous thromboembolism is a common medical problem that can affect a wide range of patients. The clinical presentation ranges from minor, nonspecific signs and symptoms to severe clinical scenarios. The combination of objective pretest clinical probability, D-dimer testing, and imaging studies plays a critical role in its diagnosis. There are multiple imaging modalities to confirm or exclude the presence of pulmonary embolism and deep vein thrombosis, but, at present, computed tomography angiography is the most frequently used. Other imaging, however, is required for several subpopulations.
Lon Protease Degrades Transfer-Messenger RNA-Tagged Proteins

ABSTRACT Bacterial trans translation is activated when translating ribosomes are unable to elongate or terminate properly. Small protein B (SmpB) and transfer-messenger RNA (tmRNA) are the two known factors required for and dedicated to trans translation. tmRNA, encoded by the ssrA gene, is a bifunctional molecule that acts both as a tRNA and as an mRNA during trans translation. The functions of tmRNA ensure that stalled ribosomes are rescued, the causative defective mRNAs are degraded, and the incomplete polypeptides are marked for targeted proteolysis. We present in vivo and in vitro evidence that demonstrates a direct role for the Lon ATP-dependent protease in the degradation of tmRNA-tagged proteins. In an endogenous protein tagging assay, lon mutants accumulated excessive levels of tmRNA-tagged proteins. In a reporter protein tagging assay with λ-CI-N, the protein product of a nonstop mRNA construct designed to activate trans translation, lon mutant cells efficiently tagged the reporter protein, but the tagged protein exhibited increased stability. Similarly, a green fluorescent protein (GFP) construct containing a hard-coded C-terminal tmRNA tag (GFP-SsrA) exhibited increased stability in lon mutant cells. Most significantly, highly purified Lon preferentially degraded the tmRNA-tagged forms of proteins compared to the untagged forms. Based on these results, we conclude that Lon protease participates directly in the degradation of tmRNA-tagged proteins.
Multiplex PCR for the detection of BCL-1/IGH and BCL-2/IGH gene rearrangements – clinical validation in a prospective study of blood and bone marrow in 258 patients with or suspected of non-Hodgkin's lymphoma.

We have designed a multiplex PCR, which allows for fast and high throughput demonstration of the BCL-1/IGH and BCL-2/IGH fusion DNA observed primarily in mantle cell- and follicular non-Hodgkin's lymphoma (NHL). Blood (PB) and/or bone marrow (BM) from 258 patients suspected of NHL have prospectively been evaluated. Eleven patients (4%) were found t(11;14)+ and 37 patients (14%) t(14;18)+. Comparing these results to standard diagnostic methods of PB and/or BM identified PCR+ samples that were normal by morphology (BCL-1/IGH: 1/11; BCL-2/IGH: 17/37). Equally important, patients who were not clonal in PB and/or BM by flow cytometry were identified as PCR+ (BCL-1/IGH: 3/11; BCL-2/IGH: 23/37). We conclude that this multiplex approach allows for easy and sensitive molecular determination of molecular lesions in NHL, which have diagnostic and prognostic importance.
Robust Adaptive Control of Cooperating Mobile Manipulators With Relative Motion

In this paper, coupled dynamics are presented for two cooperating mobile robotic manipulators manipulating an object with relative motion in the presence of uncertainties and external disturbances. Centralized robust adaptive controls are introduced to guarantee the motion, and force trajectories of the constrained object converge to the desired manifolds with prescribed performance. The stability of the closed-loop system and the boundedness of tracking errors are proved using Lyapunov stability synthesis. The tracking of the constraint trajectory/force up to an ultimately bounded error is achieved. The proposed adaptive controls are robust against relative motion disturbances and parametric uncertainties and are validated by simulation studies.
Mammalian Sprouty-1 and -2 Are Membrane-Anchored Phosphoprotein Inhibitors of Growth Factor Signaling in Endothelial Cells

Growth factor–induced signaling by receptor tyrosine kinases (RTKs) plays a central role in embryonic development and in pathogenesis and, hence, is tightly controlled by several regulatory proteins. Recently, Sprouty, an inhibitor of Drosophila development-associated RTK signaling, has been discovered. Subsequently, four mammalian Sprouty homologues (Spry-1–4) have been identified. Here, we report the functional characterization of two of them, Spry-1 and -2, in endothelial cells. Overexpressed Spry-1 and -2 inhibit fibroblast growth factor– and vascular endothelial growth factor–induced proliferation and differentiation by repressing pathways leading to p42/44 mitogen-activating protein (MAP) kinase activation. In contrast, although epidermal growth factor–induced proliferation of endothelial cells was also inhibited by Spry-1 and -2, activation of p42/44 MAP kinase was not affected. Biochemical and immunofluorescence analysis of endogenous and overexpressed Spry-1 and -2 reveal that both Spry-1 and -2 are anchored to membranes by palmitoylation and associate with caveolin-1 in perinuclear and vesicular structures. They are phosphorylated on serine residues and, upon growth factor stimulation, a subset is recruited to the leading edge of the plasma membrane. The data indicate that mammalian Spry-1 and -2 are membrane-anchored proteins that negatively regulate angiogenesis-associated RTK signaling, possibly in a RTK-specific fashion.
An Indonesian-version of the short attitude toward mathematics inventory: a voice from pre-service chemistry teacher

This study aimed to examine the validity of the Indonesian version of the short attitude toward mathematics inventory (ATMI). The adapted inventory was also used for further analysis to explore mathematics attitude of pre-service chemistry teachers across gender. The original ATMI was translated into Bahasa and distributed to 328 participants via the online survey. After preliminary checking for multivariate outliers, all the data were used to analyze the construct validity of structural model using confirmatory factor analysis (CFA). Furthermore, multigroup analysis with structured mean modelling was conducted to explore the gender effect toward mathematics attitude. All item means, standard deviations and correlation matrix were also explored. The result found that the short form supported the four-factor solution as the original ATMI. Modification indices, standardized regression weight, and squared multiple correlations were used to determine which items to be removed or retained during analysis until standard criteria for model fit reached. This items deletion produced a shorter version of ATMI (19 items) with fairly good internal consistency, both for all items inventory (α=0.92) or for individual subscale (mean α=0.86). Moreover, the t-test on the latent mean value showed no significant difference of attitude toward mathematics between male and female.
Centennial to millennial hydroclimatic fluctuations in the humid northeast United States during the Holocene

Abstract Paleoclimate records indicate that the hydroclimate of the northeast United States changed continuously during the Holocene, but the signals of multi-century variations have been difficult to distinguish from local effects and noise. Systematic replication of the signals can help diagnose the patterns of change. Here, we use ground-penetrating radar (GPR) and sediment core analyses to extend and compare the regional network of lake-level records. We reconstruct the histories of two lakes in northeast Pennsylvania, which show that multi-century hydrologic changes observed in coastal New England extended to the Susquehanna River watershed. Correlations with isotopic and marine temperature records (r>0.65) indicate that high temperatures coincided with low water at 4.9–3.8 and 2.8–2.0 ka. Widely recognized Holocene events at ca. 4.2 and 2.7 ka, therefore, may have shared similar ocean-atmosphere dynamics in this region. Low water levels in Pennsylvania from ca. 5.5–4.9 ka, however, demonstrate that other multi-century changes had different patterns. At ca. 5.5 ka, anti-phased inland and coastal hydrologic changes followed a sharp temperature decline and produced drought possibly as far inland as the Great Lakes. The long-term increase in water levels since then underscores that current pluvial conditions in the region probably lack a Holocene precedent.
Data Collection by a Mobile Observer in a Single-hop Sensor Network

In this paper, we demonstrate significant reduction in communication power by using a mobile observer to collect data from a wireless single-hop network of static sensors. The key challenge in using a mobile observer is that it remains within range of any sensor for a limited period, and inability to transfer data in this period causes data loss. This prompts us to choose the fraction of nodes successful in communicating data as our performance constraint as we try to minimize network power. First, we establish that the process of data collection by a mobile observer is analogous to a queue. The queuing-based data collection model is then used as a design tool to identify the combination of system parameters that satisfies the performance metric with minimum power. Second, we derive a sufficient condition on node placement for zero data loss in a mobile observer network. As our third contribution, we demonstrate that in a dense network, the data collection analysis is much simpler, which allows us to obtain closed expressions for the network power. Power comparisons with static observer networks show that power reduction by multiple orders of magnitude is typical. The scenarios chosen for power comparisons also provide guidelines on the choice of path, if such a choice is available. As an example, a disc shaped network is analyzed and among the set of concentric circular paths, the best path is identified.
Comparison of Siglec-1 protein networks and expression patterns in sperm and male reproductive tracts of mice, rats, and humans

Background and Aim: Sialic acid-binding immunoglobulin-like lectin 1 (Siglec-1) is a transmembrane glycoprotein involved in the sialic acid (Sia)-dependent regulation of the immune system. Siglec-1 expression has recently been identified in the male reproductive tract (MRT) of several species, including humans, cattle, horses, and sheep, and may play a role in modulating fertility in a Sia-dependent manner. Materials and Methods: In this study, proteinâ€“protein interaction (PPI) analysis of Siglec-1 was conducted to identify associated network protein conservation, and the expression of Siglec-1 in the MRT of mice and rats, including their accessory sex glands and spermatozoa was determined by immunostaining. Results: Network analysis of proteins with Siglec-1 in mice and rats demonstrated significant similarity to human Siglec-1 networks, suggesting a similar conservation of network proteins between these species and, hence, a potential conservation role in immune modulation and function. Specific immunostaining patterns of mouse and rat testes, epididymis, ductus deferens, accessory sex gland tissues, and sperm were detected using human Siglec-1. These results confirmed that the human Siglec-1 antibody could cross-react with mouse and rat Siglec-1, suggesting that the specific expression patterns of Siglec-1 in the MRT and sperm of both mice and rats are similar to those observed in other species. Conclusion: The conservation of Siglec-1 expression patterns in sperm and within the MRT and the similarity of protein networks for Siglec-1 across species suggest that Siglec-1 may function in a similar manner across species. These results also suggest that rodents may serve as a valuable model system for exploring the function of Siglecs in the reproductive system across species and their potential role in modulating fertility in a Sia-dependent manner. Keywords: female reproductive tract, male reproductive tract, proteinâ€“protein interaction, sialic acid, sialic acid-binding immunoglobulin-like lectin-1.
