Fisher Discriminant Analysis for Extracting Interpretable Phenological Information from Multivariate Time Series Data
Authors: Doherty Conor , Mauter Meagan
Published: October 2022

For many applications in environmental remote sensing, the interpretation of a given measurement depends strongly on what time of year the measurement was taken. This is particularly the case for phenology studies concerned with identifying when plant developmental transitions occur, but it is also true for a wide range of applications including vegetation species classification, crop yield estimation, and more. This study explores the use of Fisher Discriminant Analysis (FDA) as a method for extracting time-resolved information from multivariate environmental time series data. FDA is useful because it can be applied to multivariate input data and, for phenological estimation problems, produces a transformation that is physically interpretable. This work contains both theoretical and applied components. First, we use FDA to demonstrate the time-resolved nature of phenological information. Where curve-fitting and other commonly used data transformations that are sensitive to variation throughout a full time series, we show how FDA identifies application-relevant variation in specific variables at specific points in time. Next, we apply FDA to estimate county-average corn planting dates in the United States corn belt. We find that using multivariate data inputs can reduce prediction RMSE (in days) by 20% relative to models using only univariate inputs. We also compare FDA (which is linear) to nonlinear planting date estimation models based on curve-fitting and random forest estimators. We find that multivariate FDA models significantly improve on univariate curve-fitting and have comparable performance when using the same univariate inputs (despite the linearity of FDA). We also find that FDA-based approaches have lower RMSE than random forest in all configurations. Finally, we interpret FDA coefficients for individual measurements sensitive to vegetation density, land surface temperature, and soil moisture by relating them to physical mechanisms indicative of earlier or later planting.
GANSim-surrogate: An integrated framework for conditional geomodelling and uncertainty analysis
Authors: Song Suihong , Zhang Dongxiao , Mukerji Tapan , Wang Nanzhe
Published: October 2022

We propose a deep-learning framework (GANSim-surrogate) for conditioning subsurface geomodel realizations to static data and dynamic flow data. The static data includes well facies data, interpreted facies probability maps, and non-spatial global features, while dynamic data can include well data such as pressures and flow rates. The framework consists of a Convolutional Neural Network (CNN) generator trained from GANSim (a Generative Adversarial Network-based geomodelling simulation approach), a CNN-based surrogate, and options for searching appropriate input latent vectors for the generator. The four search methods investigated are Markov Chain Monte Carlo, Iterative Ensemble Smoother, gradient descent, and gradual deformation. The framework is validated by applying it for geomodelling of channelized reservoirs. First, a generator is trained using GANSim to generate geologic facies models; in addition, a flow simulation surrogate is trained using a physics-informed approach. Then, given well facies data, facies probability maps, global facies proportions, and dynamic bottomhole pressure data (BHP), the trained generator takes the first three conditioning data and a latent vector as inputs and produces a random realistic facies model conditioned to the static data. To condition to the dynamic data, the produced facies model is converted to permeabilities and mapped to BHP data by the trained physics-informed surrogate. Finally, the mismatch between the surrogate-produced and the observed BHP data is minimized to obtain appropriate input latent vectors for the generator. The framework is computationally efficient, and the posterior facies models prove to be realistic and consistent with all of the conditioning data.
Hybrid powerplant configuration model for marine vessel equipped with hydrogen fuel-cells
Authors: Balestra Lorenzo , Schjølberg Ingrid
Published: October 2022

The transport sector is investing in new technologies, shifting towards zero-emission propulsion systems. This shift can be observed in the automotive transport sector, but also in maritime transport, where shipowners are evaluating new powertrain configurations and less polluting energy carriers. The innovation in this field is aided by the development of software, based on simulation models representing the powertrain. In this paper, a quasi-static model for a hybrid powerplant is presented. The focus is on hybrid solutions utilizing proton exchange membrane hydrogen fuel cells and batteries. This model can aid the design of powerplants for new hybrid vehicles, or older ones waiting for a retrofit. The model is converted into a Matlab software application for ease of use. Results produced by the model define the powerplant composition and a series of factors, such as fuel cell degradation and hydrogen consumption, that have an influence on running costs. The functionalities of the Matlab software application based on the quasi-static model are demonstrated via one case study considering a harbor tugboat. The results obtained can also be used to measure the technical and economic feasibility of powertrain configurations. The presented model does not include effects related to components aging as all the hardware is considered at beginning of life.
Are there independent effects of constraint and predictability on eye movements during reading?
Authors: Wong Roslyn , Veldre Aaron , Andrews Sally
Published: October 2022

Evidence of processing costs for unexpected words presented in place of a more expected completion remains elusive in the eye-movement literature. The current study investigated whether such prediction error costs depend on the source of constraint violation provided by the prior context. Participants’ eye movements were recorded as they read predictable words and unpredictable alternatives that were either semantically related or unrelated in three-sentence passages. The passages differed in whether the source of constraint originated solely from the global context provided by the first two semantically rich sentences of the passage; from the local context provided by the final sentence of the passage; from both the global and local context; or from none of the three sentences of the passage. The results revealed the expected processing advantage for predictable completions in any constraining context, although the relative contributions of the different sources of constraint varied across the time course of word processing. Unpredictable completions, however, did not yield any processing costs when the context constrained towards a different word, instead producing immediate processing benefits in the presence of any constraining context. Moreover, the initial processing of related unpredictable completions was enhanced further by the provision of a supportive global context. Predictability effects therefore do not appear to be determined by cloze probability alone but also by the nature of the prior contextual constraint especially when they encourage the construction of higher-level discourse representations. The implications of these findings for understanding existing theoretical models of predictive processing are discussed.

Artykuł porusza problematykę przestępstw seksualnych duchownych Kościoła rzymskokatolickiego. Zawiera próbę przybliżenia samej skali zjawiska przestępstw seksualnych popełnianych przez duchownych w świetle dostępnych statystyk i literatury, z uwzględnieniem wybranych krajów oraz Polski, jak również wskazania przykładów reakcji Kościoła i państwa na ten problem. Przedstawione są także czynniki kryminogenne przestępczości seksualnej w Kościele, takie jak: tzw. "kultura klerykalna", sam stan duchowny jako czynnik ryzyka, celibat duchownych oraz orientacja homoseksualna sprawców. Opracowanie porusza również prawnokarne aspekty przestępstw seksualnych duchownych, a w szczególności problematykę karalnego zaniechania denuncjacji, co ma szczególne znaczenie w świetle kierowanych pod adresem Kościoła zarzutów o "tuszowanie" przestępstw seksualnych popełnionych przez duchownych lub pomaganie sprawcom w uniknięciu odpowiedzialności.
Kolizja aksjologiczna prawa karnego z prawem upadłościowym jako skutek zmiany tytułu rozdziału XXXVI Kodeksu karnego
Authors: Grabarek Dariusz
Published: October 2022

Wskazane w tytule rozdziału części szczególnej Kodeksu karnego rodzajowe dobro prawne implikuje wykładnię przepisów w nim zawartych. Od 25 maja 2019 roku ustawodawca, poprzez zmianę tytułu rozdziału XXXVI tego kodeksu na „Przestępstwa przeciwko obrotowi gospodarczemu i interesom majątkowym w obrocie cywilnoprawnym”, dokonał poszerzenia rodzajowego przedmiotu ochrony, skutkiem którego przestało mieć znaczenie, czy dane zachowanie będzie mieć miejsce w obrocie gospodarczym (jak uprzednio), czy też w obrocie cywilnoprawnym, w którym po obu stronach występować będą nieprofesjonaliści. Sąd Najwyższy zauważył, że spowoduje to nieuniknioną „rewolucję” w wykładni przepisów tego rozdziału. Między innymi dotyczy to czynów stypizowanych w art. 301 Kodeksu karnego, sankcjonujących doprowadzenie dłużnika do swojej upadłości lub niewypłacalności, zatem penalizacją, jako podmiot przestępstwa, zostanie objęty również „konsument”. Jednocześnie ustawodawca w prawie insolwencyjnym, a konkretnie w ustawie Prawo upadłościowe, otworzył dostęp do oddłużenia także i tym dłużnikom „konsumentom”, którzy doprowadzili do swojej niewypłacalności lub istotnie zwiększyli jej stopień umyślnie lub wskutek rażącego niedbalstwa. Przewidziano możliwość oddłużenia nawet wówczas, gdy taki dłużnik działał w sposób celowy. Autor wykazał, że doszło skutkiem tego do rozdźwięku pomiędzy prawem karnym, a prawem upadłościowym i kolizji aksjologicznej w systemie prawa, która ma miejsce wówczas, kiedy ustawodawca w jednej normie wyżej ceni daną wartość niż w innej, a w drugiej normie czyni odwrotnie. Zdaniem autora nie dojdzie do derogacji części norm przez ustawodawcę, a reguły kolizyjne nie będą mieć tu zastosowania. Konieczna będzie wykładnia przepisów karnych oparta na paradygmacie domniemania racjonalności ustawodawcy oraz subsydiarności prawa karnego.
"What activism can learn from poetry": Lyric Opacity and Drone Warfare in Solmaz Sharif’s LOOK
Authors: Finberg Keegan Cook
Published: October 2022

The essay explores whether concealing humanness or emphasizing humanness is a more effective strategy for anti-drone activism that seeks to disrupt the conventional epistemologies of militarized surveillance. Building on Édouard Glissant’s decolonizing philosophy of relation and more recent theories of gender and surveillance such as Rachel Hall’s notion of “animal opacity,” the essay argues that poetry is one place we might find an answer to what seems like a binary problem of seeing versus unseeing humanity in technologically mediated aerial warfare. I illustrate that the 2016 poetry collection LOOK by Solmaz Sharif intervenes to suggest activism that steers readers away from the logics of recognition and toward the ethical potential of concealment. LOOK garners formal elements from lyric and experimental poetry traditions to employ a strategy of resistance-looking based in multiple valences of opacity.multiple valences of opacity.
Feminist Conspiracies, Security Aunties, and Other Surveillance State Fictions
Authors: Stuelke Patricia
Published: October 2022

This article investigates two recent fictional representations of the feminized US surveillance state and its “security feminists” (Grewal), with an eye towards limning what visions of social transformation and political life such representations make possible. It first examines Gish Jen’s 2020 novel The Resisters, considering how the novel’s characterization of the US surveillance state as a snoopy suspicious Aunt maintains American liberal fantasies about the value of productive work and institutionally-sanctioned responses to state violence, even as the novel attempts to find grounds for reinvigorating a democratic commons. Jeff Vandermeer’s 2021 novel Hummingbird Salamander, in contrast, is suspicious of democratic visions of the social. Instead, the novel unravels the privatized figure of the “security mom” (Grewal) in order to experiment with how a queer antisocial orientation might confront environmental and institutional collapse and reimagine the idea of “security” itself.

An important detail of the energy management system (EnMS) are measures to save energy resources and establish basic levels of energy consumption at different stages of the enterprise: monitoring energy consumption and product energy capacity, analysis of existing indicators, energy policy development and planning current and future measures aimed at high economic efficiency. activities of the enterprise. The authors of the article developed a method for determining the energy intensity of products for a particular enterprise, which can be extended to any poultry farm and reflects the following: norms of electricity and heat consumption per unit of production, as well as electricity and fuel consumption rates These indicators are the basic levels that need to be taken into account when calculating the energy efficiency of the entire enterprise, which will better assess the savings from energy efficiency measures. These indicators are benchmarks for assessing the current state of the enterprise and for future periods, taking into account changes in production volumes, the introduction of new technological processes, the implementation of energy saving measures and more. Energy intensity of products is an indicator used to assess the energy efficiency of poultry farms during energy audits under the auspices of international financial organizations, which allows the company to enter international markets and thus improve the efficiency of economic activity.

The calculation of energy intensity of products was carried out on the example of the factory of PJSC "Agrofirma Berezanska poultry farm" located in Berezan, Baryshiv district, Kyiv region. The company produces eggs, poultry and egg powder.

The following indicators of energy intensity of production are calculated:

norms of consumption of electricity, heat and cold for the production of eggs, meat and egg powder;
rate of fuel and electricity consumption for heat supply by heat generators, boiler room and mini-boiler rooms;
rate of electricity consumption for cold production.
These indicators are indicators of energy efficiency of the enterprise, which are developed taking into account the technical characteristics of the equipment, its operating time, climatic conditions, etc. These indicators will be used to assess the energy efficiency of technological and ancillary equipment in the future, as well as the boiler company that releases thermal energy.
EXPERIMENTAL INVESTIGATION OF ENERGY LOSSES OF A BIOGAS REACTOR IN THE ENVIRONMENT FOR MESOPHILIC MODE OF FERMENTATION
Authors: Zablodskiy M. , Spodoba M. , Spodoba O.
Published: October 2022

The aim of the work is an experimental study of energy losses to the environment for the mesophilic mode of fermentation in order to increase the duration of substrate cooling and reduce energy costs for the process of biogas formation. To achieve the goals set, the following tasks have been solved: a methodological approach has been developed for conducting experimental studies; an experimental plant for a biogas reactor with an electrothermal-mechanical system with automatic control for mixing and heating the substrate was made; experimentally investigated energy losses to the environment for the mesophilic mode of fermentation; processing, analysis and comparison of the obtained experimental data were carried out. The working hypothesis of the research was that the use of an heating cable built into the stirrer paddles would provide a longer process of cooling the substrate to the heating switch-on temperature, which would reduce energy costs for the biogas formation intensification process. The most significant result of the study is to obtain the dependences of the change in the temperature of the heating cable, the substrate in the lower, middle and upper tiers of the reactor and the duration of the substrate cooling to the heating switch-on temperature in the operating biogas plant. The significance of the results of experimental studies lies in the fact that when placing a heating cable built into the stirrer paddles, the process of cooling the substrate to the heating switch-on temperature occurs later, on average, by 35 minutes, when the substrate is fermented in a biogas reactor with a volume of 40 liters. The implementation of the data obtained will increase the energy efficiency of the processes of intensification of biogas production and the profitability of further processing of biogas into heat and electricity.
IMPROVING THE AERODYNAMIC CHARACTERISTICS OF THE DRYING PROCESS BASED ON THE LOCAL APPROACH
Authors: Suprun T.
Published: October 2022

In modern conditions, energy-saving technologies are widely used in various technological processes, including drying processes. Energy saving is achieved in various ways, including through the recycling of waste from the original product, in particular, dried plant waste.

The object of this study is the coolant supply system of the installation for drying and technological conditioning of plant waste.

The purpose of the work is to develop methods for improving the aerodynamic characteristics of the coolant supply system based on local control of thermophysical parameters in characteristic zones of the working environment.

Physical modeling is a traditional method used in IET NAS of Ukraine to study the transfer processes typical for heat power equipment.

The research was carried out in a specially made experimental sample of the installation, which completely reproduces the operating conditions of the full-scale installation in terms of geometric parameters and air supply system. The main difference was that the experiments were performed without heating the coolant (air) and using a fixed working line. The material to be dried was placed on a horizontal working line in the form of a thin layer and was blown by vertical air jets.

To assess the uniformity of the velocity field, the hot-wire method of measurements was used. Simultaneously with the values of the time-averaged velocity, the method makes it possible to determine the value of longitudinal fluctuations, which have a significant effect on the intensity of heat and mass transfer processes.

Based on the local control of the measurement results in the characteristic zones of the working space of the installation, measures were developed aimed at improving the uniformity of the flow velocity fields due to design changes in the air supply system. When performing the work, eight modifications were implemented, differing both in design features and for information received.

Because of the measures taken to improve the aerodynamic characteristics of the coolant supply system, it was possible to achieve optimal values of the average velocity and its non-uniformity coefficient, which ensure the required quality of material processing.
ELECTION OF CRITERIA FOR ASSESSMENT OF SUSTAINABILITY IN THE DESIGN OF TECHNOLOGICAL SYSTEMS FOR BIOGAS PRODUCTION
Authors: Ramsh V. , Potapenko M. , Sharshon V.
Published: October 2022

One of the most promising renewable energy sources is the production of biogas from waste and its further use.

The stability of technological systems for biogas production is described by a set of quantitative indicators that depend on the structure, operation algorithm and stability indicators of individual elements.

When developing technological control systems for biogas plants, it is necessary to solve a whole range of tasks related to the processing of initial information for the analysis and synthesis of optimal system options.

The aim of the study is to develop a methodology for determining the stability of the automatic control system for biogas production processes as an integral part of the technological system, which makes it possible to formalize quantitative and qualitative characteristics and create an algorithmic and software base for calculations.

Since the technological control systems of biogas plants are nonlinear control objects, then to study their operation, linearization is provided within the basic mode, while the mode specified by the optimizer is within the linearization error.

Design problems are solved in the presence of analytical dependences of the stability characteristics of the system on the stability characteristics of objects.

Considering that the interacting elements of the systems are individual types of equipment and various types of raw materials and energy carriers involved in technological processes, a large number of information materials should be used when operating equipment of biogas plants.

When designing a technological system for biogas production for a specific object, it is necessary to create its conditionally complete dynamic model, and using the model, calculate matrices for various operating modes and determine the boundaries of the spectra of eigenvalues and consider options for matching the regulator with the object. Considering approximately the same costs, the preferred option should be considered the option that provides the greatest margin of stability.

Penggunaan lampu LED untuk pencahayaan ruangan banyak digunakan di bangunan-bangunan gedung ataupun rumah tangga. Lampu LED memiliki tingkat efikasi cukup tinggi dibanding dengan jenis lampu LHE.

Lampu LED dipasaran dijual dengan beberapa merk, dengan lebel daya yang bervariasi serta tingkat efikasi yang berbeda pula. Kegeragaman spesifikasi lampu LED yang beredar dipasaran membuat konsumen perlu mengetahui kualitas lampu LED. Tingkat efikasi berpengaruh terhadap besarnya daya yang diperlukan untuk memenuhi tingkat pencahayaan standar ruangan. Oleh karena itu perlu dilakukan penelitian, untuk mengetahui tingkat efikasi LED yang ada dipasaran, khususnya yang paling banyak digunakan.

Dari hasil pengujian, pengukuran dan perhitungan yang dilakukan pada tiga sampel merk lampu LED yang ada dipasaran didapat bahwa, tingkat efikasi lampu LED dalam satu merk tidaklah sama, juga tingkat efikasi LED untuk daya yang sama dari beberapa merk tidaklah sama.

One of the requirements for graduation in the diploma III study program at the State Polytechnic of Pontianak is the making of a final project which process starts at the beginning of semester 6. Students need to take steps to complete the final project starting with submitting titles, proposals, submitting supervisors, and consulting with supervisor. At present the process of these stages is still being carried out manually, with time constraints and the ongoing spread of the covid-19 virus (corona virus) so that the Government issues PPs, Circular Letters and urges to implement social distancing and physical distancing, so the manual process does not run automatically optimal, the reason is that students have not been able to meet prospective supervisors, supervisors also have the desire to choose prospective students to be mentored, and consult with supervisors to get input and corrections related to the design and process of the final project. From these problems, it is necessary to build a final project information system that is made web-based with a codeigniter framework with supporting technology for AJAX, JavaScript and Mysql as a Database Management System. This system has three user entities, namely students, supervisors and administrators. This system is capable of serving title proposals, proposals, submission of supervisors, selection of students to be mentored, and media consultations between students and supervisors for smooth online and realtime final project processes.
