A Queer Search for Ancestral Legitimacy
Authors: Collay Jay
Published: August 2022

The practice among queer people of compiling lists of famous historical figures that modern eyes may comfortably identify as queer and/or trans* persists, and has persisted, as a form of communal transmission of memory for over a century and a half. These collections of names, described in this article as ‘gay lists’ in the spirit of their frequently casual deployment, acted as a key element of queer history and memory well before the Stonewall Uprising rooted itself in the popular consciousness as the beginning of queer history. This article explores English-language primary texts published in the US, the UK, and Italy between the mid-nineteenth and mid-twentieth centuries including personal statements in homophile magazines and Edward Prime-Stevenson’s book The Intersexes. The purpose of examining these texts is to discuss how gay lists were deployed to create a sense of a queer collective, a claim to history, and an imagination of ancestry in the wider consciousness. This article distinguishes lists naming recognizable historical figures from evocations of Greco-Roman mythology or Biblical antiquity. It also summarizes a brief selection of published literature describing the phenomenon so far and makes a case for exploring gay lists as a study in revisionist and popular historical memory.
O Geossistema pela Complexidade: sobre totalidades e o reducionismo do humano pelo natural
Authors: Gomes Rodrigo Dutra
Published: August 2022

As totalidades e a perspectiva naturalista são algumas das principais características dos estudos dos Geossistemas. Pelas leituras clássicas de V. Sotchava e G. Bertrand o geossistema é um fenômeno natural e uma totalidade objetiva. Isso é expressão da concepção de totalidade e naturalismo herdados da ciência do XIX, neste último caso dando também a tonalidade do reducionismo e dificuldade do estudo do humano no modelo. Contudo, o contexto da Complexidade vem destacando sentidos mais relacionais e menos rígidos sobre a concepção de totalidade, e sentidos complementares entre humano e natural no modelo. O objetivo deste artigo foi discutir as totalidades geossistêmicas e o problema do reducionismo do humano ao natural no geossistema em diálogo com a Teoria da Complexidade. A análise foi feita pelo discernimento das proposições de totalidade e críticas ao naturalismo pela Complexidade e possíveis repercussões para as proposições geossistêmicas. Como resultado, as totalidades geossistêmicas se tornam relacionais e os humanos não podem ser visto apenas como “perturbadores’ e passam a ser integrantes das relações internas do geossistema.

Authors: Vinhaes Alan Da Silva , Hespanhol Antonio Nivaldo
Published: August 2022

A agricultura urbana está integrada ao ecossistema urbano, tem caráter multifuncional e propicia bons resultados ambientais, sociais e econômicos. Atualmente, a agricultura urbana está ganhando destaque nos cenários brasileiro e mundial, sendo importante compreender as iniciativas e demandas existentes para que políticas públicas adequadas possam ser implementadas. Nesse sentido, o objetivo principal do artigo é compreender e analisar as práticas da agricultura urbana em Porto Ferreira/SP. Para a consecução do objetivo da investigação, foram realizados pesquisa bibliográfica, trabalho de campo, com aplicação de formulário a agricultores urbanos a fim de compreender o papel e o perfil dos atores pesquisados, além de entrevistas com feirantes, comerciantes de mudas e autoridades municipais. Concluiu-se que, no caso de Porto Ferreira, as hortas urbanas promovem a inclusão social de pessoas de baixa renda, desempregados, idosos e mulheres, pois, no universo de 60 agricultores urbanos pesquisados, 55 destinam o que produzem ao autoconsumo e/ou a vendas nos próprios locais de produção, enquanto dois comercializam seus produtos na feira livre da cidade e três, diretamente a supermercados. Ficou demonstrado, igualmente, a necessidade de fomentar e reconhecer o potencial das hortas urbanas como ferramenta para geração de renda complementar, interação social dos agricultores urbanos envolvidos e, principalmente, o resgate cultural da produção de alimentos para consumo próprio.

Sensitivity studies of nighttime TOA radiances from artificial light sources using a 3-D radiative transfer model for nighttime aerosol retrievals

Published: August 2022

Abstract. By accounting for surface-based light source emissions and Top-of-Atmosphere (TOA) downward lunar fluxes, we adapted the Spherical Harmonic Discrete Ordinate Method (SHDOM) 3-dimentional (RTM) radiative transfer model (RTM) to simulate nighttime 3-D TOA radiances as observed from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day-Night-Band (DNB) onboard the Suomi-NPP satellite platform. Used previously for daytime 3D applications, new SHDOM enhancements allow for the study of the impacts of various observing conditions and aerosol properties on simulated VIIRS-DNB TOA radiances. Observations over Dakar, Senegal, were investigated for potential applications and opportunities for using observed radiances containing VIIRS-DNB ‘bright pixels’ from artificial light sources to conduct aerosol retrievals. We found that using the standard deviation (STD) of such bright-pixels provided a more stable quantity for nighttime aerosol optical depth (AOD) retrievals than direct retrievals from TOA radiances. Further, both the mean TOA radiance and STD of TOA radiances over artificial sources are significantly impacted by satellite viewing angles. Light domes, the enhanced radiances adjacent to artificial light sources, are strong functions of aerosol properties and especially aerosol vertical distribution, which may be further utilized for retrieving aerosol layer height in future studies. Through inter-comparison with both day- and night-time Aerosol Robotic Network (AERONET) data, the feasibility of retrieving nighttime AODs using 3-D RTM SHDOM over artificial light sources was demonstrated. Our study shows strong potential for using artificial light sources for nighttime AOD retrievals, while also highlighting larger uncertainties in quantifying surface light source emissions. This study underscores the need for surface light emission source characterizations as a key boundary condition, which is a complex task that requires enhanced input data and further research. We demonstrate how quality-controlled nighttime light data from the NASA’s Black Marble product suite could serve as a primary input into estimations of surface light source emissions for nighttime aerosol retrievals.
Semi-continuum modelling of unsaturated porous media flow to explain the Bauters' paradox
Authors: Kmec Jakub , Šír Miloslav , Fürst Tomáš , Vodák Rostislav
Published: August 2022

Abstract. In gravity-driven free infiltration of a wetting liquid into a homogeneous unsaturated porous medium, the flow pattern is known to depend significantly on the initial saturation. Point-source infiltration of a liquid into an initially dry porous medium produces a single finger with an oversaturated tip and an undersaturated tail. In an initially wet medium, a diffusion-like plume is produced with a monotonic saturation profile. We present a semi-continuum model based on a proper scaling of the retention curve which is discrete in space and continuous in time. We show that the semi-continuum model is able to describe this transition and to capture the experimentally observed dependence of the saturation overshoot and the finger velocity on the initial saturation.
RF-interference detection and mitigation in the DWD C-Band weather radar network
Authors: Schaper Maximilian , Frech Michael , Michaelis David , Hald Cornelius , Rohrdantz Benjamin
Published: August 2022

Abstract. C-Band weather radar data are commonly compromised by interference from external sources even though weather radars are the primary and therefore privileged user of this frequency band. This is also the case for the radar network of the German Weather Service (Deutscher Wetterdienst, DWD). Theoretically, dynamic frequency stepping (DFS) by devices operating in the C-Band should prevent any disturbance of the primary user. In practice, this does not always work as intended by the current regulations. As it is not possible to separate a superimposed interference signal from measured weather radar data, the protection of the frequency band is of utmost importance. Currently the only available option is to discard the compromised portions of the radar data. Therefore, the current best course of action is to shut down interference (RFI) sources as fast as possible. The automated RFI detection algorithm for the German C-Band weather radar network is operational since July 2017, which makes use of routinely measured radar moments. Built upon the data gathered since 2017, an RFI classification with respect to the severity and duration of RFIs was first implemented in 2019. An independent verification of the RFI detection algorithm was performed by using a commercially available WIFI adapter, which is directly integrated into the radar receiver. Subsequently, a mitigation workflow was implemented to efficiently identify and shut down detected RFI sources by the German Federal Network Agency (BNetzA). By following this workflow with great effort, the number of persistent RFIs is decreasing since October 2019 while a steady increase in short lived RFIs over the last 5 years exists. In total, 11889 RFIs have been identified since July 2017 until May 2022. The majority of these (94.8 %) are so short lived that an unambiguous identification by the BNetzA is, in general, not feasible. However, as stated by the C-Band regulations, any non-compliant transmitter compromising the operation of a weather radar has to be shut down. This is important, as even these short lived RFIs negatively affect the meteorological product generation.
Bayesian method for estimating Weibull parameters for wind resource assessment in the Equatorial region: a comparison between two-parameter and three-parameter Weibull distributions
Authors: Khan M. Golam Mustafa , Ahmed M. Rafiuddin
Published: August 2022

Abstract. The two-parameter Weibull distribution has garnered much attention in the assessment of wind energy potential. The estimation of the shape and scale parameters of the distribution has brought forth a successful tool for the wind energy industry. However, it may be inappropriate to use the two-parameter Weibull distribution to assess energy at every location, especially at sites where low wind speeds are frequent, such as the Equatorial region. In this work, a robust technique for wind resource assessment using a Bayesian approach for estimating Weibull parameters is first proposed. Secondly, the wind resource assessment techniques using a two-parameter Weibull distribution and a three-parameter Weibull distribution, which is a generalized form of two-parameter Weibull distribution, are compared. Simulation studies confirm that the Bayesian approach seems a more robust technique for accurate estimation of Weibull parameters. The research is conducted using data from seven sites in Equatorial region from 1° N of Equator to 21° South of Equator. Results reveal that a three-parameter Weibull distribution with non-zero shift parameter is a better fit for wind data having a higher percentage of low wind speeds (0–1 m/s) and low skewness. However, wind data with a smaller percentage of low wind speeds and high skewness showed better results with a two-parameter distribution that is a special case of three-parameter Weibull distribution with zero shift parameter. The results also demonstrate that the proposed Bayesian approach and application of a three-parameter Weibull distribution are extremely useful for accurate estimate of wind power and annual energy production.
The Golden Candle
Authors: Dash Dionna
Published: August 2022

This story comes from a collection of short stories I wrote this past summer as a Brackenridge Fellow with the Pitt Honors College under the mentorship of Pitt linguistics professor Dr. Abdesalam Soudi. My research during the fellowship combined my interests in linguistics and creative writing by tracing the impact of linguistic discrimination in the college-student population within systems of education and healthcare. Throughout the summer, I conducted a series of focus groups and individual interviews to hear college students’ experiences with language discrimination throughout their lives, which I then crafted into three short fiction stories united under the theme of “The Power of Language.” These stories are amalgamations of multiple informant’s experiences bolstered by my own imaginative story details. They highlight the struggles of both non-native speakers of English and speakers of a non-dominant variety of English, as well as the lack of available translation services in many institutions. These stories also touch on many other complex themes of inclusion, identity, and our perceptions of others. “The Golden Candle” is the second story in this collection.
Evaluation of Drainage Channels on Residential Area
Authors: O.T. Ikotun  , Sartika Dewi
Published: August 2022

The incompatibility of construction of urban or residential drainage channels with design criteria is often found due to difficulties in designing drainage channels.  designers often make design mistakes when designing drainage channels. This study aims to evaluate the drainage system and designs a drainage channel that can collect runoff discharge on Residential Area. The results of flood discharge obtained using the Gumbel method for the 10 and 25 year return periods are 298.78 mm and 370.38 mm. From the calculation of the channel capacity in the field and the discharge plan most of the existing channel capacity cannot accommodate the current planned discharge of 2.261 m3s-1 for the primary channel and 1.824 m3s-1 for the secondary channel. The current channel cannot accept runoff discharge during rain, so the channel rehabilitation plan is carried out by expanding and extracting the dimensions of the drainage channel.
IMPROVING THE EFFECTIVENESS OF EVAPORATION IN SOLAR DISTILLATION UNITS THROUGH AIR FEEDING IN THE EVAPORATION CABIN
Authors: Irwansyah  , Zulfikar  , Asnawi
Published: August 2022

Solar distillation has been used to distill seawater into clean water. The distillation process is largely determined by the effectiveness of the evaporation and condensation processes. This study aimed to investigate the method of condensing air into the water and evaporator space on the effectiveness of the evaporation process. The solar distillation is designed as two units with a single basin type. Type-I solar distillation is designed with the evaporator and condenser chambers in one room. The solar distillation type-II is designed with a modified evaporator chamber so that water vapor can be circulated out and without a condenser room. The solar distillation length and width are 600 mm and 400 mm, respectively, which are made of a 0.6 mm thickness stainless steel plate. At the top, it is covered by a 5 mm thickness glass with a slope of 10°. The test was carried out for 7 days together between the type-I solar distillation and the type-II solar distillation. Data on raw water temperature, room temperature, glass surface temperature, ambient temperature, and solar intensity were recorded during the test. The data is recorded every 30 minutes starting at 08.00 GMT+7 until 17.30 GMT+7. The test results show that the solar distillation performance is influenced by the high and low solar intensity. The volume production of water vapor in the type-II solar distillation is greater than that of the type-I solar distillation. This shows that condensing air into the water and evaporator space can increase the evaporation process's effectiveness on the solar distillation.

PRELIMINARY STUDY OF A IMAGE ANALYSIS SETUP APPROACH OF THERMAL TRACING JET ENGINE PARTS USING THERMAL PAINTS
Authors: S.R. Ghulam  , M. Chandel
Published: August 2022

Reduced engine performance comes with a higher operating temperature, and that limit is imposed by component material life. It is critical to have an accurate, full-field evaluation of the metal temperature of the hot section components for engine designers to develop dependable and lasting engines. Using conventional thermometry isn't recommended since it fails to generate heat gradients and results in problems when transferring data from measurement sites to the readout unit. It has recently been discovered that the thermal transfer condition has changed, and as a result, the actual temperature of the components cannot be measured. A paint will permanently change color if it is exposed to heat, this kind of paint is known as a temperature signaling paint. The traditional method is to test the thermal coatings personally. A manual process of interpretation results in mistakes because there is no accurate detection of isothermal limits that impact human eyesight. A systematic methodology for automated interpretation of thermal paints is detailed in this paper. A technique for orderly picture capture, image segmentation, and image processing, which employs a correct algorithm for surface temperature interpretation, has been addressed.

Published: August 2022

Bridges are connecting access between one region and another, and play an important role in transportation to facilitate community economic activities. The river bridge has very steep cliffs, and these cliffs often occur in landslides, therefore this study is very important to determine the safety of the bridge. This study aims to determine the safety of the bridge abutment structure which is the head of the bridge with the function of continuing the load on the bridge foundation. This analysis is limited to only calculating the stability and safety of bridge abutments with reinforced concrete structures. The analysis uses methods and formulas referring to Indonesian national standards, namely RSNI T-02-2005 regarding loading for bridges, RSNI T-12-2004 concerning concrete structure planning for bridges, SNI 03-2833-200X concerning earthquake resistance planning standards for bridges. The data used are drawing data and technical specifications used on the bridge, then the data is verified against planning consultants, project implementers, and observations at the location. The results of the analysis stated that the bridge abutment was declared safe from soil thrust and other forces, but did not have a good safety factor against shear forces. Landslides that occur can be resisted by the bridge abutments. This research is expected to be followed up by policymakers to repair bridges so that they are resistant to maximum shear forces, and provide safety signs from landslides to relieve public anxiety when crossing bridges, as well as provide reinforcement for the cliffs around the bridge.

The coronavirus disease 2019 (COVID-19) pandemic affected the homeless serving sector in significant ways, including impacts on service users and service providers. In this qualitative case study from Ottawa, Canada, we conducted 28 semi-structured interviews with service providers and key informants from the homeless serving sector to learn more about responses to the pandemic. We argue that, as it is currently designed, the homeless serving sector had limited opportunity to respond to the combined crises in housing, overdose, and COVID-19 with a transformative agenda. The article draws on Dej’s (2020) concept of the homelessness industrial complex, which argues that current systems manage and sustain rather than end homelessness. And we use Lipsky’s (1969; 1980) notion of street-level bureaucracy to explore the role of service providers as they translated shifting public health guidelines into action on the ground within contexts of ambiguity and constraint.  Service providers were tasked with keeping people safe from COVID-19 while managing broader social issues such as homelessness, food insecurity, mental health challenges, and an increasingly poisoned illicit drug supply. They described challenges such as narrowly directed funding and short-term and temporary solutions to homelessness. Staff faced significant occupational stress and burnout within demoralizing contexts (Kerman & Kidd, 2021; Kerman et al., 2022). Despite new partnerships and innovative approaches that emerged, responses to the pandemic in Ottawa were shaped by the homelessness industrial complex and did not significantly contribute to ending homelessness. Even so, public health measures were able to disrupt business as usual in the sector, sparking the question: what might be possible if homelessness comes to be understood as a public health crisis?

The purpose of this study was to assess the usage patterns of credit/debit cards across various demographic characteristics and to check their association with factors like card usage preferences, financial conditions, budget control, and money shortage. A close-ended questionnaire was used to record demographic information and responses to assess the comparative use of debit/credit cards in urban and rural areas of Lahore and Kasur. The estimated sample size was 225 consumers. After cleaning of data, the final sample analyzed consisted of 200 subjects. The empirical analysis was done through SPSS. The result shows that gender, occupation, area, and income play a significant role in the different usage patterns of credit/debit cards at the time of purchase.
Postmodernist Paradoxical Expression and Originality in Philip Roth’s “Deception”
Authors: SHARMA Dr. SHIVANI , SHARMA Dr. SONIA
Published: August 2022

The works of Philip Roth are no doubt outstanding and brilliant examples of denial of traditional and established Judaism. Just like the non-Jewish contemporaries as well as the predecessors, the Jewish writers in the last half of the twentieth century have contributed a great arrangement to the secularization of Jewish and American life. His novels present the enormity of the American Jewish trouble in relation to Israel and Arab conflict over the Promised Land. The works of Roth mark a new current in Jewish American fiction. Deception is an admirable and penetrative work of self-representation. These works exceeds the ordinary levels of living and touches the real meaning of postmodernist paradoxical existence. They also contribute to the postmodernist beliefs of chaotic, disordered relationships and confused requirements of the human self.

Carbon Capture Potential in Waste Modified Soils: A Review
Authors: A.Y. Iorliam , A.W. Opukumo , B. Anum
Published: August 2022

Carbonation of lime modified soil could capture carbon dioxide (CO_2) alongside strength improvement for road pavement materials. Due to large amounts of 〖CO〗_2 emissions and increasing cost of primary soil stabilizers such as lime and cement, the use of lime-based wastes have been encouraged. This paper reviews waste materials based on separate potential for 〖CO〗_2 capture and strength improvement of soils. Such wastes include cement kiln dust (CKD), saw dust ash (SDA), steel slag, basic oxygen steel (BOS) slag, ground granulated blast furnace slag (GGBS), coal fly ash (CFA) and cattle bone powder (CBP). Based on separated considerations of 〖CO〗_2 capture and strength improvement, CKD, SDA, BOS and GGBS have shown to have both high 〖CO〗_2 capture and strength improvement potential for weak soil. Future laboratory studies on lime-based waste (such as CKD and SDA) treated soil for combined 〖CO〗_2 capture and strength improvement need to be conducted.
A new metaheuristic approach for the meat routing problem by considering heterogeneous fleet with time windows
Authors: Riaño Hernando Barreto , Escobar John Willmer , Clavijo-Buritica Nicolas
Published: August 2022

Guided by a real case, this paper efficiently proposes a new metaheuristic algorithm based on Simulated Annealing to solve the Heterogeneous Vehicle Routing Problem with Time Windows to deliver fresh meat in urban environments. Our proposal generates an initial feasible solution using a hybrid heuristic based on the well-known Travelling Salesman Problem (TSP) solution and, subsequently, refining it through a Simulated Annealing (SA). We have tested the efficiency of the proposed approach in a company case study related to the planning of the transportation of a regional distribution center meat company to customers within the urban and rural perimeter of Bogotá, Colombia. The main goal is to reach a service level of 97% while reducing operational costs and several routes (used vehicles). The results show that the proposed approach finds better routes than the current ones regarding costs and service level within short computing times. The proposed scheme promises to solve the refrigerated vehicle routing problem.
A model for location-assortment problem in a competitive environmen

This paper considers simultaneously two areas of facility location and assortment planning in a competitive environment. In fact, a chain store that has competitors in the market locates a new facility. As there are different products in the market that can substitute with each other, it is intended to determine the best product assortment as well. An integer nonlinear programming problem is proposed to model the mentioned subject. For solving the model, the problem is reformulated as a mixed integer linear programming one. Therefore, a MIP solver software can be used for solving the small- and medium-size problems. For large-scale problems, a firefly algorithm is designed for obtaining a satisfactory solution. By using the proposed model, it is numerically shown that, in addition to the optimal location, it is also necessary to determine simultaneously the best product assortment for the new store. Actually, comparison results reveal that the location significantly affects the assortment scenarios for the new store. In other words, the selection of new store locations may lead to loss of large profit if the assortment planning is neglected.
More effective heuristics for a two-machine no-wait flowshop to minimize maximum lateness
Authors: Aydilek Harun , Aydilek Asiye , Allahverdi Muberra , Allahverdi Ali
Published: August 2022

We address a manufacturing environment with the no-wait constraint which is common in industries such as metal, plastic, and semiconductor. Setup times are modelled as uncertain with the objective of minimizing maximum lateness which is an important performance measure for customer satisfaction. This problem has been addressed in scheduling literature for the two-machine no-wait flowshop where dominance relations were presented. Recently, another dominance relation was presented and shown to be about 90% more efficient than the earlier ones. In the current paper, we propose two new dominance relations, which are less restrictive than the earlier ones in the literature. The new dominance relations are shown to be 140% more efficient than the most recent one in the literature. As the level of uncertainty increases, the newly proposed dominance relation performs better, which is another strength of the newly proposed dominance relation. Moreover, we also propose constructive heuristics and show that the best of the newly proposed heuristics is 95% more efficient than the existing one in the literature under the same CPU time.
Two-stage stochastic programming for the inventory routing problem with stochastic demands in fuel delivery
Authors: Li Zhenping , Jiao Pengbo
Published: August 2022

The inventory routing problem (IRP) arises in the joint practices of vendor-managed inventory (VMI) and vehicle routing problem (VRP), aiming to simultaneously optimize the distribution, inventory and vehicle routes. This paper studies the multi-vehicle multi-compartment inventory routing problem with stochastic demands (MCIRPSD) in the context of fuel delivery. The problem with maximum-to-level (ML) replenishment policy is modeled as a two-stage stochastic programming model with the purpose of minimizing the total cost, in which the inventory management and routing decisions are made in the first stage while the corresponding resource actions are implemented in the second stage. An acceleration strategy is incorporated into the exact single-cut Benders decomposition algorithm and its multi-cut version respectively to solve the MCIRPSD on the small instances. Two-phase heuristic approaches based on the single-cut decomposition algorithm and its multi-cut version are developed to deal with the MCIRPSD on the medium and large-scale instances. Comparing the performance of the proposed algorithms with the Gurobi solver within limited time, the average objective value obtained by the proposed algorithm has decreased more than 7.30% for the medium and large instances, which demonstrates the effectiveness of our algorithms. The impacts of the instance features on the results are further analyzed, and some managerial insights are concluded for the manager.
