The South Carolina Water Monitoring Portal - A Hub for South Carolina Water Quality Monitoring Data
Authors: Williamson Duncan , Levine Norman , Saari Brooke , Knapp Landon
Published: June 2024

The South Carolina (SC) Water Monitoring Portal is an ArcGIS-based, geospatial application that incorporates water quality data from a variety of sources and projects them onto an interactive map. This application will provide those interested in accessing and retrieving South Carolina water quality data with a free and easyto- use tool that allows for spatial visualization, interaction with, and direct download of data. At the time of this publication, the application accesses roughly four million water quality data records collected by seventeen different organizations. To allow users to seamlessly find and access the data they need, filters are available to query the data to match the user's needs. Once users find the data applicable to them, they can download and export it into various formats. The application also allows groups and organizations to indirectly upload their own water quality data to have it incorporated into the application. With these capabilities in a spatial format, this application has the potential to provide many benefits. For example, in academia it could be utilized in both classroom and research settings, and regulatory agencies could use this application to communicate water quality from a spatial viewpoint, potentially fostering a better understanding of water quality to stakeholders. The management and protection of our state’s waters are difficult to achieve when the data pertaining to water quality isn’t easily accessible or available in a user-friendly format. The SC Water Monitoring Portal has the potential to aid in the protection and management of our state’s waters as it makes water quality data more accessible and the retrieval of data more user-friendly. The SC Water Monitoring Portal is hosted on the South Carolina (SC) Sea Grant Consortium and the College of Charleston’s Lowcountry Hazards Center websites, making it available to anyone interested in water quality data in the State of South Carolina (available online: www.scseagrant.org/SCWMP).
Utilizing Watershed-Based Planning as a Tool to Protect Source Water: A Case Study from the Lower Caw Caw Swamp
Authors: Ellis Kathryn , Carbone Gregory
Published: June 2024

A watershed-based plan (WBP) is an example of a management tool that addresses nonpoint sources of pollution that affect surface water quality. We apply a simple spreadsheet tool to the Lower Caw Caw Swamp watershed in Orangeburg, South Carolina, to quantify the impact of modest management practices on water quality, and to examine how climate and land-use change could affect water quality in future decades. Three separate climate and land use scenarios are used to measure annual pollutant loads in the basin. Our analysis shows that E. coli loads in current conditions are largely attributed to anthropogenic sources of bacteria and have the potential to be reduced by about 15% with the implementation of structural stormwater best management practices (such as stormwater ponds and bioretention) and non-structural strategies (programmatic changes such as rooftop disconnection in residential areas and improving on-site sewage disposal systems). Modeled E. coli loads in future scenarios were almost twice the current loads as a result of a warmer climate and greater volumes of stormwater runoff generated by additional impervious surfaces and increased annual precipitation. These findings are consistent with others investigating water quality using future climate and land-use scenarios. We demonstrate that a simple watershed model can provide the basis for a watershed-based plan (WBP) to address nonpoint sources of pollution that affect surface water quality. This specific WBP analysis will be used to make recommendations to protect the City of Orangeburg’s source of drinking water along the North Fork of the Edisto River.
Identifying Barriers Preventing Stormwater Pond Buffer Implementation in Coastal South Carolina
Authors: Cannon Sean , Proschaska Abigail , Stewart Kendra , Callahan Timothy , Nowlin Matthew
Published: June 2024

Buffer zones are ecotones between upland areas and adjacent water bodies. They often consist of plant communities that stabilize shorelines, act as barriers reducing transport of fertilizer and lawn debris into water bodies, uptake nutrients and heavy metals, and provide habitat for wildlife. Few regulations exist that require vegetated buffers around stormwater ponds, and their widespread implementation has not occurred around ponds in coastal South Carolina. This lack of regulation on buffer requirements has potentially reduced the effectiveness of stormwater ponds and highlights the need to identify barriers preventing residents from implementing vegetated buffers. To investigate the barriers preventing the installation or support for stormwater buffer zones in coastal communities, an electronic survey was sent by e-mail through the South Carolina Department of Natural Resources and Ashley Cooper Stormwater Education Consortium listservs. Of the 646 respondents, 382 met the study criteria and identified owning a property with a pond or living in a neighborhood with one. Respondents were asked questions to determine their knowledge and perceptions of vegetated buffers, as well as their level of communication with landscape professionals. Results from this research indicate that residents are aware of the benefits vegetated buffer zones provide and prefer ponds with buffer zones over ponds with no buffer zones. This study reveals the following potential barriers preventing stormwater pond vegetated buffer zones: 1) limited knowledge of the costs associated with installation of vegetated buffer zones, 2) inadequate communication between residents and landscape professionals who maintain ponds, 3) respondents perceived lack of control over pond-related decisions, and 4) social norms within neighborhoods such as grass sod standards and an aversion to non-manicured vegetation. These findings can be used by stormwater professionals to help increase adoption of stormwater pond best management practices (BMPs) and improve water quality protection in South Carolina.

Authors:   ,   Cork Institute of Technology, Norris Eva
Published: June 2024

Carbon monoxide is a major trace gas pollutant with road traffic being responsible for most emissions. Work has been done on the development of a carbon monoxide sensor, which is potentially capable of measuring the gas in vehicle exhaust emissions. This is based on tunable diode laser absorption spectroscopy The device must distinguish carbon monoxide from other gas species and from particulate matter. The device should also operate with a response time of the order of one second, have the potential for portability and a capacity for remote operation. Experimental work presented compares and contrasts the characteristics of the free-running diode laser and the external cavity diode laser. The suitability of the external cavity diode laser as a carbon monoxide sensor is discussed. Two experimental methods used to evaluate the sensitivity of the device are described along with possible device improvements based on experimental results. The device’s potential for use as a portable sensor has been demonstrated by using low voltage DC components. Control software for the portable DC components has been written using LabVIEW programming language and the program functionality is fully described. The feasibility of using the sensor as a portable device for measurement of carbon monoxide in vehicle exhaust or for remote operation to measure stack emissions has been also been demonstrated by using fibre optic technology. The operation of a prototype carbon monoxide sensor developed by collaborative partners is discussed. Experimental data showing absorption due to the presence of carbon monoxide using equipment supplied by collaborative partners is also presented.

Authors:   ,   Cork Institute of Technology, Foley Grainne
Published: June 2024

The continuing evolution of wireless networks and services has increased the complexity and diversity of wireless networks and devices, placing significant emphasis on the need for flexible device configuration management. Widely varying wireless technologies currently operate independently worldwide, making global wireless network access for the mobile user confusing and unwieldy. New technologies, network access methodologies and improved services further obscure the evolving environment. The focus of effort for this thesis is the development of a system to automate the distribution and management of software and hardware configurations that enable different levels of wireless device reconfiguration. The scope of investigation will address the feasibility and development of techniques to centrally store and manage software and hardware configurations, automate the distribution of configurations to wireless devices Over-The-Air and provide mechanisms to receive and install those configurations onto the wireless device. The constraints imposed by operation in the wireless telecommunications domain are dealt with throughout the thesis. They include the diversity of communications networks, the heterogeneity of wireless device and capabilities, and the complexity of distributing the correct configuration to match device constraints.
Thermal Assessment Of Silicon-based Composite Materials Used In Photovoltaics
Authors:   ,   Cork Institute of Technology, Bataglannis Pavlos
Published: June 2024

"Photovoltaics are devices that convert sunlight directly to electricity. It is well established that the conversion efficiency of mono and poly-crystalline silicon-based photovoltaic modules is inversely related to their temperature. Substantial improvements in operational performance can thus be achieved if the thermal energy accumulating in the material can be effectively dissipated. Accurate modelling of modules would allow possible methods of thermal dissipation to be evaluated, and as a crucial component of the model, the thermal properties of the constituent materials of PV modules needed to be known. Special consideration needed to be given to the interfaces between dissimilar materials and to the interconnections. In this project the interface thermal resistances that exist between consecutive layers in a PV were fully determined. Pre-modelling took place to verify the existence and the significance of these thermal resistances. The validity of the model was proven experimentally by quantifying the interface resistances. They sum to a total of 3.19 C/W, which is equivalent to 23.8 /o of the total thermal resistances of the PV module. By including the results from the experimentation to the model, it was found that it is giving a representative picture of the photovoltaic thermal behaviour. Further experimentation took place by testing a PV module under simulated lighting conditions. These results are within an error range of 25%. Finally suggestions for further work and improvement of the model and the experimental results are given."
Design And Analysis Of Radio Frequency Deployment Algorithms For Gsm
Authors:   ,   Cork Institute of Technology, Pérez-Carbonell Monica
Published: June 2024

"Due to the growth of the subscriber base and the introduction of new services, mobile communications networks’ demand for wireless resources is increasing. This has resulted in an increasing need to change the frequency allocation of a network in order to adapt the cellular network to new frequency demands. Currently, a planning tool generates a new frequency plan, which is. then deployed to cell sites. The deployment should ideally be carried out with minimum disruption to network operation, which makes this deployment process a critical undertaking as any errors during or after the deployment can leave the network with poor or no service. Today, two methods are used to carry out this deployment. Binary download, which requires to shut down parts of the cellular system in order to download the frequency database, and sequencing deployment, where only the cell being modified will be shut down. To shut down a large part of the network is becoming more and more undesirable as operators require 99.999% up- time and users expect service availability around the clock, in particular for emergency related services. On the other hand, sequential deployment reduces this disruption but deploys the frequency plan not in a structured fashion but rather randomly. This work presents two different cell sequencing schemes, a sequential scheme and a parallel scheme, for on-line frequency deployment which solve the deployment problem for minimum disruption, in conjunction with a protocol that will control the transition between plans. Genetic Algorithms have been used as a stochastic optimisation technique to obtain the optimum cell sequence for deployment. The effectiveness of the proposed schemes is demonstrated through extensive computer simulation and results are compared with existing techniques."
Robust Generalised Predictive Control - An Optimal Design For Uncertain Systems
Authors:   ,   Cork Institute of Technology, O'Mahony Thomas
Published: June 2024

"One of the more popular model predictive control approaches, of late, is the generalised predictive controller (GPC). It has received widespread dissemination in academia and numerous successful applications in industry testify to its usefulness. Its popularity partly stems from its superiority over its predecessors, its simplicity and its control acumen. However, since GPC is based on a mathematical model of the process, significant deterioration in performance or even closed-loop instability may arise due to the inevitable discrepancies that arise between the model and the true system. To ensure that the loop stability is not compromised and an adequate level of performance is maintained the control law must be robust with regard to the plant-model mismatch. This may be achieved by manipulating a specific tuning parameter, the T-polynomial. However, the selection of this polynomial is not trivial as its effect is nonmonotonic. Furthermore, in practice T must be chosen to achieve a realistic trade-off between robustness and disturbance rejection performance. Despite this recognition, few of the existing tuning rules address this compromise and no systematic design exists. The primary contribution of this thesis is the development of a systematic tuning technique for the GPC such that an optimal trade-off between robustness and disturbance rejection is achieved. In this context optimal implies that the design should be just sufficiently robust to cater for the existing model uncertainty, in which case the disturbance rejection performance can be optimised. This design was achieved by minimising, with respect to T, an identical cost function as that employed in //«, control. PerfoiTnance was incorporated by including an additional criterion, the integral of error of the load disturbance response, into the optimisation. This problem formulation does not lend itself to an analytic solution and therefore a numerical technique, known as genetic algorithms, was applied. Based on the success of this design an auto-tuning tool for the GPC was developed. With this tool the servo performance is dictated by a user-specified nominal closed-loop transfer function while the regulator performance is dictated, as before, by the trade-off between robustness and disturbance rejection. This considerably simplifies the commissioning process. The usefulness of this tool is demonstrated by simulations in Chapter 4 and by real-time experiments in Chapter 5. In both cases the results are compared with previously published tuning techniques. The excellent results obtained support the belief that the advocated design is of practical significance and is the principal contribution of this thesis."

Misoprostol-induced seizures following self-abortion: a rare, but repeated occurrence
Authors: Purushotmanan Darshelaan
Published: June 2024

Misoprostol is a synthetic prostaglandin E1 (PGE) analogue used for medical termination of pregnancy, managing miscarriage, inducing labour, cervical ripening, and treating postpartum haemorrhage. Generally, it is safe and well-tolerated, with dose-dependent adverse effects such as nausea, vomiting, diarrhoea, abdominal pain, fever, and headache that usually resolve within a few days. However, seizures are a rare complication, occurring primarily in patients with a history of epilepsy or a predisposition to seizures and is associated with high doses and rapid administration. This case report highlights the repercussions of a misoprostol overdose used for pregnancy termination, leading to seizures induced by hyperthermia. The first patient required temporary invasive ventilation and resuscitation but recovered, whereas the second patient receiving a lower dose, exhibited milder symptoms. Both patients received psychosocial counselling prior to discharge.

The introduction of the automation and management principles for pharmacists’ activities using information systems is an effective way to increase profi ts and strengthen pharmacy profi tability. Companies use machine learning algorithms to adjust their strategy, study customer reviews about their organization through feedback analysis, and improve the company’s image. However, a signifi cant amount of pharmacists’ time and effort goes into the manual processing of incoming reviews. The article proposes automating the processing using the naive Bayes classifi er algorithm, which is implemented in Python. To train the classifi er, the authors created their own corpus of labeled review texts with two categories, with the total number of reviews being about 500. A parser written in Python was used to search for reviews. The following steps were taken during the preliminary processing of the reviews’ text: lemmatization, elimination of punctuation, the text’s letter conversion to lower case, tokenization, stop words removal, and text vectorization using the bag-of-words model. According to the numerical experiments carried out, the classifi er’s highest accuracy was achieved with an 80/20 ratio of training and test samples that did not include stop words. When using a classifi er, analyzing 100 reviews takes 8 times less time than manual reading. The classifi er itself can be presented as a separate application or as a module within an information system. Thus, the increasing number of positive reviews is an indicator of the company’s effi cient performance as well as the number of satisfi ed customers. The growth of its image will strengthen customers’ loyalty to the company, resulting in greater sales.

The article examines the social and economic development of territorial entities. The authors focus on the metropolitan cities of Russia, i.e., the administrative centers of the entities of the Russian Federation. The article examines the existing economic and legal literature on the problems and prospects of the social and economic development of cities. The existing limitations in the application of certain assessment methods regarding the territorial aspect are outlined. The authors have developed a methodology for multi-criteria assessment of the social and economic development level (SED index) of cities based on the assessment of key components of the social and economic development of metropolitan cities in the Russian Federation. The methodology was tested based on municipal statistics data from 83 metropolitan cities in the Russian Federation. The study covered the period from 2019 to 2021. The findings were assessed by comparing cities ‒ objects of the study, grouped by population size. The analysis demonstrated differentiation in the level of development of metropolitan cities, with the highest dispersion of values observed in the group of big cities with populations ranging from 250 thousand to one million people. Furthermore, the study found the general downward trend in the dynamics of the level of social and economic development of metropolitan cities in the Russian Federation over the studied period. The proposed methodology can be used to conduct studies of the social and economic development of territorial entities, monitor the level of social and economic development of cities, and make effective management decisions to reduce the excessive distance between city development levels.

En este trabajo reconstruimos los envíos de remesas desde las tesorerías regionales que componían la Real Hacienda del Virreinato del Río de la Plata hacia la caja de Buenos Aires entre 1780 y 1800. Sobre la base de los libros mayores de contabilidad de la caja de Buenos Aires, estimamos los volúmenes de recursos que las cajas del interior rioplatense enviaron a la administración de hacienda de la capital. En una comparación con la evolución de los fondos del situado potosino (principal ingreso de la tesorería principal del Virreinato) buscamos evaluar la relevancia que los recursos aportados por otras jurisdicciones tuvieron en los ingresos de la caja de Buenos Aires. Consideramos la reconstrucción de estos valores como elemento fundamental para poder elaborar indicadores de presión fiscal durante las últimas décadas del siglo XVIII que logren diferenciar/identificar las cargas de las múltiples jurisdicciones fiscales que componían el sistema de la hacienda colonial (municipal, regional, corporativo, virreinal). Las principales fuentes utilizadas se componen de libros de contabilidad (mayores) de la caja de Buenos Aires, de la caja de Santa Fe, Caja de Mendoza y libros manuales de arbitrios de Santa Fe (Archivo General de la Nación).

This study aims to determine the effectiveness of various filter materials in RAS such as synthetic materials and organic materials and there an impact on plasma cortisol, osmotic performance rate, growth rate and survival rate of Channa marulioides. The cultivation process in the RAS system is carried out for 100 days with 50 individuals in each different treatment, namely T1: Synthetic filter; T2: Organic filter; T3: Mixture of synthetic and organic filter; Control: No Filter and RAS. Measurements of plasma cortisol and osmotic performance levels were carried out at the beginning and end of cultivation which had an impact on growth and survival rates. The results of the study showed a decrease in cortisol levels (ng/ml), namely: T1: 9.24, T2: 9.66, T3: 10.37 which showed that there was no significant difference in each treatment (P> 0.05) but in T1, T2, and T3 were significantly different with control treatment: 1.32 (P<0.05). The same trend occurred when observing the level of osmotic performance with the highest decrease in T3 on 6 scales; T2 on a scale of 5.5; T1 has 5 scales, and Control has 3 scales. Reducing the level of cortisol and osmotic performance hormones with the RAS system can increase energy efficiency by reducing stress levels, and osmotic performance so that it can be optimized for growth and survival in adaptation.

Los resultados indican que los “bosques aleatorios” demostraron la mayor precisión en la predicción de cambios de precios, seguidos por K-Nearest Neighbors o KNN (algoritmo de k vecinos más próximos) y la regresión logística. Se identificaron factores significativos que afectan los precios de adquisición, como el tipo de medicamento y la duración de la estrategia de adquisición. Además, el estudio profundiza en las consideraciones presupuestarias, evaluando las implicaciones financieras de estas fluctuaciones de precios. Estos hallazgos destacan la efectividad de iniciativas como los enfoques de adquisición consolidada y la integración de medicamentos más nuevos y rentables en los protocolos de tratamiento, lo que conduce a ahorros significativos y mejor acceso para las personas que viven con VIH/sida. Es importante destacar que este artículo se centra en analizar un esquema específico de adquisición de medicamentos antirretrovirales. Los estudios futuros ampliarán este análisis para abarcar un espectro más amplio de esquemas de adquisición de medicamentos, proporcionando así una comprensión más completa de la dinámica de fijación de precios y sus implicaciones para la salud pública. Además, la investigación en curso perfeccionará la metodología e integrará fuentes de datos adicionales para mejorar la precisión y profundidad del análisis.

Nowadays, people prioritize security above all else, making it a more important concern in their lives. The proposed work aims to replicate the extensive literature research on OTP-based door locks, which are crucial for residential, commercial, and auto security because of ever increasing risk of theft. The existing methods include various kinds of door lock security systems, such as traditional security systems that transmit signals through alarms. Some door lock security systems are based on GSM, GPS, and biometrics like face recognition, iris scanning, RFID, smart cards, and passwords. Every system has benefits and drawbacks of its own. Overcoming the limitations of authentication mechanisms like mechanical and digital door locks is the reason why access control systems based on OTP are preferred. The user does not require the administrator’s help to access the door if they are familiar with the proposed method and have the registered mobile number and OTP. The OTP is generated and sent to user’s mobile number whenever the user accesses the door.

Public Use, Public Choice, and the Urban Growth Machine: Competing Political Economies of Takings Law
Authors: Lyons Daniel
Published: June 2024

The Kelo decision has unleashed a tidal wave of legislative reforms ostensibly seeking to control eminent domain abuse. But as a policy matter, it is impossible to determine what limits should be placed upon local government without understanding how cities grow and develop, and how local governments make decisions to shape the communities over which they preside. This Article examines takings through two very different models of urban political economy: public choice theory and the quasi-Marxist Urban Growth Machine model. These models approach takings from diametrically opposite perspectives, and offer differing perspectives at the margin regarding proper and improper condemnations. But surprisingly, both models stand united in opposition to economic development takings and both view skeptically the current wave of eminent domain reform. By discussing why each model comes to this conclusion, this Article sheds additional light upon the substantive limits that legislatures should place upon eminent domain authority and procedural reforms that would help assure proper exercises of that power within this circumscribed scope. The Article also recommends greater cooperation between legislatures and judiciaries to develop these broad standards and to assure that condemnation authorities adhere to them in individual cases.
Duty of Fair Representation Jurisprudential Reform: The Need to Adjudicate Disputes in Internal Union Review Tribunals and the Forgotten Remedy of Re-Arbitration
Authors: Rubinstein Mitchell
Published: June 2024

One of the best kept secrets in American labor law is that duty of fair representation jurisprudence simply does not work. It does not work for plaintiff union members because they must satisfy a close-to-impossible burden of proof and have a short statute of limitations window in which to assert their claim. It does not work for defendant unions because they are often forced to file pointless grievances in order to avoid the cost of litigation. It does not work for defendant employers because they are often brought into these lawsuits because they have the "deep pockets."

This Article makes two proposals to reform duty of fair representation jurisprudence. First, this Article posits that putative plaintiffs should be required to have their claims adjudicated before internal union review tribunals as opposed to courts. This internal tribunal system, if procedurally and substantively fair, would provide unions with a complete defense to duty of fair representation claims. This would move most duty of fair representation disputes from the ex-post stage (after a court dispute has arisen) to the ex-ante stage (before a court dispute has arisen) and reduce unnecessary litigation. Second, this Article argues that the current system needs to be "tweaked" to return to the original Vaca v. Sipes, 386 U.S. 171 (1967), intent of utilizing re-arbitration as a remedy, as distinguished from money damages, when a breach of the duty of fair representation is found.
Improving robust indicators of sliding modes based on decomposition
Authors:   Rustamov G.A.
Published: June 2024

The sliding mode control system based on the decomposition principle is divided into two parts: a sliding mode generation subsystem and a robust subsystem with large gain factor. Increasing the gain factor without loss of stability makes it possible to suppress the total uncertainty of the general form to an arbitrarily small value. This feature allows the system to move along a given trajectory without self-tuning of the sliding mode. Qualitative analysis on Simulink showed the effectiveness of the proposed approach.

Keywords

Model-based approach to formalizing a production system architecture
Authors:   Vanroye N.K. Vlasov A.I. SHahnov V.A.
Published: June 2024

An approach to developing a set of related system models that forms the boundaries of the subject area, a hierarchical decomposition of the target system itself and its formalized description, called Model-based System Engineering, is considered. This approach is one of the basic systems engineering tools in the system modeling practice of complex systems. The results associated with the application of a model-based approach in complex supply chain planning systems in the electronics industry are presented. A comparative analysis of modeling languages for systems (SysML), web ontology (OWL) and the visual language of the BPMN method was carried out from the perspective of tools and a model-oriented approach. Recommendations are given on the use of tools for developing visual system models when modeling the order management process within the framework of supply chain control in the electronic equipment production.

Research of the influence of element deformation and manufacturing errors of planetary gears on the load distribution among satellites
Authors:   Plehanov F.I. Molchanov S.M. Suntsov A.S.
Published: June 2024

A technologically advanced multi-satellite design of a toothed planetary gear is studied, in which the carrier is made in the form of two cheeks, which are connected to each other by the axes of the satellites, which act as jumpers. The problem of the stress-strain state of mating elements is solved using differential equations of the curved axis of the satellite, represented by a beam on an elastic foundation. The distribution of the load across the satellites is determined taking into account the deformation of the gear segments and the non-adherence of the gear teeth caused by errors in its manufacture.
Keywords:planetary gear, non-rigid carrier, compliance of segments, load distribution
