Hybrid Flow Shop Scheduling of Automotive Parts
Authors: Supeekit Tuangyot , Somboonwiwat Tuanjai
Published: November 2023

Flow shop scheduling problem is a type of scheduling dealing with sequencing jobs on a set of machines in compliance with predetermined processing orders. Each production stage to be scheduled in typical flow shop scheduling contains only one machine. However, in automotive part industry, many parts are produced in sequential flow shop containing more than one machines in each production stage. This circumstance cannot apply the existing method of flow shop scheduling. The objective of this research is to schedule the production process of automotive parts. The feature production is hybrid flow shop which consists of two-stages. In each stage, there are several manufacturing machines and each machine can produce more than one product. Thus, production scheduling is a complex problem. This paper, therefore, develops mathematical model to solve the hybrid flow shop production scheduling under different constraints of each machine. The setup time and production time of each machine can be different for each part. The solution for the experimental data sets from an automotive part manufacturer reveals that the process time can be reduced by 34.29%.

Failure-Handling Strategies for Mobile Robots in Automated Warehouses
Authors: Lienert Thomas , Fottner Johannes
Published: November 2023

Automated warehouses operated by a fleet of robots not only offer great flexibility, as fleet size  can be adjusted easily to throughput requirements, they also provide higher redundancy compared to common solutions for automated storage and retrieval systems. In case a single robot fails, the remaining fleet of robots is able to continue working within the system, so that throughput is only slightly affected. However, adequate strategies are required for this scenario. In this contribution, we present four different approaches to cope with robot downtimes, which are based on the routing of the robots. These strategies are compared by performing a simulation study in which a robotic mobile fulfilment system is considered.
Simulating Dynamic Vehicle Routing Problems with Athos
Authors: Guckert Michael
Published: November 2023

Complex routing problems, such as vehicle routing problems with additional constraints, are both hard to solve and hard to express in a form that is accessible to the human expert and at the same time processible by a computer system that is supposed to produce a solution of suf�?cient quality. The formulation must be formal enough to avoid ambiguities and also comprehensible enough to be created, discussed and shared by domain experts. In this paper, we present the domain speci�?c language Athos in which complex routing problems can be expressed in a computationally independent, human-readable form. Athos is then transformed into code that can be run in an adequate target platform. Suitable methods for solving problems are available and applied to the given problem. We present a case study in which we use a genetic algorithm to solve instances of a vehicle routing problem with time windows and demonstrate the end to end process to produce a solution in the Athos environment. Moreover, we show how the Athos system goes beyond optimisation of static routes and can be used as a tool to simulate the impact of traf�?c and congestion on the tours. We call this extended problem a dynamic vehicle routing problem with time windows.

Hydrothermal Destruction and Defluorination of Trifluoroacetic Acid (TFA)
Authors: Austin Conrad , Purohit Anmol , Thomsen Cody , Pinkard Brian , Strathmann Timothy , Novosselov Igor
Published: November 2023

Per- and polyfluoroalkyl substances (PFAS) have received increased attention due to their environmental prevalence and threat to public health. Trifluoroacetic acid (TFA) is an ultra-short-chain PFAS and the simplest perfluorocarboxylic acid (PFCA). While the US EPA does not currently regulate TFA, its chemical similarity to other PFCAs and its simple molecular structure make it a suitable model compound for studying the destruction of PFAS. We show that hydrothermal processing in compressed liquid water degrades TFA at relatively mild conditions (T = 150 – 250 ˚C, P < 30 MPa), initially yielding gaseous products, such as CHF3 and CO2, that naturally aspirate from the solution. Alkali amendment (e.g., NaOH) promotes the mineralization of CHF3, yielding dissolved fluoride, formate, and dissolved carbonate species as final products. Fluorine and carbon balances are closed using Raman spectroscopy and fluoride ion selective electrode measurements for experiments performed at alkaline conditions, where gas yields are negligible. Qualitative FTIR gas analysis allows for establishing the degradation pathways; however, the F-balance could not be quantitatively closed for experiments without NaOH amendment. The kinetics of TFA degradation under hydrothermal conditions are measured, showing little to no dependency on NaOH concentration, indicating that the thermal decarboxylation is a rate-limiting step. A proposed TFA degradation mechanism motivates additional work to generalize the hydrothermal reaction pathways to other PFCAs.
Morphological Properties and Electrochemical Performance for Compressed Carbon-fiber Electrodes in Redox Flow Batteries
Authors: Liu Baichen , Bredmose Simonsen Søren , Hjelm Johan
Published: November 2023

Recognizing the urgent need for further cost reduction to drive deep penetration of redox flow batteries as grid-scale stationary energy storage systems in the global energy mix, it is critical to improve reactor performance to bring down the high capital cost. As one of the main contributors to the overall internal resistance, porous electrodes with properly designed microstructure and optimized physiochemical properties are preferable for boosting electrochemical and fluid dynamic performance. The present study aims to unveil the relationship between electrode morphology and electrochemical performance under varying electrode compression. Three representative, commercially available, carbon-fiber electrodes (i.e., paper, felt, and cloth) with distinct microstructures were selected here, and a comprehensive study was conducted to compare morphology, hydraulic permeability, mechanical behavior, electrochemical properties including decoupled kinetic and mass transfer resistances, and overall battery performance in a lab-scale vanadium redox flow battery at 0-50% compression ratios. The 3D electrode morphology was characterized through X-ray computed tomography and the extracted key microstructure parameters (e.g., surface area and tortuosity) were compared with corresponding electrochemically determined parameters. It was found that the cloth possessed a bimodal pore size distribution due to its distinct woven microstructure and that it was sensitive to the applied compression. The large pores formed at the intersections between fiber bundles collapsed under excessive compression, which greatly reduced the advantageous high permeability and low mass transfer resistances characteristic of the uncompressed cloth. The paper electrodes exhibited a strongly growing compression force accompanied by increased in-plane tortuosity and mass transfer resistance even at low compression (<20%). During battery operation, the cloth maintains a good balance between performance and pressure drop at moderate compression. The optimal trade-off between fluid dynamics and electrochemical performance occurred at the compression ratios of 30%, 20%, and 20% for the felt, paper, and cloth, respectively.
Far-red light-triggered cargo release from liposomes bound to a photosensitizer-cellulose nanofiber hydrogel
Authors: Lem Olga , Durandin Nikita , Laaksonen Timo , Efimov Alexander , Gangurde Puja , Keskinen Aleksi
Published: November 2023

Light-triggered release from liposomes has been extensively researched. In virtually all the cases the photosensitizer has been encapsulated in liposomes core or liposomal membrane. However, the light-triggered drug release system, where the photosensitizer is located outside of the liposomes has never been reported before. The central concept of our research revolves around the far-red light-induced release of cargo from liposomes embedded in anionic nanofibrillar cellulose (ANFC), wherein the photosensitizer resides in the hydrogel, outside of liposomes. Both the sensitizer and the liposomes bind strongly to the anionic cellulose nanofibers by simple mixing, making the system easy to fabricate. Upon light activation, this photosensitizer generates reactive oxygen species, which, in turn, induce the liposomal bilayer disruption, ultimately resulting in cargo release. The release mechanism is the generation of reactive oxygen species and the subsequent oxidation of unsaturated lipids in the liposomal membrane. We were able to achieve ca. 70 % release of model hydrophilic cargo molecule calcein with a relatively low dose of light (262 J/cm2) while employing straightforward fabrication techniques for the drug delivery system. Our system was remarkably responsive to the far-red light (730nm, 0.875 W/cm²), enabling deep tissue penetration. Therefore, this very promising novel cellulose-immobilized photosensitizer liposomal complex could be used as a controlled drug delivery system, which can have potential applications in externally activated coatings or implants.

Published: November 2023

Porous aluminosilicates are functional materials of paramount importance as Lewis acid catalysts in the synthetic industry, yet the participating aluminum species remain poorly studied. Herein, a series of model aluminosilicate networks containing [L–AlO3] (L = THF, Et3N, pyridine, triethylphosphine oxide (TEPO)) and [AlO4]– centers were prepared through non-hydrolytic sol-gel condensation reactions of the spherosilicate building block (Me3Sn)8Si8O20 with L–AlX3 (X = Cl, Me, Et) and [Me4N] [AlCl4] compounds in THF or toluene. The substoichiometric dosage of the Al precursors ensured complete condensation and uniform incorporation, with the bulky spherosilicate forcing a separation between neighboring aluminum centers. The materials were characterized by 1H, 13C, 27Al, 29Si, and 31P MAS NMR and FTIR spectroscopies, ICP-OES, gravimetry, and N2 adsorption porosimetry. The resulting aluminum centers were resolved by 27Al TQ/MAS NMR techniques and assigned based on their spectroscopic parameters obtained by peak fitting (δiso, CQ, η) and their correspondence to the values calculated on model structures by DFT methods. A clear correlation between the decrease in the symmetry of the Al centers and the increase of the observed CQ was established with values spanning from 4.4 MHz for distorted [AlO4]– to 15.1 MHz for [THF–AlO3]. Products containing exclusively [TEPO–AlO3] or [AlO4]– centers could be obtained (single-site materials). For L = THF, Et3N, and pyridine, [AlO4]– centers were formed together with the expected [L–AlO3] species, and a viable mechanism for the unexpected emergence of [AlO4]– was proposed.

Published: November 2023

Root canal treatment is a treatment sequence for the infected pulp of a tooth which is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion. During root canal treatment, it is possible that the gutta-percha cones, which are a permanent filling in the treatment, become contaminated. Before being placed in the root canal, it must be sterilized. Additionally, the gutta-percha sterilization process may lead to bacterial growth in the root canal. Thus, gutta-percha sterilization should take place at the same time as root canal cleaning. For this purpose, gutta-percha sterilization must be automated, instead of conventional disinfection methods. The primary objective of this study is to automate the gutta-percha sterilization operation and improve disinfection efficacy with a low turn-around time and high precision. As per the results obtained during the experiment, the turn-around time for sterilization takes 5-8 minutes with good disinfection efficacy in microbial testing and a precision of 92% for 57 cycles of testing.
Programmed railway gate regulator using ultrasonic sensors and arduino UNO
Authors: Vajja Parameshwar Rao
Published: November 2023

An automatic railway gate control system using an Arduino UNO and IR sensors is proposed in this study. The manually operated rail gates can be converted into automatic control of railway gates using different types of sensors. These are mostly needed where the track passes over a city, neighborhood, or redundant gateways of the passage regions. The gates are currently manually operated by gatekeepers according to the existing system, depending on signals obtained from the control centre. Accidents are most likely to occur in such cases, causing severe loss of human lives and property near rail crossing zones. The programmed railway gate regulator tracks the movement of the train and detects obstacles, thereby notifying the server motor to open or close the gate automatically. This study also suggests the effective use of real-time information on the train positions. The main objective of this study is to safeguard efficiency, quality, time management, public safety and automation.

Published: November 2023

Energy conservation is a key challenge for a sustainable lifestyle. However, it is often ignored because of a lack of knowledge and inability to predict the lifetime of electric or electronic equipment. Energy conservation is the most cost-effective strategy for coping with energy shortage. This study proposes the implementation of e-Life devices to solve this problem and promote public awareness. Electricity-intensive products have their own power specifications and lifespans; over time, the amount of power they use is greater than expected because of the effects of aging. The e-Life algorithm used in an Internet of Things (IoT)-enabled electronic device is integrated into any electrical load to monitor power usage and understand the product replacement time. It is proposed to be aware of the excessive power consumption of all-electric or electronic equipment.

Authors: Clifford Kawinga , Shaju G. M.
Published: November 2023

The impact of the installation of prepaid water meters on the performance of Lilongwe Waterboard, a water utility company in Malawi, was the main focus of this study. A survey was conducted among corporate consumers using prepaid water meters, and the data collected were analyzed using descriptive statistics. The results showed that prepaid water meters have improved the billing of corporate customers, with monthly bills decreasing significantly after the introduction of prepaid meters. However, customers still faced challenges such as inconsistent water supply, high installation costs, high operational costs, inability to purchase water due to poor network, and low water pressure. The study recommends that Lilongwe Waterboard should continue to improve its services to minimize customer complaints. Further research is needed to assess the impact of prepaid water meters in other locations. Due to its high cost and the service provider's inability to maximize revenue from the generated billing, the system has received a lot of criticism from customers. It is necessary to determine the billing patterns prior to and following the implementation of prepaid water meters and to assess the impact of those patterns on the operation of the Lilongwe Waterboard.
Corruption and its effects on the development of public sector management in Africa - A case study of ghana
Authors: William Bediako Danso
Published: November 2023

There is a growing perception that bribery and corruption are on the ascendant in Ghana and the rest of the African continent among the public sector. Many corrupt managers, top government officials, and public employees hide behind an institutional veil to rub states, countries, and organizations with huge sums of money for their selfish interests and personal gain. Over the years, servants in public services such as the Judiciary, the Police, Food and Drug Authority, Standards Authority, Immigration, and Customs Authority, like any other work environment in the public sector in Ghana and on the other continent, have been tagged with the reality of corruption and bribery. These corrupt practices within the public service in Ghana have really dented the reputation of many professions, including the judiciary and state security agencies. Corruption has worsened in state institutions, and this has had serious negative impacts on the development of the economy and its political dispensation. The overall aim of this research was to investigate the complex nature of corruption and its impacts on the development of public sector management in Ghana and other West African regions. The research began with a review of the literature on the complex nature of corruption and its impacts on the development of effective and efficient public management in Ghana. This was followed by case-bycase studies of two African countries (Ghana and Nigeria) linking it to their judicial administrations, police administrations, customs divisions, and food and drug authorities, among others. Primary data was also gathered from a field survey using interview questionnaires to unearth some of the challenges faced by Ghanaians in the fight against corruption. This study revealed that corruption in judicial settings, policing, the Food and Drug Authority, Immigration, and Customs Division in the countries stated in this case does not only involve giving or accepting bribes. It includes embezzlement, patronage, conflict of interest, theft, fraud, or insider dealing. This study will be of immense benefit to politicians and managers of law enforcement agencies.

Published: November 2023

Everyone is well aware of the wastage of water through tanks, which has always been a concern. In many cities and villages, water wastage has increased as people have not maintained their tanks properly. This paper is designed to monitor and control water levels in tanks, reservoirs, or other storage containers. The proposed system utilizes a combination of sensors, microcontrollers, and actuation mechanisms to provide real-time monitoring and control of water levels. This automated approach offers numerous benefits, including improved water conservation, reduced energy consumption, and enhanced convenience. For smaller tanks, solutions such as ball valves are applicable, which automatically stop the water flow once the tank is full. This is a simple and basic idea for smaller tanks. However, in many large tanks located in buildings, hotels, schools, etc., which require a significant amount of water storage, there is a need to prevent overflow. An electronic solution can be implemented to save water. When the tank is nearing full capacity, it will raise an alarm and stop the water pump. Conversely, it can also help fill the tank when it's empty using an electronic device. The Arduino Uno-based automatic water level indicator and controller is a practical and efficient solution for monitoring and controlling water levels in various applications. This system utilizes ultrasonic sensors to measure water levels by emitting sound waves and calculating the distance based on the echoes they receive after bouncing off obstacles in the water. The Arduino Uno-based automatic water level indicator and controller utilizing ultrasonic sensors is a practical and versatile solution for managing water levels efficiently. It offers accurate measurements, automation, cost-effectiveness, and adaptability for various applications, making it a valuable tool for water level monitoring and control.

The integration of education technology and innovation into the education sector is increasingly becoming a global imperative, with the potential to transform teaching and learning practices. In Malawi, like many other developing nations, the adoption, implementation, and effective utilization of education technology remain critical challenges. This case study focuses on Mpherembe (CDSS) in Malawi to provide a detailed assessment of the status of education technology adoption and its impact on teaching and learning. The need for educational technology has risen in many schools in Malawi, especially during the pandemic's arrival of COVID-19, cholera outbreaks, and Cyclone Freddy, bringing attention among teachers, students, and policymakers. The study was centered at Mpherembe CDSS, where a sample of 20 students and teachers was selected using a probability sampling technique. The data was collected using a questionnaire and analyzed using SPSS. The analyzed data was presented in the form of bar graphs. The study uncovered that there was a moderate extent of adoption, implementation, and effective utilization of educational technology in Malawi. Furthermore, the study revealed that there are several significant benefits of educational technology in Malawi. The main ones include reducing transportation and accommodation costs and accommodating both work and learning simultaneously. Despite the benefits, educational technology faces several challenges that hinder its adoption, implementation, and utilization in Malawi. These challenges include poor network infrastructure, high costs, and limited access to educational technology.

Trajetória, distância percorrida e deslocamento: formação de conceitos a partir do uso de brinquedos de dar corda
Authors: Cunha Alexander Montero , Siebeneichler Alisson Francisco Schneider , Pastorio Dioni Paulo , Roso Caetano Castro
Published: November 2023

Neste artigo analisamos as contribuições e os limites de uma atividade experimental para a compreensão dos conceitos de trajetória, distância percorrida e deslocamento. A atividade experimental foi desenvolvida no âmbito do Programa Residência Pedagógica por um estudante de licenciatura em Física em uma escola estadual localizada na cidade de Porto Alegre. Como fundamentação, dialogamos com as perspectivas teóricas de Perfil Epistemológico, Perfil Conceitual e a Abordagem Semiológica a fim de destacar variadas dimensões presentes no ensino dos referidos conceitos. A inserção de uma atividade prática pode ser uma estratégia de mobilização dos estudantes e de concretude para a aprendizagem de determinados conceitos científicos. Observamos, entretanto, que é preciso considerar as variadas dimensões conceituais envolvidas a fim de contribuir com uma compreensão mais ampla dos conceitos científicos, mesmo no ensino de trajetória, distância percorrida e deslocamento, que podem ser considerados conceitos simples ou básicos.
