The Benefits of Early Work Experience for School Dropouts: Evidence from a Field Experiment
Authors: Hervelin Jérémy , Villedieu Pierre 
Published: February 2024

Abstract
Employers do not necessarily view dropouts as completely lost causes, as they represent a heterogeneous group of young individuals actively seeking opportunities in the labor market. This raises the question of whether job-related work experience, especially in tight occupations, is sufficient to increase the employment opportunities of school dropouts in comparison with graduates. To answer this question, we conducted a correspondence study with 6,400 applications sent to real job offers and 8,200 unsolicited applications between January and December 2018. We found that dropouts have lower probabilities of being interviewed for job positions than graduates, but this gap is narrowed for dropouts who acquired work experience and even more when skill certification is associated. Furthermore, sending unsolicited applications close the interview rate gap in slack labor markets for dropouts with work experience.

Published: February 2024

This research focuses on the successful development of Agel Leaf Fiber (ALF)-Epoxy composites added with Carbon Active Powder (CAP) and printed using the Vacuum Pressure Infusion (VAPRI) method. Considering the importance of determining the mechanical properties of composites as raw materials for making fishing boats, this research aims to determine the use of Agel Leaf Fiber (ALF) in polymer matrix composites. The composite morphology was analyzed using Scanning Electron Microscopy (SEM) and ImageJ software. The mechanical properties evaluated included Tensile Strength, Flexural Strength, and Hardness. The composite was prepared by incorporating CAP in varying volumes of 0 %, 10 %, and 30 % with a fixed ALF percentage of 40 %. The results showed that the addition of CAP significantly increased the tensile strength to 128.51 MPa, with 0.068 % elongation, 1787.39 MPa modulus of elasticity, and a hardness value of 75.2 HD. Furthermore, the addition of 10 % carbon exhibited a remarkable improvement in flexural strength, reaching 238.51 MPa. This improvement could be attributed to reduced porosity, resulting in enhanced bonding between ALF-CAP-Epoxy components. The flexural strength of the composite with the highest CAP content experienced a significant increase of 238.51 MPa. Thus, Agel leaf fiber has the potential to be used as a reinforcing material in the manufacture of composites and is applied in the manufacture of environmentally friendly fishing boat bodies

Published: February 2024

Construction of new ships in Indonesia. In this case study, the construction of a 600 DWT Ro-Ro ferry. The 600 DWT Shipbuilding Project involves various risks that may affect the schedule and results. A risk assessment involving the quality control team, project lead, and production management is carried out to identify and quantify the level of risk and its consequences.
The results of this assessment assist in understanding and managing project risk, stress the importance of communication and coordination between teams, and enable better contingency planning and more effective project management. The FMEA calculation method is used to identify potential failure modes, determine the impact of each failure, and calculate a risk score based on the probability and effect of each failure. The Bayesian method updates the likelihood of failure based on new data that appears during the shipbuilding process. FMEA data is taken from the RPN (Risk Priority Number) at the Occurrence value, then weighted against the list of risks. Most risks are considered 'rare' in terms of likelihood and 'insignificant' in terms of consequence, indicating that despite potential obstacles, the impact on the project is expected to be minimal. However, several risks with 'minor' effects have been identified, highlighting the importance of effective risk planning and mitigation.
The integration of this method still needs to be improved, especially in the shipping industry. This method can be developed by making applications to control the procurement of materials at the beginning and during the construction and evaluation process at the end. The effort to make the ship construction timely according to the contract answers the shipbuilding challenges that often occur in developing countries

Published: February 2024

Emergency rooms are one of the most complex and vital areas of healthcare institutions, which have presented overcrowding, long waiting, and length of stay times, affecting the timeliness, responsiveness, and quality of service. This research aimed to design a detailed patient flow model to improve emergency room performance using the hierarchical timed colored Petri nets. Then, the model was simulated to evaluate scenarios considering tactical decisions such as physician staff planning, operational decisions such as adjusting work schedules, and strategic decisions such as increasing observation beds. The best scenario would reduce the average waiting times for triage II patients by 17.30 % and 47.57 %, and triage III by 33.49 % and 43.49 % for medical consultation in the office or the minor surgery room, respectively. In addition, the waiting time in observation and the rate of patients left without being seen by a physician would be reduced by 92.45 % and 74.67 %, respectively. These results improve the quality and timeliness of the service and avoid putting the patient's health and life at risk. The designed model included more attributes for patients concerning the place of medical care in the emergency room, the number of visits to the physician, and the physician who will care for the patient. Moreover, the simulation model includes observation beds as a limited resource blocking new patient admission. Finally, this model is a tool to support emergency room managers in making short, medium, and long-term decisions to address problems such as overcrowding, long waiting and length of stay times, and high rates of patients left without being seen by a physician

Actinide minor is a reactor waste with high toxicity and a long half-life. Minor actinides can be reduced by reusing them as fuel mixtures in reactors. This research uses PWR reactors with the primary fuel UN-PuN or Uranium Plutonium Nitride with a burning time of 5 years. The fuel consists of enriched Uranium, reactor-grade Plutonium from LWR waste, and minor actinides including Neptunium-237, Americium-241, and Curium-244. The purpose of this study was to find a design that is effective in reducing minor actinide waste. There are six designs or cases used in the addition of minor actinides. Each case has six minor actinide pins in each assembly. The addition of minor actinides is arranged in heterogeneous cores. The analysis was carried out by observing the values of k-eff, excess reactivity, and mass of minor actinides obtained from simulations using OpenMC code 0.13.2 and the ENDF/B-VIII library. The homogeneous core obtained an excess reactivity of 9.7 % with a percentage of plutonium of 8 %. The results of the homogeneous core are used as a reference for preparing a heterogeneous core. The heterogeneous core obtained an excess reactivity of 9.9 % with a percentage of plutonium F1: 5.5 %, F2: 8 %, and F3: 10.5 %. Np-237 can be reduced by 53 kg, and Am-241 can be reduced by 61 kg with minor actinide pins in case 1. Cm-244 can be reduced by 363 kilograms with minor actinide pins in case 6. Excess reactivity in the addition of Np-237 and Am-241 decreased to 5.3 %, while the accumulation of Cm-244 increased to 12.1 %.
A rheophysical study of the non-newtonian behavior of water flow in thin channels
Authors: Veliyev Fuad , Aslanova Aida 
Published: February 2024

The development of low-permeable hydrocarbon reservoirs is becoming an increasingly urgent task, and therefore, the study of the laws of fluid movement in subcapillary pores and microcracks is a crucial scientific and technical problem. The previous experimental studies revealed that a viscous liquid during flow in low-permeable reservoirs exhibits an anomalous non-Newtonian character, accompanied by a violation of the linearity of the filtration process, and, consequently, Darcy's law. It was also established that starting from a certain critical size of the opening of the crack, the flow of a Newtonian fluid (water, viscous oil) becomes non-Newtonian, with the manifestation of an initial pressure gradient and flow locking. In this research work, rheophysical aspects of the non-Newtonian behavior of water during flow in thin rectangular channels are considered experimentally. Using the microchannel model, it is established that the nonlinear rheological effect in the flow of water in micro-slits is mainly caused by the value of the electrokinetic potential of the system, by reducing of which it is possible to significantly weaken the non-Newtonian nature of the fluid. To regulate the electrokinetic potential of the fluid system, an antistatic additive was used, the optimal concentration of which was established experimentally. The optimal concentration is defined to be 0.006 %. Based on the Bingham model, the rheological parameters of water flow were estimated at different micro-slit clearances changed in the range of 10÷25 micrometers, in the absence and presence of an antistatic additive. It is also established that a reduction in the electrical potential of the fluid flow leads to a significant decrease in the yield shear stress during the flow of water in the microchannel
Comparision of both methods psi and curli: applied in solving multi-objective optimization problem of turning process
Authors: Trung Do Duc , Phuong Giang Nguyen Thi , Son Nguyen Hoai 
Published: February 2024

Solving a multi-objective optimization problem involves finding the best solution to simultaneously satisfy multiple predefined objectives. Currently, various mathematical methods are available for solving optimization problems in general, and multi-objective optimization in particular. The comparison of mathematical methods when addressing the same problem has been explored in numerous studies. In this study, let’s conduct a comparison of two multi-objective optimization methods: the PSI method and the CURLI method. These two methods were applied collectively to tackle a multi-objective optimization problem related to a turning process. Experimental data were borrowed from a previous study, and a total of sixteen experiments were conducted. Roughness average (Ra), Roundness Error (RE), Tool Wear (VB), and Material Removal Rate (MRR) were the four output parameters measured in each experiment. The objective of solving the multi-objective optimization problem was to identify an experiment among the sixteen existing experiments that simultaneously minimized the three parameters of Ra, RE, and VB while maximizing MRR. The optimal results determined using the PSI and CURLI methods were also compared with the optimal results obtained through other methods (COCOSO, MABAC, MAIRCA, EAMR and TOPSIS) in published documents. The comparison results indicate that the optimal experiment found using the CURLI method consistently matches that of other methods. In contrast, the optimal results obtained through the PSI method differ significantly from those obtained through other methods. The Spearman correlation ranking coefficient between CURLI and the five methods COCOSO, MABAC, MAIRCA, EAMR, and TOPSIS is very high, ranging from 0.9 to 1. In contrast, this coefficient is very small when comparing PSI with the aforementioned five methods, falling within the range of –0.6088 to –0.3706 in this case. Ultimately, this study concludes that the CURLI method is suiTable for solving the multi-objective optimization problem in the turning process, whereas the PSI method is deemed unsuitable

Published: February 2024

This research presented the utilization of Safety Transient Voltage Suppressors (STVS) in the track circuits of railway signaling systems, occurring during circuit switching due to changes in track occupancy conditions, resulting in damage and malfunction of the BR966F2 relay. The study employed Failure Modes and Effect Analysis (FMEA) combined with 1kV actual transient overvoltage testing featuring a waveform slope of 184/380 μs. Results revealed two transient voltage suppression levels encompassing Set A_(a,b), Set B_(a) and Set C_(a,b) as well as Set A//Set B//Set C and All Mode. These configurations achieved a clamping voltage of 41.6 V, categorized as Stage 1. Configurations like Set A_(c), Set B_(b,c) and Set C_(c) displayed increased series circuit behavior leading to a clamping voltage of 48.6 V, categorized as Stage 2. The application of STVS device in the track circuit of the signaling system reduced the transient voltage by diversion of the Transient Current or ISTVS through the STVS device into the ground system or the clamping voltage at the STVS device. This prevented the transient power from flowing into and damaging the relays of the track circuit, leaving only the clamping voltage with a missing peak wave. This contributed to the stability of the track circuit within the railway signaling system while also raising the Safety Integrity Level (SIL) to a higher standard, in accordance with the specifications of IEC 16508-4 and the unique requirements of the State Railway of Thailand. These enhancements increased the advanced safety system within the track circuit, particularly for train control and train operation functions of the State Railway of Thailand
Application of the multi-criteria analysis method mairca, spotis, comet for the optimisation of sustainable electricity technology development
Authors: Tran Ngoc-Tien 
Published: February 2024

The development of sustainable electricity technology is of utmost importance in addressing the increasing energy demand while mitigating greenhouse gas emissions. Fossil fuel-based electricity generation is the primary contributor to air pollution and climate change, necessitating a shift towards renewable energy sources. The efficient production, distribution, and utilization of energy resources, along with ensuring affordable energy access and environmental sustainability, are key policy objectives for any country's energy sector. However, assessing sustainable electricity technologies is a complex task due to the diverse range of evaluation criteria and impacts associated with the practical implementation of these solutions. To overcome this challenge, this study proposes a multi-criteria decision-making (MCDM) approach to select the optimal solution for the development of sustainable electricity technology. The study employs several reliable methods, including MAIRCA, SPOTIS, COMET, and the CRITIC weighting method, to perform ranking evaluations. Based on this, an evaluation Table of criteria using linguistic variables is constructed. Furthermore, a ranking of methods for developing sustainable electricity technology is established by combining MCDM optimization methods. The results indicate that future energy policies should prioritize sustainable energy technologies, particularly water and solar thermal solutions. These findings have significant implications for development policymakers as the transition towards a sustainable energy system becomes increasingly crucial. In the future, the findings of this research can be further developed on a regional level, enabling the identification of the most appropriate energy technologies for specific regions based on their unique characteristics and requirements
