A Comparison of Lane Marking Detection Quality and View Range between Daytime and Night-Time Conditions by Machine Vision

Lateral support systems in vehicles have a high potential for reduction of lane departure crashes. To profit from their full potential, such systems should function properly in adverse conditions. Literature indicates that their accuracy varies between day and night-time. However, detailed quantifications of the systems’ performance in these conditions are rare. The aim of this study is to investigate the differences in detection quality and view range of Mobileye 630 in dry daytime and night-time conditions. On-road tests on four rural road sections in Croatia were conducted. Wilcoxon signed-rank test was used to test the difference between the number of quality rankings while absolute average, average difference and standard deviation were used to analyse the view range. Also, a paired samples t-test was used to test the difference between conditions for each line on each road. The overall results confirm that a significant difference in lane detection quality view range exists between tested conditions. “Medium” and “high” detection confidence (quality level 3 and 2), increased by 5% and 8% during night-time compared to daytime while level 0 (“nothing detected”) decreased by 12%. The view range increased (almost 16% for middle line) during daytime compared to night-time. The findings of this study expand the existing knowledge and are valuable for research and development of machine-vision systems but also for road authorities to optimize the markings’ quality performance.
Estimation of Harmonic Emission of Electric Vehicles and Their Impact on Low Voltage Residential Network

The EV penetration in the low voltage residential grids is expected to increase rapidly in the coming years. It is expected that EV consumers will prefer overnight home charging because of its convenience and lack of charging infrastructure. The EV battery chargers are nonlinear loads and likely to increase the current harmonic emission in the distribution network. The imminent increase of EV load requires upgrading or managing the existing power system to support the additional charging load. This paper provides the estimation of the current harmonic emission of the EV charging load at different voltage distortions using the stochastic EV load model. The impact of EV charging on the distribution transformer is also presented.
APPROACH FOR THE DEVELOPMENT AND APPLICATION OF TARGET PROCESS MODULE SETS

Abstract The implementation of agile frameworks, such as SAFe, in large companies causes conflicts between the overall product development process with a rigid linkage to the calendar cycles and the continuous agile project planning. To resolve these conflicts, adaptive processes can be used to support the creation of realistic target-processes, i.e. project plans, while stabilizing process quality and simplifying process management. This enables the usage of standardisation methods and module sets for design processes. The objective of this contribution is to support project managers to create realistic target-processes through the usage of target-process module sets. These target-process module sets also aim to stabilize process quality and to simplify process management. This contribution provides an approach for the development and application of target-process module sets, in accordance to previously gathered requirements and evaluates the approach within a case study with project managers at AUDI AG (N=21) and an interview study with process authors (N=4) from three different companies.
Raptor reintroductions: Cost‐effective alternatives to captive breeding

Reintroductions are becoming a popular tool to prevent extinctions, although their overall success rate is low. Assessing the efficiency and cost‐effectiveness of different reintroduction strategies may help identify and promote efficient practices. Captive‐breeding is widely used in animal reintroductions, although concerns have been raised about relatively high failure rates and economic costs. Here, we compared the effectiveness of two simultaneously used strategies in the reintroduction of the Bonelli’s eagle on the island of Mallorca: The release of captive‐bred chicks and wild‐reared, translocated non‐juveniles. To do so, we estimated the main vital rates for individuals released by both strategies and used these to perform population simulations to assess their overall performances. The use of wild‐reared non‐juveniles showed a trend with higher numbers of breeding pairs 10 years after the end of releases (14.75 pairs, 95% CI 4–25 vs. 11.21 pairs, 95% CI 2–24) and was the only strategy that prevented extinction in the long term. Following that, based on cost estimations of every strategy and different reintroduction budgets, we assessed the cost‐effectiveness of releasing wild‐reared non‐juveniles compared with two captive‐breeding alternatives: Releasing chicks either originally from breeding programmes or extracted from nests in natural populations. Again, releasing wild‐reared non‐juveniles was the only strategy that prevented long‐term extinction in all economic scenarios (i.e. low‐budget scenario 21.49 pairs, 95% CI 2–25). The use of chicks sourced from captive‐breeding programmes did not guarantee long‐term persistence even in high‐budget scenarios (14.50 pairs, 95% CI 0–25). Releasing wild‐reared non‐juveniles boosts early recruitment to the breeding population and early reproduction, which can be key for reintroduction success. However, in some scenarios, post‐release effects can be stronger in wild‐reared individuals, especially because of high translocation stress and post‐release dispersal. Hence, we recommend undertaking careful evaluation of the pros and cons of every strategy and embracing adaptive management to choose best strategies.
Marketing Communication Program Design of Online Travel Agent Kliktrip Using Benchmarking and Analytical Hierarchy Process Methods

Kliktrip is an Online Travel Agent (OTA) that has trip & activities facilities and was established in 2018 in Bandung. Kliktrip sales are still experiencing a decline due to low public awareness of Kliktrip which is seen through the number of downloads on mobile apps and Instagram followers. Kliktrip sales are still experiencing a decline and public awareness of Kliktrip is still low because Kliktrip has not implemented 7 out of 8 marketing communication mix optimally. Therefore, research was conducted to design an effective marketing communication program for Kliktrip by using benchmarking and Analytical Hierarchy Process (AHP) methods. Based on the results of AHP data processing, it can be seen that the selected benchmark partner is Explorer.id with a total priority vector value of 0.44 and benchmark results with Explorer.id concluded that Kliktrip needs to increases the value of SEO, page views, and unique visitors on the website, creates a Tiktok’s account, webisode, and video podcasting, collaborates with cross-promotion, makes contests (giveaways), increase the number of downloads and reviewers on mobile apps, implementing mobile billboards and cause-related marketing, increasing customer service operational time, participating in exhibitions, and collaborating with influencers.
Rainwater harvesting (RWH): a supplement to domestic water supply in Mvog-Betsi, Yaoundé-Cameroon

This research is aimed at assessing the possibility of using a rainwater harvesting (RWH) system to supplement domestic water supply in the Mvog-Betsi neighbourhood of Yaoundé. The research made use of a 63-year long data series on the amount of rainfall available in the study area, an analysis of rainwater quality and an estimate of the population's monthly water demand in relation to the monthly harvestable rainwater supply. Rainwater supply for the months of September, October and November is 53.05 m3 which is considerably greater than the households' water demand of 25.56 m3 during the long dry season. This led to the design of a 27 m3 ferrocement tank as minimum storage requirement. Furthermore, a rainwater quality analysis showed that all tested parameters conform to water quality standards except for microbiological quality. The rainwater needs to be disinfected before consumption as potable water. Finally, cost estimates for installing RWH systems for low ($419), medium ($549) and high standard ($668) habitations were calculated. RWH can effectively serve as a water supply supplement in the Mvog-Betsi neighbourhood.
PREVALENCE AND FACTORS ASSOCIATED WITH ROUTINE MEDICAL CHECKUP AMONG PATIENTS ATTENDING MASAKA REGIONAL REFERRAL HOSPITAL, UGANDA

Globally, Routine Medical checkup is known to be a preventive medicine that opens doors for assessment of well-being status of all individual and decreases the mortality and morbidity of different ailments in communities. attending health checkups may be one of the key reasons of controlling the predisposition and cause of much of the illness, suffering and early death related to chronic illnesses and condition. Its on this ground that this current study sought to elucidate further on factors determining the adherence of people to medical checkups. A descriptive cross-sectional study was carried out among 385 adult respondents attending Masaka regional referral hospital, in Uganda. A structured questionnaire involving open-ended and close-ended questionnaire was used and data was analyzed using SPSS version 26. Overall, 61.3% of study participants have ever heard of routine health check-ups citing hospitals (25.7%) as the most used source of the information. A prevalence of 43.4% represents the percentage of those who do routine health check-up and of which majority engage in only a general examination (14.5%). Overall, more than half of the respondents (56.6%) have never participated in routine health check-ups with their reported reasons of not feeling sick (25.97%). Factors like level of education, Employment, Occupational, exercise practices and level of awareness was statistically significant to uptake of routine heath checkup among the respondent at P< (0.005). Low health check-up rates may translate into inability to detect and intervene with early health challenges among respondents, and this is whereeffort is needed in ensuring that routine health check-up is encouraged especially during times when patients are healthy. There is need to strengthen government efforts and other concerned NGOs to put across specific sensitization programs about routine health check-ups on different media platforms and also utilize other social public means.
Students’ Blended Learning Course Experience Scale (BLCES): development and validation

ABSTRACT The aim of this study was to develop a scale to measure students’ blended learning course experience. A total of 792 undergraduate students from Malaysia participated in this study. Exploratory factor analysis (EFA) was employed to evaluate the factor structure of the scale. As a result of EFA, three factors with 19 items that explained 68.06% of the total variance were obtained. The three factors are: course design, learning experience, and personal factors. Confirmatory factor analysis (CFA) was used to establish the structural validity of the scale, and item discrimination was conducted to validate the scale. The Cronbach’s coefficients (α) for the factors ranged from . 71 to . 95. The overall Cronbach’s coefficient (α) of the scale was . 92, demonstrating a satisfactory level of reliability. The results showed that the developed scale is reliable and valid. Future implications for course designers and instructors are discussed.
How Does Environmental Interpretation Affect Psychological Well-Being? A Study Conducted in the Context of COVID-19

The COVID-19 crisis has challenged and generated severe impact on the global society, economy, and environment. Under this pandemic context, governments and organizations around the world have issued and strengthened environmental policies and regulations to protect the environment and human health. However, the extant knowledge about how people’s interpretation of environmental policies and regulations influence their psychological well-being in the context of the COVID-19 pandemic is still limited. This study, therefore, investigates the impact of environmental interpretation on psychological well-being with the mediating role of environmentally responsible behavior and the moderating role of psychological contract violation. Using the data from a large sample of 960 residents in China, results of structural equation modeling show a positive relationship between environmental interpretation and psychological well-being, and this relationship is mediated by environmentally responsible behavior. Notably, psychological contract violation has a moderating effect on the indirect effect of environmental interpretation on psychological well-being via environmentally responsible behavior. These findings have several important implications for policymakers in environmental sustainability and pandemic planning.
On the Real‐Time Atomistic Deformation of the CoNiCrFeMn High‐Entropy Alloy with Gradient Structures

Molecular dynamic simulations are used to correlate gradient structure and mechanical properties of a CoNiCrFeMn high‐entropy alloy (HEA) by characterizing the structural evolution and dislocation substructures during tensile loading. The gradient distributions of deformation faults, dislocations, and grain size from the surface to the center of samples are explored in detail. Quantitative analysis indicates that improvement of strength is attributed to the high densities of dislocations and deformation faults in the grain interior. Moreover, the results reveal that the energy barrier for nucleation of deformation faults in the deformed layer of gradient HEA is higher than that of the ungradient sample. The high strength and work hardening of gradient HEA areattributed to the bundles of concentrated dislocations, which are distributed in grain interiors. This study helps to fundamental understanding of the deformation mechanisms of HEAs with gradient structure, which can be used to strength‐ductility trade‐off.
Immersion and invariance disturbance observer-based nonlinear discrete-time control for fully actuated mechanical systems

This paper addresses the attenuation problem of input disturbances in the control of fully actuated mechanical systems in the discrete-time setting. Firstly, a discrete-time disturbance estimator design with immersion and invariance (I&I) approach is presented for the n-degrees of freedom (DOF) fully actuated mechanical systems. Then, a discrete-time combined feedback linearising and backstepping control is established that this controller uses the estimated disturbance information. Global asymptotic stability of the estimator and local asymptotic stability of the entire closed-loop system in an arbitrarily large compact set are shown utilising the Lyapunov stability theory. In order to show the effectiveness of the proposed composite observer-based discrete-time control method, it is applied to the 3-DOF robotic manipulator. Performance of proposed direct discrete-time combined feedback linearising and backstepping controller with discrete-time I&I observer is compared with a direct discrete-time conventional second-order sliding mode controller with another discrete-time nonlinear disturbance observer via simulations. The superior performance of the proposed method is demonstrated with simulation results.
On-demand retrieval of cells three-dimensionally seeded in injectable thioester-based hydrogels

Scaffold systems that can easily encapsulate cells and safely retrieve them at the desired time are important for the advancement of cell-based medicine. In this study, we designed and fabricated thioester-based poly(ethylene glycol) (PEG) hydrogels with injectability and on-demand degradability as new scaffold materials for cells. Hydrogels can be formed in situ within minutes via thioester cross-linking between PEG molecules and can be degraded under mild conditions in response to l-cysteine molecules through thiol exchange occurring at the thioester linkage. Various cell experiments, especially with sucrose, which enables the adjustment of the osmotic pressure around the cells, showed that the damage to the cells during encapsulation and degradation was minimal, indicating the capability of on-demand retrieval of intact cells. This hydrogel system is a versatile tool in the field of cell-based research and applications such as tissue regeneration and regenerative medicine.
Model analyses show how biodiversity conservation could reduce infectious diseases in an ecosystem

Biodiversity conservation benefits the sustainability of the environment and also the well‐being of humanity. Here we consider the possible importance of biodiversity of resources in limiting disease. With this aim we formulate a dynamical system model for a terrestrial ecosystem that takes into account, biodiversity of resources together with competition among species. The dynamics of the model are explored using appropriate dynamical system analyses. The effects of the competition terms and carrying capacity on the dynamics of the model are considered in terms of which ranges allow sustainability of the system. Simulations illustrate how biodiversity conservation can of itself lead to reduction in infectious diseases in an ecosystem.
SeUpdate: Secure Encrypted Data Update for Multi-User Environments

Searchable Symmetric Encryption (SSE) is a key tool for secure data processing. To date, most of the SSEs were studied alone, while an SSE supporting update operations over encrypted data remained a challenging problem due to various statistical attacks and multi-user environments. In this article, we propose SeUpdate, the first SSE scheme that simultaneously achieves keyword search and controlled update over encrypted data, with flexible read (search) and write (update) access control policies among multiple users. In SeUpdate, users do not need to share secret keys and a single query enables one to efficiently search all his authorized data. We formally define a security model, and prove our scheme have both forward and backward security. We note that the write permission of an SSE is realized for the first time. We further extend the basic scheme with dynamic access policy update and support of a large number of files. We also implement SeUpdate and some related work. The theoretical and experimental analyses demonstrate our scheme and its extension are practical and efficient.
Unique volatile chemical profiles produced by indigenous and commercial strains of Saccharomyces uvarum and Saccharomyces cerevisiae during laboratory-scale Chardonnay fermentations

Each wine growing region hosts unique communities of indigenous yeast species, which may enter fermentation and contribute to the final flavour profile of wines. One of these species, Saccharomyces uvarum, is typically described as a cryotolerant yeast that produces relatively high levels of glycerol and rose-scented volatile compounds as compared with Saccharomyces cerevisiae, the main yeast in winemaking. Comparisons of fermentative and chemical properties between S. uvarum and S. cerevisiae at the species level are relatively common; however, a paucity of information has been collected on the potential variability present among S. uvarum strains. The objective of this study was to compare the fermentation kinetics and production of volatile compounds between indigenous and commercial Saccharomyces strains at different temperatures. We compared laboratory-scale fermentation of Chardonnay juice at 15 °C and 25 °C for 11 Saccharomyces yeast strains (six indigenous S. uvarum, one commercial S. uvarum, one indigenous S. cerevisiae and three commercial S. cerevisiae). Fermentation kinetics and the production of volatile compounds known to affect the organoleptic properties of wine were determined. The indigenous S. uvarum strains showed comparable kinetics to commercially sourced strains at both temperatures. Volatile compound production among the strains was more variable at 15 °C and resulted in unique chemical profiles at 15 °C as compared with 25 °C. Indigenous S. uvarum strains produced relatively high levels of 2-phenylethyl acetate and 2-phenylethanol, whereas these compounds were found at much lower levels in fermentations conducted by commercial strains of both S. cerevisiae and S. uvarum. Production of glycerol by indigenous S. uvarum strains did not differ from commercial strains in this study. Our findings demonstrate that indigenous strains of S. uvarum show functional variation among themselves. However, when compared with commercial S. cerevisiae and S. uvarum strains, they have comparable fermentation kinetics but unique volatile compound profiles, especially at low fermentation temperatures.
Behavioral and Physiological Signals-Based Deep Multimodal Approach for Mobile Emotion Recognition

With the rapid development of mobile and wearable devices, it is increasingly possible to access users’ affective data in a more unobtrusive manner. On this basis, researchers have proposed various systems to recognize user’s emotional states. However, most of these studies rely on traditional machine learning techniques and a limited number of signals, leading to systems that either do not generalize well or would frequently lack sufficient information for emotion detection in realistic scenarios. In this paper, we propose a novel attention-based LSTM system that uses a combination of sensors from a smartphone (front camera, microphone, touch panel) and a wristband (photoplethysmography, electrodermal activity, and infrared thermopile sensor) to accurately determine user’s emotional states. We evaluated the proposed system by conducting a user study with 45 participants. Using collected behavioral (facial expression, speech, keystroke) and physiological (blood volume, electrodermal activity, skin temperature) affective responses induced by visual stimuli, our system was able to achieve an average accuracy of 89.2 percent for binary positive and negative emotion classification under leave-one-participant-out cross-validation. Furthermore, we investigated the effectiveness of different combinations of data signals to cover different scenarios of signal availability.
