Modelling Passenger Loyalty towards App-based Motorcycle Taxi

This study evaluates the effect of both service quality and mobile application quality on passenger loyalty towards application-based motorcycle taxi (AMT) services. The data employed for this study were collected from 319 AMT service users in Bandung, Indonesia. To analyse the data, partial least squares structural equation modelling (PLS-SEM) was used to check the influence of both service quality and application quality on passenger loyalty and their indirect influence through passenger perceived value and passenger satisfaction. The result shows that the passenger perception of mobile app quality is an important driver of passenger loyalty towards AMT services. Further, this study suggests that the effect of both service quality and mobile app quality on passenger loyalty is via strengthening passenger perceived value and satisfaction. Finally, this study’s findings reveal the important role of mobile app quality as the determinant of AMT service quality. This study provides a venue for AMT business managers to improve their business performance by developing both service quality and mobile app quality.
The origin of the endemic African grasshopper family Lentulidae (Orthoptera: Acridoidea) and its climate‐induced diversification

Forest relicts in the mountainous regions of Africa represent one of the most diverse ecosystems on our planet, but the processes that have generated this remarkable diversity are still poorly understood. We estimate divergence times for an endemic, flightless grasshopper family and reconstruct a potential scenario for their colonization of Africa to test the hypothesis that the diversity of these mountain‐top endemics has been generated by multiple fragmentations and reconnections of tropical rain forests in parallel with climatic fluctuations.

A Printed Yagi Antenna for CubeSat with Multi-Frequency Tilt Operation

In this paper, a printed Yagi antenna with an integrated balun is proposed for CubeSat communications. The printed antenna is mechanically adjustable to realize three functional states at different operating frequencies in the L-band and S-band respectively. Three different angle deployments are proposed at 10°, 50° and 90°, so that the antenna operates at three different operating frequencies, namely 1.3 GHz (L-band), 2.4 GHz (S-band) and 3 GHz (S-band). The measured results of the fabricated antenna are well matched with the simulation, having frequencies of 2.82–3.07 GHz, 1.3–1.4 GHz and 2.38–2.57 GHz, with similar radiation patterns. The measured gain of the antenna is 8.167 dBi at 2.4 GHz, 5.278 dBi at 1.3 GHz and 6.120 dBi at 3 GHz. Keeping within the general theme of cheap off the shelf components for CubeSats, this antenna design allows the CubeSat designers to choose from three popular frequencies, through a simple angle configuration. The main contribution of this work lies with the reconfigurable frequency, relatively high gain and simplicity of design.

Identical parallel machine scheduling with discrete additional resource and an application in audit scheduling

Resource scheduling has been one of the most prominent problems due to its technical challenges and prevalence in real-life. In this paper, we focus on an extension of the parallel machine scheduling problem with additional resources, which can be classified as a static resource-constrained parallel machine scheduling problem with unspecified job-machine assignment. The novelty of the problem we tackle stems from the additional resource that consists of components with discrete levels. The allocation of this resource to machines induces general covering constraints. This distinct characteristic of the additional resource also arises in a real-life audit scheduling problem, in which local branches of a financial firm are to be audited by a set of auditors with different experience levels. The quantification of the auditor experience and the branch experience requirement enable us to model this problem as an extension of the aforementioned scheduling problem with extra constraints related to the auditing process. We propose mathematical models for these problems and two constructive heuristic algorithms. The upper bounds attained by these algorithms are improved by a tabu-search algorithm, and an efficient lower bounding technique is developed for comparative purposes. We conduct extensive computational experiments to assess the performance of the proposed algorithms.

Effect of calcination temperature on properties of waste alkaline battery-based catalysts for deep oxidation of toluene and o-xylene

To evaluate waste alkaline battery (WB) as a catalyst for deep oxidation of toluene and o-xylene, we investigated how calcination temperature influenced the catalytic activity of WB-based catalyst for catalyst preparation. Physicochemical properties of WB-based catalysts were characterized by BET (Brunauer Emmett Teller) analysis, XRD (X-ray diffraction), SEM/EDX (scanning electron microscope/energy dispersive X-ray), TGA/DTA (thermo gravimetric analysis/differential thermal analysis), and H2-TPR (hydrogen temperature programmed reduction). Major elements of WB-based catalysts were carbon, manganese, zinc, and iron. The catalytic activity of WB-based catalyst was significantly influenced by calcination temperatures ranging from 300 °C–600°C. An increase calcination temperature resulted in a significant decrease in the BET surface area and concentrations of surface carbon and chlorine of the WB-based catalyst, while levels of other components increased. The average pore diameter of the WB-based catalyst calcined at 400 °C (WB (400) catalyst) was the smallest. The concentrations of manganese and iron in WB (400) catalyst were the highest, while those of manganese and iron in the WB-based catalyst calcined at 300 °C (WB (300) catalyst) were the lowest. Therefore, a good performance of WB (400) catalyst was likely due to its higher concentrations of manganese and iron and smaller pore size. When GHSV (gas hourly space velocity) was 40,000 h−1, toluene and o-xylene were completely oxidized on WB (400) catalyst at 430 °C and 440 °C, respectively.
Experimental Characterization of Pantograph Arcs and Transient Conducted Phenomena in DC Railways

An electric arc is an example of a transient event that is quite common in electrified transportation systems as by-product of the current collection mechanism. As a broadband transient, an electric arc excites a wide range of (often oscillatory) responses related to the substation and onboard filters, as well as the line resonances and anti-resonances. Similarly do the charging of onboard filter and other related inrush events. This work considers the electrical characteristics of these transients and of the excited responses in order to define their typical spectral signatures in DC railways and take them into account concerning their impact on Power Quality measurements and the measurements of instruments deployed onboard.
Photochemistry of Methane and Ethane in the Martian Atmosphere

We develop an existing 1‐D photochemistry model to include a comprehensive description of organic chemistry on Mars that includes the oxidation products of methane (CH4) and ethane (C2H6),a longer‐chain hydrocarbon that can be used to differentiate between abiotic and biotic surface releases of CH4. We find that CH4 is most volatile between 20 and 50 km during Mars' northern summer, where the local atmospheric CH4 lifetime lowers to 25–60 years. We study atmospheric formaldehyde (HCHO) and formic acid (HCOOH), as the two common oxidation products of CH4 and C2H6, and acetaldehyde (CH3CHO) and acetic acid (CH3COOH) as unique products of C2H6. We focus our analysis of these gases at Mars' aphelion and perihelion at latitudes between ‐30° and 30°, altitudes from the surface to 70 km, and from a homogeonous initial condition of 50 pptv of CH4 and C2H6. From this initial condition, CH4 produces HCHO in a latitude‐independent layered structure centered at 20–30 km at aphelion with column‐averaged mixing ratios of 10−4 pptv, and oxidation of C2H6 produces HCHO at 10−2 pptv. Formic acid has an atmospheric lifetime spanning 1–10 sols below 10 km that shows little temporal or zonal variability and is produced in comparable abundances (10−5 pptv) by the oxidation of C2H6 and CH4. We also find that oxidation of 50 pptv of C2H6 results in 10−3 pptv of CH3CHO and 10−4 pptv of CH3COOH. Subsequent UV photolysis of this CH3CHO results in 10−4 pptv of atmospheric CH4, potentially representing a new atmospheric source of Martian CH4.
Discriminate Raman/GFP Spectra of Yeast Mitochondria Using Convolutional Neural Network

Raman spectroscopy is one of the well-known techniques that be able to identify molecular species in the complex system. In the present work, 633 nm Raman laser and GFP excitation light are irradiated at the sample simultaneously. It allows us to know whether Raman spectra are indeed taken from mitochondria. However, the mixture spectra of RamanlGFP are very complicated and impossible to correctly identify manually. Therefore, convolutional neural network is integrated to our work in order to distinguish RamanlGFP spectra with and without signal from GFP as GFP-positive and GFP-negative spectra, respectively. The system architecture is the adapted visual geometry group (VGG) with 14 convolutional layers. Batch normalization is added, and fully-connected layer is increased to 5 layers. Various size of RamanlGFP images were used to train our VGG network. The black and white background color also provided to gain the best result. The highest accuracy of 87.42% was achieved to separate GFP-positive and -negative spectra with black background and 68⨯52 pixel images. In the final step, the separated GFP-positive and -negative spectra were distributed in two different folders for further Raman spectra analysis of mitochondria.
RELATIONS BETWEEN WORKPLACE BULLYING, CONSCIENTIOUSNESS AND COUNTERPRODUCTIVE WORK BEHAVIOURS: A STUDY AT LOGISTICS COMPANY

Employee behaviors gets popular in today’s academic and business environment because of its impact on organizational outcomes. Especially, increase of the dark attitudes of managers and colleagues towards the individuals, affects the formation of employees’ deviance behaviors. In this context, workplace bullying is considered as one of the types of destructive approaches in organizations that excluding someone in social environment or influencing co-workers job sustainability with the harassment and offending emotions. Rising of workplace bullying in organizations leads employees to demonstrate negative behaviors which are defined as counterproductive work behaviors. On the other side, personality traits of an employee may have a major role in transformation of perception of negative attitudes towards to the work outcomes. For this reason, it was aimed to find out the role of conscientiousness, one of the personality traits of Five Factor Model, in the interaction between workplace bullying and counterproductive work behaviors. Statistical analyzes were made with the participation of 204 employees of a logistics company. According to findings it was revealed out that conscientiousness has a moderation role in the interaction between workplace bullying and counterproductive work behaviors.
LASER STUDY ON THE RESONANCE-ENHANCED MULTIPHOTON ELECTRON DETACHMENT (REMPED) PROCESSES FOR C60- AND C70-

The resonance-enhanced multiphoton electron detachment (REMPED) spectra for C[sub 60][sup [minus]] and C[sub 70][sup [minus]] have been obtained. They are regarded as the absorption spectra for these fullerene anions in the gas phase. The REMPED spectrum of a fragment anion produced in the fragmentation process of C[sub 70][sup [minus]], having a mass of 720, has been measured. This spectrum shows a threshold identical to that of C[sub 60][sup [minus]] at ca. 8200 cm[sup [minus]1]. Thus the fragment anion is assigned to C[sub 60][sup [minus]] with the icosahedral structure. The REMPED spectrum of C[sub 70][sup [minus]] shows a broad band in the near-infrared region. The nature of the appearance of this band is discussed in consideration of the ground electronic state for C[sub 70][sup [minus]]. 14 refs., 3 figs.
Applications pour le changement de comportement : quelle approche pour une implication active et éthique des utilisateurs?

Une quantite considerable d’applications sont developpees pour des objectifs de sante divers (gestion de maladie chronique, sante mentale .). Pourtant l’utilisation en terrain reel de ces applications semble rester minoritaire. A partir de la litterature, diverses limites pouvant expliquer ce phenomene sont avancees, certaines restent d’actualite bien que discutees depuis des annees. La multiplicite des domaines et des terminologies impliques reste un frein aux echanges fructueux. Le developpement d’applications ancrees dans une theorie de changement de comportement reste minoritaire. Une question moins soulevee mais tout aussi importante est la place de l’utilisateur dans la conception de ces applications, bien souvent relegue a une position passive dans l’approche de sa propre sante. Enfin, une attention particuliere doit etre portee aux questions ethiques d’outils visant un changement de comportement.

Morfologia do órgão vomeronasal da paca (Cuniculus paca Linnaeus, 1766)

RESUMO: O órgão vomeronasal é um receptor químico capaz de detectar feromônios e por essa razão está envolvido nos comportamentos reprodutivos, sociais e de defesa. A reprodução de pacas tem se destacado na área de comercialização de carne e para fins conservacionistas e de pesquisa, como modelo experimental. Diante da necessidade do detalhamento da morfologia do sistema olfatório secundário, o sistema vomeronasal, foi descrita a anatomia macroscópica, anatomia microscópica e topografia do órgão vomeronasal (OVN) da paca (Cuniculus paca). Foram utilizadas cinco pacas adultas do Setor de Animais Silvestres da FCAV, UNESP, Jaboticabal-SP. Após a eutanásia dos animais, a solução fixadora de formaldeído 10% em tampão fosfato de sódio (PBS) foi perfundida sistemicamente (via aorta ascendente). Mediante dissecação, o OVN foi localizado e individualizado para a descrição topográfica e anatômica. Posteriormente, foi isolado e incluído em parafina plástica. Cortes de cinco micrômetros foram corados com Hematoxilina-Eosina. O OVN encontra-se no assoalho da cavidade nasal em ambos os lados da base do septo nasal e está relacionado com o osso vômer, processos palatinos dos ossos pré-maxilar e maxilar. Rostralmente, comunica-se com a cavidade oral estabelecendo relação com a papila incisiva. É um órgão par com superfície irregular, levemente elíptico em secção transversal, apresentando coloração amarronzada repleta de vasos sanguíneos. À microscopia de luz, notou-se presença da cartilagem vomeronasal. O órgão é revestido por um epitélio não sensorial e neurossensorial.
Synthèse et étude des propriétés physico-chimiques des poly(butylène succinate)s linéaire et branché

Le poly(butylene succinate) (PBS) est un polyester aliphatique biodegradable dont les proprietes en font un bon candidat pour le remplacement des polyolefines. De plus, ses deux monomeres, l'acide succinique et le butane-1,4-diol, peuvent etre issus de la biomasse via un procede de fermentation de sucres. L'etude realisee ici a ete separee en deux grandes parties : le PBS lineaire d'une part et le PBS branche d'autre part. La premiere partie montre que la cinetique de synthese du PBS suit bien le modele d'esterification etabli par Flory. Par la suite, l'etude des proprietes physico-chimiques du PBS a permis de remonter a des parametres comme la masse molaire critique d'enchevetrement, le module du plateau caoutchoutique, l'energie d'activation du PBS fondu ou encore les parametres de l'equation Mark-Houwink-Sakurada. Une etude sur ses proprietes thermiques a permis de decrire l'evolution de son comportement en fonction de sa masse molaire. Enfin, le profil d'energie potentielle de l'esterification entre l'acide succinique et le butane-1,4-diol a ete trace en utilisant un outil de chimie quantique. La seconde partie traite de l'etude de PBS branches obtenus en employant des agents de branchement (polyols) pouvant etre issus de la biomasse comme l'huile de ricin, le glycerol et le polyglycerol. La strategie adoptee a ete le couplage entre un oligomere PBS fonctionnalise acide carboxylique et les agents de branchement. L'etude en presence d'huile de ricin a mis en avant les relations entre la structure, determinee en SEC-Triple Detection, et les proprietes physico-chimiques du PBS branche. L'optimisation de la synthese en presence de glycerol ou de polyglycerol a ete abordee a partir de la methode des plans d'experiences. Compare a la methode « un facteur a la fois », des resultats prometteurs et semblables a ce qui est rapporte dans la litterature ont ete obtenus pour l'etude du PBS branche en presence de glycerol.
Leveraging Monostable and Bistable Pre‐Curved Bilayer Actuators for High‐Performance Multitask Soft Robots

Soft actuators are typically designed to be inherently stress‐free and stable. Relaxing such a design constraint allows exploration of harnessing mechanical prestress and elastic instability to achieve potential high‐performance soft robots. Here, the strategy of prestrain relaxation is leveraged to design pre‐curved soft actuators in 2D and 3D with tunable monostability and bistability that can be implemented for multifunctional soft robotics. By bonding stress‐free active layer with embedded pneumatic channels to a uniaxially or biaxially pre‐stretched elastomeric strip or disk, pre‐curved 2D beam‐like bending actuators and 3D doming actuators are generated after prestrain release, respectively. Such pre‐curved soft actuators exhibit tunable monostable and bistable behavior under actuation by simply manipulating the prestrain and the biased bilayer thickness ratio. Their implications in multifunctional soft robotics are demonstrated in achieving high performance in manipulation and locomotion, including energy‐efficient soft gripper to holding objects through prestress, fast‐speed larva‐like jumping soft crawler with average locomotion speed of 0.65 body‐length s−1 (51.4 mm s−1), and fast swimming bistable jellyfish‐like soft robot with an average speed of 53.3 mm s−1.
A proposal on virtual massive array using fast beam switching and blind algorithm

: In future wireless communication systems, massive multiple-input multiple-output (MIMO) is attracting attention for improving transmission rate. However, there is an issue that a large scale of hardware is needed due to massive numbers of antennas, transmitters, receivers, A/D and D/A convertors in massive MIMO. In this study, we propose a method to realize a virtual massive array with only one receiver by changing the beam pattern and performing A/D conversion at high speed within one symbol. The basic performance and eﬀectiveness of the proposed method is demonstrated via a computer simulation.
