Evaluation framework for mobile ticketing applications in public transit: a case study

Both in the US and abroad, various transit agencies have started to implement mobile ticketing applications, which save commuters time during ticket purchase and allows them to avoid surcharges typically incurred when purchasing tickets on-board. Mobile ticketing applications also have a high potential to help transit agencies reduce costs, give them a better understanding of commuter behaviour, and allow them to make their services more efficient. However, it is not a straightforward task to predict the customers’ reaction and gain their trust and to increase the adoption rate of this relatively new technology. A comprehensive evaluation plan is required to detect and fix critical usability problems during both the application development and system wide implementation phases. To address this need, a four-stage evaluation framework is proposed in this study for mobile ticketing technologies in public transit to improve their usability and enhance their adoptability by the potential users. The proposed evaluation framework was employed when New Jersey transit's mobile ticketing application, MyTix, introduced in 2013, was being developed.
A new method for texture classification based on wavelet transform

The wavelet transform provides several important characteristics which can be used in a texture classification problem. We present a new algorithm based on conventional pyramid-structured wavelet transform. The iteration of the basic decomposition is submitted to a variance criterion which is applied on the current lowpass subimage. This criterion helps to decide the level where the decomposition have to be stopped. This level depends on the texture properties. It is used as a feature to assign textures into different classes. Form factors computed from wavelet decomposition are then used to perfect the classification process in each class. The performance of our method is pointed out on various images and compared with Laws's (1980) texture classification results.
Provincial and Territorial Variation in Barriers in Accessing Healthcare for Children and Youth With Mental and Neurodevelopmental Health Concerns in Canada

Mental and neurodevelopmental disorders are the two leading contributors to morbidity worldwide. Both classes of disorders emerge early in the life course and are associated with delays in social, and emotional development, burdening those affected and society as a whole.2–4 Early intervention is critical for preventing worsening symptoms and impairment and achieving optimal outcomes. Evidence suggests that many Canadian children and youth (aged 1–17), particularly those with mental health and developmental difficulties, experience barriers to accessing healthcare, which are disproportionately distributed across population subgroups and by class of disorder. In particular, females, immigrants and refugees, Indigenous and racialized subgroups, low-income households, rural residents, and members of the LGBTQ+ community may experience greater barriers to accessing care for mental and neurodevelopmental concerns.5–7 A strategic priority of the Mental Health Commission of Canada is establishing equity in mental health care delivery for children and youth. Indicators used to evaluate equitable service delivery include measures of self-reported barriers to accessing care, which incorporates aspects of both need and service delivery. As mental health care is provincially/territorially mandated in Canada, there is also variation in service delivery, which in turn may lead to variations in how children and youth are able to access care. Prior evidence on barriers to care in Canada is sparse. Yet, recent evidence from the 2019 Canadian Health Survey on Children Youth (CHSCY) provides an opportunity to address data gaps by quantifying the prevalence of barriers in accessing care for mental and neurodevelopmental health concerns among children and youth across all provinces and territories and examining differences in prevalence according to population characteristics.

Mechanics of Fast Force Recovery in striated muscles

Cette these est consacree a la modelisation de la reponse transitoire d'une fibre musculaire squelettique soumise a des sollicitations mecaniques rapides. A l'echelle du nanometre, la fibre musculaire contient des filaments d'actine et de myosine regroupes en unites contractiles appelees "sarcomeres". Le filament de myosine est un assemblage de moteurs mol eculaires qui, en presence d'ATP, s'attachent et se d etachent p eriodiquement au filament d'actine. Au cours de ce processus d'attachement-detachement, la myosine genere une force lors d'un changement de conformation appele "power-stroke". Ses caracteristiques peuvent etre etudiees lors de la reponse transitoire de la fibre soumise a des sollicitations mecaniques rapides. Nous proposons un modele mecanique innovant du demi-sarcomere permettant de relier les caracteristiques de la myosine a la reponse de la fibre complete. A la difference des modeles existants, privilegiant une approche discrete, ce modele s'appuie sur la definition d'un potentiel d'energie continu qui prend en compte une interaction de champ moyen entre les moteurs moleculaires. Ce systeme presente des reponses radicallement differentes a longueur imposee et a force imposee. Nous proposons en particulier une explication a la difference de cinetique observee experimentalement. Nous montrons egalement que le demi-sarcomere est m ecaniquement instable ce qui explique les inhomogeneites de longueurs observees dans une myofibrille.
Adaptive Control of Mixed-Interlaced forms

Abstract: In this paper we combine forwarding and backstepping techniques to stabilize mixed interlaced systems. All the signals in the close loop remain semiglobally ultimately bounded the output signal y follows a desired trajectory signal yd, with bounded derivatives up to m order. We also present simulation examples that prove the adaptation of mixed interlaced forms, using a backstepping controller.
Does diversification pay in the app market? Evidence from the Apple App Store and Google Play

In this paper we address the study of the effects of product line diversification on firm performance in the mobile application market. Specifically, we shed light on whether the distribution platform ecosystem where developers commercialize their apps influence the effect of product line diversification, i.e., diversification across different app categories, on developer sales performance. To these purposes, we compare the sales performance of diversified developers with that of category-specialized developers in the two major app stores (namely, Apple’s App Store and Google Play). Our results show that the diversification strategy has a positive impact on developer sales in Google Play, while no significant impact emerges in the Apple’s App Store. The cross-platform differences in consumer willingness to pay are the rationale behind the different effect of diversification on sales performance across platform ecosystems. Our results have an important implication for developers as they suggest that developers should factor in the app ecosystem where they operate when making the decision on whether to diversify or not.
Classical analytic solutions of the non-stationary Navier-Stokes equation in two, three and higher dimensions

In this paper we present a method to derive classical solutions of the Navier-Stokes equations for non-stationary initial value problems in domain $\mathbb{R}^n$ ($n=2,3$ or higher). Exact solutions in $\mathbb{R}^2$ and $\mathbb{R}^3$ in the presence of an externally specified force are obtained by imposing certain restrictions on the initial data.
Economic risk‐based bidding strategy for profit maximisation of wind‐integrated day‐ahead and real‐time double‐auctioned competitive power markets

This study proposes a unique method of bidding strategy which is based on bi-level optimisation model for analysing the profits of the generation companies (GENCOs) and distribution companies in the day-ahead and real-time competitive power markets. The bi-level optimisation problem includes lower-level and upper-level problems. In the lower-level problem, market clearing model is presented, in which market clearing problem is solved, locational marginal price is minimised at load buses, net generation cost is also minimised with a simultaneous increase in profit with optimal placement of wind generator by assessing the conditional value-at-risk (CVaR). In the upper level, the profit is maximised by selecting the proper bidding strategy based on double-auctioned market mechanism. To check the effectiveness of the proposed strategy, Monte Carlo simulation and scenario-based approach are used to generate the scenarios considering the random line outages, generator outages and load variations. The CVaR is used as a risk assessment tool for the uncertainties that would inadvertently affect the profit of the GENCOs. The proposed approach is applied to the modified IEEE 30-bus system to show the effectiveness of the proposed model and its impact on the bidders and suppliers.
EROSION OF TUNGSTEN-NITRIDE AND IRON-TUNGSTEN SURFACES UNDER DEUTERIUM

Nuclear Fusion. The holy grail of clean energy production. Still a lot of physical and technical issues need to be solved in order to use nuclear fusion as a future energy source. One of the most challenging parts is the coating of the reactor vessel, which faces the ultra hot plasma. The erosion of material compositions, used in nuclear fusion devices as a first boundary between the plasma and the reactor vessel, is therefore a topic of current research. Current experimental nuclear fusion devices with a full tungsten divertor uses nitrogen seeding to reduce the power load on highly exposed surfaces, by enhanced radiative cooling. The formation of tungsten-nitride (WN) layers, caused by nitrogen (N) ion implantation and their erosion due to deuterium (D) and nitrogen (N) bombardment is therefore of particular interest. For future fusion devices low activation steels (e.g. EUROFER) are considered for recessed areas. Preferential sputtering of tungsten-containing steels (FeW) could lead to a surface enrichment with tungsten (W), thereby reducing the erosion yield and increasing the lifetime of these components. A profound understanding of the interaction of D ions with WN and FeW surfaces is hence highly desirable. In the course of this work W and WN surfaces, as well as Fe and FeW surfaces were bombarded with mono energetic D particles to measure sputter yields at high fluences (≈ 10 D/m), using a highly sensitive quartz crystal microbalance technique (QCM) under well defined laboratory conditions. An existing ECR ion source was not able to provide sufficient high ion fluxes to do these measurements in an acceptable amount of time, so a new measurement setup needed to be developed. The use of a sputter gun as an ion source increases the ion flux by a factor of about 250, up to 2.7 · 10 D/m/s and makes high fluence measurements feasible. Measurements with WN surfaces show a strong dependence of the observed mass change rate on the bombarding D fluence. The mass loss is initially higher, compared to pure W surfaces, and drops with increasing fluence, reaching the same mass removal rate as for pure W. At a kinetic projectile energy of 1000 eV/D a fluence of about 6 ·1022 D/m is necessary, while at 500 eV/D the required fluence is with about 2 · 10 D/m lower. Comparisons with dynamic sputtering calculations with SDTRIM.SP indicate a preferential removal of N and therefore a W enrichment of the surface. The interaction of D projectiles with FeW surfaces, with 1.5 at. % W, show at low fluences a mass removal rate close to the value of pure Fe. With increasing D fluence a reduction of the mass removal rate is observed. At a kinetic projectile energy of 1000 eV/D and after a bombarding fluence of 2 · 10 D/m a nearly steady state mass removal rate can be seen. At 250 eV/D even after a fluence of about 3.5 · 10 D/m no steady state conditions of the mass removal rate is found, a fact, which indicates a continuous surface enrichment of W.
I MPACT OF J UICE F ACTORY S PENT W ASH ON T HE G ROWTH AND P IGMENT C ONTENT OF L ABLAB PURPURES S WEET . (L.)

SUMMARY Juice factory spent wash effluent discharged as wastewater, contains various toxic chemicals that contaminate water and soil. It may affect the common crops if it is used for agricultural irrigation. Toxic nature of juice factory effluent is due to the presence of high amounts of organic and inorganic chemical loads and its high acidic in nature. The paper deals with the effects of untreated juice factory spent wash, on growth and pigments content of Lablab purpures Sweet. (L.). The Lablab purpures Sweet. (L.) is a commonly used legume crop in Tamil Nadu. Seeds were selected and surface-sterilized with 0.1% HgCl2 for 2 minutes and washed with distilled water thoroughly. They were treated with different concentrations (5-100%) of effluent. The germination percentage growth (shoot and root length), fresh weight, dry weight and pigment content of the plants were investigated. The results revealed that the germination characters, root and shoot length, fresh and dry weight and pigment content increased upto 5% concentration and there after decline in higher concentrations of spent wash effluent.
Modeling the Population Demographics & Viability of Imperiled Guzmania monostachia Populations

Guzmania monostachia is a large, long-lived bromeliad whose leaves grow in a rosette pattern and is native to the Americas, but endangered in Florida due to damage caused by the invasive weevil Metamasius callizona. Each G. monostachia rosette can reproduce sexually via flowers or asexually by producing clonal offshoot rosettes. We model the population dynamics and demographic structure of a G. monostachia population using a Lefkovitch matrix model where each state represents a demographic class of rosettes. Model analysis over a range of uncertain parameters show the conditions under which a G. monostachia population is viable in the absence and presence of M. callizona, and the expected demographic structure under those conditions. In particular, our analysis illustrates that proportional reductions in survival have a qualitatively stronger impact on population viability than proportion reductions in clonal fecundity.

Bacterial Community Dynamics and Influencing Variables during Composting with Different Initial Raw Materials (Pig Manure and Tea Waste)

This research was carried out to determine the structure dynamics and shaping factors of bacterial community during agricultural waste composting with pig manure or tea waste. Bacterial community structure was determined by Denaturing Gradient Gel Electrophoresis (DGGE). Redundancy analysis was used to estimate the relationship between bacterial community structure and environmental parameters. Results showed that Firmicutes, Proteobacteria, Acidobacteria , and Bacteroidetes were the dominant bacterial phyla and varied in samples with different initial materials. Anoxybacillus toebii, Keratinibaculum paraultunense, Peptoniphilus methioninivoras , were remarkable observed during the cooling and maturation stages of pig manure piles. While Clostridium bytyricum, Halanaerobium salsuginis were widely distributed during the whole composting process for tea waste. Redundancy analysis indicated that EC, pH, TN, and TOC showed predominant influence on the bacterial community structure. Significant amounts of the variation (47.0%) of community structure were explained by those parameters. These parameters might be the most responsive ones influencing the succession of bacterial communities during agricultural waste composting for pig manure and tea waste.
Increasing and Validating the Safety and Reliability of Cyber-Physical Systems

Cyber-physical systems (CPS) like production facilities, medical devices, and modern cars play an increasingly significant role in the economic context but also in every-day life; catchphrases like “Industry 4.0” and “Mobility of the Future” are on everybody’s mind. Manufacturers and operators of such systems are highly interested in investigating and ensuring the safety and reliability of their systems. The security researchers of AIT Austrian Institute of Technology’s research field “Dependable Systems Engineering” (DSE) deal with the challenge of increasing the safety and reliability of cyber-physical systems since many years. The team actively engages interesting problems in both, the scientific - and production domains together with key industry partners. In this way, they not only drive scientific progress in their field of study but also keep their eyes on the practical applicability of their solutions. With this goal in mind, the DSE’s researchers and engineers develop tools and methodologies to address questions regarding Safe and Secure Co-Engineering. Examples include safe and secure reference architectures; methods for model-based analysis of safety-critical systems; automated test case generation; and real-time monitoring of complex systems. The group’s experts also contribute to the development of industry standards, e.g., ISO26262.
Strain Sensitivity of Li-ion Conductivity in β -Li 3 PS 4 Solid Electrolyte

Strain is present at the interfaces of solid electrolytes with the cathode and the anode in solid-state batteries due to interfacial reactions and due to volumetric expansion and contraction of the electrodes during battery charging and discharging cycles. This work quantiﬁes the eﬀect of elastic strain on Li-ion diﬀusion in a model solid electrolyte, β -Li 3 PS 4 , by using ab initio molecular dynamics (AIMD). We ﬁnd that the strain tensors which compress the c axis ( + 2% a - b , − 2% a - c , − 2% b - c , − 2% isotropic) increase the Li-ion diﬀusivity, and the strain tensors which stretch the c axis ( − 2% a - b , + 2% a - c , + 2% b - c , + 2% isotropic) reduce it. Ionic conductivity increases by 2–14-fold with a reduction in activation energy for c -axis compressive strains and decreases by 1–14-fold with an increase in activation energy for c -axis tensile strains at room temperature. The c -axis compression increases disorder in the lattice and promotes jumps along all migration pathways. In particular, the Li 4 c site occupancy increases from about 3% to 6% (at 500 K), thus creating more vacancies at otherwise fully occupied and bottleneck 8 d and 4 b sites. The c -axis compression also reduces the distance between the 8 d and 4 b sites, thus increasing Coulomb repulsion between these sites. Increased Coulomb repulsion can destabilize Li at the 8 d and 4 b sites, promoting reduced occupancy and increased diﬀusivity associated with these sites. The results show that elastic strain can promote Li disorder and superionic conductivity, with an eﬀect on Li-ion diﬀusion comparable to that of chemical substitution, and is important to consider for an accurate understanding and prediction of the solid-state Li-ion battery interface properties.
BL5U at UVSOR‐II for Three‐dimensional Angle‐resolved Photoemission Spectroscopy

BL5U at UVSOR‐II has been reconstructed in 2004’s for three‐dimensional angle‐resolved photoemission (3D‐ARPES) study on solids and surfaces. The beamline is equipped with a helically/linearly polarized undulator, an old‐type monochromator named as SGM‐TRAIN designed in 1995’s, and a new photoemission end‐station. Since their performances are insufficient to study anomalous electronic/magnetic properties on materials in recent years, we reconstructed the beamline for a high‐resolution study as follows; (1) The manipulation of the pre‐focusing mirror was updated to a high‐precision system controlled by pulse‐motors. (2) The entrance slit with water cooling system was adopted for avoiding the heat load from undulator radiation. (3) The SGM‐TRAIN was re‐arranged to the optimum condition to the undulator light. (4) The free tuning program of the undulator gap and monochromator‐control systems was introduced. Due to the reconstructions, we successfully improved the throughput intensity and energy resolution of.
Angles, Majorization, Wielandt Inequality and Applications

In this thesis we revisit two classical definitions of angle in an inner product space: real-part angle and Hermitian angle. Special attention is paid to Krein’s inequality and its analogue. Some applications are given, leading to a simple proof of a basic lemma for a trace inequality of unitary matrices and also its extension. A brief survey on recent results of angles between subspaces is presented. This naturally brings us to the world of majorization. After introducing the notion of majorization, we present some classical as well as recent results on eigenvalue majorization. Several new norm inequalities are derived by making use of a powerful decomposition lemma for positive semidefinite matrices. We also consider coneigenvalue majorization. Some discussion on the possible generalization of the majorization bounds for Ritz values is presented. We then turn to a basic notion in convex analysis, the Legendre-Fenchel conjugate. The convexity of a function is important in finding the explicit expression of the transform for certain functions. A sufficient convexity condition is given for the product of positive definite quadratic forms. When the number of quadratic forms is two, the condition is also necessary. The condition is in terms of the condition number of the underlying matrices. The key lemma in our derivation is found to have some connection with the generalized Wielandt inequality. A new inequality between angles in inner product spaces is formulated and proved. This leads directly to a concise statement and proof of the generalized Wielandt inequality, including a simple description of all cases of equality. As a consequence, several recent results in matrix analysis and inner product spaces are improved.
