10 In transit systems, automatic fare collection systems (AFCs) are widely used. Passengers are 11 often required to use their smart cards only when entering stops, so their destination is 12 unknown. Methods have been proposed for addressing the problem, but most of those require 13 network-level AFC data. The problem remains unresolved when only one line's AFC data is 14 available. This paper tries to solve this issue for specific applications, like crowding-related 15 problems such as calculating perceived travel times. In our method, rather than minimizing 16 errors, the model is constructed so that desirable errors are produced to counter undesirable 17 errors. The task is accomplished by employing an imbalanced binary class classification 18 based on thresholding for each stop. A classification indicates whether a passenger is 19 alighting or has already alighted at the study or previous stops. Although the model may 20 produce incorrect predictions for a particular stop, it will be adjusted to make a deliberate 21 error: for every incorrect prediction of alighting, there will be a few incorrect predictions of 22 not alighting. Using this technique, we estimate how many passengers are on board the bus. 23 Our model has the functionality of an Automatic Passenger Counting (APC) system when 24 the line does not have one. 25

9 Dependence on private cars has led to numerous problems, where AVs could be a potential 10 solution. Pooled service, however, could be a much bigger step towards sustainable transportation. 11 This paper presents a modal shift analysis emphasizing socio-economic, travel characteristics and 12 their interaction for a sample of private car users in Tehran. A stated preference survey was 13 designed in 2021 exclusively for the research purposes, and 491 valid questionnaires were 14 gathered. One of the main contributions is considering the impact of the number of persons in 15 shared autonomous vehicle with pooled service (SAVWPS). Estimation results of discrete choice 16 model reveal that, high-income respondents, owning a personal car and being a man decrease the 17 likelihood of modal shift to SAVWPS. A negative impact is also observed for travel time, travel 18 cost, waiting time and number of persons in SAVWPS. A significant systematic heterogeneity is 19 observed in the interaction effect of travel time and dissatisfied respondents with internet taxis due 20 to the pandemic. Considering this taste variation, a lower travel time in SAVs could increase the 21 modal shift likelihood among these travelers. The findings could help transportation decision-22 makers identify the factors affecting modal shift to SAVWPS to achieve a more sustainable 23 transportation system.

In this study, calendering process of an Oldroyd 4-constant model with the non-linear slip condition is presented. The fundamental laws are used to formulate the flow equations and then are simplified under lubrication approximation theory. We introduced the stream function to eradicate the pressure gradient and then numerically solved the final equations using the "bvp4c method" to determine the stream function and velocity profiles. The pressure gradient, pressure, and mechanical quantities of calendering operations are computed using the Runge-Kutta 4 th -order approach. Using a variety of graphs, it is discussed how the slip, Hartmann number, and material parameters of an Oldroyd 4-constant fluid affect the velocity, pressure gradient, and other associated characteristics of calendering. The results reveal that on comparing to the no-slip situation, the pressure distribution inside the calender and the length of contact decreases with increasing slip parameter values. On the other hand, the Hartmann number is responsible to enhance pressure. Furthermore, a reduction is observed in final sheet thickness with increases the values of the slip parameter ( Kn ). The force and power are the decreasing function of 1 , conversely, these quantities increase with enhancing the values of leave off distance ( ).

The analysis of surface waves in an initially stressed homogeneous magneto-elastic material with voids source, corrugated and impedance boundary conditions influenced by an applied mechanical force on the surface of the material is the hallmark of this investigation. The framework of the study also encompasses the use of normal mode solution approach, non-dimensionalization of the resulting equations of motion and grooved boundary conditions occasioned by the modeled problem. The distribution of the displacement components, normal and shear stresses, volume fraction fields were analytically and graphically presented using Mathematica Software for a particular chosen material which hitherto demonstrates the effects of the contributing physical quantities on the material. The initial stress, voids source, and Mechanical force have remarkable effects to the behavior of the distribution profiles on the material. Increased influences of the magnetic fields decrease the amplitude of the distribution functions whereas impedance parameter induced a mechanical like resistance to the distributions. Thus, this work should prove useful in understanding studies involving seismology. Also, researchers in the fields of Geophysics, Mathematics of waves, Material Sciences, amongst others should be able to find the work helpful.

. Communication networks can be represented as graphs, where vertices represent network nodes and edges represent connections between them. Various graph theory parameters, such as connectivity, toughness, tenacity, binding number, scattering number, and integrity, were presented to assess the vulnerability of networks. Calculating the values of these vulnerability parameters can be challenging, particularly for certain classes of graphs, such as Generalized Petersen Graphs ( G P G ), due to their diverse structures. This paper establishes upper and lower bounds for the tenacity of G P G . We demonstrate a lower bound of 1 for the tenacity ( ( ) ) , ( k n G P G T ), across all values of n and k. Additionally, we explore the tenacity values of G P G and present a general upper bound for the tenacity value in this graph type. By using the relationship between the tenacity parameter and the connectivity ( ) G κ and toughness ( ) G t parameters, we also update some theorems related to the connectivity and toughness of GPG .

: This communication presents the novel triple-band monopole antenna in the shape of a traditional patch antenna, which is made up of a rectangular radiator with a slot and double stub loaded defected-ground structure. The antenna works on the triple bands of 2.4, 3.5, and 5.8 GHz , respectively, and it is made on the standard FR-4 dielectric material. The volume covered by the antenna is relatively small, which is 20 x 20 x 1.6 mm 3 or 0.16 x 0.16 x 0.0128 λ 30 ( λ 0 is the wavelength in free space at 2.4 GHz ). The data obtained from the measurements prove that the antenna has bandwidths of 100 MHz at 2.4 GHz, 100 MHz at 3.5 GHz, and 300 MHz at 5.8 GHz bands, respectively. It has maximum gain values of 2.91, 0.5 , and 5.5 dBi , and the antenna works efficiently on the proposed WLAN and WiMAX frequency bands. It can be posited that the suggested antenna system is a suitable option for WLAN and WiMAX band wireless applications.

Numerical study is conducted to execute the analysis of rotational stagnation point second-grade liquid flowing over the spiraling rotatory disk. Heat transmission analysis is accounted. The problem is formulated in the coupled partial differential equations forms which are later simplified in view of similar variables. The Keller-Box (KB) procedure is adopted for the execution of numerical solutions. The involved parameters influences on the velocity and temperature profiles are presented and interpreted. The skin-frictions and Nusselt number are reported in the forms of numerical data. The present results are verified through the comparison with already available material in the literature. This study addressed that the thickness layer of boundary augmented against the incrementing viscoelastic and rotational parameters. Both rotational and viscoelasticity resist the temperature. The rotational parameter rises radial skin-friction and heat transmission rate while diminishes the swirl skin friction.
