ABSTRACTEmbedded systems constitute the class of computers that presentthe most significant volume and are increasingly present ineveryday life. The main element of these systems is the processor,which can be found in discrete form, represented by a physicalcomponent, or cores, as used in programmable logic devices.Processors of the same architecture share the same instructionset but may differ in the organization’s implementation. RISC(Reduced Instruction Set Computer) is the class of architecturesthat favors a simple, reduced instruction set. RISC-V is an exampleof such architecture, which consists of an initiative by academiaand industry to be open and free, aiming for easy and optimizedimplementations. However, due to the recent disclosure of itsfeatures and specifications, RISC-V needs more reference materialfor digital and embedded system designs. This work proposesthe RVSH, a simple RISC-V processor for teaching and researchactivities. The implementation aims to allow the adoption of thisarchitecture in topics such as digital systems, computer architecture,microcontrollers, and embedded systems design.

Performance and cost-effectiveness of air disc brakes and air drum brakes for truck semi-trailers in different road and speed conditions
Authors: Ampadu Vincent Michael , Alrejjal Anas , Ksaibati Khaled
Published: May 2023

This study uses TruckSimTM to model disc brakes and drum brakes on a fully loaded truck semi-trailer to study the performance of each brake type as downgrades and speeds vary. The brake performance is measured based on braking distance. A simplified economic comparison based on life cycle cost analysis to determine which road and vehicle conditions give rise to the cost-effectiveness of disc brakes is performed. The studies suggest that disc brakes shorten braking distances by 10-20%. They also suggest that the percentage reduction in braking distance as speed increases and downgrade gets steeper is approximately 12-19%. Evidence is provided that trucking companies operating their vehicles in steep terrain and at high speeds with disc brakes could benefit from 12-80% in long-term cost savings. Finally, at the societal level, by preventing crashes arising from rear-end collisions and runaway truck incidents, disc brakes save at least $649 million annually.
Factors of the capital structure of maritime sector companies for increasing business value - theoretical approach
Authors: Puleikiene Kristina , Svazas Mantas
Published: May 2023

The global world and individual countries, which are influenced by the economic, financial crises, and pandemics that occur in one way or another, have a major impact on business and its performance. Declining consumption, disrupted settlements, limited or unavailable sources of finance, and other economic and financial reasons may cause business failures. Efficient and rational financial management is crucial for companies to survive and operate successfully under various conditions of the economic cycle, especially in times of crisis. It can be argued that, under modern conditions of market economy, making economically sound decisions about the structure of funding sources is one of the most important tasks for business companies, since the formation of a capital structure establishes the company's ability to maximise its return, manage risks effectively, and operate successfully in a competitive environment to meet the needs of a wide range of stakeholders. The maritime sector is strategically important and economically significant for any country. Companies in this sector make a significant socio-economic contribution across the entire state. When forming the capital structure in the maritime sector companies, certain exceptions are encountered since the operation of these companies requires a large amount of borrowed capital. Increasing the business value of maritime sector companies has a positive meaning nationally and internationally.
Investigating snowplow-related injury severity along mountainous roadway in Wyoming
Authors: Haq Muhammad Tahmidul , Reza Imran , Ksaibati Khaled
Published: May 2023

Snow removal and deicing using snowplow trucks assist transportation agencies to enhance roadway safety and mobility. However, due to slower travel speeds during these operations, motorists often end up in crashes for poor visibility and disturbance of the snow. Despite the risk associated with snowplows, no previous study was found that exclusively investigate the factors associated with injury severity in snowplow-involved crashes. Therefore, this paper presents an extensive exploratory analysis and fills this knowledge gap by identifying the significant contributing factors affecting the occupant injury severity from the aspects of crashes with snowplow involvement. The study utilized eleven years (2010-2020) of historical snowplow-related crash data from Wyoming. Both the binary logit model and mixed binary logit model were developed to investigate the impacts of the various occupant, vehicle, crash, roadway, and environmental characteristics on the corresponding occupant injury severity. As one of the important findings from this research concludes that other vehicle drivers are more responsible than snowplow drivers contributing to more severe injuries in crashes involving snowplows. Recommendations suggested based on the modeling results are expected to help transportation agencies and policymakers take necessary actions in reducing snowplow-involved crashes by targeting appropriate strategies and proper resource allocation.

Authors: Foria Federico , Calicchio Mario , Moretti Laura , Loprencipe Giuseppe
Published: May 2023

The tunnel industry has started focusing on the maintenance and management challenges of an existing infrastructure. It is an urgent matter in industrialised countries, where the stakeholders’ attention is increasing at a fast pace considering the incidents and the disruptions caused by improper monitoring and maintenance. This paper presents an innovative methodology to survey and inspect existing railway tunnels through multi-dimensional mobile mapping systems. The proposed approach belongs to the digital strategies for infrastructure maintenance. An integrated multidimensional survey system (ARCHITA) allows for collecting information necessary for the diagnostics of a structure with non-destructive tests. Linear cameras, thermographic cameras, and ground-penetrating radars acquire data to be digitalised and manipulated in different IT environments. The results, in terms of the collected data on structural defects, allow for a new approach for the Management and Identification of the Risk for Existing Tunnels (MIRET). The innovative approach aims at a smart integration of information and models for the Facility Management of the transport system. The workflow for the digitalisation and diagnosis from mobile mapping data has been implemented on two 40km-long metro tunnels.

This study aimed to investigate whether teacher candidates’ learning approaches and engagement levels predicted their achievement in the Curriculum Development course in a hybrid course in Turkey. This study was designed according to RASE (Resources/Activity/Support/Evaluation) model. In this study, data were collected from 129 teacher candidates through the ‘Learning Approaches Questionnaire’ and ‘Engagement Questionnaire’. The achievement scores of teacher candidates were obtained at the end of the semester according to their course grades. To answer the research question, the Multiple Linear Regression analysis was employed. The results of the study showed that while the deep learning approach of teacher candidates was significantly and positively related to engagement variables, the surface learning approach was related to engagement variables negatively. However, it was revealed that the surface learning approaches and behavioral engagement of teacher candidates significantly predicted the achievement in the hybrid Curriculum Development course. It can be concluded that the learning environment is important for learning outcomes. It can be suggested that besides providing different active learning opportunities, teacher candidates should be assessed in accordance with the level of applications conducted in the hybrid learning course to improve deep learning and all types of engagement levels.

Review ini bertujuan untuk menjelaskan mengenai pengaruh perubahan struktur pati akibat dari proses oksidasi pati menggunakan ozon terhadap sifat fisik pati, seperti daya kembang, kelarutan, viskositas, dan freeze-thaw stability. Pati alami yang selama ini banyak digunakan sebagai bahan pengental, pengisi, pembentuk gel pada berbagai produk memiliki banyak kelemahan, seperti kelarutan terbatas, viskositas tidak seragam, dan tidak tahan suhu tinggi. Oleh karena itu dibutuhkan modifikasi pada pati alami untuk mendapatkan pati dengan karakteristik yang diinginkan. Ozon merupakan salah satu zat oksidan yang dapat digunakan untuk memodifikasi pati melalui proses oksidasi. Selama proses oksidasi, terjadi perubahan gugus hidroksil dari molekul pati menjadi gugus karbonil dan karboksil sehingga berpengaruh terhadap peningkatan daya kembang, kelarutan, dan freeze-thaw stability serta penururnan viskositas pati.

L’éloge du fleuve. La Seine et ses bords, par C. Nodier entre album pittoresque et mémoire géographique
Authors: Sukiennicka Marta
Published: May 2023

The article examines the question of the authorship and generic classification of La Seine et ses bords (1836). This work is commonly misattributed to Charles Nodier, but the most likely author is Alexandre Mure de Pélanne, who in 1835 published a similar essay on the Saône River. The comparison of both works shows a clear difference in their perspectives: La Saône et ses bords, with an emphasis on the his- torical context, meets the generic criteria of album pittoresque (picturesque album), whereas a focus on topography and hydrology of La Seine et ses bords brings it closer to the genre of mémoire géographique (geographical memoir). The scientific scope of La Seine et ses bords also distinguishes it from Nodier’s and Taylor’s Voyages pittoresques et romantiques dans l’ancienne France, the most famous cycle of Romantic journeys through France.
Multichannel modulation of depolarizing and repolarizing ion currents increases the positive rate‐dependent action potential prolongation
Authors: Cabo Candido
Published: May 2023

Prolongation of the action potential duration (APD) could prevent reentrant arrhythmias if prolongation occurs at the fast excitation rates of tachycardia with minimal prolongation at slow excitation rates (i.e., if prolongation is positive rate‐dependent). APD prolongation by current anti‐arrhythmic agents is either reverse (larger APD prolongation at slow rates than at fast rates) or neutral (similar APD prolongation at slow and fast rates), which may not result in an effective anti‐arrhythmic action. In this report we show that, in computer models of the human ventricular action potential, the combined modulation of both depolarizing and repolarizing ion currents results in a stronger positive rate‐dependent APD prolongation than modulation of repolarizing potassium currents. A robust positive rate‐dependent APD prolongation correlates with an acceleration of phase 2 repolarization and a deceleration of phase 3 repolarization, which leads to a triangulation of the action potential. A positive rate‐dependent APD prolongation decreases the repolarization reserve with respect to control, which can be managed by interventions that prolong APD at fast excitation rates and shorten APD at slow excitation rates. For both computer models of the action potential, ICaL and IK1 are the most important ion currents to achieve a positive rate‐dependent APD prolongation. In conclusion, multichannel modulation of depolarizing and repolarizing ion currents, with ion channel activators and blockers, results in a robust APD prolongation at fast excitation rates, which should be anti‐arrhythmic, while minimizing APD prolongation at slow heart rates, which should reduce pro‐arrhythmic risks.
Assigning Property Rights to Scarce Resources when Individual Wealth Levels are Observable
Authors: Kim Jeong-Yoo , Lee Jeho
Published: May 2023

In this note, we consider how to allocate property rights to scarce resources when agents have budget constraints. Each individual’s wealth level is often observable to the state, although the individual subjective valuation for the resource is hardly known to the state. Under this situation, we mainly compare the efficiency of allocations under two assignment mechanisms; (i) the random assignment with resale and (ii) priority assignment to the poorest with resale. We show that the latter is more efficient than the former. If the mass of goods to be allocated is large enough, the latter can achieve social optimum.

is required in controlling processing parameters for the extrusion processing of polymer melts. A new method, the so-called ramp test, is investigated in this study to obtain the steady-state shear viscosity with a closed cavity rheometer (CCR). To verify the method and the accuracy of the CCR data, three commercial polyolefin polymers, a low-density polyethylene (LDPE), a linear low-density polyethylene (LLDPE), and a polybutadiene (PBD), were used as model systems. Measurements of the magnitude of the complex viscosity

were compared with the steady-state shear viscosity data obtained by capillary rheometer and CCR. Further, time–temperature superposition master curves of the magnitude of the complex viscosity and steady-state shear viscosity obtained by CCR were developed for LLDPE and PBD. The influence of the cavity sealing on the instrument’s accuracy to obtain the steady-state shear viscosity was investigated using the finite element method simulations. Thus, it was shown that the ramp test performed by CCR is a practical method to determine reliable and reproducible data of the steady-state shear viscosity within a wide range of temperatures (T = 50–180°C) for low and high viscous materials (

The present study investigated the toxic action of acrylamide (ACR) and the abrogative effect of aqueous propolis extract on ACR-induced toxicity in male albino rats. Forty adult male albino rats were randomly divided into four groups and administered the treatment doses orally by gavage. Control, treated with a physiological solution (5.0 ml/rat). ACR-treated group, treated with ACR 25 mg/kg. ACR + propolis, treated with 25 mg/kg ACR + 100 mg/kg propolis. Propolis-treated group, treated with 100 mg/kg. The treatment period was 28 days, the treatment doses were administered orally using a gavage stomach tube. The results showed that the presence of ACR increased (P < 0.001) the level of liver enzymes alanine aminotransferase (167.2 vs 90.15) and aspartate aminotransferase (120.66 vs 41.52) in the liver tissue serum and lipid peroxidation products (80.11 vs 39.3); also, it decreased (P < 0.001) the total capacity of antioxidants (113.4 vs 189.41) compared to the control group. The histological analysis of the kidney revealed alterations induced by ACR, including atrophy, necrosis, renal glomeruli atrophy, tubular necrosis, enlargement of the glomeruli, hemorrhage, and edema surrounding the blood vessels. Also, the results showed that the rats treated with propolis improved liver and kidney functions because of propolis’s efficiency against the harmful effects of ACR. Moreover, the histological examination of the liver tissue revealed negative changes, with focal necrosis in hepatocytes. Microscopic examination showed tubular necrosis within the seminiferous tubules, sloughing, and desquamation of sperm cells into the lumen. Also, an infiltration of protein substances between the tubules and degenerative vacuolar changes between sperm cells was observed. The renal, hepatic, and testicular tissues appeared almost similar to the control group, except for some minor changes. This study proved that feeding the rats with propolis reduced these pathological effects and restored the tissues to a normal state. It is concluded that using propolis with ACR significantly reduced the biochemical and histological damage caused by ACR, and recommends using propolis as a cytoprotective agent against pathological toxicity of ACR.
