Sizing of the Propulsion System for a Heavy-Duty Fuel Cell Commercial Vehicle

This paper presents a methodology for the sizing of a heavy-duty fuel cell commercial vehicle. The parameters scanning model and the long-term stochastic drive cycle are adopted for this proposed sizing framework. The dynamic programming algorithm is employed as the energy management strategy to assess the performance of sizing. The efficacy of this framework is evaluated, and a detailed analysis for the hydrogen consumption is given in the results. In addition, a prediction analysis based on the price performance of the next decade is also given in this work.

How did the Sarbanes–Oxley Act affect managerial incentives? Evidence from corporate acquisitions

We examine the impact of incentive compensation on the riskiness of acquisition decisions before and after the passage of the Sarbanes–Oxley Act (SOX). Before SOX, equity-based compensation was positively related to changes in risk around acquisition decisions, but this relationship weakened after the introduction of SOX. The drop in post-SOX acquisition-related risk stems from how managers respond to compensation-based incentives in the new regulatory environment. We show that executive stock options and pay-risk sensitivity drive post-SOX managerial responsiveness to risk-taking incentives. We also document a post-SOX value-enhancing effect on long-term stock-price performance and total factor productivity through these same incentive compensation mechanisms. The results are robust to selection bias, simultaneity, measurements of risk, and the definition of incentive compensation.

Moderasi Perbedaan Opini terhadap Faktor-Faktor Kinerja Harga Saham pada Perusahaan Sektor Pariwisata Saat Pandemi Covid-19

An uncertain and crisis-prone economy has an impact on the capital market in Indonesia. This study aims to analyze the effect of profitability, leverage , liquidity and differences of opinion on stock price performance and the role of investors' differences of opinion in moderating the effect of profitability, leverage , and liquidity on stock price performance. The population in this study is the tourism sector companies listed on the Indonesia Stock Exchange. The number of research observations was 136 observations. Data analysis used moderated regression analysis. The results of the study of profitability and leverage have a positive effect on stock returns . Leverage which has no significant effect on stock returns . The results of this study also do not prove that differences in investor opinions moderate the effect of profitability, leverage , liquidity on stock price performance, possibly because tourism sector companies are not very favored by investors so that stock prices do not move much during the Covid-19 pandemic. Keywords: Profitability; Leverage; Liquidity; Stock Price Performance.

Effect of Materials Content on Dimensional Stability, Nano Roughness and Interfaced Morphology for Virgin or Recycled Polypropylene Based Wood Composites

The compositions of mango wood-polypropylene composites (WPCs) are formulated, with different compositions of virgin polypropylene (PP) or recycled PP, mango wood waste and a coupling agent. The compositions are fabricated via melt extrusion compounding pursued by injection hot molding. The tests of the prepared compositions are carried out for, water absorption, thickness swelling, surface properties at a nano-scale and interfaced morphology. Comparative study of WPCs composition has done on respective properties. All processing variable conditions are constant for different compositions. The recycled PP based wood composites with or without the coupling agent possessed superior properties in comparison to virgin PP based composites. FESEM images show that coupled composite is having the better bonding strength and smoothness along with a higher dimensional stability in comparison to none coupled composite. Future endeavor should be focused on optimizing the composition of reinforcement wood and recycled plastics matrix according to intended application. The quality of WPCs can also be improved with the co-ordination of latest development in technology and processing technique relevant to them. WPCs study supports “turning waste into something useful”. This provides the mileage in price performance ratio and also the product’s environmental footprints to be adjusted to suit the products application.

DEBT EQUITY AND SHARE PRICE PERFORMANCE OF MANUFACTURING COMPANIES LISTED IN NIGERIA

This study examined the impact of debt equity ratio on the share price performance of manufacturing firms listed in Nigeria between 2010 and 2019. The study adoptedan ex-post facto research design. A sample size of fifteen (15) listed manufacturing firms was used while panel regression models estimated using fixed effect model and random effect model, while the result of the Hausman test was utilized to select the appropriate model between fixed effect model and random effect model.The findings of the study reveals that the total debt to equity ratio is negative and significant influence on performance of share price {Coef. = -0.009 P-value > 0.05}. Return on Assets is also seen to be positive and significantly influence the performance of share price of listed manufacturing firm in Nigeria {Coef = 2.428 P-value = 0.000}. However, Size of firm {Coef. = -0.019 P-value = 0.344} is seen to have negative but insignificant effect on the performance of share price. The study therefore recommended that firm manager should cautious while using debt finance. Firm manager should consider the consequences of debt finance before making capital structure decision. They are supported to identify the optimum debt level and ensure that they are no use excessive amount of debt in capital structure.
