This study investigates the impact of corporate governance (defined as companies' ownership structure and board of directors' characteristics) on cash holdings in the context of Oman. This study leverages a quantitative panel pooled regression on a dataset of Omani non-financial firms from 2009-2015. The findings of this study are generally in line with the predictions of Agency Theory and Mentoring and Busyness Hypotheses. The analysis demonstrates that a large stockholder size has a significant positive relationship with cash holding. Meanwhile, a positive (but insignificant) relationship was also found between institutional ownership and cash holding. Furthermore, state ownership was found to exhibit a significant negative relationship with cash holding. In terms of the board of directors' traits, this study's findings suggest that board sizes have a positive (but insignificant) relationship with cash holding. Furthermore, busy and independent boards were found to have a significant positive relationship with cash holding. The above findings suggest that boards with such traits are less effective in providing oversight on managers' actions, which would then increase Omani non-financial firms' cash holdings.

Thermal flows inside a laser printer are affected by generated heat from a fuser and boards. Thus, the effect of fans has been investigated to control the thermal flows and behaviors of toners. In order to analyze the phenomena experimentally, a PIV (Particle Image Velocimetry) has been used, and then the flow inside the printer has been predicted by the CFD (Computational Fluid Dynamics) in this study to determine the efficient flow distribution by an optimum design of the printer. The determined optimum design has been confirmed by the developed PIV technique so that the efficiency of the laser printer can be improved by the proposed design.

This paper proposes a new methodology for the estimation of impedance characteristics, which is one of the important issue in the power distribution network design of printed circuit boards. The modeling process of the proposed method divides the power distribution network into uniform segment, and each segment is modeled by distributed RLC transmission lines. Then, for the efficient computation of impedance characteristics in frequency domain. the proposed method uses a model-order reduction method.

The study aims to investigate factors that determine dividend payout policy using 336 non-financial firm year observations covering the period 2005 to 2016 in Malaysia. We found a significant positive relationship between corporate board size, board members average age, board tenure and dividend payout policy. We also found a strong negative effect and statistically insignificant relationship of board diversity, board independence, CEO duality and dividend payout policy. Additional, financial leverage has a negative effect on dividend payout policy. It is also noticed that firms with diverse boards are more likely to pay dividends and tend to pay larger dividends than those with non-diverse boards. Our results suggest that board diversity has a significant impact on dividend payout policy. Impact of board diversity on dividend payout policy is particularly conspicuous for firms with potentially greater agency problems. Our findings are consistent with the argument that corporate board traits enhancement positively affect the dividend payout policy which is beneficial for shareholders. This study offers useful insights into the current global debate on board traits and its implications for firms. The dividend payout policy signals good news to investors. Corporate board traits and firm's financial decision are the factors that disrupt the dividend decision.

This research extends the literature on the effect of board characteristics and ownership structure on audit fees; these factors affect the firm's agency costs and how the auditor assesses various risks, hence the audit efforts and fees. The paper introduces political connections as a determinant of audit fees for the first time in Jordan, where the political connection is prevalent and affects decision making on the Jordanian boards. The sample consists of 109 manufacturing and service firms listed on the Amman Stock Exchange (ASE) over the years 2012-2019. Data is obtained from the ASE and the company's annual reports. Board characteristics are measured by board size, independence, leadership duality, meetings frequency, political connections, and audit committee. Ownership structure was measured by concentration, foreign ownership, and Institutional ownership. The study hypotheses were tested by using Generalized Least Squares regression. The Findings showed that larger boards, politically connected firms, and firms with leadership duality are more likely to pay higher fees. Besides, Firms with greater foreign ownership pay less fees, whereas the rest of the variables are insignificant. Results suggest that political connections play a major role in determining audit fees; this provides a recommendation to policymakers in Jordan to reconsider regulations regarding political connections.

This study investigates the impact of gender diversity on the board of directors on corporate intellectual capital (IC) disclosure in Indonesia. For the study purpose, the sample was divided into two sections, i.e., companies with large capitalizations and companies with small capitalizations. A paired T-test was used to observe significant changes in the disclosure level between period and type of firm. Using linear regression analysis, the influence of gender diversity and other variables on IC disclosure was examined. The findings show that IC disclosure varies for large and small companies. The level of IC disclosure in large companies was stronger than in small companies. The results of the multivariate analysis showed that the profitability, leverage, ownership, and type of business of the company significantly affect IC disclosure. For companies with large capitalization, the presence of women directors on corporate boards or gender diversity on corporate boards does not impact IC disclosure. This is because the Indonesia Stock Exchange (IDX) does not insist on IC disclosure. However, for small companies, the existence of gender diversity has a significant effect on IC disclosure. The findings of this study suggest that policymakers and standard makers must consider the inclusion of IC disclosure on the annual report as mandatory.

Because of new requirements related to the employment of SMT(Surface Mounting Technology) manufacturing and the diversity of components on high density PCB(printed circuit boards), Thermal control of the reflow process is required in oder to achieve acceptable yields and reliability of SMT assemblies. Accurate control of the temperature distribution during the reflow process is one of the major requirements, especially in lead-free assembly. This study has been performed for reflow process using the commercial CFD tool(Fluent) for predicting flow and temperature distributions. There was flow recirculation region that had a weak point in the temperature uniformity. Porous plate was installed to prevent and minimize flow recirculation region for acquiring uniform temperature in oven. This paper provided design concept from CFD results of the steady state temperature distribution and flow field inside a reflow oven.

본 논문에서는 특정 공간의 흡연 여부를 감지하는 시스템을 소개한다. 제안하는 시스템은 라즈베리 파이로 이루어진 무선 애드혹 네트워크 기반 위에 구현되었다. 이는 상용 흡연 모니터링 시스템에 비하여 저가의 장치를 이용하여 경제적이며, 하나의 라즈베리파이를 이용한 또 다른 기존의 시스템에 비하여 확장성이 뛰어나다. 본 논문에서는 센서로부터 장시간 측정한 데이터를 이용하여 흡연 시와 비흡연 시 일산화탄소 농도의 확률밀도함수를 가우시안 함수로 근사화하였다. 이를 바탕으로 최대 우도 검파 (maximum likelihood detection) 기법을 이용하여, 일산탄소농도 값으로 흡연 상태를 추정하는 기법을 제안한다. 또한 애드혹 네트워크로 연결된 복수의 센서들로부터 수집한 값으로 흡연 상태를 추정하여 신뢰도를 높이고자 하였다.
