This paper presents direct simulation Monte Carlo (DSMC) numerical investigation of the dynamic behavior of a gas film in a microbeam. The microbeam undergoes large amplitude harmonic motion between its equilibrium position and the fixed substrate underneath. Unlike previous work in literature, the beam undergoes large displacements throughout the film gap thickness and the behavior of the gas film along with its impact on the moving microstructure (force exerted by gas on the beam's front and back faces) is discussed. Since the gas film thickness is of the order of few microns (i.e., 0.01 < Kn < 1), the rarefied gas exists in the noncontinuum regime and, as such, the DSMC method is used to simulate the fluid behavior. The impact of the squeeze film on the beam is investigated over a range of frequencies and velocity amplitudes, corresponding to ranges of dimensionless flow parameters such as the Reynolds, Strouhal, and Mach numbers on the gas film behavior. Moreover, the behavior of compressibility pressure waves as a function of these dimensionless groups is discussed for different simulation case studies.

The bullwhip effect is a pervasive phenomenon in all supply chains causing excessive inventory, delivery delays, deterioration of customer service, and high costs. Some researchers have studied this phenomenon from a financial perspective by shedding light on the phenomenon of cash flow bullwhip (CFB). The objective of this article is to provide the state of the art in relation to research work on CFB. Our ambition is not to make an exhaustive list, but to synthesize the main contributions, to enable us to identify other interesting research perspectives. In this regard, certain lines of research remain insufficiently explored, such as the role that supply chain digitization could play in controlling CFB, the impact of CFB on the profitability of companies, or the impacts of the omnichannel commerce on CFB.

The Impact

In this paper we analyzed the link between companies’ performance, in terms of cash and income, and the labor productivity or management rates, in case of the companies from the energy sector listed on the Bucharest Stock Exchange. We focused on the energy sector because of the impact that its expansion has on the evolution of economies around the world and because of its dynamics in the sense of gradually shifting to the use of energy from renewable sources. We have used panel regression models to analyze the operating cash flow and the profitability rates and the determination of a causal or dependency relationship with labor productivity or management rates. The results of this study show a significant negative correlation between operating cash flows and the average duration of stock rotation, and no correlation between productivity and the operating cash flow. Instead, the average duration of stock turnover does not at all influence the profitability rates, and productivity is always significant for the return on assets, ie forthe return on equitywith a positive coefficient, as expected. The gap between the average duration of payment of suppliers and the average duration of receivables does not significantly influence neither the cash flow nor the rates of return.

The Impact

The impacts of unsteady flow research activities on flow simulation methods used in the turbine design process are assessed. Results from experimental investigations that identify the impact of periodic unsteadiness on the time-averaged flows in turbines and results from numerical simulations obtained by using three-dimensional unsteady Computational Fluid Dynamics (CFD) codes indicate that some of the unsteady flow features can be fairly accurately predicted. Flow parameters that can be modeled with existing steady CFD codes are distinguished from those that require unsteady codes.

AbstractThe trench film cooling employs film holes embedded in a slot created on the surface that requires protection from the impact of hot mainstream flow. The present investigation employs Response Surface Methodology (RSM) approach coupled with CFD analysis to develop a regression predictive model and to optimize the trench geometric and flow parameters viz., trench width (w), trench depth (d), film hole compound angle (β) and blowing ratio (M). The Area-averaged film cooling effectiveness (ȠAA) were chosen as a response factor for RSM and with trench design and flow parameters used as input factors for regression analysis. Analysis of variance (ANOVA) analysis was carried out on the regression model to identify the influence of individual parameters. Three dimensional response surfaces that relate the effect of input parameters on the response factor were analyzed. Experimental results of a case identified from the RSM matrix was found to correlate well with computational investigations. Results from the study indicate that the parameters d, β and M have considerable impact on film cooling performance of test surface with trenches.

Purpose The present study aims to investigate the impact of the reduction of the corporate tax rate on corporate tax revenue. The study adopts the theory of taxation by Ibn Khaldun, depicted as the Laffer curve. Design/methodology/approach The paper analyses time series data for the period 1996 to 2014 using the autoregressive distributed lag (ARDL) approach. Findings The paper finds that the corporate tax rate has a dual effect on corporate tax revenue over the study period. It shows an inverted U-shape relationship between the corporate tax rate and corporate tax revenue and reveals that the optimal tax rate is 25.5156 per cent. Inferentially, a positive relationship exists between the two variables prior to the optimal tax rate, and a negative relationship prevails afterwards. A further test of causality shows a long-run unidirectional causality between corporate tax rate and corporate tax revenue. Research limitations/implications First, it should be noted that the policy was not implemented in isolation. Several other tax incentives were given to corporate tax payers, and therefore, such incentives should be controlled for to have a more insightful evaluation of the policy. Second and most important, there is a need to investigate whether the increased cash flow available to firms as a result of the reduction in the corporate tax rate adds value to firms. It is also necessary to investigate whether firms’ stakeholders benefited from the increased cash flow or was there managerial diversion of firms’ resources. Practical implications The policy of gradual reduction of the corporate tax rate in Malaysia is suspected to have a positive impact on the productivity of Malaysian companies, which has contributed to an increase in corporate tax revenue. It also has a positive impact on the economic growth of the country. It means that the lower corporate tax rate has actually reduced the cost of doing business in the country. Originality/value The benefit of increased corporate tax revenue needs to be investigated empirically for insightful policy evaluation. In Malaysia, however, such investigation is close to non-existent to the best knowledge of the researchers. Thus, the present study aims at investigating the impact of the policy of gradual reduction of the corporate tax rate on corporate tax revenue over an 18-year period from 1996 to 2014.

A conceptual model for analyzing the dynamics of the value of the project, achieved as a result of engineering, under conditions of uncertainty has been developed. In the methodological context, the proposed approach is based on an array of isovalues, each of which corresponds to its own level of optimism in forecasting the cash flow for the project. With the increase in the efficiency of the project due to engineering, the entire array of iso-value lines’ changes its geometrical position, moving further from the origin (in the four-dimensional space "time-benefit-cost-risk"). The proposed model includes three stages. At the first stage, input information is collected and the corresponding analysis is initiated. The result of the second stage is a multivariate cash flow forecast and calculation of the benefit-cost ratio (BCR) and its changes for each scenario. The third stage provides the calculation of the expected BCR and its change, an assessment of the risk of making an erroneous decision and changing this risk as a result of the engineering session. The model makes it possible to calculate the achieved proportion of the static and dynamic vectors of change in the value of the project, which is one of the key manifestations of the scientific novelty of the work. In the example considered, the share of the dynamic vector of growth in the value of the project was found to be 35.47 %. The model has an environmental property - the assessment of the success of value engineering under conditions of uncertainty is carried out on the basis of the annual total benefits and the annual total costs throughout the project cycle. Thus, the analysis takes into account the impact of the project on the environment, which is reflected in the risk assessment. The given case testifies to the feasibility of applying the model in the practice of engineering the value of construction projects.

ABSTRACTThis study aims to detect Cash Flow, Cash Holding and Financial Constraints effect on investment decisions of companies in Indonesia. Some of the previous studies outside Indonesia show evidence of the impact of cash flows and financial constraints on it’s investment level.Using Multiple Regression and Logistic Regression model, on five years data observation shows that cash flow and cash holding have a positive effect on investment level. Interaction test shows the effect of cash flow on investment in financially constrained different from financially unconstrained companies. In other words, the average rate of investment changes caused by the level of cash flow is the same for both companies. While the effect of cash holding on investment, no different in the company that financially constraint and financially unconstraint company.The contribution of this research is to provide insight to the parties related to the importance of cash flow and cash holding to the investment of a company. Based on the results it can be concluded that companies that have cash flow and high cash holding have greater investment opportunities, especially in companies that have problems in finding sources of funding.   ABSTRAKPenelitian ini bertujuan untuk mendeteksi pengaruh Arus Kas, Cash Holding dan Kendala Finansial terhadap keputusan investasi perusahaan di Indonesia. Beberapa penelitian sebelumnya di luar Indonesia menunjukkan bukti ada pengaruh Arus Kas dan Kendala Keuangan pada tingkat investasi.Dengan menggunakan model Regresi Berganda dan Regresi Logistik, pada pengamatan data selama lima tahun menunjukkan bahwa Arus Kas dan Cash Holding berpengaruh positif terhadap tingkat investasi. Uji interaksi menunjukkan pengaruh Arus Kas terhadap investasi pada perusahaan yang mengalami kendala pendanaan berbeda dengan perusahaan yang tidak mengalami kendala pendanaan. Dengan kata lain, tingkat rata-rata perubahan investasi yang disebabkan oleh tingkat arus kas adalah sama untuk kedua perusahaan. Sedangkan pengaruh Cash Holding terhadap investasi, tidak berbeda pada perusahaan yang mengalami kendala pendanaan maupun tidak.Kontribusi dari penelitian ini adalah untuk memberikan wawasan kepada pihak-pihak yang terkait dengan pentingnya arus kas dan Cash Holding untuk investasi perusahaan. Berdasarkan hasil tersebut dapat disimpulkan bahwa perusahaan yang memiliki Arus Kas dan Cash Holding yang tinggi memiliki peluang investasi yang lebih besar, terutama pada perusahaan yang memiliki masalah dalam mencari sumber pendanaan.
