Critical gap analysis of merging sections at Kuala Lumpur middle ring road

At merging sections, drivers normally slow down and sometimes need to stop while seeking a suitable gap before merging with the mainstream. Thus, there will always be several observed rejected gaps and an accepted gap which can be used to determine the smallest average gap, so-called critical gap. This study was carried out to determine critical gap values at selected merging sections at the Jalan Tun Razak and the DUKE Expressway uses the Maximum Likelihood method. Data were collected by using videotaping method and the gap acceptance data were extracted for analysis. A gap acceptance event at highway merging sections in this study was redefined due to unavailability of stopping vehicles at the ramp junction. Therefore, the gap data were estimated starting from a ramp’s vehicle passing the end of gore marking to where it merges with the mainstream. The analysis of the critical gap takes into consideration accepted gaps greater than 5 seconds to avoid forced entry due to lead impedance of successive vehicles on mainstream. The critical gap values obtained in this study, according to vehicle classification were ranged between 4.5 to 5.0 seconds, which are slightly smaller if compared to critical gap values for particularly left turn from minor movement at priority junction of the Arahan Teknik (Jalan) 11/87 and the United States Highway Capacity Manual 2000. The findings shall help to study driving behavior of local drivers, especially at priority control facilities such as merging sections

Perkembangan Behavioral Accounting Wujud Open Ended Ilmu Akuntansi Sebagai Sosok Social Science

The shift of accountancy dicipline has been clearly marked over the past two decades. Normative accountancy that has triumphed for a few decades and has been an icon in accounting practices has gained criticism from many parties, both practitioners and academics. It wa due tothe fact that normative accountancy which is based on researches cannotbe implemented in every day lives. Concequently, a new insight is offering a new understanding of descriptive accountancy in real life.The shift of behaviour accounting is closely related to its epistemology underpinnings, where accounting is not a mono method in nature, but it is actually multi method. That is, whitin its epistemology design, which is the way dicipline is designed,accounting is recognizingand embracing many paradigms.Therefore, accounting is an open ended dicipline that is openended in nature toward social science theories, such as sociology, anthropology and psychology,especially when it is the non positivistic epistemology that is being used as its cornerstone in accounting development researches. This is where normative accounting emerged and developed to explain the phenomenon naturally.The area of behaviral accounting development into: (1) The antecedents and consequences of using acoounting information to evaluate subordinate performance; (2) The role of budget participation in organization control; (3) The consequences of incentive compensation contrancting; (4) The antecedents and consequences of effective control and budgetting system design

Mythology In Sulalatus Salatin: A Moral Responsibility In Fulfulling The King\u27s Vision

The Sulalatus Salatin is clearly a form of historical literature that contained a lot of stories, myth, especially during the period pre-Melaka until the existence of Melaka itself.The objective of this study is to identify the mythological aspect and its kinship with the king\u27s authority. The research will use cultural theories. Mythology has always been connected with the tales of gods which always have a kinship with the constituents of faith.This element usually associated with the beginning of a race or ancestral root of an individual, especially royalties which were invariably tied to the extraordinary & peculiar tales.In the essence, mythology is the tale of the origins which encompasses the roots of blood line, the name of a place, the arrival of Islam, etc. In the context of societal belief, mythology is not just something respectable, but the mythical event was thought to actually took place and studied as something sacred.This clearly proves that myth has already existed even before the emergence of Tun Seri Lanang as the author of Sulalatus Salatin. Therefore, this research is produced with the aim to observe the mythological elements in the text of Sulalatus Salatin and the role of its story as a moral duty in fulfilling the King\u27s wishes

Phytochemicals and antioxidant properties of different parts of Camellia sinensis leaves from Sabah Tea Plantation in Sabah, Malaysia

This study was conducted to determine the total phenolic (TPC) and total flavonoid content (TFC) as well as the antioxidant activity of 50% ethanolic extracts from different parts of Camellia sinensis (shoot, young and matured leaves). Comparison was also made between black (fermented) and green (unfermented) tea. For green tea, the results showed that the shoot contained significantly higher total phenolic content, followed by the young and matured leaves (p<0.05). The same trend was also observed for antioxidant activity as assessed using FRAP (ferric reducing/antioxidant power), DPPH (2,2-diphenyl 1-picrylhydrazyl) free radical scavenging assay and ABTS (2,2’-azinobis(3-ethylbenzthiazoline)-6-sulphonic) radical scavenging assays. As for black tea, the highest total phenolic and total flavonoid content were observed in the shoot, followed by the young and old leaves. The same trend of antioxidant activity with green tea was also observed in black tea extracts. In addition, black tea compost showed comparable high total phenolic and flavonoid content as well as antioxidant activities as assessed using different antioxidant assays. High antioxidant activity of tea leaves grown in Sabah might be contributed by phenolic phytochemicals that presence in the extract

Analyzing the effect of nozzle diameter in fused deposition modeling for extruding polylactic acid using open source 3D printing

Fused deposition modeling (FDM) is one of the Rapid Prototyping (RP) technologies. The 3D Printer has been widely used in the fabrication of 3D products. One of the main issues has been to obtain a high quality for the finished parts. The present study focuses on the effect of nozzle diameter in terms of pressure drop, geometrical error as well as extrusion time. While using polylactic acid (PLA) as a material, the research was conducted using Finite Element Analysis (FEA) by manipulating the nozzle diameter, and the pressure drop along the liquefier was observed. The geometrical error and printing time were also calculated by using different nozzle diameters. Analysis shows that the diameter of the nozzle significantly affects the pressure drop along the liquefier which influences the consistency of the road width thus affecting the quality of the product’s finish. The vital aspect is minimizing the pressure drop to be as low as possible, which will lead to a good quality final product. The results from the analysis demonstrate that a 0.2 mm nozzle diameter contributes the highest pressure drop, which is not within the optimum range. In this study, by considering several factors including pressure drop, geometrical error and printing time, a 0.3 mm nozzle diameter has been suggested as being in the optimum range for extruding PLA material using open-source 3D printing. The implication of this result is valuable for a better understanding of the melt flow behavior of the PLA material and for choosing the optimum nozzle diameter for 3D printing

Pyramidal structure, firm capital structure exploitation and ultimate owners' dominance

In this paper we investigate how pyramid structure, separating cash flow rights and control rights, allows ultimate owners to control the company's resources for the creation of private benefits and to avoid punishment for such conduct. Empirical tests are conducted using three-stage least squares regression. The estimated results provide support for the hypotheses proposed that the separation of cash flow rights and control rights have led to the use of excess leverage among pyramidal companies to preserve ultimate owners' control. High levels of leverage, affect the firm's valuation negatively because of the potential for financial distress. Thus, our findings may provide one additional explanation for the severity of the decrease in corporate value among the pyramidal companies in Malaysia as pointed out in the studies of Claessens et al. (2002), Lins (2003), and Lemmon and Lins (2003). Secondly, the empirical evidence from this study provides insight into the forces that influence corporate valuation of firms in developed countries particularly those that have pyramidal structure
