Abstract:
The study examines conceptually the detection of financial statements fraud using fraud pentagon. The study discusses the relationship between fraud pentagon and financial statement fraud. The methodology adopted in this study is library research whereby relevant and extant literature related to the elements in fraud pentagon were reviewed in relation to financial statements fraud. In the search for literature, it was observed that the various elements of fraud pentagon such as pressure (financial targets, financial stability, institutional ownership and external pressure), opportunity (ineffective monitoring and nature of industry), rationalization (auditor switching and change of director), competence (the changes in the company directorship and the proportion of independent directors in the board) and arrogance (frequent number of CEO's picture and CEO duality) significantly affect financial statements fraud. This study recommends that fraud pentagon should be given the statutory support in order to address financial statements fraud.

Abstract:
This study aims to examine how the influence of fraudulent financial reporting on firm value is viewed from the perspective of a pentagon fraud with a sample of 71 companies from the infrastructure, utilities and transportation sectors in the Indonesia Stock Exchange in 2014-2018. The sample selection used was purposive sampling method. Company value is measured by price book value, financial statement fraud is measured by fraud-score models. There are two variables that have a positive and significant influence, namely the opportunity and arrogance variables, the two variables present two of the five elements of pentagon fraud, where as the three variables, pressure, rasionalization, competence, do not affect the fraudulent financial reporting. The results of this study have proven that fraudulent financial reporting has a negative effect on firm value.

Abstract:
In this paper, we present a comprehensive study on the propagation and dispersion characteristics of A1 mode propagating in Z-cut LiNbO3 membrane. The A1 mode resonators with pentagon spiral electrodes utilizing Z-cut lithium niobate (LiNbO3) thin film are designed and fabricated. The proposed structure excites the A1 mode waves in both x- and y-direction by utilizing both the piezoelectric constants e24 and e15 due to applying voltage along both the x- and y-direction by arranging pentagon spiral electrode. The fabricated resonator operates at 5.43 GHz with no spurious mode and effective electromechanical coupling coefficient (Keff2) of 21.3%, when the width of electrode is 1 µm and the pitch is 5 µm. Moreover, we present a comprehensive study of the effect of different structure parameters on resonance frequency and Keff2 of XBAR. The Keff2 keeps a constant with varied thickness of LiNbO3 thin film and different electrode rotation angles, while it declines with the increase of p from 5 to 20 µm. The proposed XBAR with pentagon spiral electrodes realize high frequency response with no spurious mode and tunable Keff2, which shows promising prospects to satisfy the needs of various 5 G high-band application.

Abstract:
The aim of this study is to examine the element of fraud in fraud pentagon theory against indications of fraudulent financial reporting. The Fraud pentagon model is a further development of classical fraud triangle theory and fraud diamond theory. It includes pressure on financial targets, financial stability, external pressure, institutional ownership, nature of industry, ineffective monitoring, quality of external auditor, change in auditor, change of directors, and duality CEO. The indication of fraudulent financial reporting as dependent variable. Samples were selected using a purposive sampling method from 175 mining companies listed on Indonesia Stock Exchange during the year period 2014 – 2018, resulting in 70 firm-observations. Data analysis was conducted using the logistic regression method. The results of this study show that the change of directors is significant in detecting the occurrence of fraudulent financial reporting.

A novel unsymmetrical photochromic diarylethene compound bearing dithiol-pentane unit, 1-[2-methyl-5-(1,3-dithiol-pentane)-3-thienyl]-2-[2-methyl-3-benzofuran-yl]perfluoroyclopentene(1a) has been synthesized, and its photochromic, fluorescence and optical recording strorage properties were investigated. The compound exhibited remarkable photochromism and clear fluorescent switches both in solution and in PMMA film. Using diarylethene 1b/PMMA film as recording medium and a linearly polarized 650 nm laser diode for recording and readout, polarization multiplexed image recording can be carried out in this film. The results demonstrated that the diarylethene can be potentially used as polarization multiplexing holographic recording medium.

Abstract:
Most US military technology is produced by military industrial firms (MIFs). The federal government substantially funds these firms, and provides the principal MIFs with a steady flow of profitable contracts. Unlike civilian-oriented firms, MIFs virtually have guaranteed profits, and need not emphasize cost minimization as a survival strategy. Instead, MIF management strategy focuses on information gathering, lobbying efforts, and marshalling the MIF labor force in order to influence the contract awards process. The operation of MIFs depends upon a set of alliances within defense-dependent communities and among local leaders, MIF management, Congress, and the Pentagon. These relationships empower MIF management, ensure MIF longevity, and provide a community with employment and an economic base. Endogenous control, a commonly cited ingredient of local or regional development, may be achieved in defense-dependent communities, despite external funding. The power and control exercised by MIFs may not, however, represent a sufficient condition for ‘development’, given problems of inefficiency that tend to characterize these specialized firms.

Abstract:
An evaporating meniscus formed by a wetting °uid in a heated capillary slot with capillary driven °flow is numerically and experimentally investigated at the microscale and pore scale. In the microscale analysis, the contact line region of an extended evaporating thin ¯lm meniscus is numerically investigated to study the influence of °uid properties on the heat transfer. The governing equations to describe the fluid °flow, heat and mass transfer phenomena in an evaporating extended meniscus are grouped uniquely as function of °uid dependent parameters, namely the interline heat flow number and heat pipe ¯figure of merit. A physical interpretation of these parameters is presented. Numerical experiments conducted with different working °fluids show that a °uid with a high interline heat °flow parameter and heat pipe ¯figure of merit also has a high cumulative heat transfer in the micro region encompassing the evaporating thin ¯lm. In the pore scale analysis, the evaporation from a pentane meniscus in a heated capillary slot is experimentally and numerically investigated to study how the wetting characteristics are influenced with heat input. In the experimental investigation, a test set up is fabricated with a heated glass capillary slot that is partially immersed in a constant temperature bath with constant °uid level. A novel aspect of this experiment is that both the wicking height and steady state evaporation mass flow rate are measured simultaneously. Based on a macroscopic force balance, the apparent contact angle of the evaporating meniscus is experimentally estimated from the wicking height and mass flow rate. This is compared with the results obtained using evaporating thin ¯lm theory. The experimentally estimated contact angle is higher than that obtained from the thin ¯lm model but both experiment and theory show similar trends. In the numerical study, a ¯finite volume numerical model of an evaporating meniscus in a heated capillary slot (simulating the above experimental condition) is developed for predicting the wicking height and mass flow rate. This model includes: (i) one-dimensional heat transfer and °uid °flow in the liquid and vapour regions of the capillary slot, (ii) one{dimensional evaporating thin ¯lm model for the meniscus region, and (iii) two-dimensional conduction heat transfer in the capillary wall. Correlations obtained from the evaporating thin{¯lm theory in terms of cumulative heat transfer and apparent contact angle are applied to the pore level problem. The problem is solved iteratively between the micro and pore scales till convergence is achieved. The wicking height is influenced by the change in apparent contact angle and the pressure drops to flow of liquid and vapor in the capillary slot that is a function of evaporation mass °ow rate. Heat input to the capillary slot increases both the contact angle in the evaporating meniscus and the frictional pressure drops in the liquid and vapor regions. In the present study, the influence of increased contact angle is more significant and the liquid and vapor pressure drops are negligible. The trends in the wicking height, mass flow rate and conductance are similar to the experimental data. The proposed numerical approach using correlations from thin ¯lm theory to link the micro and macro scales yields results that are consistent with experimental data. The results show that the change in contact angle can degrade the ability of the liquid to wet the pore and hence result in a lower heat transfer coefficident.

Abstract:
This chapter explores the role of technological adaptability during the wars in Afghanistan and Iraq. At the tactical level, it examines how soldiers in Iraq developed “hillbilly armor” to try to protect their vulnerable vehicles from roadside bombs, and how Apache helicopters were successfully adapted to conduct close air support missions in Afghanistan. It also argues, however, that technological adaptability at the institutional level involved disastrous failures. In Iraq, virtually all senior Pentagon officials repeatedly resisted providing adequate numbers of life-saving vehicles called MRAPs to deployed soldiers facing grave threats from improvised explosive devices. And in Afghanistan, the army stubbornly supported its poorly performing intelligence analysis system, called DCGS-A, for more than a decade, despite overwhelming evidence that commercially available software from Palantir would work better and save the lives of more soldiers.

Abstract This chapter discusses the morality of the Vietnam War and the new expressions of dissent. In the wake of the Cambodian invasion and the failed operation in Laos, for the first time a Lou Harris poll revealed that a majority of Americans considered the conflict to be morally wrong. People were asking what justified the continued killing of soldiers and civilians in a palpably unsuccessful venture. The most dramatic development was the appearance of Vietnam Veterans Against the War (VVAW), who gathered in Washington for a week of protests that included a ceremony at Arlington National Cemetery, powerful congressional testimony by John Kerry, and an emotional demonstration by veterans who threw away their medals in front of the Capitol. Rocked by these protests, the Nixon administration hoped that disruptive activities of the Mayday Tribe following the appearance of the veterans would be politically helpful, and toward that end applauded mass arrests. The chapter also discusses the release of the Pentagon Papers by Daniel Ellsberg and the Supreme Court decision upholding the right of newspapers to publish.

Abstract:
Abstract Diplomacy with Beijing assumed particular importance, given the Vietnam woes and furor surrounding the Pentagon Papers. As of July 1971, both President Richard Nixon and National Security Advisor Henry Kissinger were hoping that success in this venture would boost Nixon’s political standing at home and perhaps facilitate a diplomatic breakthrough with Hanoi. Both men were determined that the card be played well—and secretly. The first high-level negotiation with the Chinese government since 1949, they limited news of it to a handful of people and excluded the State Department. Kissinger was authorized to promise Chinese prime minister Zhou Enlai that the United States would take “no major steps affecting your interests” without prior discussion with the Chinese government. Zhou Enlai was gracious in response but turned quickly to the question of Taiwan. According to Kissinger, the settlement of the Taiwan question was linked to the resolution of the Vietnam War. Following two and a half days of intense conversation, the meetings ended on a hopeful note. The chapter also discusses the changing attitude of Nixon and Kissinger toward representation of the People’s Republic of China in the United Nations and in the Security Council. The two are clearly moving away from their support of Chiang Kai-Shek.

Abstract:
When the U.S. invaded Iraq, they acted according to their standard doctrine of using overwhelming force to incapacitate and destroy the enemy. Despite their initial success, the U.S. forces quickly lost control and faced an insurgency, a kind of warfare for which they were ill prepared both in terms of doctrine and institutional culture. Lacking an up-to-date counter-insurgency doctrine, in the fall of 2003, the Pentagon turned to Gillo Pontecorvo’s 1966 anticolonial docudrama The Battle of Algiers for instruction. This chapter, by Vinzenz Hediger, traces the role the film played in the elaboration of the COIN doctrine and discusses why, despite the considerable intellectual efforts of the authors of manual FM 3-24, the film’s lessons went largely unheeded by the American military.

Abstract:
Ralph Waldo Emerson was Cavell’s most significant intellectual mentor. He claimed that Emerson made a singular contribution to the history of American thought with a clarion call to humanity to become who we are. Emerson sought to revolutionize moral thought by making self realization as central to that enterprise as the Kantian concern for duty or the Utilitarian calculus of what will best serve the greatest number. Cavell situates Emerson’s perfectionism at the heart of his genre theories, and of his account of what “The Good of Film” really amounts to. The chapterl illustrates Cavell’s notion of this Emersonian paragon by discussing Steven Spielberg’s recent treatment of the ascendency of Kay Graham (Meryl Streep), as she takes the reins at The Post and decides it should publish the Pentagon papers despite the legal ban on doing so.

The chapter’s analysis testifies to the enduring popularity of key ideational themes and mythologies, such as American exceptionalism, military heroism, and external threats endangering the existence of the United States, its interests and values under the Obama presidency. The serial reproduction of these national security narratives, realized in multi-million dollar film productions, illustrates the cross-discursive leverage of American hegemony over alternative formulations of grand strategy under the Obama presidency and the popularity of a particular national security imagery of American geopolitical identity.

"niques were prepared using pentane as the solvent. Similar methods were used in preparing calibration samples with the mold release, solder flux, and hydraulic oil samples. All contaminated coupons were gentl y heated in an oven at 50°C for several days to remove both semi-volatile and volatile components. This served to stabi-lize the contaminants, allowing for quantification by weighing. Once the weights became stable, the coupons were cooled and weighed to determine the amount of contaminant present on the surface. When not being weighed or examined, the coupons were kept in a desiccator. 3. RESULTS AND DISCUSSION Grazing-angle incidence reflectance spectroscopy acts to enhance the detection sensitivity for thin layers of residue predominantly through improved coupling of th e electric field intensity of the incident beam with the vibrating dipoles of the surface contaminant layer perpendicular to the metallic surface. Some additional enhancement of the infrared absorption spectrum will also occur due to a length-ening of the effective path length through the absorbing thin film layer [4-6]. If the optical properties of both thin film and substrate are known (or can be de-termined), the reflection-absorption spectrum can be calculated as a function of film thickness and angle of incidence. This capability is particularly useful for in-terpreting experimental data and designing optical instrumentation. Computer codes written at Sandia [7] performed these calculations for a variety of materials. 3.1. FTIR measurements FTIR reflectance data for the full drawing-agent sample set were obtained at NFESC and Sandia using angles of incidence of 75 and 60° for average film thickness ranging from 0.1 to 1 |im, and aluminum substrates with surface finish ranging from 600 to 80 grit. Since the surface finishing operation produced a highly directional roughness, measurements were made both longitudinally and transversely with respect to the polishing grooves.

Abstract:
Image analyzing interferometry was used to study the spreading characteristics of an evaporating meniscus containing octane (purity: 99+ %) on a quartz surface. The thickness and curvature profiles in the contact line region of the meniscus were obtained using a microscopic data analysis procedure. The results obtained for the octane were compared with that of pure pentane under similar operating conditions. Isothermal experimental conditions of the meniscus were used for the in-situ estimation of the retarded dispersion constant. The experimental results for the pure pentane demonstrate that the disjoining pressure (the intermolecular interactions) in the thin film region controls the fluid flow. Also, an imbalance between the disjoining pressure in the thin film region and the capillary pressure in the thicker meniscus region resulted in a creeping evaporating pentane meniscus, which spread over the solid (quartz) surface. On the contrary, for less pure octane, the intermolecular interactions between octane and quartz had a significantly different contribution for fluid flow and hence the octane meniscus of lower purity did not creep over the quartz surface. As a result, we had a stationary, evaporating octane meniscus. Using the experimental data and a simple model for velocity distribution, we evaluated the Marangoni shear in a portion of the stationary, evaporating octane meniscus. An extremely small change in the concentration due to distillation had a significant effect on fluid flow and microscale heat transfer. Also, it was found that non-idealities in small interfacial systems, i.e. the presence of impurities in the working fluid, can have a significant effect on the thickness of the adsorbed film and therefore the spreading characteristics of an almost pure octane meniscus.

Full text
Abstract:
A novel type of polarizer is introduced. These polarizers have high extinction-ratio, high transmission, and high laser damage threshold, hence they could be used in high power laser systems. The polarizers are shaped like a regular penta prism, thus they are a device of a constant angular deviation. The polarization effects occur upon the two internal reflections in the prism. Two types of polarizer are introduced: isotropic and unisotropic. The isotropic polarizer is made of high index refraction glass, coated with dielectric multilayer thin film systems. Due to the two internal cascade reflections, both the p- and s-rays have a high extinction ratio. The unisotropic polarizer is made of a birefringent crystal where angular polarization splitting is obtained from the bireflectance (double reflection) effect. In a prism made of a biaxial crystal, fanning of a laser beam into two to eight polarized beams is possible. These polarizers can be used in the UV, visible, and IR spectral regions. Theoretical considerations and examples are introduced and discussed.

Abstract:
The thickness and curvature profiles in the contact line region of a moving evaporating thin liquid film of pentane on a quartz substrate were measured for the thickness region, δ < 2.5 microns. The critical region, δ < 0.1 microns, was emphasized. The profiles were obtained using image analyzing interferometry and an improved data analysis procedure. The precursor adsorbed film, the thickness, the curvature, and interfacial slope (variation of the local “apparent contact angle”) profiles were consistent with previous models based on interfacial concepts. Isothermal equilibrium conditions were used to evaluate the Hamaker constant in-situ and to verify the accuracy of the procedures. The profiles give fundamental insights into the phenomena of phase change, pressure gradient, fluid flow, spreading, and the physics of interfacial phenomena in the contact line region. The experimental results demonstrate explicitly for the first time, with microscopic detail, that the disjoining pressure controls fluid flow within an evaporating completely wetting thin curved film and the stability of the thin film. The change in the thickness of the adsorbed film with time is demonstrated for the first time.

Abstract:
This work aims to investigate the effect of liquid entrainment on liquid film dryout in annular flow for flow boiling. Entrainment and deposition rates of droplets were included in mass conservation equations to estimate the local liquid film mass flux in annular flow, and the critical vapor quality at dryout conditions. Different entrainment rate correlations were evaluated using flow boiling data of n-pentane, iso-octane and water. Effect of the initial entrained fraction (IEF) at the churn-annular transition was also investigated. A transition Boiling number was proposed to separate the IEF-sensitive region at high Boiling numbers and the IEF-insensitive region low Boiling numbers. Besides, the diameter effect on dryout vapor quality was studied. The dryout vapor quality increases with decreasing tube diameter. A possible reason is that there is less droplet entrainment in smaller tubes, as evidenced in numerous flow pattern visualization studies. It needs to be pointed out that the dryout characteristics of submillimeter channels to be different because of different mechanisms of dryout, i.e., drying of liquid film underneath long vapor slugs and flow boiling instabilities.

Abstract:
The paper describes results of a parametric study obtained while using an analytical model described earlier (Bunama and Karim, 1997b) investigating the combined effects of mass, energy and momentum transfer with variable transport and thermodynamic properties on the formation of fuel vapour-air mixtures above a stagnant liquid fuel surface within the confines of a vertical cylindrical vessel. This was done mainly to examine the establishment of the formation of flammable mixtures and their changes in size and location with time within liquid fuel tanks that are partially empty. The effects of changes in the ambient and wall temperatures, presence of liquid on the walls and vessel geometry were considered. Moreover, the results of a corresponding experimental investigation are presented. Much of the data relates to the high volatility fuel n-pentane that represents the tighter fuel fractions in commercial fuels which through their early evaporation contribute much to the fire hazards in fuel tanks.

Abstract:
Abstract Several studies have demonstrated the nature of wax and asphaltene interactions and their impact on crude properties, including deposition characteristics. Laboratory and field studies have confirmed organic deposits from offshore oil wells containing asphaltenes and paraffins coprecipitated together to form solid aggregates. These can be described as "Waxphaltenes." This study used different techniques to understand better the properties of waxphaltenes from an offshore operation and how they interact with different rock mineralogy. It was found that mixing crude oil with acetone or methyl ethyl ketone (MEK) is highly efficient in the precipitation and isolation of heavy organics and other polar fractions than the traditional use of pentane or heptane from bulk hydrocarbon fluid. GC, FTIR, NMR, and elemental analysis revealed the composition characteristics of isolated organic solids. ATR-FTIR and AFM-IR methods were used to monitor the deposition of oil and organics on the surface of carbonate and silicate rocks. Water imbibition and solvent wash could remove some of the waxphaltenes dominated deposit from the surface but leave a key monolayer of organics adhered to the surface via hydrogen- or ionic bonding, which act as hydrophobic film. A plausible mechanism of such film formation may include di-or multivalent ions as bridging agents to bind with carboxylate and hydroxyl groups present in organic fractions.

Abstract:
The impulse response method is widely used for heat transfer analysis in turbomachinery applications. Traditionally, the 1D method assumes a linear time invariant, isotropic, semi-infinite block and does not accurately model the behaviour of laminated materials. This paper evaluates the error introduced by the single layer assumption and outlines the required modifications for multilayer analysis. The analytic solution for an N layer, semi-infinite laminate is presented. Adapted multilayer basis functions are derived for the impulse response method and used to evaluate the impact of uniform, isotropic assumptions. A numerical solution to the laminate problem is also presented. A penta-diagonal inversion algorithm, for a modified Crank-Nicolson scheme, is evaluated for fast stable implementation of multilayer simulation. The scheme shows comparable performance to the impulse response, whilst removing the requirement for linear time invariance. The methods are demonstrated in the case of analysing a thin film gauge, used in laboratory analysis of heat transfer in a turbine nozzle guide vane. Thin film gauge manufacturing techniques have advanced significantly in recent years. Advanced multilayer constructions are now used however, post-processing commonly relies on outdated single layer methods. This paper provides a universal methodology, required to analyse modern-day multilayer heat transfer measurements.

Abstract:
The impulse response method is widely used for heat transfer analysis in turbomachinery applications. Traditionally, the 1D method assumes a: linear time invariant, isotropic, semi-infinite block with planar surfaces and does not accurately model the true geometric behaviour. This paper evaluates the error introduced by the planar assumption and outlines the required modifications for accurate freeform surface analysis. Adapted cylindrical basis functions are defined for the impulse response method and used to evaluate the impact of the 1D planar assumption. The analytic solutions for both convex and concave surfaces are presented. A penta-diagonal algorithm, for a modified numerical Crank-Nicolson scheme, is also evaluated for fast stable implementation of curved geometry simulation. The scheme shows comparable performance to the impulse response, whilst removing the requirement for linear time invariance. The new methods are demonstrated in the case of aerothermal analysis for heat transfer in a turbine nozzle guide vane. A 3D ANSYS simulation is used as a benchmark and further highlights the importance of the curvature effects. The methods are extended using curvature mapping for infrared camera data, enabling direct 3D thermal simulation or the fast calculation of freeform curvature. This paper defines the methodology to analyse heat transfer measurements on non-planar geometry.
