A survey research was undertaken in five organizations from the banking and manufacturing sectors in Nigeria using the simple random sampling technique and primary data was obtained with the aid structured questionnaire drawn on five likert’s scale. Four Hypotheses were formulated and tested using the T-test Statistics, Correlation and Regression Analysis at 95% confidence interval. It was discovered that internal control has a significant positive relationship with fraud prevention and that a weak internal control system permits fraudulent activities among staff. Based on the findings, it was recommended that organizations should continually and methodically review and evaluate the components of its internal control system whether activities are working as planned or not and that every organization should have pre-determined guidelines for conducting its operations and ensures compliance with these set guidelines while proactive steps should be taken to establish the independence of the internal audit by making the audit reportable to the governing council of an organization and not the chief executive officer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20control" title="internal control">internal control</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20system" title=" internal system"> internal system</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20audit" title=" internal audit"> internal audit</a>, <a href="https://publications.waset.org/abstracts/search?q=fraud%20prevention" title=" fraud prevention"> fraud prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=fraud%20detection" title=" fraud detection"> fraud detection</a> </p> <a href="https://publications.waset.org/abstracts/40751/impact-of-internal-control-on-fraud-detection-and-prevention-a-survey-of-selected-organisations-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40751.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26877</span> Internal Audit and the Effectiveness and Efficiency of Operations in Hospitals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naziru%20Suleiman">Naziru Suleiman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ever increasing cases of financial frauds and corporate accounting scandals in recent years have raised more concern on the operation of internal control mechanisms and performance of the internal audit departments in organizations. In most cases the seeming presence of both the internal control system and internal audit in organizations do not prove useful as frauds errors and irregularities are being perpetuated. The aim of this study, therefore, is to assess the role of internal audit in achieving the objectives of internal control system of federal hospitals in Kano State from the perception of the respondents. The study used survey research design and generated data from primary source by means of questionnaire. A total number of 100 copies of questionnaire were administered out of which 68 were duly completed and returned. Cronbach’s alpha was used to test the internal validity of the various items in the constructs. Descriptive statistics, chi-square test, Mann Whitney U test and Kruskal Wallis ANOVA were employed for the analysis of data. The study finds that from the perception of the respondents, internal audit departments in Federal Hospitals in Kano State are effective and that they contribute positively to the overall attainment of the objectives of internal control system of these hospitals. There is no significant difference found on the views of the respondents from the three hospitals. Hence, the study concludes that strong and functional internal audit department is a basic requirement for effectiveness of operations of the internal control system. In the light of the findings, it is recommended that internal audit should continue to ensure that the objectives of internal control system of these hospitals are achieved through proper and adequate evaluation and review of the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20audit" title="internal audit">internal audit</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20control" title=" internal control"> internal control</a>, <a href="https://publications.waset.org/abstracts/search?q=federal%20hospitals" title=" federal hospitals"> federal hospitals</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20frauds" title=" financial frauds"> financial frauds</a> </p> <a href="https://publications.waset.org/abstracts/7110/internal-audit-and-the-effectiveness-and-efficiency-of-operations-in-hospitals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7110.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26876</span> Effect of Internal Control Weaknesses and Audit Opinion to the Findings of State Losses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wiji%20Wijaya">Wiji Wijaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this research is to examine the effect of internal control weaknesses and audit opinion on the state’s loss findings of audit compliance to the regulation in public sector. The samples of this research consisted of 175 local government financial statements in the area of Central Java Province at 2009 until 2013. Area sampling design was used to select the financial statements. This study using quantitative descriptive statistical analysis and regression was run for data analysis and hypothesis examination. Result of this study indicated that internal control weaknesses and audit opinion contributes a positive influence which is significant to the state’s loss findings of audit compliance to the regulation. The internal control weaknesses that affect the state's loss finding are weakness control system of accounting and reporting with the value of the critical ratio 0.010 p 2.613 ; weakness budget execution control system with critical ratio value of 3.421 p 0.001 and weaknesses internal control structure with critical ratio value of 2.246 p 0.026 .

While internal control system exists in all institutions, the outlined objectives above are far from being achieved. The paper; therefore, assesses the effectiveness of internal control system in tertiary educational institutions in Nasarawa State, Nigeria with the specific focus on the Nasarawa state Polytechnic, Lafia. The study is survey; hence, a simple closed-ended questionnaire was developed and administered to a sample of twenty-seven (27) member staff from the Bursary and the internal audit unit of the Nasarawa State Polytechnic, Lafia to obtain data for analysis purposes and to test the study hypothesis. Responses from the questionnaire were analyzed using a simple percentage and chi-square. Findings shows that the right people are not assigned to the right job in the department, budget, and management accounting were never used in the institution’s operations and checking of subordinate by their superior officers is not regular. This renders the current internal control structure of the Polytechnic as ineffective and weak. The paper therefore, recommends that: transparency should be seen as significant, as the institution work toward meeting its objectives, therefore, it means that the right staff is assigned to the right job and regular checking of the subordinates by their ensued superiors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20control" title="internal control">internal control</a>, <a href="https://publications.waset.org/abstracts/search?q=tertiary%20educational%20intuitions" title=" tertiary educational intuitions"> tertiary educational intuitions</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a> </p> <a href="https://publications.waset.org/abstracts/38071/effective-internal-control-system-in-the-nasarawa-state-tertiary-educational-institutions-for-efficiency-a-case-of-nasarawa-state-polytechnic-lafia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38071.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">213</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26874</span> Design of Lead-Lag Based Internal Model Controller for Binary Distillation Column</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rakesh%20Kumar%20Mishra">Rakesh Kumar Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarun%20Kumar%20Dan"> Tarun Kumar Dan </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lead-Lag based Internal Model Control method is proposed based on Internal Model Control (IMC) strategy.

They both have a significantly higher score on Rotter's Locus of Control Scale, and they are quite xenophobic (54%) according to Bogardus Social Distance Scale. Present research suggests their motives are different. Principle components analysis shows that extremists with internal control reject migrants because of welfare chauvinism and they think that there is some kind of political conspirationism behind the European Refugee Crisis. Contrarily extremist with external control believe in a common enemy and they are significantly more ethnocentric and less skeptical in politics. Results suggest that extremist with internal control shows hostility toward minorities and migrants mainly because of their own reference group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control" title="control">control</a>, <a href="https://publications.waset.org/abstracts/search?q=extremist" title=" extremist"> extremist</a>, <a href="https://publications.waset.org/abstracts/search?q=migrant" title=" migrant"> migrant</a>, <a href="https://publications.waset.org/abstracts/search?q=right-wing" title=" right-wing"> right-wing</a> </p> <a href="https://publications.waset.org/abstracts/41807/the-role-of-internal-and-external-control-in-the-migrant-related-representations-of-right-wing-extremists" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41807.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">278</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26871</span> Research on Measuring Operational Risk in Commercial Banks Based on Internal Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baobao%20Li">Baobao Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Operational risk covers all operations of commercial banks and has a close relationship with the bank’s internal control. But in the commercial banks' management practice, internal control is always separated from the operational risk measurement. With the increasing of operational risk events in recent years, operational risk is paid more and more attention by regulators and banks’ managements. The paper first discussed the relationship between internal control and operational risk management and used CVaR-POT model to measure operational risk, and then put forward a modified measurement method (to use operational risk assessment results to modify the measurement results of the CVaR-POT model). The paper also analyzed the necessity and rationality of this method. The method takes into consideration the influence of internal control, improves the accuracy and effectiveness of operational risk measurement and save the economic capital for commercial banks, avoiding the drawbacks of using some mainstream models one-sidedly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commercial%20banks" title="commercial banks">commercial banks</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20control" title=" internal control"> internal control</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20risk" title=" operational risk"> operational risk</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20measurement" title=" risk measurement"> risk measurement</a> </p> <a href="https://publications.waset.org/abstracts/10143/research-on-measuring-operational-risk-in-commercial-banks-based-on-internal-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10143.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26870</span> Research on Executive Compensation Incentives and Internal Control: Evidence from China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yinjie%20Han">Yinjie Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the impact of executive compensation incentives on internal control effectiveness and further analyzes the moderating role of digital transformation in this relationship. Through empirical analysis of relevant data of A-share listed companies in Shanghai and Shenzhen from 2012 to 2022, the results of the study show that there is a significant positive relationship between executive compensation incentives and internal control quality. Digital transformation plays an important moderating role in this relationship. Specifically, executive compensation incentives directly enhance the effectiveness of internal control by increasing executives' motivation and responsibility. At the same time, digital transformation further strengthens the positive impact of executive compensation incentives on the quality of internal controls by increasing information transparency and management efficiency. In addition, the study finds that the impact of executive compensation incentives on internal control quality is more significant in firms with higher levels of digital transformation. This study provides theoretical and practical guidance for enterprises to design and implement effective executive compensation incentives, promote digital transformation, and improve internal control quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=executive%20compensation%20incentives" title="executive compensation incentives">executive compensation incentives</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20control" title=" internal control"> internal control</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20transformation" title=" digital transformation"> digital transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title=" corporate governance"> corporate governance</a> </p> <a href="https://publications.waset.org/abstracts/191941/research-on-executive-compensation-incentives-and-internal-control-evidence-from-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191941.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">22</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26869</span> A Constrained Model Predictive Control Scheme for Simultaneous Control of Temperature and Hygrometry in Greenhouses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayoub%20Moufid">Ayoub Moufid</a>, <a href="https://publications.waset.org/abstracts/search?q=Najib%20Bennis"> Najib Bennis</a>, <a href="https://publications.waset.org/abstracts/search?q=Soumia%20El%20Hani"> Soumia El Hani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of greenhouse climate control is to improve the culture development and to minimize the production costs. A greenhouse is an open system to external environment and the challenge is to regulate the internal climate despite the strong meteorological disturbances. The internal state of greenhouse considered in this work is defined by too relevant and coupled variables, namely inside temperature and hygrometry. These two variables are chosen to describe the internal state of greenhouses due to their importance in the development of plants and their sensitivity to external climatic conditions, sources of weather disturbances. A multivariable model is proposed and validated by considering a greenhouse as black-box system and the least square method is applied to parameters identification basing on collected experimental measures. To regulate the internal climate, we propose a Model Predictive Control (MPC) scheme. This one considers the measured meteorological disturbances and the physical and operational constraints on the control and state variables. A successful feasibility study of the proposed controller is presented, and simulation results show good performances despite the high interaction between internal and external variables and the strong external meteorological disturbances. The inside temperature and hygrometry are tracking nearly the desired trajectories. A comparison study with an On/Off control applied to the same greenhouse confirms the efficiency of the MPC approach to inside climate control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20control" title="climate control">climate control</a>, <a href="https://publications.waset.org/abstracts/search?q=constraints" title=" constraints"> constraints</a>, <a href="https://publications.waset.org/abstracts/search?q=identification" title=" identification"> identification</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse" title=" greenhouse"> greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20predictive%20control" title=" model predictive control"> model predictive control</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/91637/a-constrained-model-predictive-control-scheme-for-simultaneous-control-of-temperature-and-hygrometry-in-greenhouses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91637.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">206</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26868</span> An Examination of Internal Control System, Executive Duality and Audit Alarm Committee of Listed Nigerian Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mansur%20Lubabah%20Kwanbo">Mansur Lubabah Kwanbo </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Existing literatures have demonstrated the importance of executive duality (ED) and audit committee (AC) in the financial growth of companies. To some extent this points to corporate governance mechanism aiming at addressing makers and implementers of company policies to be centered on promoting only company objectives. However, furthering organizational objectives needs an adequate structure of control to realize that. Recent development in the various industries in Nigeria have indicated the internal control system (ICS)has not been able to adequately address most of the activities that results in ills of sustaining growth for these industries. It is from this premise the study has as one of its objective to determine the extent to which ICS significantly relates to ED and AC in listed Nigerian corporation. Data were sourced from 308 financial statements and accounts of the corporations that made the sample of the study. Logistic regression aided the test of the hypothesis formulated for the study. Findings revealed a significant relationship between the study variables. The study concludes that the internal control system (ICS) is effective despite the bifurcation of executive duality (ED) and the presence of the Audit Committee (AC) to the extent of preventing ills that encourage lack of sustainability of company’s growth. Sustaining legitimate policies that translate into huge earnings, and create value to stake holders should be pursued. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audit%20committee%20%28AC%29" title="audit committee (AC)">audit committee (AC)</a>, <a href="https://publications.waset.org/abstracts/search?q=executive%20duality%20%28ED%29" title=" executive duality (ED)"> executive duality (ED)</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20control%20system%20%28ICS%29" title=" internal control system (ICS)"> internal control system (ICS)</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/28996/an-examination-of-internal-control-system-executive-duality-and-audit-alarm-committee-of-listed-nigerian-companies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28996.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26867</span> Mixed-ownership Reform and Quality of Internal Control of State-owned Enterprises: Logic and Evidence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mao%20Ju">Mao Ju</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a capital organizing form, the mixed-ownership reform of state-owned enterprises (SOEs) is an important way to stimulate enterprises’ vitality through reshaping the shareholding structure, enhancing mutual complementation of shareholders’ resources, and improving corporate governance and the quality of internal control. Based on the process of mixed-ownership reform and according to IPO and the change in the key shareholding structure of the listed companies, this paper divides the reform into two stages: primary mixed-ownership reform and secondary mixed-ownership reform (deeper mixed-ownership reform), and uses this as the basis to construct the proxy variable of the mixed-ownership reform of SOEs, research on the relationship between the mixed-ownership reform of SOEs and the quality of internal control. The research reveals that: (1) SOEs completing a secondary mixed-ownership reform can enhance the quality of internal control; (2) In the secondary mixed-ownership reform, the introduction of heterogeneous major shareholders will generate more obvious enhancement in the quality of internal control than the introduction of homogeneous major shareholders. Further research shows that the internal environment and marketization process play a moderating role in the process of the secondary mixed-ownership reform affecting the quality of internal control, that is, a better internal environment or a higher degree of marketization can promote the improvement of the quality of internal control in secondary mixed-ownership reform. The conclusion of the research provides experimental evidence for the expected results of the mixed-ownership reform policy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mixed-ownership%20reform%20of%20state-owned%20enterprises" title="mixed-ownership reform of state-owned enterprises">mixed-ownership reform of state-owned enterprises</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20mixed-ownership%20reform" title=" secondary mixed-ownership reform"> secondary mixed-ownership reform</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20internal%20control" title=" quality of internal control"> quality of internal control</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20mixed-ownership%20reform" title=" primary mixed-ownership reform"> primary mixed-ownership reform</a> </p> <a href="https://publications.waset.org/abstracts/192530/mixed-ownership-reform-and-quality-of-internal-control-of-state-owned-enterprises-logic-and-evidence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192530.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">20</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26866</span> Internal Leakage Analysis from Pd to Pc Port Direction in ECV Body Used in External Variable Type A/C Compressor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Iqbal%20Mahmud">M.

Islamic micro finance (IMF) named Baitul Maal Wat Tamwil (Bmt) plays a prominent role to eradicate this. Indonesia as the biggest muslim country has many successful applied products such as worldwide adopt group-based lending approach, flexible financing for farmers, and gold pawning. The Problems related to these models are operation risk management and internal control system (ICS). A proper ICS will help an organization in preventing the occurrence of bad financing through detecting error and irregularities in its operation. This study aims to seek a proper risk management scheme of credit system in Bmt and internal control system’s rank for every stage. Risk management variables are obtained at the first In-Depth Interview (IDI) and Focus Group Discussion (FGD) with Shariah supervisory boards, boards of directors, and operational managers. Survey was conducted covering nationwide data; West Java, South Sulawesi, and West Nusa Tenggara. Moreover, Content analysis is employed to build the relationship among these variables. Research Findings shows that risk management Characteristics in Indonesia involves ex ante, credit process, and ex post strategies to deal with risk in credit system. Ex-ante control consists of Shariah compliance, survey, group leader reference, and islamic forming orientation. Then, credit process involves saving, collateral, joint liability, loan repayment, and credit installment controlling. Finally, ex-post control includes shariah evaluation, credit evaluation, grace period and low installment provisions. In addition, internal control order sort three stages by its priority; Credit process as first rank, then ex-post control as second, and ex ante control as the last rank. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20control%20system" title="internal control system">internal control system</a>, <a href="https://publications.waset.org/abstracts/search?q=islamic%20micro%20finance" title=" islamic micro finance"> islamic micro finance</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty" title=" poverty"> poverty</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management "> risk management </a> </p> <a href="https://publications.waset.org/abstracts/19296/risk-management-in-islamic-micro-finance-credit-system-for-poverty-alleviation-from-qualitative-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19296.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">407</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26862</span> Fault Tolerant Control of the Dynamical Systems Based on Internal Structure Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Hashemi">Seyed Mohammad Hashemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahrokh%20Barati"> Shahrokh Barati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problem of fault-tolerant control (FTC) by accommodation method has been studied in this paper. The fault occurs in any system components such as actuators, sensors or internal structure of the system and leads to loss of performance and instability of the system. When a fault occurs, the purpose of the fault-tolerant control is designate strategy that can keep the control loop stable and system performance as much as possible perform it without shutting down the system. Here, the section of fault detection and isolation (FDI) system has been evaluated with regard to actuator's fault. Designing a fault detection and isolation system for a multi input-multi output (MIMO) is done by an unknown input observer, so the system is divided to several subsystems as the effect of other inputs such as disturbing given system state equations. In this observer design method, the effect of these disturbances will weaken and the only fault is detected on specific input. The results of this approach simulation can confirm the ability of the fault detection and isolation system design. After fault detection and isolation, it is necessary to redesign controller based on a suitable modification. In this regard after the use of unknown input observer theory and obtain residual signal and evaluate it, PID controller parameters redesigned for iterative. Stability of the closed loop system has proved in the presence of this method. Also, In order to soften the volatility caused by Annie variations of the PID controller parameters, modifying Sigma as a way acceptable solution used. Finally, the simulation results of three tank popular example confirm the accuracy of performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fault%20tolerant%20control" title="fault tolerant control">fault tolerant control</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20detection%20and%20isolation" title=" fault detection and isolation"> fault detection and isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=actuator%20fault" title=" actuator fault"> actuator fault</a>, <a href="https://publications.waset.org/abstracts/search?q=unknown%20input%20observer" title=" unknown input observer"> unknown input observer</a> </p> <a href="https://publications.waset.org/abstracts/36532/fault-tolerant-control-of-the-dynamical-systems-based-on-internal-structure-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36532.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">452</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26861</span> Development of a Plug-In Hybrid Powertrain System with Double Continuously Variable Transmissions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng-Chi%20Yu">Cheng-Chi Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi-Shiun%20Chiou"> Chi-Shiun Chiou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study developed a plug-in hybrid powertrain system which consisted of two continuous variable transmissions. By matching between the engine, motor, generator, and dual continuous variable transmissions, this integrated power system can take advantages of the components. The hybrid vehicle can be driven by the internal combustion engine, or electric motor alone, or by these two power sources together when the vehicle is driven in hard acceleration or high load. The energy management of this integrated hybrid system controls the power systems based on rule-based control strategy to achieve better fuel economy. When the vehicle driving power demand is low, the internal combustion engine is operating in the low efficiency region, so the internal combustion engine is shut down, and the vehicle is driven by motor only. When the vehicle driving power demand is high, internal combustion engine would operate in the high efficiency region; then the vehicle could be driven by internal combustion engine. This strategy would operate internal combustion engine only in optimal efficiency region to improve the fuel economy. In this research, the vehicle simulation model was built in MATLAB/ Simulink environment. The analysis results showed that the power coupled efficiency of the hybrid powertrain system with dual continuous variable transmissions was better than that of the Honda hybrid system on the market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plug-in%20hybrid%20power%20system" title="plug-in hybrid power system">plug-in hybrid power system</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20economy" title=" fuel economy"> fuel economy</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=continuously%20variable%20transmission" title=" continuously variable transmission"> continuously variable transmission</a> </p> <a href="https://publications.waset.org/abstracts/50655/development-of-a-plug-in-hybrid-powertrain-system-with-double-continuously-variable-transmissions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50655.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">289</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26860</span> Improving the Quantification Model of Internal Control Impact on Banking Risks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Ndaw">M.

The population of the study comprises the 89,275 members of staff in the 20 DMBs in Nigeria as at June 2019. Purposive and convenient sampling techniques were used in the selection of the 80 members of staff at the supervisory level of the Internal Audit Departments of the head offices of the sampled banks, that is, selecting 4 respondents (Audit Executive/Head, Internal Control; Manager, Operation Risk Management; Head, Financial Crime Control; the Chief Compliance Officer) from each of the 20 DMBs in Nigeria. A standard questionnaire was adapted from 2017/2018 Internal Control Questionnaire and Assessment, Bureau of Financial Monitoring and Accountability Florida Department of Economic Opportunity. It was modified to serve the purpose for which it was meant to serve. It was self-administered to gather data from the 80 respondents at the respective headquarters of the sampled banks at their respective locations across Nigeria. Two likert-scales was used in achieving the stated objectives. A logit regression was used in analysing the stated hypotheses. It was found that effect of monitoring activities using the construct of conduct of ongoing or separate evaluation (COSE), evaluation and communication of deficiencies (ECD) revealed that monitoring activities is significant and positively related to fraud’s detection and prevention in Nigerian DMBS. So also, it was found that control activities using selection and development of control activities (SDCA), selection and development of general controls over technology to prevent financial fraud (SDGCTF), development of control activities that gives room for transparency through procedures that put policies into actions (DCATPPA) contributed to influence fraud detection and prevention in the Nigerian DMBs. In addition, it was found that transparency, accountability, reliability, independence and value relevance have significant effect on fraud detection and prevention ibn Nigerian DMBs. The study concluded that the board of directors demonstrated independence from management and exercises oversight of the development and performance of internal control.

The population of the study comprises the 89,275 members of staff in the 20 DMBs in Nigeria as at June 2019. Purposive and convenient sampling techniques were used in the selection of the 80 members of staff at the supervisory level of the Internal Audit Departments of the head offices of the sampled banks, that is, selecting 4 respondents (Audit Executive/Head, Internal Control; Manager, Operation Risk Management; Head, Financial Crime Control; the Chief Compliance Officer) from each of the 20 DMBs in Nigeria. A standard questionnaire was adapted from 2017/2018 Internal Control Questionnaire and Assessment, Bureau of Financial Monitoring and Accountability Florida Department of Economic Opportunity. It was modified to serve the purpose for which it was meant to serve. It was self-administered to gather data from the 80 respondents at the respective headquarters of the sampled banks at their respective locations across Nigeria. Two likert-scales was used in achieving the stated objectives. A logit regression was used in analysing the stated hypotheses. It was found that effect of monitoring activities using the construct of conduct of ongoing or separate evaluation (COSE), evaluation and communication of deficiencies (ECD) revealed that monitoring activities is significant and positively related to fraud’s detection and prevention in Nigerian DMBS. So also, it was found that control activities using selection and development of control activities (SDCA), selection and development of general controls over technology to prevent financial fraud (SDGCTF), development of control activities that gives room for transparency through procedures that put policies into actions (DCATPPA) contributed to influence fraud detection and prevention in the Nigerian DMBs. In addition, it was found that transparency, accountability, reliability, independence and value relevance have significant effect on fraud detection and prevention ibn Nigerian DMBs. The study concluded that the board of directors demonstrated independence from management and exercises oversight of the development and performance of internal control. Part of the conclusion was that there was accountability on the part of the owners and preparers of the financial reports and that the system gives room for the members of staff to account for their responsibilities.

The simplified decoupling is firstly introduced for multivariable processes by using coefficient matching to obtain a stable, proper, and causal simplified decoupler. Accordingly, transfer functions of decoupled apparent processes can be expressed as a set of <em>n</em> equivalent independent processes and then derived as a ratio of the original open-loop transfer function to the diagonal element of the dynamic relative gain array. The IMC-PID controller in series with filter is then directly employed to enhance the overall performance of the decoupling control system while avoiding difficulties arising from properties inherent to simplified decoupling. Some simulation studies are considered to demonstrate the simplicity and effectiveness of the proposed method. Simulations were conducted by tuning various controllers of the multivariate processes with multiple time delays. The results indicate that the proposed method consistently performs well with fast and well-balanced closed-loop time responses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coefficient%20matching%20method" title="coefficient matching method">coefficient matching method</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20model%20control%20%28IMC%29%20scheme" title=" internal model control (IMC) scheme"> internal model control (IMC) scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=PID%20controller%20cascaded%20filter" title=" PID controller cascaded filter"> PID controller cascaded filter</a>, <a href="https://publications.waset.org/abstracts/search?q=simplified%20decoupler" title=" simplified decoupler"> simplified decoupler</a> </p> <a href="https://publications.waset.org/abstracts/48781/design-of-imc-pid-controller-cascaded-filter-for-simplified-decoupling-control-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48781.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">442</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26856</span> Autonomous Flight Control for Multirotor by Alternative Input Output State Linearization with Nested Saturations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yong%20Eun%20Yoon">Yong Eun Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20N.%20Johnson"> Eric N.

Together with its popularity, the needs for proper flight control is growing because in most applications it is required to conduct its missions autonomously, which is in many aspects based on autonomous flight control. There have been many studies about the flight control for multirotor, but there is still room for enhancements in terms of performance and efficiency. This paper presents an autonomous flight control method for multirotor based on alternative input output linearization coupled with nested saturations. With alternative choice of the output of the multirotor flight control system, we can reduce computational cost regarding Lie algebra, and the linearized system can be stabilized with the introduction of nested saturations with real poles of our own design. Stabilization of internal dynamics is also based on the nested saturations and accompanies the determination of part of desired states. In particular, outer control loops involving state variables which originally are not included in the output of the flight control system is naturally rendered through this internal dynamics stabilization. We can also observe that desired tilting angles are determined by error dynamics from outer loops. Simulation results show that in any tracking situations multirotor stabilizes itself with small time constants, preceded by tuning process for control parameters with relatively low degree of complexity. Future study includes control of piecewise linear behavior of multirotor with actuator saturations, and the optimal determination of desired states while tracking multiple waypoints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automatic%20flight%20control" title="automatic flight control">automatic flight control</a>, <a href="https://publications.waset.org/abstracts/search?q=input%20output%20linearization" title=" input output linearization"> input output linearization</a>, <a href="https://publications.waset.org/abstracts/search?q=multirotor" title=" multirotor"> multirotor</a>, <a href="https://publications.waset.org/abstracts/search?q=nested%20saturations" title=" nested saturations"> nested saturations</a> </p> <a href="https://publications.waset.org/abstracts/76979/autonomous-flight-control-for-multirotor-by-alternative-input-output-state-linearization-with-nested-saturations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76979.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">228</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26855</span> Bank Internal Controls and Credit Risk in Europe: A Quantitative Measurement Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ellis%20Kofi%20Akwaa-Sekyi">Ellis Kofi Akwaa-Sekyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordi%20Moreno%20Gen%C3%A9"> Jordi Moreno Gené</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Managerial actions which negatively profile banks and impair corporate reputation are addressed through effective internal control systems. Disregard for acceptable standards and procedures for granting credit have affected bank loan portfolios and could be cited for the crises in some European countries. The study intends to determine the effectiveness of internal control systems, investigate whether perceived agency problems exist on the part of board members and to establish the relationship between internal controls and credit risk among listed banks in the European Union. Drawing theoretical support from the behavioural compliance and agency theories, about seventeen internal control variables (drawn from the revised COSO framework), bank-specific, country, stock market and macro-economic variables will be involved in the study. A purely quantitative approach will be employed to model internal control variables covering the control environment, risk management, control activities, information and communication and monitoring. Panel data from 2005-2014 on listed banks from 28 European Union countries will be used for the study. Hypotheses will be tested and the Generalized Least Squares (GLS) regression will be run to establish the relationship between dependent and independent variables. The Hausman test will be used to select whether random or fixed effect model will be used. It is expected that listed banks will have sound internal control systems but their effectiveness cannot be confirmed. A perceived agency problem on the part of the board of directors is expected to be confirmed. The study expects significant effect of internal controls on credit risk. The study will uncover another perspective of internal controls as not only an operational risk issue but credit risk too. Banks will be cautious that observing effective internal control systems is an ethical and socially responsible act since the collapse (crisis) of financial institutions as a result of excessive default is a major contagion. This study deviates from the usual primary data approach to measuring internal control variables and rather models internal control variables in a quantitative approach for the panel data. Thus a grey area in approaching the revised COSO framework for internal controls is opened for further research. Most bank failures and crises could be averted if effective internal control systems are religiously adhered to. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agency%20theory" title="agency theory">agency theory</a>, <a href="https://publications.waset.org/abstracts/search?q=credit%20risk" title=" credit risk"> credit risk</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20controls" title=" internal controls"> internal controls</a>, <a href="https://publications.waset.org/abstracts/search?q=revised%20COSO%20framework" title=" revised COSO framework"> revised COSO framework</a> </p> <a href="https://publications.waset.org/abstracts/44022/bank-internal-controls-and-credit-risk-in-europe-a-quantitative-measurement-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44022.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">316</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26854</span> Climate Physical Processes Mathematical Modeling for Dome-Like Traditional Residential Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artem%20Sedov">Artem Sedov</a>, <a href="https://publications.waset.org/abstracts/search?q=Aigerim%20Uyzbayeva"> Aigerim Uyzbayeva</a>, <a href="https://publications.waset.org/abstracts/search?q=Valeriya%20Tyo"> Valeriya Tyo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presented article is showing results of dynamic modeling with Mathlab software of optimal automatic room climate control system for two experimental houses in Astana, one of which has circle plan and the other one has square plan.

In this work, due to complexity and non-linearity of the process, the H₂S gas separation and the intelligent fuzzy controller, which is used to enhance the process, are simulated in MATLAB – Simulink. The new design of fuzzy control for Gas Separator is discussed in this paper. The design is based on the utilization of linear state-estimation to generate the internal knowledge-base that stores input-output pairs. The obtained input/output pairs are then used to design a feedback fuzzy controller. The proposed closed-loop fuzzy control system maintains the system asymptotically-stability while it enhances the system time response to achieve better control of the concentration of the output gas from the tower.

On the basis of the fractional calculus, the analytical tuning rules of FOPI controller for the inner loop can be established in the frequency domain.

In comparison, the model of hydraulic clamping system was established by using AMESim. The related parameters as well as the energy consumption could be calculated. According to the analysis, the hydraulic system was optimized in order to reduce the energy consumption. <p class="card-text"><strong>Keywords:</strong> <a
