Indonesian Journal of Electrical Engineering and Computer Science 19, no. 2 (August 1, 2020): 890. http://dx.doi.org/10.11591/ijeecs.v19.i2.pp890-899.
Full textAbstract:
<p>Supplier selection is essential to the business. The risks posed by suppliers will have a significant impact on the company's performance. Each business has distinct supplier features to mitigate this.These characteristics are divided into criteria in supplier selection. In this study, the criteria in supplier selection will be weighted by Best Worst Method (BWM) and comparing the three ranking methods, Complex Proportional Assessment (COPRAS), Multi-Objective Optimization berdasarkan Analisis Rasio (MOORA) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). The sample in this study is an ABC manufacturing company engaged in mining from Indonesia. From the results of the study, there were 16 criteria using the Delphi Method. These criteria are divided into four main criteria, namely service, quality, cost and time. From the results of weighting BWM, the price sub criteria on cost criteria have the greatest weight for ABC companies. The results of the weighting are then carried out by supplier ranking by comparing the COPRAS, MOORA and TOPSIS approaches. In comparing these three methods, approaches are used based on accuracy and complexity. The COPRAS method has the highest accuracy and lowest complexity according to the ABC company.</p>

In order to reach the performance of the permanent magnet embedded rotor, the choice of magnet is very important. It must be thermally stabilized, and at this point, discussion of eddy current losses is necessary.To proceed with this study, a permanent magnet embedded synchronous motor used in the compressor currently being designed was selected. To derive the eddy current losses in the neodymium-magnets, current density was calculated through the equation. The eddy current loss was mathematically derived using the magnetic conductivity and residual magnetic flux density. Finally, comparative verification was performed through finite element analysis simulation. In this paper, eddy current losses in a N series magnet are mathematically analyzed and we perform comparative verification through simulation using finite element analysis. The Br value indicating the residual magnetic flux density is the lowest in N30 series and the largestin the N48 series. In the case of using the N30 series, the amount of magnetic flux that can be generated is low, so in order to increase the same output, the electric field must be increased by drawing more current from the stator winding. That is, the torque can be further increased. However, since the magnetic flux density experienced by the permanent magnet also increases, eddy current loss that may occur in the magnet eventually increases. There are also a method of using a split magnet to reduce eddy current losses. Inthe case of a permanent magnet holding a large residual magnetic flux density, the magnets loss is reduced, but there is a disadvantage that the price may be expensive. The losses in the permanent magnet are dissipated as heat. If the eddy current loss increases, the magnet demagnetizes, which in turn leads to a decrease in performance. In the selection of magnets, analysis of losses is essential.

In the process of developing competitive advantages of industry in one area, it is requiredthat order of priority of industrial development policies be based on certain criteria/dimensionsin which this order is based on the orientation and development plan according to the perspectiveof the stakeholders in that area. The competitive advantages are related to the purposesof industry in achieving its best performance and the strategy to be applied so that an industrypossesses characteristics of competitive advantages that can survive/win business competition.As a new area, Gorontalo Province requires a scale of priority that can be made as a referenceand industrial development plan in the future. The research model constitutes the results ofseveral models of competitive priorities that have been established in several new industrializedcountries; meanwhile the research object was focused on Small Medium Industry (SMIs)considering that SMIs are the biggest industrial group in Gorontalo Province. Based on thesurvey and results of data processing using. The Law of Comparative Judgment (LCJ) method,there are 7 (seven) dominant dimensions that should be considered in developing industry;namely, Quality, Cost/Price, Delivery, Customer Focus, Flexibility, Innovativeness and MarketOrientation. This order of competitive priorities can also be applied in other areas consideringthat the characters of SMI that are the object of the research are in principle the same as thoseof the SMI in other areas of Indonesia.

Full textAbstract:
The article reflects some of the results of the author’s research on improving the accuracy of statistical assessments of inter-regional differences in the standard of living of the Russian population. Regional differences that have taken place over the past 15 years in the Russian Federation are measured using important indicators of living standards such as average per capita monetary income and final consumption per capita. The author states that the inter-regional differences in the period under review, although present, were quite small and relatively stable over time. Treatment of the results from international comparisons conducted under the auspices of the OECD and according to the author’s calculations related to a set of Russian regions confirms the presence of the Balassa-Samuelson effect. The adjustment of indicators under review to the territorial price index is carried out, as a result of which the level of differentiation of regions becomes noticeably lower, in full accordance with this effect. At the same time, the order of regions in the series ranked by cost of living indicators changes slightly, which leads to the conclusion that the reduction of differentiation by taking into account inter-regional differences in the price level is mainly due to the compression of the range of changes in the monetary indicators of living standards. To check the adequacy of the obtained conclusions, a comparative inter-regional analysis was carried out using some indicators that reflect the standard of living, such as per capita consumption of meat and meat products, housing security, and average life expectancy at birth. To obtain a comparative benchmark for the same set of differentiation measures, differences in living standards are measured for the aggregate of countries in the world as a whole and the aggregate of EU countries in particular. According to the author, the comprehensive use of methods and techniques for inter-regional statistical analysis of the well-being of the population confirms a positive trend in the implementation of one of the directions of current Russian socio-economic policy.

It is very important to estimate real estate very exactly in order to choose the right way of investment and to choose strategy of building purpose after restoration. While evaluating the variants of investment into real estate, practically we can meet the problem of establishing the index weight. Subjectivity is inevitable, and having inquired a sufficient number of specialists, we could find real weight of indexes. We have arranged an inquiry for real estate evaluators, specialists of real estate marketing, construction specialists and researchers and formed out the comparative weights of indexes which have the greatest influence on real estate marketing. The aim of the inquiry was to establish the index weights, which would help to choose the most profitable variant. The situation was investigated where the building was bought, repaired and used for some purposes; later it was rented or sold. The general model of reconstruction marketing is given in Fig 1. At the beginning some buildings are chosen for investment. Before buying one of them it must be estimated. There are things that must be taken into consideration: the amount of structures, the degree of wear, the location. Some variants of building utilisation are designed. For example, we can arrange flats, a café or a hotel in the structure. An estimate for each structure must be made. When all the necessary expenditure is found, market calculation should be performed: which variants are cheaper, what profit could be gained having rented or sold the structure, what price of selling must be for having the invested means back and for gaining the foreseen profit. For comparison, possible selling price is estimated. If the credits are to be taken, the stages of credit taking and investment as well as the growth of interes must be foreseen. The best variant is selected according to the best ratio of the means invested and the profit gained. The next stages of activities—the structure is renovated, sold or rented. Having calculated the realisation costs of each variant, the most favourable variants of investment are chosen with the help of expert methods. For the comparison of constructions and their utilisation, a questionnaire for experts has been compiled. It was devoted for establishing the importance of the indexes according to which the variants of investment are estimated. 18 experts took part in the inquiry. Having analysed the questionnaire filled by the experts, the common questionnaire has been arranged with the average meanings of numbers given by the experts (Table 2). The questionnaire is worked out according to twin-comparison method (using program KVADR, arranged at VGTU) and the vector of index importance is gained (Table 1). Then, the way of conciliation of experts' opinions is checked. Having worked up all the experts' questionnaires according to twin-comparison method, the vectors of index importance are gained (Table 3). The priority of indexes established by the experts is shown in Table 4. Having got the vectors of index importance, the coefficient of concordance can be found according to EXPERT programme [1] (author L. Ustinovičius). In case of calculation the importance of concordance coefficient x=64.44, when its normative meaning xnorm=26.22. Therefore the experts opinions are reconciled and can be trusted. The compared indexes lined up in order are shown in Table 5.

Full textAbstract:
The method of correction of maximum permissible values of breakdown voltage of transformer oils in order to minimize possible economic damage in case of making erroneous decisions during diagnostics of the condition of transformer oils according to the results of periodic tests is proposed. An algorithm for statistical processing of the periodic test results is described, the use of which allows forming arrays with homogeneous values of the indicators under a priori limited measuring information. Analysis of distribution laws of breakdown voltage values for the transformer oils suitable and unsuitable for operation according to the values of this indicator is done. According to the results of the analysis, it was found that the breakdown voltage values of oils with different states have Weibull distribution. It was determined that the values of mathematical expectations of breakdown voltage of serviceable oils with the ageing of transformer oils shifts to the area of low values. It means that the breakdown voltage maximum permissible values of oils for the given distributions should be different. It is confirmed by the previously known fact that for unimodal distributions, the maximum permissible values of indicators that provide a minimum of risk are in an interval bounded by the mathematical expectation of the indicator distributions with different states. A decisive rule is formulated and an average risk function is compiled to adjust the maximum permissible breakdown voltage values of transformer oils. Based on the minimisation of the average risk function by Newton's method, the maximum permissible values of the breakdown voltage of oils have been determined. The made comparative analysis has shown that the correction of maximum permissible values of breakdown voltage of oils allows decreasing the risk values by 1.52÷19.13 times in comparison with risks, which provide the use of maximum permissible values, regulated in standards. It was found that the maximum permissible values of the breakdown voltage of oils, providing a minimum value of average risk, are not constant. They vary depending on the values of faulty decision prices and the probabilities of occurrence of different defective and defect-free oil states of transformers.

Introduction. The article discloses the content of certification of wood pellets as a necessary component of its distribution through export. The comparative characteristic of wood pellets' technical parameters according to various European certification systems (DIN plus, EN plus A1, EN plus A2, EN-B) is presented. The scheme of the process chain for creating the value of biofuels with the distinction of main processes (production, sales and end energy use) is substantiated. The tendencies of price changes on wood pellets during 2011-2017 are analysed. The range of the main consumers of pellets in Ukraine is outlined. As a result of the analysis, proposals have been provided for adjusting the strategy of management of wood pellet production in order to standardize products and increase the sales efficiency on this basis. Purpose. The article aims to justify the need for certification of wood pellets, which are manufactured by domestic enterprises on the basis of consumer demand analysis and trends in the development of the European market for wood pellets. Method. The article uses standard methods of scientific research, such as systematization, processing, data summation, definition of generalized synthetic indices, presentation of the obtained results in the form of statistical tables, graphs and figures. The methodology of the Ukrainian Pellet Union is used to create a profitability algorithm based on certification. Results. The conclusions, which have been made in the article, prove that some characteristic features influence the distribution process of the wood pellets by enterprises. It has been investigated how product certification “adjusts” an effective system of sales at the enterprise. The results and recommendations, which have been described in the article, can be used by producers of wood pellets with completed cycle of value creation.

Abstract Research undertaken by the World Bank in Europe and the Central Asia Region indicates that there are four principal preconditions for introducing value-based recurrent property tax reforms: comprehensive property registration, a reliable source of data about the prices achieved in transactions, a valuation infrastructure that complies with internationally-recognized standards, and an efficient tax collection system. In spite of the arguments in favor of value-based recurrent property taxes, many countries raise revenue from recurrent property taxes using an area basis, and most countries raise relatively little revenue from recurrent property taxes. The paper has been written according to both the dogmatic-legal method and comparative method. It presents current solutions adopted in post-Soviet European countries in order to draw out recommendations and suggestions for Poland. The original reasoning for the paper is that, amongst many scientific papers concerning thorough debate of property tax systems, few have focused on post-Soviet countries and the issues that arise in transition countries. Most concern Western European or North American countries with different economies, politics, institutions, and histories to the Eastern ones. Authors of the paper believe that the article can fill the gap in discussions on the shape of the property tax system reform in Poland and the reforms carried out in Eastern Europe countries.

Full textAbstract:
According to many scientists a brand is one of the most important sources of acquiring competitive advantage. This attitude is confirmed by the fact that there are many scientific works on brand image. But there is a lack of theoretical and empirical research on the formation and strengthening of an image of a private brand. It should be noted that theoretical and empirical research, performed by Reda (2002), Ailawadi et al. (2003), based on Batra and Sinha (2000), Garretson et al. (2002), Burton and Lichtenstein (1998), confirm that factors that influence the formation and strengthening of the image of a private brand have not been sufficiently analysed. The scientific problem of this article is formulated with the help of the following questions: what is the influence of a store’s image and factors that determine it on the image of a private brand? The aim of this article is to analyse and summarize factors that form private brand image theoretically, and to test them empirically with the help of the example of the store “Aprangos galerija”. The methods of comparative analysis of scientific literature and systematization were used in order to reach the set aim. Quantitative research method (survey) was applied for empirical research of private brand image strengthening in the aspect of the store “Aprangos galerija”. Factor analysis was used for data analysis. Multiple linear regression was used for identification of causalities between variables. Based on the analysis of scientific literature, having summarized the results of the performed theoretical and empirical research it is stated that one of the sources of competitive advantage for stores is the creation of a positive and strong private brand image in consumers’ consciousness. It should be noted that brand identity elements and associations, related to the product itself and its perceived quality and emotions, form a positive private brand image. Having revealed the conceptual essence of an image, having analysed the structure of a company’s image, having identified factors that determine a store’s image and based on the results of scientific theoretical and empirical research it is stated that a store’s image depends on the following factors: services, convenience, quality, product variety, product prices, and store atmosphere. The results of the performed empirical research have shown that factors forming a store’s image (convenience and store atmosphere) have the biggest influence on a positive private brand image. It should be noted that factors determining a store’s image such as product variety and price also form a positive private brand image. Based on theoretical provisions and results of empirical research a conclusion is made that in order to strengthen a private brand image it is necessary to make decisions related to the store’s place, atmosphere, stock formation, and pricing.DOI: http://dx.doi.org/10.5755/j01.ee.23.1.1227

The article is concerned with the issues of assessing the intellectual property rights as part of intangible assets of enterprises. The article is aimed at substantiating the theoretical principles and improving methodological approaches to the assessment of intangible assets in the process of formation of the value of enterprise. The normative-legal regulation of valuation of intangible assets in order to determine the value of intangible assets of enterprises in monetary terms for the purposes of accounting and in the field of professional valuation activity is studied. The interrelationship of approaches of independent professional estimation and accounting valuation in order to apply it to the needs of accountance is specified. Described are the cost (based on determining the cost of expenses, necessary for the reproduction or substitution of the valuation object), profit (used to determine the valuation of intellectual property rights, based on the application of assessing procedures for transferring the expected profit to the value of the assessed object) and comparative (determines the market value of an intangible asset, when there is sufficient reliable information on prices in the market of such objects and the terms of contracts for the disposal of property rights to such objects) approaches to the valuation of intangible assets. The formulas for computing the value of intangible assets based on the cost approach are provided. The assessment of intangible assets is carried out according to the above specified formulas of the cost approach on the example of a patent for invention. It is determined that in the absence of an active market to determine the fair value of intangible assets, it is advisable to apply the cost approach, namely: the method of direct reproduction.

This thesis deals with a comparison of the market prices of Brno family houses. The compared prices are estimated using the comparative way based on the price regulations and using the comparative method. A new coefficient for the comparative method is proposed in the thesis. This coefficient takes into account the influence of the distance of the estimate property from the city centre in the connection with the position. One of the main reasons to introduce this coefficient was to obtain the best result when estimating the price, the result which is the closest to the required market price. The use of the coefficient of the global position may lead to better results of the price estimate, especially in bigger cities where this influence is revealed the most.

Gold is not only an ornament but also used for an alternative financial instrument of microfinance in emerging economies. The purpose of this chapter is to determine the effects of economic imbalances on gold prices in Turkey as a case of emerging economies. Using the monthly data of eight relevant variables for the periods between 1995:7 and 2016:5, a new model is created by using MARS (multivariate adaptive regression splines) method in order to achieve this objective. The results show a negative relationship between gold prices with interest rate of TL and USD and increase in USD currency. The main results demonstrate that investors need the microfinance and the individual suppliers of finance could prefer gold for the financial investment or index their financial sources obtained from the individual investor according to the changes of gold prices. Furthermore, it also concludes that high inflation rates lead to increase in gold prices and mostly affect the microfinance possibilities.

Full textAbstract:
The era of cloud computing allowed the instant scale up of provided services into massive capacities without the need for investing in any new on site infrastructure. Hence, the interest of this type of services has been increased, in particular, by medium scale entities who can afford to completely outsource their data-center and their infrastructure. In addition, large companies may wish to provide support for wide range of load capacities, including peak ones, however, this will require very higher costs in order to build larger data centers internally. Cloud services can provide services for these companies according to their need whether in peak load capacity of low ones. Therefore, resource sharing and provisioning is considered one of the most challenging problems in cloud based services since these services have become more numerous and dynamic. As a result, assigning tasks and services requests into available resources has become a persistent problem in cloud computing, given the large number of variables, and the increasing types of services, demand, and requirement. Scheduling services using a limited number of resources is problem that has been under study since the evolution of cloud computing. However, there are several open areas for improvements due to the large number of optimization variables. In general, the scheduling of services on available resources is considered NP complete. As a result, several heuristic based methods were proposed in order to enhance the efficiency of cloud systems. Since the problem has several optimization parameters, there are still several improvements that can be done in this area. This chapter discusses the formalization of the problem of scheduling multiple tasks by single user and multiple users, and then presents a proposed solution for each individual case. First, an algorithm is presented and evaluated for optimum schedule that allocates a number of subtasks on a given number of resources; the algorithm was shown to be linear vs. number of users. Then, an algorithm is presented to address the problem of multiple users allocations, each, with multiple subtasks. The algorithm was design using the single user allocation algorithm as a selection function. Since, this problem is known to be NP complete, heuristic based methods are usually used in order to provide better solutions. Therefore, a green evolutionary based algorithm is proposed in order to address the problem of resource allocation with large number of users. In addition, the algorithm presents allocation schedule with better utility, while the execution time is linear vs. different parameters. The results obtained in this work show that it overcomes the outcome of one of the most efficient algorithms presented in this regard that was based on game theory. Further, this method works with no restrictions on the problem parameters as opposed to game theory methods that require certain parameters restrictions on cost vector or compaction time matrix. On the other hand, the main limitation of the proposed algorithm is that it is only applicable to the scheduling problem of multiple tasks that has one price vector and one execution time vector. However, scheduling multiple users, each with subtasks that have their own price and execution time vector, is very complex problem and beyond the scope of this work, hence it will be addressed in future work.

<p>Finite element (FE) model updating of civil engineering structures is usually performed under the modal domain. According to this approach, the value of the main physical parameters of the structure is modified in order to reduce the relative differences between the experimental and numerical modal parameters of the structure. To date, two methods are widely used to perform the FE model updating: (i) the maximum likelihood method and (ii) the Bayesian method. The second method is usually implemented via sampling methods. Thus, the FE model updating consists in determining an efficient sampling of each considered physical parameter of the model. Herein, two sampling techniques, the Metropolis-Hastings (M-H) algorithm and the Slice Sampling (SS) algorithm, are compared when they are implemented for the FE model updating of a laboratory steel footbridge.</p>

Full textAbstract:
Due to many advantages of using natural resources, natural fibers have been used recently as a method of providing added strength and ductility to reinforced polymer composites. This is mainly due to their availability, renewability, low density, cost effectiveness as well as satisfactory mechanical properties. This paper presents fabrication and experimental characterization analysis of mechanical properties of a class of bio-composite in which polypropylene (PP) and low density polyethylene (LDPE) are reinforced with date palm frond fibers. Bio-composite sheets were fabricated with controlled processing parameters based on small factorial design in order to develop a statistical model for response using fractional design of experiment. In a Design of Experiment (DoE) procedure, we identify three different factors along with three different levels; fiber volume fraction (20, 40, and 60 vt. %), alkali treatment (10, 15, and 20 Wt. %), and treatment time (2, 4, and 6 h). In this study, NaOH alkali solution is used to modify the fiber properties and improve surface characteristics. The tensile and flexural strengths of specimens prepared according to ASTM standards were measured by direct physical testing. Also, the Response Surface Methodology (RSM) is adopted to analyze interactions among the input factors and their effect on overall mechanical properties of the fabricated composite. Results revealed that fiber length and percentage of NaOH treatment have a significant impact on the composite properties. The date palm frond reinforced polypropylene composites could serve as a potential material in broad range of industrial applications in which high strength is not a main design requirement.

Full textAbstract:
The paper aims at quantifying the changes in notional reliability levels that result from redesigning an existing suezmax tanker to comply with new Joint Tanker Project (JTP) rule requirement for ultimate vertical bending moment capacity. The probability of structural failure is calculated using a first-order reliability method. The evaluation of the wave-induced load effects that occur during long-term operation of the ship in the seaway is carried out in accordance to IACS recommended procedure. Comparative analysis of long-term distributions of vertical wave bending moment calculated by two independent computer seakeeping codes is performed. The still water loads are defined on the basis of a statistical analysis of loading conditions from the loading manual. The ultimate collapse bending moment of the midship cross section, which is used as the basis for the reliability formulation, is evaluated by JTP single-step procedure and by program HULLCOLL for progressive collapse analysis of ship hull-girders. The reliability assessment is performed for “as-built” and “corroded” states of the existing ship and a reinforced design configuration complying with new JTP rules. It is shown that hull-girder failure probability of suezmax tanker reinforced according to new JTP rules is reduced several times. Sensitivity analysis and a parametric study are performed to investigate the variability of results to the change of parameters of pertinent random variables within their plausible ranges.

Full textAbstract:
The main aim of this study is to identify the main development problems and the affecting factors of the agricultural sector of Kyrgyzstan. In order to achieve the goal, the relationship between the agricultural sector’s export, import, the employment rate and the amount of loans granted to the agricultural sector was analyzed by the ARDL cointegration method. Annual data for the period 1992-2014 was used in the analysis. According to the empirical results, a 1% increase in exports was found to increase agricultural production by 0.23% in the short term, while a 1% increase in the price index of agricultural products would increase production by 0.41%. In the long run it has been revealed that the production of agricultural products is affected by the increase in prices of agricultural products, the employment rate and the exports of agricultural products. The effect of the bank loans is weak. As a result, the state must implement an appropriate pricing policy in order to develop the agricultural sector.

The storage tanks in nuclear facilities has a significant impact on the safety of the reactor and the radiation shielding, so its mechanical property analysis has been widely concerned in the field of engineering and scientific research. Meanwhile, the storage tank is usually filled with gas and liquid medium. In the presence of external disturbances (such as external force, displacement, earthquake etc.), the position and structure of the vessel changes, that lead to changing of the gas-liquid interface. This characteristic can make the storage tank system as a tightly fluid-structure coupling system. In this paper, a storage tank which stored radioactive gas liquid medium is choosing to study such fluid-structure coupling system phenomenon, and a typical dynamic seismic condition is assumed. A two-way fluid-structure coupling method is used with CFD (Computational Fluid Dynamics) and FEM (Finite Element Method) numerical method. The study considered interaction between structure and two phase turbulent fluid. In FEM calculation, the time history seismic acceleration load is applied to the support of tank, and the flow loading coming from fluid medium is applied to the wall of tank which is send from CFD code. Then, the structure displacement which is calculate by FEM is transferred to CFD code. In CFD calculation, multiphase fluid numerical model is applied to simulate the flow characteristics of gas-water two phase fluid, and the turbulent properties are also considered in the calculation. Mesh deformation method is used to simulate the displacement of flow passage boundary which is send by FEM code. After CFD calculation, flow loading is transferred to the tank wall of FEM code again. Such loop of FEM and CFD calculation continues to go on with the seismic time history, the response characteristics of the tank will be solved. In order to evaluate the difference between the above method and the traditional analysis method. An independent calculation used added mass approach is carrying out, in which the effect of steady state water is applied to the wall of the vessel, and this load will not change with the earthquake. All others load and constraint mode are same with the above method. According to the two-way fluid-structure coupling analysis, the detailed characteristics of liquid free surface distribution and structural response of the vessel are obtained. The results show that the response vibration amplitude of the tank structure increases with the earthquake, and the response is mainly affected by the liquid sloshing. According to comparative analysis, the advantages of coupling method are proved. The method from this study can be used for the same type of analysis.

Earth and rock are the principal materials from which dams are constructed, these kinds of dams are called embankment dams. The conventional limit equilibrium method has dominated use over any other method for analyzing slope stability. In this paper, Spence, Morgenstern-price, the Ordinary method of slices, and Janbu simplified methods are used in order to find out how near, far Aquban dam from the verge failure which is located in Erbil-Kurdistan/Iraq. In present study, the focus is mainly drawn on analyses of steady-state condition. To compute the factor of safety, the study utilized SLOPE/W software. The results show that there is no major difference in a safety factor and a critical slip surface position between all the methods which are used in the study. In addition, all used methods offered a more than the minimum required safety factory which is given by the U.S. Army Corps of Engineers so this ensures that the dam against slope instability is on the safe side. According to the results obtained from this study, Janbu simplified method which considers only force equilibrium condition produced the lowest factor of safety, while the highest and almost identical factor of safety generated from the methods that satisfy all the static equilibrium condition (Spencer and Morgenstern-Price methods) give. Therefore, a reasonably reliable and higher value of safety factor is given by the methods which satisfy all static equilibrium conditions.

In ASME 2010 International Mechanical Engineering Congress and Exposition. ASMEDC, 2010. http://dx.doi.org/10.1115/imece2010-39050.
Full textAbstract:
The use of high speed radial impellers is very common in fans for industrial applications. The most common design case is the one with constant speed. In that case, one assigns the corresponding value to the speed n, hence the speed no longer matters in the further design procedure: it is given and it is constant. However, in many cases the speed is not constant, since it is governed by the torque-speed characteristic of the driving motor. In such a case it is necessary to consider the motor characteristic already at the design stage. In the present work a design method was developed in order to perfectly match the torque-speed characteristic of the radial impeller to the torque-speed characteristic of the driving motor. In such a way it is possible to design an impeller-motor unit with maximum efficiency. The extended impeller mean-line-design formulas presented in Epple [6] were complemented with the equations describing the motor torque-speed-characteristic. Both sets of equations where combined and solved in order to achieve a prescribed operating range at a maximum efficiency. In order to validate the design method, it was applied to an industrial fan which should be improved. That radial fan with spiral casing consisted of the main radial fan and a motor cooling axial fan at the other end of the shaft. This later fan was rotating at a too low speed leading to cooling problems of the motor. Hence, a new fan had to be designed which had to deliver the same hydraulic performance but at higher rotating speeds. This had to be done, however, on the given motor. That could only be done when properly designing an impeller matching its torque-speed characteristic to the torque-speed characteristic of the motor: it was an excellent task to validate the combined impeller-motor design procedure. Under these constrains six designs where performed and validated with a commercial CFD solver. The three best designs according to the CFD results were built as prototypes and measured at a standard test rig. The best design delivered the prescribed head-flow characteristic at an even improved hydraulic efficiency. The higher speed was also properly achieved. The design procedure is described and explained in detail and a detailed CFD analysis is presented, complemented by the experimental data obtained at the test rig. A final comparative analysis of the combined impeller-motor design method, the CFD analysis and the measurements is presented.

The distributed absorption cooling based district heating system was investigated in order to utilizing the reject heat from the combined heat and power (CHP) plant in summer. Compared with the electric compressor cooling, the energy efficient and cost-effectiveness of the distributed absorption cooling were furthermore analyzed by the Fuel Energy Saving Ratio (FESR) method. The sensitivity of some variables, such as the average electric efficiency, heating and electric generation efficiency of the CHP system, and the coefficient of performance (COP) of the chiller, were analyzed. The marginal heating price of the distributed absorption cooling can be obtained. According to the evaluation results, the applicability of the distributed cooling with district heating system is limited by the lower energy efficiency and economical benefits. The approaches to increase the energy efficiency were suggested in this paper. The improved distributed absorption cooling combined with liquid desiccant dehumidification which has higher heating utilization efficiency was put forward and analyzed, and the energy efficiency evaluation results showed that the improved distributed cooling has higher energy efficiency and economical benefits, and great applicability.

In 2020 13th International Pipeline Conference. American Society of Mechanical Engineers, 2020. http://dx.doi.org/10.1115/ipc2020-9517.
Full textAbstract:
Abstract A reliability-based limit states design (LSD) method for assessment of corrosion and crack features has been developed for onshore transmission pipelines as part of a joint industry project. The rule-based LSD approach is a simplified form of the reliability-based approach that reduces the latter to a set of deterministic checks. The LSD corrosion assessment method and a comparison of its performance against one operator’s reliability approach were published in previous IPC papers [1,3]. This paper compares the LSD corrosion and crack assessment methods to another simplified reliability-based approach, namely the Pipeline Integrity Reliability Analysis (PIRA) Level I, that was published in a previous IPC paper [2]. The PIRA model is staged into three levels, where Level I analysis is a simplified form of the reliability-based approach where the probability of failures of predefined features’ sizes are precalculated using conservative assumptions for a fast turnaround screening analysis of the entire pipeline system in order to identify areas requiring more in-depth full probabilistic Level II or III analyses. This paper describes the application of both LSD and Level I methods on two low vapour pressure (LVP) liquid pipelines and provides a comparison of the results. The comparative analysis was based on the number of features not meeting reliability targets in both methods and, thus, are eligible for repair according to each method. Out of the two pipelines considered, one has corrosion and the other has cracks as the dominant threat. The results show that there are noticeable differences between the outputs of the two methods. The root cause of these differences was investigated by conducting a sensitivity analysis on the input parameters, including: reliability target, wall thickness distribution, feature depth and length distributions, pipeline sectioning procedure and the usage of model error (which is used in the LSD method but not in the PIRA Level I method). For cracks, differences between the Modified Ln-Secant model used in the LSD method and the CorLAS model used in PIRA Level I were also considered. It was observed that the discrepancies in the required repairs resulting from the two methods can be mostly attributed to the feature depth distribution, wall thickness distribution and the reliability target. For cracks, the burst pressure model selection also had a significant impact on the results.
