Abstract Model-based optimization is a sophisticated design tool for papermaking processes. In this paper, the method is extended from the unit process design and single-level optimization to the simultaneaus design of the process structure and operations. This is enabled by using a bi-level optimization formulation which allows to avoid unnecessary iterations between the process and automation designs. The bi-level optimization approach is studied here from the perspective of multiobj ective optimization and decision making. The method is illustrated by a case study in which the broke and water system structures and the papermaking process operations are optimized simultaneously.

This study examined Indonesia's education unit level adoption of the Contextual Teaching and Learning approach and its supportive and limiting elements. In the Education Unit Level Curriculum, Contextual Teaching and Learning works well. To make learning more relevant and the Education Unit Level Curriculum implementation successful, implementation must be context-based. The Unit Level Curriculum must match students, educators, learning media, the environment, and their natural traits. Because this must follow the method to attain educational goals. Thus, Contextual Teaching and Learning depends on the Education Unit Level Curriculum. To support and balance each other, the Unit Level Curriculum socialization process for instructors must function properly. If the Education Unit Level Curriculum implementation goes successfully, the Contextual Teaching and Learning approach will be the same

In today’s chemical, refinery, and petrochemical sectors, separation tanks are one of the most significant separating processes. One or more separation tanks must operate consistently and reliably for multiple facilities’ safe and efficient operation. Therefore, in this paper, a PI controller unit has been designed to improve the performance of the tank level controller of the industrial process in Basrah Refinery Station. The overall system mathematical model has been derived and simulated by MATLAB to evaluate the performance. Further, to improve the performance of the tank level controller, optimal PI parameters should be calculated, which Closed-Loop PID Autotuner has been used for this task. Several experiments have been conducted to evaluate the performance of the proposed system. The results indicated that the PI controller based on the Autotuner Method is superior to the conventional PI controller in terms of ease to implement and configuration also less time to get optimal PI gains.

Abstract Unit level traceability (ULT) is a powerful tool that allows complete die histories to be accessed in the course of testing and analysis. It is especially useful for identifying the likely causes of microprocessor failures and in cases where failure analysis resources are limited. In the article, the author explains how he used ULT in the investigation of a 0.25-µm CMOS processor. Using the ULT of the die, he discovered a failure signature based on die location on the wafer. One root cause of failure was traced to cross-field variation in the lithography process due to marginal focus control. Another failure, observed after burn-in, was traced to the presence of residual titanium left after metal etch.

The increase in demand for mobile telecommunication systems, and the limited bandwidth allocated to these systems, have led to systems with smaller cell dimensions, which in turn led to the increase of control messages. In order to prevent controller bottle necks, it is desirable to distribute the network control functions throughout the network. To satisfy this requirement, a mobile network structure characterized by its hierarchical and decentralized network control is presented in this paper. The area served by the mobile system is divided into regions, and the regions are further divided into cells. Each cell is served by a base station, each base station is connected to a regional network through a base station interface unit (BIU). Each region has its own regional network. Connected to each regional network are the cellular controller, the home database, the visitor database, the trunk interface unit (TIU) and the gateway interface unit (GIU). The TIU connects the regional network to the public switched telephone network (PSTN). The GIU connects the regional network to other regional networks through the gateway network. This architecture distributes the network control functions among a large number of processing elements, thus preventing controller bottle necks — a problem faced by centralized controlled systems. The information and network control messages are transferred in the form of packets across this network. Processes inherent to the operation of this network structure are illustrated and discussed. These processes include the location update process, the setting up of a call, the handoff process (both the intra-region handoff process and the inter-region handoff process are considered), and the process of terminating a call.

The elaboration and introduction of the new high-energetic and resource effective equipment in the activity of food industrial enterprises, including restaurant economy is an urgent scientific problem. The most important role at that is played by the unit energetic consumption of energetic processes, which decrease allows to receive an economic effect. The rise of the energetic effectiveness of technological processes of fried meat products manufacturing is possible at the expanse of combining traditional and non-traditional (physical and electrophysical) processing methods. The use of combined thermal processing methods allows to raise the effectiveness of heat conduction from heating environments to a product. The aim of the research was the determination of the frying surfaces temperature at the bilateral heat supply for a value of the mean integral temperature pressure and frying process duration, ready product output and unit energy consumption. The change of the initial temperature level of the frying process has an essential influence on the mean integral temperature pressure between a frying surface and product surface layer. The temperature decrease of frying surfaces from 423 К to 393 К leads to the decrease of the mean integral temperature pressure between a frying surface temperature and product surface one by 4 К by the nonlinear law, and allows to raise the coefficient of heat conduction through steam layers. It was proved, that the bilateral frying of natural products of meat at the surfaces temperature 393 К allows to decrease the process duration by 6 s, to raise the ready product output by 3,3% and to decrease the unit electric energy consumption by 0,023 kW·hour/kg comparing with the bilateral frying at the surfaces temperature 423 К.

This paper discusses preventive replacement policies for an independent damage process, in which successive shocks occur at random times, and the independent damages caused by shocks are random variables. It is assumed that a unit fails when the damage has exceeded a prespecified level [Formula: see text]. We consider three models: Model 1: the unit is replaced at the [Formula: see text]th shock for damage [Formula: see text], at damage [Formula: see text], or at time [Formula: see text], whichever occurs first. Model 2: the unit is replaced at the [Formula: see text]th shock for damage [Formula: see text], at damage [Formula: see text] or at shock [Formula: see text], whichever occurs first. Model 3: the unit is replaced at the [Formula: see text]th shock for damage [Formula: see text], at damage [Formula: see text], at shock [Formula: see text] or at time [Formula: see text], whichever occurs first. We obtain the expected cost rates for each model and discuss analytical optimal [Formula: see text] and [Formula: see text] to minimize their expected cost rates. Numerical examples are given when the damage has an exponential distribution and shocks occur at a gamma distribution.

The goal of this article is to present qualitative and quantitative reviews of servant leadership literature since its formal inception in 1970. Summarizing previous studies, we theorized and explored issues concerning the conception and relevance of servant leadership, the merits of varied measurements, issues concerning construct dimensionality, and the potential effects of national culture on the relationship between servant leadership and its correlates. We developed theory to distinguish servant leadership from competing leadership theories of transformational leadership and leader-member exchange (LMX) theory and examined the direct and the incremental influence of servant leadership on individual and unit-level outcomes. To consolidate extant research and to guide future theory development we tested a mediational process model linking servant leadership to outcomes. Meta-analytic results supported distinctiveness of servant leadership, showed effects of servant leadership on individual-level and unit-level outcomes, and supported theorized mediating effects of trust and fairness perceptions in the relationship.

Fanout Wafer Level Packaging (FoWLP) is a very attractive solution for microelectronics applications requiring optimized performance, smaller form factor, and low cost. By utilizing such an approach where system integration is done to multiple chips on a single package frame, the need to ensure much higher levels of process integrity, quality, and reliability becomes absolutely critical, especially if the total product volume lies in the range of tens of millions of units. A single defect type may negate the benefits of such an approach because the cost of losing one FoWLP unit results in the loss of multiple devices. Thus, yield, quality, and reliability optimization using such a package solution is critical for successful large scale manufacturing. In this talk, the issue of defectivity and its impact on quality and reliability on Wafer-Level (WL) devices with regards to the issue of Die Edge Delamination (DED) and Chip Mechanical Integrity (CMI) is discussed. Through this discussion and the resulting solutions found to improve WL quality and reliability, better understanding on how to assess the quality and reliability of a given FoWLP solution for large scale production will be demonstrated.

The limitation on the level of phenolic compounds in industrial waste water requires from Nitroclor the treatment of the mother liquors coming from its nitrophenols production unit, previous to sending them to biological treatment. The literature and the accumulated experience during the last years show that nitrophenolic compounds removal at high temperatures is potentially dangerous due to the thermal instability characteristic of these products. It was developed a new process minimizing the thermal risks and recovering nitrophenols with high purity.

Advanced design power units are distinguished by a high degree of digital transformation. Therefore, of particular interest are operator information (intelligent) support systems, which can reduce the workload on operating personnel as well as predict possible deviations long before they evolve into severe emergencies. The article analyzes the current standard process documentation that requires solutions to support the operator and determines the list of system functions that should be provided to improve the safety level of nuclear power plants. A brief overview of the world experience in implementing such solutions is also provided. As an example of the further development of operator support systems, the authors consider the operator information support system (OISS), which is being developed at the NvNPP pilot unit with the VVER-1200 reactor. The OISS functions will make it possible to fulfill the requirements of standard process documentation that are currently not implemented in the power unit design. The key features of the OISS under development are step-by-step interactive procedures and the unit software model. The authors provide a brief description of the power unit software model and consider several examples of its practical application as part of the OISS to improve design solutions and optimize automatic process control. In the years ahead, it is proposed to implement the OISS at power units under construction in order to reduce the information overload of operators and create conditions for a step-by-step increase in the automation level of the power unit control.

Purpose The purpose of this paper is to examine how transformational leadership may relate to corporate entrepreneurship by adopting a multilevel approach. The authors also theorized and tested the top-down and bottom-up intermediate process linking transformational leadership and corporate entrepreneurship. Design/methodology/approach Multisource data across different timeframes were collected from 129 managers and 244 employees from 55 units of 27 firms. Findings The results showed that transformational leadership and corporate entrepreneurship were positively related at the unit level. Furthermore, unit-level collective efficacy mediated the relationship between unit-level transformational leadership and unit-level corporate entrepreneurship. The authors also found that the firm-level empowerment climate moderated the indirect effect of unit-level collective efficacy on the relationship between unit transformational leadership and unit-level corporate entrepreneurship. Originality/value First, the goal of this study is to extend the single focus of transformational leadership on corporate entrepreneurship (e.g. Ling et al., 2008) and develop a more thoughtful approach on determining how transformational leaders influence corporate entrepreneurship across levels. This study responds to calls for research to look at the impact of unit-level transformational leaders, such as middle managers, across levels (Ren and Guo, 2011) and creates a multilevel framework in which transformational leaders at the unit level influence the appearance of corporate entrepreneurship at the unit level.

Texto completoResumen
Bodies of territorial public self-government (TPSG) are one of the key participants in the strategic planning process at the municipal level. These organizations make an important contribution to achievement of sustainable development goals of the municipality. Territorial public self-government bodies are not the driving force behind the development of the municipal economy. However, they are able to solve the problems of social development of the territory by using the resources of self-organization. The existing potential allows TPSG bodies not only to participate in the development of strategic documents, but also to take part in the implementation of specific projects. Participation in the project can be carried out both in a non-financial form (labor) and in a financial form (based on the results of use of self-taxation, crowdfunding, fundraising, business income, and other sources). Therefore, it is extremely important for the authorities to involve TPSG bodies in strategic planning processes in order to improve the quality of final documents, as well as increase the efficiency of their realization. However, a number of factors hinder the successful involvement of bodies of territorial public self government in strategic planning processes. The established practice of involvement of public in managerial decision-making processes leads to a low interest of non-profit organizations in participation in such procedures. In addition, the level of development of educational infrastructure in the field of territorial public self-government does not allow the heads of territorial public selfgovernment bodies to achieve the sustainable development goals of the municipality territory, as well as to develop skills in organizational management within its borders. As a result of the introduction of a set of suggested measures in the regions, the conditions will be created for the territorial public self-government authorities to realize their potential fully, which will ultimately be reflected in the improvement of the quality of residents’ life.

The problems of controlling the operating modes of pumping units with a frequency-controlled drive based on an asynchronous short-circuited motor are considered. The specific features of the requirements for the control process quality indicators of liquid level stabilization control system for the reservoirs are discussed. Mathematical models of functionally necessary parts of the system are obtained in the form of transfer functions: a frequency-controlled drive with scalar control, a generalized control object, and a feedback sensor. The linearized model of the controlled object taking into consideration a nonlinear dependence of the the torque at the motor shaft on rotational speed is obtained in the form of a transfer function of the aperiodic unit. A block diagram of a closed loop liquid level control system has been developed. It is shown that the use of standard settings for the system under consideration, focused on maximum performance achievement, can leads to unacceptable values of control action speed variations and hence to generation of hydraulic shocks that decreases a wear of kinematic parts of the unit. A method for the synthesis of the controller is proposed, which takes into account the limitations on the quality indicators of the transient process of a speed variation of the pump unit when control system counteracts main disturbances. The synthesis of controller is carried out for an example of a specific installation and the results of modeling transients of a control system and perturbing effects are discussed.

Unit root tests for time series with level shifts of general form are considered when the timing of the shift is unknown. It is proposed to estimate the nuisance parameters of the data generation process including the shift date in a first step and apply standard unit root tests to the residuals. The estimation of the nuisance parameters is done in such a way that the unit root tests on the residuals have the same limiting distributions as for the case of a known break date. Simulations are performed to investigate the small sample properties of the tests, and empirical examples are discussed to illustrate the procedure.

AbstractIn the course of its history, English underwent a significant structural change in its numeral system. The number words from 21 to 99 switched from the unit-and-ten to the ten-before-unit pattern. This change is traced on the basis of more than 800 number words. It is argued that this change, which took seven centuries to complete and in which the Old English pattern was highly persistent, can be broken down into two parts—the reordering of the units and tens and the loss of the conjoining element. Although the two steps logically belong to the same overall change, they display a remarkably disparate behavior. Whereas the reordering process affected the least frequent number words first, the deletion process affected the most frequent words first. This disparity lends support to the hypothesis that the involvement or otherwise of low-level aspects of speech determines the role of frequency in language change (Phillips, 2006). Finally, the order change is likely to be a contact-induced phenomenon and may have been facilitated by a reduction in mental cost.

Abrasive waterjet (AWJ) machining is a non-conventional process. Its most striking advantage is the absence of a heat-affected zone. AWJ machining can be successfully used on a very broad spectrum of materials, regardless of their brittleness, ductility or composition. However, this machining process has the disadvantage of striations being left on the surface of the machined workpiece. Since forecasting of the results of this process is still on the empirical level, great efforts are being put into the modelling of the AWJ process. In this paper, an original model of the AWJ machining process is presented. It is based on an AWJ process unit event, which in this case represents the impact of a particular abrasive grain. The geometrical characteristics of the unit event are measured on a physical model of the AWJ process. The measured dependencies and the proposed model relations are then implemented in AWJ machining process simulation.

Introduction: One of the hazards caused by the process of producing plastic sacks is noise. Noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing. Noise is produced by machines used in the production process. Noise that exceeds the threshold limit value (TLV) at workplace can cause hearing loss. The purpose of this study was to analyze the hearing threshold level of workers who were exposed to noise in circulator loom unit at PT. Kerta Rajasa Raya Sidoarjo. Method: This was an observational study with a cross sectional approach. The population of this study was 47 workers, while the sample was the total population. The independent variable wasnoise, while the dependent variable was the hearing threshold level. Contingency coefficient was used to detemine the strength of correlation between variables. Noise intensity measurement at three points revealed that the value exceeded the time limit value. Result: Most of the workers were > 40 years old (72.3%), had work period of 15-20 years (51.07%) and never consumed ototoxic medication (80.85%). Conclusion: A moderate correlation between the noise intensity and hearing threshold level of right ear. However, the correlation between noise intensity and hearing threshold level of left ear is weak. Keywords: hearing threshold level, noise, work characteristic

For many time series in empirical macro and finance, it is assumed that the logarithm of the series is a unit root process. Since we may want to assume a stable growth rate for the macroeconomics time series, it seems natural to potentially model such a series as a unit root process with drift. This assumption implies that the level of such a time series is the exponential of a unit root process with drift and therefore, it is of substantial interest to investigate analytically the behavior of the exponential of a unit root process with drift. This paper shows that the sum of the exponential of a random walk with drift converges in distribution, after rescaling by the exponential of the maximum value of the random walk process. A similar result was established in earlier work for unit root processes without drift. The results derived here suggest the conjecture that also in the case when the Dickey-Fuller test or the KPSS statistic is applied to the exponential of a unit root process with drift, these tests will asymptotically indicate stationarity.

This study considers the supplier's warranty return and the buyer's rebate policy as business-return policy in the supplier–buyer supply chain. The policy as well as the displayed stock level influences the behavior of the buyer. Distinct from the traditional single-stage inventory model, we investigate a two-stage replenishment policy model for deteriorating item considering the effect of imperfect production process, product design, stock level and business-return. A mathematical model utilizing the time weighted inventory (TWI) approach and two-variables fixed point optimization technique is developed to derive the optimal inspection starting time, the number of deliveries, the optimal delivery-time interval and the optimal business-return period. A numerical example is presented to illustrate the model developed. The result shows that the fixed demand rate, the unit holding cost and the unit inspection cost are the critical factors affecting the scheduling and performance of the two-stage supply chain.

In today's world, it is of utterly importance for enterprises to react in a timely and flexible way to upcoming complex market demands. One solution is given by the concept of virtual enterprise and enterprise alliances, respectively. In order to function efficiently and flexibly such enterprises need to be deeply integrated. Based on previous work combining the concepts of virtual enterprises, holonic organizations and multi-agent systems to support such deep integration, the paper discusses in detail how well-suiting partners and contributors for a given (bunch of) task(s) can be found using today's state-of-the-art technologies. Mapping an enterprise alliance onto a multi-agent system is enabled by a methodology equipping each agent with the ability to deal and consider its own goals (goals of the unit it represents) as well as the goals of the unit in which it is integrated (the higher level unit).

Texto completoResumen
As an important indicator of flotation performance, froth texture is believed to be related to operational condition in sulphur flotation process. A novel fault detection method based on froth texture unit distribution (TUD) is proposed to recognize the fault condition of sulphur flotation in real time. The froth texture unit number is calculated based on texture spectrum, and the probability density function (PDF) of froth texture unit number is defined as texture unit distribution, which can describe the actual textual feature more accurately than the grey level dependence matrix approach. As the type of the froth TUD is unknown, a nonparametric kernel estimation method based on the fixed kernel basis is proposed, which can overcome the difficulty when comparing different TUDs under various conditions is impossible using the traditional varying kernel basis. Through transforming nonparametric description into dynamic kernel weight vectors, a principle component analysis (PCA) model is established to reduce the dimensionality of the vectors. Then a threshold criterion determined by theTQstatistic based on the PCA model is proposed to realize the performance recognition. The industrial application results show that the accurate performance recognition of froth flotation can be achieved by using the proposed method.

One of the main problems in grain production in China is the high level of unit costs (high cost price). The main reason is the low level of mechanization. Development of efficient technologies and means of mechanization is a promising area allowing to decrease the level of unit costs at a given labor efficiency and maintaining the achieved yield. Grain production is a complex system associated with a large amount of information: agro-technological (crop variety, crop yield, physical-and-mechanical parameters of land plots, terms of operations, permissible speed range for specific operations, etc.), technical-and-economic (power and traction parameters, throughput, working width, operating weight, hopper volume , cost). At present, efficient methods for studying complex systems have appeared as a result of development and widespread implementation of computer mathematics systems, which allow us to study mechanization technologies and tools using multi-factor modeling and multi-criteria optimization. The paper presents a multi-factor mathematical model, peculiar for the fact that the three groups of simultaneously varying factors are taken for the first time engine power, MTA speed, timing of the main energy-intensive operations – plowing, harvesting, and as conflicting optimization parameters unit cost level, coefficient of crop losses, labor efficiency, which allowed a comprehensive study of the grain production process in any natural-production conditions. A technological process has been developed (units speed and timing of the main operations (plowing, harvesting) and the corresponding range of machines and equipment, ensuring minimum level of unit costs at a given labor efficiency and maintaining the achieved crop yield, taking into account the specifics of the Middle China (2 crops per year).

When modeling an aeroengine control system, effects of fuel metering unit are neglected or oversimplified, which most probably leads to unreliable simulation or experimental results. In order to well understand influences of fuel metering unit on performance of an aeroengine and to enrich the component-level model of a turboshaft aeroengine, a stepping motor controlled fuel metering unit is examined by combining process-based modeling and object-oriented modeling and is employed in the component-level engine model. Performances of the engine with and without the fuel metering unit are compared by simulation. The component-level engine model with the fuel metering unit characteristics considered meets the simulation requirements on the steady precision and can describe dynamics of the engine more precisely. A semi-physical experimental verification is implemented to confirm the influence of the fuel metering unit. The results show that simulation using the component-level engine model with the fuel metering unit sub-model is in accordance with the experiment, and that comparing to the engine model without fuel metering unit, the model with a fuel metering unit can extend the performance parameter response dozens of milliseconds.

Because of the stochastic nature of production systems, it is necessary to first build an uncertainty model for subsequent real applications. Moreover, process parameter planning, quality design, and production inventory management are interdependent elements. In this research, a computer simulation model via computer-aided engineering (CAE) was developed to determine the optimal process parameters, lot size, and back order intervals for an integrated process design and inventory management system with simultaneous quality and cost considerations. Based on the estimated process time and costs obtained using CAE, the derived production rate and unit cost were then used for production inventory applications. In consideration of the uncertainty factor, the response surface method (RSM) was employed to analyze the output, namely the total costs incurred in employing the proposed approach, as well as the inputs, which include the cutting parameters, production quantity, and back order intervals. After the RSM was used to obtain the response functions, which represent the output of the collective interests, the mathematical programming (MP) was formulated based on the response functions to determine the optimal process parameters, process quality levels, production order quantities, and back order intervals. The total cost per set time unit was minimized by determining the required quality level, process parameter values, Economic Production Quantity (EPQ), and back order intervals. A cutting example was chosen to demonstrate the proposed approach. Two cases were used for comparison: the Integrated Case (the proposed approach herein) and the Disintegrated Case.
