Abstract:

New common platforms for optimization of balancing energy activation will facilitate cross-border exchange and integrate the fragmented European balancing markets. Having a zonal market structure, these platforms will optimize balancing actions as if intra-zonal transmission constraints did not exists, leaving it to each Transmission System Operator (TSO) to manage internal congestion caused by balancing energy activations. This paper describes a new method to pre-filter balancing bids likely to cause internal congestion due to their location. Furthermore, the complementary concept of exchange domains has been developed to prevent congested and infeasible balancing situations. A numerical example illustrates both the effectiveness and limitations of each method.

Abstract:

Background/Context This paper is part of the special issue “Reimagining Research and Practice at the Crossroads of Philosophy, Teaching, and Teacher Education.” In it we respond to the question of what role there might be for philosophy of education in an era marked by the demand that students graduating from teacher education programs be immediately effective, with “effectiveness” often narrowly, if not wholly, defined by the results of student standardized test scores. Research Design We address the question by offering an appreciative exploration of core practices approaches to teacher education. We argue (a) that philosophers of education have much to learn by engaging these approaches, and that (b) practitioners and advocates of core practices can deepen their work through a critical appreciation of philosophy of education. Conclusions/Recommendations Though philosophy appears marginalized by core practices approaches to teaching and teacher education, we suggest that as core practices gain traction, philosophers of education will find new opportunities to engage with teaching and teacher education. Though much mitigates against this type of work, most notably the pressures related to effectiveness and institutional habits that still often separate methods and foundations courses, we argue that such work is indispensable in rendering teaching, and teacher education, both effective and responsible.

Abstract:

Objective: India is considered to be a diabetic capital as many Indians are diabetic. The common treatment for diabetes is medication. The purpose of this study is to bring out the other remedial measures for diabetic treatment and to create awareness among the people about the alternative measures. This study is about the effect of balancing exercise and tai chi exercises for early diabetic. It is, therefore, possible that an individual can experience a noticeable decreased in blood glucose following a balancing exercise and modified tai chi program. This study is to find out the effect of balancing exercise and tai chi program and to compare the effectiveness.Methods: Once the study is approved by the institutional review board, 50 samples from 65 volunteers with Type 2 diabetes between the age group of 25–35 years were selected from the ACS Medical College and Hospitals based on the inclusion criteria. After getting the consent, the samples were equally divided into two groups; Group A: Balancing exercise and Group B: Tai chi exercise. Both groups received intervention for 8 weeks 6 days/ week 2 sessions/day. Pre- and post-test was done using the outcome measures of blood glucose levels (glucometer), body mass index, and waist circumference (inch tape).Result: On comparing the mean values of waist circumference and blood glucose level between Group A and B, both the groups showed significant reduction in the post-test values. However, Group B tai chi for diabetes shows the mean (34.4) which is effective than the Group A (38.5) for waist circumference (in inches) and also Group B (156.70) is effective than the Group A (184.10) for blood glucose level (mg/dL) at p≤0.05.Conclusion: The study concluded that the balancing exercise and tai chi exercise are effective in the reduction of blood glucose level and waist circumference. However, tai chi is more effective than the balancing exercise.

Abstract:

Energy efficiency is still a challenging issue in wireless sensor networks (WSNs). Balancing nodes’ activities and duty cycling are efficient ways that could enhance WSN’s performances. In this paper the authors introduce a new asynchronous power saving mechanism that provides an adaptive duty cycle and a minimum overhead to achieve load balancing and energy saving. This mechanism relies on two basic functions: an asynchronous duty cycling for activity balancing and a lightweight geographic routing. Extensive simulations showed the effectiveness of the proposed approach in terms of residual energy, energy consumption balancing and packet delivery ratio.

Abstract:

Recent EU legislation enforces the integration of European balancing markets, with harmonized products and international platforms for the procurement and activation of reserves; nonetheless, different power balancing strategies remain. The Netherlands and Belgium encourage market participants to support balancing the control block by publishing real-time information. This article refers to such concepts as smart balancing, and a market simulation tool was developed to assess the relevant market parameters for effective smart balancing. This shall contribute to the true integration of real-time balancing energy markets. The scope of the assessment of relevant market parameters was Germany, and the results showed that a pricing scheme had less impact on the results, as currently is understood by European TSOs and regulators. Moreover, the accuracy and frequency of real-time publication indicate the effectiveness of smart balancing and the associated reduction of the activation of balancing energy and associated costs. Consequently, this article proposed a road map for Germany to introduce an adapted smart balancing approach, starting with a simple traffic light.

Abstract:

The aim of this study is to study the effectiveness of using coloured blocks in teaching the concept of balancing chemical equation in chemistry. It is expected that students will improve their understanding in this concept and students interest in chemistry. This study examined how by using coloured blocks will help students understand the concept of balancing chemical equation which is an important concept to master in Form 4 Chemistry. Using pre and post-test control group design, the study involved a comparison between a control group (n=20) which were taught using the conventional chalk and talk method to balance chemical equation while the treatment group (n=20) were taught to balance chemical equations using coloured blocks. After pre-test, there was a significant difference between control and treatment group on their post-test scores with effect size of 1.31. Students who had used coloured blocks to balance chemical equations showed significant development in their post-test compared to the students who were taught using the conventional method. Students also showed high interest in chemistry upon using coloured blocks in teaching the concept of balancing chemical equation. The research results recommended the use of coloured blocks as a potential tool to teach the concept of balancing chemical equations..

This paper presents the design of a passive two leg orthosis to gravity balance human legs for use by subjects with both leg impairment. This design combines the use of auxiliary parallelograms to locate the center of mass along with springs to achieve balancing of each leg. The gravity balancing for all motions of the leg and pelvis is achieved by assuming the center of mass of the pelvis to be located on the line joining the two hip joints. A method for deriving the effectiveness of the gravity balancing due to practical limitations is also outlined. We illustrate the gravity balancing feature of the orthosis and examine the assumptions through computer simulations.

Abstract:

Abstract The simulation model of the computational load balancing in a server complex using a balancing server is proposed. The server load balancing model was developed using MATLAB/Simulink/SimEvents/Stateflow tools. The SimEvents based model makes it possible to simulate the server complex as a queuing system and to take into account the sporadic occurrence of requests. The Stateflow based event-driven model simulates the system with a variable time delay in data transmission channels and simulates state transitions for servers. This discrete-event simulation model allows evaluating the possibility of rational use of computational resources and reducing the time of service. In addition, the model allows to investigate the effectiveness of load balancing systems at the stage of their development.

According to the characteristics of aircraft subassembly, an optimal method for task balancing under resource constraints is presented. Firstly, the judgment indexes are abstracted to represent the running state of the assembling task, and mathematic model of assembling task balancing was established by available resources. Considering feature of aircraft subassembly, a fitness function is proposed based on two-stage priority targets, which are specific to task sequence and resource allocation respectively. Afterwards, Genetic-Tabu hybrid operations are executed to get the optimal solution. Finally, the effectiveness of this method is verified by applying to assembly task balancing of an outer flank.

Abstract:

This paper describes a framework that can be used to evaluate the environmental risks and benefits associated with biofuel production. It uses the example of biodiesel produced from Argentinean soy to show how such a framework can be used to conceptualize trade-offs between different environmental, social and economic impacts of biofuel production. Results showing the greenhouse-gas savings and overall life-cycle impact of different ‘soy-biodiesel’ production methods are presented. These impacts and the significance of uncertainty in overall assessments of key parameters, such as greenhouse-gas savings, are discussed. It is shown that, even where sufficient knowledge exists to be able to quantify these impacts, the sustainability of supply of a particular biofuel is inextricably linked to values and ethical judgements. However, tailoring certification efforts to the issues that are most likely to make a significant difference to the overall sustainability could improve the effectiveness of certification efforts. The potential for a framework to guide and focus certification efforts is discussed and future research and policy priorities suggested.

Abstract:

Aposematic signals are often characterized by high conspicuousness. Larger and brighter signals reinforce avoidance learning, distinguish defended from palatable prey and are more easily memorized by predators. Conspicuous signalling, however, has costs: encounter rates with naive, specialized or nutritionally stressed predators are likely to increase. It has been suggested that intermediate levels of aposematic conspicuousness can evolve to balance deterrence and detectability, especially for moderately defended species. The effectiveness of such signals, however, has not yet been experimentally tested under field conditions. We used dough caterpillar-like baits to test whether reduced levels of aposematic conspicuousness can have survival benefits when predated by wild birds in natural conditions. Our results suggest that, when controlling for the number and intensity of internal contrast boundaries (stripes), a reduced-conspicuousness aposematic pattern can have a survival advantage over more conspicuous signals, as well as cryptic colours. Furthermore, we find a survival benefit from the addition of internal contrast for both high and low levels of conspicuousness. This adds ecological validity to evolutionary models of aposematic saliency and the evolution of honest signalling.

Full text

Abstract:

Aiming at improving assembly line efficiency and flexibility, a balancing method of parallel U-shaped assembly line system is proposed. Based on the improved product priority diagram, the bidirectional priority value formula is obtained. Then, assembly lines are partitioned into z-q partitions and workstations are defined. After that, the mathematical model of the parallel U-shaped assembly line balancing problem is established. A heuristic algorithm based on bidirectional priority values is used to solve explanatory examples and test examples. It can be seen from the results and the effect indicators of the assembly line balancing problem that the heuristic algorithm is suitable for large balancing problems. The proposed method has higher calculation accuracy and shorter calculation time. The balancing effect of the parallel U-shaped assembly line is better than that of single U-shaped assembly line, which verifies the superiority of the parallel U-type assembly line and effectiveness of the proposed method. It provides a theoretical and practical reference for parallel U-type assembly line balancing problem.

Abstract:

In this paper, we propose an automatic load-balanced partitioning strategy for parallel multilevel fast multipole algorithm(MLFMA) based on distributed-memory architectures to solve the large scale electromagnetic scattering problems. We focus on the automatic load-balancing partitioning strategy because that our original scheme requires that users input the transition level, which is usually determined on the users’ experience and sometimes lead to a bad load-balancing partition. By introducing the automatic load-balancing algorithm to our pervious partitioning technique, our implementation can automatically achieve the best load-balancing and consequently attain better parallel efficiency. To present the effectiveness of the new strategy, we analyze results of the previous implementation according to different inputs of transition level and compare them with the result of implementation using the new algorithm.

Network resources limitations and ensuring quality of service requirements lead to an important need for load balancing between SDN switches. The purpose of work  research and analysis of load balancing processes in SDN based on genetic algorithm. To confirm the effectiveness and correctness of the genetic algorithm in SDN, the software for modeling the load balancing processes has been developed. The simulation results confirmed the efficiency of the genetic algorithm in SDN for balancing and redistributing network traffic in order to ensure the required quality of service and reduce network congestion.

Abstract:

In industries like the aircraft gas turbine, trans-critical or super-critical operating speeds are quite common, and rotating machinery must be mass produced with very demanding precision in balance effectiveness, generally without recourse to high-speed balance procedures. A procedure has been developed which permits high-speed multi-plane (i.e., three or more plane) balance correction to be made on rotors in simple conventional low-speed balance machines (Patent Applied For). The procedure accomplishes most of the benefits of actual high-speed or modal or true multi-plane balancing by utilizing other known or available data on the particular rotor’s generic dynamic behavior (i.e., its natural or critical mode shapes) and data on the particular rotor’s generic design and manufacture (i.e., its perceived generic patterns of unbalance distribution). For (N) balance planes, the procedure involves the specification of a Balancing Rule wherein a sequence of (J) low speed balance steps is specified (where J equals the integer part of [(N + 7)/2]). At each of these steps, some fraction (called a Balancing Factor) of the measured two plane unbalance vectors is applied to one or two of the other balance correction planes, before final correction is made on the last two correction planes themselves. A procedure is derived to predetermine those (I) Balance Factors (where I equals [N-2]). The procedure involves an iterative sequence for computing the optimized Balance Factors, with convergence driven by the Newton Raphson procedure, and requires the specification of (I) pairs of generic unbalance distributions and natural mode shapes. The analytically derived Balancing Factors are designed to null the vibration response of the rotor excited by each of the specified generic unbalance distributions at the critical speed associated with the specified mode shape with which the generic unbalance distribution is paired.

Abstract:

Active balancing actuators are essential components of intelligent machine tool spindles to automatically reduce the unbalance vibration and promote machining accuracy and efficiency. In this study, a novel electromagnetic-ring actuator is introduced, which can be integrated into the hollow rotor of the spindle and compensate the initial mass imbalance through step rotation of two counterweight discs driven by the magnetic field. The working principle of the actuator is described in detail and its performance is analyzed, including balancing ability, balancing accuracy and self-lock capacity. To control the normal operation of the actuator, a phase detection and control program was developed. Finally, to verify the effectiveness of the novel actuator, function experiments and active balancing experiments were carried out. The experimental results show that the novel actuator could reduce the unbalance vibration of the machine tool spindle by 87.5% at 3600 rpm.

Abstract:

As data mining develops and expands to new application areas, feature selection also reveals various aspects to be considered. This paper underlines two aspects that seem to categorize the large body of available feature selection algorithms: the effectiveness and the representation level. The effectiveness deals with selecting the minimum set of variables that maximize the accuracy of a classifier and the representation level concerns discovering how relevant the variables are for the domain of interest. For balancing the above aspects, the paper proposes an evolutionary framework for feature selection that expresses a hybrid method, organized in layers, each of them exploits a specific model of search strategy. Extensive experiments on gene selection from DNA-microarray datasets are presented and discussed. Results indicate that the framework compares well with different hybrid methods proposed in literature as it has the capability of finding well suited subsets of informative features while improving classification accuracy.

Abstract:

AbstractSince its modern inception in the 1960s, international environmental law (IEL) has faced three main challenges: (i) justifying the need for an international regulation of environmental issues (legitimacy); (ii) finding mechanisms to ensure compliance with IEL (effectiveness); and (iii) distributing equitably the benefits and burden of environmental protection (fairness). While it is nowadays possible to say that the legitimacy of IEL is no longer in question, the need to respond to challenges (ii) and (iii) has never been more pressing. This is particularly the case in the context of the redesign of the climate change regime (CCR), as the responses to (ii) and (iii) may conflict with each other. Industrialized countries who historically contributed the most to the artificial increase in greenhouse gases (GHGs) in the atmosphere have been matched, and even surpassed, in their level of GHG emissions by countries such as China, India, or Brazil, who are now being pressed to undertake real emissions-reduction commitments. Historically, however, none of these latter benefited from the emission laxity characterizing the nineteenth century and most of the twentieth century to further their development. While imposing specific emissions-reduction commitments on them would seem unfair, such commitments are nevertheless critical for the effectiveness of the regime both directly and indirectly (as without such commitments, industrialized countries may be reluctant to join or uphold a regime). The purpose of this article is to spell out in an orderly analytical manner the types of issue that must be addressed in seeking a balanced solution. This type of analysis can be conducted from several perspectives. The most directly relevant disciplines to deal with fairness considerations are admittedly ethics and political philosophy, and there is indeed a growing literature on climate fairness. Although this literature is briefly surveyed, the article focuses on the fairness dimensions of the existing legal arrangements or those currently being negotiated. There is a considerable gap between the theoretical approaches to climate fairness and the manner in which considerations of fairness operate in practice. This gap is mainly due to the need to account for political considerations or, in other terms, to balance fairness with political effectiveness. When such considerations are taken into account, the picture that emerges is quite different. The CCR is not built upon a single approach to fairness. Rather, fairness considerations are integrated through a patchwork of criteria used to distribute different objects (burden of emission reductions, emission rights, contribution to financial and technological assistance, and access to such assistance) among different actors situated at different levels.

Abstract:

Motorized spindles widely used for high-speed precision machine tools are very sensitive to the mass unbalance of rotors; thus, their balancing problem is always a research hotspot. Although many significant studies were done regarding the theory and application of various rotor balancing technologies for motorized spindles, the particularity of motorized spindles is not carefully considered in the existing balancing approaches. When the rotor unbalance of a motorized spindle occurs in operation, it is subject to both the mass unbalance-induced inertia force and air gap unbalance-induced electromagnetic force, which is an important feature that distinguishes the motorized spindle from a mechanical spindle. This paper describes an investigation into the corrected adaptive balancing approach of a motorized spindle by newly introducing a coefficient representing the removing effect of the air gap unbalance of the motor on the balancing capacity into the balancing formula. The determination of the newly defined coefficient refers to the calculation of electromagnetic force caused by the dynamic air gap eccentricity of motor; thus, much attention is paid to the analytical derivation of the unbalanced magnetic pull (UMP). Finally, a motorized spindle with an electromagnetic ring balancer was developed; then, the balancing tests and vibration signal analysis were done to validate the effectiveness of the newly proposed balancing approach in residual vibration reduction. It can be seen from the test results under different cases that the proposed balancing approach is effective.

Abstract:

With the development of high-speed rotating machinery, the unbalance vibration feature of each rotor system has a greater influence on the work efficiency, bearing life, operational time, etc. Therefore, an active balancing system is necessary to automatically reduce the unbalance vibration in the process of rotor operation. This study introduced a novel liquid transfer active balancing system for the hollow rotors, and compensation mass was performed by balance liquid transmission between two pairs of contra-positioned chambers. The performance of this new balance actuator was analyzed, including balancing velocity, balancing accuracy, and the effect on rotor dynamics. A monitoring and control program was constructed to control the balance actuator. Two extraction methods of synchronic vibration were introduced and quantitatively compared through simulation. A control program was developed and the control accuracy was within 1 ms. Furthermore, the effectiveness of the new balancing system was verified through active balance experiments and the maximum speed was 15,600 rpm. The results indicate that the balancing system could effectively decrease the unbalance vibration of the rotor system within 10 s, and the amount of decrease was more than 80%.
