Improved data expansion method used in damage detection method | In this paper, a damage detection method based on modal parameters, which deals with incomplete measurement, is presented. Intact and damaged structures are modeled using the finite-element method. Damage in structure is assumed as a reduction in elastic modulus. This study utilizes an approximate stiffness matrix of damaged structure to improve the data expansion methods, which is used to complete the incomplete modal parameters of damaged structures. Verification of proposed method is done using a 2D truss and a 2D frame. This method is able to expand the measured data and to solve the sensitivity equation, which depends on complete mode shapes and frequencies of intact and damaged structure, and to detect the damage in the presence of noises, such as measurement and modeling errors. Results show that damage detection using improved data expansion is more accurate and reliable than damage detection using common data expansion. | Large-scale construction projects frequently appear which make people pay more attention to the performance evaluation.This paper established the large-scale construction projects'performance evaluation index system and carried out comprehensive evaluation of the performance with a combined model of fuzzy theory and the matter-element theory.The analytic hierarchy process and the membership function were used to determine the weights of indicator elements and the membership matter-element.Finally,the study used the performance indicator system in construction phase for a large-scale project as an example to verify the fuzzy matter-element correctness,rationality and feasibility. | eng_Latn | 2,805 |
Field Application of a Robotic System on Cable Stays of Incheon Bridge for Snow Removal | Recently, an increase in the number of construction of long span bridges like a cable-stayed bridge has necessitated the development of technologies for long-term maintenance works and safety of vehicles using such bridges. A lot of researches on application of cutting-edge IT technologies and robotics in the civil engineering field have been conducted for better operation and maintenance of a bridge (Integrated Construction Technology). The cable stays supported by two inverse-Y type pylons of Incheon Bridge are located at the center of the bridge, which results in a potential risk of snow drifts and ice on the cables falling onto the road, threatening the safety of driving vehicles.

A Model of Grid Branches Segmentation Differentiated Planning Considering Risk | To reduce the outage risk resulting from grid branches, the model of branches segmentation differentiated planning is proposed considering the grid transmission branches crossing multiple different meteorological regions in this paper. Firstly, the failure probability model of transmission branches based on Pearson III is presented from the historical ice thicknesses. Then, considering the constraints of load losses and planning costs, the objective function of the model is to minimize the risk loss costs and the differentiated enhancement costs. The model is solved by Monte Carlo-random sampling algorithm, from which the segmentation differentiated enhancement standards is obtained. Through the IEEE-18 bus system, the proposed model is proven to be effective and suitable for branches differentiated planning across different meteorological regions, which can improve anti-disaster capacity. | Abstract How do people select their movement paths in a complex building? How do evacuees find their way to the exits? How do customers orient themselves within a shopping center? The paper presents the wayfinding problem in a mathermatical setting, providing numerous models of wayfinding behaviour, ranging from the simplest random walk models to more complex shortest path rules. The models are analyzed numerically to illustrate their implications on the performance of the wayfinding process. Such models are of great importance when one studies how persons evacuate from a building.

Position and orientation best-fitting based on deterministic theory during large scale assembly | Abstract Position and orientation (P&O) of the large-size component are very important geometrical quantities, which are observed by digital metrology techniques and controlled by fixed or flexible fixtures during assembly. The observed P&O values are usually calculated using measured coordinates of several points on the surface of the large-size component, based on the precondition that the relative position of those points is unchanged. In this paper, a novel P&O best-fitting algorithm is proposed. The related work firstly discussed the influences of the structural deformation of the large-size component on the P&O observation during assembly, and then introduced a deterministic theory for considering the influences. Based on the deterministic theory, the novel best-fitting algorithm which includes three steps was detailed. Finally, based on a wing-fuselage alignment case, the proposed algorithm is verified to be more accurate than the traditional methods, and the computing process is verging and stable. | We consider a general queueing network with multi-server stations.

The developed method has also been illustrated numerically to test the efficiency of the method where it is observed that the proposed method yields a better result. | Publisher Summary This chapter reviews that there is a gap between formal decision theory and practical societal decisions, especially those on an aggregated level and/or with general political implications. There are important, qualitative observations from the formal theory that serves as valuable guidelines for practical decisions, often in the form that they provide warnings for pitfalls. One such observation is the inability of the intuitive mind to pay simultaneous attention to all the various aspects of a multidimensional problem. The chapter discusses that Suppes' approach is very broad, being concerned only with distributions of gross amounts of money to the broad areas of scientific research. It also proposes to reduce the use of intuitive judgments to one-dimensional situations—that is, to the ranking of major research areas according to one specific criterion. | eng_Latn | 2,810 |

An Approach to Synthesis of Multivariable PID Controllers for a Class of Nonlinear Systems and Its Application | Abstract This paper considers a synthesis of multivariable proportional-integral-derivative (PID) controllers for a class of nonlinear systems. First, mathematical models of plant with a class of nonlinearities and PID controller with saturation nonlinearity are given. Then, the closed-loop system is described by a descriptor form. Secondly, an analysis condition for descriptor systems with sector-bounded nonlinearity is introduced. Based upon the condition and a representation for the nonlinearities in the control system, the synthesis problem is formulated as a bilinear matrix inequality one. The matrix inequality problem is solved by an iterative linear matrix inequality algorithm to synthesize a PID controller so as to minimize the L 2 -gain and expand the region of sector. Finally, to verify the effectiveness, the synthesis method is applied to the synthesis of PID controller for a ball-on-wheel system with input saturation. | The key factor for improving the efficiency of assembly sequence planning is to reduce the number of components involved in the search or generation of assembly sequences.

Designing Difficult Office Space Allocation Problem Instances with Mathematical Programming | Office space allocation (OSA) refers to the assignment of room space to a set of entities (people, machines, roles, etc.), with the goal of optimising the space utilisation while satisfying a set of additional constraints. In this paper, a mathematical programming approach is developed to model and generate test instances for this difficult and important combinatorial optimisation problem. Systematic experimentation is then carried out to study the difficulty of the generated test instances when the parameters for adjusting space misuse (overuse and underuse) and constraint violations are subject to variation. The results show that the difficulty of solving OSA problem instances can be greatly affected by the value of these parameters. | A statistical model is established to estimate the effects of the geometric and nongeometric errors on the quality of the operation for various operating speeds.

As a method of procuring buildings, the design and build approach accounts for an increasing proportion of building construction output in the United Kingdom. This paper reports a survey of contractors, designers, and building clients regarding design and build issues. These issues include the circumstances in which the approach would be suitable, the project organizations commonly employed on design and build projects, the difficulties commonly encountered by practitioners, and the attitudes of the construction professionals to the procurement route. The main findings of the research are as follows: (1) The use of design and build is on the increase with many clients perceiving it as providing better value for money and giving rise to less disputes than other procurement methods; (2) the approach can be used satisfactorily with most sizes of projects provided the client is experienced; (3) although more and more of the construction professionals accept the approach, there is still considerable resistance... | Construction clients are increasingly calling for bids that require contractors to submit both bid price and highlight sustainability attributes. Contractors are faced with the problem of deciding which combination of bid price and sustainability attributes to submit. An important consideration is the cost of sustainability attributes to the client. This varies between contracts and types of projects. This paper proposes the use of a sustainability unit value which the client can use as a basis for determining the contractor's total combined bid. This kind of procurement method is traditionally known as the A+B method. To illustrate the mechanism of price-sustainability attribute bi-parameter procurement, a total combined ISO-map is developed. The contractor's price-sustainability performance curve is then incorporated into the map to determine the contractor's optimal bid parameters: tender price and sustainability performance. A mathematical optimisation bid model is developed for calculating the optimal bid parameters. | Berzelius failed to make use of Faraday's electrochemical laws in his laborious determination of equivalent weights. | eng_Latn | 2,828 |

In this paper, a quantitative framework of analysis for supporting decision making in project risk response planning is developed and studied. The design structure matrix representation is used to capture risk interactions and build a risk propagation model for predicting the global mitigation effects of risk response actions. For exemplification, a genetic algorithm is used as a tool for choosing response actions and allocating budget reserves. An application to a real transportation construction project is also presented. Comparison with a sequential forward selection greedy algorithm shows the superiority of the genetic algorithm search for optimal solutions, and its flexibility for balancing mitigation effects and required budget. | We report enhancement of the mechanical stability of graphene through a one-step method to disperse gold nanoparticles on the pristine graphene without any added agent. | eng_Latn | 2,829 |
The design process has a significant impact on the performance and profitability of a housing project. Therefore, decisions made during the design process should take into consideration knowledge and experience from other processes in previously accomplished projects, specifically from the production phase. How to capture and use production experience in housing has not gained enough interest, possibly leading to sub-optimal improvements during the construction process. This motivates research on how onsite production experience from similar previous projects can be captured and used to improve constructability without risking customer values. Based on the concept of constructability, ‘design for manufacturing and assembly’ and the theory of waste, the method ‘design for construction’ (DFC) has been developed. The four-step model complements the conventional construction process, and consists of the following steps: (1) specify customer values and similar previous projects; (2) identify onsite waste and cost drivers in previous projects; (3) develop criteria to evaluate constructability; and (4) evaluate constructability of the design. The DFC method is exemplified and tested through a case study, in which it was shown that the method facilitated identification of all problems that were considered in the investigated project. The method also highlighted other project obstacles that potentially could have been solved to improve constructability. | The purpose of this study is to develop methods in the design of roundabouts that can be used in early conceptual phases of infrastructural projects to avoid erroneous solutions propagating downstr ... | We prove that groups acting geometrically on delta-quasiconvex spaces contain no essential Baumslag-Solitar quotients as subgroups.

Large-scale urban construction comprised of multiple construction projects of different types poses a challenge to progress management. While the progress of a construction project can be measured as the percentage of a facility’s physical completion, this standard is less reliable an indicator in gauging the progress of an urban construction project, as the function of urban facilities determines their role in the completion of an urban system. This paper suggests a new measurement framework consisting of five hierarchically structured models in order to better assess construction progress for large-scale urban projects. To test the validity of the proposed framework, it has been applied to a real-life urban development project carried out in Sejong Special Self-Governing City, South Korea. The weight set on functional importance was quantified according to the analytic hierarchy process method. This study also conducted a survey of 23 practitioners who managed the case project. The contribution of this research is to propose a framework that redefines the progress of urban construction projects by focusing on functional importance in urban systems and formulating a qualitative method of calculating progress for urban construction projects. Such achievements are expected to provide useful information to project managers concerning the extent to which an urban construction project has progressed and the extent to which the progress of an individual project affects the progress of an urban project as a whole. | Operating profit is one of the most important measures in financial statements to evaluate a organizational performance. In the construction industry, however, the profit has a possibility to be misestimated as a loss and can be included in Unbilled Accounts Receivable (UAR) and shown as a profit; this is due to the uncertainty of predicting a total construction cost and project progress on which the calculation of profit is based. UAR results from the different perceptions regarding project progress between clients and contractors and can include costs related to loss that cannot be acknowledged as a progress. Therefore, UAR can be a significant clue to understanding estimation errors of a contractor’s financial performance data. This study investigated the possibility of estimation error of contractors’ operating profit by analyzing the relationship between UAR and other relevant financial performance measures. The accounting data of 41 Korean major contractors was collected and analyzed based on the correlation analysis. The results of this study implies that the profit of construction companies has the possibility to contain estimation errors, causing a significant variance in the process of adjusting the evaluation errors at the end of projects, which can cause unexpected losses to investors. In addition, this study found that the UAR containing estimation errors could be different depending on market in which contractors operate; therefore, when dealing with contractors’ financial performance data, it is necessary to discern whether their profit data contains distortion and, in the case that errors are included, appropriate data preprocessing should be conducted for more reliable and sustainable construction investment and project management. | Berzelius failed to make use of Faraday's electrochemical laws in his laborious determination of equivalent weights. | eng_Latn | 2,831 |

Development of a Conceptual Model to Support ERP System Selection in Developing Countries | Enterprise Resource Planning (ERP) systems have been heavily adopted in developed countries in the past decade and most studies on ERP adoption and selection focuses on these countries. With the emerging trend of ERP adoption in developing countries, the crucial question is: How to select an adequate ERP system. Of course this is not a new issue and already discussed in the developed countries, but many of the available studies are highly focused on this setting. Developing countries can actually adopt the available selection models but the suitability of the models has to be approved in the context of these countries. This proposal, therefore, intends to indicate the methodology to be followed in analyzing the suitability of the existing selection models in order to come up with a prototype of a suitable ERP system selection model for Ethiopia’s context. | SUMMARY The increasing complexity of modem buildings and the client's desire for swift occupation has meant the expeditious completion of the design phase of a project has become ever more important. An effective and workable design programme is essential to achieve this. Traditionally, building design work has been planned in a perfunctory manner, often in the belief that this creative and iterative process cannot be analyzed and planned in detail. This situation has been perpetuated by a lack of understanding of design information flow and dependency, and the availability of suitable planning techniques. This paper describes a data flow model of the building design process that is subsequently analyzed in a design structure matrix. The synthesis of these two techniques produces a powerful but easily understood tool to assist in the planning and management of complex, multi-disciplinary building design problems. | eng_Latn | 2,857 |

The measurement of complexity in surgical pathology. | The quantitation of effort both within and among surgical pathology laboratories is data which is being increasingly sought by physician managers, hospital administrators and managed care organizations. Simple measurement of case numbers fails to adequately represent the work of a laboratory. The complexity of the cases reviewed is likely to explain a significant portion of the variance in the time required to bring a case to final diagnosis. Measures which adequately reflect complexity in surgical pathology cases have not been developed. We have studied a variety of extractable report features and correlated these with the time required for case sign-out. Numbers of slides reviewed and total lines of factual data provided were strong correlates of the time required to complete case review, report construction and verification. Such data suggests that models can be constructed based on data that can be gleaned from case reports and records which will relate such data to actual work time. | Different systems act as one of the most promising forms of integration in the urban planning structure.

Modeling of Mass Transfer in Nonideal Multicomponent Mixture with Maxwell-Stefan Approach | Abstract The Intalox metal tower packing was used to simulate an industrial relevant extractive distillation column for purifying azeotropic multicomponent mixture. In order to explain the inconsistencies in the modeling of transfer process in nonideal multicomponent distillation column, a method was developed with equilibrium stage models (EQ) and non-equilibrium model (NEQ) incorporated with Maxwell-Stefan diffusion equations in the framework of AspenONE (r) simulator. Dortmund Modified UNIFAC (UNIFAC-DMD) thermodynamic model was employed to estimate activity coefficients. In addition, to understand the reason for the diffusion against driving force and the different results by EQ and NEQ models, explicit investigations were made on diffusion coefficients, component Murphree efficiency and mass transfer coefficients.

PREDICTING NATURAL VENTILATION IN A TWO-ZONE BUILDING DRIVEN BY COMBINED FORCES | Natural ventilation relies on less controllable natural forces so that it needs more artificial control, and thus its prediction, design and analysis become more important. This paper presents both theoretical and numerical simulations for predicting the natural ventilation flow in a two-zone building with multiple openings which is subjected to the combined natural forces. To our knowledge, this is the first analytical solutions obtained so far for a building with more than one zones and in each zone with possibly more than 2 openings. The analytical solution offers a possibility for validating a multi-zone airflow program. A computer program MIX is employed to conduct the numerical simulation. Good agreement is achieved. Different airflow modes are identified and some design recommendations are also provided. | Different systems act as one of the most promising forms of integration in the urban planning structure. In the process of formation of plans for social and economic development of major cities more often, there is a situation, when the improvement of resources efficiency needs not just a concentration of effort, but also some new and innovative forms of building production organization. It is proposed to establish in Odessa the "Corporate Scientific and Technical Complex of urban planning energy renovation" as an innovative organizational structure which practically uses the accumulated scientific and technical potential for the reconstruction of historic buildings in Odessa in 1820–920 using energy efficiency standards.

Understanding the basic principles of programme evaluation. | In public health, it is important to evaluate programmes (series of activities to achieve specific objectives in specific target groups) in research, surveillance, services, education and policy; in other words, to determine as systematically and objectively as possible the relevance, effectiveness and impact of programmes with respect to their objectives.1 It has been suggested that evaluation should be a built-in component of public health programmes.2 ::: ::: The basic principles of evaluation are information and expectation. Information can be obtained using the method of surveillance.1 3 4 Important steps in information include deciding on the list of indicators to be monitored and making sure that pertinent information is available. Even … | This paper describes the rule structure used to select the appropriate sequence of operations to produce various types of holes in 2 1/2D prismatic components manufactured on machining centres. Operation selection is based on forward chained rules coded in Prolog. A different rule priority sequence is applicable depending on the rule fired last. This solves the conflict resolution problem and ensures reasonably fast execution. Rule conditions perform feature extraction, feature size checks, operation suitability checks, tool suitability checks and processing status checks. Actions perform the processing operations and update the model through feature processing tags. The knowledge base implemented for hole-making was not obtained from a practical industrial environment. Nevertheless it does produce sensible plans and it is relatively easy to modify. | eng_Latn | 2,887 |
A Simulation Study of Data Collection Based on Vehicle Infrastructure Cooperation | Recently, Intelligent Vehicle Infrastructure Cooperation System (IVICS) was proposed and became a focused area of frontier research. Different from traditional ITS technology, IVICS enables a safer, smarter and greener traffic environment since full-scale data of traffic network can be easily obtained through vehicle-vehicle (V2V) and vehicle-infrastructure (V2I) communications. In this paper, we first investigate the main characteristics of IVICS and then study data collection based on vehicle infrastructure cooperation, which plays an extremely important role in various kinds of traffic applications. A secondary development using Visual C#.NET is applied to current commercial traffic simulator VISSIM 4.30 through its COM interface. Virtual Road-Side Units (RSUs) and On-Board Equipments (OBEs) which realize V2V and V2I Communications are embedded in the simulator. Finally, a prototype system is developed to demonstrate the practicality. | Abstract Although they create considerable economic benefits, industrial parks emit tremendous amounts of pollution and consume significant environmental resources. This investigation examines problems associated with managing an industrial park. It begins by defining an industrial park system and its sustainability. Next, using systems thinking, managing for results, driving-force-pressure-state-impact-response, and system dynamics, we develop a management framework and an indicator system. A framework with triple decision layers is established to link the management of an industrial park with its manufactories. Based on this framework, proposed indicators and their driving force–pressure–state–impact–response relationships are integrated into an optimization model to maximize sustainability, so that sustainability of an industrial park is assessed as total quantity management is performed. A prototype of a total quantity and sustainability management strategy for industrial parks is developed, based on ... | kor_Hang | 2,888 |
Regression Test Case Prioritization Technique Using Genetic Algorithm | Regression testing is a maintenance action in which it ensures validity of changed software. Regression testing takes much time to execute the entire test suite and this activity is very costly. In this paper we present a technique which is based on Genetic algorithms (GA) for test case prioritization. Genetic algorithm is a generative algorithm based on natural evolution which generate solutions to optimization problem. In this paper, a new Genetic algorithm is used for regression testing that will prioritize test cases using statement coverage technique. The Algorithm finds fitness function using statement coverage. The results shows the efficiency of algorithms with the help of Average Percentage of Statement Coverage (APSC) metric. This prioritization technique shows optimum results to prioritize the test case. Genetic Algorithm is used to produce the population and it finds the optimal sequence order of test case in regression testing. | Large-scale construction projects frequently appear which make people pay more attention to the performance evaluation.This paper established the large-scale construction projects'performance evaluation index system and carried out comprehensive evaluation of the performance with a combined model of fuzzy theory and the matter-element theory.The analytic hierarchy process and the membership function were used to determine the weights of indicator elements and the membership matter-element.Finally,the study used the performance indicator system in construction phase for a large-scale project as an example to verify the fuzzy matter-element correctness,rationality and feasibility. | kor_Hang | 2,889 |
2 Equitable aggregations and multiple criteria analysis | Abstract In the past decade, increasing interest in equity issues resulted in new methodologies in the area of operations research. This paper deals with the concept of equitably efficient solutions to multiple criteria optimization problems. Multiple criteria optimization usually starts with an assumption that the criteria are incomparable. However, many applications arise from situations which present equitable criteria. Moreover, some aggregations of criteria are often applied to select efficient solutions in multiple criteria analysis. The latter enforces comparability of criteria (possibly rescaled). This paper presents aggregations which can be used to derive equitably efficient solutions to both linear and nonlinear multiple optimization problems. An example with equitable solutions to a capital budgeting problem is analyzed in detail. An equitable form of the reference point method is introduced and analyzed. | Aimed at the problem of the configuration program of road maintenance machinery index difficult to quantify, by using the method of fuzzy comprehensive in highway maintenance machinery configuration evaluation, depicted some fuzzy phenomena with subjective qualitative description , closely integrated quantitative analysis and subjective qualitative description.

Evaluation of the Midwest Guardrail System stiffness transition with curb | ABSTRACTA W-beam to thrie beam stiffness transition with a 102-mm (4-in.) tall concrete curb was developed to connect 787-mm (31-in.) tall W-beam guardrail, commonly known as the Midwest Guardrail System (MGS), to a previously developed thrie beam approach guardrail transition system. This upstream stiffness transition was configured with standard steel posts that are commonly used by several state departments of transportation. The toe of a 102-mm (4-in.) tall sloped concrete curb was placed flush with the backside face of the guardrail and extended the length of the transition region. Three full-scale crash tests were conducted according to the Test Level 3 (TL-3) safety standards provided in AASHTO's Manual for Assessing Safety Hardware (MASH). The first test, MASH Test No. 3-20, was deemed a failure due to guardrail rupture. The stiffness transition was modified to include an additional nested W-beam rail segment upstream from the W-beam to thrie beam transition element. MASH Test No. 3-20 was repeate... | Abstract The present paper deals with optimizing optimal operation interaction for GCUM 1st and 2nd lines by proposing a methodology based on field survey of travel time, actual headway, passenger waiting time, alighting and boarding passengers to determine the actual passenger density on platform, passenger density in train and target headway, consequently the ideal operation and the corresponding operational costs savers.

Energy-Efficient Dimensioning with Traffic Engineering for Municipal Mesh Access Networks | We target energy efficiency of municipal access networks. A municipal access network typically provides coverage for city-wide area, and is characterized by diverse and dynamic traffic profiles. Most existing approaches to energy savings adapt network state to traffic variation. However, these approaches fail to capture the potential of energy savings by exploiting the traffic that has already existed in the network. We study network dimensioning for municipal mesh access networks to save energy by rearranging existing traffic and adjusting link rate. The problem of energy-efficient network dimensioning is formulated using mixed integer linear programming. We also propose an efficient heuristic algorithm that consists of both traffic engineering and link-rate adaptation. Numerical experimental results show that our scheme is more effective than link-rate adaptation in saving energy, and achieves a good balance between energy efficiency and resource efficiency. | Aimed at the problem of the configuration program of road maintenance machinery index difficult to quantify, by using the method of fuzzy comprehensive in highway maintenance machinery configuration evaluation, depicted some fuzzy phenomena with subjective qualitative description , closely integrated quantitative analysis and subjective qualitative description.

Modeling the PEV traffic pattern in an urban environment with parking lots and charging stations | In this paper, a mixed-integer linear programing (MILP) model for the traffic behavior of plug-in electric vehicles (PEVs) in an urban environment is proposed. It is assumed that any environment can be categorized into different zones based on their urban functions (e.g. industrial, residential, and commercial). Therefore, the interaction of PEVs that travel between these zones has to be modeled. Besides, it is assumed that in each zone a parking lot (PL) and individual charging stations exist to provide the required state of charge (SOC) for PEVs during their daily travel. As a result, the amount of power that these PEVs consume (rather in PL or charging stations) and the amount of SOC that PEVs carry with them should be precisely computed. The proposed MILP model is applied on two zones urban area with residential and industrial districts and the numerical results prove the proficiency of the model. | Professional Issues Poster Presentation Purpose for the Program I n 2009, Baltimore Washington Medical Center opened the Pascal Women’s Center offering maternal–child services.

The treatment of congenital dislocation and subluxation of the hip in the older child. | Two additional risks are involved in the treatment of congenital dislocation of the hip when diagnosis is made too late: avascular necrosis following the reduction, and residual coxo-femoral dysplasia. Our study and the experience that we acquired within the past 10 years on 142 hips show the value of closed reduction by slow progressive traction with abduction and internal rotation, and the value of innominate osteotomy. These are two strong points on which we can base our treatment in order to further improve the results of our efforts in this field. | This paper presents an exact combinatorial algorithm for solving the Discrete Berth Allocation Problem (DBAP) and the Hybrid Berth Allocation Problem (HBAP) with fixed handling times of vessels based on the original algorithm for solving combinatorial problems called Sedimentation Algorithm. We address the issues of DBAP and HBAP according to the Rashidi and Tsang model. To the best of our knowledge, the proposed algorithm is the first exact combinatorial algorithm for solving the general DBAP and HBAP based on Rashidi and Tsang model. Computational results prove the superiority of the proposed algorithms compared with the exact solvers based on the Mixed Integer Programming (MIP) models. Efficient C implementation enabled us to solve instances with up to 65 vessels. This resolves most of the real life problems, even in large ports. | eng_Latn | 2,897 |

Analysis on Power Allocation Algorithm for Spectrum Overlay | The dynamic spectrum access technology can achieve near-optimal spectrum utilization by allowing cognitive users to sense and utilize available spectrum opportunistically.Based on analysis on two access modes,this paper proposes a spectrum sharing model for spectrum overlay.According to the cognitive users' utility functions,the iterative formulas of cognitive users' power are obtained through water-filling algorithm.And then we obtain the power and sub-carrier allocation results.Simulation analysis show that the iterative algorithm can not only effectively assign the power and sub-carriers between cognitive users,but also can converge in limited time. | This paper presents an adaptation of the adaptive large neighborhood search (ALNS) heuristic in order to solve the crew scheduling problem (CSP) of urban buses. The CSP consists in minimizing the total of crews that will drive a fleet in daily operation as well as the total overtime. The solution for the CSP is a set of duties performed by the crews throughout the day, and those duties must comply with labor laws, labor union agreements, and the company’s operational rules. The CSP is a NP-hard problem and it is usually solved by metaheuristics. Therefore, an ALNS-like heuristic was developed to solve the CSP. Its implementation was tested with real data from a bus company which operates in Belo Horizonte, MG-Brazil, and it provided solutions quite superior to those both adopted by the company and the ones generated by other methods in the literature. | eng_Latn | 2,899 |
