A Problem of Ecological Dynamic Logistics
Authors: Cadenas José M. , Garrido María del Carmen , Martínez Raquel , Muñoz Enrique
Published: October 2013

Companies have to be competitive to survive, offering their customers a more customized and complete service. Moreover, society is increasingly more aware of the need to solve problems in an ecological way trying to reduce pollution/environmental impact. Furthermore, when we try to solve management problems in crowded cities, companies expect their solutions not to depend excessively on traffic conditions and not to have an effect on the worsening of these conditions. In this chapter, the authors study how to handle the aforementioned requirements, defining the problem of ecological dynamic logistics in urban environments. In this problem, a fleet of agile environmentally friendly vehicles have to pick-up and deliver items. However, these vehicles have a limited storage capacity, and they need the support of larger environmentally friendly vehicles, mobile warehouses, to increment their range. The problem is solved by planning the routes for both delivery/pick-up vehicles and mobile warehouses in a coordinated manner, allowing the incorporation of new items during execution of the plan. To obtain a solution for this problem the authors propose to use the Ant Colony Optimization metaheuristic.

Authors: Kougias Ioannis , Patsialis Thomas , Theodossiou Nicolaos , Ganoulis Jacques
Published: October 2013

The interest of those involved in hydroelectricity has been attracted by mini-hydro projects due to their minimal environmental impact and low installation cost. Besides, mini hydros can cooperate with an impressively wide extent of water-related infrastructure, offering a broad potential for investment. In the present chapter, the integrated solution of hydro implementation in water supply systems is presented. Thus, the benefits of a water-supply installation (with constant Q) are extended to energy production. However, defining the optimum operation of such a project is a complicated task, which may involve environmental, hydraulic, technical, and economical parameters. In the present chapter a novel approach is presented, the optimum management of mini hydros in a water supply system with the use of an optimization algorithm (i.e. Harmony Search Algorithm [HAS]). This approach is applied at a site in Northern Greece and is used as a case study of the present chapter.
Modeling and Prediction of Time-Varying Environmental Data Using Advanced Bayesian Methods
Authors: Mansouri Majdi , Dumont Benjamin , Destain Marie-France
Published: October 2013

The problem of state/parameter estimation represents a key issue in crop models, which are nonlinear, non-Gaussian, and include a large number of parameters. The prediction errors are often important due to uncertainties in the equations, the input variables, and the parameters. The measurements needed to run the model and to perform calibration and validation are sometimes not numerous or known with some uncertainty. In these cases, estimating the state variables and/or parameters from easily obtained measurements can be extremely useful. In this chapter, the authors address the problem of modeling and prediction of time-varying Leaf area index and Soil Moisture (LSM) to better handle nonlinear and non-Gaussian processes without a priori state information. The performances of various conventional and state-of-the-art estimation techniques are compared when they are utilized to achieve this objective. These techniques include the Extended Kalman Filter (EKF), Unscented Kalman Filter (UKF), Particle Filter (PF), and the more recently developed technique Variational Bayesian Filter (VF). The original data was issued from experiments carried out on silty soil in Belgium with a wheat crop during two consecutive years, the seasons 2008-09 and 2009-10.

Authors: Konduri Karthik C. , Pendyala Ram M. , You Daehyun , Chiu Yi-Chang , Hickman Mark , Noh Hyunsoo , Waddell Paul , Wang Liming , Gardner Brian
Published: October 2013

This chapter demonstrates the feasibility of applying an integrated microsimulation model of activity-travel demand and dynamic traffic assignment for analyzing the impact of pricing policies on traveler activity-travel choices. The model system is based on a dynamic integration framework wherein the activity-travel simulator and the dynamic traffic assignment model communicate with one another along the continuous time axis so that trips are routed and simulated on the network as and when they are generated. This framework is applied to the analysis of a system-wide pricing policy for a small case study site to demonstrate how the model responds to various levels of pricing. Case study results show that trip lengths, travel time expenditures, and vehicle miles of travel are affected to a greater degree than activity-trip rates and activity durations as a result of pricing policies. Measures of change output by the model are found to be consistent with elasticity estimates reported in the literature.
A Driver’s Mind
Authors: Lützenberger Marco
Published: October 2013

Over the last decade, traffic simulation frameworks have advanced into an indispensible tool for traffic planning and infrastructure management. For these simulations, sophisticated models are used to “mimic” traffic systems in a lifelike fashion. In most cases, these models focus on a rather technical scope. Human factors, such as drivers’ behaviours are either neglected or “estimated” without any proven connection to reality. This chapter presents an analysis of psychological driver models in order to establish such a connection. In order to do so, human driver behaviour is introduced from a psychological point of view, and state-of-the-art conceptualisations are analysed to identify factors that determine human traffic behaviour. These factors are explained in more detail, and their appliances in human behaviour models for traffic simulations are discussed. This chapter does not provide a comprehensive mapping from simulation requirements to particular characteristics of human driver behaviour but clarifies the assembly of human traffic behaviour, identifies relevant factors of influence, and thus, serves as a guideline for the development of human behaviour models for traffic simulations.

Authors: Zhao Yunjie , Sadek Adel W.
Published: October 2013

The focus of this chapter is on issues surrounding the development and applications of large-scale agent-based traffic models. Following a brief overview of Agent-Based Modeling and Simulation (ABMS) applications in transportation modeling, the chapter proceeds to describe the authors’ continued efforts and experiences with the development, calibration, validation, and application of a regional agent-based traffic model of the Buffalo-Niagara metropolitan area. The model is developed using the TRansportation ANalysis SIMulation System (TRANSIMS), an open-source, agent-based suite of transportation models. A unique feature of the chapter is its focus on unplanned or extreme events, such as severe snowstorms and major incidents on the freeways, and how the models may be calibrated and applied under such situations. The chapter concludes by summarizing the main lessons learned from the Buffalo case study and providing suggestions for future research.
Agent-Based Modeling for Carpooling
Authors: Knapen Luk , Yasar Ansar-Ul-Haque , Cho Sungjin , Bellemans Tom
Published: October 2013

Modeling activities and travel for individuals in order to estimate traffic demand leads to large scale simulations. Most current models simulate individuals acting in a mutually independent way except for the use of the shared transportation infrastructure. As soon as cooperation between autonomous individuals is accounted for, the individuals are linked to each other in a network structure and interact with their neighbours in the network while trying to achieve their own goals. In concrete traffic-related problems, those networks can grow very large. Optimization over such networks typically leads to combinatorially explosive problems. In this chapter, the case of providing optimal advice to combine carpooling candidates is considered. First, the advisor software structure is explained; then, the characteristics for the carpooling candidates network derived for Flanders (Belgium) are calculated in order to estimate the problem size.

Authors: Yob Mohd Shukri , Mansor Shuhaimi , Sulaiman Razali
Published: October 2013

In automotive industry, thin walled beam is widely used to build vehicles structure. Vehicle structure is built by joining thin walled beams using various welding techniques. The usage of thin walled structure in automotive is important to improve vehicle performance by offering better strength-to-weight ratio. However the application of thin walled structure will cause few drawbacks to vehicle structure. When thin walled beam or structure is loaded with compression load, at certain limit it will undergo local or global buckling. Another problem is when thin walled beam is joined to other thin walled beams, it will show unexpected deformation which called joint flexibility. Both phenomena will cause numerical and analytical model to predict stiffness of structure tend to deviate from experimental result. In vehicle structure fabrication 3D space frame is used a lot. As a case study for this application, area around car bulkhead where cross member, side sill and A pillar are connected to each other at right angle is studied. The intention of this research work is to produce validated finite element model to predict equivalent stiffness of 3D space frame structural joint. Finite element, shell element is most common technique used to model the joined structure. However it is known that shell model cannot produce good result. In this result work, modelling of equivalent stiffness for 3D space frame structural joint is presented. The result shows, using this model the accuracy is about 65%. New modelling technique is proposed to increase the accuracy based on solid model. By introducing circular beam elements at welding area, it is found that accuracy improves up to 90%.

Authors: Chen Jia Jia , Liu Huan Yu , Zhang Gui Zhen , Qu Jin Ping
Published: October 2013

Vane extruder is a novel equipment in which polymer mainly suffers from elongational deformation. It has the character of short thermal mechanical process so that the biodegradable polymer will less decompose during processing. Different weight ratios of thermoplastic polyurethane (TPU) were blend with polyactide (PLA) in vane extruder. The results show that TPU plays the role of toughening the PLA which is well dispersed in the PLA matrix. From the mechanical properties, for the composite with 40 wt % TPU, the elongation at break of the blend reached 335%. Meanwhile the results observed from DSC curves revealed apparent partial miscibility of the blends and enhanced crystallization ability of PLA due to the influence of elongational flow. From the DMA curves, it could be found that PLA and TPU compatibility of two phases have been improved to some extent because of the elongational deformation.

Authors: Yao Hong Bing , Ma Gui Dian , Tong Yan Qun , Zeng Xiang Bo , Zhen Xue Liang , Jiang Guang Ping , Zhang Yong Kang
Published: October 2013

Aluminum flyer with thickness of 50μm and diameter of 1mm had been driven successfully by high-power Nd:Glass laser system. Average speed of the flyer was detected by piezoelectric Polyvinylidene Fluoride (PVDF) transducer, which reached 6.67km/s. Extent of damage to protective materials of spacecrafts was studied after they were hit by the driven aluminum flyer. The protective materials of spacecraft were damaged structurally in our experiment, and the damage observed under the microscope was also shown. It could be seen that the flyer knocked a tiny hole with diameter of about 1mm in the protective cellular board, and there were traces of impact damage around the tiny hole, which indicated that protective materials of spacecrafts would be damaged structurally when they were hit by flyer with size of 1mm. At the same time, the hyperspeed flyer still had good integrity and flatness. The results showed that laser-shockwave-driven hyperspeed flyer technology could be used as an effective experiment means to simulate high-speed space particles, which made it feasible to establish a set of simulation device of laser-shockwave-driven hyperspeed flyer for the research of protective materials of spacecrafts on the ground.

Structural health monitoring (SHM) systems will be one of the leading factors in the successful establishment of wind turbines in the energy arena. Detection of damage at an early stage is a vital issue as blade failure would be a catastrophic result for the entire wind turbine. In this study the SHM analysis will be based on experimental measurements of vibration analysis, extracted of a 9m CX-100 blade under fatigue loading. For analysis, machine learning techniques utilised for failure detection of wind turbine blades will be applied, like non-linear Neural Networks, including Auto-Associative Neural Network (AANN) and Radial Basis Function (RBF) networks models.

Structural Health Monitoring (SHM) is an emerging field of technology that involves the integration of sensors, data transmission, processing and analysis for detection, as well as localization and assessment of damage which can lead to its failure in the future [1,. In general, SHM methods can be divided into two groups: local and global ones. The second group can be applied if a global change in the geometry of a structure can be observed. In practice, the most commonly used methods of damage detection are based on the analysis of variations in various dynamic properties caused by damage [3,. However, the excitation of large structures can be costly and difficult. The acquisition of static deflection requires much less effort, which makes the damage detection methods based on changes in deflection curves more attractive for practical use [5-1. Damage detection and localization methods require a densely sampled deflection curve.
Simulation and Analysis of Vibration of Rolling Bearing
Authors: Kostek Robert
Published: October 2013

This article presents a non-linear model of deep groove ball bearing and results of simulation. Vibrations of this bearing are studied for a wide range of clearance. An evolution from periodic to chaotic vibrations is visible due to increase of clearance. A number of phenomena associated with non-linear dynamics are observed, for instance: bistability, chaotic vibrations, windows of periodical vibrations, jump of amplitude, period-doubling cascade leading to chaos, bifurcation directly leading to chaos, and self-similarity of a Poincaré section. Moreover, amplitudes of vibrations are presented as functions of clearance. This provides an opportunity to select failure modes. Unfortunately, relations clearance amplitude and amplitude - clearance are ambiguous.

Gears faults are one of the most common issues in rotating machinery. If not detected on time, they may result in severe dysfunction of the kinematic chain or even in catastrophic breakdown of the whole mechanism. Vibration based methods dedicated to gears monitoring are widely studied and applied techniques, that in majority rely on comparison of some spectral features. In this paper, however, the method based on fractal theory and wavelet decomposition is studied for possible application to gears diagnostics. The discussed technique may serve as a tool for signal contraction and/or signals comparison according to frequency content. Presented results are based on experimental data recorded from gradually deteriorated gearbox and gear with mechanically introduced local fault.

Development of effective diagnostic systems for the recognition of technical conditions of complex objects or processes requires the use of knowledge from multiple sources. Gathering of diagnostic knowledge acquired from diagnostic experiments as well as independent experts in the form of an information system database is one of the most important stages in the process of designing diagnostic systems. The task can be supported through suitable modeling activities and diagnostic knowledge management. Briefly, this paper presents an example of an application of multimodal diagnostic statement networks for the purpose of knowledge representation. Multimodal statement networks allow for approximate diagnostic reasoning based on a knowledge that is imprecise or even contradictory in part. The authors also describe the software environment REx for the development and testing of multimodal statement networks. The environment is a system for integrating knowledge from various sources and from independent domain experts in particular.
Contribution to the knowledge of the stag-beetles of the genus Lucanus from Laos, with description of Lucanus marazziorum n.sp. (Coleoptera Lucanidae)
Authors: Zilioli Michele
Published: October 2013

Lucanus marazziorum n.sp. from Laos is described. It belongs to the large group of L. fortunei and is closely related to L. formosus, from which it differs mainly through dorsal teguments glabrous and shape of the mandibles, with their inner tooth placed slightly before the mid-length; moreover through the less transverse head, the stouter aedeagus, with short and slightly apically widened flagellum.

Recent experimental studies revealing new biological effects of tamoxifen on tumor cells both expressing and not expressing different types of estrogen receptors (ERα and ERβ) show new aspects of a seemingly well known agent. This review describes tamoxifen targets, the blocking of which leads to inhibition of tumor cell growth and angiogenesis, stimulation of programmed cell death (apoptosis, autophagia and necrosis), inhibition of multidrug resistance, invasion and metastasis. Since outcomes of tamoxifen action on cells are prognostically good from the point of view of both tumor growth/metastasis inhibition and tumor response to drug therapy, the authors believe this is an extremely important addition to tamoxifen antiestrogenic effect. Arguments are provided to consider the strategy of long-term tamoxifen treatment proposed by Professor Craig V. Jordan in the 1970s that is also applicable to the treatment of other tumors. This is, first of all, the fact that expression of estrogen receptor-beta that can also be targeted by tamoxifen therapy in solid tumors of practically all known sites and histologies. The authors believe that molecular biological screening of patients with respect to expression of tamoxifen cellular targets other than ERα and ERβ is needed to use to the full all tamoxifen biological activities other than modulation of estrogen receptors during long-term adjuvant therapy for cancers of various sites.
Radio-protective role of antioxidant agents

Ionizing radiation interacts with biological systems to produce reactive oxygen species and reactive nitrogen species which attack various cellular components. Radio-protectors act as prophylactic agents to shield healthy cells and tissues from the harmful effects of radiation. Past research on synthetic radio-protectors has brought little success, primarily due to the various toxicity-related problems. Results of experimental research show that antioxidant nutrients, such as vitamin E and herbal products and melatonin, are protective against the damaging effects of radiation, with less toxicity and side effects. Therefore, we propose that in the future, antioxidant radio-protective agents may improve the therapeutic index in radiation oncology treatments.
