Abstract In contrast to conventional routing systems, which determine the shortest distance or the fastest path to a destination, this work designs a route planning specifically for electric vehicles by finding an energy-optimal solution while simultaneously considering stress on the battery. After finding a physical model of the energy consumption of the electric vehicle including heating, air conditioning, and other additional loads, the street network is modeled as a network with nodes and weighted edges in order to apply a shortest path algorithm that finds the route with the smallest edge costs. A variation of the Bellman-Ford algorithm, the Yen algorithm, is modified such that battery constraints can be included. Thus, the modified Yen algorithm helps solving a multi-objective optimization problem with three optimization variables representing the energy consumption with (vehicle reaching the destination with the highest state of charge possible), the journey time, and the cyclic lifetime of the battery (minimizing the number of charging/discharging cycles by minimizing the amount of energy consumed or regenerated). For the optimization problem, weights are assigned to each variable in order to put emphasis on one or the other. The route planning system is tested for a suburban area in Austria and for the city of San Francisco, CA. Topography has a strong influence on energy consumption and battery operation and therefore the choice of route. The algorithm finds different results considering different preferences, putting weights on the decision variable of the multi-objective optimization. Also, the tests are conducted for different outside temperatures and weather conditions, as well as for different vehicle types.

Fire brigades and other specialized agencies are often required to undertake extremely dangerous search and rescue operations in which it is important first to verify the safety of the environment and then to obtain clear remote images of the inside of buildings and underground areas. Several studies have addressed the possibility of using robotic tools to make such operations safer for operators and more efficient in time and resource allocations. This paper describes the development of the HELIOS team, consisting of five tracked urban search and rescue robots. Two of these have arms and grippers for specialized tasks, such as handling objects and opening doors. The other three use cameras and laser range finders to construct virtual 3D maps of environment explored, moving autonomously while collecting data using a Cooperative Positioning System (CPS). After introducing robot team specifications, we detail mechanical robot design and control systems. We then present test results for the CPS and HELIOS IX vehicle together with typical mission experiments.

Abstract This paper examines police militarization in Canada between 2007 and 2017. We contrast media and police accounts of militarization with special weapons and tactics (SWAT) team deployment records disclosed under freedom of information (FOI) law. Discourse analysis reveals a series of armoured vehicle purchases has been justified by police claims about the danger faced by police officers, and the need to keep police officers and the public safe. Media and police accounts thus suggest militarization is limited. However, our FOI research shows planned and unplanned deployment of SWAT teams have risen in major Canadian cities and are higher in some cases than those reported by Kraska on public police militarization in the USA. After revealing this juxtaposition between media rhetoric and the organization and operational reality of police militarization, we reflect on the implications of police militarization in Canada and the challenges that police may face in communications about armoured vehicle purchases as public awareness of SWAT team use rises and police legitimacy is questioned.

AbstractThis article outlines the evolution of a rescue team in responding to adenovirus prevention with a deployable field hospital. The local governments mobilized a shelter hospital and a rescue team consisting of 59 members to assist with rescue and response efforts after an epidemic outbreak of adenovirus. We describe and evaluate the challenges of preparing for deployment, field hospital maintenance, treatment mode, and primary treatment methods. The field hospital established at the rescue scene consisted of a medical command vehicle, a computed tomography shelter, an X-ray shelter, a special laboratory shelter, an oxygen and electricity supply vehicle, and epidemic prevention and protection equipment. The rescue team comprised paramedics, physicians, X-ray technicians, respiratory therapists, and logistical personnel. In 22 days, more than 3000 patients with suspected adenovirus infection underwent initial examinations. All patients were properly treated, and no deaths occurred. After emergency measures were implemented, the spread of adenovirus was eventually controlled. An emergency involving infectious diseases in less-developed regions demands the rapid development of a field facility with specialized medical personnel when local hospital facilities are either unavailable or unusable. An appropriate and detailed prearranged action plan is important for infectious diseases prevention. (Disaster Med Public Health Preparedness. 2018;12:109–114)

<p><strong>Abstract.</strong> Efficient and effective spatial data collection is crucial in cases of catastrophic events. Resources efficiency and project effectiveness are two aspects that need special attention especially when there are spatial and temporal constraints. There is limited literature regarding efficiency and effectiveness in spatial data collection approaches. This work elaborates on the collection of spatially-aware data from a diverse scientific group of teams after the catastrophic earthquake of Mw&thinsp;=&thinsp;6.3 in Vrisa village, Lesvos island in Greece in June 2017. More specific we deal with challenges faced by six teams of experts (Topographic team, House conditions data collection team, Unmanned Aerial Vehicle team, 3D Laser Scanner team, Photogrammetry team and Privacy team). The scientific teams had to collect accurate spatial data for the same area, during a period of 20 days after the earthquake. That was a challenging task due to restrictions in the area and complexity/diversity of spatial data. We present the methodological approaches followed for efficient and effective data-capturing, and we propose a framework of team/data management under concurrent data collection by scientific teams after catastrophic events such as earthquakes.</p>

In this paper, we solve a discrete-time bearing-only cooperative localization problem for a team of autonomous vehicles with a special focus on switching sensing topology. A centralized Extended Kalman Filter (EKF) is used for jointly estimating position and heading of all the vehicles using local motion and relative bearing measurements. We derive discrete-time conditions for switching relative sensing topology. Furthermore, we use cooperative synchronization for generating vehicle paths that satisfy the observability conditions. The conditions are verified through simulation and experimental results.

Abstract Faith-based organizing in the United States faces two major practical challenges: funding its work and teaching its approach to the next generation of pastors. With these challenges in mind, the editors asked Sheila Greeve Davaney, until recently a programme officer with the Ford Foundation, to reflect on her experience of funding the work of faith-based organizing networks. John Bowlin, a professor at Princeton Theological Seminary and Jarrett Kerbel, a pastor in Philadelphia, recently team taught a course on theology and organizing at the seminary; the editors asked them to reflect on their classroom experience. Their experience was enriched by the presence of Elizabeth Valdez, an organizing network leader from Texas, who was on sabbatical in Princeton at the time, and was invited by Bowlin, while she audited his class, to share her grass-roots experience with the students. It is fitting that Valdez has the last word in this special issue, as an organizer who is committed to the goal of fostering dialogue between theologians and researchers in the academy and citizens and leaders in the community.

Full textAbstract:
La pollution sonore est un problème majeur pour les résidents des zones urbaines. La directive Européenne 2002/49/CE impose aux états membres l’établissement de cartes de bruit. Ces dernières sont construites sur la base de l’indice énergétique Lden, également utilisé dans les relations dose-effet établies pour prédire la gêne. Toutefois, pour l’évaluation de la gêne due au bruit dans les zones urbaines, la pertinence de cet indice est souvent remise en question. En effet, de nombreuses études ont montré que les caractéristiques temporelles et spectrales des bruits environnementaux influencent aussi les réponses de gêne et ne sont pas prises en compte dans cet indice. Cette thèse vise à contribuer à l’amélioration de la caractérisation de la gêne due au bruit des véhicules routiers en ville. Elle est basée sur des expériences réalisées en laboratoire. Elle comprend deux parties principales. La première partie a comme objectif de progresser sur la caractérisation physique et perceptive du bruit des passages de divers véhicules routiers en milieu urbain tels que les bus, les deux-roues motorisés, les poids lourds et les véhicules légers. Une attention particulière a été portée sur la caractérisation de la gêne due aux deuxroues motorisés qui sont cités parmi les véhicules routiers les plus gênants et sont peu étudiés dans la littérature. Dans cette perspective, un indicateur acoustique caractéristique de la gêne due au bruit routier urbain a été déterminé : il rend compte de différents attributs auditifs gênants en associant la sonie, un indice spectral et deux indices de modulation proposés dans le cadre de ces travaux. Dans les zones urbaines, les riverains sont souvent exposés à la circulation routière en présence d’autres sources de bruit de l’environnement. L’objectif principal de la deuxième partie est la prédiction de la gêne totale due au bruit du trafic routier urbain combiné avec le bruit de tramway. Dans le but de caractériser la gêne totale, les phénomènes perceptifs liés à la combinaison de ces bruits sont tout d’abord étudiés. Ensuite, l’indicateur proposé précédemment pour caractériser la gêne due au bruit des passages de différents véhicules routiers est testé lorsque différents trafics routiers urbains sont considérés. Sur la base de ces résultats, des modèles permettant de caractériser la gêne due au bruit de trafic routier urbain combiné au bruit de tramway ont été proposésNoise pollution is a major concern for residents of urban areas. To date, the European directive 2002/49/CE requires member states to represent community noise through noise maps. These are produced using the Lden (day-evening-night level) index which is also employed for dose-effect relationships in noise annoyance prediction. However, for the assessment of noise annoyance in urban areas, its relevance is often questioned. Numerous studies have shown that noise annoyance due to community noise is not solely based on the sound pressure level and other acoustical signal characteristics such as temporal and spectral features influence noise annoyance ratings. This thesis aims to improve the assessment of noise annoyance due to various road vehicle noises in cities. It is based on experiments carried out in laboratory conditions and comprises two main parts. The first addresses the enhancement of the physical and perceptual characterization of annoyance due to various urban road vehicle pass-by noises, such as buses, poweredtwo- wheelers, heavy vehicles and light vehicles. A specific focus is put on the characterization of annoyance due to powered-two-wheelers which are among the most annoying road vehicles and studied little in the existing literature. An indicator accounting for annoyance-relevant auditory attributes of urban road vehicle pass-by noises is determined: it comprises loudness, a spectral index and two modulation indices proposed in this work. In urban agglomerations, people are often exposed to road traffic in presence of a variety of other environmental noise sources. The focal point of the second part is on the prediction of total annoyance due to urban road traffic noise combined with tramway noise. In the aim of adequately characterizing total annoyance, first the perceptual phenomena involved in annoyance due to the combination of the sources are studied. Furthermore, the analysis allows for the testing of the proposed noise annoyance indicator for the characterization of urban road traffic noise. To characterize annoyance due to tramway noise, an indicator determined in a recent study is employed. Based on these indicators and the findings regarding perceptual phenomena, models for the prediction of total annoyance due to combined urban road traffic and tramway noise are proposed

Full textAbstract:
The term ‘polytrauma’ refers to blunt (or crush) trauma that involves multiple body regions or cavities, and compromises physiology to potentially cause dysfunction of uninjured organs. Polytrauma frequently affects muscles resulting in rhabdomyolysis. In daily life, it mostly occurs after motor vehicle accidents, influencing a limited number of patients; after mass disasters, however, thousands of polytrauma victims may present at once with only surgical features or with additional medical complications (crush syndrome). Among the medical complications, acute kidney injury (AKI) deserves special mention, since it is frequent and has a substantial impact on the ultimate outcome.Several factors play a role in the pathogenesis of polytrauma (or crush)-induced AKI: (1) hypoperfusion of the kidneys, (2) myoglobin-induced direct nephrotoxicity, and intratubular obstruction, and also (3) several other mechanisms (i.e. iron and free radical-induced damage, disseminated intravascular coagulation, and ischaemia reperfusion injury). Crush-related AKI is prerenal at the beginning; however, acute tubular necrosis may develop eventually. In patients with crush syndrome, apart from findings of trauma, clinical features may include (but are not limited to) hypotension, oliguria, brownish discoloration of urine, and other symptoms and findings, such as sepsis, acute respiratory distress syndrome, disseminated intravascular coagulation, bleeding, cardiac failure, arrhythmias, electrolyte disturbances, and also psychological trauma.In the biochemical evaluation, life-threatening hyperkalaemia, retention of uraemic toxins, high anion gap metabolic acidosis, elevated serum levels of myoglobin, and muscle enzymes are noted; creatine phosphokinase is very useful for diagnosing rhabdomyolysis.Early fluid administration is vital to prevent crush-related AKI; the rate of initial fluid volume should be 1000 mL/hour. Overall, 3–6 L are administered within a 6-hour period considering environmental, demographic and clinical features, and urinary response to fluids. In disaster circumstances, the preferred fluid formulation is isotonic saline because of its ready availability. Alkaline (bicarbonate-added) hypotonic saline may be more useful, especially in isolated cases not related to disaster, as it may prevent intratubular myoglobin, and uric acid plugs, metabolic acidosis, and also life-threatening hyperkalaemia.In the case of established acute tubular necrosis, dialysis support is life-saving. Although all types of dialysis techniques may be used, intermittent haemodialysis is the preferred modality because of medical and logistic advantages. Close follow-up and appropriate treatment improve mortality rates, which may be as low as 15–20% even in disaster circumstances. Polytrauma victims after mass disasters deserve special mention, because crush syndrome is the second most frequent cause of death after trauma. Chaos, overwhelming number of patients, and logistical drawbacks often result in delayed, and sometimes incorrect treatment. Medical and logistical disaster preparedness is useful to improve the ultimate outcome of disaster victims.

AbstractIn Part III, titled “City Planning and New Technology,” we discuss two topics, namely, compact cities and real estate technology in Japan.Promotion of compact cities is regarded as a high priority issue in urban policies in the era of population decrease. The Act on Special Measures concerning Urban Reconstruction in 2014 was revised to institutionalize the framework for the Location Normalization Plan, a plan for local governments to build compact cities to manage population decline and aging urban infrastructure while placing less burden on environment. Three chapters are devoted to issues related to this movement. In Chap.10.1007/978-981-15-8848-8_18, Ishikawa (2020) discusses how urban functions can be guided by residents’ perspectives. To build a compact city, various day-to-day services must be placed proximal to residential areas; however, some services must be placed at a certain distance from residences because of land use restrictions. Therefore, we must determine the uses allowed in residential areas. In Chap.10.1007/978-981-15-8848-8_19, Morimoto (2020) discusses the history of major contributions made by the development of transportation facilities to urban spread, the important role of traffic facilities to guide land use toward desirable purposes, and impact of self-driving vehicles on land use. In Chap.10.1007/978-981-15-8848-8_20, Ogushi (2020) explains how the Location Normalization Plan in Niigata City was formed in detail.Real estate technology refers to real estate business-related services that use new technology. Several new services based on new technology have been introduced in the field of real estate in Japan. Three chapters are devoted to issues related to real estate technology. In Chap.10.1007/978-981-15-8848-8_21, Narimoto (2020) explains the outline of real estate technology services in Japan and identifies legal problems associated with handling of information. In Chap.10.1007/978-981-15-8848-8_22, Nishio and Ito (2020) report on creating a sky view factor calculating system that uses Google Street View. Sky view factor is a term that refers to a configuration factor for the amount of sky in a hypothetical hemisphere. In Chap.10.1007/978-981-15-8848-8_23, Kiyota (2020) explains the transition of neural network research and characteristics of deep learning and introduces a system that detects category inconsistencies in real estate property photographs submitted by real estate companies by using deep learning and a system that detects indexes associated with ease of living based on property photographs.

Micro, Small, and Medium Enterprises (MSMEs) have emerged as a vehicle of economic growth in several emerging countries in the world. The SMEs significantly impact nations' growth in terms of their contribution to exports, employment generation, and Gross Domestic Product (GDP). It has been witnessed that these small enterprises help countries to sustain in times of economic recession. This chapter presents the significance of MSMEs, a critical review of the challenges they face, and the futuristic vision which is required by these firms so as to multiply their economic contribution in special reference to India. The chapter would serve as a resource for policy makers while bringing attention of key stakeholders to the potential of SMEs in paving the future growth curve for emerging economies in the global context. Through a critical review of secondary literature, the chapter also discusses the vision for the future which is needed for SMEs to achieve the various long-term objectives keeping in view the dynamic external environment where the world is a global village.

Abstract This paper documents the vehicle modeling and fuel economy simulation efforts for the Georgia Tech EcoCAR Mobility Challenge team during Year 1 of the current Advanced Vehicle Technology Competition (AVTC). The goal of the first year of the competition was to propose two possible hybrid electric vehicle (HEV) architectures based on a 2019 Chevrolet Blazer platform that could be built and refined throughout Years 2–4 of the competition. A Simulink vehicle model was used to compare a variety of HEV architectures with several different combinations of engines, batteries, and electric machines. An adaptive Equivalent Consumption Minimization Strategy was used to split torque between the internal combustion engine and two electric machines so that architectures with two electric machines could be modeled. The model was validating by comparing results from simulating a conventional Chevrolet Blazer with the 2.5L naturally aspirated engine to fuel economy results obtained by the Environmental Protection Agency (EPA). In addition to developing a hybrid vehicle, the competition is focused on exploring Mobility as a Service (MaaS), which introduces some special considerations when choosing a hybrid vehicle architecture. The results of the Simulink model as well as requirements set by the MaaS market led the Georgia Tech EcoCAR team to pursue a dual electric machine P0P4 parallel through the road hybrid vehicle.

This paper, was originally prepared for and presented at the 2008 AUVSI Student UAS Competition, it provides the OSAM-UAV (Open-Source Autonomous Multiple Unmanned Aerial Vehicle) team’s design of an unmanned aircraft system for remote target recognition missions. Our OSAM-UAVs are designed to be small in size with strong airframes, and low-cost using open-source in both autopilot hardware and flight control software. A robust EPP-based delta wing airframe is used to prevent damage to the airframe during landing or even crashes. Autonomous navigation is achieved using an open-source Paparazzi autopilot, which gives special attention to safety during operation. Our system has been further enhanced by using the Xbow MNAV Inertial Measurement Unit (IMU) in place of the Paparazzi’s standard infrared (IR) sensors, for better georeferencing. An array of light-weight video cameras have been embedded in the airframe, which stream video to the ground control station through wireless transmitters in real-time. The ground control system includes a computer vision system, which processes and geo-references images in real-time for target recognition. Experimental results show the successful autonomous waypoint navigation and real-time image processing.

Student Team Challenges on specific topics are growing in popularity as efficient ways to stimulate students’ independent work, technical and management learning as well as socialization and internationalization. Many competitions are focused on ground vehicles (SAE Formula, Motostudent, Shell Eco Marathon, Solar Challenge), with different focuses on performance, fuel consumption or other depending on the aim of the event. An interesting approach is proposed in the United States by the ASME HPV Challenge, which is focused on Human Powered Vehicles. This class of vehicles allows not only to set-up a classical competition in terms of design, innovation, presentation, manufacturing and racing, but also to grow the student awareness about speed-energy relation. An HPV gives to the rider a direct feedback on a “human-scale” about energy quantities involved in personal mobility. The main returns by the use of this specific topic for a student challenge are: better understanding of the sustainable mobility problem, awareness about the potential and the limits of human muscular power, development of technical skills about design and engineering of lightweight and efficient vehicles, stimulation of the HPVs market development (the students are both potential future designers/manufacturers and/or customers), promotion of healthy and engaging physical activities. In this context, while Europe is rich of HPVs amateurs and manufacturers and is the usual location of the WHPVA World Championship, there is a lack of an educational framework involving students and teachers. Starting from the end of ZEV-HPV Erasmus Intensive Program 2011–2013, the proposal of creating a specific HPV challenge for the European students was developed by the authors. In particular, it was evaluated that by integrating the Student Challenge in the WHPVA World Championship as a special “Educational” category, many reciprocal advantages could be obtained: logistic and organizational support from the WHPVA and its national representatives, in particular for racing and timing, reciprocal technical and cultural exchange between students, academics and the hundred of amateur rider/designer/builder that were attending the event in the last decade, growth and renewal of the European HPVs community by aggregating young people around the subject and by stimulating the research of innovative solutions. After an in-depth analysis of the arguments reported above, an overview of the rules for the 1st edition of EU HPV Student Challenge will be presented and compared to analogous international competitions from an educational perspective.

Abstract Unmanned aerial vehicles (UAV) have a great potential for geological exploration optimization at all stages. This study considers UAV implementation at different exploration stage. Integrated approach using unmanned aerial systems shows great effectiveness based on the completed surveys. Low-depth electrical exploration using the shallow electrical exploration method is one of the possible UAVs technologies with great potential. In this study there are several cases describing main field data acquisition, models and cross-sections processing. Unmanned aerial systems are applicable at all stages of the oil and gas value chain and are already an integral part of oil&gas production process. Now there are more than 70 unmanned aerial systems application scenarios. The main advantages of drones are that the use of this operational data collection tool allows: – to reduce the duration of collecting geospatial data by 70%, and the cost by 3 times; – make the best decisions quickly; – to realize additional potential for increasing efficiency (application at all stages of the production chain) – increase the production processes safety level The most promising and actively developing areas of technology application are: Geophysical surveys at different stages of geological exploration. Drones have great potential for application in non-seismic exploration methods in the early stages of geological exploration. In addition, UAV surveys are suitable for planning geological exploration and working out the conceptual arrangement of the terrain. The presence of an accurate digital elevation model at the start of work of the project team makes it possible to remove a number of uncertainties and questions about conducting field work on seismic exploration, the placement of infrastructure and corridor communications. Objective control of the capital construction progress. Another important area of drones application is aerial photography at all stages of capital construction. With the help of UAVs, it is possible to control such parameters as the status and quality of construction and installation works, equipment of contractors, compliance with safety and environmental standards, and others. To do this, the unmanned vehicle flies around the object with a given regularity, filming it from different angles. After aerial photography, special software stitches the results into photogrammetric products (digital terrain model, orthophotomaps, 3D models) with an accuracy of 4–6 centimeters. On the constructed models, you can calculate the dynamics by one or another parameter. Operational fieldwork and intrastructure monitoring. At the same time, one of the key goals of technology application is the creation of a network of autonomous stations with drones at all assets for remote control of the company's production processes. The first step in this direction was the joint pilot testing of an automated take-off and landing station with an unmanned aerial vehicle of a multi-rotor type. The use of the station will reduce the time and cost of collecting data on capital construction and infrastructure. Project teams will be able to react faster to changes. An automated take-off and landing station allows the use of unmanned aerial vehicles without human intervention. The drone can independently take off, perform the necessary operations, land and recharge. Thus, flight operations and data collection can be performed remotely without the constant presence of a specialist on site.

The need to decrease pollution in urban zones has pushed toward severe regulations in term of low-emission limits. The effect of this “environmental awareness” is an increased interest in electric vehicles (EV). The construction of a EV is presented in the paper. This vehicle has been designed specifically to be powered by electric motors, the suspension system and the general layout have been developed accordingly. According to the European technical regulations, the vehicle has been designed for a city use. The main features of GreenFun, (this is the name of the prototype), are an extensive use of composite and lightweight materials, a special suspension system layout, a 4WD powertrain realized by means of 4 electric motor hubs and the use, for the first time in a production vehicle, of 4 measuring wheels that are able to measure the forces acting between the pneumatic tires and the road. These information are used as input for the vehicle control systems in order to enhance performance and safety. In the paper, the most relevant vehicle subsystems are described in detail (chassis, wheel, suspensions, powertrain, energy management, control system, …).

Full textAbstract:
Mass transit systems are gaining increased attention and popularity in the country. With this increased activity, more and more lines are getting added under public transit systems in more and more cities. One of the essential elements in the transit system is the traction transformer which powers the trains. With the emphasis on reliability, there is also increased awareness of the energy efficiency required of the traction substation equipments and the transformer in particular. Traction transformers are not ordinary power or distribution transformers. They have to meet several special requirements, including parameters like voltage regulation, impedance, commutation, short circuit withstand, operation with rectifiers, harmonic losses, wide fluctuation of load currents depending on the cyclic nature, etc. The reliability criteria are stringent and the traction transformers have to be properly designed, manufactured and tested, including short circuit testing for validation. Use of modern design tools like electric and magnetic field mapping and estimation of forces and stresses are helpful in computing them accurately. With the extensive use of vacuum circuit breakers, the subject of interaction of transformers and breakers have come to the foreground. New standards (like IEEE C57.142) have come into existence, which recommend methods to mitigate such effects. The author of this paper and his team has successfully applied these techniques in real life situations to solve problems. Work is in the final stages for preparation of a standard specifically for Traction Power Rectifier Transformers for transit applications (IEEE draft standard 1653.1) under the IEEE Vehicle Standards Committee.

Full textAbstract:
Ride comfort is one of the most important criteria by which people judge the total quality of the car. Traditionally to investigate the vehicle ride comfort, some well-known classical lumped-mass models are used. In these models such as quarter car model, half car model and full vehicle model, body flexibility has been ignored and sprung mass (vehicle body) assumed to be rigid. This assumption can reduce the model accuracy, specially in the case of long vehicles such as vans, buses and trucks. To impose body flexibility in the ride analysis, recently some numerical FEM-based models have been introduced, but they are complex and non-parametric. In this paper the effects of body flexibility on the vehicle vibration behavior has been studied based on an analytical approach. For this purpose, a new simple and parametric lumped-mass 8 DOF model has been developed. Comparison of the results of natural frequency analysis and forced vibration analysis for this model with the corresponding results of so called “rigid model” or “classic model” is very informative. As the results are shown, body flexibility strongly influenced on the acceleration and displacement responses of the vehicle so that it is necessary to considering this term at the early stages of the vehicle design.

An impossibility to foresee in advance the accurate traffic parameters in face of dynamism phenomena in complex transportation system is a one of the major source of uncertainty. The paper presents an approach to robust optimization of logistics vehicle routes in urban areas on the basis of estimated short-term traffic time forecasts in a selected area of the urban road network. The forecast values of optimization parameters have been determined using the spectral analysis model, taking into account the forecast uncertainty degree. The robust counterparts approach of uncertain bi-criteria shortest path problem formulation is used to determining the robust routes for logistics vehicles in the urban network. The uncertainty set is created on the basis of forecast travel times in chosen sections, estimated by means of spectral analysis. The advantages and the characteristics are exemplified in the actual Krakow road network. The obtained data have been compared with classic approach wherein it is assumed that the optimization parameters are certain and accurate. The results obtained in the simulation example indicate that use of forecasting techniques with robust optimization models has a positive impact on the quality of final solutions.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3512

Nowadays, magnetic materials are receiving special attention due to their potential applications in different fields and in particular in medicine. Magnetic micro-nano-particles have been progressively employed as support materials for enzyme immobilization, and have been used as drug-delivery vehicles, contrast agents for magnetic resonance imaging as well as heat mediators for hyperthermia-based anti-cancer treatments and many other exciting biomedical applications. Magnetic materials have also attracted a big interest in the field of bone tissue regeneration because it has been demonstrated that magnetic nanoparticles have effect of osteoinduction even without external magnetic force. Therefore, one of the most big challenge in this field is the production of magnetic materials with good biocompatibility and biodegradability. In fact, the long-term effects in the human body of iron oxide (maghemite or magnetite), the most popular magnetic phase used in medicine and biotechnology, are not yet completely assessed. To this aim, in this work we developed an innovative biocompatible and bioresorbable superparamagnetic-like phase by doping nano-hydroxyapatite with Fe2+/Fe3+ ions (FeHA). Moreover the same magnetic nanoparticles were used as nano-particulate emulsifier for the preparation of hollow hybrid Fe-HA-poly(L-lactic) acid (PLLA) micro-nano-spheres. PLLA has been used because poly(α-hydroxy-esters) are the most frequently used synthetic polymers for biomedical applications owing to their biocompatibility, hydrolytic degradation process and proper mechanical properties. These micro-nanospheres could be used as new type of scaffold for hard tissue regeneration. In fact, spherical scaffold display several advantages respect to the monolithic counterpart e.g., (i) improving control over sustained delivery of therapeutic agents, signalling biomolecules and even pluripotent stem cells, (ii) serving as stimulus-sensitive delivery vehicles for triggered release, (iii) introducing porosity and/or improve the mechanical properties of bulk scaffolds by acting as porogen or reinforcement phase, (iv) supplying compartmentalized micro-reactors for dedicated biochemical processes, (v) functioning as cell delivery vehicle, and, finally, (vi) giving possibility of preparing injectable and/or mouldable formulations to be applied by using minimally invasive surgery. Moreover, the same magnetic materials could find applications in nanomedicine as a multifunctional carrier. Their magnetic functionality could be utilized to move them into the body towards target organs by an external magnetic field. Furthermore, the superparamagnetic feature of the nanoparticles could allow to tailor the release of the therapeutic agent by switching (on-off) the external magnetic field and/or to treat cancer cells by hyperthermia.

The NASCAR Truck Aerodynamic Improvement team is tasked with providing aerodynamic analysis and improvement to Ford Performance and their factory supported team Brad Keselowski Racing for their Ford F-150 race trucks. A Ford F-150 race truck is a “stock” truck that has some modifications for racing speed and safety. Ford Performance, reached out to an MSOE student and asked if a Senior Design team and project could be assembled to provide them with some aerodynamic analysis and improvements that would not require them to build and test using a trial-and-error type method resulting in expensive, and real, testing. The purpose of this project was to conduct a computational fluid dynamic analysis on the truck and make design changes to the truck that will provide more down force on the front two tires. The areas of the truck that were studied included the side panels, deck lid, rear quarter panels, and frontal geometry. There were also constraints put in place by the NASCAR rulebook on the vehicle specifications. These rules limit the design changes that were made to the truck. The model was originally sent as a laser scanned STL file. This file needed to be heavily edited in order to be imported into the CFD program. The programs used to edit this file include Geomagic, Autodesk Fusion 360, and SolidWorks. Through using these programs, the laser scan file was modified to a usable format. Upon conclusion of the CFD simulations using ANSYS Fluent, it was found that the truck with no geometry changes displayed a drag coefficient of 0.489 and a lift coefficient of −0.815. These results were found after 10,000 iterations of testing. The standard deviation in the drag and lift coefficients were 0.00743 and 0.01660 respectively. All statistical calculations along with the averaged solutions were calculated using the data after the 2,500th iteration. This is because the nature of the CFD solutions tend to fluctuate greatly at first and then slowly converge with more iterations. After the 2,500th iteration, a relatively steady state in the solutions is met where the residuals are converging to a single value or the fluctuation in the solutions is repetitive. The following design changes were made in attempt to increase the down force on the truck. A rib was added to the side panel in order to increase the downforce on the truck. The side panel was also modified with a cut. The contour on the rear deck lid was smoothed in order to decrease drag on the truck. Slots were cut out of the shell of the truck behind the rear wheels on both sides of the truck. These slots were angled in an attempt to create down force on the rear wheels. The front splitter was lowered closer to the ground in attempt to increase air velocity moving under the truck. This higher velocity air would create a lower pressure region under the car which would increase down force. All of these modifications were applied to the initial truck body and tested using the same setup as the baseline. The most successful design change was the rear deck lid modification which resulted in a drag coefficient of 0.472 and a lift coefficient of −0.816. This is a 3.48% decrease in the drag coefficient and a 0.12% decrease in the lift coefficient (or 0.12% increase in downforce). The results of this project were purely simulation based; any real modifications and field testing made will be performed by Brad Keselowski Racing and Ford Performance.
