Texto completoResumen
This paper presents an analysis of red light running (RLR) conducted at saturated intersections in the city of Mumbai, India, where the traffic is highly heterogeneous with respect to vehicle classes and driver behavior. When all vehicles are considered, almost one in 17 drivers is seen to be jumping red signals there. Unlike the RLR behavior that has been previously reported from intersections elsewhere, a peculiarity observed here is that, within a single red phase, two distinguishable segments of RLR behavior exist. The authors classified them into two regimes: Regime 1, just after the onset of red, and Regime 2, just before the onset of the next green. About one-third of RLR events occur in Regime 1 and the rest in Regime 2. The authors fit different distributions on the time distribution of RLR events. The Kolmogorov–Smirnov test suggests that, at all intersections, exponential distribution fits best for RLR behaviors in Regime 1, and extreme value distribution fits for Regime 2. In addition to those two regimes, RLR at a lower rate is observed in the period between those regimes, and normal distribution fits there. To analyze the causal factors of RLR behavior in the two regimes, the authors developed models at a mesoscopic level specific to vehicle class and regime. Although the red-to-green ratio and the presence of policing prove to be relevant factors affecting RLR in both the regimes, the relative time for which the conflict area is free affects RLR in Regime 2 but not in Regime 1.

Purpose The purpose of this paper is to investigate the main causes of delay in public construction projects. This is motivated by feedback from public construction experts concerning substantive delays during the last decade. The study thus seeks to help decision makers in Jordan and elsewhere identify problems and develop mitigating strategies. Design/methodology/approach Causes of delay were identified from previous related studies and then augmented after consultation with experts. This resulted in 56 delay factors classified into eight groups. The sampling frame for the study was defined in terms of public construction projects (mostly related to roads) owned by the Ministry of Public Works and Housing in Jordan. A survey was conducted with engineers working as representatives of the owner, contractors or consultants to elicit and evaluate the importance of the 56 delay factors. Findings Overall, 113 completed questionnaire responses were returned and analyzed to rank the causes of delay using the relative importance index method. Owners and consultants showed more interest in factors related to themselves, while contractors showed highest interest in an external factor related to the owner of services. Four recommendations are put forward for decision makers to mitigate against delays. Originality/value This research investigates a relatively large number of delay factors compared to other studies and these are categorized into groups to facilitate thematic understanding. Further, compared to previous related research, this research fills a gap by exploring the opinions of different contract parties.

Buscar texto completoResumen
<div>Nature has evolved efficient strategies to make materials with hierarchical internal structure that often exhibit exceptional mechanical properties. One such example is found in cellulose, which has achieved a high order of functionality and mechanical properties through a hierarchical structure with an exceptional control from the atomic level all the way to the macroscopic level. Cellulose is present in a wide variety of living species (trees, plants, algae, bacteria, tunicates), and provides the base reinforcement structure used by organisms for high mechanical strength, high strength-to-weight ratio, and high toughness. Additionally, being the most abundant organic substance on earth, cellulose has been used by our society as an engineering material for thousands of years, and are prolific within our society, as demonstrated by the enormity of the world-wide industries in cellulose derivatives, paper/packaging, textiles, and forest products.</div><div><br></div><div><div>More recently, a new class of cellulose base particles are being extracted from plants/trees, cellulose nanocrystals (CNCs), which are spindle-shaped nano-sized particles (3 ̶ 20 nm in width and 50 ̶ 500 nm in length) that are distinct from the more traditional cellulose materials currently used (e.g. molecular cellulose and wood pulp). They offer a new combination of particle morphology, properties and chemical functionalities that enable CNCs for use in applications that were once thought impossible for cellulosic materials.</div></div><div><br></div><div><div>CNCs have shown utility in many engineering applications, for example, biomedical, nanocomposites, barrier/separation membranes and cementitious materials. To gain greater insight as to how best use CNCs in various engineering application areas, a comprehensive understanding of the mechanics of CNCs is needed. The characterization of the mechanical properties of nanomaterials via experimental testing has always been challenging due to their small size, resulting in large uncertainties related to testing near sensitivity limits of a given technique, the same is true when characterizing CNCs. For CNCs, to help offset limitations in experimental testing, numerical modeling has been useful in predicting the mechanical properties of CNCs. We present a continuum-based structural model to study the mechanical behavior of cellulose nanocrystals (CNCs), and analyze the effect of bonded and non-bonded interactions on the mechanical properties under various loading conditions. In particular, this model assumes the uncoupling between the bonded and nonbonded interactions and their behavior is obtained from atomistic simulations.</div></div><div><br></div><div><div>For large deformations and when there is interaction and dynamics of many particles involved, continuum models could become as expensive as MD simulations. In addition, it has been shown that traditional material models in the continuum mechanics context, cannot model all the mechanical properties of CNC, especially for large deformation. To overcome these setbacks and to be able to model real size of CNC, 50-1000 nm, and/or to increase the number of particles involved in the simulation, a so called ‘‘coarse-grained’’ (CG) model for mechanical and interfacial properties of CNC is proposed. The proposed CG model is based on both mechanical properties and crystal-crystal interactions. Parametrization of the model is carried out in comparison with all-atom (AA) molecular dynamics and experimental results of some specific mechanical and interfacial tests.</div></div><div><br></div><div><div>Subsequently, verification is done with other tests. Finally, we analyze the effect of interface properties on the mechanical performance of CNC-based materials including, bending of a CNC bundle, tensile load and fracture in bioinspired structure of CNCs such as staggered brick-and-mortar and Bouligand structures of interest.</div></div>

<div>Synthetic Aperture Radar (SAR) is a technique to synthesize a large antenna array using the motion of a small antenna. When it comes to remote sensing, mapping, and change detection, SAR has been shown to be a good candidate by its ability to penetrate moisture and vegetation, and the avilibility of phase information for precise interferometric measurements [1] [13].</div><div><br></div><div><div>This study was motivated by the fact that satellite and high-altitude SAR has limited data availability in terms of temporal resolution and the cost of every measurement. It is believed that SAR systems mounted on smaller UAV or ground vehicles could provide a much better coverage of the target in time, and in dierent geometry.</div></div><div><br></div><div><div>We proposed a L-band SAR system based on Software-Defined Radio to be mounted on automotive platform. Novel motion estimation and compensation, as well as autofocusing techniques were developed to aid the SAR signal processing under much more demanding environment - the instability of radar platforms. It is expected this research development could bring down the cost of SAR being used as a remote sensing solution, and allow SAR system to be mounted on much smaller platforms by overcoming the instability of the track using novel signal processing methods, and eventually making SAR measurement available in places and times that was previously impossible.</div></div>

Buscar texto completoResumen
<p>A large number of crosswalks are
indicated by pavement markings and signs but are not signal-controlled. In this study, such a location is called
“semi-controlled”. In locations where
such a crosswalk has moderate amounts of pedestrian and vehicle traffic,
pedestrians and motorists often engage in a non-verbal “negotiation”, to
determine who should proceed first. </p>
<p> </p>
<p>In this study, 3400
pedestrian-motorist non-verbal interactions at such semi-controlled crosswalks
were recorded by video. The crosswalk locations observed during the study
underwent a conversion from one-way operation in Spring 2017 to two-way
operation in Spring 2018. This offered a
rare opportunity to collect and analyze data for the same location under two
conditions.</p>
<p> </p>
<p>This research explored factors
that could be associated with pedestrian crossing behavior and motorist <i>likelihood of decelerating</i>. A mixed
effects logit model and binary logistic regression were utilized to identify
factors that influence the likelihood of pedestrian crossing under specific
conditions. The complementary motorist
models used generalized ordered logistic regression to identify factors that
impact a driver’s <i>likelihood of
decelerating</i>, which was found to be a more useful factor than <i>likelihood of yielding to pedestrian</i>.
The data showed that 56.5% of drivers slowed down or stopped for pedestrians on
the one-way street. This value rose to
63.9% on the same street after it had been converted to 2-way operation. Moreover,
two-way operation eliminated the effects of the presence of other vehicles on
driver behavior.</p>
<p> </p>
<p>Also investigated were factors
that could influence how long a pedestrian is likely to wait at such
semi-controlled crosswalks. Two types of models were proposed to correlate
pedestrian waiting time with various covariates. First, survival models were
developed to analyze pedestrian wait time based on the first-event
analysis. Second, multi-state Markov models were introduced to correlate the
dynamic process between recurrent events. Combining the first-event and
recurrent events analyses addressed the drawbacks of both methods. Findings
from the before-and-after study can contribute to developing operational and
control strategies to improve the level of service at such unsignalized
crosswalks.</p>
<p> </p>
<p>The results of this study can
contribute to policies and/or control strategies that will improve the
efficiency of semi-controlled and similar crosswalks. This type of crosswalk is common, so the
benefits of well-supported strategies could be substantial. </p>

Buscar texto completoResumen
<div>Pack rust or crevice corrosion is a type of localized corrosion. When a metal is in contact with a metal, or even non-metal, the metal starts to corrode, and rust starts to pack in between the surfaces. When signicant development of pack rust occurs, it can cause overstressing of bolts and rivets causing them to fail, and it can bend connecting plates and member elements thus reducing their buckling capacity. Thus it is important to mitigate the formation and growth of pack rust in bridges. This study was conducted to determine if pack rust occurs frequently and thereby may pose a problem in the state of Indiana. The study is divided into three primary tasks.The rst part of the study involves understanding the parameters involved in the initiation process of crevice corrosion and post-initiation crevice corrosion process. The second part of the study involves reviewing existing mitigation strategies and repair procedures used by state DOTs. The third part of the study involves identifying steel bridges with pack rust in Indiana. Analyses were performed on the data collected from Indiana bridges that have pack rust. This involved nding the components and members of bridges which are most aected by pack rust and nding parameters which in uence the formation of pack rust. Pack rust in the steel bridges were identied using the INDOT inspection reports available through BIAS system. The study revealed that good maintenance practices helped in reducing pack rust formation. The study identied locations on steel bridges which have a high probability towards pack rust formation. A mitigating strategy possessing qualities which can show promising results is identied.</div>

Buscar texto completoResumen
<p>In our daily use of the transportation system, we are faced
with several road construction work zones. These construction work zones change
how road users interact with the transportation system due to the changes that
occur in the system such as increased travel times, increased delay times and
vehicle stopped times. A microscopic traffic simulation was developed to depict
the changes that occur in the transportation system. The impacts of the changes
in the transportation system on the human travel behavior was investigated
using ordered probit and logit models using five independent variables; age,
gender, driving experience, annual mileage and percentage of non-work trips.
Finally, a business impact assessment framework was developed to assess the
impact of the road construction work zones on various businesses categories such
as grocery stores, pharmacy, liquor stores and fast foods. Traffic simulation
results showed that the introduction of work zones in the road network introduces
an increase in delay times, vehicle stopped times, and travel times. Also, the change in average travel times,
delay times and vehicle stopped times differed from road link to link. The
observed average changes saw an increase as high as 318 seconds per vehicle,
237 seconds per vehicle and 242 seconds per vehicle for travel time, delay time
and vehicle stopped time, respectively, for the morning peak period. An average increase as high as 1607 seconds
per vehicle, 258 seconds per vehicle and 265 seconds per vehicle was observed
for travel time, delay time and vehicle stopped time, respectively, for the
afternoon peak period. The statistical
model results indicated that, on a work trip, a high driving experience, high
annual mileage, and high percentage of non-work trips makes an individual more
likely to change their route. The
results also showed gender difference in route choice behavior. Concerning business impacts, businesses in
the work zone were impacted differently with grocery and pharmacy stores having
the highest and lowest total loss in revenue, respectively.</p>

Buscar texto completoResumen
<p>Failure along rock discontinuities can result in economic losses
as well as loss of life. It is essential to develop methods that monitor the
response of these discontinuities to shear loading to enable prediction of
failure. Laboratory experiments are performed to investigate geophysical
techniques to monitor shear failure of a pre-existing discontinuity to detect
signatures of impending failure. Previous studies have detected precursors to
shear failure in the form of maxima of transmitted waves across a discontinuity
under shear. However, those experiments focused on well-matched
discontinuities. However, in nature, rock discontinuities are not always
perfectly matched because the asperities may be weathered by chemical, physical
or mechanical processes. Further, the specific shear mechanism of mismatched
discontinuities is still poorly understood. In this thesis, the ability
to detect seismic precursors to shear failure for various discontinuity
conditions—well-matched (rough and saw-tooth), mismatched (rough), and
nonplanar (discontinuity profile with a half-cycle sine wave (HCS))—was
assessed. The investigation was carried out through a coupled geophysical and
mechanical experimental program that integrated detailed laboratory
observations at the micro- and meso-scales. Shear experiments on gypsum discontinuities were conducted
to observe changes in compressional (P) and shear (S) waves transmitted across
the discontinuity. Digital
Image Correlation (DIC) was used to quantify the vertical and horizontal
displacements along the discontinuity during shearing to relate the location
and magnitude of slip with the measured wave amplitudes. </p>
<p>Results from the experiments conducted on planar, well-matched rough
discontinuities (grit 36 sandpaper roughness) showed that seismic precursors to
failure took the form of peaks in the normalized transmitted amplitude prior to
the peak shear stress. Seismic wave transmission detected non-uniform
dilation and closure of the discontinuity at a normal stress of 1 MPa. The
results showed that large-scale roughness (presence of a HCS) could mask the
generation of precursors, as it can cause non-uniform closure/dilation along
the fracture plane at low normal stress.
</p>
<p>The experiments on idealized
saw-toothed gypsum discontinuities showed that seismic precursors to failure
appeared as maxima in the transmitted wave amplitude and conversely as minima
in the reflected amplitudes. Converted waves (S to P & P to S) were also
detected, and their amplitudes reached a maximum prior to shear failure. DIC
results showed that slip occurred first at the top of the specimen, where the
load was applied, and then progressed along the joint as the shear stress
increased. This process was consistent with the order of emergence of
precursors, i.e., precursors were first recorded near the top and later at the
center, and finally at the bottom of the specimen. </p>
<p>Direct shear
experiments conducted on specimens with a mismatched discontinuity did not show
any precursors (in the transmitted amplitude) to failure at low normal stresses
(2 MPa), while those precursors appeared at higher normal stresses (5 MPa). The
interplay between wave transmission, the degree of mismatch, and the
discontinuity’s micro-physical, -chemical and -mechanical properties was
assessed through: (1) 3D CT in-situ Xray scans to quantify the degree of
mismatch at various normal stresses; (2) micro-indentation testing, to measure
the micro-strength of the asperities; and (3) Scanning Electron Microscopy
(SEM) and Electron Xray Diffraction (EDX), to study the micro-structure and
chemical composition of the discontinuity. The X-ray results showed that
contact between asperities increased with normal stress, even when the
discontinuity was mismatched. The results indicated that: (1) at 2 MPa, the
void aperture was large, so significant shear displacement was needed to interlock
and damage the asperities; and (2) the micro-hardness of the asperities of the
mismatched discontinuity was larger than that of the well-matched discontinuity,
which points to inducing less damage for the same shear displacement. Both
mechanisms contribute to the need for larger shear displacements to the mismatched
discontinuity asperities to cause damage, which is consistent with the
inability to detect seismic precursors to failure. The experimental results
suggest that monitoring changes in transmitted wave amplitude across a
discontinuity is a promising method for predicting impending failure for well-matched
rock discontinuities. Precursor monitoring for mismatched rock discontinuities
seems only possible when there is sufficient contact between the two rock
surfaces, which occurs at large normal stresses. </p>

Buscar texto completoResumen
<p>In recent years, there have been a number of truck fires involving
bridges with concrete components. If the fire burns for a significant period of
time, the structural integrity of concrete components could be damaged due to fire.
Research-based guidance for evaluating the level of fire damage is currently unavailable
and would be beneficial for post-fire bridge inspectors. </p>
<p>This research project focused on evaluating the effects of
fire induced damage on concrete bridge deck elements. In order to achieve this
goal, a series of controlled heating experiments and material analysis were
conducted. Two concrete bridge deck specimens from the I-469 bridge over
Feighner Road were heated for different time durations (40 - 80 min.) following
the ISO-834 temperature-time curve. The deck specimens were cooled naturally
after the specific heating durations. The temperature profiles through the
depth of deck specimens were measured during heating and cooling. After testing,
concrete samples were taken from the deck specimens for material analysis. Different
types of material tests were conducted on samples taken from the undamaged and
damaged deck specimens. The material test results were used to evaluate the
effects of fire induced damage on the concrete microstructure, and to correlate
the microstructure degradation with the through-depth temperature profiles of
deck specimens. </p>
<p>From the experimental results, several critical parameters
that can affected by fire temperature and duration were discussed: (i) through-depth
temperature profiles of deck specimens, (ii) cracks on the exposed surface of
deck specimens, (iii) color changes of deck specimens, (iv) microstructure of heated
concrete samples, (v) content of calcium hydroxide in fire damaged concrete
samples at various depths. Based on the results from heating experiments and
observations from material analysis, recommendations and guidance for
evaluating concrete decks subjected to realistic fire scenarios are provided to
assist bridge inspectors.</p>

with historical flow and nutrient data in a two-stage calibration process. The calibrated parameters
were validated to accurately simulate the field condition and preserved in SWAT model for
effectiveness analysis of BMP implementations. </div><div><br></div><div>To evaluate the effectiveness of VFS as a BMP, four different scenarios of VFS implementations

Buscar texto completoResumen
<div>The Indiana Department of Transportation implements maximum soil fill covers to ensure the safe installation and operation of buried pipes. Historically, fill cover tables are provided by INDOT, but the methodology for calculating these covers is not well documented. The finite element method enables a comprehensive analysis of the soil-pipe system taking into account soil conditions, pipe type and geometry, and conditions on the pipe-soil interface. </div><div><br></div><div>This thesis discusses the calculation of maximum fill covers for corrugated and structural plate pipe-arches using the finite element software CANDE and compares the results with previous estimates provided by INDOT. The CANDE software uses the Finite Element Method, and the Load and Resistance Factored design based on a two-dimensional culvert installation in a soil-pipe model. The model is set up under plain strain conditions and is subjected to factored dead and live load, and provides an analysis of the structure based on safety measures against all factored failure modes associated with the structural material.</div><div><br></div><div>Significant issues were encountered when calculating the maximum fill covers for pipe-arches in CANDE, including the inability of standard CANDE (Level 2 mesh) to model pipe-arches, lack of convergence for nonlinear analysis, and fill cover results higher than expected. To solve these issues, the pipe-arches were modeled using Level 3 solution in CANDE. The CANDE analyses were run using small-deformation analysis after buckling was eliminated as a governing failure mode using parallel simulations in Abaqus. Numerical results were compared to analytical solutions following ASTM standards.</div><div><br></div><div>The results showed that CANDE and INDOT calculations differ significantly, with the CANDE results yielding higher fill covers than those provided in INDOT specifications. These differences are attributed to the assumed loading pattern at failure. While the CANDE results assume that the maximum fill cover height is defined by the failure of the pipe considering the radial pressure (Pv), the INDOT results are consistent with results obtained by limiting the bearing capacity of the soil around the corner radius (Pc).</div>

Texto completoResumen
Ecology, Engineering, and the Paradox of Management is the first book that addresses and reconciles what many take to be the core paradox facing environmental decision-makers and stakeholders: How do they restore the environment while at the same time provide ever more services reliably from that environment, including clean air, water and energy for more and more people? The book provides a conceptual framework, empirical case analyses, and organizational proposals to resolve the paradox, be it in the US, Europe, or elsewhere. Thus, Ecology, Engineering, and the Paradox of Management has multiple audiences. First are the key professions involved in the protection and improvement of ecosystems and in the provision and delivery of services from those ecosystems. These include ecologists (and other natural scientists such as conservation biologists, climatologists, forest scientists, and toxicologists), engineers (as well as hydrologists, environmental engineers, civil engineers, and line operators), modeling and gaming experts, managers, planners, and power, agriculture, and recreation communities. Another audience includes university researchers in ecology, conservation biology, engineering, the policy sciences, and resource management. Those interested in interdisciplinary approaches in these fields will also find the book especially helpful. Finally, those interested in the Everglades, the Columbia River Basin, San Francisco Bay-Delta, and the Green Heart of western Netherlands will find new insights here, as the book provides a detailed examination of the paradox in each of these cases.

AbstractForests mainly consist of long-lived trees or shrub species and are exposed to natural or human disturbances of different severities. They are essential components of the natural development of forest ecosystems, since by triggering natural selection and ecological succession processes, they can achieve the best status in terms of species composition and structure. Nevertheless, extreme events can cause serious economic or naturalistic losses and, in some cases, endanger specific forest ecosystems. Disturbance events that damage forests vary and include pests and diseases, fires, pollution, climate changes, overexploitation or inadequate silvicultural practices, excessive grazing and browsing, to name just a few. Health monitoring of forests is a necessary condition to provide useful information for the conservation of forest resources, as well as to support forest management practices aimed at increasing the resilience of forests and their adaptation capacity. Through ground surveys, the Italian national forest inventory INFC has classified the health condition of Italian forests and produced the estimates presented in the chapter. These concern the distribution of the Forest area by pathologies and damage presence, severity and cause. Estimates of the Forest area affected by defoliation, divided by defoliation class and localization of defoliation, are also presented.

One of the fastest growing areas in the world is the Asia-Pacific region. With anticipated acceleration in motorization and potentially-damaging unplanned urban sprawl, the region will be threatened by problems of traffic congestion, pollution and road hazards. Several countries in the region have taken a variety of proactive measures to ensure that the urban transportation systems are designed and operated in a smart, sustainable and safe manner. This chapter identifies the policies and practices in South Korea, Japan, China, Taiwan, Singapore and Australia, and seeks to draw lessons from these on how transportation schemes can be implemented elsewhere in Asia.

Transportation has the greatest importance in logistics. The main focus for the carriers is the cost of transportation. Transportation of hazardous materials (hazmat) is a special kind of transportation due to freight transported. Causalities due to the accidents caused by vehicles that are carrying hazardous materials will be intolerable. For hazmat transportation, in addition to transport costs, risk of transporting hazmat also has to be considered. Many researchers studied on hazmat transportation problems in order to propose optimal solutions with respect to cost, risk, emergency response, facility location etc. In this study, a literature survey of articles about hazmat transportation was prepared. The articles published in refereed journal from 1973 to 2014 were taken into consideration. The articles were also classified according to their main focuses and hazmat type carried.

Additive manufacturing (AM) is also referred to as 3D printing, rapid prototyping, solid freeform fabrication, rapid manufacturing, desktop manufacturing, direct digital manufacturing, layered manufacturing, generative manufacturing, layered manufacturing, solid free-form fabrication, rapid prototype, tool-less model making, etc. It is emerging as an important manufacturing technology. It is the process of building up of layer-by-layer by depositing a material to make a component using the digital 3D model data. The main advantages of AM are mass customization, minimisation of waste, freedom of designing complex structures, and ability to print large structures. AM is broadly applicable to all classes of materials including metals, ceramics, polymers, composites, and biological systems. The AM methods used for producing complex geometrical shapes are classified based either on energy source (laser, electron beam) used or the material feed stock (powder feed, wire feed).

The increasing of global competition and the need for rapid response to market changes drive manufacturing enterprises to adopt new business models. This chapter examines the recent years of research developed in the field of coordination approaches to support distributed production systems. The papers discussed concern the period of 2004-2010 published in international ISI journals. The research articles are classified according to nine fields of research: operational research models; collaborative architecture; negotiation and bargaining models; capacity exchange; revenue sharing; chemical engineering; electronic approach; general review; case study. The analysis of the literature highlights that the articles are distributed uniformly over the years analyzed. The most fields investigated are the collaborative architecture and operational research models, while emerging fields are the chemical engineering and revenue sharing based approaches. The discussion underlines the limitation of the literature and suggests the directions for future research.

Chapter 2 focuses on the period of the Civil War and Reconstruction, when formerly enslaved persons, classified as “contrabands” and refugees, were placed as domestic workers in northern households. The involvement of the Bureau of Freedmen, Refugees, and Abandoned Lands (the Freedmen’s Bureau) in the placement of refugees as servants prefigured the federal government’s expanded role as a broker of immigrant labor in the decades that followed, yet proved controversial. Designed to reduce government expenditures on the relief of refugees in Washington, D.C., and elsewhere, the Freedmen’s Bureau’s financing of black servants’ migration was viewed with skepticism by detractors who claimed that it revived—under the thin veneer of “free” labor—a version of the slave trade. Due to insufficient federal funding, the reluctance of black refugees to relocate to uncertain job situations in the North, and constant questions about its efficacy, the Freedmen’s Bureau—after contracting thousands of women and children to service positions—was ultimately forced to disband this initiative.

Texto completoResumen
Smart transportation is a framework that leverages the power of Information and Communication Technology for acquisition, management, and mining of traffic-related data sources. This chapter categorizes them into probe people and vehicles based on Global Positioning Systems, mobile phone cellular networks, and Bluetooth, location-based social networks, and transit data with the focus on smart cards. For each data source, the operational mechanism of the technology for capturing the data is succinctly demonstrated. Secondly, as the most salient feature of this study, the transport-domain applications of each data source that have been conducted by the previous studies are reviewed and classified into the main groups. Possible research directions are provided for all types of data sources. Finally, authors briefly mention challenges and their corresponding solutions in smart transportation.

Texto completoResumen
International research has shown that in most countries, there are few women studying towards information technology (IT) careers (Galpin, 2002), and there is much research, particularly in the United States (U.S.), United Kingdom (UK) and Australia into why this is the case (Gürer & Camp, 2002). This article considers the situation in sub-Saharan Africa and focuses on women’s involvement in the generation and creation of information and communication technologies (ICTs) in sub-Saharan Africa, as opposed to ICT use in sub-Saharan Africa, which is considered elsewhere in this volume. There are a number of aspects to the generation and creation of ICTs: how women are involved in this process as IT professionals and how they are educated for these careers, as well how technology can be used appropriately within the specific conditions of sub-Saharan Africa. ICTs will be considered in the broadest sense of the word, covering all electronic technologies, from computers and networking to radio and television. Women’s participation is important: The World Summit on the Information Society (WSIS) Gender Caucus (www.genderwsis.org) has identified women’s involvement in the design and development of technology as well as technology management policy, as key principles for the information society. Marcelle (2001) emphasizes the necessity for African women to become involved in technological and scientific areas, including “computer science, software engineering, network design, network management and related disciplines” (Marcelle, 2001, para. 15) to create an information society appropriate for African women. The diversity of those involved in design leads to higher-quality and more appropriate technological solutions (Borg, 2002; Lazowska, 2002). Background Sub-Saharan Africa has a population of 641 million, young (almost half under 15) and rural (35% urban). Significant problems are undernourishment, poverty and HIV/AIDS (United Nations Development Programme (UNDP), 2004). All the countries in sub-Saharan Africa are classified as developing countries. Some countries are relatively wealthy, such as Mauritius, South Africa, and Nigeria, but have large wealth disparities within their populations. Women in sub-Saharan Africa are expected to focus on the home, they have less access to education and health, and their contribution to family and community is not valued (Huyer, 1997).

Texto completoResumen
Delamination between thin films is classified into two types: opening mode and sliding mode. Corresponding to each mode, there is the interface strength between thin films. This paper aims to evaluate interface strength between the sub-micron thin films for opening mode and sliding mode, respectively. We already developed the evaluation method of interface fracture toughness for opening mode on the basis of fracture mechanics concept elsewhere. Moreover, the evaluation method of sliding mode is proposed and the interface strength between thin films for an advanced LSI is evaluated as the fracture toughness by using both methods. In both modes, the stress singularity appears in the vicinity of the edge of interface and governs the delamination. The criterion of crack initiation for each mode is evaluated as the interface toughness. The fracture toughness at the edge of interface in sliding mode is lower than that in opening mode.

Texto completoResumen
In this study, ten pedestrian crossing spots located in Dohuk City suburban area were selected to make analysis and evaluation to the behavior of the people crossing the main streets, and walking on sidewalks according to their genders. Data was collected using double video cameras fixed on selected points to observe pedestrian movements along crossings and sidewalks, their interaction with drivers, and vehicles conflicting them. Data compiled was classified and presented to measure numbers of moving vehicles, people, vehicle gaps, space, pedestrian unit flow, speeds of both pedestrians and vehicles passing the crossing lines on suburban midblock. Data was presented using Dohuk City GIS up-to-date map taken from the city Municipality Directorate. Data analysis was implemented, and different empirical models were chosen to study the different interactions and effects of human, geometric, and vehicular traffic parameters on the behavior of pedestrians crossing, and walking on crosswalks and sidewalks respectively. Results show that in crosswalks, pedestrian flow with their speeds were polynomial in nature, while unit flow and speed relationships with density were linearly correlated. The relation between unit flow and their speed (for both male and female) on suburban sidewalks is Polynomial 2nd degree, and the optimum walking speed obtained is 1.16 and 1.0 m/sec for male and female respectively, with minimum walking speed for females are lower than male but the maximum walking speed is similar.

Marine autonomous systems, be they underwater or surface vehicles are growing in numbers, maturing as technologies used by civil, science and military operators, and are gaining new capabilities. It is possible to insure autonomous systems at a reasonable rate. The regulatory frameworks pertaining to their use vary from country to country, but the international law for armed marine autonomous systems is out of date and would benefit from revision and update. This paper is a light-touch review of typical uses and capabilities of systems, does not contain classified or commercial in confidence material, based on the author’s 25+ years of familiarity with marine autonomous systems as they have evolved from laboratory prototypes into routinely used platforms for science, survey and surveillance.

Texto completoResumen
There are 19 in-service civil research reactors in China nowadays, which are quite diverse on reactor type, usage, power levels, operation modes and safety features [1]. The common practice in nuclear energy advanced countries is to do safety classification and classified management of research reactors. In recent years, China has gradually refined and improved the related work. This paper summarizes the existing research reactor graded approach and safety management requirements included in certain regulations, guidelines and technical documents of IAEA, the United States, Japan and China, and specific practice and experience on operational level as well. And then the classification principles, classification elements, classification methods, safety management requirements and other aspects of the countries or government organizations mentioned above are compared from the view of research reactor safety classification. It comes to the conclusion: As far as China’s research reactor graded approach and safety management requirements are concerned, more work are needed. The relevant provisions of research reactor graded approach of IAEA are comprehensive, and have good reference value for China’s legislation system, but the classification method operability is not strong enough, and there are no detailed management and technical guides as the supplement to the graded approach. The relevant provisions of the research reactor graded approach of the United States and Japan are not systemic enough, but the classification methods are clear and operable, which are referable for China’s relevant practice on research reactor safety classification. After the Fukushima nuclear power plant accident, the classified management of the research reactors has achieved quite good results in comprehensive safety inspection of China’s civil research reactors. Finally, some suggestions in respect of the establishment and improvement of China’s research reactor safety classification guidelines and documents, standardization the use of graded approach, and application in the review and supervision of research reactor in China are put forward.

Texto completoResumen
The 5 Russian Arctic Seas have common features, but differ significantly from each other in the sea ice regime and navigation specifics. Navigation in the Arctic is a big challenge, especially during the winter season. However, it is necessary, due to limited natural resources elsewhere on Earth that may be easier for exploitation. Therefore sea ice is an important issue for future development. We foresee that the Arctic may become ice free in summer as a result of global warming and even light yachts will be able to pass through the Eastern Passage. There have been several such examples in the last years. But sea ice is an inherent feature of Arctic Seas in winter, it is permanently immanent for the Central Arctic Basin. That is why it is important to get appropriate knowledge about sea ice properties and operations in ice conditions. Four seas, the Kara, Laptev, East Siberian, and Chukchi have been examined in the book “Russian Arctic Seas. Navigation Condition and Accidents”, Marchenko, 2012 [1]. The book is devoted to the eastern sector of the Arctic, with a description of the seas and accidents caused by heavy ice conditions. The traditional physical-geographical characteristics, information about the navigation conditions and the main sea routes and reports on accidents that occurred in the 20th century have reviewed. An additional investigation has been performed for more recent accidents and for the Barents Sea. Considerable attention has been paid to problems associated with sea ice caused by the present development of the Arctic. Sea ice can significantly affect shipping, drilling, and the construction and operation of platforms and handling terminals. Sea ice is present in the main part of the east Arctic Sea most of the year. The Barents Sea, which is strongly influenced and warmed by the North Atlantic Current, has a natural environment that is dramatically different from those of the other Arctic seas. The main difficulties with the Barents Sea are produced by icing and storms and in the north icebergs. The ice jet is the most dangerous phenomenon in the main straits along the Northern Sea Route and in Chukchi Seas. The accidents in the Arctic Sea have been classified, described and connected with weather and ice conditions. Behaviour of the crew is taken into consideration. The following types of the ice-induced accidents are distinguished: forced drift, forced overwintering, shipwreck, and serious damage to the hull in which the crew, sometimes with the help of other crews, could still save the ship. The main reasons for shipwrecks and damages are hits of ice floes (often in rather calm ice conditions), ice nipping (compression) and drift. Such investigation is important for safety in the Arctic.

Texto completoResumen
Process plants are vulnerable to natural hazards and, in particular, to earthquakes. Nevertheless, the quantitative assessment of seismic risk of process plants is a complex task because available methodologies developed in the field of civil and nuclear engineering are not readily applicable to process plants, while technical standards and regulations do not establish any procedure for the overall seismic risk assessment of industrial process plants located in earthquake-prone areas. This paper details the results of a case study performing a seismic risk assessment of an Italian refinery having a 85,000 barrels per day production capacity, and a storage capacity of over 1,500,000 m3. The analysis has been carried out resorting to a novel quantitative methodology developed in the framework of a European Union research program (INDUSE 2 SAFETY). The method is able to systematically generate potential starting scenarios, deriving from simultaneous interactions of the earthquake with each separate equipment, and to account for propagation of effects between distinct equipment (i.e. Domino effects) keeping track of multiple simultaneous and possibly interacting chains of accidents. In the paper the methodology, already described elsewhere, is briefly resumed, and numerical results are presented showing relevant accident chains and expected economic loss, demonstrating the capabilities of the developed tool.

<p>Ground improvement has become one of the most effective tools of geotechnical engineering, being adopted for an always larger variety of civil engineering applications. To reduce the role of subjective choices of operators, the use of different techniques tends to be codified by specific guidelines. In the European Union there is an ongoing effort to standardize execution and design within codes continuously reviewed by designated committees. A widespread and systematic standardisation on the ground improvement as a mean to mitigate the effects of liquefaction on buildings and infrastructures is missing. The paper presents and overview of traditional and new ground improvement technologies suitable for this application. The methods are firstly classified by considering their effects on the ground (e.g. densification, stabilization, drainage, desaturation, etc.). Design principles are then outlined for new or pre-existing buildings and infrastructures, considering the ongoing review process of the design Eurocodes.</p>

Shape Memory Alloys (SMAs) are active metallic materials classified as “smart” or “intelligent” materials along with piezoelectric ceramic and polymers, electro-active plastics, electro-rheological and magneto-rheological fluids and others. SMAs show a multitude of different and dependent properties interesting for technological applications. These properties depend on the peculiar deformation mechanisms, accounting for the so-called shape memory effect. SMAs are nowadays used in quite different fields, like thermo-mechanical devices, anti-loosening systems, biomedical applications, mechanical damping systems, in some cases employed for large scale civil engineering structures. These multifunctional materials can be naturally considered as sensor-actuator elements demonstrating large possibilities for applications in high-tech smart systems. The use of SMAs in actuators offers an excellent technological opportunity to develop reliable, robust, simple and lightweight elements within structures or as stand-alone components that can represent an alternative to electro-magnetic actuators commonly used in several fields of industrial applications, such as automotive, appliances, consumer electronics and aerospace. NiTi-based SMAs demonstrated to have the best combination of properties, especially in terms of the amount of work output per material volume and the large amount of recoverable stress and strain. However, there are several limiting factors to a widespread diffusion of SMAs to technological fields. For instance, SMAs display a critical dependence of the shape-memory related properties, like transition temperatures, on their actual composition. For this reason, a great care in the production steps, mainly based on casting processes, is required. Another critical aspect, that is to be considered when dealing with SMAs, is the strong influence of their thermo-mechanical history on their properties. This may disclose interesting perspectives of application to smart devices in which different aspects of the shape memory phenomenology, like one and two way shape memory effect, pseudoelasticity, damping capacity, etc., are used. Last, but not least, one of the most debated aspects around NiTi alloys is microcleanliness. This concept is becoming increasingly important as the industrial market moves to smaller, lower profile devices with thinner structures. In this work a general overview about the peculiar behavior of NiTi alloys along with their main issues, the shape memory components under development, and the main efforts and directions for materials improvement will be presented and discussed. A bird’s-eye view on the future opportunities of NiTi-based shape memory actuators for industrial applications will also be given.
