Time-reversal and Interferometry with applications to forward modeling of wave propagation and a chapter on receiver functions

In exploration seismics and non-destructive evaluation, acoustic, elastic and electro-magnetic waves sensitive to inhomogeneities in the medium under investigation are used to probe its interior. Waves multiply scattered by the inhomogeneities carry significant information but, due to their non-linear relation with the inhomogeneities, are notoriously difficult to image or invert for subsurface structure. Recently, however, this paradigm may have been broken as it was shown that high-order multiply scattered acoustic waves can be time-reversed and focused onto their original source location through arbitrary, unknown, inhomogeneous media using a so-called time-reversal mirror: in a first step, the multiply scattered waves are recorded on an array of transducers partially surrounding the medium, in the second step the recorded wavefields are time-reversed and reemitted into the medium (i.e., the time-reversal mirror acts as a linear boundary condition on the medium injecting the time-reversed, multiply scattered wavefield). The multiply scattered waves retrace their paths through the medium and focus on the original source location. In another development the full waveform Green’s function between two (passive) receivers has been observed to emerge from crosscorrelation of multiply scattered coda waves. This process is called interferometry. The principal aim of this thesis is to explore the relation between time-reversal and interferometry and to apply the resulting insights to forward modeling of wave propagation in the broader context of inversion. A secondary aim is to see if the seismological receiver function method can be applied to a reflection setting in ways that are both dynamically and kinematically correct. These aims are achieved through: (1) Derivation of an integral representation for the time-reversed wavefield in arbitrary points of an inhomogeneous medium [first, for the acoustic case, based on the Kirchhoff-Helmholtz integral, then for the elastic case based on the Betti-Rayleigh reciprocity theorem].

An Investigation into Motivational Self-Systems of Turkish English Language Learners in Higher Education

Motivational self-systems have been researched in various educational settings including the English language teaching environment. However, motivational self-systems in the Turkish educational context still need to be investigated more due to the scarcity of studies in the local context, specifically with relation to the majors of the language learners. The current mixed-methods sequential explanatory study focuses on Turkish language learners' motivational self-systems and their correlation with the major of the learners. The quantitative data were collected from 118 participants in the Fall Term of 2019-2020 Academic Year based on convenience sampling at a language preparatory school of one of the state universities in Adana, Turkey through an adapted questionnaire. The qualitative data were gathered from 40 participants through reflective papers the participants were asked to keep at the beginning and end of the semester. The quantitative data were analyzed via SPSS 21 and the qualitative data were analyzed through thematic analysis. The findings indicated that there was no dominant L2MSS of Turkish language learners. The findings implied that the ideal L2 self of Turkish learners did not strongly correlate with their majors while their ought-to L2 self-had a strong correlation for some of the majors.
Ultra-wideband Frequency Selective Surface for Communication Applications

: A low-profile ultra-wideband (UWB) band-stop frequency selective surface (FSS) is designed for S-, C-, X- and Ku-bands communication applications. The FSS is constructed by using square and circular loop elements printed on the top and bottom sides of the RO3210 substrate. The FSS has been designed to reduce the electromagnetic interference (EMI) as well as to mitigate the harmful effects of electromagnetic radiation on the human body caused by different radio devices. The dimension and size of the UWB FSS have been reduced to 0.12 λ × 0.12 λ and 90%, respectively, as compared to the reported literature. The other advantages of the proposed FSS are that it is low profile, it has a simplified geometry and it ensures better angular and polarization stability of up to 85 ◦ . The –10 and –20 dB bandwidths of the proposed FSS are 146% (2.0–13.0 GHz) and 80% (4.87–11.42 GHz), respectively. Theoretical results have been obtained using ANSYS HFSS and verified through measured results.
QUANTIFYING COSTS DUE TO CHANGE

In construction changes to the quantity, quality, order and even the nature of the work seem unavoidable. Construction contracts usually provide for changes to the work by giving the engineer the necessary powers to effect changes. However, changes to the work should be effected in such a way that they do not change the basic contractual relationships of the parties at time of tender. The engineer is therefore also equipped with the power, and is in fact compelled (when necessary to keep the original contractual relationships intact) to change the rates of the contractor in the contract so that the scale remains balanced between the parties. This article discusses a technique that can assist both engineer and contractor to quantify this principle. (A)

Integral value engineering in design

Construction industry clients demand certainty in project cost, quality and time. The inability of traditionally composed design teams to consistently deliver this suggests that their expertise is sometimes inadequate. As clients become more dynamic in the next millennium, they are likely to demand greater certainty when construction projects are implemented to support frequent revisions in their short term function. By establishing a collaborative working framework it is proposed that supply chains can be better managed to identify and design out potential problems using integrated, collaborative design processes. This proposal is being investigated by the Integrated Collaborative Design (ICD) research project, a collaboration of AMEC Construction, Loughborough University and eleven supply organisations, supported by the EPSRC and DETR through the IDAC Link programme. Focusing on one component of the ICD project, this paper reviews existing, reactive, value engineering methods and by identifying their inadequacies establishes the need for an integrated approach. A value management context is described which integrates value engineering into continuous design processes. The paper discusses the opportunities for utilising supplier design expertise by modelling design process information flows. It also identifies potential cultural barriers to the use of design processes incorporating integral value engineering techniques and describes the linkage to other ICD components that are addressing these issues.
Dynamic Analysis of a Subsea Module During Splash-zone Transit

This thesis carries out a research on the dynamic performance of the template during the lowing operation through splash-zone. During the lifting operation, especially under harsh environment, the waves, winds as well as the currents will leave significant influences on the template. Hence, to study how the template performed under such environmental conditions is the main purpose of this thesis. A brief introduction to the marine operation industry as well as the lifting operation is presented first. During the installation, template is exposed to the magnificent dynamic loads from the environment. So during the lifting process, the forces acting on the template as well as the displacement of the template should be inspected and controlled. Thus, the wave description and an introduction to the different dynamic loads due to the wave movement are performed. In addition, the methodology and the theory background of SIMA program is also included in this thesis. After building up the model of the lifting system in SIMA, the static and dynamic analysis of the lifting operation is performed. The results of the static and dynamic analysis are all listed in the thesis as figures or tables. The finding of the studies shows that the template experiences a significant drift in the wave induced direction for all sea-states. Besides, the dynamic load of the lifting lines can be more than twice than the static load. This will lead to a huge challenge to the capacity of the lifting wires. Additionally, the vertical motion of the template is sufficient large during the lifting operation and may lead to potential risk. Overall, the environmental conditions have magnificent influences on the lifting structures. In particular, lifting operations must not take place once the significant wave height exceeds an up-limitation. On the meantime, the lifting action needs to be paused if the wave peak period is approaching a critical value.
Fundamental aspects of netted radar performance

Netted radar employs several spatially distributed transmitters and receivers for information retrieval. This system topology offers many advantages over traditional monostatic and bistatic systems which use a single transmitter and a single receiver. For example, it provides better utilization of reflected energy, more flexible system arrangement and enhanced information retrieval capability. Therefore, the netted radar system is of emerging interests among radar researchers. This work investigates several fundamental aspects that determine netted radar performance. This includes netted radar sensitivity, the netted radar ambiguity function and the netted radar ground plane effect. Mathematical models are developed to provide a mean to examine different aspects of netted radar performance. Software simulations examine netted radar performance over a range of parameter variations. Simulation results show that netted radar can offer better performance over traditional monnostatic and bistatic radar in many cases. Some elementary field trials have been conducted using a prototype netted radar system developed within the UCL radar group to examine aspects of netted radar performance in practice. The field trials are focused on netted radar range and sensitivity which are fundamental. The field trial results show that the theoretical benefits that netted radar can offer are generally realizable in practice.
LABORATORY EVALUATION OF THE ADDITION OF LIME TREATED SAND TO HOT-MIX ASPHALT

Moisture damage to hot-mix asphalt (HMA) is a major problem. Hydrated lime has been shown to be an effective additive for reducing moisture damage susceptibility of HMA. Among the currently used methods for addition of hydrated lime to HMA aggregate, the one most often used is to add the lime to the entire aggregate stream. A recent field trial has shown that it is feasible to add hydrated lime to only the sand fraction in amounts that are equivalent to the desired concentration on the total aggregate basis. This would allow set up of a central facility for adding lime to the sand fraction of an HMA aggregate. The lime/fine aggregate mixtures could then be transported to an HMA plant and mixed with the remaining aggregate fraction. This concept is investigated in the laboratory using three aggregate combinations, two methods of conditioning specimens for moisture susceptibility testing (AASHTO T283 and ASTM D4867), two methods of lime addition, and three lime concentration levels. A statistical analysis of the data indicates that the two methods of lime addition (lime to fine aggregate and lime to total aggregate) produce asphalt mixtures that are equivalent in reduced moisture damage susceptibility. Other statistical comparisons indicate that (a) the greatest reduction in moisture susceptibility of the mixtures studied occurred from increasing the lime content from 0.5 to 1.0% (total dry aggregate basis), with less effect resulting from a 1.0 to 1.5% increase; (b) both the AASHTO T283 and ASTM D4867 procedures can be used to evaluate moisture susceptibility, but it appears that the specific aggregate combination will determine which procedure is most severe for a particular mixture; and (c) the addition of lime in the form of a slurry was in most cases better than the addition of lime to a moist aggregate. On the basis of recent field trials and the data obtained in the investigation, it appears that the addition of lime to the fine aggregate fraction of HMA aggregates, followed by subsequent mixing with the remainder of the aggregate stream, is an innovative process that has the potential for reducing capital costs sometimes associated with lime addition, without compromising the beneficial effects of lime addition for reduced moisture damage susceptibility of HMA.
Design and Analysis of an Efficient and Reliable Mac Protocol for Vanets

The increase number of vehicles on roads and the immense number of fatal accidents they cause have driven the research and development of new generation technologies to help drivers travel more safely. One major cause of traffic accidents is that drivers cannot consistently respond to the changing road conditions appropriately. In fact, most accidents could be avoided if drivers could obtain and use relevant information of the traffic that is beyond their vision using wireless communications technology. Recently, the IEEE community adopted the IEEE 802.11p standard as a main technology for VANETs. To test the feasibility of this technology, most researchers use simulations to evaluate its new applications and protocols due to the prohibitive cost of implementing real VANET setup. Therefore, we first analyze VANET’s wireless channel analytically and by simulations to predict its most appropriate propagation model and the communication range that minimizes the impact of the hidden terminal problem. Second, we derive a new mobility model that takes into account the vehicle’s follow-on safety rule, to accurately derive the relationship between vehicle’s speed and network density. It is expected that broadcasting and multi hop communications will be dominant in VANETs safety applications and protocols. Therefore, a Network Topology p-Persistence (NTPP) scheme is proposed to alleviate the impact of the broadcast storm problem. NTPP is based on vehicles’ knowledge of their neighbors in their range and traffic parameters to reduce the channel contention, redundant re-broadcasts and message travel time and to increase the emergency message reception rate. We analyze the reliability of the IEEE 802.11p in VANETs safety and warning applications scope taking into consideration different factors. It is shown analytically and by extensive simulations that the current DSRC specifications may lead to undesirable performance under harsh vehicular environments. Therefore, a novel Distributed Multichannel and Mobility Aware Cluster-based MAC Protocol (DMCMAC) is proposed to alleviate the impact of the hidden terminal problem, increase the network capacity and reliability. Cluster heads in DMCMAC are elected and re-elected in a distributed manner according to their relative speed and distance from their cluster members. The high stability of DMCMAC results from its adaptability to drivers’ behavior on the road and its learning process to predict the future speed and position of all cluster members using the fuzzy logic inference system. The reliability of DMCMAC is analyzed and compared with other protocols. It is shown by simulations that DMCMAC has high stability, its performance exceeds other protocols and can achieve a timely and reliable delivery of emergency messages to their intended recipients which make it more suitable for VANETs. iv
Recombinant Production of E. coli NAD+-dependent DNA ligase as a Target for Antibacterial Drug Discovery

The increase in the frequency of drug resistance in bacterial infections has led to the research of new antibacterial agents targeting new mechanisms. Many of the functions of NAD+-dependent DNA ligase have made it a remarkable target for antibacterial drug discovery. Escherichia coli (E. coli) NAD+-dependent DNA ligase is presented as a potential target due to its unique substrate specificity compared to the ATP-dependent human DNA ligase. In this study, it was aimed to produce and purify the E. coli NAD + dependent DNA ligase enzyme, which is frequently used in antibacterial drug discovery. The E. coli DNA ligase gene sequence was cloned into pTOLT vector system. E. coli DNA ligase enzyme was purified after the production in E. coli BL21 (DE3) pLysE cells. It was clearly demonstrated by the activity test that the DNA ligase enzyme produced in this study can ligate the DNA fragments. As a result, it was revealed that the effect of candidate inhibitors can be studied simply on the enzyme. Research Article Article History Geliş Tarihi : 21.02. 2021 Kabul Tarihi : 20.04. 2021
Reducing changeover times in a web offset packaging environment

The printing industry has been experiencing steadily rising costs and declining profits, at times leading to the closing down, consolidation, or restructuring of printing companies. Lean Manufacturing is an effective tool that has helped several printing companies to overcome these rising costs by reducing the cost of production and by improving productivity (Cooper, 2007). This research identified methods to reduce setup times, leading to savings of close to $60,000 annually on one press. The average setup time was reduced by 60%, from over two hours to less than one hour. The changes implemented on one press could be standardized on the other two similar presses in the offset department to provide annual savings of over $200,000. The researcher worked with a packaging company for a period of six months, during which time he worked on improving the changeover time on one of the Stevens web offset presses. The method of study employed was called Action Research, which involved direct interaction with employees of the organization. The researcher used Process Cycle Efficiency (PCE) as a parameter of success, which is measure of the value added time. This research demonstrates that a Single Minute Exchange of Die (SMED) event can be used successfully in reducing setup times on a Stevens web offset press.
Providing Speed Advice to Vehicles Approaching an Intersection: Evaluation and Lessons Learned

In this paper an Optimized Dynamic Speed Advise (ODYSA) system is evaluated. This system was developed by DTV Consultants and recently (2010) implemented in the Netherlands in the province Zuid-Holland. ODYSA is designed to minimize, or at least reduce, the number of times the main stream traffic flow is forced to stop due to the presence of traffic lights at intersections. It does so combining traditional signal coordination and the provision of speed advises to vehicles. This system is relatively new in the Netherlands and there are plans to extend its use. The results from the evaluation in terms of fluidity of traffic are positive and promising but, as will be discussed in this paper, some difficult and major issues regarding fine-tuning of the speed advises and the Human Factors interaction with the system should be addressed first.
Modeling the practical performance of switched- capacitor converters and a method for automating state-space model generation

A new modeling technique and a method for automating the modeling process are introduced for analyzing complex switched-capacitor (SC) converters. The model uses conventional circuit analysis methods to derive state-space models of each switching state. Steady-state performance is derived and expressed as an equivalent resistance. Whereas previous techniques have provided either the detailed performance of a simple SC converter or the limiting performance of a complex SC converter, this new model is flexible enough to provide detailed performance for any practical converter. Nonuniform component choices, asymmetric duty cycles, and other deviations from an ideal converter can be readily included. Dynamics can also be analyzed. Iterative methods of design based on this model would require the formulation of many equations, which is time consuming if done manually. Therefore, an algorithm is introduced to automatically generate the equations required for this state-space based modeling. The state equations are generated algorithmically given a standard node incidence matrix generated from a user-defined netlist. The algorithm enables a designer to quickly iterate SC converter design solutions based on its predicted performance. The model and algorithm have been validated through simulation techniques and experimental data collected from laboratory
