Abstract:
Results are presented for undrained direct simple shear tests on a Beaufort Sea cohesive soil. Monotonic and one-way cyclic loading response characteristics are identified for a number of loading scenarios. The critical level of repeated loadings (CLRL) is determined for two overconsolidation ratios from tests having 30 000 cycles of loading. Postcyclic strength tests indicate that one-way cyclic loadings not causing failure have a strain-hardening effect on the material. High strain-rate testing is found to increase soil strength by as much as 40% compared with typical testing strain rates. Key words : strength, cyclic testing, clay, simple shear, strain rate.

Abstract:
The reservoir landslide in the Three Gorges Reservoir Area (TGRA) often suffers from local cyclic loading scenarios produced by surge waves, groundwater level fluctuation, traffic loading, and seismic activity. However, the effects of local cyclic loading on the shear resistance of the shear-zone of the reservoir landslide are poorly understood. This study experimentally investigates the effects of local cyclic loading on the shear strength and the deformation of shear-zone material using cyclic direct shear tests. A series of cyclic direct shear tests are performed with different normal stresses, cyclic periods, and numbers of cycles. The experimental results indicate that: (1) Compared with monotonic loading, local cyclic loading can significantly decrease the shear stress of shear-zone soil. (2) Shear-zone soil exhibits greater volumetric contraction under local cyclic loading conditions than that under monotonic loading. (3) Under different vertical stresses, the differentiation of shear deformation after 40 cycles of loading was slight and virtually insignificant. The research results reveal the weakening law of the mechanical strength of shear-zone soil under local cyclic loading, which provides a foundation for investigating the mechanism of the reservoir landslide under the fluctuation of water levels.

Abstract:
A three-dimensional penny-shaped crack under combined tensile and shear loadings is analyzed. The assumptions of Dugdale are applied to estimate the effects of plasticity around the edge of the crack. The solution for mode I tensile loading is well established within the context of the Dugdale assumptions, and for the case of shear loading, approximate results are derived for the yield ring width and crack sliding displacements, with the assumptions similar in form to the mode I case. By superposing the results of the tensile and shear loading, the solutions for a penny-shaped Dugdale crack under mixed mode static loading and modified for the analysis of fatigue crack growth. Based on the mixed mode Dugdale model and the accumulated plastic displacement criterion for crack growth, a fatigue crack growth equation with four-power effective stress intensity factor dependence is developed for a penny-shaped crack under conditions of mixed mode loading and small-scale yielding.

Abstract:
The aim of this study was to investigate the dynamic shear failure behavior of RC beams under rapid loading through an experimental study and also to set up a strut-and-tie model with loading rate effect to predict the dynamic shear resistance of RC beams. Thus, rapid loading test with 24 RC beams with a shear span-to-deep ratio of 1.9 was performed, in which shear reinforcement ratio and loading rate were variable. All of the RC beams exhibited shear compression failure. Although the shear resistance increases with increasing loading rate, the influence of loading rate on the shear resistance clearly depends on shear reinforcement ratio. The strut-and-tie model with loading rate effect was finally developed, in which the thickness of the compression strut was formulated to be increased with an increase in loading rate. The developed strut-and-tie model was good agreement with the experimental results.

Abstract:
Some results of 3D finite element analyses of the all fracture modes (AFM) specimen on mixed-mode II and III fracture are presented in this paper. The computational fracture analysis is based on the calculation of separated strain energy release rates (SERRs) along the crack front by the modified virtual crack closure integral (MVCCI)-method and the commercially available FE-code ANSYS. Calculation results show that under pure in-plane shear loading (mode II), not only the mode II, but also the mode III loading conditions, are generated owing to the Poission’s ratio effects. Similarly, under pure out-of-plane shear loading (mode III), besides the mode III, the mode II loading conditions are induced due to the global deformation. Nevertheless, once in-plane and out-of-plane shear loadings are superimposed, the fracture behavior appears more complex. Further discussion is given associate with some previous study.

Abstract:
In this paper, shear displacement properties of rock fractures were studied, and the energy evolution process was analyzed before sliding instability under complex shear loading paths. The artificial prefabrication method was used to simulate the natural rock fractures, which are difficult to obtain in the natural environment. The prepeak tiered cyclic loading tests under constant normal loading were performed on six rock specimens with fractures by rock direct shear apparatus (RDS-200). To obtain the stress difference of adjacent cycles, the direct shear test was conducted on the other six rock specimens with fractures before the prepeak tiered cyclic shear loading test. The variation trend of residual shear displacement (RSD) and the similarity of loading and unloading curves before slip instability were obtained by analyses of prepeak tiered cyclic shear loading test data. Energy evolution laws of rock fractures were analyzed with the consideration of the hysteresis characteristics, according to the hysteresis effect of shear displacement behind shear stress. This paper provides guidance for the study on shear instability of rock fractures under complex loading paths.

The aim of this study was to investigate the dynamic shear failure behavior of RC beams under rapid loading through an experimental study. Thus, rapid loading test for 48 RC beams was performed, in which shear span-to-depth ratio, shear reinforcement ratio and loading rate were variable. The RC beams exhibited diagonal tension failure, shear compression failure and flexural failure depending mainly on the shear span-to-depth ratio and the shear reinforcement ratio. The influence of loading rate on the maximum resistance is more significant for the RC beams failed in shear than for those failed in flexure.

Abstract:
Em virtude da presença cada vez mais frequente de solicitações cíclicas nas estruturas de engenharia e do aprimoramento da análise de projetos, os ensaios em solos sob carregamentos cíclicos tiveram seu interesse renovado nos últimos anos. Os ensaios de laboratório são realizados de forma que simulem, da melhor maneira possível, as condições observadas em campo. Tais condições auxiliam na escolha dos ensaios a serem conduzidos para a determinação de parâmetros geotécnicos relevantes a cada situação observada em campo. Dentre os ensaios empregados na Engenharia Geotécnica, destaca-se o simple shear. Este ensaio é conhecido e utilizado para medir a resistência ao cisalhamento e a rigidez de solos. Este é o único ensaio de laboratório capaz de submeter uma amostra a condições de deformação plana sob volume constante e permitir a rotação das tensões principais. Tais condições são frequentemente representativas em diversas situações em campo como, por exemplo, o modo de cisalhamento adjacente ao fuste de uma estaca ou sob plataformas offshore com base gravitacional. Nesse contexto, um equipamento foi desenvolvido para a realização de ensaios do tipo simple shear. O aparato conta com uma câmara, na qual é aplicada pressão à amostra de solo. Diferenciando-se do equipamento comercial para tais ensaios, que emprega uma membrana com anéis metálicos, a amostra de solo neste equipamento é envolta por uma membrana de látex, o que possibilita a consolidação de forma isotrópica ou anisotrópica. Quanto ao carregamento, o equipamento desenvolvido permite que o carregamento seja realizado de forma monotônica ou clíclica. Quando do carregamento cíclico, este pode ainda ser realizado de forma a se manter a tensão controlada ou a deformação. Foram conduzidos ensaios de calibração e validação do equipamento empregando-se uma areia fina de granulometria uniforme cujas propriedades são amplamente conhecidas através de outros ensaios. Os resultados obtidos foram então comparados com estudos no mesmo material em equipamentos triaxiais, cisalhamento direto e outro simple shear. Os resultados mostraram-se satisfatórios, validando o equipamento desenvolvido.<br>In view of the ever more frequent presence of the cyclic solicitations on Engineering structures and the enhancement of design analysis, the soil testing under cyclic loading conditions had its interest renewed in the last years. The laboratory tests are conduced in a way that simulates, in the best way possible, the observed field conditions. Said conditions aid on the choice of the tests to be conducted in order to determinate the relevant geomechanics parameters.to each situation observed on the field. Among the employed tests in Geotechnical Engineering, it is highlighted the simple shear. This test is known and used to measure the shear strength and soil righty. This is the only laboratory test capable of submitting the sample to plane strain conditions under constant volume and allows the main stress rotations. Said conditions are frequently representative in many field situations, such as, the adjacent shear mechanism to the shaft of a pile or, under offshore platforms with gravitational base. In this context, a equipment was developed to perform simple shear tests. The apparatus has a chamber, in which it is applied confining pressure to the soil sample. Contrasting from the commercial equipment for said tests, that uses a membrane with metallic rings, in this equipment the soil sample is involved by a latex membrane, allowing the consolidation being carried out isotropically or anisotropically. The loading on this equipment can be conduced on monotonic or cyclic conditions. The cyclic loading can even be conduced by controlling the deformation or the stress. Calibration and validation testes where conduced on the equipment using a fine sand of uniform granulometry which properties are largely known through other tests. The obtained results where then compared to other tests carried out on the same material in triaxial tests, direct shear and other simple shear, The results obtained were considered satisfactory, validating the developed equipment.

Abstract:
An experimental research program comprising constant-volume direct simple shear (DSS) tests was conducted to study the monotonic, cyclic shear and post cyclic consolidation response of natural silts. Relatively undisturbed samples of silt which were obtained from three different locations in the Lower Mainland area of British Columbia were used for this purpose. Plasticity indices of the natural silt samples which were considered for the study were 5, 7, and 34. Monotonic shear response of the natural silt was studied with the constant volume DSS test results that were conducted with different vertical effective stresses and different overconsolidation ratios (OCRs). Stress-strain response of normally consolidated silt at different consolidation stresses were found to be stress-history-normalizable where as higher OCR and higher plasticity resulted greater shear strength. Normally consolidated silt specimen, despite of their difference plasticity, exhibit gradual strain accumulation without abrupt loss of shear stiffness during cyclic loading with different cyclic stress ratios (CSRs) at different consolidation stress levels. The potential and rate of strain accumulation and development of excess pore-water pressure (Δu) were noted to be increased with higher CSRs at all tested consolidation stress levels. The cyclic shear resistances of silt, derived from cyclic direct simple shear (CDSS) tests, were not sensitive to the tested range of different consolidation stress levels, whereas higher plasticity resulted greater cyclic shear resistance. Relative undisturbed specimens exhibit comparatively higher cyclic shear resistance than the reconstituted specimens despite of comparatively denser particle arrangement in reconstituted specimens. However, during the constant-volume monotonic DSS tests, relative undisturbed specimens exhibit comparatively lesser shear resistance than the reconstituted specimens implying that soil fabric / microstructure plays a significant role in governing the shear loading response of silt. The examination of consolidation responses of silt specimens that were initially normally consolidated and subjected to constant-volume CDSS loading revealed that the post cyclic consolidation volumetric strain increases with the maximum cyclic pore-water pressure ratio developed during constant volume CDSS loading for all tested silt specimens with different plasticity.<br>Applied Science, Faculty of<br>Civil Engineering, Department of<br>Graduate

Abstract:
The cyclic shear response of low-plastic Fraser River silt was investigated using constant-volume direct simple shear testing. Silt specimens, initially consolidated to stress levels at or above the preconsolidation stress, displayed cyclic mobility type strain development during cyclic loading. Liquefaction in the form of strain softening accompanied by loss of shear strength did not manifest regardless of the applied cyclic stress ratio (CSR), or the level of induced excess pore water pressure (Δu). Cyclic mobility type stress-strain behaviour was observed in spite of the initial static shear stress bias. The potential for excess pore water pressure generation and associated shear strain development during cyclic loading was observed to increase with increasing level of initial static shear. Tests on specimens of undisturbed field samples and specimens reconstituted using the same silt material showed that undisturbed silt, despite having a looser density under identical consolidation stress conditions, exhibited more dilative response and larger shear resistance compared to those displayed by reconstituted specimens. In addition to consolidation stress conditions and resulting void ratios, it appears that other naturally inherited parameters such as soil fabric and aging effects would influence the shear response of natural silt. Studies were also conducted to examine the post-cyclic reconsolidation response of low-plastic silt using specimens of undisturbed and reconstituted Fraser River silt and reconstituted quartz powder initially subjected to constant volume cyclic loading at different CSR values and then reconsolidated to their initial effective stresses. The volumetric strains during post-cyclic reconsolidation (εv-ps) were noted to increase with the maximum Δu and maximum cyclic shear strain experienced during cyclic loading. The values of εv-ps and maximum excess cyclic pore water pressure ratio (ru max) were observed to form a coherent relationship regardless of overconsolidation effects, particle fabric, and initial void ratio of the soil. The specimens with high ru-max suffered significantly higher post-cyclic reconsolidation strains. The observed εv-ps versus ru-max relationship, when combined with the observed dependence of ru on CSR and number of load cycles, seems to provide a reasonable approach to estimate post-cyclic reconsolidation strains of low-plastic silt.

Abstract:
Bioengineering<br>M.S.<br>A meniscal tear is an injury that often occurs as a result of a varus or valgus rotation of the femur on the tibia coupled with axial rotation while the knee is partially flexed, thus creating preferential loading of the posterior horn and shear forces on the meniscus. Such injuries can be repaired surgically, either with standard suturing techniques or with commercially available all-inside meniscal repair devices, which are designed to make the repair surgery faster, easier, and potentially safer. Many prior biomechanical studies have loaded an excised, repaired meniscus in tension and found that the repaired meniscus performs similarly to an uninjured sample. However, it is more appropriate to apply shear forces to the tissue in order to simulate the mechanism of injury. To date, three prior studies have investigated the biomechanical properties of meniscal repairs in shear, all of which used isolated meniscal tissue samples. The present study used an in situ bovine model to investigate the strength of commercially available meniscal repair systems under a shear loading regime. Medial menisci were torn and subsequently repaired using one of three techniques: standard inside-out vertical mattress sutures, Depuy Mitek Omnispan, or Smith & Nephew Fast-Fix. A control group was left unrepaired. Samples were subjected to a battery of cyclic side loading to create shear forces within the knee. Statistical analysis (ANOVA) demonstrated no significant difference in the stiffness, shear force, or subsidence between groups. The conclusion that the repair techniques perform similarly is consistent with tensile and in situ testing. Pathological observations showed no significant differences between repair devices, but all repaired samples demonstrated less wear than unrepaired samples, indicating that the experimental model is an effective method for creating wear within the knee. This result indicates that the flexible all-inside devices are mechanically comparable to the more commonly performed conventional suturing techniques. It is concluded that the mechanical performance may not be the best indicator of success of the surgical repair, as long as the device is able to anatomically reduce the tear.<br>Temple University--Theses

Abstract:
Wide spaced reinforced masonry (WSRM) walls that contain vertical reinforced cores at horizontal spacing up to 2000mm are commonly used in high wind zones of Australia although their inplane shear resistance is not well understood. This thesis aims at providing better insight into the behaviour of WSRM walls subjected to inplane lateral loading through experimental and numerical investigations. The interactions between the unreinforced masonry (URM) panels and vertical reinforced cores are first determined using an elastic finite element analysis and the potential failure paths hypothesized. The hypotheses are then validated using a series of full-scale WSRM and Non-WSRM wall tests under monotonic and cyclic lateral loading by keeping the spacing between the vertical reinforced cores as the main design variable. Load-displacement response of these shear walls indicates that the current classification of the WSRM in AS3700 (2001) as those walls containing vertical reinforced grouted cores at 2000mm maximum spacing is appropriate. A finite element model (FEM) based on an explicit solution algorithm is developed for predicting the response of the masonry shear walls tested under static loading. The FEM has adopted macroscopic masonry failure criteria and flow rules, damaged plasticity model for grout and tension-only model for reinforcing bars reported in the literature, and predicted crack opening and post-peak load behaviour of the shear walls. By minimising the kinetic energy using appropriate time scaling, the FEM has provided reasonable and efficient prediction of load flow, crack patterns and load–displacement curves of the shear walls. The FEM is further validated using full-scale tests on WSRM walls of aspect ratios and pre-compression different to that tested before. The validated FEM is used to examine the appropriateness of the prescriptive design details for WSRM concrete masonry shear walls provided in AS3700 (2001) allowing for a large scatter in material properties. It is shown that the inplane shear capacity formula provided in AS3700 (2001) for squat WSRM shear walls is non-conservative.

AbstractUndrained dynamic-loading ring-shear apparatus (UDRA) is most appropriate to study landslide dynamics by simulating the entire process from the initial stage of stress before landslide occurrence and stress changes due to static, dynamic loading or pore pressure changes or other types of stress loading to the formation of a sliding surface and the steady-state shear resistance. This paper describes the mechanical structure of the apparatus of UDRA and provides a manual for readers to begin using the UDRA. Specific steps for testing procedures with video tutorials and data analysis are also provided in this paper. The paper concludes with a manual from start to finish for common ring shear tests: undrained monotonic shear stress control test, undrained cyclic loading test, undrained seismic loading test, and pore pressure control test.

Abstract:
AbstractThis study investigated the loading mechanism of SPFRC shear walls by conducting low-cycle repeated loading tests on two steel-polypropylene hybrid fiber reinforced concrete (SPFRC) shear walls and one reinforced concrete (RC) shear wall. Furthermore, this study analyzed the impact of fiber content and axial compression ratio on the failure mode, shear carrying capacity, ductility, and energy dissipation capacity of the shear walls. The test results show that hybrid fibers effectively restrain the development of cracks in shear walls, and improve the shear carrying capacity, deformation capacity, and energy dissipation capacity of the shear walls. Considering the contributions of hybrid fibers, horizontal and vertical distributed steel reinforcement, concrete diagonal struts, and concealed columns to shear carrying capacity, a calculation formula for the shear carrying capacity of SPFRC shear walls has been established based on the truss-diagonal brace mechanism. This formula has been validated using data from this study and relevant domestic literature. The average ratio of measured shear carrying capacity to calculated values is 1.01, with a standard deviation of 0.17, indicating a good agreement between them.

Abstract:
AbstractThis paper evaluates the shear strength of the steel stud connectors in the steel-UHPC lightweight composite bridge deck composed of the orthotropic steel deck with closed U-ribs. The interlaminar shear stress between the UHPC pavement and the steel plate of orthotropic steel deck in the new steel-UHPC lightweight composite bridge deck is computed using the finite element method, in which the influence of wheel loading conditions and overloaded vehicles are studied. Results show that the largest interlaminar transverse shear stress between UHPC pavement and steel plate is induced by the action of triple-axle loading. The interlaminar shear stress between the UHPC pavement and the steel plate will increase significantly under the action of the overloaded vehicles.

Abstract:
AbstractThe China Nansha District of Guangzhou City is located at the geographical center of the Pearl River estuary and the Greater Bay Area of Guangdong, Hong Kong, and Macau, is characterized by widely distributed saturated soft soil layers with poor engineering properties. Although many scholars have explored the influence of loading rate on the mechanical properties of soft soil, research on the variation of undrained shear strength of saturated soft soil under different shear strain rates is still limited. This article conducts an in-depth analysis of the mechanical behavior of saturated soft soil under different strain rates through true triaxial consolidated undrained shear tests. Under load, these layers exhibit a significant rate-dependent mechanical behavior. In order to reveal the influence of shear strain rate on the mechanical properties of highly saturated soft soils based on SPAX-2000 test system, a series of true triaxial consolidation undrained shear tests were carried out under different confining pressures and different strain rates, variation rules of undrained shear strength of saturated soft and the pore water pressure with strain rate were analyzed. The experimental results indicate that the strain-rate softening exists in saturated soft soil. Under the same consolidation conditions, the relative growth rate of shear strength is a monotonic increasing function of the logarithm of shear strain rate, and the smaller the intermediate principle stress, the more significant the effect of shear strain rate on shear strength. During the shearing process (The strain-rate range from 10–6/s to 10–2/s), the undrained shear strength of saturated soft soil increases with the growth of shear strain rate, following an exponential variation pattern. In the early stages of loading, the increase in pore water pressure and the maximum pore water pressure are significantly affected by the strain rate. Throughout the testing process, the variation of pore water pressure exhibits some fluctuation and hysteresis. Different from strongly structured clay, the strength of saturated soft soil undergoes a progressive change with the shear strain rate, without showing a distinct critical rate of transition.

Abstract:
AbstractThe effective application of lightweight stay-in-place concrete forms for casting shear walls subjected to wind and seismic loading is of particular concern to practitioners. Insufficient technical data available for new kinds of wall systems, such as Polyvinyl Chloride (PVC) form walls, hinder their implementation in construction practice. To that end, an effective experimental and numerical campaign was launched at Western Sydney University to investigate the structural performance of PVC form walls when subjected to in-plane shear loading. A set of push-out specimens was designated to conduct monotonic in-plane shear tests until failure. All failure phenomena, capping strengths, and ductility capacities were monitored. Test results indicated that the embedded PVC latticed webs could efficiently protect the concrete web from sudden crushing and improve ductility capacity and failure pattern of the specimens. Nonlinear finite element analysis on test specimens was also conducted and good correlation with experiment results was achieved.

Abstract:
AbstractIndia depends heavily on coal-based thermal power plants for its energy requirements, with as much as 75% of all installed power production capacity sourced from coal-based plants. Although the country is gradually moving towards non-conventional and renewable energy sources, still the dependency on coal-based energy is significant to date. Some recent studies have indicated that by 2030, the country will be in need of more than 1340 MT coal for power generation annually. The average ash production is 33% of coal consumed, which in turn implies that nearly 437 MT of annual ash production. To reduce this disposal problem and the construction cost of engineering structures, pond ash is nowadays encouraged to be widely used as a geotechnical fill material in various infrastructure, in particular highway construction. However, there is significant research gap regarding understanding the behaviour of pond ash, particularly under repetitive cyclic loading, vehicle-induced vibratory loading, and earthquake-induced high-intensity and high-frequency transient loadings. The present study focuses on experimentally investigating the cyclic behaviour of pond ash samples under various confining pressures and strain levels and relative densities. The pond ash sample was collected from the nearby Parichha Thermal Power Plant located in Jhansi town in Uttar Pradesh, India. A series of element-level strain-controlled cyclic simple shear tests have been conducted for this purpose, apart from physical characteristic tests, compaction test, permeability tests, and direct shear tests on pond ash. The dynamic shear modulus was observed to be highly sensitive to the change in confining pressure, showing an increase of about 34% when the confining pressure was increased from 100 kPa to 200 kPa. For subjected to higher strain amplitude, the ash material showed softer behaviour with faster degradation in strength and stiffness and increased vulnerability for liquefaction related failure.

Abstract:
Results from recent and ongoing investigations of frictional sliding under dynamic loading conditions are discussed. The configuration analyzed consists of two identical elastic plates with an interface characterized by a rate- and state-dependent frictional law. The calculations are carried out within a framework where two constitutive relations are used: a volumetric constitutive relation between stress and strain and a surface constitutive relation that characterizes the frictional behavior of the interface. The simulations discussed predict a variety of sliding modes including a crack-like mode and several pulse-like modes as well as circumstances where the sliding tip speed can exceed the longitudinal wave speed.

Abstract:
This report presents results of an evaluation study on the applicability of current design procedures (based on p-y curves) to the analysis of large-diameter shafts socketed in rock, and the identification of enhanced moment transfer mechanisms not considered in current design methodologies. For this purpose simplified models, and possible three-dimensional (3D) finite-element method (FEM) models are studied to shed some light on the response of drilled shafts socketed in rock. A parametric study using p-y and considering a wide range of rock properties and rock-socket depths, different criteria to define the soil and rock p-y curves, different beam theories, and different interface frictional resistances are presented and compared with 3D FEM simulations. A new element is discussed to account for the shaft toe and underlain rock interaction, which could provide benefit to reduce shear demands when the socket is shallow.

Abstract:
There were two main objectives of this research. The first objective was to verify SINTEFs' pipe/soil interaction model test results, on which the A.G.A. Level 2 and 3 soil models are based. The second objective was to quantify the amount of conservatives built into the model equations for stiffer clay soils (above 30 psf shear strength). The original testing (at SINTEF) was done in soft clay soils (30 psf), and extrapolations to stiffer soils were done very conservatively, because data was not available. To accomplish these two objectives, pipe-soil interaction model tests were conducted at Texas A and M University in clay soils of approximately 30, 75, and 150 psf shear strength. Twenty-seven monotonic loading tests, and fifty-seven cyclic tests concluding with pipe break-out were performed. This is roughly four times the amount of testing originally done on clay by SINTEF. The test parameters and results are summarized in Table 1-1 for the monotonic loading tests, and Table 1-2 for the cyclic (displacement controlled) loading tests.

Full text
Abstract:
After being in service for nearly 20 years, the Illinois Accelerated Pavement Tester (I-APT) was upgraded to provide enhanced capabilities for accelerated pavement testing. In addition to a new control system, the improvement included a newly designed load carriage, which allows for testing with a tandem half-axle, axle yaw, and shear loading (breaking and accelerating). The new I-APT design could be fitted with various tire configurations (e.g., single, dual, wide-base, and aircraft). In addition, a tandem axle can be used that has the ability to vary axle spacing between 37 and 68 in. and wander tracking up to 18 in. Loading at a yaw angle of up to 6 degrees will now be possible, simulating lateral force, along shear force simulating skidding on pavement, which requires torque variations. Other improvements include the following: i) replacing the original electrically activated winch with a hydraulic power system, which will minimize electrical noise interferences with sensor signals; ii) advanced computing system file management using LabView codes; and iii) a new control trailer to operate the device.
