Automatic path tracking using linear quadratic control theory

The authors conducted a study of automatic path tracking performance in the automated highway system (AHS) public trials that were carried out in Japan in 1996. A comparison was made of proportional-plus-derivative (PD) control and linear quadratic (LQ) control as two potential control systems. Because the PD control system lacked state feedback of yaw motion, the interference of yaw motion on lateral motion could not be eliminated. This made it impossible to achieve both satisfactory response and convergence. The LQ control system, on the other hand, had a larger number of state feedback coefficients, enabling lateral motion to be separated from yaw motion. This made it possible to set the response and convergence of lateral motion at will. Driving on an automated highway system is premised on the receipt of feedforward information from the road-side infrastructure. In this study, it was shown both theoretically and experimentally that road curvature can be estimated logically as a vehicle travels along even in the absence of feedforward information on curvature. Logical estimates are obtained with an algorithm in which curvature is treated as a state variable. It was also shown experimentally that an autonomous lane-tracking vehicle can even navigate road curves of unknown curvature by using a regulator configured around the method of estimating road curvature logically.

The crash involvement of unlicensed drivers in Queensland

Despite on-going improvements in traffic law enforcement practices and technology, unlicensed driving remains a serious road safety problem in Australia. Among a range of concerns, there is growing evidence linking unlicensed driving with a cluster of other high-risk factors, including drink driving, youthfulness and single-vehicle crashes. In order to explore this problem, an investigation was undertaken into the crash involvement of unlicensed drivers in Queensland during the period 1992-96. The analysis showed that unlicensed drivers and motorcycle riders are significantly over-represented in severe crashes compared with licensed drivers. In the absence of adequate exposure data, it is unclear whether this is primarily indicative of differences in the behaviour of unlicensed drivers or of under-reporting of minor crashes by this group. Nevertheless, the results suggest that unlicensed drivers are more likely to engage in higher risk behaviours than licensed drivers. Serious casualty crashes involving these drivers are more likely to involve alcohol and drugs, motorcycle use, exceeding the speed limit and excessive speed for the conditions, and to occur on the weekend and at night (ie. recreational times). The results also suggest that unlicensed drivers do not represent a uniform group. The drivers most at risk of being involved in a serious crash were those who did not possess an appropriate class of licence for the vehicle they were driving. These drivers were predominantly males riding motorcycles. Drivers who were disqualified or cancelled at the time of the crash had a similar level of risk to those who had never been licensed, while the sub-group with the lowest risk was those with expired licences. The results draw into question the common assumption that unlicensed drivers tend to drive in a relatively safe manner in order to avoid detection. The implications for driver management policy and research are discussed.
Polymorphisms of xenobiotic-metabolizing and transporter genes and the risk of gastric and colorectal cancer in an admixed population of Brazil.

Introduction Colorectal (CRC) and Gastric (GC) cancers are responsible for considerable morbidity and mortality worldwide. In the North region of Brazil, these neoplasms are among the three most incident and aggressive types of cancer, constituting a severe problem of public health. Single Nucleotide Polymorphisms (SNPs) of xenobiotic metabolism and transporter genes may play a role in individual response to exposure to some of the compounds implicated in the cancer susceptibility. However, few studies have demonstrated the role of polymorphisms of xenobiotic metabolism and transporter genes in the susceptibility to CRC or GC in admixed populations. In this context, the study of variation in the activation and detoxification processes of xenobiotics may help to clarify the development of either GC or CRC in substructured populations, providing new insights about predictive diagnostic criteria in oncological investigations. MethodsWe performed an association study using 31 SNPs in 15 xenobiotic metabolism and transporter genes. The study was carried out in 121 CRC and 95 GC cases and 140 control individuals from Belém, a city which comprises a population with high levels of miscegenation, located in the Brazilian Amazon. Samples were genotyped using the QuantStudio™12K Flex Real-Time PCR System. Due to the high level of genetic admixture in the studied population, we applied a panel of 61 Ancestry Informative Marker standardized by our research group in an earlier study. Statistical analyses were performed in SPSS v.20. 0 and Structure v.2. 3.4ResultsThe results revealed a significant association between the increased CRC or GC risk and polymorphisms of ABCG2 (rs2231142) and DPYD genes (rs17116806, rs1801159). ConclusionsOur data suggest that polymorphisms in xenobiotic-metabolizing and transporter genes may be relevant to the susceptibility to both CRC and GC.
Impacts of Driving Experience and In-Vehicle Traffic Safety Information on Traffic Stability Risk in Young Male Drivers: An Evaluation Incorporating Driver's Short-Term Memory

The simultaneous impacts of driving experience and use of in-vehicle traffic safety information on traffic safety was investigated in this study, focusing on the driving behavior of young male drivers. To evaluate this influence, the utility function of the information was first defined by incorporating the influence of driving experience based on the forgetting phenomenon in the short-term memory. By putting this utility function into a driving stability risk model which was built by an ordered response modeling approach based on drivers' speed choice, the level of traffic safety was measured. The estimated results show that driving experience is associated with better recall of the provided in-vehicle traffic safety information, showing that risk of driving could reduce by provision of the safety information. Data used for the analysis was collected through an on-site driving experiment using a probe vehicle, which was conducted at a signalized intersection approach with a limited traffic signal visibility on the national highway Route 2 in Hiroshima City, Japan, in 2006.
Energy and Mode Filtering in a Graphene Channel With Unevenly Spaced Barriers with a Smooth Profile

We simulate the transport and shot noise behavior of graphene armchair ribbons with a series of parallel, unevenly spaced potential barriers with a smooth profile (which could result from the electrostatic effect of negatively biased gates). We analyze the effect of Klein tunneling and resonant tunneling on the individual modes propagating through the graphene channel, showing that this structure can behave as a mode and an energy filter for the charges injected from the contacts. Moreover, we study the different transport regimes (ballistic, strong localized, and diffusive) that can take place inside the graphene ribbon and the effect on the shot noise behavior of the device
Determinants of construction labour productivity in Oman

Notwithstanding the technological developments, construction continues to be a labour-intensive industry, and hence labour productivity remains the industry's predominant determinant of performance. One of the primary challenges facing the construction industry in the Sultanate of Oman is low labour productivity. Therefore, the objective of this study is to identify, explore and rank the relative importance of the cardinal determinants of construction labour productivity in Oman. A statistically representative sample of contractors was thus invited to participate in a structured questionnaire survey comprising 33 productivity factors. Using the relative importance index technique, the findings distinguish the following factors as most significant: (1) errors and omission in design drawings; (2) changes to orders during execution; (3) delay in responding to requests for information; (4) lack of labour supervision; (5) clarity of project specifications; (6) coordination level amongst design disciplines; (7) working overtime; (8) rework; (9) inclement weather; and (10) physical fatigue. The outcomes not only fill a gap in knowledge of the critical determinants of labour productivity in the Sultanate, but may also be used by academics and industry practitioners to develop a deeper and wider perspective on the factors influencing the efficiency of the construction labour force.
Numerical simulation of diaphragm rupture

The results from computer simulations of the gas-dynamic processes that occur during and after the rupture of diaphragms within shock tubes and expansion tubes are presented. A two-dimensional and axisymmetric finite-volume code that solves the unsteady Euler equations for inviscid compressible flow, was used to perform the simulations. The flow domains were represented as unstructured meshes of triangular cells and solution-adaptive remeshing was used to focus computational effort in regions where the flow-field gradients were high. The ability of the code to produce accurate solutions to the Euler equations was verified by examining the following test cases: supersonic vortex flow between two arcs, an ideal shock tube, and supersonic flow over a cone. The ideal shock tube problem was studied in detail, in particular the shock speed. The computed shock speed was accurate when the initial pressure ratio was low. When the initial pressure ratio was high the ow was dificult to resolve because of the large density ratio at the contact surface where significant numerical diffusion occurred. However, solution- adaptive remeshing was used to control the error and reasonable estimates for the shock speed were obtained. The code was used to perform multi-dimensional simulations of the gradual opening of a primary diaphragm within a shock tube. The development of the flow, in particular the contact surface was examined and found to be strongly dependent on the initial pressure ratio across the diaphragm. For high initial pressure ratios across the diaphragm, previous experiments have shown that the measured shock speed can exceed the shock speed predicted by one- dimensional models. The shock speeds computed via the present multi-dimensional simulation were higher than those estimated by previous one-dimensional models and were closer to the experimental measurements. This indicates that multi- dimensional ow effects were partly responsible for the relatively high shock speeds measured in the experiments. The code also has the ability to simulate two-dimensional fluid-structure interac- tions. To achieve this the Euler equations are solved for a general moving frame of reference. Mesh management during a simulation is important. This includes the ability to automatically generate a new mesh when the current mesh becomes distorted (due to the motion of the structures) and the transfer of the solution from the old mesh to the new. The shock induced rupture of thin diaphragms was examined. Previous one dimen- sional models are awed because they do not simultaneously consider the diaphragm mass and allow the upstream gas to penetrate the diaphragm mass. Two multi- dimensional models which allow the upstream gas to penetrate are described. The first model assumes the diaphragm vaporises immediately after the arrival of the incident shock. The second model assumes the diaphragm shatters into a number of pieces which can be treated as rigid bodies. The results from both models are compared with experimental data.
Statistical analysis of lateral house connection failure mechanisms

Abstract The performance of lateral house connections can have a substantial impact on the overall level of service provided by sewer systems. However, knowledge on the failure probability of these components remains scarce. This paper analyses field data to determine failure rates. A distinction is made between different mechanisms that contribute to the overall failure probability of lateral house connections. Root causes that promote the occurrence of these failure mechanisms are derived from a literature review. Results of a trend analysis shows a time constant failure rate, which exceeds blockage rates reported for main sewers. Fat, oil, and grease deposits are the dominant failure mechanism for both a specific case study in Rotterdam and the Netherlands. Literature suggests misuse and the structural condition as main root causes for this failure mechanism. The sheer number of failures associated with lateral house connections suggests that these components should be taken into account in sewer asset management.
Water Quality Monitoring System Implemented With IoT

Monitoring the quality of water and its proper management is crucial for any industrial and economic application. The global shortage of water demands a sustainable solution to optimize its usage. The Internet of Things provides a robust and cost-effective solution for real-time monitoring of various parameters of water. The paper aims to implementan intelligent water quality monitoring system with the aid of IoT. The proposed system was successfully implemented to determine the turbidity, TDS, flow rate and the level of water for a given sample. The data obtained from the sensors are uploaded to the ThingSpeak dashboard for online monitoring purpose. Besides, an SMS alert is sent to the user whenever the turbidity and TDS values have crossed the threshold limit defined for good quality water.
Exploring Anti-FVIII Antibodies in Haemophilia A - Role in In Vitro Haemostasis and Clinical Disease

Haemophilia A (HA) is caused by defective synthesis of coagulation factor VIII(FVIII), which has serious effects on haemostasis; joints being the most common site of bleeding. The development of FVIII replacements has improved the situation for patients with haemophilia such that chronic arthropathy can be prevented, and life expectancy and the quality of life have increased. However, approximately 20-30% of patients suffering from severe HA develop neutralizing antibodies (inhibitors) against FVIII. Alternative treatment, using by-passing agents, is available for patients exhibiting inhibitors, although these can only be used for the short-term treatment of acute haemorrhage and as prophylaxis during surgery. Furthermore, the clinical response to by-passing products is unpredictable. Two of the studies included in this thesis evaluated the response to by-passing therapy in plasma from patients with HA. The variation in thrombin production within families was found to be significantly lower than the variation between families, indicating that a familial predisposition may influence thrombin formation in response to by-passing agents (Paper I). Moreover, FVIII clotting factors were found to potentiate the in vitro effect of by-passing agents on thrombin formation in plasma from patients with HA exhibiting inhibitors, indicating that further assessment of this treatment strategy in a clinical context is warranted (Paper II). Not all anti-FVIII antibodies have neutralizing capacity. In the studies presented in Papers III & V, non-neutralizing anti-FVIII antibodies(NNAs) were investigated in two different cohorts, using an enzyme-linked immunosorbent assay (ELISA). NNAs were detected in 18.9% of siblings with HA, and in 12.8% of unrelated HA subjects followed for four years. The antibody response was assayed using three different rFVIII products. The antibody response was found to be heterogeneous, to vary considerably between individuals (Papers III and V), and also over time (Paper V). None of the patients in the cohort with NNAs observed longitudinally developed inhibitors (Paper V). However, in one patient with moderate HA, the detection of Bethesda-negative anti-FVIII antibodies coincided with a change in bleeding phenotype four years prior to FVIII inhibitor development. This finding suggests that immunoassays may be a useful complement in evaluating the immune response to FVIII (Paper IV). The potential clinical impact of NNAs was evaluated in the long term study (Paper V), showing no association between age, F8 mutation, or the influence of immune system challenges on NNA development. Interestingly, patients with NNAs had significantly fewer bleeding episodes than NNA-negative patients (p=0.048), raising questions about the possibility of yet undefined types of anti-FVIII antibodies with protective or potentiating effects on FVIII.
Assessing the Productivity, Quality and Profitability of Orange Fleshed Sweet Potatoes Grown in Riverbank of the Tista Floodplain Agro-Ecological Zone of Bangladesh

Orange fleshed sweet potatoes (OFSP) are desirable for high productivity and profitability and their distribution to improve the nutrition of river bank inhabitants of Gaibandha and Rangpur districts of Bangladesh. In this context, a field trial was conducted in two riverbank-based farmers’ fields such as Saghata, Gaibandha, and Pirganj, Rangpur, particularly in the Active Tista Floodplain Agro-ecological Zone of Bangladesh. Four OFSP varieties were evaluated, i.e., G1: BARI SP-8; G2: BARI SP-12; G3: BARI SP-14; G4: BARI SP-15, along with one local cultivar as a control (Red skin with white flesh). Significant variations among the sweet potato genotypes were noted for a number of tuberous roots plant−1, length of root diameter of roots, tuberous root weight plant−1, root yield (fresh), root yield (dry), beta-carotene yield, as well as energy output. Over the locations, BARI SP-12 produced about 73% higher root yield (32.00 t ha−1) and it was like the BARI SP-8 (31.07 t ha−1), which produced about 68% higher yield in comparison with local cultivar (18.51 t ha−1). Across the location, BARI SP-8 performed better in root yield (31.89 t ha−1) in Gaibandha, 69% superior to local cultivar, whereas BARI SP-12 performed better in Rangpur (33.66 t ha−1), which was 86% greater than the local sweet potato cultivar. Considering the root dry yield production, BARI SP-8 produced the highest in the Gaibandha location after that Rangpur location. Further, BARI SP-14 had wider adaptability and stability over the year and location depended on the AMMI model. The beta carotene yield (Vitamin-A precursor) ranged 336–2957 kg ha−1 among the OFSP varieties, whereas the highest (2957 kg ha−1) carotene was recorded in BARI SP-14, similar to BARI SP-15 (2952 kg ha−1) but was much lower in BARI SP-8 and BARI SP-12. Moreover, BARI SP-8 and BARI SP-12 were also economically profitable in terms of gross margin (3233 and 3364 US$ ha−1, respectively), net return (3039 and 3170 US$ ha−1, respectively) and BCR (3.21 and 3.31, respectively, vs. 1.91) due to higher returns with a similar production cost of the local cultivar. The results suggested that BARI SP-8 is economically profitable in the riverbank areas of Gaibandha, and BARI SP-12 is suitable for the riverbank areas of Rangpur.
Automated design synthesis of structures using growth enhanced evolution

Engineering design is a complex problem on generating and evaluating a variety of options. In traditional methods, this typically involves evaluating up to a dozen different point designs. The limit on the process is the amount of time to generate, refine, and evaluate the various concepts. Using a computer helps to speed up the process, but human involvement still remains the weakest link. The natural extension of this process is to continually and rapid generate, refine, and evaluate concepts entirely automatically. Evolutionary Algorithms provide such a method, by emulating natural evolution. The computer maintains a population point design, each of which is represented by a gene string that is allowed to change (mutate) and combine with other genes (crossover). At each generation, every individual is modified then evaluated and the improved solutions proceed to the next generation. This thesis will extend the biological model by introducing a growth process to each individual. This is akin to the concept of a multi-cellular organism developing in the womb. An encoding for discrete truss structures is described that provides for such an extension. The truss grows from a few basic elements. After showing several examples demonstrating the growth process, the method is applied to a couple simple examples using evolutionary algorithms.
