An Efficient System for Early Diagnosis of Breast Cancer using Support Vector Machine

There are many lives lost every year due to cancer and among them; among the women breast cancer causes the most deaths. For the better prediction of breast cancer risks, numerous studies have been undertaken incorporating data mining techniques. 1.1 million Cases of breast cancer were reported in 2004. It has been seen over the years that, that the numbers increase with the increasing industrialization and urbanization. It was earlier observed that mostly affected countries with breast cancer were high income countries such as America but now a days it is also very serious issue in middle and low income countries like Africa, Latin America and Asia. The main objective of this paper is to create a model which can more efficiently and accurately categorize a cancer as malignant or benevolent based on interpretation of the numerical values of attributes of ultrasound images of breast cancer. In this paper various data mining algorithm used like SVM(Support Vector Machine) for prediction and compared it with various other algorithms such as CART, Logistic Regression, KNN for the best training and test accuracy. SVM algorithm gives the most accurate results among the rest algorithm.
Visioning the Bus System of the Future: Stakeholders’ Perspective

The European Bus System of the Future (2008–2013) was a project funded by the European Commission within the seventh Framework Program. The core of the project was to develop a new generation of bus systems to increase the attractiveness and improve the image of this transport mode. Seven European cities were selected to test the innovative measures described in this paper: Bremerhaven, Germany; Brunoy, France; Budapest, Hungary; Gothenburg, Sweden; Madrid, Spain; Rome; and Rouen, France. The results served as a basis to develop the transferability exercise, that is, the assessment of drivers and barriers that might endorse or hinder the transferability of the measures to other cities. The transferability exercise required a specific method to define what was transferable from the experience of the seven cities (the use cases) and “to which contexts,” according to the panel of stakeholders who took part in the transferability exercise. The paper describes how the method was applied and the outcomes of the transferability exercise, which simulated the transferability of the experience of the seven use cases to a cluster of target cities across Europe. The resulting key factors for transferring (or not) the innovations and for developing a new generation of buses far beyond Europe's borders are reported.
A fuzzy hybrid singularity avoidance for underwater vehicle-manipulator systems

Abstract This paper investigates the possibility of applying a hybrid control with a fuzzy approach for redundancy resolution to an autonomous underwater vehicle-manipulator system (UVMS). This algorithm generates a desired trajectory for the vehicle that takes into account two control objectives: the energy savings and the increase of system manipulability by a smooth actuation. The computer simulation results demonstrate the efficiency of this approach.
An adaptive energy efficient protocol in media access control

In this paper, we propose a novel pe-frame based TPC protocol, an Adaptive Energy efficient protocol in Media Access Control (AE-MAC), in ad-hoc networks using IEEE 802.11 at low PHY rate. To avoid interference, improve throughput, and save energy, AE-MAC adaptive looks for the optimal transmit power based on the network interference and data payload. Transmit Power Control (TPC) protocols is proposed to address the limited power supplies in ad-hoc networks. However,most of the previous work minimize the transmit power without considering both the energy wasted in collisions and energy used to overcome the interference from all the interfering nodes existing in the network. Previous experiments show that optimal transmit power for the maximum throughput and per frame minimum consumed energy exists and occurs when the power level is sufficient to avoid interference, and causes the least contention between nodes. AE-MAC is validate via simulations and is shown to outperform several existing TCP protocols.
Design of Topologies for Interpreting Assays on Digital Microfluidic Biochips

In the last decade, digital microfluidic biochips have emerged as a viable candidate for the automation and miniaturization of biochemistry; however, digital microfluidic designs in previous works typically suffer from two short-comings: 1. ) they are unable to respond to live feedback and errors; 2. ) they are application-specific, rather than programmable. In the early years of digital microfluidic research, the synthesis problems of scheduling, placement and routing were performed offline (before runtime) due to their algorithmic complexity, typically yielding application-specific devices that could perform only one type of biochemical reaction and could not respond to live feedback in a timely manner, due to the complexity of their algorithms. This dissertation offers topological solutions toward realizing digital microfluidic biochips that are both dynamic and programmable in nature. We begin by presenting interpretation, which is a form of dynamic synthesis. Instead of static compilation which generates a deterministic electrode activation sequence, interpretation acts like an operating system that manages resources as an assay is being executed, allowing for resources to be allocated and dispatched dynamically in response to live feedback from integrated sensors and video monitoring. We also present new language constructs necessary to incorporate control flow into digital microfluidic biochips (DMFBs). We then introduce virtual topologies, a virtual organization of electrodes into city streets and blocks, which help simplify dynamic synthesis flow algorithms; we show two new virtual topologies and describe scheduling, placement and routing algorithms to accompany them, yielding fast, reliable, dynamic, programmable DMFBs. Finally, we present a field-programmable, pin-constrained (FPPC), topology which, for the first time, offers a solution to reduce the cost of a DMFB while maintaining programmability. We include results which show our FPPC design to be the least expensive when compared to prior pin-constrained and direct addressing DMFBs, while offering unmatched flexibility next to its closest competitors in price. We conclude with the first detailed cost analysis and shed light on the relationship between PCB layer count, pin count and cost. Our results reveal that the minimization of pin-count, if not done carefully, can necessitate additional PCB layers and yield a more expensive DMFB.
Ethnomedicinal Study of Plants Used against Human Ailments in Aseko District, South East Ethiopia

Background Over exploitation of MPs to treat human ailments in highly populated regions caused by deforestation and agricultural expansion disappearing (MP) species diversity in the areas, MPs Hence, this study was aimed to document and analyze the plant-based ethnomedicinal knowledge of the people in order to preserve the existing indigenous knowledge. Methods Ethnobotanical data were collected using semi-structured interview, key informants interview, guided field observations, group discussions & market survey. Quantitative approaches were used to determine Informant Consensus Factor (ICF), pair wise comparison, preference ranking and Fidelity level (FL) values. Results A total of 96 medicinal plant species belonging to 89 genera and 66 botanical families were reported to treat human diseases in the Aseko District. Plant Families with the highest number of species were Lamiaceae and Solanaceae, followed by Fabaceae. About 44% of Medicinal Plants (MPs) preparations were reported to be obtained from leaves. Highest ICF values were recorded for gastrointestinal (0.76) & parasitic and febrile illnesses (0.74) indicating best agreement among informants’ knowledge on MPs used to treat aliments in these categories. The highest fidelity level values (100% FL) were recorded for Ocimum gratissimum L against febrile diseases, Rubus steudneri Schw against Asthma and Podocarpus falcatus against Intestinal Parasite) for each, showing conformity of knowledge on species of the best healing potential. Cordia africana was ranked first in a direct matrix ranking exercise of multipurpose Medicinal Plants. The output of preference ranking exercise indicated that Urtica simensis Steudel was the most preferred species to treat gastritis. Conclusion The study revealed that Aseko district is rich in MP diversity and associated indigenous knowledge. However, anthropogenic factors (over exploitation) coupled with acculturation threaten the sustainability of MPs in the study area. Promoting a complementary in-situ and ex-situ conservation approach in the District is highly recommendable for MP sustainability.
Variable Rate Technology and Cotton Yield Response in Texas

Variable Rate Technology (VRT) takes within-field variability into consideration and aims to match resource application to crop requirement. Even though Texas is the most important cotton producing state in the US, the rate of VRT adoption is very low here. Hence, analyzing the factors influencing the adoption and providing a regional estimate of the impact of VRT adoption on cotton yield is very important. This study used the 2009 Southern Cotton Precision Farming Survey to analyze the farm and farmer characteristics affecting the adoption of VRT among Texas cotton farmers and to empirically estimate the impact of adoption of VRT on cotton yield in Texas. A two-stage least square procedure with a logistic regression model in the first stage and a multiple linear regression model in the second stage was used to analyze the data. The study revealed that there are significant regional differences in adoption pattern within the state of Texas; and the farmers from the coastal region, where there is higher within-field variability, were more likely to adopt VRT compared to other regions. Younger farmers, farmers managing larger farms, and farmers who use computers for farming operations were more likely to adopt VRT. The results also showed that, on an average, the adoption of VRT does not lead to significant yield improvements for cotton in Texas. Since the impact of VRT adoption on yield is not significant, the source of economic advantage of VRT adoption in Texas may be the reduction of input cost.

Methods for automatic inspection of weld geometry

The earlier in the production chain discontinuities in the weld area are discovered the better and less expensive it is to modify the weld. If the weld is bigger than necessary the cost and the weight grow, and if the weld is undersized the strength is put at risk. This report contains a summary of a literature survey for finding means for optical measurements of weld geometry. Some of the articles are about existing devices that can measure welds. One is hand-held and is applied on the weld afterwards and compares the data with pre set parameters. Experiments were performed with two different systems to evaluate their capability to capture the weld geometry. The first system is an in - house built system with a laser line diode and a CMOS - camera, the other system is scanCONTROL, and is a device with integrated camera and laser line. Matlab was used to process and analyse data from both systems. Experiments with the first system ended when it was quite obvious that it did not meet the expected result. The laser line projection was too short to cover enough of the weld area and it was hard to process the image to find defects in the weld area. The data from the scanCONTROL system was ready to use and it was quite easy to find different defects and discontinuities in the weld area. It is possible to find the geometry of the weld and it is possible to find defects like spatter, undercut and sharp edges, with laser line projection and camera. The equipment is important in order to extract data useful for analysis.
Developments in additive manufacturing processes: industrial technologies and numerical analyses

In this work the current developments on the numerical simulation of different AM processes are presented. A fully coupled thermo-mechanical framework has been tailored to the analysis of several 3D-printing processes ranging from metal wire feeding to selective melting. The accurate definition of the material deposition is addressed, taking into account actual movement of the heat sourcealong the scanning path as defined for the AM machine. The result is a high-fidelity simulation of the AM process leading to an accurate layer-by-layer building sequence. An advanced high-performance and object-oriented software platform has been enhanced to include the parallel (MPI) FE activation technique used to follow the growth of the geometry according to the fabrication process. The mesh adaptivity strategy makes use of Cartesian voxelization together with octree-type local refinements and global coarsening to keep controlled the total number of elements in the computational domain [1,2] . The thermo-viscoelastic-viscoplastic constitutive model introduced is calibrated and the numerical results are validatedthroughan extensive experimental campaign carried out taking advantage of the partnership with several research center such as:ACCESS (Germany), the NorthwesternPolytechnical University (Xi’an, China), the Monash and RMIT Universities (Melbourne, Australia), IK4-Lortek, Leitat, Eurecat (Spain), among others [3,4] .
The effect of meeting opportunities on local urban residents’ prejudice against migrant children in China

This article explores the effect of meeting opportunities between local urban and nonlocal residents on locals’ prejudice against migrant children in China by focusing on three contexts: friendships, schools and neighbourhoods. China’s hukou policy creates a boundary between urban and rural residents, which also takes the form of locals and nonlocals in rural-to-urban migration. Urban public schools with a mix of local and migrant students offer a chance to observe the intergroup relationships between local and nonlocal students as well as their parents. Using two waves of data from the China Education Panel Survey (CEPS), this study examines how changes in migrant friend groups, schoolmates and neighbours of local children affect changes in their parents’ prejudice, as seen among a sample of 1630 student-parent pairs. With longitudinal data, this study mitigates the effect of reverse causality between intergroup contact and prejudice. The findings show that parents whose children have more migrant friends have less prejudice, under certain conditions. Additionally, more nonlocal students in a school relates to less prejudice, especially among parents who are more embedded in the school life. Furthermore, local families with low socio-economic status experience an increase in prejudice, potentially due to an increased feeling of threat. Additionally, this article finds that prejudiced attitudes spread through the social networks of children and parents at the school level. This study emphasises the importance of different contexts of meeting opportunities and sheds new light on the generalisability of the (extended) contact hypothesis to the understudied context of Chinese internal migration.
CALCULATED LITHOSPHERIC STRENGTH ENVELOPES: IMPLICATIONS FOR UNDERSTANDING ELASTIC AND SEISMOGENIC LAYER THICKNESSES ON MARS

Calculated lithospheric strength envelopes (s) are rheological models of the lithosphere that are useful in understanding the elastic () and seismogenic () thicknesses of the lithosphere. Determinations of Te for Mars using diﬀerent techniques use diﬀerent models of Te as indicated by rheology in LSEs, and LSEs indicate that the diﬀerential stress ﬁelds that cause deformation must be considered in the determination of both Te and Ts. We do not attempt to review the literature here or to rank diﬀerent
Multidisciplinary students on Property core units : comparative analysis of introductory and advanced units

The composition of many professional services firms in the Urban Development area has moved away from a discipline specific ‘silo’ structure to a more multidisciplinary environment. The benefits of multidisciplinarity have been seen in industry by providing synergies across many of the related disciplines. Similarly, the Queensland University of Technology, Bachelor of Urban Development degree has sought to broaden the knowledge base of students and achieve a greater level of synergy between related urban development disciplines through the introduction of generic and multidisciplinary units. This study aims to evaluate the effectiveness of delivering core property units in a multidisciplinary context. A comparative analysis has been undertaken between core property units and more generic units offered in a multidisciplinary context from introductory, intermediate and advanced years within the property program. This analysis was based on data collected from course performance surveys, student performance results, a student focus group and was informed by a reflective process from the student perspective and lecturer/ tutor feedback. The study showed that there are many benefits associated with multidisciplinary unit offerings across the QUT Urban Development program particularly in the more generic units. However, these units require a greater degree of management. It is more difficult to organise, teach and coordinate multidisciplinary student cohorts due to a difference in prior knowledge and experience between each of the discipline groups. In addition, the interaction between lecturers/ tutors and the students frequently becomes more limited. A perception exists within the student body that this more limited face to face contact with academic staff is not valuable which may be exacerbated by the quality of complimentary online teaching materials. For many academics, non-attendance at lectures was coupled with an increase in email communication. From the limited data collected during the study there appears to be no clear correlation between large multidisciplinary student classes and student academic performance or satisfaction.
ONLINE LEARNING: REFLECTIONS ON THE EFFECTIVENESS OF TWO UNDERGRADUATE TOURISM MODULES - SUSTAINABILITY AND CORPORATE SOCIAL RESPONSIBILITY

Action research was chosen since it is an effective way to implement, monitor and evaluate changes to educational curricula. Paradigmatically, action research has an ontological or worldview that is collectively constructed, and an epistemology which is embodied, situated and hermeneutically framed. In this study, the methodology was qualitatively founded. Axiologically, the study was value leaden with a transformation intent of improving educational curricula, specifically, values related to sustainability and corporate social responsibility. The action research participants were the course convenor, tutor, and tourism students involved in the tourism enterprise management course. Empirical materials included qualitative conversations between convenor and tutor, convenor or tutor with students, written learning-teaching materials generated by students as well as reflexive journals kept by the convenor and tutor. The empirical materials were interpreted using constant comparison. During the semester, students engaged in the modules in lieu of regular face to face learning-teaching interactions. The students indicated that the modules were a change from face to face interaction and added variety to the course’s suite of learning contexts. Such independent study experiences increased student reflections and there was a strong appreciation of having a teaching-learning engagement, which did not have to be supported by academic references but rather with student critical reflections. While on the surface, it may appear that the two modules provided students with stand alone learning opportunities, this was not the case. Students were regularly required to engage with module content in lectures, tutorials and assessment tasks. Further, student reflections on their own learning indicated that they had gained broader perspectives and understandings from engagement in the modules and used those in other learning components of the course. Improvements to the “living’ content of the two modules relate to: the constant need for maintenance and review for currency; offsetting module text density and complexity with regard to English language ability of students; clarifying perceptions of repetition; and coaching students’ effective decision-making when offered diversity and choice in media with which to engage. Overall, the modules were an innovation to the course’s teaching-learning engagements and were viewed by the students as effective means to reflexively engage with course content.
Wide-Area Adaptive Protection Using Distributed Control and High-Speed Communications

New concepts of wide-area adaptive protection using distributed control and high-speed communications may reduce the likelihood of catastrophic failures in power systems. We suggest a communication and control structure designed to avoid and/or reduce the impact of misoperations of protection devices, for example, from hidden failures. We propose two different operating modes of the system, anticipative and responsive. We also indicate how such a system can respond to emergencies within the time available.
Structural assessment of a stone masonry wall using a continuum damage model and experimental validation

Understanding how stone masonry structures behave under dynamic horizontal loads yields important information on possible collapse mechanisms and damage progression along the structure. With this in mind a numerical and experimental study was performed concerning the structural behaviour of a stone masonry wall built in situ at the Laboratory of Seismic and Structural Engineering (LESE). The wall was tested under cyclic horizontal load to simulate the effects of a horizontal seismic action. The experimental response allowed assessing the cyclic behaviour and estimating the energy dissipation and ductility capacity of the structure, as well as its strength and stiffness. Afterwards, the wall was simulated numerically in Cast3M [1] using a finite element modelling strategy. The stones, the infill and the joints were simulated considering them as part of a unique homogeneous material and using a non-linear continuum damage model [2] to reproduce the wall’s global behaviour. The final objective of this work is to study the applicability of such continuum numerical models to simulate stone masonry structures, using experimental results as reference values.
