Malignant and benign tumors of bone in the foot have traditionally been characterized as rare, or at least unusual. When these lesions do appear, mostly used methods, for foot and ankle tumors detection, are Ultrasound, Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). There is a lot of image segmentation techniques are available. In this paper we are analyzing Computed Tomography images through Computer Aided Diagnosing (CAD) system. And for edge detection in image, canny edge detector is used. Canny edge detector has some limitations like it is not able to distinguish edges occurring around objects but still it is beneficial than other traditional edge detector *** to make the Canny edge detector better at identifying contours in natural images, in this paper some improved canny edge detector are analyzed.

Currently, manual inspection and off-line inspection play an important role in the inspection methods of machining process, which severely restricts the development of inspecting automation. In the paper, automatic programming system for machining center on-line inspection was developed by secondary development kit object ARX of AutoCAD. Inspecting datum was obtained, inspecting process planning was laid up and inspecting program was made automatically. The inspection can be applied to automatic workpiece setting up, on-line inspection of workpiece, data processing, quality analysis and compensation of machined workpiece errors, which led to increase precision, production efficiency and quality and reduced the rate of rejection and tool damage.

The article proposes an enhanced behavior model using graphs of state transitions. The properties and advantages of the proposed model are discussed, UML-based Cooperative Interaction of Automata Objects (CIAO) language is described, attribute approach on its parsing mechanism is introduced. The proposed model for describing behavior is aimed at achieving higher reliability and productivity indicators when designing the secure architecture and implementing reactive and distributed systems in comparison with traditional methods. A side-by-side goal is to create a convenient publication language for describing parallel algorithms and distributed reactive systems. The offered model has advantages under certain conditions in comparison with other models of behavior description in the field of the description of asynchronous distributed reacting systems.

Welding technique is widely used in industrial production, and it also indicates the industrialization of a country. The traditional way of welding consumes much manpower and time and cannot solve the problem of low accuracy. With the development of industrial robot, those problems could be well solved. In this article, we introduce a welding production line based on industrial robot. We take the welding of accessories of auto for instance, researching the key technologies of welding production line based on industrial robot. Such as the identification of welding position based on machine vision, the CAD automatic programming technology aimed at different accessories. At the same time we create the 3-D digital simulation of the production line to test whether it is practicable.

Big Data query systems represent data in a columnar format for fast, selective access, and in some cases (e.g. Apache Drill), perform calculations directly on the columnar data without row materialization, avoiding runtime costs. However, many analysis procedures cannot be easily or efficiently expressed as SQL. In High Energy Physics, the majority of data processing requires nested loops with complex dependencies. When faced with tasks like these, the conventional approach is to convert the columnar data back into an object form, usually with a performance price. This paper describes a new technique to transform procedural code so that it operates on hierarchically nested, columnar data natively, without row materialization. It can be viewed as a compiler pass on the typed abstract syntax tree, rewriting references to objects as columnar array lookups. We will also present performance comparisons between transformed code and conventional object-oriented code in a High Energy Physics context.

Genetic Improvement (GI) is the process of using computational search techniques to improve existing software e.g. in terms of execution time, power consumption or correctness. As in most heuristic search algorithms, the search is guided by fitness with GI searching the space of program variants of the original software. The relationship between the program space and fitness is seldom simple and often quite difficult to analyse. This paper makes a preliminary analysis of GI's fitness distance measure on program repair with three small Python programs. Each program undergoes incremental mutations while the change in fitness as measured by proportion of tests passed is monitored. We conclude that the fitnesses of these programs often does not change with single mutations and we also confirm the inherent discreteness of bug fixing fitness functions. Although our findings cannot be assumed to be general for other software they provide us with interesting directions for further investigation.

On-demand computing, Software-as-a-Service, Platform-as-a-Service, and in general Cloud Computing is currently the main approach by which both academic and commercial domains are delivering systems and content. Nevertheless there still remains a huge segment of legacy systems and application ranging from accounting and management information systems to scientific software based on classic desktop or simple client-server architectures. Although in the past years more and more companies and organizations have invested important budgets in translating legacy apps to online cloud-enabled environment there still remains an important segment of applications that for various reasons (budget related in most cases) have not been translated. This paper proposes an innovative pipeline model architecture for automated translation and migration of legacy application to cloud-enabled environment with a minimal software development costs.

Existing methods for visual reasoning attempt to directly map inputs to outputs using black-box architectures without explicitly modeling the underlying reasoning processes. As a result, these black-box models often learn to exploit biases in the data rather than learning to perform visual reasoning. Inspired by module networks, this paper proposes a model for visual reasoning that consists of a program generator that constructs an explicit representation of the reasoning process to be performed, and an execution engine that executes the resulting program to produce an answer. Both the program generator and the execution engine are implemented by neural networks, and are trained using a combination of backpropagation and REINFORCE. Using the CLEVR benchmark for visual reasoning, we show that our model significantly outperforms strong baselines and generalizes better in a variety of settings.

In order to control the machining process of Direct-Write based on Near-field Electrospinning automatically, an automatic programming system used for an open architecture CNC system is proposed in this paper. This system descirbes the machining trajectory via the 2D CAD drawing, from which the data is extracted by the system. According to the processing parameters, the data is classified and reordered, and NC codes are automatically generated. The system solves the problem in integrating the design and machining, makes it more convenient to experimental research and realizes patterned fabrication of micro/nano-structure, which provides a good experimental base for the development of electrospinning technology.

programming of graphical interaction and modular structure are adopted in this wire cutting machine software by analyzing the structure of DXF file, picking out the part's outline information in Visual C++ 6.0, and combining the manufacture conditions in this paper. The NC codes are obtained which are consistent with the high-speed cutting machine processing system automatically. This system software greatly facilitates the process of high speed cutting machine, shortens programming time and improves the accuracy of the programming.
