Twist Drills

The study presents a new method, developed by the authors, for producing twist drills by extrusion using a three-slide forging press. The method consists in using two sectional dies with specially shaped impressions that allow the removal of a ready drill from the die without unscrewing. The study describes the main assumptions of the new method for twist drill extrusion, discussing benefits offered by this method when compared to the conventional process for producing twist drills by extrusion using a monolithic die. In order to verify the proposed solution, dies conforming to the assumptions of the new method were designed and executed. Experimental tests were conducted under laboratory conditions using a three-slide forging press. The model of the material used in the experiments was assigned the properties of Pb1 lead. As a result of the experiments, the theoretical assumptions of the new method could be examined and its practical application verified. Also, ideas for further research aimed at better understanding of the new technology for producing twist drills by extrusion are presented.

Snow Water

Hydraulic conveying of snow is one of the most promising techniques for snow removal from an urban area. The method for measuring the fraction of snow in a snow-water mixture flowing in a pipe is a key technique for its practical application. A new method based on the conductometric method has been developed in this study. The method was tested using a prototype snow-fraction meter in a testing apparatus and a closed pipeline system. This type of meter has the advantage of in situ measurement of a wide fraction range from zero up to packed value. The meter is capable of quick response, independent of flow velocity or snow properties and nonintrustive in flow. This paper describes the application of techniques for the development of the meter and the test results. This new method is expected to be useful for hydraulic conveying of ice particles or ice cubes, a new technology in the air-conditioning field.

The paper presents a new method for forming a hollow shaft with a triangular rosette-shaped flange on its end. The part being investigated is used as a propeller shaft in helicopters. The product must be monolithic, therefore it cannot be produced by methods which consist in joining a flange with a tube. Up till now, such shafts have been produced by machining from solid barstock, the process which generates material losses exceeding 90%. The application of the proposed flanging method results in a significant reduction in both material and labour consumption, which leads to lower production costs. Due to beneficial texture of the shaft flange, shafts produced by this method exhibit better strength properties than shafts produced by machining. The paper presents the results of a numerical analysis of the flanging process, performed using DEFORM-3D software. Also, experimental tests were conducted using a three-slide forging press. Theoretical and experimental results obtained confirm the effectiveness of the new method for forming this part.

Advertising is a broad concept; in this book, the authors have presented a precise look at its practical domains. Modern advertising has become low-cost with fast access to target users, transferring a persuasive concept to customers and getting a positive behavioral reaction. The last part of their definition is indicative of a new method of advertising, which goes a step further than other methods. A positive reaction embedded in an advertising function comes from advertisers’ use of new communicational practices to transfer and receive messages. The emergence and application of new technology necessitates using the appropriate tools. In this chapter, the authors first define these new tools (strategies). Then, they discuss the differences between online and traditional advertising strategies, and offer an integrated model of Internet advertising strategies. Finally, the authors introduce different kinds of appropriate Internet advertising strategies. The purpose of this chapter is to focus on online advertising strategies and provide a fundamental understanding of their relationship to marketing practices. They examine why firms must use online advertising strategies and give some examples of how online advertising strategies can help companies make sound marketing decisions.

Purpose Periodic inspection of large tonnage vessels is critical to assess integrity and prevent structural failures that could have catastrophic consequences for people and the environment. Currently, inspection operations are undertaken by human surveyors, often in extreme conditions. This paper aims to present an innovative system for the automatic visual inspection of ship hull surfaces, using a magnetic autonomous robotic crawler (MARC) equipped with a low-cost monocular camera. Design/methodology/approach MARC is provided with magnetic tracks that make it able to climb along the vertical walls of a vessel while acquiring close-up images of the traversed surfaces. A homography-based structure-from-motion algorithm is developed to build a mosaic image and also produce a metric representation of the inspected areas. To overcome low resolution and perspective distortion problems in far field due to the tilted and low camera position, a “near to far” strategy is implemented, which incrementally generates an overhead view of the surface, as long as it is traversed by the robot. Findings This paper demonstrates the use of an innovative robotic inspection system for automatic visual inspection of vessels. It presents and validates through experimental tests a mosaicking strategy to build a global view of the structure under inspection. The use of the mosaic image as input to an automatic corrosion detector is also demonstrated. Practical implications This paper may help to automate the inspection process, making it feasible to collect images from places otherwise difficult or impossible to reach for humans and automatically detect defects, such as corroded areas. Originality/value This paper provides a useful step towards the development of a new technology for automatic visual inspection of large tonnage ships.
