We introduce the k-LWE problem, a Learning With Errors variant of the k-SIS problem. The Boneh-Freeman reduction from SIS to k-SIS suffers from an exponential loss in k. We improve and extend it to an LWE to k-LWE reduction with a polynomial loss in k, by relying on a new technique involving trapdoors for random integer kernel lattices. Based on this hardness result, we present the first algebraic construction of a traitor tracing scheme whose security relies on the worst-case hardness of standard lattice problems. The proposed LWE traitor tracing is almost as efficient as the LWE encryption. Further, it achieves public traceability, i.e., allows the authority to delegate the tracing capability to "untrusted" parties. To this aim, we introduce the notion of projective sampling family in which each sampling function is keyed and, with a projection of the key on a well chosen space, one can simulate the sampling function in a computationally indistinguishable way. The construction of a projective sampling family from k-LWE allows us to achieve public traceability, by publishing the projected keys of the users. We believe that the new lattice tools and the projective sampling family are quite general that they may have applications in other areas. © 2014 international Association for Cryptologic Research.

Web robots are software applications that run automated tasks over the internet. They traverse the hyperlink structure of the World Wide Web so that they can retrieve information. There are many reasons to distinguish web robot requests and user requests. Some tasks of web robots can be harmful to the web. Firstly, Web robots are employed for assemble business intelligence at e-commerce sites. In such a state of affairs, the e-commerce site may need to detect robots. Secondly, many e-commerce sites carry out Web traffic scrutiny to deduce the way their customers have accessed the site. Unfortunately, such scrutiny can be erroneous by the presence of Web robots. Thirdly, Web robots often consume considerable network bandwidth and server resources at the expense of other users. A web log file is a web server file automatically created and maintained by a web server to check the activity performed by it. It maintains a history of page requests on its site. In this paper we have used four methods together to detect and finally confirm requests as a robot request. Experiments have been performed on the log file generated from the server of an operational web site named *** which contains data of march-20l3. In our research results o.f web robot detection using various techniques have been compared and an integrated approach is proposed for the confirmation of the robot request.

Social robotics is an emerging field, with many applications envisioned. Scientific and technological advancements constantly impact humans on the individual and societal level. Therefore one question increasingly debated is how to anticipate the impact of a given envisioned, emerging or new scientific or technological development and how to govern the emergence of scientific and technological advancements. Anticipatory governance has as a goal to discuss potential issues arising at the ground level of the emergence of a given scientific and technological product. Our study investigated a) the visibility of the anticipatory governance concept within the social robotic discourse and b) the implication of anticipatory governance for the social robotics field through the lens of a social robot design process and key documents from the UNESCO/ICSU 1999 World conference on Sciences the lens. Our findings suggest that a) anticipatory governance is not a concept established within the social robotics fields so far;b) that social robotics as specific field is not engaged with within the anticipatory governance field and c) that many professional and academic fields are not yet involved in the social robotics discourse as aren’t many non-academic stakeholders. We posit that anticipatory governance can strengthen the social robotics field. © Springer international Publishing Switzerland 2014.

The mobile industrial manipulator(MIM) which combines the advantages of both the mobile robot and industrial robot and owns powerful mobility, flexibility and functionality will be the next generation of robots. However fully autonomous MIM performing various tasks in unstructured or semi-structured environment is very challenging in autonomous localization & navigation, object identification, control and coordination. However, there is a demand in industry for MIMs to be deployed in hazardous, dangerous and/or remotely environments. Therefore, a semi-autonomous MIM is investigated to perform industrial operations. An MIM prototype using a mobile platform and an industrial robot is developed. Manual and autonomous methods are proposed and implemented to control the prototype manually and autonomously. Experiments using the prototype were performed. Experimental results demonstrate that the robot can run autonomously if there is no ambiguity and the operators can interrupt the autonomous mode at any time if needed. The developed prototype and proposed methods have big potential in industrial applications.

Vision-based without camera calibration control of uncalibrated industrial robots is a challenging research problem. To address the issue, a vision-based industrial robot servoing control system has been developed with the CSM algorithm being adopted in this paper. The software and hardware of this system as well as the direct and inverse kinematics equations which map joint space into "camera space" have been described. The control strategy has been proposed and applied to the CSM-based industrial robot servoing control system. The experiments of robot positioning were performed on the developed CSM-based robot control system without camera calibration to validate the accuracy and real-time performance of the system. Experimental results show that the accuracy can reach approximately 0.3mm in 3-dimensional robot space, and the real-time performance of the system can satisfy the requirements of most industrial applications.

The emotional intelligence and affective computing are the hot point in artificial intelligence research. Based on the assumption of certainty, man had achieved good results on development and research, but already fade. The root is to ignore emotional intelligence of uncertainty situation. And emotional intelligence impacts on affective computing not only depending on technology development of computer, also depending on how to face up and to develop uncertainty. The fear of uncertainty and reasonable development of affective computing help to avoid ethical revolt.

Recent advances in automation and sensor technology have enabled the use of industrial robots for complex tasks that require intelligent decision making. Vision sensors have been the most successfully used sensor in many high value industrial applications. Over the recent years, weld seam tracking has been a topic of interest, as most of the existing robotic welding systems operate on basis of pre-programmed instructions. Such automated systems are incapable of adapting to unexpected variations in the seam trajectory or part fit-up. applications such as tungsten inert gas (TIG) welding of aerospace components require high tolerances and needs intelligent decision making. Such decision making procedure has to be based on the weld groove geometry at any instance. In this study, a novel algorithm along with an automated system was developed for estimating the joint profile and path tracking of a three dimensional (3D) weld groove. A real-time position based closed-loop system was developed with a six axis industrial robot and a laser triangulation based sensor. The system was capable of finding the 3D weld joint profile and position in real-time, and make intelligent decisions accordingly. Raw data from a vision sensor was processed through a novel algorithm to obtain X and Z co-ordinates at an accuracy of 8.3μm and 43μm respectively at an acquisition speed of 2.5 profiles per second. The algorithm was also capable of measuring the weld gaps with an accuracy of 28μm. Finally, the developed system was successfully used for three dimensional seam tracking, and demonstrates an accuracy of ±0.5mm at a tracking a speed of 2mm/s.
