Cling – The New Interactive Interpreter for ROOT 6

Cling is an interactive C++ interpreter, built on top of Clang and LLVM compiler infrastructure. Like its predecessor Cint, Cling realizes the read-print-evaluate-loop concept, in order to leverage rapid application development. Implemented as a small extension to LLVM and Clang, the interpreter reuses their strengths such as the praised concise and expressive compiler diagnostics. We show how to match the interpreter concept to the compiler library and generalize common set of requirements for building up an interactive interpreter. We reason the design and implementation decisions as solution to the challenge of implementing interpreter behaviour as an extension of the compiler library. We present the new features, e.g. how C++11 will come to Cling and how Cint-specific extensions are being adopted. We clarify the state of integration in the ROOT framework and the induced change set. We explain how ROOT dictionaries are simplified due to the new interpreter.
A data system for the security and tracking of goods containers

This paper discusses the need for security of goods in shipping containers against the threat of theft, smuggling and contamination. It shows the need to have integrity and tracking sensors within the container, and to regularly report status and location to control centres. This paper describes work done within the PASR2005 SECCONDD activity towards an international interface standard for secure container data. It discusses the types of communications required from the container’s sensor system, namely: a) long range reporting over the GSM cellular radio system – to be done periodically or when a significant event occurs, and b) short range reporting over a radio link in the 2.4GHz licence-free band. The paper outlines the types of data that need to be sent in the different cases, and discusses the recommended protocols for encoding, protection and communication of the data. These are based around standard protocols, e.g. Transport Layer Security and IEEE 802.15. 4, but adapted where necessary to make transmission of the sensor data efficient, secure and reliable in the shipping container environment. There is a particular issue in a large port where there may be hundreds of shipping containers in radio range of an interrogator device, and where a special radio channel access protocol is required. The paper shows how the system can be implemented in a cost effective, low power device. The paper discusses how the data on location and security status of containers can be used by the relevant trade organisations and law enforcement agencies, e.g. for security risk assessment.
A mapping framework for EDI message translation

Summary form only given. EDI is characterized by the possibility of sending/treating messages between information systems without any human intervention. A large number of translations are needed in order to enable the communication between an enterprise and its suppliers and clients. Therefore, translators and wrappers are needed to enable this task. We define a representative framework to map between different representations. We apply this framework for translating EDI messages. We examine the message translation process and show the problems and lack of existing solutions. We also identify the mapping between different messages. Finally, we suggest the use of semiautomatic transformation tool. This translator differs by being easy to use for managers and people with limited technical skills. It facilitates the task of definition of a large number of translations by using matching techniques between source and target message.
Realization and optimization of AES algorithm on the TMS320DM6446 based on DaVinci technology

The application of AES algorithm in the digital cinema system avoids video data to be illegal theft or malicious tampering, and solves its security problems. At the same time, in order to meet the requirements of the real-time, scene and transparent encryption of high-speed data streams of audio and video in the information security field, through the in-depth analysis of AES algorithm principle, based on the hardware platform of TMS320DM6446, with the software framework structure of DaVinci, this paper proposes the specific realization methods of AES algorithm in digital video system and its optimization solutions. The test results show digital movies encrypted by AES128 can not play normally, which ensures the security of digital movies. Through the comparison of the performance of AES128 algorithm before optimization and after, the correctness and validity of improved algorithm is verified.
Students and Social News

The growth of new media is changing how news organizations publish their work, and the explosion of social networks is changing the way news consumers of all ages share information. As news outlets face an uncertain future and try to reach younger, newer audiences, the rapid growth of mobile devices means new opportunities to create, share, and consume news content. This study examines how young news consumers share and consume news content, specifically whether they are more likely to get news through social networks (Facebook and Twitter) or directly through news sources (news stations, newspapers, websites, and mobile apps). The findings here indicate that students may hear of news through social media, but rely on other internet sources to confirm it. Local news does not seem to carry as much weight with them, but they can be persuaded to pay attention to their college towns, if only for community news and information. The findings of this study could help producers of news content tailor their information to fit these new “publishing” formats to maintain (or perhaps increase) their audience.
Computational Design of a Bio Inspired Responsive Architectural Façade System

This research intends to illustrate a nonlinear relationship that could be drawn between the fundamental processes in living systems and architectural design of responsive surface. The research focuses on deriving a set of parametric relationships from the phenomenon in cell biology and generating an architectural expression of a responsive façade system. The research methods primarily investigates the cell – to – cell connection in mammary epithelial cell system and review the evident relay of communication across the entire system of cells. This thorough investigation unfolds the logical parameters of the biological system that delineates the dynamic feedback mechanism and changes in the cell surface conditions initiated from the changes in the extracellular environment (ECM). The research findings of this complex mechanism are further translated though parametric modeling tool (in this case Generative Components) to model the causalities of the changes in cell environment and surface condition changes. In the next phase of our research we have explored the architectural utility of this hybridized model operating in a user defined controlled environ, and not just a mere response to biological stimulus.
Robust controller design with genetic algorithm for flexible spacecraft

A class of energy-based position controllers for a kind of flexible spacecraft is proposed. Closed-loop stability of the original distributed parameter system can be achieved, as well as asymptotic stability for the truncated system, which is obtained through representing the deflection of the appendage by an arbitrary finite number of flexible modes. The feedback gains of the controller are tuned by a genetic algorithm (GA) optimization process to achieve good results for tip motion based on some suitable fitness functions. Numerical simulations are carried out on a kind of spacecraft with one flexible appendage, and satisfactory results are obtained.
Virtual learning environments (VLEs) for distance language learning: shifting tutor roles in a contested space for interaction

This article describes the rationale for pedagogical, technological and organisational choices in the design of a virtual learning environment (VLE) for an upper-intermediate Spanish course with regard to the roles of participants (tutors, moderators and learners). We report on findings from a preliminary evaluation of the interaction between the different actors and this space, using quantitative and qualitative data obtained from interviews, questionnaires and analysis of usage logs. We look at the tensions that emerge as tutors and learners adopt new roles and engage in new pedagogical relationships around the opportunities afforded by this kind of teaching and learning space. We argue that our attempt to promote interaction through our VLE model has resulted in a contested space where traditional hierarchies and relationships between tutors and learners are in a state of flux and where new hierarchies and relationships are constantly being forged. Finally we explore new ways in which tutors’ roles might be organised to more effectively fulfil their supportive and facilitative functions in this new online environment.
Redundancy reduction as the basis for visual signal processing

An environmentally driven, self-organizing principle for encoding sensory messages is proposed, based on the need to learn their statistical properties. Optimal encodings are found for two cases: First, for linear maps the optimal transformation eliminates pairwise correlations between input `pixels. ' This solution is applied to predict the retinal transform based on the autocorrelator for natural scenes. Second, when the input `images' consist of a set of weakly coupled, local `bound states,' then a series of non-linear maps is found which optimally segments the input. This is demonstrated by using it to efficiently learn, without supervision, the statistics of English text.
A RECONFIGURABLE 3D ENGINEERING SHAPE SEARCH SYSTEM PART I: SHAPE REPRESENTATION

This paper presents an approach for a reconfigurable shape search system for 3D engineering models using a client-serverdatabase architecture. The current paper focuses on the server functionality, while a subsequent paper will focus on the database issues. The server takes the shape query as input from the client and converts it into feature vectors and a new skeletal graph representation which we have developed. The algorithms such as voxelization, skeletonization, and skeletal graph extraction for accomplishing these are described in detail. The principal advantages of the skeletal graph representation are that (i) it preserves the geometry and topology of the query model, (ii) it is considerably smaller than the B-Rep graph, and (iii) it is insensitive to minor perturbations in shape, while sensitive enough to capture the major features of a shape. Our representation is also synergistic with the human cognitive representation of shape. The results indicate that the skeletal graph is considerably smaller than the B-Rep graph even for complicated shapes.Copyright © 2003 by ASME
An approach to tracking motion of mobile robot for moving object

This paper describes a tracking motion to follow a moving object in mobile robot system. Here a realization of obstacle avoidance motion is an important issue to track moving object continuously. To address the above issue, in this paper, the tracking strategy with a virtual goal under the well-known environment is proposed. Then a switching algorithm of tracking and obstacle avoidance motion is also taken up. To achieve the smooth switching, a virtual object is introduced, and a tracking motion is considered according to the virtual object. Several numerical and experimental results are shown to confirm the proposed tracking algorithm.
Assessment of Awareness, Perceptions, Skills and Motivation of Undergraduate Medical Students 'research In Physiology-A Pilot Study

Background: Training in research is gaining great importance at the undergraduate level. The subject of physiology forms the foundation of clinical subjects hence it becomes the fundamental constituent of medical curriculum. The evidence obtained from classroom assessment supports the effectiveness of computerized data recording systems in self-learning, motivation, improved performance, and skills development in undergraduate courses in a range of disciplines. Objectives: Our assessment aimed to (a) evaluate students’ awareness of research activities, (b) compare students’ perceptions of their soft and researchspecific skills competencies, and (c) determine students’ motivation for research. Methods: A pilot study was conducted using the questionnaire modified from (CETL-AURS) at Reading University having both closed ended and open ended questions completed by twenty, first and second year MBBS students session 2013-2014 of Shalamar Medical and Dental College, Lahore. It was a concurrent mixed study design. Internal consistency of items in the study questionnaire (Chronbachs’ Alpha in range of 67 to 88) was determined using SPSS version 17. Descriptive statistics for quantitative data was used. Thematic analysis was done for qualitative data. Results: Most of the students were moderately motivated to plan research projects. Male students appeared to be the more confident regarding their research skills competencies. Although all students recognized the role of research in medical practice, many were unaware of the medical research activities within their college. A common perception was that research should be done using Power Lab especially in respiratory and cardiovascular physiology. Conclusion: This study will help in planning guided research projects by students. The use of Power Lab and Lab tutor software will enhance self directed learning and will thereby build better concepts in physiology for the student. Students will enjoy group learning and this will create an encouraging environment for instilling curiosity on the part of the student.
Patent semantics : analysis, search and visualization of large text corpora

Patent Semantics is system for processing text documents by extracting features capturing their semantic content, and searching, clustering, and relating them by those same features. It is set apart from existing methodologies by combining a visualization scheme that integrates retrieval and clustering, providing a variety of ways to find and relate documents depending on their goals. In addition, the system provides an explanatory mechanism that makes the retrieval an understandable process rather than a black box. The domain in which the system currently works is biochemistry and molecular biology patents but it is not intrinsically constrained to any document set.
Mapping Based Energy Efficient Counter Design on FPGA

— In this work, 8-bit counter power optimized counter is designed with help of energy efficient techniques called mapping and simulation activity file in format of Value Change Dump (VCD) file and setting file (*.xpa) to define toggle rate, activity rate and enable rate for the power consumption estimation in order to get energy efficient design. With mapping, there is 33.33%, 34.61%, 36.5%, 36.49%, 36.86%, 36.9% dynamic power reduction in counter when device is operating on 10MHz, 100MHz, 1GHz, 10GHz, 100GHz and 1 THz frequency. This reduction achieved by mapping control signal to control port in place of mapping control signal to LUT (Look Up Table) input. In Resource utilization, when we are mapping the control signal to control port, there is 70.58% less number of LUT and 39.89% less number of IO usage than mapping the control signal to LUT inputs. Spartan-3 FPGA is taken as target device and Xilinx 14.1 ISE is taken as design, synthesis and implementation tools. Verilog HDL(Hardware Description Language) is used to synthesize the counter on FPGA. The power dissipation of the FPGA based energy efficient design is verified using Xilinx XPower tool.
Exploring the mental lexicon: A methodological approach to understanding how printed words are represented in our minds

Visual word recognition is a capital stage in reading. It involves accessing a mental representation of a written word, including processes such as perception, letter coding and selection of the proper candidate in our mental lexicon. One key issue for researchers on this field is to shed light on the role of phonological and orthographic processes in lexical access, as well as the choice of an input coding scheme for orthographic representations. In this paper we will review the state of the art about sublexical and lexical processes involved in lexical access. We will discuss behavioral, eye movement and electrophysiological evidence to understand: (i) which are the most important coding units, (ii) how our visual system codes identity and position of such units, (iii) which factors modulate the way we access lexical information in our minds, and (iv) the time course of such processes. We will do so from a methodological perspective, exploring a broad range of paradigms and effects that provide a complete framework about how printed words are coded and represented in our minds.
Supporting and Exploiting Spatial Memory in User Interfaces

Spatial memory is an important facet of human cognition – it allows users to learn the locations of items over timeand retrieve them with little effort. In human-computer interfaces, a strong knowledge of the spatial location ofcontrols can enable a user to interact fluidly and efficiently, without needing to visually search for relevant controls. Computer interfaces should therefore be designed to provide support for developing the user's spatial memory,and they should allow the user to exploit it for rapid interaction whenever possible. However, existing systems offervarying support for spatial memory. Many modern interfaces break the user's ability to remember spatial locations, bymoving or re-arranging items; others leave spatial memory underutilised, requiring slow sequences of mechanical actionsto select items rather than exploiting users' strong ability to index items and controls by their on-screen locations.The aim of this paper is to highlight the importance of designing for spatial memory in HCI. To do this, we examine theliterature using an abstract-to-concrete approach. First, we identify important psychological models that underpin ourunderstanding of spatial memory, and differentiate between navigation and object-location memory (with this reviewfocusing on the latter). We then summarise empirical results on spatial memory from both the psychology and HCIdomains, identifying a set of observable properties of spatial memory that can be used to inform design. Finally, weanalyse existing interfaces in the HCI literature that support or disrupt spatial memory, including space-multiplexeddisplays for command and navigation interfaces, different techniques for dealing with large spatial data sets, and theeffects of spatial distortion. We intend for this paper to be useful to user interface designers, as well as other HCIresearchers interested in spatial memory. Throughout the text, we therefore emphasise important design guidelinesderived from the work reviewed, as well as methodological issues and topics for future research.
An improved approach of register allocation via graph coloring

Register allocation is an important part of optimizing compiler. The algorithm of register allocation via graph coloring is implemented by Chaitin and his colleagues firstly and improved by Briggs and others. By abstracting register allocation to graph coloring, the allocation process is simplified. As the physical register number is limited, coloring of the interference graph can’t succeed for every node. The uncolored nodes must be spilled. There is an assumption that almost all the allocation method obeys: when a register is allocated to a variable v, it can’t be used by others before v quit even if v is not used for a long time. This may causes a waste of register resource. The authors relax this restriction under certain conditions and make some improvement. In this method, one register can be mapped to two or more interfered “living” live ranges at the same time if they satisfy some requirements. An operation named merge is defined which can arrange two interfered nodes occupy the same register with some cost. Thus, the resource of register can be used more effectively and the cost of memory access can be reduced greatly.
A natural sketching environment : bringing the computer into early stages of mechanical design

Current computer-based design tools for mechanical engineers are not tailored to early stages of design. Most designers use pencil and paper at first, and input their design into CAD systems only after it is nearly complete. The tradeoff between the ease of drawing and the precision of a CAD tool is too great for engineers who are just sketching out rough designs. This thesis presents a tool that is specifically geared toward the earlier stages of design. Our system interprets and represents sketches as the user sketches them, then allows the user to simulate her system using a twodimensional kinematic simulator. This thesis introduces a method for translating a sketch into the designer’s intended mechanical devices, despite ambiguities in the sketch.

JSSlicer: A Static Program Slicing Tool for JavaScript

The rapid development of Web 2.0 leads scripting language such as JavaScript to be ubiquitous in web pages; however the dynamic nature and flexibility of JavaScript make its development, debugging, maintenance, and reuse difficult. To improve the efficiency and accuracy of JavaSript security analysis, we propose a new JavaScript analysis method based on program slicing, together with a prototype-implemented JavaScript slicing tool, named JSSlicer. We also present a proof-of-concept application example of JSSlicer where an example of the common mode failure problem is tackled.

Recognition of the importance and measurement of the particulars of snowpack micro-structure challenge traditional modeling approaches. Simulation methods are examined in relation to the demands of millimeter wave sensing. Distinctive features and critical issues include treatment of near surface micro-structure, medium anisotropy and density, polarization effects, moisture content, and multi-scale surface roughness. <<ETX>>
Fibre tracking: probabilistic approach and preliminary results

Fibre tracking: probabilistic approach and preliminary results The aim of this work is to have a preliminary experience with probabilistic tractography. We performed fibres reconstruction for three tracts of interest with data obtained from two MR imaging units equipped with different gradients system. An acquisition protocol optimization has been necessary in order to obtain a good trade-off between image quality and data collection time. Possible solutions to acquisition and processing problems are discussed. Future developments and possible applications in neurosurgery are also suggested.
Distributed Power Control by Completion Time Minimization in Wireless Multi-hop Networks ⋆

In this paper, we consider the problem of distributed power control over ad hoc wireless networks. We formulate the power control problem as a convex optimization problem that minimizes the summation of packets completion time at each node. We then explore the problem structure and propose a distributed method to solve the problem where each node only need information exchange with its neighbors. Finally, we illustrate the algorithm and the associated implementation issues with a simulation example.
