Editorial

At the start of my Ph.D. in 1980, I caught a glimpse, purely by chance, of the emerging field of computer-aided design (CAD). It intrigued and fascinated me to such an extent that I ended up scrapping my original plans, switching schools and changing my research area. Even though my new school, Ohio State, was one of only a handful of schools with computing facilities dedicated to CAD, I ran into stiff resistance when I expressed my desire to get a Ph.D. in CAD. I was told that CAD was hardly an intellectually challenging field worthy of a Ph.D. dissertation. I was directed to consider mainstream mechanical engineering areas, such as solid mechanics, vibrations, kinematics, and dynamics. The closest I could get to CAD was to do my dissertation in FEA, which allowed me to do at least part of my work in computing and visualization.When I began my academic career at Arizona State, I thought I was finally free to pursue my true love. But I soon realized that we were still a fringe group; faculty in traditional fields, such as thermofluids and solid mechanics, took a dim view of computational research. The proposed thesis plan for my first graduate student (Expert System for Conceptual Synthesis of Frame Structures) was rejected by the Graduate Chair, who remarked “This is not mechanical engineering.” He viewed it as purely a computer program without any regard for the fact that we needed to explicate, structure, and represent experiential knowledge for structural synthesis not found in any textbook on the subject.Of course, I was not alone in facing this predicament. Fortunately, for misfits like us there was an ASME Division that welcomed us. Originally named the Computer Engineering Division (CED), and later known as Computer & Information Engineering (CIE) Division, it was approved in 1979 and began operating in 1980. Unlike academia, industry was well aware of the potential of computing and information technologies to revolutionize product design and manufacturing. Visionaries from computer industry (CDC, IBM, DEC, Applicon), an infant software industry (SDRC, CV, Swanson), and a variety of OEMs (GM, GE, McDonnell-Douglas) led a grassroots effort to convince ASME of the importance of mechanical engineers active participation in these evolving areas through the creation of a new Division. The first CED newsletter in 1981 boldly heralds “…the dawn of an era that is certain to be dominated by computer technology. All projections indicate that mechanical engineers, more than any other professional group, will be more involved in the utilization of this (computer) technology.” They saw MEs playing as important a role in the IT revolution as their far predecessors had in the industrial revolution—a prediction that was to come true.Prof. Ali Seirig was appointed the first Chair of CED. I am in awe of the progress this new Division made in just the first two years. Twenty-four technical committees were set up and an annual conference was initiated in 1981. This conference was unique in that it was associated with an exhibition of the latest hardware and software from leading vendors. This element was critical in keeping the ASME community well informed about the current state of engineering computing. It is, therefore, not surprising to see that this Division was heavily industry dominated—21 out of 24 Technical Committee Chairs were from industry. Sadly, today industry participation in CIE has sagged. Did CIE change because industry participation diminished, or did industry reduce its participation because CIE became less relevant to their needs? We can only speculate about the reasons.CED soon became the fastest growing Division within ASME. The CED/CIE conference and exhibition attracted participants from a wide range of areas, not just CAD/CAM and FEA but kinematics, robotics, heat transfer, and fluid mechanics. This diverse community only had one thing in common, the application of computational methods to problems in their respective fields. As traditional conferences and journals gradually came around to seeing computational methods as valuable contributions in their own fields, they became more accepting of papers of this nature. Thus began the return of computational researchers back to their own discipline communities, shrinking the size of CIE conferences. Finally, in 1994, the CIE conference was colocated with Design Engineering Technical Conferences (DETC).The founders of CED debated the type of journal they needed to have. They felt that given the rapid evolution of computing technologies, an archival journal like an ASME Transactions was not appropriate. At the same time, they wanted their journal to be more technical than a trade magazine. They ended up creating a “hybrid” quarterly publication called CIME (Computers in Mechanical Engineering), with Ali Seirig as its editor. This magazine was produced in full color and was very informative about the latest developments in engineering software. In the words of the editor, CIME was “user-oriented” not “research oriented.” Unfortunately, this philosophy did not command much respect in academia and eventually CIME was merged into ASME’s monthly magazine Mechanical Engineering.And so it came to be that unlike all other ASME conferences and Divisions, CIE did not have any associated journal. Over the years, CIE leaders made several attempts at getting a Transactions journal approved, but to no avail. Reasons for rejection ranged from “computing technologies have no archival value” to the failure to sustain CIME magazine.In 2000, a small group of CIE Division “activists” decided to make another push for a journal. Yong Se Kim, David Lee, Simon Szykman, and David Rosen were the principals in this effort. They came up with a strategy based on lessons from past failures. That included building alliances with three other Divisions (Design, Manufacturing, and Systems & Controls), and demonstrating that an editorial board could be formed with well known researchers who had extensive publication records. I became aware of this effort when I received a call out of the blue, asking me the intriguing question “How would you like to be the Chief Editor of an ASME Transactions?” Of course, the very next sentence brought me down to earth quickly “…the problem is that the journal doesn’t yet exist – will you help us get it approved by ASME?” Thus began my involvement with this journal. We put together an impressive editorial board that included two NAE members and research leaders in each of our targeted areas. Phil Divitero, ASME Director of Publications, immediately saw the marketing potential of this journal, and became a key ally. Bahram Ravani, DED Chair, gave valuable advice on writing our proposal to ASME. Art Erdman, himself a CIE pioneer, happened to be the Chair of ASME Publication Committee, which had authority of approving new journals, which gave us a much needed sympathetic ear on the committee to make our case. In a café in Chicago, before our presentation, we brainstormed various names for the journal and settled on Journal of Computing & Information Science in Engineering (JCISE). The journal was approved and began publishing in the first year of the new millennium, 2001. The CIE Division finally had an archival journal of its own with three cosponsoring Divisions. In 2005, after much lobbying and deliberation, the Design Engineering Division became an equal partner with CIE—an important step in going mainstream.From the very beginning we decided to focus sharply on computational methods for mechanical product development. This set us apart from journals from private publishers that accepted everything and anything related to computing—from gaming to geology, from biology to every branch of engineering. We did not want to dilute our journal with such a wide and general scope. We stipulated that every paper submitted to JCISE must demonstrate applications of its techniques to mechanical design, mechanical analysis, product manufacturing, or quality assurance. Through several iterations we settled on eight major categories to include within the scope of our journal: solid modeling (including parametrics), computational geometry (including reverse engineering), computational metrology (including CMM and tolerance modeling), haptics and virtual reality, engineering informatics, simulation (including FEA, meshing, and optimization), AI/Knowledge based systems, and computer aided manufacturing. Given the practical nature of our field, we also decided to publish papers along two tracks: Research and Application. The latter has subcategories of Software Reviews, Technology Reviews, Tech Notes, and Industry Pilot Projects. The idea was to keep the journal relevant to industry as well as academia. We instituted a three-level rigorous review process for appointment of Associate Editors. We owe it to the founding editorial board for setting sound policies that resulted in quick recognition of JCISE as an archival publication of high quality. That group consisted of Paul Wright, David Rosen, Nick Patrikalakis, Deba Dutta, Susan Urban, Martti Mantyla, Dana Nau, S. Jayaram, Pradeep Khosla, Harry Cheng, and Ravi Rangan. Since we see ourselves as being at the intersection of computer science and mechanical engineering, it was appropriate to have about half of the AEs from each field, and we managed to do so.ACM (Association for Computing Machinery) approached us in 2001 to become an official cosponsor—an offer we gladly accepted in order to strengthen the linkage with our computer science colleagues. From 2001 to 2004, we published a special issue annually drawn from the best papers of the ACM Solid Modeling conferences. Unfortunately, this conference series became too broad, and it was difficult to accommodate their best papers in JCISE without violating our objective of serving the engineering community; this annual tradition of ACM special issues had to be discontinued.ISI included JCISE in its data collection in 2004; after 3 years of this process, the first Impact Factors for JCISE became available in 2007 (for the 2004–2006 period). With respect to ISI Impact Factors, JCISE ranks in the top third of all ASME Transactions; it is better than many long established journals in CAD/CAM and AI areas. Our Impact Factor has continued to improve each year. How meaningful are such statistics in gauging the quality of a journal is debatable. More meaningful metrics are in the offing and we hope they will supplant bean counters of today.When we opened shop in 2000, ASME did not have any web based tool for paper submission and review management. Being the journal focused on computing and information science, we refused to conduct paper reviews the old fashioned way and began developing eLane. With the help of one of our associate editors, Susan Urban, a database expert, and one of her brilliant students, Anish Shah (no relation), we designed and implemented eLane over a period of 3 years. For the past 10 years, we have hosted, maintained, and continuously improved eLane to support not only JCISE but also other journals, such as Research in Engineering Design, and CIE, DTM, and NSF Grantees conferences. eLane blazed a new trail and guided ASME to develop its own “Journal Tool.” Data security and confidentiality is a critical issue in online systems. I am particularly indebted to one of our founding associate editors, Simon Szykman, who provided valuable advice on security aspects of the system by constantly trying to enter the system through unintended holes. It is no surprise that Simon went on to become the first Director of the Cyber-Security group at US Department of Homeland Security and is now the CIO of the Department of Commerce.With Bahram Ravani taking over as the new chief editor of JCISE, we have begun the process of gradually migrating from eLane to ASME’s Journal Tool. Although the Journal Tool still lacks some functionality available in eLane, the reasons for migration are that this will provide greater visibility to JCISE through ASME websites, set JCISE at par with other Transactions, make it easier to transfer papers between ASME journals and, most importantly, have 24/7 support from ASME’s IT professionals.My tenure as chief editor is ending as it started, with a special issue providing snapshots of each of the technology areas within our scope. In both cases, I put together a wish list of papers and expert groups to co-author the state of art reviews. I had hoped to have every area covered, but some papers did not materialize this time around. Nevertheless, this special issue will be a good reference for most, if not all of the areas JCISE covers. For V1 N1, I invited each of our founding Associate Editors to write state-of-the-art surveys of their fields in collaboration with other experts in their respective areas. This special issue contains survey papers not only in some well-established CIE areas but also in a few emerging fields.Computational methods and information technologies related to engineering product development have come a long way. CAD, CAM, FEA, CFD, VR, Reverse Engineering, Computational Metrology, Optimization, and many other simulation techniques are now pervasive in industry. Even traditional fields, such as thermal science, fluid mechanics, and solid mechanics, have embraced numerical methods and computer visualization. What started on the fringes is now the mainstream. We owe it to the founders of the CED/CIE Division who saw this potential more than 30 years ago. Let us recognize Ali Seireg (Wisconsin), J. Callahan (McDonnell Douglas), V. Tipnis, T. Shoup (Santa Clara), D. Dietrich (Swanson), L. Hulbert (Battelle), E. Heer (NASA), S. Rhode (GM), R. Fulton (Georgia Tech), J.Cokonis (GE), R. Arvikar (Bell Labs), J. Lemon (SDRC), D. Riley (U. Minnesota), and R. Raghavan (Foster Wheeler).A high quality archival journal is extremely important to any research community. A conference alone cannot be sufficient. Conferences, at least in engineering, serve the purpose of quick dissemination of work in progress. Having an archival journal aids the maturation of a research community. Not all conference papers are suitable for archival in a journal. An additional complication in computing and IT is the rapid rate of development and consequent obsolescence of ideas and methods. What then should we archive? There certainly are many techniques in our field that have withstood the test of time. B-Rep solid models, B-splines, and NURBS, regularized Boolean algorithms, Attributed Adjacency Graph based feature recognition, and bipartite graphs for constraint solving are but a few examples. But most research is incremental, and it is important to archive snapshots of major milestones in each area. NURBS did not just come about suddenly. There were B-splines, rational B-splines before the idea of nonuniform knot spacing.JCISE associate editors serve 3 year terms, renewable for an additional 3. In addition to the founding group of AEs, I want to take this opportunity to thank all our current and past AEs. They are the ones that do the bulk of the work and get the credit for maintaining our high quality. I am very grateful to the following individuals: J. Michopoulos, K. Saitou, A. Goel, I. Grosse, K. Law, X. Qian, J. Oliver, S. McMains, S. Gao, A. Fischer, J. Vandenbrande, C. Geiger, Y. Kitamura, C. McMahon, A. Joneja, S. K. Gupta, R. Crawford, K. Lee, J. Corney, N. Dorighi, L. Joskowicz, and S. Callahan.I am sure that our new chief editor, Bahram Ravani, will take JCISE to new heights. My very best wishes to JCISE readers, authors, and reviewers. For me, this has been a labor of love.

In the last years, the field of non-linear Computational Geometry has produced very relevant algorithmic advances, for instance, by adapting to low-degree curved objects techniques dealing with linear primitives. Moreover the introduction of new algorithms and approaches for dealing efficiently with curves and surfaces has shown a considerable impact in fields such as Computer-Aided Design where final users are continuously demanding more efficiency, accuracy, robustness, etc. New approaches for solving geometric problems, coming from Computer-Aided Geometric Design and involving curves and surfaces with a Computational Geometry flavour is the main focus of this special issue. Contributions were asked in areas such as: arrangements of low degree curves and surfaces; Voronoi diagrams and medial axes involving curved ob jects; offset computations and their topology; distance predicates for curves and surfaces; closed formulae for geometric queries involving curves and surfaces; intersection detection for moving curved ob jects; adapting algebraic or geometrical techniques for solving algorithmic problems involving curves and surfaces. This special issue is a direct consequence of the Second International Conference on Mathematical Aspects of Computer and Information Sciences - MACIS 2007 (see http:// www- spiral.lip6.fr/ MACIS2007) held in Paris in December 2007 and where Computational Geometry and Computer Aided Geometric Design were one of the main topics (among other two, Polynomial System Solving and Algorithms and Complexity). Finally six papers (out of eight papers submitted by the March 2009 deadline) were finally accepted. The two papers by C. D'Andrea et al. and I. Z. Emiris et al. deal with the problem of analyzing the Newton polygon of the implicit equation of a rational curve starting from its parameterization: both papers are devoted to study from different viewpoints the properties of the set of monomials appearing in the implicit equation of the considered curve without computing it. The two papers by E. Berberich et al. introduce a new approach to deal with the problem of determining the shape of an arrangement of curves on several classes of parametric surfaces which is then applied to compute, for example, the Minkowski sum of polytopes or the envelope of surfaces. The two papers by D. Lazard and J. Cheng et al. deal with the problem of computing the topology of a semialgebraic set (i.e. a set in $\mathbb{R}^n$ defined by polynomial equations and inequations): the first one shows how to deal with the general case by using the so called Cylindrical Algebraic Decomposition and the second one introduces an extremely fast algorithm computing the topology of a real algebraic plane curve defined implicitely. We would like finally to thank all the reviewers who definitively helped with their work to improve the papers that appear into this special issue.

Welcome to the special issue on selected papers from the ELECO-2013 Conference!, the 8th International Conference on Electrical and Electronics Engineering, held 28–30 November 2013, in Bursa-Turkey. ELECO conferences go back to 1986, when it was initially organized as national ELMEKSEM Electromechanical Conference by the Chamber of Electrical Engineers (EMO) Bursa Branch and upon that success repeated in 1988 and 1993 and 1997. The Bursa Branch has further gone on to organize a series of Electrical and Electronics Engineering Conferences in Bursa. ELECO conferences are organized at international level in odd numbered years and as national conferences in even numbered years, such as ELECO’2013 is the eight international conference which participants coming from various countries, presenting papers from the wide spectrum of electrical and electronics engineering. ELECO 2013 is jointly organized by Uludag University, Bursa; Istanbul Technical University (ITU), Istanbul and the Chamber of Turkish Electrical Engineers (EMO) Bursa Branch. The IEEE Region 8, IEEE Circuits and Systems (CAS) Turkey section and The Scientific and Technological Research Council of Turkey are co-sponsors of ELECO 2013. Taking the broad scope of the technical program, it is probably the largest electrical and electronics engineering conference ever held in Turkey. The scope of the conference covers topics ranging over electric power systems, electrical machines and drives, power electronics, high voltage techniques, electrical materials, electronics, circuits and systems, signal processing, electromagnetics, antennas and propagation, microwave theory, communication systems, mechatronics, control theory, control applications, automation systems, robotics and intelligent control systems. Two hundred and thirty five papers have been submitted for presentation and 138 papers have been accepted. If we look at the contributions with respect to geographical point of view, it is seen that ELECO 2013 contributions are coming from 17 different countries. Selected papers from previous international ELECO Conferences were invited to be published in extended form in special ELECO issues of international journals, under peer review. Three special ELECO issues appeared in the journal Analog Integrated Circuits and Signal Processing containing selected papers from ELECO’2001, ELECO’2007 and ELECO’2011. Furthermore, four special ELECO issues appeared in the journal TJEECS: Turkish Journal of Electrical Engineering and Computer Sciences where selected papers from ELECO’2003, ELECO’2005, ELECO’2007, and ELECO’2009 were published in extended form, respectively. This special issue on selected papers from ELECO’2013 contains extended versions of 12 papers presented at the conference, chosen among 19 recipients of the call for the papers for the special issue. All papers had to undergo the usual ALOG review process before they were finally accepted for this special issue. One of these papers is selected from invited talks given by world-known scientists during the conference. Six papers are selected from the papers presented in Special Session on Advances and New Design Possibilities for Analog Signal Processing. The other five are chosen from regular submitted manuscripts. H. H. Kuntman (&) S. Ozoguz O. Cicekoglu Istanbul Technical University, Istanbul, Turkey e-mail: kuntman@itu.edu.tr

Nonrobustness is a well-known problem in many areas of computational science. Until now, robustness techniques and the construction of robust algorithms have been the province of experts in this field of research. We describe a new C/C++ library (CORE) for robust numeric and geometric computation based on the principles of Exact Geometric Computation (EGC). Through our library, for the first time, any programmer can write robust and efficient algorithms. The Core Library is based on a novel numerical core that is powerful enough to support EGC for algebraic problems. This is coupled with a simple delivery mechanism which transparently extends conventional C/C++ programs into robust codes. We are currently addressing efficiency issues in our library: (a) at the compiler and language level, (b) at the level of incorporating EGC techniques, as well as the (c) the system integration of both (a) and (b). Pilot experimental results are described. The basic library is availableathttp://cs.nyu.edu/exact/core/andthe C++-to-C compiler is under development.

One of the most striking features of mathematics is the fact that we are much more certain about the mathematical knowledge we have than about what mathematical knowledge is knowledge of. Are numbers, sets, functions and groups physical entities of some kind? Are they objectively existing objects in some non-physical, mathematical realm? Are they ideas that are present only in the mind? Or do mathematical truths not involve referents of any kind? It is these kinds of questions that have encouraged philosophers and mathematicians alike to focus their attention on issues in the philosophy of mathematics. Over the centuries, a number of reasonably well-defined positions about the nature of mathematics have been developed and it is these positions (both historical and current) that are surveyed in the current volume. Traditional theories (Platonism, Aristotelianism, and Kantianism), as well as dominant modern theories (logicism, formalism, constructivism, fictionalism, etc.), are all analyzed and evaluated. Leading-edge research in related fields (set theory, computability theory, probability theory, and paraconsistency) is also discussed. The result is a handbook that not only provides a comprehensive overview of recent developments but that also serves as an indispensable resource for anyone wanting to learn about current developments in the philosophy of mathematics. Features of this title include: comprehensive coverage of all main theories in the philosophy of mathematics; clearly written expositions of fundamental ideas and concepts; and, definitive discussions by leading researchers in the field. Summaries of leading-edge research in related fields (set theory, computability theory, probability theory, and paraconsistency) are also included.

Notes from the Editors: Restructuring the Journal of Operations Management

The International Institute for FRP in Construction (IIFC) was formed in 2003 with a mission to advance the understanding and application of fiber–reinforced polymer (FRP) composites in civil infrastructure. Since 2005, IIFC has enjoyed a fruitful association with ASCE via co-sponsorship of the Journal of Composites for Construction (JCC). Therefore, it is fitting that this present JCC issue commemorates the 10th anniversary of IIFC. This is the third special IIFC issue published by JCC; the first two issues were in April 2007 (“Recent International Advancements in FRP Research and Application in Construction”) and April 2011 (“In Honor of Professor Urs Meier”). The flagship events of IIFC are undoubtedly its biannual worldwide and Asia-Pacific regional conference series, which are known as FRP Composites in Civil Engineering (CICE) and Asia-Pacific Conference on FRP in Structures (APFIS), respectively. These conferences are held in alternating years at differing locations around the world: CICE in 2001 (Hong Kong), 2004 (Adelaide), 2006 (Miami), 2008 (Zurich), 2010 (Beijing), and 2012 (Rome); and APFIS in 2007 (Hong Kong), 2009 (Seoul), 2012 (Sapporo), and 2013 (Melbourne). CICE 2014 will be held in Vancouver and CICE 2016 in Hong Kong.This special issue of JCC has been timed for release prior to CICE 2014. IIFC also co-sponsors other international conference series and workshops. To better disseminate knowledge to the wider community, IIFC makes the proceedings of most IIFC official and supported events available on its website (http://www.iifc-hq.org) for free download. IIFC publishes a newsletter and all copies are also held on the IIFC website. The newsletter commenced in 1993, and for its first 10 years, was known as FRP International. IIFC also runs several working groups that offer tangible benefits such as educational resources, state-of-the-art reports, conference special sessions, and journal special issues. IIFC recognizes excellence in the form of several awards, namely, IIFC Medal, Distinguished Young Researcher Award, President’s Award, Lifetime Achievement Award, conference best paper awards, and IIFC fellowships. The IIFC website contains lists of all award recipients over the years, in addition to far more information than can be contained in this editorial. IIFC is a dynamic organization that has been positively influenced by numerous individuals over the years. It is governed by an Executive Committee, which is overseen by an Advisory Committee. The Council is populated by up to 40 elected leading figures in the field from around the world, plus members of the Advisory Committee. At present, 21 countries are represented on these three committees and several of these leading figures also serve on the Editorial Board of JCC. This special issue contains 18 invited papers contributed by members of these committees and their collaborators, addressing a diverse range of topics that are representative of the breadth of activity in the field. More specifically, the papers are of an experimental, analytical, and numerical nature and address: • FRP for strengthening concrete; namely, prestressed FRP plates, strips, and rods (two papers), confinement (one paper), FRP patch anchors (one paper), limits to the application of FRP for repair (one paper), near-surface mounted FRP (one paper), cementitious bonding agents (three papers), and large strain capacity FRP (one paper); • FRP for strengthening timber (one paper), steel (one paper), and masonry (one paper) construction materials; and • FRP for new construction; namely, hybrid FRP tendons (one paper), FRP bars (two papers), FRP beams (one paper), and stay-in-place structural forms (one paper). There is plenty of work still to be done in the field. In particular, more systematic and in-depth research is required on the long-term behavior of both FRP structures and FRP strengthened structures to substantiate the common claim that such structures have superior durability over other structures. Innovative combinations of FRP with either traditional construction materials or new materials to produce new structural members and forms will have an important role in designing the next generation of high-performance and sustainable structures. There is no doubt that the conversion of research findings into workable design guidelines and standards for use by design engineers is critical in widening the applications of FRP in civil construction. The contributions of numerous individuals are acknowledged in the preparation of this special issue. The authors of the papers in this issue are thanked for preparing high-quality manuscripts. Professor Charles E. Bakis, Editor-in-Chief of JCC, is thanked for handling the paper review process and ensuring maintenance of the high JCC standard. Professor Bakis is also supported by Ms. Renee Lindenberg and a large team of reviewers; their contributions are all acknowledged. The idea of an IIFC 10th anniversary special issue was positively received by Professor Lawrence C. Bank, IIFC President, and by the members of the Executive Committee following discussions after CICE 2012. For that, they are all thanked for their support. Finally, all members of IIFC, past and present, are thanked for their various contributions over the years, which have enabled IIFC to move into its second decade on a sound and positive footing.

Special Issue on the 40th Anniversary of University of Macau

“Security” is such a general concept that, on the one hand, it is omnipresent in all fields of historical research; on the other hand, a closer look reveals that there seems not to exist a real specialized sub-discipline or field that bears this title. While in political sciences, criminology, sociology and jurisprudence, and especially in the field of international relations, security studies is a well established and broad field of research, history has not yet established a corresponding field. This special issue about “Security and Epochal Frontiers” shows that important contemporaneous changes in concept and practices of “security production” after the end of the Cold War (the emergence of “extended, comprehensive, human security”, the fading away of the border between internal and external security) have caused our historical perception of “security” to change massively and historiography to respond to this challenge.

The Seventh International Symposium on Neural Networks (ISNN 2010) was held on June 6–9, 2010 in Shanghai, China. The ISNN 2010 was a great success and provided a high-level international forum for scientists and engineers to present the latest research in neural networks, computational intelligence, cognitive systems, and related fields. To highlight the success of this conference, we edited this special issue for Cognitive Computation. We chose nine papers from over 591 papers submitted to ISNN 2010, which reflect the high quality of the presentations at the conference while capturing the spirit of our theme, ‘‘Advances in Computational Intelligence and Applications,’’ for this special issue. Our goal for this special issue is to present the latest research developments in computational intelligence with a focus on cognitive computation and their applications across a wide range of domains. Over the past decades, we have witnessed tremendous interest and developments in all aspects of computational intelligence research, ranging from both theoretical foundations, principles, to practical applications in different domains. To reflect a flavor of recent research activities in the community, we carefully selected these nine papers for this special issue. The selected papers can be organized into the following four coherent sections. The first section is directly related to neural network models and applications. The paper by Deng presents a new control strategy for the chaotic neural network, in which the refractoriness is tuned by using feedback control based on online averaging of network states. Simulation results demonstrate that the proposed model can achieve favorable performance in handling noisy, incomplete, and composite patterns, while also achieving either enhanced or comparable memory capacity compared with the classic Hopfield net and other chaotic neural network models. In the other paper, Gluge et al. discuss recurrent networks for implicit learning of temporal sequences, a very important area to understand high-level cognitive intelligence. The authors propose a recurrent network with backpropagation training algorithm that is adapted to the reinforcement learning scheme. The simulation results fit quantitatively as well as qualitatively to the behavioral results, suggesting the role of temporal context in associative learning scenarios. The second section is related to language processing and understanding, an important topic in cognitive science and computational intelligence. The paper by Murata et al. investigates the maximum entropy (ME) approach for natural language processing (NLP) problems including machine translation and information extraction. Comparative studies of the proposed approach with the existing techniques are illustrated in this paper. In related work to this field, the paper by Kaznatcheev investigates connectionist models on the interplay of nouns and pronouns in personal pronoun acquisition, a very interesting and important problem in psychology. For instance, the author discusses the learning in the shifting reference situation for children. It is reported that learning of two different noun-and-pronoun addressee patterns is consistent with Z.

Materials processing, an important branch of materials science and engineering, converts raw materials into practical materials and their products for technological applications. These processing methods are developed to satisfy the service needs based on sound scientific theory. Different processing conditions confer practical materials with controllable microstructures and thus specific mechanical and functional properties. Therefore, developing novel processing methods and exploring the interaction between microstructure and properties under different processing conditions have received much attention in the scientific community, especially in recent years. With the rapid progress of modern science and technology, novel materials processing technologies involve the coupling of multi-physics field, including temperature, stress, electric field, magnetic field, gravity, ultrasonic field, microwave field, etc. The multi-physics field can give rise to some unique thermodynamic and kinetic behaviors during materials processing and thus lead to novel microstructures, such as refined grains, bimodal/multi-modal microstructure, heterogeneous microstructure, etc. Thus, the field-assisted materials processing technology is considered a revolutionary method to fabricate competitive high-performance practical materials.

Mastering challenging times and looking with optimism into the future

Proteomics in Marine Organisms.

The papers in this volume were presented at the 19th Annual ACM Symposium on Computational Geometry, held June 8-10, in San Diego, California (USA), as part of the Federated Computer Research Conference (FCRC 2003). The symposium included research papers of both an applied and a theoretical nature, as well as a video review.The symposium was sponsored by SIGACT and SIGGRAPH, two of the Special Interest Groups of the Association for Computing Machinery (ACM).This year the symposium received 118 submissions in response to the Call for Papers. The overall quality of the submissions was quite high, and the committee had a hard time limiting the selection for presentation at the symposium and inclusion in these proceedings to 42 papers. The papers generally represent preliminary results of ongoing research. It is expected that most papers will eventually appear in a more polished and complete form in refereed journals.The program committee is very grateful to the people who helped review the submissions. They often gave substantial and specific comments, many of which were forwarded to the authors to help them improve their papers. These reviewers are listed on page x.In addition to the paper submissions, there we 12 submissions in response to the Call for Videos and Multimedia, of which 9 were accepted. For the first time, it was not only possible to submit video, but also other forms of multimedia such as applets and PowerPoint animations. These proceedings contain a short description of each of the accepted contributions. Furthermore, the accepted contributions were collected onto a DVD, which was distributed among the attendees of the symposium.
