The future of IPTV

As more and more content migrates to the Internet, “personal” video choices are becoming the norm not the exception. The impact of Internet content and IP-based video distribution is still difficult to evaluate. However, there is obviously no turning back as this content pervades the home and the community. Driven in large part by the near-ubiquitous IP-based communication services, the TV experience has been extended over the years to embrace many of the same ancillary services provided by web applications. This new TV promises to deliver a world of content and services to “any device, anywhere, anytime.” This article addresses the architecture, the value chain and the technical and business challenges of implementing this new connected mobile and social TV experience. To put the architecture into a context, this article also presents a use case of the distributed community Digital Video Recorder (DVR) as an implementation of this vision.     

The future of phishing

This article examines how attackers are likely to respond to the current move towards 2-factor authentication as a defence against phishing scams, and describes an alternative approach, available today, that provides a longer-term solution.In recent months, newspaper and television reports have highlighted how highly-organized criminal gangs are launching large-scale, carefully planned attacks against high-street banks and other services, both in the UK and overseas. These so-called ‘phishing’ attacks begin with an email. Appearing to come from the bank, it leads the recipient to a convincing Web page, at which point he is tricked into entering his username and password.     

The future of control

The development of control is briefly reviewed. It is suggested that ‘modern’ control has two aspects: a mathematical investigation of basic properties of dynamical systems, and the development of algorithmic methods of synthesis. Reasons are given for believing that the first of these will have more enduring value than the second. Algorithmic methods which try to eliminate the skill of the designer are contrasted with alternative methods which accept his skill and make it more productive. It is finally suggested that the impact of computers upon industry may give the opportunity for a similar development of production methods which accept and enhance the skill of manual workers.     

The future of microprocessors

Before making statements about microprocessor trends 10 years out-Micro 2006-it might be useful to revisit our past statements (Gelsinger et al. (1989, 1991)) about the microprocessor of today and the microprocessor of 2000. Then we can see where we have been right and where wrong. This retrospective will reveal important trends that promise to give some insight into the microprocessor of the next decade.     

The future of targeted peptidomics

Targeted MS is becoming increasingly important for sensitive and specific quantitative detection of proteins and respective PTMs. In this article, Ceglarek et al. [Proteomics Clin. Appl. 2013, 7, 794–801] present an LC-MS-based method for simultaneous quantitation of seven apolipoproteins in serum specimens. The assay fulfills many necessities of routine diagnostic applications, namely, low cost, high throughput, and good reproducibility. We anticipate that validation of new biomarkers will speed up with this technology and the palette of laboratory-based diagnostic tools will hopefully be augmented significantly in the near future.     

The future of online therapy

The digital world, and the Internet in particular, have a significant impact on almost all aspects of our lives. The realm of psychotherapy is an area in which the influence of the Internet is growing rapidly. This paper suggests a model for comprehensive online therapy online with a therapist at its center. We start by explaining the main components of both traditional therapy and online therapy. We discuss the principal criticisms leveled against online therapy and assess the efficacy of various responses. The paper moves on to explain the advantages of online therapy, focusing on the unique aspects of this approach. The paper proposes that online therapy should exploit other online resources, including online techniques for information gathering. This is true both in the therapeutic session and outside of it. In addition, the paper suggests that therapists incorporate online role play, online CBT and intervention techniques using the smartphone. All of these tools are suggested as important components in a process of comprehensive therapy run by a therapist working online.     

The future of PID control

This paper presents the state of the art of PID control and reflects on its future. Particular issues discussed include specifications, stability, design, applications, and performance of PID control. The paper ends with a discussion of alternatives to PID and its future.     

The future of optimization technology

Technology for combinatorial optimization is rapidly changing, and as the size and scope of problems that can be solved steadily increases, the complexity of the underlying technology is growing. We foresee a huge demand for both the simplification of use of combinatorial optimization technology (so called “model and run” capabilities), as well as increasing need for the ability to quickly build complex hybrid solutions. These demands will place new emphasis on universal modeling languages and model transformation capabilities, as well as flexible and high level ways of specifying hybrid solutions. These changes put constraint programming in an ideal position since: constraint programming has the most high-level view of problems to begin with so we can ease modeling difficulties; and since constraint programming is an integrative technology, we have already spent considerable effort in making different solving technologies work together seamlessly. In this position paper we outline some of the key challenges and important research directions we foresee for optimization technology,     

The future of systems research

After 20 years in academia and the Silicon Valley, the new Provost of Stanford University calls for a shift in focus for systems research. Performance-long the centerpiece-needs to share the spotlight with availability, maintainability, and other qualities. Although performance increases over the past 15 years have been truly amazing, it will be hard to continue these trends by sticking to the basically evolutionary path that the research community is currently on. The author advocates a more evolutionary approach to systems problems and thinks the approach needs to be more integrated. Researchers need to think about hardware and software as a continuum, not as separate parts. He sees society on the threshold of a “post PC” era, in which computing is ubiquitous, and everyone will use information services and everyday utilities. When everyone starts using these systems, guess what? They expect them to work and to be easy to use. So this era will drive system design toward greater availability, maintainability, and scalability, which will require a real refocusing of current research directions     

The future of object technology

In the future, object technology will not be confined to a niche. Objects will be pervasive; very little serious software will not be object-oriented at least in some way in 1998 and beyond. Object technology isn't a matter of fashion. It's simply that no-one really knows how to tackle the kind of sophisticated systems that our users now want, without using object technology. It's also that no one has found anything better. Since object technology came into prominence a decade ago, pundits have at various times predicted its demise, with the inevitable periodic announcements of the so-called “Object Winter”-an allusion to the “AI Winter” that froze the spread of artificial intelligence in the late 1970s-but winter has not come, and all the signs indicate that spring will continue     

The future of the factory

The basic driving force that will determine the future of the factory is likely to be the margin of profitability. In rapidly changing high technology industry the advances in product design will enable them to increase the margin of profitability through increases in the selling price, whereas in more traditional industries it must be obtained by decreasing the total manufacturing cost. Among the most important factors that will affect the manufacturing cost are, in order of importance, information management (which determines the indirect cost), the materials cost, the direct labor cost, and the capital cost. In order to reduce the direct cost, computers will be used extensively to integrate the entire manufacturing system, ranging from design to manufacturing processes to quality control. For computer-integrated manufacturing systems to be effective, more intelligent machines should be developed to minimize the information flow. However, the single most important thing that will always have the most significant effect on margin of profitability, and thus on the factory of the future, will be the ability to make rational decisions during the synthesis of processes and products. The yield of electronic component fabrication processes, the efficiency of mechanical products, the productivity of a factory, and the portability and efficiency of software can be improved when design decisions are evaluated using the synthesis axioms. Therefore, the factory of the future should not only involve computer-integrated manufacturing systems, but also the computers should be provided with intelligence so as to enable them to make correct decisions and aid the decision makers at all levels of industrial hierarchy.     

The future of computer-aided innovation

A new category of tools known as CAI (computer-aided innovation) is an emerging domain in the array of computer-aided technologies. CAI has been growing as a response to greater industry demands for reliability in new products. Some initial CAI ideas and concepts focused on assisting product designers in the early stage of the design process, but now a more comprehensive vision conceives CAI systems as beginning at the fuzzy front end of perceiving business opportunities and customer demands, then continuing during the creative stage in developing inventions and, further on, providing help up to the point of turning inventions into successful innovations in the marketplace. CAI methods and tools are partially inspired by Innovation Theories, such as TRIZ, QFD (Quality Function Development), Axiomatic Design, Synectics, General Theory of Innovation, Mind Mapping, Brain Storming, Lateral Thinking, and Kansei Engineering, among others. The goal of these new CAI tools under development is to assist innovators, inventors, designers, process developers and managers in their creative performance, with the expectation of changes in paradigms through the use of this new category of software tools. CAI, therefore, stands out as a departure from the usual trends. The latest approaches are presented and analyzed to derive conclusions regarding the present status and the future of these emerging tools.     

The future of European cohesion

In its broadest sense, cohesion is an ultimate goal for Europe. In a study about long term future scenarios for Europe it appears that deepening of the integration process may induce decreasing cohesion, unless measures are taken to promote regional diversity as a vector of development. The widening of Europe also raises threats to cohesion, but a well prepared scenario for a Development Belt surrounding the EC may positively enhance the cohesion process.
