...the tablet and IPAD making computing easy and eliminating the need to sit in front of a desktop or lug around storage mediums such as cds. Mark Weiser, most often referred to as the father of ubiquitous computing (ubicomp), coined the term in 1988. Ubiquitous means to exist everywhere at the same time or to be constant. His forward thinking brought about the possibility to compute on the go and from nearly anywhere. Innovation news daily provides readers with insight on innovative technologies and inventions that shaped ubiquitous computing and many other technologies. In an article entitled “In the Future, Computing is (Cunningly) Constant”, the details of ubiquitous computing are outlined. It also features contributing components and the effect of such an evolution in lifestyles and business. Ubiquitous computing has been “under construction” for more than two decades. According to the article, it originated in a Xerox PARC research lab where the father of ubicomp (Weiser) worked. Innovation news refers to it as a state in which mobile devices such as the IPAD combine forces with high speed internet connections, Google docs, and cloud computing to reduce the need for the computer in the computing process. Along with eliminating the need for the computer, ubicomp in the years to come is expected to save the consumer space, on the desk and the headache of trying to find a computer and systems that work for your lifestyle. Consumers will shop for data systems such as cloud...

...Cue-based Networking using Wireless Sensor Networks: A Video-over-IP Application Yeonsik Jeong ∗ School †‡ , Sriram Lakshmanan∗ , Sandeep Kakumanu∗ , and Raghupathy Sivakumar∗ † Department of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, Georgia of Multimedia System Engineering, SungKongHoe University, Seoul, Korea Email: {ysjeong, sriram, ksandeep, siva}@ece.gatech.edu, ysjeong@mail.skhu.ac.kr Abstract—In this paper we present a new approach called cue-based networking that uses hints or cues about the physical environment to optimize networked application behavior. We define the notion of cues and describe how cues can be obtained using a wireless sensor network as the underlying platform. We identify both the research and system challenges that need to be addressed to realize benefits of the approach under a target application of video delivery over IP networks. In the process, we identify a key challenge of wireless sensor networks, namely the timeliness-robustness tradeoff. We design an adaptive algorithm that balances this tradeoff satisfying both timeliness and robustness requirements. Through an implementation of the video delivery application using the proposed algorithm in a real home environment, we highlight the practical benefits of the proposed approach. I. I NTRODUCTION Optimizing the behavior of application and network protocols has been a continuing endeavor since the origins of the Internet. In this paper we present...

...HC: Human-Computer Interaction Human–computer interaction (HCI) is concerned with designing the interaction between people and computers and the construction of interfaces to afford this. Interaction between users and computational artefacts occurs at an interface which includes both software and hardware. Interface design impacts the software life-cycle in that it should occur early; the design and implementation of core functionality can influence the user interface – for better or worse. Because it deals with people as well as computers, as a knowledge area HCI draws on a variety of disciplinary traditions including psychology, computer science, product design, anthropology and engineering. HC: Human Computer Interaction (4 Core-Tier1 hours, 4 Core-Tier2 hours) Core-Tier1 hours HCI: Foundations HCI: Designing Interaction HCI: Programming Interactive Systems HCI: User-cantered design & testing HCI: Design for non-Mouse interfaces HCI: Collaboration & communication HCI: Statistical Methods for HCI HCI: Human factors & security HCI: Design-oriented HCI HCI: Mixed, Augmented and Virtual Reality 4 4 Core-Tier2 hours Includes Electives N N HC/Foundations [4 Core-Tier1 hours, 0 Core-Tier2 hours] Motivation: For end-users, the interface is the system.

...Reach Out and Touch: Using NFC and 2D Barcodes for Service Discovery and Interaction with Mobile Devices Eamonn O’Neill1, Peter Thompson2, Stavros Garzonis1, and Andrew Warr1 1 Department of Computer Science, University of Bath, UK, BA2 7AY {eamonn, s.garzonis, cspaw}@cs.bath.ac.uk http://www.cityware.org.uk 2 Vodafone Group R&D, Newbury, UK, RG14 2FN peter.thompson@vodafone.com Abstract. We investigate the use of 2 tagging technologies: Near Field Communication (NFC) and 2-dimensional barcodes. Our investigation combined a field trial and interview based study with an experimental evaluation. The field trial focused on users’ experience of the usability of NFC for a range of trial services, users’ perceptions of NFC use in their daily life context, and users’ suggestions for potential applications of NFC. The tags were embedded in a variety of postcards, table-top signs and posters. The experimental evaluation compared the ease of use of NFC and 2D barcodes, operationalised in terms of time taken to read a specified sequence of tags on posters. We found that for untrained users the 2D barcodes were quicker to use than the NFC tags but that training significantly improved users’ performance with the NFC tags while having no effect on their performance with the barcodes. 1 Introduction The use of ambient tags read by mobile devices presents new possibilities for service discovery and user interaction. Service discovery is an increasingly important issue as we move towards...

...Artificial Intelligence and Software Engineering: Status and Future Trends Jörg Rech, Klaus-Dieter Althoff The disciplines of Artificial Intelligence and Software Engineering have many commonalities. Both deal with modeling real world objects from the real world like business processes, expert knowledge, or process models. This article gives a short overview about these disciplines and describes some current research topics against the background of common points of contact. 1 Introduction During the last decades the disciplines of Artificial Intelligence (AI) and Software Engineering (SE) have developed separately without much exchange of research results. In AI we researched techniques for the computations that made it possible to perceive, reason, and act. Research in SE was concerned with supporting human beings to develop better software faster. Today, several research directions of both disciplines come closer together and are beginning to build new research areas. Software Agents play an important role as research objects in Distributed AI (DAI) as well as in agentoriented software engineering (AOSE). Knowledge-Based Systems (KBS) are being investigated for learning software organizations (LSO) as well as knowledge engineering. Ambient Intelligence (AmI) is a new research area for distributed, non-intrusive, and intelligent software systems both from the direction of how to build these systems as well as how to design the collaboration between ambient systems.

...Automation is the use of control systems and information technologies to reduce the need for human work in the production of goods and services. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the muscular requirements of work, automation greatly decreases the need for human sensory and mental requirements as well. Automation plays an increasingly important role in the world economy and in daily experience. Automation has had a notable impact in a wide range of industries beyond manufacturing (where it began). Once-ubiquitous telephone operators have been replaced largely by automated telephone switchboards and answering machines. Medical processes such as primary screening in electrocardiography or radiography and laboratory analysis of human genes, sera, cells, and tissues are carried out at much greater speed and accuracy by automated systems. Automated teller machines have reduced the need for bank visits to obtain cash and carry out transactions. In general, automation has been responsible for the shift in the world economy from industrial jobs to service jobs in the 20th and 21st centuries.[1] Movable type is the system of printing and typography that uses movable components to reproduce the elements of a document (usually individual letters or punctuation). The world's first known movable-type system for printing was created in China around 1040 A.D. by Bi...

...©2010 International Journal of Computer Applications (0975 - 8887) Volume 1 – No. 17 Routing Approaches in Delay Tolerant Networks: A Survey R. J. D'Souza National Institute of Technology Karnataka, Surathkal, India Johny Jose National Institute of Technology Karnataka, Surathkal, India ABSTRACT Delay Tolerant Networks (DTNs) have evolved from Mobile Ad Hoc Networks (MANET). It is a network, where contemporaneous connectivity among all nodes doesn’t exist. This leads to the problem of how to route a packet from one node to another, in such a network. This problem becomes more complex, when the node mobility also is considered. The researchers have attempted to address this issue for over a decade. They have found that communication is possible in such a challenged network. The design of routing protocol for such networks is an important issue. This work surveys the literature and classifies the various routing approaches. discontinuity in the network. There are also methods that have employed additional mobile nodes, to provide better message delivery. Researchers are even exploring how the social interaction of humans can be utilized for routing in a DTN. This survey has made an extensive study of the various routing strategies taken by the researchers in the past few years. We have classified them based on the type of knowledge used for routing. 2. FLOODING BASED APPROACHES Knowledge about the network helps in deciding the best next hop. It can happen that the...

Zaki, Communications of the ACM, 56(10), Oct. 2013, pp.74-83 An Evolution of Computer Science Research∗ Apirak Hoonlor, Boleslaw K. Szymanski, Mohammed J. Zaki, and James Thompson Abstract Over the past two decades, Computer Science (CS) has continued to grow as a research field. There are several studies that examine trends and emerging topics in CS research or the impact of papers on the field. In contrast, in this article, we take a closer look at the entire CS research in the past two decades by analyzing the data on publications in the ACM Digital Library and IEEE Xplore, and the grants awarded by the National Science Foundation (NSF). We identify trends, bursty topics, and interesting inter-relationships between NSF awards and CS publications, finding, for example, that if an uncommonly high frequency of a specific topic is observed in publications, the funding for this topic is usually increased. We also analyze CS researchers and communities, finding that only a small fraction of authors attribute their work to the same research area for a long period of time, reflecting for instance the emphasis on novelty (use of new keywords) and typical academic research teams (with core faculty and more rapid turnover of students and postdocs). Finally, our work highlights the dynamic research landscape in CS, with its focus constantly ...
