Sign-in-time Based Info-communication System for Collecting Selective Waste

In the field of municipal waste, expanding cities and growing trend of the population have increasing and problematic effects. Improperly emptied containers jeopardize the possibility of the development of cleaner and more liveable city. Directly occurring problems can be the environmental and road-safety aspects during reaching the containers. Through the application of modern technologies, there are opportunities to apply sign-in-time frequency-based communication. This leads not only to the optimization of the collection route but also to the reduction of the above mentioned problems and problematic effects.

Special Issue on CogInfoCom 2012

Cognitive infocommunications (CogInfoCom) investigates connections between the cognitive sciences and different areas of infocommunications. CogInfoCom also focuses on engineering application fields integrating related scientific areas and results. Cognitive infocommunications systems involve hardware and software components that collect and store information and enable users to interact with this information. Besides communication security, considerations include the amount of stored information, which may be huge. This means that there is a need for algorithms and solutions that store and process data effectively. The CogInfoCom field presents a number of motivational challenges requiring active deep research, implementation, integration and measurement. This special issue focuses on the Cognitive Mobile Applications and Services track of the 3rd IEEE International Conference on Cognitive Infocommunications (CogInfoComf12). Mobile phones and tablets are now everyday tools that enable users to easily connect to the Internet, download social content, find interesting places, etc. Mobile technology has become one of the most important fields in the IT industry just as Web technology was 10-15 years ago. Mobile phones and tablets use sensors and interfaces like accelerometers, cameras, GPS, and thermometers that monitor and enable easier interaction with the real world. Agents hosted by mobile devices that learn from sensor-originated information also support individual applications and complex systems. This special issue focuses on the cognitive capabilities of mobile phones, the various agents that mobile devices host, and how they can be applied efficiently in applications and services including social aspects of mobile solutions. Papers from the conference cover mobile controlled environments, mobile-supported learning, augmented reality, energy efficiency and communication techniques. We thank the authors for submitting their papers to CogInfoCom as a venue for presenting their findings. We are also grateful to program committee members and reviewers for their efforts in making the conference and the special issue possible. We feel that these papers will provide readers with interesting and valuable results from the field of cognitive infocommunications.

Special issue on multimodal interfaces in cognitive infocommunication systems

Humans and the infocommunications network surrounding them are merging together at various levels, ranging from the level of interactions with personal devices to the highest level of sensing collective behaviors such as mass movements, mass habits etc. Consequently, humans and infocommunications will soon coexist as an entangled web, resulting in an augmentation and merging of both natural and artificial cognitive capabilities. This process of merging is occurring today, and is expected to gain further impact in the near future. Cognitive infocommunications (CogInfoCom) is an interdisciplinary field that aims to reflect on this process of merging by investigating links between the research areas of infocommunications and the cognitive sciences, as well as the various engineering applications that have emerged as the synergic combination of these sciences. Given the interdisciplinary background of CogInfoCom, many aspects of the synergies behind it can be considered. The papers in this special issue all focus on some aspect of multimodal interfaces in the context of infocommunication systems that enable enhanced cognitive capabilities through the merging of the natural and artificial. Papers range from the more theoretical to those which introduce practical applications. Several papers address multi-modal aspects of human speech. The paper by A. Abuczki focuses on a multi-modal corpus based approach to modeling cognitive, information and interactional states behind speech interactions, basedon a set of discoursemarkers and hand-based gestures.

Functioning quality and effectiveness of polymodal infocommunicational systems

Abandoning traditional principles of separation of transmitted information on services for polymodal presentation of information requires development of a new constructive theory of building polymodal infocommunication systems. One of its cornerstones is the quantitative research of the degree of the achievement of the purpose of such systems and subscriber terminals’ participation share in this result. This paper presents an approach to evaluation of polymodal systems effectiveness on the basis of the prime cost index.

Basic channels of interpersonal communication and their projection on the infocommunications systems

Multimodality of traditional interpersonal communications points to the purposefulness of using the polymodal dialogue in the process of communicative interaction of infocommunications subscribers. The creation of the polymodal communication systems became possible due to the development of cognitive science and current results in the design area of multimodal interfaces interaction. Application of the existing and expected outcome of signal processing tasks of different modalities in the synthesis of polymodal systems will provide all parties to communicate and their further intellectualization will allow us to approach the infocommunicational interaction of subscribers to the traditional interpersonal communication.

METHOD OF INCREASE OF EFFICIENCY OF FINISHING VIDEO INFORMATION ON THE BASIS OF CODING OF THE PREDICTED FRAMES

It is shown that the crucial role on efficiency of functioning of transport, namely quality of rendering of services on transportations of passengers and loads, is rendered by systems of objective monitoring. The perspective which is dictated by existence of a contradiction comes to light: on the one hand this requirement concerning increase of efficiency and reliability of provision of video information that carries to increase in their volumes, and on the other hand limited carrying capacities and high-speed performance of remote sites of collection of video information that leads to the limited productivity of a technological component. Reasons for option of increase of a compression ratio of a vi-deoinformatsionny flow in infocommunication systems in the conditions of support of the given reliability of information on the basis of abbreviation of temporal redundance on the basis of detection of interframe apertures are carried out. Principal components of development of technology of coding of a packet of the predicted frames on the basis of formation of a code are explained to positional numbers. Analytical expressions for an assessment of the maximum quantity of binary places on representation of a packet of the predicted frames are built.

Design procedure for info-communication system with the maximum throughput

The problem of self–similarity in various areas of science and technology has interested researchers for a long time. Packet losses result in an additional network traffic and, finally, ”congestions”. At high–speed of data transfer packet losses, expressed in portions of a per cent, lead to considerable information losses. It has been shown in numerous papers devoted to the research of network traffic that the abovementioned phenomena are related to the properties of the traffic self–similarity which is mainly caused by the TCP protocol behaviour. However to date models have not been offered which adequately describe the behaviour of the communication networks of information systems and which allow to apply the whole arsenal of classic methods of analyzing nonlinear dynamic systems. The paper suggests a new approach to analyzing the communication network behaviour of information systems with TCP protocol – considering them as nonlinear dynamic systems manifesting chaotic properties at certain values of parameters. Phase portrait of the system under study are built, Lyapunov exponents for different values of the main system parameters are calculated. Recommendations on designing and operating high-speed optical communication networks of information systems are suggested.

Method reverse encoding structural gravimetric numbers for decline bit rate video stream

Presently practically all technology of video information services grant do with the preliminary decline of video-stream speed. For this purpose technologies of images compression are integrated in the info-communication systems. The existent compression degrees at video pictures possible quality do not provide the required bit speeds. A problem, conditioned the insufficient carrying capacity of tele-communication networks, and its lag from constantly growing’s intensities of video traffic, shows up as a result. As a result necessary bit speed is arrived at due to the loss of video information resource integrity. Modernization of network physical basis presents by itself difficult structurally technical process, and requires enormous investments and time. Therefore overcoming of the folded disbalance between bit speed and carrying capacity of network conducted on the basis of images compression technology perfection. In the article examined the stages of creation of the modified position coding of binary elements, being based on forming of code (since junior elements and realization of cross order of accordance between the number elements and by the elements of series lengths array column). A ground is conducted: exceptions of out-of-control losses of information about the binary objects of transforms binary description; reductions of service information content; declines of operations amount for technology coding realization. In the article developed recurrent reversible even coding of the extended position structural-weight numbers of variable length, being based on the rule of elements selection for number expansion.

Nonclassical interference between independent intrinsically pure single photons at telecommunication wavelength

We demonstrate a Hong-Ou-Mandel interference between two independent, intrinsically pure, heralded single photons from spontaneous parametric down-conversion (SPDC) at telecommunication wavelength. A visibility of $85.5\ifmmode\pm\else\textpm\fi{}8.3%$ was achieved without using any bandpass filter. Thanks to the group-velocity-matched SPDC and superconducting nanowire single-photon detectors (SNSPDs), the fourfold coincidence counts are one order higher than that in the previous experiments. The combination of bright single-photon sources and SNSPDs is a crucial step for future practical quantum infocommunication systems at telecommunication wavelength.
