Networked devices are often equipped with multiple interfaces. Legacy routing and transport protocols only support the transport of data over a single interface resp. paths. This tutorial discusses extensions for IP and TCP in order to support multiple interfaces. Multihoming and mobility management allow the simultaneous usage of interfaces by independent application data flows, while multipath transport...
Interviews were undertaken with 26 highly experienced conceptual modelers to determine how they undertook conceptual modeling in practice. Major types of cognitive states and events experienced by the conceptual modelers, as manifested in typed transcripts of the interviews, were then identified and coded. Based on the codes and the interview transcripts, a descriptive, process-oriented theory of...
A new method for efficiently mapping three dimensional environments from a platform carrying a single calibrated camera, and simultaneously localizing the platform within this map is presented in this paper. This is the Monocular SLAM problem in robotics, which is equivalent to the problem of extracting Structure from Motion (SFM) in computer vision. A novel formulation of Monocular SLAM which exploits...
With the massive amount of crime data generated daily, this has put law enforcement under intensive stress. This means that law enforcement has to compete against the time to solve crime. In addition, the focus of crime investigation has been expanded from the ability to catch the criminals towards the ability to act before a crime happens (i.e pre-crime). Given such situation, creation of crime profiles...
In this paper a digital controller has been designed and implemented on field programmable gate array (FPGA) to generate the trigger pulses for a trapezoidal modulated cycloinverter using hardware description language. Trigger requirements are obtained for single-phase centre tapped transformer configuration. With successively improving reliability and performance of digital controllers, the digital...
High dimensional visual features and multimodal based search systems are popular due to their visual retrieval accuracy. But high dimensionality and multimodality negatively affect efficiency and computational complexity. This paper brings the performance advantages of low dimensional visual feature called Compacted Dither Pattern Code (CDPC). CDPC is accompanied with texel properties, spatial colour...
Monitoring the ECG (Electrocardiogram) of patients with cardiac disorder is of paramount importance since they may undergo cardiac arrhythmias even without noticing it. Majority of existing devices for this purpose are only capable of recording ECG of patients which are analyzed later on by cardiologists. This paper presents a new system developed to continuously monitor the ECG of patients and analyze...
Research in the areas of localization, mapping and path planning for single mobile robots has been carried out extensively. Nevertheless, relatively little of its work is applied to multiple robot systems. Moreover, when these robots coexist with human, complex and unpredictable human environments make the above navigational tasks even more challenging. To address this problem we propose intelligent...
Lack of emotional support is one of the mostly highlighted complaints made by the individuals in current social context. Though the technology has been very supportive in building and maintaining relationships among individuals, it is still very seldom used to enhance the ability of recognizing emotions: emotional intelligence. As the initial step in developing a model that non-intrusively recognizes...
The separation of the fundamental from a distorted waveform is an important component in the implementation of a custom power device. A novel scheme for a vector-locked loop (VLL) for synchronous extraction of harmonics/fundamental in a distorted periodic waveform is described here. An intuitive, though approximate, explanation is provided for the operation of the algorithm, focusing on the locking...
3-Dimensional Television (3D-TV) is an emerging area of consumer entertainment, which gives its viewers an added dimension of experience. At the moment 3DTV is going through a series of standardization activities, especially to finalize a representation technique. Extra information that needs to be transmitted in 3D-TV systems has brought about new problems that need to be solved. Models have been...
Cloud computing is the long dreamed vision of computing as a utility, where data owners can remotely store their data in the cloud to enjoy on-demand high-quality applications and services from a shared pool of configurable computing resources. While data outsourcing relieves the owners of the burden of local data storage and maintenance, it also eliminates their physical control of storage dependability...
This research project mainly focus on proper coordination of chiller and supporting components in order to reduce it's operating cost, improve temperature stability and improve equipment life. Control algorithm measures critical parameters and adjust variable outputs to optimize number of running compressors, chill water pumps and air handler units with improved performance. Case study was done at...
Digitizing printed document is always a challenge faced by the computing society. Digitization of text not only allows users to easily modify and reprint printed documents, but also is a need of the day due to the use of word-search capability available at disposal in this era. Converting a printed document into a stream of characters using OCR (optical character recognition) techniques is a widely...
Control the data flow between device interfaces, processing blocks and memories in a vision system is complex in hardware implementation. In the research, high-level synthesis tool is used to design, implement and test the vision system within the context of required control, synchronization, and parameterization on a processor based platform. In addition, both HLS tools and HDL were used for the...
