Geospatial information is used as a core base information for U-City in all areas including planning, construction, operation, and management, and it is a service factor inevitable for U-City residents' convenience and safety. Spatial information required for U-City are digital map, ortho image, various facilities drawing, estate site plan, and so on. In addition, airborne/terrestrial LiDAR, RFID,...
The problem of outlier detection is well studied in the fields of Machine Learning (ML) and Knowledge Discovery in Databases (KDD). Both fields have their own methods and evaluation procedures. In ML, Support Vector Machines and Parzen Windows are well-known methods that can be used for outlier detection. In KDD, the heuristic local-density estimation methods LOF and LOCI are generally considered...
Numerous algorithms exist for producing gene sets from high-throughput genomic and proteomic technologies. However, analysis of the functional significance of these groups of genes or proteins remains a big challenge. We developed a Web based system called gene-set cohesion analysis tool (GCAT) for estimating the significance level of the functional cohesion of a given gene set. The method utilizes...
For ubiquitous computing environments, an important assumption is that all the components in any specific environment are connected with each other. With this assumption, we can share various kinds of content across mobile terminals. This paper introduces an effective scheme to manage multimedia sharing based on specially designed profiles and a virtual community. A virtual community is defined as...
In the ubiquitous computing environment, image processing system will play an increasingly more significant role in ensuring safety of industrial sites in the future. In step with the advancements of image processing technologies, surveillance monitoring system and automation system are under the spotlight as key elements in industrial sites and leveraging intelligent ubiquitous systems effectively...
In this paper, VCC registration and polymer-multiwalled carbon nanotube (MWCNT) composite emitter material thermal destruction during emitting process were investigated. This paper was focused on the so called emission point temperature which was related to thermal degradation for neighboring polymer molecules around CNT. Time of flight mass spectroscopy (TOF-MS) and field emission process were involved...
A nitric oxide (NO) electrochemical sensor for hypoxic, tumor cell culture applications is developed. Qualitative analysis of the electrode has been studied by cyclic voltammetry. NO amperometric measurement methods have been extensively analyzed. Square wave voltammetry method is found to be one of the optimal methods for the measurement of NO in cell cultures. A hypoxic tumor cell culture measurement...
Today the most successful biometric based identification technologies such as fingerprint, iris, retina, palm and face recognition are used worldwide in both criminal investigations and high security facilities. These technologies are well-studied, but research shows they have many drawbacks which decrease the success of the methods applied. Ear images are not affected by emotional expression, illumination,...
Organizations attempting to embark on the knowledge management (KM) journey need information, inputs, examples and role models from existing adopters or practitioners to help them adopt it. Hence, it is strongly believed that the growing research and literature in the KM domain should be more focused on its practical perspective. This paper represents a practical oriented work that reports on how...
Synchrophasors are no longer an academic curiosity. Today synchrophasors are providing solutions that otherwise would have been too expensive or too complicated to implement with traditional approaches. This paper examines ten synchrophasor applications being applied to monitor, visualize, and control electric power systems. 1. Voltage and current phasing verification 2. Substation voltage measurement...
In this work, an IR-UWB RF Receiver compliant with 802.15.3a standard is fabricated on a single chip using 0.18um CMOS technology. The Receiver chip covers 3-5GHz lower band and 3-stage LNA is realized without on-chip inductor, which reduces the chip size dramatically down to 1.8mmx 0.9mm. The input signal is differential type in order to improve the immunity from common mode noise and undesired harmonic...
A microstrip filter based on a single-ring Bandpass section integrated with a band-trimming section incorporating two cascaded rings was demonstrated featuring enhanced suppression. The stop-band for the input bandpass section could be selectively eliminated via the proposed band-tailoring section without causing any excessive loss, thereby improving the overall transmission of the device with regard...
