In this paper, we try to formally analyze risk dependencies on a global logistics process that is made up of a set of RFID-driven biz-steps2. In enacting a global logistics process, it is very important to control and trace each bizstep's execution as well as to visualize its status. Moreover, for the sake of improving QoS (the quality of services), it ought to be crucial for the system to provide...
Breath tests are attractive since they are noninvasive and can be repeated frequently changing state of critically ill patients. Analysis of exhaled breath for recognition of human diseases using endogenous volatile organic compounds offers the possibility of noninvasive diagnosis. We investigated screening method of lung cancer. The system for screening of lung cancer was made by using metal oxide...
Smart phones such as the iPhone and Android phones have become increasingly popular in the recent market. Diverse applications can be implemented on smart phones since their performance has been improved. One of the promising application areas would be reading the emotional state of a human being and using it for communicating with the computer. In this paper, we present a robust facial expression...
ZnO nanowires were synthesized via a vapor transport synthesis route. These nanowires were characterized by X-ray diffraction (XRD), field scanning electron microscopy (FESEM) and UV -- vis spectroscopy. The results of XRD revealed that monophasic nature of ZnO. The observation of FESEM images showed that the obtained ZnO nanowires were homogenous with average diameter of 30 nm. The photocatalytic...
Contexts are appreciated as localized background knowledge for operations in knowledge management and applications. However, current context representations ignore the characters that contexts have different size, have multi-layer contextual dimensions, and contain both metadata and instances. In order to improve context representation, this paper proposes a novel context representation approach based...
The schedule management of construction work is an important method to complete a construction project within a given period of time. There are attempts to carry out construction project management by IT and web basis. Thus we need to mediate the progress schedule and update to carry out well-planned progress management in a web page. This research proposes a method to manage construction schedules...
This paper presents an analysis of thirty-two (32) ICT integration initiatives of different extent and reach coming from the private sector, academe, and the government over the past ten years. This study uses the ICT for Education (ICT4E) vision of the Philippine Department of Education as the framework in analyzing these initiatives. This study seeks to: 1) identify particular components of ICT...
Our society suffers from losses because of various and complicated disasters, so government organizations are struggling to mitigate disasters to prevent a growing number of casualties. Research on disaster risk warnings has been growing steadily, and at present there are a number of places equipped with the warning systems. However, this service is not applicable for small-scale disasters because...
In this paper we analyze the validity of their model. For a kickoff, we prove the reliability of obtained questionnaire data by using the internal consistency method and split-half reliability method. And then, we will evaluate the validity of this model by the nomological validity method and the causality analysis for verifying the practicality and the effectiveness of the e-marketing process model.
In this paper, a discriminative training technique based on Gaussian Mixture Model (GMM) is proposed for detection and classification of abnormal acoustic events in indoor environment. In particular, we consider small indoor space such as vehicular scenes and develop a two-step procedure in which statistical mapping of acoustic features is followed by abnormal event detection. In the first step, Mel-...
Advancements in sensor technology have enabled the development of extremely small, low-power, low-cost sensing devices. Recently, wireless sensor networks (WSNs) with thousands of those tiny sensors have become increasingly common. The existing and potential WSN applications span a wide spectrum across various domains. In terms of data reporting schemes, WSNs can be categorized as time-driven and...
One of the method to improve performance of QoS is retransmission. For retransmission, one-way delay is essential because it should be known for correct retransmission. This paper proposes a one-way delay estimation scheme for efficient retransmission. In the proposed scheme, one-way delay is estimated by packet intervals. The simulation results demonstrate that estimated one-way delay is similar...
ICT systems have been investigated for flexible systems configuration, systems operation cost reduction, environmental impact reduction, etc. Cloud computing has attracted attention as technology that solves these. In the U.S., business Cloud services, such as Amazon EC2/S3, Google Apps, Force.com, and Windows Azure, are gaining more and more users. Additionally, study of Cloud computing, such as...
Specification-based testing of concurrent software systems always faces strong challenges. One main reason is that there exists nondeterminism in both the specifications and the corresponding programs. For this reason, it is not easy to generate test cases on the basis of a specification, the execution of a test case may not follow a specification trace (or scenario) as expected, and the testing result...
This paper proposes a location-aware asynchronous message delivery (AMD) for in-door wireless sensor network environment consists of mobile and stationary nodes. In order to realize the proposed concept, we design the Location-ID eXchange (LIDx) protocol as a location-tracking technique using the static location information of stationary nodes, and the AMD middleware to maintain the location of all...
This paper proposes an efficient message authentication scheme providing non-repudiation of the smart metering service in Smart Grid. One of the main challenges in securing Advanced Meter Infrastructure is to accomplish message authentication and non-repudiation services in the metering service. Low power consumption of cryptographic operations in smart meter devices is another critical issue. The...
In this paper, we propose a digital implementation of the antenna interface standards group (AISG) modem for the remote control and monitoring of antenna line devices (ALDs) through an antenna feeder cable. The proposed modem is implemented in Altera EP3C16E144C8 device, together with an 8-bit ADC and a BPF. It operates at variable data rates of 9.6, 38.4, and 115.2 kbps based on the OOK modulation...
Nowadays, in Publish/Subscribe system, the number of subscriptions from customers can be large, the events happening in such a system are more frequent and the notification load is heavy. Combining with cloud computing that is becoming increasingly popular for scalability and availability it promises, called Sensor-Cloud, there are many approaches that improve data delivery issues in such scenario...
