Complex situations and systems can be studied by using adequate models in simulation. An important aspect of models and the simulation software is the ability to use a wide range of possible input parameters. The simulation described in this paper is based on agile manufacturing by using transport robots and cheap reconfigurable production platforms, called equiplets. This setup makes agile manufacturing...
The video wall technology has many usefulapplications. However, the high cost of the video wall might makeit unavailable when needed. The PiWall is a low-cost alternativefor a traditional video wall. The PiWall project was built to meetvery specific requirements, therefore it has very limitedapplications. The most recognizable problem on the currentsystem is that it needs to restart every time a change...
Service computing has become very popular nowadays in providing big data analytics. The proposed system deals with how to implement software as a service product for a healthcare domain. Healthcare data has its sources mainly from Electronic health records (EHR), Mobile health applications, wireless medical devices and also wearable devices that can track patient activity. This huge volume of data...
Emerging healthcare systems are expected to leverage new Internet of Things (IoT) trends to enable preventive and personalized medicine. However, the success of such systems is entirely dependent on the ability to preserve patient privacy. This paper proposes a decentralized ontology based system architecture that caters to a healthcare organization's privacy needs as well as its enterprise security...
There is an increasing demand to reduce cost and shorten the development period. Though an automation system consists of sub-systems, each sub-system is large. Therefore, the development of such a system is complex. In addition, an automation system, in which there are a wide variety of object requests, may not achieve the processing performance of the target depending on the combination and arrangement...
ith the wide deployment of various kinds of sensors in fixed infrastructures and in mobile devices, technologies and applications of crowd-sensing has drawn attentions in the fields of mobile computing. This paper studies the design of frameworks for crowd-sensing process in a distributed environment. We discuss the realization of the compatibilities of devices and services, as well as the algorithms...
Time synchronization is critical for parallel and distributed simulation (PADS). In this paper we first compare the two main synchronization mechanisms in PADS, namely conservative and optimistic protocols. Then we propose a Minimum Time Buckets synchronization algorithm, which can optimistically schedule events without sending anti-messages. Comparing to the well-known Breathing Time Bucket (MTB)...
Parallel simulation technology is broadly used in complex system and real time simulations, such as Autonomous Decentralized System (ADS) and Internet of Things (IoT). Rollback mechanism is a key factor to improve the performance of optimistic parallel simulation. In this paper we first introduce the common time synchronization protocols and rollback recovery mechanisms in parallel simulation. Then...
Services Oriented Architectures (SOA) represents a newmodel in the traditional way of designing systems becauseit is constructed around individual processes of different areas in an organization. In recent years, the necessity to integrate critical applications in a SOA has increased, that is the case of the Financial Applications. These applications require high reliability, information consistency...
Automatic defects inspection and classification inceramic tile plays a crucial role in ceramic tiles industry. Inorder to improve the required computing time to detect andclassify spot and crack defects in ceramic tiles, this paperproposed parallel algorithms based on the graphical processingunit. The proposed algorithm divides ceramic tile images intonon-overlapped partitions, identifies the defected...
This paper reports the newly designed programming course developed and taught at Zhejiang University for a freshman class majoring in information science and electronic engineering, and disseminated to many other universities, to address the enrollment crisis as reported by ACM Curriculum Committee Review Task Force. The course teaches the basic information science and electronic engineering concepts...
Recently, much attention has been paid to unmanned aircraft systems (UAS), especially for civilian purposes such as disaster prevention and transportation. This paper considers big long-flight-type UASs remotely piloted from ground station by radio communication link, since these types of UASs require higher reliability. The purpose of this paper is to consider a communication system which transmits...
This paper presents an improved pedestrian tracking algorithm with image sequences acquired by surveillance cameras. This pedestrian tracking algorithm is based on mean shift algorithm, and it uses color histogram equalization to improve the original algorithm. The improved algorithm performs much better than the original algorithm in some situations. We use the CAVIAR project/IST 2001 37540 dataset...
Blockchain is a technology of recording ledgers in a distributed manner. It uses a consensus mechanism, digital signature and hash chains to realize the reliable storage of ledgers, and provide services such as traceability, integrity and no-repudiation for transactions in ledgers in a decentralized way. These services make blockchain have great application potentiality in the fields of healthcare,...
In order to achieve safe, secure, efficient and environmentally sustainable air traffic management at global, regional and local levels, the system-wide operational information exchange and life-cycle management technologies are required. The System Wide Information Management (SWIM) is to provide a collaborative air traffic management environment for system-wide interoperability and harmonization...
Due to the rapid economic growth around the world, air traffic also has increased rapidlly. Today's Air Traffic Management (ATM) system is comprised of a wide variety of application developed for specific purposes, such systems use various custom communication protocols and each system has its own self-contained information system. For this reason, ICAO has proposed the concept of SWIM for effective...
For aviation safety human related mistakes cannotbe neglected. Control tower operators can become a potentialrisk for aviation safety. These operators check the status ofaircraft by visualization and their communication with the pilotstarts when the aircraft is near the runway. Due to theenvironment in which these operators work these operators canhave problems hearing the pilot. To minimize the risk...
