The problems associated with multipath routing in Border Gateway Protocol (BGP) for Autonomous Systems (ASes) can be solved with some model or control systems from the Software Defined Networking (SDN). The SdN controller could be used to solve the inconsistencies in the scalability and latency of the Routing Information Base (RIB) of ASes. Also, a set of modules for Inter-AS routing and Brokering...
With Network Function Virtualization (NFV) generating significant interest in the network operator community, many network functions, including the LTE EPC, are being built as virtualized software appliances running on commodity hardware, as opposed to custom hardware. To provide fault tolerance and scalable performance, the virtualized network functions are typically built in a clustered architecture,...
The Extensible Messaging and Presence Protocol (XMPP) is one of the most popular Instant Messaging (IM) protocols which uses a client-server working mode. This protocol uses different connection primitives for both client-to-server (c2s) and server-to-server (s2s) connections. It is actively used in mission-critical operations where the reliability and security of communication systems is always imperative...
What would have happened if I did not have any code smell? This is an interesting question that no previous study, to the best of our knowledge, has tried to answer. In this paper, we present a method for implementing a what-if scenario analysis estimating the number of defective files in the absence of smells. Our industrial case study shows that 20% of the total defective files were likely avoidable...
A simulation method of non-uniform interface charges in pMOSFETs was presented in this paper. By using the 2D device simulation software, it increases the non-uniform interface charges array and calculation module. Bonded with the device negative bias temperature instability NBTI (Negative Bias Temperature Instability) degeneration model, the pure bias NBTI (Pure Drain Bias NBTI) degradation impact...
Inorganic phosphor material, gadolinium oxysulphide active with terbium (Gd2O2S:Tb3+) has been previously investigated as a scintillator used in the dosimeter to detect the X-Ray dose due to its high light yield efficiency of converting the X-Ray into the visible green lights. Apart from the properties of light yield efficiency, fast scintillation and lower energy resolution matters for the clinic...
This paper examines the impact of departmental policy changes on the trend in DFW proportions for Calculus II at a large research university. Calculus I and II have been shown to be barrier courses for STEM majors, so increasing student success in these courses is imperative to retaining more students in STEM fields. A study was conducted to investigate how the DFW proportions for Calculus II changed...
In Software Defined Networking (SDN), connections between the controller and the switches are maintained in two ways: out-of-band and in-band. In out-of-band controlling, the control channels are constructed via separate links. However, due to several reasons, sometimes in-band controlling is needed instead of out-of-band controlling. In in-band controlling, the data paths are used for control channels...
The main goal of the US Science Gateways Community Institute (SGCI) is to serve science gateways to achieve sustainability and growth. Science gateways allow science and engineering communities to access shared data, software, computing services, instruments, educational materials, and other resources specific to their disciplines. Thus, science gateways are a subgroup of scientific software and the...
Nowadays multiple bus communication types are comprehensively employed to construct different networks in vehicles information system design. Data interchange among these networks must be conducted through complex communication gateways, which are difficult to test all the features wholly by manual work. MIC and RS422 communication networks are very common in some special vehicles, so in this paper...
The Servai Mesh and new Serval Mesh Extender 2.0 low-cost, weather-proof, open-source, infrastructure-communications device is being piloted in Vanuatu during 2017 with the support of the Australian Department of Foreign Affairs and Trades Pacific Humanitarian Challenge. This pilot will test the applicability and utility of the Serval Mesh software and hardware in one of the world's most disaster-prone...
Modern vehicles employ a large amount of distributed computation and require the underlying communication scheme to provide high bandwidth and low latency. Existing communication protocols like Controller Area Network (CAN) and FlexRay do not provide the required bandwidth, paving the way for adoption of Ethernet as the next generation network backbone for in-vehicle systems. Ethernet would co-exist...
In recent years, synthetic test instruments have become increasingly popular in the automatic test equipment (ATE) market. This type of instrument gives users the ability to create custom solutions to better meet their test requirements. FPGA (Field Programmable Gate Array) based solutions are the most common synthetic test instrument on the market today. FPGA based solutions can work well due to...
Although Internet of Things (IoT) is an evolving paradigm which allows everyday physical objects, devices and appliances to connect to the internet, and to communicate with each other, there are several essential challenges that should be addressed. One of them is big data generated by physical objects. It is quite challenging to manage and control such enormous amount of data. In this paper, we propose...
This paper presents a technique to integrate wireless field devices using WirelessHART and ISA100.11a technologies into a condition monitoring system based on Wonderware InTouch software. The proposed integration brings the data from a field site with digital multi-device networking for automatic data collection to support the condition monitoring of instruments or smart connected equipment in preparation...
Business processes may accept variants based on specific business requirements of an organization, leading to the definition of a process family. There are many proposals for the modeling of the common and variable parts of a process family, as well as to support the customization of each process variant (i.e., process configuration or tailoring). In this article, we present the results of a detailed...
Due to C's overwhelming dominance in industry, reactive embedded applications usually rely on conventional sequential programming. Adopted approaches favor event-driven paradigms which prevent function-oriented code decomposition in particular. This encourages the violation of fundamental software engineering principles. The reactive programming paradigm is proposed as a general solution. However,...
Traditional experiments and EDA technique-based CPLD experiments have their own characteristics in digital logic experiment teaching. Therefore, we try to combine such two kinds of experiments in teaching with the aim of taking full advantage of them. This paper introduces the practice in digital logic experiment teaching based on experimental platform, which is under the guidance of such ideas. We...
The Internet of Things (IoT) continues to expand in terms of the number of connected devices. To handle the data produced by those devices, gateways are deployed to collect data, possibly to analyze it, and finally to send it to the cloud or to the end-user to support new services. This process involves complex software that is deployed on those gateways. Moreover, the dynamicity due to new services,...
This paper presents an exploratory study aimed at identifying the pain points that novice programmers experience, from the software engineering perspective, when developing and deploying smart and distributed systems, that may be classified as Ambient Intelligence (AmI) systems. The exploratory study was conducted among undergraduate students, that worked in groups for developing AmI projects during...
