Blood urea nitrogen (BUN) is an indicator of dehydration in patients at risk of developing acute stroke-in-evolution, and BUN level detection in such patients can help prevent such a diagnosis. This study developed the key module components of and techniques employed by a BUN analyzer that is suitable for use during home care. Based on suggestions by health professionals, an analyzer was developed,...
We devise a novel phase and time error measurement technique for 10 MHz and 1 PPS reference signals, based on Software Defined Radios (SDR) and Digital Signal Processing (DSP). The proposed measurement setup allows us to employ two synchronized type N210 Universal Software Radio Peripheral (USRP) devices with LFRX daughterboards to realize an economically priced and easy-to-use quad-channel measurement...
There are already plenty of Internet of Things (IoT) architectures and systems available worldwide and this creates challenges for software development and systems entities that use these platforms. Global visibility and interoperability through the exposure of these platforms via the web can be achieved through a new paradigm to support an open framework for Web of Things (WoT), which is analogous...
Network devices rely on forwarding rules to forward packets. With the latest OpenFlow standard (the de-facto software defined network standard), the rules that make up a forwarding set may be expressed in the form of a single table or multiple linked tables. This raises the question of how to reconcile the forwarding behaviour of different flow tables? In this paper we propose two approaches to convert...
The Bluetooth Low Energy technology has become more and more popular among wearable devices due to its low price and reduced power consumption. However, the development industry has oriented itself among mobile platforms neglecting the standard operating systems and providing only a limited set of integration possibilities most often using a smart-phone, restricting in this way the utility of such...
E-learning System has become a common constituent unit of web page of any higher education institution. At the Polytechnic Nikola Tesla in Gospic Loomen is established since 2010, a system that is designed in a role of teaching repository for students and for preparation of e-courses for the teachers and students. The aim of this paper is by using descriptive and inferential statistics, and based...
Service virtualization is an approach that uses virtualizedenvironments to automatically test enterprise services inproduction-like conditions. Many techniques have been proposedto provide such a realistic environment for enterprise services. The Internet-of-Things (IoT) is an emerging field which connectsa diverse set of devices over different transport layers, usinga variety of protocols. Provisioning...
The application of Information Retrieval (IR) techniquesto software traceability link recovery has been the focusof many studies. These studies have formulated the task ofestablishing valid trace links between two types of softwareartifacts as a retrieval problem, where one type of artifacts isselected as the set of queries and the other as the corpus. Previouswork selected the sets of queries and...
Exception handling allows developers to deal with abnormal situations that disrupt the execution flow of a program. There are mainly three types of exceptions: standard exceptions provided by the programming language itself, custom exceptions defined by the project developers, and third-party exceptions defined in external libraries. We conjecture that there are multiple factors that affect the use...
The new Ultra High Definition (UHD) standard digital imagery can represent much more color information than High Definition (HD) and Standard Definition (SD). Currently most manufactured displays support UHD colors while UHD is being deployed for content production. However not all service providers have updated their pipeline thoroughly. Thus, the enduser that buys a UHD display would not be able...
Open-source projects rely on attracting new and retaining old contributors for achieving sustainable success. One may suspect that adopting new development practices like Continuous Integration (CI) should improve the attractiveness of a project. However, little is known about the impact that adoption of CI has on developer attraction and retention. To bridge this gap, we study how the introduction...
Software developer turnover has become a big challenge for information technology (IT) companies. The departure of key software developers might cause big loss to an IT company since they also depart with important business knowledge and critical technical skills. Understanding developer turnover is very important for IT companies to retain talented developers and reduce the loss due to developers'...
The User Requirements Notation is a standard published by the International Telecommunication Union that contains two complementary notations for goal and scenario/workflow modeling. Use Case Maps (UCM) – the workflow notation – focuses on the causal relationships of the steps in a workflow without requiring the specification of detailed message exchanges and data. A UCM model captures the interactions...
Hyphenated techniques involving ICP-MS are popular in research and application areas. Micro reactors which are widely integrated to molecular mass spectrometric techniques, however, find little application in the field of atomic spectroscopy in general or ICP-MS in specific. In this work, two integration concepts have been proposed for the integration of a micro reactor system to the Agilent 7700x...
Recent research has provided evidence that software developers experience a wide range of emotions. We argue that among those emotions anger deserves special attention as it can serve as an onset for tools supporting collaborative softwaredevelopment. This, however, requires a fine-grained model of the anger emotion, able to distinguish between anger directed towards self, others, and objects. Detecting...
With the strong growth of power devices into 2020 and beyond (5.3% CAGR from 2016–2021 [1]), average Si Epitaxial (epi) thickness has been increasing to support 400–1000V devices, the largest market segment in power. The current epi chamber offerings are primarily used for thin epi (<20;1m), in some cases for thicknesses up to 60pm, where batch reactors are mostly used because of throughput, cost,...
Certification schemes exist to regulate software systems and prevent them from being deployed before they are judged fit to use. However, practitioners are often unsatisfied with the efficiency of certification standards and processes. In this study, we analyzed two certification standards, Common Criteria and DO-178C, and collected insights from literature and from interviews with subject-matter...
Process development and maintenance are fundamental jobs in process-centered engineering, e.g., software process improvement. A IoT of methods have been proposed for process modeling, and many of them have dedicated to improve process reuse by means of pattern or template techniques. In this paper, we propose an approach implementing the definition of Process Template Models and Template Customization...
Automatic text summarization has been widely studied for more than fifty years. In software engineering, automatic summarization is an emerging area that shows great potential and poses new and exciting research challenges. This technical briefing provides an introduction to the state of the art and maps future research directions in automatic software summarization.
Due to the increasing complexity of software systems, model-driven engineering has been introduced to shift the developer's focus from machine-centric program code to human-centric models of the software under development. In model-driven approaches, program code in conventional programming languages (e.g., C++, Java) is commonly generated from models and then compiled or interpreted. Intermediate...
