Smart Tools in Software Engineering: A Systematic Mapping Study
Venue: 2019 42nd International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO)
Year: 2019

Software development processes such as waterfall development model have been around for over fifty years, but still, even modern software development approaches, such as DevOps or Test driven development, fundamentally rely on the same principles and phases as everything before them. Yet, the modern world imposes new challenges for software businesses, and new ways of digital distribution require new ways of resource provisioning and ability to reduce the time to market to its absolute minimum. In this study, we identify and analyze the technologies which may be useful for software companies to ease the development and maintenance work by assisting the experts to collect relevant information and observe issues before they cause process disturbances. As a result, we describe a mapping study, which identifies different approaches to developing a smart software engineering tools applying potential technologies such as artificial intelligence, cloud based service models, adaptive measurement, and other approaches, which could offer significant benefits to the software development process.

Promoting healthy food preferences from the start: a narrative review of food preference learning from the prenatal period through early childhood
Venue: Obesity reviews an official journal of the International Association for the Study of Obesity
Year: 2018

The palatable, energy dense foods that characterize modern environments can promote unhealthy eating habits, along with humans' predispositions to accept sweet tastes and reject those that are sour or bitter. Yet food preferences are malleable, and examining food preference learning during early life can highlight ways to promote acceptance of healthier foods. This narrative review describes research from the past 10 years focused on food preference learning from the prenatal period through early childhood (ages 2 5 years)
An energy efficient architecture for internet of things systems
Venue: SPIE Defense Security
Year: 2016

In this paper some of the motivations for energy efficient communications in wireless systems are described by highlighting emerging trends and identifying some challenges that need to be addressed to enable novel, scalable and energy efficient communications. So an architecture for Internet of Things systems is presented, the purpose of which is to minimize energy consumption by communication devices, protocols, networks, end user systems and data centers. Some electrical devices have been designed with multiple communication interfaces, such as RF or WiFi, using open source technology; they have been analyzed under different working conditions. Some devices are programmed to communicate directly with a web server, others to communicate only with a special device that acts as a bridge between some devices and the web server. Communication parameters and device status have been changed dynamically according to different scenarios in order to have the most benefits in terms of energy cost and battery lifetime. So the way devices communicate with the web server or between each other and the way they try to obtain the information they need to be always up to date change dynamically in order to guarantee always the lowest energy consumption, a long lasting battery lifetime, the fastest responses and feedbacks and the best quality of service and communication for end users and inner devices of the system.
Targeted metabolomics of CSF in healthy individuals and patients with secondary progressive multiple sclerosis using high resolution mass spectrometry
Venue: Metabolomics
Year: 2020

Standardized commercial kits enable targeted metabolomics analysis and may thus provide an attractive complement to the more explorative approaches. The kits are typically developed for triple quadrupole mass spectrometers using serum and plasma.  Here we measure the concentrations of preselected metabolites in cerebrospinal fluid (CSF) using a kit developed for high resolution mass spectrometry (HRMS) Secondarily, the study aimed to investigate metabolite alterations in patients with secondary progressive multiple sclerosis (SPMS) compared to controls.  We performed targeted metabolomics in human CSF on twelve SPMS patients and twelve age and sex matched healthy controls using the Absolute IDQ p400 kit (Biocrates Life Sciences AG) developed for HRMS. The extracts were analysed using two methods; liquid chromatography mass spectrometry (LC HRMS) and flow injection analysis MS (FIA HRMS) Results Out of 408 targeted metabolites, 196 (48% were detected above limit of detection and 35 were absolutely quantified. Metabolites analyzed using LC HRMS had a median coefficient of variation (CV) of 3% and 2.5% between reinjections the same day and after prolonged storage, respectively. The corresponding results for the FIA HRMS were a median CV of 27% and 21% respectively. We found significantly (p 0.05) elevated levels of glycine, asymmetric dimethylarginine (ADMA) glycerophospholipid PC O (34:0) and sum of hexoses in SPMS patients compared to controls.  The Absolute IDQ p400 kit could successfully be used for quantifying targeted metabolites in the CSF. Metabolites quantified using LC HRMS showed superior reproducibility compared to FIA HRMS.
Fast Scalable Approximate Nearest Neighbor Search for High dimensional Data
Venue: 2020 IEEE International Conference on Cluster Computing (CLUSTER)
Year: 2020

K Nearest Neighbor (k NN) search is one of the most commonly used approaches for similarity search. It finds extensive applications in machine learning and data mining. This era of big data warrants efficiently scaling k NN search algorithms for billion scale datasets with high dimensionality. In this paper, we propose a solution towards this end where we use vantage point trees for partitioning the dataset across multiple processes and exploit an existing graph based sequential approximate k NN search algorithm called HNSW (Hierarchical Navigable Small World) for searching locally within a process. Our hybrid MPI OpenMP solution employs techniques including exploiting MPI one sided communication for reducing communication times and partition replication for better load balancing across processes. We demonstrate computation of k NN for 10,000 queries in the order of seconds using our approach on ~8000 cores on a dataset with billion points in an 128 dimensional space. We also show 10X speedup over a completely k d tree based solution for the same dataset, thus demonstrating better suitability of our solution for high dimensional datasets. Our solution shows almost linear strong scaling,
Metallic nanostructures for light trapping in energy harvesting devices
Year: 2014

Solar energy is abundant and environmentally friendly. Light trapping in solar energy harvesting devices or structures is of critical importance. This article reviews light trapping with metallic nanostructures for thin film solar cells and selective solar absorbers. The metallic nanostructures can either be used in reducing material thickness and device cost or in improving light absorbance and thereby improving conversion efficiency. The metallic nanostructures can contribute to light trapping by scattering and increasing the path length of light, by generating strong electromagnetic field in the active layer, or by multiple reflections/absorptions. We have also discussed the adverse effect of metallic nanostructures and how to solve these problems and take full advantage of the light trapping effect. In recent years, researchers have demonstrated a number of new schemes for enhancing the absorption of light in solar cells. Chuan Fei Guo and colleagues from the University of Houston in the USA and National Center for Nanoscience and Technology of China in Beijing have now reviewed the use of metallic nanostructures for trapping light in photovoltaic devices. In particular, the presence of metallic nanoparticles in a solar cell or a solar absorber can aid light absorption by inducing strong, local field enhancement effects or coupling to resonant plasmon modes. Such particles can also promote scattering and thus increase path lengths for light within the device. Solar cells that utilize this approach are either more efficient or substantially thinner than those that do not, thus reducing material costs and creating the opportunity for ultrathin, flexible devices.
Characteristics of personal health records: findings of the Medical Library Association/National Library of Medicine Joint Electronic Personal Health Record Task Force.
Venue: Journal of the Medical Library Association JMLA
Year: 2010

The Medical Library Association (MLA)/National Library of Medicine (NLM) Joint Electronic Personal Health Record Task Force examined the current state of personal health records (PHRs)  A working definition of PHRs was formulated, and a database was built with fields for specified PHR characteristics. PHRs were identified and listed. Each task force member was assigned a portion of the list for data gathering. Findings were recorded in the database.  Of the 117 PHRs identified, 91 were viable. Almost half were standalone products. A number used national standards for nomenclature and/or record structure. Less than half were mobile device enabled. Some were publicly available, and others were offered only to enrollees of particular health plans or employees at particular institutions. A few were targeted to special health conditions.  The PHR field is very dynamic. While most PHR products have some common elements, their features can vary. PHRs can link their users with librarians and information resources. MLA and NLM have taken an active role in making this connection and in encouraging librarians to assume this assistance role with PHRs.
Chinese Outbound Tourism as an Instrument of Economic Statecraft
Year: 2020

China's growing economic strength provides Beijing with potent instruments of economic statecraft to pursue political and strategic objectives. Yet studies of economic power and Chinese economic statecraft tend to concentrate on trade in goods, outbound investment, and international institutions. This article broadens this research program into trade in services by focusing on China's outbound tourism sector. Drawing on a variety of Chinese and English language sources, the authors describe the history and structure of the domestic regulatory framework governing Chinese outbound tourism, before studying instances where the government has apparently intervened for strategic purposes. By unpacking how Chinese consumers arrange overseas holidays, this article provides insights into how the market structure of this service industry creates both opportunities for and constraints on China's economic power.
Feature based building orientation optimization for additive manufacturing
Year: 2016

The purpose of this paper is to present research work based on the authors' conceptual framework reported in the VRAP Conference 2013. It is related with an efficient method to obtain an optimal part build orientation for additive manufacturing (AM) by using AM features with associated AM production knowledge and multi attribute decision making (MADM) The paper also emphasizes the importance of AM feature and the implied AM knowledge in AM process planning.  To solve the orientation problem in AM, two sub tasks, the generation of a set of alternative orientations and the identification of an optimal one within the generated list, should be accomplished. In this paper, AM feature is defined and associated with AM production knowledge to be used for generating a set of alternative orientations. Key attributes for the decision making of the orientation problem are then identified and used to represent those generated orientations. Finally, an integrated MADM model is adopted to find out the optimal orientation among the generated alternative orientations.  The proposed method to find out an optimal part build orientation for those parts with simple or medium complex geometric shapes is reasonable and efficient. It also has the potential to deal with more complex parts with cellular or porous structures in a short time by using high performance computers.  The proposed method is a proof of concept. There is a need to investigate AM feature types and the association with related AM production knowledge further so as to suite the context of orientating parts with more complex geometric features. There are also research opportunities for developing more advanced algorithms to recognize AM features and generate alternative orientations and refine alternative orientations.  AM feature is defined and introduced to the orientation problem in AM for generating the alternative orientations. It is also used as one of the key attributes for decision making so as to help express production requirements on specific geometric features of a desired part.
Bureaucracy, The Holocaust and Techniques of Power at Work
Year: 2009

The generational properties of organization theory are an increasing topic for analysis, usually in terms of what is addressed and how it is addressed. Some writers have alerted us to the importance of those social issues that are not addressed. Combining the idea of generational scholarship with the idea of those non issues that remain unaddressed, this paper highlights how some of the events of the Second World War, which authorities agree was a generational defining and demarcating experience, have been neglected in organization theory. Nowhere is this more clearly demonstrated than in the Holocaust. Strangely, this practical experiment in organizational design and practice seems to have elided almost all interest by organization theorists, whether functionalist or critical. The paper addresses this elision and draws on the work of Goffman, Foucault and Bauman to address the very material conditions of organizational power and raise some ethical issues about the commitments of organization scholars.
Nature and extent of outpatient podiatry service utilisation in people with diabetes undergoing minor foot amputations: a retrospective clinical audit
Venue: Journal of Foot and Ankle Research
Year: 2021

People with diabetes are at high risk of foot complications that can lead to lower extremity amputations. National standards suggest that early assessment and management by a podiatry led multidisciplinary high risk foot clinic (HRFC) helps to reduce complications. This review is a retrospective audit of the Central Coast Local Health District (CCLHD) podiatry department service utilisation in people with diabetes who had undergone a minor foot amputation.  All people with diabetes who had minor foot amputations in the calendar year 2017 in the CCLHD in New South Wales were identified. Podiatry occasions of service from all podiatry service clinics (e.g. general, orthoses, wound, HRFC) and hospital stays for 12 months prior to, and 12 months, post the minor foot amputation were extracted.  Data on 74 people with diabetes who underwent 85 minor foot amputations were collected. In the 12 month period leading up to their minor foot amputation less than half, 42% n =31) of the patients had attended any of the available podiatry service clinics within the CCLHD system. Post amputation and discharge from hospital there was an overall rise of 26% in numbers attending all CCLHD podiatry led clinics bringing the total to 68% (51) However, attendance at the HRFC rose by only 2% from 16% n =12) to 18% n= (13)  This study shows that there was underutilisation of Podiatry Services in the CCLHD in 2017 with some participants not meeting national treatment guidelines for foot health services. Revision of current referral pathways both prior to, during and following hospitalisation and expanding the multidisciplinary HRFC to accommodate the population by providing more accessible locations has since been undertaken to increase service access. Further provision of education to those highlighted to be at high risk has also been implemented.
Channel and Perennial Flow Initiation in Headwater Streams: Management Implications of Variability in Source Area Size
Venue: Environmental management
Year: 2007

Despite increasing attention to management of headwater streams as sources of water, sediment, and wood to downstream rivers, the extent of headwater channels and perennial flow remain poorly known and inaccurately depicted on topographic maps and in digital hydrographic data. This study reports field mapping of channel head and perennial flow initiation locations in forested landscapes underlain by sandstone and basalt lithologies in Washington State, USA. Contributing source areas were delineated for each feature using a digital elevation model (DEM) as well as a Global Positioning System device in the field. Systematic source area slope relationships described in other landscapes were not evident for channel heads in either lithology. In addition, substantial variability in DEM derived source area sizes relative to field delineated source areas indicates that in this area, identification of an area slope relationship, should one even exist, would be difficult. However, channel heads and stream heads, here defined as the start of perennial flow, appear to be co located within both of the lithologies, which together with lateral expansion and contraction of surface water around channel heads on a seasonal cycle in the basalt lithology, suggest a controlling influence of bedrock springs for that location. While management strategies for determining locations of channel heads and perennial flow initiation in comparable areas could assign standard source area sizes based on limited field data collection within that landscape, field mapped source areas that support perennial flow are much smaller than recognized by current Washington State regulations.
RESTTESTGEN: Automated Black Box Testing of RESTful APIs
Venue: 2020 IEEE 13th International Conference on Software Testing, Validation and Verification (ICST)
Year: 2020

RESTful APIs (or REST APIs for short) represent a mainstream approach to design and develop Web APIs using the REpresentational State Transfer architectural style. When their source code is not (or just partially) available or the analysis across many dynamically allocated distributed components (typical of a micro services architecture) poses obstacles to white box testing, black box testing becomes a viable option. Black box testing, in fact, only assumes access to the system under test with a specific interface. This paper presents RESTTESTGEN, a novel approach to automatically generate test cases for REST APIs, based on their interface definition (in Swagger) Input values and requests are generated for each operation of the API under test, with the twofold objective of testing nominal execution scenarios and of testing error scenarios. Two distinct oracles are deployed to detect when test cases reveal implementation defects. Our empirical investigation shows that this approach is effective in revealing actual faults on 87 real world REST APIs.
In situ construction of g C3N4/g C3N4 metal free heterojunction for enhanced visible light photocatalysis.
Venue: ACS applied materials interfaces
Year: 2013

The photocatalytic performance of the star photocatalyst g C3N4 was restricted by the low efficiency because of the fast charge recombination. The present work developed a facile in situ method to construct g C3N4/g C3N4 metal free isotype heterojunction with molecular composite precursors with the aim to greatly promote the charge separation. Considering the fact that g C3N4 samples prepared from urea and thiourea separately have different band structure, the molecular composite precursors of urea and thiourea were treated simultaneously under the same thermal conditions, in situ creating a novel layered g C3N4/g C3N4 metal free heterojunction (g g CN heterojunction) This synthesis method is facile, economic, and environmentally benign using easily available earth abundant green precursors. The confirmation of isotype g g CN heterojunction was based on XRD, HRTEM, valence band XPS, ns level PL, photocurrent, and EIS measurement. Upon visible light irradiation, the photogenerated electrons transfer from g C3N4 (thiourea) to g C3N4 (urea) driven by the conduction band offset of 0.10 eV, whereas the photogenerated holes transfer from g C3N4 (urea) to g C3N4 (thiourea) driven by the valence band offset of 0.40 eV. The potential difference between the two g C3N4 components in the heterojunction is the main driving force for efficient charge separation and transfer. For the removal of NO in air, the g g CN heterojunction exhibited significantly enhanced visible light photocatalytic activity over g C3N4 alone and physical mixture of g C3N4 samples. The enhanced photocatalytic performance of g g CN isotype heterojunction can be directly ascribed to efficient charge separation and transfer across the heterojunction interface as well as prolonged lifetime of charge carriers. This work demonstrated that rational design and construction of isotype heterojunction could open up a new avenue for the development of new efficient visible light photocatalysts.
