A Multi-stage Model Based on Association Rule Analysis for Forecasting and Modifying Electricity Demand and Price in a Smart Grid
Authors: Liu Huan  , Han Ying-Hua  , Liu Jiao-Rao
Published: February 2025

Smart electricity grids are continuously being deployed to enable utilities, customers and third-party providers to monitor and control energy usage. The aggregate reaction of consumers can potentially shift the demand curve. Data collected by the smart grid will provide several advantages to all participants, including better decision-making regarding energy-usage and enhanced understanding of consumer decisions. In this paper, a multi-stage forecasting framework is proposed for forecasting and modifying electricity demand, which contains three stages: Initial Forecasts Manufacturer (IFM), Extracted Rules Manufacturer (ERM) and Modified Forecasts Manufacturer (MFM). In the proposed model, a fuzzy neural network is used to generate the initial price and demand forecasts in IFM. During ERM, the proposed Apriori-AND algorithm is used to detect and extract price-demand dynamics. Finally, the Multi-valued Logic method is used to modify the initial forecasts by using the rules extracted in MFM. The model will further improve the prediction accuracy by using association rule analysis. The simulation results are generated with historical data.

Fault Propagation Analysis with Uncertain Parallel Reasoning for Process Safety
Authors: Hu Jin-Qiu  , Zhang Lai-Bin  , Cai Shuang
Published: February 2025

An uncertain parallel reasoning method is proposed for fault propagation in the refining process in order to determine and prevent fault propagation. A fuzzy petri net (FPN) was employed to develop the fault propagation model. Based on expert analysis, uncertain parallel reasoning was employed to identify the fault root of abnormal situations. The basic event was assigned the largest fault probability, and the event directly affected by the basic event was also indicated. Therefore, the most likely fault propagation path was identified by analyzing the relations between faults. A case study is presented based on an atmospheric tower device, which is commonly used in a typical refining process. The uncertain parallel reasoning method was employed to analyze fault propagation in the atmospheric tower system; results indicate that the most likely fault propagation path is as follows: abnormal feed temperature → abnormal temperature in the atmospheric tower bottom → unqualified product quality → entirely failure of the atmospheric tower.
Distributed Diffusion-scheme ECME Estimator for Distributed Estimation in Wireless Networks
Authors: Li Xiao-Fei  , He Di  , Hung Ching-Jer
Published: February 2025

This paper presents Distributed Diffusion Expectation Conditional Maximization Either (DDECME) estimator for Gaussian mixture over wireless sensor network. The main novelty of DDECME estimator with respect to the existed schemes resides in the fact that the propagation of information across the network consumes less time to be embedded in the iterative updating of the parameters, where DDECME estimator adopts the conditional maximized incomplete-data likelihood function to replace the M-steps of DDEM estimator. Numerical examples show that the proposed algorithm practically consumes less time to attain lower NMSE and BER while each node maintains the estimated performance and compares favorably with other estimators.
Positioning Commercial Pedometers to Measure Activity of Older Adults with Slow Gait: At the Wrist or at the Waist?
Authors: Ehrler Frederic  , Weber Chloe  , Lovis Christian
Published: February 2025

Sedentary behaviour is a major risk factor for chronic disease morbidity and mortality in aging. Measuring people activity through devices such as pedometers is a recognized intervention to motivate them for more physical activity. However, the feedback provided by these devices must be accurate in order to avoid overtraining and keep users' motivation alive. If the accuracy of pedometers has been validated for healthy people, their lack of accuracy for elderly people walking at slower pace has been reported in several studies. The emergence on the consumer's market of new devices that can be worn indifferently at the wrist or at the waist raises once more this concern. In order to evaluate whether pedometers' location influences their accuracy, we have tested three pedometers at different locations, and for several paces in a comparative study. Beyond confirming the decrease of pedometers' accuracy with speed reduction, our study reveals that pedometers should be worn at the waist rather than at the wrist. This leads us to recommend wearing pedometers at the waist when monitoring population with reduced mobility.

Going Beyond Systematic Reviews: Realist and Meta-Narrative Reviews
Authors: Otte-Trojel Terese  , Wong Geoff
Published: February 2025

Health information technologies are complex interventions whose effects differ across contexts. To improve our understanding of the effects of health information technologies, approaches are needed that utilize evidence beyond experimental results in order to provide explanatory answers to how and why a given technology works. The relatively new realist and meta-narrative review approaches are introduced as important methods in synthesising and analysing evidence in the field of health informatics. A common purpose of these two review approaches is to help create a sense of evidence about complex interventions that enables an understanding of how and why they work. A detailed description of the principles and objectives of the two types of reviews is presented. Key steps required to conduct each of the reviews are summarized, and examples of how the review approaches have been applied to topics related to health informatics are provided. Limitations of the two review approaches are discussed.
Publishing Health IT Evaluation Studies
Authors: Ammenwerth Elske  , de Keizer Nicolet F.
Published: February 2025

Progress in science is based on evidence from well-designed studies. However, publication quality of health IT evaluation studies is often low, making exploitation of published evidence within systematic reviews and meta-analysis a challenging task. Consequently, reporting guidelines have been published and recommended to be used. After a short overview of publication guidelines relevant for health IT evaluation studies (such as CONSORT and PRISMA), the STARE-HI guidelines for publishing health IT evaluation studies are presented. Health IT evaluation publications should take into account published guidelines, to improve the quality of published evidence. Publication guidelines, in line with addressing publication bias and low study quality, help strengthening the evidence available in the public domain to enable effective evidence-based health informatics.
Forward Outlook: The Need for Evidence and for Action in Health Informatics
Authors: Rigby Michael  , Ammenwerth Elske  , Talmon Jan
Published: February 2025

Evidence-based health informatics (EBHI) is a key concept in the development and deployment of IT systems and applications in an ethical, efficient and effective health system. There is an ever growing body of knowledge to guide IT-related decision making, but further growth of this body of knowledge is required as the health IT domain and technologies are continuously evolving, leading to new functionalities and applications. However, EBHI should not wait until retrospective evidence is available – increasingly policy makers should draw on available prior and external evidence to influence design and development processes so as to ensure that health IT is devised in response to a delivery process need and not as an IT driven goal. EBHI should thereby seek to move forward significantly the metric that only some 20% of IT investment is truly successful.

Authors: Tan Yi-Fei  , Lam Hai-Shuan  , Azlan Asyraf  , Soo Wooi-King
Published: February 2025

Malaysians are actively expressing feelings and opinions on social networks such as Twitter. These expressions can be harvested for studying the customer sentiments towards certain brands and preferences of customers. As business analytics becoming more important, sentiment analysis may provide crucial information in making customer-driven decisions. Therefore, accuracy is critical in determining the reliability and integrity of the analysis. Although, processing massive messages on social media is a huge challenge, it is now made easier by the advancement of the big data architecture. There are many techniques in interpreting these messages. However, Malaysians consists of people from very diversified backgrounds with a multitude of cultures and languages in daily use. Therefore, it is very common to find messages on social media with mixture of various local languages and slangs. The slangs used are mostly dialects expressed with alphabets. This project explores the techniques on analyzing the popularity of 5 telecommunication companies in Malaysia and addresses the shortfalls of using the existing English sentiment dictionary. With the accomplishment of this project, a new localized dictionary is developed by compiling various mixtures of English, Malay localized sentiwords and slangs into the dictionary. The new dictionary is proven to capture and analyze 30% extra keywords on the Malaysian tweets sampled. These additional matches will improve the accuracy compared to existing dictionaries.

Authors: Chung In-Hang  , Huang Kun-Shu  , Hwang Chi-Kuang  , Yen Ming-Ching  , Wang Chih-Hu  , Tien Ching-Cheng
Published: February 2025

Framed Slotted Aloha (FSA) protocols have been widely used in diverse multiple access communication systems. Consider an FSA system that consists of pre-specified users and there is assignable number of slots accommodated in a frame. Each user will randomly transmit a packet in one of the assigned slots. Characterizing the probability for the event that an exact number of collided slots occurs in a frame, is an important issue for some FSA protocols based networks, e.g., RFID networks. In this paper, we propose a generic analytical approach (GAA) to evaluate the above characterized probability of FSA systems by using the principle of inclusion and exclusion. Accuracy of the ECFF is validated via simulations. We believe that major contributions of this paper can provide valuable method for the evaluation of the characterized probability in a variety of FSA protocols based applications.

Published: February 2025

Integrated care and connected health are two fast evolving concepts that have the potential to leverage personalised health. From the one side, the restructuring of care models and implementation of new systems and integrated care programs providing coaching and advanced intervention possibilities, enable medical decision support and personalized healthcare services. From the other side, the connected health ecosystem builds the means to follow and support citizens via personal health systems in their everyday activities and, thus, give rise to an unprecedented wealth of data. These approaches are leading to the deluge of complex data, as well as in new types of interactions with and among users of the healthcare ecosystem. The main challenges refer to the data layer, the information layer, and the output of information processing and analytics. In all the above mentioned layers, the primary concern is the quality both in data and information, thus, increasing the need for filtering mechanisms. Especially in the data layer, the big biodata management and analytics ecosystem is evolving, telemonitoring is a step forward for data quality leverage, with numerous challenges still left to address, partly due to the large number of micro-nano sensors and technologies available today, as well as the heterogeneity in the users' background and data sources. This leads to new R&D pathways as it concerns biomedical information processing and management, as well as to the design of new intelligent decision support systems (DSS) and interventions for patients. In this paper, we illustrate these issues through exemplar research targeting chronic patients, illustrating the current status and trends in PHS within the integrated care and connected care world.

Authors: Vähäaho Ilkka  , Kangas Heikki  , Takahashi Hidenori  , Kitazume Masaki
Published: February 2025

When a group column type improved ground consisted of treated clay columns and soft clay is subjected to overburden pressure, the ground settlement takes place much faster than that of unimproved ground. This phenomenon is considered due to high permeability of treated column in Nordic countries. In Japan, on the other hand, it is considered due to high compressibility of treated column. In this study, the permeability of treated clays and the consolidation phenomenon of the improved ground were investigated by a series of element oedometer tests and permeability tests, and model consolidation tests and numerical analyses, and by analyzing long time follow-up observations from site. It was found that the permeability coefficient of cement treated clays decreased slightly with increasing the amount of cement, while this phenomenon was not confirmed in lime treated. Based on the investigations on consolidation of the improved ground, it was found that the consolidation phenomenon was much influenced by not only the permeability but also the compressibility of the treated column. This study revealed that the consolidation of the column type improved ground with high compressibility of column proceeded faster that that of unimproved ground even if the permeability of the column is lower than that of the untreated clay.

Authors: Shroff A.V.  , Patel B.R.
Published: February 2025

An improvement in the bearing capacity and reduction in settlement of soft deposits can be effected by the installation of stone column. The cost consideration for utilizing the poor and marginal sites efficiently have therefore becomes a subject of profound interest for the employment of stone column. The stone columns provide strength reinforcement to the soil and due to their relatively high modulus, a large portion of the load applied to the ground surface is transferred to them. The stone columns act as vertical drains and accelerate consolidation. From the economic point of view Composite Stone Column and Floating Stone Column gives saving of about 30 % in stone aggregate, besides marginal reduction in ultimate load capacity. i.e. 0.56 % and 1.13 %, respectively.

Authors: Ng C.W.W.  , Lee C.J.  , Xu G.M.  , Zhou X.W.
Published: February 2025

It is not unusual to observe inclination of buildings and towers as a result of unwanted differential foundation settlements. Over the years, a number of different engineering solutions including the method of soil extraction have been attempted to reduce unexpected inclination of buildings and towers. By using a state-of-the-art robotic manipulator, a series of novel centrifuge model tests conducted to investigate key factors which govern the restoration of building tilts are described and reported. In the centrifuge simulation tests, the robotic manipulator was used to core and extract soil in-flight near an initially tilted model building. This soil extraction was to induce stress release, thereby mitigating the inclination of the building. Effects of different configurations and sequences of drilling on results of restoration were investigated in the centrifuge.

Bored, continuous flight auger and omega instrumented piles: Behavior under compression
Authors: Albuquerque P.J.R.  , Carvalho D.  , Massad F.
Published: February 2025

This paper presents a study on the behavior under compression of three types of piles, built in the Experimental Field for Foundations and Soil Mechanics of the UNICAMP University. Three piles of each type were built: bored (without the use of bentonite slurry), continuous flight auger (CFA) and omega. Nominal diameters of the piles were 0.40 m, 0.40 m and 0.36 m, respectively, all of them 12 m in length. Local subsoil is characterized as a diabase type soil. The first layer (0 to 6 m) is a collapsible silty sandy clay, followed by clayey sandy silt (6 to 18 m). Water level is only reached at 17 m. The piles were instrumented along their depth with electric extensometers (strain gauges), installed at 0.30 m (section of reference), 5.0m, 11.1m and 11.7m. Instrument data indicated that all the piles behaved as friction piles: in average, the tip reaction reached 2% of the total applied load for the bored piles; 7% for the CFA piles and roughly 14% for the omega piles. In the same order, the mean ultimate load test values for the SML tests were 682kN, 885kN and 1,428kN.

Authors: Maia Paulo C.A.  , Barros Rodrigo A.  , Saboya Fernando
Published: February 2025

This paper shows experimental results of settlement measurements of a residential building during construction. The foundation is composed by deep continuous auger pile. The foundation strata is basically constituted by soft/loose soils. Important aspects are pointed out regarding soil-structure interaction and its influence on mechanical response of the building. A brief description of the surveying methodology is presented. The evaluation of the loading in the foundation was done by a three dimensional numerical model. Two different mechanical approaches were considered: fixed foundation (no movements) and one dimensional movements foundation, where the foundation is considered to displace in vertical direction only. The soil-structure interaction was assessed by comparison the measured settlements against the loads obtained through two approaches considered. These results allowed the evaluation of factors that play important role on the load re-distribution due to soil-structure interactions, mainly the increase of structure rigidity.

Optimizing foundation piling
Authors: Senapathy Harish  , Davie John R.  , Clemente José L.M.
Published: February 2025

The design estimation of the required piling dimensions for a project is a multiple step process that lends itself to optimization. The estimate of required piling dimensions made during the design phase of a project is typically based on published design references. Most commonly, the estimated length of the pile is dictated by the compression load and site subsurface conditions. Although much effort has been devoted to developing equations that optimize the design of the piles, these design phase estimates, in the authors' experience, most often use the engineer's preferred method, and are just the initial steps in the foundation optimization process. The best opportunity to optimize the pile dimensions occurs during pre-production load tests. Based on experience, the authors describe a series of steps used to optimize piling requirements for a project.

Seismic earth pressure including soil cohesion
Authors: Ortigosa P.
Published: February 2025

Normally, seismic earth pressures against retaining structures are computed assuming zero cohesion in the retained soil. This criteria is supported on seismic strains in the retained soil which can destroy the soil cohesion, ending with a pure frictional material. However, it is possible to establish a strain dependent variation for the soil cohesion and the soil angle of friction as well as a relationship between the horizontal seismic displacement of the retaining structure and the strain of the retained soil. By combining these parameters it is possible to define the cohesion to be used in the design. This methodology is illustrated for a cantilever retaining wall with a silty sand from volcanic origin (pumice) used as fill material.
Influence of compaction condition on the microstructure of a non-plastic glacial till
Authors: Davoudi M.H.  , Lefebvre G.
Published: February 2025

The influence of compaction water content on the structure has been well known for clayey soils, but has never been studied for granular materials. In this paper the effect of compaction moisture on the structure of a non-plastic till is investigated by means of scanning electron microscopy, water retention curve, permeability and mercury intrusion porosimetry tests. The results show that the structure of pulverulized materials, in some degrees similarly to cohesive materials, is affected by the compaction condition. When compacted on the dry side of the optimum water content, the porous system is characterized by a relatively uniform medium pores, while in case of compaction on the wet side, due to formation of coarse aggregates, pores size is very diversified. The few large pores are surrounded by numerous small pores, and the hydraulic behavior of the porous system of the soil is dominated by the small pores.

Authors: Dimitrievski Lj.  , Tomov S.
Published: February 2025

This paper deals with the problem of soil improvement using geosynthetics and substitution of the loose sand and soft clay with coarse gravel having good soil mechanics characteristics. High ground water at 1 m below the ground surface, the anticipated earth-quake of 9 degrees MCS intensity scale, liquefaction potential and heavy weight of the structure are the reasons for this soil improvement technique to be analytically examined in relation to the soil-structure interaction. Analysis has been performed using Plaxis software under static as well as earthquake conditions. By using the stress-strain analysis, forces in the geogrid and settlements have also been calculated. Earthquake loading case and the results from the analysis are discussed in details and the use of the geosynthetics has been approved.

Published: February 2025

Finite element analyses based on infinitesimal deformation and finite deformation theories are carried out to investigate the mechanism of the localized deformation of normally and over consolidated clays in drained shear tests. For this purpose, an isotropic hardening elastoplastic model for soils, named subloading tij-model, is used in the analysis. Two different geometrical conditions are assumed. – plane strain condition (2D) and triaxial condition (3D). The developments of shear bands in clays in these conditions are well simulated by the present finite element analyses.

In this paper finite element analyses of deep excavations in soft ground in the city of Salzburg, Austria are presented. The regional subsoil situation in Salzburg can be described as fully saturated soft clay (referred to as “Seeton”) overlain by a quaternary gravel fill. The poorly graded Seeton can be classified as fine silt or fine sand respectively and shows unfavourable soil properties with respect to the deformation behaviour of deep excavations. Common calculation methods for retaining structures based on failure criterions like Mohr-Coulomb cannot take into account this complex behaviour adequately. Therefore more advanced constitutive models have been used in analysing two different deep excavations in Salzburg. Firstly the Hardening Soil model, an isotropic double hardening model as implemented in the commercial version of finite element code Plaxis and secondly a newly developed constitutive model based on the multilaminate concept. The comparison with in situ measurements showed that both models are capable of representing the behaviour of soft soils, at least for this type of problems.

This study proposes MFER design, an international standard for saving measured vital signs while simultaneously monitoring, for health care. The proposed method does not record vital signs as a single file, but rather, after setting header information on vital signs, it reads the measured signs in regular intervals, which are shown in a screen and saved along with header information. Shorter the interval of saving, more similar it becomes to real time monitoring. After measurement is complete, the file fragments are aggregated into a single file, including the header information. MFER constructed in this study in real time monitoring design shows that it can be efficiently used in monitoring and saving of vital signs for health care.
National eHealth Implementation: Country Experience
Authors: Hardardottir Gudrun Audur  , Thoroddsen Asta
Published: February 2025

A national eHealth strategy is presumed to empower health professionals, patients and citizens to increase patient safety and quality of health care delivery. A national eHealth infrastructure encompassing a secure HealthNet, interconnected electronic health records, e-prescriptions, a national medication database and a patient portal has been implemented in Iceland. The timely and secure access to patient information by health professionals through a single portal, independent of where the patient received care, is expected to increase continuity of care, decrease duplication of data and tests, increase efficiency, increase cost effectiveness and benefit citizens in several ways. The eHealth strategy needs to be evaluated using comparable indicators.
Evolving National Strategy Driving Nursing Informatics in New Zealand
Authors: Honey Michelle  , Westbrooke Lucy
Published: February 2025

An update to the New Zealand Health Strategy identifying direction and priorities for health services is underway. Three specific areas have implications for nursing informatics and link to education and practice: best use of technology and information, fostering and spreading innovation and quality improvements, and building leaders and capability for the future. An emphasis on prevention and wellness means nursing needs to focus on health promotion and the role of consumers is changing with access to their on-line information a major focus. As the modes of delivery for services such as telehealth and telenursing changes, nurses are increasingly working independently and utilizing information and communication technologies to collaborate with the health team. New Zealand, and other countries, need strong nursing leadership to sustain the nursing voice in policy and planning and ensure nurses develop the required informatics skills.

We present one part of the results of an international survey exploring current and future nursing informatics (NI) research trends. The study was conducted by the International Medical Informatics Association Nursing Informatics Special Interest Group (IMIA-NISIG) Student Working Group. Based on findings from this cross-sectional study, we identified future NI research priorities. We used snowball sampling technique to reach respondents from academia and practice. Data were collected between August and September 2015. Altogether, 373 responses from 44 countries were analyzed. The identified top ten NI trends were big data science, standardized terminologies (clinical evaluation/implementation), education and competencies, clinical decision support, mobile health, usability, patient safety, data exchange and interoperability, patient engagement, and clinical quality measures. Acknowledging these research priorities can enhance successful future development of NI to better support clinicians and promote health internationally.
Issues for Deployment of Mobile Learning by Nurses in Australian Healthcare Settings
Authors: Mather Carey  , Cummings Elizabeth
Published: February 2025

Undergraduate nursing curricula are being redesigned to include strategies for deployment of mobile learning as a legitimate nursing function. A recent online survey exploring the use of mobile learning by undergraduate student nurses revealed barriers, challenges, risks, and benefits to using mobile learning at the workplace. Inability to access mobile learning at both individual and organisational levels impacted on student learning and teaching opportunities. Students also indicated that educational preparation for ensuring appropriate use of mobile learning is necessary to guide learning and teaching in situ at point of care. This highlights the need for the development of policy to guide best practice that will enable this new pedagogy to be fully utilised for learning and teaching in healthcare settings. Until governance of mobile learning in educational and healthcare settings in Australia is addressed, harnessing the indubitable benefit of mobile learning and teaching will be unachievable.
Online Information Seeking Behaviour by Nurses and Physicians: A Cross-Sectional Study

Published: February 2025

Online bibliographic databases constitute the access to information supporting evidence-based practice. The purpose of the present survey is to evaluate the awareness, the use and the impact that online evidences have in clinical practice. An online survey was conducted using a 25 item questionnaire which was completed by 263 healthcare practitioners (nurses and doctors). Chi-square analysis and t-tests were used and comparisons between both groups were made. Multiple logistic regression to predict databases use was employed. Ninety-three percent (n = 206) of participants had heard about the online bibliographic databases; 5.7% of participant sample have heard about online databases but they do not use them. 18.3% was the total sample of non-users (n = 48). The main reason of using was filling a knowledge gap (50.7%), and the main reasons of not using were both that they use another information source and they don't need them to do their job. Both nurses and doctors believe that the use of online databases improves patient care it is a part of their legitimate clinical role. They need more training to improve their searching skills, enhancing them in everyday clinical place.
Clustering the Whole-Person Health Data to Predict Liver Transplant Survival

Published: February 2025

This study aims to discover groups (clusters) of patient who share whole-person characteristics. An unsupervised clustering analysis using a hierarchical agglomerative approach was applied to identify meaningful groups of patient characteristics. Results showed that is possible to identify clusters that have similar patient characteristics, and that these characteristics may be associated with survival.
