Full textAbstract:
The volume of transaction data in the banking industry is growing with the increase in customers and transaction complexity. Ineffi-cient data management can lead to server overload, affect system performance, and hinder the delivery of fast, accurate services. Housekeeping processes are needed to move inactive data to sepa-rate storage, allowing the main server to function more efficiently. Pentaho Data Integration (PDI) offers an effective solution for man-aging the ETL (Extract, Transform, Load) process, which is crucial for data housekeeping. This research aims to optimize the manage-ment of banking transaction data using PDI to reduce server load and improve operational efficiency. This quantitative study applies an experimental method, with the ETL process managing Bank XYZ’s transaction data older than six months. The study uses trans-action data from Bank XYZ’s MySQL server, which will be trans-ferred to a data warehouse. The analysis applies clustering algo-rithms to filter and separate active from inactive transactions. The implementation of PDI for housekeeping effectively reduces server load and improves data management efficiency, significantly lower-ing processing time. The combined use of clustering algorithms and PDI delivers substantial improvements in managing banking transac-tion data, enhancing operational efficiency while significantly re-ducing the load on the main server

Full textAbstract:
In this article, we analysed the problems of electronic medical records (EMRs) and found that the EMRs generated by different hospitals for the same patient are mutually independent and duplication and data sharing are difficult among hospitals. In order to solve this problem, this paper proposes an efficient and secure cross-domain sharing scheme of EMRs based on edge computing. The program allows the doctor to access the personal history EMRs through the patient’s authorization so that the doctor can understand the patient’s history of illness and, on this basis, generate a new medical record for the patient. Then, the doctor sends the EMRs to the edge server, and the server calculates the ciphertext and adds it to the patient’s personal medical record to complete the case update. Analysis shows that this solution can effectively prevent data tampering and forgery through blockchain and avoid privacy leakage problems in plaintext sharing by using searchable encryption and by relying on edge servers to solve nearby computing tasks and divert the computing capacity of cloud servers to improve efficiency. The security proof shows that the scheme satisfies the complex problem of the BDH assumption. Performance analysis shows that the scheme is feasible and efficient.

Full textAbstract:
Electronic health records (EHRs) have become a popular method to store and manage patients’ data in hospitals. Sharing these records makes the current healthcare data management system more accurate and cost-efficient. Currently, EHRs are stored using the client/server architecture by which each hospital retains the stewardship of the patients’ data. The records of a patient are scattered among different hospitals using heterogeneous database servers. These limitations constitute a burden towards a personalized healthcare, when it comes to offering a cohesive view and a shared, secure and private access to patients’ health history for multiple allied professionals and the patients. The data availability, privacy and security characteristics of the blockchain have a propitious future in the healthcare presenting solutions to the complexity, confidentiality, integrity, interoperability and privacy issues of the current client/server architecture-based EHR management system. This paper analyzes and compares the performance of the blockchain and the client/server paradigms. The results reveal that notable performance can be achieved using blockchain in a patient-centric approach. In addition, the immutable and valid patients’ data in the blockchain can aid allied health professionals in better prognosis and diagnosis support through machine learning and artificial intelligence.

Full textAbstract:
The front-end bottleneck is a well-established problem in server workloads owing to their deep software stacks and large instruction footprints. Despite years of research into effective L1-I and BTB prefetching, state-of-the-art techniques force a trade-off between metadata storage cost and performance. Temporal Stream prefetchers deliver high performance but require a prohibitive amount of metadata to accommodate the temporal history. Meanwhile, BTB-directed prefetchers incur low cost by using the existing in-core branch prediction structures but fall short on performance due to BTB’s inability to capture the massive control flow working set of server applications. This work overcomes the fundamental limitation of BTB-directed prefetchers, which is capturing a large control flow working set within an affordable BTB storage budget. We re-envision the BTB organization to maximize its control flow coverage by observing that an application’s instruction footprint can be mapped as a combination of its unconditional branch working set and, for each unconditional branch, a spatial encoding of the cache blocks around the branch target. Effectively capturing a map of the application’s instruction footprint in the BTB enables highly effective BTB-directed prefetching that outperforms the state-of-the-art prefetchers by up to 10% for equivalent storage budget.

Full textAbstract:
To assist a solution to the problem of the test environment spanning multiple platforms, this paper proposes a decision support framework with the blackboard model to integrate all complementary features into a single automated test environment for multi-platform client/server applications. Before testing client/server applications, the input into this framework are testing tools with different approaches and client sites which are going to run the test. The planning agent will make a decision dynamically and produce a testing plan to allocate testing tasks to these testing tools to client sites. Two complementary features for testing client/server applications are illustrated in this paper to demonstrate how the framework works. The concept of mobile agents is applied to launch the test driver to different client sites, execute the tests and bring back the test results from client sites as well as the trace file from the server site for inspecting the interaction behavior among clients. Based on the multicast framework, the same test data can be broadcasted to multiple clients sites to run the tests simultaneously and the test results can be returned from client sites for examining the problem of repeated executions.

Full textAbstract:
The efficiency of the current cellular network is limited due to the imbalance between resource availability and traffic demand. To overcome these limitations, baseband units (BBUs) are deployed on virtual machines (VMs) to form a virtual pool of BBUs. This setup enables the pooling of hardware resources, reducing the costs associated with building base stations (BSs) and simplifying both management and control. However, extreme levels of server resource use within the pool can increase physical maintenance costs and impact virtual BBU performance. This study introduces an adaptive, threshold-based dynamic migration strategy for virtual BBUs within the iCanCloud framework by setting upper and lower limits on the servers’ resource usage in the pool. The proposed method determines whether to initiate a migration by evaluating resource usage on each compute node and identifies the target node for migration if required. This aims to balance server load and cut energy consumption, and also to avoid unnecessary migration because of too high or too low server load, and effectively determine the time to trigger migration and not depend only on a certain instantaneous peak of server resource utilization. This paper used a deep Q-network learning method to predict resource utilization and make an accurate migration decision based on a history dataset. Experimental results show that as compared with Kalman filter prediction and other traditional methods, this model can effectively lower the cost of VM migration by decreasing the migration time and occurrence of it to enhance overall performance while reducing energy consumption.

The Ishihara method is one way to detect whether or not someone suffers from color blindness. This method possesses several sets of plates or circle patterns containing various combinations of colored dots and sizes, forming numbers visible for people with normal eyes. A collection of several plates with the name Ishihara book is available in the market. However, the book has a weakness for being easily damaged or faded in color. Although there are some shortcomings, several researchers have developed applications to anticipate those weaknesses. Being unable to be used by several people at once and the test history has not been adequately archived, are several examples of shortcomings of existing applications. This study aims to create a client-server-based color blindness testing mobile application. The system can provide real-time test results, and detailed test history is presented. Another feature is the push notification menu that sends messages to all users. This application has been designed and implemented successfully. Thereby, it can be used for a color blindness test before conducting a medical examination.

Full textAbstract:
Data congestion and network delay are the important factors that affect performance of cloud computing systems. Using local disk of computing nodes as a cache can sometimes get better performance than accessing data through the network. This paper presents a storage cache placement algorithm—C-Aware, which traces history access information of cache and data source, adaptively decides whether to cache data according to cache media characteristic and current access environment, and achieves good performance under different workload on storage server. We implement this algorithm in both simulated and real environments. Our simulation results using OLTP and WebSearch traces demonstrate that C-Aware achieves better adaptability to the changes of server workload. Our benchmark results in real system show that, in the scenario where the size of local cache is half of data set, C-Aware gets nearly 80% improvement compared with traditional methods when the server is not busy and still presents comparable performance when there is high workload on server side.

The credibility of a hospital has the effect of the services provided by the hospital. One of the services in the hospital is inpatient services and the role of nurses who have an important role in serving patients. Some problems in hospitalization services that occur such as manual nurse calls are done by visiting the treatment room and proposing the desired service. This method is less effective because it will require a long process in service. The application of nurse calls is done to improve services so that nurses can provide the best service and patient health can be monitored properly. The calling system for nurses is based on client-server and additional features such as heart detection, temperature detection, and emergency buttons that have the role to call nurses. The advantage of the nurse call application is that it can monitor patient health from several detection devices that will automatically call through the application. In addition to handling patients will be monitored by the hospital, the nurse's performance will also be detected. The results of this study are that the nurse call process will be automatically carried out by a detection device so that the nurse will detect the patient's condition quickly, the patient handling data will be stored on the server, therefore the history of heart rate and temperature records is more complete and can be used for doctors to handle patients.

The increasing need for traffic detection system has become a vital area in both developing and developed countries. However, it is more important to get the accurate and valuable data to give the better result about traffic condition. For this reason, this paper proposes an approach of tracking traffic data as cheap as possible in terms of communication, computation and energy efficient ways by using mobile phone network. This system gives the information of which vehicles are running on which location and how much speed for the Traffic Detection System. The GPS sensor of mobile device will be mainly utilized to guess a user’s transportation mode, then it integrates cloud environment to enhance the limitation of mobile device, such as storage, energy and computing power. This system includes three main components: Client Interface, Server process and Cloud Storage. Some tasks are carried out on the Client. Therefore, it greatly reduces the bottleneck situation on Server side in efficient way. Most of tasks are executed on the Server and history data are stored on the Cloud Storage. Moreover, the paper mainly uses the distance based clustering algorithm in grouping mobile devices on the same bus to get the accurate data.

<span>A Web server log files contain an entire record of the user’s browsing history such as referrer, date and time access, path, operating system (OS), browser and IP address. User navigation pattern discovery involves learning of user’s browsing behaviour to gain the pattern from web server log file. This paper emphasizes on identifying user navigation pattern from web server log file data of iLearn portal. The study implements the framework for user navigation including phases of acquisition of weblog, log query parser, preprocessor, navigational pattern modelling, clustering, and classification. This study is conducted in the context of the actual data logs of the iLearn portal of Universiti Teknologi MARA (UiTM). This study revealed the navigational patterns of online learners which relatively related to their intake or group along the semester of 14 weeks. Besides, access patterns for students along the semester are different and can be classified into three (3) quarter, namely Q1, Q2 and Q3 based on the total of week per semester. Future work will focus on the development of prototype to improve the security of online learning especially during the assessment progress such as online quiz, test and examination.</span>

Full textAbstract:
This study proposes a user visit certification and visit trace system using inaudible frequencies in the range of audible frequencies but not those audible to people. The signal frequency consists of inaudible frequencies in the range of 18 kHz to 20 kHz, which can be generated by normal speakers. This system recognizes the signal frequency and sends signal values, users’ IDs, and location information to a server to certify the current user’s location. The server categorizes and stores the user’s visit history by individual, and the user can check their personal visit trace information in the application. To verify the utility of the proposed system, we developed an application for user certification and tracing based on a smart device and a built server system. We conducted user certification and trace experiments using the proposed system, resulting in 99.6% accuracy. As a comparative experiment, we conducted a visit certification experiment using a QR code and the proposed system and found that the proposed system performed better. Thus, the proposed system will be a useful technology for epidemiological surveys for individual users and electronic entry lists to restaurants and facilities in the age of COVID-19.

Full textAbstract:
This paper presents the design and prototype execution of a new home automation system that connects its components using Wireless-Fidelity (Wi-Fi) technology. The system under consideration comprises two primary parts. The first element is the web server, which serves as the system core and is responsible for managing, controlling, and keeping an eye on users' homes. Remotely using the internet and locally using a Local Area Network (LAN) the user and system administrator can manage and control the system code. The hardware interface part is the second element which acts as an interface between sensors and actuators. The proposed system is more scalable since it can manage many hardware modules available in Wi-Fi coverage using a single server. The system which is proposed in this paper outperforms the recently proposed home automation systems in terms of scalability and flexibility.

In recent years, the natural history collections community has made great progress in accelerating the pace of collection digitization and global data-sharing. However, a common workflow bottleneck often occurs in that period immediately following image capture but preceding image submission to portals, a critical phase involving quality control, file management, image processing, metadata capture, data backup, and monitoring performance and progress. While larger institutions have likely developed reliable, automated workflows over time, small and medium institutions may not have the expertise or resources to design and implement workflows that take full advantage of automation opportunities. Without automation, these institutions must invest many hours of manual effort to meet quality and performance goals. To address its own needs, BRIT developed a number of workflow automation components, which coalesced over time into a suite of tools that operate on both an image capture station as a client application and on a server that provides file storage and image processing features. Together, these tools were created to meet the following goals: Simplify file management and data preservation through automation Quickly identify quality issues Quickly capture skeletal metadata to facilitate later databasing Significantly reduce time between image capture and online availability Provide performance and quality monitoring and reporting Easy configuration and maintenance of client and server The client and server components together can be considered a “digitization appliance”: software integrated with the specific goal of providing a comprehensive suite of digitization tools that can be quickly and easily deployed on simple consumer hardware.

a Speech Recognition is a system used to recognize word commands from human voices and then translated them into data that can be understood by a computer. The advantages of Speech Recognition include speed and ease of use. Merdeka Malang is a private university founded on January 29, 1964. The University of Merdeka Malang still doesn’t have a strategy in recommending new students based on historical data calculations in choosing faculties. and majors. In calculating the history, if you use a manual system, they will be constrained by the time and accuracy of the data, causing the data to be less valid.Therefore, there is a need for a system that can exchange data in real-time so that the data displayed is always up to date without manual data updating. This process is useful for monitoring and accelerating the process of calculating student interest data, which can later be recommended to future new students. Moreover, The speech technique used is using speech recognition which is used for processing speech data on smartphones while sending data using the XAMPP web server which is used to exchange data from smartphones to servers.

Significant exploitation and utilization of cloud computing in industry is come with and in the identical time vulnerable by unease regarding protection of data hold by cloud computing providers. One of the penalties of moving data processing and storage off business site is that organizations have fewer controls over their infrastructure. seeing that, cloud service (CS) providers must hope that the CS provider is capable to protect their data and infrastructure from both exterior and domestic attacks. Presently however, such hope can only rely on organizational procedures stated by the CS provider and cannot be remotely verified and validated by an external party. The central distinction between cloud computing and conventional enterprise internal Information Technology services is that the proprietor and the consumer of cloud Information Technology infrastructures are separated in cloud. This transform requires a safety responsibility severance in cloud computing. Cloud service providers (CSP) should safe the services they propose and cannot surpass the customers’ authorities. Virtualization is a buildup utterance in the Information Technology world. With the assure to reduce the ever mounting infrastructure inside data centers connected to other important apprehensions such as ease of use and scalability, virtualization technology has been in advance recognition not only with IT experts yet also among administrators and executives as well. The progressively more growing rate of the approval of this technology has exposed these systems to new protection concerns which in recent history have been unnoticed or merely overlooked. This paper presents an in depth state of art gaze at present most old server virtualization explanations, as well as a writing study on different security matters found inside this virtualization technology. These problems can be practical to all the existing virtualization technologies accessible with no spotlight on a specific answer. Nevertheless, we do susceptibility investigation of two of the mainstream recognized virtualization answers: VMware ESX and Xen. to conclude, we illustrate some clarifications on how to progress the security of online banking and electronic commerce, using virtualization.

AbstractOrganizational networks are vulnerable to trafficanalysis attacks that enable adversaries to infer sensitive information fromnetwork traffic—even if encryption is used. Typical anonymous communication networks are tailored to the Internet and are poorly suited for organizational networks.We present PriFi, an anonymous communication protocol for LANs, which protects users against eavesdroppers and provides high-performance traffic-analysis resistance. PriFi builds onDining Cryptographers networks (DC-nets), but reduces the high communication latency of prior designs via a new client/relay/server architecture, in which a client’s packets remain on their usual network path without additional hops, and in which a set of remote servers assist the anonymization process without adding latency. PriFi also solves the challenge of equivocation attacks, which are not addressed by related work, by encrypting traffic based on communication history. Our evaluation shows that PriFi introduces modest latency overhead (≈ 100ms for 100 clients) and is compatible with delay-sensitive applications such as Voice-over-IP.

Full textAbstract:
Numerous studies have been conducted to develop concurency control schemes that can be applied to client-server systems, such as the Validation Queue (VQ) scheme, which uses object caching on the client side. This scheme has been modified into the Serial Graph-Validation Queue (SG-VQ) scheme, which employs validation algorithms based on queues on the client side and graphs on the server side. This study focuses on verifying the correctness of the SG-VQ scheme by using serializability as a mathematical tool. The results of this study demonstrate that the SG-VQ scheme can execute its operations correctly, in accordance with Theorem 4.16, which states that every history (H) of SG-VQ is serializable. Implementing a cycle-free transaction graph is a necessary and sufficient condition to achieve serializability. To prove Theorem 4.16, mathematical statements involving ten definitions, two propositions, and three lemmas have been formulated.

Full textAbstract:
Aero engine running is complex mechanical experiments. In the last two decades, many computer aided testing (CAT) systems were developed and employed in aero engine running. Traditionally, the main role of a CAT system is data acquisition, which developed with the client/server (C/S) architecture. Now, a CAT system plays more and more important roles in information management, such as measurement channels management, experiment design and management, data analysis and report management, and so on. Users may work on local place or on remote. So, it is not only a data acquisition system, but also an information system. In this paper, we introduce hybrid architecture of C/S and browser/server (B/S) to take advantages of both of them. For local users, clients are realized to provide local monitor and operation. For remote users, browsers provide not only real-time measurement data, but also querying and management of the history data. It demonstrates that the CAT system meets the requirement of aero engine running.

Full textAbstract:
This paper introduces an interactive Memex-like application using a self-modifiable Petri Net model — Self-modifiable Color Petri Net (SCPN). The Memex ("memory extender") device proposed by Vannevar Bush in 1945 focused on the problems of "locating relevant information in the published records and recording how that information is intellectually connected". The important features of Memex include associative indexing and retrieval. In this paper, the self-modifiable functions of SCPN are used to achieve trail recording and retrieval. A place in SCPN represents a website and an arc indicates the trail direction. Each time when a new website is visited, a place corresponding to this website will be added. After a trail is built, users can use it to retrieve the websites they have visited. Besides, useful user interactions are supported by SCPN to achieve Memex functions. The types of user interactions include the following — forward, backward, history, search, etc. A simulator has been built to demonstrate that the SCPN model can realize Memex functions. Petri net instances can be designed to model trail record, back, and forward operations using this simulator. Furthermore, a client-server based application system has been built. Using this system, a user can surf online and record his surfing history on the server according to different topics and share them with other users.

Full textAbstract:
Toxoplasmosis remains a devastating protozoan disease induced by Toxoplasma gondii (T. gondii) that induces extreme hazards in both medical and veterinary fields. Our previous studies revealed the high immunogenicity and antigenicity of T. gondii peroxiredoxin (TgPrx) 1, 3, and TgGRA7. Herein, the comparison of TgPrx1, TgPrx3, and TgGRA7 was conducted using bioinformatics analysis tools. In this computational comparison, the physico-chemical, morphometric, immunogenic, and antigenic properties were analyzed. Analyses of complete coding sequences showed the probability of signal peptides and transmembrane domains only in the case of TgGRA7. NetPhos server-based prediction revealed 23, 11, and 39 phosphorylation sites in TgGRA7, TgPrx1, and TgPrx3 proteins, respectively. The secondary structure of TgGRA7, TgPrx1, and TgPrx3 proteins were analyzed by PSIPRED servers. The percentage of the random coil and alpha-helix amino acids was higher in TgGRA7 (99.15%), followed by TgPrx3 (85.87%) and TgPrx1 (77.55%). The antigenic epitopes of the protein were predicted by analyzing the features of the IEDB server. The linear B-cell epitope regions prediction of TgGRA7 showed the maximum estimated length (118 amino acid residues). In addition, antigenicity and hydrophilicity index showed similar tendencies among the three tested proteins, TgGRA7, TgPrx1, and TgPrx3. Thus, the current computational analyses represented TgGRA7, TgPrx1, and TgPrx3 proteins as efficient diagnostic and vaccine candidates suggesting further research and assessments. Additional validation of bioinformatic analysis tools in predicting potent diagnostic and vaccine antigens will greatly contribute to the success of control policies against T. gondii and other infectious agents.

Full textAbstract:
Collaborative filtering is a popular approach for building an efficient and scalable recommender system. However, it has not unleashed its full potential due to the following problems. (1) Serious privacy concerns: collaborative filtering relies on aggregated user data to make personalized predictions, which means that the centralized server can access and compromise user privacy. (2) Expensive resources required: conventional collaborative filtering techniques require a server with powerful computing capacity and large storage space, so that the server can train and maintain the model. (3) Considering only one form of user feedback: most existing works aim to model user preferences based on explicit feedback (e.g., ratings) or implicit feedback (e.g., purchase history, viewing history) due to their heterogeneous representation; however, these two forms of feedback are abundant in most collaborative filtering applications, can both affect the model, and very few works studied the simultaneous use thereof. To solve the above problems, in this study we focus on implementing decentralized probabilistic matrix factorization for privacy-preserving recommendations. First, we explore the existing collaborative filtering algorithms and propose a probabilistic matrix co-factorization model. By integrating explicit and implicit feedback into a shared probabilistic model, the model can cope with the heterogeneity between these two forms of feedback. Further, we devise a decentralized learning method that allows users to keep their private data on the end devices. A novel decomposing strategy is proposed for users to exchange only non-private information, in which stochastic gradient descent is used for updating the models. Complexity analysis proves that our method is highly efficient with linear computation and communication complexity. Experiments conducted on two real-world datasets FilmTrust and Epinions show that our model gains a guarantee of convergence as the RMSE decreases quickly within 100 rounds of iterations. Compared with the state-of-the-art models, our model achieves lower model loss in rating prediction task and higher precision in item recommendation task.

Full textAbstract:
With an increasing number of web users, the data traffic generated by these users generates tremendous network traffic which takes a long time to connect with the web server. The main reason is, the distance between the client making requests and the servers responding to those requests. The use of the CDN (content delivery network) is one of the strategies for minimizing latency. But, it incurs additional cost. Alternatively, web caching and preloading are the most viable approaches to this issue. It is therefore decided to introduce a novel web caching strategy called optimized popularity-aware modified least frequently used (PMLFU) policy for information retrieval based on users' past access history and their trends analysis. It helps to enhance the proxy-driven web caching system by analyzing user access requests and caching the most popular web pages driven on their preferences. Experimental results show that the proposed systems can significantly reduce the user delay in accessing the web page. The performance of the proposed system is measured using IRCACHE data sets in real time.

This paper addresses the design of a system to facilitate individual environmental risk assessment and long-term risk management in the Industry 4.0 work context. The solution is based on IoT to provide data related to workers’ exposure to hazardous agents (dust, noise, ultraviolet radiation, poor lighting, and inappropriate temperature and humidity) through a simple interface for employees and employers. The system includes a monitoring device and a server and performs employee registration, receives secure messages from the monitoring devices, shows information about the workers’ exposure, and triggers alarms when the measures reach or exceed the limits established by applicable legislation and/or standards. The system was tested in a controlled environment, and the results are presented in this work. Our solution is still under development, and in future stages, it will include a smartphone app for employees to check their exposures and the use of artificial intelligence on the server, which is expected to enable long-term planning by companies based on the analysis of employees’ health history and their exposures to hazardous agents.

In order to effectively process multimedia digital contents in the wireless LAN environment of a smart home, a server higher than the PC level is required. There is also a need for a support system that can exchange multimedia digital contents between clients of home appliances. Therefore, in this paper, we propose a Smart Home Digital Contents Management and Operation System (SDCMOS) that effectively processes and supports multimedia digital contents. This system is designed to effectively process real-time multimedia processing in home service in a wireless LAN environment. In addition, it was made possible to efficiently search multimedia information directly from the home server. SDCMOS is designed to be usable in fields such as biomedical image search, history museums, art exhibition halls, tourism information, geographic information, and e-commerce.
