The Future of Digital Healthcare in Cardiac Prevention Programme in Indonesia: From Bedside to Boardroom

Digital technology has become integral to the practice of medicine, especially in response to the COVID-19 pandemic and its associated lockdowns and social distancing measures. It has allowed patients, including those undergoing cardiac rehabilitation, to access healthcare services regardless of their geographical location. However, the widespread integration of digital healthcare on a national scale presents numerous challenges. These obstacles encompass various aspects, including patient–physician relationships, legal policies, health information system quality, data privacy, cost–benefit analysis and the potential loss of essential human interaction. To address these hurdles, Indonesia has developed a framework and strategy for implementing digital healthcare. This review examines the experiences of digital healthcare leaders in different countries, considering their unique healthcare systems, cultural contexts and approaches to tackling these issues. Additionally, an analysis of Indonesia’s current healthcare system implementation is provided. By showcasing successful examples and considering critical factors, we hope to facilitate a successful implementation of digital healthcare in cardiac prevention while gathering valuable insights from these endeavours.

On Leveraging FemtoClouds for Federated Learning

The massive amount of data generated by mobile/IoT devices worldwide has been both a motivation and a key enabler for Machine Learning (ML)-based applications. Cloud and Edge platforms have been traditionally leveraged as underlying systems where data for ML applications is processed using “Centralized ML.” Federated Learning (FL) was introduced as an alternative solution that provides comparable accuracy, to centralized-ML, while maintaining user privacy. FL allows training data on its source device and only model updates can leave the device for learning aggregation at the Cloud/Edge. However, current FL solutions have limitations that originate from the training process and current system implementations. Hence, in this paper, we propose leveraging FemtoClouds (i.e. ensembles of co-located mobile/IoT devices) as a complementary system to existing FL approaches. We discuss and assess the benefits that FemtoClouds introduce for both the FL training algorithms, and end devices. These benefits include improvements in training accuracy, convergence speed, training time, and energy efficiency. We finally discuss challenges and future research directions that need to be addressed to realize the benefits of Femto Clouds-based FL.

Subcarrier wave continuous variable quantum key distribution with discrete modulation: mathematical model and finite-key analysis

In this paper we report a continuous-variable quantum key distribution protocol using multimode coherent states generated on subcarrier frequencies of the optical spectrum. We propose a coherent detection scheme where power from a carrier wave is used as a local oscillator. We compose a mathematical model of the proposed scheme and perform its security analysis in the finite-size regime using fully quantum asymptotic equipartition property technique. We calculate a lower bound on the secret key rate for the system under the assumption that the quantum channel noise is negligible compared to detector dark counts, and an eavesdropper is restricted to collective attacks. Our calculation shows that the current realistic system implementation would allow distributing secret keys over channels with losses up to 9 dB.

Using hybrid algorithmic-crowdsourcing methods for academic knowledge acquisition

Scientific literature contains a lot of meaningful objects such as Figures, Tables, Definitions, Algorithms, etc., which are called Knowledge Cells hereafter. An advanced academic search engine which could take advantage of Knowledge Cells and their various relationships to obtain more accurate search results is expected. Further, it’s expected to provide a fine-grained search regarding to Knowledge Cells for deep-level information discovery and exploration. Therefore, it is important to identify and extract the Knowledge Cells and their various relationships which are often intrinsic and implicit in articles. With the exponential growth of scientific publications, discovery and acquisition of such useful academic knowledge impose some practical challenges For example, existing algorithmic methods can hardly extend to handle diverse layouts of journals, nor to scale up to process massive documents. As crowdsourcing has become a powerful paradigm for large scale problem-solving especially for tasks that are difficult for computers but easy for human, we consider the problem of academic knowledge discovery and acquisition as a crowd-sourced database problem and show a hybrid framework to integrate the accuracy of crowdsourcing workers and the speed of automatic algorithms. In this paper, we introduce our current system implementation, a platform for academic knowledge discovery and acquisition (PANDA), as well as some interesting observations and promising future directions.

Semiautomated Verification of Access Control Implementation in Industrial Networked Systems

Access control is a necessary building block in the security of any kind of cyber system and, in this sense, industrial networked systems (INSs) make no exception. Typically, access control policies are specified at a high implementation-independent level of abstraction and then mapped onto the real system by leveraging available policy enforcement mechanisms. Unfortunately, different from general-purpose ICT systems, enforcement mechanisms are generally very basic in INS. As a consequence, verifying the correctness of policy implementation becomes a crucial task, especially cumbersome when it needs to be carried out entirely by hand. This paper presents a new methodology, which also serves as the basis of a purposely developed software tool conceived to cope with the lack of policy enforcement mechanisms in INS and to allow semiautomatic verification of policy implementation. Our approach is based on a twofold system model that enables both the abstract specification of access control policies and the detailed description of the target physical system. These two separate views are then combined to automatically determine whether the current system implementation matches the policy specification.

KINGDOM OF SAUDI ARABIA GEOSPATIAL INFORMATION INFRASTRUCTURE – AN INITIAL STUDY

Abstract. This paper reviews the current Geographic Information System (Longley et al.) implementation and status in the Kingdom of Saudi Arabia (KSA). Based on the review, several problems were identified and discussed. The characteristic of these problems show that the country needs a national geospatial centre. As a new initiative for a national geospatial centre, a study is being conducted especially on best practice from other countries, availability of national committee for standards and policies on data sharing, and the best proposed organization structure inside the administration for the KSA. The study also covers the degree of readiness and awareness among the main GIS stakeholders within the country as well as private parties. At the end of this paper, strategic steps for the national geospatial management centre were proposed as the initial output of the study.

SND data acquisition system upgrade

The data acquisition (DAQ) system of the SND detector successfully operated during four data-taking seasons (2010–2013) at the e+e− collider VEPP-2000. Currently the collider is shut down for planned reconstruction, which is expected to increase the VEPP-2000 luminosity and data flow from the SND detector electronics by up to 10 times.Since current DAQ system implementation (electronics and computer part) does not have enough reserve for selection of events in the new environment without compromising quality, there arose the need for the system upgrade.Here we report on the major SND data acquisition system upgrade which includes developing new electronics for digitization and data transfer, complete redesign of the data network, increasing of the DAQ computer farm processing capacity and making the event building process concurrent. These measures will allow us to collect data flow from the most congested detector subsystems in parallel in contrast to the current situation. We would like to discuss also the possibility to implement full software trigger solution in the future.

The Encyclopedia of Life v2: Providing Global Access to Knowledge About Life on Earth.

The Encyclopedia of Life (EOL, http://eol.org) aims to provide unprecedented global access to a broad range of information about life on Earth. It currently contains 3.5 million distinct pages for taxa and provides content for 1.3 million of those pages. The content is primarily contributed by EOL content partners (providers) that have a more limited geographic, taxonomic or topical scope. EOL aggregates these data and automatically integrates them based on associated scientific names and other classification information. EOL also provides interfaces for curation and direct content addition. All materials in EOL are either in the public domain or licensed under a Creative Commons license. In addition to the web interface, EOL is also accessible through an Application Programming Interface.In this paper, we review recent developments added for Version 2 of the web site and subsequent releases through Version 2.2, which have made EOL more engaging, personal, accessible and internationalizable. We outline the core features and technical architecture of the system. We summarize milestones achieved so far by EOL to present results of the current system implementation and establish benchmarks upon which to judge future improvements.We have shown that it is possible to successfully integrate large amounts of descriptive biodiversity data from diverse sources into a robust, standards-based, dynamic, and scalable infrastructure. Increasing global participation and the emergence of EOL-powered applications demonstrate that EOL is becoming a significant resource for anyone interested in biological diversity.

System-Level Performance and Characterization of Counter-Phase Optical Interference Cancellation

In this paper, we report on the performance of the second implementation of the optical counter-phase RF interference cancellation technique. Referred to as the opto-cancellation system, it has demonstrated narrowband-signal cancellation exceeding 80 dB. Also, broadband signals of 80-MHz bandwidth, whose center frequencies ranged from 1 GHz-20 GHz, were cancelled down to the system noise floor; where that cancellation was approximately uniform over the full bandwidth of each signal. It is not known that other interference cancellation systems can achieve such low cancellation depths, over such a wide frequency bandwidth, at the time of this writing. In addition to describing the system's performance in terms of experimental results, we also characterize the system's performance analytically. Although the sensitivity, gain, linearity, and noise figure of the current system implementation are known, the analysis presented here will be useful for future implementations of the optical counter-phase RF interference cancellation technique. The analysis will also aid in understanding the trade-offs and limitations of the current system implementation, as well as future implementations.

Towards computer-vision software tools to increase production and accessibility of video description for people with vision loss

This paper presents the status of a R&D project targeting the development of computer-vision tools to assist humans in generating and rendering video description for people with vision loss. Three principal issues are discussed: (1) production practices, (2) needs of people with vision loss, and (3) current system design, core technologies and implementation. The paper provides the main conclusions of consultations with producers of video description regarding their practices and with end-users regarding their needs, as well as an analysis of described productions that lead to propose a video description typology. The current status of a prototype software is also presented (audio-vision manager) that uses many computer-vision technologies (shot transition detection, key-frame identification, key-face recognition, key-text spotting, visual motion, gait/gesture characterization, key-place identification, key-object spotting and image categorization) to automatically extract visual content, associate textual descriptions and add them to the audio track with a synthetic voice. A proof of concept is also briefly described for a first adaptive video description player which allows end users to select various levels of video description.

Canadian government agencies develop e-mail management policies

As e-mail has become a widely used communication tool by the Government of Canada (GoC), this article examines current e-mail management policies and system implementation in Canadian government agencies. GoC implemented the Records, Document, and Information Management System (RDIMS) as an integrated system tool for efficient document and records management. RDIMS provides the capability to create, manage, and access information and documents, regardless of ministerial, departmental, or geographic location. GoC presents legal guidance on e-mail management, based on the Access to Information Act, Privacy Act, and Library and Archives of Canada Act. Developing an e-mail management policy promotes an effective capture, management, and retention of e-mail messages.

On the Scalability of Description Logic Instance Retrieval

Practical description logic systems play an ever-growing role for knowledge representation and reasoning research even in distributed environments. In particular, the ontology layer of the often-discussed semantic web is based on description logics (DLs) and defines important challenges for current system implementations. The article introduces and evaluates optimization techniques for the instance retrieval problem w.r.t. the description logic $\mathcal{SHIQ}(\mathcal{D}_{n})^{-}$ , which covers large parts of the Web Ontology Language (OWL). We demonstrate that sound and complete query engines for OWL-DL can be built for practically significant query classes. Experience with ontologies derived from database content has shown that it is often necessary to effectively solve instance retrieval problems with respect to huge amounts of data descriptions that make up major parts of ontologies. We present and analyze the main results about how to address this kind of scalability problem.

ACAS II and ATC—A Competition on Surveillance Performance?

After many years of extensive analysis, development and flight evaluation, a solution is available to the problem of reducing the risk of mid-air collisions between aircraft. This solution is known as the Airborne Collision Avoidance System (ACAS II), standardised by the International Civil Aviation Organisation ICAO. As of now there is only one implementation available which is TCAS II, the Traffic Alert and Collision Avoidance System. While there was a broad consensus that ACAS II operation should not cause harmful radio frequency interference to the existing air traffic control (ATC) system, a long and controversial discussion took place on how to achieve this goal. It turned out that there has to be a compromise, not only to ensure sufficient surveillance performance for the ground based ATC system but also for other systems, like ACAS, using the same frequency channels. Extensive validation effort has been conducted with flight trials as well as simulations in US, UK, and Germany. This paper describes the radio frequency interaction between airborne and ground based surveillance systems, gives some background information and rationale for the current system implementations, and introduces some ideas on possible future improvements, which might be necessary due to future traffic densities, new operational procedures, and the move towards future air traffic management improvements.

PLAYBOT A visually-guided robot for physically disabled children

This paper overviews the PLAYBOT project, a long-term, large-scale research program whose goal is to provide a directable robot which may enable physically disabled children to access and manipulate toys. This domain is the first test domain, but there is nothing inherent in the design of PLAYBOT that prohibits its extension to other tasks. The research is guided by several important goals: vision is the primary sensor; vision is task directed; the robot must be able to visually search its environment; object and event recognition are basic capabilities; environments must be natural and dynamic; users and environments are assumed to be unpredictable; task direction and reactivity must be smoothly integrated; and safety is of high importance. The emphasis of the research has been on vision for the robot this is the most challenging research aspect and the major bottleneck to the development of intelligent robots. Since the control framework is behavior-based, the visual capabilities of PLAYBOT are described in terms of visual behaviors. Many of the components of PLAYBOT are briefly described and several examples of implemented sub-systems are shown. The paper concludes with a description of the current overall system implementation, and a complete example of PLAYBOT performing a simple task.

On the reappointment of cognitive responsibility in user-system dialogues

As the number of information system users increase, we are witnessing a related increase in the complexity and diversity of their applications. This complexity amplifies the degree of functional and technical understanding required of the user to productively use the application tools. Aspects related to this increased understanding include human memory requirements, system command interpretation and command formulation, and problem solving strategies. In most current system implementations the responsibility for obtaining an active understanding of the system and ensuring a correct and effective user-system dialogue resides with the user. This research will explore the feasibility of, and the necessary conditions for dynamic reapportionment of cognitive tasks in the human-system dialogue.

An object-oriented approach to database system implementation

This paper examines object-oriented programming as an implementation technique for database systems. The object-oriented approach encapsulates the representations of database entities and relationships with the procedures that manipulate them. To achieve this, we first define abstractions of the modeling constructs of the data model that describe their common properties and behavior. Then we represent the entity types and relationship types in the conceptual schema and the internal schema by objects that are instances of these abstractions. The generic procedures (data manipulation routines) that comprise the user interface can now be implemented as calls to the procedures associated with these objects. A generic procedure model of database implementation techniques is presented and discussed. Several current database system implementation techniques are illustrated as examples of this model, followed by a critical analysis of our implementation technique based on the use of objects. We demonstrate that the object-oriented approach has advantages of data independence, run-time efficiency due to eliminating access to system descriptors, and support for low-level views.

The Data Acquisition System for the Neutron Scattering Instruments at the Intense Pulsed Neutron Source

The Intense Pulsed Neutron Source (IPNS) at Argonne National Laboratory is a major new useroriented facility which is now coming on line for basic research in neutron scattering and neutron radiation damage. This paper describes the data acquisition system which will handle data acquisition and instrument control for the time-of-flight neutron scattering instruments at IPNS. This discussion covers the scientific and operational requirements for this system, and the system architecture that was chosen to satisfy these requirements. It also provides an overview of the current system implementation including brief descriptions of the hardware and software which have been developed.

A software design and evaluation system

A critical failure of current software system design and implementation methodology is that the performance of a proposed design is not evaluated before it is actually implemented. In this paper the reasons for this failure are explored, and a new methodology which overcomes many of the difficulties is proposed. A system which integrates performance evaluation with design and implementation is described. This system is based on a simple, high level language which is used to describe the evolving system at all stages of its development. The source language description is used as direct input to performance analysis and simulation routines. Using the performance information obtained from these routines as feedback, the problems which adversely affect performance are detected early enough so that they can be corrected without costly major reimplementation of the proposed system.
