Singapore’s research has grown significantly since the first national R&D plan was launched in 1991, the same year Nanyang Technological University (NTU) was established. NTU’s research progression, vitally funded by the government, mirrored the substantial growth of Singapore’s research. NTU began as an engineering-based higher education institution that also had a school for accountancy and business, but more schools were added after 2000. Since then, the university has established a research ecosystem that includes research centres of excellence, corporate labs, and medium-sized research centres. Concurrently, the development of research administration in NTU has evolved from providing pre- and post-award support, extending to include outreach, research integrity and ethics, bibliometrics analysis, and talent recruitment and career support. The evolution of administrative needs and capabilities following the changing environment underscores the dynamic nature of research management and administration in Singapore.

This paper aims to adapt and computerize the Trail Making Test (TMT) to support long-term self-assessment of cognitive abilities.

The authors propose a divide-and-combine (DAC) approach for generating different instances of TMT that can be used in repeated assessments with nearly no discernible practice effects. In the DAC approach, partial trails are generated separately in different layers and then combined to form a complete TMT trail.

The proposed approach was implemented in a computerized test application called iTMT. A pilot study was conducted to evaluate iTMT. The results show that the instances of TMT generated by the DAC approach had an adequate level of difficulty. iTMT also achieved a stronger construct validity, higher test–retest reliability and significantly reduced practice effects than existing computerized tests.

The preliminary results suggest that iTMT is suitable for long-term monitoring of cognitive abilities. By supporting self-assessment, iTMT also can help to crowdsource the assessment processes, which need to be administered by healthcare professionals conventionally, to the patients themselves.

Today’s software engineers often work in teams to develop complex software systems. Therefore, successful software engineering in practice require team members to possess not only sound programming skills such as analysis, design, coding and testing but also soft skills such as communication, collaboration and self-management. However, existing examination-based assessments are often inadequate for quantifying students’ soft skill development. The purpose of this paper is to explore alternative ways for assessing software engineering students’ skills through a data-driven approach.

In this paper, the exploratory data analysis approach is adopted. Leveraging the proposed online agile project management tool – Human-centred Agile Software Engineering (HASE), a study was conducted involving 21 Scrum teams consisting of over 100 undergraduate software engineering students in multi-week coursework projects in 2014.

During this study, students performed close to 170,000 software engineering activities logged by HASE. By analysing the collected activity trajectory data set, the authors demonstrate the potential for this new research direction to enable software engineering educators to have a quantifiable way of understanding their students’ skill development, and take a proactive approach in helping them improve their programming and soft skills.

To the best of the authors’ knowledge, there has yet to be published previous studies using software engineering activity data to assess software engineers’ skills.

With the rapid growth of the Internet of Things (IoT) market and requirement, low power wide area (LPWA) technologies have become popular. In various LPWA technologies, Narrow Band IoT (NB-IoT) and long range (LoRa) are two main leading competitive technologies. Compared with NB-IoT networks, which are mainly built and managed by mobile network operators, LoRa wide area networks (LoRaWAN) are mainly operated by private companies or organizations, which suggests two issues: trust of the private network operators and lack of network coverage. This study aims to propose a conceptual architecture design of a blockchain built-in solution for LoRaWAN network servers to solve these two issues for LoRaWAN IoT solution.

The study proposed modeling, model analysis and architecture design.

The proposed solution uses the blockchain technology to build an open, trusted, decentralized and tamper-proof system, which provides the indisputable mechanism to verify that the data of a transaction has existed at a specific time in the network.

To the best of our knowledge, this is the first work that integrates blockchain technology and LoRaWAN IoT technology.

Planning and control of humanoid biped walking has been an active research topic for many years. But, there is no definite answer to the question of how to practicre‐examinedally achieve speedy and stable walking in real‐time and in a changing environment. The purpose of this paper is to re‐examine the issue of planning and controlling humanoid biped walking, then to propose two new ideas.

The first idea is to treat the supporting foot of a biped to be part of the ground. In this way, there is a foot reaction force acting at a fixed virtual joint, which can be at, or below, the ankle joint. And, a new concept is come our that is named as in‐foot ZMP in contrast to the existing concept of on‐ground ZMP. The unique benefit with this new concept of in‐foot ZMP is that the ZMP control is no longer an issue because the in‐foot ZMP can be controlled so as to to be at a fixed virtual joint during a stable walking. Such a fixed virtual joint can be called a ZMP joint.

The second idea is to focus on hip's trajectory (instead of on‐ground ZMP's trajectory) and to split a hip's dynamic response into two independent parts: one is the steady‐state response contributing to the stability of walking (or standing), and the other is the transient response contributing to the speed of walking. This idea allows us to explicitly postulate the necessary and sufficient condition for achieving leg stability as well as the necessary and sufficient condition for achieving foot stability. The paper shows that the implementation of these two new ideas help realize a unified framework for task‐guided, intention‐guided, and sensor‐guided, planning and control of humanoid biped walking.

This paper first re‐examines the issue of planning and controlling humanoid biped walking, then proposes two new ideas. The first idea is to treat the supporting foot of a biped to be part of the ground. The second idea is to focus on hip's trajectory (instead of on‐ground ZMP's trajectory) and to split a hip's dynamic response into two independent parts: one is the steady‐state response contributing to the stability of walking (or standing), and the other is the transient response contributing to the speed of walking.

This study aimed to acquire knowledge about Singapore secondary school (ages 13 to 16 years old) students' skills in searching, evaluating and using information.

A comprehensive instrument encompassing the basic information literacy (IL) skills, as well as a new dimension of ethical usage of information and collaborative information seeking was used for data collection. From August to November 2010, a total of eight schools comprising 3,164 students participated in this study.

It was a matter of concern that various kinds of libraries, including school libraries, were found to be under-utilized. From the test that was administered to assess the IL skills of students, the results were found to be generally unsatisfactory as each of the major categories of IL skills recorded a score that is below 50 (out of a maximum of 100) except for “task definition”. For skills related to “information seeking strategies”, “location & access” and “information use”, the types of schools, academic streams of study, and students' family background seemed to have significant influences.

This study is the first large-scale survey conducted in Singapore that sought to test the IL skills of secondary school students. The findings are useful in assessing the current effectiveness of IL integration, and the need for a more planned approach towards IL competency training within the school curriculum in Singapore.

Poor medication adherence leads to high hospital admission rate and heavy amount of health-care cost. To cope with this problem, various electronic pillboxes have been proposed to improve the medication adherence rate. However, most of the existing electronic pillboxes use time-based reminders which may often lead to ineffective reminding if the reminders are triggered at inopportune moments, e.g. user is sleeping or eating.

In this paper, the authors propose an AI-empowered context-aware smart pillbox system. The pillbox system collects real-time sensor data from a smart home environment and analyzes the user’s contextual information through a computational abstract argumentation-based activity classifier.

Based on user’s different contextual states, the smart pillbox will generate reminders at appropriate time and on appropriate devices.

This paper presents a novel context-aware smart pillbox system that uses argumentation-based activity recognition and reminder generation.

Many open source software packages are available for organizations and individuals to create digital libraries (DLs). However, a simple to use instrument to evaluate these DL software packages does not exist. The objectives of the present work are to develop a checklist for DL evaluation and use this checklist on four DL software packages.

Features that characterized “good” open source DL software were determined from the literature. First identified were essential categories of features that DL software should possess. These categories were then decomposed into supporting features. From these, a checklist that covered all such features was developed. The checklist was then used to evaluate four popular open source DL software packages (CDSware, EPrints, Fedora, and Greenstone) for the purposes of assessing suitability for use in a DL project to be undertaken by the authors.

A checklist consisting of 12 categories of items was developed. Using this, Greenstone was found to be the best performer, followed by CDSware, Fedora and EPrints. Greenstone was the only software package that consistently fulfilled the majority of the criteria in many of the checklist categories. In contrast, EPrints was the worst performer due to its poor support for certain features deemed important in our checklist, and a total absence of functionality in other categories.

The present work attempts to develop a comprehensive checklist for assessing DLs. Its flexibility allows users to tailor it to accommodate new categories, items and weighting schemes to reflect the needs of different DL implementations.

This study investigates the information needs and information seeking behaviour of computer engineering undergraduate students at Nanyang Technological University (NTU), Singapore. The purpose was to investigate the types of information sources used by the students, their preferred information formats, the importance of and reasons for using certain information sources and the use of various electronic information sources. A questionnaire was distributed to 200 randomly selected students and 102 completed questionnaires were returned. The study found that printed materials were the most preferred information format among the students. The top five most preferred information sources, in the order of importance, were books, lecturers, the Internet, friends and manuals. Unexpectedly, the use of databases and electronic journals was quite low among the computer engineering students. The study recommends a promotional campaign for introducing electronic information sources to the library users.

This paper presents the results of a heuristic‐based user interface evaluation of the gateway to electronic media services (GEMS) system at Nanyang Technological University (NTU) in Singapore. GEMS provides access to multimedia resources, bibliographic information, electronic document management, selective dissemination of information (SDI), booking of facilities, and several other services. Results of an evaluation of GEMS, based on Nielsen’s ten‐user interface heuristics involving 88 students, are described. Details of a separate task‐based study, involving 52 other participants, of the University’s OPAC interface are also given as a means to compare GEMS with the OPAC in terms of usability, task performance and other factors.
