Innovation diffusion of wearable mobile computing: Pervasive computing perspective
Wearable technology has become mainstream in this information age, it is needed to understand how the potential users of this emerging technology gain value from the innovation of the technology, consequently increasing users’ diffusion. Extant literature on the acceptance of mobile computing has been developing such as in mobile banking services and in healthcare service, however, the study of users’ acceptance about the emergence of wearable mobile computing is still at the early stages. This paper examines the development of a conceptual framework to understand the technology adoption factors for wearable mobile computing utilizing the Technology Acceptance Model (TAM), the Diffusion of Innovation Theory (DOI) and related factors on mobility and pervasive computing. Data of 272 respondents were collected using quantitative approach of survey based questionnaires conducted in Malaysia. The findings of this research revealed the factors of mobility (MOB), personalization (PN) and perceived enjoyment (PE) achieved the highest average score by respondents, followed by perceived usefulness (PU) and perceived ease of use (PEU), observability (OBS), facilitating condition (FC) and social influence (SI). As wearable technology is perceived to be pervasive, mobility (MOB) and perceived enjoyment (PE) contribute the dominant factor for usage acceptance, while Perceived Usefulness (PU) from established model TAM, still plays an important factors in predicting innovation adoption of wearable mobile computing
A framework for collaborative innovation to facilitate E-health systems adoption
The promise of telemedicine is great as observed in developed countries. However, its adoption in developing countries has been very slow. Extant literature on healthcare technological innovation indicates that organization collaboration can expedite the adoption of telemedicine especially in developing countries. The Kenyan government approved telemedicine (use of ICT to overcome geographical barriers and increase access to health care services) as a strategic approach of improving healthcare delivery especially in the marginalized areas of the country. However, the adoption of telemedicine is further hindered in developing countries by the fact that the cost of implementing telemedicine technology is deemed to be high and the resources needed are scarce especially in the public sector. This study employed a conceptual research framework to examine organizational factors that may influence organization collaboration in facilitating telemedicine adoption in developing countries. A questionnaire survey was conducted in 50 hospitals located in Eastern Kenya. The findings of this research revealed that Kenyan hospitals may enhance their ability to adopt telemedicine by affiliating with other organizations. Organization affiliation was found to significantly influence organizational resources, organization innovation acceptance, organization innovation capacity, organization agility and collaborative innovation aspects
Transformasi Identitas Gerakan dari “Petani” Menjadi “Masyarakat Adat”: Upaya Memahami Konflik Pembangunan Bandara Sultan Babullah di Ternate Maluku Utara”
Land conflict in Ternate have been in existence from the era of pre-independence to the present reform era. One example is the conflict over the development of Sultan Babullah Ternate Airport, which has victimized the peasant communities in the village of Tafure. This srudy used a strategy of qualitative method of research. It is intended to development of Sultan Babullah Ternate Airport, examine the formation and development of new social movements in Ternate and its relation to the issues of environmental and socio-economic impacts as well as the issues of ulayat (custom) land and the rights of custom communities, and determine to what extent the peasants' movements could become a solution to win the peasants' rights and at the same tme feasible as the forum to struggle for better life of peasants. This study found that the peasant communities initially launched protests to get the financial compensation for the land used for the airport and then in the next development they changed their movement identity from peasants to custom communities. It was also found that there were some factors that triggered the birth of the new social movement, for example lost farm land, lost housing land, disappearing acces to forest area, lost rights for custom land, lost houses or settlement, lost sources of livelihood or incomes, lost plantation land and cemetery, etc. The emergence of the peasants' social movement in Ternate is motivated by equal feeling of poor life and strong desire for a change However, the management of organizational aspects have not yet fully run well such as filing, financing, and work division. In its development, the peasant's movement has experienced some structural constraints, for example the weak position of peasants concerning the evidence of land ownership, while the cultural obstacle is the presence of internal conflicts or divisions in the movement
Application of Electrical Resistivity Tomography (ERT) and Arial Photographs Techniques in Geo Hazard Assessment of Karst Features in Constructing Sites in Perak, Peninsular Malaysia
This paper illustrates the application of geophysical survey, aerial photographs and satellite images as identification techniques for geohazard assessment of karst features in housing complexes construction sites north of Ipoh city, Perak state, Peninsular Malaysia. The engineers in Perak face numerous problems while designing structures that would be situated over marbleized limestone (carbonate) karst terrains, due to its categorization to various bedrock solution features such as sinkholes, caves, cavities, depressions, conduits enlarged joints and fractures, and internal drainages, which directly exerts a negative impact on the use of this land for construction projects and structures. Furthermore, it can also indirectly have the potential to cause catastrophic damages in the near future perhaps many years after the project has ended. The subsidence damages which result in construction works will cause massive losses which maximize the project overall cost leading to enormous financial costs, to the developers and the lands. In this study, Two-dimensional (2D) electrical resistivity tomography (ERT) survey was performed across three housing complex construction sites north of Ipoh in order to image the subsurface and locate evidence for near surface karstic features such as voids or cavities, including sinkholes and to estimate the depth of the bedrock. It is also done in order to estimate whether geophysical techniques are capable of identifying such features. Six resistivity traverses or profiles were conducted along the survey area at each of the three construction sites. The orientation, extension and the degree of inclination of those profiles are shown in Google’s satellite map. The interpretation of the geophysical data indicated that both low resistivity and high conductivity anomalies extends along the proposed area in all of the construction sites. The ambiguous anomalies observed in construction site # 1 indicated that the area has been exaggerated by a sinkhole, thus it contains non-stiff clay and is saturated with water, rendering it less resistant to electrical currents (high conductivity). The ambiguous anomalies observed in construction site #2 indicated that the area has been affected by several sinkholes and tubular anomalies containing both stiff and sandy clay. The anomaly observed in construction site #3 indicated that the area has been affected by several soil cover collapse sinkholes and tubular anomalies containing stiff, non-stiff and sandy clays. This study also demonstrated that high-resolution Electrical Resistivity Tomography (ERT) can be effectively applied to reflect and differentiate surficial soil, clay, weathered rocks, compact or intact rocks, and air-filled karstic voids or cavities. The appearance of many sinkholes in the area is mostly attributed to karstic activity. In accordance to the classification of the characteristics of morphological features of karstic ground conditions by (A. C. Waltham and P. G. Fookes, 2005), the karst in construction site site#1 found between profile 1 and profile 6 is an older or complex karst type KIV, while the karst in construction site#2 found between profile 1 and profile 3 is a youthful karst type KII. Afterwards, the karst type changed over profile#5 to profile #6 to mature into karst type KIII. The karst in construction site#3, found between profile 1 and profile 3, is a youthful karst type KII. Then, the karsts change in profile 4 to an older, mature karst type KIII. The karsts found between profile #5 and profile#6 is of the older or complex karst type KIV. Early planning is needed to mitigate or minimize the risk of structures in these construction sites over karstified carbonate bedrock. Initial consolidation of geo grids, driven piles to rock head pinnacles, and control drainage works must be put into operation in these respective sites.

Do I trust my machine teammate? An investigation from perception to decision
© 2019 Copyright held by the owner/author(s). In the human-machine collaboration context, understanding the reason behind each human decision is critical for interpreting the performance of the human-machine team. Via an experimental study of a system with varied levels of accuracy, we describe how human trust interplays with system performance, human perception and decisions. It is revealed that humans are able to perceive the performance of automatic systems and themselves, and adjust their trust levels according to the accuracy of systems. The 70% system accuracy suggests to be a threshold between increasing and decreasing human trust and system usage. We have also shown that trust can be derived from a series of users' decisions rather than from a single one, and relates to the perceptions of users. A general framework depicting how trust and perception affect human decision making is proposed, which can be used as future guidelines for human-machine collaboration design
Effect of maleated compatibiliser (PBS-g-MA) addition on the flexural properties and water absorption of poly(butylene succinate)/kenaf bast fibre composites
Poly(butylene succinate) (PBS) composites with 30 wt.% loading of kenaf bast fibre (KBF) were compatibilised with 5 wt.% maleated PBS (PBS-g-MA). The maleic anhydride (MA) concentration in the compatibiliser was either 3, 5, 7 or 10 phr. In general, the compatibilised composites showed better flexural properties than the un-compatibilised composite. The highest increment in the flexural strength and modulus of 12.7 and 8.9%, respectively, were obtained with the addition of PBS-g-MA with MA concentration of 5 phr. Compatibilised and un-compatibilised PBS/KBF composites were immersed in distilled water for 90 days. The absorption of water by all the composites was observed to follow Fick’s law. The equilibrium moisture content, Mm, of the composites with PBS-g-MA at 3, 5 and 7 phr of MA concentrations was lower than that of the un-compatibilised composite due to improved fiber-matrix interfacial adhesion and reduction of voids content. Both un-compatibilised and compatibilised composites showed dimensional instability after the water absorption. This was probably due to the degradation of the fibre-matrix interfacial adhesion and fibre integrity. The flexural properties of these composites decreased after the water absorption. After re-drying only some of the flexural properties were recovered from plasticizing effect of water
Intelligence quotient and perceptual ability: an inter-relationship based on brainwave power ratio features
Cognitive ability refers to the characteristic approach by the brain in processing information. These can be observed through various aspects of cognition such as intelligence and perceptual ability. Studies have shown that both mental constituents originate from the same neurological substrate in the prefrontal cortex. Hence, the paper discusses the relationship between intelligence and perceptual ability using electroencephalogram (EEG) features. The study is based on resting brainwave of fifty samples and focused on the left and right prefrontal cortex. The intelligence quotient (IQ) scores obtained are then used to establish the control groups. Subsequently, the pattern of alpha and theta power ratio for each IQ level is observed and successfully correlated with perceptual ability through the Neural Efficiency Hypothesis of intelligence.Keywords: EEG; intelligence; IQ; perceptual ability; power ratio

Brainwave Classification for Brain Balancing Index (BBI) via 3D EEG Model Using k-NN Technique
In this paper, the comparison between k-Nearest Neighbor (kNN) algorithms for classifying the 3D EEG model in brain balancing is presented. The EEG signal recording was conducted on 51 healthy subjects. Development of 3D EEG models involves pre-processing of raw EEG signals and construction of spectrogram images. Then, maximum PSD values were extracted as features from the model. There are three indexes for the balanced brain; index 3, index 4 and index 5. There are significant different of the EEG signals due to the brain balancing index (BBI). Alpha-α (8–13 Hz) and beta-β (13–30 Hz) were used as input signals for the classification model. The k-NN classification result is 88.46% accuracy. These results proved that k-NN can be used in order to predict the brain balancing application
A vertical wind turbine monitoring system using commercial online digital dashboard
The output of a green energy generator is required to be monitor continuously. The monitoring process is important because the performance of the energy gen- erator needs to be known and evaluate. However, monitoring the generator manu- ally and efficiently is troublesome. Moreover, when most of the energy generator located at uneasy to reach or at a very remote place. Added to the cost, human intervention for the monitoring process contributes to the unnecessary bill. All the highlighted limitations can be overcome using an internet cloud base system and application. Most of the existing data logging instruments use a memory card or personal computer in their operation. The stored data is accessible only at a dedicated computer alone. This work presented a complete energy generator interface with a commercial online digital dashboard. The digital dashboard, parameters of the wind turbine, such as the amount of power generates and the magnitude of instantaneous voltage can be monitored, and the recorded data can be accessed quickly, at any time and anyplace
