Augmented Reality (AR) applications running on mobile devices have become more popular in recent years. As with digital games, many developers have begun to direct their applications to mobile platforms, although the processing power of these devices is usually smaller when compared to the computing power of laptops and desktops. Applications developed for computing devices, including mobile devices,...
In this work, we propose an efficient architecture for the hardware realization of deep neural networks on reconfigurable computing platforms like FPGA. The proposed neural network architecture employs only one single physical computing layer to perform the whole computational fabric of fully-connected feedforward deep neural networks with customizable number of layers, number of neurons per layer...
Paralleling source code is the most common approach to optimize the performance of Android applications on multi-core processors. However, the problem of selecting a good parallel structure and its parameter tube is still a challenge. This paper proposes the performance optimization method based on selecting the best parallel configuration including the parallel structure and corresponding parameter...
Educational use of mobile robots is among the most explored subtopics of Human-Robot Interaction (HRI), given the potential attention calling possibilities drawn by its novelty aspect. In educational environments is expected that social robots enhance learning, such as virtual agents that have been used. However, the real effect of applying a physical robot has not been well exploited. This paper...
Noticeable performance degradation of IEEE 802.15.4-based wireless body sensor networks (WBSNs) caused by the mutual interference has recently drawn the attention of research communities. Frequency-adaptation is to some extent an effective solution to reduce the impact of mutual interference on WBSN's performance. However, as the number of WBSNs becomes larger, this scheme is destined to fail. In...
Quadrotor unmanned aerial vehicles (UAVs) have seen a surge of use in various applications due to its structural simplicity and high maneuverability. However, conventional control methods using joysticks prohibit novices from getting used to maneuvering quadrotors in short time. In this paper, we suggest the use of a wearable device, such as a smart watch, as a new remote-controller for a quadrotor...
The number of mobile users have grown tremendously in the past few years. Nowadays, mobile phones are not just used for the purpose of making calls, rather they have become an important modern gadget which helps people in various aspects of their lives. With this increase, a lot of time on mobile is spent in browsing the internet websites through mobile web browsers. Hence, mobile web browsers actually...
Lung disease has been reported by World Health Organization (WHO) to have caused 2.77% of total death in Malaysia and is the 6th main cause of death which includes interstitial lung disease (ILD). ILD causes alteration and fibrosis in the lungs leading to breathing complications and can be diagnosed and analyzed using high resolution computed tomography (HRCT). Previous study has developed a robust...
With the advent of smart devices and lowering prices of sensing devices, adoption of Internet of Things (IoT) is gaining momentum. These IoT devices come with greater threat of being attacked or compromised that could lead to Denial of Service (DoS) and Distributed Denial of Service (DDoS). The high volume of IoT devices with high level of heterogeneity, magnify the possibility of security threats...
The design space exploration of Networks-on-Chip (NoC) requires tools to evaluate the network performance, tune its parameters and achieve the requirements of the target application. In this context, this paper presents RedScarf, a simulation environment with graphical user interface and a set of tools that automate the design space exploration of NoCs. It presents many resources that make RedScarf...
Virtual Reality may be considered a computational tool often used to aid in medical training, specially in surgical training. That allows surgeons to gain dexterity and experience in surgery without risking real patient lifes, reducing the probability of medical errors to occur, henceforth providing a better quality of life to patients. Due to the fragility of the human eye, more than most other areas...
Mobile applications are usually developed in a native way, using languages and APIs specific for a given platform, hindering the portability. As an alternative, web technologies as JavaScript and PHP have been employed enabling a same implementation to be executed in different mobile platforms without any recompilation or recoding process. This paper compares the efficiency of Android applications...
This paper presents a free hand interface for modeling virtual terrains in an augmented reality environment. A secondary contribution of this work is to present a study of a set of suitable gestures that allows the manipulation of virtual terrains interactively, using augmented reality markers and the Leap Motion Controller. To demonstrate the study, an application was developed to allow the user...
It is fact that technology has positively influenced educational field, like the education based on digital games. Besides that, one of the technologies that has gained recent notoriety is Virtual Reality, that can provide disruptive approaches of interaction on games. Even that the approach to learn using digital games is very motivating, it is not known the effectiveness of this method using immersive...
Gene Expression Networks (GENs) attempt to model how genetic information stored in the DNA (Genotype) results in the synthesis of proteins, and consequently, the physical traits of an organism (Phenotype). Deciphering GENs plays an important role in a wide range of applications from genetic studies of the origins of life to personalized healthcare. Probabilistic graphical models such as Bayesian Networks...
Nowadays, systems for various smart city industries such as city power plants, public transportation and integrated modular avionics are becoming increasingly complicated, with most of components being embedded and geologically distributed. In order to ensure the availability of target systems, prognostic and health management develops as an important system to assess the current health state and...
This research presents a scheme for explainable sleep quality evaluation utilizing the heart rate based sleep index. In the proposed model, the global covering rule induction of LERS (Learning from Examples based on Rough Sets) is used to generate rules associated with sleep quality status, such as ‘Bad,’ ‘Normal,’ and ‘Good.’ These rules are used to interpret the three sleep statuses. To show the...
We develop an intelligent credit rating system that can provide debtors' rating information without involving credit rating agencies. Several models are used for credit scoring in our work, including the Duffie's model, logistic regression, and random forest. We compare the performance of these models and build an in-depth understanding of the evaluation of credit rating. Furthermore, we propose a...
Three dimensional (3D) integration technology provides a great opportunity for reconfigurable device to improve performance, while the literatures for 3D reconfigurable device are lack of an efficient task scheduling and placement algorithm.
