Human Activity Recognition is a research field that aims to identify the activities carried out by a person. Recognition can be done by using information that is retrieved from various sources, for example: using inertial sensors. Lately, many people use smartphone with built-in inertial sensors such as accelerometer and gyroscope which make these smartphone capable of recognizing human activities...
This paper investigates the usability of Halftoning-based Block Truncation Coding (HBTC) feature for image retrieval. It assumes that all images in database are stored in scrambled/encrypted format. Firstly, an image feature descriptor is derived from the scrambled/encrypted image. This image feature is subsequently converted into the binary representation to achieve fast similarity measurement. The...
This paper presents a new method on image forensics application using the Error Diffusion Block Truncation Coding (EDBTC) feature. The image forensics tries to detect the copy-move forgery image regions on the forged image. Firstly, an image is divided into several non-overlapping image blocks. The image feature is further derived for each image block. Herein, two image features, namely Color Feature...
This paper proposes a new image watermarking scheme based on Generalized Singular Value Decomposition (GSVD). This image watermarking method embeds the principal components of watermark image into the host image using a specific scaling factor to control the imperceptibility and robustness aspects. Using this strategy, the GSVD-based image watermarking has ability to avoid the false positive problem...
Oil fuel is a vital necessity for the people of Indonesia. Government policy that diverts subsidy and transfers the prices to economic mechanisms can make fuel prices fluctuate irregularly so that it can bring startled to the public if it is not anticipated with preventive measures. One indicator influencing fuel prices in Indonesia is the Indonesian Crude Oil Price (ICP) so that the forecasting mechanism...
Ontology is a representation term used to describe and represent a domain of knowledge. Manually ontology development is currently considered complex, requiring a lot of time and effort. This research was proposed to develop methods to build automatic domain ontology bilingual in Indonesian and English by using corpus and ontology design patterns (ODPs) in tuberculosis disease. In this study, the...
Scheduling trains in order to minimize the traveling time is a challenging optimization problem. Delay may occur due to the bottleneck or many trains need to use the same track at the same time. These delays increase the journey time and may cause secondary delays to the other trains in the network. Double track railway scheduling can be modelled as a Job-Shop Scheduling Problem that can be achieved...
This article introduces a new method for detection of atrial fibrillation (AFib) using a support vector machine (SVM). AFib could lead to heart failure and stroke and thus an AFib early detection is very important. In this article, an SVM and variabilities of electrocardiographic heart rate are employed to detect AFib. Radial basis functions (RBF) is utilized for SVM. Different SVM constructions are...
A new technique for detecting atrial fibrillation (AF) is proposed and investigated. The technique employs a swarm fuzzy inference system (SFIS). SFIS is fuzzy system optimized by using a particle swarm optimization (PSO). The technique introduces new inputs for the SFIS to detect AF. The inputs involve the peaks number and width of electrocardiographic P-wave. Experiments of FA detection utilizing...
Wireless sensor networks (WSN) are used in a number of different applications including military, environment monitoring, smart spaces etc. Security is an important aspect in WSN, however given scare resources, implementing traditional cryptographic algorithms is not very well suited for WSN nodes. Hence watermarking is being investigated as an alternative security technology in WSNs because of its...
Wireless multimedia sensor networks (WMSNs) are an emerging type of sensor networks which contain sensor nodes equipped with microphones, cameras, and other sensors that producing multimedia content. These networks have the potential to enable a large class of applications ranging from military to modern healthcare. Since in WMSNs information is multimedia by nature and it uses wireless link as mode...
