The paper presents a method to determine a position of objects in three dimentional coordinates. The proposed method uses a vision-based localization using two low cost cameras. The formulation is derived by using a pin-hole camera principal to project a location of a point in a 2D image into 3D space. This method can be used for indoor unmanned aerial vehicles localization to provide position information for control and navigation purposes.

The number of VoIP users in Indonesia is very low, although the cost offered by VoIP is smaller than using pulsed phone. One of the reason is security provided by the VoIP service provider is still lacking. VoIP users have not received yet the security service to ensure the security of communications. This study tries to secure communications between VoIP users using encryption module that is integrated with VoIP client Sipdroid running on Android Smartphone. It is possible for VoIP users because VoIP client that can only be accessed by VoIP users. The result obtained after integration with encryption module using three encryption schemes, they are AES, DES, and RC4. Sipdroid able to resist passive attack from tapping information (eavesdropping) during the communication session. And the result of QoS measurements is an increase delay of 0.01 ms and no significant change in the throughput and the packet loss, for throughput generated about 78 kbps, and for the average packet loss is 0.8%. However there is a noise that follows the communication on Sipdroid integrated with the encryption module due to the wave skew from the increase time during the encryption process.

This paper highlights the authors' experiences teaching high school students Science-Technology-engineering-Mathematics (STEM) and technology literacy skills. Productive learning is engendered by trust, safety, supportive interpersonal relationships between mentors and students, and adaptation of teaching style to match the students' frame of reference. These principles are incorporated in the design of an online learning program called Best We Can Be. We discuss how technology-aided instruction encourages students to explore subject matter beyond their comfort zone. This fosters students' natural curiosity about STEM topics, and helps overcome their anxiety about whether they will be able to learn the subject matter. In Best We Can Be, students participate in structured, hands-on activities illustrating the cross-fertilization of academic disciplines (e.g., bioethics, which encompasses social, health and biological sciences, humanities, law, etc.) and their interdependency in society. We examine technology's enablement of student interactions within secure networks of mentors, experts, and peers. We discuss transformative impacts of broadening student appreciation of the world of possibilities that await them in future educational and career paths. The ultimate goal is for students to become self-motivated, life-long productive learners. © 2013 IEEE.

Revenues and profits from short life cycle products will depend upon careful formulation and execution of production plans in response to demands in the marketplace. This research contributes to the development of the production and inventory build-up strategies for short life cycle products under different demand-supply scenarios. A modified Bass diffusion model is used to characterise the product demand pattern with consideration of demand-sales interaction. We develop cost models based on production costs, inventory carrying costs, backlog costs, and cost of lost sales for a number of different production scenarios. The optimal production rate is obtained by minimising the total cost. We also investigate the benefit of an initial build-up of inventory before the product's sales period starts. © 2013 Inderscience Enterprises Ltd.

Wireless sensor networks can be applied to health care and disaster response, etc. The importance and accuracy of the information requirements of wireless sensors are more stringent. It corresponding to the use of information security should be taken seriously. The detection technology of intrusion detection system (IDS) will affect the lifetime of entire wireless sensor network (WSN). This study combines ontology with intrusion detection system to propose a lightweight ontology intrusion detection system (OWIDS). The system builds the relationship of sensor node in the ontology to detect Sybil attack firstly. The patrol node loads a part of the ontology to detect Sybil attack. Finally, the system uses the isolation table to continue isolation abnormal nodes to avoid duplicate detection energy-consuming. The preliminary experimental result shows that our proposed method can reduce the energy consumption for wireless sensor network intrusion detection, and improve the availability of intrusion detection systems. © 2013 ISSN 1881-803X.

The reliability on Safety Instrumented Systems (SIS) is critical for the safe operation of many industrial applications. In particular, SIS play an important role in oil and gas processing plants. SIS are responsible not only for the continuous operation of the plant, it also keeps the plant in a safe state, avoiding damages to the environment and minimizing risks to employees. Therefore, the correct behavior of such systems is an important goal to achieve when building industrial plants. Verification and testing of SIS programs is a very hard task to accomplish. This happens mainly for two reasons. First, testing the real system is very expensive and sometimes it may take a huge amount of time, weeks or even months. Second, those systems deal with a huge number of variables. It is not always possible for a human tester to check if all of them are correct when performing tests. Providing an automatic and formal testing approach for such systems is an important contribution for the development of such systems. In this work we introduce a new method for generating test cases for SIS programs running on programable Logic Controller (PLC). As we did on previous work, ISA 5.2 diagrams are used as specification of the systems, but now we are using a hardware-in-the-loop technique, and the target artifact is a software running on a PLC. To avoid the execution of redundant tests, we introduced a new test case generation algorithm that is based on equivalence classes. Finally, we discussed a study case in which our method is used to detect error, that were introduced on purpose, on a simple system.

Generally, playing music tones can be done in two ways, melody and chord. Chord is a harmonization of three or more pitch that sounding simultaneously. In MIDI, one command only for sounding one tone. For chord, need three or more command that run together. If implemented in an application, the formulation is required. So MIDI commands can be generated by the program without having to write MIDI commands one by one manually. © 2012 IEEE.

The biggest challenge for text and data mining is to truly impact the biomedical discovery process, enabling scientists to generate novel hypothesis to address the most crucial questions. Among a number of worthy submissions, we have selected six papers that exemplify advances in text and data mining methods that have a demonstrated impact on a wide range of applications. Work presented in this session includes data mining techniques applied to the discovery of 3-way genetic interactions and to the analysis of genetic data in the context of electronic medical records (EMRs), as well as an integrative approach that combines data from genetic (SNP) and transcriptomic (microarray) sources for clinical prediction. Text mining advances include a classification method to determine whether a published article contains pharmacological experiments relevant to drug-drug interactions, a fine-grained text mining approach for detecting the catalytic sites in proteins in the biomedical literature, and a method for automatically extending a taxonomy of health related terms to integrate consumer-friendly synonyms for medical terminologies.
