Assessment feedback, which is an important factor in student learning development, has been a source of dissatisfaction for many years. The technology used in universities such as Gradebook does not allow the tracking of student engagement with their feedback. In general, engagement is mainly reported via observation or students' self-report. This paper presents results from using a prototype application...
Existing techniques used for anomaly detection do not fully utilize the intrinsic properties of embedded devices. In this paper, we propose a lightweight method for detecting anomalous executions using a distribution of system call frequencies. We use a cluster analysis to learn the legitimate execution contexts of embedded applications and then monitor them at run-time to capture abnormal executions...
Nowadays, Cloud providers revise the terms of their Service Level Agreements (SLAs) to include security provisions due to their criticality for their customers. In order to speed up their adoption by service providers and consumers and to make them more actionable, security SLAs monitoring should be described in a machine-processable, agile and extensible way. Several tools for SLA management are...
Augmented Reality (AR) is a technology that augments the real physical world with computer-generated 3D virtual objects such that the users can interact with them using the screen of their mobile devices. This paper studies how to effectively use AR to enhance the learning experience of kindergarten students, while addressing parents' concern that a long-time usage of electronic devices may affect...
Bees are an important part of our echo system. Pollinators, such as bees, help at least 30% of the worlds crops and 90% of the worlds wild plans to thrive via cross-pollination. Studies show that between 2015 and 2016 beekeepers lost 44% of bee colonies over the winter, this is up about 10% from the previous decade. Causes for this decline is correlated to the overall hive health. The healthier the...
This paper describes development of flexible RFID smart tag for temperature monitoring. The system is based on a single chip solution working at 13.56 MHz according to ISO 15693. This standard is supported by Android API and Android smartphones with NFC periphery. The developed prototype of the smart tag was realized by hybrid technology combining printed RFID antenna with the SMD chip and flexible...
This work describes the development of a nanotechnology solution for the non-invasive detection and monitoring of diseases, such as asthma, by identifying and measuring the concentration of nitric oxide (NO) in exhaled breath. Nitric oxide is a known breath biomarker and the medical literature has published, recently, guidelines correlating the amounts of NO in breath with various airway diseases...
This experience paper describes the process of leveraging the NFV orchestration platform built in the EU FP7 project UNIFY to deploy a dynamic network service exemplified by an elastic router. Elasticity is realized by scaling dataplane resources as a function of traffic load. To achieve this, the service includes a custom scaling logic and monitoring capabilities. An automated monitoring framework...
With cloud computing consolidation, Platform-as-a-Service (PaaS) has been used as a solution for developing applications with low cost and maximum flexibility. However, an open challenge related to PaaS is the proper handling of multi-tier and stateful applications with support for high availability (HA); and scalability can be considered an essential feature for HA. However, dealing with several...
Consolidating applications of conflicting service level objectives (SLOs) to share virtualized resources in cloud datacenters requires efficient resource management to ensure overall high Quality-of-Service (QoS). Applications of different performance targets often exhibit different resource demands. Thus, it is not trivial to translate individual application SLOs to corresponding resource shares...
More and more devices are nowadays connected all over the world creating a complex grid that generates large volume of data. This is enhanced by various smart metering applications that collect, process, analyze heterogeneous data sets and extract valuable information to their owners. Apart from conventional energy meters that provides only monthly feedback regarding the total consumption, smart meters...
Failures of precondition checking when attempting to apply automated refactorings often discourage programmers from attempting to use these refactorings in the future. To alleviate this situation, the postponement of the failed refactoring instead its cancellation is beneficial. This poster paper proposes a new concept of postponable refactoring and a prototype tool that implements postponable Extract...
This paper describes the development of an immersive VR application that lets visual artists quickly visualize and prototype their pictorial design ideas in virtual environments. First, the design requirements are outlined and then the implementation of the application prototype in Unreal Engine 4 is explained. We perform preliminary user tests and discuss the feedback, as well as further improvements...
Current mobile revolution is leading to an increase of wearable health devices development and consequently a growth in ambulatory monitoring area. These systems can be applied in ambulatory diseases management and diagnosis, personal health monitoring or sports performance enhancement, providing physiological and body-area ambiance data during daily normal activities. Nowadays several devices in...
Nowadays, the civil, business, and industrial electrical power loads in Indonesia are growth rapidly. The main growth is in non-linear load as source of current harmonic which causes serious problem in power quality and safety of electric power system. To solve the problem, power quality monitoring system which is integrated with more effective measurement, control, communication, and supervision...
A novel wearable sensor system for seizure monitoring of neonates comprised of smart clothing, video recording and cloud platform is presented. Textile electrodes and Inertial Measurement Unit (IMU) are embedded in the smart clothing to obtain ECG signal and motion signal whereby epileptic seizure detection algorithm is performed. Moreover, a video monitoring module provides real-time information...
Respiration rate is monitored in most diseases, especially ones like sleep apnea and respiratory arrest. However, most devices available for monitoring are expensive, fragile and often need trained staff for operation. For obvious reasons, constantly monitoring the patient's breathing rate is also not feasible and our proposed module tends to modify this scenario. The hardware module uses a thermistor...
This paper presents the design of a modular, Scalable Enhanced Road Side Unit for use as part of a comprehensive Intelligent Transportation System based on the concept of Internet of Things (IoT). The proposed unit is designed to collect information using a variety of sensors and an on-board camera. The collected information can then be uploaded to a central server for actions such as speed limit...
The development of remote control technology has grown rapidly along with the development of communication technology nowadays. The simplest communication technology available is by using GSM protocol. In this paper, a prototype of electric appliance control tool via SMS by using GSM is proposed. GSM protocol was chosen because it does not depend on mobile devices' platform. GSM SIM 900 and Arduino...
This paper presents the design and implementation of the ALICE O2 Control System prototype. The design of our system is based on the ALICE O2 requirements. The system allows the crew operating the experiment to send simple commands in order to control the ongoing processes running in the computing farm. The sent command is capable of reacting to changing conditions and operational the requirements...
