Reverse unknown protocol's hidden behavior has played an important role in the field of network security. The proposed work takes the captured messages and the binary code that implement the protocol both as the studied object. Dynamic Taint Analysis combined with Static Analysis is used for protocol analyzing. Firstly, monitor and analyze the process of protocol program parses the message in the...
The Pub/Sub, short for Publish-Subscribe, is a flexible mechanism perferred by many users who'd like to passively know the changes of situation. Once a new message is published by a provider, all the subscribers to the specific kind of messages will receive the message and make corresponding responses. In agricultural crop monitoring, such mechanism is very helpful in enhancing the efficiency of message...
Timely, frequent, crop vegetation condition information, with complete geospatial coverage acquired throughout the growing season is critical for public and private sector decision making that concerns agricultural policy, production, food security, and food prices. The NASA Soil Moisture Active and Passive (SMAP) mission provides such a reliable data source for cropland soil moisture assessment....
A health monitoring system is proposed with the aim to provide health monitoring with minimal location and time constraint for the elderly. The challenges in continuously monitoring health faced by conventional medical practice is expected to be solved using this vest-based system, as it is capable to obtain health parameter from its wearer and channel it to a remote web and database server anytime...
The energy consumption had grown deeply in the entire world. In Brazil, although the economic growth in the last years had been underwhelming, the energy consumption rate continues high. Recently, at the beginning of the year 2015, meaningful adjusts had been done at the energy tax. Especially on the state of Santa Catarina, the National Agency of Electrical Energy of Brazil (ANEEL) approved a readjustment...
The Secure Autonomous Response Networks (SARNET) framework introduces a mechanism to respond autonomously to security attacks in Software Defined Networks (SDN). Still the range of responses possible and their effectiveness need to be properly evaluated such that the decision making process and the self-learning capability of such systems are optimized. To this purpose we developed a touch-table driven...
We describe the architecture, problems and lessons learned from building a Health Kiosk from commercial, off-the shelf Personal Health Devices and a computer with a touch-screen interface. The kiosk is used autonomously by patients to measure vital data prior to a consultation, in the scope of a population screening, or for routinely monitoring. The prototype was tested in multiple events with different...
Sensus Ekonomi 2016 (SE2016-Economy Census 2016) which will be held in 2016 is an important and massive activity. Badan Pusat Statistik (BPS-Statistics Indonesia) taking main responsibility needs to arrange strategic and appropriate actions for the success of the event. One of the actions that can be used to support SE2016 implementation is by providing information about progress of SE2016. Therefore...
Blood pressure measurement serves as a pivot for diagnosis of cardiovascular conditions and is done conventionally using sphygmomanometer. However this method has the limitations of producing only fewer readings in a given time and causing patient discomfort. Hence there is a need for blood pressure measurement procedure that can give more readings in a given span of time and with utmost ease. We...
We study the potential of reflectance photoplethysmography (PPG) in monitoring free flaps for arterial and venous thrombosis in post-surgical scenarios. Circulatory disruptions due to thrombosis were simulated using limb ischemia method on 30 volunteers. Arterial and venous occlusions were conducted in this study. The variation in blood flow in the region of interest was captured by a custom built...
Bridging the digital divide has recently become the primary goals of any developing country as technology is increasingly being linked to development. Many developing countries have set up initiatives that focus on using Information Communication Technology (ICT) to bridge this gap in a visible future. However, a lot still needs to be done in ensuring that ICT solutions are relevant. Service Oriented...
Following a surgical procedure, patients are monitored in an ICU until physically stable, after which are discharged to a ward for further evaluation and recovery. Usually, ward evaluation does not imply continuous physiological parameters monitoring and therefore patient relapse is not uncommon. The present paper describes the steps taken to design and build a low-cost modular monitoring system prototype...
A survey conducted by The United States Department of Health and Human Services (2014), reported that 3.6 million children are victims of child abuse that occurred in the country. In fact, not only in U.S, but child abuse also occurred in around the world, especially in areas with high children population. Monitoring systems became an important and popular in the era of technological development....
According to the theory of non-relativistic electron beam can produce high harmonic wave, a new type of terahertz source—high harmonic traveling wave tube was designed and fabricated. Simulation shows the device can deliver 144.5W@138GHz with 300mW@46GHz input signal. The beam voltage is 18.4kV and the beam current is 120mA. The prototype tube is developed and will be test in near future.
Software Defined Networking (SDN) is a promising architectural approach based on a programmatic separation of the control and data planes. For high availability purposes, logically centralized SDN controllers follow a distributed implementation. While controller role features in the OpenFlow protocol allow switches to communicate with multiple controllers, these mechanisms alone are not sufficient...
Network flow monitoring is being supplemented with an application flow visibility to provide more detailed information about network traffic. However, the current concept of flows does not provide a mechanism to keep track of semantic relations between individual flows that are created as a part of a single user action. We propose an extension to the flow measurement, called EventFlow, which allows...
In this paper, we present improvements toward a wearable prototype for breast health monitoring using microwaves. The system operation is based on multistatic radar, with the 16 sensors embedded in a wearable bra. Measurements are recorded in the time-domain, over a frequency range covering 2 – 4 GHz. A wearable system offers several advantages over a table-based system, including lower-cost, adaptability...
This paper presents an overview of a novel non-invasive device for detection of glucose variations in water solutions in the range 56 – 61 GHz. The system is in lab prototype stage and with the use of a PNA, glucose variations can be correlated to transmission measurements through the solutions. Experiments indicated that higher power levels at the receiving side account for higher glucose concentrations...
Global energy consumption has risen drastically. In Brazil, although economic growth in recent years has been underwhelming, the growth rate of energy consumption has steadily risen. At the beginning of 2015 important adjustments were made to the energy tax. Within the state of Santa Catarina, in particular, the National Agency of Electrical Energy of Brazil (ANEEL) approved a readjustment of 43%...
All along changing connectivity requirements and new technologies have increased the complexity and dynamism of distributed system, thus presenting tough challenges for the network management and the network security. As a result new ways for monitoring and managing of security events are required. We present a novel idea how to exploit the software defined networking (SDN) and the real-time network...
