A spell checker is a tool to check the spelling of words in a document, validate them and in case of finding error in spelling, list out the possible words as suggestions. There are several researches available on spell checkers for European languages and Indian languages. But few for Tamil language, maybe, because of its nature as it is a highly inflectional and complex language. An efficient error...
Oil is one of the most crucial commodity and energy resource that guarantee the evolution of the economy and industry of a country. The price fluctuation of the oil would be the emerging factor to be concerned and discussed generally in political and economic circle in each and every country. In Sri Lanka also the problem would be same when it comes to oil industry and its influencing factors for...
This research work presents new trends in cyber threats, and it also quantifies user awareness of web threats and attacks. Using an online questionnaire information for the analysis of whether individuals had adequate knowledge of internet threats and attacks in order to safeguard themselves was obtained. The survey showed that many users lack an adequate understanding of what to do and what not to...
Engaging in physical exercises such as weight training and physiotherapy stretching exercises at home requires proper execution and awareness of the exercises. One of the main problems in engaging exercises at home is that there is no proper guidance and feedback provided to align the exercises to the correct movements due to the absence of a physical trainer. This paper discusses how a system, namely...
On-going progressions of Information Technology increase the scope for computer vision-based interventions to facilitate efficient and promising technology for people with disabilities. This project aims to develop a wearable navigational assistive device, titled EyeVista, to facilitate visually impaired sprint athletes. It is a lightweight, easy-to-use, customizable and low-cost wearable jacket built-in...
A unique solar photovoltaic module connected instant power supply (IPS) system with intelligent priority based load distribution system has been designed in this project. Here the solar panels will be connected through an MPPT charge controller to the battery of an existing IPS (Instant Power Supply) which is common in urban areas where power cut is a common phenomenon. This battery will deliver alternating...
We propose a novel system that collects air sampling field data for a given location in 3D space. A drone mounted with relevant components for air quality measuring is deployed. Data collected from the system will be efficiently transmitted to the storing and monitoring devices. Knowledge of existing air pollutants levels and patterns are taken into consideration in order to analyse a given situation...
Aircraft design consists of many steps such as an aerodynamic design, structural analysis and flight control design etc. And flight control is one of the crucial design aspects in modern aircrafts. Modern day aircrafts heavily rely on automatic control system for most of the functions and there is always a persistence demand for efficient controllers. There are many control techniques and methods...
This work outlines an Intelligent Navigation System (INS) for autonomous robots. The primary focus of the proposed INS is to provide a logical, computationally efficient algorithm which serves as a basis to map and navigate unknown environments. For demonstrative and testing purposes, the INS was implemented both in simulation form using MATLABTM™ SIMULINK™ as well as practically, using an omni-directional...
Customers want fast checkout systems and retailers are always searching for ways to improve store checkout systems. The length of time the consumer spends waiting in line at the checkout counter makes an influence on consumer-buying pattern. Nevertheless, there is an overwhelming need for businesses to value customers' time and install more efficient checkout systems to improve the efficiency of queues...
This work presents a multi-sensor fusion approach for an electronic navigation aid for the blind and visually impaired persons. This approach proposes to intelligently fuse the surrounding information senses via ultrasonic sensors and vision sensors. The intelligent component of the prototype serves in several facets including object detection and recognition. Extended Kalman filter is used to fuse...
With Moore's law in effect, as the complexity of digital electronic circuits increases, the amount of time spent by the electronic design automation (EDA) tools to design such circuits also increases. It brings us to the point, where we need to improve the performance of EDA algorithms to fulfil the present and the future requirements of the EDA industry. Out of many algorithms used by these tools,...
Using eyes as an input device for different control backgrounds is the great research area of concern for enhancing the wide scope of human robot interaction. Interface design requirements in like that implementations are relatively different rather than conventional application areas. Both desired command input and sensory feedback responses may be achieved by human eyes instantaneously. In the direction...
Side Channel Attacks are a popular modern cryptanalysis technique used by adversaries in embedded devices to break the security key. In these types of attacks, the attackers are keen on identifying the weaknesses of the physical implementation of the cryptosystem and utilize such vulnerabilities to extract the key. Power Analysis Attack is a form of Side Channel Attack in which, the adversary exploits...
Smart attachment mechanisms are believed to contribute significantly in stiffness control of soft robots. This paper presents a working prototype of an active Velcro based stiffness controllable fastening mechanism inspired from micro active hooks found in some species of plants and animals. In contrast to conventional passive Velcro, this active Velcro mechanism can vary the stiffness level of its...
The Foreign Currency Exchange market (Forex) is the largest financial market in the world with the highest daily trading volume. A highly volatile complex behavior is seen during the time the market is open and understanding market trend patterns solves an enormous amount of problems pertaining to prediction and decision making. Many often traders write trading strategies to identify the significant...
Wireless Sensor Network (WSN) based acoustic monitoring is useful for ecologists for the purpose of monitoring real-time wildlife behavior across remotely located large areas, for long periods and under variable weather/climate conditions. However, stringent requirements for intense data processing and data bandwidth across network nodes makes applicability of WSN based monitoring limited. This paper...
Since recently, UAVs (Unmanned Aerial Vehicles) have increasingly been recognized as a reliable, and effective means of aerial surveillance. Deployment of UAVs in disaster management for aerial surveillance and real-time video feed, when land access is cut off, is one of the most prominent applications. The ability of small, lightweight UAVs in aerial access and gathering data, in areas that are insecure...
Advances in technology have enabled wireless devices to monitor and provide information than ever before. These sensors/actuators can be incorporated into any device to provide the user an immersive experience which include services such as connected-consumer, e-Health and smart transportation etc. Bluetooth Smart has emerged as popular wireless communication technology for such devices. The Received...
