Along with the wide spread of mobile devices to access the Internet from anywhere at any time, the smartphone application market has been growing with amazing speed. The study of usages of smartphone applications by individual users, however, has been rather limited in the literature, relying upon real data collected from either a limited number of volunteers or the network level information at the...
Alzheimer's Disease (AD) is the most common form of dementia, affecting approximately 10% of individuals under 65 years of age, with the prevalence doubling every 5 years up to age 80, above which the prevalence exceeds 40%. Currently diagnosis of AD is largely based on the examination of clinical history and tests such as MMSE (Mini-mental state examination) and PAL (Paired Associates Learning)....
Sustainable economic growth and appreciable living standard in a country heavily depend on the reliability and efficiency of its transport infrastructure. One possible way of enhancing the travel experience of commuters is by using intelligent applications in vehicles that communicate through wireless networks. Envisioning these applications to new heights can be achieved with the recent advancements...
With the flooding of low-cost UAVs to the consumer market, there is a rejuvenated interest to develop applications using consumer UAVs to enhance the quality of day to day lives of us humans. However, the limited capacity with respect to memory and processing power makes adopting a consumer UAV to advanced tasks such as object detection and tracking challenging. The modern day object tracking quadcopters...
Usability plays a major role towards user acceptance of website and it is increasingly becoming an important topic for organizations that develop and implement websites to market their products and services. Thus evaluating usability is critical for organizations in order to develop user friendly websites. One major challenge in usability evaluation is that most of the evaluation methods are subjective...
Service Oriented Architecture (SOA) and Software Product Line (SPL) have individually proven to be Software Engineering concepts, which are creating values for developing software systems. While SOA is being used for developing applications from an orchestration of web services, SPL has ability to prepare core sets of assets and manage with variable components. The combination of SOA and SPL has highlighted...
Internet of Things (IoT) is an evolution of the current Internet into a ubiquitous network of interconnected objects which collects inputs through the sensing mechanisms and takes actions based on those inputs. Fuelled by the falling costs of the sensors, streams of raw data is transmitted to the IoT network continuously which is voluminous in the scale of Big Data. This puts an immense value on the...
Smartphones have become a tremendous influence on human lives over the past decade. With attractive and advanced features integrated into smartphones, they are now considered more as a handheld computer than just a mobile phone. Driven by these improvements and desire for the latest devices, consumers replace their smartphones in a rapid rate, increasing the number of discarded devices. Fortunately,...
Nowadays, many applications require to represent both data and knowledge together. Regardless of the requirement, the normal practice is either using only database or only ontology. These approaches are proven to have drawbacks. There is still no proper methodology to obtain the benefits from both ontology and database management systems together. The issues raised by the rapprochements between such...
This industrial research paper outlines an outcome of a machine leaning approach to dynamically generate context sensitive Application User Interfaces (Adaptive UI) on top of a monolithic enterprise software product.
This paper describes a system to answer a specific sentiment analysis problem described in 2015 iteration of SemEval (Semantic Evaluation series), Sentiment Analysis in Twitter as the base challenge to be improved. When it comes to sentiment analysis competitions and shared tasks, this is the most popular to date with more than 40 teams participating each year from its inception in 2013. Only subtask...
The landscape of personnel recruitment has been changed with the emerging trend of online approaches whereas the past custom was accompanied with face to face interview approach with time consuming process flows in recruitment decision making. Online interviews can be used as an initial study to the formation of first impressions for initial screening and shortlisting purposes. Therefore, in this...
The 2D Ising model obviously deals with mass data to study the behavior of magnetization and energy related with temperature. This simulation should be worked out efficiently in terms of cost, time and memory consumption. In this paper, we introduce an innovative technique that executes bits instead of integers in order to reduce memory usage (1/32) and turnaround time (0.53). This approach has been...
The management of Sri Lankan school and club level cricket board faces the challenge of dealing with match statistics in match analysis using manual methods. The analysis of previous cricket matches is time consuming and messing up due to lack of technology. The aim of this research is to upgrade the Sri Lankan school cricket with the blend of information technology to solve the existing problems...
Multiple sequence alignment (MSA) methods infer the homologous regions within DNA and protein sequences. Among the other algorithms for MSA, the center star method (CSM) is useful when processing a large number of sequences. In this method, the partially conserved regions among the non-center sequences tend to hide in the alignment. Therefore, existence of subsets of similar sequences in the input...
Cancer is the second leading cause of death in children (after accidents). Childhood Acute Lymphoblastic Leukemia (ALL) is the most common and high risk cancer among the children. Medical practitioners make predictions about the survival time using their previous experiences and observations. They still cannot give an accurate survival prediction since the relationship between health status and survivability...
