Accurate deep learning-based segmentation of retinal arteries and veins (A/V) enables improved diagnosis, monitoring, and management of ocular fundus diseases and systemic diseases. However, existing resized and patch-based algorithms face ...

Surface sensing is widely employed in health diagnostics, manufacturing and safety monitoring. Advances in mobile sensing affords this potential for context awareness in mobile computing, typically with a single sensing modality. Emerging multimodal ...

This paper presents Z-Ring, a novel wearable device that uses radio frequency (RF) based sensing to offer unique capabilities for human-computer interaction, including subtle input, object recognition, user identification, and passive surface ...

The growing importance of technology in daily life has led to a focus on making robots think like humans to enhance the integration of humans and robots in Cyber-Physical Systems (CPS). Cognitive science and psychology offer important knowledge ...

Ubiquitous networks comprise a diverse set of homogeneous or heterogeneous networks to perform ubiquitous computing operations. In the real-time application context, users can access data from any place and at any time by using mobile devices/...

As private data is key to applications in the field of Ambient Assisted Living, access control has to be in place to regulate data flows within the environment and to preserver the privacy of a user. We present a data access control system based on an ...

Context-aware mobile application (App) usage prediction benefits a variety of applications such as precise bandwidth allocation, App launch acceleration, etc. Prior works have explored this topic through individual data profiles and contextual ...

An increasing number of devices are getting enough computing and storage capacity to adapt their behaviour to the needs and preferences of their users. However, in multi device systems, this will require new techniques allowing several devices to take ...

In this study, we propose AOBAKO, a testbed for context-aware applications, which focuses on the testing of mobile applications using Bluetooth Low Energy (BLE) for indoor positioning. AOBAKO emulates BLE-beacon communications based on accurate frame-...

Mobile applications may benefit from context awareness since they incur to context changes during their execution and their success depends on the user perceived quality. Context awareness requires context monitoring and system adaptation, these two ...

With the rapid development of Internet of Things IoT and mobile technologies, the service offerings available in the IoT and mobile environments are increasing dramatically. How to provide intelligent and personalized services for users becomes a ...

Ecommerce systems employ recommender systems to enhance the customer loyalty and hence increasing the cross-selling of products. In collaborative filtering-as the most popular method in recommender systems-an implicit network is formed among all the ...

Stand-alone and networked surgical virtual reality based simulators have been proposed as means to train surgical skills with or without a supervisor nearby the student or trainee. However, surgical skills teaching in medicine schools and hospitals is ...

One of the major drawbacks of mobile nodes in wireless networks is power management. Our goal is to propose an adaptive rate adaptation algorithm with the integration of power control scheme that will minimize energy consumption by appropriate ...

The Operating System (OS) manages the hardware resources of a computer. For an OS, the knowledge about context is valuable information in optimizing its tasks. Recent mobile devices, such as smart-phones and tablets, are providing new avenues in context ...

Researches on Ambient Intelligent and Ubiquitous Computing using wireless technologies have increased in the last years. In this work, we review several scenarios to define a multi-agent architecture that support the information needs of these new ...

Test-based assessment tools are mostly focused on the use of computers. However, advanced Information and Communication Technologies, such as handheld devices, opens up the possibilities of creating new assessment scenarios, increasing the teachers' ...

Electronic learning(e-learning) is used to access the learning content using desktop computers. But the limitation with e-learning is its immobility. Mobile learning(mlearning) is an advanced stage of e-learning where in the learner is equipped with ...

To provide effective mobile services in spite of network disruption, context aware middleware services on mobile devices and application servers can provide services for continuation of applications, by managing mobile services, network connection, ...
