Article
User‐level file systems are usually adopted to bridge the gap between efficacy and efficiency of file system developments for new applications' I/O demands. And the widely known user‐space file system framework, FUSE, is commonly utilized to deployed user‐level file systems. This article first uses a popular stack‐able file system as a case study t...

Augmented reality (AR) applications that overlay a user's perception of the real world with digitally generated information are on the cusp of commercial viability. AR has appeared in several commercial platforms like Microsoft HoloLens and smartphones. They extend the user experience beyond two dimensions and supplement a user's normal 3D world. A...
Article
The recent proliferation of IoT device coupled with the demand for an inexpensive way of transmitting data has been the primary factors behind the popularity of the short-range acoustic communication. It enables a seamless transfer of digital information via soundwaves, using device’s loudspeaker and microphone only and the whole interaction takes...

Achieving high QoE for AR applications on a mobile device is challenging because the required advanced computer vision and machine learning algorithms are computationally intensive by nature. Hence, some task for AR applications must be offloaded to more powerful remote servers. Offloading for mobile applications remains an active area of research....

Crowdsourcing is a technology with the potential to revolutionize large-scale data gathering in an extremely cost-effective manner. It provides an unprecedented means of collecting data from the physical world, particularly through the use of modern smartphones, which are equipped with high-resolution cameras and various micro-electrical sensors. I...

Lack of an accurate and low-cost method to reconstruct indoor maps is the main reason behind the current sporadic availability of digital building floor plans. The conventional approach using professional equipment is very costly and only available in the most popular areas. In this paper, we propose and demonstrate CrowdMap, a crowdsourcing system...

Remarkable progress was made with smartphones in the last few years. Modern smartphones are now equipped with high-resolution cameras and various micro-electrical sensors that open up new mobile application possibilities. In this work, we address a critical task of reconstruct indoor large-scale 3D model from crowd-sourced images. We propose, desig...

The typical usage for phones is making calls. However, under certain scenarios, phone calls are inappropriate or intrusive when people are having a meeting, impractical when background noise level is too high or insecure under monitoring of other personals/parties. Typical solution to these problems is to send text-based messages. Yet, we argue tha...

Short-range wireless communication technologies have been used in many security-sensitive smartphone applications and services such as contactless micro payment and device pairing. Typically, the data confidentiality of existing short-range communication systems relies on key-exchange then encryption mechanism, which is inefficient, especially for...

Short-range wireless communication technologies have been used in many security-sensitive smartphone applications and services such as contactless micro payment and device pairing. Typically, the data confidentiality of the existing short-range communication systems relies on so-called “key-exchange then encryption” mechanism, which is inefficient,...

Many popular location-based social networks (LBSNs) support built-in location-based social discovery with hundreds of millions of users around the world. While user (near) realtime geographical information is essential to enable location-based social discovery in LBSNs, the importance of user location privacy has also been recognized by leading rea...

Grade classification of seed cotton is a major problem that has an significant impact on the agricultural economy. According to characteristics like impurities, yellowness and brightness that extract from images of seed cotton, constructing classification model of seed cotton base on the least square method. Using support vector machine regression...

Force feedback is a good opportunity for virtual reality technology (VRT) into the field of engineering simulation. Haptic device point (HIP) is the common tool used for interacting with the virtual objects, while the mass-spring model consistent with which does not have good scalability, and cannot guarantee the necessary accuracy. By substituting...

Harris Corporation and the State University of New York at Buffalo are conducting a collaborative project to develop an HF network simulation framework based on the ns-2 open source network simulator. The framework will contain models of HF channel characteristics, waveforms, protocols, and typical traffic loads, so as to be useful for analyzing HF...

The article first models the relationship between the growth of plants and the population of pest. Because the growth rate of plants in the greenhouse can be easily affected by pest infestation and the population of pest is related to the number of plants since plants are their food source. As for the pest control, the article describes two common...
