It is usual for a consumer to search a product based on its category and go to related kind of shop to buy a product, e.g. food in supermarket, a pencil from a stationary shop and etc. While it is not uncommon nowadays for a shop to sell various categories of goods at the same time, like a newspaper stand do sell toys, an accessory shop has stationary. However, consumer may not easily notice and purchase...
Due to the geomagnetic abnormality in indoor environment, made by various ferrous structural materials such as pipelines, the magnetic signals of a region are regularly different and sustainable. In this paper, we develop an application based on the Android system to implement the indoor geomagnetic positioning. To estimate the pedestrian's position, the real-time geomagnetic sequence measured by...
We present a system prototype aimed at lowering the burden of grocery shopping by recommending products according to those currently in a shopping basket, and supporting users in finding their way from their current position to the location of a determined item within the store. On the backend side, retailers can reflect changes in the location of inventory and shelf distribution in the store. These...
Assembly execution trace analysis is an effective approach for discovering potential software vulnerabilities. However, the size of the execution traces and the lack of source code makes this a manual, labor-intensive process. Instead of browsing billions of instructions one by one, software security analysts need higher-level information that can provide an overview of the execution of a program...
Frappé is a code comprehension tool developed by Oracle Labs that extracts the code dependencies from a codebase and stores them in a graph database enabling advanced comprehension tasks. In addition to traditional text-based queries, such context-sensitive tools allow developers to express navigational queries of the form Does function X or something it calls write to global variable Y? providing...
In the paper, a location-based reminder application iDoRemind is developed to assist people in remembering and managing their everyday activities. iDoRemind overcomes the weakness of the existing location-based reminder applications by repeated alerting the user and suggesting the alternative locations based on users' preferences and their current location. The suggested locations are ranked according...
Due to the emerging Big Data paradigm, traditional data management techniques result inadequate in many real life scenarios. In particular, the availability of huge amounts of data pertaining to social interactions among users calls for advanced analysis strategies. Furthermore, heterogeneity and high speed of this data require suitable data storage and management tools to be designed from scratch...
The current ship reporting procedures are a little cumbersome, a large number of ship reports increased the burden of the ship's officer, to a certain extent, affecting the safety of navigation. In order to simplify the ship reporting procedures and reduce the workload which brings to the ship officer, under the background of the e-navigation construction advocated by IMO (International Maritime Organization),...
In order to achieve sustainability in the context of advances in science and technology, it is necessary to transform the traditional tourist attractions into smart tourist attractions by combining smart and information technologies with scientific management. Navigation and guide is an important module of smart tourist attraction. A navigation and guide service system based on smart phone is proposed...
The GOES-R Flight Project has developed an Image Navigation and Registration (INR) Performance Assessment Tool Set (IPATS) for measuring Advanced Baseline Imager (ABI) and Geostationary Lightning Mapper (GLM) INR performance metrics in the post-launch period for performance evaluation and long term monitoring. IPATS utilizes a modular algorithmic design to allow user selection of data processing sequences...
Physical exercising has always had an important impact on humans' health. Lack of motivation is one of the major reasons that keeps a person from exercising. To overcome this problem, new solutions are needed to provide weight watchers and fitness seekers motivation to exercise indoors. This paper presents iGym, a low cost and flexible system that enhances humans' workout experience. This system lets...
Increasing the safety of a navigation lock, by creating a modern and efficient communication between the human operator and the machine, for a prompt and accurate information offered to the operator, about the status of the equipment it serves, it is a requirement of today navigation worldwide. This paper aims to describe the implementation of a modern and efficient centralized tracking equipment...
In recent years, see-through display technology has begun to reach a point where we will have the ability to continuously display virtual information in a variety of real world situations. However, augmented reality (AR) interfaces are currently limited in their ability to interact with the wearer and environment to provide specific, safe, and useful information when needed. Moreover, many questions...
Navigation maps provide important information for Advanced Driving Assistance Systems (ADAS) and Autonomous Vehicles. This paper presents a method estimating a set of likely map-matched hypotheses containing the correct solution with a high probability. This addresses the problems encountered when using a high definition map when a large number of ambiguities arise. These occur for instance, when...
Smart parking solutions for big cities are critically important for reducing traffic congestion and vehicle energy consumption in big cities. Visual-based detection methods have been proposed since their maintenance costs are typically lower. However, visual based detection methods in existing systems are not robust due to varying light intensities, occlusions, and their deployment costs can still...
This paper presents the usability study of a cooking application, KitchenGeek with a wearable device, Smart M between two user groups, beginner and intermediate cookers to test if the application and device lowers the gap of time taken for both of the user groups to complete the cooking tasks. The results of this paper indicates that KitchenGeek and Smart M did lower the gap of time taken for task...
A random-walk-based (RW-based) information search makes a single query or multiple queries walk around a network to search for the target information. Local navigation rules, based on which a query chooses an adjacent node to move from the current location, are important for increasing the search speed of the RW-based information search. In the present paper, we focus on degree-dependent navigation...
The clock bias in different sectors of a cellular base transceiver station (BTS) cell is studied. A dynamical model relating the clock biases in different BTS sectors is identified and validated experimentally. A theoretical estimation error lower bound due to the discrepancy between sector clock biases is derived and demonstrated against Monte Carlo simulation runs. Experimental results of an unmanned...
We consider in this demonstration the analysis of complex data-intensive applications. We focus on three classes of analytical questions that are important for application owners and users alike: Why was a result obtained? What would be the result if the application logic or database is modified in a particular way? How can one interact with the application to achieve a particular goal? Answering...
The performance of GPS (Global Positioning System) in densely built urban areas is greatly undermined due to multipath propagation. Many attempt alternative means for urban navigation, of which the ‘fingerprinting’ method has drawn much attention recently. However, the labor of site surveys and a constantly changing environment prevents ‘fingerprinting’ from being an eificient solution. Therefore,...
