In this study, segmentation of medical images is implemented by an edge-based level set approach based on the client-server communication. In the method, a medical image, which is already loaded into the image gallery of the smartphone by the user, is selected, the pathological region to be segmented is roughly marked and then both the input image and the marked region, and some input parameters used...
In today's rapidly evolving world of information and technology, software that tries to respond to growing demands is used in many industries. Everything can be made easier and faster with mobile platforms and smart PCs that almost everyone now has. Different types of technology can be managed and used, in various area such as shopping, banking, education. In this study, a mobile software was developed...
Innovations in technology that have enabled efficient wireless tiny devices propelled the concept of Internet of Things. It is expected that mobile data traffic will experience 8-fold growth between 2015 and 2020 and the number of mobile connected devices will reach 11.6 billion by 2020. Main factors of this exponential growth and wide acceptance are the integration of several technologies and communications...
Today, information technology has been used frequently in the veterinary field. Storage, information gathering and interpretation processes are realized by transferring the related field data to digital medium. In this context, expert systems provide important implications for symptom-disease relationship. In the study, the symptoms obtained from the pets are evaluated by the expert system and the...
With he rapid development of the mobile Internet industry, information security based on trusted computing is also becoming increasingly serious. Considering that most of the existing research is based on the static security measure, and based on the server and PC side, a security operation environment measurement framework based on mobile terminal is proposed in this paper to alleviate the information...
With the rapid development of the Internet, especially in recent years, the development of mobile Internet is increasingly rapid. Message push, which is an important way for mobile client to publish information and make communication, plays a significant role in mobile Internet. MQTT protocol is one of the implementation technologies of message push in Android system with low power consumption and...
Nutrition is an important factor in the prevention and treatment of many diseases. Nutrition is a key factor for obesity, which is a risk factor for cardio-vascular diseases, type-2 diabetes and even cancer. Many non-communicable diseases require patients to keep track of nutrition accurately. Diabetes type-2 and type-1 require tracking carbohydrate intake accurately. However, keeping track and even...
Most existing libraries use floor plans and call numbers in order to locate books rather than providing truly user's awareness of the extensive collections and services for students in the library context. With a collection of more than 48,568 volumes at the Engineering and Exact Sciences library of the Universidad Autónoma de Yucatán (UADY), the task of looking for a book can be really a time-consuming...
The measurement of consumption of public services such as drinking water and electric energy, and information management is one of the problems facing intelligent cities. In this article we describe the design of a computer system that allows the management and administration of consumption records made by smart meters that communicate through MQTT using mobile telecommunications networks. The results...
In this paper, we performed human moving pattern recognition using communication quality: cellular download throughputs, Received Signal Strength Indicators (RSSIs) and cellular base station IDs. We apply three machine learning algorithms, such as Support Vector Machine (SVM), K-Nearest Neighbor (KNN) and Random Forest (RF) and evaluate recognition accuracy of human moving patterns. Results conclude...
With the progress of the network and technology, the perfect combination of mobile intelligent terminal and internet, people are increasingly dependent on intelligent terminals. So, it was very necessary of a model for assessing the security performance of mobile intelligent terminals, especially to establish the objective model of the security performance of mobile intelligent terminal. In this paper,...
With the advancements in mobile sensors and health-care technologies, mobile health (mHealth) services are growing in demand. However, the deployment of mHealth's applications in rural and underdeveloped areas remains a major challenge, despite the investments made, largely due to unreliable communication infrastructures. In this paper, we propose delivering mHealth data in a highly disruptive wireless...
The number of elderly people over 60-year old is expected to reach 2 billion by 2050. With age people experience cognitive decline. While exercises are known to help, one of the age-associated issues is non-adherence. With the increasing adoption of technology by elderly, mobile devices become a good channel to deliver a persuasive solution. In this paper, we discuss the design and evaluation of Adherence...
In this paper, we propose a new algorithm based on the combination of the well-known Kalman Filter (KF) and a Temporal Differencing (TD) method named the Q-learning technique. The purpose is to solve a single maneuvering target tracking problem. The algorithm consists of adapting the noise process of the Kalman filter when the target changes its mode using Q-learning based decision. After a comparison...
In this paper, we propose a Mobile Crowd Sensing application based on Community Information-Centric Networking to collect opportunistic sensing data in limited area where it restricts radius of Bluetooth Low Energy beacon. The application has more valuable features by comparing with common Mobile Crowd Sensing one. First is to support data integrity and utilize simple communication model according...
This paper presents an obstacle detection system able to permit the visually impaired user to get information on the surrounding complex environment. The system also allows setting an active mobile connection with the distant assistant guide. A low-cost ultrasound microcontroller based system, capable of detecting grounded or raised obstacles up to a few meters in front of the subject, is proposed...
When a user receives a phone call, his mobile phone will normally ring or vibrate immediately regardless of whether the user is available to answer the call or not, which could be disruptive to his ongoing tasks or social situation. Mobile call management systems are a type of mobile applications for coping with the problem of mobile interruption. They aim to reduce mobile interruption through effective...
Since one GRS used for Control and Non-Payload Communication (CNPC) of Unmanned Aerial Vehicle (UAV) cannot support all operational ranges of an UAV, the handover technology of CNPC is essential to operate an UAV in a wide range. However, the CNPC physical layer standard of Radio Technical Commission for Aeronautics (RTCA) does not have a reference signal for measuring the signal strength of a neighboring...
Indoor localization system is an important topic in the wireless navigation system. Many technologies, such as Wi-Fi, Bluetooth, and ZigBee, have been developed for the indoor localization system; however, these systems still demonstrate poor accuracy and performance. The indoor localization system using Wi-Fi signals is the best option for indoor localization because most of the buildings are covered...
The goal of this paper is to describe the motivation, process and results of converting a traditional mobile robotics classroom into a flipped one. Mobile robotics has been taught at this university for 10 years and the course has proven to be very successful. The challenge with this success is that there is only one instructor, one section, once per year with an enrollment cap of 24 students. These...
