In this paper, we investigate the possibility of spectral coexistence of the two services through the analysis of interference potential between IMT-2020 and fixed-satellite service (FSS) uplink in the 27-27.5 GHz frequency band. We model and calculate the interference power at victim receivers referring to up-to-date ITU-R documents and compare them with the protection criteria of the victim receivers. Furthermore, three-dimensional (3D) topographic data with latitude/longitude/altitude coordinates are adopted to exactly model the interference power aggregated from a large number of terrestrial IMT-2020 systems in worldwide areas. The results show that the FSS space station is safe from the aggregated IMT-2020 interference, and the IMT-2020 service can be protected when base station (BS) and user equipment (UE) are located 3.3 and 0.9 km away from the FSS earth station.

The variety of vehicle manufacturers and vehi-cles makes it difficult to configure the vehicle management system. For the problem, this paper proposes a method that the vehicle itself registers the management items to the external management system and the policies for accessing the items are automatically created and managed by the system. To show the feasibility, the access control examples will be represented.

This paper presents an activity recognition using smartphone built-in accelerometer. One of the most important issues in implementing activity recognition on embedded systems, including smartphones, is to achieve a high accuracy with a low computational cost and low memory usage. In this paper, we propose an activity recognition using the fully convolutional networks and introduce a new method to generate an input signal image using the combination of deep features and orientation-independent features. The experimental results show that the proposed method is able to achieve a high accuracy with a low memory usage.

In this paper we introduce the conceptual design of vehicular digital cockpit that adaptively changes contents of the voice guidance and the digital cluster according to the driver ’s age, gender and driving experience. Based on this conceptual design, we propose the necessary functional requirements to realize driver-adaptive human machine interface. In order to complete the digital cockpit adapted to the driver, it is necessary to measure and learn about the driver’s condition, driving ability, and the cognitive response to the human machine interfaces as well as adapting to driver’s preference and characteristics.

In this paper, we propose a new hybrid ARQ error control scheme for the data communication system with multiple parallel channels. The receiver is supposed to have some fixed size of buffers (called resequecing buffer) which are used to temporarily store the packets that are correctly received out of sequence. The hybrid ARQ scheme is a combination of Go-Back-N ARQ and Selective-Repeat ARQ protocols. The system operates under the SR-ARQ protocol while there are still some available buffers for the upcoming packets at the receiver. Reversely, the system operates under the Go-Back-N ARQ protocol when the resequencing buffers are totally occupied by the packets which are received out of sequence. We describe the detailed operations of the presented hybrid ARQ scheme and evaluate the system performance (mainly throughput efficiency) under the assumption that the system has two or three different channels. We show the influences of various features on the throughput efficiency and illustrate it at different conditions, such as the number of channels, delay of channels etc. Based on the results of computer simulation, it is clear that throughput efficiency would be reduced by unduly using multiple channels at certain conditions, and introducing buffers at receiver is extremely efficacious as the way to deal with the problem.

With the explosive growth of mobile data traffic, the number of 4G LTE access network equipment has also increased sharply. This led to a direct increase in operating costs in terms of mobile telecommunication service providers. In this process, the operation method that minimizes the power consumption of the mobile network equipment while keeping the user’s service experience at the highest level is examined, and the PSi & PSo algorithm that can realize this is discovered and verified in the commercial network. With this, it will be possible to meet both the power saving and the service experience when it is adjusted according to the traffic level. In addition, we anticipate that the effects will be even greater in the upcoming 5G era.

WLAN-based positioning methods are popular because they can be deployed anywhere without additional infrastructure investment. Among them, positioning based on fingerprint radiomap has been widely studied in terms of fingerprint radiomap construction and device position estimation in offline (training) and online (positioning) phase, respectively. This paper presents simple and practical WLAN-based positioning method in which WLAN access point (AP) location database is considered as a radiomap to reduce its size and radiomap is updated in unsupervised manner in online (positioning) phase to maintain up-to-date without additional construction cost. Experiments carried out in smartphone device and shows effectiveness of the proposed methods.

This paper presents a methodology for analyzing spectral efficiency based on dataset measured from real-field. The measurement dataset consists of downlink control information and reference signal received power of Long-Term Evolution signal which is transmitted by live base station. This paper also introduces a way of collecting data and providing analysis results of a selected cell through statistical investigation. These statistical data and measurements allow realistic predictions of network efficiency because they reflect current cell characteristics. The spectral efficiency is analyzed to be 1.72 for an example cell and expected to improve to 2.22 on average depending on the conditions.

The widespread use of information and communications technologies enhanced urban infrastructure, thus enabling the emergence of smart cities. Among these technologies, drones can be useful to generate high-resolution 3D urban models to provide detailed information about the smart city structure. However, successfully using drones for 3D modeling of wide areas is challenging mainly because of their limited resources such as battery autonomy, onboard memory, and processing. Therefore, trajectory planning can improve resource utilization by reducing the search space during drone flight for modeling. We propose a comprehensive framework based on the geographic information system for drone trajectory planning. Compared to previous studies, we simultaneously apply trajectory and 3D modeling constraints using flight map information including visibility, wind and risk. We verify the effectiveness of the proposed approach on datasets from the South Korea Open Data.

The rapid growth of information and communication technologies has put companies under the pressure of continuously improving their business processes to be able to maintain their position in a highly competitive environment. For this purpose, process mining has recently emerged to analyze the behavior of organizations through the extraction of process related knowledge from the event data recorded in today’s information systems such as Supply Chain Management System, Workflow Management System, Enterprise Resource Planning, Customer Relationship Management System, etc. This paper presents an industrial application of process mining in a real purchasing process of a heavy manufacturing industry. The event data of this process are extracted from the Shipbuilding Processing Plan Management System of the company, filtered and analyzed using process mining techniques. The findings of the analysis can be used by the company to optimize and improve their processes.
