The abundance of activity trackers and biosignal sensors as well as the evolution of IoT and communication technologies have considerably advanced the concept of Quantified-Self. Nowadays there are several frameworks and applications that realize the concept, focusing though strictly on specific areas, from daily use to professional activities such as sport and healthcare. This work proposes a versatile,...
Efficient design of wireless networks benefits from the exchange of control messages. However, control messageitself consumes scarce channel resources. In this paper, wepropose CoS (Communication through symbol Silence), a novel communication strategy that conveys control messages for free without consuming extra channel resources. CoS inserts silence symbols in data packets and leverages the intervals...
In recent years, mobile data gathering in wireless sensor networks has attracted much interests in the research community. However, despite extensive efforts, many of previous work in this area lies only in theory and evaluates network performance with computer simulations, which leaves a large gap from reality. In this paper, we present the design and implementation of a general purpose, flexible...
The aim of the development is a cardiograph unit that will produce daily monitoring of the patient, the processing of the data and their transmission over the wireless channel. The module detects characteristic points using digital filter unit, which can determine the state of the cardiovascular system.
In Transylvania's University — Creativity Laboratory we try to do complex trainings of students and high school children's — connected with the their preparation for LabVIEW (Laboratory Virtual Instrumentation Engineering Workbench) Academy examinations. The graphical nature of LabVIEW makes it easier to develop working code faster — quickly drag and drop built-in functions to simplify acquisition,...
IEEE 802.11 (Wi-Fi) networks' popularity has boomed in recent years and their presence is continuously increasing. More and more large-scale networks are being deployed, consisting of a large number of access points. In these networks, the handover process has proven to be very challenging. In standard Wi-Fi, the client is responsible for making the handover decision and the access point plays no...
More than forty million people in the world are epilepsy sufferers. Epilepsy is a neurological disease. That is characterized by the presence of seizures in which the patient has convulsions, among other symptoms, that can cause damage, and even lead him to death. For this reason, it is important to develop systems for allowing early detections. Additionally, the cost of this kind of devices is usually...
Multi-vehicle operations using various types of unmanned vehicles (UVs) can increase efficiency of marine data acquisition, reduce the crew risk and lower mission costs. These types of missions are very complex and often involve systems that are not interoperable. From an operational perspective however, some level of integration is necessary. Typically, a common network system architecture and Situation...
At the edge of the network with cache servers, researchers usually focused on how to cache the contents or how to deliver cached contents from edge network to user equipment (UE). In this paper, we study the content delivery scheme in ultra-dense network (UDN) scenario. Since small cells (SCs) are densely and largely deployed in UDNs, it is hard to operate the SCs with a central unit. Thus, our delivery...
The paper subject is the modernization of two mobile wood processing equipment, a debarking and a chipping machine, working at the forest border and used to obtain wood chips for the pulp and paper industry, in order to work in tandem operating mode. Control hardware has been added and original software has been elaborated but with the wireless communications between the two machines established,...
Based on research of the robot car's motion control system, TMS320f2811 chip which produced by Texas Instruments (TI) was used as the core chip of the control circuit. How to design the control circuit of robot car was illustrated in this paper from hardware part and software part. The design of motion control system for robot car based on DSP technology and integrated-separated PI control algorithm...
This paper presents some results of a research work that aims to use Brain - Computer Interfaces to facilitate rehabilitation training of a patient who has lost motor functions. The subject must perform motor imagery tasks that will be transmitted to a computer application. The paper is also focused on the study of classification algorithms that can be optimal candidates for signals classification...
Since the effective and efficient system of water quality monitoring (WQM) are critical implementation for the issue of polluted water globally, with increasing in the development of Wireless Sensor Network (WSN) technology in the Internet of Things (IoT) environment, real time water quality monitoring is remotely monitored by means of real-time data acquisition, transmission and processing. This...
In order to optimize the customers' dining experience and promote the efficiency of the waiters and the managers, an economical wireless ordering system with touch screens based on Bluetooth technology is designed for the restaurants. The Single-chip Microprocessor (SCM) MSP430F149 is employed to form the minimum system. A TFT touch screen with a memory card is used for the customers to order dishes...
This paper proposes a dynamic channel utilization method to minimize transmission delay by considering radio interference and wireless link rate for software defined multi-channel wireless mesh networks (SD-WMN). The OpenFlow technology, which enables us to control flows by programming, is employed to effectively utilize multiple channels in SD-WMN for traffic balancing. Existing methods assume fixed...
Electronic control units (ECUs) of in-vehicle systems are being designed to handle an increasing number of functions. However, malfunctions may occur when an in-vehicle system is upgraded. Moreover, because they are visible to hackers, connected vehicles are becoming the object of cyberattacks. Therefore, the necessity of updating ECU software is increasing. Car owners cannot use their cars during...
Automatic composition design software for human body equivalent phantoms has enabled engineers to increase the efficiency of phantom fabrication. While our previously reported preliminary version of phantom composition design software is effective for phantoms with relative permittivity and conductivity exceeding 40 and 5 S/m, respectively, the software is fundamentally difficult to apply to phantoms,...

A noise removal ECG signal provides certain details about the electrical activity of the heart. The main focus of this paper is to identify the suitable filtering method for ECG signal noise removal for physiological parameter measurement and monitoring using TCP/IP Protocol. Feature extraction...
In today's world, wireless communication became the master use in any technology that need transferring of data between devices in far distant places. The problems of paratrooper when they reach the land they are scattered and can't find each other's position quickly. Sometimes paratroops don't find their equipment that is thrown from the plane to the ground. The main objective of this study is to...
