Many software development organizations strive to enhance the productivity of their developers. All too often, efforts aimed at improving developer productivity are undertaken without knowledge about how developers spend their time at work and how it influences their own perception of productivity. To fill in this gap, we deployed a monitoring application at 20 computers of professional software developers...
With the rapid development of cloud computing, thousands of servers and various cloud applications are involved in data center. These changes result in more and more complex flows in data center, which motivates the need for faster, lower overhead, more scalable large flow detection technology. This paper firstly shows the shortcomings of the traditional large flow detection technologies. Then it...
Smart home is a house that uses Internet of Things(IoT) to monitor the environment, control the electric appliances and communicate with the outer world. Smart home is a complex technology, but a developing one. A smart home automation system has been developed primarily because in today's time and world, everybody's in a surge and wishes to screen and get to everything without being there physically...
The traditional auto-reclosing method in relaying cannot meet the requirements of the distribution network with small hydropower in case of faults. In order to provide reliable guarantee for safe operation of transmission line, on the basis of the improvement measures by the reclosing device in the practical engineering, a reclosing device adapted to synchronization line of small hydropower station...
A continuous real-time data acquisition and communication equipment based on Advanced RISC Machine and Field Programmable Gate Array is designed and developed, on the basis of which an on-line monitoring and fault diagnosis system for high voltage circuit breaker is realized. Mechanical, electrical and environmental parameters of the switching process can be gathered by this system. The function modules...
While autonomy developers have been able to take advantage of external control interfaces on intelligent vehicles for years, they have typically had to choose between control architectures and interfaces that only allowed them to use the existing behaviors of the vehicle (task-level control) or those that allowed them to set desired control values (setpoint control) but then required them to re-invent...
Multi-display environments (MDE) are replacing single-display environments (SDE) to increase productivity of users. Although, little research of MDEs was conducted in domains of limited use of computer system. One such domain is pharmacy, in which computer systems are used by pharmacists to effect payment, search for medicines and offering services to patients. In this preliminary study we conducted...
The paper describes a software application running on Android mobile devices, used to help the neuromotor disabled patients to communicate with the clinicians or caretakers. The proposed application also include a telemonitoring (remote monitoring) component used to collect and process few physiological parameters of the patient. The application is part of a more complex communication and monitoring...
Open Flow, an essential technology in Network functions virtualization (NFV) implementation, enables software-dened networking (SDN) to develop from a simple concept and divides traditional switch into two parts: a data plane and a control plane. Because software-dened rules are used to control traffic, the concept of NFV was developed. Numerous virtualization studies on NFV have investigated conventional...
The research introduces the network to monitor the environment on campus, under the existing distributed network architecture requirements are not easy to achieve. We propose a set of OpenFlow technology using SDN detect network attacks and network cameras and surveillance systems combining wireless sensors and artificial intelligence techniques supplemented purpose of this study for OpenFlow simulation...
The paper considers functions of the informational technologies which are implemented in the modern systems for monitoring complex industrial facilities. It substantiates the task to develop systems for monitoring technical state of the electrical equipment of the rolling mill units. The hardware configuration and software of the monitoring system are proven to be determined by technical parameters...
This paper focuses on ARP attacks in switched networks, from ARP protocol perspective, analyses the principle of ARP attacks and the exceptional interrupt occurs they cause when the terminal users access the servers. To quickly and effectively detect ARP spoofing, this paper proposes a WinP cap based detection system of ARP spoofing. Using Win Pcap driver development monitoring software, implements...
High voltage circuit breaker (HVCB) is a sort of important control and protection equipment in the power system. An on-line monitoring system for HVCB is designed and developed to improve the stability and reliability of power system. It can collect and save useful data when HVCB is running, gain electrical and mechanical characteristic parameters and provide effective conclusion of fault diagnoses...
In recent years, along with the continuously expanded application fields of RFID, the system capability has been put into a higher level, and at the same time, the research of 2.4GHz active RFID system has attracted more and more attention. In this paper, the basic tag function and the partial hardware structure based on the low power 2.4GHz radio transceiver chip nRF24LE1 are introduced briefly....
Ethernet is currently being discussed within the automotive community to become a general network technology for interconnecting future distributed automotive systems. If this is the case, a complete tool chain will be necessary to support developers to implement their functions. One important component is the availability of tools to monitor, generate, manipulate, and simulate traffic in distributed...
Teleoperation is an important strategy for controlling outdoor mobile robots. It determines the reliability and the fields of the mobile robots. This paper introduced a type of teleoperation system for multiple mobile robots. Improved image radio system ensured the image transmission channels of coherent image clarity. Improved new data transmission system ensured that the data transmission is stable...
The paper focuses on a type of generator sets, designing a generator set's monitoring detecting system, prototype circuit is designed, the serial communication between the MCU (Microcontroller Unit) and the PC (Personal Computer) is achieved, the anti jamming technology has been considered, and it uses VB (Visual Basic) to carry out the design of the background manager, the whole system is debugged.
It is a key technique and a trend in ship automation development to marine engine room simulator. The available products used for monitoring and control usually consist of many distributed microcomputer units and one management personal computer. The functions are performed not on an upper layer monitoring and control in a computer network but in an independent personal computer. To overcome the disadvantage...
This paper introduces a wireless medical liquid-level monitoring and controlling system based on RF technology, in which liquid levels beyond limits are monitored by using the principle of different refractive indexes of light rays in air and in liquid and adopting the non-contact photoelectric monitoring method, and 8051 single chip computer were used as main MCU, through controlling RF module RF905...
The existing data sampling schemes can not update ROM serial numbers of DS18B20 automatically and locate DS18B20s accurately. For these reasons above, it is difficult to replace the faulty DS18B20s immediately. To solve this problem, both I/O (Input/Output) ports number of MCU (Micro Controller Unit) and the value of temperature alarm trigger registers (TH and TL) are used to determine the storage...
