In order to realize a system of multi-channel telemetry signal transmitter and receiver module, a design for generating encryption and decryption processing signals in the transmitting module and the receiving module is proposed on the baseband signal processing hardware platform. For the generation of the single-bit telemetry control signal, the idea of using dual-port RAM sequential logic and combinational logic circuits is adopted in the FPGA module, and sorting processing is performed in the DSP module. Combined with embedded system and software radio design, the software design based on C programming language and QUTUS II system simulation are given. The design has passed the hardware and software joint debugging, and can pull up the single-bit telemetry control signal corresponding to the position of the data stream in the case of up to 300 key contents for encryption and decryption processing.

Data clustering has been received considerable attention in many applications, such as data mining, document retrieval, image segmentation and pattern classificationThe enlarging volumes of information emerging by the progress of technology, makes clustering of very large scale of data a challenging taskIn order to deal with the problem, more researchers try to design efficient parallel clustering algorithmsIn this paper, we propose a parallel DBSCAN clustering algorithm based on Hadoop, which is a simple yet powerful parallel programming platformThe experimental results demonstrate that the proposed algorithm can scale well and efficiently process large datasets on commodity hardware.

In recent years, China's economy has developed at a high speed, and the resulting air pollution has become more and more serious. The human health problems caused by this are worrying. To this end, the air quality monitoring system of wireless sensors is designed to realize the functions of networking, air pollution data collection and transmission, and user terminal display. The monitoring part adopts the wireless sensor network, and the monitoring center adopts the C# programming language design in the VB environment. The monitoring software is based on the Web network technology, and the corresponding density value collected by the relevant sensor nodes can be queried by opening the corresponding webpage through the browser;The data collected by the node is stored and exported, and the node data is exported and printed according to requirements. It has the advantages of real-time, low power consumption and low cost, and has certain practical value in air pollution monitoring.

Assembly Language andprogramming is a course highly depending on practice. Practice teaching is an aid for teacher's classroom teaching. Aiming at the limitation of the practice teaching, a network platform of experiment for Assembly Language andprogramming is designed. Via this platform, students can do experiments anytime and anywhere after class, which effectively extends the regular practice teaching. The questions encountered by students during their experiments are answered timely. The communication between the teacher and students has been enhanced. The enthusiasm of students' programming has been stimulated. The teaching effectiveness has been noticeably improved.

In India, many historical documents are preserved where handwritten Devnagari script has been used. With the advancement of time, the handwritten documents is in deforming styles and shapes. The handwritten OCR software that can transform this task with different accuracy rate. In 2015, this work was done for the printed character and provided the accuracy rate for Devanagari numerals of 89% with 4.5% of confusion rate whereas the recognition rate for English set was 78.4% with 18% of confusion rate. Although many work has been done towards HOCR but accuracy rate is 94% to 97%. My research work will be towards the transformation of handwritten Devanagari script into editable word form by using Convolutional Neural Network. For choosing this area for my research is because transformation of handwritten ancient characters is important as many important historical documents like manuscripts into machine editable form which can be easily preserved and accessed. With the help of strong and powerful dataset and combination of different neural network techniques, the accuracy rate can be increased and we can be able to preserve more historical documents for our access.

Agile methods advocating early and frequent delivery, incremental and iterative development, and adaptive planning gradually becomes a popular software development methodology around the world. Many top software companies adopt agile methods and develop lots of remarkable software products. Although many researchers have studied agile methods using various approaches, whether and how agile methods help developers establish better software is still controversial. In this paper, we study the business data, development, and human resources records provided by Titansoft, a Singapore IT service corporation which is well-known in its successful Agile experiences. From analysis of the data, three primary impacts brought by agile adoption are revealed: (1) A temporary business stagnation; (2) Improvement in product quality; (3) Positive evolution in corporate culture. To the best of our knowledge, this paper is one of the few studies discussing how agile methods influence a software company in software development, business, and corporate culture aspects throughout a relatively long duration (more than 5 years).

Smart grid components are free and secure for exchanging data that requires a good data communication network to support, the next generation of Internet technology applications become an inevitable trend. Internet Protocol Version 6 as the core of the next generation of Internet construction, with its own advantages to promote the development of smart grid information. In view of the complexity of the future power grid business, the traditional routing mechanism load serious problems, The article proposes SDN technology to design a Qo S management system which can allocate and allocate network traffic to the underlying terminal network, And then use the border router to the priority of each terminal sort and send the results to the core router, to achieve the highest transmission efficiency of each terminal Qo S, making the power communication network service quality improvement. At last, this paper tests the SDN programming interface of the video data transmission service of the smart grid, and the boundary router Qo S management system simulation.

Fast growing of uncertain renewable energy sources (RES) in power system results difficult to control reactive power. The purpose of optimal reactive power dispatch (ORPD) is to find the appropriate values of PV bus voltages, transformer tapings and shunt var compensation. For the solution to ORPD two conflicting objective functions, active power loss and voltage deviation are minimized simultaneously. Because of the stochastic behavior of wind and solar power generation, appropriate probability distribution functions are considered to model them with Monte-Carlo simulation technique. Solution to multi-objective ORPD (MO-ORPD) problem, NSGA-II along with constraint technique is proposed. Furthermore, IEEE standard 30-bus system is adopted to find the superiority and effectiveness of NSGA-II. Two study cases such as deterministic and stochastic (scenario-based) are considered to analyze the simulation results. The obtained simulation results show that the proposed algorithm has the ability to find the global optimal solution in all the scenarios.
