Now a days chaotic systems have an important role in secure communication and cryptography. As FPGA implementation have certain advantages over analog one, different chaotic system like chaotic oscillator, True random number generators and chaotic systems used in image processing, optical circuits for secure communications were successfully realized in FPGA. This paper presents FPGA implementation of Autonomous Pandey-Baghel-Singh chaotic signal generators using RK 4 algorithm. Numerical solution of Differential equation system is obtained and coded in Verilog and tested withXilinx vivado 17.3 design suite in Artix-7 Nexus 4 DDR and Basys 3. Performance of the FPGA based chaotic generators is analyzed using 106 data sets with the maximum operating frequency achieved up to 359.71MHz.

Keywords: Chaotic Generators, RK 4 algorithm, FPGA.

Rocker bogie finds a vital role in determining the scientific analysis of objectives separated by many distance apart. The mobility design at present is quite a bit complex with many legs or wheels. The wheeled rover which is capable of driving over the rough terrain provided with high degree of mobility suspension system.The drive provided by the rocker bogie is simple and it mainly operated by the means of two motors.The motors are kept inside in order to make it more reliable and efficient.In overcoming the bumps in the natural terrain the wheels are operated simultaneously.By implementing this mechanism the vehicle can come through any obstacles it faces during the travel in the terrain.We have tested it by conducting a series of mobility experiments on agricultureland,rough roads,inclined,stairsandobstaclessurfaces and concluded that it is possible to implement. This project mainly focuses how the mechanism finds its place in the wheel chair.

Significant internet penetration in Indonesia makes internet providers in Indonesia to compete, to win the Market. PT. X as one of Internet Provider in Indonesia has significantly transformed to anticipate the business dynamics. One of the main program is to focus in Small-Medium-Enteprise (SMEs) segment with Wifi Station service. Nevertheless, Wifi Station has problem that is in its long provisiong process thus causing many outstanding orders that have not been installed. as many as 69% of work orders are installed more than 14 days which means over standard time specified. This long provisioning process may cause customers to switch to competitors. Based on this problem, indicated that there is a waste process in Wifi Station provisioning. This research uses lean service concept with improvement network through Define-Measure-Analyze-Improve-Control (DMAIC). The tools used in this research are Value Stream Mapping (VSM), Process Activity Mapping (PAM), Borda Count Method (BCM), Root Cause Analyze (RCA), and risk management approach. Based on analysis, occured that high level of main waste caused by Duplication, Lack of Standardization and Delay.

Sub-contractor presence played an important part in the project success delivery of main contractors. Sub-contractor's work performance is often considered better than that of internal workforces. This fact was driving company's policy to handover bigger part of primary business process to sub-contractors. On the other hand, when subcontractor withdrew from the projects, meanwhile critical business parts were being handled by them, it would become very detrimental to the projects. This research will study further by analyzing variables based on construction projects. The variables are quality, time, cost, added by technical variables such as project execution and project management. This studyused primary data which have been collected using questionnaire method. The respondents of questionnaire are fabrication services, assembly and assembly trial subcontractor's chief executive. Results of thisworkhad revealed the most critical variables on this case about relationof the main contractor and service sub-contractor company. Improvement suggestions were given in orderto maintain work relationship with the current and any future subcontractors who will be working together with X Ltd.

In spite of more advantages in information security, cybercrime has increased proportionately. Cybercrime is an illegal activity where a computer is used as a tool or target or both. Perpetrator takes any one of these activities for obtaining secured information from other systems. Ethical applications are available in the cyberspace like face book, twitter, and instant message etc. Devices are connected together in cyberspace to converse and share information using TCP/IP protocols. When such a way communication happens, perpetrator with current technology is prying secured information of others. To overcome the problems, nowadays biometric principles are used to secure information. Even though the approach of securing information by biometric is thought complicated, information are hacked without the knowledge of authorized person. This paper illustrates an overview of cybercrime; attacks of cybercrime in biometric and solutions to secure data from the cybercrime.

Remote sensing is the effective and efficient field in the digital world. Global usage of application with the help of remote sensing is increasing consecutively. Remote sensing applications help to spy enemy satellite in warfare, Tsunami prediction, Global warming detection, Forest Monitoring and Water management. Satellite image classification helps to agriculture assessment, Sea level prediction, Weather forecasting and Soil moisturize. Basically, Classification methods come under Supervised, Unsupervised and Object based analysis method. These methods are selected based on the satellite imagery type. Imagery type categorized based on the sensor which is used to take the earth imagery from the satellite. There is a huge number of satellites takes the earth image from space. Countries are highly focused on technological advancement and are actively engaged in ensuring the growth and security of the country through satellite. This paper helps to analyze the current satellites behavior and its applications. Satellite sensor and sensor characterization also discussed in the technological aspect.
