Rectenna system design

The function of the rectenna in the solar power satellite system is described and the basic design choices based on the desired microwave field concentration and ground clearance requirements are given. One important area of concern, from the EMI point of view, harmonic reradiation and scattering from the rectenna is also designed. An optimization of a rectenna system design to minimize costs was performed. The rectenna cost breakdown for a 56 w installation is given as an example

Scheduling Information System Design and Monitoring College Lecturer in Jakarta STMIK

Scheduling classes and professors monitoring plays a very important for the continuity lecturesat a university. Scheduling and monitoring STMIK Jakarta not use computer functions optimally,because there are still many weaknesses, among others, information about subjects that havebeen issued are still done manually, so that can happen subjects who had been in out in out again.This thesis tries to provide a solution Scheduling Information System Design and MonitoringLecture Lecturer, hoping to overcome existing weaknesses and the information obtained can bemore quickly and accurately

Administrative System Design Applications Hospital Patients in Hospitals Sari Asih Using the Language Programming Microsoft Visual Basic 6.0

In essence the hospital during this asih Mampang Depok administration in patientsreceiving inpatient care is still done manually so often cause errors in the delay ofpatient care information.Based on these problems, I am interested to try to help resolve the problem bycreating a computerized system and the author will use the display programanmicrosoft Visual Basic 6.0

Rectenna System Design

The fundamental processes involved in the operation of the rectenna system designed for the solar power satellite system are described. The basic design choices are presented based on the desired microwave rf field concentration prior to rectification and based on the ground clearance requirements for the rectenna structure. A nonconcentrating inclined planar panel with a 2 meter minimum clearance configuration is selected as a representative of the typical rectenna

Orbital Maneuvering system design evolution

Preliminary design considerations and changes made in the baseline space shuttle orbital maneuvering system (OMS) to reduce cost and weight are detailed. The definition of initial subsystem requirements, trade studies, and design approaches are considered. Design features of the engine, its injector, combustion chamber, nozzle extension and bipropellant valve are illustrated and discussed. The current OMS consists of two identical pods that use nitrogen tetroxide (NTO) and monomethylhydrazine (MMH) propellants to provide 1000 ft/sec of delta velocity for a payload of 65,000 pounds. Major systems are pressurant gas storage and control, propellant storage supply and quantity measurement, and the rocket engine, which includes a bipropellant valve, an injector/thrust chamber, and a nozzle. The subsystem provides orbit insertion, circularization, and on orbit and deorbit capability for the shuttle orbiter

Information System Design in the Yamaha Music School

The design of Information Systems was written because this now requires speed and accuracy of the information needed by someone to assist their daily work. In this thesis, the writer tries to design a system to manage the company to facilitate the work performed by regular employees, both in terms of administration, education, until the preparation of reports to the CEO. In this system, also described the differences between the old system with a new system so it can be seen how quickly the new system

Data Processing System Design Information Students School Cost and Data on Al-husna Kindergaten Using Microsoft Visual Basic 6.0

This writing explains the data processing system of student tuition and data on Al -Husna Kindergaten that during this process is still done manually, so much thepossibility of error. Therefore, the authors provide a better alternative to create a dataprocessing system of student tuition and a computerized data by using Visual Basic6.0 programming language, the authors propose to help students process dataprocessing, data school cost

Microflow valve control system design

A design synthesis for a microflow control system is presented based on the interrogation of an analytical model, testing, and observation. The key issues relating to controlling a microflow using a variable geometry flow channel are explored through the implementation and testing of open and closed-loop control systems. The reliance of closed-loop systems on accurate flow measurement and the need for an open-loop strategy are covered. A valve and control system capable of accurately controlling flowrates between 0.09 and 400 ml/h and with a range of 900:1 is demonstrated
