Dynamical Casimir Effect for a Swinging Cavity

The resonant scalar particle generation for a swinging cavity resonator in the Casimir vacuum is examined. It is shown that the number of particles grows exponentially when the cavity rotates at some specific external frequency.Comment: to appear in J. Phys. A: Math. Theo

Application of Learning Child Child Using Macromedia Flash Mx.

The development of information technology on computer education causes more and more important, especially in children. Currently children are expected to be familiar with computers from an early age. The appearance of interactive multimedia technology capable of presenting text, images, animations and video simultaneously or bergantiian. Children are increasingly familiar with the computer and make children more familiar with computers. Multimedia applications which presents images such as for example in the form of animated Flash MX can provide or can produce an interactive application

Customer Service Application in the Motor Court Garage Using Visual Basic 6.0

Along with the rapid development era, the more permsalahan facing mankind. The necessity to solve problems quickly, accurately, and efficiently, it is very necessary. Therefore the role of the computer provides an enormous impact on human life, as a means to accelerate data processing. In this study, the authors make a computerized system to process customer service at Palace Motor Repair using Microsoft Visual Basic 6.0. This system aims to replace the manual systems with new systems that have been computerized, with the hope that this new system can facilitate data processing on the Motor Palace workshops. Scientific writing is also equipped with Flow of Document (FOD), Data Flow Diagrams (DFD), Entity Relationship Diagram (ERD) and also the normalization of the application

All-Pass Sections with High Gain Opportunity

In this paper, two new circuits for realizing firstorder voltage-mode (VM) all-pass section (APS) with variable gain are presented. The first proposed filter uses a single differential difference current conveyor (DDCC), one grounded capacitor and three resistors. The second proposed filter consists of two DDCCs, three grounded resistors and one grounded capacitor. It provides highinput and low-output impedances and can provide high gain. Both of the proposed circuits do not require any element matching condition. Moreover, oscillator circuits with minimum number of active and passive elements are derived from the proposed APSs. The proposed circuits are tested experimentally or by simulation using SPICE program to confirm the theory

Lossy/Lossless Floating/Grounded Inductance Simulation Using One DDCC

In this work, we present new topologies for realizing one lossless grounded inductor and two floating, one lossless and one lossy, inductors employing a single differential difference current conveyor (DDCC) and a minimum number of passive components, two resistors, and one grounded capacitor. The floating inductors are based on ordinary dual-output differential difference current conveyor (DO-DDCC) while the grounded lossless inductor is based one a modified dual-output differential difference current conveyor (MDO-DDCC). The proposed lossless floating inductor is obtained from the lossy one by employing a negative impedance converter (NIC). The non-ideality effects of the active element on the simulated inductors are investigated. To demonstrate the performance of the proposed grounded inductance simulator as an example, it is used to construct a parallel resonant circuit. SPICE simulation results are given to confirm the theoretical analysis

Sales Data Processing in Book Stores Mahasuri Using Microsoft Visual Basic 6.0

At the present time the technology has advanced with his street had taken the time tomake everything easy to grow and all can be done quickly and precisely. Moreover,with an additional tool in the form of a computer to make all that had been long donemore quickly and conveniently. Computer tools can we find anywhere, either inoffices or in shops. Like shopping in the sales transactions are still conducted bymanual count manualisasi with tools made ineffective because it can inhibit the salestransaction at the time. For example in mahasuri bookstore sales are in the system andmaking monthly reports manulisasi done, so the data required to support operationalprocesses often experience delays and will be a lot of mistakes,It needs to be made a database on the system sales of books and making its report andit need a program to run the database. So that all can be controlled either in systemsales as well as the preparation of reports for each month

Goods Delivery System Design Pt.jasa Pratama

In this study, the authors take the title "delivery system design on PT.Jasa Pratama". Where delivery is sala one of the major activities of the company. For the delivery of processing performed by data entry and to facilitate the delivery process is done with computer processing. Therefore, the authors use the programming language Visual Basic version 6.0 for the system in the company shipping the goods will be processed efficiently and improve the information produced
