為了有效地提升鉛酸蓄電池的使用壽命，同時實現對充電過程的監控，設計出一種用單片機控制的36 V鉛酸蓄電池充電電源。本電路采用反激式拓撲，連續電流工作模式，電源管理IC設計在電源的副邊，由ELAN公司的EM78P258N單片機模擬，是用可編程器件模擬電源管理IC，實現智能電源低成本化的一次成功嘗試，通過對單片機的軟件設計實現了充電電源的狀態顯示、充電時間控制、報警、過溫保護、過壓保護、過流保護等功能。本充電器真正的實現了鉛酸蓄電池的三段式充電過程，其最高輸出功率可達90 W，效率約85%，成本不到20元，具有很高的市場競爭力。 Abstract: In order to extend the life of lead-acid battery efficiently and supervise the charging process meanwhile， a 36V lead-acid battery charge powe supply controlled by microcontroller is designed. The charger is flyback switching power supply and works in CCM mode. A EM78P258N microcontroller made by ELAN microelectronics corporation is used as power management IC which is designed at the secondary circuit. The project is a successful attempt to low-cost intelligent power used microcontroller simulating power management IC. The charger also has the functions of the status reveal， charge time control， alarming， thermal protect， current limit and overvoltage protect by the software design. The circuit actually implements the three-step charge process， whose power is up to 90W and whose efficiency can get 85%. The net cost of this charger is less than 20 RMB， so that the charger is of powerful market competitiveness.

In this document, the term Ô60xÕ is used to denote a 32-bit microprocessor from the PowerPC architecture family that conforms to the bus interface of the PowerPC 601ª, PowerPC 603ª, or PowerPC 604 microprocessors. Note that this does not include the PowerPC 602ª microprocessor which has a multiplexed address/data bus. 60x processors implement the PowerPC architecture as it is speciÞed for 32-bit addressing, which provides 32-bit effective (logical) addresses, integer data types of 8, 16, and 32 bits,and ßoating-point data types of 32 and 64 bits (single-precision and double-precision).1.1 Overview The MPC106 provides an integrated high-bandwidth, high-performance, TTL-compatible interface between a 60x processor, a secondary (L2) cache or additional (up to four total) 60x processors, the PCI bus,and main memory. This section provides a block diagram showing the major functional units of the 106 and describes brießy how those units interact.Figure 1 shows the major functional units within the 106. Note that this is a conceptual block diagram intended to show the basic features rather than an attempt to show how these features are physically implemented on the device.

This book evolved over the past ten years from a set of lecture notes developed while teaching the undergraduate Algorithms course at Berkeley and U.C. San Diego. Our way of teaching this course evolved tremendously over these years in a number of directions, partly to address our students' background (undeveloped formal skills outside of programming), and partly to reect the maturing of the eld in general, as we have come to see it. The notes increasingly crystallized into a narrative, and we progressively structured the course to emphasize the ?story line? implicit in the progression of the material. As a result, the topics were carefully selected and clustered. No attempt was made to be encyclopedic, and this freed us to include topics traditionally de-emphasized or omitted from most Algorithms books.

This document is designed to aid anyone considering whether to write an emulator for an arcade game machine. It will attempt to answer frequently asked questions, give a step by step tutorial, and provide the resources necessary for a capable programmer to begin work on an emulator for an arcade game.

This Handbook, published under the auspices of the Senior NATO Logisticians’ Conference (SNLC), i s i ntended as a simple guide to logistics i n NATO. It does not attempt to examine current i ssues or provide answers to the problems that logisticians will face, but i t rather aims at i ntroducing them to some of the basic principles, policies, concepts and organisations with which they will work.

jsp和xml。XML and JSP are two important tools available in producing a web application. This chapter examines the potential of mixing these two technologies in order to enhance the capabilities of JSP. While this chapter will cover many things about XML, this chapter will not attempt to teach XML. Instead it focuses on how JSP and XML can be used together as a highly flexible and powerful tool. In general the usage of XML in these examples will be kept simple and should cause no problems for users who are starting XML.

CCE is a multi-instance learning method solving multi-instance problems through adapting multi-instance representation to single-instance algorithms, which is quite different from existing multi-instance learning algorithms which attempt to adapt single-instance algorithms to multi-instance representation
