许多项目管理者,在根本不可能完成的最后期限下苦苦挣扎。系统交付后,又花许多时间去维护该系统。原因:项目管理太弱。 3.1管理的范围 有效的项目管理集中于3个P上:人员( People)、问题(Problem)和过程(Process)。其中人员是第一位的。软件工程是人的智力密集的劳动,忽视了这一点就不可能成功?

Suppose that two aerial routes--one Eastbound and one Northbound--cross at an altitude of 35,000 feet at junction(Figure 1). In the absence of air-traffic control, the times at which eastbound planes would arrive at the junction would reflect a Poisson process with parameter(per minute)

Explain or explore something, (e. g, process of make a machine, the causes of a natural or ocial phenomenon, the planning of a project, or a solution of a problem) Description mainly deal with appearance and feelings, and narration with events and experiences, unlike the two, the exposition mainly deals with relationships as well as processes

Oxidize the ditch craft in dirty water handle of application and development Summary: This text expatiated primarily the Carrousel oxidizes the construction craft mechanism of the ditch and circulate the problem exsited in the process with the homologous the method of solution Finally introduce the Carrousel oxidize the latest research progress of the ditch and pointed out the future and main research

Diffusion: Read Plummer Chap. 7, sections 7.1-7.4,, 7.53, 7.5.8 Show that c(zt) Wroexpfzla)I,with a=2VDf, is a solution to Fick's second law of diffusion. ac(z, t) dc(zt) 2. a) What is the intrinsic carrier concentration in Si at 1100 C? b) Calculate the effective diffusivity (including first-order, charged-vacancy corrections)for As impurities in Si at 1100 C for two cases: 1)CAs=10 cm and ii)

Problem 1 Deal-Grove model states that the thickness of the oxide is related to a time constant r and two constants A and b by the relation

I. Plot resolution and depth of field as a function of exposure wavelength for a projection aligner with 100nm< A <500nm. Assume NA=0.26. Recalculate on the same plot for NA=0.41. Discuss the implication of these plots for the technologist that must manufacture transistors with 0.5 um
