Two scheduling problems in group technology with deteriorating jobs
|
|
This paper considers single-machine scheduling problems in group technology with the jobs' processing times being simple linear functions of their start times.
|
|
Impact of operating costs on investment strategies in new technology adoption with a further new technology anticipated
|
|
This paper studies a dynamic duopoly model in which two firms compete in adoption of current technology with a further new technology anticipated.

A number of q,t-analogues of this fact were conjectured in [10]; the present paper proves most of those conjectures, as well as some new identities suggested by the proof technique.
|
|
In this paper we present a technique for proving bounds of the Boas-Kac-Lukosz type for unsharply restricted functions with nonnegative Fourier transforms.
|
|
This technique gives rise to several "epsilonized" versions of the Boas-Kac-Lukosz bound (which deals with the case f(u) = 0, |u| ≥ 1).
|
|
The basic technique uses factorization of group elements and Gel'fand-Tsetlin bases to simplify the computations, and may be extended to treat the computation of Fourier transforms of finitely supported distributions on the group.
|
|
Our technique applies, in particular, to the Shannon and Journe wavelet sets.

In this note we present a very simple method of proving that some hyperbolic manifoldsM have finite sheeted covers with positive first Betti number.
|
|
The method applies to the standard arithmetic subgroups ofSO(n,1) (a case which was proved previously by Millson [Mi]), to the non-arithmetic lattices inSO(n,1) constructed by Gromov and Piatetski-Shapiro [GPS] and to groups generated by reflections.
|
|
(HereM3 denotes the vector space of 3×3 matrices over k andp>amp;gt;3.) The method of proof involves an induction, and is potentially of wide applicability.
|
|
The proof is based on a variant of Moser's method using time-dependent vector fields.
|
|
In the second part we apply this method to obtain pseudo-Riemannian homogeneous manifolds with real Killing spinors.

The purpose of this paper is to discuss how the value of high-tech firm can be rationally valued by taking into account managerial flexibility when its future revenue is uncertain, thereby the firm's manager can make rational investment decisions.
|
|
Besides the needs arising from large-scale high-temperature plants, the high tech developments, such as micro chemo-mechanical systems and high-power electronics, provide new challenges to structural integrity technology.

| This paper is the study of the gas communication andthe loss of hyd rostatic head of cement column caused by the gelling of cement slurry in the case of simulating the changes of temperature and pressuse in the well bore. From the results of experiments, it has been proved to be true that the gas communication and the loss of hydrostatic head of cement column caused by the gelling of cement slurry are serious, and the loss of hydrostatic head of cement column caused by the gelling of cement slurry can be calculated... This paper is the study of the gas communication andthe loss of hyd rostatic head of cement column caused by the gelling of cement slurry in the case of simulating the changes of temperature and pressuse in the well bore. From the results of experiments, it has been proved to be true that the gas communication and the loss of hydrostatic head of cement column caused by the gelling of cement slurry are serious, and the loss of hydrostatic head of cement column caused by the gelling of cement slurry can be calculated quantatively after experimentation and mathematical analysis. This makes it possible that a sound basis is provided for taking technical measures to prevent oil, gas and water communication in the casing cementing job. | 本文是在摸擬井身溫度和壓力變化的情況下,對水泥漿柱由于水泥膠凝引起的“失重”和氣侵的研究。從實驗研究的結果證實了水泥膠凝引起的“失重”和氣侵是嚴重的,而水泥漿膠凝引起的“失重”,通過實驗和數學分析后是可以作到定量計算的,這就可能給固井施工中,為防止油、氣、水竄工藝技術措施,提供可靠的基本依據。 | Some energy saying measures were carried out in the FCC unit of the 2nd Refinery during 1980,including:the use of CO-combustion promotor,energy recovery from flue gas,rearrangement of heat exchanges,steam generation by waste heat,and boiler feed water preheat by low-temperature effluents,resulting a decrease of energy consumption by 65×10~4 kcal/ton of feed. | 石油二廠流化催化裂化裝置在1980年又進行了節能技術改造.主要項目是:采用助燃劑的完全再生,煙氣能量回收,換熱流程調整,余熱發生蒸汽,以及鍋爐水預熱回收低溫位熱等.通過改造,裝置能耗下降到65萬千卡/噸原料油. | A techno-economic analysis with, respect to the energy-savings in refinery was presented and a number of proposals were recommended accordingly. | 作者通過參加煉油廠節能規劃工作,對煉油廠節能中的一些技術問題,進行了技術經濟分析,提出了一些看法和建議。 |   | << 更多相關文摘 |
