مساله هایی که شامل برآورد و نتیجه گیری تحت قیدهای نامعادله خطی می باشند اغلب در مدل های آماری رخ می دهند. در این پایان نامه الگوریتمی برای حل مساله ی برنامه ریزی درجه دو از مینیمم سازی?(?)=?^ q?-2c? ارائه می کنیم که در آن q ماتریسی معین مثبت است و ? در درون مخروط محدب c={?:a??d} قرار دارد. در اینجا a ماتریس m×n است که لزوماً a رتبه کامل سطری نمی باشد. این الگوریتم سه مرحله ای، ساده است و همچنین ...

 در پژوهش حاضر رابطه بین ضریب حساسیت گیاه به تنش (Ky) و رطوبت بحرانی که در کمتر از آن گیاه دچار تنش می­شود (qc)، در قالب یک مدل ریاضی مفهومی توسعه داده شد. ارزیابی دقت این مدل با استفاده از داده­های حاصل از آزمایشات کشت گلخانه­ای گندم و کلزا در دو خاک لوم شنی و لوم رسی بررسی گردید. نتایج تحلیل مدل نشان داد که در یک Ky ثابت، عملکرد نسبی گیاه (Yr) با اختلاف رطوبت خاک از qc(qc-q) به‌صورت خطی کاهش ...

that in some parts of India cases occur, I shall be much obliged if you will insert tho following: series of questions in an yearly issue : 1. Has it been noticed in your district for long and, if so, does it occur at any particular seasons ? 2. What relation does its incidence bear to the common malarial fevers ? Do these present any unusual symptoms or exhibit any increase in virulence at the...

In this paper, an update method of Q-value is proposed to increase the learning rate of Q-learning. When Q-value of executed action is small, even if it is an optimal action, the learning becomes longer because the frequency to be executed again becomes lower. The proposed method increased the execution frequency of optimal action by forcefully increasing the Q-value through the Q-value update ...

The results reported in Chapter 3 are consistent with the premise of this dissertation that a comprehensive understanding of how ethical leadership works requires a closer look at the variation in followers’ expectations of the leader. To date, such empirical research on follower expectations of ethical leadership has been limited. However, Chapter 3 belongs to a small group of studies that rev...

Qbeta replicase, in the presence of Mn(++), can use various RNAs as templates for synthesis of full-length RNA products and can also use Qbeta plus-strand RNA as template in the absence of host factors.

We give an algorithm for counting points on arbitrary ordinary elliptic curves over finite fields of characteristic 2, extending the O(log q) method given by Takakazu Satoh, giving the asymptotically fastest point counting algorithm known to date.

drives are designed to increase product performance and system efficiency. One such motor type which can benefit from digital control is the switched reluctance (SR) motor. The SR motor brings advantages in both cost and reliability over other types of adjustable speed drives. These include its simple mechanical construction, high efficiency and high power density. On the other hand, large torq...

in this paper we will prove that the simple group g2(q) where 2 < q = 1(mod3)is recognizable by the set of its order components, also other word we prove that if g is a nite group with oc(g) = oc(g2(q)), then g is isomorphic to g2(q).

in this paper we show that if q is a power of a prime p , then the projective special linear group psl(2, q) and the stabilizer of a point of the projective line have maximum sum element orders among all proper subgroups of projective general linear group pgl(2, q) for q odd and even respectively
