hessian boots

At the windows of the houses men could be seen in military coats and hessian boots , laughing and strolling through the rooms . in the cellars , in the storerooms similar men were busily looking after the provisions ; in the courtyards they were unlocking or breaking open the doors of sheds and stables ; in the kitchens they were making up fires , and with bare arms mixing , kneading , and baking , and frightening , or trying to coax and amuse , women and children 房屋的窗戶里,閃現著穿軍大衣和短靴的人們,他們嘻笑著出入于各個房間在地窖和地下室里,這些人喧賓奪主地款待自己在院子里,這些人打開或砸開披屋和馬廄的門在廚房,則點燃爐灶,卷起袖子和面,烘烤和煎炸,恐嚇,調笑和愛撫婦女和兒童。

In the second part , a decomposition method for solving semidefmite quadratic programming with box constraints is proposed . a regular splitting of the hessian matrix of the problem is used in the algorithm . the convergence of the algorithm is proved under certain assumptions , the numerical results are also given 第二部分把解邊界約束正定二次規劃問題的正則分解算法推廣到求解邊界約束半正定二次規劃問題,在理論證明的基礎上還進行數值檢驗,結果說明算法是有效的。

Nobody came near them , and their movements showed a mechanical regularity ; their forms standing enshrouded in hessian wroppers - sleeved brown pinafores , tied behind to the bottom , to keep their gowns from blowing about - scant skirts revealing boots that reached high up the ankles , and yellow sheepskin gloves with gauntlets . the pensive character which the curtained hood lent to their bent heads would have reminded the observer of some early italian conception of the two marys 沒有人走近她們她們的動作像機械一樣地一致她們站在那兒,身上裹著麻布罩衫這是一種帶袖子的黃色圍裙,從背后一直扣到下擺,免得讓風吹來吹去穿著短裙,短裙下面是腳上穿的靴子,靴子的高度到達了腳踝以上,手上戴的是帶有護腕的羊皮手套。

However , some of them are restrictive . for some of these methods , the convergence is not known in this paper , based on a modified bfgs update formula proposed by li and fukushima , we propose a modified bfgs method for solving equality constrained optimization 本文在li - fukushima提出的求解無約束問題的修正bfgs公式的基礎上,對求解等式約束問題的sqp算法,提出一個保證qp子問題的目標函數的hessian陣的正定性的修正方案。

3 ) evolves perona - malik equation to the form of weighted smoothing in two orthogonal directions . brings hessian method , which is an approach to extract the image feature direction , into the technology of smoothing image 3 )推導perona ? malik方程為在相互垂直方向不同程度平滑的形式,將提木于柿微分方程的圖街個滑技術及其應用研穴摘要取圖像特征方向的hessain方法應用到圖像平滑技術中。

Observing that the newton direction is always a descent direction of the square norm of the gradient , even if it is not a descent direction of the objective function , which will result some linear research - such as armijo research or wolfe research - fail 因此,該算法是頗受歡迎的算法之一。然而,若問題的目標函數的hessian陣不正定,則不能保證算法產生的方向是目標函數的下降方向。

Due to the convergence of cg method is strongly dependent on the condition number of the hessian , the inexact newton method with cg subiterations will be powerful if these cg subiterations are replaced by preconditioned cg subiterations with suitable preconditioner 由于cg法的收斂狀態強烈的依賴于海色陣的條件數,所以用條件預優共軛梯度法( pcg )替代cg法會得到更好的效果。

Based on this observation , we develop a newton - filter method in such a way that at each step , the method generates a point such that either the objective function value or its gradient descreases sufficiently 此時,常用的線性搜索(如armijo搜索和wolfe搜索等)可能失敗。另一方面,不管目標函數的hessian陣是否正定, newton方向一定是目標函數的梯度的模函數的下降方向。

He boldly assumed the whole responsibility of it all ; and his clouded intellect found justification in the fact that among the hundreds of thousands of men who perished , there were fewer frenchmen than hessians and bavarians 他勇敢地承擔了事件的全部責任,他神志不清地竟然從幾十萬犧牲者中法國人少于黑森人和巴代利亞人這樣一事實中找到了辯解的證據。

All these westphalians and hessians napoleon is leading against us would not have come to fight us in russia , and we should not have gone to war in austria and in prussia without knowing what for 那時,拿破侖所率領的這些威斯特法利亞人和黑森人就不會跟隨他到俄國來了,我們也不會莫名其妙地到奧國和普魯士去打仗了。

Others claimed that the hessian soldier rose from the grave to lead the hessian soldiers in a charge up nearby chatterton hill , not knowing that the hill had already been taken by the british 另一些人則認為這個黑森士兵還不知道附近的查特頓山已被英國人占領,他從墳墓里出來便是要領導其他黑森士兵向那兒沖鋒。

In this paper , we study classical solution to the first initial - boundary value problem of parabolic hessian equation : where is a bounded , uniformly ( k - l ) - convex domain in rn with smooth boundary 本文研究如下的拋物型hessian方程的第一初邊值問題的古典解:其中是r ~ n中有界一致( k - 1 )凸的光滑區域。

But one of its disadvantages is that the cost of solving the newton equation is large . the reason is that the choleski factorization of the hessian v ' f is expensive 但是它的缺點之一是花費很大,原因是在解newton方程時海色陣? ~ 2f的choleski分解的花費很大。

Small rootballs are usually wrapped with hessian and ropes , or enclosed in a timber box . large rootballs have to be secured in a steel box reinforced with steel beams 細小的根團需以麻布及繩封綁,或放進木盒內;龐大的根團則須放進鋼箱,再用方鋼柱穩固。

He saw distinctly one bandy - legged old french officer , wearing hessian boots , who was getting up the hill with difficulty , taking hold of the bushes 他清楚地看見一個年老的法國軍官,他邁開套著鞋罩的外八字腳攀緣著灌木,費勁地登上山坡。

To the right and left of the post stood rows of french soldiers , in blue uniforms , with red epaulettes , in hessians and shako 柱子左右兩邊,站著排成行的法軍,他們身穿帶有紅色穗條肩章的藍制服,腳登皮靴,頭戴圓筒帽。

I represent the hessian trading company . we ' re interested in importing a complete bottling machine for exhibit and sale in our country 我是哈森貿易公司的代表,我們有興趣進口一整部裝瓶機,以備在我國展示和銷售。

Recently , there comes another kind of cross - platformed communication protocol ? hbwsp ( hessian binary web service protocol ) 當前,出現了另一種跨平臺的通信協議hbwsp ( hessianbinarywebserviceprotocol ) 。

There have developed some technique to ensure the positive definiteness of the hessian of the quadratic objective function 迄今為止,已提出了多種保證子問題的目標函數的hessian陣的正定性的方案。
