当人们谈起网络的时候…

这是个有趣的实验:当有人谈起"计算机"这个词语,第一时间浮现在头脑中的图景会是什么呢?如果换成"网络"这个词语,最先在头脑中"看"到的图景又会是什么呢?无论结果如何,后者的回答种类一定比前者丰富得多.笔者搜集到几十种不同的答案,有的人"看"到一大堆乱缠的网线;有的人"看"到一台交换机;有的人"看"到整个网吧;有的人"看"到拓扑图(这常常是信息技术教师给出的答案).     

关于找工作这茬事儿

<正>无论在中华英才网的"职业讲习所",还是"职场讲坛",听到最多的就是怎么样找到一份好工作的问题。似乎有太多的人找工作不顺心,工作不开心,生活也不舒心。具体说来,有的想找工作但苦于没有经验,有的感慨专业对口的工作太少,或者是专业知识博而不精,自我感觉没有竞争力,有的干脆就是根本不知道自己喜欢什么,能干什么。这些问题看起来可怕,仔细分析起来,其实并不困难。     

汽车设计中自然与非自然限制因素的应用

设计心理学在产品设计过程中占有重要地位,对设计心理学的研究能够帮助设计师设计出结构更加合理,造型更加美观,使用更加方便安全,能更好的满足、服务人们生活的产品。每件产品都有特定的局限性,都受物理和现实因素的制约。在某种限制条件下,这些自然或非自然的限制因素才给各种具有自身特色产品的问世提供了"理由"和"条件"。汽车这种产品对自然与非自然限制因素涉及到较多方面,尤其是对于强迫性功能和自然匹配法则,正是这些限制因素才构成了汽车这种产品的和谐和统一。只有充分利用这些功能和法则才能设计出更加合理化人性化的汽车产品。     

雕塑与自然

当下流行的后现代主义是对现代主义的一种批判思潮。它反对现代主义的工具理性,提出科学技术是把"双刃剑";它反对人类中心主义,提出人是世界的一部分,主张重建人与自然、人与人之间的自然和谐关系;它反对权威中心,倡导多元,强调不确定性和差异性。这些都体现出后现代艺术在机械统驭状态下对自然和谐的一种回归。在如此时代背景下,后现代主义的艺术,具体至雕塑艺术,试问其最佳状态如何?"自然"无疑是较佳答案。

小学信息技术课的教学原则

作为教研员,笔者听了不少信息技术课,有的是公开课、评比课,这些课常有"作秀"之嫌,虽然理念新颖、设计巧妙,但大多一线教师无法模仿,缺乏实用性;有的是推门课、随堂课,这些课多是常态课,虽然比较真实,但因多种因素导致课堂效率低下.

Fluid-structure interaction modeling of complex parachute designs with the space-time finite element techniques

In recent years we introduced a number of enhancements to the space-time techniques we developed for computer modeling of Fluid-Structure Interaction (FSI) problems. These enhancements, which include more sophisticated fluid-structure coupling and improved mesh generation, are enabling us to address more of the computational challenges involved. Our objective here is to demonstrate the robustness of these techniques in FSI modeling of parachutes involving complex designs. As a numerical example, we have selected a conceptual parachute design with geometric complexities resembling those seen in some of the advanced parachute designs proposed and tested in recent times. We describe our FSI modeling techniques and how we compute the descent and glide performance of this conceptual parachute design.     

Algorithms for constructing optimal controllers for gaslift operation

We consider the optimal stabilization problem for delivered gas and gaslift operation debit for oil wells. Under certain natural assumptions, the general problem reduces to a linear-quadratic control problem that lets us find program controls and trajectories on which we further construct the optimal controller with respect to all phase coordinates and a (debit) part of them in both continuous and discrete case. For a special case, numerical results are illustrated with graphs that let us use this method in oilfield practice.

A discussion on performance value versus performance order

Ordinal optimization techniques help us locating “good” designs efficiently. Previous studies of ordinal optimization define the “good” designs as those coming at the top of the “order” of performance. In this study, we argue that with the help of practical prior knowledge and observations, we can establish quantitative relationship between the good design found and the performance “values” of it. Therefore, the analysis of ordinal optimization can be carried out to identify designs that are good by some criterion of their performance “values.”

Enforcing Efficient Equilibria in Network Design Games via Subsidies

The efficient design of networks has been an important engineering task that involves challenging combinatorial optimization problems. Typically, a network designer has to select among several alternatives which links to establish so that the resulting network satisfies a given set of connectivity requirements and the cost of establishing the network links is as low as possible. The Minimum Spanning Tree problem, which is well-understood, is a nice example.In this paper, we consider the natural scenario in which the connectivity requirements are posed by selfish users who have agreed to share the cost of the network to be established according to a well-defined rule. The design proposed by the network designer should now be consistent not only with the connectivity requirements but also with the selfishness of the users. Essentially, the users are players in a so-called network design game and the network designer has to propose a design that is an equilibrium for this game. As it is usually the case when selfishness comes into play, such equilibria may be suboptimal. In this paper, we consider the following question: can the network designer enforce particular designs as equilibria or guarantee that efficient designs are consistent with users’ selfishness by appropriately subsidizing some of the network links? In an attempt to understand this question, we formulate corresponding optimization problems and present positive and negative results.     

A novel formal verification approach for RTL hardware IP cores

We present a promising formal verification methodology based on the inductive approach using the imPROVE-HDL tool. This methodology is dedicated for RTL IPs or IP-based digital/logic hardware designs to prove the correctness of their temporal properties related to the control-dominated architecture model. Each temporal property can be checked through the IP interface where all properties have to be proved or disproved. We developed a new methodology to generate the appropriate environment of the IP interface according to the design context (master, slave, arbiter and decoder) before starting the verification of all properties one by one. When all temporal properties are verified, we generate some test sequences that contain a complex scenario to check the compatibility between all properties. We implemented our methodology to generate the appropriate environment and applied the inductive approach to verify various properties of two real IP designs using the imPROVE-HDL tool developed by TNI-Valiosys. The first design is an RTL IP-based digital hardware dedicated for real time video processing, where the second one performs an AHB to AHB Bridge. On these designs, we successfully proved few properties and discovered a design violation.

Design of piezocomposite materials and piezoelectric transducers using topology optimization— Part III

Summary Following the topic introduced in [1, 2] this paper discusses the design of piezoelectric transducers used in applications such as acoustic wave generation and resonators. These applications require goals in the transducer design such as high electromechanical energy conversion for a certain transducer vibration mode and narrowband or broadband response. The development of these devices has been based on the use of simple analytical models, test of prototypes, and analysis by the finite element method. However, in all cases the design is limited to a parametric optimization where only some dimensions of a chosen transducer configuration are optimized. By changing the topology of these devices or their components, we may obtain devices with better performance since the design space of solutions is enlarged. Based on this idea, we have proposed the use of topology optimization for designing these devices. This method consists of finding the distribution of the material and void phases in the design domain that optimizes a defined objective function. The optimized solution is obtained using Sequential Linear Programming (SLP). Considering acoustic wave generation and resonator applications, three kinds of objective functions were defined: maximize the energy conversion for a specific mode or a set of modes; design a transducer with specified frequencies; and design a transducer with narrowband or broadband response. Although only two-dimensional plane strain transducer topologies have been considered in order to illustrate the implementation of the method, it can be extended to three-dimensional topologies. Transducer designs were obtained that conform to the desired design requirements and have better performance characteristics than other common designs.
