告别月光族 理财软件&工具新年大推荐

俗话说,“你不理财,财不理你“,很多朋友可能都清楚自己的收入,但却不知道自己的消费和支出,所以每个月下来都是“月光族“。这就是由于头脑中没有“理财“的概念引起的,在新的一年开始时,我们有必要共同来探讨一下个人理财的问题,广义的理财不但包括财产资金的管理,还包括利用现在的资金“生财“,但是由于投资顶目有风险,各行各业差别也很大,因此在市专题中,我们主要探讨狭义的理财,那就是对资金的管理,让账目更明确,让消费更理性,日常生活中不但要开源,更要节流,用心理财,你才能做到“心中有账,手里有财“,从此告别“月光族“!

《数码摄影》创刊于新世纪,是本年青的杂志,有年青的感觉,年青的朝气,也有年青的躁动。杂志是智者,面对是朋友,所以我喜欢看各种杂志的卷首语,如沐春风,如听秋雨,有所闻,有所感,很难得,张韬也好,登登也好,如能再精深一些,配图收录会是很不错的图文集。     

家用车的逆袭——铃木雨燕全面改装密

正提到代步车这个词,可能很多人都会说出无数的车型,这其中就包括了早在2005年就上市的雨燕,它来自日本的小型车专业户铃木,对于当时的消费者来讲,雨燕有着得天独厚的优越条件,靓丽的外形以及超级别的配置,唯有那台G13B引擎多少有些拿不出手,不过小MINI的称号依旧换来了相当多的支持者,随着小改款的推出,引擎也从落后于时代的G13B换成了相对先进的M15A,双顶凸轮轴加上VVT,这些足以进入精品小型车的行列,将它视为改装对象的人也越来越多。用心修饰性格巨变和众多A0级小车相比较而言,雨燕的外观还是属于相当温顺的,甚至多少有些可爱,对于喜欢这种性格的女生来讲,的确是再合适不过了,不过对于那些喜欢追求速度和与众不同的男生来讲,就未必合适了,不过好在雨燕的可塑性还是很高的,通过了一些相当用心的手段进行修饰之后,一番凶悍的景象还是得到了良好的呈现,随着外观的变化,     

魔兽·社会·人

一个警察玩魔兽,后来殉职,有玩家在游戏里为他组织了葬礼,很多战友前来祭拜。重庆一个魔兽公会的会长在网上卖号,打算凑两三千块钱给妻子治病,结果无数玩家慷慨解囊。还有一些让人哭笑不得的妙人。比如三季稻,人称三哥,他是国服里的一个传奇人物,独来独往,专杀小号。他不参加任何公会,也不参加任何活动,没有人知道他的真实身份。有个联盟玩家给自己的ID起名叫部落不是东西,然后到处躲避部落的追杀,历尽艰辛,乐此不疲。还有一玩家一根筋要当大奸商,不练级,不打怪,只是在不同种族之间倒买倒卖,囤货居奇,最终控制整个服务器的经济命脉。其实,游戏和现实世界一样.不管是谁,总有点追求。在《魔兽世界》里,有人求升级,有人求装备,有人享受打到BOSS的过程,有人追求领导公会的快感,但也有BJ这样的游侠——他最大的乐趣是发掘游戏里面各种稀奇古怪的地方。他会一个人去爬山、游泳、客串做奸商,躲在没人的地方钓鱼,或者和小妹妹在山顶看日出。为了抓一只宠物,他可以在树下连续盯上40多个小时,如痴如醉,跟谈恋爱一样。走出游戏,又觉得自己很傻。BJ今年33岁,是一个程序员,家住南京,有家庭,有事业,热爱生活。

Voices that cannot be heard: Can shyness explain how we communicate on Facebook versus face-to-face?

Social networking sites have gained popularity among all populations, especially young adults. Personality traits were found to be predictive of how individuals use social media. Therefore, this study sought to examine the association between shyness and self-disclosure to a Facebook friend as well as self-disclosure to a face-to-face friend. Two studies were conducted. The first study tested how shyness and social loneliness are related to self-disclosure to a Facebook friend to whom an individual talks most often. The second, follow-up study tested how shyness is related to self-disclosure to a Facebook friend to whom a person speaks to only though Facebook, and also to a face-to-face friend to whom the participants talk only face-to-face and never through Facebook. Participants were college students from a large research university in the United States. Study 1 found a negative association between shyness and self-disclosure to a Facebook friend. Study 2 found a negative association between shyness and self-disclosure to a face-to-face friend. The theoretical implications and limitations are discussed.     

Design of phononic materials/structures for surface wave devices using topology optimization

We develop a topology optimization approach to design two- and three-dimensional phononic (elastic) materials, focusing primarily on surface wave filters and waveguides. These utilize propagation modes that transmit elastic waves where the energy is contained near a free surface of a material. The design of surface wave devices is particularly attractive given recent advances in nano- and micromanufacturing processes, such as thin-film deposition, etching, and lithography, which make it possible to precisely place thin film materials on a substrate with submicron feature resolution. We apply our topology optimization approach to a series of three problems where the layout of two materials (silicon and aluminum) is sought to achieve a prescribed objective: (1) a grating to filter bulk waves of a prescribed frequency in two and three dimensions, (2) a surface wave device that uses a patterned thin film to filter waves of a single or range of frequencies, and (3) a fully three-dimensional structure to guide a wave generated by a harmonic input on a free surface to a specified output port on the surface. From the first to the third example, the resulting topologies increase in sophistication. The results demonstrate the power and promise of our computational framework to design sophisticated surface wave devices.     

Machine scheduling with job class setup and delivery considerations

We study machine scheduling problems in which the jobs belong to different job classes and they need to be delivered to customers after processing. A setup time is required for a job if it is the first job to be processed on a machine or its processing on a machine follows a job that belongs to another class. Processed jobs are delivered in batches to their respective customers. The batch size is limited by the capacity of the delivery vehicles and each shipment incurs a transport cost and takes a fixed amount of time. The objective is to minimize the weighted sum of the last arrival time of jobs to customers and the delivery (transportation) cost. For the problem of processing jobs on a single machine and delivering them to multiple customers, we develop a dynamic programming algorithm to solve the problem optimally. For the problem of processing jobs on parallel machines and delivering them to a single customer, we propose a heuristic and analyze its performance bound.     

A self-adaptation scheme for workflow management in multi-agent systems

Business processes, operational environment, variability of resources and user needs may change from time to time. An effective workflow management software system must be able to accommodate these changes. The ability to dynamically adapt to changes is a key success factor for workflow management systems. Holonic multi-agent systems (HMS) provide a flexible and reconfigurable architecture to accommodate changes based on dynamic organization and collaboration of autonomous agents. Although HMS provides a potential architecture to accommodate changes, the dynamic organization formed in HMS poses a challenge in the development of a new software development methodology to dynamically compose the services and adapt to changes as needed. This motivates us to study and propose a methodology to design self-adaptive software systems based on the HMS architecture. In this paper, we formulate a workflow adaptation problem (WAP) and propose an interaction mechanism based on contract net protocol (CNP) to find a solution to WAP to compose the services based on HMS. The interaction mechanism relies on a service publication and discovery scheme to find a set of task agents and a set of actor agents to compose the required services in HMS. We propose a viable self-adaptation scheme to reconfigure the agents and the composed services based on cooperation of agents in HMS to accommodate the changes in workflow and capabilities of actors. We propose architecture for our design methodology and present an application scenario to illustrate our idea.     

Distant Collision Response in Rigid Body Simulations

We use a finite element model to predict the vibration response of objects in a rigid body simulation, such that rigid objects are augmented to provide a plausible elastic collision response between distant objects due to vibration. We start with a generalized eigenvalue decomposition of the elastic model to precompute a response to an impact at any point on an elastic object with fixed boundary conditions. Then, given a collision between objects, we generate an approximate response impulse to distribute to other objects already in contact with the colliding bodies. This can lead to distant impacts causing an object to slip, or a delicate stack of objects to fall. We also use a geodesic distance based spatial attenuation approximation for travelling waves in objects to respond to an impact at one contact with an impulse at other locations. This response ultimately allows a long distance relationship between contacts, both across a single object being struck, but also traversing the contact graph of a larger collection of objects. We qualitatively validate our approach with a ground truth simulation, and demonstrate a number of scenarios where a long distance relationship between contacts is valuable.     

A kernel language for programmed rewriting of (hyper)graphs

The paper presents a formalism for rewriting (hyper)graphs in a controlled manner. This formalism is essentially a simple programming language with productions, that is rewriting rules, playing the role of basic instructions. Programs in this language are built from productions by means of rather standard constructors, including a parallel composition. They may contain parameters to point to specific elements of graphs to which they are supposed to be applied. Programs are intended to describe how to transform a graph and a valuation of parameters in this graph in order to reach a resulting graph and a resulting valuation of parameters.     

A superscalar simulation employing poisson distributed stalls

This paper presents a statistical approach to estimating the performance of a superscalar processor. Traditional trace-driven simulators can take a large amount time to conduct a performance evaluation of a machine, especially as the number of instructions increases. The result of this type of simulation is typically tied to the particular trace that was run. Elements such as dependencies, delays, and stalls are all a direct result of the particular trace being run, and can differ from trace to trace. This paper describes a model designed to separate simulation results from a specific trace. Rather than running a trace-driven simulation, a statistical model is employed, more specifically a Poisson distribution, to predict how these types of delay affects performance. Through the use of this statistical model, a performance evaluation can be conducted using a general code model, with specific stall rates, rather than a particular code trace. This model allows simulations to quickly run tens of millions of instructions and evaluate the performance of a particular micro-architecture while at the same time, allowing the flexibility to change the structure of the architecture.     

Analysis of dimensions and tolerances in computer-aided mechanical design

The paper sets forth a theory to explain how dimensions and views combine to specify the shape of a mechanical component. It provides a method to determine whether a component is under, over, or exactly defined by a given dimensioning scheme. Measures for assessing the quality of a scheme are proposed. A solution is offered to a problem of tolerancing: given a toleranced dimensioning scheme, find the resulting tolerances between undimensioned parts of a component.     

Learning criterion and inductive behaviour

Inductive behaviours may be classified according to their aim. We intend to show that there are at least two kinds of inductive behaviours. Most of the publications seem to take into consideration only one of these: to copy as exactly as possible the behaviour of a probability process. After a brief discussion to explain the necessity of a learning criterion and a recall about one criterion, representative of most of them, we shall define a new criterion, and show why it is better fitted to learn the laws of a deterministic process from a set of observations.This criterion has been used to implement a program which builds an acceptor of natural language sentences in a CAI environment using a tutorial strategy, and then for a question answering device. As attractive as the results are, their improvement requires a semantic model. We give the basic principles of a model which we currently develop, and whose main feature is approximation.     

Elimination of artifacts due to occlusion and discretization problems in image space blurring techniques

Traditional computer graphics methods render images that appear sharp at all depths. Adding blur can add realism to a scene, provide a sense of scale, and draw a viewer’s attention to a particular region of a scene. Our image-based blur algorithm needs to distinguish whether a portion of an image is either from a single object or is part of more than one object. This motivates two approaches to identify objects after an image has been rendered. We illustrate how these techniques can be used in conjunction with our image space method to add blur to a scene.
