MEMS
Microelectromechanical Systems (MEMS) and/or Nanoelectromechanical Systems (NEMS) is a newly rising interdisciplinary technology. The mechanical design of MEMS and/or NEMS is one of the frontiers of mechanical engineering. The traditionary mechanical design methods and theories can not be used in MEMS design due to surface effect and size effect. The up-to-date development of the study of MEMS has brought about varies kinds of micro-components. When these micro-components are used to build up a microelectromechanical system to obtain a definite function, the theory of MEMS design should be developed. There are some existing problems of the fundamental design issues of MEMS about microtribology, microthermodynamics, microhydrodynamics, micromechnics of materials and micromechanisms. These problems have heavily restricted the development of MEMS, and the fundamental design issues of MEMS should be studied as quickly as possible [14].
As the influences of surface forces on the micromachines are very large due to the surface effect with an increase in the ratio of surface area to volume and the small clearance between micro-components, the analysis of forces on micromachines is different from that on marcomachines. Some neglected influences in marcomachines should be considered in the design of micromachines. On the other hand, the change of material properties and mechanical behavior should be considered duo to the size effect on material strength. Obviously, the surface effect and the size effect are two key problems of many fundamental design issues to be studied in MEMS. These two kinds of effect affect each other and they can not be studied separately. So, the two representative problems about the understanding of the mechanical behavior of MEMS materials and the unwanted typical “sticking” phenomenon in MEMS should be theoretically and experimentally studied [18]. As discussed above, the study of these two relating problems are firstly brought forward in this dissertation and this dissertation takes up two key points among the existing problems in the development of MEMS, the mechanical behavior of MEMS materials and the stiction phenomenon in MEMS, for investigating theoretically and experimentally in detail. New micromechanical models and approaches are proposed. The specific works finished and main innovative contributions of this dissertation are as follows:
Firstly, a novel, direct and convenient method for micromechanical property measurements by beam bending using a nanoindenter has been developed, and a microtensile test device with a magnet-solenoid actuator and a fibre-optical displacement sensor has been designed and constructed to investigate the tensile mechanical properties of polysilicon films. Based on the investigation of mechanical properties of coating/substrate system by nanoindentation [30], the data obtained from nanoindentation are certified unsuitable to be used in the study of deformation of microcantilever because of the emergence of phase transformation under indentation [37]. Thus, a method for micromechanical property measurements by beam bending using a nanoindenter has been demonstrated [20]. A systematic analysis of the measurement principle and influences has been made [11]. In order to achieve the net deformation properties of a thin coating, both load-penetration depth and load-penetration depth squared plots have been demonstrated to be necessary if a more complete understanding of coating/substrate system behavior is to be gained [1], which has been suggested to be a rule to evaluate the mechanical properties of thin solid films[15]. In the meantime, in the deflection of microbeams, the influence of the indenter tip pushing into the top of the microbeams and the curvature across its width must be considered [21]. With these influences considered, the mechanical properties of microcantilever deformation can be obtained [23]. In order to investigate the mechanical properties of microstructures under purely tensile pulling procedures, the optimum configuration and geometry for a magnet-solenoid force actuator has been presented, enabling its application to the design of microtensile test device [16]. The electromagnetic force actuators have distinct advantages for applications involving very small displacements, which include linear operation, low hysteresis, no friction and direct electrical control. The magnet within a coil has a low stiffness relative to the mechanism and will readily be self-align to the primary translation axis and so all but eliminate crossaxis forces. This low stiffness coupling also reduces the transmission of mechanical vibration between the stage and the frame. The displacement of the sample is measured with two groups of optical fibers bundled together having a realizable accuracy of 50nm in stable thermal conditions. This microtensile test device is used to measure the mechanical properties of polysilicon films. During the test, the tensile stress linearly increases with the displacement of the precise stage, and the stress curve manifests no yield point until fracture. The specimen has no necking, and no plastic deformation is observed. The Young's modulus are obtained by calculating the slope of the stress-strain curve using a least-squares fit [22、4]. The Young’s modulus of polysilicon films are also calculated by either the isotropic model of Reuss-Voigt model, Shtrik-Hashin model or texture model. The bounds for the {110} in-plane elastic constants are modeled to be in good agreement with the results of the tensile experiments. It has been found that the measured average values of Young’s modulus by tensile tests falls within the theoretical bounds of texture model [31]. The test data accounts for the uncertainties of the reported Young’s modulus mean values obtained for polysilicon. This data may be used in the future reliability design of polysilicon MEMS.
Secondly, the size effect of the typical manufactured component on bending strength of polysilicon microcantilever beams and tensile strength of polysilicon thin films has been systematically investigated. Statistical analysis of bending strength [7] and tensile strength [8] for various specimen sizes predict the size effect of specimen length, width，cross-section area，surface area, and volume. Especially，the size effect of specimen width on tensile strength has been theoretically and experimentally studied. It shows that the result concluded by Toshiyuki tsuchiya, which was stated that statistical analysis of tensile strength predicted no size effect of specimen width, is incorrect. The Weibull distribution probability function is adopted to represent such tensile strength variations for polysilicon brittle materials [24]. Statistical analysis of the specimen size effects on the tensile strength predicts the size effects on the length, the surface area and the volume of the specimens due to microstructural and dimensional constrains. The fracture strength increases with the increase of the ratio of surface area to volume. In such cases the size effect can be traced back to the ratio of surface area to volume as the governing parameter [13]. The test data accounts for the uncertainties in mechanical properties and may be used in the future reliability design of polysilicon MEMS [26].
Thirdly, the rupture physics and crack origin of polysilicon thin films are analyzed by means of AFM, SEM and TEM [36]. The maximum-likelihood method is also applied to analyze the fracture origin of polysilicon films combining with the cross-section photo of fracture face [24] .The fracture behavior indicates that the fracture origin of polysilicon thin films is located on the surface of the specimens. The surface roughness is proved to be the main fracture origin of polysilicon thin films for the first time and the effect of surface roughness on tensile strength has been theoretically and experimentally studied, which can be expressed by fracture mechanics [38]. For brittle materials the strength is governed by the maximum flaw size, typically at the surface. Clearly the processing route and resulting surface roughness have a strong influence on strength. The valley is a stress concentration and a flaw at the surface. Furthermore, the mechanical properties of polysilicon thin films coated with OTS film are also investigated. It is found that tensile strengths of polysilicon thin films are enhanced greatly when they are coated with OTS films. It is clearly that not only the tribology properties and anti-stiction properties of microstructures can be improved but also the mechanical properties of microstructures can be enhanced. These results would work as guidance for the design of MEMS materials.
Lastly, base on the investigation of the mechanical properties of microstructures the influence of capillary forces on sticking of a surface micromachined polysilicon microcantilever in ambient environment or the rinse liquid and the influence of quantum mechanical effect such as the Casimir effect on sticking and stability of a micro polysilicon membrane strip cavity structure in vacuum are investigated. Mechanical stability and sticking are the troublesome problems in microfabrication and operation processes when separations of components in MEMS are in the sub-micrometer regime. Some mechanical effect, including quantum mechanical effect should be taken into account for solving the problems. Capillary forces will play a dominant role on sticking in ambient environment or the rinse liquid. On the other hand, the magnitude of Casimir force is significant when the membranes work in vacuum without the effect of capillary forces. The Casimir effect may play an important role if the separations are small enough [9]. The corrections of roughness, conductivity, and temperature to the Casimir force must be considered for accurate account of their effects [32]. With nothing other than the Casimir force loading the strip, there exist a stable static equilibrium state and an unstable static equilibrium state, depending on the value of a dimensionless constant K [2、3]. The membrane strip will collapse if the value of K is larger than the critical value. Thus, the influence of capillary forces and the Casimir effect on sticking and stability of microstructures are investigated [6]. The study on the design of anti-sticking structures under different forces shows that sticking and stability of microcantilevers and micro membrane strip cavities has something to do with Young’s modulus of materials, surface properties, length of structures, thickness of structures and separation between the fixed surface and the deflecting component. But, it is independent of width of structures [39]. A map of the size design of anti-sticking structures has been proposed for the first time, which provides a way to check if a system with given dimensions and material properties will be in a stable equilibrium [34]. These results are expected to be useful for the design of MEMS, and of significance for establishing a framework of the design theory of MEMS.

RIAA/MPAA and file sharing
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In a way, pirating can help the music industry. Kind of in a try before you buy sort of way. I download music, then, if I like it and feel obliged to support the artist, I go to buy the cd, if I don't like it, I simply delete it. If it wasn't for piracy, I would buy NO music AT ALL, because I am not very up to date on music styles, so I would have no fucking idea what to buy.
Also, the RIAA and MPAA as well as whoever does the games mainly target sharers and not downloaders.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Exactly, that's why I think that file sharing is not so bad. If you download some mp3 files of a certain artist and you like it, you'll feel like buying their CD's and checking always for the music.
On other hand, if you don't like it, you delete it, it just takes space on your computer.
As I said earlier mp3 files can work as a promotion to the band too. Think of how many CD's can sell by just letting some internet users to download mp3. In fact, many new bands do so, to promote their music.
So, this also depends on the artist's opinion on this. If the artist thinks that it's OK to share their music then the music industry can't do anything, because they're not the authors of it. Besides, many music labels have had issues with music bands because of that, a music band says: hey, let's allow the people who visit our page to download some of our music, and then when the company sees this, start arguing with the artist, but at the end, it's just the artists desition.
This file sharing issue is mainly because of the music labels, most the artists are not that concerned about it. And the ones who are concerned are shitty artists like Metallica (they're actually shitty), Britney Slut, etc.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
One reason I don't buy music or movies is because everything these days has Digital Rights Management (DRM) technology in it. It's like putting your MP3 files on house arrest; it limits how many CDs, MP3 players, or computers you put them on. Basically, you are just leasing your songs. Do you want limited rights to your property?
That brings me to another point. The RIAA/MPAA vocabulary is bullshit. One word that bothers me is piracy. Pirates commit robbery and/or murder on the high seas, according to US law. Punishment for pirates - again under US law - is death. Not only is downloading music not robbery, but the RIAA/MPAA is not killing downloaders. However, I feel that it is just a matter of time before they try to. The proper term for illegally downloading is copyright infringement. Also, "intellectual property" pisses me off. How can thoughts count as property? They do not physically exist until they are transferred into a physical form, such as a CD/record/casette/etc..
Also, why the hell is the FBI and Secret Service helping their efforts? The FBI has much more to worry about (terrorism) and I didn't know that the Secret Service did anything other than protect government officials. Why should they be concerned about some guy with gigabytes of files on their computer?
The RIAA crossed the line with the lawsuits and the MPAA crossed the line with the shutting down of LokiTorrent and Suprnova (and the message left on LT REALLY pissed me off), not to mention the following lawsuits.
By the way, downloading is not stealing nor is it taking money away from the RIAA/MPAA. Nothing is physically gone; it was merely copied. Nobody took anything, therefore it is not theft and they lost no money. They may lose a potential sale, but that's not the only reason they could lose a sale. It could be a critic's review, a friend's bad experience, a bad video store, or any number of things. Those aren't illegal, are they?

How old are you? Apparently not old enough to know that on a lease, you're paying monthly, jackass. You buy your CD's they're yours, if they have that DRM or whatever on them, so be it, you can thank yourself, along with all the other pirates that were stealing.

What the hell are you talking about? Quit getting all technical and accept the fact you're a thief. They aren't going to kill anyone for stealing a few songs, possibly jail time, but no death, tool.

They aren't going to send uniformed police officers to your door to arrest you. Please, show reference as to where the FBI and SS are in on this with the RIAA/MPAA.

You're upset with the RIAA/MPAA because they shut down a big source of this multi-billion dollar theft? They didn't cross the line, they did what was legal, stopped theft. If not stopped, they surely have cut people down on downloading.

It is theft, you are taking something that isn't yours. You didn't create the album, nor was the album given to you, you're downloading the song illegally. I don't know where in the hell you kids come up with the lousiest things to defend yourselves, but face it, you're stealing. It's theft, there is no way around that. I don't care if you say "you're not physically taking anything," it's still theft. Again, you're taking something that isn't yours.
In a way, pirating can help the music industry. Kind of in a try before you buy sort of way. I download music, then, if I like it and feel obliged to support the artist, I go to buy the cd, if I don't like it, I simply delete it. If it wasn't for piracy, I would buy NO music AT ALL, because I am not very up to date on music styles, so I would have no fucking idea what to buy.
Also, the RIAA and MPAA as well as whoever does the games mainly target sharers and not downloaders.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Exactly, that's why I think that file sharing is not so bad. If you download some mp3 files of a certain artist and you like it, you'll feel like buying their CD's and checking always for the music.
On other hand, if you don't like it, you delete it, it just takes space on your computer.
As I said earlier mp3 files can work as a promotion to the band too. Think of how many CD's can sell by just letting some internet users to download mp3. In fact, many new bands do so, to promote their music.
So, this also depends on the artist's opinion on this. If the artist thinks that it's OK to share their music then the music industry can't do anything, because they're not the authors of it. Besides, many music labels have had issues with music bands because of that, a music band says: hey, let's allow the people who visit our page to download some of our music, and then when the company sees this, start arguing with the artist, but at the end, it's just the artists desition.
This file sharing issue is mainly because of the music labels, most the artists are not that concerned about it. And the ones who are concerned are shitty artists like Metallica (they're actually shitty), Britney Slut, etc.

Is Free Hosting Really Free?
Today, there are more choices than ever if you are looking for free hosting services. In fact, there are new companies popping up all the time offering some type of “free” hosting plans. Unfortunately, there are just as many companies going out of business and leaving their customers in a sort of hosting purgatory, unable to deliver the “free hosting for life” they had promised them and too often causing even more serious headaches.
With so many user complaints and horror stories surrounding free hosting, we decided to take a closer look and offer some insight for those considering it. So here’s the usual deal. To get “free” hosting, you must first pay a one-time setup fee that ranges from $35 to over $100 to transfer your domain. If you don’t already have a domain, you may also end up paying a premium of $35 or more for a new domain. You probably will also have to agree to become part of a forced advertising database, and receive daily email marketing, that your free host is selling to whomever they want. In return, you are promised “free hosting for life” that is restricted by how much disk space and monthly bandwidth you get. Your free host is hoping that you will exceed your allotted amount so they can upsell you to a paid hosting plan later.
Besides the fact that it’s not “free”, there are some other problems with this business model. To start with, your free host only gets paid by its customers one time – when they sign up – but they have to provide on-going service to them indefinitely. If for any reason new sales are down, there can be a big problem quick. Credit card fraud is also a costly problem for free hosting companies – it’s a favorite way for thieves to quickly check if a stolen card still works. To be profitable, a free host is dependent on a constant flow of enough setup fees from new customers. Which means they must keep operating costs low and advertising spending high. It’s important to understand how keeping their overhead as low as possible can directly affect the level of service that free hosts can provide their customers in the areas of uptime, security, data backup, customer service and tech support.
When it comes to uptime reliability, you want to be sure your free host owns their own servers. If your free host is actually reselling hosting on a third party’s servers and there is a problem, they may not be able to control when and how it gets fixed. Or worse, if there’s a dispute between your free host and the third party hosting company, your Web site may be left in limbo until it gets straightened out, which sometimes is never. Even if your free host owns their own servers, there can still be a big reliability problem if they haven’t devoted enough resources to maintenance and Internet security. Most free hosts are not going to pay for the expense of heavy duty, state-of-the-art firewall protection. You must be prepared for the possibility that you are vulnerable to hacker attacks that could easily bring down all of the sites they are hosting. And don’t rely on your free host to backup your site – make sure you have regular backups of everything you don’t want to lose.
When there is a problem, be prepared to be very patient for a response. Most free hosts only offer customer service and tech support via email. Keeping overhead low often means understaffing in these areas. Even if you have a serious problem such as your site being down for days or weeks, it’s highly unlikely that you would ever be able to speak to someone about it. If you want fast and efficient support, you’re much better off with a paid hosting provider. For this reason, only someone who is experienced and knowledgeable about the Web should consider free hosting since they are likely to need much less support. We don’t recommend free hosting for anyone who is new to the workings of the Internet.
When you take a closer look, the free hosting business is a gamble, whether you are the provider or the customers. In any industry there are honest business people and not so honest ones and it’s the same with free hosting. Unfortunately, even the honest ones can’t guarantee they’ll be able to live up to the promise of “free hosting for life” in a business so full of potential problems.

- click vào Telecharge le Wengo gì gì đó, để down software của nó về
- install xong, mở lên, nó sẽ có cái câu gì mà "Chưa có account à ? Cliquez ici" , click vào đó sẽ mở ra trang đăng ký account, chỉ cần điền dòng đầu tiên = email; dòng thứ 2 là username (vì login = email nên username gì cũng được). Xong xuống phía dưới có cái checkbox kiểu Accept terms and blah blah blah gì đó, check vào rồi click continue là xong
- Vào cái email vừa dùng đăng ký, check mail của Wengo vừa gửi, click cái link activate của nó là xong
- Login vào ở software, rồi click Appele un call gì gì đó (nghĩa là Place a call thì phẩy)
- Vì software của Pháp; coi như mình đang gọi từ Pháp ra, nên quay ra quốc tế, số đầu tiên sẽ là 00
Ví dụ; gọi về VN thì sẽ là : 00 84 4 8 222 222
Tips:
- mỗi account khi đăng ký xong, sẽ có 1€ trong tài khoản. Thường thì nếu bác đã gọi, nên nói cho xả láng hãy cụp máy. Vì sau khi nói xong, cái 1€ kia có thể sẽ biến thành -5€ -2€, lúc đấy thì sẽ ko gọi được nữa
- nếu account bị âm tiền ; chỉ cần đăng ký account khác, = email khác (mỗi email chỉ đc 1 account) là lại chiến tiếp
- nếu bác quay số, thấy nó lè nhè : Vu nơ pu vê pa com pô zi't xồng lờ nu mè rồ (Vous ne pu vê pas composition le numero) thì có nghĩa là 1, bác chưa activate account (hay) 2, tài khoản hết tiền
( VN cố định : 00 84 4 8222222
tít tít : 00 84 983 592 041 )
còn thích tự fone mình để test thì 00 1 716 xxxx xxxx gì gì đó
