MRI Data Compression Using a 3-D Discrete Wavelet transform

A low-power system that can be used to compress MRI data and for other medical applications is described. The system uses a low power 3-D DWT processor based on a centralized control unit architecture. The simulation results show the efficiency of the wavelet processor. The prototype processor consumes 0.5 W with total delay of 91.65 ns. The processor operates at a maximum frequency of 272 MHz. The prototype processor uses 16-bit adder, 16-bit Booth multiplier, and 1 kB cache with a maximum of 64-bit data bandwidth. Lower power has been achieved by using low-power building blocks and the minimal number of computational units with high throughput.

Branding – do you know who you are?

There is such a lot of talk going around about branding, but what exactly is your brand and how do you use it to help you reach more people and market your products or services?

Your brand is the core of your marketing, the central theme around your products and services.

Your brand is not your Logo or your Company Name, unless of course you are Microsoft or the Yellow Pages online directory.

For people to come and hire you, or buy from you in droves, your brand needs to be crystal clear, attractive, exciting and powerful. In fact your brand needs to be powerful enough to rouse your customers into action, and at the same time it needs to actively express you, what youíre about and your uniqueness.

Once you’re sure of your brand you also gain a tangible and easy way of talking to people about what you do. It makes it so much easier to do your marketing when you have it clear in your mind what it is youíre selling in the first place.

When you’re creating your brand you are creating a memorable marketing message that will inspire people to take action and choose you over your competitors.
Here are five useful tips to help you find your brand:

Your Brand Tip 1
Your brand is the core of what you do. What feelings or emotions does your business inspire in you and in your customers? Did you know that peoplesí decision to buy is based on emotions, not facts?

Your Brand Tip 2
Think about how you present yourself, not just on your website but when people see you, talk to you on the phone, or read your email. Is your marketing consistently saying what you want it to? Are people getting confusing messages from you, or is it clear from the start what you do?

Your Brand Tip 3
Think like your potential customer, try to get inside their head and see your products or services from their point of view. How do they experience what you do, and how does it make them feel?

Your Brand Tip 4
What is it you do that makes you stand out from the crowd? If you don’t think you do, then you need to think of a way that you can, because your brand should be somehow different from everyone else’s, its not enough to be just the same as others but better.

Your Brand Tip 5
What are your best abilities, do you know your greatest strengths? Choose an unbiased person, who knows you well, to help you decide what your top attributes are; your brand should be based around your unique strengths and abilities.

Ultimately, creating a strong, memorable, compelling and meaningful brand is essential for successful marketing, and something you can do with a bit of thought, and may be a bit of help from your (unbiased) friends.

A VLSI Architecture for Video Object Motion Estimation using a Novel 2-D Hierarchical Mesh

 

This paper proposes a novel hierarchical mesh-based video object model and a motion estimation architecture that generates a content-based video object representation. The 2-D mesh-based video object is represented using two layers: an alpha plane and a texture. The alpha plane consists of two layers: (1) a mesh layer and (2) a binary layer that defines the object boundary. The texture defines the object’s colors. A new hierarchical adaptive structured mesh represents the mesh layer. The proposed mesh is a coarse-to-fine hierarchical 2-D mesh that is formed by recursive triangulation of the initial coarse mesh geometry. The proposed technique reduces the mesh code size and captures the mesh dynamics.

The proposed motion estimation architecture generates a progressive mesh code and the motion vectors of the mesh nodes. The performance analysis for the proposed video object representation and the proposed motion estimation architecture shows that they are suitable for very low bit rate online mobile applications and the motion estimation architecture can be used as a building block for MPEG-4 codec.

Banner Advertising: How Does It Work?

So you are an internet marketer and you want to make money right? Or maybe you are just somebody with a product or service to sell that is looking for innovative ways to get your stuff in front of more customers eyes and increasing the size of your market share. Either way you have come to the right place to read about an excellent form of advertising called banner advertising that takes advantage of the wave of the futureóthe internet. The internet allows your market to instantly be any where in the world that there is a computer and that you can then ship your product or provide your service. Now some of the more traditional type services like doctors, plumbers, etc. will be limited by the geography naturally but this is still a great way to advertise in your area as more and more people are getting on the internet daily.

What is banner advertising you say? Well it is an ad that is placed on a website that is not related to the ad but preferably is one that lots of people will hit. It is an ad that usually is in some sort of image file and often contains typical words and pictures as well as animation and sound which are becoming popular ìhookingî techniques. The ad is usually short and wide or tall and narrow and this is why it is referred to as a banner. When a customer wants to see more they simply click on the banner and are taken via an embedded link to another page which is typically the sales page. If the product is something that you can purchase online or download it is done through this page. Otherwise it is just more exposure for the advertiser.

Another good question is why would the host website allow the ad to be on their page? Well just like any form of advertising the advertiser pays for time or in this case space. Most often with banner advertising the deal is worked out according to how many clickthroughs happen in a given amount of time. Usually the cost is five to ten cents per click.

How would I get my advertisement on a page? Well again just like other forms of advertising there are many ways to do it. You could personally contact the owner or operator of the site and work out a deal, or you could hire and advertising firm that does all of that work for you. Most often it is this second form that is used and these advertising companies will place the ad on multiple different sites and collect the fees, and paying the siteís owner or operator.

Banner Stand Exhibits

Banner Stands are a high impact, inexpensive and attractive medium of advertisement. They are usually found at exhibitions, trade shows, retail stores ñ just about anywhere the potential customer can be attracted by high wattage graphics.

The attractive thing about banner stands is that they are portable, flexible and easy to set up. There are different kinds of banner stands like retractable or rollup, pole, telescopic and others. The technology that enables the high quality of graphics and photos has added to the beauty of banners.

While organizing banner stands for exhibitions, there are many choices to deliberate on. For a portable trade show, the choice is between a fully customized exhibition and a portable exhibit.

The general opinion is that a portable is much better than a customized banner stand. For one, portable systems cost a fraction of a custom built one. The exhibition center built by portable is ready in a jiffy compared to the custom built systems.

Another advantage is that you can handle and test the system before using. It is flexible and can be used again and again. Also, portable systems are ready to pack and easy to transport.

Choosing the right banner stand may be considered care fully. Banner Stands can be divided into indoor and outdoor. Indoor exhibition banner stands are used for retail exhibitions and trade show conferences, indoor events and sales promotion. This category can be further divided into retractable and pole banner stands. Pole stands are cheap and strong. Roll up or retractable are easy to set up, with safe casing for graphics, and are easily portable.

Outdoor exhibition banner stands are suitable for outside use. They are weather proof, wind resistant and need outdoor resistant graphics.

Exhibition selling and advertising can energize the dullest of products with colorful and attractive banner stands. Banner stands exhibits are crucial for attracting potential customers.

Aida And Dagmar – Models For An Advertising Agency

An ad agency or advertising agency is a business or service dedicated to planning, handling and creating advertising for clients. These agencies are independent of clients and provide their skills and views to sell clientís services or products.

Advertising agencies can also manage branding strategies, marketing and sales promotions for its clients.

For an advertising agency, it is very important to realize that they can increase sales with their effort. Truly speaking, advertising agencies are minds working on the other side of the internet to increase sales. For a person working as an advertising agent, it is very important to know about the buyerís psychology.

Those who are working in an advertising agency should know about the various thought processes that go in the mind of a reader or a viewer, a potential buyer. This will definitely help to build your business better.

There are ample of theories to explain the process that goes in the buyerís mind when he/she goes to purchase anything.

The process is not the same for each buyer and it is sequential.

One of the popular features followed by ad agencies is AIDA.
AIDA is a acronym stands for:

A ñ Attention

I ñ Interest

D ñ Desire

A ñ Action

The AIDA model states that advertising agency should know how to draw attention of a buyer to get the customer interested by exhibiting its advantages, benefits and features. Interest is followed by desire. It is advertising agencyís duty to create a desire in a buyer to buy a specific product. All three steps of the AIDA policy will help you to stimulate the action towards the purchase of a product. AIDA theory guides and leads you to build a better advertising business. BIG Bís of advertising world have followed AIDA to generate good advertisement campaigns.

Another model called DAGMAR has now increasingly become more popular and comprehensive than AIDA. DAGMAR steps are more defined and easy to apply.

Term DAGMAR is an acronym for Defining Advertising Goals for Measured Advertising Results. According to DAGMAR, a sale must carry a potential customer through four stages:

I. Awareness

II. Comprehension

III. Conviction

IV. Action

Suppose you are having a service or product and your customer knows nothing about the product.
As your client is unaware of the product, the first step is to make him aware of your product by posting advertisement regarding your product on respective websites.

Comprehension is the second step of DAGMAR. Try to know the answers to these following questions.
a)What is your product about?
b)What are productís potential features and benefits of product?
c)What will your customer get from your product? And how?

Answers to all these questions will help you to get a potential customer.

Next stage is conviction and this is very important. Convince your customer by telling him the benefits of your product. After convincing, your next step starts i.e. action, which is not controlled by you. You have to depend on the customer. However, your previous actions will have a major role to play.

If you have been able to convince, the customer ad have answered him satisfactorily and then you will definitely be the winner of the day.

A Novel Current-Mode Instrumentation Amplifier Based on Operational Floating Current Conveyor,

 

This paper presents a novel current-mode instrumentation amplifier (CMIA) that utilizes an operational floating current conveyor (OFCC) as a basic building block. The OFCC, as a current-mode device, shows flexible properties with respect to other current- or voltage-mode circuits. The advantages of the proposed CMIA are threefold. First, it offers a higher differential gain and a bandwidth that is independent of gain, unlike a traditional voltage-mode instrumentation amplifier. Second, it maintains a high common-mode rejection ratio (CMRR) without requiring matched resistors, and finally, the proposed CMIA circuit offers a significant improvement in accuracy compared to other current-mode instrumentation amplifiers based on the current conveyor. The proposed CMIA has been analyzed, simulated, and experimentally tested. The experimental results verify that the proposed CMIA outperforms existing CMIAs in terms of the number of basic building blocks used, differential gain, and CMRR.

Avoid these advertising mistakes at all costs!

People have taken a number of approaches trying to do their own advertising ranging from silly all the way to insulting. These people choose there approach for various reasons. Some were ignorant about advertising and marketing while others were acting on incorrect information – usually in the form of cliches such as “sex sells.” If you’re in doubt, I can assure you that unless your business is in Nevada, sex does not sell. If you’re going to handle your own advertising, here are a few things to avoid:

Pictures that have nothing to do with your product or service – If your company is in the carpet cleaning business there is no reason to have a picture of a baby. No one is going to say “What a cute baby, I think I want this company to clean my carpets.” The same goes for pictures of sexy people (male or female) in provocative poses and little clothing.

Cheesy headlines – I actually saw an ad with a headline that said “We might be able to afford a bigger ad if you’d buy something from us.” Yes, this will probably get someone’s attention, but do you want to be remembered as the company that is having financial problems?

Illegible fonts – Most people will not take the time to decipher your ad when it is written in brush script, in which case, even the most persuasive copy is rendered useless. You want to use simple, clean fonts for headlines and body copy. Save the artistic fonts for accents and things of that nature.

Obiter.

By George Neilson.

 

THE claims of the legal profession to culture were cleverly belittled by Burns, when he made the New Brig of Ayr wax sarcastic over the town councillors of the burgh:—

“Men wha grew wise priggin owre hops an’ raisins,

Or gathered lib’ral views in Bonds and Seisins.”

Bonds and seisins are certainly not the happiest intellectual feeding ground. “I assure you,” said John Riddell, a great peerage antiquary, “that to spend one’s time in seeking for a name or a date in a bit of crabbed old writing does not improve the reasoning powers.” Riddell was a keen critic of Cosmo Innes, who subsequently had the happiness of passing the comment upon Riddell’s observation that “perhaps it is not in reasoning that Mr. Riddell excels.” Yet the annals of the law shew many splendid examples of the union of close textual study of manuscript, with an enlarged outlook on first principles and with keen critical insight. Perhaps Madox was a more permanently serviceable scholar than Selden. One can see from Coke’s margins, his infinite superiority to Bacon in exact knowledge at first hand of older English law. But when all is said, we could have done much better without Coke and Madox than without Bacon or Selden. It is delightful to be able to appeal to Chaucer for perhaps the most emphatic compliment to law, in respect to its capacity for literature, that it has ever received. Amongst all the Canterbury pilgrims, there was no weightier personage than the Man of Law:—

“Nowher so bisy a man as he ther nas,

And yet he semed bisier than he was.

In termes hadde he caas and domes alle

That from the tyme of King William were falle,

Therto he coude endyte and make a thing

Ther could no wight pinche at his wryting,

And every statut coude he pleyn by rote.”

Yet it was this learned and successful counsel, alone of the party, who knew the poet’s works through and through, and had the list of them at his finger-ends. Good Master Chaucer for this touch we offer hearty thanks! Was it in Herrick’s mind when he penned his fine tribute to Selden?

“I, who have favoured many, come to be

Graced, now at last, or glorified by thee.”

 

Wits and poets have had many hard things to say in jest and in earnest about the legal profession and its work. Herrick bracketed law and lawyers with diseases and doctors, in a fashion hinting that the relation of cause and effect existed between both pairs:—

“As many laws and lawyers do express,

Nought but a kingdom’s ill-affectedness.

Even so those streets and houses do but show

Store of diseases where physicians flow.”

 

It was an old story this linking of the practitioners of law and medicine in one yoke of abuse. The reason given for both categories in early satire is sufficiently curious. It was because they took fees! Walter Map declared the Cistercian creed to be that no man could serve God without mammon. Ancient satire equally objected to the service of man, either legally or medically, under these conditions. “The Romaunt of the Rose” has the traditional refrain of other strictures in verse, when it declares that

“Physiciens and advocates,

Gon right by the same yates,yates, gates

They selle hir science for winning.winning, gain

  • ···

For they nil in no maner greeno kind of good will

Do right nought for charitee.”

 

The same idea, precisely, finds voice in the poem attributed to Walter Map, wherein the doctor and the lawyer come together under the lash, because no hope can be based upon either of them unless there be money in the case. “But if the marvellous man see coin, the very worst disease is quite curable, the very falsest cause just, praiseworthy, pious, true, and pleasing to God.” Perhaps these ancient sarcasms were keener on the leech than the lawyer. “The Romaunt of the Rose” goes so far as to say that if the physicians had their way of it,

“Everiche man shulde be seke,

And though they dye, they set not a leke

After: whan they the gold have take

Ful litel care for hem they make.

They wolde that fourty were seke at onis!

Ye, two hundred in flesh and bonis!

And yit two thousand as I gesse

For to encresen her richesse.”

 

No doubt the men of medicine would have been much more vulnerable on another line, for it was no satirist but a learned medical professor, Arnauld de Villeneuve, who, in the beginning of the fourteenth century, advised his students as follows:—“The seventh precaution,” said he, “is of a general application. Suppose that you cannot understand the case of your patient, say to him with assurance that he hath an obstruction of the liver.” No legal professor surely was ever guilty of the indiscretion of saying such a thing as this!

 

The ineradicable public prejudice against legal charges as flagrantly exorbitant is only a modified form of an older idea exemplified above that lawyers should have no fees at all. And as to this day the plain man has never fully reconciled himself to the doctrine that the lawyer is only an agent, and not called upon to sit in the first instance in judgment on his client, so in the past the professional defence of a criminal appeared a very venal transaction.

“Thow I have a man i-slawe,

And forfetyd the kynges lawe

I sal fyndyn a man of lawe

Wyl takyn myn peny and let me goo.”

 

How reprehensible a thing to take fees was long reckoned admits of curious illustration. “Before the end of the thirteenth century,” says that never-failing authority, Pollock and Maitland’s “History of English Law,” “there already exists a legal profession, a class of men who make money by representing litigants before the courts and by giving legal advice. The evolution of this class has been slow, for it has been withstood by certain ancient principles.” Amongst these retarding influences lay the half-religious scruple about the propriety of payment—men as usual swallowing the camel first and straining at the gnat afterwards. Of course the subject had to be illuminated by monkish tales and death-bed repentances. There was, according to the Carlisle friar who penned the “The Chronicle of Lanercost,”—writing under the year 1288,—a young clerk in the diocese of Glasgow, whose mind “was given rather to the court of the rich than to the cure of souls. He was called Adam Urri, and was laically learned in the laic laws, disregarding the commands of God against the Praecorialia [so in the printed text, but, query, Praetorialia?] of Ulpian. He used the statutes of the Emperor in litigating causes, for payment of money. But when he had grown old and famous in this his wickedness, and was striving by his astuteness to entangle the affairs of a poor little widow, the divine mercy laid hold on him, assailing his body with sudden infirmity, and bringing his mind to plead (enarraret) more for another life.” Condemning utterly the lawyer’s court, he turned over a new leaf, predicted the day of his own death, and died punctually conform to the prophecy, leaving an example unctuously used by the friar to teach future generations “how wide was the gulf betwixt the service of God and the vanity of this world.” We shall not be far wrong in regarding, as of more historic interest, the indication of the immorality of fees, and the important reference to Ulpian as an authority in the forum causidicorum of thirteenth century Scotland.

 

Amongst the amiable conceptions of the middle age was the notion that the Evil One often manifested a particular zeal against sin. He was regarded with a different eye from that with which we regard him, and he rewarded faith with actual appearances such as only spiritualists can now-a-days command. Some of them were not very engaging, however praiseworthy may have been their object and occasion. Simeon of Durham, an eminently respectable contemporary author, wrote of the death of King William Rufus in the year 1100 that the popular voice considered the wandering flight of Tyrell’s arrow a token of the “virtue and vengeance of God.” And he added that about that time the Devil had frequently shewn himself in the woods “and no wonder, because in those days law and justice were all but silent.” The logic of this because, not apparent on the surface, becomes less obscure when it is remembered that in the mediæval devil the character of Arch-Enemy is so much subordinated to that of Arch-Avenger.

 

The direct relation of not only the Saints but of the Deity itself to human affairs was a conception so clear to the mediæval mind that it saw nothing irreverent in a title deed being taken in the Supreme name, or in marshalling “Deus Omnipotens” at the head of the list of witnesses to a charter. This anthropomorphic practice gave occasion to one of the sharpest of Walter Map’s jokes against the Cistercians. Three abbots of that order petitioning on behalf of one of their number and his abbey for the restoration of certain lands by King Henry II. as having been injuriously taken away from the claimant’s abbey, represented to the King in his court that for God’s sake he ought to cause the lands to be restored and they assured him and gave him God himself as their guarantor (fidejussorem) that if he did, God would greatly increase his honour upon earth. King Henry found it difficult to resist the appeal thus made to him but called the Archdeacon Walter Map to advise. This he did well-knowing that this counsellor did not love the Cistercians, and that he might thus find a creditable way out of a tight corner. The Archdeacon was equal to the occasion. “My lord,” said he to the King, “they offer you a guarantor; you should hear their guarantor speak for himself.” “By the eyes of God,” replied Henry, “it is just and conform to reason that guarantors themselves should be heard upon the matter of their guarantee.” Then rising with a gentle smile (not a grin, expressly says Giraldus Cambrensis) the shrewd monarch retired leaving the disappointed abbots covered with confusion.

 

Of the many ties between literature and law, one, not by any means the least interesting on the list, is the quantity of legal citations, phrases, metaphors and analogies which got swept into the wide nets of the poets. Amongst such scraps there are few so successful and still fewer so pathetic as one in which a metrical historian, drawing near the close, both of his days and his chronicle, figured himself as summoned on short induciæ at the instance of Old Age to appear at a court to answer serious charges, where no help was for him save through grace and the Virgin as his advocate.

Androw of Wyntoun’s verse it must be owned was verse on the plane of a notary public, and oft the common form of legal writ supplied sorrily enough the deficiencies of his imagination. But here for once the simple dignity of the thought bore him up and carried him through.
