Tiny Robot Hand Could Revolutionise In Utero Surgery

Welcome to the new world technology where a tiny robot hand could revolutionise in utero surgery. Almost A$18 million has been invested into building a tiny surgical hand that can operate on foetuses or deliver stem cells to damaged organs. 

The minuscule device would also provide 3D images of the foetus while it’s still in the womb.The ambitious projects aims to transform the way scientists treat congenital conditions such as spina bifida, a condition that in its most serious form affects around one in 1,000 babies and causes a baby to be born with an underdeveloped spine and neurological problems.The robot hand is still only in the research stage at University College London and KU Leuven in Belgium, The Guardian reports, but the Wellcome Trust-funded project has the potential to lead to less invasive surgical technologies that put mother and baby at less risk.

             

Right now, doctors treat spina bifada by “patching” the gap in the foetuses' spines. But currently they’re only able to perform surgery once the unborn baby is at least 26 weeks old, at which point considerable damage may have already been done to the child’s developing brain. They also have to open up the mother’s abdomen and uterus, causing a significant risk of premature birth.

The new hand works like tiny pincers, and it’s envisioned it would be inserted into the womb without needing to open up the mother, and then would use its 3D camera to guide doctors throughout the surgery.

Possessiveness: Builds or ruins a relation ??

Why we think too much? If I say….because we care the most about the special one. It is all right, but sometimes it causes the possessiveness.

Possessiveness: Builds or ruins a relation ??

It all depends on your partner because sometime people like it when their spouse is possessive about them. For them, it is a proof of true love and care, while on other side some partner do not like it because they feel lack of freedom and suffocation by their possessiveness.

Now the question is that.....Upto what certain level we should maintain the possessiveness to built a better relationship. It all depends upon the understanding between them.

Possessiveness is not a crime but you have to also remember that excess of anything is bad…!!

Optimization Technique

Introduction:

Optimization is the technique of obtaining best results under given circumstances.The 'Optimization Techniques' also known as 'Mathematical Programming Techniques' are the methods which gives which gives the best results, under the given conditions, to the given programming problems.

History of Optimization:

The main origin is the second world war. At that time the scientists of England were asked to study the strategic and tactical problems related to air and land defence of the country.Due to the limited resources, it was necessary to make utilization of them. Historically, the first term for optimization was "linear programming", which was due to George B. Dantzig, although much of the theory had been introduced by Leonid Kantorovich in 1939. Dantzig published the Simplex algorithm in 1947, and John von Neumann developed the theory of duality in the same year.The term, programming, in this context does not refer to computer programming. Rather, the term comes from the use of program by the United States military to refer to proposed training and logistics schedules, which were the problems Dantzig studied at that time

       

Computational Optimization Problem:

To solve problems, researchers may use algorithms that terminate in a finite number of steps,or iterative methods that converge to a solution 

1. Optimization algorithms

Simplex algorithm of George Dantzig, designed for linear programming. Extensions of the simplex algorithm, designed for quadratic programming and for linear-fractional programming.Variants of the simplex algorithm that are especially suited for network optimization. 

2. Iterative methods

The iterative methods used to solve problems of nonlinear programming differ according to whether they evaluate Hessians, gradients, or only function values. While evaluating Hessians (H) and gradients (G) improves the rate of convergence, for functions for which these quantities exist and vary sufficiently smoothly, such evaluations increase the computational complexity (or computational cost) of each iteration. In some cases, the computational complexity may be excessively high. 

Methods that evaluate Hessians (or approximate Hessians, using finite differences):
1.Newton's method
2.Sequential quadratic programming: A Newton-based method for small-medium scale constrained problems. Some versions can handle large-dimensional problems. 

Methods that evaluate gradients or approximate gradients using finite differences (or even subgradients): 

1.Quasi-Newton methods: Iterative methods for medium-large problems (e.g. N<1000). 

2.Conjugate gradient methods: Iterative methods for large problems. (In theory, these methods terminate in a finite number of steps with quadratic objective functions, but this finite termination is not observed in practice on finite–precision computers.) 

3.Interior point methods: This is a large class of methods for constrained optimization. Some interior-point methods use only (sub)gradient information, and others of which require the evaluation of Hessians. 

                        
Applications:
1.In bringing out new design
2.Planning of maintenance and replacement of equipment to reduce operating cost.
3.Controlling the idle and waiting times and queueing in production lines to reduce the costs .
4.Design of control system.
5.Inventory control.
6.Travelling salesman problem.

Introduction to Embedded System

It is really fantastic that today science has developed a lot. Today we can do everything in a very short period apart from our imagination.The technological world of today runs on a hidden technology called as Embedded Systems.Embedded systems are the name given to the chips within our mobile phones, modems and set-top boxes. These chips are the opposite of the normal chips that are deployed in our personal computers like laptops and desktops.

History:

In the earliest years of computers in the 1930–40s, computers were sometimes dedicated to a single task, but were far too large and expensive for most kinds of tasks performed by embedded computers of today. Over time however, the concept of programmable controllers evolved from traditional electromechanical sequencers, via solid state devices, to the use of computer technology.

One of the very first recognizably modern embedded systems was the Apollo Guidance Computers, developed by Charles Stark at the MIT Instrumentation Laboratory. At the project's inception, the Apollo guidance computer was considered the riskiest item in the Apollo project as it employed the then newly developed monolithic integrated circuits to reduce the size and weight.Since these early applications in the 1960s, embedded systems have come down in price and there has been a dramatic rise in processing power and functionality. The first microprocessor for example, the Intel 4004 was designed for calculators and other small systems but still required external memory and support chips. Nowadays microcontrollers are cheap and readily available for hobbyists, with large online communities around certain processors.

Growth Of Android In Embedded System:

Linux has continuously grown in the embedded systems market for over a decade, gaining market share from proprietary operating systems. The proliferation of embedded devices, the explosion of open source development, the inherent hardware support, the incredible networking capabilities and the royalty-free economic model have all helped propel use of the Linux kernel into one of the best choices for the design of new embedded systems. While the success of Linux in the embedded market can not be denied, its notoriety was once confined to mostly technical professionals. That changed in 2008 with Google’s release of the Android mobile phone operating system, based on the Linux kernel. Thus began the tremendous growth of Linux in the consumer world, with over one million Android devices being activated every day in 2012 and predictions of total Android devices shipped reaching one billion in 2013.
Embedded System In Automobiles:

An embedded system is defined as a computer system with a fanatical function surrounded by a larger mechanical or electrical system, frequently with real time computing constriction.Nearly each and every car that ways off the manufacture line nowadays take advantage and use of embedded technology in one or the other way. The majority of the embedded systems in automobiles are jagged in nature because nearly every system is made up of a single chip.

Embedded system facilitates them to fit easily under the confined lid of a car. It can be used to execute features starting from modification of the deferral to suit road conditions and the petroleum component in the fuel to anti lock braking systems and security systems. It can convert a dream into reality by developing a drive less vehicle control, as big and main automobile producers are already occupied in work on this philosophy. Ford has acknowledged a technology with the name called Adaptive Cruise Control. It lets cars to maintain a distance which is safe on busy roads and highways from other vehicles. The speed and distance of the car from other vehicles can be easily and quickly set by the driver with ease. The ACC computer inbuilt regularly controls the choke and brakes of the car. 

Future Scope of Embedded System:

Embedded systems market is expected to grow at an average annual growth rate (AAGR) of 13% over the period, rising from $32 billion in 1998 to nearly $67 billion in 2004.Software for embedded applications, which includes realtime operating systems and portable operating systems, will see the second highest growth, with an AAGR of over 16% through the period. Market heavyweights Microsoft and Sun have entered the embedded systems marketplace, their Windows CE and Java offerings, respectively.

Embedded processors, the largest segment in terms of revenue, will grow at 11.2% on average per year. Embedded systems are designed to do some specific task, rather than be a general-purpose computer for multiple tasks. Some also have real time performance constraints that must be met, for reasons such as safety and usability; others may have low or no performance requirements, allowing the system hardware to be simplified to reduce costs.

My First Love...!!

You cannot compare any love to your first love, because when you loved, you loved with innocence and you risked without fear. Because you didn't know what fear was, the thought of heartache was lacking in your daily. When you first loved, you loved purely, without doubt and hesitation. You loved, uneducated and unaware. You loved without knowing what love was. And it would be awfully unfair to compare any love to your first love, because from then and always on, you will search for that familiar voice in static, emotion in white noise, and magic in reality. And reality is, you'll always have that void and it won't ever be filled because it's there and it exists from experience. And it won't be until you realize that, do you finally understand that falling in love again is and could be far greater because you are so lucky if love find you again, even if it has to force itself into the little crevice you try to fill with needless other unnecessary things. Because this time, you are aware, educated and knowing. Because if you really do ever fall in love again, you can differentiate between real and lust, and if it is real, you better know how to love and what  is to be loved.

RollTop Technology

Its so boring to handle the heavy laptops…from one place to another with quite difficulty. But  with the rising era the Germany's Orkin Design proposes rolling up both devices into one ultra-portable package.  

Introduction:

Let us get introduced with the new latest technology which is ROLLTOP TECHNOLOGY. Notebooks and tablets already offer pretty convenient computing on-the-go solutions. The Rolltop concept will take advantage of advances in flexible OLED and touchscreen technologies to create a cylinder-shaped laptop computer that can be rolled out to form a notebook, a tablet, or display monitor. Besides leading to an extreme the concept of  portable computer, the rolltop succeded in reuniting two of the largest consumer dreams of geek on calls: netbooks , objects of desire of any user who want to stay connected and up to date with new technology and tablets, even more famous after rumors of the launch of Apple Tablet.

How to use ??

Rather than carry around a notebook in a laptop bag, full to the brim with all manner of cables, the Rolltop concept proposes bringing everything together in a flat panel display that's wrapped around a central cylinder. The top of the column detaches and acts as a power plug while the carry strap doubles as a power cord (presumably some sort of battery technology is also included, although this has not been mentioned). The central column also contains speakers, a camera, USB ports, and a LAN port.

The main goal of this technology is to combine the laptop, monitor and the graphic tablet into one  gadget and avoid additional accessories. The Rolltop does not have a CD/DVD reader or floppy disc because they are obsolete.

After unlocking the catch, the user would roll out the Rolltop display like a mat and then either leave it flat for 17-inch tablet computing, or raise one end up for something resembling a notebook. The lower part of the screen is then used for keying on a virtual, onscreen keyboard while the upper part becomes a 13-inch display for viewing content. A pull-out support at the back also allows the flattened device to be used as a monitor-like display, and a stylus pen has been incorporated into the body of the panel. To close the package dream of consumption, it also lets us to view videos, or photos like a portable television. The screen has a support on the back. With this you can leave it up, and watch a movie while waiting for the email from your boss.

When rolled up, Rolltop will be 11 inches (28 cm) long and have a 3.26-inch (8.3-cm) diameter – and that's about all we can tell you. As it's a concept designed to be built in the future, some of the technology kinks are still being worked on, but Orkin has stated its intention to see this design through to an actual, real-world product. There are, of course, quite a number of technical hurdles to overcome before that happens and unfortunately the designers do little to shed light on how such difficulties will be dealt with, leaving us to speculate.

Future scope:

It requires no great stretch of the imagination to visualize the various technologies already used in dual-screen notebooks, all-in-one computers and cutting edge tablets being incorporated into the Rolltop. However, details on how the internal components like processors, memory, storage and graphics cards will be dealt with have not been forthcoming, so it looks like we're just going to have to wait until there is more substance to this project .So we can say that the Rolltop technology is a great boon to the present as well as the coming generation and may be in future it the recent developments in bendy screen technology might also make this device a current possibility.

Smart Grid Technology - Today's challenge

The power grid today:
The North American power grid has been described as the “supreme engineering achievement of the 20th century”. It is a vast electricity delivery infrastructure comprising transmission and distribution networks spanning the continental United States, connecting electricity generation to the consumers of electric power. The grid contains over 200,000 miles of high-voltage (over 230 kV) transmission lines and more than 6 million miles of distribution lines that deliver power to over 100 million customers and 283 million people.

However, the power grid today is aging, congested and increasingly seen as incapable of meeting the future energy needs of an Information Economy. As businesses have become dependent on electronic devices for information exchange and commerce, the use of electricity as an energy source has grown relative to fuels, currently representing 40% of overall energy consumption in the US. The importance of electricity as a driver of economic growth can be gauged from the fact that electricity sales trend with the growth of the GDP more closely than other energy sources, as shown in the following graphic. Assembled over the last century, the power grid was not designed to support the extensive coordination of generation, transmission and distribution that is called for today and it faces stresses and challenges that are creating drivers for the modernization and restructuring of the grid to accommodate the needs and requirements of a 21st century economy.

Drivers for modernization of the power grid:

New challenges and drivers: The grid faces new challenges and stresses that will put at risk its ability to reliably deliver power to an economy that is increasingly dependent on electricity:

-- Growth in demand: 

Peak demand is forecasted to grow by 18% over the next 10 years, driven by economic growth and the evolution towards an Information Economy. Electricity’s growing importance as a source of energy supply to the economy is reflected in the fact that over 40% of energy consumption in the US is used to produce electricity, up from 10% in 1940 and 25% in 1970.

-- Constraints on capacity expansion: 
Simultaneously, generation capacity is forecasted to hit critical reserve limits within the next 10 years for most of the US and new transmission and generation projects are not expected to be completed in time to avoid hitting capacity issues.
-- Shifts in generation sources: 
The shift towards newer renewable and distributed energy generation sources such as wind and solar that can be variable and located far from demand present new challenges of control and coordination for the power grid. Co-generation from non-traditional sources will be mandated in some places requiring two-way control and monitoring at non-utility owned facilities.
-- Transmission congestion: 
Investments in the transmission infrastructure have not kept pace with the growth in demand, resulting in heavier utilization, frequent congestion, increased transmission losses and increased risk of catastrophic failures. Costs of building transmission lines and obtaining rights-of-way have increased dramatically and construction timelines will continue to increase.
-- Distribution: 
Increased use of information technologies, computers and consumer electronics by customers has resulted in lowered tolerances to outages and power quality disturbances. A growing interest in distributed generation and electric storage devices at the edge is adding new requirements for interconnection and safe operation of electric distribution systems. Emerging trends such as plug-in hybrid electric vehicles (PHEVs) promise to put still more stress on the already-strained generation, transmission and distribution systems.
-- Demand management: 
Utilities see an increasing need for demand management as a way to improve operating costs, enhance reliability and to potentially defer construction of generation and transmission capacity. The need to regulate and control the demand side through demand response and time-based rates — both of which require two-way communications capabilities down to the individual meter — adds another layer of complexity to the grid.
-- Regulatory policy: 
Federal governments and many states are passing energy efficiency mandates and PUCs are enabling utilities to recover investments in upgrading the grid infrastructure and implementing measures such as demand response.
-- Environmental impact: 
Electric power generation accounts for approximately 25% of the world’s carbon dioxide emissions and new carbon regulations will have a major impact on the industry. Building new transmission lines will encounter stricter environmental impact requirements than ever before.

The vision of a smart grid:
A growing recognition of the need to modernize the grid to meet tomorrow’s challenges has found articulation in the vision of a smart grid. Multiple industry and research groups have created architectural blueprints for the evolution of today’s power grid into a smart grid that share several common features.

The smart grid, as it is conceived today, will offer several benefits to utilities and consumers:

—It will provide utilities the ability to monitor and manage their power delivery down to the home or business in real time
—Utilities can offer multiple rate structures to manage demand peaks and offer demand management services to encourage efficiency
—It will allow utilities to manage outages more effectively by reducing their occurrence through better monitoring and control of the grid and by reducing the impact of outages through more efficient and early problem isolation, using techniques such as automatic load-shedding and islanding as well as faster recovery procedures. Power outages are estimated to impose an economic cost of upwards of $100 billion every year and, in an increasingly interconnected Information Economy, it is imperative to reduce the frequency and the impacts of outages as well as of disturbances in power quality.
—It will allow utilities to delay the construction of new plants and transmission lines and better manage their carbon output through implementing measures such as demand response and time-based rates to more actively manage load.
—It will allow utilities to provide real-time information to their customers and to utility workers in the field, resulting in operational efficiencies and more reliable service.
—It will allow utilities to more proactively manage the integration of clean energy technologies into the grid to maximize their environmental benefits and operational value.

The smart grid is envisioned to offer these benefits by enabling and enhancing a broad range of utility applications, including Advanced Metering Infrastructure (AMI), outage management, demand management, distribution automation, substation security and mobile workforce connectivity.

From a technological perspective, the essence of the smart grid vision is “the digital control of the power delivery network and two-way communication with customers and market participants” through the realization of “a fully-automated power delivery network that can ensure a two-way flow of electricity and information between the power plants and appliances and all points in between.”9 The central idea behind the smart grid vision is that information technology can revolutionize the generation and delivery of electricity just as it has transformed other aspects of business. It is an ambitious but attainable vision that comprises distributed intelligence, broadband communications and automated control systems – building on commercially-proven technologies that exist today.
-- Distributed intelligence: 
This builds on advanced sensors with processing and communications capabilities built into every element of the grid (switches, transformers, substations, distribution lines, etc.) as well as advanced metering endpoints and smart appliances in the home. The distributed intelligence will enable real-time monitoring, coordination and control. For example, advanced meters with wide-area wireless communications capabilities can report back interval data to a meter data management system several times a day, allowing for real-time demand response coordination. Advanced sensors can be used to monitor the health of the grid in real-time and respond (perhaps autonomously, without central coordination) to avert system-wide failures and outages.
--Broadband communications: 
A broadband communications infrastructure is key to enabling comprehensive system-wide monitoring and coordination to enable applications as diverse as distribution automation, demand response, outage management and power quality monitoring. These applications include requirements for low latency, high bandwidth and QoS prioritization that require a broadband network. The communications infrastructure would tie together the meter end-points, the utility mobile workforce, advanced sensors and control centers into a single integrated network. SCADA systems employed today do not sense or control nearly enough of the components of the grid and there is a need for reliable, up-to-date information to feed state estimation, contingency analysis and other procedures. Furthermore, the communications links in use today are proprietary (non-standard) and slow (high latency, low capacity). However, standards-based technologies exist today to enable multiple low-latency high-data-rate, two-way communications links among all the nodes in the network, extending from the control centers down to the substations and all the way down to individual meters.
--Automated control systems: 
The third major element consists of centralized software tools and algorithms for self-re configuring and adapting the grid, executing protocols for demand response and automatic load-shedding, and promoting better coordination within and between utilities.

Our Happiness lies in the Happiness of other People...:) :)

Once a group of 500 people were attending a seminar. Suddenly the speaker stopped and decided to do a group activity. He started giving each person a balloon. Each person was then asked to write their name on it using a marker pen. Then all the balloons were collected and put in another room.

The people were then let into that room and asked to find the balloon which had their name written on it within 5 minutes. Everyone was frantically searching for their name, colliding with each other, pushing around others and there was utter chaos.

At the end of 5 minutes no one could find their own balloon. Then, the speaker  asked each person to randomly collect a balloon and give it to the person whose name was written on it. Within minutes everyone had their own balloon.

The speaker then began, "This is happening in our lives. Everyone is frantically looking for happiness all around, not knowing where it is.

Our happiness lies in the happiness of other people. Give them their happiness; you will get your own happiness. And this is the purpose of human life...the pursuit happiness."

Fight Against CANCER…!!!

As we are used to the very old quotation that “ Health Is Wealth” but do we really follow it. We human beings are quite busy with our lifestyle , we have no time to pay attention over our health. Two of the topics are always tend to be most interested in theses modern days are “Health” and “wealth” and for appropriate reason, of course, as health and wealth are two of the most crucial aspect to acquiring a highly delightful life. However, one thing, which quite a few people actually feel, is just how exactly “health” correlates with “wealth”; when you are healthy, you will certainly get a much time to attain greater wealth also.

Fine health and fitness is really a great asset. It is the genuine treasure of existence, essentially the most valuable thing of person. In case a person loss his health and fitness, the entire world failures all of its charms for him. The unawareness towards health leads to various diseases.

Now in the present  scenario, among the various diseases the gigantic name CANCER has become a very common disease. Cancer is a class of diseases characterized by out-of-control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected.

Causes:

Cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumors (except in the case of leukemia where cancer prohibits normal blood function by abnormal cell division in the blood stream). Tumors that stay in one spot and demonstrate limited growth are generally considered to be benign. scientists reported in Nature Communications (October 2012 issue) that they have discovered an important clue as to why cancer cells spread.  Certain molecular interactions between cells and the scaffolding that holds them in place (extracellular matrix) cause them to become unstuck at the original tumor site, they become dislodged, move on and then reattach themselves at a new site. The researchers say this discovery is important because cancer mortality is mainly due to metastatic tumors, those that grow from cells that have traveled from their original site to another part of the body. Only 10% of cancer deaths are caused by the primary tumors. Cancer is ultimately the result of cells that uncontrollably grow and do not die. Normal cells in the body follow an orderly path of growth, division, and death. Programmed cell death is called apoptosis, and when this process breaks down, cancer begins to form. Unlike regular cells, cancer cells do not experience programmatic death and instead continue to grow and divide. This leads to a mass of abnormal cells that grows out of control.

Solutions:

There are many ways to minimise the risk of cancer. First of all we should be be as lean as possible without being underweight,  physically activeness is required in everyday life, consumption of food and drink high in fat, sugar and calories should be limited, eating of  processed meats and limit red meat should be limited, alcohol consumption should be avoided, cancer survivors should get specialist nutritional advice.

So an effective wealth of health can be acquired in many means. It requires routine workouts, very good foodstuff, excellent thought processes, and hygiene. Hence, it is, apparent that overall health is a lot like an excellent cherish and yes it should be protected jealously. You have to go ahead and take ideal proper care of our systems. Just because happiness of life is rely on wholesome body. Critically challenge with the machine of your entire body means death-an end to life itself. A person who owns sound health should indeed be an incredibly wealthy person.

What Technology Speaks…!!

From Issac Newton to Albert Einstein ,Michael faraday to John Dalton and many more names related to past, present and future of world science…. From all these names we have learned only one thing that “ Try and Try hard until you succeed in your goals….” 

Collaboration of science with the developing human minds has always resulted in bringing a new technology with improved efficiency and better functionality. Pretty soon we'll have robots in our society, you're going to have a lot of automated processes that used to be done by people - this is happening. Society and technology is changing so fast, and the impact of the change on society and technology is global, not local.

All this technology, all the computer games and the iPhones... nobody will sit for art anymore. What a dismaying state of humanity.

Hence we the young scientists surely have a special responsibilities on our shoulders. It is our idea that form the basis of new technology. We should not be indifferent to the fruits of our ideas. We should forgo experiments that are risky or unethical and do a better job to make a better world…!!
