Magnetic Nanoparticles

2010-10-08T21:39:00.000-07:00

When my friend mentioned that he did an experiment with Magnetic Nanoparticles recently, I was curious about it. He briefly introduced me with them. Then we discussed the Physics behind it. Next, I searched the use of Magnetic Nanoparticles in YouTube and I got the following video that explains how Magnetic Nanoparticles is used to treat cancer. It's very interesting :

A Chinese concept for Non-Stop Trains, wow !

2010-06-08T12:46:00.000-07:00

I liked this idea. Watch it carefully. Basically, the train is made up of the regular train compartment and also the ‘boarding/unboarding’ compartment. Passengers may board the ‘boarding’ compartment while waiting for the train to arrive at the station. As the train arrives, it slows down and is located beneath the ‘boarding’ platform, latching on and begining to carry the now boarded

Power of punctuation

2010-05-24T06:17:00.000-07:00

Punctuation plays a great role to give meaning for a sentence. Here is an example from Wikipedia: Sentence1: "woman, without her man, is nothing" Sentence2: "woman: without her, man is nothing" Both of these sentences have the same words. However, the meanings of these two sentences are completely different ! What makes the meaning different ? The answer is the punctuations ! Thus, they are

Baghban - A good hindi movie

2010-05-23T06:27:00.000-07:00

Recently I watched Baghban, a hindi movie released in 2003 (available here). Although the movie is 3 hours long, I didn't get bored even a single second ! Truely a great movie ! Clearly sends a good message... it is all about a couple who spend everything for their 4 sons but ultimately gets nothing (no respect) from them, after the retirement of the husband. The man who helped you take your

Voice Translation

2010-05-22T15:13:00.000-07:00

First time when I came to France, I was thinking of some devices to translate my voice into French simply because French (and only French) is everywhere from restaurant to department ... ... umm. I had neither a good knowledge of French nor such devices. Thus, I would have bought some devices that recognize one's voice and play into target languages if they were available. I'm aware of the

Devices make people feel lonely

2010-05-04T06:10:00.000-07:00

I was reading an article about text only friend, a good article indeed. I liked some of the points the writer mentioned in his article. One of them was:"But the tragic, isolating thing is that we reach for our devices because we don’t want to seem lonely — which is causing us to avoid our peers and actually be lonely."We say that we feel lonely if we don't have phones, laptops or PDAs. And we use

Writing Emails in French ?

I receive many emails each day. No doubt, they are 99% French ones. Unlike at the beginning, I now understand French emails (at least I can guess the meaning :) ). In the worst case, I use online translation services. These days, I write emails in French too. I remember the hardest day when I tried to write email in French to get my transcript from Telecom SudParis. It was little bit urgent. As

For example, if a great politician dies, people generate content exponentially. Providing relevant information in real time is not so easy. Here I'm listing some of the points that I liked in the article. Now a delay of

Text Normalizer - Dealing with ascents

2010-03-30T06:20:00.000-07:00

I had to sort French texts in alphabetical order. It was not as simple as we compare English strings because we must deal with the French ascents such as é and à.If we don't process anything and use the simple string comparison function, we get équipement after zebra. However, we need équipement between words starting from 'd' and 'f' i.e. we want équipement as if it were equipement. In order to

XML Namespace: Attributes are a little different

2010-02-25T03:32:00.000-08:00

An attribute can appear in a different namespace than the element that contains it. For example, has an attribute that is not from the movie namespace. If an attribute name has a prefix, its name is in the namespace indicated by the prefix. However, if an attribute name has no prefix, it has no namespace. This is true even when the default namespace has been assigned.

Finding 'a word' using Regular Expression

2010-01-28T02:36:00.000-08:00

We frequently need to test where a word (rather than pattern) exists in other string or not. To illustrate more, consider the following two strings: String1: This fact is very important to understand. String2: port Now two interesting cases arise: Find whether pattern "port" appears in String1: In this case the regular expression would be: String regExp=".*"+ String2 +".*"; Clearly, we don't

Keep your eyes on the destination, not on the road

2009-11-12T01:05:00.000-08:00

This is a very crucial adage. It says that we should be very attentive towards our goal. To reach at the destination, there might be many ways some of which may be shorter than others. However, it is not important to look at these roads because the ultimate thing is whether one reached at destination or not. No matter which way he takes, he is not successful unless he gets what he wants.

Guns can do nothing; barriers can do nothing - they just intimidate people for days or may be for few years; they may claim few lives. No weapons are needed to counter-attack junta and dictators. Just need to make people aware of their RIGHTS and FREEDOMS. Look at the "Fall of Berlin Wall" in 9th Nov 1989. Anybody who has visited Berlin must have a bag of words at this moment: November 9, 1989;

2009-08-31T03:25:00.000-07:00

Introduction:Wikipedia defines An n-gram as: a subsequence of n items from a given sequence. The items in question can be phonemes, syllables, letters, words or base pairs according to the application. An n-gram of size 1 is referred to as a "unigram"; size 2 is a "bigram" (or, less commonly, a "digram"); size 3 is a "trigram"; and size 4 or more is simply called an "n-gram". Usagesn-grams are

I found many interesting methods to solve mathematical problems. In this blog, I'll post some of them.How to find square of a number quickly ? Multiplying two numbers will be easy if one of them is a multiple of 10. There is also a high probability that a person knows the squares of small numbers by heart. If we incorporate these two ideas, we can get a quicker solution to get the square of a

Using Multiple Search Engines

2009-08-28T06:56:00.000-07:00

I just found a useful website. It is really useful because it saves user's time by presenting the results of a query from two different search engines. In other words, with same input effort, one can get results from two search engines. As an example, if I want to search NEPAL in Google, I would be happy if I can get the results for NEPAL from other search engine e.g. Yahoo, on side-by-side. This

Using TreeTagger

2009-08-27T09:55:00.000-07:00

I recently used TreeTagger to get the part-of-speech (POS) of English and French texts. As mentioned in its original website [1], TreeTagger is a language independent tool used for annotating text with part-of-speech and lemma information.Installation is pretty easy. One just needs to follow the instructions given in the website. After the installation it will tell you something like : You should

Lexical Similarity Measure

2009-08-27T05:43:00.000-07:00

My last post described the Levenshtein's algorithm for finding the differences between two sequences which does so by means of "edit distance" metric. Recently, I read an algorithm that utilizes the same metric to calculate the lexical similarity measure between two strings Li and Lj:SM(Li, Lj ) := max(0 , (min( |Li|, |Lj| ) - ed(Li,Lj) ) / min(|Li|, |Lj|))where|Li| and |Lj| are the lengths of

Levenshtein distance

2009-08-26T10:03:00.000-07:00

Levenshtein distance, also known as edit distance, is a metric that measures the amount of differences between two given sequences. Wikipedia says the Levenshtein distance between two strings is given by the minimum number of operations needed to transform one string into the other, where an operation is an insertion, deletion, or substitution of a single character.Usage: It is often used in

Ontology Search Engines

2009-08-26T07:36:00.000-07:00

I was looking for an ontology. I found that there exist many ontology search engines. Beauty of these search engines is that they only search ontologies unlike Google, and Yahoo which are general web search engines. Why do we need ontology search engines?They help to find the suitable ontologies for given user requirements so that reuse of knowledge bases can be made.ExamplesSWOOGLE: An ontology

Bloggers are the sensors

2009-08-25T15:34:00.000-07:00

I prefer to say: "BLOGGERS ARE THE SENSORS". Sensors are triggered as soon as they sense the changes in the environment; bloggers are triggered as soon as they sense popular news or stories in the society. Similarly, sensors help humankind by providing their services. A number of BLOGGERS can easily direct the society by providing their views. Think from another angle, what if sensors of a

How is blogosphere growing ?

2009-08-25T06:28:00.000-07:00

According to some estimates, “the size of the Blogosphere continues to double every six months” and there are over seventy million blogs (with many that are actively posting). However, some studies indicate that of all these blogs and feeds, the ones that really matter are relatively few.

A nice saying of Mahatma Gandhi

2009-08-13T17:20:00.000-07:00

Last week I read an article which had quoted a saying of Mahatma Gandhi, a famous Indian politician. The apothegm was: "You may never know what results come of your action, but if you do nothing, there will be no result".The adage is so simple but carries much meaning. It is true that we may or may not know the outcomes of our actions. As an example, we won't know what benefits we get if we

Retrospect: Flash back to 11 August, 2006

2009-08-13T02:11:00.000-07:00

I’m not going to talk about 9/11 because it was not 9/11. Rather it was 8/11 i.e. August 11, 2006. May be you guys have forgotten this date. If so, let us retrospect to the date. Now you already loaded the date in your memory, didn’t you? You are right - it was the day when we’d taken a flight to Thailand in order to join our master’s program at AIT. I can guess the flight was the first

Nothing we know is truly independent of context

2009-07-26T03:13:00.000-07:00

Recently, I read a sentance written by Laren, Ellen J. Langer, psychology professor at Harvard University in an article available at [1]. The sentence is: "Nothing we know is truly independent of context". The more I went through it, the more interesting it became. As a result, I decided to share it through my blog. I hope you will enjoy reading this blog post.What we learned in our school

As it was my last day in Berlin (June 26, 2009), the capital of modern Germany, and many places were still remained to discover, I'd decided to wake up early in the morning. Accordingly, I woke up at 6:45 am and when it was around 7:35 am I went to ground floor for my breakfast. The place was at a hostel named St. Christhopher's Inns, ROSA - LUXEMBERG PLAZA, BERLIN which is at the heart of the

When will this recession ends?

2009-05-02T05:21:00.000-07:00

Everybody in the world is affected by recession. All of them are eagerly waiting for its end date. Although it is hard to say when it is going to be end, history can assist to think about it. In this article, I will paraphrase the major recessions and their life period.According to the Bishambher Pyakurel, there are many recessions since last 70 years [1]. The major recessions and corresponding

OPINION: "Life is a computer Program"

2009-03-21T02:22:00.000-07:00

Despite some differences, a Life and a Computer Program have many similarities. In this article, I will analyze the similarities between them. First I define some of the terms as:Computer Program: "A computer program is a collection of instructions"Life :"A human life is a collection of instructions"Programmer: One who writes programsEnvironment: The way a program is written .

Can problems be solved by laws and legal systems ?

2009-02-01T06:54:00.000-08:00

Many people think that laws and legal systems are the only thing that a nation should have in order to keep things in control. In South Asia, we frequently talk about laws. For example, we talk about the laws for women empowerment, child labor, terrorism, dowry etc. However, I personally don't believe only on the legal systems. What I think is that the laws and orders make sense when it applies

Definitions of few words in linguistics

2009-01-03T15:25:00.000-08:00

Today I am presenting the definitions for few words which are commonly used in linguistic. They are Synonymy, Antonymy, Hypernymy, Hyponymy & Meronymy, and Corpus. Note that I have used Wikipedia for the definitions.Synonymy: Synonyms are the different words but refers to the same or similar meaning. State of being synonyms is called Synonymy and words which are synonyms are called synonymous.

JXTA

2008-12-20T02:05:00.001-08:00

I have been knowing JXTA since 2 years ago while I was studying P2P networks at AIT. At that time, I couldn't allocate my time to go through it. At present I need to work on it and, therefore, I spent my whole week on JXTA and played with the sample applications which use JXTA. Just few minutes ago, I took a quiz from Sun Microsystem's website. My score was more than 80 %. This indicates that my
