All About Electric Car and Hybrid Car

Posted on by Rubayat M.
Tesla

I am planing to buy a new car. So I have been doing my research on different cars and technologies.Based on my research findings – I found that there are mainly four different types of technology. They are electric, hybrid , hydrogen cell and conventional. Conventional cars are the one that we know as the regular cars that we use present days. Here is what I have found.

Electric

Electric cars also known as Battery electric vehicles or BEV. These car has electric motor and rechargeable batteries. Electric motor get the power from the batteries to move. Batteries also supply power to the rest of the system. Like headlight, wiper etc. Once the battery charge is depleted, they can be recharged from a electrical outlet. Most of them do not have any conventional transmission – as it is not required.

Tesla is a good example of electric car.

How Tesla Works

Tesla cars are full electric. Tesla cars have batteries. And just like a cell phone, drivers need to recharge it. They can use a standard electrical outlet to recharge their car. Once the batteries have enough juice, the car can be driven and when the batteries are depleted, drivers need to recharge it again.

 

Hybrid

Hybrids care are between conventional car and electric car. Hybrid cars has battery, electric motor and gasoline engine. The best thing about the hybrid is that gasoline engine doesn’t have to work as hard and thus uses less fuel. Hybrids also get better mileage.

There are 2 main types of hybrid

Conventional Hybrids

During startup, the car use juice from battery to run the electric motor. When the battery charge is depleted, the gasoline engine kicks in and start powering the electric motor and also recharge the battery.When maximum acceleration is needed, both can work together.

Toyota Prius is the best example of hybrid car

How does Toyota Prius work?

During start-up and low speeds, the Prius is powered only by the electric motor, which is fed by the battery. As the battery charge is depleted, the gasoline engine responds by powering the electric generator, which recharges the battery.

 

Plug-in Hybrids

Plug-in hybrids has the same functionality like a Conventional hybrids. Major difference is –

  • These car can be plugged in to an electric outlet to recharge their batteries.
  • At the same time batteries can also be recharged when the car is on move. (like a conventional hybrid )
  • Their batteries are larger then the Conventional hybrid’s batteries. Plug-in hybrids cars can go longer distances on electric power. And just like Conventional hybrids, when maximum acceleration is needed, both can work together.

Mitsubishi’s Outlander PHEV is good example of Plug-in hybrids.

 

Hydrogen Fuel Cell

Fuel cell is a device that convert chemical energy to electricity. Fuel cells are different then battery. Battery holds electric charge and gets depleted when use. But fuel cells can continuously create electricity as long as there is a continues supply of source chemical.Fuel cell use hydrogen gas as source chemical and then it mix oxygen with it.

Benefits of Fuel Cell

  • By products are heat and water.Which is environment friendly.
  • Two to threes times more efficient than traditional combustion engines.

 

So what is the best option ?

This is hard to answer. It depends on personal preference and financial situation.

Electric Car

Good : if you live in big city. Big cities has more more people and base of that more charging stations. So in the middle of your daily commute, if your electric car lost it’s charge, you can call a tow truck and while you are wating, you are not in danger. Beside they are environment friendly.

Bad : If you live in a rural area. Less population means less charging station. Yes you can always charge your car at your home, but what if your car’s charge depleted, in the middle of nowhere ? You are stranded in the middle of no where. Besides electric cars are still very expensive. Close to $100,000 UD dollar.

Conventional Car

There is nothing much to choose – you know your budget and what you are looking for. You can a good deal from any car dealer.

Hydrogen Fuel Cell

This is another environment friendly car.

Hybrid Car

This is the best options. They are environment friendly and good on gas.

How Expensive is Formula 1

Posted on by Rubayat M.
formula-1-car

The Formula One came from the European Grand Prix Motor Racing. Grand Prix motor started in France around 1890. After the second world war, Grand Prix racing teams agreed upon to make some changes to the racing industry. That is when the idea of Formula 1 racing was born.

The reason it called Formula 1 or F1 because unlike Grand Prix Motor Racing, Formula 1 maintain some strict guideline or rules. These guideline or rules ware first imposed in 1950. Over the years many of the guidelines has been changed or updated Here are some of the guidelines or rules-

Guideline 1 : Chassis

  • An F1 car can be no more than 180 cm wide and 95 cm tall. There is no rule for maximum length.
  • The car must only have four wheels
  • Front two will be used for steering
  • Rear two will use for drive.
  • The cockpit must survive a 25 kN or 5,600 lbf) of pressure.

Guideline 2 : Engine

Engine size not not allowed to exceed 2.4L. The crankshaft must be made of steel or cast iron. As a matter of fact engine design need to follow the maximum number of guidelines.

Guideline 3 : Refueling

Every car starts with a full tank and refueling is no longer permitted during the race.

Guideline 4 : Tires

Currently there is only one official supplier – Perelli. Tires comes with five difference specification – ultra soft, super soft, soft, medium and hard. Different types of tines can only be used based on track condition. So same type of tire cannot be used in all types track.

Guideline 5 :How Winner is Decided

Winners are decided by number of points. To earn points, driver may not need to complete the race, but 90% of the racing distance must be completed during a race.

Guideline 6 : Communication between Driver and Team

  • Driver must drive the car completely unassisted.
  • Racing teams are prohibited to supply all types of track related information to the driver.
  • Driver need to win and complete the race using his driving skill and cars performance.
  • There are may other guidelines and regulation for safety and standards

 

Drivers License

Formula 1 driving license criteria list is quite long. No one can drive a Formula 1 car without a FIA Super License. To be a Formula 1 driver, one must have long driving experience.Here are few of them –

  • They must be 18 years or older and meet strict performance standards.
  • Driver must an experienced race driver and only one way to do that is to be in the racing industry for long time,
  • Driver must have different type of speed racing experience and must win numerous race. Because this is how they will collect points. Once a driver accumulated certain point they can apply for a formula 1 drivers license.
  • Licenses fess (include all regulatory fees) can go more then US $250000 dollars a year.

Speed Record

Gilles-Villeneuve (Canada) 325 km/h (203 mph),
Indianapolis (USA) 335 km/h (210 mph),
Maxium Monza (Italy) 360 km/h (225 mph).

 

Cost of the Car

Cost of the car depends on the team. Teams like Mclaren and Ferrari can spend up-to $500 million in a session. The car itself has many parts and each has it’s individual price. But the engine is the most expensive section. 2011 Mercedes spent $178.6 million on its F1 engine division.

So it all cost of the car depends how much each team is spending on different parts. On an average each formula 1 car can cost more then five million.

Driver’s Salary

Formula 1 is the ultimate goal for a speed car racer and only few can make it. It is the most expensive sporting event. Depends on the racing team, a driver can easily make millions in a years. Here are some of the driver who made big in 2016

  • Sebastian Vettel (Ferrari) – $50 million (£33.4m)
  • Fernando Alonso (McLaren) – $40 million
  • Lewis Hamilton (Mercedez) – $31 million
  • Daniel Ricciardo (Red Bull) $5.5 million
  • Pastor Maldonado (Renault) $3.2 million
  • Felipe Nasr (Sauber) $185k

The last man to walk on the moon has died

Posted on by Rubayat M.

Astronaut Eugene Cernan, commander of Apollo 17 and the last man to walk on the moon, died Jan. 16, 2017. Eugene was a member of a very prestigious club. A club that has only 12 members and they all walked in the moon.

NASA Administrator Charles Bolden released a heartfelt message after Eugene’s death.

“Gene’s footprints remain on the moon, and his achievements are imprinted in our hearts and memories. His drive to explore and do great things for his country is summed up in his own words:

‘We truly are in an age of challenge. With that challenge comes opportunity. The sky is no longer the limit. The word impossible no longer belongs in our vocabulary. We have proved that we can do whatever we have the resolve to do. The limit to our reach is our own complacency.’

“In my last conversation with him, he spoke of his lingering desire to inspire the youth of our nation to undertake the STEM (science, technology, engineering and mathematics) studies, and to dare to dream and explore. He was one of a kind and all of us in the NASA Family will miss him greatly.”

Problems with Driver-less Car

Posted on by Rubayat M.
Driver-less-Car

In last few years we have notice significant improvement in autonomous car or driver-less car or self-driving car technology. Let me explain what is an autonomous car – “autonomous car/driver-less car/self-driving car is a vehicle that is capable of navigating without human input.”

How it works

Autonomous car is actually a combination of software and hardware. If you compare us, the humans with an autonomous car, then software works as the brain of the body. There are three major parts.

Part 1 – Sensors

These vehicles have multiple sensors. These sensors collect data. These sensors are designed to detect pedestrians, cyclists, vehicles, road work and other movement from a distance in all directions. Collected data then send to the data processing software.

Part 2 – Software

Cars have specialized software that analyze the collected data and then make decision.These highly sophisticated soft-wares are able to predict the behavior of not only the cyclist or other vehicles, but of all the pedestrians in it path and around .

Part 3 – Mechanical

Rest of the body is a typical car. Except with few enhancement. Like the decision made by the analyzing software, is transferred to the car’s driving mechanism through an array of hardware.

The Problems

Driver-less cars are going to be the future. Soon it will be a house hold item. And will replace the human drivers from the public and commercial transportation system. People who work in those industry as drivers, will need to find a new career. But I am not here to talk about the future unemployment issue.
The idea of driver-less car is great but has some serious ethical and legal issue. Unless we have a clear answer of these questions, we need to think carefully about this technology.

Ethical Trust issue

Will the car ever harm or even kill the owner in order to save pedestrians ? In a serious emergency situation, who can stop the car from thinking or deciding, that saving five life (pedestrian at street) is better then saving one life (owner inside the car) ?

Car Maker Company File for Bankruptcy

To be on the road, these cars are need to be connected to various tracking system like GPS satellite, These service is provided by the car maker. Without these tracking system, the car will not be able to move. What if the car maker goes out of business completely, what will happen then ? None of the system will be available for the car to use. Scary part is no body cannot even provide any guarantee, that this will not happen.

When we have some assurance about these question, only then we can we can have full trust on driver-less car. Other wise, driver-less car will nothing but a big inconvenience to us.

2016 Year End Review of Technology, Trending, Nature, Life and Deaths

Posted on by Rubayat M.

Year 2016 was an eventful year. Citizens of this beautiful planet ware overwhelmed with crisis and calamities. Yet science and technology continued to thrive. Here are some of the notable events that happen in 2016.

Health Industry

Molecular Machine
Number for molecular components combined together forms a machine. This  movement can be manipulated through external input. Molecular machines are thousand times smaller than the width of a hair. Molecules are made up of atoms that are held together by chemical bonds and are the smallest particle in a chemical element.
Impact: This technology is still in the very early stage. But one day these machines will work inside the human body.These machines can deliver drugs within the human body directly to cancerous cells or target a specific area of tissue to medicate.Their potential is unimaginable

Three Parent Baby
Mitochondria supply energy to cell by converting food to fuel. Some people carry genetic defects in mitochondria and they can pass these on to their children. Scientist took healthy mitochondrial DNA from a donor then combined them with the DNA from the parents (DNA that contain the genetic code of the parents family).
Impact: This method can rectify the inherently transferred disease like leigh syndrome.

Information Technology Industry

Internet of Things – IoT
Every single individual device will be connected with the main network or the internet and will be able to send and receive data from other.In other word, it is more than a machine to to machine communication without human interaction. This is a cloud based system.
Impact: It’s impact is huge. One example – let say your favorite yogurt is out of stock. Your IoT equipped fridge(it comes with sensor and knows it’s inventory list) will then inform your phone(if that is what you use for order online) and your phone can place the order. Next day you received the yogurt.

Ransomware
One of the most notorious security issue of 2016. Carleton University of Canada was one the major victim of ransomware.
Read : Ransomware what it is ?

Hacking
Some high-profile hacking took place. Yahoo’s massive data breach with over a billion accounts was the biggest one.

Fake News
Fake news became the most discussed topic of 2016 during the US elections. Fake News like “Pope Francis shocks world, endorses Donald Trump for president” or “FBI agent suspected in Hillary email leaks found dead in apartment in murder-suicide” became the talk of town. Facebook, Twitter came under serious criticism after failing to stop spreading the fake news.

Automobile and Electronics Industry

Autonomous or Self Driving Car
These cars can sense its surrounding environment and can navigate from point A to B with human interaction. This technology is in the advanced stage now. More new companies joining the race. Recently Apple announce that they are also joining the club.

Samsung Galaxy Note 7
Galaxy Note 7 was prone to heating up and catching fire. Resulting in multiple injuries for consumers across the and spread panic among consumers. Some airlines also banned this phone on board. Where passengers need to switch-off their phone while on board. Samsung pulled the plug on the product and announced it was ending production.

Blackberry
Canadian technology firm BlackBerry announced it will halt in-house production of smartphones.They will focus on software, security and management. Blackberry will depend on their partners to manufacture the phones.

Aerospace Technology and NASA

Interplanetary Space Mission
After five-year journey to the solar system’s largest planet, NASA’s Juno spacecraft successfully entered Jupiter’s orbit July 4.
Read: Nasa’s Fascinating Juno Mission

Rosetta Space Probe
Rosetta was launched on 2 March 2004 and traveled 6.4 billion kilometers through the Solar System before arriving at the comet Churyumov–Gerasimenko on 6 August 2014. It successfully made the first soft landing on 12 November 2014. On 30 September 2016, the Rosetta spacecraft ended its mission by landing on the comet.

Mother Nature

Supermoon
Planet earth was blessed with the sight of three supermoon. They appear on October 16, 2016, November 14, 2016, and December 14, 2016.

Notable Deaths

Some people work tirelessly through out their entire life.The result of their efforts improve human life and lifestyle.Yet in most cases their death news never get to see the daylight. Here are some notable people in the field of science and technology who died in 2016.

  • (Medicine) Henry Heimlich (2016). Thoracic surgeon and medical researcher Henry Heimlich Invented the Heimlich maneuver.(saving choking victims via a series of abdominal thrusts)
  • (Astrophysicist) Vera Rubin(2016). Work on galaxy rotation rates. Her word confirmed the existence of dark matter.

Gooligan Malware Infected Millions of Android Devices And Google Accounts

Posted on by Rubayat M.

AndroidSecurity researcher recently discovered a new malware called Gooligan. When a user download the infected app from a third part app store, this malware get installed in the root. Then it steals the authentication tokens (some thing that your phone/device use to access google account).

Once the malware gain the access of the authentication tokens, it can then access device owner’s google account.Which include Google Play, Gmail, Google Photos, Google Docs, Google Drive etc.

 

Main Purpose Of This Malware
After install it self, Gooligan takes full control of the device and runs silently. It’s main purpose is to generate revenue. It can install apps from Google play store and then rate them. So ad companies think, an actual human is making those ratings. This means all those five stars ratings that you have seen in many apps, those may not be provided by actual human !

 

What Devices are at Risk
Android based devices are at risk. Specifically android 4 and android 5.If you use a higher version of android and If you always download from Google app store, then your devices may be in safe zone.

Check your device’s app list. If you see any one of these app, in your device, then your device may be infected. Download an antivirus app (from Google Play store of course) and remove the malware.

NewspaperAround The World

This website (www.deseat.me) will help you to delete your internet history. This site uses Googles’s OAuth protocol so they will not have to access to user’s login information. Deseat.me will run the program in user’s computer, not in their server. Once logged in it will show you a list of account that you want to delete.

Is it safe to use this service ?
You can always deactivate your online account by your self, but your previous record will still be in the online account’s server as archived files. And there may not be much you can do about it.

Rise of the Machine 1 – IBM Watson

Posted on by Rubayat M.

Recently we have noticed a significant change in artificial intelligence related technology. From house hold robots to self driven car. Any where you look around you will notice how much of this technology slowly changing our life. At the beginning of the year 2016 some of the most smartest person of our time signed a petition against the unsupervised rise of this technology.

Rise of the Machine is a series of a article that I will be writing, describing how artificial intelligence will affect our life and job sectors. This is the part 1

IBM Watson

IBM Watson

IBM Watson

Watson is a supercomputer developed by IBM. It has the ability to process natural language OR NLP and can analyze billions of information with its extremely sophisticated analytical engine. It’s users can interact with verbal communication – just like we human communicate with each other. Watson is named after IBM’s founder, Thomas J. Watson.

 

 

 

Unique Features
Watson has two unique features. These two feathers makes it so special and different then a regular computer –

  • Features 1 : Cognitive Computing.
  • Features 2 : Natural Language Processing OR NLP.

Features 1 : Cognitive Computing
Traditional computing deals with structured data. Data that is stored in the database and well defined by rules and logic. But this is not the situation any more. Today’s data are known as big data. An example of big data “Most of us have Facebook account, LinkedIn account, Instagram account ,email accounts and other social networking account. All our data are scattered all over the place. We are all interconnected to other people through these accounts made a massive data sphere. If some one try, they can find my information in this data sphere”.

Watson’s can pinpoint and analyze any specific information from this big data easily and faster then any other computer.

Features 2 : Natural Language Processing or NLP
Watson does not match text or synonyms like search engine. instead it read and interpret like a human begin. Watson uses grammar to understand the meaning of the word. So when some one verbally ask a question like this “Is black spots on the skin are symptom of skin cancer ? ”

Watson can interpret and understand this question and can answer back.

 

How Watson Think
Watson think like a human. It follows the 4 main principle steps that a human takes when it come to make decision –

  • Step 1 Observation : Like human Watson observe and collect visual data.
  • Step 2 Interpretation : Watson then verify the collected information with information that it collected in past, just like human use their memory.Based on new and existing data, Watson then try to build an hypothesis.
  • Step 3 Evaluation : This stage Watson analyze the hypothesis and try to find the best solution.
  • Step 4 Decision: Once a concrete hypothesis has been generated, Watson then execute the decision.

Of course all these steps happen extremely fast.

 

Fields That Watson is Working Now
Because of the Cognitive Computing and Natural Language Processing features Watson has become a good fit for some specific field. Fields where one require advance knowledge and training. Here are some fields that Watson is currently working and eventually will replace human work force in the future.

Healthcare
Watson is helping physicians with diagnoses. Watson helps identify potential symptoms and treatments. Additionally, Watson uses vision recognition to help doctors read scans such as X-rays and MRIs to better narrow the focus on a potential ailment. The medical field is the sector that is likely being impacted most by Watson.

Finance
Client who need financial can ask questions directly to Wason.Watson can not only answering questions, but also analyzing them as well. Watson can help give financial guidance and help manage financial risk. Just like a regular financial advisor.

Legal
Client who need legal help can ask questions to Watson, just like we ask legal question to a lawyer. Watson can analyze and answer with relevant legislation. Due to legal issue, Watson cannot work in court room as a regular lawyer at the moment. But I believe it will happen soon.

Retail
Today’s retail experiences are all about personalization. Companies are using Watons’s NLP abilities to present the most relevant product in the the most relevant time when potential clients are shopping. This help reduce the unproductive click and get the most success.

 

Watson is slowly taking over jobs sectors that require analytic ability.In near future you may find it difficult to stay employed, if currently you are working in any one of these field mention above.
