This will be Lesson-05 (Part 5.3) in MS PROJECT 2010 Course and we will learn about:

Assigning Material Resources to Tasks. This includes:

1-Entering Resources on Task Information Tab

2-Entering Resources in Detail View

3-Adding Assignment Units

 

Material resources can also be assigned to tasks the same way as Work Resources -- through Task Information Tab, Detail View, etc. When Material resources are assigned to a particular task, there is no effect on the task duration, because material has no work related component. Material Resources add up to the task cost based on the number of units of the material being used.

 

How Air Conditioning (AC) Works

Many residences in warm climates get air conditioning. For a few, air conditioning could be a luxury, except for many, this is a must. Offered the expenses from the tools and the power to manage that, These kinds of 10 factors should complete a purchaser more conscious of the environment conditioning method and better competent to maintain that and work with it nicely. Really should that become required to replace of which method, search for an experienced HEATING AND COOLING professional.

What exactly is Air conditioning?
The first practical classification connected with air-conditioning is made throughout 1908 which is added in order to Gary. B. Wilson. It is the classification which Willis Carrier, the actual “father connected with atmosphere conditioning” activated in order to:

• Retain appropriate humidity to all regions of a building
• Free mid-air coming from excessive humidity while in selected conditions
• Provide a consistent and adequate availability of fresh air
• Effectively take away from your atmosphere micro-organisms, particles, soot, and also other unusual physiques
• Effectively cool room atmosphere while in selected conditions
• High temperature or maybe aid heat the actual suites throughout winter season
• A great device that's not cost-prohibitive throughout obtain or maybe preservation.

 

How Air Condition works ?

The job of your house air conditioning unit is transfer warmth via in the home towards the exterior, therefore cooling down you plus your residence. Air conditioning hit trendy air straight into your home through tugging the warmth away from in which air. The oxygen is chilled through coming it in excess of a couple of frosty plumbing called the evaporator coils. This kind of is effective similar to the cooling down that takes place as soon as h2o evaporates out of your skin tone. Your evaporator coils is filled with a unique water called a new refrigerant, which alterations from a water into a gasoline mainly because it absorbs warmth through the air. Your refrigerant is pumped away from the property to a different coils where it offers up their warmth in addition to alterations into a new water. This kind of exterior coils is named the particular condenser for the reason that refrigerant is condensing from a gasoline here we are at a new liquid much like moisture over a frosty windows. A send, called a new compressor, is needed to maneuver the particular refrigerant involving the a couple coils and to transform the particular demand from the refrigerant in order that all of the refrigerant evaporates or even condenses from the correct coils.

The energy to accomplish involves is needed from the generator in which runs the particular compressor. The complete method can typically provide three periods the particular cooling down strength that this compressor employs. This kind of strange truth is really because the particular modifying of refrigerant from a water into a gasoline in addition to returning why don't we the device transfer considerably more strength versus compressor employs.

How to make a radar/sonar using arduino UNO and processing

Radar system uses radio waves to detects objects and determines distance, altitude, speed and direction of that object. In our project, we are using Arduino UNO to control the system, UltraSonic sensor (HC-SR04) to send and receive signal and servo to keep rotating the sensor by 90 degrees.

 

List of parts used in this project:

1- Arduino UNO 
first and the most important component is the micro controller. In this project, we have used Arduino UNO. for more information, please visit arduino.cc

 

2- Ultrasonic sensor
Ultrasonic ranging module HC-SR04 provides 2cm to 400cm non-contact
measurement function, the ranging accuracy can reach to 3mm. The module
includes control circuit, ultrasonic transmitters and receiver. 

The basic principle of work:
a- Using Input output trigger for at least 10Micro seconds high level signal
b- The Module automatically sends eight 40 Khz and detect whether there is a
pulse signal back.
c- If the signal back, through high level , time of high output Input output duration is
the time from sending ultrasonic to returning.

 

3- Servo
You can use any suitable servo, in this project, we have used Tower Pro micro servo 9g, it can rotates from 0 to 180. in this project, we have used from 45 to 135 degrees.

Java interview questions

As we mentioned in our previous articles, facing an interview is a stressful job. It doesn’t matter if you are experienced or not, we all feel anxious before an interview.

In today’s article we will talk about Java Interviews. Our advice is that if you are not good at programming, do not apply for such an interview.

What does Java mean?

Java is a platform independent programming language also called OOP (Object Oriented Programming). This language was discovered by James Gosling in 1991.

Java represents one of the most used programming languages in the world. Java platform is being used for making phone, tablets, and desktops applications and for more other IT devices. The request for Java workers has increased and this is an emerging market.

Enough describing Java. If you want to apply for a java interview you should already now this information.

There are java interviews for juniors and for seniors. Let’s take the junior java interviews:

Usually, junior java interviews are structured in four different parts:

• Technical part writing
• Logical test, writing
• Interview with a Human Resources delegate
• Interview with future boss

Examples of java interview questions:.

Example 1) Define the concept of polymorphism

Answer: The same name can refer to two different methods: Overloading and Overriding.

Example 2) what does encapsulation mean?

Answer: The objects classes’ characteristic to group together under the same structure the data and the methods applicable to them.  It also separates the private and public data.

Example 3) what is Java inheritance?

Answer: It’s a characteristic through which an objects class can use the properties and methods of another class and add its own functionality.

Example 4) what is an “abstract class”?

Answer: A class that is defined by using the keyword: “abstract”. It doesn’t allow objects of its prototype to be created.

Example 5) what is the difference between “set and list”?

Answer: In “set”, the elements are unique.

Example 6) how are parameters transmitted in Java?

Answer: Trough value.

Example 7) what’s the “Exception class’s superclass”?

Answer: Its superclass is Throwable which has two underclasses: Exception and Error.

Example 8) what is a “finally block”?

Answer: The code in finally block will always be executed.

Example 9) what is marker interface?

Answer: Marker interface is a design pattern; it provides a way to associate metadata with a class where language doesn’t have explicit support.

Our last java interview questions example is: “What is immutable object?”

Answer: An immutable object once created, can’t be modified.

There are hundreds of java interview questions and maybe in our future articles we will present some more.

If you don’t know how to work in java but you want to learn, we would recommend “Effective Java” by Joshua Bloch.

Hotel Management

Tourism has become one of the major industries all around the world. It is an explosively growing branch. In order to be able to cope with the new challenges and demands someone thought that it would be more than welcomed a place where those who are interested in tourism and management to be able to learn in a short time how to make people who travel a lot to fell most welcomed, to learn about hotel management. Hotels accommodate all around the world thousands of people who are away from their homes and are looking for something similar even if they are “on the road”.

Tourism became so complex and demanding that it started to cover not only hotels, motels, motels, lodges, cottages, camps, casinos, etc. But also here are included services like transport, catering, restaurants, gift shops, spa, etc. All this web of services has to be controlled and directed towards serving the clients. That’s why hotel management and even more than that have to be taught and learnt. 

For some passionate people regarding hotel administration managing a hotel or a chain of hotels became an art, a lifestyle, an obsession. Managing a hotel is no walk in a park at all. 

Accommodation includes services like:

• Front office – the place where is made: 
  • $ - the booking
  • $ - advertisement 
  • $ - keys management
  • $ - cashing the bills
  • $ - collaborating with other compartments
• Housekeeping – implies cleaning, sanitizing the rooms, etc.
• Technical sector – keeps everything running (furniture, plumbing, heating, 
• Security – very important to make the customers feel secure and safe. Security personnel are crucial in a hotel. 
• Marketing implies:
• Market prospecting 
• Knowing the customers, their mentality, behavior.
• Elaborating a managerial plan 
• Organizing promotional activities, discounts.
• Negotiating and closing deals.
• The accounting sector.

Hotel management also implies being hospitable, offering good and healthy food presented in a desirable way which to combine a fabulous taste of the food and an eye catching view of the dish in the restaurant. One of the important parts in the overall scheme of managing a hotel is the HR i.e. human resources department. This department has a decisive contribution in offering a high quality service of the hotel to the increasingly demanding clients. That’s why having sufficient and of a good quality personnel is vital for the hotel manager.

A medium four star hotel **** includes a General Manager, an Assistant General Manager, a Director of Finances, Director of Food and Beverage, a Director of Front Office, an Executive Housekeeper, a Maître D’Hotel, an Executive Chef, a Director of Human Resources, a Director of Security, an Information Technology Manager, a Director of Events and Catering, a Director of Sales and Marketing and a good deal of dedicated men and women ready to make the stay confortable and pleasant for everyone. 

Anyone who is interested in working long shifts, starting with the General Manager, late hours, long weekends, and holidays due to 24 hours operation of a hotel are more that welcomed to join the party.

Online reputation management

Your reputation precedes you. Who doesn’t want to hear these words? We all want to be popular and to have a great reputation.

When talking about companies’ reputation, this is one of the most important aspects of a business. If a company’s reputation is bad, the sales will drop and if the management team doesn’t do something to change their reputation, bankruptcy is imminent. In the past, reputation was made through mouth-to-mouth, today, reputation is created mostly online.

We will talk about companies’ online reputation management.

The most important aspect of online reputation management is that only the first 30 results really matter. When I say 30 results I mean google searching results. When someone is searching for your company, the first 30 results are important so you need to focus on those 30 results in order to create a positive reputation.

How can you build a good online reputation?

Building a real good reputation takes a lot of time and effort. The news travels much faster online that in real life. One bad experience with your company will make a person tell seven other persons about that experience in real life, and a positive experience will make a person tell only 1 or two other person about it. Online, things are different; a bad or good experience can be shared on a blog or on a social network and thousands of people can see it.  Only one bad experience can make very much damage and could take months or even years to erase that experience.  

It is very important to offer your clients predictable and identical experience so they now what to expect and in this way they will always give you great reviews.

Searching engines

A search engine is very important in building a reputation because if your company doesn’t show up in the search results, you basically don’t exist online.  The statistics show that 49% of the customers will buy a product based on its internet reviews.

Google invented a new instrument that will help you manage the online search of your name. you can find it here: http://googlepublicpolicy.blogspot.ro/2011/06/me-myself-and-i-helping-to-manage-your.html

If you want to build good online reputation you need to initiate conversations on blogs and social media, to be involved in the lives of online communities, to launch videos and materials to promote your company. In other words, you have to be proactive.

A useful tip in building a good online reputation is this: Never argue online, you always have to be polite and solve problems wisely.

Another tip would be to check your online search results every week so if something has come up you are able react.  

Our last tip is to have official press releases as often as possible because it will increase your online rankings.

Reputation is everything for a company, so invest in it wisely, be patient and follow our steps.

3D Animation Of V8 Engine Fuel Injected

 

A V8 engine is a V engine with eight cylinders mounted on the crankcase in two banks of four cylinders, in most cases set at a right angle to each other but sometimes at a narrower angle, with all eight pistons driving a common crankshaft.

In its simplest form, it is basically two straight-4 engines sharing a common crankshaft. However, this simple configuration, with a single-plane crankshaft, has the same secondary dynamic imbalance problems as two straight-4s, resulting in vibrations in large engine displacements. As a result, since the 1920s most V8s have used the somewhat more complex crossplane crankshaft with heavy counterweights to eliminate the vibrations. This results in an engine which is smoother than a V6, while being considerably less expensive than a V12 engine. Most racing V8s continue to use the single plane crankshaft because it allows faster acceleration and more efficient exhaust system designs.

How CD ROM works (Animated video)

 

CD-ROM (Compact Disc, read-only-memory) is an adaptation of the CD that is designed to store computer data in the form of text and graphics, as well as hi-fi stereo sound. The original data format standard was defined by Philips and Sony in the 1983 Yellow Book. Other standards are used in conjunction with it to define directory and file structures, including ISO 9660, HFS (Hierarchal File System, for Macintosh computers), and Hybrid HFS-ISO. Format of the CD-ROM is the same as for audio CDs: a standard CD is 120 mm (4.75 inches) in diameter and 1.2 mm (0.05 inches) thick and is composed of a polycarbonate plastic substrate (underlayer - this is the main body of the disc), one or more thin reflective metal (usually aluminum) layers, and a lacquer coating.

The Yellow Book specifications were so general that there was some fear in the industry that multiple incompatible and proprietary formats would be created. In order to prevent such an occurrence, representatives from industry leaders met at the High Sierra Hotel in Lake Tahoe to collaborate on a common standard. Nicknamed the High Sierra Format, this version was later modified to become ISO 9660. Today, CD-ROMs are standardized and will work in any standard CD-ROM drive. CD-ROM drives can also read audio compact discs for music, although CD players cannot read CD-ROM discs.

 

How Turbocharger works

A turbocharger is (usually) a way of getting more power out of an engine without increasing the displacement of the engine. This might allow a 1.5l engine to behave more like a 2.0l engine when extra power is required. You can think of it as a sort of temporary engine enlarger.

As Clifford said, it's basically a pump that uses kinetic energy from the hot exhaust gas when the engine is working hard to increase the pressure of the air going into the engine. Because the air is above atmospheric pressure, it contains more oxygen than the same volume of air at atmospheric pressure. This means that more fuel can be mixed with the air to produce more power, and that results in even more hot exhaust gas to drive the turbine.
