Shifts toward the connected customer, from

Exclusive to inclusive à (innovation and diversity, mass markets, social media as a redefinition of how people interact)

Vertical to horizontal

à open innovation, ecosystem business, branding (value…)

Individual to social

à most personal purchase decisions will be social decisions, lack of control over marketing communication, high impact of community generated content

As the number of eCommerce sites grows each day more and more people prefer to shop online for convenience choices and ease of price comparison online shopping experience is easier than ever before.

On the one hand The huge majority of online stores offer prices that are much lower than what you will find in a physical store. There are some good reasons for it.

Most physical stores have a restricted array of services and products. They could only carry a lot of items, and there are many policies affecting access to services and products. As an example, there may be a certain item that is only available to those versions of the business that you can get from the mall.

Shopping online enables you to find many services and products that you'll not... Continue reading "Invention by experience" »

The environment plays an important role in our lives and people wouldn't be able to live without it. However, we are polluting it every day and it needs to stop. As individuals, we can do lots of things to solve this issue, and this essay will focus on two of them - recycling and the efficient use of energy.

According to recycling, it is the easiest way to see an immediate change and everybody can do it. First, recycling bins are a great method of dividing our waste into paper, plastic, glass, etc., and they can be easily found in every city. Another idea is to reuse the things we have at home and make them new. For example, turning …. 

When it comes to the use of energy, there are many things we can do, especially at home. When we talk about... Continue reading "I choose to live" »

What is an atom?

Atoms are the basic units of matter and the defining structure of elements.

What is an electron?

A subatomic particle with a charge of negative electricity.

What is the nucleus of an atom made of?

Is made up of protons and neutrons.

What is a proton?

Elemental particle of the nucleus of the atom and that has a positive electric charge.

What is a neutron?

A subatomic particle of about the same mass as a proton but without an electric charge.

Where is the mass of an atom concentrated?

In the nucleus most of 99.9% of the mass is concentrated here.

An atom is mostly empty space?

Yes.

What is the function of neutrons?

To allow protons to be together.

What surrounds the nucleus of an atom?

The nucleus is surrounded by electron clouds that produce... Continue reading "Understanding Atoms and Quantum Mechanics: A Comprehensive Guide" »

INFORMACIÓN:

Hi Sara,

How are things? Sorry to be so slow getting back to you but... (I had to hit the books)

I was afraid to hear that... / What great news! I'm glad that...

Nudo:

In your letter you mentioned... 

Well, if I were you i would... Since...

Besides, why don't you...?

As well as that, you also wondered about...

I think you really should... Because this way...

Nudo 2:

Anyway,

I'll be delighted to pay you a visit, count me in!

Let me know when it suits you so I can plan ahead.

CONCLUSIÓ:

Well, that's all for now. I hope this was helpful. Drop me a line soon! Best wishes, Amber.

Vulnerabilities in Von Neumann Architecture

The system architect of the von Neumann is the way that it can allow direct memory access to the low level languages like C and C++.

If the program goes and tries to access the memory out of bound by allocating code injection to the system, it allows the system to access the memory out of the stack which causes buffer overflow and the attacker can access the other memory from the allocated stack. This way an attacker can get access to the system. Therefore von Neumann architecture is vulnerable to code injection, the effect of the buffer overflow.

Understanding Threats and Attacks

Threats

• It is a potential security violation that might exploit vulnerability of the system or assets.
• Threats can be accidental,

Resolution and Sensitivity

Resolution = MaxV / (2^bit - 1).

Linear Potentiometer

Total Resistance = 800 Ohms, E = 2V, L = 10 cm.

Sensitivity = V/L. Max/Min Z.

Z_out = || 80{10 - |x|}.

Z_min = 0 Ohms.

Z_max = 400 || 400 = 200 Ohms.

Unknown input impedance = voltage follower.

Gauge Factor

20mm wire strain gauge resistance = 150 Ohms. Under force tension, R changes by 5, and L changes to 0.08.

Load Cell

Load Cell Sensitivity / Minimum Value of N.

LC makes a change in V from 0 to 2V. V varies linearly.

LCS = 2V / 10N = 0.2 V/N.

Minimum Value of N = 10N / 0.1N = 100, 2⁶.

Filters

IIR Filter Identification

Unbounded, non-causal.

IIR/Unbounded. y[n-1] = 200x[n] + 300x[n-1] - 500x[n-2]. Non-causal.

Digital-to-Analog Conversion

N-bit R-2R Ladder

V = 0/6.4. n = 5.

Maximum V_out... Continue reading "Understanding Sensors, Filters, and Data Conversion" »
