At the root Xiaomi was minded company who wanted to release a smartphone with attractive performance and low cost. The initial investors for a young ambitious company made the Chinese venture capital funds. The Xiaomi it is not just a CEO of, but also the inspiration and ideologist of creating the concept of the products of this brand. By the way, the presentation of CEO Xiaomi prefers to spend in jeans, but instead wears a turtleneck shirt or shirt.
Another interesting fact. Lei Jun has an excellent operability. His usual working hours - 12 hours, 6 days a week. And that such a schedule, he encourages other top managers Xiaomi. So what is the secret of success Xiaomi?
In my opinion, not in the production of cheap smart phones. Now it is difficult to surprise anyone. Especially when it comes to many manufacturers from China. More importantly, that Xiaomi has turned clearly identify itself in the market and to find its niche. The first step to success for this manufacturer became the property of the shell for Android, which is loved by millions of users. And, Xiaomi sensitive to the problems and suggestions that arose from her audience.
In particular, when there were problems with the first batch of Xiaomi Mi-ONEthe manufacturer was able to quickly solve them by signing a contract with a large number of partners and actually organize their own service network. And, in my opinion, it is focus on the needs and desires of the user, as well as constantly developing proprietary shell and became a key to success for Xiaomi. Of course, it was not without affordable and powerful smartphones this would succeed.
But, just to release cheap and powerful smartphone is not enough, you need to be able to create a device that users will love. And Xiaomi succeeded.

They are only used for internal analysis by the website operator, e.Jul 31, 4 comments. Learn all about Entity Relationship Diagrams ERDswhat they are used for, how to understand them, how to create them, and more in this guide. They are created when a new system is being designed so that the development team can understand how to structure the database. They can also be created on an existing system to help the team understand how the system works and to find and resolve any issues.
Entity Relationship Diagrams use a specific set of symbols, such as shapes and arrows, to depict the system and database.
An entity is a thing that can have data stored about it. It can be a physical object e. They represent nouns. A strong entity has an identifier a primary key and does not depend on any other entities for it to exist. For example, a student may be a strong entity, as it can have a primary key and does not depend on any other entities for it to exist. A weak entity is one that depends on a strong entity for existence. This means it has a foreign key to another entity. For example, an enrolment of a student may be a weak entity, as an enrolment cannot exist without a student.
A relationship in an ERD defines how two entities are related to each other. They can be derived from verbs when speaking about a database or a set of entities. An attribute is a property of an entity or something that can be used to describe an entity.
They are often represented as ovals, or as entries inside an entity. Cardinality represents the number of instances of an entity that exist in a relationship between two entities.Michael Jackson - Billie Jean (Official Video)
This is often expressed as a number but could also be a symbol, depending on the style of diagram used. Common cardinality values are zero, one, or many. When we are creating an ERD we often have an idea of what we want to capture. These sentences include a few different types of words, which can be used as a starting point for an ERD.
They are represented in a few different ways:. When creating an ERD, it can be simple to create boxes and lines between them.
But, like many things in software development, there are a few different methods and standards that are available. For ERDs, there are several notation standards, which define the symbols used. An Entity Relationship Diagram can be drawn at three different levels: conceptual, logical, or physical.Despite the huge variety of possibilities in modern smartphones, they still continue to perform the function for which phones were initially created - mobile communications.Ati level scores
The functionality of this function is provided by a SIM card inserted into the special slot and even several. However, it is not uncommon for new and already used smartphones to have problems with communication - Xiaomi does not see the SIM card.
This problem has several causes, and their most accurate detection is very important in this case, since further actions depend on them. These cases are good because most often the user can independently deal with this problem without resorting to the help of specialists.
Hardware nuances arise on new devices most often this is a normal marriage and on already used perhaps the phone had time to fly somewhere or swim. Some nuances can be eliminated on their own, but more serious ones require knowledge of the case. Does the SIM itself work? Perhaps she had been lying idle for a long time, and the operator turned it off. Contact the call center to solve this problem. The sim card can be very old, the contacts are damaged or oxidized. Try to clean them with a cotton swab dipped in medical alcohol.
Also check the contacts on the smartphone itself - if necessary, perform the same operation with them, using the minimum amount of alcohol to prevent it from swirling inside. Is the card firmly in the slot? Replace the card from the operator or repair the slot by contacting a specialist.
Perhaps you have a version of the device, in which the modem does not support local mobile frequencies. This often happens when ordering a phone directly from China, which, accordingly, have a hardware configuration different from the export models.
There's nothing you can do - negotiate with the seller. Often there is a nuance on new devices - a normal marriage. Please contact the store where you bought the phone, let experts know about it if the phone, of course, under warranty. Repair will not give up, of course, but with the guarantee is free.
It is better to require a full replacement of the device - more likely that the problem will not make itself felt again. If the above tips do not help to solve the problem, then, most likely, the matter is more serious. Phone stuffing may be damaged, some sort of postings or a loop may be damaged this is usually manifested by some symptoms other than SIM card slots.
It is advisable to contact an authorized service center for people who know how to fix these phones.Xiaomi is one of the most flexible manufacturers of smartphones in terms of taking into account the wishes of customers.
Therefore, inthe market began to produce smartphones of the most accessible category. The first budget workers from Xiaomi received the MediaTek processors. This was the main difference between the Redmi lineup from Mi. At the moment, the Chinese giant has begun to work more closely with Qualcomm and some models of Redmi have been launched on the basis of Snapdragon. At the same time the cost of phones did not crawl up.
The Redmi series is designed for undemanding users. These smartphones are characterized by mediocre characteristics and are suitable for users who do not chase the top iron. Therefore, these phones are unlikely to draw the most powerful games. The Redmi series gets mid-level processors. The biggest difference between the Redmi series from Mi -smartphones is the internal stuffing.
Xiaomi uses inexpensive components, targeting a mass buyer. Redmi-series features a minimalist design. In the case of Redmi -smartphones, Xiaomi is also trying to save on design. And although this series is also manufactured with aluminum casings, but their quality is not the same level as the top models. Redmi -smartphones are aimed at buyers as much as possible. The series focuses on the latest trends, offering at the moment improved front cameras for high-quality self-photo, modules with PDAF.

Smartphones of this line are considered the most compact with screens up to 5 inches. At first, Redmi smartphones were made with polycarbonate cases, but, starting with Redmi 3the design radically changed and the phones received a metal case, as well as a fingerprint scanner.
This series also refers to the budget line, but they differ in the increased size of the screens 5. Since Redmi Note 3the line has received a premium-style, aluminum body and a fast fingerprint scanner. Prior to it, smartphones were manufactured with polycarbonate enclosures.

If you find any bugs, please report them. The Scale and Chord Tone Fretboard Printer is a free fretboard generator for any stringed instrument. I designed it for my bass students and for you to use.
This free scale and chord generator allows you to view and print out the fretboard notes or fingerboard charts to most any scale, chord, or arpeggio on any stringed instrument in any tuning.
The default tuning displays a bass fretboardbut don't be fooled. It supports all stringed instruments — like guitar, bass guitar, violin, cello, mandolin — for any number of strings in any standard tuning, dropped tuning or alternate tuning you can think of. It's a very powerful fretboard diagramming application I tried to make the scale diagrams and chord diagrams as simple and neat as possible.Half lap joint
Most musicians can't afford those color ink cartridges so all diagrams are in printer-friendly greyscale. The way the fretboard charts are displayed can be changed in a number of ways including the number of frets, starting fret, the width and height of the fretboard, etc. It is very customizable. Play around with the program; you should figure out how it works pretty easily. Good luck memorizing all of your scales, modes and chord tones!
If you have questions about using the program, help for the Scale and Chord Tone Fretboard Printer follows The fretboard printer is laid out with a piece of paper for printing at the top and a user interface at the bottom. Using the controls you can make just about any note diagram you want. On this tab you can set the number of strings and tuning note for each string for your diagram.
Many of the most popular and common tunings for popular instruments are already listed under the presets. You can also quickly create a custom instrument for any number of strings in any tuning. To select from the preset tunings, first choose an instrument. A list of preset instruments from which to choose will drop down. Click an instrument to select it. Once you've selected an instrument, if you don't want the standard tuning it loaded, click to select a new tuning.

A menu of preset tunings for that instrument will drop down.UML is a way of visualizing a software program using a collection of diagrams. The notation has evolved from the work of Grady Booch, James Rumbaugh, Ivar Jacobson, and the Rational Software Corporation to be used for object-oriented design, but it has since been extended to cover a wider variety of software engineering projects.
UML 2. The key to making a UML diagram is connecting shapes that represent an object or class with other shapes to illustrate relationships and the flow of information and data. To learn more about creating UML diagrams:. The current UML standards call for 13 different types of diagrams: class, activity, object, use case, sequence, package, state, component, communication, composite structure, interaction overview, timing, and deployment.
These diagrams are organized into two distinct groups: structural diagrams and behavioral or interaction diagrams. They describe the static structure of a system.Volume 29, issue 1 (2009)
Learn more. Watch this short video about UML Class Diagrams Package Diagram Package diagrams are a subset of class diagrams, but developers sometimes treat them as a separate technique. Package diagrams organize elements of a system into related groups to minimize dependencies between packages. Object Diagram Object diagrams describe the static structure of a system at a particular time. They can be used to test class diagrams for accuracy. Composite Structure Diagram Composite structure diagrams show the internal part of a class.
Use Case Diagram Use case diagrams model the functionality of a system using actors and use cases. Activity Diagram Activity diagrams illustrate the dynamic nature of a system by modeling the flow of control from activity to activity.
An activity represents an operation on some class in the system that results in a change in the state of the system. Typically, activity diagrams are used to model workflow or business processes and internal operation. Sequence Diagram Sequence diagrams describe interactions among classes in terms of an exchange of messages over time.
Interaction Overview Diagram Interaction overview diagrams are a combination of activity and sequence diagrams. They model a sequence of actions and let you deconstruct more complex interactions into manageable occurrences. You should use the same notation on interaction overview diagrams that you would see on an activity diagram. Timing Diagram A timing diagram is a type of behavioral or interaction UML diagram that focuses on processes that take place during a specific period of time.
They're a special instance of a sequence diagram, except time is shown to increase from left to right instead of top down. Communication Diagram Communication diagrams model the interactions between objects in sequence.
They describe both the static structure and the dynamic behavior of a system.How to report confidence intervals apa
In many ways, a communication diagram is a simplified version of a collaboration diagram introduced in UML 2. State Diagram Statechart diagramsnow known as state machine diagrams and state diagrams describe the dynamic behavior of a system in response to external stimuli.
State diagrams are especially useful in modeling reactive objects whose states are triggered by specific events. Component Diagram Component diagrams describe the organization of physical software components, including source code, run-time binary code, and executables. Deployment Diagram Deployment diagrams depict the physical resources in a system, including nodes, components, and connections.
Class diagrams are perhaps one of the most common UML diagrams used and class diagram symbols center around defining attributes of a class. For example, there are symbols for active classes and interfaces. A class symbol can also be divided to show a class's operations, attributes, and responsibilities. Lines are also important symbols to denote relationships between components.A UML diagram is a partial graphical representation view of a model of a system under design, implementation, or already in existence.
UML diagram contains graphical elements symbols - UML nodes connected with edges also known as paths or flows - that represent elements in the UML model of the designed system. The UML model of the system might also contain other documentation such as use cases written as templated texts.
The kind of the diagram is defined by the primary graphical symbols shown on the diagram. For example, a diagram where the primary symbols in the contents area are classes is class diagram. A diagram which shows use cases and actors is use case diagram.
A sequence diagram shows sequence of message exchanges between lifelines. UML specification does not preclude mixing of different kinds of diagrams, e. Consequently, the boundaries between the various kinds of diagrams are not strictly enforced. At the same time, some UML Tools do restrict set of available graphical elements which could be used when working on specific type of diagram. Structure diagrams show the static structure of the system and its parts on different abstraction and implementation levels and how they are related to each other.
The elements in a structure diagram represent the meaningful concepts of a system, and may include abstract, real world and implementation concepts. Behavior diagrams show the dynamic behavior of the objects in a system, which can be described as a series of changes to the system over time. UML 2. Note, items shown in blue are not part of official UML 2.
Note, items in blue are not part of official taxonomy of UML 2. Structure diagrams show static structure of the system and its parts on different abstraction and implementation levels and how those parts are related to each other. Structure diagrams are not utilizing time related concepts, do not show the details of dynamic behavior.
However, they may show relationships to the behaviors of the classifiers exhibited in the structure diagrams. Object diagram was defined in now obsolete UML 1. A static object diagram is an instance of a class diagram; it shows a snapshot of the detailed state of a system at a point in time. Because manifestation diagrams are not defined by UML 2.
