The chemicals industry (industrial chemicals, pharmaceuticals, pesticides, biocides, food and feed additives and cosmetics) is one of the largest industrial sectors in the world and one which poses many challenges for government regulators; inefficient regulation would have costly implications for the environment, human health, government budgets and the continued growth of this important global industry. Not only can different regulatory approaches and requirements in each OECD country create significant costs for the chemicals industry and for governments, they can also create barriers to trade.
If national approaches to chemical regulation are harmonised, industry is not faced with a plethora of conflicting or duplicative requirements, governments are provided with a common basis for working with each other, and non-tariff barriers to trade are reduced. The principal tools for harmonisation are a set of OECD Council Decisions which make up the OECD Mutual Acceptance of Data (MAD) system, including its OECD Guidelines for the Testing of Chemicals and OECD Principles of Good Laboratory Practice (GLP).

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

10. What is Android?
It is a open source software platform and operating system
for mobile devices
Android is a software environment built for mobile devices
It is based on the Linux kernel
Developed by Google and later Open Handset Alliance
(OHA)
Android application are built in Java language
Android has its own virtual machine called DVM(Dalvik
Virtual Machine),which is used for executing the android
application
11. Android platform is
Complete:
The android application development began with secure
operating system and robust framework for rich
application development
Open:
The platform is provided through open source licensing,
also we have access to handset features while
developing applications
Free:
Android applications are free to develop, as Andriod SDK,
ADT, etc required plugins are free
12. What is Open Handset Alliance?
Open Handset Alliance is a consortium of
47 hardware, software, and telecom companies devoted to
advancing open standards for mobile devices.
i.e. to deliver the consumer a richer, less expensive and better
mobile experience.
OHA’s aim is to Develop technologies that will significantly
lower the cost of developing and distributing mobile devices
and services.
14. Android Architecture
Before starting with Android Architecture
Why we are using Linux?
Because Linux kernel is proven core platform
It is reliable
It provides security
Hardware drivers
Process management
Memory management
Power management
15. Android Architecture
Four main Layers of Android architecture are
1. Applications
2. Application Framework
3. Libraries and Android Runtime
4. Linux Kernel
16. • Linux 2.6 Kernel
• Hardware Abstraction Layer (HAL) between
hardware and android software stack
• Provides memory management/ Process
management/ Power management
• It provides security
• Different Driver software's to manage Display,
Camera, Wi-Fi, etc…
• IPC – Inter Process Communication
17. • Android Libraries are develped in C/C++
• We cannot access these libraries directly, to access these
libraries we need application framework
Surface Manager – used for display management
Open GL/ES(Open Graphics Library/Extended system)
and SGL(Scalable Graphics Library) – used for 2D/3D
Graphics mainly for game development
Media Framework – (PacketVideo)Audio/Video codes(mp3, mpg4)
18. FreeType – Font rendering
SSL(Secured Socket Layer) – to have secure internet
connection
SQLite – Datastore i.e. Database
WebKit – Browser Engine to display webpages
libc – System C libraries
19. Core Libraries – It is written in Java language. It contains all of
the collection classes, utilities, IO.
Dalvik Virtual Machine(DVM)
• Register based Virtual Machine
• Optimized for Low memory requirements, limited
battery and limited CPU
• Designed to allow multiple VM instances to run at once
• Every program runs in its own VM instance
• Operates on DEX files
• Android byte codes are interpreted at runtime by DVM
20. • This is written in Java language and using Application
Framework we develop our Android applications.
Activity Manager – launcher, building block of
application, whatever is displayed on the screen
Window manager – It is use to create views and layouts.
Content Providers – used to share data of one application
to another. e.g. contacts, call log details
Notification manger – whenever you get emails, sms,
missed call we get notification i.e. alerts
View System – Button, textbox, checkbox, etc whatever
we see is nothing but View system
21. Resource Manager – We use View, images, audio/video
files, xml files, layout files all these additional things
we are using are handled by Resource Manger
Location Manger – It helps user to trace through
geographical location
Package Manager – It is use to retrieve the data about
installed packages on device.
Telephony manager – It is use to handle settings of
network connection and all information about
services on device.
22. • Top most layer of android architecture
• By default some applications are already available
like calculator, some browser, contacts that is
what application layer
23. Development process of an Android app
Android apps are built using Java and Android SDK
libraries
The Java code is compiled into Dalvik byte code i.e. .dex
The Dalvik Virtual Machine runs the .dex files
26. Android application Build Process
Android application are built in Java so first of all we
have Application Source Code that is our own Java
programs
If written in other language then using aidl(android
interface definition language) tools, will generate Java
interfaces
We have images, audio/video files, xml files all these
resources in our android application, which are
converted into the file called R.java
Who created this R.java then it is aapt (android asset
packing tool)
All these Java programs are given to Java compiler
Java compiler will create .class files
28. Android application Build Process
These .class files are given to dex(delvik executable tool)
tools
Some other additional class files like Google map class
files are i.e. 3rd
Party Libraries and Class Files are also
given to Dex tool
Now this Dex tool will create a single dex file.
This dex file along with the compiled resources from AAPT
and other additional resources is given to APK Builder
This APK Builder creates our android application i.e. .apk
file
