Abstract C language programming is more and more favoured by the majority of technical personnel in embedded systems. The application of C language technology in computer software programming can effectively avoid unnecessary language logic problems, ensure the smooth progress of programming work and effectively improve the quality and efficiency of programming. For the development of C language embedded system, the programming ideas of system software are explained, the functional module division based on hierarchical design is given, and the realization methods of project organization, program framework design, module reuse design, etc. in the software development process are clarified. To solve the contradiction between C language flexibility and application development engineering. Although it is introduced for the ARM platform, the basic experience and algorithms are also suitable for software design on other embedded platforms.

The Impact

Noncontacting mechanical seals with various kinds of face surface modifications have established their position in the sealing technique. Over the last few years, a lot of works dedicated to the impact of various surface modifications on the dynamics of working rings have been created. This paper presents model studies regarding relatively unknown noncontacting impulse gas face seals. Here, a mathematical model of impulse gas face seals is developed including the nonlinear Reynolds equation and stator dynamics equations, which were solved simultaneously using numerical methods. An original computer software written in C + + language was developed. A number of numerical tests were conducted and the phenomena occurring in the radial gap during seal operation were analyzed. Final conclusions were drawn and several features were indicated characterizing impulse face seals. It should be emphasized that numerical research on this type of seals has not been published yet. The literature usually presents simplified models for the noncompressible medium, which can be solved with the use of analytical methods.

This paper describes the design and implementation of a mini multi-process micro-kernel embedded Unix-like operating system on ARM platform in technical details, including MMU and memory space mapping, init process, inter-process communication, process management, TTY and tiny shell, multi-level priority-queue schedule, and signaling. The mini OS is developed on Linux platform with GNU tool chain by the author of this paper. The architecture of the mini OS is analogous to that of Minix. Based on it, other operating system components such as file system, network management, and copy-on-write can be appended to form a full-featured embedded operating system. The mini OS can be used for both embedded system application development and related curriculum teaching.

Research On Application

While previous research on application adoption has partly advanced our understanding of factors affecting the adoption of mobile applications, less attention has been given to the whole process of application development, from idea characteristics to the supportive activities after launch. In particular, less is known about these factors in the context of developing countries, where mobile applications are gaining increasing popularity. In this vein, this paper, adopting a grounded theory approach, aims to identify factors influencing the adoption of entertainment mobile application from the developer's points of view focusing on different phases of application development in the novel context of Iran. The authors' in-depth semi-structured interviews with experts in mobile application development firms indicate 15 factors classified within four categories based on the application development process, entailing idea characteristics, design, marketing communications and supportive activities. The implications of these findings provides valuable insight into why some mobile applications are more successful than others.

Some restaurants are to develop the concept by placing the gazebo-gazebo that were located far apart. With a large area and a place to eat with the amount that more and more the restaurant must provide the waitresses in considerable amounts. Often when the waiter is still busy serving the other guests, then there will be visitors restaurants that can not be served well. In addition, the number of waiters that too many would economically burden the employers because it would result in expenditure will be even greater. Then it can be developed an information system involving hardware and software to apply the reservation system that can be done from the tables or places to eat at a restaurant. Systems built using hardware and software. The hardware is built by using the AVR microcontroller device comprising an IC (Integrated Circuit) which is supported by the power supply, as well as some passive and active components. Software on a microcontroller using C language development tool using CodeVision of AVR. While the computer software using Visual Basic 6.0 programming language. Food ordering system that created it can improve services for consumers in terms of booking. Buyers can make a reservation at the dinner table without going through the waitress who had approached the table and write whatever menu you want to order. Additional bookings can also be done through the table without leaving the place or the waiter.
