The wearable technology is carefully expected as a next generation business platform which can lead to changes from the smartphone-based hardware and software market. In this paper, we consider whether wearable computing environment with unlimited potential would require an operating system or not by comparing with other computing environment such as a general-purpose computer. In addition, a brief history of wearable technology and the necessity of studying about operating systems for highly merged wearable devices with software systems will be discussed. We also review the features of existing operating systems in different computing environments and discuss the elements that a wearable operating system should have.

The present work is devoted to the description of the evolution of antimonopoly cases brought against Microsoft by the American, European and Russian antimonopoly authorities. The focus of this work is on assessing the ability of Microsoft as a manufacturer of an operating system that occupies a dominant position that can influence competition in the application software market, including the browser market, antivirus protection and media players. The position in the market of operating systems is closely related to the presence of direct and indirect network effects. It was found that in most cases Microsoft was accused of obtaining vertical restrictions and related sales in order to restrict competition. In addition, in later antitrust cases against Microsoft, there has been an increasing focus on behavioral aspects.

Performance Comparisons

General-purpose computers are increasingly being used for serious control applications, due to their prevalence, low cost and high performance. Real-time operating systems are available for PCs that overcome the nondeterminism inherent in desktop operating systems. Depending on the timing requirements, however, many users can get by with a non-real-time operating system. This paper discusses timing techniques applicable to non-real-time operating systems, using Linux as an example, and compares them with the performance that can be obtained with true real-time OSes.

Abstract The predictable CPU architectures that run hard real-time tasks must be executed with isolation in order to provide a timing-analyzable execution for real-time systems. The major problems for real-time operating systems are determined by an excessive jitter, introduced mainly through task switching. This can alter deadline requirements, and, consequently, the predictability of hard real-time tasks. New requirements also arise for a real-time operating system used in mixed-criticality systems, when the executions of hard real-time applications require timing predictability. The present article discusses several solutions to improve the performance of CPU architectures and eventually overcome the Operating Systems overhead inconveniences. This paper focuses on the innovative CPU implementation named nMPRA-MT, designed for small real-time applications. This implementation uses the replication and remapping techniques for the program counter, general purpose registers and pipeline registers, enabling multiple threads to share a single pipeline assembly line. In order to increase predictability, the proposed architecture partially removes the hazard situation at the expense of larger execution latency per one instruction.

Tasks Scheduling

Wireless Sensor Networks (WSNs) are a growing research area as a large of number portable devices are being developed. This fact makes operating systems (OS) useful to homogenize the development of these devices, to reduce design times, and to provide tools for developing complex applications. This work presents an operating system scheduler for resource-constraint wireless devices, which adapts the tasks scheduling in changing environments. The proposed adaptive scheduler allows dynamically delaying the execution of low priority tasks while maintaining real-time capabilities on high priority ones. Therefore, the scheduler is useful in nodes with rechargeable batteries, as it reduces its energy consumption when battery level is low, by delaying the least critical tasks. The adaptive scheduler has been implemented and tested in real nodes, and the results show that the nodes lifetime could be increased up to 70% in some scenarios at the expense of increasing latency of low priority tasks.

A computerized infrared interpreter has been developed on an IBM personal computer (PC) running under the Microsoft disk operating system (DOS). Based on the original Merck Sharp & Dhome Research Laboratory Program for the Analysis of InfRared Spectra (PAIRS), this infrared interpreter, PC PAIRS+, is capable of analyzing infrared spectra measured from a wide variety of spectrophotometers. Modifications to PAIRS now allow the application of both artificial intelligence and library searching techniques in the program. A new algorithm has been devised to combine the results from the library searching and the PAIRS program to enhance the dependability of interpretational data. The increased capability of this infrared interpreter along with its applicability on a personal computer results in a powerful, general-purpose, and easy-to-use infrared interpretation system. Applications of PC PAIRS+ on petrochemical samples are described.

Abstract: Community service activities entitled "Installation of Operating Systems Based on Windows 10" aims to provide information to students from MAN Asahan about Installing Windows Operating Systems. The method used in this activity is a direct observation of the MAN Asahan school by watching and analyzing the problems or troubleshooting that occurs at the Computer Lab at MAN Asahan. In addition, information on problems in the computer Labs of the school was also carried out by a team of lecturers as the perpetrators of this community service by way of direct interviews with the Teachers and employees who served in the Computer Lab of the MAN Asahan school. The end result of this dedication is how students can repair computers, as well as troubleshooting that occurs on school computers and computers at home, can be overcome alone without having to use computer repair services.Keywords: installation; operating system; Windows 10 Abstrak: Kegiatan pengabdian kepada masyarakat yang diberi judul “Instalasi Sistem Operasi Berbasis Windows 10” bertujuan untuk memberikan informasi kepada siswa dan siswi MAN Asahan tentang Instalasi Sistem Operasi Windows.

The use of traditional approaches to teach Operating Systems usually lacks the visual aspect. The following research investigates the novel use of DEVS (Discrete Even Visualization and Simulation) in simulating the operation of an operating system. Cd boost++ was the framework of choice for this project. The simulation successfully mimicked the work of an operating system by simulating multiple cycles of program requests. This simulation is capable of further enhance the explanation of how an operating system works. The cases studied in this work include: 1- two processes running concurrently doing multiple IO’s, 2-four processes running concurrently based on a first come first serve scheduling algorithm, and 3- 20 processes running concurrently using highest priority scheduling algorithm. Output observation of the last case show promising results of successful use of DEVS and cd boost++ as a framework to build an operating system.
