Real-time data collection in Linux: Multiuser UNIX-like operating systems such as Linux are often considered unsuitable for real-time data collection because of the potential for indeterminate timing latencies resulting from preemptive scheduling. In this paper, Linux is shown to be fully adequate for precisely controlled programming with millisecond resolution or better. The Linux system calls that subserve such timing control are described and tested and then utilized in a MIDI-based program for tapping and music performance experiments.

The timing of this program, including data input and output, is shown to be accurate at the millisecond level. This demonstrates that Linux , with proper programming, is suitable for real-time experiment software. In addition, the detailed description and test of both the operating system facilities and the application program itself may serve as a model for publicly documenting programming methods and software performance on other operating systems.

Tuning Linux to meet real time requirements. There is a desire to use Linux in military systems. Customers are requesting contractors to use open source to the maximal possible extent in contracts. Linux is probably the best operating system of choice to meet this need. It is widely used. It is free. It is royalty free, and, best of all, it is completely open source. However, there is a problem. Linux was not originally built to be a real time operating system.

There are many places where interrupts can and will be blocked for an indeterminate amount of time. There have been several attempts to bridge this gap. One of them is from RTLinux, which attempts to build a microkernel underneath Linux. The microkernel will handle all interrupts and then pass it up to the Linux operating system. This does insure good interrupt latency; however, it is not free [1].

Another is RTAI, which provides a similar typed interface; however, the PowerPC platform, which is used widely in real time embedded community, was stated as "recovering" [2]. Thus this is not suited for military usage. This paper provides a method for tuning a standard Linux kernel so it can meet the real time requirement of an embedded system.

You'll gain the insight of examples drawn from real-world scenarios, with detailed guidance and authoritative coverage of key topics, including GNU and Unix commands, system operation, system administration, system services, secu. Recent advances in high-throughput technologies dramatically increase biological data generation. However, many research groups lack computing facilities and specialists. This is an obstacle that remains to be addressed. Here, we present a Linux distribution, LXtoo, to provide a flexible computing platform for bioinformatics analysis.

Unlike most of the existing live Linux distributions for bioinformatics limiting their usage to sequence analysis and protein structure prediction, LXtoo incorporates a comprehensive collection of bioinformatics software, including data mining tools for microarray and proteomics, protein-protein interaction analysis, and computationally complex tasks like molecular dynamics. Moreover, most of the programs have been configured and optimized for high performance computing. LXtoo aims to provide well-supported computing environment tailored for bioinformatics research, reducing duplication of efforts in building computing infrastructure.

Therefore a real-time operating system is not essential for device control. This article focuses on the experience of creating a customized Linux distribution for front-end IOC deployment. Rationale, a road-map of the process, and efficiency advantages in personnel training and system management realized by using a single OS will be discussed. Windows and doors.

Linux operating system LOS is a sophisticated man-made system and one of the most ubiquitous operating systems. However, there is little research on the structure and functionality evolution of LOS from the prospective of networks. In this paper, we investigate the evolution of the LOS network. It is found that the size of the LOS network grows almost linearly, while clustering coefficient monotonically decays. The degree distributions are almost the same: We further explore the functionality evolution of the LOS network.

It is observed that the evolution of functional modules is shown as a sequence of seven events changes succeeding each other, including continuing, growth, contraction, birth, splitting, death and merging events. By means of a statistical analysis of these events in the top 4 largest components i. Our work exemplifies a better understanding and describing of the dynamics of LOS evolution. For many years OSE has been a common used operating system, with real time extensions enhancements, in embed-ded systems.

Using the Internet in security-critical areas requires cryptographic protection, for which IP Security IPsec defines suitable protocols. This paper gives an overview of IP Window Stories. This research project has investigated 17 households in Germany cities and rural areas. The main aim was to learn about the significance of the window to these people: What they think of their windows , how, when and why they use them in their everyday life, if they have a favorite window and wh Application-level solutions, including both checkpointing and fault-tolerant algorithms, are recognized as more time and space efficient than system-level checkpoints, which cannot make use of any application-specific knowledge.

However, system-level checkpointing allows for preemption, making it suitable for responding to ''fault precursors'' for instance, elevated error rates from ECC memory or network CRCs, or elevated temperature from sensors. Preemption can also increase the efficiency of batch scheduling; for instance reducing idle cycles by allowing for shutdown without any queue draining period or reallocation of resources to eliminate idle nodes when better fitting jobs are queued , and reducing the average queued time by limiting large jobs to running during off-peak hours, without the need to limit the length of such jobs.

Each of these potential uses makes BLCR a valuable tool for efficient resource management in Linux clusters. A method for energy window optimization for quantitative tasks that includes the effects of model-mismatch on bias: Quantitative Yttrium 90 Y bremsstrahlung single photon emission computed tomography SPECT imaging has shown great potential to provide reliable estimates of 90 Y activity distribution for targeted radionuclide therapy dosimetry applications.

One factor that potentially affects the reliability of the activity estimates is the choice of the acquisition energy window. In contrast to imaging conventional gamma photon emitters where the acquisition energy windows are usually placed around photopeaks, there has been great variation in the choice of the acquisition energy window for 90 Y imaging due to the continuous and broad energy distribution of the bremsstrahlung photons. In quantitative imaging of conventional gamma photon emitters, previous methods for optimizing the acquisition energy window assumed unbiased estimators and used the variance in the estimates as a figure of merit FOM.

However, for situations, such as 90 Y imaging, where there are errors in the modeling of the image formation process used in the reconstruction there will be bias in the activity estimates. In 90 Y bremsstrahlung imaging this will be especially important due to the high levels of scatter, multiple scatter, and collimator septal penetration and scatter.

Thus variance will not be a complete measure of reliability of the estimates and thus is not a complete FOM. To address this, we first aimed to develop a new method to optimize the energy window that accounts for both the bias due to model-mismatch and the variance of the activity estimates. We applied this method to optimize the acquisition energy window for quantitative 90 Y bremsstrahlung SPECT imaging in microsphere brachytherapy. Since absorbed dose is defined as the absorbed energy from the radiation per unit mass of tissues in this new method we proposed a mass-weighted root mean squared error of the volume of interest VOI activity estimates as the FOM.

To calculate this FOM, two analytical expressions were derived for. To calculate this FOM, two analytical expressions were. Windows 8 secrets.
