Contribution à la séparation aveugle de sources
ISBN: 9786131571329 / Francuski / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Dans cette these, nous proposons un nouvel algorithme de separation aveugle de sources, base sur l'optimisation de l'information mutuelle sous contraintes. Le probleme d'optimisation sous contraintes est resolu par passage au probleme dual. L'estimateur propose du gradient stochastique utilise l'estimation des densites par maximum de vraisemblance dans des modeles de lois exponentielles choisis par minimisation du critere AIC. Ensuite, la methode a ete generalisee a l'ensemble des divergences entre densites de probabilite. Nous avons montre que l'algorithme utilisant la divergence...

Towards an RTOS for Self-optimizing Mechatronic Systems
ISBN: 9783838126685 / Niemiecki / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The next generation of advanced mechatronic systems is expected to behave more intelligently than todays systems. They adjust their goals and behavior according to changes of the environment or system. Characteristic for these modern applications are the increasing dynamics. To handle this dynamics new approaches in the underlying system software are required. Predictability is of paramount importance for mechatronic systems. Thus, their design has to take the worst-case into account and the maximum required resources are usually allocated upfront by each process. This is safe, but usually...

Fault Tolerant Real Time Heterogeneous Distributed System
ISBN: 9783847314141 / Angielski / Miękka / 124 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Fault-tolerance becomes an important key to establish dependability in Real Time Distributed Systems (RTDS). In fault-tolerant Real Time Distributed systems, detection of fault and its recovery should be executed in timely manner so that in spite of fault occurrences the intended output of real-time computations always take place on time. Hardware and software redundancy are well-known effective methods for fault tolerance, where extra hard ware (e.g., processors, communication links) and software (e.g., tasks, messages) are added into the system to deal with faults. Performances of RTDS are...

User defined system log process
ISBN: 9783639236279 / Angielski / Miękka / 64 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Operating system observability requires communications with the system log process by the application software. IPC stands for interprocess communication, which describe the different ways of message passing between different processes that are running on some operating systems. The histories of these messages or processes are used in the software testing process. This task is done by log file analyzer. Main objective of this thesis is to propose a methodology of the system log process which is used to make the log files of the different processes running for the different software. System...

Monitoring Complex Telecom Systems
ISBN: 9783838383224 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Monitoring and debugging for a real-time system is a complicated problem due to the lack of a set of advanced tools and adequate operating system capability. Software tools can cover the wide range of the software development life cycle from the requirement analysis phase to debugging and maintenance phases. However, the tools available for development of traditional PC software are not sufficient for development of real-time systems. Real-time software tools and effective kernel support are essential to facilitate the development of real-time software as this allows developers of real-time...

The objective is to teach how to program in x86 assembly, as well as the history and basic architecture of x86 processor family. When referring to x86 we address the complete range of x86-based processors but keep in mind that x86-32 Assembly is commonly referred to as IA-32 (Intel Architecture, 32-bit) Assembly, a 32-bit extension of the original Intel x86 processor architecture. IA-32 has full backwards compatibility (16-bit). AMD64 or AMD 64-bit extension is called x86-64 and is backwards compatible with...

Real-Time Task Scheduling Modeling Using Mixed-Integer Programming
ISBN: 9783838396484 / Angielski / Miękka / 80 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Priority-driven scheduling of real-time systems has attracted considerable research in the literature. The bulk of the research focuses on attempts to explore scheduling schemes that optimize a particular parameter without meticulous considerations related to the global system's behavior. This work is concerned with the implementation of mathematical programming models developed to substantiate the effectiveness of other models.

Platform-Based Authorization Technologies
ISBN: 9783843363457 / Angielski / Miękka / 96 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Computing platforms - such as Windows operating systems - traditionally support authorization to protect accesses to well-defined persistent objects, e.g., files. Operating system authorization is usually based on the model of Discretionary Access Control (DAC) and is realized via Access Control Lists (ACLs). These mechanisms do not satisfy the needs of applications that process resources at higher levels of abstraction than the operating system. Therefore, Microsoft introduced a new authorization framework - Authorization Manager (AzMan) - which is built on the Role-Based Access Control...

Real-Time Extensions to MINIX
ISBN: 9783843391375 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Real time system applications are increasing every day. Real-time systems span from microcontrollers in automobile engines to very complex applications, such as aircraft flight control or process control in manufacturing plants. Failure in meeting the tasks deadlines can lead to catastrophic consequences. Recently, there has been an interest in techniques for developing real-time applications on general- purpose operating systems (GPOSs), like UNIX, MINIX, LINUX etc. With this in view, this work aims at adding real time extensions to the MINIX (Mini-UNIX) system. This work...

Fuzzy Uncertainty Models and Algorithms
ISBN: 9783844316476 / Angielski / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In the early phase of real-time system design only an approximate idea of the tasks and their characteristics are known. Therefore, uncertainty or impreciseness is associated with the task deadlines and processing times. It is therefore appropriate to use fuzzy numbers to model task deadlines and processing times. The book fulfills this requirement by developing several models and algorithms for fuzzy real-time scheduling using different membership function choices. It also gives task priority algorithms using a new distance measure based fuzzy criteria and considers energy efficient...

Towards Adaptive Hierarchical Scheduling
ISBN: 9783845408149 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Hierarchical scheduling provides predictable timing and temporal isolation; two properties desirable in real-time embedded systems. In hierarchically scheduled systems, subsystems should receive a sufficient amount of CPU resources in order to be able to guarantee timing constraints of its internal parts (tasks). In static systems, an exact amount of CPU resource can be allocated to a subsystem. However, in dynamic systems, where execution times of tasks vary considerably during run-time, it is desirable to give a dynamic portion of the CPU given the current load situation. In this thesis we...
