  abstract = {According to the definition of a honeypot, any connection to or from this resource can
be considered as malicious and therefore as an attack. After detection, in particular, the
recognition of attackers or targeted attacks is a serious problem: Several sessions of pos-
sibly multiple attackers must be linked reliably.
For this purpose, an approach for targeted attacks is presented in this thesis which uses a
transparent proxy and a high-interaction honeypot as a foundation. These are integrated
into a complex architecture and allow an attacker to reach an isolated network segment
- the HoneyLab. Apart from the architecture active and passive measures are used to
recognize the attacker. Some of these include injection of unique credentials and URLs,
client and browser fingerprinting and a comprehensive data recording.
The main concept is to let the attacker build up a unique and compromised knowledge. If
the attacker uses this knowledge in several attacks or sessions, it will be used against him
which leads to recognition.
The implemented approach is evaluated with security professionals and random real-world
attackers. The security professionals were asked to behave as if they were participating
in a Capture the Flag (CTF) event and were reliably recognized by the approach. The
random real-world attackers could be detected but not recognized because they only used
automatic scans without any human interaction or malicious activities. Since targeted
attacks and not automatic scanners were focused, this can nevertheless be considered a
success.

culator (Material Fluss Rechner: MFR) in small warehouse systems, which

matically scanning and updating the database. It further leads to systematic
representation of data in a warehouse thereby reducing the error in various
stages of material in warehouse and eventually reducing the turnaround time.
The proposed software model and architecture guides the material on con-
veyor line to the required destination in warehouse and it updates the datalog
file cyclically. The main emphasis on developing the Material flow calcula-
tor software model is laid on the algorithm which guides the material to the
required destination as early as possible by combining the ideas from vari-
ous optimisation algorithms like Improved Djikstra’s method and Disjunctive
Branch and Bound. Furthermore a brief working algorithm model to syn-
chronise the material flow with the database is also developed. In this thesis
work we propose a routing algorithm by modelling the material flow as a job
shop problem considering all the constraints and by having makespan as an
objective function. The above proposed heuristic algorithm tends to counter
problems seen like blocking or deadlocks and schedules the flow of material
in a optimised manner on a conveyor line. In order to quantify the algorithm
the logic is written in a PLC programming language (IEC 61131-3), similar
to ANSI C language which is realised through B\&R Automation Studio soft-
ware ® and the data during material flow is recorded by a Bar code reader
which is later synchronized cyclically with the SQL server database. To val-
idate the algorithm, the proposed software model was simulated on a B\&R
PLC PC 2100, which identified MFR’s performance under various scenarios.

  abstract = {A driver-less vehicle and Vehicle-to-Anything (V2X) systems highly rely on accurate and
reliable motion information of the vehicle when it travels around the surrounding (inside
and outside) environment. As a consequence, it is essential to maintain the precise vehi-
cle’s information such as pose of the vehicle (position and direction) for its navigation.
Further, the most important dispute in autonomous application is to obtain good estima-
tion of position and orientation values for improving its performance. For accomplishing
this, the conventional localization approach seen in [1] use the measurements from Global
Navigation Satellite System (GNSS) and Inertial measurement unit (IMU).
The major drawback of that conventional approach is :
1 The errors will get accumulated over the time because of the drift present in the
IMU measurement data, and 
2 The signal from GNSS will not be fully available or not reliable i.e. sometime the
strength of the GNSS signal will be diminished in some region, for instance, in
dense urban city, inside the tunnel, etc.
Thereby, it is very difficult to get good estimation of localization information from those
sensor measurements.
In this thesis work, we propose a stereo-vision based vehicle localization method to over-
come the drawback of above mentioned traditional approach. In the proposed method,
we use visual odometry technique [2] together with IMU, GNSS, and wheel odometry for
estimating the pose of the vehicle in GPS denied environment. The measurement data
from multiple sensors are fused together using Extended Kalman Filter(EKF) approach
[3][4] to provide more accurate and reliable motion information for autonomous vehicle
navigation. The proposed method can perform with, or independently of GNSS system,
thereby it can be used as a backup to GNSS system. And also we have tested the developed algorithm on both simulated and real data.

Real-Time Synchronization on Multiprocessors through Suspension or Spinning?.

  abstract = {For many real-time applications, it is often too restrictive to assume that tasks are executed only
in a uniprocessor system and all of them are completely independent, because tasks will often
compete for shared resources. The access to the shared resource, called critical section of the task
execution, is mutually exclusive to prevent race conditions. In fact, it is not possible that two jobs
access the shared resource at the same time. As shared resources must be serially executed to
achieve mutual exclusion, the execution of critical sections inevitably causes some delay due to
priority inversion, which means, a task is prevented from executing due to another task with a
lower priority that holds a shared resource, also called pi-blocking. To avoid unnecessary blocking
of high-priority tasks due to unrelated shared resources, there exists some locking protocols. Two
well-known of these locking protocols for systems with one processor, also called uniprocessor
systems, are Priority Inheritance Protocol (PIP) [1] and the Priority Ceiling Protocol (PCP) [1].
Although the PIP could solve the problem of priority inversion, it might cause a deadlock if there
are multiple resources. Through the use of PCP proposed by Sha et. al [1], deadlock can never
occur.
Resource sharing becomes more complex when considering multiprocessor platforms instead of
uniprocessor platforms, because in multiprocessor systems the task-suspending and task-spinning
may come into play. Under spinning approach, tasks busy-wait in a tight loop or called “spin” to
the processor, while it is waiting for accessing a shared resource. Under suspending approach,
tasks relinquish their processor and suspend during the time waiting for a shared resource
accessing. There exist some protocols, which support both mechanisms, e.g. Multiprocessor Slack
Resource Policy (MSRP) [2] as a spin-based multiprocessor locking protocol as well as Distributed
Priority Ceiling Protocol (DPCP) [3] and Multiprocessor Priority Ceiling Protocol (MPCP) [4]
under suspending approach. Although, many suspension-based and spin-based locking protocols
have been designed and analyzed in the last years, it has been relatively little investigated, that
under which settings which one of the suspension-based and the spin-based locking protocols are
in general preferable. Therefore, this tradeoff has to be analyzed and some break-even
configurations should be determined. The only result in this area is published in [5], which
concludes that “blocking by suspending is rarely preferable to spinning (provided spinning can be
done in-cache, which we assume)”. However, the analysis in [5] is conducted only considering the
Flexible Multiprocessor Locking Protocol (FMLP).
In this thesis other locking protocols than FMLP will be taken into consideration and finally the
conditions that favor spin-based locking protocols over suspension-based locking protocols and
the other way around, will be specified. To this end, first a test-bed based on the platform
LITMUSRT [6] [7] will be set up and then those protocols will be tested under different settings of
properties such as number of processors, number of resource accesses per task, period of each task
and etc. to find the break-even configurations.

This study investigates the two major problems associated with the application of dynamic programming for the optimization of hybrid marine power trains.

In order to reduce the number of computations, a variant of dynamic programming is investigated, called the iterative dynamic programming. The implementation problems with iterative dynamic programming have also been investigated and solutions are proposed to tackle the problems.

The second issue is the loss of optimality due to the discretization of the continuous power train model. The introduction of different errors and their propagation through the optimization process is investigated. Multiple solutions are proposed in this area that aim to reduce the discretization errors without increasing the number of computations.

In order to test and experimentally verify the investigations, two test cases of hybrid power trains are defined.

  abstract = {Real-time systems are designed for applications in which response time is critical. As timing is a major property of such systems, proving timing correctness is of utter importance. To achieve this, a two-fold approach of timing analysis is traditionally involved: (i) worst-case execution time (WCET) analysis, which computes an upper bound on the execution time of a single job of a task running in isolation; and (ii) schedulability analysis using the WCET as the input, which determines whether multiple tasks are guaranteed to meet their deadlines. Formal models used for representing recurrent real-time tasks have traditionally been characterized by a collection of independent jobs that are released periodically. However, such a modeling may result in resource under-utilization in systems whose behaviors are not entirely periodic or independent. Examples are (i) multicore platforms where tasks share a communication fabric, like bus, for accesses to a shared memory beside processors; (ii) tasks with synchronization, where no two concurrent access to one shared resource are allowed to be in their critical section at the same time; and (iii) automotive systems, where tasks are linked to rotation (e.g., of the crankshaft, gears, or wheels). There, their activation rate is proportional to the angular velocity of a specific device. This dissertation presents multiple approaches towards designing scheduling algorithms and schedulability analysis for a variety of real-time systems with different characteristics.

  abstract = {Embedded/Cyber-physical systems have become popular in a wide range of application scenarios. Such systems are called real-time systems if they underlie strict timing constraints. To verify if such systems can meet their deadlines, the knowledge of an upper bound for a program's execution time is mandatory. This upper bound is also called worst-case execution time (WCET) and is estimated by static timing analyzers. Established optimizing compilers are not aware of the WCET as objective since they focus on the minimization of the average-case execution time (ACET). To overcome this obstacle, this thesis presents memory-based optimization techniques which focus on the reduction of the WCET of programs. All presented optimizations are integrated into the WCET-aware C Compiler (WCC) framework. Since the memory interface of a system often turns out to be a bottleneck which limits the performance of a system, the presented optimizations are applied to different levels of the memory hierarchy of a system. Starting within a CPU core, the instruction fetch buffer is the most tightly coupled memory which tries to provide the next few instructions to be executed. Optimization techniques are presented improving the efficiency of this buffer w.r.t. the WCET of a system. Instruction caches placed between the CPU core and the main memory try to speed up accesses to the main memory by storing local copies in fast small cache memories. In order to improve the efficiency of this part of the memory hierarchy, a memory content selection approach is introduced which improves the WCET of a program by improving the cache performance. Due to the fact that multi-task systems are employed in almost all domains, this thesis presents elaborate extensions to a compiler supporting the compilation and WCET-aware optimization of multi-task systems. These extensions are exploited to develop a number of novel optimizations for systems running multiple tasks. As first optimization, a WCET-driven software-based cache partitioning demonstrates the effectiveness of considering the WCET for the optimization of a set of tasks. Furthermore, many embedded systems integrate so-called scratchpad memories (SPM) as tightly coupled memories. An optimization approach for SPM allocation in a multi-task scenario is proposed. Besides, a holistic view of memory architecture compilation considers a number of memory-based WCET optimizations and presents approaches for a combined application. Existing compiler frameworks which are able to consider the WCET during optimization are limited to a particular hardware platform. In order to support multiple platforms, this thesis presents techniques to extend an existing WCET-aware compiler framework. Based on these extensions, a novel static cache locking optimization selects memory blocks which are statically locked into the instruction cache driven by WCET reductions. Applying these optimizations, the WCET of real-time applications can be reduced by about 35% to 48%.
