Risberg, Patrik. "IT Track or People Track?" Thesis, University of Gävle, Department of Business Administration and Economics, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:hig:diva-73.
Pełny tekst źródłaThis thesis deals with knowledge management at companies in the Falun-Borlänge region. The purpose is to create better understanding of which path companies have chosen and why, respectively. A qualitative survey seeks to discover if companies have chosen IT track or people track. This is a practical and useful model for an evaluative study. In the same context, a number of important models for evaluating knowledge management are presented.
The result shows that the companies provide a multitude of training within several frameworks. Education is mostly provided in a traditional manner but there are many examples of interactive state-of-the-art training. Furthermore, most of the companies primarily focus upon people and processes, but some focus at technical facilities as well. In some cases are the technical frameworks used for support of core processes.

Pełny tekst źródłaMore often than not however, the idea of a good drawing, regardless of its purpose, coincides with having no edge crossings or having very few crossings. Unfortunately, whichever of the numerous drawing styles one considers, a problem requiring a crossing minimization of sorts will, almost certainly, be NP -hard. The theory of fixed parameter tractability (FPT) provides a new and promising approach for coping with intractable problems. In the first part of this thesis we apply algorithmic techniques developed in this theory to well-known graph drawing problems. In particular, we contribute efficient FPT algorithms for crossing minimization and planarization problems concerning the 2-layer drawing style.
In the second part of this thesis we introduce and comprehensively study so-called track layouts of graphs and their subdivisions. A relationship between this combinatorial structure and several well-known types of graph layouts is established, leading to a number of new results. For example, our study of track layouts of bounded treewidth graphs settles an open problem due to Ganley and Heath (2001) regarding queue layouts of such graphs. Moreover, the study also establishes that graphs of bounded treewidth have three-dimensional straight-line grid drawings with linear volume.
Through the study of track layouts of subdivisions, we determine that every graph with n vertices and m edges has a three-dimensional polyline grid drawing with the vertices on a rectangular prism, O (n + m log n) volume and O (log n) bends per edge.

Pełny tekst źródłaIn many Western European countries, the method of timber harvesting has changed from the use of chain saws to a mechanized harvesting system known as Cut-To-Length method. This cut to length method is based on a two-machine solution – a harvester that folds, branches and cuts trees according to pre-defined lengths, and a forwarder that transports logs to a loading area from where it is further transported to a processing facility. In order to develop forest machines that is gentler to the ground, a thorough understanding of the terrain and the vehicle’s traction unit is required. The main focus of this project is on the tracked forest forwarders.In this project, the track soil interaction covers issues like rutting, compaction, ground pressure, shearing, traction and drawbar pull. The rut depth is one of the important factors to determine the vehicle performance and damages caused to the ground and vegetation. Measurement and characterization of the mechanical properties of a multilayer soil is quite a complex task. The two most commonly used methods to measure the soil mechanical properties are the Bevameter technique and the Cone penetrometer technique, of which the Bevameter technique is comparatively less efficient for characterizing the Nordic forest terrain as the forest soil is not homogenous.Different semi-empirical WES models and parametric models are used for the determining the ground pressure, rut depth, tractive force, motion resistance and drawbar pull for the wheeled and tracked vehicles. The calculations were performed for a medium sized forwarder equipped with three different types of tracks mounted on bogie wheels on three types of terrain conditions under loaded and unloaded conditions. A comparison of the wheeled and tracked vehicle performance is also made. The results obtained from the theoretical calculations are compared with the test data from a full scale field test. The field test data include ground pressure, soil penetration and rut depth data measured on the forwarder with and without load.Adams for Tracked vehicles (ATV) plugin is a tool primarily developed for performing dynamic simulations of tracked equipment. The pros and cons of the software and it’s suitability to be used for the track soil interaction modeling of forestry machines is discussed in this report.

Pełny tekst źródłaThe increasing availability of powerful yet relatively inexpensive data acquisition and processing techniques has precipitated a radical reappraisal of the methods used to capture, manipulate and store data of all kinds. Some of the recently introduced recording systems can be used both for fast data capture and for high capacity archival/back-up applications - effectively bridging a long-standing divide between these two formerly diverse aspects of data recording and processing. This paper offers a brief overview of a new technology known as micro-track recording, and suggests ways in which system designers and integrators may take full advantage of its important new facilities and features.

Pełny tekst źródłaSimulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented. The model also includes representation of switches, sensors, and trains. In addition, a configurable prototype simulator is designed and implemented for a model railroad system. The experience gained in this project is documented in the report and is presented as guidelines for developing simulators for track-based systems.

If a worker is an able manager, the firm will lose valuable production time by slow promotion. However, slower promotion allows more information to be revealed for a given expenditure. Different track lengths are created depending on the firm's initial assessment of managerial competence.

Licentiate thesis, KTH, School of Architecture and the Built Environment (ABE), 2007. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-4560.
Pełny tekst źródłaRailway transportation is showing a substantial increase. Investments in new infrastructure, new fast and comfortable vehicles, and high frequency of service are important factors behind the increase.
Infrastructure configuration and timetable construction play important roles in the competitiveness of railway transportation. This is especially true on single-track lines where the travel times and other timetable related parameters are severely restricted by crossings (train meetings). The crossings also make the lines’ operation more sensitive to disturbances.
Since the major part of the Swedish railway network is single-track it is of great interest to examine the relationships between operation properties, such as travel times and reliability, and infrastructure configuration on single-track lines. The crossings are the core feature of single-track operation and this thesis focuses on the crossing time, i.e. the time loss that occurs in crossing situations.
A simplified analytical model, SAMFOST, has been developed to calculate the crossing time as a function of infrastructure configuration, vehicle properties, timetable and delays for two crossing trains. The effect of possible surrounding trains is not taken into account and all kinds of congestion effects are thus excluded from evaluation. SAMFOST has been successfully validated against the simulation tool RailSys, which shows that this type of simplified model is accurate in non-congested situations.
A great advantage of disregarding congested situations is that analysis is independent of timetable assumptions. The model also explicitly shows the effect of punctuality, which is of particular importance on single-track lines where the interdependencies between trains are strengthened by the crossings.
For the same reason, the timetable is severely constrained. Nonetheless, there is often a need for changes of the timetable (crossing pattern). The thesis proposes three simple measures of timetable flexibility, all based on assigned crossing time requirements. Together, these measures can be used to evaluate how infrastructure configuration, vehicle properties, punctuality etc affect possibilities to alter the timetable.
As an example of its application, SAMFOST has been used to evaluate the effect of shorter inter-station distance, partial double-track and combined crossing and passenger stop. These measures affect the operational properties quite differently.
More crossing stations result in a minor decrease in travel time (lower mean crossing time) but significantly higher reliability (lower crossing time variance). These effects are independent of punctuality, which is a valuable property.
A partial double-track results in shorter travel times and in some cases also higher reliability. Both effects are strongly dependent on punctuality and high punctuality is needed to achieve high effects.
A combined crossing and passenger stop results in a situation similar to that of a partial double-track. In this case it is important to point out that the assignment of time supplements in the timetable should be directly correlated to punctuality in order to achieve good operation.
