This thesis presents various studies on energy efficient design of wireless networks. It starts with a survey on recent shortest path based energy efficient routing algorithms developed for ad hoc and sensor networks, making a comprehensive classification for these algorithms. In addition to energy efficient design, sustainable and environmentally friendly deployment of wireless networks demands increased use of renewable energy. However, this calls for novel design principles to efficiently utilize the variation in the availability of the energy. The thesis continues with an investigation of state-of-the-art resource management and scheduling algorithms developed for energy harvesting wireless sensor networks. Building on the stateof- the-art, the main contribution of this thesis is to formulate and solve a utility maximizing scheduling problem in a multiuser broadcast channel with an energy harvesting transmitter. The goal is to determine the optimal power and time allocations to users between energy arrivals. The structural properties of the problem are analyzed, and its biconvexity is proved. A Block Coordinate Descent (BCD) based algorithm is developed to obtain the optimal solution. Two simple and computationally scalable heuristics, PTF and ProNTO, which mimic the characteristics of the optimal policy, are proposed. Finally, an online algorithm, PTF-On,that will bypass the need for offline knowledge about the energy harvesting statistics, is developed. PTF-On uses a Kalman filter based energy harvesting prediction algorithm, developed in this thesis, to predict the energy that will arrive in the future.

Consulting with the public on planning issues has become an endeavour formalized throughout Western democracies over the past half-century. However, there remains a dichotomy between the legislative minimums for this part of the planning process and the extraordinary efforts of some municipalities. Inefficiencies emerge as attempts are made by many municipalities to implement the contributions received, exposing the potentially different objectives held by each of the major consultation players. Academics suggest that the rationale for consultation appears to have advanced to the point where its value is beyond question, but that the means and frequency for its conduct are not. The literature on the subject is further split between that which focuses on the process of consultation and that which centres on its outcomes. Correspondingly, the fairness of consultation exercises can be viewed from the procedural and distributive points of view. To date, academic study in this field has largely been conducted along qualitative lines. Using a combination of questionnaires, interviews and a focus group to triangulate data received from the major players, an answer was sought to the hypothesis that consultation players possess distinct objectives for this planning exercise. The results indicated that planners and the public do subscribe to separate views for the purpose of consultation, which bias their paradigms of the other parties. Isolating other factors regarding each of these cohort groups further suggested that time, geography, and education often limit the participation of citizens, while planners feel constrained by time, apathy among participants, the political processes and certain fiscal realities. Therefore, changes to planning legislation are recommended that would indirectly reduce the burden for each of the major players by conducting anticipatory consultation. Such measures would reverse the onus of participating while requiring a lesser investment of staff and resources from municipalities. Future research would test the validity of this approach and engage political figures as the final cohort in the triangle of planning participation.

Employment of the multiple-antenna transmitters/receivers in communication systems is known as a promising solution to provide high-data-rate wireless links. In the multi-user environments, the problems of signaling and fairness for multi-antenna systems have emerged as challenging problems. This dissertation deals with these problems in several multi-antenna multi-user scenarios. In part one, a simple signaling method for the multi-antenna broadcast channels is proposed. This method reduces the MIMO broadcast system to a set of parallel channels. The proposed scheme has several desirable features in terms of: (i) accommodating users with different number of receive antennas, (ii) exploiting multi-user diversity, and (iii) requiring low feedback rate. The simulation results and analytical evaluations indicate that the achieved sum-rate is close to the sum-capacity of the underlying broadcast channel. In part two, for multiple-antenna systems with two transmitters and two receivers, a new non-cooperative scenario of data communication is studied in which each receiver receives data from both transmitters. For such a scenario, a signaling scheme is proposed which decomposes the system into two broadcast or two multi-access sub-channels. Using the decomposition scheme, it is shown that this signaling scenario outperforms the other known non-cooperative schemes in terms of the achievable multiplexing gain. In particular for some special cases, the achieved multiplexing gain is the same as the multiplexing gain of the system, where the full cooperation is provided between the transmitters and/or between the receivers. Part three investigates the problem of fairness for a class of systems for which a subset of the capacity region, which includes the sum-capacity facets, forms a polymatroid structure. The main purpose is to find a point on the sum-capacity facet which satisfies a notion of fairness among active users. This problem is addressed in the cases where the complexity of achieving interior points is not feasible, and where the complexity of achieving interior points is feasible. In part four, $K$-user memoryless interference channels are considered; where each receiver sequentially decodes the data of a subset of transmitters before it decodes the data of the designated transmitter. A greedy algorithm is developed to find the users which are decoded at each receiver and the corresponding decoding order such that the minimum rate of the users is maximized. It is proven that the proposed algorithm is optimal. The results of the parts three and four are presented for general channels which include the multiple-antenna systems as special cases.

This thesis addresses the problem of reactive power scheduling in a power system with several areas controlled by independent transmission system operators (TSOs). To design a fair method for optimizing the control settings in the interconnected multi-TSO system, two types of schemes are developed. First, a centralized multi-TSO optimization scheme is introduced, and it is shown that this scheme has some properties of fairness in the economic sense. Second, the problem is addressed through a decentralized optimization scheme with no information exchange between the TSOs. In this framework, each TSO assumes an external network equivalent in place of its neighboring TSOs and optimizes the objective function corresponding to its own control area regardless of the impact that its choice may have on the other TSOs. The thesis presents simulation results obtained with the IEEE 39 bus system and IEEE 118 bus systems partitioned between three TSOs. It also presents some results for a UCTE-like 4141 bus system with seven TSOs. The decentralized control scheme is applied to both time-invariant and time-varying power systems. Nearly optimal performance is obtained in those contexts.

This doctoral thesis analyzes the systematic role of Kant's conception of happiness in his moral, legal and political theory. Although many of his conclusions and arguments are directly or indirectly influenced by his conception of human happiness, Kant's underlying assumptions are rarely overtly discussed or given much detail in his works. Kant also provides different and apparently incompatible definitions of happiness. This research explores the domains of Kant's practical philosophy in which his conception of happiness plays a systematic role: the relation between the natural need of human beings to pursue happiness and the ends-oriented structure of the human will; Kant's anti-eudaimonism in ethical theory; Kant's claim that we have an indirect duty to promote our own happiness and the problem that under certain circumstances, the indeterminacy of happiness makes it not irrational to choose short term satisfaction at the costs of one's overall, long term happiness, given Kant's conception of non-moral choice as expectation of pleasure; Kant's justification of the duty to adopt the happiness of others as our ends (the duty of beneficence) and the latitude and eventual demandingness of this duty; finally, since Kant also subsumes subsistence needs and welfare under the concept of happiness of individuals, I also engage with the question of state provision for the poor in the Kantian Rechtsstaat and explore Kant's conception of equity or fairness (Billigkeit) as an alternative to the traditional minimalist and the welfare interpretations of the Kantian state.

Purpose The thesis purpose is to contribute with understanding about managers’ opinions about how to handle deviations caused by unit interdependence. Methodology Qualitative data has been gathered to this exploratory study by semi-structured interviews with 14 managers within the R&D, purchasing and production units at Scania, Södertälje. The result has been interpreted and analyzed by dividing the managers in five smaller groups.  Result from analyzing empirical findings It is found in the analysis that the largest part of the managers in this study seem not to believe it is worth striving for excellence through procedural justice. Reoccurring similarities in opinion between managers is that visualization, dialogue, clear responsibility and less tolerance towards deviations are needed for handling and preventing deviations. Differences in opinion are primarily related to how costs occurred from deviations should be allocated and the purpose with such reallocation. Most managers express a strong concern about undesired behavior developed by a control system where a causing unit always should take the effect from a deviation. However, all managers state that costs occurred from deviations due to interdependence with a external supplier should be invoiced to the supplier.  Conclusion The concern about undesired behavior that may be developed by the way of handling and preventing deviation is strongly mediated by the managers. Instead of handling deviations by justly reallocating effects according to the controllability principle it is perceived as more important to extend the areas of responsibility and increase consciousness between interdependent units through improved dialogue and cross-functional transparency. One should therefore not seek equitable allocation of impacts and cost of devices in dealing with anomalies of this type.
