In this dissertation we discuss various results for spaces that are wild, i.e. not locally simply connected. We first discuss periodic properties of maps from a given space to itself, similar to Sharkovskii's Theorem for interval maps. We study many non-locally connected spaces and show that some have periodic structure either identical or related to Sharkovskii's result, while others have essentially no restrictions on the periodic structure. We next consider embeddings of solenoids together with their complements in three space. We differentiate solenoid complements via both algebraic and geometric means, and show that every solenoid has an unknotted embedding with Abelian fundamental group, as well as infinitely many inequivalent knotted embeddings with non-Abelian fundamental group. We end by discussing Peano continua, particularly considering subsets where the space is or is not locally simply connected. We present reduced forms for homotopy types of Peano continua, and provide a few applications of these results.

Agricultural vehicles use electronic control units (ECUs) as control system. HistoricallyECUs have only been equipped with a minimum of features. With therecent progress in electronics, which have made components faster, smaller andcheaper, the trend is now to integrate more advanced functionality into the ECUs. Agricultural vehicles are present all over the world and they have to operateunder a wide variety of conditions. This put high requirements on the system andit is critical that a modern ECU can detect and locate errors. For an ECU to beable to operate on a world-wide market it is required to be flexible, expandableand robust. In addition to these requirements it is also wanted that an ECU havea long lifespan and a low cost. In this thesis different problems that modern ECUs have to face are investigated.Suggestions of how to solve these problems are also presented. Thereare two focuses in the thesis, 1) how ECUs can acquire information from its inputs/outputs; and 2) the requirements of the ECU hardware. This thesis does not aim to deliver a fully specified system description butrather to provide an overview of how an ECU can be designed and which problemsthat it has to face. A selection of areas of ECU design which are investigated in this thesis are,1) typical inputs/outputs; 2) analog-to-digital converters and their application; 3)how multiplexers can be used; 4) requirements of general purpose inputs/outputs(GPIO); 5) monitoring of a controller area network (CAN); 6) power-supply requirementand monitoring; 7) monitoring of the vehicle’s battery; 8) memory; 9)requirement of the microcontroller (MCU);Agricultural vehicles use electronic control units (ECUs) as control system.

We study two topics on surface diffeomorphisms, their mapping classes and dynamics. For the mapping classes of a punctured disc, we study the $\ZxZ$ subgroups of the fundamental groups of the corresponding mapping tori. An application is the proof of the fact that a satellite knot with braid pattern is prime. For the mapping classes of the disc minus a Cantor set, we study a special type of reducible mapping class. This has direct application on the embeddings of solenoids in $\mathbb{S}^3$. We also give some examples of other types of mapping classes of the disc minus a Cantor set. For the dynamics of surface diffeomorphisms, we prove three formulas for computing the topological pressure of a $C^1$-generic conservative diffeomorphism with no dominated splitting and show the continuity of topological pressure with respect to these diffeomorphisms. We prove for these generic diffeomorphisms that there is no equilibrium states with positive measure theoretic entropy. In particular, for hyperbolic potentials, there are no equilibrium states. For $C^1$ generic conservative diffeomorphisms on compact surfaces with no dominated splitting and $\phi_m(x):=-\frac{1}{m}\log \Vert D_x f^m\Vert, m \in \mathbb{N}$, we show that there exist equilibrium states with zero entropy and there exists a transition point $t_0$ for the one parameter family $\lbrace t \phi_m\rbrace_{t\geq 0}$, such that there is no equilibrium states for $ t \in [0, t_0)$ and there is an equilibrium state for $t \in [t_0,+\infty)$.
