The diploma thesis is focused on the problematics of internal audits in a health care organisation. The aim of the thesis is to examine, which factors influence the approach of employees towards the system of internal audits in a specific health care organisation and how to optimalize this system. Key words are defined in the theoretical part and include these terms: organizational culture, engagement of employees, approach, motivation, communication and change. Different points of view are described with specification of how we approach them in the diploma thesis. We deal with internal audits in detail in connection with the systems of quality management in health care in the Czech Republic. We also briefly describe the relevant legislation with regard to Act No. 372/2011 Coll., on health services and conditions of their provision. In the analytical-research part we use the qualitative research to realize the aim of the diploma thesis. The output from the research are practical recommendations for further development of the team of internal auditors. Internal auditors have significant influence on the attitude of employees towards the whole system. The research shows the need of creating space for providing feedback and reflection as a tool for continual improvement of processess and their quality...

Mathematical optimization is applicable to nearly every scientific discipline. This thesis specifically focuses on optimization applications to digital communications and signal processing. Within the digital communications framework, the channel encoder attempts to encode a message from a source (the sender) in such a way that the channel decoder can utilize the encoding to correct errors in the message caused by the transmission over the channel. Low-density parity-check (LDPC) codes are an especially popular code for this purpose. Following the channel encoder in the digital communications framework, the modulator converts the encoded message bits to a physical waveform, which is sent over the channel and converted back to bits at the demodulator. The modulator and demodulator present special challenges for what is known as the two-antenna problem. The main results of this work are two algorithms related to the development of optimization methods for LDPC codes and the two-antenna problem. Current methods for optimization of LDPC codes analyze the degree distribution pair asymptotically as block length approaches infinity. This effectively ignores the discrete nature of the space of valid degree distribution pairs for LDPC codes of finite block length. While large codes are likely to conform reasonably well to the infinite block length analysis, shorter codes have no such guarantee. Chapter 2 more thoroughly introduces LDPC codes, and Chapter 3 presents and analyzes an algorithm for completely enumerating the space of all valid degree distribution pairs for a given block length, code rate, maximum variable node degree, and maximum check node degree. This algorithm is then demonstrated on an example LDPC code of finite block length. Finally, we discuss how the result of this algorithm can be utilized by discrete optimization routines to form novel methods for the optimization of small block length LDPC codes. In order to solve the two-antenna problem, which is introduced in greater detail in Chapter 2, it is necessary to obtain reliable estimates of the timing offset and channel gains caused by the transmission of the signal through the channel. The timing offset estimator can be formulated as an optimization problem, and an optimization method used to solve it was previously developed. However, this optimization method does not utilize gradient information, and as a result is inefficient. Chapter 4 presents and analyzes an improved gradient-based optimization method that solves the two-antenna problem much more efficiently.

On sait depuis vingt ans maintenant qu'un ordinateur quantique permettrait de résoudre en temps polynomial plusieurs problèmes considérés comme difficiles dans le modèle classique de calcul, comme la factorisation ou le logarithme discret. Entre autres, un tel ordinateur mettrait à mal tous les systèmes de chiffrement à clé publique actuellement utilisés en pratique, mais sa réalisation se heurte, entre autres, aux phénomènes de décohérence qui viennent entacher l'état des qubits qui le constituent. Pour protéger ces qubits, on utilise des codes correcteurs quantiques, qui doivent non seulement être performants mais aussi munis d'un décodage très rapide, sous peine de voir s'accumuler les erreurs plus vite qu'on ne peut les corriger. Une solution très prometteuse est fournie par des équivalents quantiques des codes LDPC (Low Density Parity Check, à matrice de parité creuse). Ces codes classiques offrent beaucoup d'avantages : ils sont faciles à générer, rapides à décoder (grâce à un algorithme de décodage itératif) et performants. Mais leur version quantique se heurte (entre autres) à deux problèmes. On peut voir un code quantique comme une paire de codes classiques, dont les matrices de parité sont orthogonales entre elles. Le premier problème consiste alors à construire deux « bons » codes qui vérifient cette propriété. L'autre vient du décodage : chaque ligne de la matrice de parité d'un des codes fournit un mot de code de poids faible pour le second code. En réalité, dans un code quantique, les erreurs correspondantes sont bénignes et n'affectent pas le système, mais il est difficile d'en tenir compte avec l'algorithme de décodage itératif usuel. On étudie dans un premier temps une construction existante, basée sur un produit de deux codes classiques. Cette construction, qui possède de bonnes propriétés théoriques (dimension et distance minimale), s'est avérée décevante dans les performances pratiques, qui s'expliquent par la structure particulière du code produit. Nous proposons ensuite plusieurs variantes de cette construction, possédant potentiellement de bonnes propriétés de correction. Ensuite, on étudie des codes dits q-Aires~: ce type de construction, inspiré des codes classiques, consiste à agrandir un code LDPC existant en augmentant la taille de son alphabet. Cette construction, qui s'applique à n'importe quel code quantique 2-Régulier (c'est-À-Dire dont les matrices de parité possèdent exactement deux 1 par colonne), a donné de très bonnes performances dans le cas particulier du code torique. Ce code bien connu se décode usuellement très bien avec un algorithme spécifique, mais mal avec l'algorithme usuel de propagation de croyances. Enfin, un équivalent quantique des codes spatialement couplés est proposé. Cette idée vient également du monde classique, où elle améliore de façon spectaculaire les performances des codes LDPC : le décodage s'effectue en temps quasi-Linéaire et atteint, de manière prouvée, la capacité des canaux symétriques à entrées binaires. Si dans le cas quantique, la preuve éventuelle reste encore à faire, certaines constructions spatialement couplées ont abouti à d'excellentes performances, bien au-Delà de toutes les autres constructions de codes LDPC quantiques proposées jusqu'à présent. / Quantum information is a developping field of study with various applications (in cryptography, fast computing, ...). Its basic element, the qubit, is volatile : any measurement changes its value. This also applies to unvolontary measurements due to an imperfect insulation (as seen in any practical setting). Unless we can detect and correct these modifications, any quantum computation is bound to fail. These unwanted modifications remind us of errors that can happen in the transmission of a (classical) message. These errors can be accounted for with an error-Correcting code. For quantum errors, we need to set quantum error-Correcting codes. In order to prevent the clotting of errors that cannot be compensated, these quantum error-Correcting codes need to be both efficient and fast. Among classical error-Correcting codes, Low Density Parity Check (LDPC) codes provide many perks: They are easy to create, fast to decode (with an iterative decoding algorithme, known as belief propagation) and close to optimal. Their quantum equivalents should then be good candidates, even if they present two major drawbacks (among other less important ones). A quantum error correction code can be seen as a combination of two classical codes, with orthogonal parity-Check matrices. The first issue is the building of two efficient codes with this property. The other is in the decoding: each row of the parity-Check matrix from one code gives a low-Weight codeword of the other code. In fact, with quantum codes, corresponding errors do no affect the system, but are difficult to account for with the usual iterative decoding algorithm. In the first place, this thesis studies an existing construction, based on the product of two classical codes. This construction has good theoritical properties (dimension and minimal distance), but has shown disappointing practical results, which are explained by the resulting code's structure. Several variations, which could have good theoritical properties are also analyzed but produce no usable results at this time. We then move to the study of q-Ary codes. This construction, derived from classical codes, is the enlargement of an existing LDPC code through the augmentation of its alphabet. It applies to any 2-Regular quantum code (meaning with parity-Check matrices that have exactly two ones per column) and gives good performance with the well-Known toric code, which can be easily decoded with its own specific algorithm (but not that easily with the usual belief-Propagation algorithm). Finally this thesis explores a quantum equivalent of spatially coupled codes, an idea also derived from the classical field, where it greatly enhances the performance of LDPC codes. A result which has been proven. If, in its quantum form, a proof is still not derived, some spatially-Coupled constructions have lead to excellent performance, well beyond other recent constuctions.

Oh My is a design and brand agency that has been developing CHECK, an accounting, billing, and time reporting system. CHECK has been developed to ease the billing and accounting process by making a front-shell system that is easier to use than the existing back-end economic system (Fortnox). To further enhance CHECK’s user experience, a need for a resource scheduling feature arose. The mission of this master thesis project is therefore to design a resource scheduling feature by going through the double diamond design process.  The double diamond design process consists of four phases, a discovering phase, a defining phase, a developing phase, and a delivering phase. The discovering phase consisted of a literature review, interviews, user observations, a market analysis, and workshops to discover the current resource scheduling market and Oh My’s resource scheduling needs. The defining phase consisted of collecting and sorting the information gathered in the previous phase, which were conducted by using a design specification. The developing phase was the creative phase where solutions were beginning to emerge through paper prototyping. The delivering phase was the iterative phase where user tests were conducted, and the design was changed and improved. The delivering phase contained 4 different user test that resulted in the final version of a resource planning system.

Two dimensional magnetic recording (TDMR) achieves high areal densities by reducing the size of a bit comparable to the size of the magnetic grains resulting in two dimensional (2D) inter symbol interference (ISI) and very high media noise. Therefore, it is critical to handle the media noise along with the 2D ISI detection. In this paper, we tune the generalized belief propagation (GBP) algorithm to handle the media noise seen in TDMR. We also provide an intuition into the nature of hard decisions provided by the GBP algorithm. The performance of the GBP algorithm is evaluated over a Voronoi based TDMR channel model where the soft outputs from the GBP algorithm are used by a belief propagation (BP) algorithm to decode low-density parity check (LDPC) codes.
