Thesis (MEng)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The focus of this thesis is position sensorless control of a transverse-laminated reluctance synchronous machine. Rotor position information is required for high-performance closedloop control of the reluctance synchronous machine and is conventionally supplied by unreliable hardware position resolvers. In addition a FPGA-based rapid prototyping system is completed as part of the research term for control of the machine drive system. For the first time the unified active- ux (AF) method is investigated and implemented for position sensorless control of the transverse-laminated reluctance synchronous machine in this study. The method is based on the torque equation of the machine and is basically the same for any AC machine. The estimation scheme is implemented for closed-loop position sensorless control from low- to rated speed in the entire rated load range with simulation and measured results confirming its capabilities. A number of characteristics of the machine (including generator operation) have implications for implementation of the active- ux (AF) method and are therefore investigated. Another position estimation method investigated is the arbitrary injection (AI) scheme which is derived to be completely machine parameter independent. The method simply requires a current progression at each calculation step allowing use of a smaller injection voltage. This method is implemented again on the reluctance synchronous machine and is shown to be capable of position sensorless current and speed control of the drive from standstill to rated speed with simulation and measured results. However, when the machine is operating above low speeds it is shown that this technique is only capable of position sensorless control at low loads. To deliver position sensorless control in the entire rated speed and load range a new hybrid controller scheme is designed and implemented. The hybrid scheme is speed and load dependent with hysteresis regions for stability at specific working points. The active- ux (AF) method is implemented in the low to rated speed range at medium to rated loads while the arbitrary injection (AI) method is implemented elsewhere. Measured results show that the scheme is capable of position sensorless control in the entire rated speed and load range with some limitations on dynamics. Because of the limitations on dynamics of the hybrid scheme an assisted fundamental model position estimation scheme was investigated. Simulation results show that this controller requires further investigation. / AFRIKAANSE OPSOMMING: Die fokus in hierdie tesis is die posisie-sensorlose beheer van 'n transvers-gelamineerde reluktansie sinchroonmasjien. Rotor posisie inligting word benodig vir geslote-lus beheer van die reluktansie sinchroonmasjien met ho e-werkverrigting, en word normaalweg deur onbetroubare hardeware sensors verskaf. As deel van die navorsings-termyn is 'n FPGAgebaseerde beheerstelsel vir die masjien stelsel voltooi. Die \aktiewe-vloed" posisie-afskattings metode is ondersoek en vir die eerste keer ge mplementeer vir posisie-sensorlose beheer van die transvers-gelamineerde reluktansie sinchroonmasjien. Die metode is dieselfde in konsep vir alle WS masjiene en word basseer op die vergelyking vir wringkrag van die masjien. Vollas geslote-lus posisie-sensorlose beheer van die masjien in die lae tot ho e spoedbereik is suksesvol ge mplementeer met simulasie en gemete resultate. Verkskeie inherente eienskappe van die masjien het implikasies vir gebruik van die \aktiewe-vloed" metode (insluitend generator werking) en is dus ondersoek. Die \arbitr^ere injeksie" metode wat afgelei is om onafhanklik van masjien parameters te wees is ook odersoek. Hierdie metode verlang slegs 'n stroom-afgeleide by elke tydstip en benodig dus 'n kleiner injeksie-spanning. Hierdie metode is weer ge mplementeer op die reluktansie sinchroon masjien met suksesvolle posisie-sensorlose beheer in die hele spoed bereik getoon in simulasie en praktiese resultate. Dit word egter getoon dat hierdie metode slegs onder lae-las toestande posisie sensorlose beheer bo lae-spoed kan bewerkstellig. Ten einde posisie-sensorlose beheer in die hele spoed en wringkrag bereik te verkry is 'n nuwe hibriede beheerskema ontwerp en ge mplementeer. Die skema is spoed en las afhanklik met histerese vir stabiliteit by 'n spesi eke werkpunt. Die \aktiewe-vloed" metode word gebruik bo lae spoed teen 'n minimum las terwyl die \arbitr^ere injeksie" andersins ge mplementeer word. Gemete resultate toon dat die skema posisie-sensorlose beheer van die masjien in die hele spoed en las bereik toelaat met sommige beperkings op dinamika. Met inagneming van die beperkings op die hibriede metode is 'n ondersteunde fundamentele model afskattingskema ondersoek. Simulasie resulate toon dat hierdie beheerder verdere ondersoek benodig.

Esta pesquisa analisa em perspectiva compara entre Moçambique e Brasil, a estrutura e o funcionamento das instituições do setor da administração da justiça, com ênfase nos procedimentos processuais adotados no âmbito da investigação criminal e/ou inquérito policial, e na decretação da prisão preventiva. A finalidade desta comparação é averiguar as diferenças e semelhanças, e aferir as causas das prisões arbitrárias (prisões preventivas ou provisórias com prazos esgotados). Tratou-se de investigar as estratégias no âmbito da prevenção e do combate ao crime, indagando o posicionamento das instituições governamentais, dos agentes do controle penal (Polícias, Ministério Público, Poderes Judiciários e Agentes da Ordem dos Advogados), assim como às políticas de reclusão e das organizações da sociedade civil que zelam pela observância dos direitos humanos. Em termos metodológicos, optou-se por uma abordagem qualitativa coadjuvada pelo método quantitativo numa perspectiva comparada. Os dados foram coletados por meio da utilização das técnicas de observação participante, análise documental e a revisão bibliográfica. No que respeita ao instrumento de recolha de dado foi usada a técnica de entrevista. / This research analyzes in perspective compares between Mozambique and Brazil, the structure and the functioning of the justice administration institutions sector, with an emphasis on procedures adopted in the context of a criminal investigation and/or Police investigation, and the declaring of pre-trial detention, whose purpose is to assess the differences and similarities, and assess the causes of arbitrary arrests (detention orders or interim deadlines exhausted). It was to investigate strategies within the framework of the prevention and combating of crime, questioning the placement of governmental institutions, the agents of criminal control (Police, prosecutors, Judiciary Powers and Agents of the Order of Lawyers), as well as the policies of detention and of civil society organizations that shall ensure the observance of Human Rights.

The data were collected through the following techniques: participant observation, document analysis and the literature review. In the case of instruments for the collection of data was used to interview technique.

Le droit ne se réduit pas aux règles. Que cet ancien adage paraisse aujourd’hui sibyllin montre la difficulté des juristes face à ce qu’il faut appeler l’anomie. Le pouvoir confié à une autorité de surmonter cette absence de règles provoque l’émergence de l’arbitraire en droit. Depuis l’Antiquité, ses fonctions répressives et administratives témoignent de son utilité indéfectible. Sous l’emprise du déterminisme juridique intégral d’un Dieu (VIIIe-XIIIe) ou d’un Législateur (XVIIIe-XXe), l’arbitraire se réduit à l’interprétation des normes omniprésentes. Il peut également former une voie de droit extraordinaire en complément des règles fixes (XIIIe-XVIIIe). Son apogée comme principe général de gouvernement voire de répression n’est atteinte qu’à l’occasion du profond bouleversement moderne (XVIe). À travers ces variations, trois formes de légalité se côtoient et proposent les conditions du choix d’un arbitraire légal. / Law is not reducible to rules. The fact that this ancient adage now sounds intriguing points out jurist’s difficulties to face what must be called anomie. Arbitrariness refers to the power given to one authority to overcome this absence of rules. Since Antiquity, repressive and administrative functions shows its irreducible utility. Under the empire of an integral determinism of God (VIIIe-XIIIe) or a Legislator (XVIIIe-XXe), arbitrariness is confined to interprete omnipresent norms. It can also provide extraordinary means in complement of fixed rules (XIIIe-XVIIIe). Its apogee as general principle of government or punishment is only reached by the modern upheaval (XVIe). Through its variations, three forms of legality coexists and reveals the conditions surrounding the choice of a legal arbitrariness.

The main result of this thesis is that we prove certain versions of Ilmanen's lemmma. That means - given semiconvex (or locally semiconvex) function f1 and semiconcave (or locally semiconcave) function f2 such that f1 ≤ f2 we find a function f such that f1 ≤ f ≤ f2 and f is both semiconvex and semiconcave (or locally uniformly differentiable). We also give characterization (via a new variation) of those functions which are the difference of two ω-nondecreasing functions 1

Après avoir identifié l’emploi du genre masculin en français et l’utilisation du mot « homme » comme « dispositifs de désinformation », une recherche-action, menée pendant 10 ans dans une optique de déontologie journalistique sur le moyen d’informer à propos des femmes comme des hommes, en utilisant la langue française, m’a conduite à adopter une marque graphique qui donne forme au genre commun, du point de vue morphosyntaxique. C’est le point médian unique nommé « point de l’altérité (·)» pour son potentiel de reconnaissance de la diversité humaine. Le compte-rendu de cette recherche et sa poursuite en sciences de l’information et de la communication m’ont permis d’élaborer des procédures d’analyses issues de la linguistique fonctionnelle et de la grammaire classique dans ce que j’ai nommé le champ de la « francographie ». L’analyse d’une affiche Tisséo (transport en commun toulousain) a servi de matrice méthodologique pour déployer des mesures de genre en utilisant les notions de féminin /masculin/ hors genre (ex : adverbes, prépositions…), genre arbitraire (ex : une chaise, un tabouret, une personne…) / genre motivé (ex : un ou une instit, un ou une prof…) et genre apparent (ex : instituteur, institutrice, avocat, avocate…) / genre non apparent (ex : journaliste, architecte, notaire…). Enfin, des propositions didactiques sont présentées comme pratique de « transmutation des valeurs ». / After having identified the use of the masculine gender in the French language and the use of the word "man" as "a tool of disinformation", I conducted a research-action, during 10 years, within an optic of journalistic ethics, on the means used in the French language to inform about women as well as men, which led me to adopt a graphic mark (·) the single median dot, named 'dot of otherness' for its potential recognition of human diversity, so as to signify a common gender identification. This research’s review and its continuation within information and communication sciences have enabled me to develop functional linguistic and classical grammar analytical procedures within the scope of what I define as «francography». I used the analysis of a Tisséo poster (Toulouse public transportation) as a methodological matrix, to develop and display parity measures using the notions of feminine / masculine / outbound genre, arbitrary / semantically motivated and apparent / non apparent gender (read the above examples in French language). Finally didactical proposals are presented as a new way of "transmutation of values".

This study explores perceptions of women’s freedom of movement since the 27 May 2015 Constitutional Court ruling CCZ 15/15, outlawing arbitrary arrests of women after dusk on grounds of loitering with intent to solicit for prostitution, focusing on Zimbabwe’s Avenues community. It traces issues surrounding women’s mobility under patriarchy since colonialism which through the 1960 Vagrancy Act marked the inception of its legal regulation premising stereotypic arrests by state agents. Guided by Pragmatic and Feminist philosophy the researcher adopts a Mixed Method Strategy to gather new knowledge on the complex issue. Employing Radical Feminist Theory under Feminism it critiques government efforts and their efficacy towards ensuring gender equality in mobility. The study argues that while useful legal mechanisms and laws have been adopted to enable women’s right to mobility, ideological and physical challenges continue to hamper this realisation. Empowering the Gender Commission with binding powers, ensuring sufficient security in public areas and educating women about their rights are some recommendations proffered to address challenges faced by women in the exercise of their right to movement. / Development Studies / M.A. (Development Studies)
