This thesis studies undefined behavior arising in systems programming languages such as C/C++. Undefined behavior bugs lead to unpredictable and subtle systems behavior, and their effects can be further amplified by compiler optimizations. Undefined behavior bugs are present in many systems, including the Linux kernel and the Postgres database. The consequences range from incorrect functionality to missing security checks. This thesis proposes a formal and practical approach, which finds undefined behavior bugs by finding "unstable code" in terms of optimizations that leverage undefined behavior. Using this approach, we introduce a new static checker called STACK that precisely identifies undefined behavior bugs. Applying STACK to widely used systems has uncovered 161 new bugs that have been confirmed and fixed by developers.

In this thesis, we explore full memory safety and the various intricacies involved. We analyze existing memory safety techniques in both hardware and software and their many different goals. This task involves determining the limits of the protections guaranteed by these different protection systems, regardless of whether they were explicitly or implicitly stated. It is demonstrated that the common software technique of protecting only allocation bounds does not provide nearly enough of a barrier for attackers. Then, we go beyond particular schemes and examine the limitations of languages, C in particular. We discover many corner cases and ambiguities that prevent even the best possible protection system from providing full memory safety in the context of the C language specification. We also collect some results for the prevalence of these issues, present approaches to further analyze them, and consider how they might extend into other languages or systems.

Texto completoProjektet representerar en oavslutad arbetsprocess där hemmet och bostadens rum undersöks och ifrågasätts. Projektets ambition är att analysera och utvärdera idén om bostaden, med en övertygelse om att det inte finns någon objektiv sanning för hur vi ska leva. Bostaden som vi ser den är en social konstruktion, där kärnfamiljen är normen för bostadens utformning. Verkligheten visar något annat. Hur kan vi skapa rum som är mer generella i sin användning? Processen är en undersökning kring hur arkitektoniska objekt generar en bostads-typologi som är mer öppen för tolkning. En öppen yta definierad av arkitektoniska komponenter, skapar ett oavslutat broderi av specifika rumsliga situationer, zoner och kompositioner. Det vardagliga livets estetik uppstår mot en abstrakt bakgrund.

Beta-adrenergic agonists (βAA) are administered during the final weeks of the beef production system to improve efficiency and increase meat yield. Welfare concerns linked to the administration of βAA have garnered significant attention in recent years due to anecdotal reports of increased mortality during βAA feeding periods and cattle without obvious disease or injury having difficulty walking at abattoirs being overrepresented in cattle fed βAA. Thomson et al. (2015) reported 2 events where cattle were distressed, became non-responsive to handling, sloughed hoof walls and were euthanized while in lairage at the abattoir. Consistent blood abnormalities in euthanized cattle included elevated blood lactate (25.6 mmol/L; ref. range: < 4-5) and creatine kinase (CK; 6,890 U/L, ref. range: 159- 332). Although no causal relationship had been established, dialogues among groups of packers, animal scientists, and welfare experts implicating the βAA zilpaterol hydrochloride (ZIL; Zilmax®, Merck Animal Health, Desoto, KS) as one possible etiology resulted in a major beef packer announcing plans to stop accepting cattle fed ZIL. Consequently, Merck announced a self-imposed suspension of ZIL sales in U.S. and Canadian markets until further research could be conducted to investigate the manner. Utilization of technologies such as βAA are imperative to meeting the demands of a growing world population and verdicts regarding such technologies, including their impact on animal welfare, should be based on scientific merit. The first objective of this research was to evaluate the effect of shade on performance and animal well-being in cattle fed ZIL. The second objective was to characterize the clinical description and hematological profile of fatigued cattle presented to abattoirs. The third objective was to evaluate the effects of handling intensity during shipment for slaughter in cattle fed a βAA. The fourth objective was to evaluate the effects of βAA administration on performance and physiological response to different handling intensities during shipping for slaughter. Shade provision reduced open-mouth breathing and increased dry matter intake and dressing percentage. Fatigued cattle observed at abattoirs had increased respiratory rates and muscle tremors, although blood parameters were relatively normal compared to their cohorts. Metabolic acidosis, a precursor for Fatigued Cattle Syndrome, was observed in cattle exposed to aggressive handling regardless of βAA status. This research confirms the improved growth performance of cattle fed βAA and highlights the improvement of animal welfare through shade provision and low-stress handling in heavy-weight feedlot cattle.

Our work will take into account the singularity of language of one child with psychotic functioning, where there is not one permanent, centralizer axle of speech. In this case the speech is derived without direction. We will seek to demonstrate the peculiarities of such functioning, presenting certain crucial moments in the curing of this child, such as the construction of images and stories that, in some way, propitiate the unification of the subject by organizing it and pointing to its underlying causes.

Texto completoJordens resurser är begränsade; med den hastighet som mänskligheten använder jordens resurser idag, skulle vi behöva 1,5 gånger jordens återhämtningsförmåga för att kompensera för det vi använder. Råmaterial har sedan länge brutits från berggrunden, vilket påverkar jorden på ett negativt sätt. Om vi istället skulle kunna använda material och produkter som cirkulerar i vårt samhälle, men inte används och därmed betraktas som avfall, skulle traditionell materialutvinning kunna ersättas med urban mining. Tänk vad som skulle hända om jordens resurser i framtiden begränsas genom lagar och regler; materialutvinning som det är känt idag inte skulle tillåtas och det då skulle finnas ett behov att samla resurser på ett annat sätt, ett idag okänt sätt. Världen förändras ständigt vilket resulterar i det faktum att det alltid kommer att finnas outforskade områden som måste definieras och utvecklas för att kunna hantera dessa förändringar i framtiden. Urban mining är ett sådant outforskat område och därför finns det ett behov av att skapa en process för att definiera segmentet och på så vis kunna utveckla produkter och tjänster inom området. Resultatet av denna uppsats är därför rekommendationer för hur en allmän design process kan skräddarsys och implementeras för innovativ utveckling i odefinierade områden. Resultatet uppnås genom att analysera ett utvecklingsprojekt, som fokuserar på forskningsområdet urban mining, som en fallstudie, samt att studera designprocesser i teorin. Undersökningen genomförs med ett explorativt tillvägagångssätt genom att utföra observationer inom ämnet urban mining. Arbetet visar att drivfaktorer och trender för urban mining existerar och att det finns ett framtida behov att utforska och dra fördel av denna marknad. Resultatet visar också att de viktigaste egenskaperna hos design processen vid utveckling inom okända områden är det faktum att forskningsområdet kräver ännu större fokus på att definiera området, jämfört med kända forskningsområden.
Wilke, Pierre. "Compilation formellement vérifiée de code C de bas-niveau". Thesis, Rennes 1, 2016. http://www.theses.fr/2016REN1S088/document.
Texto completoThis thesis presents an extension of the CompCert compiler that aims at providing formal guarantees about the compilation of more programs than CompCert does. The CompCert compiler compiles C code into assembly code for various architectures and provides formal guarantees about the behaviour of the compiled assembly program. It states that whenever the C program has a defined semantics, the generated assembly program behaves similarly. However, the theorem does not provide any guarantee when the source program has undefined semantics, or, in C parlance, when it exhibits undefined behaviour, even though those behaviours actually happen in real-world code. This thesis exhibits a number of C idioms, that occur in real-life code and whose behaviour is undefined according to the C standard. Because they happen in real programs, our goal is to enhance the CompCert verified compiler so that it also provides formal guarantees for those programs. To that end, we propose a memory model for CompCert that makes pointer arithmetic and uninitialised data manipulation defined, introducing a notion of symbolic values that capture the meaning of otherwise undefined idioms. We adapt the whole memory model of CompCert with this new formalism and adapt the semantics of all the intermediate languages. We prove that our enhanced semantics subsumes that of CompCert. Moreover, we show that these symbolic semantics capture the behaviour of the previously undefined C idioms. The proof of semantic preservation from CompCert needs to be reworked to cope with our model. We therefore generalize important proof techniques such as memory injections, which enable us to port the whole proof of CompCert to our new memory model, therefore providing formal guarantees for more programs

Texto completoThe knowledge implies a predisposition to the knowledge, that is the possibility of the relation between a (knowing) subject and a (knowable) object. On the other hand, there is an established fact, which is the knowledge which has de facto place : the common, ordinary, always incomplete knowledge, to which the man is continuously to have access or to be having access. The real knowledge – full and whole – is situated outside of this ordinary cognitive domain ; exteriority which implies a present indisposition to have access there. The mathematical knowledge is of the first order – and it is true eminently, in other words, at the same time, as better possible knowledge and as knowledge revealing, best, through its own incompletion, the incompletion of any accessible knowledge (whose it is constitutive or auxiliary). Of the second order, is the eidetic knowledge (knowledge of the Forms – eidê, ideai – otherwise called Ideas), which is the knowledge of the really real (ontôs on) (whose the object, in its grasp, can only sign the real reality of the knowledge itself). From her part, the mathematical knowledge leads, in its incompletion, the knowledge of its principle and element, that is the real unit (that is unique, inseparable and undifferentiated, and thus paradoxically unknowable, in what, it leads, itself, the order of the real knowledge, that is the eidetic order), unit supposed to find, in the geometrical order, its expression, as measure and element common to all the measurable (the extent) and, at the same time, to all the countable ; expression which does not miss to be problematic (aporetic), the size remaining, theoretically, indefinite, and any size being divisible in the infinity, in smaller sizes. So, is attested the fact that the present (ordinary) cognitive disposition is inevitably to be disposition to the real knowledge, in the fact that this one should be in particular knowledge of the principle, the principle which we think of finding indicated, at Plato, under the expression “principle of the line”, dynamic and active, specifically not mathematical principle, always previous to any determination (size) – and, at the same time, to any enumeration – whatsoever

Texto completoA high frequency of deaths due to ill-defined causes and incomplete diagnoses compromise the validity of cause specific mortality indicators, constituting an obstacle to the rational allocation of health resources based on epidemiological profile. This study evaluates the quality of information regarding the underlying cause of death in the Médio Paraíba region, state of Rio de Janeiro, Brazil, in the years 2005 to 2009 for the entire population. Data were obtained from the Mortality Information System (SIM) provided by DATASUS / MS. The analysis was based on two indicators of proportional mortality, the proportion of deaths due to ill-defined causes (IDC - Chapter XVIII, ICD-10) and incomplete diagnosis (ID) according to the classification presented in the Burden of Disease Project in Brazil, 2002. The association between quality of information of the underlying cause of death and demographic, socioeconomic and related to the occurrence of deaths covariates was assessed by calculating odds ratios of deaths due to IDC and ID in relation to the remaining causes of death. Proportional mortality due to IDC in the Médio Paraíba was found to be 4.54% in the period 2005-2009, values similar to those expected in developed countries. However, following a national trend, the proportion of incomplete diagnosis in the Médio Paraíba region, in the same period was high (20.59%). Together, the proportions of deaths from IDC and ID in the Médio Paraíba region in the quinquenium from 2005 to 2009, reached 25.13%, above the median value of 12% estimated for the world population. The odds of deaths due to IDC and ID decreased at higher levels of education. As for the variable race, the deaths of the black subjects had higher odds of having IDC. Deaths of white individuals were more likely to be listed as the underlying cause ID. Among deaths without medical assistance chances of IDC and ID were higher in relation to deaths with assistance. The deaths in hospital had lower odds of IDC and greater chances of ID. The variables had ignored or not reported were associated with higher odds of IDC and ID. The results suggest that in the Médio Paraíba quality of mortality data regarding IDC is well above the national level, resembling the values of developed countries. Still, the proportion of residual causes is quite high, showing that despite the significant improvement of SIM persist limitations that restrict the wider use of the system and prevent that advances policies and programs in health are greater.

Texto completoStarter cultures confer enhanced properties to improve organoleptic, sensory and nutritional attributes upon the cheese matrix. The subject of this PhD project was the patented Bionatif® process. That process purifies raw milk from hygiene and spoilage microflora. Then, it restores a functional Undefined Mixed Starter Culture (UMSC) to the cheesemaker. That unique UMSC is composed of an intra-specific bacterial diversity specific to the terroir where the raw milk is collected.This work fixed two goals: i) to characterize the diversity of the UMSC and study their metabolic potential, ii) to study the expression of the UMSC in soft cheese technology. The UMSC intra-specific diversity study highlighted some bacterial variants of the L. lactis species. UMSC's L. lactis isolates showed superior and diversified metabolic properties through the expression of their sugar metabolism (D-xylose, D-tagatose, etc.). A comparative genome study confirmed this result and could link these metabolic properties to an environmental origin. L. lactis isolates also possess rich CRISPR-Cas clusters. These clusters could confer them a high resistance against bacteriophages. Besides, an antimicrobial potential has been phenotypically observed and then confirmed through genomic studies. In soft cheese technology, the comparison between defined starter cultures designed under laboratory conditions and UMSC from the Bionatif® process demonstrated that the more complex and diversified the bacterial consortium of the UMSC, the better the sensory and rheological properties of the cheese

The creation takes place and continues on within this constant change in perspectives.

Lü Liuliang was an important scholar during the Ming-Qing transition. His reputation is not only illustrious, but also known to posterity. A great part of the reason why Lü Liuliang is known to people is the “involvement” of the Zeng Jing case happened in Yongzheng Emperor. From then on, Lü Liuliang, who has been dead for more than fifty years, becomes the main target of Qing Government’s attack, a special example of rebellion against Qing Dynasty, and a model of lots of cases. Being a Ming loyalist in Qing Dynasty, Lü Liuliang, as we learn from the past, was appraised according to his political intention. A stereotype image of Lü Liuliang has been built since nobody doubts who he is or what he has done. However, the way of looking at Lü in the past needs some amendment by examining Lü’s theories and appearances. It is easy to find from Lü’s academic works that he does not hold anti-Qing will as people are convinced. On the contrary, a lot of Lü’s politics ideas are just the same as those of the Qing government. The spread of the wrong image of Lü has been created since the anti-Qing case broke out. The officials imposed the memories for over a century, after that, the revolted image of Lü was exactly established and lasted until the end of Qing Dynasty and the early Republic of China. Also, it was till then, people reaccepted and turned the image of Lü to a positive model, and used it to set up a hero and a pioneer of nation in anti-Qing. According to my research, Lü Liuliang has no intention or practice of anti-Qing all the way. Furthermore, his position, significance, and value on the Confucian school should not be ignored even though he repeatedly becomes a target attacked by the Qing government. For example, Lü strongly advocates that Cheng-Zhu School is the orthodox Confucian system and makes an all-out effort to refute the opinion that Wang School is evil. This opinion, as a discipline, is the criterion Lü uses to judge everything. He does play a great role in the development of Confucianism in the early Qing Dynasty. Besides, Lü shows his achievement and representation on his Cultural establishments. People praise that he can compose, collect, criticize, compile, engrave publications, sell publications, and so on. He also wins an excellent reputation for publication of the mass media. Because of Zeng Jing case, Lü Liuliang’s corpse is disinterred as his head is severed and exposed. Qing government leads the image of Lü Liuliang; from then on, people start to neglect and distort Lü’s achievements in academic thought and cultural businesss. By the records of texts and the change of time, we can not only find that the course of history of resistance to and acceptance of Lü Liuliang gets complicated, but also find the followed mark of the development of history.

Abstract Ideal rechtsstaat principles should act through strict and meticulous legislation process to direct and monitor administrative decisions, and they should assure that these acts are made in due process of law through post-hoc judicial reviews. Therefore, laws should be precisely and comprehensively enacted for administrative authorities to abide by. However, in this multi-value conflicting society, it is difficult for legislators to continue to accomplish its mission of righting the society by using the legal norms of conditional structure. Instead, they should positively award discretionary power and beurteilungsspielraum to the corresponding administrative authority, so that the latter will be capable to investigate the conflicts of interests on a case-by-case base. It is also commonly seen in many administrative acts that in addition to taking administrative actions on various cases while the administrative authorities carry out their duty by practicing the discretionary power awarded by law, based upon various considerations, the legislators also choose the variable ambiguous legal concept to cover the complicate social realities. In addition to the laws of legal norms, people also obtain their legal knowledge from many forms of administrative interpretation, conventions, customs, and criteria released by administrative authorities. By knowing these forms and how they are executed, people shall in accordance adjust their social life or personal behavior. In case the administrative authorities fail to protect the rights of people, the justice system should assert its reviewing function to preserve people's benefits. In order to maintain people’s health, Taiwan’s Medical Law delegates administrative responsibility to doctors. However, because of their highly trained professionalism, their medical actions are not to be completely governed by ordinary laws. Therefore, the ambiguous legal concept should be introduced into medical laws. However, a balance between respecting medical professionalism and protecting people’s health should be reached; while doctors are respectfully allowed to fully practice their professionalism, certain binding regulations and restrictions should be added along to ensure people's life and health. The administrative authorities enjoy a wide range of power in the applying the discretion and undefined legal concept in medical laws. The writer asserts that only by the concepts of equity and proportion, and by explicit legal norms and reasonable justice relief, would people's health and doctors’ professionalism be both maintained.
