Abstract:

With today’s focus on Continuous Integration, test cases are used to ensure the software’s reliability when integrating and developing code. Test cases that behave in an undeterministic manner are known as flaky tests, which threatens the software’s reliability. Because of flaky test’s undeterministic nature, they can be troublesome to detect and correct. This is causing companies to spend great amount of resources on flaky tests since they can reduce the quality of their products and services. The aim of this thesis was to develop a usable tool that can automatically detect flakiness in the R

Abstract:

Flaky tests are defined as tests that show non-deterministic outcomes, meaning they can show both passing and failing results without changes to the code. These tests cause a major problem in the software development process since it can be difficult to know if the cause of a failure originates from the production- or test code. Developers may choose to ignore failing tests known to be flaky when they might actually hide real bugs in the production code. This thesis investigates a specific category of flaky tests known as "Async Wait", which are tests that makes asynchronous calls to servers a

Abstract:

Background. Unstable and unpredictable tests, herein referred to as flaky tests, pose a serious challenge to systems in the production environment. If a device is not tested thoroughly, it will be sent back for retesting from the production centers, which is an expensive affair. Removing flaky tests involves detecting the flaky tests, finding the causes of flakiness and finally the elimination of flakiness. The existing literature provides information on causes and elimination techniques of flakiness for software systems. All of these are studied thoroughly, and support is taken from interview

Abstract:

A study has been made of the characteristics of flake brass powders, and a route has been developed to produce such powders by small scale vibratory batch milling. Brass flakes are used as pigments for producing a 'gold leaf' appearance in ink and paints, and there are a variety of other applications. The commercial production route involves the slow process of rotary ball milling a coarse feed powder on a continuous basis. Initially a range of industrially produced powders were examined by a variety of techniques to determine the relationship between powder characteristics and commercial qual

Questa dissertazione si concentra sul dibattito circa l’essenza della matematica a partire dalla nascita delle geometrie non euclidee. Essa è una scienza della natura o una costruzione (e dunque una libera invenzione) della mente umana? Trattando altresì della crisi dei fondamenti, e tenendo a mente le posizioni platoniste e costruttiviste, questa tesi analizza le risposte che, da fine Ottocento in poi, diedero Jules-Henri Poincaré, Bertrand Russell, L.E.J. Brouwer e David Hilbert, e con loro le varie correnti convenzionaliste, logiciste, intuizioniste e formaliste.

Graphite has high in-plane thermal conductivity and is a potential candidate to combat the thermal management problems in high density electronic devices. However, the properties of graphite are not fully exploited and this study was carried out with the aim of fabricating and analysing high thermally conducting graphite based composites. Model composites were prepared with three different average flake sizes: 180 μm, 300 μm and 600 μm. The constituents( flakes and binders) were characterised in terms of density, carbon yield and crystallographic perfection using combination of techniques. The

Abstract:

The key to improving drying quality and reducing drying time and energy consumption lies in understanding and controlling moisture movement during drying. As wood dries, strains and stresses develop as a result of restraints imposed by moisture gradients and differential shrinkage in wood. So accurately measuring the moisture gradient in wood during drying will be helpful to improving drying quality. <p> In this project, moisture gradients in red oak will be measured through four different techniques----<i><b>bandsaw slicing, Forstner bit layering, flaking and razor blade slicing</

The amount and morphology of the graphite phase largely controls the resulting properties of cast iron. For instance, in flake graphite cast irons the mechanical properties are low while the thermal conductivity is high. This is in contrast with spheroidal graphite cast irons where the mechanical properties are high and the thermal conductivity is low. These differences are due to the different graphite morphologies and must be accounted for in the design work and material selection of cast iron components.

Abstract:

Dans l'industrie microélectronique, l'augmentation constante de la densité de puissance due à la miniaturisation des composants électroniques nécessite un matériau de dissipation thermique ayant une conductivité thermique élevée (CT), un faible coefficient de dilatation thermique (CTE) et des propriétés mécaniques (PM) appropriées pour une dissipation efficace de la chaleur. Des métaux purs, tels que Al et Cu, ont déjà été utilisés. Cependant, ils ont des CT limitées (ex. 240 W/m.K pour Al) et leurs CTE sont trop élevés (ex. 23 10-6/K pour Al), ce qui est incompatible avec ceux des composants

Abstract:

In this thesis, the structural and mechanical changes, which took place in flake graphite cast iron after electron beam surface melting and chrome-nickel surface alloying, were studied. Furthermore, the effect of set parameters on properties and depth of the melted and alloyed region is also analyzed. In the experimental part, the analyzed microstructures, micro-hardness and the distribution of elements after melting and alloying, were presented. Structural differences of material regions caused by melting were described based on microstructures. In the end of diploma thesis, the conclusions o

Abstract:

This thesis work deals with the volume changes during the solidification of cast irons and peritectic steels. The volume changes in casting metals are related to the expansion and/or contraction of the molten metal during solidification. Often, different types of shrinkage, namely macro- and micro-shrinkage, affect the casting quality. In addition to that, exposure of the metal casting to higher contraction or expansion during the solidification might also be related to internal strain development in samples, which eventually leads to surface crack propagation in some types of steel alloys dur

Abstract:

This chapter reviews the literature examining interventions to reduce indoor tanning (IT). The first objective was to highlight programs that show promise for large scale dissemination. The second objective was to promote criteria and standards for future intervention research efforts. The scope of interest for this review includes universal (for everyone in the population), selective (for those in the population who are at a greater risk), and indicated (for those who already are experiencing conditions that identify them as at risk) programs. The evaluation of the interventions resulted in t

The mechanical properties of resulting graphite composite are not that good as expected, comparing with pure resin. To improve such situation, processing techniques, such as intercalation and exfoliation, are employed to make natural graphite turn into exfoliated graphite(EG). Exfoliated graphite is partly composed by graphite nanosheets, which are the additives of first graphite nanosheet in this work. Three types of composites were made to represent for three level
