Realization of equivalence class based clustering

The purpose of this thesis is to prototype an equivalence class based clustering algorithm and compare it against the current best algorithm for clustering, ECCC. The equivalence classes should be found using Grete Lind’s algorithm which is compared against the best algorithm in the same field, DPMiner, used by ECCC. The main problem addressed in the thesis is to find a faster and more effective equivalence class based clustering algorithm. In order to achieve that an analysis of DPMiner and ECCC along with a comparison of DPMiner and G. Lind’s algorithm is made. The result is a new equivalence class based clustering algorithm and its prototype. In addition to that, the thesis shows that even though the algorithm proposed by G. Lind is two times slower than DPMiner, the clusters created with its equivalence classes are 25% more accurate than the clusters created using DPMiner’s equivalence classes because DPMiner finds only discriminative equivalence classes. Additionally, the thesis shows that if each row contains the same number of attributes, which G. Lind’s algorithm assumes and DPMiner not, it is possible to gain a 10 time increase in average clustering speed.

IN NATIVE / NON-NATIVE INTERACTION

An echo answer is an answer that repeats elements of the question. This response form occurs after yes/noquestions and “statements about B-events”. The current study is based on data from native/non-native institutional interaction, and echo answers are shown to play an important role in certain types of repair that are characteristic of such interaction. Echo answers have two main usages. The first is to appropriate a candidate formulation and integrate it into one’s own turn in progress. This often happens when native speakers attempt to assist non-native interlocutors in expressing themselves. The other is to claim a strengthened commitment to the answer. This is especially salient in cases where a minimal agreement might project a potential dispreferred response. Echo answers may occur alone or with an initial or final response word, and these different response formats are shown to index the relative epistemic authority of the interlocutors.
Blogging about sexual assault Blogging about sexual assault : A thematic analysis

Purpose This paper examines the role of blogging (writing online weblogs) in facilitating healing following sexual assault. Design/methodology/approach To explore how blog writing may facilitate healing and recovery, thirty blog posts written by survivors of sexual assault were analysed using thematic analysis. Findings The analysis revealed three themes; the aftermath of abuse, the need for support, and helping others. In accordance with past research, bloggers frequently did not receive the supportive reaction to a face-to-face disclosure that they desired. Instead, blogging provided a safe environment in which victims could deal with the ongoing challenge of coping with, and recovering from the abuse. Moreover, blogging enabled victims to use their negative experience to educate and support others going through a similar experience, therefore allowing the bloggers to achieve some positive growth. Practical implications The results suggest that blogging and reading blogs may be beneficial to victims of sexual assault. Therefore, the findings support the recommendation of blogging by professionals working with victims of sexual assault. Originality/value The study presents the first analysis of blogs written by victims of sexual assault to facilitate their healing.

Corporate Incubators and Accelerators: A Qualitative Investigation into Their Deployment as Tools of Open Innovation

Established companies face high pressure to innovate along with high organizational inertia and resistance to change. Therefore, they increasingly establish and use corp orate incubators and accelerators to reach out to startups as external sources of knowledge and innovation partners. While the phenomenon of corporate incubators and accelerators has gained considerabl e traction in practice over the last years, it has done much less so in research. W e address this dearth of literature and contribute to this emergent field of research with early theory development based on a multiple -case study. We identify and explain the predominant innovation strategic orientation as well as the core processes taking place in the context of corporate incubation and demonstrate how they can help large and established companies t o become more innovative.
Carotid intima-media thickness and oxidative stress markers for assessment of atherosclerosis in children with b thalassemia major

The present study evaluates carotid intimamedia thickness (CIMT) in children with b thalassemia major to assess atherosclerosis and its relation to the underlying proposed causative mechanisms via lipid peroxidation product malondialdehyde (MDA), oxidized lowdensity lipoproteins (LDL), total antioxidant level, and lipid profile. A cross sectional study was conducted on 62 children (31 cases and 31 controls). CIMT by high resolution ultrasound and biochemical parameters i.e., total cholesterol, triglycerides, high-density lipoproteins, LDL, Oxidized LDL, lipoprotein (a), lipid peroxidation product MDA and total antioxidant were measured in enrolled subjects and compared. In our study, CIMT was significantly increased in b thalassemia major patients’ as compared to healthy controls. Mean CIMT in cases was 0.69±0.11 mm and in controls 0.51±0.07 mm. Mean oxidized LDL (EU/mL) in cases 39.3±34.4 (range 14.4 to 160) was significantly raised (P=0.02, t test) as compared to controls 23.9±13.4 (range 12 to 70). In our study we found MDA levels (nmol/mL) to be increased in b thalassemia patients as compared to controls. Mean MDA was 10.0±3.27 (4.41 to 17.48) in cases while in controls was 6.87±4.55 (1.5 to 17.9). Our study results show CIMT as an early marker of atherogenesis in b thalassemia major. Oxidative stress markers are also increased in b thalassemia major patients and lipoprotein (a) shows a positive correlation with CIMT. The present study points towards various atherogenetic mechanisms in b thalassemia major.
Tuning of Nonlinear PID Controller for TRMS Using Evolutionary Computation Methods

: In this paper, the Twin rotor MIMO system (TRMS) is tuned by Nonlinear PID controller using Evolutionary Computation methods. The proposed Nonlinear PID controller, used to tune TRMS, improves the system performance with additional degrees of freedom. Evolutionary Computation methods such as Differential Search Algorithm (DSA), real coded Genetic Algorithm (RGA) with simulated binary crossover (SBX) and Particle Swarm optimization (PSO) and Gravitational Search Algorithm (GSA) are used to determine the optimal parameters of the proposed controller by minimizing Integral Square Error (ISE) for rotor response of TRMS. SIMULINK MATLAB software is used for simulating the system. The statistical performance of the controller is analysed among twenty independent trials by taking best, worst, mean and standard deviations of ISE. Simulation results reveal that TRMS system tuned by nonlinear PID controller using Particle Swarm optimization (PSO) is better than the other methods
THE EFFECTS OF THINNING INTENSITY ON THE GROWTH OF ORIENTAL BEECH (Fagus orientalis LIPSKY) PLANTATIONS IN TRABZON, NE TURKEY

In this study, the effects of first thinnings having different intensities in oriental beech (Fagus orientalis Lipsky) plantation areas were investigated in terms of diameter and height growth of trees. Sample plots were chosen from oriental beech plantation areas which are within the boundaries of Maçka–Yeşiltepe and Vakfıkebir districts of Trabzon province, Turkey. With removing of 0%, 10%, 25% and 40% of basal area in a hectare of stands which are in sapling stage, sample plots were established by applying thinnings which are in four different intensities (control, light, moderate, strong). After the thinning applications, basal areas were calculated by measuring diameters and heights of trees in established sample plots in order to reveal stand growth. The effects of thinnings were revealed related to some stand characteristics (average diameter, basal area, average height, relative diameter increment, etc.) and determined chosen trees. The effect of thinning intensity on average diameter, basal area, and volume values is statistically important in every two plantations. 2-year results showed that thinning increased the diameter increment significantly, and the increase in diameter increment was positively correlated with the thinning intensity in both experiments. Moreover, increments of diameter, height, basal area, and volume were higher in Maçka-Yeşiltepe experiment than in Vakfıkebir experiment. But, the values of moderate and strong thinning intensities applied in Vakfıkebir were close to each other. When all the results are evaluated, application of strong thinning intensity for Yeşiltepe sample plot, the moderate thinning intensity for Vakfıkebir sample plot is seen appropriate by us in terms of both stand development.

SHIFTS USING A CACHE MEMORY

The use of cache memories and symmetric Kullback-Leibler distances is proposed for topic classification and topic-shift detection. Experiments with a large corpus of articles from the French newspaper "Le Monde show tangible advantages when different models are combined with a suitable strategy. Experimental results show that different strategies for topic shift detection have to be used depending on whether high recall or high precision are sought. Furthermore, methods based on topic independent distributions provide complementary candidates with respect to the use of topicdependent distributions leading to an increase in recall with a minor loss in precision.
Assessing the role of habitat and species interactions in the population decline and detection bias of Neotropical leaf litter frogs in and around La Selva Biological Station, Costa Rica

Worldwide, amphibian populations have been declining rapidly. This decline can be attributed to many factors including climate change, pesticide exposure, and emerging infectious diseases, among other important factors, but few studies have examined the influence of species interactions. In this study, we examined how habitat factors and co-occurring avian and mammalian species, as well as humans, exert direct and indirect effects on Neotropical amphibian population dynamics. We further examined how these habitat and species interactions could affect our ability to reliably detect amphibian presence to robustly estimate population trends. We conducted amphibian visual encounter surveys at 26 randomly selected sites in the La Selva Biological Station, in northeastern Costa Rica, as well as 26 sites across five additional forest fragments in the region. Furthermore, we used camera traps to collect data on avian and mammalian communities and human visitation at those amphibian survey plots. From these data, we were able to estimate species occupancy probabilities for leaf litter frogs across sites and their relationships to habitat and interspecific species interaction covariates. We also conducted an experiment with plastic model frogs to estimate detection probabilities when a population is known to occur at a site with certainty. Our results suggested that strawberry poison dart frog (Oophagapumilio) occupancy was positively related to secondary forest and their detection was negatively related to increasing air temperatures at the times of the surveys. Leaf litter frog occupancy was negatively related to core La Selva sites and human detections at sites, yet their detection was positively related to human trail presence, which might be related to reduced leaf litter cover due to heavy trampling. Our experimental surveys suggested that Neotropical leaf litter frog communities are difficult to detect when present and future studies should explicitly account for this detection bias to effectively monitor population trends.
BIG DATA WITHIN INNOVATION PROCESSES

Essay/Thesis: Master’s Degree Thesis / 30 ECTS Program: MSc Innovation& Industrial Management Level: Second Cycle Semester/year: Spring/2018 Supervisors: Prof. Johan Brink & Prof. Richard Tee Keyword: Big data, big data analytics, market orientation, innovation processes, pre-development activities, innovative productivity Background: The importance of innovation simply continues to stagger. Albeit, many firms continue to struggle in the launch of new technologies that meet the objectives of successful innovation. As a result, the life cycles of innovations are shortened and inadequate returns endure. Current research suggests modern technologies of big data can facilitate businesses as they strive to generate value-generating innovations. However, few explain what firms actually aim to find and how the extracted information supports activities within innovation. Purpose: The purpose of this study is to investigate firms’ usage of big data to facilitate market orientation related to the innovative process, while assess the impact such efforts have on firms’ innovative output. Theory: Shaping the research are the fields of: proactiveand responsive market orientation (Narver & Slater, 1990), pre-development theory inspired by the stage-gate framework and innovative productivity, as described by Kim and Mauborgne (2004). The latter enacts the comparative measure of innovative performance within this report, since it represents both the speed of innovative processes whilst simultaneously represents value-generating output of innovation. Method: This study is conducted through a deductive approach to research. Four hypotheses were constructed for testing against the gathered findings. With a cross-sectional design, an online questionnaire was distributed via LinkedIn to the Fortune 200 Global Companies of 2017 to collect quantifiable data. To test the hypotheses five main concepts were constructed on the basis of previous theory and the operationalization within adjacent research. Result: Given the four originally stated hypotheses due for assessment, three were accepted. Consequently, the findings suggest: (1) big data adoption; big data analysis within proactive market-oriented activities; and big data derived customer insight used within pre-development activities all demonstrate positive and significant correlations with innovative productivity. (2) The studied population preferably pursues market-oriented activities to extract and assess the latent needs of customers vis-à-vis expressed needs.
- 0101 Vibration Phase Measurements using Holographic Optical Elements

The application of an out-of-plane sensitive electronic speckle pattern interferometer (ESPI) using holographic optical element (HOE) to vibration amplitude and phase mapping is reported. The novelty of the proposed system is the use of a speckle reference wave stored in a reflection holographic optical element (HOE). The incorporation of a HOE minimizes the alignment difficulties. The HOE based ESPI system is compact containing only a diode laser, HOE and a digital CMOS camera. The measurement technique is a combination of time averaged ESPI and reference beam phase modulation in an unbalanced interferometer. The reference beam phase modulation is implemented by modulating the drive current of the diode laser. The presented HOE based ESPI system is easy to align and compact and thus suitable for industrial non-destructive testing and vibration analysis.
Federal Reserve Bank of Minneapolis Research Department Staa Report # 236 Capital-skill Complementarity and Inequality: a Macroeconomic Analysis

There have been striking postwar changes in the supply and price of skilled labor relative to unskilled labor. The relative quantity of skilled labor has increased substantially, and the skill premium, which is the wage of skilled labor relative to unskilled labor, has grown signiicantly since 1980. Many studies have found that it is diicult to account for the increase in the skill premium on the basis of observable variables and have concluded that latent \skill-biased technological change" is the main factor responsible for the increase. This paper develops a framework that provides a simple, explicit economic mechanism for understanding skill-biased technological change in terms of observable variables and uses the framework to evaluate the fraction of variation in the skill premium that can be accounted for by changes in observed factor quantities. We use a version of the neoclassical growth model in which the key feature of the aggregate technology is capital-skill complementarity, which means that the elasticity of substitution between capital equipment and unskilled labor is higher than that between equipment and skilled labor. We nd that with capital-skill complementarity, changes in observed inputs alone can account for nearly all of the variation in the skill premium over the last 30 years. Our ndings suggest that increased wage inequality is a consequence of economic growth driven by the introduction of new, eecient technologies that are embodied in capital equipment.

Platelet-rich Fibrin in Sinus Lift Procedures : A Systematic Review

DOI: 10.21276/sjodr.2018. 3.1. 2 Abstract: The aim of this review was to evaluate literature on the efficacy of platelet-rich fibrin (PRF) as a sole grafting material in sinus floor augmentation. The main advantage of PRF is the avoidance of a second surgical site needed for the harvest of autologous bone. A PubMed search was carried out, limited to human studies for articles on PRF as a sole grafting material. 15 unique results were found. Out of 15, 5 results met our inclusion criteria. All the studies were non-comparative and were analyzed for sample size, case-selection criteria, surgical technique, evaluation criteria, success rates and follow-up period. PRF showed promising results as a grafting material and is a relevant biomaterial for natural bone regeneration. Further, clinical studies including control groups in the form of randomized controlled clinical trials are required to establish the efficiency of PRF as a grafting material in sinus lift procedures.
Experimental Study the Effect of Tool Design on the Mechanical Properties of Bobbin Friction Stir Welded 6061-T 6 Aluminum Alloy

Bobbin friction stir welding (BFSW) is a variant of the conventional friction stir welding (CFSW); it can weld the upper and lower surface of the work-piece in the same pass. This technique involves the bonding of materials without melting. In this work, the influence of tool design on the mechanical properties of welding joints of 6061-T6 aluminum alloy with 6.25 mm thickness produced by FSW bobbin tools was investigated and the best bobbin tool design was determined. Five different probe shapes (threaded straight cylindrical, straight cylindrical with 3 flat surfaces, straight cylindrical with 4 flat surfaces, threaded straight cylindrical with 3 flat surface and threaded straight cylindrical with 4 flat surfaces) with various dimensions of the tool (shoulders and pin) were used to create the welding joints. The direction of the welding process was perpendicular to the rolling direction for aluminum plates. Tensile and bending tests were performed to select the right design of the bobbin tools, which gave superior mechanical properties of the welded zone. The tool of straight cylindrical with four flats, 8 mm probe and 24 mm shoulders diameter gave better tensile strength (193 MPa), elongation (6.1%), bending force (5.7 KN), and welding efficiency (65.4%) according to tensile strength.

It aims to provoke conversations about the limitations of mini-publics in promoting democratic renewal and reconsider the functions of these forums in democracy’s ‘dark times. ’
HARVEST DATES , CLIMATE , AND VITICULTURAL REGION ZONING IN GREECE

Climate is clearly one of the most important factors in the success of all agricultural systems, influencing whether a crop is suitable to a given region, largely controlling crop production and quality, and ultimately driving economic sustainability. Today many assessments of a region’s climate comes from a combination of station and spatial climate data analyses that facilitate the evaluation of the general suitability for viticulture and potential wine styles, allows for comparisons between wine regions, and offers growers a measure of assessing appropriate cultivars and sites. This research combines a spatial climate analysis in Greece with a temporal station and harvest date analysis in important Greek wine regions. The results show predominately warm to hot climate suitability in Greece, comparable to many other regions worldwide. While many viticulture regions have one primary class of suitability, variability of climate within regions can be significant, with some regions containing two to four climate classes, typically based on elevation or distance to the coast, making them suitable for a greater range of cultivars. For the temporal analysis the eight locations studied had marked differences in their general climatic characteristics, mainly between mainland and island areas. While trends varied for the regions, the general response was for greater increases in minimum temperatures compared to maximum temperatures, which resulted in significant trends in growing degree-days in most locations. Harvest dates trended earlier in five out of the eight regions, and were mainly driven by changes in minimum temperatures. Significant trends in climate parameters and viticulture–climate relationships were more evident for island regions when compared to mainland locations. Moreover, areas with late ripening varieties were shown to be less sensitive to climate changes.
