The cash card emphasizes is the fast nuclear card facilitates the loan to be allowed to borrow the loan immediately, therefore its verification procedure is more loose. Also the cash card verification basis majority of all is extends with the credit card service pattern written credit comments the chronometer, this to the loan latent credit risk appraisal effect and the ability is very limited.Therefore, how completes the credit risk the appraisal, correct distinguishes the loan risk degree, this for this research center of gravity. But this research mainly emphatically analyzes in monopolizes with under the market mechanism which completely competes, how does the bank subscribe decides the most suitable cash card to lend money the contract to avoid the counter choice question the production, causes to be supposed to lend money the contract to be able to satisfy the bilateral biggest expectation benefit. When market mechanism for monopolizes, the bank cannot use collaterals to come the loan which the area weight plants the different type. If in perfect information, low risk type loan payment interest rate and handling charge higher risk for high, also this time bank cannot to be high, the low risk loan implementation credit ration. If in asymmetry information, can have two kind of possibilities the conclusions: First kind with to perfect information situation, but silver guild to high risk loan implementation credit ration; The second kind pays the same interest rate and the handling charge for all loans, but the bank cannot to the loan implementation credit ration. When the market mechanism for completely competes also the perfect information, the bank does not request the loan to provide collaterals, also cannot to its implementation credit ration, but the low risk loan pays interest rate and the handling charge higher risk loan comes low. If when asymmetry information, the bank can request the low risk type the loan proposes collaterals, the use collaterals differentiates the loan type, this time the loan which lends money the agreement to be allowed to differentiate the different risk degree, is a separation is balanced (Separating Equilibrium).

The purpose of the study is to contribute with knowledge of children´s exploration and conversing during an experiment consisting of mixing and separating. The study was conducted on the basis of an inductive and qualitative approach where semi-structured interviews were used as a method. A socio-cultural perspective was used as it is the children´s exploration and conversing about a scientific content that is in focus. The collected data was analyzed with inspiration from a phenomenographic analysis model. The result shows that the children asked questions and made descriptions regarding the content of the experiment, but there were also questions that were not about the scientific content of the activity. The children compared the different processes mixing and separating with more everyday events and their conceptual use increased during the course of the experiment and this after they had been introduced to them. The conclusions show that the active role of the interviewer was crucial for the visibility of the scientific content of the activity.

The purpose of this study was to determine if size exclusion chromatography could be used to separate casein micelles from whey proteins for a rapid, direct test to measure percent casein in milk. A size exclusion chromatography column was developed for the separation having dimensions 100 by .4 cm. Packing material selected was glycophase coated porous glass supports. A Beckman DU-8B spectrophotometer monitored the casein and whey protein peaks as they eluted and a Tektronix 4052 computer accepted data points every 4 sec, storing these on tape. Absorbances and areas of each peak were used in the evaluation of samples. Treatments of temperature, pH and calcium addition were performed on a commingled milk sample from Utah State University Dairy Laboratory. It was determined that addition of calcium and pre-warming to 40 C before injection is important for good separation. Several samples of milk from individual cows were run through the column and parameters obtained. For each sample, percent casein was measured using the standard method of acid precipitation and Kjeldahl nitrogen determination. Percent casein was then estimated using area and absorbance of each casein peak from the elution plots of milk from individual cows. A regression line of predicted vs actual percent casein resulted in a correlation coefficient (r) of .92.

Background. Neural Networks have mainly been used in behavior and gameplayrelated areas in games, but they have not yet been used specifically for intersection testing. This thesis explores the possibility to use deep neural networks for intersection testing of two 3D meshes. Objectives. The main goal of the thesis is to train a Deep Neural Network that can be used to replace traditional intersection test algorithms by having similar accuracy and a faster execution time. Methods. The research methods used in this thesis are implementation and experimentation. The deep neural network is trained using TensorFlow. Two different mesh generation techniques are implemented, one generating heightmaps and one generating planets. The two mesh types are combined to test all combinations of generated meshes. Attempts to make the network as general as possible are done through importance sampling to expose the network to tricky situations. A test application is developed where the intersection testing can be performed and compared to the Separating Axis Theorem (SAT). Heatmaps are also created to see how accurate the network is. Results. The results show that the network is accurate at classifying intersection between meshes similar to the ones it trained on. However, the network lacks generality and has bad accuracy if new meshes are introduced. The measured execution times show that the trained Deep Neural Network is 15.6 times as fast as a singlethreaded implementation of the SAT and 2.3 times as fast as the multi-threaded SAT. Conclusions. The trained network can be used as an early exit intersection test before using more expensive algorithms. The faster intersection testing can be useful in game physics by allowing faster classification of which meshes need to be tested for collisions. However, the main outcome is the shown potential for future work in the area including training a more general network, allowing variable mesh sizes, and providing information for solving collision responses. / Bakgrund. Neurala Nätverk har främst använts för beteende- och spelmekanikrelaterade områden inom spel, men de har ännu inte använts för genomskärningstester. Det här examensarbetet utförskar möjligheten att använda djupinlärning för att utföra genomskärningstester mellan två tredimensionella spelobjekt. Syfte. Huvudmålet med det här examensarbetet är att träna ett djupinlärt neuralt nätverk som kan ersätta traditionella genomskärningstestalgoritmer genom likvärdig precision och snabbare exekveringstid. Metod. Forskningsmetoderna som användes under examensarbetet är implementation och experimentation. Det djupinlärda neurala nätverket tränas med TensorFlow. Två olika spelobjektsgenereringsmetoder implementeras, där den ena genererar heightmaps och den andra genererar planeter. De två objekttyperna kombineras så att alla kombinationer av spelobjekt kan testas. För att göra nätverket så generellt som möjligt används importance sampling som utsätter nätverket för svåra situationer. Ett testprogram utvecklas där genomskärningstester kan utföras och jämföras mot Separating Axis Theorem (SAT). Grafer av typen heatmaps skapas också för att visa hur hög precision nätverket har. Resultat. Resultaten visar att nätverket har hög precision vid klassificering av spelobjekt liknande de som den tidigare har tränat på. Nätverket har sämre precision när nya spelobjekt introduceras. De uppmätta exekveringstiderna visar att det neurala nätverket är 15.6 gånger så snabbt som singeltrådade implementationen av SAT och 2.3 gånger så snabbt som den flertrådade SAT-implementationen. Slutsatser. Det tränade nätverket kan användas som ett tidig avbrott innan en dyrare algoritm används. Den snabbare genomskärningstestningen kan vara användbar i spelfysik eftersom den tillåter snabbare klassificering av vilka spelobjekt som behöver testas för kollision. Det huvudsakliga utfallet är den visade potentialen för vidare forskning inom området vilket inkluderar träning av ett mer generellt nätverk, möjlighet att variera spelobjektens storlek samt ge information för att kunna lösa kollisioner.

The thesis examines two related combinatorial objects, namely fingerprinting codes and separating hash families. Fingerprinting codes are combinatorial objects that have been studied for more than 15 years due to their applications in digital data copyright protection and their combinatorial interest. Four well-known types of fingerprinting codes are studied in this thesis; traceability, identifiable parent property, secure frameproof and frameproof. Each type of code is named after the security properties it guarantees. However, the power of these four types of fingerprinting codes is limited by a certain condition. The first known attempt to go beyond that came out in the concept of two-level traceability codes, introduced by Anthapadmanabhan and Barg (2009). This thesis extends their work to the other three types of fingerprinting codes, so in this thesis four types of two-level fingerprinting codes are defined. In addition, the relationships between the different types of codes are studied. We propose some first explicit non-trivial con- structions for two-level fingerprinting codes and provide some bounds on the size of these codes. Separating hash families were introduced by Stinson, van Trung, and Wei as a tool for creating an explicit construction for frameproof codes in 1998. In this thesis, we state a new definition of separating hash families, and mainly focus on improving previously known bounds for separating hash families in some special cases that related to fingerprinting codes. We improve upper bounds on the size of frameproof and secure frameproof codes under the language of separating hash families.

Present research has offered few easy-to-administer, accurate, and psychometrically-tested screening tools. Additionally, a gap exists in peer-reviewed literature concerning effective utilization of a family risk assessment instrument to determine the appropriate services for families involved in high-conflict custody cases. The purpose of this quantitative study was to determine if the Child Risk Index for Divorced or Separating families (CRI-DS) can be used as an effective family risk assessment tool to identify specific family needs and refer families to relevant court-related family triage services and programs. This study was grounded by Kellam and Van Horn's life course/social field theory. This study was supported by archival data. Correlation and regression analyses of 5 research questions addressing the relationships between family risk, court use, and related court services. Correlation results indicated both gender and marital status were significantly associated with an elevated pretest CRI-DS score and likewise conflict intensity also tended to increase. Study findings were consistent with previous findings that stress of divorce and separation was exacerbated by parental conflict and impacted the core relationships within the family; having long-term negative effects on the psychological well-being of the children involved. Using the CRI-DS as a triage instrument can facilitate the determination of which interventive services may be implemented for at-risk youth of high-conflict families, therefore promoting positive social change through the potential to improve the lives of at-risk youth and their families.
