5. Proposed Research Questions and Tasks
Four proposed research tasks will direct to fabrication conditions (Task 1), fabrication thermal analysis (Task 2), fabricated parts performance (Task 3), microstructure control methodology (Task 4), respectively. These tasks are designed to answer the questions and solve the problems in the results of preliminary experiments and observations from reported investigations.
5.1. Task 1. Investigating feasible formation conditions and effects of laser power and B content on ultrafine 3DQCN microstructure.
5.1.1. Research questions generation
In the TMCs manufacturing, fabrication energy and reinforcement content are two significant input variables [1,9,11], which are related to laser power and B content in laser deposition. Based on the preliminary results (Figure 6 in §4.5), laser deposition with low level of laser power could fabricate the 3D TMC parts, however, the 3DQCN microstructure was not found inside the parts. Low laser power led to poor fluidity of molten material, which would restrict movement of the in-situ reacted TiB whiskers. It also can be seen from Figure 6(a) that large-sized primary TiB was also formed at the low level of laser power, which would impede the formation of the 3DQCN microstructure. Meanwhile, 3DQCN microstructure would not be formed due to high fluidity of liquid material induced by very high laser power . In the preliminary experiments, the B content was 1.6 wt.% with the purpose of following…
Enthalpy of Dehydration of Sodium Acetate Trihydrate
In this lab, two solid substances, sodium acetate and sodium acetate trihydrate, will be analyzed for the heat of solution for both processes. This allowed the calculation of the molar enthalpy of dehydration of sodium acetate trihydrate. Calorimetry was used to experimentally determine the heat of solution for both reactions.
This lab was performed based on the procedure outlined in “Exp #7 Calorimetry.” No changes to…

Initial Differential Diagnoses
M.G. presented to the clinic today clean and intact. She is well developed, well nourished and in no apparent distress. I examined her face, neck area, bilateral hands, trunk and upper and lower back, and other parts of her body. She has diffuse eczematous lesions in various stages. Macular, popular, erythematous rashes were discovered on her extremities and trunk. Her…
The diffraction pattern was scanned over 2 range of 3 to 50o at a scanning rate of 1o/min. The relative degree of crystallinity (RDC) was calculated to determine the degree of drug crystallinity in formulation compared to pure drug, by using the following equation18. (Maulvi et al., 2011) EXM…
had to use transistors at some stage in this project. The project was successfully designed and built in two ways: one with solely using operational amplifiers and other using transistors as differential amplifiers.
Electrocardiography (ECG)/ Background
The heart is one of the vital organs in the human body. The heart behaves like a pump that circulates blood and oxygen around the body in order for the human body to function flawlessly. Waste products are removed from the body…
investors will not pay for risk premiums, and defined by following stochastic differential equations:
Where: S(t) represents the price process of an underlying assets. V(t) is the variance of the corresponding instantaneous returns. And the initial condition S(0), V(0) should be strictly positive. r is the risk-free return rate (non-negative constant). k is the speed of the mean reversion. θ is the mean value of the variance. σ is the volatility of the variance. These three are positive…
For example, consumer organizations are keener towards social factors, while political factors play a vital role in defense industry.
Environmental scanning can present numerous rewards for modern Health Service. It can contribute to an organizations renovation, one that constantly seeks new practises that could modify it’s place in the market. Furthermore environmental scanning assists in the improvement of planned procedure and policy. Therefore, developing an understanding of…
CONNECTIONS OF LOGARITHMIC FUNCTIONS
Logarithm and exponential functions have close relationship and they are inverse function of each other in a way. Before explicitly clarifying this inverse relationship, we should analyze their definitions. Logarithm means, in mathematics, “The exponent that indicates the power to which a base number is raised to produce a given number “2 Exponential function means that “mathematical function in which an…
Before we talk about measurement scales and why they matter we should first explain what they are. A compound measure allows us to measure different aspects of a topic people would find complex. This topic could range from stem cell research to abortion to gun control. The good thing about compound measures is they have a general reliability to them. What I mean is, if an error is made it often does not make the whole measurement go wrong.
Compound measures should have several different…
1. What are the least, and most, amount of distinct zeroes of a 7th degree polynomial, given that at least one root is a complex number?
If the equation is 7th degree then it has 7 roots.
Those roots can be complex or real.
Complex roots always come in pairs, so if it has one, then it has 2, the other one being the conjugate of the first one. This in other words, if one complex root is a + bi, then the other complex root is a – bi.
If at least one root were complex, then we would have a…
