Scientific Methods of Inquiry | GET EXPERT ANSWER

Write a 3 pages paper on scientific method of inquiry. Scientific Method of Inquiry Identification and of Scientific Methods of Research Enquiry and Their Application in a Research Project Methods of research enquiry are often considered as the ways wherein an individual can seek answers to specific research questions. There are numerous methods of research enquiry and one of the popular amid them is scientific method. Scientific method is regarded as a set of methods that are normally used for examining research phenomena, acquiring adequate research information and incorporating new knowledge. There are several scientific methods that can be executed for conducting an effective research inquiry (Michael, 2002). With this concern, the first method is rational method. This method includes seeking answers to a research questions through considering analytical perception. It involves arguments with respect to premises and assumption. It can be applied in a specific research through way of logic. Logic in this context can be of two types such as deductive logic and inductive logic. Deductive logic usually moves from general assumptions to particular locus. On the other hand, inductive logic makes generalizations based on observations. The second method of research enquiry is method of empiricism. This method uses observation and direct sensory experience in order to acquire valuable information (Rybarova, 2006). The third important scientific method is probability. It can be apparently observed that the researchers use this particular method while making inquiry to a specific research subject. In a research, probability method can be used by assuming the likely truth in accordance with best evidence. It is worth mentioning that the research and testing of a research question or a specific theory is based on the probability method. For example, if researchers desire to understand the reasons for shortages in supply of illegal drugs, the probability method can be based on the argument that the shortage is due to strong legal enforcement (Prunckun, 2010). The fourth vital scientific method of research inquiry is variables. In scientific method, variables can take in several unconditional forms such as items, activities, thoughts and moments among others. The variables can be applied in a research in the form of independent as well as dependent variables. The independent variable is sovereign in nature and is not impacted by other variables. It performs on dependent variables that are regarded as the basis of inquiry. For example, if researchers want to inquire the role of illegal drugs on criminal activity, then illegal drugs would be considered as an independent variable and criminal activity would be regarded as a dependent variable. The fifth important scientific method for research enquiry is hypothesis. It is an estimation which is subjected to information obtained. Hypothesis can be applied in a research through the creation of null and alternate hypothesis. For example, in understanding the role of illegal drugs on criminal activities, null hypothesis would be that illegal drugs have no relationship on conducting criminal activities. Conversely, alternate hypothesis would be that illegal drugs have positive relationship in performing criminal activities (Prunckun, 2010). Development of a Hypothesis In order to undertake a scientific method of enquiry focusing upon the professional practices of criminal justice practitioners, the following hypothesis has been developed. Null Hypothesis (H0): Airline regulation has not improved since 9/11 attack Alternate Hypothesis (H1): Airline regulation has improved since 9/11 attack Methods of Enquiries and Application In order to evaluate the above hypothesis, two inquiry methods can be used. The first method of inquiry is rational method. As described above, rational method tends to seek answers for a research question by taking into concern the logical perception. Thus, in order to evaluate the above hypothesis, a strong research question must be developed. In relation to the above hypothesis, the research question can be as follows: ?Does present airline regulations are effective to stop terrorism attacks?? It can be affirmed that the above framed research question would help in understanding the effectiveness of airline regulations in current day context and will also help to generate a logic to the research hypothesis. It is worth mentioning that the inquiry would follow inductive logic where generalizations would be made on the basis of personal observation. Apart from rational method, variables can also be used in order to inquire the research subject. For instance, relating to the above hypothesis, the independent variable would be aviation or airline regulations and the dependent variable would be terrorist attacks. In this context, it can be stated that the hypothesis can be measured through understanding whether the independent variable has generated certain changes or not in the dependent variable. Specially mentioning, every variable has certain attributes and specific values. These attributes are mutually exclusive in nature. Understanding affiliation between these attributes can help to analyze the hypothesis. There are several methods that can be used to analyze the hypothesis such as quantitative methods and qualitative methods. Utilizing these methods in testing of hypothesis through variables would help to reach into a concrete conclusion by a certain degree. References Michael, R. S. (2002). Inquiry & scientific method.

The Role of Temporary Works in Civil Engineering Construction | GET EXPERT ANSWER

Submit a 1500 words paper on the topic The role of temporary works in civil Engineering Construction. For example when setting up a scaffold it is advisable that your scaffold is supported by the ground but if that is not possible one can make it to hang above the ground or water using the hanging scaffold (Webster 1997). A good scaffold should also be able to have a safety mechanism in order to avoid injuries in case the scaffold fails thus in constructing a bridge one can chose to attach himself to the bridge to be safe incase the scaffold is failing. Formwork In his contribution Blackledge (1977) refers to formwork as the process that involves the addition of base material and also the addition of concrete that is in retaining wall so that they can be used as slabs during the construction of a bridge. Formwork is very essential since it helps to make the concrete last for long due to the fact that it makes it strong (Blackledge 1977). The strength property of formwork guarantees the much needed support that is needed in construction of the bridge. Formworks is used by making that needed shape using steel or aluminum so that the concrete is then poured into it so that a desired shape is produced. This is then allowed to harden. When it?s all dry the fabrications are removed and the formwork remains in place in that desired shape. Formwork is used to guarantees the strong support for the bridge during construction which always has to remain strong to avoid collapse (Blackledge 1977). Falsework In his book Webster (1997) talks of falsework as a term that is used to refer to the activity of supporting arches and spans in the process of constructing a bridge by using temporary support structures. This is a very essential practice in construction of bridges since it helps support the bridges from below in order to ensure that the bridges do not collapse as the construction is still continuing and can also be used to create a strong work base for the workers during the process of constructing a bridge. This always has to remain intact to the construction until that time when the bridge can self support itself without collapsing which in the long run helps to keep the bridge in position (Webster 1997). Temporary Support of Excavation During construction of a bridge it might involve excavating various sections of the work site so as to achieve a certain level of ease during the construction of bridge (Hummell 2011). For example during construction when the building is to start like two stories below the ground then excavation will have to be done in order to achieve this. Also good to notice is that sometime exaction is done for example when gravel is need for construction so that it is dug from a place. After excavation it?s a good practice to always support the excavations in order to avoid collapse of the walls during construction according to Hummell (2011). There are two types of excavation that can be used in supporting an excavation walls. this can either be flexible support or rigid excavation support. When one uses Flexible support then it would take sheet pilling, soldier pile and lagging walls. On the other hand rigid support entails slurry walls, secant piles or even tangent pile (Hummell 2011).

Alternating Current Theory in Use | GET EXPERT ANSWER

Write 6 pages thesis on the topic alternating current theory in use. Waveform represents a variation of current or a voltage plotted to a base time. The base line for alternating current waveform is the zero condition of voltage or current. The different types of AC waveform are given as, sine waveform, triangular waveform, square waveform, and the complex wave form as shown in the diagram below.When mixed frequency sine waves are produced, a series of sine waves is produced with the sine wave with the lowest frequency being the fundamental wave form while the others are called harmonics and there frequencies are usually whole numbers which are multiples of the fundamental sine wave.A cycle is the time AC waveform takes to move from a positive half-cycle to negative half-cycle and then back to zero and the time taken to complete a full cycle is referred to as periodic time.&nbsp.The amplitude of an AC waveform is usually represented as the maximum/peak value of voltage or current which the highest value reached by voltage or current during each half cycle.The average value of the square waveform usually equals the value peak voltage or current, which implies that the form factor of a square waveform is unit since the ratio of RMS value to the average value is one. This implies that square waves are equivalent to the summation of sine wave and an infinite series with frequencies of odd-multiples and have diminishing magnitudes as long as they are at the same frequency.

Material Engineering and the Production of X-rays | GET EXPERT ANSWER

Create a 5 pages page paper that discusses material engineering and the production of x-rays. The concept of X-rays was first discovered by a physicist from Germany called Wilhelm Roentgen in 1895. However, A.W. Goodspeed was the first person to make the X-ray discovery, on February 22, 1890. Because there was no information that could prove that he had discovered X-ray, Goodspeed named his discovery an accident and did not take any credit for the work he had done (Dyson 1). In the discovery, Wilhelm enclosed a glass tube inside of a black paper box. He attached wiring that ran inside the glass tube that resembled the inside of a light bulb. This enabled the electrical currents to build up in the glass tube. He then connected the tube to an induction coil apparatus that allowed an electric current to pass through the tube. This way, a faint green coloured light could be seen across the room. He decided to do this in a different way to be sure of what he had seen. He lit a match stick and discovered that there was a small screen in the room which was coated with a chemical. The lighting from the match stick sent the current along the tube. This made the exact same light to appear again. As he continued with his experiments, he discovered that these rays could penetrate through objects, such as wood and metal. Accidentally, his hand came in contact with the tube one day and saw shadows of his hand with darker shadows that represented the bones. When he moved his hand, the shadow on the screen also moved. He named the shadow the first x-ray picture (Lewin, Paradijs and Heuvel 373).
