computation time require for running task should be minimize. • Data skew (i.e Unbalancing load of reducer) can be avoided by using data sampling technique. • Use effective partitioning technique to minimize time complexity of algorithm. • Determine if there is any slow running node by comparing the performance of each node with other. • If there is any such node move the data that is processing on that node. Feasibility Assessment Decision Problem The class of polynomially solvable problems, P contains all sets in which membership may be decided by an algorithm whose running time is bounded by a polynomial. P is the class of all decision problems that are polynomially bounded. The implication is that a decision problem X \$ in\$ P can be solved in polynomial time on a deterministic computation model . Problems in class P can be solved with algorithms that run in polynomial time. If the running time is some polynomial function of the size of the input**, for instance if the algorithm runs in linear time or quadratic time or cubic time, then we say the algorithm runs in polynomial time and the problem it solves is in class P. If there is a fast solution to the search version of a problem then the problem is said to be Polynomial-time, or P for short. Example- In graph theory, the shortest path problem is the problem of finding a path between two vertices (or nodes) in a graph such that the sum of the weights of its constituent edges is minimized. The problem of finding the…

Q3. If the second clerk could be added anywhere you choose (and not necessarily to check for violations, as in Question 2), what is the maximum number of applications the process can handle? What is the new configuration? Approach: Analyzed the question, we added one more clerk in step 2 (process and record payment). Then use the formula as question 1 and 2 to calculate. Figure 3.1 Solution: When add the second clerk in step 2, then solve and record payments. We could see the above pictures, 2…

Judge, Jackson, Shaw, Scott, and Rich (2007) performed a meta-analysis, which explored the impact of self-efficacy on task- and work-related performance, while holding individual variables constant. Through performing a multivariate analysis of these data, they found that the impact of self-efficacy on work performance was affected by several variables. Judge et al. (2007) found that self-efficacy provided greater incremental validity, or value added, when the complexity of the relevant job or…

to find positivity in life, but leaves the sonnet in a negative tone for how complex it is to feel happy about life, when knowing it will end. While Byron uses night and bright in the beginning of the sonnet, Shelley uses it in the end. Shelley, like Byron, rhymes “bright” with “night”, but in a different context. Shelley tries to incorporate an ideal balance of serenity to life because even though life is so complex and hard to understand at times, you have to just live it, no matter how much…

My past experiences are so varied that even I get lost when considering my own identity, but, as I am thinking about writing a thesis and asking much more pointed questions and demanding concreteness. I have found the answer I keep coming to is, I want to make simple things, things that allow myself a reprieve from the complexities of my inner emotional, intellectual, and relational realities. I like that, as humans, we have been given a remarkably simple set of shapes, or functions that are the…

From the transition of the Neolithic era to the early agrarian era to the late agrarian era, populations increased, inventions continued to be created, and technologies advanced. Humans began to live an agricultural lifestyle which began in living in villages, villages became towns and towns became cities. The emergence of cities gave human history a new threshold of complexity. The textbook “Big History: Between Nothing and Everything” describes thresholds of complexity as a point where new and…

Similar to paper clips, they are simple in design, materials and manufacturing, and are a product that can be found in almost every household.) How are these related and why are they innovations? What makes them better than other products. Paley examines how reliability and simplicity are related in many ways. The simpler that your invention is, the more that it relies on natural properties and therefore the more robust it becomes. As inventors, we should always try to use natural properties to…

needs. It also allows students to look deeper into the book and discuss these findings in a scaffolded environment which is beneficial in more complex topics. In relation to the current student’s needs and ability I believe that the most appropriate lesson type is the guided reading format. The student has problems with cross-checking and linking MSV and although the shared reading format is beneficial with understanding a text and the ideas within that text it does not allow much time for the…

Brain Caswell explores the themes appearance and reality, showing how appearances can be deceptive and how humans are complex in his novel, Double Exposure. He does this by using the metaphor of double exposure, and characterisation. Caswell also effectively used intertextuality to ensure that the reader has a greater understanding of the main themes, and to convey different ideas that are explored during the novel. Double Exposure deals with ideas of how appearance and reality can be…

time. However, it took me nearly all of the rest of the summer to fully understand why the algorithm can yield better estimation when the sample data is sparse. After several iterations of presentations, I was finally able to clearly explain the proof given in the original paper and even found an improved proof in the end, largely thanks to my research advisor’s constantly pushing me to define variables in the most accurate terms, prove each step rigorously, and trace the author’s logic behind…
