The Learn the analysis of a Set-Reset Flip-flop with Deeds
No full textThe Set State
Consider the circuit shown above. If the input R is at logic level “0” (R = 0) and input S is at logic level “1” (S = 1), the NAND gate Y has at least one of its inputs at logic “0” therefore, its output Q must be at a logic level “1” (NAND Gate principles). Output Q is also fed back to input “A” and so both inputs to NAND gate X are at logic level “1”, and therefore its output Q must be at logic level “0”.
Again NAND gate principals. If the reset input R changes state, and goes HIGH to logic “1” with S remaining HIGH also at logic level “1”, NAND gate Y inputs are now R = “1” and B = “0”. Since one of its inputs is still at logic level “0” the output at Q still remains HIGH at logic level “1” and there is no change of state. Therefore, the flip-flop circuit is said to be “Latched” or “Set” with Q = “1” and Q = “0”.
Reset State
In this second stable state, Q is at logic level “0”, (not Q = “0”) its inverse output at Q is at logic level “1”, (Q = “1”), and is given by R = “1” and S = “0”.
As gate X has one of its inputs at logic “0” its output Q must equal logic level “1” (again NAND gate principles). Output Q is fed back to input “B”, so both inputs to NAND gate Y are at logic “1”, therefore, Q = “0”.
If the set input, S now changes state to logic “1” with input R remaining at logic “1”, output Q still remains LOW at logic level “0” and there is no change of state. Therefore, the flip-flop circuits “Reset” state has also been latched and we can define this “set/reset” action in the following truth table in Rajah 2

Aplikasi Web Sentimen Analisis Komentar Media Sosial
Get PDFNowadays more and more business actors, both large companies and retail are switching or developing business in the digital direction. In business, websites and social media usually only work for introducing and marketing products to consumers. Though many other things can be obtained through websites and social media are like patterns of consumer sentiment towards a product. Sentiment Analysis is a technique of extracting text data to obtain information about positive, neutral sentiment or negative. Sentiment analysis is an assessment or personal opinion posted by internet users on social media. But currently, there is no application that can carry out the process of analyzing social media sentiment as well as showing word cloud dynamically. This study aims to develop an application that is able to perform social media sentiment analysis with output in the form of a chart of the number of sentiments positive/negative/neutral and word cloud, where machine learning polarity is used as a classification method.Saat ini semakin banyak pelaku usaha, baik perusahaan besar maupun ritel, beralih atau mengembangkan usaha ke arah digital. Dalam bisnis, website dan media sosial biasanya hanya berfungsi untuk mengenalkan dan memasarkan produk kepada konsumen. Padahal banyak hal lain yang dapat diperoleh melalui website dan media sosial seperti pola sentimen konsumen terhadap suatu produk. Analisis Sentimen adalah suatu teknik mengekstrak data teks untuk mendapatkan informasi tentang sentimen bernilai positif, netral maupun negatif. Analisis sentimen diberikan oleh pengguna internet pada media sosial untuk memberikan suatu penilaian atau opini pribadi. Namun saat ini, belum ada aplikasi yang dapat melakukan proses analisis sentimen media sosial sekaligus menunjukan wordcloud secara dinamis. Penelitian ini bertujuan untuk mengembangkan aplikasi yang mampu melakukan analisis sentimen media sosial dengan output berupa diagram jumlah sentimen positif/negatif/netral dan wordcloudnya, dimana machine learning polarity digunakan sebagai metode klasifikasi

RISK MANAGEMENT METODS ANALYSIS FOR SOFTWARE DEVELOPMENT: A Systematic Literature Review
No full textOne of the main reasons for software project failure is the lack of risk management. To satisfy consumers in developing software, in the software development process there are risks that must be minimized. To manage risks in software development projects, researchers use several methods.In a software development project, there is a risk of project failure and threats that may arise in project implementation. Risk management has an important role during project implementation. The purpose of this paper is to conduct a literature review of several risk management methods such as Agile, Scrum, RM4Am, and Random Forest Algorithm in an effort to minimize the risks that arise and identify gaps and opportunities for further research
The Analysis of A JK-Flip-Flop With Deeds
Get PDFIn order to have an insight over the working of JK flip-flop, it has to be realized in terms of basic gates similar to that in Diagram 2 which expresses a positive-edge triggered JK flip-flop using AND gates and NOR gates. Here, it can be observed that the output Q and the clock pulse are logically anded using the AND gate 1, A1, whereas the output Q? is anded using the clock pulse and the input J. (using AND gate 2, A2). Further the output of A1 is fed as one of the inputs (X1) to the NOR gate 1, N1 whose other input (Y1) is connected to output Q?. Similarly NOR gate 2, N2 has its two inputs (X2 and Y2) as the output of A2 and output Q (respectively). Initially let J = K = 0, Q = 0 and Q? = 1. Now consider the appearance of positive-edge of the first clock pulse at the CLK pin of the flip-flop. This results in X1 = 0 and X2 = 0. Then the output of N1 will become 0 as X1 = 0 and Q? = 1; while the output of N2 will become 1 as X2 = 0 and Q = 0. Thus one gets Q = 0 and Q? = 1. However if one considers the initial states to be J = K = 0, Q = 1 and Q? = 0, then X1 = X2 = 0 which results in Q = 1 and Q? = 0. This indicates that the state of flip-flop outputs Q and Q? remains unchanged for the case of J = K = 0.
Now assume that J = 0, K = 1, Q = 0 and Q? = 1. Analyzing on the same grounds, one gets X1 = X2 = 0 which further results in Q = 0 (and hence Q? = 1). For the same case if Q and Q? were 1 and 0, respectively, then X1 = 1 and X2 = 0 which would result in Q = 0 (and hence Q? = 1).
This implies that if J = 0 and K = 1, then the flip-flop resets (Q = 0 and Q? = 1).Next if J = 1, K = 0, Q = 1 and Q? = 0, then X1 = X2 = 0 which results in Q = 1 (and thus Q? = 0). For the same case if Q = 0 and Q? = 1, then X1 = 0, X2 = 1 which leads to Q? = 0 and hence Q is forced to value 1. This means that for the case of J = 1 and K = 0, flip-flop output will always be set i.e. Q = 1 and Q? = 0.
Similarly for J = 1, K = 1, Q = 1 and Q? = 0 one gets X1 = 1, X2 = 0 and Q = 0 (and hence Q? = 1); and if Q changes to 0 and Q? to 1, then X1 = 0, X2 = 1 which forces Q? to 0 and hence Q to 1. This indicates that for J = K = 1, flip-flop outputs toggle meaning which Q changes from 0 to 1 or from 1 to 0, and these changes are reflected at the output pin Q? accordingly
