Abstract

Signatures are personal identities that can be used as evidence of document legality. The use of signs is fairly easy and simple, no expensive electronic equipmentneeded. This is what makes this signature is still common nowdays. The higher needs for transactions in society will give effects to the irresponsible parties. The lack ofsecurity tools for transactions or transactions involving this signature makes the roles of signature is at risk. The Signatures belongs to the authentic holder is supposed to be an important discussion for the sake of society.This research will discuss about signature identification to recognize the authentic holder of the signature. This process consists of two main parts: training and testing.The image size is 256x256 pixels. At the training stage, hand drawings used are the threshold, wavelet Symlet and Coiflet wavelets, normalization and then will begenerated using Backpropagation Neural Network (ANN) algorithm. The testing stage has the same process but at the end of the process will be comparison between theimage data that has been stored with the comparison image. ANN can work optimally when it is trained using the calculated data input, parameters, and number of nodes on the network. It is expected that these wavelets can determine the optimal wavelets and parameters in identification. The range of applied wavelets are Symlet and Coiflet.

Abstract

Psychological factors in patients with chronic renal failure conditions are severely affected by prolonged course of the disease, disability and discomfort should depend onthe hemodialysis machine. Hemodialysis therapy in addition to disturbing the physical, complications can trigger mental disorders. Patients with chronic renal failure often have psychological disorders associated with general medical conditions. Anxiety and depression are often psychological disorders experienced. Symptoms that are almost similar to each other will require experts to correctly identify them based on the patient's perceived symptoms. Limitations of health practitioners in exploring thepsychological conditions felt by the patient to be one reason for the necessity of a clinical decision support system capable of integrating patient information (demographic, clinical, social psychological) with a knowledge base with the aim of identifying psychological conditions in a clinical setting that can assist physicians, nurses, psychologists and health practitioners others in making a clinical decision on their patients. The approach in this study uses case-based reasoning (Case-Based Reasoning) (CBR). CBR process through four stages of the process are: retrieve, reuse, revise and retain. If there is a similar case then the reasoning to weigh the nearest case using the Simple Matching Coefficient (SMC) method so that the system is able to streamline the diagnostic process by taking into account the closeness between the base case and the target case. As a result, the system will be able to provide a recommendation picture of the initial diagnosis of the highest percentage of possible types of psychological disturbance suffered with its severity level and the best solution for new cases based on the nearest case solution of the nearest similarity level.
