Abstract

Heart disease is a notoriously dangerous disease which possibly causing the death. An electrocardiogram (ECG) is used for a diagnosis of the disease. It is often, however, a fault diagnosis by a doctor misleads to inappropriate treatment, which increases a risk of death. This present work implements k-nearest neighbor (K-NN) on ECG data to get a better interpretation which expected to help a decision making in the diagnosis. For experiment, we use an ECG data from MIT BIH and zoom in on classification of three classes; normal, myocardial infarction and others. We use a single decision threshold to evaluate the validity of the experiment. The result shows an accuracy up to 87% with a value of K = 4.

Abstract

Blood pressure measurement is a very important activity. Blood pressure determines the strength of blood flow circulating in the body. If blood pressure is too high or too low, it will cause vital impact and even lead to death. The measuring of blood pressure commonly uses mercury sphygmomanometer. Disadvantages of this instrumention are users should have good hearing and sight, depending on the sensitivity of the stethoscope, and not user-friendly. In this paper, the writers will discuss the design and development of digital blood pressure instrumentation that is user-friendly. Some of the components used in this instrumentation are MPX5050GP pressure sensor, comparator, voice circuit, and LCD circuit. The result of blood pressure measurement is displayed on the LCD and sound. With these features, user can use this instrumentation easily. The performance of this intrument was tested by comparing it with mercury sphygmomanometer. The accuracy of this instumentation is 99.33%. The advantages of this instrumentation are it doesn’t depend on the sensitivity of stethoscope and the level of blood pressure can be viewed and heard directly on the LCD and Speaker. Keywords: Blood pressure; Digital sphygmomanometer; Pressure sensor; user-friendly.

Abstract

Secara global penyakit jantung merupakan penyakit tidak menular penyebab kematian terbesar. Salah satu cara mengenali penyakit jantung adalah dengan mendiagnosis berdasarkan hasil dari elektrokardiogram (EKG) yang kemudian dianalisis oleh ahlinya. EKG merupakan gambaran dari aktivitas listrik jantung yang terdiri dari beberapa komponen. Pada penelitian ini diusulkan algoritma pembacaan waktu pada komponen EKG yang berupa durasi interval dan segmen waktu untuk mendapatkan nilainya. Nilai interval dan segmen yang didapat kemudian di proses oleh mesin inferensi Modified K-Nearest Neighbor (MKNN) untuk mendapatkan hasil diagnosis penyakit jantung.  Nilai akurasi yang didapat dari menggunakan algoritma pembacaan waktu sebagai ekstraksinya dan MKNN sebagai mesin inferensinya adalah 90.22%.

Abstract

The continuous increment of mobile communication subscribers, require a highercapacity and spectrum efficiency of the cellular system especially in an urban area where thetraffic density is high. In order to accommodate the increasing number of subscribers, smartantenna technology is used to improve system’s performance, which could increase thenumber of call and data transmission as well as simplifying the networking management. Thebasic principle of a smart antenna is to control and reduce the effect of interference toprovide the user with the highest quality of uplink and downlink signal. This can be achievedby using narrow beams with signal processing capability at the base sites and to optimize itsradiation pattern, which automatically updated according to MS movement or as signalsconditions change. In this study, two types of smart antenna were considered, which are theswitched beam systems and adaptive antenna systems. The significant difference betweenthese two systems is from the beamforming point of view. The key part of this study is todevelop a simulator for adaptive antenna systems (AAS) and switched beam systems (SBS)based on GSM 900 in order to determine the factors that could affect network’s quality andcapacity. Simulation results of different techniques are compared and the performanceevaluations of C/I are discussed. Results show that the AAS gives a better performancecompared to SBS, with average improvement of C/I around 5 to 10 dB.Keywords: smart antenna, adaptive, switched beam,C/I

Abstract

High blood disease or famous to known as hypertension almost 95% the cause is very difficult to know. One way to know the condition of our health is by checking routine to the nearest clinic or hospital. Hypertension is one of the risk factors for dangerous diseases, such as stroke, heart attack, and kidney failure. Hypertension can cause high morbidity (pain) and mortality (death), hypertension is often called silent killer disease. People with Hypertension rarely show early symptoms, and their recognition is usually through screening, or when seeking medical treatment for unrelated health problems. The cause factors of hypertension include weight and height, body fat, and alcohol levels inside of body. To know the condition of body to hypertension need a monitoring system and use tool tensimeter. In this research has been made the means of detecting factor symptoms of hypertension. After the measurements are done by each sensor then the data is processed by Arduino Microcontroller to be processed to computer via serial port (USB). On the computer data that has been sent will be processed using decision tables with databases obtained from experts, the resultin a decision will give classification of hypertension and non-pharmacological management.

Abstract

Nowadays, electronic products are being used extensively in many fields and applications. The dense population of electronic devices in human life has become a challenge for microwave engineers to ensure that their products can meet the Electromagnetic Compatibility (EMC) standards. Complex electronic products with smaller sizes and denser components will be a challenge for compliance with EMC standards. In addition, the occurrence of non-stationary emission at certain operating modes becomes a challenge for analysis. Error in analyzing EM emissions will make the products unable to meet the requirements of EMC standards; hence, they will be prohibited to be marketed. Currently, there are two methods of emission analysis, i.e. by measurement and modeling or computation. There are some problems, however, in the analysis of EM emissions regarding the area of test, complexity, DUT positioning error, installation cost, and time consumption. In this paper, the analysis techniques for EM emissions including Open Area Test Site (OATS), Anechoic chamber, Transverse Electromagnetics TEM Cell, Compact Antenna Test Range (CATR) and near field scanning are reviewed comprehensively. This survey covered EMC standards, principles of EM emission measurement techniques, advantages and disadvantages of EM emission measurement techniques, studies and applications of each technique, recommendations for which technique to be used, and challenges for future research in EM emission measurement. The final section of this paper discusses the challenges for near-field measurements related to the non-stationary emissions phenomenon. This papers also presents the challenges of how to detect and characterize them.
