Sistem keamanan merupakan hal yang sangat dibutuhkan pada RFID. Dalam penggunaan RFID dimanfaatkan sebagai alat otentikasi user yang bisa memberikan akses lebih pada suatu sistem. Apabila hak otentikasi dipergunakan untuk hal yang salah maka hal itu akan sangat berbahaya. Pola yang digunakan adalah mengirimkan data ID Tag RFID sebagai kode otentikasi yang unik. ID Tag RFID akan dikirim dari client ke server dengan menggunakan skala jaringan lokal. Pengiriman data ID Tag RFID dapat dilakukan dengan menggunakan media transmisi nirkabel. Ketika dalam proses pengiriman, pihak lain dapat mencuri data dengan teknik sniffing. Untuk meminimalisir resiko pencurian data tersebut dapat diterapkan metode enkripsi data dengan algoritma Triple-DES (3DES). Algoritma 3DES adalah suatu algoritma pengembangan dari algoritma DES (Data Encryption Standard). Perbedaan DES dengan 3DES terletak pada panjangnya kunci yang digunakan. Pada DES menggunakan satu kunci yang panjangnya 56-bit, sedangkan pada 3DES menggunakan 3 kunci yang panjangnya 168-bit (masing-masing panjangnya 56-bit).

Design and Analysis of Different Optical Attocells Deployment Models for Indoor Visible Light Communication System

Visible light communication (VLC) is a promising candidate that is expected to revolutionize indoor environment communications performance and fulfill fifth generation and beyond (5GB) technologies requirements. It offers high and free bandwidth, electromagnetic interference immunity, low-cost front end and low power consumption. Also, VLC has dual functions that could be utilized in both illumination and communication concurrently. The number of optical attocells (OAs) and their deployment in the room represent the main issue that should be taken into consideration in designing an optimal VLC system. In this paper, we have introduced a new model of five OAs in the typical room. In addition to an investigation of various optical attocells (OAs) deployment models, in which a multi-variable evaluation was performed in terms of received power, illumination, SNR and RMS delay spread in order to determine the optimal OAs model. Also, various modulation schemes performances were investigated which included NRZ-OOK, BPSK, and QPSK in order to improve the BER performance. Results indicated that BPSK modulation had superior BER performance when compared with all OAs models. Further, a comprehensive results analysis and comparison of all proposed models was conducted over various parameters, in which our new proposed OAs model achieved an optimal performance in comparison with the other models

Liquid slosh control by implementing model-free PID controller with derivative filter based on PSO

Conventionally, the control of liquid slosh system is done based on model-based techniques that challenging to implement practically because of the chaotic motion of fluid in the container. The aim of this article is to develop the tuning technique for model-free PID with derivative filter (PIDF) parameters for liquid slosh suppression system based on particle swarm optimization (PSO). PSO algorithm is responsible to find the optimal values for PIDF parameters based on fitness functions which are Sum Squared Error (SSE) and Sum Absolute Error (SAE) of the cart position and liquid slosh angle response. The modelling of liquid slosh in lateral movement is considered to justify the design of control scheme. The PSO tuning method is compared by heuristic tuning method in order to show the effectiveness of the proposed tuning approach. The performance evaluations of the proposed tuning method are based on the ability of the tank to follow the input in horizontal motion and liquid slosh level reduction in time domain. Based on the simulation results, the suggested tuning method is capable to reduce the liquid slosh level in the same time produces fast input tracking of the tank without precisely model the chaotic motion of the fluid

In Silico Study Of Curcuminoid Compounds In Turmeric (Curcuma longa) Plants As Halal Anticoagulant Active Ingredients

Background: Thrombosis is a condition when there is a reduction in the flow of blood fluid in the blood vessels that occurs due to the process of forming blood clots. One of the drugs most often used as an anticoagulant is enoxaparin. Enoxaparin itself is obtained by depolymerizing the base of heparin benzyl ester which is derived directly from the intestinal mucosa of pigs so that its use triggers a lot of controversy by Muslims. The mechanism of action of enoxaparin is to act as an antithrombin III catalyst which functions to inhibit the formation of blood clots by factor X. The curcumin compound in turmeric is known to have the ability as an anticoagulant drug by inhibiting the formation of factor Xa by factor X. Objectif :This study aims to predict physicochemical properties, predict toxicity, and predict the antiviral activity of 8 curcumin-derived compounds in turmeric against antithrombin III receptors (GDP ID: 1R1L) and factor X (GDP ID: 5VOF). Methods :Prediction of physicochemical properties is carried out using the SwissADME application and referring to Lipinski's five laws . Furthermore, the toxicity class was carried out using the pkCSM Online Tool and Protox Online Tool applications. Prediction of the antiviral activity of compounds was carried out using the Molegro Virtual Docker (MVD) application.Results:The results of the LD50 value and the classification of toxicity classes were classified according to GHS. 8 compounds derived from curcumin belong to toxicity classes 4 and 5. Antithrombin III receptors (GDP ID: 1R1L) and factor X (GDP ID: 5VOF were said to be valid because they had RMSD values below < 2 Å. Conclusion :The results showed that cyclocurcumin compounds were predicted to have good potential anticoagulant activity.Background: Thrombosis is a condition when there is a reduction in the flow of blood fluid in the blood vessels that occurs due to the process of forming blood clots.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

PSO fined-tuned model-free PID controller with derivative filter for buck-converter driven DC motor

Traditionally, the PID controller parameters are tuned heuristically based on time response behavior of the system. This method is tiresome job and can cause undesirable system response. Therefore, this research suggests the tuning method of a model-free PID controller with derivative filter (PIDF) by implementing Particle Swarm Optimization (PSO). This tuning method is applied to buck-converter driven DC motor control. The speed of DC motor is controlled by PIDF controller. The parameters of PIDF controller are fine-tuned by implementing PSO algorithms. The fitness functions of the algorithm are evaluated based on Sum Square Error (SSE) and Sum Absolute Error (SAE). The state-space representation of buck-converter/DC motor is considered to confirm the design of the control method. The results of the proposed tuning method are compared with PI controller and PIDF controller tuned by PID Tuner Simulink. The time response specifications of angular velocity, armature current and duty cycle input energy are considered as a control scheme performance. Finally, the suggested tuning technique promises a very minimum duty cycle energy and a fast input tracking of DC motor angular velocity
