Persistent disease is defined as one that develops slowly but remains constant over time. One of the long-term diseases is chronic kidney disease. There are various stages of CKD severity. While therapy has been shown to postpone improvement, it becomes very serious over time, and if not managed properly, CKD can lead to cardiovascular disease in the early stages. If our kidneys aren't working properly, we'll need dialysis or a kidney transplant. The final stage of renal disease is kidney failure, which is treated with dialysis or a kidney transplant. The classification techniques are the main subject of this research, which includes logistic regression, tree-based decision tree, and random forest and analyzed the performance of these techniques.

Along with the restructuring of the power sector and the dissemination of the system automation and the information and communication technology, the power utilities have been encouraged to deliver more and more information to their consumers, grid operators and regulation agencies concerning the performance of the power system. This paper presents the application of protective digital relays to assist the power quality evaluation of a power system. Recommended power quality indices are used to measure the severity of short-duration voltage variation. The indices are calculated based on the registers of digital relays of different characteristics and compared to the indices calculated from a disturbance analyzer. Although the sample rate of the relays is smaller than that of the disturbance analyzer, the numeric relays can be used to assess the power quality of electric power systems.
Coating failures in petroleum refineries often seem a bit mysterious, but upon closer examination, the cause or causes are usually quite simple. This paper explores examples of coating failures and related issues that...

Is there one best way for a manufacturer to become world competitive? Since 1987, the author has been associated with the National Industry Extension Services (NIES) responsible for the delivery of the joint Commonwealth/State initiative. There may be a set of ingredients common to available packages that are the vital ones. The author is attempting to identify such an ingredient by analysing the literature and by contact with world competitive organizations and their advisers.

This paper proposes a unified mathematical framework for intelligent transceiver design. It mainly includes three most important modules in the communication system, namely, beamforming, channel estimation and Multiple-Input Multiple-Output (MIMO) detection. Firstly, the mathematical correlation behind different algorithms of a single communication module is analyzed, the purpose is to realize the unification between different algorithms of a specific communication module. Next, a cross-module unified mathematical framework is proposed. Finally, an AI architecture for the unified mathematical framework is designed, which shows that the intelligent transceiver based on the mathematical framework has higher performance.

Dynamic calibration of force transducers using sinusoidal acceleration of load mass objects requires the accurate determination of the displacement field in such objects, in order to relate accelerations measured at one or a few locations on the object to its body-averaged acceleration. We present the results of finite element calculations of such displacement fields, and show that there are significant differences from the results of first-order approximations at calibration frequencies above ≈ 1 kHz for typical load mass objects.
