This paper discusses the knowledge integration of clinical information extracted from distributed medical ontology in order to ameliorate a machine learning-based multi-label coding assignment system. The proposed approach is implemented using a decision tree based cascade hierarchical technique on the university hospital data for patients with Coronary Heart Disease (CHD). The preliminary resu...

Introduction Chilling freshly harvested beef carcasses is necessary for food safety and quality purposes. Before mechanical refrigeration, meat either had to be consumed immediately after slaughter or be preserved through salting, curing, and/or smoking. With the advent of mechanical refrigeration and networks of refrigerated carriers, the production, processing, and distribution of carcasses a...

Supermarkets suffer serious financial losses owing to problems with their refrigeration systems. Most refrigeration units have controllers which output "high-temperature" and similar alarms. We describe a system developed to predict alarm volumes from this data in advance, and compare evolved and backpropogation-trained neural networks, and evolved rulesets for this task.

refrigerants that are used in refrigeration systems, cause environmental difficulties such as depletion of ozone layer and greenhouse effect. thus, we must find substitutes for such refrigerants, in this paper, the effect of refrigerant on the thermodynamics performance of refrigeration cycles are studied. to do this, a refrigerator that has designed for r12, is simulated. results show that pur...

Separation of ethylene from ethane in commercial processes is expensive both in capital and operating costs. This study has evaluated the feasibility of using facilitated transport membrane technology for improving the separation process. Simulation and optimization of various distillation/membrane hybrid configurations as well as stand-alone membrane cascade systems have been examined under di...

A. D. Kelly General Signal Laboratory Equipment 275 Aiken Road Asheville, NC 28806 Low temperature refrigeration mechanically and thermally stresses a compressor's wrist journal bearing. Knowledge of bearing condition would be useful for self-diagnostics or predictive maintenance, particularly in freezers used for storage of valuable biomedical products. This initial investigation considers ext...

Solar-assisted hybrid cooling systems are promising for the energy saving of refrigeration systems. In most cases, solar thermal gain is only able to power heat-driven process facilities during part working period. Therefore, reduction compressor strongly depends upon duration processes, which has not been addressed properly. Motivated by such a knowledge gap, thermodynamic understanding solar-...

One can construct any finite-state machine as a cascade interconnection of machines whose inputs either permute the states or reset them all to one state. Each permutation group needed in the construction is a homomorphic image of a group generated by the action of a set of input sequences on a state subset of the original machine. Proofs of these facts will be given and their application to th...

The output of the absorption refrigeration system driven by exhaust gas is unstable and efficiency low. Therefore, it necessary to keep performance systems in a stable state. This will help predict dynamic parameters thus control system. paper presents machine-learning algorithm for predicting key an ammonia–water Three new algorithms, Elman, BP neural network (BPNN), extreme learning machine (...
