In this paper we present improved training algorithms to two newly developed classifiers, reduced set vector machines and Adaboost cascade classifier applied in face detection, which are all based on learning from data. Support vector machine (SVM) has been proved to be a powerful tool for solving practical pattern recognition problems based on learning from data. Due to large number of support...

In this paper, we propose an object detection approach using spatial histogram features. As spatial histograms consist of marginal distributions of an image over local patches, they can preserve texture and shape information of an object simultaneously. We employ Fisher criterion and mutual information to measure discriminability and features correlation of spatial histogram features. We furthe...

In this work, the refrigerant R1233zd(E) (A1 ASHRAE safety code) is investigated for possible substitution of R161 (A2 in a cascade refrigeration system. The high-temperature circuit evaluated with low-temperature refrigerants R41 and R170 thermo-economic consideration. A comparative analysis combination R41-R1233zd(E) R170-R1233zd(E) presents exergy efficiency total plant cost as evaluation cr...

Punctuation prediction and disfluency prediction can improve downstream natural language processing tasks such as machine translation and information extraction. Combining the two tasks can potentially improve the efficiency of the overall pipeline system and reduce error propagation. In this work1, we compare various methods for combining punctuation prediction (PU) and disfluency prediction (...

A hierarchical approach, in which a highdimensional model is decomposed into series of low-dimensional sub-models connected in cascade, has been shown to be an effective way to overcome the ‘curse of dimensionality’ problem. The upwards propagation of information through a cascade hierarchy of Linguistic Decision Trees (LDTs) based on label semantics forms a process of cascade decision making. ...

An adsorption system driven by solar heat or waste heat can help to eliminate the use of ozone depletion substances, such as chlorofluorocarbons (CFCs) and hydro-chlorofluorocarbons (HCFCs). In recent years, adsorption system has witnessed an increasing interest in many fields due to the fact that this system is quiet, long lasting, cheap to maintain and environmentally benign. Although adsorpt...

The lack of established optimal design guidelines for turbomachinery operating in the nonideal flow regime (e.g., organic Rankine cycle turbines, compressors, compressors refrigeration systems) demands effective and efficient automated methods. Past research work focused on gradient-free methods applied to computational fluid-dynamic simulations. application adjoint method is a cost-effective a...

Machine translation services available on the Web are getting increasingly popular. Multiple translation services are often combined for intercultural communication. Furthermore, since English is most frequently used as a hub language, it is often necessary to cascade different translation services to realize translations between non-English languages. As a result, the word sense is often chang...

introduction pulmonary vein (pv) isolation is considered as a key to atrial fibrillation (af) treatment. cryoballoon ablation is an effective therapy for pv isolation for af with minimal side effects and was approved by the us food and drug administration (fda) several years ago. successful isolation of pvs during cryoablation depends on the balloon temperature and helps in early identification...

joule-thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields. in the current study, an attempt was made to indicate the effect of using inappropriate operational conditions in a cryogenic joule-thomson cooling system...
