TL;DR: This paper extends the theory of median, order-statistic (OS), and stack filters by using mathematical morphology to analyze them and by relating them to those morphological erosions, dilations, openings, closings, and open-closings that commute with thresholding.
Abstract: This paper extends the theory of median, order-statistic (OS), and stack filters by using mathematical morphology to analyze them and by relating them to those morphological erosions, dilations, openings, closings, and open-closings that commute with thresholding. The max-min representation of OS filters is introduced by showing that any median or other OS filter is equal to a maximum of erosions (moving local minima) and also to a minimum of dilations (moving local maxima). Thus, OS filters can be computed by a closed formula that involves a max-min on prespecified sets of numbers and no sorting. Stack filters are established as the class of filters that are composed exactly of a finite number of max-min operations. The kernels of median, OS, and stack filters are collections of input signals that uniquely represent these filters due to their translation-invariance. The max-min functional definitions of these nonlinear iliters is shown to be equivalent to a maximum of erosions by minimal (with respect to a signal ordering) kernel elements, and also to a minimum of dilations by minimal kernel elements of dual filters. The representation of stack filters based on their minimal kernel elements is proven to be equivalent to their representation based on irreducible sum-of-products expressions of Boolean functions. It is also shown that median filtering (and its iterations) of any signal by convex 1-D windows is bounded below by openings and above by closings; a signal is a root (fixed point) of the median iff it is a root of both an opening and a closing; the open-closing and clos-opening yield median roots in one pass, suppress impulse noise similarly to the median, can discriminate between positive and negative noise impulses, and are computationally less complex than the median. Some similar results are obtained for 2-D median filtering.

TL;DR: An overview of the human body thermoregulatory system as well as the mathematical modelling of heat exchanged between human body and its environment in the situations of both awaked and sleeping people is presented.
Abstract: This paper presents a literature review of thermal comfort. Both rational and adaptive thermal comfort approaches are presented. An overview of the human body thermoregulatory system as well as the mathematical modelling of heat exchanged between human body and its environment in the situations of both awaked and sleeping people is presented.

TL;DR: In this paper, the authors review overall models for maintenance management from the viewpoint of one who believes that improvements can be made by regarding maintenance as a "contributor to profits" rather than "a necessary evil".
Abstract: Reviews overall models for maintenance management from the viewpoint of one who believes that improvements can be made by regarding maintenance as a “contributor to profits” rather than “a necessary evil”. The reasons why maintenance is such a “Cinderella function” are largely historical and can mostly be overcome by new information technology (IT) and its falling cost. Progress is now being held up by outdated notions of what is economically possible in data acquisition and analysis, and failure to revise basic maintenance and reliability concepts, some of which are now 30 years out‐of‐date. Integrated IT permits mathematical optimisation of supra‐departmental management decisions, e.g. co‐planning of production with maintenance, overhaul/renewal of machinery and improvement of product performance/quality. Life‐cycle profit (LCP) is a fair measure of overall effectiveness that emphasises the value rather than the cost of terotechnological activities.

TL;DR: A relatively large number of studies discussed here have revealed the possible areas where this phytochemical constituent can exhibit its therapeutic activities in the treatment of chronic ailments or diseases including diabetes, cancer, depression, hypertension and hypercholesterolemia.
Abstract: Importance of the field: The use of traditional medicines of natural origin is being encouraged for the treatment of chronic disorders, as synthetic drugs in such cases may cause unpredictable adverse effects. Berberine, a traditional plant alkaloid, is used in Ayurvedic and Chinese medicine for its antimicrobial and antiprotozoal properties. Interestingly, current clinical research on berberine has revealed its various pharmacological properties and multi-spectrum therapeutic applications.Areas covered in this review: An extensive search in three electronic databases (Unbound Medline, PubMed and ScienceDirect) and internet search engines (Scirus and Google Scholar) were used to identify the clinical studies on berberine, without any time constraints. This review elaborates the recent studies which reveal that with time, the drug has evolved with superior therapeutic activities. In addition, this review will also attract the attention of formulation scientists towards the issues and challenges associated ...
