Abstract:

In this study, an investigation into the factors influencing the die life cycle was prompted by the substantial costs associated with punch and matrix wear in the die used for ventilation hole cutting of the disc component, featuring MW05 material. The study focused on optimizing the life cycle through a series of experiments conducted in two stages. Initially, punch life cycle studies, including geometry and PVD surface coating, were carried out. Subsequently, matrix life cycle studies encompassing hardness, manufacturing method, surface roughness, press tonnage, and alternative material were

Abstract:

Acceleration of socio-technological changes increases demands and complexity of process modeling tasks. Developing the appropriate thinking skills is becoming a mass necessity. This paper describes a method for representation of pro- cesses, allowing systematization of such skill based on life cycle. Any process is then represented as a sequence of stag- es: perception, analysis, design, action, coordination, and evaluation. This sequence is formalized as a circular trajecto- ry on a phase space, the Cartesian axes of which are the activity and potency factors of classical semantics. As a resu

Abstract:

Enterprises in socio-economic ecosystems, like organisms in natural ecosystems, have life cycles. Since the enterprise life cycle theory was proposed, how to measure the enterprise life cycle has been a hot research topic. In order to assess the life cycle of an enterprise, a two-stage logistic model was proposed in this research, based on ecological theory and a population dynamics model. The first-stage logistic model measures the internal inhibition coefficient, intrinsic growth rate, and theoretical upper limit of enterprise development scale. The second-stage logistic model deals with the

Inventory reliability of the life-cycle assessment (LCA) model highly depends on the data quality and normally exhibits significant uncertainty. A rigorous statistical methodology was established to capture and quantify the inherent uncertainties linked to the results of the LCA model. Two sources of uncertainty, data quality and model, were identified. The former was captured by converting the deterministic value to probability density function using beta distribution according to the evaluation matrix of data quality; the latter was assessed by prescribing variation interval through defining

Development of damage can be separated into two main stages. Initially, damage increases very quickly during the first 10% of life (Stage I).

Abstract:

Three cementitious composites containing different natural fibres (flax, hemp and sea-grass) were evaluated from an environmental perspective by means of Life Cycle Assessment (LCA) method applying the cradle-to-gate approach. The environmental impact of these composites was compared to that of cementitious composites reinforced with conventional synthetic polyacrilonitrile (PAN) fibres. The functional unit was the production of one cubic meter of cementitious composites ready-for-use. The results show that generally the environmental footprint of composite with synthetic fibres is bigger than

Abstract:

The paper presents a Company Maturity Matrix as the possible interaction between two critical variables in management science: “Anti-Fragile” introduced by Nasim Taleb and measurement of cumulative experience as ability to manage company effectiveness and efficiency. The approach is to develop and represent a model as matrix coming from Boston Group Matrix. Both of variables are known and widely discussed, but the “Anti-Fragile” concept after its introduction has been isolated from other approaches, tools and measurements as a single research field. The aim of this research is to develop a sim

Abstract:

Invasive species management has developed into a highly specialized field utilizing a systems approach. It requires knowledge of their life history, growth requirements, and population dynamics that integrate their biology and control. The foundation of strategic planning for the management of invasive species is laid by demographic studies, which record the birth, growth, reproduction, and death of individuals within a population. The present study makes use of the Discrete Leslie Matrix Model to analyze the growth in the age-structured population of Euphorbia hirta, an invasive species in ag

Abstract:

The architecture of the human endometrium is extensively remodelled during the course of each normal menstrual cycle, unlike most other tissues and organs which undergo very little change during adult life. During menstruation, when loss of most of the functionalis layer occurs, there is concomitant epithelial regrowth; repair of the luminal surface is complete almost as bleeding ceases. During the proliferative phase of the cycle and under the influence of rising oestrogen levels, the stromal cells, glands and blood vessels undergo rapid proliferation which results in tissue thickening.

Abstract:

Background. In state-transition models (STMs), decision problems are conceptualized using health states and transitions among those health states after predefined time cycles. The naive, commonly applied method (C) for cycle length conversion transforms all transition probabilities separately. In STMs with more than 2 health states, this method is not accurate. Therefore, we aim to describe and compare the performance of method C with that of alternative matrix transformation methods. Design. We compare 2 alternative matrix transformation methods (Eigenvalue method [E], Schure-Padé method [SP]
