There is a problem of excessive inventory in a Manufacturing Company, situated in South Africa. In this study an Inventory Management Framework (IMF) was developed. Quantitative content analysis was used to collect data. Statistical tools were used to select the fiscal year with the vast data variation for data analysis for this study.

The use of gas absorption lines as multi-wavelength references to enhance the measurement accuracy of fibre Bragg grating sensors is reported. Experiments with a three-FBG-sensor array interrogated by a tunable laser demonstrated an overall measurement accuracy of ~2 pm.
A multidisciplinary introduction to engineering design using real-life case studies.
Case Studies in Engineering Design provides students and practising engineers with many practical and accessible case studies which are representative of situations engineers face in professional life, and which incorporate a range of engineering disciplines.
A state space predictive control algorithm, with state constraints at the end-point, is evaluated on a real plant showing nonlinear behaviour. Predictive control techniques based on linear state space model description can find difficulties when applied to a real system with nonlinear behaviour, for example the controlled system may present a steady state offset or bias in the step response. We illustrate, in a real application, a multivariable extension of the constrained receding horizon predictive control (CRHPC) with an error correction on the set point in such a way to avoid the above problem. Specifically, we estimate with a Kalman filter the error between the model prediction and the real response of the plant. The benchmark in this paper is a laboratory distillation column.
The viability of using complexity science in physics education research (PER) is exemplified by (1) situating central tenets of student persistence research in complexity science and (2) drawing on the methods that become available from this to illustrate analyzing the structural aspects of students’ networked interactions as an important dynamic in student persistence. By drawing on the most cited characterizations of student persistence, we theorize that university environments are made up of social and academic systems, which PER work on student persistence has largely ignored. These systems are interpreted as being constituted from rules of interaction that affect the structural aspects of students’ social and academic network interactions from a complexity science perspective. To illustrate this empirically, an exploration of the nature of the social and academic networks of university-level physics students is undertaken. This is done by combining complexity science with social network analysis to characterize structural similarities and differences of the social and academic networks of students in two courses. It is posited that framing a social network analysis within a complexity science perspective offers a new and powerful applicability across a broad range of PER topics.
International Journal of Engineering, Science and Technology (IJEST) - an E-journal is an international peer-reviewed, electronic, online journal published by MultiCraft. The aim and scope of the journal is to provide an academic medium and an important reference for the advancement and dissemination of research results that support high-level learning, teaching and research in the fields of engineering, science and technology.
Diode laser absorption spectroscopy (DLAS) has become an important gas analysis technology, and optical fiber sensing is a novel sensing technology. Combining laser diode absorption spectroscopy and optical fiber sensing technology, the optical fiber gas sensing system based on DLAS is designed and developed. The principle of DLAS is firstly introduced, then construction and characteristics of optical fiber gas sensing system based on DLAS are indicated. Field application shows that the gas sensing system can meet requirements of measurement, and has a promising application prospect.
The aim of this study is to provide a full comprehensive study of the singular linear parameter-varying (LPV) systems and observer synthesis in a real process. The states and unknown inputs estimation problem for a binary distillation column is solved by using an LPV proportional-integral observer (PI-Observer). A singular LPV model of the process is developed. This model facilitates the design of the PI-Observer for singular LPV systems. The observer proposed is tested using experimental data of a distillation column separating an ethanol–water mixture. The results indicate that the observer is able to accurately reconstruct the product composition dynamics and the unknown inputs of the process.
The paper discusses three different approaches to uncertainty problem in static optimization task performed within optimizing control of binary distillation column. Deterministic, probabilistic and set-bounded description of the model and input uncertainty is explored. One solves optimisation task with active constraints on output variable. Follow-up controller stabilises the output at the constraint level, thus compensating the effects of uncertain solutions of the optimization task. The optimal profit is compared with expected values of the performance index computed on a basis of probabilistic representation of the uncertain quantities with dynamic compensation losses taken into account. The results point the deterministic approach to be the most useful.

The ohm's law can be successfully applied to the various circuits to analyse them. In practice, the circuits may consist of one or more sources of e.m.f. and number of electical parameters, connected in different ways. The different electrical parameters or elements are resistors, capacitors and indicators. the combination of such elements along with various sources of energy give rise to complicated electrical circuits, generally reffered as net works.
