  Trends in Technical & Scientific Research Abstract This paper will demonstrate how to illustrate poles and zeros of a filter's transfer function as a 3D surface and how this facilitates an understanding of the relationship between the filter's amplitude response and the poles'/zeros' locations in s-space. The transfer function, in Laplace representation, is plotted as a function of the real and imaginary parts of the complex frequency s. This is exemplified for a Chebyshev-II low pass filter. Keywords: Laplace transform; Poles; zeros; Transfer function; Bode plot; MATLAB; Filter Abbreviations: PBL: Problem-Based Learning; LTI: Linear Time-Invariant Introduction Transforms are probably one of the most versatile engineering tools as they facilitate a visualization of signals in frequency space. The complexity of the subject is widely recognized by students and teachers in engineering disciplines all over the world. It has...

  Trends in Technical & Scientific Research   Abstract Ripening of climacteric fruits is found to be a major hitch to enhance the commercial value of several countries. As it is considered to be one of the most abundantly consumed fruit varieties, it is imperative to increase the shelf life of the climacteric fruits. The significant reason for ripening is the production of ethylene hormone in the fruits. The commercial value of these fruits seems to be high and the export rate has also been drastically increasing due to the demand. Currently, CRISPRi is the emerging technology to show the prospect to silence the Aminocyclopropane- 1-carboxylic acid synthase gene which is mainly responsible for the ethylene biosynthesis, thus this process will retain the freshness of the fruits and thereby the ripening will also be delayed. This review majorly discusses about the existing methods and also focuses on new approach to increase the shelf life of climacteric frui...

  Trends in Technical & Scientific Research Abstract Nature inspired meta-heuristic based approaches are likely to dominate the conventional numerical and deterministic techniques. This paper presents a short review on the applications of the evolutionary computing tools and bio-inspired techniques for solving communication engineering problems. Primarily, the design issues of electromagnetic systems and techniques in image processing are summarised and the discussion is confined to these areas only. Keywords: Communication engineering problems; Multi-objective; Thresholding; Electromagnetics Introduction Meta-heuristic approaches are not problem specific or otherwise treated as problem independent techniques. Hence the take the credit of providing solutions which are sustainable as well as affordable with high degree of reliability and modularity. A design problem typically takes the design variables as inputs which define the dimensi...

  Trends in Technical & Scientific Research   Abstract In this paper, the recent advances in removal of phenol from water are briefly reviewed. The removal of phenol could be attained by adsorption, photocatalysis, ozonation, and different forms of Fenton reactions. However, the choice of the appropriate method is dependent on the initial concentration of phenol. Emphasis is given to the reports that include optimization of operating conditions and cost estimation. The merits and limitations were discussed to clarify the favorability of each method. Keywords: Adsorption; Fenton; Phenol; Photocatalysis Abbreviations: AOPs: Advanced Oxidation Processes; PAC: Powdered Activated Carbon; GAC: Granular Activated Carbon; PHAp: Porous HydroxyApatite; FAp: Fluoro Apatite; WC: Wood Charcoal; RHA: Rice Husk Ash. Introduction Phenolic compounds exist in the wastewater of many industries such as resins, pharmaceuticals, paint, petrochemical ...

  Trends in Technical & Scientific Research Abstract Objective: To explore the self-satisfactory service and association of emergency medical technicians at facing emergency dispatch when encountering international tourists. Method: Within the period from September to November in 2016, we delivered 970 questionnaires to Emergency Medical Technicians (EMT) who worked in the fire departments of Taipei City (220 copyies), Kaohsiung City (540), and Chiayi County (210). A total of 937 eligible respondents completed their responses with a return rate of 96.59%. Data including personal demography, technician expertise ability, emergency experience (34 items), foreign language ability, self-satisfactory service level, and suggestions to the issue for improving ambulance services treating international tourists (6 items) were collected. We (1) proposed a model with 7 hypotheses and used Smart-PLS software to examine their path coefficients effective, and applied Rasch mod...
