Continuous Stirred Tank Reactor (CSTR) is amajorarea in process, chemical and control engineering. In this paper, PID and MPC controllers are designed for CSTR in order to analyze the output concentration of the system by comparing the two proposed systems using Matlab/Simulink. Comparison have been made using two desired concentration input (Random reference and step) signals with and without input side disturbance (Flow rate error). The simulation result shows that the continuous stirred tank reactor with MPC controller have better response (...) in minimizing the overshoot and tracking the desired concentration for the system without input disturbance and with the effect of the disturbance makes the continuous stirred tank reactor with MPC controller output with small fluctuations and still better than the continuous stirred tank reactor with PID controller. Finally the comparative analysis and simulation results prove the effectiveness of the continuous stirred tank reactor with MPC controller. (shrink)

Accurate and precise trajectory tracking is crucial for a quadrotor to operate in disturbed environments. This paper presents a novel tracking hybrid controller for a quadrotor UAV that combines the Adaptive and Fuzzy logic controller. The Adaptive fuzzy controller is implemented to govern the behavior of two degrees of freedom quadrotor UAV. The proposed controller allows controlling the movement of UAVs to track a given trajectory in a 2D vertical plane. The Fuzzy Logic system provides an automatic adjustment of the (...) Adaptive parameters to reduce tracking errors and improve the quality of the controller. The results showed perfect behavior for the control law to control a quadrotor trajectory tracking task. To show the effectiveness of the intelligent controller, simulation results are given to confirm the advantages of the proposed control method, compared with Fuzzy and Proportional integral derivative (PID) control methods.

Abstract: This working paper focuses on the question whether there is a therapeutic imperative that, in specific situations, would oblige us to perform genome editing at the germline level in the context of assisted reproduction. The answer to this central question is discussed primarily with reference to specific scenarios where preimplantation genetic diagnosis (PGD) does not represent an acceptable alternative to germline genome editing based on either medical, or ethical, or – from the perspective of the potential parents – moral (...) or religious grounds. This article deals with four different types of case constellations that result from these possible reasons against PGD as well as from the necessity or dispensability of a subsequent “control PGD.” These cases are discussed based on hypotheses concerning contextual factors and theoretical assumptions. In conclusion, we point out that if our assumptions are correct, there is probably no therapeutic imperative for genome editing at the germline level. We draw this rationale from the fact that germline interventions are likely not person-affecting. However, we caution the reader that our result is preliminary and needs to be more carefully examined in future work in light of the bioethical debate and potential objections. -/- // Abstract: Im Zentrum dieses Working Papers steht die Frage, ob es einen therapeutischen Imperativ geben kann, der uns, in bestimmten Situationen, verpflichten würde, eine Genomeditierung (genome editing) auf Keimbahnebene im Rahmen der assistierten Befruchtung vorzunehmen. Die Antwort auf diese zentrale Frage wird insbesondere mit Bezug auf Fälle diskutiert, in denen das Verfahren der Präimplantationsdiagnostik (PID) keine aus entweder medizinischen oder ethischen oder – aus Sicht der potentiellen Eltern – moralischen bzw. religiösen Gründen akzeptable Alternative zu einem Keimbahneingriff darstellt. Die möglichen Gründe gegen die PID sowie die Erforderlichkeit oder Verzichtbarkeit einer nachfolgenden «Kontroll-PID» ergeben vier verschiedene Fallkonstellationen, denen sich der Beitrag zuwendet. Auf Grundlage von Hypothesen zu kontextuellen Faktoren und theoretischen Annahmen diskutieren wir diese Fälle. Im Ergebnis verweisen wir darauf, dass es, wenn unsere Annahmen zutreffen, vermutlich keinen therapeutischen Imperativ zum genome editing auf Keimbahnebene gibt. Dies begründet sich daraus, dass der Keimbahneingriff vermutlich nicht als personenbezogen (person-affecting) zu bezeichnen ist. Wir weisen jedoch darauf hin, dass unser Ergebnis vorläufig ist und unter Berücksichtigung der bioethischen Debatte und möglicher Einwände genauer geprüft werden muss. -/- // Résumé: Ce Working Paper se concentre sur la question de l’existence d’un impératif thérapeutique qui, dans des situations spécifiques, nous obligerait à réaliser une édition du génome au niveau de la lignée germinale dans le cadre de la procréation assistée. Afin de répondre à cette question centrale nous développons quatre scénarios spécifiques dans lesquels le diagnostic préimplantatoire (DPI) ne représente pas une alternative acceptable à l’édition du génome germinal pour des raisons médicales, éthiques ou – du point de vue des futurs parents – morales ou religieuses. Cet article traite de quatre constellations différentes de cas résultant des raisons mises en avant pour s'opposer au DPI ainsi que de la nécessité ou de l’inutilité d’un ultérieur « DPI de contrôle » Ces cas sont discutés sur la base d’hypothèses portant sur les facteurs contextuels et sur les présupposés théoriques. En conclusion, nous soulignons que si nos hypothèses sont correctes, il n’y a probablement aucun impératif thérapeutique justifiant l’édition du génome au niveau de la lignée germinale. Nous arrivons à cette conclusion parce qu’une intervention au niveau de la lignée germinale n’est probablement pas susceptible d’affecter la personne. Cependant, nous mettons en garde le lecteur sur le fait que notre conclusion est préliminaire et qu’elle doit être examinée avec soin dans des futurs travaux instruits par le débat bioéthique et par les éventuelles objections.

The Philippines is one of the fast-growing economies in the South-East Asian and the Pacific region. This study considered eight factors: HEI PRC rate, crime rate, education, employment, health, poverty, income, and basic family amenities of the 17 regions of the country, all taken from the year 2012 databases of the Philippine Statistics Authority (PSA), the Philippine Institute for Development Studies (PIDS) and Open Data Philippines. Principal Component Analysis (PCA) generated the indices of the six factors and Cluster Analysis (CA) (...) to group regional similarities. Clustering revealed that ARMM and MIMAROPA Regions have clustered independently, in two individual clusters, while the rest of the 15 regions have clustered in two groups of five and 10. The study revealed that crime, poverty and health mortality rates have generally inverse relationships with HEI PRC percentage performance, employment, education, income and basic housing amenities.
