Implementation Of Simulink Controller Design On IRIS+ Quadrotor

Abstract : The thesis has two primary objectives. First, it develops a high-fidelity 6DOF flight dynamics model of a multi-copter UAV, and uses it for the design and implementation of the linear attitude controller onboard of an industrial quadcopter; both steps are implemented in Simulink. Second, it leverages the weakly joint efforts of MathWorks and the open-source community to build a software setup that enables rapid control software prototyping. This software architecture enables control system design and integration without the need for proficiency in embedded coding that typically utilizes high-level programming languages like C/C++. The higher impact of the dual objective is in advancing methods and tools of verifiable control system design and the embedded code generation that simplifies the V and V process. The 3DR Iris+ quadrotor, equipped with PX4 Pixhawk autopilot, is selected as the primary prototyping platform. The autopilot allows for the real-time execution of an application (attitude controller) that is auto-generated from MatLab/Simulink. This makes the Iris+ quadrotor an ideal platform for rapid flight control prototyping by using MathWorks auto code generation capability. Ultimately, the developed setup represents a convenient research and development tool that natively bridges the gap between the safety-critical flight control science and flight experimentation technology by eliminating the error-prone manual coding of embedded microcontrollers.
Active damping control of PWM CSI high power induction motor drives

In this paper, an active damping control scheme is proposed for use in high power current source inverter fed induction motor drives. The proposed scheme can effectively solve the stability problem associated with the drive using V/f (Volts per Hertz) control. By integrating the active damping control into the V/f control, the stability of the drive is substantially improved and the LC resonance caused by the inverter capacitor and motor inductance is effectively suppressed. In addition, the drive system using this scheme becomes less parameter sensitive and easy to implement. The performance of the proposed drive is investigated through eigenvalue analysis. A 5 hp prototype drive is constructed and the theoretical analysis is verified by experiments. The feasibility of using this control scheme in high power drives is also investigated.
Supply voltage scaling for temperature insensitive CMOS circuit operation

CMOS supply voltage scaling for temperature independent gate delay is investigated. It is found that the optimum supply voltage which results in temperature insensitive operation is proportional to the threshold voltage. This voltage enables a single battery cell operation. CMOS technologies with 0.35- and 0.25-/spl mu/m size features are used as examples in this study.

Trends in the epidemiology of urinary tract infections in pregnancy at a tertiary hospital in Johannesburg: Are contemporary treatment recommendations appropriate?

Background Urinary tract infections (UTIs) are common during pregnancy and are associated with maternal and foetal complications. Empiric antibiotic choices in pregnancy require consideration of efficacy and safety, resulting in limited oral options. With rapidly evolving antibiotic resistance, surveillance to guide empiric treatment recommendations is essential. Methods A retrospective analysis of urine culture isolates from the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) Obstetrics Department for 1 January 2015 to 31 December 2020 was performed. Results The top 3 pathogens were Escherichia coli, Enterococcus faecalis and Klebsiella pneumoniae. For E. coli susceptibility to cefuroxime declined (95% to 81%, p < 0.0001). Similarly, the E. coli extended spectrum beta-lactamase rate increased from 5% to 10% (p = 0.04). E. coli susceptibility to nitrofurantoin (93%) and fosfomycin (96%) remained high. In 2019, carbapenem-resistant K. pneumoniae emerged. Ampicillin susceptibility was high amongst the E. faecalis isolates. Amoxicillin-clavulanate demonstrated high levels of activity against the top 3 uropathogens. Conclusion The Essential Drug List recommended antibiotics for lower UTIs, nitrofurantoin and fosfomycin, are appropriate empiric options for E. coli, the most common uropathogen in the CMJAH obstetric population. The high rate of E. faecalis susceptibility to nitrofurantoin reported from other Gauteng tertiary obstetric patients, suggests that nitrofurantoin will provide adequate empiric cover for a large proportion of UTIs. However, the determination of the E. faecalis nitrofurantoin and fosfomycin susceptibility rates in the CMJAH obstetric population will provide useful data. Periodic surveillance at the various levels of antenatal care in different regions of South Africa and the determination of risk factors for infections with resistant uropathogens is needed.
Queer attention matters: a study on affordance from queer male media practices on Zhihu

Abstract This study examines how Chinese queer males explore various affordances on an open platform that is accessible to everyone. After recruiting 14 queer male informants for semi-structured interviews and employing the method of cyberethnography, we conducted a thematic analysis and identified three main affordances perceived by queer males on Zhihu, a Chinese question-answering online community: intragroup text-sociability, identity reflexivity, and community (un)expandability. Based on these practical findings, the study proposes the concept of “queer attention” to explain why queer males explore these specific affordances and further develops the discussion around the role of attention in influencing the generation of affordance effect.
Generalized granuloma annulare: Narrow‐band UVB phototherapy combined with tacrolimus ointment

Dear Editor, A 67-years-old Caucasian woman with Fitzpatrick skin phototype II sought medical advice for the evaluation of histology-proven generalized granuloma annulare (GGA). Physical examination showed multiple erythematous-violaceous papules and plaques with annular and arciform configuration, localized at the limbs, trunk, and neck, with particular emphasis on the extensor surface of the forearms, Figure 1. Histopathology revealed palisading histiocytic granuloma with central collagen degeneration and mucin deposition. The patient was successfully treated in another clinic with intramuscular 40 mg triamcinolone acetonide injection every 3 weeks. All the cutaneous manifestations have been characterized by a relapsing remitting trend in the last 2 years, so repeated courses of treatment were necessary to control the disease. Although the complete response associated with systemic corticosteroid she had to stop the treatment because of various metabolic side effects, including hypertension, osteoporosis, and diabetes mellitus. The patient was switched to high-potency topical corticosteroid; despite the treatment the lesions were persistent and progressive. At this time, our decision was made to start phototherapy. The Granuloma Annulare Severity Index (GASI) score at the start of the treatment was 40. She initiated treatment with narrow-band ultraviolet B (NB-UVB) phototherapy sessions, three times weekly, for 7 weeks using a cabin equipped with TL 01 lamps (Waldmann Medizintechnik, VillingenSchwenningen, Germany) and concomitant tacrolimus 0.1% ointment applied once daily. The initial dose was 0.20 J/cm, according to the phototype, which was gradually increase of 0.05–0.10 J/cm every session according to patients' tolerance, and never exceeded 1.25 J/cm. Twenty-one NB-UVB phototherapy sessions were performed (cumulative dose 20.3 J/cm), with a complete resolution of the lesions except for few elements on the extensor surface of the forearms; the GASI score after treatment was 10, Figure 1B.

Analysis of Water-Cooled Intercooler Thermal Characteristics

With the incremental power of construction machinery diesel engines, the power performance of diesel engines and the pollutant emissions from the exhaust gas have imposed increasingly stringent requirements on the intake cooling system of diesel engines. This paper compared the j/f evaluation factors for fin unit bodies of water-cooled intercooler (including straight fins and rectangular misaligned fins) by means of CFD simulation, and found that the rectangular misaligned fins had an 8% advantage in comprehensive performance. With the rectangular staggered fin intercooler, it was found that under the same conditions, the cooling efficiency of the dual-pass water-cooled intercooler is higher than that of the single-pass water-cooled intercooler, and the uniformity factor of the temperature difference field of the dual-pass water-cooled intercooler is 1.5% higher than that of the latter. The accuracy of the overall simulation of the intercooler is verified by the field test. The dual-pass and single-pass water-cooled intercooler both can maintain heat balance under working conditions, and its average air inlet temperature is 10 °C lower than that of the original air-cooled intercooler, which provides support for further reducing the engine air inlet temperature. The results provide a theoretical basis for the performance improvement of water-cooled intercoolers.
Economic Model For Production Of Eco-friendly Products From Natural Fibre Material

Petroleum-based synthetic materials such as polypropylene are normally not environmentally friendly. There is renewed interest in natural fibre as replacement for these. Agave, a natural fibre material that is locally available in South Africa, can be tapped into as it has a variety of applications in the manufacturing of eco-friendly products. About 98% of the agave plant that was previously not deemed useful now has a potential economic value and can be used as a biomass feedstock, yielding renewable and carbon neutral energy. Car manufactures and green product designers are also currently interested in agave and this has given the agave industry new vigor. This paper gives results from interviews carried out with various people involved in the production and processing of agave. A description of the processing of the plant is included. The input and output parameters as well as their inter-relationships are determined. The paper finally presents an economic model highlighting the feasibility of investing in agave industry. The model would be useful for decision making purposes by potential investors.

HR Issues and Challenges in Pharmaceuticals with special reference to India

According to PricewaterhouseCoopers report India‘s Pharmaceutical sector is estimated to touch US$ 74 billion in sales by 2020, from the current US$ 11 billion. Now, India is among the top five pharmaceutical emerging markets. Despit e rising attention on development of pharmaceutical sector in India, little attention has been paid to the role of human resource management which can serve as a vital factor for the growth of pharmaceuticals. At present there are several HR issues and challenges that are being experienced by the pharmaceutical sector. In this paper, I have analyzed several research data (i.e. collected and processed information by some other person or organizations) and case studies pertaining to pharmaceutical industry in India and found that talent management, rate of attrition, gender inequality, stress at workplace, and changing talent expectations are some of the key issues and challenges that are to be focused at. Different HR strategies should be framed to tackle this situation.

As a basis for the channel model, the time-variant linear filter model is used. Channel noise is shown to be a summation of four noise types. Figures on channel-input impedance as well as signal attenuation are given. Finally, the phase shift introduced by the channel is considered.
Efficacy of detergent-based cleaning methods against coronavirus MHV-A59 on porous and non-porous surfaces

Abstract This study evaluated the efficacy of detergent-based surface cleaning methods against Murine Hepatitis Virus A59 (MHV) as a surrogate coronavirus for SARS-CoV-2. MHV (5% soil load in culture medium or simulated saliva) was inoculated onto four different high-touch materials [stainless steel (SS), Acrylonitrile Butadiene Styrene plastic (ABS), Formica, seat fabric (SF)]. Immediately and 2-hr post-inoculation, coupons were cleaned (damp wipe wiping) with and without pretreatment with detergent solution or 375 ppm hard water. Results identified that physical removal (no pretreatment) removed >2.3 log10 MHV on ABS, SS, and Formica when surfaces were cleaned immediately. Pretreatment with detergent or hard water increased effectiveness over wet wiping 2-hr post-inoculation; pretreatment with detergent significantly increased (p ≤ 0.05) removal of MHV in simulated saliva, but not in culture media, over hard water pretreatment (Formica and ABS). Detergent and hard water cleaning methods were ineffective on SF under all conditions. Overall, efficacy of cleaning methods against coronaviruses are material- and matrix-dependent; pre-wetting surfaces with detergent solutions increased efficacy against coronavirus suspended in simulated saliva. This study provides data highlighting the importance of incorporating a pre-wetting step prior to detergent cleaning and can inform cleaning strategies to reducing coronavirus surface transmission.
Decision-Making by Technical Expert Committees for Engineering Systems *

Engineering systems are complex by definition. Information about these systems must therefore be pooled from multiple technical experts. Understanding the social dynamics underlying multi-stakeholder decisions by committees of experts is therefore crucial to the nascent field of Engineering Systems. This research argues for the importance of the study of committee decision-making to the field of Engineering Systems, and provides a computational, quantitative approach for these analyses.
ANALYTICAL MODEL FOR PREDICTING THE RESPONSE OF OLD- TYPE COLUMNS REHABILITATED WITH CONCRETE JACKETING UNDER REVERSED CYCLIC LOADING

In the study presented herein, an analytical model for predicting the response of members with old-type detailing, rehabilitated with reinforced concrete (R/C) jacketing under reversed cyclic loading is developed. The analytical model considers that there is partial con- nection between the existing member (core of the retrofitted member) and its outer R/C shell, thus allowing relative slip of the two bodies. Slip takes place at the interface between the ex- isting member and the jacket, mobilizing the shear resistance mechanisms, such as aggregate interlock, friction and dowel action. Constitutive models from the international literature are adopted to describe the mechanisms that resist relative sliding under cyclic shear reversals. Dual-section analysis is adopted to calculate the shear flow at the interface between the exist- ing member and the jacket. An algorithm is developed to estimate the flexural response under cyclic loading taking into account slip at the interfaces. The proposed algorithm is utilized for the derivation of moment - curvature response histories of members tested in the laboratory, selected from a database compiled in the framework of the present study.
Wound healing and Metabolite Profiling in Collagen-Chitosan Biomaterial-treated Chronic Wounds of Hansen’s Disease Patients

Aims: Impaired wound healing causes chronic ulcers in Hansen’s disease (HD) patients which are an unrecognized clinical manifestation and requires utmost care and attention for wound management. Collagen and chitosan biopolymers when synergistically combined produce a biologically active biomaterial for wound dressings. Hence, the aim was to prepare a collagen/chitosan (COL/CS) composite and characterize for wound healing potential in HD patients. Place and Duration of Study: CSIR-Central Leather Research Institute, Sardar Patel Road, Adyar, Chennai 600021, Southern Railway Headquarters Hospital, Constable Road, Ayanavaram, Chennai 600023, and Gremaltes Hospital, India between June 2013 and July 2020. Methodology: The HD wounds were measured by Planimetry in square cm and were also assessed for morphological structure of epidermis and collagen fiber arrangement by High Resolution- Scanning electron microscopy (HR-SEM). Proton Nuclear magnetic resonance spectroscopy (1H-NMR) for metabolite identification was studied in blood plasma samples of unwounded, untreated and treated HD patients Results: Size D (wound size on day of discharge) of the wounds were appreciably lower than Size 0 (wound size before biomaterial treatment) demonstrating efficient wound healing by the biomaterial. The morphological structure of the HD wounds showed healthy epidermal layer and thick fibers of collagen matrix in the treated wounds when compared to the controls. Key metabolites of metabolic pathways such as TCA cycle, creatine cycle and protein metabolism were identified by 1H-NMR spectroscopy Conclusion: The COL/CS wound dressing is a promising biomaterial for management of chronic wounds in Hansen’s disease.
A Fuzzy PID Control Method for the Grasping Force of an Underactuated Prosthetic Hand

The prosthetic hand which is the auxiliary equipment of the disabled people in the daily life must ensure stable grasping. Therefore, grasping force control with high accuracy and fast response is the most significant demand. With a conventional PID control, nonlinear dynamic and modeling error of prosthetic hand highly affect the control performance, causing deviation of desired force and slow response. A fuzzy PID control strategy is proposed for eliminating the influence of modeling error and implementing the grasping force control. The PID controller parameters are tuned automatically, on-line, to improve the control performance of the prosthetic hand system. The simulation and experimental results are presented to demonstrate the reliability and effectiveness of the proposed control scheme.
A Hybrid Fault Diagnosis Approach for Hydraulic Systems by using Radial basis Function Networks

To improve the reliability of hydraulic systems, a fault diagnosis approach based on radial basis function (RBF) networks was proposed in this paper. According to the target fault features extracted from a fuzzy auto-regressive with extra outputs (FARX) model, RBF networks serve as a fault classifier and the output of the RBF networks is the result of fault diagnosis. Several typical faults of hydraulic systems were used to test the fault diagnosis approach. Experiment results showed that the fault diagnosis approach is feasible and effective for improving the reliability of hydraulic systems.
