Analysis and correction of voltage profile in low voltage distribution networks containing photovoltaic cells and electric vehicles

Voltage drop and rise at network peak and off–peak periods along with voltage unbalance are the major power quality problems in low voltage distribution networks. Usually, the utilities try to use adjusting the transformer tap changers as a solution for the voltage drop. They also try to distribute the loads equally as a solution for network voltage unbalance problem. On the other hand, the ever increasing energy demand, along with the necessity of cost reduction and higher reliability requirements, are driving the modern power systems towards Distributed Generation (DG) units. This can be in the form of small rooftop photovoltaic cells (PV), Plug–in Electric Vehicles (PEVs) or Micro Grids (MGs). Rooftop PVs, typically with power levels ranging from 1–5 kW installed by the householders are gaining popularity due to their financial benefits for the householders. Also PEVs will be soon emerged in residential distribution networks which behave as a huge residential load when they are being charged while in their later generation, they are also expected to support the network as small DG units which transfer the energy stored in their battery into grid. Furthermore, the MG which is a cluster of loads and several DG units such as diesel generators, PVs, fuel cells and batteries are recently introduced to distribution networks. The voltage unbalance in the network can be increased due to the uncertainties in the random connection point of the PVs and PEVs to the network, their nominal capacity and time of operation. Therefore, it is of high interest to investigate the voltage unbalance in these networks as the result of MGs, PVs and PEVs integration to low voltage networks. In addition, the network might experience non–standard voltage drop due to high penetration of PEVs, being charged at night periods, or non–standard voltage rise due to high penetration of PVs and PEVs generating electricity back into the grid in the network off–peak periods. In this thesis, a voltage unbalance sensitivity analysis and stochastic evaluation is carried out for PVs installed by the householders versus their installation point, their nominal capacity and penetration level as different uncertainties. A similar analysis is carried out for PEVs penetration in the network working in two different modes: Grid to vehicle and Vehicle to grid. Furthermore, the conventional methods are discussed for improving the voltage unbalance within these networks. This is later continued by proposing new and efficient improvement methods for voltage profile improvement at network peak and off–peak periods and voltage unbalance reduction. In addition, voltage unbalance reduction is investigated for MGs and new improvement methods are proposed and applied for the MG test bed, planned to be established at Queensland University of Technology (QUT). MATLAB and PSCAD/EMTDC simulation softwares are used for verification of the analyses and the proposals.
Loudness of fountain and road traffic sounds in a city park

Auditory masking of unwanted sounds by wanted sounds has been suggested as an approach to soundscape improvement. Anecdotal evidence exists on successful applications, for instance use of fountain sounds for masking road traffic noise in urban parks. However, basic research on auditory masking of environmental sounds is lacking. Therefore, we conducted two listening experiments on auditory masking, using binaural recordings from a city park in Stockholm exposed to traffic noise from a main road and sound from a large fountain located in the centre of the park. In Experiment 1, 12 listeners assessed the loudness of road traffic noise and fountain sounds from recordings at various distances from road, with or without the fountain turned on. In Experiment 2, the same listeners assessed loudness of manipulated sound levels of singular or combined road traffic or fountain sounds. The results of Experiment 1 showed that the fountain sound reduced the loudness of road traffic noise close to the fountain, and that the fountain sound was equally loud or louder than the road traffic noise in a region 20-30 m around the fountain. This suggests that fountain sounds may add to the quality of city park soundscape by reducing the loudness of the (presumably unwanted) traffic noise. On the other hand, results from both experiments showed that road traffic noise was harder to mask than fountain sound. Furthermore, Experiment 2 showed that partial loudness of both sources was considerably less than expected from a model of energetic masking. This suggests that informational masking due to target-masker similarity may reduce the overall masking effect of environmental sounds.
Automatic control system for bogie truck assembly manufacturing process

A new control system for bogie truck assembly manufacturing process has been developed. The characteristics of the system are described. The system carries out two control functions in the manufacturing process line which three types of bogie truck assembly frames are produced: 1) the best pathway which is indicated to the automatic guided vehicle (AGV), and 2) the starting point indication to both the gas cutting robot and the arc welding robot. The system brings about an actual and practical use for the pre-programmed robot teaching system: 1) the function which automatically sets up the robot position, the angle of weld torch and the weld condition; and 2) the function which transmits the robot's various program functions through a local area network adjusting to the arrival time of the frame carried by the AGV. This system has achieved a reduction of labor, robot teaching time and an improvement in production efficiency. <<ETX>>
Preliminary Structural Design - Defining the Design Space

Abstract : A series of studies were performed to evaluate the application of finite element-based analysis and optimization methods to the preliminary design of lightweight, aerospace structures. Either the internal structural arrangement or the structural materials were used as the design variables in each concept study. The concepts considered ranged from truss structures such as a helicopter tail-boom or complex space truss to a series of semi-monocoque lifting surfaces. Both static and dynamic constraints were used in the design of these concepts. Multidisciplinary optimization and analysis procedures were used to develop detailed information from finite element models for each structural concept. From this detailed design data neural network representations of the design space were developed for the particular problem. The neural networks were then coupled with either simulated annealing or numerical search optimization techniques to identify improved design concepts.

Integrating Drone Technology in Service Learning for Engineering Students

Future engineers shall not only good at knowledge and technology but also good at other attributes such ethical, professional as well as managing people and emotion. Service learning is an effective education model to develop more holistic engineers. However, there is a lack of service learning framework that integrates technology, in order to achieve the acquisition of the above attributes. This paper describes how drone technology is disseminated by engineering students to the public through a service learning programme. Document analysis of the course information, project reports, and students’ reflections were employed in this study to identify the learning process and attributes developed by the students. the students went through 6 phases of service learning implementation. Results show that the service learning has enhanced the students’ learning, sense of responsibility, accountability, and international exposure. These are essential to develop good engineers in the future.

Aid and the environment: Uganda

This paper seeks to (i) establish the areas in which aid from the major donors is concentrated; (ii) examine how aid has been allocated to the environmental sectors, and (iii) review the factors behind the success of environmental projects. Using data from the Aiddata.org database, the distribution of environment-related aid, commitments and disbursements from the major donors over the period 2005–11 is examined. Recipients of aid and donors were interviewed to learn their perceptions on aid flows and the success of environmental projects. The analysis shows that although many of the key donors commit aid to environmental sectors, there was considerable non-disbursement by both multilateral and bilateral donors; a small percentage of aid from multilateral donors was geared towards the environment. Strong involvement of local communities in projects is a key to the success of environmental projects.

In this paper, the miniaturized the linear polarization and the circular polarization microstrip antennas, which are the two ends in the resonance length direction or all the four-ends were folded are designed and fabricated at the resonant frequency of 1.575 GHz(fur GPS system). For the linear polarization microstrip antenna, the antenna was bent. downward so that the visible length(=L) was reduced by . The folded antenna was folded toward the center of the antenna once again. In this case, the visible length reduction rate, gain, -10 dB bandwidth, E-plane and H-plane HPBW were , 5.12 dBd, , respectively. For the circular polarization microstrip antenna, the folded structure of the linear polarization antenna was applied to all the few directions. For the most efficiency the folded bottom surfaces were designed in a triangular shape. In this case, the visible area reduction rate, gain, -10 dB bandwidth, and HPBW in horizontal polarization of the z-x plane and the z-y plane were , respectively. Therefore, we have confirmed that the folded structure is suitable fer the miniaturization of the microstrip antenna.
Antibiotic susceptibility pattern of bacteria isolated from patients of respiratory tract infection in a tertiary care hospital of Eastern India

Background: Respiratory tract infections have been one of the commonest types of infections affecting the Indian population. With antibiotic resistance being a global threat and challenge to healthcare, concerns over skilful and judicious use of existing antibiotics have been on rise. Update on region specific bacterial susceptibility pattern is thus a need. The present study was planned to identify the common pathogens responsible for the respiratory tract infection and their antibiotic susceptibility patterns.Methods: A prospective study was carried out, where subjects with lower respiratory tract (LRT) infection admitted in the Intensive Care Unit in the tertiary care centre in Eastern India during the one-year period were enrolled in the study. Samples such as sputum, suction tip, endotracheal aspirate, bronchial aspirate and pleural fluid were obtained under aseptic precautions and were processed. The bacterial isolates were subjected to susceptibility testing by standard Kirby Bauer disc diffusion methods. The susceptibility patterns of the bacterial pathogens were determined.Results: Out of 234 processed samples, klebsiella (33.44%) was found to be commonest pathogen isolated from all the sites followed by Pseudomonas, staphylococcus and others. Amongst the penicillin group of antibiotics, ampicillin showed highest activity against pseudomonas and E. coli respectively. Antibiotics like penicillin G, ampicillin/sulbactam and amoxicillin/clavulanic acid combination showed lower susceptibility towards most pathogens. Amongst broad spectrum antibiotics, amikacin showed high susceptibility towards pseudomonas species followed by chloramphenicol and tetracycline.Conclusions: With changing trends in microbiological patterns of responsible organisms, knowledge regarding antibiotic susceptibility pattern needs to be regularly revised, thus ensuring prompt initiation of adequate and appropriate antibiotic treatment with better patient outcomes.
Effect of management system on behaviour and productivity of broiler chickens.

Compared to other sectors of animal production, the poultry sector is characterized by rapid genetic, technological and nutritional progress, which enabled breeders to shift from small-scale production to intensive production in specialized commercial farms. The current intensive methods of poultry production, which are aimed to maximize profits, make use of the latest technological solutions that facilitate work and make maximum demands on avian productivity. However, they do not always satisfy the natural needs of animals and result in low welfare levels (Sanotra et al., 2001; Rauw et al., 1998). According to Dawkins (1999) and Duncan (2002) the behaviour of birds is the most important indicator of welfare, although production results also reflect welfare levels. The aim of the present study was to determine the effect of management system on the behaviour and productivity of broiler chickens, and thus on their welfare.

Simplified ATPG and fault simulation algorithms, reduced test set sizes, and increased fault coverage are achieved with I {sub DDQ} testing for stuck-at faults. In addition, I {sub DDQ} testing will detect logically redundant and multiple stuck-at faults, and improve the detection of non-stuck-at fault defects. 17 refs., 6 figs., 6 tabs.
Solvent Extraction Techniques of Lipid from Algal species in Wastewater Treatment Station

Biodiesel production process relies of various key steps one of which is the lipid extraction from microalgae cells using economic techniques. In this study, Algal community structure and physicochemical parameters of the wastewater ‎treatment plant (Beni-Suef, Egypt), are determined from March 2016 to February ‎‎2017. In this study, we focused on the lipid extracted from wild mixed culture of Chlorella sp. which is the dominant from December 2016 to February 2017. Lipid content and fatty acid profiling of Chlorella sp. are investigated using three different methods (1) conventional extraction (CE), (2) ultrasonic assisted extraction (UAE) and (3) microwave assisted solvothermal extraction (MASE). MASE showed the highest lipid yield of ‎37.9±0.13%. SEM micrographs showed that MASE had the most distributive effect for algae cells compared to UAE and CE. Six different solvents are tested for MASE technique namely hexane: isopropanol (3:2), hexane: ethanol (1:1), chloroform: methanol (1:1), diethyl ether, ethanol and methanol. A strong linear relation between the direct electric constant and yield percent is obtained with methanol showing the highest yield. The GC-analysis of extracted lipids shows that methanol resulted in the highest percentage of palmitic acid (45.5%). The chemical composition of extracted lipids shows ‎promise towards further conversion to biodiesel. ‎
PILOTAGE IN THE PORT OF NEW YORK

Abstract : The report presents the results of a study of pilotage in the Port of New York. A major goal was to identify pilotage information, its source, the way it is used, and how it relates to the pilots' command orders. Seventeen transits in six areas of the harbor were recorded on video tape. In edited form they provide more than 24 hours of detailed descriptions of piloting events. Discussions are presented of the navigation problems in the major harbor areas and the types of information the pilots use for their maneuvering decisions. It was concluded that three interacting sources of information form the basis for the decision process: local knowledge, transit specific information, and knowledge of shiphandling. His local knowledge permits the pilot to maintain orientation, fix position, and anticipate dynamic characteristics of the environment. Transit specific information builds before and during the transit and is a source of information about the dynamics of the environment, the ship, and their interactions. Shiphandling knowledge serves as a background for most order decisions. It was concluded that there are five basic conning positions that have important implications for navigation and bridge design and layout. It was concluded that technical advances in propulsion control are not being fully utilized to meet the navigation requirements in pilotage. (Author)
Atomically Layered and Ordered Rare-Earth i-MAX Phases: A New Class of Magnetic Quaternary Compounds

In 2017, we discovered quaternary i-MAX phases—atomically layered solids, where M is an early transition metal, A is an A group element, and X is C—with a (M12/3M21/3)2AC chemistry, where the M1 and M2 atoms are in-plane ordered. Herein, we report the discovery of a class of magnetic i-MAX phases in which bilayers of a quasi-2D magnetic frustrated triangular lattice overlay a Mo honeycomb arrangement and an Al Kagome lattice. The chemistry of this family is (Mo2/3RE1/3)2AlC, and the rare-earth, RE, elements are Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, and Lu. The magnetic properties were characterized and found to display a plethora of ground states, resulting from an interplay of competing magnetic interactions in the presence of magnetocrystalline anisotropy.
Grid-independent High Resolution Dust Emissions (v1.0) for Chemical
Transport Models: Application to GEOS-Chem (version 12.5.0)

Abstract. The nonlinear dependence of the dust saltation process on wind speed poses a challenge for models of varying resolutions. This challenge is of particular relevance for the next generation of chemical transport models with nimble capability for multiple resolutions. We develop and apply a method to harmonize dust emissions across simulations of different resolutions by generating offline grid-independent dust emissions driven by native high-resolution meteorological fields. We implement into the GEOS-Chem chemical transport model a high-resolution dust source function to generate updated offline dust emissions. These updated offline dust emissions based on high-resolution meteorological fields can better resolve weak dust source regions, such as in southern South America, southern Africa, and the southwestern United States. Identification of an appropriate dust emission strength is facilitated by the resolution independence of offline emissions. We find that the performance of simulated aerosol optical depth (AOD) versus measurements from the AERONET network and satellite remote sensing improves significantly when using the updated offline dust emissions with the total global annual dust emission strength of 2,000 Tg yr−1 rather than the standard online emissions in GEOS-Chem. The offline high-resolution dust emissions are easily implemented in chemical transport models. The source code is available online through GitHub: https://github.com/Jun-Meng/geos-chem/tree/v11-01-Patches-UniCF-vegetation . The global offline high resolution dust emission inventory is freely available (see Code and Data Availability section).
