1. CROSS-COUNTRY ANALYSIS ON WASTE GENERATION, COLLECTION SERVICE COVERAGE, INTERMEDIATE TREATMENT, AND FINAL DISPOSAL IN SOLID WASTE MANAGEMENT

Authors: MITSUO YOSHIDA

Abstract: In this paper, the trends of waste collection coverage, intermediate treatment, and final disposal of solid waste in the world are analyzed based on the cross-country analysis of waste management statistics. As a result, the improvement of waste collection service coverage strongly correlates with the increase of Human Development Index (HDI) and economic growth (GDP/capita). The introduction of intermediate treatments also correlates with economic growth, in which compost production and material recycling firstly become widespread in the low to middle-income stages, then following these, waste-to-energy incineration technology surges from middle to high-income stages. Anaerobic digestion also emerges from middle to high-income stages but in a limited scale. The method of final disposal of solid waste widely varies but in general open dumping decreases according to the economic growth, and sanitary landfilling increases

6. DESIGN OF A SUB SYNCHRONOUS OSCILLATION CONDITION PROTECTION RELAY USING TIME FREQUENCY ANALYSIS

Authors: ADITI , PRASHANT GAWANDE , SANJAY DAMBHARE

Abstract: To boost a transmission line’s capacity for power transfer, series compensation is required. However, when we use series compensation there is risk of sub-synchronous resonance (SSR). With the increasing penetration of renewable generation resources, power grids have become more susceptible to sub-synchronous resonance phenomena, especially to sub synchronous control interaction, which produces fast-growing oscillations. This leads to mechanical fatigue of the shaft on which the turbine and generator are connected. Till now, different techniques have been proposed, like eigenvalue, frequency scan, and time domain simulation to study sub-synchronous resonance. In this paper we compare methods for detection of SSR. Proposed method is Stockwell transform. Proposed methods were compared with traditional method i.e., Fast Fourier Transform (FFT). The reliability and effectiveness of the method have been validated on IEEE first benchmark model. The model was simulated in ATP and all the im

7. DESIGN AND SIMULATION OF ISOLATED CONVERTER FOR AUXILIARY POWER MODULE

Authors: OMKAR A. ACHARYA , V.N. PANDE

Abstract: Electric vehicles (EVs) use an Auxiliary Power Module (APM) as a replacement for the alternator in conventional internal combustion engine vehicles. APM takes input power from high voltage (HV) battery and provides output power to charge low voltage (LV) battery and drive the auxiliary loads. For the APM with high input voltage galvanic isolation is a requirement. Soft-switched topologies offer better efficiency and EMI performance. This paper presents selection of suitable topology for such an APM operating within an inputvoltage range of 82.5 V to 126 V. The design procedure and mathematical computation are likewise incorporated. Thedesigned converter has efficiency of 94%.

9. DESIGN AND COMPARISON OF INTEGER AND FRACTIONAL PI CONTROLLERS FOR FIELD ORIENTED CONTROL OF PMSM

Authors: MEERA MURALI , OMKAR BHANAP , SHAYOK MUKHOPADHYAY

Abstract: Permanent magnet synchronous motor is a commonly used motor in electric vehicles. This paper focuses on the design and comparative analysis of integer and fractional order proportional integral controllers on Permanent Magnet Synchronous Motor (PMSM) used for electric vehicle application. Field oriented control (FOC) is used for control of PMSM in EV application. Dynamic equations in rotor reference frame are used to obtain the state space representation of the PMSM. Perturb and disturb method is used to convert this state space representation into transfer function. Frequency responsebased approach is used to design integer order PI (IOPI) and fractional order PI (FOPI) controllers for current as well as speed loops. Four different combinations of inner and outer loops are then considered for comparative analysis of time and frequency domain response. MATLAB software is used to validate the proposed PMSM drive system. It is observed that, the FOPI controller-based system is more effe

10. EMOTIONAL VALUE AND GROWING ECONOMY

Authors: SHUICHI FUKUDA

Abstract: —Society shifts from one world to another with time. The current Industrial Society is getting close to its ceiling and many issues are emering. It is time now to consider and develop the next society. “Self-Actualization” is the highest need of us, humans and we get the greatest happiness and the feeling of achievement, when we do the job internally motivated and self-determined. In the Industrial Society, we worked for others, but we should consider making our life happy in the next society. To achieve this goal, we need to satify our emotion. But it is very much complicated and we cannot solve it mathematically. But we cope with the unexpected context in everyday life and it is enabled by our inborn instinct. If we make the most of our instinct, then we can increase emotional value and we can keep our economy growing. This paper points out the importance of instinct and how we can support it

11. EXPERIMENTAL INVESTIGATION TO CHANGE THE TYPE OF EXCITATION OF THE GENERATOR (INDEPENDENT OF EXCITATION OF THE GENERATOR (INDEPENDENT WITH SERIES) IN THE CASE OF THE ELECTRIC SYSTEM BRAKING )

Authors: BELE IOAN , BOCII SEVASTIAN LIVIU

Abstract: The braking is one of the most important duty cycles of a rail vehicle , irrespective of the type of the vehicle, i.e. a classical or a high speed one, due to the traffic safety that it must ensure and to the great diversity of factors that may influence its function. The electrical braking (with rheostat or regenerative) is characteristic for the rail stock motor vehicles and is based on the principle of reversibility in the electrical equipment. The authors present in the paper a solution obtained as a result of experiments on the electrical braking system for vehicles with frequent starts and stops. The experiments consisted in the replacement of the electrical braking system produced by an independent excitation generator with one produced by a series excitation generator

12. EMPIRICAL RELATIONSHIP TO EXPLICATE MUDFLOW BEHAVIOUR

Authors: BUDIJANTO WIDJAJA , LIVIA FLORENCIA

Abstract: Mudflow is one of the natural disasters that frequently happen in Indonesia. This flow-type of landslide occurs suddenly and moves very fast, so it can cause massive damage and loss. However, knowledge about this disaster's behavior is minimal, even though it poses a huge destructive threat. Assessment from twenty case studies is done to understand more about mudflow behavior. High plasticity silt is the soil type most likely to become mudflow. The sediment concentration by volume value for mudflow is in the range of 0.29–0.56. Eight relationships between mudflow parameters were obtained: the steeper the slope, the greater the flow distance; as the liquidity index increases, the viscosity and yield stress value will decrease; the higher the viscosity, the greater the flow width; More volume moves from sources to deposition areas over longer flow distances; as flow rate increases, flow duration decreases; the deeper the flow depth, the shorter the flow duration. Lastly, a wider flow w

13. THE BENEFITS OF UPGRADING A CONVENTIONAL BATCH HEATING SYSTEM USING MULTIPLE TEMPERATURE MEASURING POINTS ANALYSIS

Authors: COSTEL-IOAN CIOBAN

Abstract: The supply of heat to buildings in Romania and beyond is at a turning point and the main reason is the everincreasing price of fuel and electricity. In the current context, climate change, energy dependence, depletion of fossil fuel reserves and the current geopolitical context generated by the war between Ukraine and Russia are forcing national and European institutions, local and national authorities to be concerned with increasing the quality of life of citizens (or at least preserving it at its current level) and meeting the conditions for ensuring their comfort. Another important issue is the safe operation of heating systems and the provision of minimum indoor thermal comfort parameters. The long-term security of energy resources and the fight against climate change require measures for the introduction, modernisation and expansion of efficient heat supply systems. In order to achieve these objectives, conditions for the efficient use of energy resources must be developed and en

14. USER ENTREPRENEURSHIP: ACCIDENTAL ENTREPRENEURS, HOBBYISTS AND PROFESSIONALS AS INNOVATION ACTORS IN TOURISM

Authors: EINAR SVANSSON

Abstract: The paper analyzes two innovative organizations in the well-being field with recent strands of user innovation and service concepts. The Service dominant (SD) logic of marketing (Lusch and Vargo, 2008) incorporates co-creation and a strong network lens and strengthens the perspective that innovative actors can be anywhere in the network of the organization. The Lead user theory (Erich von Hippel, 1986) defines the user ahead of the population in a rising trend, and that more frequently innovates if extreme needs or tastes call for a better solution. I argue that the recent papers by Shah & Tripsas (2007) highlighting “The Accidental Entrepreneur” as a heavy user innovating and the paper by Chatterji & Fabrizio (2008) focusing on “Professional Users as Source of Innovation” can help to expand the traditional innovation concepts in line with SD logic and Lead user theory. The research method is a case-study using historical data and interviews with managers and network partners.
