Full textAbstract:
This study quantifies the effluents generated during processing in three industry types, estimates the energy potential from the quantified effluents in the form of biogas generation, and determines the economic viability of the biogas recovered. Data were procured from the relevant scientific publications to quantify the effluents generated from the production processes in the industry types examined, using industrial process calculations. The effluent data generated are used in the 2-module biogas energy recovery model to estimate the bioenergy recovery potential within it. Economic and financial analysis is based on a cash-flow comparison of all costs and benefits resulting from its activities. The effluents generated an average daily biogas of 2559 Nm3/gVS, having a daily potential combined heat and power of 0.52 GWh and 0.11 GWh, respectively. The life cycle analysis and cost-benefit analysis show the quantity of emissions avoided when using the effluents to generate heat and power for processes, along with the profitability of the approach. Conclusively, the study shows that the use of biomass effluents to generate biogas for Combined Heat and Power (CHP) is a viable one, based on the technologies of a reciprocating engine, gas turbine, microturbine, and fuel cell. However, it is recommended that the theoretical estimation be validated using a field-scale project.

Full textAbstract:
Biogas is a product of decomposition of organic matter during the process of anaerobic digestion (AD). The main components are methane and carbon dioxide. The methane content in the biogas enables it to be used as fuel which can be converted to heat and electricity. The biogas generated by the anaerobic digesters has the potential to be redirected from the flaring facilities to renewable energy (RE) facilities. The biogas may then be used to generate electricity, which in turn can operate the sewage treatment plant (STP) itself. However, feedbacks from the sewerage industry indicated that heavy investments are needed for any RE initiatives on biogas generated by sewage sludge. In order to find the cost effective way of generating energy from biogas, fundamental relationships are necessary to enable development of prototype in the future. Thus, this paper presents a study to establish the relationship between the volume of sludge and the amount of power and energy that can be generated.

Full textAbstract:
Cogeneration is the idea of converting two forms of energy from one fuel. In the sugar industry from bagasse two forms con- verted are heat and electrical power. The sugar industries utilise bagasse to generate power and to operate the plant . Here the bagasse serves as a fuel to the Boiler and this power consumption is known as captive power generation. The so generated power will be more than the power required for the running of the industry. The remaining excess power can be fed to the power grid as a power export.The actual site survey of different bagasse cogeneration plants has been carried out and included in this review. Also, this paper reviews the performance of the bagasse cogeneration plants all over the world. The review includes not only study on the power genera- tion plants but also throws an insight to identify the scope for the study on the performances of the cogeneration plants in Karnataka based on the global perview. The effective and efficient utilisation of the bagasse cogeneration plants could be identified for the im- provement of the performance of the cogeneration plants and also the economics of running a sugar industry.

Full textAbstract:
High-power plasma power supply is very useful for many industrial and medical applications. Plasma is generated artificially in the laboratory or industry by applying the electric or magnetic field. In this manuscript, we presented the simple 4T analog MOS control high voltage high frequency inverter circuit as a plasma power supply using modulation index technique. The presented plasma power supply operated at 25 kHz frequency and 10 kV peak to peak voltage. It generates a 0 V to 10 kV controllable electric field. The generated electric field is applied and produces plasma, which can be used for many industrial applications. A 10 kV to 5 kW plasma power supply has been practically developed based on the proposed topology and experimentally tested and, additionally, excellent output power conversion efficiency is achieved. From these results, the 4T analog MOS control high voltage high frequency (HVHF) plasma switching power supply is verified.

Full textAbstract:
This paper explores the tension between consumer power and surveillance through an analysis of group buying websites. These websites celebrate the power of the consumer generated through bulk purchases. Underlying the rhetoric about the autonomous consumer, however, is the systematic practice of buying, selling and reflecting consumer information. Through an examination of available promotional materials, websites and privacy policies, as well as interviews with representatives from group coupon companies, this article outlines a number of concerns surrounding the ways that digital surveillance techniques are being used, and have the potential to be used, to define consumer interests. The article argues that such practices are particularly problematic when they are couched in the rhetoric of consumer freedom and power. The article concludes by suggesting emerging industry trends, including industry consolidation and geolocation technology, which raise additional questions about how companies shape consumer behavior.

Full textAbstract:
The establishment of smart grids requires special attention to the safety of power industry facilities and the reduction in their negative impact on personnel and the environment. A significant factor of such an impact is the considerable intensities of electromagnetic field (EMF) generated by such facilities. In the context of power industry digitalization, the development of methods and tools for EMF digital simulation is needed to ensure the electromagnetic safety of the service personnel. Computer models designed to adequately determine the EMF generated by overhead power lines (OPL) can be implemented based on the methods and tools created to determine operating parameters of electric power systems in phase coordinates developed at Irkutsk State Transport University. The technique of electromagnetic safety analysis is implemented based on the proposed approach and has the following features: a systems approach, which is the possibility of simulating electromagnetic fields in terms of properties and characteristics of a complex electric power system; versatility, which allows simulating power lines and traction networks of various designs; appropriateness to the environment achieved by considering the profile of the underlying surface, underground utilities, and artificial structures of rail transport, such as galleries, bridges, and tunnels; comprehensiveness, which is provided by combining the computation of operating parameters and the determination of EMF intensities. The paper describes methods and algorithms developed to determine the intensities of electromagnetic fields generated by multi-conductor power lines at fundamental and higher harmonics frequencies. A technique for the EMF determination at the points of OPL orthogonal crossing is also presented.

Full textAbstract:
This work considers an emerging value-based paradigm for solar generation under high penetration, in light of its conflicting cycles of supply and demand. The resulting swings in electricity prices, in locales such as California, call into question the aim of optimizing solar arrays solely in terms of accumulated electrical power. Thus, this work studies solar arrays in terms of value, as an accumulated product of electrical power and price, where solar arrays that generate greater electrical power over more profitable early- and late-day hours yield improved value. Experimental, theoretical, and economic analyses are given to characterize the industry-standard angled-panel, an alternative V-groove, and a new U-groove array over a 5-year study. The trends and projections suggest that the industry-standard angled-panel array realizes the best value-based performance at present, although it will likely be outperformed in the foreseeable future by the V-groove array.

Full textAbstract:
This work discusses the implementation of a Unique Ships Grid design that utilizes Energy Storage. This Unique Ships Grid is used to enhance the efficiency of a Construction Single-Hull River Tender previously discussed and assessed by the Army Corps of Engineers and the United States Coast Guard (USCG). This Grid Design is shown to be both in compliance with applicable regulations and reliable due to built-in redundancy. Compliance with regulations and redundancy are both prized by the Maritime Community and the USCG. An applicable Heuristic Design Methodology is provided in conjunction with the Unique Ships Grid. This Design Methodology can be used with a simple load analysis and results in a Load Center breakdown and the sizing of Cables, Generators, Inverter, and required Energy Storage. This design process is shown to provide an inherent margin for growth and safety. This design process is quick and results in values necessary to do a cost analysis, environmental impact survey, and stability analysis (Ship Stability not Electrical Stability).Master of Science

[EN] Abstract
This research arises under the the PhD in Arts: Production, Management and Restoration (Mexico), taught by the Polytechnic University of Valencia, Spain. The principal hypothesis is: The visual dimension of a city is the result of an ideological process and its enunciation in speeches and works emerged within the ruling classes. Modern societies and their space par excellence, the cities, are constructed and deconstructed in terms of assimilation or resistance of this symbolic speech; always contextualized to the socio-historical circumstances of its time.
Consistent with this spatiotemporal specificity, Mexico City, the Federal District, is the place to study. The particular case of study is the billboard; leading visual support in postmodern. The monumental advertisement is the unequivocal symptom of the commodification of our time, a result of rise of the cultural industry and its control strategies of social behavior, through its rhetorical tactic and thanks to its enunciative instrument: publicity. The excessive proliferation of these supports irreversibly affect the urban landscape and the identity of the urban planning manner, but inexorably, also the ways of being and doing of the inhabitants of those asphalt and concrete's places.
To achieve this end, we start from the substantiation of a statement reasoned here: Art is the ideological artifact of its time; a human manifestation of dialectical responding to the historical and social circumstances of its time; so, then the art produced today is one that must be understood as a correlate of the cultural industry and the consumer society.
Methodologies employed: From the methodological framework of depth hermeneutics , are developed socio-historical studies of contemporary artistic and symbolic forms of the billboard; considering the contributions of the sociologist John B. Thompson and semiotics from Charles S. Peirce's and George Peninou. In particular, the subject is treated the particular cases of visual artists, who has operated billboards from the meanings that arise in the dichotomy Cultural Art-Industry, focusing on its dialectical tension in the urban environment of Mexico D.F. by registering and cataloging examples of these supports in arteries of this capital.

Teniendo por hipótesis principal la siguiente: La dimensión visual de una ciudad es resultado de un proceso ideológico y de su enunciación en los discursos y obras surgidas del seno de las clases dominantes. Las sociedades modernas, y sus espacios por antonomasia: las ciudades, se construyen y deconstruyen, en términos de asimilación o resistencia de éste discurso simbólico contextualizado por las circunstancias socio-históricas de su tiempo. Congruentes a esta especificidad espacio-temporal, el lugar a estudiar es la Ciudad de México Distrito Federal. El estudio de caso particular es la valla publicitaria. Soporte visual protagónico de las urbes posmodernas. El anuncio publicitario monumental, es síntoma inequívoco de la mercantilización de nuestra época, resultado del encumbramiento de la industria cultural y de sus estrategias de control del comportamiento social, a través de su táctica retórica y gracias a su instrumento enunciativo: la publicidad. La proliferación desmedida de estos soportes, afecta de manera irreversible al paisaje urbano y a la identidad de la planificación urbana, pero también, los modos de ser y hacer del habitante de estos espacios de asfalto y cemento. Para lograr tal fin, partimos de la comprobación de una afirmación aquí argumentada: El arte es artefacto ideológico de su época. Una manifestación humana que responde de manera dialéctica a las circunstancias históricas y sociales de su contexto.

Full textAbstract:
This chapter examines the shifting dynamics of the magazine producer–consumer relationship within two different industrial contexts. First, it considers how media producers are making their offerings for audiences more interactive by integrating commentary, advice, photos, and more. It situates this trend in historical perspective by recalling women's magazines' tradition of “inviting readers in.” Second, it looks at an external force encroaching on magazine production: the rise of fashion blogging. It also describes the labor politics of user-generated content and goes on to discuss how various industry insiders conceptualize fashion blogging, along with industrial and organizational trends that seem to respond to this cultural movement. The chapter shows that media producers are “inviting audiences in” to numerous spaces that they have carved out within magazine-branded properties. Community chat rooms, virtual programs, and user-generated contests engage interactive consumers while supplanting the work of professional content producers. Although editors of women's magazines maintain control over these initiatives, they have unequivocally less power over fashion bloggers.

Full textAbstract:
AbstractNew employment demands of a burgeoning Indian software service industry are spawning neo-educational structures, especially in the domain of data sciences through vibrant market mechanisms offering a scalable and industry-focused learning system. Since the 1990s, Indian software firms have developed expertise in carrying out outsourced back-office tasks and mid-level IT services like data entry, managing call centres, and performing software quality testing for foreign companies taking advantage of a technically trained local workforce. The trend of automating manual work practices in the IT industry has generated a different kind of demand for data sciences directed at upskilling and job readiness. India is witnessing a market-oriented groundswell of data science and IT skill tutoring ‘shops’, resituating science and engineering education. In this chapter we report from ethnographic research conducted in two IT skill training parks to underpin arguments about emerging neo-educational learning structures suited to a data science education for new livelihood opportunities in an IT-accredited India. Our chapter makes a case for looking at ‘data studies’ from an ethnographic perspective uncovering a ‘program’ of upward mobility through IT skilling and employment. What directions might data studies about tutoring data science skills in the Indian context lead to? Excerpts presented here from field research imagine new livelihoods, aspirations, and technology skills that are more often than not a reflection of the power of data science education.

Telecommunications industry requires efficient, reliable and cost-effective hybrid power system as alternative to the power supplied by diesel generator. This paper proposed an operational control algorithm that will be used to control and supervise the operations of PV/Wind-Diesel hybrid power generation system for GSM base station sites. The control algorithm was developed in such a way that it coordinates when power should be generated by renewable energy (PV panels and Wind turbine) and when it should be generated by diesel generator and is intended to maximize the use of renewable system while limiting the use of diesel generator. Diesel generator is allocated only when the demand cannot be met by the renewable energy sources including battery bank. The developed algorithm was used to study the operations of the hybrid PV/Wind-Diesel energy system. The control simulation shows that the developed algorithm reduces the operational hours of the diesel generator thereby reducing the running cost of the hybrid energy system as well as the pollutant emissions. With the data collected from the site, a detailed economic and environmental analysis was carried out using micro power optimization software homer. The study evaluates savings associated with conversion of the diesel powered system to a PV/Wind-Diesel hybrid power system.

This concluding chapter presents a reading of “Good Bye, Big Sky” and “The Giant Revived,” two articles on coal's rise as the fuel of postwar America and the cost of that transition. “The Giant Revived” explained how American electrical utilities found coal to be an inexpensive alternative to natural gas and nuclear power that could meet the nation's burgeoning demand for electricity. This demand drove a revival of the coal industry. By 1970, demand from utilities had tripled the amount of electricity generated by coal since 1956. Meanwhile, “Good Bye, Big Sky” suggested the costs of coal's new place as the nation's dominant source of electricity. With Four Corners alone releasing approximately 46,000 tons of nitrogen oxide and 35,000 tons of sulfur dioxide—the two main chemical components of smog—as well as 50,000 tons of fly ash annually, the resulting air pollution obscured vistas and suggested the Southwest's unique nature had come to an end.

Full textAbstract:
Bulk power system based on fossil fuels becomes less reliable and stable in economic terms, technically more labor-consuming and harmful environmental impact. These problems have led many countries to find ways to supply the electricity from a green and sustainable energy source. The electricity derived from renewable energy sources such as hydro, solar, wind, biomass and geothermal refers to as green and sustainable energy. Geothermal energy is not only utilized for electric power generation, but it is also exploited to generate environmentally friendly heat energy. As of the end of 2018, geothermal global cumulative installed capacity exceeded 13 GW, generated an energy of about 630 peta joule (PJ). This chapter presents the geothermal energy resource in terms of the types of power plants, principle of the electricity generation and current world status of geothermal resource utilization. The issues such as advantages and disadvantages of geothermal energy economically and environmentally and means to overcome shortcomings are also considered. The main barriers for the development of geothermal industry include high resource and exploration risk, overall high development cost particularly drilling, and inadequate financing and grant support. The global averaged cost of electricity for the geothermal facility is nearly 0.072 USD/kWh as compared to 0.056 for onshore wind and 0.047 USD/kWh for hydropower. However, the technology is rather competitive to other renewables such as concentrating solar power (0.185 USD/kWh) and offshore wind (0.127 USD/kWh). Meanwhile, further research and development is critically needed to eliminate the non-condensable gases (NCGs) associated with the geothermal power generation.

The advent of new technologies has brought forth an incredible power to online users of social media who may act as active contributors and co-creators of the tourism communication and promotion of the areas that have visited, influencing in that way the online image that is created for an area, a region or a country. The user-generated content (UGC) that is created and uploaded, text and/or travel photos allows research to examine tourists' behavior. How can this be depicted with the use of photos taken from visitors for a rural area? The present chapter aims to (a) examine the destination image of Brasov County's (Romania) based on UGC created via photos uploaded on Facebook by a selected group of visitors in the area; (b) to examine the projected image and strategy in official Brasov County's websites and strategic documents and (c) to create a set of recommendations for the promotion of the Brasov County's rural area on the international tourism market.

Full textAbstract:
This report presents a validation of the design and operation of an accelerated testing facility for the study of foreign deposit layers typical to the operation of land-based gas turbines. This facility was designed to produce turbine deposits in a 4-hour test that would simulate 10,000 hours of turbine operation. This is accomplished by matching the net foreign particulate throughput of an actual gas turbine. Flow Mach number, temperature and particulate impingement angle are also matched. Validation tests were conducted to model the ingestion of foreign particulate typically found in the urban environment. The majority of this particulate is ceramic in nature and smaller than 10 microns in size, but varies up to 80 microns. Deposits were formed for flow Mach number and temperature of 0.4 and 1150degC respectively, using air plasma sprayed (APS) TBC material coupons donated from industry. Investigations over a range of impingement angles yielded samples with deposit thicknesses from 20 to 100 microns in 4-hour, accelerated-service simulations. Above a threshold temperature, deposit thickness was dependent on impingement angle and particle concentration. Test validation was achieved using direct comparison with deposits from service hardware. Deposit characteristics affecting blade heat transfer via convection and conduction were assessed. Surface topography analysis indicated that the surface structure of the generated deposits were similar to those found on actual turbine blades. Scanning electron microscope (SEM) and x-ray spectroscopy analyses indicated that the deposit microstructures and chemical compositions were comparable to turbine blade deposit samples obtained from industry.

Full textAbstract:
Abstract In the current energy industry, there is a strong emphasis on environmental, social, and governance (ESG). Specifically, managing the flaring of natural gas. Globally, 142 bcm of natural gas was flared in 2020. This resulted in around 265 Mt CO2, nearly 8 Mt of methane, and other GHGs being directly emitted into the atmosphere (Schulz, 2021). We have a focus of eliminating the emissions surrounding flare gas by utilizing the EPA’s Avoided Emissions and geneRation Tool. The technology does this by utilizing a waste gas stream that would otherwise be combusted or flared and turn it into useable grid power. The waste gas stream is collected from the well and production equipment, then combusted in a natural gas generator. Power from the generator is converted to DC power, sent to a small capacitive bank, electronically synced, and sold back to the power grid using a 208 or 480v 3 phase connection. All applicable operational data is collected via sensors (power, pressures, errors, flow), stored in a database, and visualized through a website. This paper presents and discusses a case study of using this waste gas stream technology to not only generate electricity but significantly decrease the emissions into the atmosphere through the EPAs avoided emissions tool. The first step involves identifying the appropriate pad site with stranded or flare gas volumes of at least 50 mcfd. Once a site is identified, the next step involves determining what the electrical infrastructure on location comprises and if it has 480v 3-phase power. With the location identified it is time to bring the unit on site. The unit is comprised of a natural gas generator skid and the patented technology skid. We installed a VRU and tied directly into the flare line and through a scrubber to the generator. The next step is to move the power to the proprietary technology skid unit and clean the DC power to grid acceptable AC power. We then moved the clean AC power to run the production equipment on site and the balance onto the power grid. On our case study test site, we captured 1.4 mmcf that would have otherwise been leaked into the atmosphere and generated approximately 80 MW that was sold back to the grid. The technology presented in this paper reduced GHG emissions, provided a power source on location, and generated revenue for the operator. Our case study application would reduce GHG emission by approximately 3,400 lbs. in a one-year timeframe. The result of this technology is a new and novel technique for the energy industry to use to decrease emissions, generate onsite power, and generate revenue from selling power back onto the grid.

Full textAbstract:
For more than 60 years now, the nuclear power industry has relied on structural and pressure retaining materials generated via established manufacturing practices such as casting, plate rolling-and-welding, forging, drawing, and/or extrusion. During the past three years, EPRI has been leading the development and introduction of another established process, powder metallurgy and hot isostatic pressing (PM/HIP), for pressure retaining applications in the electric power industry. The research includes assessment of two primary alloys: 316L stainless steel and Grade 91 creep-strength enhanced ferritic steels, for introduction into the ASME Boiler and Pressure Vessel Code. Continuing DOE and EPRI research on other structural/pressure retaining alloys such as Alloy 690, SA 508 Class 1, Alloy 625, hard-facing materials, and others are also underway. This research will have a tremendous impact as we move forward over the next few decades on the selection of new alloys and components for advanced light water reactors and small modular reactors. Furthermore, fabrication of high alloy materials/components may require the use of new manufacturing processes to achieve acceptable properties for higher temperature applications such as those in Generation IV applications. Current research by EPRI and DOE will be reviewed and emphasis will be targeted at advanced applications where PM/HIP may be applied in the future.

Full textAbstract:
Abstract The calculation of acoustic induced vibration (AIV) for piping downstream of a valve is a critical step in predicting the damage from extreme levels of noise generated by pressure relief valves in flare systems. Three noise prediction schemes are considered for this purpose: International Electrotechnical Commission (IEC) 60534-8-3, the Carucci-Mueller (C-M) formulation for sound power, and an industry valve noise prediction methodology published in the 1980’s. The application of these prediction methods is reviewed utilizing data from a full-scale test system consisting of an NPS6x8 pressure relief valve flowing into a NPS12 tailpipe that is connected through a tee to an NPS20 header. The results show good correlation between the IEC-based predictions and measured internal sound pressure and pipe wall vibration in the AIV frequency region. The industry method provides useful predictions without requiring the level of detailed information needed for the IEC method, whilst the C-M sound power model has limitations when applied to discrete predictions of vibration and strain levels. Observations are also made regarding the relative importance of the FIV contribution to the overall dynamic stresses and associated fatigue life.

Currently, nuclear power plays a quite visible role in the world electricity generation (∼11%). However, before the Fukushima Nuclear Power Plant (NPP) severe accident in March of 2011, NPPs generated about 14% of the world’s electricity. Accounting that after, mainly, Chernobyl NPP severe accident a number of power reactors built and put into operation in the world decreased from 120 within 1985–1990 to about 22 per 5 years (within 1995–2015), we might face a significant shortage of operating power reactors within 2030–2040. Therefore, it is important to evaluate current status of nuclear-power industry and to make projections on near (5–10 years) and far away (10–25 years and beyond) future trends in nuclear-power industry. In the current paper statistics on all current nuclear-power reactors were analyzed and based on that future trends were estimated in terms of types of reactors to be left after 10 years, new types of reactors to be put into operation, projections of how many reactors and of which types will be build. To make any projections an average operating term of power reactors should be estimated. In the current paper a nuclear-power-reactor operating term of 45 years was considered. Also, rates of building and putting into operation power reactors worldwide were estimated, and several scenarios of future developments in nuclear-power industry in the world and in selected countries were considered.

Full textAbstract:
Abstract Electrical power, generated and consumed, is perhaps, one of today’s most important construct in determining the progress of a people. The power mismatch between the generated and consumed power is one of the major issues faced in the electricity industry. This can be addressed by analysing user behaviour and manipulating it. This paper attempts to put forth a demand response (DR) technique using the concept of Time-of-Use (ToU) electricity pricing. The utilities have an upper hand of quoting the electricity price whereas the users must follow this price and give their best response of power consumption. This process is similar to a leader-follower setting as in a Stackelberg game where the follower acts according to the leader’s strategy and gives its best response in every situation. This paper proposes a pricing technique where the users are charged according to the amount of power consumed in the specific period of time.

Full textAbstract:
The objective of this work is to develop an interactive computer aided preliminary design program for shell and tube heat exchanger based on the Bell (Delaware) method with internal evaluation of all required physical properties utilizing the best methods in the open literature known for their accuracy and reliability. FORTRAN90 is the program language used in this work. All mechanical and geometrical required data are internally evaluated. This program will be used to study the performance of Bell (Delaware) method by comparing the results obtained via this program with experimental data from industry. Cost estimates are to be generated by the program for all components, using very well known cost estimate techniques. Finally, the developed program was tested for accuracy and consistency against existing design cases from industry. The program was tested with other six experimental samples, and it was found that the program work accurately and the percentage of error in most parameters are in the allowable.

Full textAbstract:
The electric power generated in a steam-power plant depends on condenser pressure. Plant performance personnel are frequently called upon to predict effects on megawatts generated and plant heat rate as condenser circumstances vary. The flow rate of circulating water to the condenser is one of the factors that impact the results when doing such predictions. This paper utilizes the PEPSE modeling program to evaluate the effect on the condenser back-pressure and power generation of plugging condenser tubes. The circulating water flow rate is the focal point of this analysis because it influences the heat transfer coefficient inside of the tubes of the condenser. This inside-tube convection heat transfer coefficient is an important contributor to the calculated overall condensing heat transfer coefficient and the resulting condenser pressure. Calculation of the condenser’s shell side pressure is based on the Heat Exchange Institute’s (HEI) methods that are standard in the industry. In operation the circulating water’s flow rate occurs at the point where the head of the circulating water pump balances the hydraulic pressure drops in the circuit. Equations are presented to account for circulating water pressure drops, as foundation for calculations of the hydraulic balancing. The equation methodology is then applied to an actual condenser design.
