This study advances several methods to evaluate the operation of a hydrogen generator plant. The model developed helps customize plants that contain multiple generators of varying powers using a decision module, which determines the most efficient plant load distribution. Evaluation indices to assess individual devices within the plant are proposed and system flexibility maximizes the amount of renewable energy stored. Three case studies examined the variable load distribution of an electrolysis system connected to a 40 MW wind farm for energy storage purposes and incorporated a “night-valley” operational strategy. These methods facilitate the selection of the proper plant configuration and provide estimates for individual device effectiveness within the system. more...

One of the important aspects of realizing smart cities is developing smart homes/buildings and, from the energy perspective, designing and implementing an efficient smart home area energy management system (HAEMS) is vital. To be effective, the HAEMS should include various electrical appliances as well as local distributed/renewable energy resources and energy storage systems, with the whole system as a microgrid. However, the collecting and processing of the data associated with these appliances/resources are challenging in terms of the required sensors/communication infrastructure and computational burden. Thanks to the internet-of-things and cloud computing technologies, the physical requirements for handling the data have been provided, however, they demand suitable optimization/management schemes. In this article, a HAEMS is developed using cloud services to increase the accuracy and speed of the data processing. A management protocol is proposed that provides an optimal schedule for a day-ahead operation of the electrical equipment of smart residential homes under welfare indicators. The proposed system comprises three layers: (1) sensors associated with the home appliances and generation/storage units, (2) local fog nodes, and (3) a cloud where the information is processed bilaterally with HAEMS and the hourly optimal operation of appliances/generation/storage units is planned. The neural network and genetic algorithm (GA) are used as part of the HAEMS program. The neural network is used to predict the amount of workload corresponding to users’ requests. Improving the load factor and the economic efficiency are considered as the objective function that is optimized using GA. Numerical studies are performed in the MATLAB platform and the results are compared with a conventional method. more...

Zonal express is an operational strategy for express transit service that only stops in the initial and final zones of its route while skipping stops in-between. Zonal express provides a service with less travel and transfer time by aggregating trip demands with similar origins, destinations, and departure times. In this study, new zonal express routes are designed to reduce the travel and transfer times of transit users efficiently. This study develops a methodology that considers demand diversion. To meet the purpose, the following are conducted: (1) estimation of zonal express demand; (2) clustering of demand with similar origins, destinations, and departure times; (3) selection of candidate clusters; (4) optimization of stops and routes of zonal express; and (5) determining zonal express routes in which the benefit from reduced time and transfers outweighs the cost. The methodology is applied to an actual transportation network in Seoul, South Korea, using smartcard, car navigation, and spatial information data. The result shows that zonal express can reduce users’ travel time and the number of transfers effectively. This study proposes that it is desirable to introduce the zonal express sequentially from the route with the highest net benefit under a budget constraint. This study also presents the results when fares change to provide implications for pricing strategies of the zonal express. Future studies can consider incorporating various objective functions or utilizing vehicles in different time slots. more...

In Project WASTEC, an experimental Reverse Osmosis (RO) desalination system was developed. It serves as a platform for testing new technologies. For this system, we solved two problems, which are described in this paper. Firstly, we developed and investigated strategies for scheduling chemical enhanced backwashing and chemical cleaning and secondly, due to the experimental nature of the project, several new technological developments with respect to materials and methods were integrated into the system and requires tools for evaluating the economic viability of the new technologies. In this task, the economics of membrane-based desalination will be investigated. Baseline systems of reverse osmosis and pretreatment systems (microfiltration and ultrafiltration) will be economically examined and compared for their investments and operational costs. Sensitivity of the different plant and membrane parameters to the cost will be studied. Results show that with respect to costs, for a 200m3/hr design capacity plant, a volume of water is produced by a MF process at a cost of $0.494 and at a cost of $0.486 by an ultrafiltration process microfiltration. The reverse osmosis process cannot be compared directly, but it required $ 0.49 / m3 for a plant with 56 m3/hour design capacity. The values are in line with the costs reported in literature for membrane-based filtration. more...

In conditions of uncertainty, an enterprise should have a rational basis for making decisions, which would enable the comparison of different alternatives and the choice of the most suitable action for achieving its objectives. Some researchers consider that uncertainty is generated either by insufficient knowledge about the nature of phenomena and processes or by the lack of information about these phenomena and processes. The author considers that these interpretations need to be completed by clarifying the motives which cause uncertainty. The following types of environment can be distinguished which could be considered as sources of uncertainty: socio-economic; scientific and technical; political and juridical; the sales partners’ environment; the environment of the seller; the competitors’ environment; the consumers’ environment; the investments environment. The aim of the present paper is to determine the degree of influence (markedness) of each type of uncertainty upon the decisions made while selecting the operational strategy by the industrial enterprise. The research has been carried out at 29 enterprises from different industrial fields from Romania: metallurgical industry, production of basic pharmaceuticals and pharmaceutical preparations, construction materials industry, food-processing industry, manufacture of chemical substances and products. The management teams of those companies have taken part in the survey. The research is based on the data processing and analysis obtained from 256 questionnaires. The survey carried out within the industrial enterprises has shown that the uncertainty from the consumption environment has the biggest impact upon the operational decisions of the companies. The uncertainty from the internal, political, juridical, scientific and technical environment is being analyzed to a lesser extent. The lowest domain of uncertainty is characteristic for the chemical industry and the highest for the industry of manufacture of basic pharmaceuticals and pharmaceutical preparations. more...

Three-phase unbalanced conditions in distribution networks are conventionally caused by load imbalance, asymmetrical fault conditions of transformers and impedances of three phases. The uneven integration of single-phase distributed generation (DG) worsens the imbalance situation. These unbalanced conditions result in financial losses, inefficient utilisation of assets and security risks to the network infrastructure. In this study, a phase-changing soft open point (PC-SOP) is proposed as a new way of connecting soft open points (SOPs) to balance the power flows among three phases by controlling active power and reactive power. Then an operational strategy based on PC-SOPs is presented for three-phase four-wire unbalanced systems. By optimising the regulation of SOPs, optimal energy storage systems dispatch and DG curtailment, the proposed strategy can reduce power losses and three-phase imbalance. Second-order cone programming (SOCP) relaxation is utilised to convert the original non-convex and non-linear model into an SOCP model which can be solved efficiently by commercial solvers. Case studies are conducted on a modified IEEE 34-node three-phase four-wire system and the IEEE 123-node test feeder to verify the effectiveness, efficiency and scalability of the proposed PC-SOP concept and its operational strategy. more...

Solar thermochemical water splitting was successfully demonstrated with monolithic receiver-reactors in field at 50 kW scale. Since monolithic receiver-reactors are limited in size, several of the reactors will have to be combined in receiver-reactor arrays for large-scale plants. In this study, the yearly performance of solar thermochemical plants for hydrogen production implementing receiver-reactor arrays is investigated. Thereto, a transient receiver-reactor model is used in combination with realistic hourly flux profiles from dedicated MW high temperature solar concentrator systems. The batched operation of receiver-reactors leads to particular requirements of the array. Therefore, an array efficiency is introduced and different control strategies for the solar field are analyzed for performance optimization. Advanced strategies have the potential to substantially (~46%) improve the overall performance compared to the base case. Further design and operational optimization approaches are discussed, which allow approaching the theoretical array performance limit. more...

Lithium metal, although attracting renewed interest for the next revolution in energy storage, continues to be challenged with the detrimental dendrite formation. Recent experimental reports have demonstrated the contrasting impact of thermal attributes on the electrodeposition morphology, showcasing the alleviation and/or aggravation of dendrite formation. Herein, we present a comprehensive discourse to discern the thermally activated physical mechanisms governing lithium electrodeposition morphology. We report that the synergistic effect of enhanced electrolyte transport and surface self-diffusion under a uniform thermal field (∼75 °C) enables adequate dendrite suppression, even at high reaction rates. However, in contrast to this, a localization of the thermal field substantially increases the exchange current density of the confined region, instigating the growth of needle dendrites. Based on our mesoscale analysis, we demarcate safety limits for such an event, beyond which dendrite growth is inevitably triggered. Therefore, though the operational strategy of elevating the cell temperature promises to resolve the challenge of stable electrodeposition, it comes along with the caveat. This fundamental study provides a detailed insight into underlying electrochemical-thermal complexations, critical to the performance and safety of metal-based rechargeable batteries. more...

PurposeThis paper has a twofold purpose: (1) to demonstrate, largely with historical evidence, that, contrary to what some have argued, thinking about educational research articulated at the start of the twenty-first century was not really “new wine in new bottles” but, rather, a continuation of the so-called paradigm wars about, ultimately, unresolvable methodological and epistemological issues that occurred during the twentieth century; (2) to suggest a way members of the educational administration field might transcend, or at least circumvent, time-consuming and distracting battles about unresolvable methodological and epistemological issues in the future while keeping their focus on issues of practice.Design/methodology/approachThis is a quasi-historical essay that uses influential literature during the historical periods focused on as evidence to support the essay's arguments.FindingsThe paper demonstrates that twentieth century philosophical disagreements about research methods and the role that educational research can play in policy and practice decision making were not resolved but, rather, were largely reenacted during the first decade of the twenty-first century, again without a resolution. The paper proposes a way that administrators, policymakers and researchers can manage this situation and still use research to make policy and practice decisions.Practical implicationsThe paper suggests a new role for both school administrators and policymakers to play. If administrators/policymakers play this role successfully, all types of research can inform decision making about policy and practice, and researchers can concentrate on doing their research rather than engaging in unresolvable philosophical disputes.Originality/valueAlthough a great deal has been written about the twentieth century's theory movement and paradigm wars and the twenty-first century's so-called science wars, the link between these phenomena has not been discussed in the literature. In addition, there have been few attempts to articulate an operational strategy for managing unresolvable philosophical disputes about research methods and the role that research can play in decision making. This paper tackles both matters. more...

This work presents theoretical evidence that the vacuferm technology can confer several advantages even when the fermentor is operated in fed-batch mode with small cycle times aiming to avoid the accumulation of potentially inhibitory side products. More specifically, a mathematical model for a fed-batch fermentor coupled with a vacuum flash tank for in situ ethanol recovery is developed and the simplest possible operational strategy is optimized within the context of maximizing the volumetric productivity of the process. Using numerical values obtained from the literature, it is demonstrated that significant increase in the volumetric productivity of ethanol (up to 33.5 kg EtOH m−3 h−1) can be achieved. Evidently, the results obtained indicate the potential to employ the proposed methodology to operate existing industrial facilities with minor modifications and equipment additions. more...

Innovation is critical to a firm’s success in the current world. Several key features play important roles in the innovation process, including the innovation level, innovation uncertainty and new product press timing. This paper develops a framework where a high-tech firm sequentially introduces new products with incremental innovation over two selling seasons in the presence of strategic consumers and uncertain demand, to address the firm’s optimal stocking and pricing decisions, and investigate how the key innovation features impact the firm’s operational strategy and profit. By characterizing the subgame perfect Nash equilibrium with rational expectations, we find: (1) Strategic consumers can increase the firm’s profit when demand variance is high, for the successive innovation allows the firm to take advantage of consumers’ deferred purchase to better match supply and demand. (2) The firm’s total expected profit always decreases with respect to the new product press time under certain mild condition, but can be non-monotonic with respect to the RD high innovation level can play a role as price commitment when it exceeds one threshold. more...

The different oxygen affinities of ammonia-oxidizing (AOB) and nitrite-oxidizing bacteria (NOB) are often used to define the operational strategy to achieve partial nitritation (PN) required before the anammox (AMX) process. For this purpose, apparent kinetic parameters are mainly used in the case of granular sludge, which can lead to errors when defining the operational conditions to obtain only nitritation (avoiding nitratation). In the present study, a mathematical methodology is proposed to determine the intrinsic kinetic parameters of AOB and NOB in granular sludge based on data obtained by respirometric assays. Additionally, the oxygen affinity constant (KO2) and maximum specific rate (rmax) of flocculent and granular sludge sample, produced under mainstream and sidestream conditions were determined at various temperatures (15, 20 and 30 °C). The results show that for granules, the intrinsic KO2 and rmax values were lower and higher, respectively, than the apparent values. Furthermore, the KO2 values for flocs and granules at all of the tested temperatures were lower for NOB than for AOB. The values obtained for the kinetic parameters indicated that it is impossible to maintain partial nitritation by only controlling the dissolved oxygen concentration. more...

Program penyuksesan pencapaian prioritas pembangunan kesehatan tahun 2015-2019 melalui program Indonesia Sehat, pemerintah mengerahkan segala upaya dan segenap potensi yang ada baik dari pemerintah pusat, Provinsi, Kabupaten/Kota, maupun masyarakat. Dalam pelaksanaannya, pembangunan kesehatan dimulai dari unit terkecil dari masyarakat, yaitu keluarga. Hal tersebut dikarenakan upaya mewujudkan keluarga sehat menjadi titik awal terwujudnya masyarakat sehat. Oleh karena itu Kementerian Kesehatan menetapkan strategi operasional pembangunan kesehatan melalui Program Indonesia Sehat dengan Pendekatan Keluarga dengan 12 indikator. Salah satunya adalah keluarga mempunyai akses atau menggunakan jamban sehat. Salah satu Kabupaten yang menjadi perhatian Dinas Kesehatan Provinsi Sumatera Barat adalah Kabupaten Solok dimana hanya 48,57% keluarga yang mempunyai akses atau menggunakan jamban sehat. Angka ini di bawah target Indikator Indonesia Sehat. Untuk itu, melalui kegiatan Pengalaman Belajar Lapangan (PBL), diupayakan peningkatan akses terhadap jamban sehat melalui penyuluhan (metode ceramah) dan pemicuan jamban sehat, pembagian leaflet, dan pemasangan stiker pada rumah yang telah menggunakan jamban sehat. Dari kegiatan ini disimpulkan bahwa intervensi berjalan dengan baik dan semua indikator tercapai walaupun terdapat penolakan dari beberapa masyarakat. Disarankan puskesmas meningkatkan kerja sama dengan berbagai pihak untuk dapat membantu masyarakat dalam membangun jamban yang lebih layak. more...

The operation strategies of a distributed energy system (DES) are usually proposed according to the electrical load (FEL) and the thermal load (FTL), which take the cooling/heating load or electric load as unique constraint conditions that result in a too high or too low equipment load rate. This paper proposes a new hybrid operation strategy (HOS) that takes the full utilization of natural gas and the minimization of power consumption from the power grid as constraints and coordinates the cooling/electricity ratio and heating/electricity ratio of buildings and equipment. In the optimization phase of a DES, an optimization method based on the discretization of the load is proposed to investigate the influence of the uncertainty of the load on the DES, which helps to avoid repeated load simulations and provides stronger adjustability by quoting the normal distribution function to obtain multiple sets of load data with different fluctuations. Further, a multi-objective optimization model combining the genetic algorithm (GA) and mixed integer linear programming algorithm (MILP) was established to find the optimal configuration of equipment capacities by comprehensively considering the annual total cost, carbon emissions, and energy efficiency of the DES. Finally, an office building example was used to validate the feasibility of the above theories and methods. Compared with the FEL and FTL, the HOS reduced the energy waste of the DES by 19.7% and 15.5%, respectively. Compared with using a typical daily load, using an annual hourly load to optimize the DES-HOS produced a better comprehensive performance and lower adverse impacts derived from load fluctuations. more...

Rising dissolved organic carbon (DOC) is interfering with drinking water production. While strategies for DOC removal during water treatment have been successfully implemented, the potential for DOC load reduction by optimized reservoir operation is not yet fully explored, mainly constrained by data paucity on real-time DOC dynamics. In this study, we utilized the emerging in situ high-frequency (HF) monitoring technique for DOC and developed a simulation–operation framework that promotes DOC mitigation in Germany’s largest drinking water reservoir. Rappbode Reservoir is embedded in a network of smaller upstream reservoirs from which Königshütte Reservoir delivers the most water but can also be operated as a bypass system. Using high-frequency monitoring of DOC concentrations and discharge at the inflows and outflows, we constructed a mass balance model that simulated the DOC dynamics in the reservoir, allowing us to explore alternative operation regimes that deliver the same amount of water but a lower DOC load. Our results show that, through rapid decision-making that enables bypassing of water with high DOC concentrations around the drinking water reservoir, the optimized operation regime is able to reduce DOC load of the drinking water reservoir by 25 ± 3%. Therefore, our proposed operational strategy to minimize DOC loading to reservoirs is promising. more...

Up to the early 2000s, artificial intelligence (AI) was perceived as a utopia outside of the restricted AI research and development community. A reputation that AI owed to its relatively poor performance at the time. In the early 2000s, significant progress had been made in the design and development of microprocessors, leading to computers capable of efficiently executing AI tasks. Additionally, the ubiquity of the Internet had led to data proliferation, characterized by the continuous generation of large volumes of structured and unstructured data at an unprecedented rate. The combination of the increasing computing power and the availability of large data sets stimulated extensive research in the field of AI, which led to successful deployments of the AI technology in various industries. Through such success, AI earned a place in the spotlight, as organizations continue to devote significant effort to integrate it as an integral part of their day-to-day operational strategy. However, the complex nature of AI often introduces challenges that organizations must efficiently address to fully realize the potential of the AI technology. more...

The effects of capacity sizing and operational strategy of the CHP systems were numerically studied for optimal energy management of the CHP-based public building thermal energy network with novel heat trading using local thermal storage system (LTS). The mixed integer linear program (MILP) based model was developed to minimize the total operation cost of the entire buildings energy network at each time step based on the electricity and heat demands for public buildings in the considered energy network. The public building energy network considered in this study consists of three different buildings (hotel, hospital, and public office buildings) with a small individual CHP system for each building, a large central CHP system, and a LTS system connected to each building. The LTS makes it possible for each building consisting the same energy network to trade excess heat among buildings. The economically optimal capacity sizing of the small individual CHPs at each building, the central large CHP, and the LTS were suggested under various operational strategies and various arrangements of the several small CHPs (gas-engine, gas-turbine, and fuel-cell) installed in each building to minimize the operation cost. more...

Purpose Current recommendations for ‘Febrile seizures’ management include emergency first aid and treatment along with intermittent prophylaxis. Evidence of practices, efficacy, side-effects, and complications should lead to refined and rational management strategies. Patients and Methods Study of cases referred and treated at a tertiary level hospital, providing referral services to a large state in India. Evidence sought for the research questions identified, these were (i) immediate treatment: First aid components and practices; response to drug treatment (ii) intermittent prophylaxis: effectiveness, compliance, and side-effects (iii) complications arising due to treatment side-effects: quantifying the number of cases of CNS infections missed as a result of alterations in consciousness levels due to benzodiazepines. Results A total of 85 febrile seizure cases were studied. Full correct “First Aid” was provided by only 13 parents. Total 35 cases (41.18%) had seizures lasting more than 05 minutes. Emergency treatment for these included rectal diazepam in 14 cases with 57.14% success in terminating seizure, and intranasal midazolam in 21 cases with 71.43% success. The cases with persisting seizures were managed as status epilepticus treatment algorithm. Intermittent prophylaxis prevented recurrence of seizures in 90%, however side-effects were reported in 36.36%. There was no case of CNS infection missed. Conclusion Safe and effective management strategy should include “Health education” for correct first aid and ‘Protocols’ for timely and correct emergency treatment by parents/pre-hospital teams/emergency duty doctors. Intermittent prophylaxis is effective but refinements needed to minimize side-effects. Vigilant clinical monitoring obviates the fear that treatment may mask CNS infection., Video abstract Point your SmartPhone at the code above.

Birth of product innovations is a natural phenomenon that takes place as and when the ever-changing consumer needs are addressed. The examples of such innovation technology products are our mobile handsets, the WiFi routers, the microprocessors, the computational devices, and the data storage devices. Such innovations in the products take time to get diffused in the market. While some innovations prove to be successful, some may fail also if either the understanding of the consumer needs is inadequate, or the implementation of the innovation in terms of market entry strategy or operational strategy is faulty. There is plenty of literature on the diffusion modelling of innovations. This review aims to summarize the existing literature on diffusion modelling of innovations and bring about the research gaps that can be addressed in the future. While putting forward the research gaps, the authors attempt to give a due consideration to the contemporary needs of the industry in line with the evolving consumer dynamics and supply dynamics. more...

The paper analyzes some of the problems connected with the design, construction and management of cogeneration plants for district heating networks (CHP-DHN). Although the advantages of cogeneration systems compared with conventional ones for separate energy production, one of the unresolved problems is that of the variability of operating conditions, can often render the application of these solutions ineffective. In particular, the aim of this study is to propose a multi-objective optimization methodology that tries to take into account both energy and economic aspects. After an analysis of the current scenario, the application and use of CHP plants in the international context and the main technological features, followed by the identification of incentive systems that have allowed or limited the spread, attempts are made to define a design methodology based on a multi-level optimum design based approach for increasing the operation share of CHP. The methodology starts from a general system vision, up to detailed aspects such as the management of a CHP-DHN system, taking into account the multiplicity of variables and constraints involved. This methodology has been applied to two case studies representative of the different applications, to verify its robustness and analyze the possible results obtainable. In particular, a general case was taken into consideration, in which a first level design was performed by analyzing various possible system configurations and evaluating their goodness through the tools provided by the aforementioned multi-objective methodology. Then the methodology has been applied to an intermediate level, taking into consideration an existing CHP-DHN plant and going to evaluate the performance considering possible modification of the operation. The results obtained confirm that a combined energetic and economic approach to design allows to obtain an economically feasible system, but at the same time avoids incurring over-sizing, under-sizing or functioning phenomena far from the concept of energy efficiency, difference of what happens for many plants today in operation. Furthermore, through a simple variation of the modularity of the plant, significant benefits can be obtained. more...
