With the advent of ICT in the energy system, new possibilities to inform and influence residential electricity consumption become available. We explore the potential of ICT-based interventions in households to decrease electricity usage, improve energy efficiency and thus contribute to reducing GHG (greenhouse gas) emissions from this sector. Based on a literature review on the subject, we suggest that ICT can affect some of the main behaviour-influencing factors, and discuss the causal avenues by which these effects can take hold. Our review finds that ICT-based effects on consumer behaviour can reduce household final electricity consumption by 0–5%. These and other findings from the literature are used to define parameter values, which reflect the efficacy of ICT at changing household energy usage patterns, and ultimately decreasing GHG emissions from the electricity sector. A quantitative analysis of the potential for ICT to contribute to reaching the 1.5 °C target in the context of the European Union (EU) energy sector is performed. It is found that ICT-based interventions in household energy use could contribute between 0.23% and 3.3% of the EU CO2e reduction target from the energy sector that would keep warming under 1.5 °C, corresponding to 4.5–64.7 mio. tCO2e abated per year.
About 35 % of non-elderly U.S. adult Medicaid enrollees have a behavioral health condition, such as anxiety, mood disorders, substance use disorders, and/or serious mental illness. Individuals with serious mental illness, in particular, have mortality rates that are 2 to 3 times higher as the general population, which are due to multiple factors including inactivity, poor nutrition, and tobacco use. 61 % of Medicaid beneficiaries with behavioral health conditions also have multiple other co-occurring chronic physical health conditions, which further contributes to morbidity and mortality. The Wellness Incentives and Navigation (WIN) project is one of 10 projects under the Centers for Medicare and Medicaid Services “Medicaid Incentives for the Prevention of Chronic Diseases” Initiative, to “test the effectiveness of providing incentives directly to Medicaid beneficiaries of all ages who participate in prevention programs, and change their health risks and outcomes by adopting healthy behaviors.”

Individuals with schizophrenia have been found to display neurocognitive deficits on the order of 1 standard deviation below the mean of healthy controls on a range of cognitive domains, with no clear pattern of deficits that characterizes the majority of individuals with schizophrenia. Such findings have led some to suggest that schizophrenia is characterized by a “generalized” neurocognitive deficit, implying that a common underlying etiology impacts all cognitive domains. Central nervous system accounts of the generalized deficit have been proposed (e.g., NMDA and GABA interneuron receptor dysfunction); however, there may also be more diffuse “general systems” abnormalities that affect brain function. The current study evaluated the role of one type of general systems abnormality, metabolic dysfunction, on global cognitive functioning in a sample of outpatients with schizophrenia (n =27) and demographically matched healthy controls (n =33). Participants completed a battery of neuropsychological tests, as well as metabolic measurements to assess blood glucose, blood pressure, and abdominal obesity. Results indicated that higher pulse pressure predicted the generalized neurocognitive deficit in schizophrenia, but not healthy controls; however, blood glucose and abdominal obesity did not predict cognitive performance in either group. These findings provide support for the role of metabolic abnormalities in the generalized neurocognitive deficit in schizophrenia, and suggest that treatment of hypertension may be a novel adjunctive treatment target for remediating cognitive deficits in schizophrenia.
Valve regulated cells containing lignosulfonates and synthetic organic additives in their negative plates have been evaluated to determine their effect on capacity and cycle life. The negative active material was examined throughout cycle life to determine the effect of the additives on surface area and crystal morphology. Capacity tests were conducted over a range of current densities at ambient temperature and −18°C on cells containing the additives at various levels. All of the materials increased the capacity but considerable differences were observed in the capacity/dosage level responses. All of the organic materials increase the surface area of the active material, and the surface area increases with concentration. The additives produce a morphology composed of small equiaxial grains with high porosity and surface area. During cycling a progressive reduction in surface area takes place which eventually produces a dense structure with low porosity. The capacity and cycle life data show that each additive has a different optimum concentration in the plate. There are also indications that considerably higher concentrations of organic additives can be used in valve regulated batteries than is customarily used in flooded systems.
Two alternative models, including (i) a serial combination of finite-space Warburg (FSW) and finite-length Warburg (FLW) elements, and (ii) two parallel FSW elements with different diffusion time constants, were proposed to describe the most important specific features of potentiostatic intermittent titration (PITT) and electrochemical impedance spectroscopy (EIS) responses of practical intercalation anodes and cathodes. Based on the physical reliability of the fitting parameters, the parallel diffusion path model was seen to describe adequately the EIS and PITT responses obtained from thin, non-uniform composite electrodes (graphite is considered as an example). Some important issues related to impedance modeling (exemplified by comparison of the properties of serial and parallel combinations of distributed diffusion elements) are discussed. We show that dlog|I d (t)|/dlog t vs. t/τ d plots are very useful for diagnosing the type of non-uniformity (particle size distribution, PSD) of intercalation electrodes.
The proposed supervisory control system (SCS) uses a control map to maximize the powertrain efficiency of a hybrid electric vehicle (HEV) in real-time. The paper presents the methodology and structure of the control, including a novel, comprehensive and unified expression for the overall powertrain efficiency that considers the engine-generator set and the battery in depth as well as the power electronics. A control map is then produced with instructions for the optimal power share between the engine branch and battery branch of the vehicle such that the powertrain efficiency is maximized. This map is computed off-line and can thereafter be operated in real-time at very low computational cost. A charge sustaining factor is also developed and introduced to ensure the SCS operates the vehicle within desired SOC bounds. This SCS is then tested and benchmarked against two conventional control strategies in a high-fidelity vehicle model, representing a series HEV. Extensive simulation results are presented for repeated cycles of a diverse range of standard driving cycles, showing significant improvements in fuel economy (up to 20%) and less aggressive use of the battery.
In this work, carbon-coated lithium-ion intercalated compound LiTi2(PO4)3 and MnO2 have been synthesized and they deliver a capacity of 90 and 60mAh/g in 1M Li2SO4 neutral aqueous electrolyte within safe potentials without O2 and H2 evolution, respectively. The novel hybrid supercapacitor in which MnO2 was used as a positive electrode and carbon-coated LiTi2(PO4)3 as a negative electrode was assembled and the LiTi2(PO4)3/MnO2 hybrid supercapacitor showed a sloping voltage profile from 0.7 to 1.9V, at an average voltage near 1.3V, and delivers a capacity of 36mAh/g and an energy density of 47Wh/kg based on the total weight of the active electrode materials. It exhibits a desirable profile and maintains over 80% of its initial energy density after 1000 cycles. The hybrid supercapacitor also exhibit an excellent rate capability, even at a power density of 1000W/kg, it has a specific energy 25Wh/kg compared with 43Wh/kg at the power density about 200W/kg.
Nitrogen-doped carbon materials containing non-precious metal (TM-N-C) and Co-based oxides have been extensively investigated as promising catalysts for oxygen reduction reaction (ORR). Herein, we report a novel Co3O4/Co-N-C modified ketjenblack carbon (KB) catalyst via a one-pot and scalable pyrolysis process using cheap melamine, cobalt acetate tetrahydrate and KB as raw materials. Owing to the high specific surface area and good electrical conductivity, this KB-based catalyst exhibits remarkable catalytic activity with a half-wave potential of 0.798 V (vs RHE) and a limiting current density of 5.10 mA cm−2 in alkaline solution, which are comparable with those of the commercial 20 wt% Pt/C. More importantly, it displays superior stability to Pt/C, which makes it one of the most promising non-noble-metal catalysts. Al-air batteries with this catalyst are also tested and generate a maximum power density of 161.1 mW cm−2, which is close to that with 20 wt% Pt/C catalyst (161.9 mW cm−2). After the discharge for 18 h at 50 mA cm−2, the voltage degradation of Al-air battery with Co3O4/Co-N-C modified KB is 7%, while that using Pt/C is increased to 12%. By virtues of its remarkable performance, low cost and simple fabrication method, Co3O4/Co-N-C modified KB here can be used as an efficient ORR cathode catalyst instead of the commercial Pt/C for practical Al-air batteries.
Industry Life Cycles (ILCs) have been proposed as a means of analyzing the processes of company entry and exit in competitive industries. This paper utilizes ILC approaches to better understand the changing rationales for alliance formation for two large multination electronics firms, Nokia and Ericsson. Through the use of alliance announcements by the firms, we find that the rationale for alliance formation changes over the industry life cycle in response to changing organizational needs and industry imperatives. We also find that the rapid emergence of standards-based alliances has been a strategic response by firms and industries to the growing complexity of information and communication technology systems and the costs involved in ignoring the scale economies that standards-based alliances deliver.
Due to the limited amount of stored battery energy it is necessary to optimally accelerate electric vehicles (EVs), especially in urban driving cycles. Moreover, a quick speed change is also important to minimize the trip time. Conversely, for comfortable driving, the jerk experienced during speed changing must be minimum. This study focuses on finding a comfortable driving strategy for EVs during speed changes by solving a multi-objective optimization problem (MOOP) with various conflicting objectives. Variants of two different competing evolutionary algorithms (EAs), NSGA-II (a non-dominated sorting multi-objective genetic algorithm) and SPEA 2 (strength Pareto evolutionary algorithm), are adopted to solve the problem. The design parameters include the acceleration value(s) with the associated duration(s) and the controller gains. The Pareto-optimal front is obtained by solving the corresponding MOOP. Suitable multi-criterion decision-making techniques are employed to select a preferred solution for practical implementation. After an extensive analysis of EA performance and keeping online implementation in mind, it was observed that NSGA-II with the crowding distance approach was the most suitable. A recently proposed innovization procedure was used to reveal salient properties associated with the obtained trade-off solutions. These solutions were analyzed to study the effectiveness of various parameters influencing comfortable driving.
Nanostructured transition metal chalcogenides (TMCs) have significant interest towards electrochemical devices such as fuel cells, metal-ion batteries, due to their unique physical and electrochemical properties. Herein, we report a facile hydrothermal synthesis of flower-like nanostructured molybdenum sulphide and its incorporation on to graphene as a potential oxygen reduction reaction catalyst in alkaline medium. The phase purity and morphological evolution of MoS2 is systematically studied through X-ray diffraction and scanning electron microscopic techniques. The electronic states of metal and non-metallic species are deeply studied by X-ray photoelectron spectroscopy. The effect of annealing temperatures and TMC concentrations are also investigated by electrochemical techniques such as cyclic and linear sweep voltammograms. The optimised electrocatalyst (MoS2/G-500) delivers significant ORR activity with onset and half-wave potentials of 0.91 and 0.80 V (vs. RHE), respectively. Superior durability compared to state-of-art Pt/C catalyst is ascertained by repeating potential cycles for about 5000 times and also by chronoamperometric technique. Finally, the hybrid catalyst is evaluated in AEMFC as cathode catalyst which delivers peak power density of about 29 mW cm−2 under ambient temperature and pressure. The present findings emphasis that MoS2/G catalyst is promising as cost-effective and alternative to noble metal-based catalysts for fuel cell applications.
Owing to the excellent abundance and availability of sodium reserves, sodium ion batteries (NIBs) show great promise for meeting the material supply and cost demands of large-scale energy storage systems (ESSs) used for the application of renewable energy sources and smart grids. However, the cost advantages of stationary NIBs alone are not enough to ensure their commercial success. In this review, we summarize the emerging attractive characteristics of stationary NIBs, such as high-rate capability, all-climate operation, and full-battery recyclability. Together with inherent cost advantages, these merits have resulted in an excellent compatibility between stationary NIBs and large-scale ESSs that dictates their validity in practical applications. Representative electrode materials are highlighted to illustrate advances in corresponding features. The insights presented in this review can inspire further research interest into NIB design and serve as a guide for the application of NIBs in large-scale stationary energy storage.
The demographic, health and contextual factors associated with quality of life impairment are investigated in older persons from New South Wales, Australia. We examine the impact of cardiovascular and affective conditions on impairment and the potential moderating influence of comorbidity and remoteness.
Electrochemically active CoO/Co3O4 co-existing microspheres with morphology-inherited porous particles is successfully synthesized via a simple solvothermal method. The as-prepared intermixed composite undergoes a monoxide CoO-preferred conversion reaction with an extremely enhanced capacity retention, ∼905 mA h g−1 after 250 cycles for discharge state, which is 1.6 times higher than the conventional CoOx-based anodes. Moreover, stable catalytic behavior of the electrocatalysts in Li-air cathodes of the given composites is also demonstrated. We believe that the extraordinarily enhanced electrode performance might be due to the novel pore-tempered microspheres packed with double electrochemically active centers of the CoO/Co3O4 composite effectively confine the detrimental volume exchange during the reversible cyclic reactions as well as the preserved multiple reactive sites for a reversible Li+ ⇄ LiOx reaction, which is advantageous for advanced Li rechargeable battery.
Biologgers incorporating triaxial magnetometers and accelerometers can record animal movements at infra-second frequencies. Such data allow the Dead-Reckoned (DR) path of an animal to be reconstructed at high resolution. However, poor measures of speed, undocumented movements caused by ocean currents, confounding between movement and gravitational acceleration and measurement error in the sensors, limits the accuracy and precision of DR paths. The conventional method for calculating DR paths attempts to reduce random errors and systematic biases using GPS observations without rigorous statistical justification or quantification of uncertainty in the derived swimming paths.
This study proposes the use of pseudocapacitors obtained from self-assembled materials to harvest energy after complete charge/discharge cycles conducted in electrolytic solutions with different pH values. The negative electrode consisted of phosphomolybdic acid (PMA), poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT-PSS), and polyallylamine (PAH), whereas the positive electrode comprised electrosynthesized PEDOT. The ability of these electrodes to harvest energy resulted from the partial change in entropy associated with alterations in the proton concentration after neutralization reactions. Investigation of the potentiodynamic profile of the current density and conduction of electrochemical impedance spectroscopy helped to evaluate the practical reversibility of the proton electroinsertion process and to maximize the energy storage efficiency. The electrochemical quartz crystal microbalance data allowed for proposal of a charge compensation mechanism and for assessment of the proton selectivity of the modified electrodes. On the basis of the charge/discharge curves recorded from pH=1 to pH=6, the neutralization pseudocapacitor harvested 30.7kJ per mol of electroinserted proton during H2SO4 solution neutralization, which corresponded to 54.6% of the neutralization enthalpy. Together, these results demonstrated the viable application of this methodology to harvest energy during acid wastewater treatment.
Abstract This chapter reports the main techniques used to synthesize powders and films of heterogeneous catalysts and photocatalysts, often used for similar processes. Traditional preparation processes of bulky (photo)catalysts including precipitation, sol–gel technique, hydrothermal or solvothermal method, solid-state reactions, and flame syntheses were briefly described. The sonochemical method and microwave irradiation technique were also considered. The syntheses of supported catalysts by different techniques, including deposition–precipitation, impregnation, and wet coating technologies were also described. Moreover, a survey is reported of methods to deposit thin films of catalysts on various supports such as deposition–precipitation, impregnation, chemical and physical vapor deposition, or electrodeposition.
In order to improve the negative electrode characteristics of a graphite electrode in a propylene carbonate (PC)-containing electrolyte, we have prepared a graphite negative electrode coated with a water-soluble anionic polymer as a binder for composite graphite electrodes. The electrochemical characteristics of the coated graphite were evaluated by cyclic voltammetry and charge–discharge cycle tests. The coated graphite negative electrode showed a stable Li+ ion intercalation/deintercalation reaction without the exfoliation of the graphene layers caused by the co-intercalation of the PC solvent in the LiClO4/PC solution. The charge–discharge characteristic of the coated graphite negative electrode in a PC-containing electrolyte was almost the same as that in ethylene carbonate-based electrolyte.
This paper presents the life cycle cost analysis of the single slope passive and hybrid photovoltaic (PV/T) active solar stills, based on the annual performance at 0.05m water depth. Effects of various parameters, namely interest rate, life of the system and the maintenance cost have been taken into account. The comparative cost of distilled water produced from passive solar still (Rs. 0.70/kg) is found to be less than hybrid (PV/T) active solar still (Rs. 1.93/kg) for 30years life time of the systems. The payback periods of the passive and hybrid (PV/T) active solar still are estimated to be in the range of 1.1–6.2years and 3.3–23.9years, respectively, based on selling price of distilled water in the range of Rs. 10/kg to Rs. 2/kg. The energy payback time (EPBT) has been estimated as 2.9 and 4.7years, respectively.
A precise understanding of the intrinsic electrochemical characteristics of electrode active materials is significant for designing next-generation Li-ion batteries (LIBs). Spinel phase LiNi0.5Mn1.5O4 (LNMO) is a promising cathode material, because of its high operation voltage (~4.7V vs. Li+/Li). We demonstrate that the electrochemical characteristics of an LNMO particle electrode, without any interference additives, may be probed by the single particle measurement technique. This technique provides explicit evidence that single spherical LNMO particles with diameters of 10–20μm are reliably rechargeable, exhibit high discharge rate capability, and produce an exchange current density of ~0.2mAcm−2 for the Ni4+/Ni2+ redox couple in the depth of discharge (DOD) range of 10–40%, based on quasi-Tafel analysis. This work effectively demonstrates the efficacy of using the single particle measurement technique to evaluate the intrinsic properties of 5V class cathode materials.
Today, new services creation is very crucial for RFID (radio frequency identification) products manufacturers. A newly successful RFID application can enhance their change in organization and to manage growth in an increasingly competitive environment. But, there is a high failure rate in new products development processes. Thus, RFID manufacturers need an effective tool to assist them to create novel RFID product functions. This study proposes a newly systematic approach called QT-Kano model which integrates three management tools, quality function deployment (QFD), the theory of inventive problem solving (TRIZ), and a refined Kano’s model, to create new product functions of RFID products. In QT-Kano model, QFD has firstly been used to transform customer demands into engineering quality characteristics. Secondly, based on the contradiction relationship between those engineering quality characteristics, the novel designed functions are created by TRIZ. Finally, to reduce the high failure rate in new products development processes, a refined Kano’s model are applied to offer a better understanding from customer’s viewpoint and to assist service designers focusing on the most important attributes that need to be improved. A real case of RFID product function development is demonstrated to show the effectiveness of the proposed model.
