Abstract In this paper, the possibility of using lithium-ion batteries in hybrid stand-alone power sources is considered. The article gives a comparative analysis of the energy and performance characteristics, the service life of lead-acid and lithium-ion batteries. It is shown that the longer service life and the specific energy density, the absence of the need for constant monitoring of the main parameters and the ability to preserve the original capacity at increased discharge currents, open the possibility of using lithium-ion batteries in hybrid stand-alone power sources.

In the past few years, the growing need for alternative power sources has generated considerable interest in the field of energy harvesting. A particularly exciting possibility within that field is the development of fabrics capable of harnessing mechanical energy and delivering electrical power to sensors and wearable devices. This study presents an evaluation of the electromechanical performance of hollow lead zirconate titanate (PZT) fibers as the basis for the construction of such fabrics. The fibers feature individual polymer claddings surrounding electrodes directly deposited onto both inside and outside ceramic surfaces. This configuration optimizes the amount of electrical energy available by placing the electrodes in direct contact with the surface of the material and by maximizing the active piezoelectric volume. Hollow fibers were electroded, encapsulated in a polymer cladding, poled and characterized in terms of their electromechanical properties. They were then glued to a vibrating cantilever beam equipped with a strain gauge, and their energy harvesting performance was measured. It was found that the fibers generated twice as much energy density as commercial state-of-the-art flexible composite sensors. Finally, the influence of the polymer cladding on the strain transmission to the fiber was evaluated. These fibers have the potential to be woven into fabrics that could harvest mechanical energy from the environment and could eventually be integrated into clothing.

High Cellulose

The search for alternative sources of cellulose is currently getting special importance. Miscanthus holds promise as a cellulosic feedstock with a high potential for industrial-scale cultivation. The present study reports an analysis done for seven years of the chemical composition of the aboveground biomass of Miscanthus var. Soranovskii as a source for producing bioethanol. The aboveground biomass of Miscanthus was found to have a high cellulose content (about 50%), irrespective of the age, and it is therefore reasonable to utilize this cultivar for bioethanol production.

Accurate Performance

The Two-Way Ranging (TWR) method is commonly used for measuring the distance between two wireless transceiver nodes, especially when clock synchronization between the two nodes is not available. For modeling the time-of-flight (TOF) error between two wireless transceiver nodes in TWR, the existing error model, described in the IEEE 802.15.4-2011 standard, is solely based on clock drift. However, it is inadequate for in-depth comparative analysis between different TWR methods. In this paper, we propose a novel TOF Error Estimation Model (TEEM) for TWR methods. Using the proposed model, we evaluate the comparative analysis between different TWR methods. The analytical results were validated with both numerical simulation and experimental results. Moreover, we demonstrate the pitfalls of the symmetric double-sided TWR (SDS-TWR) method, which is the most highlighted TWR method in the literature because of its highly accurate performance on clock-drift error reduction when reply times are symmetric. We argue that alternative double-sided TWR (AltDS-TWR) outperforms SDS-TWR. The argument was verified with both numerical simulation and experimental evaluation results.

This paper presents methods to develop metrics that compare Big Deal journal packages and the journals within those packages. Deal-level metrics guide selection of a Big Deal for termination. Journal-level metrics guide selection of individual subscriptions from journals previously provided by a terminated deal. The paper argues that, while the proposed metrics provide helpful quantitative data for comparative analysis, selection of individual subscriptions must also involve informed judgment about a library’s subject coverage needs and alternative sources of access. The paper also discusses how replacing a Big Deal with a reduced number of individual subscriptions may affect the collections budget, use of other resources, and interlibrary loan.

AbstractModern health care and disaster response are inextricably linked to high volume, reliable, quality power. Disasters place major strain on energy infrastructure in affected communities. Advances in renewable energy and microgrid technology offer the potential to improve mobile disaster medical response capabilities. However, very little is known about the energy requirements of and alternative power sources in disaster response. A gap analysis of the energy components of modern disaster response reveals multiple deficiencies. The MED-1 Green Project has been executed as a multiphase project designed to identify energy utilization inefficiencies, decrease demands on diesel generators, and employ modern energy management strategies to expand operational independence. This approach, in turn, allows for longer deployments in potentially more austere environments and minimizes the unit's environmental footprint. The ultimate goal is to serve as a proof of concept for other mobile medical units to create strategies for energy independence. (Disaster Med Public Health Preparedness. 2014;0:1–8)

AbstractThe main objective of this paper is to analyze one of the alternative sources of financing - equity crowdfunding - from the point of view of managerial processes. Based on the case study analysis and the comparative analysis the problems and challenges of raising funds using equity crowdfunding are discussed, comparing the findings with the issuing of shares. The analysis show that although many of the activities undertaken in raising funds through issuing shares and equity crowdfunding are similar, the managerial processes in the case of equity crowdfunding require from the company first of all building and caring about relationships with investors, rather than showing and proving effectiveness. In exchange for the low legal requirements, the equity crowdfunding investors expect good communication even if the promises are not fulfilled.
