The clean development mechanism (CDM) provides industrialized countries with an incentive to invest in emission reduction projects in developing countries to achieve a reduction in CO₂ emissions at lowest cost that also promotes sustainable development in the host country. Windmill pumps could be of interest under the CDM because they directly displace greenhouse gas emissions while contributing to sustainable rural development. This study aims to assess the maximum theoretical as well as the realistically achievable CDM potential of windmill pumps in India.

To estimate the CDM potential of windmill pumps in case of electricity replacement (by the substitution of electric motor pumps) regional baseline(s) has been used whereas in case of diesel replacement (by the substitution of diesel engine pumps) the IPCC emission factor(s) has been used. The authors have analyzed the financial feasibility of five designs of windmill pumps at ten select locations in India to justify the financial additionality of windmill pump‐based CDM projects. To analyze the future dissemination levels of windmill pumps logistic growth model has been used.

The annual CO₂ emissions mitigation potential through windmill pumps in India could theoretically reach five million tones. Under more realistic assumptions about diffusion of windmill pumps based on past experiences with the government‐run programmes, annual CER volumes by 2012 could reach 13,000‐46,000 and 0.07‐0.3 million by 2020. This would require that the government sets the subsidy level for windmill pumps at a level that allows them to become viable with the CER revenue. From a macro‐economic point of view, this makes sense if the sustainability benefits are deemed sufficiently high to warrant promotion of this project type.

The paper illustrates the vast theoretical potential of CO₂ mitigation by using windmill pumps for irrigation water pumping in India.

THE usual method of driving aero‐generators is by means of a small windmill mounted on the shaft of the generator, the contour of the latter being streamlined. By this means a separate prime mover is dispensed with, while, if the windmill is placed in the slip‐stream of the main airscrew, some of the lost energy is re‐generated. The inherent drawback to this form of drive is, however, that the speed of a normal windmill—and hence of the generator armature—varies with the speed of the aircraft, and many methods have been devised to overcome this trouble.

Social capital plays an important role in transforming knowledge within and across inter-firm business networks in industries. The purpose of this paper is to explore different kinds of transfer mechanism such as “bonding,” “bridging,” and “protecting” within a case network of the Danish offshore windmill industry. Its aim is to describe how these mechanisms interactively support value co-creation among the involved enterprises and how social capital, residing in the relationships between actors from the firms, is influenced by the different transfer mechanisms.

Based upon a single case study, the paper demonstrates “bonding,” “bridging,” and “protecting” as distinct, yet related, mechanisms for inter-firm business networking. The sample used covers selected key actors from the network as well as third-party experts from the Danish windmill industry, which together represent the most important knowledge-offering and knowledge-demanding domains.

Activities associated with “bridging” and “bonding” clearly matter for creating value for the business network and the industry alike, as they are supportive of strategic capability development (for instance, high-skilled work). While producers and supply companies apply such “bridging,” “bonding,” and additional “protecting” mechanisms based upon their predominant position, small- and medium-sized enterprises (SMEs), however, need to shape teams to do so. A major finding of the study is, thus, that team-based interrelationships among SMEs activate “bridging,” “bonding.” and “protecting” initiatives which are particularly supportive of capability improvement and industry growth. They enable the transfer of relevant capabilities between different projects where actors within SMEs organizations learn to activate and use such knowledge transfer mechanisms. Moreover, asymmetrical dependency-relationships can be partly overcome by shaping and using the mechanisms on the part of SMEs in the network.

To date, brokerage is still an under-explored topic with regard to inter-firm business networks. This case study contributes to the research by illustrating important and distinct qualitative aspects of brokerage, which are conceptualized as “bonding,” “bridging,” and “protecting” initiatives on the part of brokers. The study highlights that not only strong actors with central positions can step into the role as a broker. Even less resourceful actors within asymmetrical relations can act as broker and compensate a lack of resources or strengthen their position within the industry network. Consequently, value co-creating processes within industry networks can also be boosted by brokerage initiated by small companies.

The purpose of this paper is to investigate the characteristics of PCGEs used in a small‐scale windmill in terms of the number of PCGEs.

Experiments were performed in cases where one, two, or four PCGEs are attached to the frame of the windmill, with optimization of different gap distances between exciting and secondary magnets carried out to determine the optimal configuration for generating the peak voltage and harvesting the maximum wind energy for the same range of wind speeds.

The experimental results show that the prototype can harvest energy in urban regions with low wind speeds and convert the wasted wind energy into electricity for city use.

This paper aims to present a low-cost, edge-fed, windmill-shaped, notch-band eliminator, circular monopole antenna which is practically loaded with a complementary split ring resonator (CSRR) in the middle of the radiating conductor and also uses a partial ground to obtain wide-band performance.

To compensate for the reduced value of gain and reflection coefficient because of the full (complete) ground plane at the bottom of the substrate, the antenna is further loaded with a partial ground and a CSRR. The reduction in the length of ground near the feed line improves the impedance bandwidth, and introduced CSRR results in improved gain with an additional resonance spike. This results in a peak gain 3.895dBi at the designed frequency 2.45 GHz. The extending of three arms in the circular patch not only led to an increase of peak gain by 4.044dBi but also eliminated the notch band and improved the fractional bandwidth 1.65–2.92 GHz.

The work reports a –10dB bandwidth from 1.63 GHz to 2.91 GHz, which covers traditional coverage applications and new specific uses applications such as narrow LTE bands for future internet of things (NB-IoT) machine-to-machine communications 1.8/1.9/2.1/2.3/2.5/2.6 GHz, industry, automation and business-critical cases (2.1/2.3/2.6 GHz), industrial, society and medical applications such as Wi-MAX (3.5 GHz), Wi-Fi3 (2.45 GHz), GSM (1.9 GHz), public safety band, Bluetooth (2.40–2.485 GHz), Zigbee (2.40–2.48Ghz), industrial scientific medical (ISM) band (2.4–2.5 GHz), WCDMA (1.9, 2.1 GHz), 3 G (2.1 GHz), 4 G LTE (2.1–2.5 GHz) and other personal communication services applications. The estimated RLC electrical equivalent circuit is also presented at the end.

Because of full coverage of Bluetooth, Zigbee, WiFi3 and ISM band, the proposed fabricated antenna is suitable for low power, low data rate and wireless/wired short-range IoT-enabled medical applications.

The antenna is fabricated on a piece (66.4 mm × 66.4 mm × 1.6 mm) of low-cost low profile FR-4 epoxy substrate (0.54 λ_g × 0.54 λ_g) with a dielectric constant of 4.4, a loss tangent of 0.02 and a thickness of 1.6 mm. The antenna reflection coefficient, impedance and VSWR are tested on the Keysight technology (N9917A) vector network analyzer, and the radiation pattern is measured in an anechoic chamber.

THE Cierva autogyro is a windmill of low pitch whose plane is inclined at a small angle to the relative wind; this windmill takes the place of the wing system of an ordinary aeroplane. The windmill rotates on a ball bearing, and each blade is hinged on a ball bearing, whose axis lies in the plane of rotation so that the blades are free to flap in a direction normal to this plane. In flight the windmill rotates freely under the influence of the relative wind caused by the forward or downward motion of the machine, while the blades are prevented from departing far from the plane of rotation by centrifugal force, but execute a slight flapping oscillation relative to the plane of rotation under the influence of the unsymmetrical aerodynamic forces.

Analyzes the communication processes from both a management and an employee viewpoint during a corporate‐value implementation process at NEG Micon, a Danish windmill company.

Examines the reasons for the introduction of new values at the company, the way in which they were formulated and how they were communicated.

Reveals that the shop‐floor workers did not feel that the wording of the value statement was directed at them; some identified a discrepancy between words and practice, because managers themselves did not live up to the wording of the values, which clearly caused frustration and disappointment; managers had not evaluated their communication efforts or considered how the employees had interpreted and identified with the values.

Contends that managers need to take newer communication theory into consideration in order to be aware of what might go wrong in a communication process. They also need to consider both the daily working context of the employees and the historical and situational context of the organization before they launch a value project.

Argues that the financial problems facing the company and the threat to people's jobs were important reasons that few employees identified with the values; in this respect, it seems relevant to ask whether values are the ideal management tool in times of financial crisis.

Illuminates the problems that may arise during an organization's introduction of a new value statement and offers recommendations for future value‐implementation efforts in organizations.

Many firms are now undertaking their final analysis of the effects on their businesses of Britain's entry into the E.E.C. New opportunities in Europe and new threats at home are being anticipated and planned for. One obvious fact that is being focussed upon by many is the phased elimination over the next five years of tariff barriers between Britain and the six present member countries. This leads firms to examine their pricing policies for Europe, if they are already operating there, and ponder such questions as whether the tariff saving is to be passed on to the consumer in the form of a price reduction, or retained by the firm. Alternatively, if firms are not already operating in Europe then the tariff reductions are seen as an opportunity for them to consider marketing there. We attempt here to explore the effects of Britain's entry on the overall marketing strategies of British firms in Europe and to put the tariff reduction question into its broad commercial perspective.

This paper aims to analyze the communication processes from both a management and an employee view during a corporate value implementation process within a Danish windmill company. The purpose of this paper is to develop further understanding of the potential problems that may occur during such a process within an organization.

The paper is a case study based on a social constructionist approach. A multi‐dimensional model of reception analysis is proposed in order to capture employees' readings of value statements.

The study shows that the distance between top management's views on the values and employees' perceptions is noteworthy. This distance is primarily caused by circumstances in the case company's historical and situational context. One of the questions this paper raises is whether values are an ideal management tool in times of an organizational financial crisis.

This paper only focuses on one organization. Additional research is needed in other organizations attempting to communicate values internally in times of crisis.

Managers need to take newer communication theory into consideration in order to be aware of what might go wrong in a communication process. They also need to consider both the daily working context of the employees and the historical and situational context of the organization before they launch a value project. The communicative competences of middle managers and their capability to enter in dialogue with the employees should also be taken into consideration.

The research illuminates the potential problems that may occur during an organization's value process and offers recommendations for future value implementation efforts in organizations.

The purpose of this publication is to present a didactic concept with the targeted impact of a positive future vision. This paper reflects the effect of local educational action on the development of regionally optimised visions in rural regions of a European industrial state, compared with a rural region in the developing country of Senegal.

An assessment and analysis of two conceptual approaches to education and technology is conducted with a view to participating in a future multicultural participatory design process, and identifying the chances that communities have to build future‐oriented structures that support local roots and development.

In the short‐term, the technological and material results are the targeted localisation of a windmill in the (physical and cultural) countryside. In the long‐term, educative and social results are expected to strengthen local civil society, which is initiated by empowering students through their self‐responsibility in the Alpine region of Greifenburg, Austria. The “windmill” in the region is a publicly visible sign and a technology‐based icon in the landscape, based on local consensus on several levels and inspiring further regional consensus on energy, climate protection and its active creation through entrepreneurship in civil society.

Technology serves as a catalyst to trigger social cohesion among multiple cultures in a region and to enhance conviviality.
