Low loss HF band SOI wine glass bulk mode capacitive square-plate resonator

This paper reports on the design and electrical characterization of a single crystal silicon micromechanical square-plate resonator. The microresonator has been excited in the anti-symmetrical wine glass mode at a resonant frequency of 5.166 MHz and exhibits an impressive quality factor (Q) of 3.7 × 106 at a pressure of 33 mtorr. The device has been fabricated in a commercial foundry process. An associated motional resistance of approximately 50 kΩ using a dc bias voltage of 60 V is measured for a transduction gap of 2 µm due to the ultra-high Q of the resonator. This result corresponds to a frequency-Q product of 1.9 × 1013, the highest reported for a fundamental mode single-crystal silicon resonator and on par with some of the best quartz crystal resonators. The results are indicative of the superior performance of silicon as a mechanical material, and show that the wine glass resonant mode is beneficial for achieving high quality factors allowed by the material limit.
Morphometric MRI assessment of lumbar region in healthy individuals

Aim: In our study, we aimed to obtain normal anatomical data in healthy individuals by magnetic resonance imaging, which we frequently use in our daily practice. We encounter quite frequently with the lumbar pathologies. To identify the pathological one, the normal one must first be defined. For this, anatomical studies are the most ideal methods, but costly and challenging studies. Morphometric assessment of the lumbar region by magnetic resonance imaging in the normal population is not common in the literature. Material and Methods: The workup of 100 patients who presented to our clinic, did not have low back pain, underwent lumbar MRI examination for different reasons and whose results were reported to be normal, were evaluated using the PACS system. Morphological evaluation of the paravertebral muscles, ligamentum flavum, and the spinal canal was performed on the right and left sides separately. The data were analyzed by age, gender, and body mass index. Results: Forty-nine patients were females, and 51 were males. The mean age of the patient group was 34.62±9.54 years, and mean BMI was 24.96±3.32 kg/m 2 . Ligamentum flavum thickness and muscle areal measurements were similar between both sides. The comparisons of clinical measurements between females and males revealed that the areas of muscles were significantly higher among males and all other measurements were similar between sexes. There was a weak and positive correlation between age and both right and left erector spinae area. The only parameters that weakly and positively correlated with body mass index were right and left erector spinae areas. Conclusion: In our study, we reported the morphological characteristics of the lumbar region in healthy individuals. An increase in the cross-sectional areas of the erector spinae and the spinal canal at the L5-S1 level was observed with the age. An asymmetry may develop in LF measurements with the age. There was also a positive correlation between body mass index and the cross-sectional area of erector spinae .
A New Dual-Frequency Wilkinson Power Divider

In this article, a novel and simple dual-frequency Wilkinson power divider is proposed. Considering that there is only one section of transmission line linking the input port and the output port directly as a part of the transformer, this power divider is very compact. To satisfy the dual-frequency characteristic, the traditional quarter-wavelength transformer is replaced by the structure which consists of a section of transmission line and a parallel stub at the input port. Besides, in order to obtain the ideal isolation with keeping the ideal matching at the output ports, a resistorr R and series LC components are added. Furthermore, closed-form design equations of this proposed power divider are obtained to simplify the design procedure. The simulation results of four examples indicate that all the features of the power divider can be fulfilled at dual-frequency simultaneously. Furthermore, measurement results of a fabricated power divider operating at 1 GHz and 4 GHz verify the design concept of this proposed power divider.
Corporate Social Responsibility Performance and Annual Report Narrative Disclosure Readability.

We examine the effect of corporate social responsibility (CSR) performance on annual report narrative disclosure readability. We find that firms with higher CSR performance provide less readable annual report, especially in the ‘Notes to consolidated financial statements’ (NOTES) section rather than ‘Management Discussion and Analysis’ (MD&A) section. The CSR performance effect is mainly through the channels of firm profitability and financial leverage, supporting shareholder theory and tax shield concern. Meanwhile, we also find that the channels vary with the different motivations of conducting CSR activities. Finally, the CSR performance effect on NOTES section readability significantly becomes weaker during the financial crisis period.
The Relationship between Interpersonal Trust, Employee Satisfaction, and Employee Loyalty

Abstract Employee satisfaction is considered to be one of the most important drivers of quality, customer satisfaction and productivity. In this study we investigate an important driver of employee satisfaction. We argue that interpersonal trust (trust in management and trust in peers) strongly influences employee satisfaction and, as a consequence, employee loyalty. To test the relationships between these constructs we measured trust in management and trust in peers, satisfaction and loyalty of employees of an Austrian company in the energy sector (N = 131). The results of the statistical analysis using structural equation modeling with Partial Least Squares (PLS) confirm a strong link between trust, employee satisfaction and employee loyalty.

Display Type Effects in Military Operational Tasks Using UAV Video Images: Comparison between Two Types of UAV Feeds Mini and MALE (Medium-Altitude-Long-Endurance) UAVs

The increased usage of new technologies in combat requires measuring tools and guidelines that will enable maximal compatibility between technology and users' needs. Specifically, using video feeds retrieved by dismounted soldiers from different types of unmanned aerial vehicles (UAVs) may affect the efficiency level of using such machines. This work follows our previous studies on the type (e.g. size) of displays required by dismounted soldiers to process video feed from UAVs. Twenty two former infantry soldiers with no experience using UAV video feed participated. Three displays were examined using two video feed types (MALE and Mini UAVs) in four different task types (description, direction, orientation, and response). Performance and subjective data were collected. Results show no effect (only some trends) for display type, but significant effect for the interaction between video feed type and task type and display type.
Influence of Plunging Dropshaft Inflow to the Formation of Geyser in Underground Drainage Systems

Vertical drop shafts are used for transferring storm water to underground drainage tunnels. Significant air entrainment is usually observed for plunging-type drop shafts, which could lead to entrapment of air pockets in the surcharged underground drainage tunnel. The entrapped air pockets reduce flood conveying capacity and may be released explosively in the form of geysers. This paper studied the effect of plunging dropshaft inflow and air entrainment on the formation of geysers by physical modeling. Experiments have been performed on a simplified drainage system, which consists of a vertical plunging dropshaft connected to a horizontal pipe with a constant head tank. A steady inflow is established in the dropshaft. An air pocket is released into the horizontal pipe and then release out of the system through the dropshaft. The dynamics of the air pocket in the dropshaft is measured with high speed imaging. When the inflow from plunging dropshaft is small, air entrainment is confined to the top part of the water column. The net rising velocity of air pocket is reduced, due to a net downward velocity. As the inflow increases, the influence of air entrainment extends towards the entire length of dropshaft. The air pocket is much more rapidly accelerated and released, causing strong spewing and expulsion of air and water. A simple theory is postulated to account for the impact of dropshaft inflow on the occurrence of geyser. Observations and theory suggest that the dropshaft inflow could lead to the occurrence of geyser even when the dropshaft to tunnel diameter ratio is above the critical value of 0.6.
Design Team Communication and Design Task Complexity: The Preference for Dialogues

Abstract The way in which dialogues and group meetings affect the progress of multidisciplinary architectural design teams can be easily underestimated by managers. This is due to the importance of group meetings to review designs, share information, make decisions and hence progress the design. The aim of this paper is to discuss how design dialogues and design team meetings facilitate team communication. A review of research into design team communication and performance using a project website provides an insight into how design team members used and changed their synchronous and asynchronous communication while adopting the project web. Case studies were used to investigate changes in communication practices affecting team performance due to project web use. Research findings reveal a preference among design team members for dialogue as their favourite communication medium despite the growing use of asynchronous communication by teams. Results are discussed against research findings from communication in design and management team meetings. Implications for design managers, concerned with improving communications and the management of design, are discussed in the light of the research findings.
Interdisciplinary relationships in the Spanish academic web space: A Webometric study through networks visualization

The aim of this work is to describe the interdisplinary research relationships among several Spanish university departments and research groups located in the Spanish web space. 699 web sites from 2390 were selected according to whether a web site receives or links to at least one of the rest. The links between them were extracted with a commercial crawler in 2004 and then analysed to built a complex directed network of in-links and out-links. The results show that the Spanish academic web space is weakly interconnected both at the level of groups and departments, and that the relationships between disciplines can be appreciated through network graphs. The use of network graphs is a suitable technique to show the transversal relationships among disciplines and to detect incipient research fronts in the web space. The web presence of Experimental and Technological Sciences is higher than Social Sciences and Humanities as well.
Risk Forecast of In-Stent Restenosis by CFD Method

The treatment of plaques near and involving coronary bifurcations (CB) is especially challenging, considering more plaques localized these regions and higher post-interventional in-stent restenosis (ISR) risk, mainly due to hemodynamic injury provoked on the arterial wall. Therefore optimization of stenting should begin with an understanding of how disease localized to these regions and why ISR formed associated with flow patterns. We chose four patients with bifurcation lesions, two patients with ISR and two without ISR according to the follow-up computed tomography angiography (CTA). Based on patient-specific pre-interventional and virtual stented geometries from CTA images, numerical simulation indicated that the wall shear stress (WSS) in stented segments, where the ISR occurred in one year, was lower than those without ISR, however. For bifurcation lesion, the stenting segments WSS is supposed a marker to forecast the ISR risk after stent treatment.
Promptness and dissipative capacity of MR dampers: Experimental investigations

The experimental analyses of response time and dissipative capability of two prototype magnetorheological semi‐active dampers are presented herein. These activities have been conducted during an Italian research project on devices manufactured in Germany. A detailed report of the response time analysis based on experimental data is presented and commented. It is shown how the control delays are strongly dependent on the effectiveness of the electric part of the control hardware, generally being less than 10 ms if special care is paid in designing the whole control chain.
Seismic nonlinear static new method of spatial asymmetric multi‐storey reinforced concrete buildings

In order to obtain the seismic demands of spatial asymmetric multi‐storey reinforced concrete (r/c) buildings, a new seismic nonlinear static (pushover) procedure that uses inelastic response acceleration spectra is presented in this paper. The latter makes use of the optimum equivalent nonlinear single degree of freedom system, which is used to represent the general spatial asymmetric multi‐storey r/c building. For each asymmetric multi‐storey building, a total of 12 suitable nonlinear static analyses are needed according to the new proposed procedure, whereas at least 96 suitable nonlinear dynamic analyses are required in the case of nonlinear response history analysis (NLRHA), respectively. In addition, the present paper provides answers to a series of further questions with reference to the spatial action of the two horizontal seismic components in the static nonlinear (pushover) analyses, as well as to the documented calculation of the available behaviour factor of the asymmetric multi‐storey r/c building. According to the paper, this new proposed seismic nonlinear static procedure is a natural extension of the documented equivalent seismic static linear (simplified spectral) method that is recommended by the established contemporary seismic codes, with reference to torsional provisions. Finally, through a restricted parametric analysis carried out in this paper, a relevant numerical example of a two‐storey r/c building is presented for illustration purposes, where the seismic demand floor inelastic displacements are compared with the respective displacements obtained by the NLRHA. Consequently, the new proposed seismic nonlinear static procedure, which uses inelastic response acceleration spectra, can reliably evaluate the extreme values of floor inelastic displacements (on the flexible and stiff side of the building), as is shown by the above comparisons.

Photonic integrated receiver for 40 Gbit/s transmission

A novel 40 Gbit/s optical receiver is presented. The device consists of a waveguide photodiode integrated with a semiconductor optical amplifier. The receiver has a small signal bandwidth of 39 GHz and a conversion gain of more than 800 V/W. A back-to-back sensitivity of -17 dBm has been demonstrated for non-return to zero data transmission at 40 Gbit/s. A sensitivity of -32dBm or 110 photons/bit has been realised for 40 Gbit/s return to zero transmission with an erbium doped fibre preamplifier and an optical filter.
Water transport, embolism recovery and water storage in trees

The ability to maintain hydraulic continuity in the xylem is essential to supply leaves with the water that must be exchanged for carbon dioxide. The metastable nature of xylem sap causes this system to be inherently vulnerable to failure by rapid vaporization within the conduits. Much of the recent work on hydraulic architecture and cavitation has pursued the elusive mechanism behind apparent hydraulic recovery concurrent with tension in the bulk of the xylem, referred to as “novel refilling”. An investigation into the dynamics of this behavior (Chapter 3) revealed two key artifacts that can produce the appearance of novel refilling when in fact no embolism (and therefore, no recovery) has occurred. A further implication of these artifacts is that plant xylem may be more robust against embolism than previously expected. In the absence of novel refilling, it becomes much harder to reconcile the extreme vulnerability reported for ring porous species. Studies of Robinia pseudoacacia (Chapter 4) address whether the artifacts illuminated in chapter 3 provide insight into the ongoing debate about the cavitation resistance of longvesseled species and whether it is possible to accurately assess cavitation resistance in these species using the centrifuge method.

FieldHelper: a tool to assist the collation of field data and its ingestion into repositories

FieldHelper is a project designed to bridge the gap between researcher and repository. The program is designed to assist the researcher in annotating digital objects with the relevant metadata necessary for ingestion into a number of possible repository targets. The aim is to provide a generic and highly flexible tool applicable to several research disciplines that hides the complexity of a submission information package from the user by using a simple "drag and tag" metaphor. The tool has the capability of not only specifying simple annotations per object but also complex spatio-temporal and abstract relationships between objects.
Facilities management: a “Jack of all trades”?

Despite its rapid development in the last decade, facilities management (FM) stills suffers from an identity crisis as the definition and scope of FM remains a contentious issue. To this end, three fundamental issues are re‐examined in this paper: what FM constitutes; what a facility manager is; and how the FM profession can be enhanced. These issues remain critical as they represent the building blocks of the FM discipline. Without a common platform, the development of FM is likely to be fragmented. An evaluation of the definitions of FM provided in the past suggests that the focus of FM is clearly on the workplace. The key issues confronting FM are the location, type, quantity, quality, content and allocation of the workspace. A professional facilities manager is one who is formally trained and whose main responsibility is the strategic management of the workplace. Three factors are suggested to be important for the development of FM as a professional discipline. They include a clear role and scope of FM in the industry and firm, contribution to the bottom‐line of the firm, and development of specialist knowledge and toolbox for addressing the problems of strategic workplace management. Some potential areas for theoretical developments have been suggested in this paper.
Experimental Study on the Seismic Performance of 3D Joints between Concrete-Filled Square Steel Tubular Columns and Composite Beams

Six three-dimensional (3D) joints between concrete-filled square steel tubular columns and composite steel-concrete beams were tested under bidirectional reversal loads. The primary purpose of this experiment was to investigate the seismic performance of these composite joints, including load-deformation performance, hysteretic behavior, failure modes, and damage patterns, emphasizing the effects of loading history, connection details, and joint geometries. The test specimens exhibited good strength and stiffness retention capacities and excellent energy dissipation. The typical failure mode of the specimens was shear damage of the joint panel. The influence of the bidirectional loading was minor during the initial response of the joint in elastic range; however, it became significant when the joint was loaded into plastic range. The composite action between steel girder and concrete slab enhanced the capacity of the joint in terms of ultimate strength, stiffness and ductility. Concrete encased in the steel tubular column improved the seismic performance of the joints.
Decision support methodologies on the energy efficiency and energy management in buildings

Abstract The aim of the present chapter is to analyse the decision support processes towards energy efficiency and improvement of the environmental quality in buildings. The main criteria in the decision analysis of buildings are categorized. The decision alternatives which may formulate specific actions, or group of actions (strategies) for buildings’ sustainability are analysed. The decision methodologies presented are separated to online (based on real-time operation of buildings) and offline decision approaches. Both approaches are supported by simulation, multi-objective programming optimization techniques, multi-criteria decision analysis techniques and their combinations in order to reach optimum solution, rank alternatives or provide trade-offs between the criteria. The advantages and drawbacks of the various methods are discussed and analysed.
