Fabrication of a dielectrophoretic chip with 3D silicon electrodes

This paper describes a device in which the DEP electrodes form the channel walls. This is achieved by fabricating microfluidic channel walls from highly doped silicon so that they can also function as DEP electrodes. The device is fully enclosed and there is no fluidic leakage due to lead-outs. The electrode arrangement minimized the electrical dead volumes such that the DEP force is always sufficient to overcome Stoke's force and concentrate the cells and beads at the nominal operating potential of 25 Vp–p. The device has been tested successfully with yeast cells. When the actuation signal was increased to 13 Vp–p, cells began to move towards the tip of the DEP electrodes, where the electric field gradient was highest. As the actuation voltage increased, the cells moved faster. For 25 Vp–p, a stable equilibrium of cell concentration pattern was achieved in 10–13 s.
Efficient Market Design and Public Goods, Part I: Economic Models

The theory used by economists to support restructuring of the electric power industry has ignored several important technological constraints and public goods that affect the way in which power is delivered. Similarly, engineers, by using security-constrained optimization to incorporate the demand for reliability, have failed to properly define the economic problem. In this two-part paper we attempt to remedy the deficiencies of both the economists approach and the security-constrained optimization approach through a collaboration of economists and engineers to examine the theoretical properties of a networked power system that provides optimal resource allocation.
Current benchmarking results of EUV resist at Selete

The main challenge facing the implementation of EUV resist and processing has been concurrent achievement of high sensitivity, high resolution, and low line width roughness (LWR). In order to improve the performance of EUV resist, Selete is actively pursuing its benchmarking. The results from this benchmarking were found to be as follows: Esize improved with the increasing capability of EUV pattern exposure. Sensitivity improved during this year. Resolution is found to be almost sufficient for 32-nm half-pitch (hp), but not quite good enough for 22-nm hp. Resist blur of the resist, which marked good score in benchmarking, is found to be 10nm to 11nm. LWR is still far from its target value.
Design of a K‐band reflectarray antenna using double square ring elements

Design of a K‐band reflectarray antenna using 15 × 15 double square ring elements printed on a single substrate and backed by a ground plane separated by an air layer is proposed. The double square ring element supplies a 530° dynamic range of the reflection phase variation, and the phasing curves are nearly linear. A prototype is manufactured and tested, and good agreements between simulation and measurement are demonstrated. The measured gain is about 23 dBi at the center frequency 24 GHz, and the 1‐dB gain bandwidth is about 20%. © 2011 Wiley Periodicals, Inc.

Pull-Out Bond Strength of Titanium Post Cemented with Novel Fast-Setting Calcium Silicate Cement

Objective: The aim of this study was to compare the pull-out bond strength of prefabricated titanium posts cemented with novel fast-setting calcium silicate, zinc phosphate, or glass ionomer cements. Methods: Sixty extracted human maxillary incisors were selected and received root canal treatment. Post space was prepared for titanium ParaPost XP size 5 (diameter=1.25 mm). The posts were cemented using novel calcium silicate cement, zinc phosphate cement, or glass ionomer cement (n=20). Specimens were stored in phosphate-buffered saline for 4 weeks. Subsequently, the posts were subjected to axial tensile force until bond failure. Data were analyzed by one-way ANOVA followed by multiple comparisons. Results: The posts cemented with novel calcium silicate cement (10.5±3.8 MPa) demonstrated significantly higher bond strength than zinc phosphate (8.0±2.6 MPa) and glass ionomer cements (8.0±2.7 MPa) (P<0.05). Conclusion: Within the limitation of the study, the pull-out bond strength of titanium post cemented with novel calcium silicate cement in endodontically treated teeth was superior to zinc phosphate and glass ionomer cements.
The double Josephson junction as a sub-single-electron-charge electrometer

The small-capacitance superconducting two-junction system shunted as a whole by a small-size resistor (R/sub S//spl Lt/R/sub Q//spl equiv/h/4e/sup 2//spl equiv/6.47 k/spl Omega/) has been analyzed. The sensitivity of the device to variations of the polarization charge Q/sub 0/ on the common electrode (island) is calculated.

Reconnaissance of the Function of Social Media on Study Habits Of Undergraduate Students in the University of Cape Coast.

The world today is celebrating the improvements in communication technology which has broadened the scope of communication through Information and Communication Technologies (ICTs). Modern Technology in communication no doubt has turned the entire world into a “Global village”. But as it is, technology like two sides of a coin, bring with it both negative and positive sides. The study examined the function of social media on students’ study habit. The study employed a descriptive survey design with a quantitative approach. The stratified and purposive sampling techniques were used to select 217 out of 245 students from level 300(n=111) and 400(n=106)) undergraduate Psychology students. Researchers’-designed questionnaire titled “Usage of Social Media Questionnaire” (USMQ) and ‘‘Students Study Habits Questionnaire” (SSHQ) with Cronbach's Alpha reliability coefficients of 0.74 and 0.83 respectively were used to collect data for the study. WhatsApp and Facebook were the predominant social media sites students were exposed to. Students were found to be addicted to social media usage. The study revealed no statistically significant differences in the usage of social media with regards to gender and age. Social media was found to significantly influence the study habits of respondents. Specifically, increased usage of social media resulted in negative study habit. It was recommended that academic counsellors together with the management of tertiary institutions should map out strategies (eg., integration of topics on the pros and cons of social media use in the lecture theatre in various courses of study by lecturers and restriction of social media use during lectures by students) to reduce students’ addiction to social media platforms. It also recommended to students to allow quality time for studies and use of social media for the right purposes, especially their academic studies.
Portable Falling Weight Deflectometer Study

This research investigated the effectiveness of the Portable Falling Weight Deflectometer (PFWD) for evaluating the support capacity of pavements during the spring thaw and evaluating the adequacy of subgrade and base compaction during construction. The performance of ten asphalt and gravel surfaced low volume roads were evaluated through spring thaw and recovery. Comparisons were made to the traditional FWD as well as other portable measuring devices. It was shown that the PFWD was able to follow seasonal stiffness variations and compared well with FWD derived moduli on both asphalt and gravel surfaces. Recommendations were made for using a PFWD to determine when to place and remove load restrictions. Field and laboratory tests were conducted to develop correlations between composite modulus, percent compaction, and water content for a range of aggregate types typical of New England. Comparisons were made between multiple PFWDs. A tentative technique was recommended for using a PFWD for compaction quality control for aggregate base and subbase courses. This is based on a rough equivalency between the PFWD composite modulus and percent compaction for aggregate at optimum water content. Factors are provided to correct the modulus at the field water content to the equivalent value at optimum.
Awareness on legal aspect of physical restraining among nurses in National Institute of Mental Health in Sri Lanka

Background Physical restrain was one of the ancient interventions used to control psychiatric patients. It should be used for a short period, and a registered nurse is responsible to protect rights, treat with dignity and provide high quality care during patient restraining. The objective of the study was to assess knowledge, attitudes and practices on physical restraining among nurses in psychiatric wards and units in Sri Lanka.Methods A descriptive cross-sectional study was conducted in the National Institute of Mental Health in Sri Lanka and a pretested self-administered questionnaire was used for data collection. The associations among the knowledge, attitudes, practices and socio-demographic factors were assessed.Results Knowledge of nursing officers’ regarding physical restraining was at a satisfactory level and increasing with working experience, getting formal education of physical restraining. However, there is no significant association between the knowledge on physical restraining and working experience, formal education of physical restraining and working places. In addition, most of attitudes and practices regarding physical restraining among nurses were not significantly associated with working experience, formal education of physical restraining and working places.Conclusions Participants had satisfactory knowledges, positive attitudes and favorable practices regarding physical restraining. Continuous in-service education programs important to improve the knowledge, attitudes and practices on physical restraining among nurses.
Compliance and Stress Sensitivity of Spur Gear Teeth

The magnitude and variation of tooth pair compliance with load position affects the dynamics and loading significantly, and the tooth root stressing per load varies significantly with load position. Therefore, the recently developed time history, interactive, closed form solution for the dynamic tooth loads for both low and high contact ratio spur gears was expanded to include improved and simplified methods for calculating the compliance and stress sensitivity for three involute tooth forms as a function of load position. The compliance analysis has an improved fillet/foundation. The stress sensitivity analysis is a modified version of the Heywood method but with an improvement in the magnitude and location of the peak stress in the fillet. These improved compliance and stress sensitivity analyses are presented along with their evaluation using test, finite element, and analytic transformation results, which showed good agreement.
LOAD-ECCENTRICITY EFFECTS ON COLD-FORMED STEEL LIPPED-CHANNEL COLUMNS

The effects of loading eccentricity on axial strength of cold-formed–steel lipped channels are investigated in a series of 48 individual long-column tests. Experimental results are compared with flexural and torsional-flexural buckling-strength predictions based on the American Iron and Steel Institute (AISI) 1986 specification, with local buckling treated using the uniform-effective-width approach. Widely spaced, rectangular web perforations are modeled using an “unstiffened-strip” method, with the web idealized as two unstiffened elements, one on either side of the perforation. A method for predicting weak-axis flexural buckling and the load–versus–lateral-deflection response of eccentrically loaded, initially imperfect columns is also examined. Estimates of the actual loading eccentricities are made by comparing the predicted and empirical load-versus-deflection responses. Axial strength is shown to be very sensitive to small eccentricities. Conservative strength predictions are obtained with the AISI procedures by including loading eccentricity effects and modeling the perforations using the unstiffened-strip method.
Evaluating damage extent of fractured beams in steel moment‐resisting frames using dynamic strain responses

Delays in the postearthquake safety estimations of important buildings significantly increase unnecessary disorder in economic and social recovery following devastating earthquakes. Providing promptness and objectivity in evaluation procedures, damage detection through a structural health monitoring system using sensors attracts attention from building owners and other stakeholders. Nonetheless, local damage on individual structural elements is not easily identifiable, as such damage weakly relates to the global vibrational characteristics of buildings. The primary objectives of this research are to present and verify a method that quantifies the amount of local damage (i.e., fractures near beam–column connections) for the health monitoring of steel moment‐resisting frames that have undergone a strong earthquake ground motion. In this paper, a novel damage index based on the monitoring of dynamic strain responses of steel beams under ambient vibration before and after earthquakes is firstly presented. Then, the relation between the amount of local damage and the presented damage index is derived numerically with a parametric study using a nine‐story steel moment‐resisting frame model. Finally, the effectiveness of the damage index and an associated wireless strain‐sensing system are examined with a series of vibration tests using a five‐story steel frame test bed.

Multicriterion control charts for electrostatic separation processes

The variability of the output is often deplored by the users of electrostatic separators. The goal of this paper is to point out the effectiveness of multicriterion control charts for monitoring the output variables of electrostatic separation processs. The experiments were carried out on samples of chopped electric cable wastes, similar to those currently treated by the recycling industry. The two output variables considered in the study were the masses of product recovered in the middling and conductive compartments of the collector. When the separation process was under control, the two variables were correlated, and a χ2-type control chart could be established. A simulated out-of-control situation was detected by the multicriterion control chart, though each ouput variable taken independently remained within the control limits.
No Strings Attached: Examining the Relationship between Loosely Coupled Research Partnerships and Innovative Performance

The purpose of this paper is to shed light on the relationship between loosely coupled research partnerships — formal interorganizational agreements through which the in-sourcing firm accesses and adds knowledge from an external partner in exchange for money (e.g. royalties) — and innovation. More broadly, it is one of the first to identify some of the firm-level conditions that compensate for the inherent limitations of this type of research partnership, challenging the implicit assumption that they cannot bring substantial innovation benefits (i.e., generate innovations which are new to the industry). In particular, we illustrate that when firms have an orientation to experiment with knowledge and have slack resources and organizational attention available then loosely coupled partnerships can lead to innovation previously attributed exclusively to tightly coupled partnerships.
Parameter Measurement for Surface-Mounted Permanent Magnet Synchronous Motor Taking Stator Iron Loss into Account

Motor parameters are necessary to achieve several surface-mounted permanent magnet synchronous motor (SPMSM) drive strategies, such as model-based high efficiency control and direct torque control. This article presents a new parameter measurement strategy for vector controlled SPMSM. Iron loss resistance associated with stator iron loss as well as conventional electrical parameters, i.e., electromotive-force (emf) coefficient and stator inductance, are measured on a vector control system. Stator iron loss is measured separately from mechanical and stray losses. As a result, the accuracy on the measurement of iron loss resistance is improved. The validity of the proposed method is confirmed by the comparison between calculated and measured torques.

A PROFILE OF UNINSURED MOTORISTS IN CALIFORNIA

The purpose of the study was to provide data on the characteristics of drivers suspended pursuant to California's financial responsibility law (VC 16070). Two distinct data sets comprised the primary study material: (1) a sample of 125,341 drivers suspended in 1978 for not supplying evidence of insurance following a reportable accident and (2) a sample of zip codes selected to provide a wide range of uninsured motorist rates. Compared to the average California driver, the financially irresponsible driver was found (1) to have a much worse prior accident record; (2) to have a much worse prior traffic conviction record, including major violations; (3) to more often be young; and (4) to more often be male. The zip code analysis indicated that zip codes with high rates of uninsurance had significantly lower median incomes, more poverty level persons, and lower education levels than zip codes with a low rate of uninsurance. In general, the findings closely paralleled those of a 1967 study on the same topic.
Efficient traffic simulation using busses as active sensor network

In this paper we present a traffic simulation system using traffic data gathered from readings by GPS devices installed on board of busses, i.e., busses running on the road are used as a mobile sensor network. Traffic data are inferred from the comparison of data about normal speed and current speed in a certain position. The simulation system was developed to invent mechanisms that use such information for traffic optimization. In particular, simulations allow to manage traffic lights in real time and to control the traffic system in order to give priority to public transportation systems.Copyright © 2011 by ASME
Numerical Investigation of Slider Bearings With Limited Corrugation and Power-Law Lubricant

Performance of slider bearings of infinite width but having corrugation of limited extent is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package. Lubricant is assumed to be a fluid of power-law type. Over a range of the power-law index, effects of the corrugated section’s location on pressure distribution in the bearing’s fluid film and its load supporting capacity is considered. Load-supporting capacity increases with power-law index n, but saturates when n reaches about 1.7. Ratio of load-supporting capacities between corrugated bearing and smooth-surface bearing varies significantly with respect to n when n < [about 0.8], but stays nearly constant at higher n value. Larger corrugation-wave amplitude enhances the difference in load-supporting capacity between corrugated bearings and the smooth-surface one.Copyright © 2011 by ASME
Effect of Repeated External Perturbations on the Reflex Control of Human Posture — Influence of Reflex Delay, Duration and Gain

The aim of the study was to assess the effects of muscle responses on the trunk motions during repeated perturbations by external forces. Patients with low back pain have delayed muscle reflex latencies to perturbations compared with healthy controls. The perturbation provoked trunk accelerations were simulated by a model consisting of four rigid bodies and six force elements representing trunk and hip muscles. The influence of the muscle responses were assessed by varying the reflex delays, the reflex durations, and the reflex gains. Trunk accelerations can be reduced by the simulated muscle responses. The optimal solution is not the result of extreme values of the reflex delay and duration range but of intermediate values. The relationship between the trunk accelerations and the reflex delay and duration respectively can be described by asymmetrical u-shape functions. As patients with low back pain showed delayed reflexes, their trunk motions are probably increased compared with healthy subjects.
First-year engineering students' views of the nature of engineering: implications for engineering programmes

A study was conducted on the views of the nature of engineering held by 114 first-year engineering majors; the study built on prior work on views of the nature of science held by students, their instructors, and the general public. Open-coding analysis of responses to a 12-item questionnaire suggested that the participants held tacit beliefs that engineering (1) involves problem solving; (2) is a form of applied science; (3) involves the design of artefacts or systems; (4) is subject to various constraints; and (5) requires teamwork. These beliefs, however, were often unsophisticated, and significant aspects of the field of engineering as described in the literature on engineering practices were missing from the student responses. The results of this study are important because students' beliefs have a strong influence on what they value in a classroom situation, what they attend to in class, and how they choose to study for a course.
