Collaborative Information Seeking in Digital Libraries, Learning Styles, Users’ Experience, and Task Complexity

The purpose of this study is to examine the relationship between collaborative information seeking and users’ learning style preferences and their experience of information systems. The study investigates the role of four different factors including learning style, task complexity, and user experience in collaborative information seeking in digital environments. Sixty participants (30 pairs) were randomly chosen from volunteer graduate students of Kharazmi University (Iran). Participants completed Kolb’s learning style questionnaire and a user experience questionnaire and then performed two information seeking tasks (one simple and one difficult) in a lab setting. They could exchange information with their partners or a librarian using Skype. The sessions were recorded using Camtasia. The results showed that with an increase in task difficulty, collaborative information seeking activities increased and more interactions with partners and the librarian occurred. The number of executive help-seeking requests was higher than the number of instrumental help-seeking requests. This research confirms that learning style is related to the way users interact with the digital library and help seeking. The research showed that in difficult tasks, the differences among users with different learning styles become more evident, and that generally interactions increase in more difficult tasks. Among the learning styles, the accommodating style had the highest number of relationships with collaborative information seeking variables. Most of the statistically significant relationships between users’ prior computer experience and collaborative information seeking variables were related to the time variable.
Analysis of aural mode operation of passive sonar

The steps which a sonar operator goes through in finally calling "target" while using a trainable beam passive sonar in the aural mode are described. Three distinct processes are identified: (a) single observation, (b) multiple sequential observation, and (c) multiple sweep. Using these concepts and data from two-alternative forced-choice psychoacoustic experiments, one can calculate a transition curve for realistic sonar operator performance. These calculations are compared with transition curves obtained from sonar performances on a more realistic sonar mock-up. The significance of the paper is in the detailed description of the aural process and in the method for calculating aural detection performance.
The Use of Altmetrics as a Tool for Measuring Research Impact

This article provides an introduction to the use of altmetrics as a tool to assess research impact. In particular, it looks at the evidence behind claims that altmetrics allow the impact of research to be measured in days rather than years. Low correlations between altmetrics and article citations make it doubtful that altmetrics can reliably predict future citations. In addition, there are good reasons to qualify statements that altmetrics measure the wider impact of research on society. Librarians should be careful not to overstate the value of altmetrics when recommending their use as a complement to more traditional measures of research quality.
Factors Affecting Driver Speed Choice along Two-Lane Rural Highway Transition Zones

Two-lane rural highways attract trips between traffic generators such as residential villages or small commercial areas and are generally uninterrupted flow facilities that provide a high level of mobility with high posted speeds limits. When passing through developed areas, the posted speed limit may be lowered to encourage reduced vehicle operating speeds. No published guidelines currently exist for the design of transition zones that connect high- to low-speed operating environments on two-lane rural highways. The objective of this research was to collect operating speed and roadway characteristic data along two-lane rural highway transition zones in Pennsylvania to explore the roadway, roadside, and traffic control factors that are associated with driver speed differentials. Single- and multilevel models were estimated and compared. The posted speed limit reduction as well as a change in the paved shoulder width, total number of driveways, various advance warning signs, the transition zone length, and the presence of horizontal curves were shown to increase the expected speed reduction in transition zones in the models. Additionally, drivers entering transition zones at higher speeds were found to have greater speed reductions than drivers entering the transition zone at lower speeds.
Innovation risks of hi-tech start-ups and the key factors to success

This work focuses on the innovation risks that hi-tech start-ups face and the key factors that contribute to the success of these enterprises. Hi-tech start-ups are confronted with three types of risks: (1) technological risk, resulting from the explorative nature of R&D and production of hi-tech products; (2) market risk, as a result of the high uncertainty in the hi-tech product market; and (3) and financial risk. Hi-tech innovation usually requires huge investment. However, most hi-tech start-ups lack long-term investment capability. Accordingly, the authors find seven factors indispensable to a successful hi-tech start-up: enterprising leaders; core technology and root technology; people who have good command of these technologies; efficient incentive mechanism; project selection; backup of venture capital; and quick product entry into the market and solid technical service.

We report the successful monolithic integration of a GaInasp/lnP single-mode ΔK directional coupler switch with a 4-section tunable multiple-quantum-well distributed Bragg reflector laser. We obtain several mW of output power through the switch, with ˜10dB crosstalk either from the internal laser source or with external light injected through the parallel input port.
Morphological analysis of Sanskrit derivation based on word schemes

Usually, Sanskrit derivation description consists in rules of segmentation and concatenation according to the model of morphological analysis based on morphemes. However, there are certain patterns in which the relationships between the form and the meaning of the theoretically segmented subunits are not satisfactorily analyzed. Given this problem, an analysis model based on word schemes is applied to perform a partial and approximate morphological analysis of the Sanskrit lexicon. The word schemes outline bipartite morphological correspondences (derivation processes). The most relevant achievement is a homogeneous list that represents the establishment of natural morphological relationships that from the perspective based on morphemes are left aside. It is concluded that the derivation in Sanskrit is thus an empirical study, effective and intuitive, that benefits from a functional perspective based on use.
Nationalists without a nation: South Moluccan terrorism in the Netherlands

Abstract This article focuses on the phenomenon of South Moluccan terrorism in the Netherlands. Beginning with a historical examination of the colonial relationship between the Netherlands and Indonesia, attention is then given to the circumstances in which some 21,000 South Moluccans came to the Netherlands in the early 1950s, and the social, economic, and political conditions of the South Moluccan community in Holland since then. Then follows a detailed examination of the main incidents of South Moluccan terrorism in the Netherlands which climaxed in a series of violent incidents against Dutch and Indonesian targets in the mid‐1970s. Special attention is placed on the ways in which successive Dutch governments have responded to the various outbreaks of terrorism, as well as to the effects of this terrorism on public opinion. The article then shows what effects South Moluccan terrorism has had on the policies of Dutch and Indonesian governments; on national and international public opinion; on the South .
A Substrate-Dependent CAD Model for Ceramic

In this paper, a substrate-dependent lumped-element model for ceramic multilayer capacitors is presented. The height and dielectric constant of a substrate have a significant impact on the frequency response of a chip capacitor, and these effects cannot be treated independently from the capacitor model. Rather, the equivalent-circuit parameters in the model must be made to vary in accordance with changes in the substrate. The model presented in this paper is suitable for microstrip-mounted components, and has been applied up to 10 GHz for values from 0.5 pF to 0.47 F, and for FR-4 substrates ranging in height from 5 to 62 mil. The modeling and extraction procedure is demonstrated for 0805- and 1206-style capacitors.
Investigating methods of dynamic function allocation for Naval command and control

Dynamic function allocation (DFA) refers to the variable distribution of functions in real time between the system and the operator(s) to achieve optimal system performance. In order to explore the application of DFA in Naval command and control systems, DERA has developed a new research environment, the Naval Dynamic Allocation Research Testbed (N-DART), which is based on the tasks performed by an anti-air warfare controller. Experimental studies are currently being conducted to examine explicit DFA utilising N-DART. The overall system performance is being evaluated in terms of a number of objective measures. N-DART is being further developed to incorporate an implicit mode of DFA based upon a hybrid model of three potential control mechanisms. Implementation issues surrounding system-controlled dynamic allocation of functions in this context are discussed.
Modernizing Models and Management of the Memory Hierarchy for Non-Volatile Memory

Non-volatile memory technologies (NVMs) are a new family of technologies that combine near memory level performance with near storage level cost density. The result is a new type of memory hierarchy layer that exists and performs somewhere between the two. These new technologies offer many opportunities for performanceimprovement, but in order to take advantage of these system design needs to account for their particular characteristics. In this thesis, we focus on how to design memory management and caching systems for NVMs. Our work is broken into three major categories targeting differentprimary performance metrics.1. We study how to design algorithms and memory management to achieve fault tolerance with low cost and efficient recovery using NVMs.2. We design an extension to the traditional model of caching to account for data writes in order to improve NVM device lifetime and energy consumption.3. We investigate how to improve throughput in caches by taking advantage of granularity change in the memory hierarchy.Throughout our work we rely on a blend of theoretical and practical approaches. We provide models for processor faults, cache writebacks, and cache-storage communicationthat isolate the targeted effects from orthogonal complications. For each model, we show worst case theoretical bounds for our algorithms along with proofsthat explain how the benefits are derived. We then take our results and provide empirical evaluations to show their effectiveness in practice. We believe that our ideasand approach provide a solid foundational study on memory hierarchy design in the era of non-volatile memories.
Biocompatible materials for cardiovascular stents

One of the most common interventions performed today is intravascular stenting. A stent is a small tubular device placed into a blood vessel to hold it open. This review covers various aspects of stents from how it is placed into the vessel (e.g. the coronary artery) to the biocompatible materials used (e.g. metal). Mechanical considerations are also being discussed as well as comparison between self-expanding stents and drug eluting stents versus resorbable stents. Other latest research are also covered such as a ’smart stent monitor’ based on sensors providing real-time feedback.

Questionnaire Survey on Bidding in Construction

Bid decisions are heuristic in nature as they are made on the basis of experience, judgment, and perception. In an attempt to uncover the underlying factors that characterize the bidding decision‐making process, a questionnaire survey was conducted among general contractors. This paper contains results based on the response obtained from 400 of the top general contractors in the United States. Characteristics of the group, factors affecting bid/no‐bid and percent‐markup decisions, and policies and practices of the contractors are reported. The study reveals that bidding decisions are greatly influenced by subjectively evaluated criteria, such as type of job, location, size of job, need for work, Owner, subcontractors, degree of hazard, and degree of difficulty. Competition and profitability, although significant, are not the topranked factors.
High-temperature high-bandwidth fiber optic MEMS pressure-sensor technology for turbine engine component testing

Acquiring accurate, transient measurements in harsh environments has always pushed the limits of available measurement technology. Until recently, the technology to directly measure certain properties in extremely high temperature environments has not existed. Advancements in optical measurement technology have led to the development of measurement techniques for pressure, temperature, acceleration, skin friction, etc. using extrinsic Fabry-Perot interferometry (EFPI). The basic operating principle behind EFPI enables the development of sensors that can operate in the harsh conditions associated with turbine engines, high-speed combustors, and other aerospace propulsion applications where the flow environment is dominated by high frequency pressure and temperature variations caused by combustion instabilities, blade-row interactions, and unsteady aerodynamic phenomena. Using micromachining technology, these sensors are quite small and therefore ideal for applications where restricted space or minimal measurement interference is a consideration. In order to help demonstrate the general functionality of this measurement technology, sensors and signal processing electronics currently under development by Luna Innovations were used to acquire point measurements during testing of a transonic fan in the Compressor Research Facility (CRF) at the Turbine Engine Research Center (TERC), WPAFB. Acquiring pressure measurements at the surface of the casing wall provides data that are useful in understanding the effects of pressure fluctuations on the operation and lifetime wear of a fan. This measurement technique is useful in both test rig applications and in operating engines where lifetime wear characterization is important. The measurements acquired during this test also assisted in the continuing development of this technology for higher temperature environments by providing proof-of-concept data for sensors based on advanced microfabrication and optical techniques.

ENERGY AND EXERGY ANALYSIS OF COAL FIRED POWER PLANT

The global trend of growing energy demand, accompanied by the dependency on fossil fuels and their impacts, provokes continuous interests for analyzing equipment efficiency and revision of existing energy production sites. This paper focuses on thermodynamic analysys of a coal-fired power plant "Kolubara - block A5", with respect to the concept of energy losses, production of entropy and exergy destruction.Most significant energy losses occur in the condenser where they are lost to the environment, whereas greatest exergy destruction is found in the boiler. The results of energy and exergy performance of the plant are calculated for maximum load and 75% of the maximum load. Each of the system components is modeled as a "black box", and the energy and exergy balances are determined according to operation data. Thermal efficiency, based on the specific heat input to the steam, was calculated and found to be 32.1% and 33.1%, while the exergy efficiency of the power plant cycle was 30% and 33%, depending on the load.
Waferbonded active/passive vertically coupled microring lasers

We summarize the results of a European Project entitled WAPITI (Waferbonding and Active Passive Integration Technology and Implementation) dealing with the fabrication and investigation of active/passive vertically coupled ring resonators, wafer bonded on GaAs, and based on full wafer technology. The concept allows for the integration of an active ring laser vertically coupled to a transparent bus waveguide. All necessary layers are grown in a single epitaxial run so that the critical coupling gap can be precisely controlled with the high degree of accuracy of epitaxial growth. One key challenge of the project was to establish a reliable wafer bonding technique using BCB as an intermediate layer. In intensive tests we investigated and quantified the effect of unavoidable shrinkage of the BCB on the overall device performance. Results on cw-operation, low threshold currents of about 8 mA, high side-mode suppression ratios in the range of 40 dB and large signal modulation bandwidths of up to 5 GHz for a radius of 40 μm shows the viability of the integration process.

A reconfigurable leaky-wave/patch microstrip aperture for phased-array applications

A novel reconfigurable leaky-wave/patch microstrip aperture is introduced and characterized. The structure consists of a long leaky-wave microstrip antenna that has been segmented into several smaller patch antennas. The multimode structure can be reconfigured into a patch antenna anywhere along the aperture of the leaky-wave antenna with two degrees of freedom. p-i-n-diode switches are utilized to switch between the different aperture configurations. The structure's unique field profile is utilized to minimize insertion loss in the leaky-wave mode and also to maximize isolation between the different aperture ports. Radiation patterns demonstrate excellent radiation characteristics consistent with standard leaky-wave and patch-antenna patterns. The reconfigurable leaky-wave/patch concept is applied to realize some unique multimode array configurations offering wide scan coverage and enhanced flexibility over traditional phased-array systems.
4.2: Integrated Scan Driver with Oxide TFTs Using Floating Gate Method

An on‐glass integrated scan driver is proposed for oxide thin film transistors TFTs with negative threshold voltage. A coupling capacitor and a TFT for setting the initial voltage to the gate of a TFT were added to minimize the off‐state current. Simulated and measured results indicate that the proposed scan driver shows no ripple and fast rise time/fall time of scan outputs. Circuit operation was verified with a 14‐inch AMOLED panel.
A planar silicon photosensor with an optimal spectral response for detecting printed material

In designing the optimum photosensing device for use in the detection of printed material in a reading aid, experimental evidence points out that the device should have a spectral response which matches that of the human eye. It is demonstrated theoretically that for a given set of base-region recombinative properties, there is an optimum base-collector junction depth for achieving the desired visible region sensitivity. In addition, by truncating the collector region with an epitaxial collector-substrate junction, the desired insensitivity to near-infrared can be achieved. For the recombinative properties typical of the experimental planar devices fabricated in the Integrated Circuits Laboratory at Stanford University, it is theoretically shown and experimentally verified that the optimum base-collector and epitaxial junction depths are nominally 2µ and 8µ, respectively. Accomplishment of this in silicon, which was one of the basic objectives of the research, facilitates monolithic integration of the optimum photosensor with the remainder of the reading aid circuitry.
