Does positive affect influence the effective usage of a Decision Support System?

This study examines the impact of positive mood on the effective usage of a Decision Support System (DSS). Using current cognitive theories, a theoretical argument about DSS usage is developed. This argument is then investigated via a lab experiment. The results of the lab experiment show that decision makers in positive mood used a greater number of informational cues provided by the DSS and made more accurate judgments.     

The homemaker’s hydrogen generator: A report for IAHE student hydrogen design competition 2010

As a highly reactive gas, hydrogen presents significant challenges for its acquisition and safe storage. Consequently, the viability of a sustainable hydrogen economy greatly depends on the development of an efficient, cost-effective method of hydrogen production. One model for addressing this challenge is to deploy portable hydrogen generators for the home. The Princeton University Chapter of the International Association for Hydrogen Energy (IAHE-PU) has designed and created a generator that produces hydrogen through water electrolysis and optimizes cost effectiveness and portability while maximizing hydrogen output.For our proof-of-concept, the system utilizes simple household items with a Sharp ND130UJF 130W solar panel. In our design, Ni electrodes submerged in 8 M KOH solution in six glass containers were utilized to power an external circuit. Over 1 h, our system produced 8.61 L of hydrogen gas at an estimated cost of $8.58 per kilogram of hydrogen gas over the 25-year lifetime of the solar panel.     

Diversification of Neu differentiation factor and epidermal growth factor signaling by combinatorial receptor interactions

The ErbB family includes two receptors, ErbB-1 and ErbB-3, that respectively bind to epidermal growth factor and Neu differentiation factor, and an orphan receptor, ErbB-2. Unlike ErbB-1 and ErbB-2, the intrinsic tyrosine kinase of ErbB-3 is catalytically impaired. By using interleukin-3-dependent cells that ectopically express the three ErbB proteins or their combinations, we found that ErbB-3 is devoid of any biological activity but both ErbB-1 and ErbB-2 can reconstitute its extremely potent mitogenic activity. Transactivation of ErbB-3 correlates with heterodimer formation and is reflected in receptor phosphorylation and the transregulation of ligand affinity. Inter-receptor interactions enable graded proliferative and survival signals: heterodimers are more potent than homodimers, and ErbB-3-containing complexes, especially the ErbB-2/ErbB-3 heterodimer, are more active than ErbB-1 complexes. Nevertheless, ErbB-1 signaling displays dominance over ErbB-3 when the two receptors are coexpressed. Although all receptor combinations activate the mitogen-activated protein kinases ERK and c-Jun kinase, they differ in their rate of endocytosis and in coupling to intervening signaling proteins. It is conceivable that combinatorial receptor interactions diversify signal transduction and confer double regulation, in cis and in trans, of the superior mitogenic activity of the kinase-defective ErbB-3.     

High-Q Above-IC Inductors Using Thin-Film Wafer-Level Packaging Technology Demonstrated on 90-nm RF-CMOS 5-GHz VCO and 24-GHz LNA

High-Q inductors are important for the realization of high-performance, low-power RF-circuits. In this paper, on-chip inductors with Q-factors above 40 have been realized above the passivation of a 90-nm RF-CMOS process using wafer-level packaging (WLP) techniques . The influence of a patterned polysilicon and metal ground shield on the inductor-Q is compared and the influence of highly doped active area underneath the inductors is shown. A 5-15 GHz above-IC balun has been realized on 20 Omegamiddotcm silicon with the use of patterned ground shield. The technology is demonstrated by a low-power 90-nm RF-CMOS 5-GHz VCO with a core current consumption of only 150 muA with a 1.2-V supply, and a 10% tuning range with a worst case phase noise of -111 dBc/Hz at 1-MHz offset. A 24-GHz single-stage common-source low-noise amplifier has been realized, with a noise figure of 3.2 dB, a gain of 7.5 dB, and a low power consumption of 10.6 mW

Incorporating Environmental Value and Externality in Project Evaluation as a Sustainability Indicator to evaluate Bangladesh Water Development

A major difficulty of conventional cost benefit analysis is that it will allow choosing an alternative among others only on the criterion of economic efficiency: that the selected project or activity has been proven to produce economic benefits over costs for the period of the project. An analysis of this kind generally does not create a problem if the costs and benefits series are easy to quantify and clearly identifiable. However, almost all projects linked with the environment are clear exceptions to this category. Many environmental projects are facing a difficulty of evaluating the success based on economic efficiency due to two reasons: (a) environmental benefits are difficult to quantify and (b) environmental interactions that will cause severe externalities are difficult to predict. The main objective of this paper is to suggest a new method that can be used to overcome such difficulties in environmental projects. Data used in this analysis will demonstrate a practical approach to evaluate environmental projects. The evaluation proposed is different to traditional analysis in that it has been based on a large programme of primary research and has included efforts to achieve a consensus of all stakeholders, including those directly involved in project implementation.     

Do men and women use feedback provided by their Decision Support Systems (DSS) differently

This study investigates the effect gender has on the use of computer-based feedback and the impact that this feedback has on mood. The decision making process of men and women are investigated via a laboratory experiment using a previously validated Decision Support System (DSS) and a commonly used and negatively framed feedback. Grounded in human-computer interaction theories highlighting the strong social component of computers and social feedback theories showing that men and women react to negative feedback differently, we argue that the commonly used outcome feedback in DSS studies will influence both the decision accuracy of male and female users and their moods differently. The results, which support our basic theoretical argument, indicate that outcome feedback (in particular the more negative outcome feedback) improved the decision accuracy of the female users compared to their male counterparts. The results also indicate that the outcome feedback affect the overall mood of men and women differently as well. The overall moods of the female subjects were significantly less positive before and after completing the task (receiving this commonly used negative form of feedback), the moods of the male subjects before and after completing the task (receiving the same negative feedback) did not change. These results not only extend prior DSS feedback studies but also highlight the need and provide support for examining gender differences in such investigations.

High density, low leakage Back-End 3D capacitors for mixed signals applications

ITRS 2018 compliant capacitors have been developed with low-cost anodic Ta₂O₅ material. High capacitance values and very low leakages have been obtained on low thermal budget capacitors fabricated with a CMOS-compatible process. High densities in the order of 10 fF/μm² and very low leakages down to 10⁻⁷ A/cm² at 10 V have been measured electrically. All these features, combined with a high breakdown voltage superior to 37 V and linearity coefficient down to 82 ppm/V, make such capacitors great candidates for both analog precision and decoupling applications.
