We report zinc ion conducting thin film polymer based on non-volatile room temperature ionic liquid, with a zinc chloride dissolved in a water and blend with poly(ethylene) oxide in different ratio of salt. The resultant films are free standing, translucent, flexible and elastic. The conductivity measurement of the films was carried out at room temperature to find the highest conductivity films. © 2010 American Institute of Physics.

This paper presents the results of a laboratory study to improve the durability of pervious concrete by using readily available and low-cost techniques. Surface raveling of pervious concrete is a concern for long-term use, and remediation techniques have not previously been investigated. A high void-content pervious concrete was cured in worst-case hot and dry conditions to produce poor surface durability. Pervious concrete mixtures included a traditional binder and one that included a superabsorbent polymer for internal curing. Various remediation methods included overlaying with fresh pervious concrete and applying latex paint, epoxy, or a surface densifier to the pavement before abrasion testing with the ASTM C944 rotary cutter method. Results showed that the durability of the internally cured mixture was superior to that of the traditional mixture. Of the surface-applied materials, epoxy provided the best improvement in durability, followed by latex paint and the densifier. Material analysis showed that modifying a mixture to include superabsorbent polymer was the lowest-cost option. On a poorly performing pervious pavement, latex paint or a thin overlay both had low material costs. Low-cost methods are effective techniques for improving the surface durability of pervious concrete.

A large body of evidence examines the causes of falls but understanding the role of visual impairment as a cause of falls is studied less and, as a result, is less well understood. Local areas require information at local levels to accurately assess the health needs of their populations, such as understanding the impact of falls on local health services. modification of published formula to calculate how a local area can estimate its fall numbers related to visual impairment. the modified formula makes it possible for local areas in england and Wales to project the number of falls related to visual impairment. this formula will help those commissioning falls and fracture pathways to factor in the effect of visual impairment.

Estimating the size of a software system is a critical task due to the implications the estimation has in the management of the development project. There are some widely accepted estimation techniques: Function Points, Use Case Points and Cosmic Points, but these techniques can only be applied after the availability of a requirements specification. In this paper, we propose an approach to estimate the size of an application previous to its requirements specification by using the application language itself, captured by the Language Extended Lexicon (LEL). Our approach is based on Use Case Points and on a technique which derives Use Cases from the LEL. The proposed approach provides a measure of the application's size earlier than the usual techniques, thus reducing the effort needed to apply them. An initial experiment was conducted to evaluate the proposal. © 2014 IEEE.

Understanding the context of a software system during requirements specification is a difficult task. Sometimes application domains are very complex, other times the limits of the application are fuzzy. Thus, it is difficult to elicit and write the initial set of requirements. This difficulty frustrates requirements engineers and restricts the process of analysis, which could lead to a final software requirement specification of low quality. In such situations technologically outstanding software systems can be built, but they may fail to suit the needs of the client. Hence, clients are unsatisfied and development projects fail. In this paper we propose a strategy to use the application domain language captured by the Language Extended Lexicon in order to obtain different products related to requirements specification. Products vary from classic requirements which state "the system shall⋯" to products such as Use Cases and User Stories. The strategy focuses on obtaining the initial set of functional requirements. We believe that by minimizing the gap between the problem and the initial set of requirements, we provide engineers with a preliminary product they can work on and refine to reach the quality needed.
