Testing Forms in Web Applications Automatically

Forms enhance both the dynamic and interactive abilities of Web applications and the system complexity. And it is especially important to test forms completely and thoroughly. Therefore, this paper discusses how to carry out the form testing by different methods in the related testing phases. Namely, at first, automatically abstracting forms in the Web pages by parsing the HTML documents; then, ohtai ning the testing data with a certain strategies, such as by requirement specifications, by mining users＇ hefore input informarion or by recording meehanism; and next executing the testing actions automatically due to the well formed test cases; finally, a case study is given to illustrate the convenient and effective of these methods.

Test research and computer simulation analysis of construction state during form finding for suspen-dome system

A novel construction method without scaffold work called as assembly-prestressing form finding loop by loop is presented.Based on the theory of finite displacement,the cycle-forward analysis method is presented for its construction calculation,which adopts the finite element method of generalized geometric nonlinearity combined with the application in the real construction process.By means of the combination of the forward analysis according to real construction sequence and the cycle iteration according to the initial strain increment method of cable force adjustment,the influence of the structural geometric nonlinearity and the loss of prestress are taken into account due to prestressing of tendons in turn and so on.If the initial cable forces derived from the method were used for construction,expected cable forces and shape could be assured easily.Simulation analysis achieved real-time tracking and controlling of the construction status.Finally,according to the procedure and parameters in simulating,a model experimental research on the stage of form finding(namely prestressing)was carried out for suspen-dome structure.The feasibility on the assembly-prestressing form finding method loop by loop was testified.The cycle-forward analysis method was established and numerical simulation was performed,and the results show that it was useful for the design and the construction of similar suspen-dome structure.

A Cross-cultural Examination of the Noise-sensitivity Scale-short Form:Measurement Invariance Testing between the US and Chinese Samples

Unwanted sound that is unpleasant or disruptive to hear, often interpreted as noise, is a widespread environmental pollutant. Similar to other environmental pollutants, this noise incurs a variety of costs to society. Numerous negative health impacts are linked to increases in noise exposure,such as increased cardiovascular risk;and sleep

Building a Sustainable Learning Cycle:The Role of‘the Formative Use of Summative Tests’(FUST)in Promoting Students’Developments

The study employed a descriptive mixed-methods qualitative case study approach.Material and interview-based data were collected from two EFL classes in a private international school in central China.Findings from RQ1 suggest that teacher-made summative tests were largely dependable to the extent that the tests reflect the syllabus-based construct and address students’affective factors.Findings from RQ2 suggest that facilitating factors including in-school continuous professional development(CPD)and teacher collegiality practices may enhance FUST’s prospective role.

On College English Final Exams Within a University

This paper discusses the importance of a well-written college English final exam within a university at the end of each semester, the directive function of such an exam, the valuable informative feedback of the detailed scores, the necessity and importance of informing students of the general format of the exam and types of items as early as possible. It also deals with the importance of formative evaluation, the functions of regular scores, problems in retests that test-makers should pay attention to and the different organizations of test-makers.

Prediction of plane-strain specimen geometry to efficiently obtain a forming limit diagram by Marciniak test

Plane-strain forming limit strain （also known as FLD0） is an important data point on a forming limit diagram （FLD）. The effects of friction coefficients and material parameters on the specimen width associated with the FLDo （W FLD0） in Marciniak test were studied by finite element simulation. WFLD0 was expressed as a function of the Lankford coefficients, n-value, k-value and sheet thickness and validated with various sheet materials. The determination of W FLD0 is of significance not only to reduce iterative attempts to accurately obtain FLDo, but also to obtain a full valid FLD with the least number of test specimens, which largely increases the efficiency and reduces cost to experimentally measure valid FLDs.

Polynomial Tests of Normal Forms and Some Related Results

The following problem is called the everywhere-cover problem:“Given a set of dependencies over a database scheme,is the set of dependencies explicitly given for each relation scheme equivalent to the dependencies implied for that relation scheme?”It is shown that when the everywhere-cover problem has a ‘yes’ answer,examining only the dependencies explicitly given will suffice to test 3NF,BCNF and 4NF of a database scheme.But this does not hold for 2NF.Consequently,in such cases,tests of BCNF and 4NF all take polynomial time.Then a proof is given that test of 3NF of a database scheme is Co-NP-complete,and from this result it is shown that everywhere-cover is also Co-NP-complete when only functional dependencies are allowed.These results lead to doubt the truth of the well believed conjec- ture that no polynomial time algorithm for designing a Iossless BCNF database scheme is likely to exist.

Seguin Form Board as an intelligence tool for young children in an Indian urban slum

Objective:The present study evaluates the concurrent and predictive validity of the Seguin Form Board Test(SFBT)as an intelligence tool for children in low-and middle-income countries.Methods:In a cohort of normal children,followed up in South India,two cross-sectional analyses were done at 3 and 7 years of age on 95 children.The SFBT and Vineland Social Matu-rity Scale(VSMS)were done at 3 years of age and Malin’s Intelligence Scale for Indian Children(MISIC)and the VSMS were done at 7 years of age,and the results were compared for concurrent and predictive validity for the SFBT.Results:Intelligence quotient and social quotient had positive correlations at 3 years of age,indicating fair concurrent validity.The SFBT done at around 3 years of age had good positive cor-relation with MISIC at 7 years of age,indicating good predictive validity.Conclusion:This study shows the utility of the SFBT as a community-based intelligence tool with acceptable concurrent and predictive validity.

An algorithm for computing the factor ring of an ideal in a Dedekind domain with finite rank

We give an algorithm for computing the factor ring of a given ideal in a Dedekind domain with finite rank, which runs in deterministic and polynomial time. We provide two applications of the algorithm:judging whether a given ideal is prime or prime power. The main algorithm is based on basis representation of finite rings which is computed via Hermite and Smith normal forms.
