We present a pattern system/or security requirements engineering, consisting of security problem frames and concretized security problem frames. These are special kinds of problem frames that serve to structure, characterize, analyze, and finally solve software development problems in the area of software and system security. We equip each frame with formal preconditions and postconditions. The analysis of these conditions results in a pattern system that explicitly shows the dependencies between the different frames. Moreover, we indicate related frames, which are commonly used together with the considered frame. Hence, our approach helps security engineers to avoid omissions and to cover all security requirements that are relevant for a given problem

Using software components has become a widely used development technique for building large enterprise systems. However in practice, component applications are still primarily built using simple component models and advanced component models offering valuable features like component nesting, multiple communication styles, behavior validation, etc. are omitted (by industry in particular). Based on our experience, such an omitting is mainly caused due to usually unbalanced semantics of these advanced features. In this paper, we present a "next-generation" component model SOFA 2.0, which in particular aims at a proper support of such advanced features.
Random Testing (RT) is a fundamental technique of software testing. Adaptive Random Testing (ART) has recently been developed as an enhancement of RT that has better fault detection effectiveness. Several methods (alg...

A method of recording the fetal electrocardiogram (ECG) and heart rate (HR) is described. An abdominal lead and a thoracic lead were used to measure the fetal ECG and maternal ECG, respectively. The maternal component in the abdominal lead measurement was estimated by a digital adaptive filter using the thoracic lead measurement as a reference. By suppressing the estimated maternal components in the abdominal lead, the fetal ECG could be detected. The beat-by-beat fetal QRS complex peaks were determined by a digital matched filter from the fetal ECG enhanced in this way. The method was trialed in 10 pregnant Holstein cows at gestational periods ranging from 136 to 224 days. The results show that this method can extract the fetal ECG and determine the fetal HR from the raw noisy measurement data. The results suggest that the method would have applicability in monitoring fetal ECG as well as providing a non-invasive, continuous HR profile during gestation, which will enable better understanding of the development of cattle fetuses before delivery.

The Road Transport Department of Malaysia has endorsed a specification for car plates that includes the font and size of characters that must be followed by car owners. However, there are cases where this specification is not followed. This will cause problems in the recognition phase because the existing systems will find difficulty in recognizing characters in car plates. To ensure the recognition can be done correctly, the thinning and feature extraction phases should be done successfully by applying appropriate techniques. Inappropriate technique applied during thinning phase can cause wrong value derived during the feature extraction phase that use statistical method and thus affected the process of car plate recognition. Therefore, this paper is mainly focused on the thinning process of car plate images where a suitable technique was applied. This technique will produce a successful thin line of characters with a standard size regardless of its various sizes and font types. This standard size then was used as a template to derive a value for each character during feature extraction phase and will be very useful in recognition phase. This paper provided with an analytical overview of the proposed technique and the expected detail outcome for this research.

Nowadays in the textile industry are still used a human naked eyes to detect any kinds of defect on textile webs. The problems occurred when a human has their own limitations on different kind of perceptions in identifying a defect. In this paper, we intend to propose an object classification using a standard deviation value for classifying the defect on textile webs. First we describe the method of image segmentation that we applied in this study which is based on statistical technique. Further, we focus on the features analysis where we divide it into two phases; (1) learning phase and (2) analysis phase. Finally, we have been tested our propose algorithm into 5 (five) different types of textile webs with 500 images for each type of webs. We figure out that this method is suitable for distort and small defect as in textile webs. The details of results from our testing phases will be discussed at the end of this paper.
