Abstract:
An ideal model for credit risk assessment is supposed to select important features and process imbalanced data sets in an effective manner. This paper proposes an integrated method that combines B&B (branch and bound)-based hybrid feature selection (BBHFS) with the imbalanceoriented multiple-classifier ensemble (IOMCE) for imbalanced credit risk assessment and uses the support vector machine (SVM) and the multiple discriminant analysis (MDA) as the base predictor. BBHFS is a hybrid feature selection method that integrates the t-test and B&B with the k-fold crossvalidation method to sea

Abstract:
Feature analysis puts a great impact in determining the various health conditions of mechanical vessels. To achieve balance between traditional feature extraction and the automated feature selection process, a hybrid bag of features (HBoF) is designed for multiclass health state classification of spherical tanks in this paper. The proposed HBoF is composed of (a) the acoustic emission (AE) features and (b) the time and frequency based statistical features. A wrapper-based feature chooser algorithm, Boruta, is utilized to extract the most intrinsic feature set from HBoF. The selective feature m

In order to accurately obtain the seedling emergence rate of breeding sunflower and to assess the quality of sowing as well as the merit of sunflower varieties, a method of extracting the sunflower seedling emergence rate using multi-source remote sensing information from unmanned aerial vehicles is proposed.

The thresholding method was used to segment the excess green image of the visible image into vegetation and non-vegetation, to obtain the center point of the vegetation to generate a buffer, and to mask the

Abstract:
During the past 20 years many works have been done on duplex stainless steel elbows from EDF plants. These elbows are manufactured with cast CF8M material sensitive to thermal ageing and sensitive to cast defects. After an important work the fitness for service has been derived: acceptance of a crack of 10 × 20mm on the outer surface of the elbows in any particular location for all type of design transients: level A, B, C and D, with corresponding safety factors. Consequently, EDF developed a set of material data: • stress-strain curves; • crack initiation laws for cast defects; • crack growth

Abstract:
Abstract Traditionally design geometries are represented using orthographic views which require a human being to interpret them and recognize geometric features to evaluate the design. Solid modeling systems have made the task somewhat easier, but they often require tedious and complex operations using simple geometric primitives to create a model assembly. This has led to investigation of modeling systems which allow the creation of assemblies the way engineers conceive them — as features. To be able to efficiently describe models in terms of features, a rich set of feature descriptors is nec

Abstract:
Given two sets of sequences A and B, the Substring Specific problem is to find all minimum substrings in A having distance at least k for each subsequence in B. This work addresses three new implementations for the Maaß algorithm when the Hamming distance is considered: a naive cubic-time algorithm and two quadratic-time algorithms. We run tests to compare the running time of these implementations and another recently described algorithm implementation that uses the edit distance. In addition, we conducted preliminary testing on a large Tara Ocean database, looking for efficient and effective

Abstract:
Abstract This paper presents systematically a new method for the displacement analysis (DA) of multi-loop spatial linkages (MLSLs) based on ordered simple-opened-chains (SOCs). In performing DA, a MLSL is converted into not a set of base points, a set of isolated links or a tree with/without isolated links in common use, but a weakly coupled MLSL in this paper. The characteristics of the proposed method are: (a) The number of unknowns in the set of equations for displacement analysis (EDA) of a MLSL is reduced to the minimum; (b) All the possible configurations corresponding to a given set of

Abstract:
An approach to develop Proper Orthogonal Decomposition (POD) based reduced order models for systems with local nonlinearities is presented in this paper. This technique is applied to multi-degree of freedom systems of coupled oscillators with isolated nonlinear elements. Typically, reduced order models are obtained using POD modes exclusively. In this work, we explore the suitability of using a combination of POD modes and other physically based “Ritz vectors” to produce the reduced model. The objectives are 1). to improve the accuracy of the reduced order differential equation model and 2). t

Abstract:
In a real-world data set there is always the possibility, rather high in our opinion, that different features may have different degrees of relevance. Most machine learning algorithms deal with this fact by either selecting or deselecting features in the data preprocessing phase. However, we maintain that even among relevant features there may be different degrees of relevance, and this should be taken into account during the clustering process. With over 50 years of history, K-Means is arguably the most popular partitional clustering algorithm there is. The first K-Means based clustering algo

Abstract:
Seton Lake is a freshwater fiord located in southwestern British Columbia, roughly 4 km west of Lillooet and 250 km north-northeast of Vancouver. Located in the Coast Mountains, it is an alpine lake about 22-km long and roughly 1-1.5 km wide. It is separated from nearby Anderson Lake, located to the west, by a large pre-historic rock avalanche deposit at Seton Portage. The lake stands at about 243 m above sea level and is up to about 150 m deep (BC gov., 1953). Water level is controlled by a hydroelectric dam (i.e., Seton dam) located at the eastern end of the lake. Here, the lake drains east

Abstract:
Subsea pipelines and flow lines are periodically subjected to damaging events such as anchor impacts that result in massive pipeline movements, dropped object damage, internal/external corrosion damage, etc. Knowing how to assess these damage events is often challenging, especially considering the potential for product release. The cost of production shut-ins can be significant and avoiding un-necessary shut-ins is desirable. While most pipeline operators have company-level procedures and programs in place for responding to pipeline emergencies, at the current time there is no single resource

Evidence is essential for effective policymaking at all levels of government. Connecting decisionmakers to the wealth of research generated by universities is critical to ensuring that they can access, interpret and apply that evidence to inform policy development and decisions. In the UK, this requires universities to pay attention to the ways in which they can connect their research knowledge to public policymaking. In many cases, such ‘academic-policy engagement’ is undertaken by ‘third space professionals’ (Whitchurch, 2008, 2013) working at the interface between academic research and publ
