The XYZ micropositioning stages are perhaps the most commonly used components in free-space optical systems built on laboratory optical benches. They are extensively used to position optical elements, perform optical alignment, or fine-tune optical circuits. Such optical systems, however, are bulky and difficult to integrate with conventional technologies. The micromachining technology has been...

in present investigation the biological leaching of aluminum by isolated fungi from red mud, the main waste product of the alkaline extraction of al from bauxite was studied. biological leaching experiments were carried out using indigenous, date and orange specimen fungi, aspergillus niger, penicillium simplicissimum notatum. savored dextrose chloramphenicol agar (sda) was used as medium for t...

Service engineering and Service-Oriented Architectures (SOAs) have recently been embraced by both industry and research, as they promise high reusability and maintainability, and a flexible environment for future changes in business requirements and workflows. In this paper, we present a model-driven service engineering approach called the SENSORIA Development Approach (SDA). The SENSORIA proje...

Pretraining is widely used in deep neutral network and one of the most famous pretraining models is Deep Belief Network (DBN). The optimization formulas are different during the pretraining process for different pretraining models. In this paper, we pretrained deep neutral network by different pretraining models and hence investigated the difference between DBN and Stacked Denoising Autoencoder...

This paper presents a hybrid spiral dynamic algorithm with super-opposition (SOSDA) strategy. An improvement on the (SDA), this method uses concept centered opposition-based learning, which is used to evaluate fitness of agents at opposite location current solution. The SDA simple-structured and deterministic type algorithm, also performs competitively in terms solution accuracy. However, its c...

We examine a standard factory scheduling problem with stochastic processing and setup times, minimizing the expectation of the weighted number of tardy jobs. Because the costs of operators in the schedule are stochastic and sequence dependent, standard dynamic programming algorithms such as A* may fail to find the optimal schedule. The SDA * (Stochastic Dominance A*) algo­ rithm remedies this d...

The T-palindromic quadratic eigenvalue problem (λB + λC + A)x = 0, with A,B,C ∈ Cn×n, C = C and B = A, governs the vibration behavior of trains. One way to solve the problem is to apply a structure-preserving doubling algorithm (SDA) to the nonlinear matrix equation (NME) X + BX−1A = C and “square-root” the matrix quadratic involved. In this paper, we generalize the SDA for the solution of (odd...

This paper analyses the vulnerability of a Radio Frequency IDentification (RFID) equipped distribution centre (DC) of a supply chain against the Statistical Disclosure Attack (SDA). We built a simulation model to assess the success probabilities of the attack against differently configured distribution centres and attackers. The success probability of an SDA against a DC varies, depending on th...

The restoration of edentulous space or hopeless teeth with implant-supported restorations can involve extensive time, effort, and financial commitment. This article presents a case of a debilitated dentition that was restored by using the shortened dental arch (SDA) concept in a comprehensive implant restoration. An SDA design was used to replace removable partial dentures with multiple nonspli...
